Description

吸收性物品absorbent articles

技术领域technical field

本公开涉及吸收性物品。The present disclosure relates to absorbent articles.

背景技术Background technique

在一次性尿布、尿垫、生理用品等吸收性物品中,存在对穿戴者的皮肤所抵接的片赋予弱酸性的性质的吸收性物品(例如,参照日本特开2019-97660)。由此,在穿戴者排尿后,能够利用片的pH调整成分来中和尿所含有的氨等碱成分。因此,能够将穿戴者的皮肤从弱酸性维持为中性,能够抑制产生皮肤问题。Among absorbent articles such as disposable diapers, changing pads, and sanitary products, there are absorbent articles that impart a weakly acidic property to a sheet against which the wearer's skin is in contact (for example, see Japanese Patent Laid-Open No. 2019-97660). Thereby, after the wearer urinates, alkali components such as ammonia contained in the urine can be neutralized by the pH adjusting component of the sheet. Therefore, the wearer's skin can be maintained from weakly acidic to neutral, and the occurrence of skin problems can be suppressed.

另外,在一次性尿布、尿垫、生理用品等吸收性物品中,例如存在在吸收体与形成外表面的罩片之间设置有尿检测体的吸收性物品。尿检测体例如通过将配合有pH指示剂的热熔粘接剂涂布在片上而形成,通过与尿的水分、pH反应而变色,从而能够将穿戴者的排尿通知给他人(例如,参照日本特开2001-327532、日本特开2003-190209)。In addition, among absorbent articles such as disposable diapers, urine pads, and sanitary products, for example, there are absorbent articles in which a urine detection body is provided between an absorber and a cover sheet that forms an outer surface. The urine sample is formed by, for example, applying a hot-melt adhesive containing a pH indicator to a sheet, and reacts with the moisture and pH of the urine to change color, so that it is possible to notify others of the wearer's urination (for example, refer to Japan). Laid-Open No. 2001-327532, Japanese Laid-Open No. 2003-190209).

The embodiment shown below is an example of the embodiment of the present invention, and the technical scope of the present invention is not limited to the following aspects.

<第1实施方式><First Embodiment>

图1是实施方式的内裤型一次性尿布(以下,简称为“尿布”)的立体图。关于本申请中使用的方向的用语是指在将尿布1穿戴于穿戴者的状态(以下,简称为“穿戴状态”)下与该穿戴者的前后左右一致的方向。例如,在本申请中称为左右方向的情况下,是指在尿布1的穿戴状态下与穿戴者的左右一致的方向。FIG. 1 is a perspective view of an underpants-type disposable diaper (hereinafter, simply referred to as a “diaper”) according to an embodiment. The term about the direction used in this application means the direction which corresponds to the front, back, left and right of the wearer in a state in which the diaper 1 is worn on the wearer (hereinafter, simply referred to as "wearing state"). For example, when it is called the left-right direction in this application, it means the direction which corresponds to the right and left of the wearer in the wearing state of the diaper 1 .

在本实施方式中,作为吸收性物品的一例,例示了具有供穿戴者的腹围进入的开口部、和供穿戴者的左下肢以及右下肢插通的左右一对的开口部的筒状构造的内裤型一次性尿布,但本申请中所说的“吸收性物品”并不限定于内裤型一次性尿布。在本申请中所说的“吸收性物品”中,例如,包括通过将固定于从前身到后身覆盖穿戴者的下裆(阴部)的片状的构件的一端部附近的带粘贴于该片状的构件的另一端部附近而形成筒状构造的带型一次性尿布等、能够包裹腹围和下裆的各种形态的吸收性物品。In the present embodiment, as an example of the absorbent article, a cylindrical structure having an opening into which the abdominal circumference of the wearer enters, and a pair of left and right openings through which the wearer's left and right lower extremities are inserted is exemplified. Underpants-type disposable diapers, but the "absorbent article" referred to in this application is not limited to underpants-type disposable diapers. The "absorbent article" referred to in the present application includes, for example, a tape fixed to the sheet-like member covering the wearer's crotch (pubic region) from the front to the back near one end of the sheet-like member. Absorbent articles of various forms that can wrap around the girth and the crotch, such as a belt-type disposable diaper having a tubular structure in the vicinity of the other end of the shaped member.

另外,在尿布1中,将穿戴状态下的从前身连结后身的方向设为长度方向。另外,在尿布1的穿戴状态下,将朝向穿戴者的皮肤的一侧(穿戴状态下为内侧)设为皮肤面侧,将皮肤面侧的相反侧(穿戴状态下为外侧)设为非皮肤面侧。而且,将连结皮肤面侧与非皮肤面侧的方向设为厚度方向,将与长度方向和厚度方向均正交的方向设为宽度方向。此外,将从厚度方向观察的情况设为平面观察。Moreover, in the diaper 1, the direction which connects the back body from the front body in the wearing state is made into a longitudinal direction. In addition, in the wearing state of the diaper 1, the side facing the wearer's skin (inner in the wearing state) is referred to as the skin surface side, and the side opposite to the skin surface side (outer side in the wearing state) is referred to as the non-skin face side. Moreover, let the direction connecting the skin surface side and the non-skin surface side be the thickness direction, and let the direction orthogonal to both the longitudinal direction and the thickness direction be the width direction. In addition, when viewed from the thickness direction, it is assumed to be a plane view.

尿布1具有:下裆区域1B,所述下裆区域1B是与在穿戴状态下覆盖穿戴者的下裆部(阴部)的下裆区域对应的部位;前身区域1F,所述前身区域1F是穿戴者的腰围(日文:胴周り)处的与前身对应的部位且用于覆盖穿戴者的腹部侧;以及后身区域1R,所述后身区域1R是穿戴者的腰围处的与后身对应的部位且用于覆盖穿戴者的背部侧。在此,前身区域1F位于下裆区域1B的前侧,后身区域1R位于下裆区域1B的后侧。本实施方式的尿布1是内裤型的一次性尿布,因此前身区域1F的左侧的边缘与后身区域1R的左侧的边缘相互接合,前身区域1F的右侧的边缘与后身区域1R的右侧的边缘相互接合。因此,在尿布1中,由前身区域1F的上侧的边缘和后身区域1R的上侧的边缘形成躯干开口部(日文:胴開口部)2T。另外,在尿布1中,在未实施上述接合的下裆区域1B的左侧的部位形成有左下肢开口部2L,在下裆区域1B的右侧的部位形成有右下肢开口部2R。并且,当尿布1以穿戴者的左下肢插通于左下肢开口部2L、穿戴者的右下肢插通于右下肢开口部2R且穿戴者的躯干部进入躯干开口部2T的方式被穿戴时,前身区域1F配置于穿戴者的腹部侧,后身区域1R配置于穿戴者的背部侧,左下肢开口部2L和右下肢开口部2R以包围穿戴者的大腿部的状态固定于穿戴者的身体。尿布1以这样的形态固定于穿戴者的身体,因此穿戴者能够在穿戴了尿布1的状态下站立行走。The diaper 1 has a crotch region 1B that corresponds to a crotch region that covers a wearer's crotch (pudendal region) in a wearing state, and a front body region 1F that is worn The part corresponding to the front body at the waist circumference of the wearer (Japanese: 貴 circumference り) and used to cover the abdomen side of the wearer; area and is used to cover the back side of the wearer. Here, the front body region 1F is positioned on the front side of the crotch region 1B, and the rear body region 1R is positioned on the rear side of the crotch region 1B. Since the diaper 1 of the present embodiment is a pant-type disposable diaper, the left edge of the front body region 1F and the left edge of the back body region 1R are joined to each other, and the right edge of the front body region 1F and the back body region 1R are joined to each other. The edges on the right side meet each other. Therefore, in the diaper 1, the trunk opening (Japanese: trunk opening) 2T is formed by the upper edge of the front body region 1F and the upper edge of the back body region 1R. Moreover, in the diaper 1, the left lower extremity opening 2L is formed on the left side of the crotch region 1B where the joining is not performed, and the right lower extremity opening 2R is formed on the right side of the crotch region 1B. When the diaper 1 is worn in such a manner that the left lower limb of the wearer is inserted into the left lower limb opening 2L, the right lower limb of the wearer is inserted into the right lower limb opening 2R, and the wearer's trunk is inserted into the trunk opening 2T, The front body region 1F is arranged on the abdomen side of the wearer, the back body region 1R is arranged on the back side of the wearer, and the left lower extremity opening 2L and the right lower extremity opening 2R are fixed to the wearer's body in a state of surrounding the wearer's thighs . Since the diaper 1 is fixed to the wearer's body in such a form, the wearer can stand and walk while wearing the diaper 1 .

在尿布1中,主要以下裆区域1B附近为中心配置有能够吸收并保持液体的吸收体。另外,在尿布1中,为了抑制在尿布1与穿戴者的皮肤之间形成成为液体的流出路径的间隙,在包围穿戴者的左下肢的大腿部的左下肢开口部2L设置有立体褶裥3BL,在包围穿戴者的右下肢的大腿部的右下肢开口部2R设置有立体褶裥3BR,在包围穿戴者的腹围的部位设置有腰部褶裥3R。另外,在腰部褶裥3R的下裆区域1B侧形成有腹部褶裥(日文:タミーギャザー)3T(本申请中所说的“第1伸缩部”的一例)。立体褶裥3BL、3BR、腰部褶裥3R及腹部褶裥通过弹性构件的弹性力而紧贴于穿戴者的皮肤。因此,从穿戴者的阴部排出的排泄液几乎不会从尿布1漏出而被尿布1的吸收体吸收。此外,作为弹性构件,能够适当选择线状、带状的橡胶等,在本实施方式中采用线状橡胶(线状的橡胶)。In the diaper 1, the absorber which can absorb and hold|maintain liquid is mainly arrange|positioned centering on the crotch region 1B vicinity. In addition, in the diaper 1, three-dimensional gathers are provided at the left lower limb opening 2L surrounding the thigh of the wearer's left lower limb in order to suppress the formation of a gap between the diaper 1 and the wearer's skin, which becomes a liquid outflow path. In 3BL, the three-dimensional gathers 3BR are provided in the right lower limb opening 2R surrounding the thigh of the wearer's right lower limb, and the waist gathers 3R are provided in the region surrounding the wearer's abdomen. In addition, belly gathers (Japanese: タミーギャザー) 3T (an example of the "1st expansion-contraction portion" as used in the present application) are formed on the crotch region 1B side of the waist gathers 3R. The three-dimensional gathers 3BL, 3BR, the waist gathers 3R, and the abdomen gathers are in close contact with the wearer's skin by the elastic force of the elastic member. Therefore, the excretion fluid discharged from the wearer's pubic area hardly leaks from the diaper 1 and is absorbed by the absorber of the diaper 1 . In addition, as the elastic member, a wire-shaped rubber, a belt-shaped rubber, or the like can be appropriately selected, and a wire-shaped rubber (wire-shaped rubber) is used in the present embodiment.

图2是实施方式的尿布1的分解立体图。另外,图3A和图3B是示意性地示出将第1实施方式的尿布1展开并伸长的状态的图。图3A示意性地示出从左侧观察展开并伸长的状态的尿布1时的内部构造。图3B示意性地示出展开并伸长的状态的尿布1的平面图。Fig. 2 is an exploded perspective view of the diaper 1 according to the embodiment. 3A and 3B are diagrams schematically showing a state in which the diaper 1 of the first embodiment is unfolded and extended. FIG. 3A schematically shows the internal structure of the diaper 1 in the unfolded and extended state when viewed from the left side. FIG. 3B schematically shows a plan view of the diaper 1 in the unfolded and stretched state.

尿布1具有在穿戴状态下形成外表面的罩片4F、4R和垫罩片(英文:pad coversheet)6。罩片4F主要形成尿布1的前身区域1F的外表面。另外,垫罩片6主要形成尿布1的下裆区域1B的外表面。另外,罩片4R主要形成尿布1的后身区域1R的外表面。罩片4F、4R和垫罩片6是为了提高尿布1的外表面的加强、手感而设置的,例如,为了抑制排泄物的泄漏,能够使用由不透液性的热塑性树脂构成的无纺布作为其材料。在此,作为不透液性的热塑性树脂,能够例示聚乙烯(PE)、聚丙烯(PP)等。另外,在不透液性的片中,为了发挥不透液性和透湿性,也可以形成有多个0.1~数μm左右的微细的孔。另外,为了提高腰围处的通气性,罩片4F、4R也可以局部或整面地形成有多个孔。The diaper 1 has cover sheets 4F and 4R and a pad cover sheet (English: pad cover sheet) 6 which form an outer surface in a wearing state. The cover sheet 4F mainly forms the outer surface of the front body region 1F of the diaper 1 . In addition, the cover sheet 6 mainly forms the outer surface of the crotch region 1B of the diaper 1 . In addition, the cover sheet 4R mainly forms the outer surface of the back body region 1R of the diaper 1 . The cover sheets 4F, 4R and the pad cover sheet 6 are provided to improve the reinforcement and feel of the outer surface of the diaper 1. For example, in order to suppress leakage of excrement, a nonwoven fabric made of a liquid-impermeable thermoplastic resin can be used. as its material. Here, as the liquid-impermeable thermoplastic resin, polyethylene (PE), polypropylene (PP), and the like can be exemplified. In addition, in the liquid-impermeable sheet, in order to exhibit liquid-impermeability and moisture-permeability, a plurality of fine pores of about 0.1 to several μm may be formed. Moreover, in order to improve the ventilation property in the waistline, the cover sheets 4F and 4R may be partially or entirely formed with a plurality of holes.

另外,尿布1具有层叠于罩片4F的皮肤面侧的内罩片5F和层叠于罩片4R的皮肤面侧的内罩片5R。内罩片5F是具有与罩片4F中的比后述的线状孔眼(日文:ミシン目)4F6靠下裆区域1B侧的部分一致的形状的片状的构件。内罩片5R也与内罩片5F同样,是具有与内罩片5R中的比后述的线状孔眼4R6靠下裆区域1B侧的部分一致的形状的片状的构件。Moreover, the diaper 1 has the inner cover sheet 5F laminated|stacked on the skin surface side of the cover sheet 4F, and the inner cover sheet 5R laminated|stacked on the skin surface side of the cover sheet 4R. The inner cover sheet 5F is a sheet-like member having a shape corresponding to a portion on the crotch region 1B side of the cover sheet 4F with respect to a linear eyelet (Japanese: Michin mesh) 4F6 described later. Like the inner cover sheet 5F, the inner cover sheet 5R is also a sheet-like member having a shape corresponding to a portion of the inner cover sheet 5R on the crotch region 1B side than the linear eyelet 4R6 described later.

另外,尿布1具有在垫罩片6的皮肤面侧依次层叠的背片7、吸收体8、顶片9。垫罩片6是在长度方向上具有从穿戴者的前身经由下裆而到达后身的长度且在与该长度方向正交的宽度方向上具有预定的宽度的大致长方体的片。另外,背片7、吸收体8、顶片9都是与垫罩片6同样地具有大致长方形的外观的片状的构件,在长度方向与垫罩片6的长度方向一致的状态下相对于垫罩片6依次层叠。此外,垫罩片6、背片7、吸收体8、顶片9的长度方向与尿布1的长度方向一致,垫罩片6、背片7、吸收体8、顶片9的宽度方向与尿布1的宽度方向一致。Moreover, the diaper 1 has the back sheet 7, the absorber 8, and the top sheet 9 laminated|stacked in this order on the skin surface side of the cover sheet 6. The pad cover sheet 6 is a substantially rectangular parallelepiped sheet having a length from the front body of the wearer to the back body through the crotch in the longitudinal direction and a predetermined width in the width direction orthogonal to the longitudinal direction. In addition, the back sheet 7 , the absorber 8 , and the top sheet 9 are all sheet-like members having a substantially rectangular appearance like the cover sheet 6 , and are relative to each other in a state where the longitudinal direction coincides with the longitudinal direction of the cover sheet 6 The spacer sheets 6 are stacked in sequence. In addition, the length direction of the pad cover sheet 6, the back sheet 7, the absorber 8 and the top sheet 9 is consistent with the length direction of the diaper 1, and the width direction of the pad cover sheet 6, the back sheet 7, the absorber 8 and the top sheet 9 is the same as that of the diaper. 1 has the same width direction.

背片7是为了抑制排泄物的泄漏而以不透液性的热塑性树脂为材料而形成的片。另外,顶片9是以覆盖吸收体8的吸水面的方式配置于穿戴者的皮肤面侧的片状的构件。该顶片9的一部分或全部具有透液性。因此,在尿布1的穿戴状态下,从穿戴者排泄出的液体通过能够与穿戴者的皮肤接触的顶片9而浸入到吸收体8,在那里被吸收。作为透液性的片,例如可列举织布、无纺布、多孔质膜。另外,顶片9也可以具有亲水性。The back sheet 7 is a sheet formed of a liquid-impermeable thermoplastic resin in order to suppress leakage of excrement. Moreover, the top sheet 9 is a sheet-like member arrange|positioned on the skin surface side of a wearer so that the water absorption surface of the absorber 8 may be covered. A part or the whole of this top sheet 9 is liquid-permeable. Therefore, in the wearing state of the diaper 1, the liquid excreted from the wearer penetrates into the absorber 8 through the top sheet 9 which can be brought into contact with the wearer's skin, and is absorbed there. As a liquid-permeable sheet, a woven fabric, a nonwoven fabric, and a porous membrane are mentioned, for example. In addition, the top sheet 9 may have hydrophilicity.

另外,顶片9具有多层构造。图4A是从皮肤面侧观察顶片9的第1例的平面图,图4B是将图4A所示的顶片9的第1例用A-A线剖切的情况的剖视图。另外,图5A是从皮肤面侧观察顶片9的第2例的平面图,图5B是将图5A所示的顶片9的第2例用B-B线剖切的情况的剖视图。In addition, the topsheet 9 has a multi-layer construction. 4A is a plan view of the first example of the top sheet 9 viewed from the skin surface side, and FIG. 4B is a cross-sectional view of the first example of the top sheet 9 shown in FIG. 4A cut along the line A-A. 5A is a plan view of the second example of the top sheet 9 viewed from the skin surface side, and FIG. 5B is a cross-sectional view of the second example of the top sheet 9 shown in FIG. 5A cut along the line B-B.

如图4A和图4B以及图5A和图5B所示,顶片9具有外顶片9A和内顶片9B。外顶片9A(本申请中所说的“第1片”的一例)是与穿戴者的皮肤抵接的透液性的片,内顶片9B(本申请中所说的“第2片”的一例)是配置在外顶片9A与吸收体8之间的透液性的片。内顶片9B具有中性的性质。另一方面,外顶片9A包含pH调整成分且具有弱酸性的性质。作为pH调整成分,使用有机酸、例如安全性高且在尿布1的使用前的状态下实质上无臭的苹果酸或柠檬酸。外顶片9A是通过在内顶片9B那样的中性的片上涂布含有有机酸的药液而制成的。As shown in Figures 4A and 4B and Figures 5A and 5B, the topsheet 9 has an outer topsheet 9A and an inner topsheet 9B. The outer topsheet 9A (an example of the "1st sheet" said in this application) is a liquid-permeable sheet that abuts against the wearer's skin, and the inner topsheet 9B (the "2nd sheet" said in this application) An example) is a liquid-permeable sheet|seat arrange|positioned between the outer top sheet 9A and the absorber 8. The inner topsheet 9B has neutral properties. On the other hand, the outer top sheet 9A contains a pH adjustment component and has a weakly acidic property. As a pH adjustment component, an organic acid, for example, malic acid or citric acid which is highly safe and is substantially odorless in the state before use of the diaper 1 is used. The outer top sheet 9A is produced by applying a chemical solution containing an organic acid to a neutral sheet such as the inner top sheet 9B.

另外,在顶片9的第1例中,如图4A和图4B所示,外顶片9A的片面积比内顶片9B的片面积大,通过热熔接或超声波熔接而在内顶片9B的皮肤面侧的表面呈沿尿布1的长度方向延伸的波浪线状熔接。而且,外顶片9A在尿布1的宽度方向上隔开间隔地在多个部位熔接于内顶片9B。由此,外顶片9A中的朝向内顶片9B突出的突出部(熔接部WL)在宽度方向上隔开间隔地在多个部位支承平坦的内顶片9B,在外顶片9A与内顶片9B之间形成空间。其结果是,在从皮肤面侧观察顶片9时,由外顶片9A的熔接部WL和熔接部WL以外的部分,在外顶片9A形成通过压纹加工而形成的花纹。In addition, in the 1st example of the top sheet 9, as shown in Figure 4A and Figure 4B, the sheet area of the outer top sheet 9A is larger than the sheet area of the inner top sheet 9B, and the inner top sheet 9B is formed by thermal fusion or ultrasonic welding. The surface on the skin side is welded in the shape of a wavy line extending in the longitudinal direction of the diaper 1 . And the outer top sheet 9A is welded to the inner top sheet 9B at a plurality of locations at intervals in the width direction of the diaper 1 . Thus, the protrusion (welding portion WL) protruding toward the inner top sheet 9B in the outer top sheet 9A supports the flat inner top sheet 9B at a plurality of positions at intervals in the width direction, and the outer top sheet 9A and the inner top sheet 9B Spaces are formed between the sheets 9B. As a result, when the top sheet 9 is viewed from the skin surface side, a pattern formed by embossing is formed in the outer top sheet 9A by the welded portion WL of the outer top sheet 9A and the portion other than the welded portion WL.

另外,在顶片9的第2例中,如图5A、图5B所示,内顶片9B的片面积比外顶片9A的片面积大,通过热熔接或超声波熔接而在外顶片9A的非皮肤面侧的表面呈沿尿布1的长度方向延伸的波浪线状熔接。而且,内顶片9B在宽度方向上隔开间隔地在多个部位熔接于外顶片9A。由此,内顶片9B中的朝向外顶片9A突出的突出部(熔接部WL)在宽度方向上隔开间隔地在多个部位支承平坦的外顶片9A,在外顶片9A与内顶片9B之间形成空间。其结果是,在从皮肤面侧观察顶片9时,如图5A中虚线所示,由内顶片9B的熔接部WL和熔接部WL以外的部分形成的花纹形成于内顶片9B。In addition, in the 2nd example of the top sheet 9, as shown in Figure 5A, Figure 5B, the sheet area of the inner top sheet 9B is larger than the sheet area of the outer top sheet 9A, and the outer top sheet 9A is welded by thermal fusion or ultrasonic welding. The surface on the non-skin side is welded in the shape of a wavy line extending in the longitudinal direction of the diaper 1 . Moreover, the inner top sheet 9B is welded to the outer top sheet 9A at a plurality of locations at intervals in the width direction. Thus, the protruding portion (welding portion WL) protruding towards the outer top sheet 9A in the inner top sheet 9B supports the flat outer top sheet 9A at a plurality of positions at intervals in the width direction. Spaces are formed between the sheets 9B. As a result, when the topsheet 9 is viewed from the skin surface side, as shown by the broken line in FIG. 5A , the pattern formed by the welded portion WL of the inner topsheet 9B and the portion other than the welded portion WL is formed on the inner topsheet 9B.

在这些顶片9的多层构造中,由于形成在外顶片9A与内顶片9B之间的空间,皮肤触感变得柔软。而且,在图4A和图4B所示的顶片9的多层构造中,在相邻的熔接部WL之间形成有外顶片9A向皮肤面侧突出的部分(凸状部),凸状部相邻地排列,因此,在穿戴者的皮肤与外顶片9A接触了时,也能够在皮肤与相邻的凸状部之间形成空间(参照图6A)。由此,外顶片9A容易干燥,即使穿戴者的皮肤与外顶片9A接触,外顶片9A也容易维持干燥的状态。In the multilayer construction of these topsheets 9, the skin feel becomes soft due to the space formed between the outer topsheet 9A and the inner topsheet 9B. Furthermore, in the multilayer structure of the top sheet 9 shown in FIGS. 4A and 4B , a portion (convex portion) that protrudes from the outer top sheet 9A toward the skin surface side is formed between the adjacent welding portions WL, and the convex portion is formed. Since the parts are arranged adjacently, even when the wearer's skin is in contact with the outer top sheet 9A, a space can be formed between the skin and the adjacent convex parts (see FIG. 6A ). Thereby, the outer top sheet 9A is easily dried, and even if the wearer's skin comes into contact with the outer top sheet 9A, the outer top sheet 9A is easily maintained in a dry state.

此外,在上述的顶片9的多层构造中,可以是,不仅外顶片9A显示出弱酸性,内顶片9B也显示出弱酸性。另外,熔接部WL的延伸方向不限定于尿布1的长度方向。例如,熔接部WL的延伸方向可以是尿布1的宽度方向,另外也可以是长度方向及宽度方向双方。另外,熔接部WL的形状并不限定于由曲线构成的波浪线状。例如,熔接部WL的形状也可以是由直线构成的折线状。而且,熔接部WL的形状只要在外顶片9A与内顶片9B之间形成空间即可,并不限定于线状。例如,熔接部WL的形状也可以是点状。另外,外顶片9A与内顶片9B的接合并不限定于热熔接或超声波熔接。例如,这些片9A、9B的接合也可以是使用了热熔粘接剂的粘接。In addition, in the multilayer structure of the top sheet 9 described above, not only the outer top sheet 9A but also the inner top sheet 9B may exhibit weak acidity. In addition, the extending direction of the welding part WL is not limited to the longitudinal direction of the diaper 1 . For example, the extending direction of the welded portion WL may be the width direction of the diaper 1, or may be both the longitudinal direction and the width direction. In addition, the shape of the welding part WL is not limited to the wavy line shape which consists of a curve. For example, the shape of the welded portion WL may be a zigzag shape composed of straight lines. Moreover, the shape of the welding part WL should just form a space between the outer top sheet 9A and the inner top sheet 9B, and is not limited to a linear shape. For example, the shape of the welded portion WL may be a dot shape. In addition, the bonding of the outer top sheet 9A and the inner top sheet 9B is not limited to thermal welding or ultrasonic welding. For example, the bonding of these sheets 9A and 9B may be bonding using a hot melt adhesive.

吸收体8具有使能够吸收并保持水的具有交联构造的亲水性的高吸收性聚合物等粒状的吸收性树脂保持于纸浆纤维、人造纤维或棉纤维这样的纤维素系纤维的短纤维、对聚乙烯、聚丙烯或聚对苯二甲酸乙二醇酯等的合成纤维实施亲水化处理后的短纤维的间隙的构造。因此,当吸收体8吸收从穿戴者排泄出的液体时,使保持于短纤维内的间隙的吸收性树脂溶胀而将该液体保持于短纤维内。吸收体8可以是由1张垫子(英文:mat)构成的单层构造,也可以是将多张垫子重叠而成的层叠构造。另外,吸收体8能够采取与目的相应的适当的形状。作为吸收体8的形状,例如可列举矩形状、中央部附近缩窄的沙漏型、其他各种形状。The absorber 8 has short fibers of cellulose-based fibers such as pulp fibers, rayon fibers, or cotton fibers that hold granular absorbent resins such as hydrophilic superabsorbent polymers having a cross-linked structure capable of absorbing and retaining water. , The structure of the gap between short fibers after hydrophilizing synthetic fibers such as polyethylene, polypropylene, or polyethylene terephthalate. Therefore, when the absorber 8 absorbs the liquid excreted from the wearer, the absorbent resin held in the gaps in the short fibers is swelled and the liquid is held in the short fibers. The absorber 8 may have a single-layer structure composed of one mat (English: mat), or may have a laminated structure in which a plurality of mats are stacked. In addition, the absorber 8 can take an appropriate shape according to the purpose. Examples of the shape of the absorber 8 include a rectangular shape, an hourglass shape narrowed in the vicinity of the central portion, and various other shapes.

背片7、吸收体8、顶片9均从前身区域1F延伸至后身区域1R。因此,当利用层叠有背片7、吸收体8及顶片9的垫罩片6覆盖穿戴者的阴部(下裆)时,背片7、吸收体8、顶片9的各长度方向的两端部成为位于穿戴者的腹侧和背侧的状态。即,穿戴者的阴部成为从穿戴者的腹侧到背侧被吸收体8覆盖的状态。因此,不管穿戴者以将腹部朝向下方的姿势和将背部朝向下方的姿势中的哪个姿势将液体向体外排出,排出的液体都会经由顶片9与吸收体8接触。The back sheet 7, the absorber 8, and the top sheet 9 all extend from the front body region 1F to the back body region 1R. Therefore, when the back sheet 7, the absorber 8 and the top sheet 9 are stacked with the pad cover sheet 6 to cover the wearer's pubic part (crotch), the two longitudinal directions of the back sheet 7, the absorber 8 and the top sheet 9 are The ends are positioned on the wearer's ventral and backsides. That is, the pubic area of the wearer is in a state covered by the absorber 8 from the abdomen to the back of the wearer. Therefore, the discharged liquid comes into contact with the absorber 8 via the top sheet 9 regardless of whether the wearer discharges the liquid to the outside of the body in either the posture with the abdomen facing downward or the posture with the back facing downward.

另外,尿布1具有用于形成上述的立体褶裥3BL、3BR的细长的带状的侧片10L、10R。侧片10L、10R设置于顶片9的长边的部分。并且,在侧片10L、10R,沿着长度方向粘接有线状橡胶10L1、10R1。因此,当通过将成为前身区域1F的左侧的边缘的罩片4F的边缘4F7与成为后身区域1R的左侧的边缘的罩片4R的边缘4R7相互接合,并且将成为前身区域1F的右侧的边缘的罩片4F的边缘4F8与成为后身区域1R的右侧的边缘的罩片4R的边缘4R8相互接合,从而成为图1所示那样的完成状态的尿布1时,侧片10L、10R被线状橡胶10L1、10R1的收缩力在长度方向上拉近并沿着折回线10L2、10R2从顶片9立起。其结果是,形成防止液体从左下肢开口部2L及右下肢开口部2R流出的立体褶裥3BL、3BR。此外,罩片4F中的边缘4F7和罩片4R中的边缘4R7、罩片4F中的边缘4F8和罩片4R中的边缘4R8的接合方法没有特别限定,例如能够通过热封、高频密封、超声波密封等来进行。Moreover, the diaper 1 has elongated strip|belt-shaped side panels 10L and 10R for forming the above-mentioned three-dimensional gathers 3BL and 3BR. The side sheets 10L and 10R are provided on the long sides of the top sheet 9 . And the linear rubbers 10L1 and 10R1 are adhered to the side sheets 10L and 10R along the longitudinal direction. Therefore, when the edge 4F7 of the cover piece 4F which becomes the left edge of the front body region 1F and the edge 4R7 of the cover piece 4R which becomes the left edge of the rear body region 1R are joined to each other, the right side of the front body region 1F will be joined. When the edge 4F8 of the cover sheet 4F of the side edge and the edge 4R8 of the cover sheet 4R that becomes the right edge of the back body region 1R are joined to each other, and the diaper 1 in the completed state as shown in FIG. 1 is obtained, the side panels 10L, The 10R is pulled in the longitudinal direction by the shrinkage force of the linear rubbers 10L1 and 10R1, and stands up from the top sheet 9 along the folding lines 10L2 and 10R2. As a result, the three-dimensional gathers 3BL and 3BR which prevent the liquid from flowing out from the left lower limb opening 2L and the right lower limb opening 2R are formed. In addition, the bonding method of the edge 4F7 in the cover sheet 4F, the edge 4R7 in the cover sheet 4R, the edge 4F8 in the cover sheet 4F and the edge 4R8 in the cover sheet 4R is not particularly limited, for example, heat sealing, high frequency sealing, Ultrasonic sealing, etc.

另外,尿布1具有:夹着垫罩片6、背片7、吸收体8、顶片9、侧片10L、10R而层叠于罩片4F的皮肤面侧的通气路形成片11F、以及层叠于罩片4R的皮肤面侧的通气路形成片11R。通气路形成片11F在顶片9的长度方向上的一端侧与罩片4F重叠。另外,通气路形成片11R在顶片9的长度方向上的另一端侧与罩片4R重叠。此外,本申请中片重叠的状态并不限定于重叠的片彼此在相互整面接触的状态下重叠的形态,是包含片的一部分彼此重叠的形态的概念。例如,通气路形成片11F以垫罩片6的长度方向上的一端侧的一部分与罩片4F的一部分接触的状态重叠。Moreover, the diaper 1 has the air passage forming sheet 11F laminated on the skin surface side of the cover sheet 4F with the pad cover sheet 6, the back sheet 7, the absorber 8, the top sheet 9, the side sheets 10L, 10R interposed therebetween, and the ventilation passage forming sheet 11F laminated on the skin surface side of the cover sheet 4F. The air passage forming sheet 11R on the skin surface side of the cover sheet 4R. The air passage forming sheet 11F overlaps with the cover sheet 4F at one end side in the longitudinal direction of the top sheet 9 . Moreover, the ventilation passage forming sheet 11R overlaps with the cover sheet 4R on the other end side in the longitudinal direction of the top sheet 9 . In addition, in the present application, the state in which the sheets are overlapped is not limited to the form in which the overlapped sheets are in contact with each other over the entire surface, but is a concept including the form in which a part of the sheets overlaps each other. For example, the air passage forming sheet 11F is overlapped in a state where a part of one end side of the cushion cover sheet 6 in the longitudinal direction is in contact with a part of the cover sheet 4F.

在通气路形成片11F,在沿着前身区域1F的上侧的边缘的在左右方向上延伸的区域排列有多个通气用的微细的通气孔11F1。在通气路形成片11R上也与通气路形成片11F同样地排列有多个通气孔11R1。在此,通气孔是指使片的一个面侧的空间与另一个面侧的空间连通的开口部,其形状没有特别限定。因此,作为通气孔11F1、11R1,例如能够应用圆形、椭圆形、多边形(三角形、四边形等)等形状的开口部。通气孔11F1、11R1向通气路形成片11F、11R的形成并不意味着该通气路形成片11F、11R是不具有通气性的材料,该通气路形成片11F、11R可以是具有通气性的材料和不具有通气性的材料中的任一个。通气路形成片11F、11R优选为具有通气性、透液性的材料,但例如也可以是非通气性的材料。通气孔11F1、11R1的大小、个数并没有特别限定,例如,如果开口面积为0.5~10mm2的孔,则优选形成5~200个左右。In the ventilation passage forming sheet 11F, a plurality of fine ventilation holes 11F1 for ventilation are arranged in a region extending in the left-right direction along the upper edge of the front body region 1F. Similar to the air passage forming sheet 11F, a plurality of air passage holes 11R1 are also arranged in the air passage forming sheet 11R. Here, the ventilation hole refers to an opening that communicates the space on the one surface side of the sheet with the space on the other surface side, and the shape thereof is not particularly limited. Therefore, as the ventilation holes 11F1 and 11R1, for example, openings having shapes such as a circle, an ellipse, and a polygon (triangle, quadrangle, etc.) can be applied. The formation of the ventilation holes 11F1 and 11R1 on the ventilation passage forming sheets 11F and 11R does not mean that the ventilation passage forming sheets 11F and 11R are materials without air permeability, and the ventilation passage forming sheets 11F and 11R may be made of materials with air permeability and any material that does not have air permeability. The air passage forming sheets 11F and 11R are preferably made of a material having air permeability and liquid permeability, but may be a non-air permeability material, for example. The size and number of the ventilation holes 11F1 and 11R1 are not particularly limited, but for example, if the opening area is 0.5 to 10 mm 2 , about 5 to 200 are preferably formed.

如上所述,尿布1除了将吸收体8夹在中间的背片7及顶片9之外,还层叠地形成有罩片4F、4R、通气路形成片11F、11R、垫罩片6、侧片10L、10R,因此可以说具有将上述多个片层叠而成的层叠体。As described above, in the diaper 1, in addition to the back sheet 7 and the top sheet 9 sandwiching the absorber 8, the cover sheets 4F and 4R, the air passage forming sheets 11F and 11R, the pad cover sheet 6 and the side sheets are formed in layers. The sheets 10L and 10R can be said to have a laminate formed by laminating the above-mentioned plurality of sheets.

在此,如图3A和图3B所示,罩片4F的一端侧在线状孔眼4F6处折回。该线状孔眼4F6是由呈直线状切入罩片4F的细切缝形成的通气孔沿着躯干开口部2T的边缘呈虚线状地排列而成的。形成线状孔眼4F6的虚线状的通气孔成为穿戴者的手指无法进入的大小。例如,如果是由5mm以下的长度的切缝形成的通气孔,则一般的婴幼儿的手指进不去。另外,对于线状孔眼4F6,形成虚线状的通气孔的切缝彼此的间隔具有预定的长度,以使得根据尿布1的通常的使用状态而罩片4F不会以线状孔眼4F6为界而切开。虽然也取决于构成罩片4F的材料的强度,但如果是不损害腰围所要求的伸缩性和穿戴感的克重(日文:坪量)为8~50g/m2左右的片,则切缝彼此的间隔优选为2mm以上。Here, as shown in FIGS. 3A and 3B , one end side of the cover piece 4F is folded back at the linear hole 4F6 . The linear perforations 4F6 are formed by the ventilation holes formed by slits that are straightly cut into the cover sheet 4F in a dotted line along the edge of the trunk opening 2T. The dashed-line ventilation holes forming the linear perforations 4F6 have a size in which the wearer's fingers cannot enter. For example, if it is a vent hole formed by slits with a length of 5 mm or less, the fingers of general infants cannot enter. Moreover, about the linear perforation 4F6, the space|interval of the slits which form the ventilation hole of the dashed line has a predetermined length so that the cover sheet 4F is not cut|disconnected by the linear perforation 4F6 according to the normal use state of the diaper 1 open. Although it also depends on the strength of the material constituting the cover sheet 4F, if it is a sheet with a grammage (Japanese: per square meter) of about 8 to 50 g/m 2 without impairing the stretchability and wearing feeling required for the waistline, the slits are cut. The mutual interval is preferably 2 mm or more.

并且,上述的腰部褶裥3R通过将线状橡胶4F2、4F3以伸长状态粘接于罩片4F并将线状橡胶4R2、4R3以伸长状态粘接于罩片4R而形成。粘接于罩片4F的线状橡胶4F2、4F3在折回时沿着形成前身区域1F的上侧的边缘的线状孔眼4F6,从线状孔眼4F6侧起按线状橡胶4F2、线状橡胶4F3的顺序设置。另外,粘接于罩片4R的线状橡胶4R2、4R3也与线状橡胶4F2、4F3同样地,在折回时沿着形成后身区域1R的上侧的边缘的线状孔眼4R6,从线状孔眼4R6侧起按线状橡胶4R2、线状橡胶4R3的顺序设置。因此,线状橡胶4F2、4F3以成为伸缩方向的腰围方向成为尿布1的宽度方向(左右方向)的朝向设置于罩片4F。另外,线状橡胶4R2、4R3以成为伸缩方向的长度方向成为尿布1的宽度方向(左右方向)的朝向设置于罩片4R。因此,当边缘4F7与边缘4R7(参照图2)相互接合且边缘4F8与边缘4R8(参照图2)相互接合时,线状橡胶4F2、4F3和线状橡胶4R2、4R3形成沿着躯干开口部2T环绕的实质上环状的伸缩性构件,发挥使躯干开口部2T向腰围方向收缩的功能。即,线状橡胶4F2、4F3和线状橡胶4R2、4R3发挥收缩力而使尿布1紧贴于穿戴者,防止在尿布1与穿戴者的腹围之间形成间隙。线状橡胶4F2、4F3和线状橡胶4R2、4R3利用在线状橡胶的长度方向上离散地涂布的粘接剂,与罩片4F、4R离散地粘接。将线状橡胶4F2、4F3、4R2、4R3与罩片4F、4R接合的粘接剂可以涂布于线状橡胶4F2、4F3、4R2、4R3,或者也可以涂布于罩片4F、4R。另外,线状橡胶4F2、4F3、4R2、4R3也可以用超声波熔接代替粘接剂而接合于罩片4F、4R。此外,由于线状孔眼4F6的切缝成为穿戴者的手指不会通过的长度,因此指尖不会与线状橡胶4F2、4F3等接触而将线状橡胶切断。And the above-mentioned waist gathers 3R are formed by adhering the linear rubbers 4F2 and 4F3 to the cover sheet 4F in an extended state, and adhering the linear rubbers 4R2 and 4R3 to the cover sheet 4R in an extended state. The linear rubbers 4F2 and 4F3 adhered to the cover sheet 4F are folded back along the linear eyelet 4F6 forming the upper edge of the front body region 1F, and the linear rubber 4F2 and the linear rubber 4F3 are pressed from the linear eyelet 4F6 side. sequence settings. In addition, the linear rubbers 4R2 and 4R3 adhered to the cover sheet 4R, similarly to the linear rubbers 4F2 and 4F3, are folded back along the linear perforations 4R6 forming the upper edge of the rear body region 1R from the linear From the eyelet 4R6 side, the linear rubber 4R2 and the linear rubber 4R3 are provided in this order. Therefore, the linear rubbers 4F2 and 4F3 are provided in the cover sheet 4F in such a direction that the waist direction serving as the expansion-contraction direction becomes the width direction (left-right direction) of the diaper 1 . Moreover, the linear rubbers 4R2 and 4R3 are provided in the cover sheet 4R so that the longitudinal direction which becomes the expansion-contraction direction becomes the width direction (left-right direction) of the diapar 1. Therefore, when the edge 4F7 and the edge 4R7 (refer to FIG. 2 ) are engaged with each other and the edge 4F8 and the edge 4R8 (refer to FIG. 2 ) are engaged with each other, the linear rubbers 4F2 and 4F3 and the linear rubbers 4R2 and 4R3 are formed along the trunk opening 2T. The substantially annular stretchable member that surrounds functions to shrink the trunk opening 2T in the girth direction. That is, the linear rubbers 4F2 and 4F3 and the linear rubbers 4R2 and 4R3 exert a contractile force, so that the diaper 1 is brought into close contact with the wearer, and a gap is prevented from being formed between the diaper 1 and the abdominal circumference of the wearer. The linear rubbers 4F2 and 4F3 and the linear rubbers 4R2 and 4R3 are discretely adhered to the cover sheets 4F and 4R by an adhesive applied discretely in the longitudinal direction of the linear rubbers. The adhesive for joining the linear rubbers 4F2, 4F3, 4R2, 4R3 and the cover sheets 4F, 4R may be applied to the linear rubbers 4F2, 4F3, 4R2, 4R3, or may be applied to the cover sheets 4F, 4R. In addition, the linear rubbers 4F2, 4F3, 4R2, and 4R3 may be joined to the cover sheets 4F and 4R by ultrasonic welding instead of the adhesive. Moreover, since the slit of the linear eyelet 4F6 becomes the length which a wearer's finger does not pass, the thread rubber 4F2, 4F3 etc. are not cut|disconnected by a fingertip coming into contact with the linear rubber.

而且,线状橡胶4F4、4F5(本申请中所说的“第1伸缩性构件”的一例)以伸长状态粘接于罩片4F,线状橡胶4R4、4R5以伸长状态粘接于罩片4R。线状橡胶4F4、4F5是设置于罩片4F中的比线状橡胶4F3靠下裆区域1B侧的区域的伸缩性构件。在尿布1中,利用线状橡胶4F4、4F5、4R4、4R5,在比腰部褶裥3R靠下裆区域1B侧的位置形成有腹部褶裥3T。不过,线状橡胶4F4、4F5与从罩片4F的左端延伸到右端的线状橡胶4F2、4F3不同,宽度方向中央部被切掉预定的宽度量。罩片4F由于具有宽度方向中央部被切掉的线状橡胶4F4、4F5,因此不会阻碍因吸收体8吸水而引起的膨胀,对穿戴者的下腹部赋予适度的紧贴感。对于罩片4R,也与罩片4F同样,宽度方向中央部被切掉预定的宽度量的线状橡胶4R4、4R5粘接于罩片4R,从而对穿戴者的下腹部赋予适度的紧贴感。Further, the linear rubbers 4F4 and 4F5 (an example of the "first elastic member" referred to in this application) are adhered to the cover sheet 4F in an extended state, and the linear rubbers 4R4 and 4R5 are adhered to the cover in an extended state Sheet 4R. The linear rubbers 4F4 and 4F5 are elastic members provided in the region of the cover sheet 4F on the crotch region 1B side with respect to the linear rubber 4F3. In the diaper 1, the belly gathers 3T are formed on the crotch region 1B side rather than the waist gathers 3R by the linear rubbers 4F4, 4F5, 4R4, and 4R5. However, unlike the linear rubbers 4F2 and 4F3 extending from the left end to the right end of the cover sheet 4F, the linear rubbers 4F4 and 4F5 are cut off by a predetermined width in the widthwise central portion. Since the cover sheet 4F has the linear rubbers 4F4 and 4F5 whose widthwise central portions are cut off, the cover sheet 4F does not inhibit the expansion due to the absorption of water by the absorber 8, and provides an appropriate fit to the lower abdomen of the wearer. As for the cover sheet 4R, like the cover sheet 4F, the linear rubbers 4R4 and 4R5 whose widthwise central portions are cut by a predetermined width are adhered to the cover sheet 4R, thereby imparting an appropriate fit to the lower abdomen of the wearer. .

另外,如图3B所示,吸收体8具有在尿布1的长度方向上延伸的一对槽8SL、8SR。一对槽8SL、8SR在厚度方向上贯通吸收体8,以下裆区域1B为中心延伸。槽8SL、8SR具有彼此相同的长度及宽度,在尿布1的长度方向上配置于相同的位置。另外,槽8SL、8SR相对于尿布1的宽度方向的中心对称地配置,相互平行地形成。穿戴者排出的尿被向一对槽8SL、8SR内导入,被向吸收体8的整体扩散。Moreover, as shown to FIG. 3B, the absorber 8 has a pair of groove|channel 8SL and 8SR extended in the longitudinal direction of the diapar 1. The pair of grooves 8SL and 8SR penetrates the absorber 8 in the thickness direction, and extends around the crotch region 1B. The grooves 8SL and 8SR have the same length and width, and are arranged at the same position in the longitudinal direction of the diaper 1 . Moreover, grooves 8SL and 8SR are symmetrically arrange|positioned with respect to the center of the width direction of the diapar 1, and are formed in parallel with each other. The urine discharged by the wearer is introduced into the pair of grooves 8SL and 8SR, and is diffused over the entire absorber 8 .

另外,线状橡胶4F4、4F5以伸长状态配置于一对槽8SL、8SR的前身区域1F侧的端部(腹侧端部)的尿布1的宽度方向的外侧。在此,本实施方式的尿布1适合用于男性及女性的婴幼儿。图3B所示的椭圆状的虚线所示的区域40成为与穿戴者的尿道口对应的尿道口对应区域(以下,称为“尿道口对应区域40”)。尿道口对应区域40是指在尿布1的通常的穿戴状态下在厚度方向上同穿戴者的尿道口与顶片9进行抵接的位置重叠的区域。尿道口对应区域40配置于尿布1的前身区域1F侧,一对槽8SL、8SR配置于比尿道口对应区域40靠下裆区域1B侧的位置。另外,尿道口对应区域40与尿布1的腹侧部相邻。在此,腹侧部是腰部褶裥3R的前身区域1F侧,是线状橡胶4F2、4F3的配置区域。换言之,尿道口对应区域40与前身区域1F侧的腰部褶裥3R相邻。Moreover, the linear rubbers 4F4 and 4F5 are arrange|positioned in the outer side of the width direction of the diaper 1 in the edge part (abdominal side edge part) of the front body region 1F side of a pair of groove|channel 8SL and 8SR in the extended state. Here, the diaper 1 of the present embodiment is suitable for male and female infants. The region 40 shown by the elliptical broken line shown in FIG. 3B is the urethral orifice corresponding region (hereinafter, referred to as "urethral orifice corresponding region 40") corresponding to the urethral orifice of the wearer. The urethral orifice corresponding region 40 refers to a region that overlaps the position where the wearer's urethral orifice and the top sheet 9 abut in the thickness direction in the normal wearing state of the diaper 1 . The urethra corresponding region 40 is arranged on the front body region 1F side of the diaper 1 , and the pair of grooves 8SL and 8SR are arranged on the crotch region 1B side rather than the urethra corresponding region 40 . In addition, the urethral orifice corresponding region 40 is adjacent to the ventral portion of the diaper 1 . Here, the ventral portion is the front body region 1F side of the waist gather 3R, and is an arrangement region of the linear rubbers 4F2 and 4F3. In other words, the urethral orifice corresponding region 40 is adjacent to the waist gather 3R on the front body region 1F side.

在尿布1的穿戴状态下,比一对槽8SL、8SR靠宽度方向的外侧由线状橡胶4F5向皮肤面方向压靠,一对槽8SL、8SR之间不被向皮肤面方向压靠,在顶片9与皮肤面之间形成空间。这是因为,线状橡胶4F5向宽度方向的外侧拉拽尿布1的力由槽8SL、8SR阻碍,一对槽8SL、8SR之间与一对槽8SL、8SR的宽度方向的外侧相比容易从皮肤面离开。尿布1能够将穿戴时排出到尿道口对应区域40的尿暂且积存在该空间内。并且,尿布1能够将积存于空间内的尿向槽8SL、8SR逐渐引导,能够使尿沿着槽8SL、8SR向吸收体8的整体扩散。由此,本实施方式的尿布1通过抑制尿从横侧泄漏的横向泄漏、尿从腹侧泄漏的腹部泄漏,从而能够抑制尿泄漏。In the wearing state of the diaper 1, the outer side in the width direction than the pair of grooves 8SL and 8SR is pressed toward the skin surface by the linear rubber 4F5, and the pair of grooves 8SL and 8SR is not pressed toward the skin surface. A space is formed between the topsheet 9 and the skin surface. This is because the force of the linear rubber 4F5 pulling the diaper 1 to the outer side in the width direction is blocked by the grooves 8SL and 8SR, and the distance between the pair of grooves 8SL and 8SR is easier than the outer side of the pair of grooves 8SL and 8SR in the width direction. skin side away. The diaper 1 can temporarily store the urine discharged to the urethral opening corresponding region 40 in the space. Furthermore, the diaper 1 can gradually guide the urine accumulated in the space to the grooves 8SL and 8SR, and can diffuse the urine to the entire absorber 8 along the grooves 8SL and 8SR. Thereby, the diaper 1 of this embodiment can suppress urine leakage by suppressing the lateral leakage in which urine leaks from the lateral side, and the abdominal leakage in which urine leaks from the ventral side.

而且,线状橡胶4R5(本申请中所说的“第2伸缩性构件”的一例)以伸长状态配置于一对槽8SL、8SR的后身区域1R侧的端部(背侧端部)的尿布1的宽度方向的外侧。由图3B所示的椭圆状的虚线图示的区域30成为与穿戴者的肛门对应的肛门对应区域(以下,称为“肛门对应区域30”)。肛门对应区域30是在尿布1的通常的穿戴状态下在厚度方向上同穿戴者的肛门与顶片9进行抵接的位置重叠的区域。肛门对应区域30配置于尿布1的后身区域1R侧,一对槽8SL、8SR配置于比肛门对应区域30靠下裆区域1B侧的位置。另外,肛门对应区域30与尿布1的背侧部相邻。在此,背侧部是腰部褶裥3R的后身区域1R侧,是线状橡胶4R2、4R3的配置区域。换言之,肛门对应区域30与后身区域1R侧的腰部褶裥3R相邻。Furthermore, the linear rubber 4R5 (an example of the "second elastic member" referred to in this application) is arranged in an extended state at the end (back end) of the pair of grooves 8SL and 8SR on the side of the rear body region 1R. The outer side of the diaper 1 in the width direction. The region 30 shown by the ellipse-shaped dotted line shown in FIG. 3B is an anus-corresponding region (hereinafter, referred to as "anus-corresponding region 30") corresponding to the wearer's anus. The anus corresponding region 30 is a region that overlaps with the position where the wearer's anus and the top sheet 9 abut in the thickness direction in the normal wearing state of the diaper 1 . The anus-corresponding region 30 is arranged on the back body region 1R side of the diaper 1 , and the pair of grooves 8SL and 8SR are arranged on the crotch region 1B side rather than the anus-corresponding region 30 . Moreover, the anus corresponding area|region 30 is adjacent to the back side part of the diaper 1. As shown in FIG. Here, the back part is the back body region 1R side of the waist gather 3R, and is an arrangement region of the linear rubbers 4R2 and 4R3. In other words, the anus corresponding region 30 is adjacent to the waist gather 3R on the back body region 1R side.

在尿布1的穿戴状态下,比一对槽8SL、8SR靠宽度方向的外侧由线状橡胶4R5向皮肤面方向压靠,一对槽8SL、8SR之间不被向皮肤面方向压靠,在顶片9与皮肤面之间形成空间。这是因为,线状橡胶4R5向宽度方向的外侧拉拽尿布1的力由槽8SL、8SR阻碍,一对槽8SL、8SR之间与一对槽8SL、8SR的宽度方向的外侧相比容易从皮肤面离开。尿布1能够在穿戴时将排出到肛门对应区域30的粪便保持在该空间内。由此,本实施方式的尿布1能够保持粪便。In the wearing state of the diaper 1, the outer side in the width direction than the pair of grooves 8SL and 8SR is pressed toward the skin surface by the linear rubber 4R5, and the pair of grooves 8SL and 8SR is not pressed toward the skin surface. A space is formed between the topsheet 9 and the skin surface. This is because the force of the linear rubber 4R5 pulling the diaper 1 to the outer side in the width direction is blocked by the grooves 8SL and 8SR, and the distance between the pair of grooves 8SL and 8SR is easier than the outer side of the pair of grooves 8SL and 8SR in the width direction. skin side away. The diaper 1 can hold the feces discharged to the anus-corresponding region 30 in this space when worn. Thereby, the diaper 1 of this embodiment can hold excrement.

另外,在图3B中,单点划线CL是槽8SL的中心线,单点划线CR是槽8SR的中心线,槽8SL、8SR各自的中心线彼此的间隔是W。间隔W设定为20mm以上且50mm以下,以便考虑婴幼儿的身体的大小而形成穿戴状态下积存尿的空间和/或保持粪便的空间。由此,形成与婴幼儿对应的积存尿的空间和/或保持粪便的空间。另外,由于槽8SL、8SR设置于比尿道口对应区域40、肛门对应区域30靠下裆区域1B侧的位置,因此槽8SL、8SR经由顶片9也难以与尿道口和/或臀部抵接。由此,尿布1能够防止由槽8SL、8SR对尿道口和/或臀部造成刺激,防止产生尿道口附近和/或臀部的皮肤问题。3B, the one-dot chain line CL is the center line of the groove 8SL, the one-dot chain line CR is the center line of the groove 8SR, and the distance between the center lines of the grooves 8SL and 8SR is W. The interval W is set to 20 mm or more and 50 mm or less so as to form a space for storing urine and/or a space for holding feces in the wearing state in consideration of the body size of the infant. Thereby, a space for storing urine and/or a space for holding feces is formed corresponding to the infant. In addition, since the grooves 8SL and 8SR are provided at a position closer to the crotch region 1B than the urethral orifice corresponding region 40 and the anus corresponding region 30, the grooves 8SL and 8SR are also difficult to abut against the urethral orifice and/or buttocks via the top sheet 9. Thereby, the diaper 1 can prevent the urethra orifice and/or buttocks from being irritated by the grooves 8SL and 8SR, and can prevent the occurrence of skin problems in the vicinity of the urethra orifice and/or the buttocks.

此外,优选的是,一对槽8SL、8SR的前身区域1F侧的端部比尿道口对应区域40靠下裆区域1B侧,一对槽8SL、8SR的后身区域1R侧的端部比图3B所示的与穿戴者的肛门对应的肛门对应区域30靠下裆区域1B侧。尿布1防止由槽8SL、8SR对尿道口和/或肛门造成刺激,能够防止产生尿道口附近和/或肛门的皮肤问题。In addition, it is preferable that the end of the pair of grooves 8SL and 8SR on the front body region 1F side is closer to the crotch region 1B than the urethral orifice corresponding region 40, and the end of the pair of grooves 8SL and 8SR on the back body region 1R side is preferably The anus corresponding region 30 shown in 3B, which corresponds to the wearer's anus, is on the side of the crotch region 1B. The diaper 1 prevents the urethral opening and/or the anus from being irritated by the grooves 8SL and 8SR, and can prevent the occurrence of skin problems near the urethral opening and/or the anus.

在此,对将尿布1以将其长度方向的端部彼此重叠的方式对折了的情况下的从长度方向的中央起一对槽8SL、8SR的腹侧端部的长度进行规定。图3B的双点划线FL是将尿布1以将其长度方向的端部彼此重叠的方式对折了的情况下的折线,表示尿布1的长度方向的中央。在将尿布1以双点划线FL对折了的情况下,在从尿布1的长度方向的中央(双点划线FL)起一对槽8SL、8SR的腹侧端部的长度(图3B中的L1)处于90mm以上且100mm以下的范围内的情况下,尿布1适合用于体重处于5kg以上且13kg以下的范围内的婴幼儿。另外,在将尿布1以双点划线FL对折了的情况下,在从尿布1的长度方向的中央(双点划线FL)起一对槽8SL、8SR的腹侧端部的长度(L1)处于85mm以上且95mm以下的范围内的情况下,尿布1适合用于体重处于8kg以上且15kg以下的范围内的婴幼儿。另外,在将尿布1以双点划线FL对折了的情况下,在从尿布1的长度方向的中央(双点划线FL)起一对槽8SL、8SR的腹侧端部的长度(L1)处于110mm以上120mm以下的范围内的情况下,尿布1适合用于体重处于11kg以上且23kg以下的范围内的婴幼儿。另外,在将尿布1以双点划线FL对折了的情况下,在从尿布1的长度方向的中央(双点划线FL)起一对槽8SL、8SR的腹侧端部的长度(L1)处于100mm以上且110mm以下的范围内的情况下,尿布1适合用于体重处于12kg以上且29kg以下的范围内的婴幼儿。Here, the length of the abdominal edge part of a pair of groove|channels 8SL and 8SR is prescribed|regulated from the center of the longitudinal direction when the diapar 1 is folded so that the edge parts of the longitudinal direction may overlap each other. The two-dot chain line FL of FIG. 3B is a folding line when the diaper 1 is folded in half so that the ends in the longitudinal direction of the diaper 1 are overlapped with each other, and shows the center of the longitudinal direction of the diaper 1 . When the diaper 1 is folded in half by the dashed-two dotted line FL, the length of the ventral end of the pair of grooves 8SL and 8SR from the center in the longitudinal direction of the diaper 1 (the dashed-two dotted line FL) (in FIG. 3B ) When L1) is in the range of 90 mm or more and 100 mm or less, the diaper 1 is suitable for infants and young children whose weight is in the range of 5 kg or more and 13 kg or less. In addition, when the diaper 1 is folded in half by the dashed-two dotted line FL, the length (L1) of the ventral end of the pair of grooves 8SL and 8SR from the center (the dashed-two dotted line FL) in the longitudinal direction of the diaper 1 ) in the range of 85 mm or more and 95 mm or less, the diaper 1 is suitable for infants and young children whose weight is in the range of 8 kg or more and 15 kg or less. In addition, when the diaper 1 is folded in half by the dashed-two dotted line FL, the length (L1) of the ventral end of the pair of grooves 8SL and 8SR from the center (the dashed-two dotted line FL) in the longitudinal direction of the diaper 1 ) in the range of 110 mm or more and 120 mm or less, the diaper 1 is suitable for infants and young children whose weight is in the range of 11 kg or more and 23 kg or less. In addition, when the diaper 1 is folded in half by the dashed-two dotted line FL, the length (L1) of the ventral end of the pair of grooves 8SL and 8SR from the center (the dashed-two dotted line FL) in the longitudinal direction of the diaper 1 ) in the range of 100 mm or more and 110 mm or less, the diaper 1 is suitable for infants and young children whose weight is in the range of 12 kg or more and 29 kg or less.

此外,优选在尿道口对应区域40不配置线状橡胶等伸缩性构件(弹性构件)。通过在尿道口对应区域40不配置伸缩性构件,能够防止妨碍形成积存尿的空间。In addition, it is preferable that a stretchable member (elastic member) such as a linear rubber or the like is not arranged in the urethral orifice corresponding region 40 . By not arranging a stretchable member in the urethral orifice corresponding region 40, it is possible to prevent the formation of a space for storing urine from being hindered.

另外,积存尿的空间通过由尿布1从在图3B中用粗虚线呈矩形状地图示的假想的立起线L3向非皮肤面侧呈拱顶状鼓起而形成。以下,对立起线L3的位置进行说明。Moreover, the space for storing urine is formed by the diaper 1 bulging in a dome shape toward the non-skin surface side from an imaginary rising line L3 shown in a rectangular shape with a thick broken line in FIG. 3B . Hereinafter, the position of the rising line L3 will be described.

腹部褶裥3T形成于尿道口对应区域40的宽度方向的两侧且比一对槽8SL、8SR的腹侧(前身区域1F侧)的延伸线上靠宽度方向的外侧的位置。此外,前身区域1F侧的腹部褶裥3T是线状橡胶4F4、4F5的配置区域,线状橡胶4F4、4F5配置于尿道口对应区域40的宽度方向的两侧且比一对槽8SL、8SR的腹侧(前身区域1F侧)的延伸线上靠宽度方向的外侧的位置。这是因为,在尿布1的穿戴状态下,需要至少包括尿道口对应区域40在内地形成积存尿的空间,但另一方面,若该空间过大,则尿有可能流出到槽8SL、8SR以外的区域,因此需要形成能够贮存婴幼儿的1次排尿量的程度的大小的空间。因此,在本实施方式中,不是通过将尿道口对应区域40向皮肤面方向压靠,而是通过在比一对槽8SL、8SR的延伸线上靠宽度方向的外侧的位置利用线状橡胶4F4、4F5的收缩力将腹部褶裥3T的宽度方向端部向皮肤面方向压靠,从而将立起线L3的宽度方向端部规定在腹部褶裥3T的宽度方向端部。由此,尿布1能够防止该空间在宽度方向上过度地扩展。The abdominal gathers 3T are formed on both sides in the width direction of the urethral orifice corresponding region 40 and on the outer side in the width direction with respect to the extension line of the ventral side (front body region 1F side) of the pair of grooves 8SL and 8SR. In addition, the abdomen gather 3T on the side of the front body region 1F is an arrangement region of the linear rubbers 4F4 and 4F5, which are arranged on both sides in the width direction of the urethral orifice corresponding region 40 compared with the pair of grooves 8SL and 8SR. The position on the outer side in the width direction on the extension line of the ventral side (front body region 1F side). This is because, in the wearing state of the diaper 1, a space for storing urine needs to be formed in the interior including at least the urethral orifice corresponding region 40. On the other hand, if the space is too large, the urine may flow out of the grooves 8SL and 8SR. Therefore, it is necessary to form a space of a size that can store the urination volume of an infant. Therefore, in this embodiment, instead of pressing the urethral orifice corresponding region 40 in the direction of the skin surface, the linear rubber 4F4 is used at a position outside the extension line of the pair of grooves 8SL and 8SR in the width direction. The contraction force of 4F5 presses the widthwise end of the abdominal gathers 3T against the skin surface direction, and defines the widthwise end of the rising line L3 at the widthwise end of the abdominal gather 3T. Thereby, the diaper 1 can prevent this space from spreading too much in the width direction.

另外,若考虑婴幼儿的尿道口的位置等,则尿道口对应区域40的在尿布1的长度方向上的长度(图3B中的L2)优选为50mm。另外,如图3B所示,配置于尿道口对应区域40的宽度方向的外侧的线状橡胶4F4、4F5以比配置于一对槽8SL、8SR的腹侧端部的宽度方向的外侧的线状橡胶4F5短的间隔配置。因此,腹部褶裥3T的在尿道口对应区域40的宽度方向的外侧的伸缩力比在一对槽8SL、8SR的腹侧端部的宽度方向的外侧的伸缩力大。这是因为,由于槽8SL、8SR的腹侧端部规定了空间形成的下裆区域1B侧的立起线L3,因此只要在槽8SL、8SR的宽度方向外侧以必要充分的力将尿布1向皮肤方向压靠即可,但若尿道口对应区域40的宽度方向外侧为与槽8SL、8SR的宽度方向外侧相同程度或比槽8SL、8SR的宽度方向外侧弱的伸缩力,则会导致空间在宽度方向上扩展,无法维持能够贮存婴幼儿的1次排尿量的大小的空间。对于本实施方式的尿布1,在腹部褶裥3T中,通过使尿道口对应区域40的宽度方向的外侧的伸缩力比一对槽8SL、8SR的腹侧端部的宽度方向的外侧的伸缩力大,从而能够防止空间变得过大,能够适当地维持积存尿的空间。In addition, in consideration of the position of the urethral orifice of infants and the like, the length (L2 in FIG. 3B ) of the urethral orifice corresponding region 40 in the longitudinal direction of the diaper 1 is preferably 50 mm. In addition, as shown in FIG. 3B , the linear rubbers 4F4 and 4F5 arranged on the outer side in the width direction of the urethral orifice corresponding region 40 are more linear than the linear rubbers 4F4 and 4F5 arranged on the outer side in the width direction of the ventral ends of the pair of grooves 8SL and 8SR. Rubber 4F5 short interval configuration. Therefore, the expansion-contraction force on the outer side in the width direction of the urethra orifice corresponding region 40 of the abdominal gather 3T is larger than the expansion-contraction force on the outer side in the width direction of the ventral end portions of the pair of grooves 8SL and 8SR. This is because the abdominal end portions of the grooves 8SL and 8SR define the rising line L3 on the side of the crotch region 1B formed by the space, so that the diaper 1 can be pushed against the outer side in the width direction of the grooves 8SL and 8SR with a necessary and sufficient force. It is sufficient to press against the skin in the direction of the skin. However, if the outer side in the width direction of the urethral orifice corresponding region 40 is the same as or weaker than the outer side in the width direction of the grooves 8SL and 8SR, the space will be larger than the outer side in the width direction of the grooves 8SL and 8SR. It expands in the width direction, and cannot maintain a space of a size that can store the urination volume of an infant. In the diaper 1 of the present embodiment, in the abdomen gather 3T, the expansion and contraction force of the outer side in the width direction of the urethral orifice corresponding region 40 is made larger than the expansion and contraction force of the outer side in the width direction of the abdominal end portions of the pair of grooves 8SL and 8SR. It is possible to prevent the space from becoming too large and maintain the space for storing urine appropriately.

另外,在尿道口对应区域40的腹侧设置有腰部褶裥3R。腰部褶裥3R通过将尿布1向皮肤面方向压靠,从而规定积存尿的空间的腹侧的立起线L3。即,腰部褶裥3R的下裆区域1B侧(下裆区域1B侧的线状橡胶4F3)规定空间的腹侧的立起线L3。本实施方式的尿布1能够利用腰部褶裥3R防止空间向腹侧变得过大,能够适当地维持积存尿的空间。In addition, waist gathers 3R are provided on the ventral side of the urethral orifice corresponding region 40 . The waist gather 3R defines the raising line L3 on the ventral side of the space where the urine is stored by pressing the diaper 1 in the direction of the skin surface. That is, the waist gather 3R on the side of the crotch region 1B (the linear rubber 4F3 on the side of the crotch region 1B) defines the rising line L3 on the abdominal side of the space. The diaper 1 of this embodiment can prevent the space from becoming too large to the ventral side by the waist gathers 3R, and can maintain the space for storing urine appropriately.

另外,如图3B所示,在平面观察尿布1的情况下,吸收体8的长度方向端部位于垫罩片6的腹侧端部(前身区域1F侧的端部)的内侧,形成腰部褶裥3R的线状橡胶4F3的一部分与吸收体8重叠。由此,尿布1并不将垫罩片6、吸收体8的腹侧端部作为空间的腹侧的立起线L3,而能够将腰部褶裥3R的下裆区域1B侧的端部规定为空间的腹侧的立起线L3。假设将垫罩片6、吸收体8的腹侧端部作为空间的物理上的立起线,则由于该物理上的立起线与尿道口及其周边的皮肤抵接,而可能产生皮肤问题等问题。对此,本实施方式的尿布1能够将腰部褶裥3R的下裆区域1B侧规定为空间的腹侧的假想的立起线L3,因此,能够形成积存尿的空间,并且能够防止产生由于物理上的立起线与尿道口及其周边的皮肤抵接而可能产生的皮肤问题等问题。In addition, as shown in FIG. 3B , when the diaper 1 is viewed in plan, the longitudinal direction end of the absorber 8 is positioned inside the abdominal end (end on the front body region 1F side) of the pad cover sheet 6 , and waist gathers are formed. A part of the linear rubber 4F3 of the gather 3R overlaps with the absorber 8 . Thereby, the diaper 1 can define the edge part of the waist gather 3R on the crotch region 1B side without making the abdominal side edge part of the pad cover sheet 6 and the absorber 8 the rise line L3 on the abdominal side of the space. Rising line L3 on the ventral side of the space. Assuming that the ventral end of the cover sheet 6 and the absorber 8 is used as a physical rising line of space, the physical rising line comes into contact with the skin around the urethra orifice, which may cause skin problems. And other issues. On the other hand, in the diaper 1 of the present embodiment, the crotch region 1B side of the waist gather 3R can be defined as the virtual rising line L3 on the abdominal side of the space, so that a space for storing urine can be formed, and the occurrence of physical problems can be prevented. There may be problems such as skin problems caused by the erection line on the urethra and the surrounding skin contacting the urethra.

另外,吸收体8的与腰部褶裥3R重叠的重叠部8A的宽度方向的长度短于比该重叠部8A靠下裆侧的部位8B的宽度方向的长度。在此,重叠部8A是在吸收体8中与线状橡胶4F3重叠的部位,下裆侧的部位8B是比重叠部8A靠下裆区域1B侧的部位。通过采用这样的形状的吸收体8,从而重叠部8A的宽度方向的端部向宽度方向内侧收缩,容易形成积存尿的空间。Moreover, the width direction length of the overlapping part 8A which overlaps with 3R of waist gathers of the absorber 8 is shorter than the width direction length of the site|part 8B on the crotch side rather than this overlapping part 8A. Here, the overlapping portion 8A is a portion overlapping the linear rubber 4F3 in the absorber 8, and the crotch side portion 8B is a portion closer to the crotch region 1B than the overlapping portion 8A. By adopting the absorber 8 of such a shape, the widthwise end portion of the overlapping portion 8A shrinks inwardly in the widthwise direction, and it becomes easy to form a space for storing urine.

另外,如图3A和图3B所示,在平面观察尿布1的情况下,线状橡胶4F4、4F5的宽度方向的端部与吸收体8重叠,与吸收体8直接或间接地粘接。在此,该端部与吸收体8直接地粘接是指,该端部与吸收体8直接地接合,该端部与吸收体8间接地粘接是指,该端部与吸收体8经由内罩片5F、垫罩片6、背片7接合。在本实施方式中,该端部与吸收体8间接地粘接。假设在比吸收体8靠宽度方向外侧的位置设置有线状橡胶4F4、4F5,吸收体8与线状橡胶4F4、4F5不直接或间接地粘接,则由线状橡胶4F4、4F5产生的伸缩力会在比吸收体8靠宽度方向外侧的位置发挥,无法使该收缩力有助于形成积存尿的空间。在本实施方式的尿布1中,由于线状橡胶4F4、4F5的宽度方向端部与吸收体8间接地粘接,因此能够使由线状橡胶4F4、4F5产生的伸缩力有助于空间形成。此外,由线状橡胶4F4、4F5产生的伸缩力通过在尿布1的穿戴状态下与尿布1的非穿戴状态相比向宽度方向的外侧拉拽腹部褶裥3T而进行发挥。3A and 3B , when the diaper 1 is viewed in plan, the ends in the width direction of the linear rubbers 4F4 and 4F5 overlap with the absorber 8 and are directly or indirectly bonded to the absorber 8 . Here, the end portion and the absorber 8 are directly bonded means that the end portion is directly bonded to the absorber 8 , and the end portion is indirectly bonded to the absorber 8 means that the end portion and the absorber 8 pass through The inner cover sheet 5F, the cushion cover sheet 6 and the back sheet 7 are joined. In this embodiment, the end portion is indirectly bonded to the absorber 8 . Assuming that the linear rubbers 4F4 and 4F5 are provided on the outer side of the absorber 8 in the width direction, and the absorber 8 and the linear rubbers 4F4 and 4F5 are not directly or indirectly bonded, the stretching force generated by the linear rubbers 4F4 and 4F5 It is exerted at a position outside the absorber 8 in the width direction, and the contraction force cannot be used to form a space for storing urine. In the diaper 1 of this embodiment, since the width direction end parts of the linear rubbers 4F4 and 4F5 are indirectly bonded to the absorber 8, the expansion and contraction force generated by the linear rubbers 4F4 and 4F5 can contribute to space formation. Moreover, the expansion-contraction force by the linear rubbers 4F4 and 4F5 is exhibited by pulling the abdomen gathers 3T to the outer side in the width direction in the wearing state of the diaper 1 compared with the non-wearing state of the diaper 1 .

在上述实施方式的尿布1中,作为与穿戴者的皮肤抵接的顶片9(外顶片9A),使用弱酸性的片。在此,例如,在由于穿戴者的动作而对吸收体8施加了压力时,有时会发生由吸收体8保持着的从穿戴者排泄出的液体被从吸收体8挤出而返回到穿戴者的皮肤这样的回流。但是,由于顶片9为弱酸性,因此即使发生回流,也能够用顶片9的pH调整成分来中和该液体中含有的氨等碱成分。因此,能够将穿戴者的皮肤从弱酸性维持为中性,能够抑制产生皮肤问题。In the diaper 1 of the above-described embodiment, a weakly acidic sheet is used as the top sheet 9 (outer top sheet 9A) that is in contact with the wearer's skin. Here, for example, when pressure is applied to the absorber 8 due to the action of the wearer, the liquid held by the absorber 8 and excreted from the wearer may be squeezed out of the absorber 8 and returned to the wearer. of the skin such a reflux. However, since the top sheet 9 is weakly acidic, even if reflux occurs, alkali components such as ammonia contained in the liquid can be neutralized by the pH adjusting component of the top sheet 9 . Therefore, the wearer's skin can be maintained from weakly acidic to neutral, and the occurrence of skin problems can be suppressed.

但是,本申请发明人发现:在顶片9处于被回流的液体等润湿的状态的情况下,由于顶片9被该液体覆盖,而有时无法充分地发挥顶片9的弱酸性的性质。However, the inventors of the present application have found that when the topsheet 9 is in a wetted state with a refluxed liquid or the like, because the topsheet 9 is covered by the liquid, sometimes the weakly acidic properties of the topsheet 9 cannot be fully exerted.

本申请发明人测定了赋予弱酸性的性质的本申请的顶片9(外顶片9A)及未赋予弱酸性的性质的通常的顶片的pH。在pH的测定中,使用了ハンナインスツルメント制造的pH计(主体:HI99181N,电极:HI1414D/50)。并且,将本申请的顶片9及通常的顶片分别放置在聚丙烯(PP)的方盘(日文:バット)上,在使电极与片接触了时读取显示于主体的数值。此时,本申请的顶片9例如显示出pH为5.8的弱酸性,通常的顶片例如显示出pH为6.8的中性。而且,为了确认是否即使在片润湿的状态下也能够维持该片的性质,用离子交换水分别润湿本申请的顶片9及通常的顶片,测定了各片的pH。此时,本申请的顶片9及通常的顶片均显示出pH为7.0±0.1、即离子交换水的pH。由此可知,在片润湿的状态下,覆盖该片的液体的pH的影响大,无法充分地发挥该片的性质。The inventors of the present application measured the pH of the topsheet 9 (outer topsheet 9A) of the present application to which the weakly acidic property was imparted and the normal topsheet to which the weakly acidic property was not imparted. For the measurement of pH, a pH meter (main body: HI99181N, electrode: HI1414D/50) manufactured by Hannainstar was used. Then, the top sheet 9 of the present application and a normal top sheet were placed on a polypropylene (PP) square plate (Japanese: バット), respectively, and the numerical value displayed on the main body was read when the electrodes were brought into contact with the sheet. At this time, the top sheet 9 of the present application exhibits weak acidity of pH 5.8, for example, and a normal top sheet exhibits neutrality of pH 6.8, for example. Furthermore, in order to confirm whether the properties of the sheet can be maintained even when the sheet is wet, the top sheet 9 of the present application and a normal top sheet were respectively wetted with ion-exchanged water, and the pH of each sheet was measured. At this time, both the top sheet 9 of the present application and a normal top sheet showed a pH of 7.0±0.1, that is, the pH of ion-exchanged water. From this, it can be seen that in the wet state of the sheet, the pH of the liquid covering the sheet has a great influence, and the properties of the sheet cannot be sufficiently exhibited.

因此,在本实施方式的尿布1中,顶片9具有包含外顶片9A及内顶片9B的多层构造,以使得能够充分地发挥片的性质。Therefore, in the diaper 1 of this embodiment, the topsheet 9 has a multilayer structure including the outer topsheet 9A and the inner topsheet 9B so that the properties of the sheet can be sufficiently exhibited.

图6A是说明使用了图4A和图4B所示的顶片9的第1例的情况下的回流时的来自吸收体8的液体的流动的图,图6B是说明使用了图5A和图5B所示的顶片9的第2例的情况下的回流时的来自吸收体8的液体的流动的图。此外,在图6A和图6B中,为了更明确地说明顶片9的多层构造,一并示出穿戴者的皮肤SK。6A is a diagram illustrating the flow of the liquid from the absorber 8 at the time of backflow in the case where the first example of the top sheet 9 shown in FIGS. 4A and 4B is used, and FIG. 6B is a diagram illustrating the use of The figure of the flow of the liquid from the absorber 8 at the time of reflow in the case of the 2nd example of the top sheet 9 shown. In addition, in FIG. 6A and FIG. 6B, in order to demonstrate the multilayer structure of the top sheet 9 more clearly, the skin SK of a wearer is shown together.

如上所述,在图4A和图4B所示的顶片9的第1例中,外顶片9A的片面积比内顶片9B的片面积大,外顶片9A隔开间隔地在多个部位(熔接部WL)接合于内顶片9B。由此,在外顶片9A与内顶片9B之间形成有空间。也就是说,外顶片9A与内顶片9B接合的部分仅为熔接部WL。在假设外顶片9A具有与内顶片9B相同的片面积,外顶片9A仅层叠于内顶片9B的情况下,外顶片9A与内顶片9B接触的部分的面积容易变大。并且,外顶片9A与内顶片9B接触的部分成为外顶片9A与内顶片9B之间的液体回流时的流路,因此在该接触的部分的面积大的情况下,液体容易从内顶片9B传递到外顶片9A。As mentioned above, in the 1st example of the top sheet 9 shown in Figure 4A and Figure 4B, the sheet area of the outer top sheet 9A is larger than the sheet area of the inner top sheet 9B, and the outer top sheet 9A is spaced apart at a plurality of positions (Welded portion WL) is joined to the inner top sheet 9B. Thereby, a space is formed between the outer top sheet 9A and the inner top sheet 9B. That is, the portion where the outer topsheet 9A and the inner topsheet 9B are joined is only the welded portion WL. Assuming that the outer topsheet 9A has the same sheet area as the inner topsheet 9B, and the outer topsheet 9A is only stacked on the inner topsheet 9B, the area of the portion where the outer topsheet 9A contacts the inner topsheet 9B tends to increase. And, the part that the outer top sheet 9A contacts with the inner top sheet 9B becomes the flow path during the liquid backflow between the outer top sheet 9A and the inner top sheet 9B, so in the case that the area of the part of this contact is large, the liquid is easily removed from the The inner topsheet 9B is passed on to the outer topsheet 9A.

相对于此,在图4A和图4B所示的顶片9的第1例中,如图6A中箭头所示,仅外顶片9A与内顶片9B接合的部分(熔接部WL)成为液体回流时的流路,因此液体难以从内顶片9B传递到外顶片9A。因此,能够使外顶片9A不易成为被回流的液体润湿的状态。With respect to this, in the first example of the top sheet 9 shown in Figure 4A and Figure 4B, as shown by the arrow in Figure 6A, only the part (welded portion WL) where the outer top sheet 9A and the inner top sheet 9B are joined becomes liquid Since it is a flow path at the time of backflow, it is difficult for liquid to transfer from the inner topsheet 9B to the outer topsheet 9A. Therefore, the outer top sheet 9A can be made difficult to be wetted by the recirculated liquid.

另外,在图5A和图5B所示的顶片9的第2例中,内顶片9B的片面积比外顶片9A的片面积大,内顶片9B隔开间隔地在多个部位(熔接部WL)接合于外顶片9A。在该第2例中,也与第1例同样地,如图6B中箭头所示,仅外顶片9A与内顶片9B接合的部分(熔接部WL)成为液体回流时的流路,因此液体难以从内顶片9B传递到外顶片9A。因此,能够使外顶片9A不易成为被回流的液体润湿的状态。In addition, in the 2nd example of the top sheet 9 shown in Figure 5A and Figure 5B, the sheet area of the inner top sheet 9B is larger than the sheet area of the outer top sheet 9A, and the inner top sheet 9B is spaced apart in a plurality of positions ( The welded portion WL) is joined to the outer top sheet 9A. In this second example, as in the first example, as shown by the arrow in FIG. 6B , only the portion where the outer topsheet 9A and the inner topsheet 9B are joined (welded portion WL) becomes the flow path during the liquid backflow, so Liquid is difficult to transfer from the inner topsheet 9B to the outer topsheet 9A. Therefore, the outer top sheet 9A can be made difficult to be wetted by the recirculated liquid.

这样,通过图4A和图4B或图5A和图5B所示的顶片9的多层构造,能够抑制(控制)回流的液体的移动,维持外顶片9A干燥的状态。因此,能够使外顶片9A的弱酸性的性质充分地发挥。4A and 4B or FIG. 5A and 5B shown in the multi-layer structure of the topsheet 9, it is possible to suppress (control) the movement of the backflowing liquid and maintain the dry state of the outer topsheet 9A. Therefore, the weakly acidic property of the outer top sheet 9A can be sufficiently exhibited.

另外,在本实施方式的尿布1中,吸收体8具有在长度方向上延伸的槽8SL、8SR。而且,槽8SL、8SR在厚度方向上贯通吸收体8。Moreover, in the diaper 1 of this embodiment, the absorber 8 has the groove|channels 8SL and 8SR extended in the longitudinal direction. Furthermore, the grooves 8SL and 8SR penetrate the absorber 8 in the thickness direction.

图7是说明第1实施方式的尿布1中的穿戴者所排出的尿的流动的图。7 : is a figure explaining the flow of the urine excreted by the wearer in the diaper 1 of 1st Embodiment.

如图7中箭头所示,穿戴者排出的尿通过顶片9暂且积存于在吸收体8的前身区域1F侧的区域形成的积存尿的空间S1。此外,如上所述,空间S1是包括尿道口对应区域40的空间。在本实施方式中,吸收体8具有在长度方向上延伸的槽8SL、8SR,由此能够使积存于空间S1的尿经由槽8SL、8SR从前身区域1F侧的区域通过下裆区域1B侧的区域向后身区域1R侧的区域(在图7中为从右侧的区域通过中央的区域向左侧的区域)迅速地移动。由此,能够使积存于空间S1的尿向吸收体8的长度方向的整体迅速地浸入并保持,因此能够使顶片9、特别是外顶片9A迅速地成为干燥的状态。因此,能够使外顶片9A的弱酸性的性质更充分地发挥。As shown by the arrow in FIG. 7 , the urine discharged by the wearer is temporarily accumulated in the urine accumulation space S1 formed in the region on the front body region 1F side of the absorber 8 through the top sheet 9 . Further, as described above, the space S1 is a space including the urethral orifice corresponding region 40 . In the present embodiment, since the absorber 8 has the grooves 8SL and 8SR extending in the longitudinal direction, the urine accumulated in the space S1 can pass through the grooves 8SL and 8SR from the front body region 1F side through the crotch region 1B side through the grooves 8SL and 8SR. The area moves rapidly toward the area on the side of the rear body area 1R (in FIG. 7 , the area from the right side passes through the center area to the left side area). Thereby, the urine accumulated in the space S1 can be quickly infiltrated and held in the entire longitudinal direction of the absorber 8, so that the topsheet 9, especially the outer topsheet 9A can be quickly brought into a dry state. Therefore, the weakly acidic property of the outer top sheet 9A can be more fully exhibited.

而且,能够利用在长度方向上延伸的槽8SL、8SR使积存于空间S1的尿向下裆区域1B侧的区域、后身区域1R侧的区域移动,因此能够避免使尿集中地浸入吸收体8的空间S1、即尿道口对应区域40及其周边的区域并在那里保持的情形。因此,能够抑制从吸收体8的尿道口对应区域40及其周边的区域产生回流。Furthermore, since the urine accumulated in the space S1 can be moved to the region on the crotch region 1B side and the region on the back body region 1R side by the grooves 8SL and 8SR extending in the longitudinal direction, it is possible to avoid concentrated infiltration of urine into the absorber 8 The space S1, that is, the urethral orifice corresponds to the area 40 and its surrounding area and is maintained there. Therefore, it is possible to suppress the occurrence of backflow from the urethral orifice corresponding region 40 of the absorber 8 and the region around it.

而且,通过使槽8SL、8SR在厚度方向上贯通吸收体8,从而能够使积存于空间S1的尿从吸收体8的皮肤面侧的表面(在图7中为顶片9侧的表面)向非皮肤面侧的表面(在图7中为背片7侧的表面)移动。由此,能够使积存于空间S1的尿不仅向皮肤面侧的表面,还向非皮肤面侧的表面迅速地浸入并在那里保持,因此能够使外顶片9A更迅速地成为干燥的状态。因此,能够使外顶片9A的弱酸性的性质更充分地发挥。Furthermore, by making the grooves 8SL and 8SR penetrate the absorber 8 in the thickness direction, the urine accumulated in the space S1 can be directed from the surface of the absorber 8 on the skin side (the surface on the side of the top sheet 9 in FIG. 7 ) to the The surface on the non-skin surface side (the surface on the back sheet 7 side in FIG. 7 ) moves. Thereby, the urine accumulated in the space S1 can be quickly infiltrated and held not only on the surface on the skin side but also on the surface on the non-skin side, so that the outer top sheet 9A can be brought into a dry state more quickly. Therefore, the weakly acidic property of the outer top sheet 9A can be more fully exhibited.

而且,能够利用在厚度方向上贯通的槽8SL、8SR使积存于空间S1的尿从吸收体8的皮肤面侧的表面向非皮肤面侧的表面移动,因此能够避免使尿集中地浸入吸收体8的皮肤面侧并在那里保持的情形。因此,能够抑制从吸收体8的皮肤面侧的表面产生回流。Furthermore, since the urine accumulated in the space S1 can be moved from the skin-side surface of the absorber 8 to the non-skin-side surface by the grooves 8SL and 8SR penetrating in the thickness direction, it is possible to avoid concentrated infiltration of urine into the absorber. 8 is the case where the skin faces and remains there. Therefore, it is possible to suppress the occurrence of backflow from the surface of the absorber 8 on the skin side.

<第1实施方式的变形例1><Modification 1 of the first embodiment>

接着,对第1实施方式的变形例1的尿布1进行说明。图8是从本变形例的尿布1中仅提取吸收体8并用包含槽8SL的截面剖切的情况下的吸收体8的长度方向的剖视图。在本变形例中,槽8SL也可以形成为随着朝向长度方向的两端部而逐渐变浅。这样的槽8SL在利用成形鼓制作吸收体8时形成。此外,槽8SR也具有与槽8SL同样的形状。本变形例的尿布1通过将一对槽8SL、8SR形成为长度方向的两端部变浅,从而能够使尿从槽8SL、8SR的长度方向的端部向槽外流出时的流速变慢,能够抑制由于尿以较快的流速从槽8SL、8SR跑出而导致的尿泄漏。另外,在本变形例的尿布1中,即使在槽8SL、8SR的长度方向的端部与尿道口及其附近的皮肤接触的情况下,也能够减弱槽8SL、8SR向尿道口及其附近的皮肤的接触。Next, the diaper 1 of the modification 1 of 1st Embodiment is demonstrated. FIG. 8 is a cross-sectional view in the longitudinal direction of the absorber 8 when only the absorber 8 is extracted from the diaper 1 of the present modification, and the absorber 8 is cut by a cross section including the grooves 8SL. In the present modification, the grooves 8SL may be formed to gradually become shallower toward both ends in the longitudinal direction. Such grooves 8SL are formed when the absorber 8 is produced using a forming drum. In addition, the groove 8SR also has the same shape as the groove 8SL. In the diaper 1 of the present modification, by forming the pair of grooves 8SL and 8SR so that both ends in the longitudinal direction are shallow, the flow velocity when urine flows out of the grooves from the longitudinal ends of the grooves 8SL and 8SR can be reduced. Urine leakage due to urine running out of the grooves 8SL and 8SR at a relatively fast flow rate can be suppressed. In addition, in the diaper 1 of the present modification, even when the longitudinal ends of the grooves 8SL and 8SR are in contact with the skin in the urethral orifice and its vicinity, it is possible to reduce the force of the grooves 8SL and 8SR to the urethral orifice and its vicinity. skin contact.

<第1实施方式的变形例2><Modification 2 of the first embodiment>

接着,对第1实施方式的变形例2的尿布1进行说明。图9A和图9B是示意性地示出将本变形例的尿布1展开并伸长的状态的图。在本变形例的尿布1中,吸收体8具有形成在一对槽8SL、8SR之间并在尿布1的长度方向上延伸的槽8SM。槽8SM以与槽8SL、8SR相同的形状、相同的长度平行地形成。另外,槽8SM以长度方向上的位置与槽8SL、8SR的长度方向上的位置相同的方式形成。在本变形例的尿布1中,通过吸收体8具有槽8SM,从而吸收体8容易沿着槽8SM折弯,因此在穿戴状态下,容易形成积存尿的空间。Next, the diaper 1 of the modification 2 of 1st Embodiment is demonstrated. 9A and 9B are diagrams schematically showing a state in which the diaper 1 of the present modification is unfolded and stretched. In the diaper 1 of this modification, the absorber 8 has the groove|channel 8SM formed between a pair of groove|channel 8SL and 8SR, and extending in the longitudinal direction of the diaper 1. The groove 8SM is formed in parallel with the same shape and the same length as the grooves 8SL and 8SR. In addition, groove 8SM is formed so that the position in the longitudinal direction of grooves 8SL and 8SR is the same as that of grooves 8SL and 8SR. In the diaper 1 of the present modification, since the absorber 8 has the grooves 8SM, the absorber 8 is easily folded along the grooves 8SM, and therefore, in the wearing state, a space for storing urine is easily formed.

<第2实施方式><Second Embodiment>

接着,对第2实施方式进行说明。在上述第1实施方式的尿布1中,槽8SL、8SR在厚度方向上贯通吸收体8,但本实用新型不限于此。例如,槽8SL、8SR也可以形成为非贯通的凹状。Next, the second embodiment will be described. In the diaper 1 of the said 1st Embodiment, although the groove|channel 8SL and 8SR penetrates the absorber 8 in the thickness direction, this invention is not limited to this. For example, the grooves 8SL and 8SR may be formed in a non-penetrating concave shape.

图10A和图10B是示意性地示出将第2实施方式的尿布1展开并伸长的状态的图。图10A示意性地示出从左侧观察展开并伸长的状态的尿布1时的内部构造。图10B示意性地示出展开并伸长的状态的尿布1的平面图。本实施方式的尿布1除了吸收体的结构以外,具有与第1实施方式的尿布1相同的结构。因此,在本实施方式的尿布1中,对与第1实施方式的尿布1相同的构成要素标注相同的附图标记,并省略其说明。10A and 10B are diagrams schematically showing a state in which the diaper 1 of the second embodiment is unfolded and extended. Fig. 10A schematically shows the internal structure of the diaper 1 in a state of being unfolded and stretched when viewed from the left side. Fig. 10B schematically shows a plan view of the diaper 1 in a state of being unfolded and stretched. The diaper 1 of this embodiment has the same structure as the diaper 1 of 1st Embodiment except for the structure of an absorber. Therefore, in the diaper 1 of this embodiment, the same code|symbol is attached|subjected to the same component as the diaper 1 of 1st Embodiment, and the description is abbreviate|omitted.

如图10A和图10B所示,在本实施方式的尿布1中,吸收体8具有在尿布1的长度方向上延伸的一对槽8TL、8TR。一对槽8TL、8TR具有从吸收体8的皮肤面侧的表面在厚度方向上向非皮肤面侧凹陷的凹状,以下裆区域1B为中心延伸。槽8TL、8TR具有彼此相同的长度、宽度及深度,在尿布1的长度方向上配置于相同的位置。另外,槽8TL、8TR相对于尿布1的宽度方向的中心对称地配置,相互平行地形成。另外,槽8TL、8TR各自的中心线彼此的间隔W及从尿布1的长度方向的中央起一对槽8TL、8TR的腹部端部的长度L1设定为与第1实施方式中的槽8SL、8SR各自的中心线彼此的间隔W及从尿布1的长度方向的中央起一对槽8SL、8SR的腹部端部的长度L1相同的值。通过这样的槽8TL、8TR的结构及配置,在本实施方式的尿布1中,也与第1实施方式的尿布1同样地,在吸收体8中的前身区域1F侧的区域形成积存尿的空间S1。As shown in FIGS. 10A and 10B , in the diaper 1 of the present embodiment, the absorber 8 has a pair of grooves 8TL and 8TR extending in the longitudinal direction of the diaper 1 . The pair of grooves 8TL and 8TR has a concave shape recessed in the thickness direction from the surface of the absorber 8 on the skin surface side toward the non-skin surface side, and extends around the crotch region 1B. The grooves 8TL and 8TR have mutually the same length, width, and depth, and are arranged at the same position in the longitudinal direction of the diaper 1 . Moreover, grooves 8TL and 8TR are symmetrically arrange|positioned with respect to the center of the width direction of the diapar 1, and are formed in parallel with each other. In addition, the distance W between the center lines of the grooves 8TL and 8TR and the length L1 of the abdominal end of the pair of grooves 8TL and 8TR from the center in the longitudinal direction of the diaper 1 are set to be the same as the grooves 8SL and 8TR in the first embodiment. The space|interval W of each center line of 8SR and the length L1 of the abdominal edge part of a pair of groove|channel 8SL and 8SR from the center of the longitudinal direction of the diapar 1 are the same value. By the structure and arrangement of such grooves 8TL and 8TR, in the diaper 1 of the present embodiment, similarly to the diaper 1 of the first embodiment, a space for storing urine is formed in the region on the front region 1F side in the absorber 8 S1.

另外,吸收体8具有在吸收体8的厚度方向上贯通的圆形状的贯通孔8TH。贯通孔8TH设置于尿道口对应区域40。此外,贯通孔8TH的形状不限定于圆形状。例如,贯通孔8TH的形状也可以是椭圆形状。Moreover, the absorber 8 has the circular through-hole 8TH which penetrates in the thickness direction of the absorber 8. As shown in FIG. The through hole 8TH is provided in the region 40 corresponding to the urethra orifice. In addition, the shape of the through-hole 8TH is not limited to a circular shape. For example, the shape of the through hole 8TH may be an elliptical shape.

本实施方式的尿布1具有与第1实施方式的尿布1相同的顶片9的多层构造,因此能够使外顶片9A不易成为被从吸收体8回流的液体润湿的状态。由此,能够使外顶片9A的弱酸性的性质充分地发挥。Since the diaper 1 of this embodiment has the same multilayer structure of the topsheet 9 as the diaper 1 of the first embodiment, the outer topsheet 9A can be prevented from being wetted by the liquid returning from the absorber 8 . Thereby, the weakly acidic property of 9A of outer top sheets can be fully exhibited.

另外,在本实施方式的尿布1中,吸收体8具有在长度方向上延伸的槽8TL、8TR。而且,吸收体8具有在厚度方向上贯通的贯通孔8TH。Moreover, in the diaper 1 of this embodiment, the absorber 8 has groove|channels 8TL and 8TR extended in the longitudinal direction. Moreover, the absorber 8 has the through-hole 8TH which penetrates in the thickness direction.

图11是说明第2实施方式的尿布1中的穿戴者所排出的尿的流动的图。11 : is a figure explaining the flow of the urine excreted by the wearer in the diaper 1 of 2nd Embodiment.

在本实施方式的尿布1中,通过吸收体8具有在长度方向上延伸的槽8TL、8TR,从而能够使积存于积存尿的空间S1的尿如图11中箭头所示那样经由槽8TL、8TR而在吸收体8的皮肤面侧从前身区域1F侧的区域通过下裆区域1B侧的区域向后身区域1R侧的区域(在图11中为从右侧的区域通过中央的区域向左侧的区域)迅速地移动。由此,能够使积存于空间S1的尿向吸收体8的皮肤面侧的长度方向的整体迅速地浸入并保持,因此能够使顶片9、特别是外顶片9A迅速地成为干燥的状态。因此,能够使外顶片9A的弱酸性的性质更充分地发挥。In the diaper 1 of the present embodiment, since the absorber 8 has the grooves 8TL and 8TR extending in the longitudinal direction, the urine accumulated in the urine accumulation space S1 can be passed through the grooves 8TL and 8TR as shown by the arrows in FIG. 11 . On the skin surface side of the absorber 8 , from the area on the front body area 1F side through the area on the crotch area 1B side to the area on the back body area 1R side (in FIG. 11 , from the right area through the central area to the left side area) move rapidly. Thereby, the urine accumulated in the space S1 can be quickly infiltrated and held in the entire longitudinal direction of the skin surface side of the absorber 8, so the topsheet 9, especially the outer topsheet 9A can be quickly brought into a dry state. Therefore, the weakly acidic property of the outer top sheet 9A can be more fully exhibited.

而且,能够利用槽8TL、8TR避免使尿集中地浸入吸收体8的空间S1、即尿道口对应区域40及其周边的区域并在那里保持的情形。因此,能够抑制从吸收体8的尿道口对应区域40及其周边的区域产生回流。Furthermore, the grooves 8TL and 8TR can prevent urine from infiltrating concentratedly into the space S1 of the absorber 8 , that is, the urethral orifice corresponding region 40 and its surrounding region, and holding it there. Therefore, it is possible to suppress the occurrence of backflow from the urethral orifice corresponding region 40 of the absorber 8 and the region around it.

另外,吸收体8具有在厚度方向上贯通的贯通孔8TH。由此,能够使积存于空间S1的尿从吸收体8的皮肤面侧的表面(在图11中为顶片9侧的表面)向非皮肤面侧的表面(在图11中为背片7侧的表面)移动。而且,由于贯通孔8TH设置于空间S1内的尿道口对应区域40,因此能够使积存于空间S1的尿高效地向吸收体8的非皮肤面侧的表面移动。由此,能够使积存于空间S1的尿不仅向皮肤面侧的表面,还向非皮肤面侧的表面迅速地浸入并在那里保持,因此能够使外顶片9A更迅速地成为干燥的状态。因此,能够使外顶片9A的弱酸性的性质更充分地发挥。Moreover, the absorber 8 has the through-hole 8TH which penetrates in the thickness direction. Thereby, the urine accumulated in the space S1 can be moved from the surface on the skin side of the absorber 8 (the surface on the top sheet 9 side in FIG. 11 ) to the surface on the non-skin side (the back sheet 7 in FIG. 11 ). side surface) to move. Furthermore, since the through-hole 8TH is provided in the urethral orifice corresponding region 40 in the space S1, the urine accumulated in the space S1 can be efficiently moved to the surface of the absorber 8 on the non-skin surface side. Thereby, the urine accumulated in the space S1 can be quickly infiltrated and held not only on the surface on the skin side but also on the surface on the non-skin side, so that the outer top sheet 9A can be brought into a dry state more quickly. Therefore, the weakly acidic property of the outer top sheet 9A can be more fully exhibited.

而且,能够利用贯通孔8TH避免使尿集中地浸入吸收体8的皮肤面侧并在那里保持的情形。因此,能够抑制从吸收体8的皮肤面侧的表面产生回流。Furthermore, the through-hole 8TH can avoid a situation where urine is concentratedly infiltrated into the skin surface side of the absorber 8 and held there. Therefore, it is possible to suppress the occurrence of backflow from the surface of the absorber 8 on the skin side.

<第2实施方式的变形例1><Variation 1 of the second embodiment>

接着,对第2实施方式的变形例1的尿布1进行说明。图12A和图12B是示意性地示出将本变形例的尿布1展开并伸长的状态的图。如图12A和图12B所示,在本变形例的尿布1中,吸收体8具有多个贯通孔8TH(在本变形例中为2个)。多个贯通孔8TH设置于尿道口对应区域40的周边的区域。例如,多个贯通孔8TH设置在尿道口对应区域40与槽8TL、8TR的腹侧端部之间。在本变形例的尿布1中,由于贯通孔8TH设置于尿道口对应区域40的周边的区域,因此多个贯通孔8TH经由顶片9也难以与尿道口抵接。由此,尿布1能够防止由贯通孔8TH对尿道口造成刺激,防止尿道口附近的皮肤问题的产生。Next, the diaper 1 of the modification 1 of 2nd Embodiment is demonstrated. 12A and 12B are diagrams schematically showing a state in which the diaper 1 of the present modification is unfolded and stretched. As shown in FIGS. 12A and 12B , in the diaper 1 of the present modification, the absorber 8 has a plurality of through holes 8TH (two in the present modification). The plurality of through holes 8TH are provided in the area around the urethral orifice corresponding area 40 . For example, the plurality of through holes 8TH are provided between the urethral orifice corresponding region 40 and the ventral end portions of the grooves 8TL and 8TR. In the diaper 1 of the present modification, since the through holes 8TH are provided in the peripheral region of the urethral orifice corresponding region 40 , the plurality of through-holes 8TH are less likely to come into contact with the urethral orifice via the top sheet 9 . Thereby, the diaper 1 can prevent stimulation of the urethral orifice by the through hole 8TH, and can prevent the occurrence of skin problems in the vicinity of the urethral orifice.

<第2实施方式的变形例2><Variation 2 of the second embodiment>

接着,对第2实施方式的变形例2的尿布1进行说明。图13是从本变形例的尿布1中仅提取吸收体8并从非皮肤面侧观察吸收体8的平面图。另外,图14是说明本变形例的尿布1中的穿戴者所排出的尿的流动的图。Next, the diaper 1 of the modification 2 of 2nd Embodiment is demonstrated. Fig. 13 is a plan view of the diaper 1 of the present modification, in which only the absorber 8 is extracted, and the absorber 8 is viewed from the non-skin surface side. Moreover, FIG. 14 is a figure explaining the flow of the urine excreted by the wearer in the diaper 1 of this modification.

在本变形例的尿布1中,与第2实施方式的尿布1相同,吸收体8在皮肤面侧的表面具有在长度方向上延伸的一对槽8TL、8TR。而且,如图13所示,吸收体8在非皮肤面侧的表面中具有在长度方向上延伸的一对槽8UL、8UR。一对槽8UL、8UR具有从吸收体8的非皮肤面侧的表面在厚度方向上向皮肤面侧凹陷的凹状,以下裆区域1B为中心延伸。槽8UL、8UR具有彼此相同的长度、宽度及深度,在尿布1的长度方向上配置于相同的位置。另外,槽8UL、8UR相对于尿布1的宽度方向的中心对称地配置,相互平行地形成。另外,槽8UL、8UR各自的中心线彼此的间隔W及从尿布1的长度方向的中央起一对槽8UL、8UR的腹部端部的长度L1设定为与第1实施方式的尿布1中的槽8SL、8SR各自的中心线彼此的间隔W及从尿布1的长度方向的中央起一对槽8SL、8SR的腹部端部的长度L1相同的值。In the diaper 1 of this modification, like the diaper 1 of 2nd Embodiment, the absorber 8 has a pair of groove|channel 8TL and 8TR extended in the longitudinal direction on the surface of the skin surface side. Moreover, as shown in FIG. 13, the absorber 8 has a pair of groove|channels 8UL and 8UR extended in the longitudinal direction in the surface of the non-skin surface side. The pair of grooves 8UL and 8UR have a concave shape recessed from the surface on the non-skin surface side of the absorber 8 toward the skin surface side in the thickness direction, and extend around the crotch region 1B. The grooves 8UL and 8UR have the same length, width, and depth, and are arranged at the same position in the longitudinal direction of the diaper 1 . Moreover, the grooves 8UL and 8UR are symmetrically arranged with respect to the center of the width direction of the diaper 1, and are formed in parallel to each other. In addition, the interval W between the center lines of the grooves 8UL and 8UR and the length L1 of the abdominal ends of the pair of grooves 8UL and 8UR from the center in the longitudinal direction of the diaper 1 are set to be the same as those in the diaper 1 of the first embodiment. The space|interval W between the center lines of each groove|channel 8SL, 8SR and the length L1 of the abdominal edge part of a pair of groove|channel 8SL and 8SR from the center of the longitudinal direction of the diapar 1 are the same value.

在本变形例的尿布1中,与第2实施方式的尿布1相同地,在吸收体8设置有贯通孔8TH,因此如图14中箭头所示,能够使积存于积存尿的空间S1的尿经由贯通孔8TH而从吸收体8的皮肤面侧的表面向非皮肤面侧的表面移动。而且,在本变形例的尿布1中,由于在吸收体8设置有在长度方向上延伸的槽8UL、8UR,因此能够使移动到吸收体8的非皮肤面侧的尿经由槽8UL、8UR而在吸收体8的非皮肤面侧从前身区域1F侧的区域通过下裆区域1B侧的区域向后身区域1R侧的区域(在图14中为从右侧的区域通过中央的区域向左侧的区域)迅速地移动。由此,能够使积存于空间S1的尿向吸收体8的非皮肤面侧的长度方向的整体迅速地浸入并在那里保持,因此能够使外顶片9A更迅速地成为干燥的状态。因此,能够使外顶片9A的弱酸性的性质更充分地发挥。In the diaper 1 of the present modification, as in the diaper 1 of the second embodiment, the absorber 8 is provided with the through holes 8TH, and thus, as shown by the arrows in FIG. 14 , the urine accumulated in the urine accumulation space S1 can be The absorber 8 moves from the surface on the skin side to the surface on the non-skin side through the through holes 8TH. Furthermore, in the diaper 1 of this modification, since the grooves 8UL and 8UR extending in the longitudinal direction are provided in the absorber 8, the urine that has moved to the non-skin surface side of the absorber 8 can be passed through the grooves 8UL and 8UR. On the non-skin surface side of the absorber 8, from the area on the front body region 1F side through the area on the crotch region 1B side to the area on the back body region 1R side (in FIG. area) move rapidly. Thereby, the urine accumulated in the space S1 can be quickly infiltrated and held in the entire longitudinal direction of the non-skin surface side of the absorber 8, so that the outer topsheet 9A can be brought into a dry state more quickly. Therefore, the weakly acidic property of the outer top sheet 9A can be more fully exhibited.

此外,在本变形例的尿布1中,在吸收体8的皮肤面侧及非皮肤面侧这两者的表面设置有槽8TL、8TR、8UL、8UR,但不限定于此。例如,也可以不在吸收体8的皮肤面侧的表面设置槽8TL、8TR,而仅在吸收体8的非皮肤面侧的表面设置槽8UL、8UR。Moreover, in the diaper 1 of this modification, although the groove|channel 8TL, 8TR, 8UL, 8UR is provided in the surface of both the skin surface side and the non-skin surface side of the absorber 8, it is not limited to this. For example, the grooves 8TL and 8TR may not be provided on the surface of the absorber 8 on the skin side, and the grooves 8UL and 8UR may be provided only on the surface on the non-skin side of the absorber 8 .

<第3实施方式><Third Embodiment>

接着,对第3实施方式进行说明。在上述第1实施方式的尿布1中,顶片9具有包含外顶片9A和内顶片9B这2个片的多层构造,但本实用新型不限于此。例如,顶片9也可以具有包含1个片的单层构造。Next, the third embodiment will be described. In the diaper 1 of the said 1st Embodiment, although the top sheet 9 has the multilayer structure which consists of 2 sheets of the outer top sheet 9A and the inner top sheet 9B, this invention is not limited to this. For example, the top sheet 9 may have a single-layer structure including one sheet.

在本实施方式的尿布1中,顶片9是与穿戴者的皮肤抵接的透液性的1个片,包含pH调整成分并具有弱酸性的性质。作为pH调整成分,使用有机酸、例如安全性高且在尿布1的使用前的状态下实质上无臭的苹果酸或柠檬酸。顶片9通过在中性的片上涂布含有有机酸的药液而制成。本实施方式的尿布1除了顶片9的结构以外,具有与图3A和图3B所示的第1实施方式的尿布1相同的结构。因此,在本实施方式中,省略顶片9的结构以外的说明。In the diaper 1 of the present embodiment, the top sheet 9 is a single liquid-permeable sheet that is in contact with the wearer's skin, contains a pH adjusting component, and has a weakly acidic property. As a pH adjustment component, an organic acid, for example, malic acid or citric acid which is highly safe and is substantially odorless in the state before use of the diaper 1 is used. The top sheet 9 is produced by applying a chemical solution containing an organic acid on a neutral sheet. The diaper 1 of this embodiment has the same structure as the diaper 1 of 1st Embodiment shown to FIG. 3A and FIG. 3B except the structure of the top sheet 9. FIG. Therefore, in this embodiment, the description other than the structure of the top sheet 9 is abbreviate|omitted.

由于顶片9为弱酸性,因此即使发生了在第1实施方式中说明的回流,也能够用顶片9的pH调整成分来中和被吸收体8保持着的从穿戴者排泄出的液体中含有的氨等碱成分。因此,能够将穿戴者的皮肤从弱酸性维持为中性,能够抑制产生皮肤问题。Since the top sheet 9 is weakly acidic, even if the backflow described in the first embodiment occurs, the pH adjusting component of the top sheet 9 can neutralize the liquid excreted from the wearer held by the absorber 8. Contains ammonia and other alkali components. Therefore, the wearer's skin can be maintained from weakly acidic to neutral, and the occurrence of skin problems can be suppressed.

但是,如在第1实施方式中说明的那样,本申请发明人发现:在顶片9处于被回流的液体等润湿的状态的情况下,由于顶片9被该液体覆盖,因此有时无法充分地发挥顶片9的弱酸性的性质。However, as described in the first embodiment, the inventors of the present application have found that when the top sheet 9 is in a state of being wetted by a backflowed liquid or the like, since the top sheet 9 is covered by the liquid, sometimes it is not possible to fully The weak acidity of the topsheet 9 is fully exerted.

因此,在本实施方式的尿布1中,吸收体8具有在厚度方向上贯通吸收体8的槽8SL、8SR,以使得能够充分地发挥片的性质。Therefore, in the diaper 1 of this embodiment, the absorber 8 has the grooves 8SL and 8SR penetrating the absorber 8 in the thickness direction so that the properties of the sheet can be sufficiently exhibited.

在本实施方式的尿布1中,与第1实施方式的尿布1同样地,即如图7中箭头所示,穿戴者所排出的尿通过顶片9而暂且积存于在吸收体8的前身区域1F侧的区域形成的积存尿的空间S1。在本实施方式中,通过吸收体8具有在厚度方向上贯通吸收体8的槽8SL、8SR,从而能够使积存于空间S1的尿经由槽8SL、8SR而从吸收体8的皮肤面侧的表面(在图7中为顶片9侧的表面)向非皮肤面侧的表面(在图7中为背片7侧的表面)移动。由此,能够使积存于空间S1的尿不仅向吸收体8的皮肤面侧的表面,还向非皮肤面侧的表面迅速地浸入并保持,因此能够使顶片9迅速地成为干燥的状态。因此,能够使顶片9的弱酸性的性质充分地发挥。In the diaper 1 of the present embodiment, similarly to the diaper 1 of the first embodiment, that is, as shown by the arrow in FIG. 7 , the urine discharged by the wearer is temporarily accumulated in the front region of the absorber 8 through the top sheet 9 . The space S1 for storing urine formed by the area on the 1F side. In the present embodiment, since the absorber 8 has the grooves 8SL and 8SR penetrating the absorber 8 in the thickness direction, the urine accumulated in the space S1 can pass through the grooves 8SL and 8SR from the surface of the absorber 8 on the skin side. (The surface on the side of the top sheet 9 in FIG. 7 ) moves to the surface on the side of the non-skin surface (the surface on the side of the back sheet 7 in FIG. 7 ). Thereby, the urine accumulated in the space S1 can be quickly infiltrated and held not only on the surface of the absorber 8 on the skin side but also on the surface on the non-skin side, so that the top sheet 9 can be quickly brought into a dry state. Therefore, the weakly acidic property of the top sheet 9 can be sufficiently exhibited.

而且,能够利用在厚度方向上贯通的槽8SL、8SR使积存于空间S1的尿从吸收体8的皮肤面侧的表面向非皮肤面侧的表面移动,因此能够避免使尿集中地浸入吸收体8的皮肤面侧并在那里保持的情形。因此,能够抑制从吸收体8的皮肤面侧的表面产生回流。Furthermore, since the urine accumulated in the space S1 can be moved from the skin-side surface of the absorber 8 to the non-skin-side surface by the grooves 8SL and 8SR penetrating in the thickness direction, it is possible to avoid concentrated infiltration of urine into the absorber. 8 is the case where the skin faces and remains there. Therefore, it is possible to suppress the occurrence of backflow from the surface of the absorber 8 on the skin side.

而且,通过使槽8SL、8SR在长度方向上延伸,从而能够使积存于空间S1的尿经由槽8SL、8SR而从前身区域1F侧的区域通过下裆区域1B侧的区域向后身区域1R侧的区域(在图7中为从右侧的区域通过中央的区域向左侧的区域)迅速地移动。由此,能够使积存于空间S1的尿向吸收体8的长度方向的整体迅速地浸入并保持,因此能够使顶片9更迅速地成为干燥的状态。因此,能够使顶片9的弱酸性的性质更充分地发挥。Furthermore, by extending the grooves 8SL and 8SR in the longitudinal direction, the urine accumulated in the space S1 can pass through the grooves 8SL and 8SR from the front body region 1F side through the crotch region 1B side to the back body region 1R side. The area of (in FIG. 7, from the area on the right to the area on the left through the central area) moves rapidly. Thereby, since the urine accumulated in the space S1 can be quickly infiltrated and held in the entire longitudinal direction of the absorber 8, the top sheet 9 can be brought into a dry state more quickly. Therefore, the weakly acidic property of the top sheet 9 can be more fully exhibited.

而且,能够利用在长度方向上延伸的槽8SL、8SR,使积存于空间S1的尿不仅向吸收体8的空间S1、即尿道口对应区域40及其周边的区域移动,还向下裆区域1B侧的区域、后身区域1R侧的区域移动,因此能够避免使尿集中地浸入吸收体8的尿道口对应区域40及其周边的区域并在那里保持的情形。因此,能够抑制从吸收体8的尿道口对应区域40及其周边的区域产生回流。Furthermore, by the grooves 8SL and 8SR extending in the longitudinal direction, the urine accumulated in the space S1 can be moved not only to the space S1 of the absorber 8, that is, to the urethral orifice corresponding region 40 and its surrounding regions, but also to the crotch region 1B. Since the side area and the area on the back body area 1R side are moved, it is possible to avoid the situation where urine is concentratedly infiltrated into the urethral orifice corresponding area 40 of the absorber 8 and the surrounding area and held there. Therefore, it is possible to suppress the occurrence of backflow from the urethral orifice corresponding region 40 of the absorber 8 and the region around it.

<第4实施方式><4th Embodiment>

接着,对第4实施方式进行说明。在上述第3实施方式的尿布1中,槽8SL、8SR在厚度方向上贯通吸收体8,但本实用新型不限于此。例如,如第2实施方式的尿布1那样,槽8SL、8SR也可以形成为非贯通的凹状。Next, the fourth embodiment will be described. In the diaper 1 of the said 3rd Embodiment, although the groove|channel 8SL and 8SR penetrates the absorber 8 in the thickness direction, this invention is not limited to this. For example, as in the diaper 1 of the second embodiment, the grooves 8SL and 8SR may be formed in a non-penetrating concave shape.

在本实施方式的尿布1中,与第3实施方式的尿布1相同,顶片9是与穿戴者的皮肤抵接的透液性的1个片,包含pH调整成分并具有弱酸性的性质。In the diaper 1 of the present embodiment, like the diaper 1 of the third embodiment, the top sheet 9 is a single liquid-permeable sheet that is in contact with the wearer's skin, contains a pH adjusting component, and has a weakly acidic property.

并且,与图10A和图10B所示的第2实施方式的尿布1相同,吸收体8具有在尿布1的长度方向上延伸的一对槽8TL、8TR。一对槽8TL、8TR具有从吸收体8的皮肤面侧的表面在厚度方向上向非皮肤面侧凹陷的凹状,以下裆区域1B为中心延伸。槽8TL、8TR具有彼此相同的长度、宽度及深度,在尿布1的长度方向上配置于相同的位置。另外,槽8TL、8TR相对于尿布1的宽度方向的中心对称地配置,相互平行地形成。另外,槽8TL、8TR各自的中心线彼此的间隔W及从尿布1的长度方向的中央起一对槽8TL、8TR的腹部端部的长度L1设定为与第1实施方式中的槽8SL、8SR各自的中心线彼此的间隔W及从尿布1的长度方向的中央起一对槽8SL、8SR的腹部端部的长度L1相同的值。通过这样的槽8TL、8TR的结构及配置,从而在本实施方式的尿布1中,也与第3实施方式的尿布1相同地,在吸收体8中的前身区域1F侧的区域形成积存尿的空间S1。Moreover, like the diaper 1 of 2nd Embodiment shown to FIG. 10A and FIG. 10B, the absorber 8 has a pair of groove|channel 8TL and 8TR extended in the longitudinal direction of the diaper 1. FIG. The pair of grooves 8TL and 8TR has a concave shape recessed in the thickness direction from the surface of the absorber 8 on the skin surface side toward the non-skin surface side, and extends around the crotch region 1B. The grooves 8TL and 8TR have mutually the same length, width, and depth, and are arranged at the same position in the longitudinal direction of the diaper 1 . Moreover, grooves 8TL and 8TR are symmetrically arrange|positioned with respect to the center of the width direction of the diapar 1, and are formed in parallel with each other. In addition, the distance W between the center lines of the grooves 8TL and 8TR and the length L1 of the abdominal end of the pair of grooves 8TL and 8TR from the center in the longitudinal direction of the diaper 1 are set to be the same as the grooves 8SL and 8TR in the first embodiment. The space|interval W of each center line of 8SR and the length L1 of the abdominal edge part of a pair of groove|channel 8SL and 8SR from the center of the longitudinal direction of the diapar 1 are the same value. By the structure and arrangement of such grooves 8TL and 8TR, in the diaper 1 of the present embodiment, similarly to the diaper 1 of the third embodiment, the area on the front body region 1F side of the absorber 8 is formed to store urine. Space S1.

另外,吸收体8具有在吸收体8的厚度方向上贯通的圆形状的贯通孔8TH。贯通孔8TH设置于尿道口对应区域40。此外,贯通孔8TH的形状不限定于圆形状。例如,贯通孔8TH的形状也可以是椭圆形状。Moreover, the absorber 8 has the circular through-hole 8TH which penetrates in the thickness direction of the absorber 8. As shown in FIG. The through hole 8TH is provided in the region 40 corresponding to the urethra orifice. In addition, the shape of the through-hole 8TH is not limited to a circular shape. For example, the shape of the through hole 8TH may be an elliptical shape.

在本实施方式的尿布1中,通过吸收体8具有在吸收体8的厚度方向上贯通的贯通孔8TH,从而能够使积存于积存尿的空间S1的尿与第2实施方式的尿布1同样地,即如图11中箭头所示那样,从吸收体8的皮肤面侧的表面(在图11中为顶片9侧的表面)向非皮肤面侧的表面(在图11中为背片7侧的表面)移动。而且,由于贯通孔8TH设置于空间S1内的尿道口对应区域40,因此能够使积存于空间S1的尿高效地向吸收体8的非皮肤面侧的表面移动。由此,能够使积存于空间S1的尿不仅向吸收体8的皮肤面侧的表面,还向非皮肤面侧的表面迅速地浸入并在那里保持,因此能够使顶片9迅速地成为干燥的状态。因此,能够使顶片9的弱酸性的性质充分地发挥。In the diaper 1 of the present embodiment, since the absorber 8 has the through-hole 8TH penetrating in the thickness direction of the absorber 8, the urine accumulated in the urine storage space S1 can be stored in the same manner as the diaper 1 of the second embodiment. That is, as shown by the arrow in FIG. 11 , from the surface of the absorber 8 on the skin side (the surface on the top sheet 9 side in FIG. 11 ) to the surface on the non-skin side (the back sheet 7 in FIG. 11 ) side surface) to move. Furthermore, since the through-hole 8TH is provided in the urethral orifice corresponding region 40 in the space S1, the urine accumulated in the space S1 can be efficiently moved to the surface of the absorber 8 on the non-skin surface side. Thereby, the urine accumulated in the space S1 can be quickly infiltrated not only to the surface of the absorber 8 on the skin side but also to the surface of the non-skin side and retained there, so that the top sheet 9 can be quickly dried state. Therefore, the weakly acidic property of the top sheet 9 can be sufficiently exhibited.

而且,能够利用贯通孔8TH避免使尿集中地浸入吸收体8的皮肤面侧并在那里保持的情形。因此,能够抑制从吸收体8的皮肤面侧的表面产生回流。Furthermore, the through-hole 8TH can avoid a situation where urine is concentratedly infiltrated into the skin surface side of the absorber 8 and held there. Therefore, it is possible to suppress the occurrence of backflow from the surface of the absorber 8 on the skin side.

另外,通过吸收体8具有在长度方向上延伸的槽8TL、8TR,从而能够使积存于空间S1的尿经由槽8TL、8TR而在吸收体8的皮肤面侧从前身区域1F侧的区域通过下裆区域1B侧的区域向后身区域1R侧的区域(在图11中为从右侧的区域通过中央的区域向左侧的区域)迅速地移动。由此,能够使积存于空间S1的尿向吸收体8的皮肤面侧的长度方向的整体迅速地浸入并保持,因此能够使顶片9更迅速地成为干燥的状态。因此,能够使顶片9的弱酸性的性质更充分地发挥。In addition, since the absorber 8 has the grooves 8TL and 8TR extending in the longitudinal direction, the urine accumulated in the space S1 can pass through the skin surface side of the absorber 8 from the area on the front body area 1F side through the grooves 8TL and 8TR. The region on the side of the crotch region 1B moves rapidly toward the region on the side of the back body region 1R (in FIG. 11 , from the region on the right through the central region to the region on the left). Thereby, the urine accumulated in the space S1 can be quickly infiltrated and held in the entire longitudinal direction of the skin surface side of the absorber 8, so that the top sheet 9 can be brought into a dry state more quickly. Therefore, the weakly acidic property of the top sheet 9 can be more fully exhibited.

而且,能够利用槽8TL、8TR避免使尿集中地浸入吸收体8的尿道口对应区域40及其周边的区域并在那里保持的情形。因此,能够抑制从吸收体8的尿道口对应区域40及其周边的区域产生回流。Furthermore, the grooves 8TL and 8TR can prevent urine from being concentrated in the urethral orifice corresponding region 40 of the absorber 8 and its surrounding region and held there. Therefore, it is possible to suppress the occurrence of backflow from the urethral orifice corresponding region 40 of the absorber 8 and the region around it.

<第4实施方式的变形例1><Modification 1 of the fourth embodiment>

接着,对第4实施方式的变形例1的尿布1进行说明。在本变形例的尿布1中,吸收体8与图12A和图12B所示的第2实施方式的变形例1的尿布1相同,具有多个贯通孔8TH(在本变形例中为2个)。多个贯通孔8TH设置于尿道口对应区域40的周边的区域。例如,多个贯通孔8TH设置于尿道口对应区域40与槽8TL、8TR的腹侧端部之间。在本变形例的尿布1中,由于贯通孔8TH设置于尿道口对应区域40的周边的区域,因此多个贯通孔8TH经由顶片9也难以与尿道口抵接。由此,尿布1能够防止由贯通孔8TH对尿道口造成刺激,防止产生尿道口附近的皮肤问题。Next, the diaper 1 of the modification 1 of 4th Embodiment is demonstrated. In the diaper 1 of the present modification, the absorber 8 is the same as the diaper 1 of the modification 1 of the second embodiment shown in FIGS. 12A and 12B , and has a plurality of through holes 8TH (two in the present modification) . The plurality of through holes 8TH are provided in the area around the urethral orifice corresponding area 40 . For example, the plurality of through holes 8TH are provided between the urethral orifice corresponding region 40 and the ventral end portions of the grooves 8TL and 8TR. In the diaper 1 of the present modification, since the through holes 8TH are provided in the peripheral region of the urethral orifice corresponding region 40 , the plurality of through-holes 8TH are less likely to come into contact with the urethral orifice via the top sheet 9 . Thereby, the diaper 1 can prevent the stimulation of the urethral orifice from the through-hole 8TH, and can prevent the occurrence of skin problems in the vicinity of the urethral orifice.

<第4实施方式的变形例2><Variation 2 of the fourth embodiment>

接着,对第4实施方式的变形例2的尿布1进行说明。在本变形例的尿布1中,与第4实施方式的尿布1相同,即与图10A和图10B所示的第2实施方式的尿布1相同,吸收体8在皮肤面侧的表面中具有在长度方向上延伸的一对槽8TL、8TR。而且,吸收体8与图13所示的第2实施方式的变形例2的尿布1相同,在非皮肤面侧的表面中具有在长度方向上延伸的一对槽8UL、8UR。一对槽8UL、8UR具有从吸收体8的非皮肤面侧的表面在厚度方向上向皮肤面侧凹陷的凹状,以下裆区域1B为中心延伸。槽8UL、8UR具有彼此相同的长度、宽度及深度,在尿布1的长度方向上配置于相同的位置。另外,槽8UL、8UR相对于尿布1的宽度方向的中心对称地配置,相互平行地形成。另外,槽8UL、8UR各自的中心线彼此的间隔W及从尿布1的长度方向的中央起一对槽8UL、8UR的腹部端部的长度L1设定为与第1实施方式的尿布1中的槽8SL、8SR各自的中心线彼此的间隔W及从尿布1的长度方向的中央起一对槽8SL、8SR的腹部端部的长度L1相同的值。Next, the diaper 1 of the modification 2 of 4th Embodiment is demonstrated. In the diaper 1 of the present modification, the absorber 8 has on the surface of the skin surface side the same as the diaper 1 of the fourth embodiment, that is, the same as the diaper 1 of the second embodiment shown in FIGS. 10A and 10B . A pair of grooves 8TL and 8TR extending in the longitudinal direction. Moreover, the absorber 8 has a pair of groove|channels 8UL and 8UR extended in the longitudinal direction in the surface of the non-skin surface side similarly to the diaper 1 of the modification 2 of 2nd Embodiment shown in FIG. 13. The pair of grooves 8UL and 8UR have a concave shape recessed from the surface on the non-skin surface side of the absorber 8 toward the skin surface side in the thickness direction, and extend around the crotch region 1B. The grooves 8UL and 8UR have the same length, width, and depth, and are arranged at the same position in the longitudinal direction of the diaper 1 . Moreover, the grooves 8UL and 8UR are symmetrically arranged with respect to the center of the width direction of the diaper 1, and are formed in parallel to each other. In addition, the interval W between the center lines of the grooves 8UL and 8UR and the length L1 of the abdominal ends of the pair of grooves 8UL and 8UR from the center in the longitudinal direction of the diaper 1 are set to be the same as those in the diaper 1 of the first embodiment. The space|interval W between the center lines of each groove|channel 8SL, 8SR and the length L1 of the abdominal edge part of a pair of groove|channel 8SL and 8SR from the center of the longitudinal direction of the diapar 1 are the same value.

在本变形例的尿布1中,与第2实施方式的尿布1相同,在吸收体8设置有贯通孔8TH,因此如图11中箭头所示,能够使积存于积存尿的空间S1的尿经由贯通孔8TH而从吸收体8的皮肤面侧的表面向非皮肤面侧的表面移动。而且,在本变形例的尿布1中,由于在吸收体8设置有在长度方向上延伸的槽8UL、8UR,因此能够使移动到吸收体8的非皮肤面侧的尿经由槽8UL、8UR而在吸收体8的非皮肤面侧从前身区域1F侧的区域通过下裆区域1B侧的区域向后身区域1R侧的区域(在图11中为从右侧的区域通过中央的区域向左侧的区域)迅速地移动。由此,能够使积存于空间S1的尿向吸收体8的非皮肤面侧的长度方向的整体迅速地浸入并在那里保持,因此能够使顶片9更迅速地成为干燥的状态。因此,能够使顶片9的弱酸性的性质更充分地发挥。In the diaper 1 of the present modification, as in the diaper 1 of the second embodiment, the absorber 8 is provided with the through holes 8TH. Therefore, as shown by the arrow in FIG. 11 , the urine accumulated in the urine accumulation space S1 can be passed through. The through-hole 8TH moves from the surface on the skin side of the absorber 8 to the surface on the non-skin side. Furthermore, in the diaper 1 of this modification, since the grooves 8UL and 8UR extending in the longitudinal direction are provided in the absorber 8, the urine that has moved to the non-skin surface side of the absorber 8 can be passed through the grooves 8UL and 8UR. On the non-skin surface side of the absorber 8, from the region on the front body region 1F side through the region on the crotch region 1B side to the region on the back body region 1R side (in FIG. 11, from the region on the right through the central region to the left side area) move rapidly. Thereby, the urine accumulated in the space S1 can be quickly infiltrated and held in the entire longitudinal direction of the non-skin surface side of the absorber 8, so that the top sheet 9 can be brought into a dry state more quickly. Therefore, the weakly acidic property of the top sheet 9 can be more fully exhibited.

此外,在本变形例的尿布1中,在吸收体8的皮肤面侧及非皮肤面侧这两者的表面设置有槽8TL、8TR、8UL、8UR,但不限定于此。例如,也可以不在吸收体8的皮肤面侧的表面设置槽8TL、8TR,而仅在吸收体8的非皮肤面侧的表面设置槽8UL、8UR。Moreover, in the diaper 1 of this modification, although the groove|channel 8TL, 8TR, 8UL, 8UR is provided in the surface of both the skin surface side and the non-skin surface side of the absorber 8, it is not limited to this. For example, the grooves 8TL and 8TR may not be provided on the surface of the absorber 8 on the skin side, and the grooves 8UL and 8UR may be provided only on the surface on the non-skin side of the absorber 8 .

<第5实施方式><Fifth Embodiment>

接着,对第5实施方式进行说明。在第3实施方式的尿布1中,顶片9包含pH调整成分并具有弱酸性的性质,但本实用新型不限于此。例如,顶片9也可以具有中性的性质。Next, the fifth embodiment will be described. In the diaper 1 of 3rd Embodiment, although the top sheet 9 contains a pH adjustment component and has a weakly acidic property, this invention is not limited to this. For example, the topsheet 9 may also have neutral properties.

FIG. 15A schematically shows the internal structure of the diaper 1 in the unfolded and extended state as viewed from the left side. FIG. 15B schematically shows a plan view of the diaper 1 in a state of being unfolded and stretched. The diaper 1 of the present embodiment has basically the same structure as the diaper 1 of the third embodiment except for the properties of the top sheet. Therefore, in the diaper 1 of this embodiment, the same code|symbol is attached|subjected to the same component as the diaper 1 of 3rd Embodiment, and the description is abbreviate|omitted.

在本实施方式的尿布1中,顶片29是与穿戴者的皮肤抵接的透液性的1个片,具有中性的性质。In the diaper 1 of the present embodiment, the top sheet 29 is a single liquid-permeable sheet that is in contact with the wearer's skin, and has neutral properties.

在第1实施方式中,对将尿布1以将其长度方向的端部彼此重叠的方式对折了的情况下的从长度方向的中央起一对槽8SL、8SR的腹侧端部的长度L1进行了规定,但在本实施方式中,还规定从长度方向的中央起一对槽8SL、8SR的背侧端部的长度。在将尿布1以双点划线FL对折了的情况下,在从尿布1的长度方向的中央(双点划线FL)起一对槽8SL、8SR的背侧端部的长度(图15B中的L4)处于40mm以上且50mm以下的范围内的情况下,尿布1适合用于体重处于5kg以上且13kg以下的范围内的婴幼儿。另外,在将尿布1以双点划线FL对折了的情况下,在从尿布1的长度方向的中央(双点划线FL)起一对槽8SL、8SR的背侧端部的长度(L4)处于65mm以上且75mm以下的范围内的情况下,尿布1适合用于体重处于8kg以上且15kg以下的范围内的婴幼儿。另外,在将尿布1以双点划线FL对折了的情况下,在从尿布1的长度方向的中央(双点划线FL)起一对槽8SL、8SR的背侧端部的长度(L4)处于40mm以上且50mm以下的范围内的情况下,尿布1适合用于体重处于11kg以上且23kg以下的范围内的婴幼儿。另外,在将尿布1以双点划线FL对折了的情况下,在从尿布1的长度方向的中央(双点划线FL)起一对槽8SL、8SR的背侧端部的长度(L4)处于50mm以上且60mm以下的范围内的情况下,尿布1适合用于体重处于12kg以上且29kg以下的范围内的婴幼儿。In 1st Embodiment, when the diaper 1 is folded in half so that the edge parts of the longitudinal direction may overlap each other, the length L1 of the abdominal side edge part of a pair of groove|channels 8SL and 8SR from the center of the longitudinal direction is performed. Although it is prescribed|regulated, in this embodiment, the length of the back side edge part of a pair of groove|channels 8SL and 8SR from the center of a longitudinal direction is also prescribed|regulated. When the diaper 1 is folded in half by the dashed double-dotted line FL, the length of the back side end of the pair of grooves 8SL and 8SR from the center (the dashed double-dotted line FL) in the longitudinal direction of the diaper 1 (in FIG. 15B ) When L4) is in the range of 40 mm or more and 50 mm or less, the diaper 1 is suitable for infants and young children whose weight is in the range of 5 kg or more and 13 kg or less. Moreover, when the diaper 1 is folded in half by the dashed-two-dotted line FL, the length (L4) of the back side edge part of a pair of groove|channels 8SL and 8SR from the center of the longitudinal direction of the diaper 1 (the dashed-two-dotted line FL) ) in the range of 65 mm or more and 75 mm or less, the diaper 1 is suitable for infants and young children whose weight is in the range of 8 kg or more and 15 kg or less. Moreover, when the diaper 1 is folded in half by the dashed-two-dotted line FL, the length (L4) of the back side edge part of a pair of groove|channels 8SL and 8SR from the center of the longitudinal direction of the diaper 1 (the dashed-two-dotted line FL) ) in the range of 40 mm or more and 50 mm or less, the diaper 1 is suitable for infants and young children whose weight is in the range of 11 kg or more and 23 kg or less. Moreover, when the diaper 1 is folded in half by the dashed-two-dotted line FL, the length (L4) of the back side edge part of a pair of groove|channels 8SL and 8SR from the center of the longitudinal direction of the diaper 1 (the dashed-two-dotted line FL) ) in the range of 50 mm or more and 60 mm or less, the diaper 1 is suitable for infants and young children whose weight is in the range of 12 kg or more and 29 kg or less.

此外,优选不仅在尿道口对应区域40不配置线状橡胶等伸缩性构件(弹性构件),而且在肛门对应区域30也不配置线状橡胶等伸缩性构件(弹性构件)。通过在肛门对应区域30不配置伸缩性构件,从而能够防止妨碍保持粪便的空间的形成。In addition, it is preferable not only to dispose stretchable members (elastic members) such as linear rubber in the urethral orifice corresponding region 40 , but also not to dispose stretchable members (elastic members) such as linear rubber in the anus corresponding region 30 . By not arranging the stretchable member in the anus-corresponding region 30, it is possible to prevent the formation of a space that hinders the holding of feces.

另外,保持粪便的空间通过由尿布1从在图15B中用粗虚线呈矩形状地图示的假想的立起线L5向非皮肤面侧呈拱顶状鼓起而形成。以下,对立起线L5的位置进行说明。In addition, the space for holding feces is formed by the diaper 1 bulging in a dome shape toward the non-skin surface side from an imaginary rising line L5 shown in a rectangular shape with a thick broken line in FIG. 15B . Hereinafter, the position of the rising line L5 will be described.

腹部褶裥3T形成于肛门对应区域30的宽度方向的两侧且比一对槽8SL、8SR的背侧(后身区域1R侧)的延伸线上靠宽度方向的外侧的位置。此外,后身区域1R侧的腹部褶裥3T是线状橡胶4R4、4R5的配置区域,线状橡胶4R4、4R5配置于肛门对应区域30的宽度方向的两侧且比一对槽8SL、8SR的背侧(后身区域1R侧)的延伸线上靠宽度方向的外侧的位置。这是因为,在尿布1的穿戴状态下,需要至少包括肛门对应区域30在内地形成保持粪便的空间,但另一方面,若该空间过大,则有可能无法保持粪便,因此需要形成能够保持婴幼儿的1次排便量的程度的大小的空间。因此,在本实施方式中,不是通过将肛门对应区域30向皮肤面方向压靠,而是通过在比一对槽8SL、8SR的延伸线上靠宽度方向的外侧的位置利用线状橡胶4R4、4R5的收缩力将腹部褶裥3T的宽度方向端部向皮肤面方向压靠,从而将立起线L5的宽度方向端部规定在腹部褶裥3T的宽度方向端部。由此,尿布1能够防止该空间在宽度方向上过度地扩展。The abdominal gathers 3T are formed on both sides in the width direction of the anus-corresponding region 30 and on the outer side in the width direction with respect to the extension line of the back side (back body region 1R side) of the pair of grooves 8SL and 8SR. In addition, the abdomen gather 3T on the side of the back body region 1R is an arrangement region of the linear rubbers 4R4 and 4R5, and the linear rubbers 4R4 and 4R5 are arranged on both sides in the width direction of the anus corresponding region 30 and are more than the pair of grooves 8SL and 8SR. The position on the outer side in the width direction on the extension line of the back side (back body region 1R side). This is because, in the wearing state of the diaper 1, a space for holding feces needs to be formed in the interior including at least the anus corresponding region 30. On the other hand, if the space is too large, there is a possibility that the feces cannot be held. Therefore, it is necessary to form a space capable of holding feces. A space of the size of one bowel movement of an infant. Therefore, in the present embodiment, instead of pressing the anus-corresponding region 30 in the direction of the skin surface, the linear rubber 4R4, The contraction force of 4R5 presses the width direction edge part of the abdominal gathers 3T against the skin surface direction, and defines the width direction edge part of the rising line L5 at the width direction edge part of the abdominal gather 3T. Thereby, the diaper 1 can prevent this space from spreading too much in the width direction.

另外,若考虑婴幼儿的肛门的位置等,则肛门对应区域30的在尿布1的长度方向上的长度(图15B中的L6)优选为50mm。另外,如图15A和图15B所示,配置于肛门对应区域30的宽度方向的外侧的线状橡胶4R4、4R5以比配置于一对槽8SL、8SR的背侧端部的宽度方向的外侧的线状橡胶4R5短的间隔配置。因此,腹部褶裥3T的在肛门对应区域30的宽度方向的外侧的伸缩力比一对槽8SL、8SR的背侧端部的宽度方向的外侧的伸缩力大。这是因为,由于槽8SL、8SR的背侧端部规定空间形成的下裆区域1B侧的立起线L5,因此只要在槽8SL、8SR的宽度方向外侧以必要充分的力将尿布1向皮肤方向压靠即可,但若肛门对应区域30的宽度方向外侧为与槽8SL、8SR的宽度方向外侧相同程度或比槽8SL、8SR的宽度方向外侧弱的伸缩力,则会导致空间在宽度方向上扩展,无法维持能够保持婴幼儿的1次排便量的大小的空间。对于本实施方式的尿布1,在腹部褶裥3T中,通过使肛门对应区域30的宽度方向的外侧的伸缩力比一对槽8SL、8SR的背侧端部的宽度方向的外侧的伸缩力大,从而能够防止空间变得过大,能够适当地维持保持粪便的空间。In addition, considering the position of the anus of infants and the like, the length (L6 in FIG. 15B ) of the anus-corresponding region 30 in the longitudinal direction of the diaper 1 is preferably 50 mm. In addition, as shown in FIGS. 15A and 15B , the linear rubbers 4R4 and 4R5 arranged on the outer side in the width direction of the anus corresponding region 30 are smaller than the linear rubbers 4R4 and 4R5 arranged on the outer side in the width direction of the back end portions of the pair of grooves 8SL and 8SR. Linear rubber 4R5 are arranged at short intervals. Therefore, the expansion-contraction force on the outer side in the width direction of the anus-corresponding region 30 of the abdominal gather 3T is larger than the expansion-contraction force on the outer side in the width direction of the dorsal ends of the pair of grooves 8SL and 8SR. This is because the back side ends of the grooves 8SL and 8SR define the rising line L5 on the side of the crotch region 1B formed by the space. Therefore, the diaper 1 can be pushed against the skin with a necessary and sufficient force on the outside in the width direction of the grooves 8SL and 8SR. However, if the outer side in the width direction of the anus-corresponding area 30 is the same as or weaker than the outer side in the width direction of the grooves 8SL and 8SR, it will cause the space in the width direction. It expands upward and cannot maintain a space of a size that can hold the amount of one bowel movement of an infant. In the diaper 1 of the present embodiment, in the abdominal gathers 3T, the expansion and contraction force of the outer side in the width direction of the anus corresponding region 30 is larger than the expansion and contraction force of the outer side in the width direction of the back end portions of the pair of grooves 8SL and 8SR. , the space can be prevented from becoming too large, and the space for holding the feces can be appropriately maintained.

另外,在肛门对应区域30的背侧设置有腰部褶裥3R。腰部褶裥3R通过将尿布1向皮肤面方向压靠,从而规定了保持粪便的空间的背侧的立起线L5。即,腰部褶裥3R的下裆区域1B侧(下裆区域1B侧的线状橡胶4R3)规定空间的背侧的立起线L5。本实施方式的尿布1能够利用腰部褶裥3R防止空间向背侧变得过大,能够适当地维持保持粪便的空间。In addition, waist gathers 3R are provided on the back side of the anus-corresponding region 30 . The waist gather 3R defines the raising line L5 on the back side of the space for holding the feces by pressing the diaper 1 in the direction of the skin surface. That is, the rising line L5 on the back side of the space is defined by the waist gather 3R on the crotch region 1B side (the linear rubber 4R3 on the crotch region 1B side). The diaper 1 of this embodiment can prevent the space from becoming too large to the back side by the waist gathers 3R, and can maintain the space for holding feces appropriately.

另外,如图15B所示,在平面观察尿布1的情况下,吸收体8的长度方向端部位于垫罩片6的背侧端部(后身区域1R侧的端部)的内侧,形成腰部褶裥3R的线状橡胶4R3的一部分与吸收体8重叠。由此,尿布1能够不将垫罩片6、吸收体8的背侧端部作为空间的背侧的立起线L5,而将腰部褶裥3R的下裆区域1B侧的端部规定为空间的背侧的立起线L5。假设将垫罩片6、吸收体8的背侧端部作为空间的物理上的立起线,则由于该物理上的立起线与尿道口及其周边的皮肤抵接,而可能产生皮肤问题等问题。对此,本实施方式的尿布1能够将腰部褶裥3R的下裆区域1B侧规定为空间的背侧的假想的立起线L5,因此能够形成保持粪便的空间,并且能够防止产生由于物理上的立起线与臀部抵接而可能产生的皮肤问题等问题。In addition, as shown in FIG. 15B , when the diaper 1 is viewed in plan, the longitudinal end of the absorber 8 is positioned inside the back end (end on the back body region 1R side) of the pad cover sheet 6 to form the waist. A part of the linear rubber 4R3 of the gathers 3R overlaps with the absorber 8 . Thereby, the diaper 1 can define the end of the waist gather 3R on the crotch region 1B side as the space without the back-side end of the cover sheet 6 and the absorber 8 being the back-side rising line L5 of the space. The dorsal erection line L5. Assuming that the back end of the cover sheet 6 and the absorber 8 is used as a physical rising line in the space, the physical rising line comes into contact with the skin around the urethra orifice, which may cause skin problems. And other issues. On the other hand, in the diaper 1 of the present embodiment, the crotch region 1B side of the waist gather 3R can be defined as the virtual rising line L5 on the back side of the space, so that a space for holding feces can be formed, and the occurrence of physical problems can be prevented. Skin problems and other problems that may occur due to the abutment of the erection line and the buttocks.

另外,吸收体8的与腰部褶裥3R重叠的重叠部8C的宽度方向的长度短于比该重叠部8C靠下裆侧的部位8D的宽度方向的长度。在此,重叠部8C是在吸收体8中与线状橡胶4R3重叠的部位,下裆侧的部位8D是比重叠部8C靠下裆区域1B侧的部位。通过采用这样的形状的吸收体8,重叠部8C的宽度方向的端部向宽度方向内侧收缩,容易形成保持粪便的空间。Moreover, the length of the width direction of the overlapping part 8C which overlaps with 3R of waist gathers of the absorber 8 is shorter than the length of the width direction of the site|part 8D on the crotch side rather than this overlapping part 8C. Here, the overlapping portion 8C is a portion overlapping the linear rubber 4R3 in the absorber 8 , and the crotch-side portion 8D is a portion closer to the crotch region 1B than the overlapping portion 8C. By adopting the absorber 8 of such a shape, the end portion in the width direction of the overlapping portion 8C is shrunk inward in the width direction, and a space for holding feces is easily formed.

另外,如图15B所示,在平面观察尿布1的情况下,线状橡胶4R4、4R5的宽度方向的端部与吸收体8重叠,与吸收体8直接或间接地粘接。在此,该端部与吸收体8直接地粘接是指,该端部与吸收体8直接地接合,该端部与吸收体8间接地粘接是指,该端部与吸收体8经由内罩片5R、垫罩片6、背片7接合。在本实施方式中,该端部与吸收体8间接地粘接。假设在比吸收体8靠宽度方向外侧的位置设置有线状橡胶4R4、4R5,吸收体8与线状橡胶4R4、4R5不直接或间接地粘接,则由线状橡胶4R4、4R5产生的伸缩力会在比吸收体8靠宽度方向外侧的位置发挥,无法使该收缩力有助于形成保持粪便的空间。在本实施方式的尿布1中,由于线状橡胶4R4、4R5的宽度方向端部与吸收体8间接地粘接,因此能够使由线状橡胶4R4、4R5产生的伸缩力有助于空间形成。此外,由线状橡胶4R4、4R5产生的伸缩力通过在尿布1的穿戴状态下与尿布1的非穿戴状态相比向宽度方向的外侧拉拽腹部褶裥3T而进行发挥。In addition, as shown in FIG. 15B , when the diaper 1 is viewed in plan, the ends in the width direction of the linear rubbers 4R4 and 4R5 overlap with the absorber 8 and are directly or indirectly bonded to the absorber 8 . Here, the end portion and the absorber 8 are directly bonded means that the end portion is directly bonded to the absorber 8 , and the end portion is indirectly bonded to the absorber 8 means that the end portion and the absorber 8 pass through The inner cover sheet 5R, the cushion cover sheet 6 and the back sheet 7 are joined together. In this embodiment, the end portion is indirectly bonded to the absorber 8 . Assuming that the linear rubbers 4R4 and 4R5 are provided on the outer side of the absorber 8 in the width direction, and the absorber 8 and the linear rubbers 4R4 and 4R5 are not directly or indirectly bonded, the stretching force generated by the linear rubbers 4R4 and 4R5 It is exerted on the outer side in the width direction than the absorber 8 , and the shrinkage force cannot be made to contribute to the space for holding the feces. In the diaper 1 of the present embodiment, since the end portions in the width direction of the linear rubbers 4R4 and 4R5 are indirectly bonded to the absorber 8, the expansion and contraction force generated by the linear rubbers 4R4 and 4R5 can contribute to space formation. In addition, the stretching force by the linear rubbers 4R4 and 4R5 is exerted by pulling the abdomen gathers 3T outward in the width direction in the wearing state of the diaper 1 compared to the non-wearing state of the diaper 1 .

另外,如上所述,通过线状橡胶4F4、4F5向宽度方向的外侧拉拽尿布1的力,从而尿布1的前身区域1F侧的区域向非皮肤面侧呈拱顶状鼓起,形成有积存尿的空间。另外,通过线状橡胶4R4、4R5向宽度方向的外侧拉拽尿布1的力,从而尿布1的后身区域1R侧的区域向非皮肤面侧呈拱顶状鼓起,形成有保持粪便的空间。在有助于这些空间形成的力的影响下,在尿布1的下裆区域1B侧的区域中也是,一对槽8SL、8SR之间容易从穿戴者的皮肤面离开,向非皮肤面侧鼓起。In addition, as described above, by the force of the linear rubbers 4F4 and 4F5 pulling the diaper 1 outward in the width direction, the region on the front body region 1F side of the diaper 1 bulges in a dome shape toward the non-skin surface side, and a pool is formed. space for urine. In addition, by the force of the linear rubbers 4R4 and 4R5 pulling the diaper 1 to the outer side in the width direction, the region on the back body region 1R side of the diaper 1 bulges in a dome shape toward the non-skin surface side, and a space for holding feces is formed. . Under the influence of the forces that contribute to the formation of these spaces, even in the region on the crotch region 1B side of the diaper 1, the pair of grooves 8SL and 8SR easily separates from the wearer's skin surface and bulges toward the non-skin surface side. rise.

此外,关于上述的一对槽8SL、8SR的背侧端部的长度L4、空间的背侧的立起线L5、以及肛门对应区域30的在尿布1的长度方向上的长度L6,不仅适用于本实施方式的尿布1,还适用于第1~第4实施方式的尿布1。In addition, the length L4 of the back side end of the pair of grooves 8SL and 8SR described above, the standing line L5 on the back side of the space, and the length L6 of the anus corresponding region 30 in the longitudinal direction of the diaper 1 are not only applicable to The diaper 1 of the present embodiment is also applicable to the diaper 1 of the first to fourth embodiments.

另外,本实施方式的尿布1除了第3实施方式的尿布1的结构以外,还在比吸收体8靠非皮肤面侧的位置具有用于检测穿戴者的排尿的一对指示器。图16是从皮肤面侧观察指示器的平面图。在图16中,为了说明指示器相对于吸收体8的位置,用虚线表示吸收体8。Moreover, in addition to the structure of the diaper 1 of 3rd Embodiment, the diaper 1 of this embodiment has a pair of indicators for detecting urination of a wearer at the position of the non-skin surface side rather than the absorber 8. Fig. 16 is a plan view of the indicator viewed from the skin surface side. In FIG. 16 , in order to explain the position of the indicator with respect to the absorber 8 , the absorber 8 is indicated by a broken line.

如图16所示,一对指示器16(本申请中所说的“尿检测体”的一例)设置于与吸收体8的非皮肤面侧的表面相对的、背片7的皮肤面侧的表面。指示器16配置于尿布1的宽度方向的中心部,以下裆区域1B为中心在尿布1的长度方向上延伸。另外,指示器16配置成从背片7的宽度方向的两侧被背片7中的与吸收体8的一对槽8SL、8SR对应的部位夹着。也就是说,可以说一对槽8SL、8SR配置成从吸收体8的宽度方向的两侧夹着吸收体8中的与一对指示器16对应的部位。指示器16例如通过将配合有硝嗪黄、溴麝香草酚蓝等因水分的pH的变化而变色的pH指示剂的热熔胶等粘接剂涂布于背片7而形成。另外,指示器16例如也可以通过将配合有二氧化硅粉末、硅酸铝粉末等因水分的存在而变色的光散射性粉末的粘接剂涂布于背片7而形成。这些指示器16的颜色在从非皮肤面侧观察尿布1时,即使隔着垫罩片6也能够目视确认。并且,指示器16在穿戴者所排出的尿接触了时,由于尿液的pH、水分而变色,从而检测穿戴者的排尿。由此,本实施方式的尿布1能够将穿戴者的排尿通知给他人。As shown in FIG. 16 , a pair of indicators 16 (an example of the “urine detection body” referred to in the present application) are provided on the skin surface side of the back sheet 7 opposite to the surface on the non-skin surface side of the absorber 8 . surface. The indicator 16 is arrange|positioned at the center part of the width direction of the diaper 1, and is extended in the longitudinal direction of the diaper 1 centering on the crotch region 1B. Moreover, the indicator 16 is arrange|positioned so that it may be pinched|interposed by the site|part corresponding to a pair of groove|channel 8SL and 8SR of the absorber 8 in the back sheet 7 from both sides of the width direction of the back sheet 7. That is, it can be said that a pair of groove|channels 8SL and 8SR are arrange|positioned so that the site|part corresponding to a pair of indicator 16 in the absorber 8 may be pinched|interposed from both sides of the width direction of the absorber 8. The indicator 16 is formed by, for example, applying an adhesive such as a hot-melt adhesive to the back sheet 7 in which a pH indicator, such as nitrazine yellow and bromothymol blue, which changes color due to pH changes of moisture, is blended. Moreover, the indicator 16 can also be formed by apply|coating the adhesive agent mix|blended with the light-scattering powder which changes color by presence of moisture, such as a silica powder and an aluminum silicate powder, to the back sheet 7, for example. The colors of these indicators 16 can be visually recognized even through the pad cover sheet 6 when the diaper 1 is observed from the non-skin surface side. Furthermore, the indicator 16 changes color due to the pH and moisture of the urine when the urine excreted by the wearer comes into contact, and detects the urination of the wearer. Thereby, the diaper 1 of this embodiment can notify others of the wearer's urination.

此外,尿布1也可以代替设置于背片7的指示器16,而设置配置于吸收体8与背片7之间的、含浸有前述的pH指示剂或光散射性粉末的分散体的不透液性的片作为指示器片。In addition, in place of the indicator 16 provided in the back sheet 7, the diaper 1 may be provided with an impermeable impermeable dispersion impregnated with the aforementioned pH indicator or light-scattering powder, which is arranged between the absorber 8 and the back sheet 7. The liquid sheet acts as an indicator sheet.

指示器16设置于背片7中的下裆区域1B侧的区域,而且设置于宽度方向的中心部。另一方面,穿戴者有时在尿布1内出汗。例如,在穿戴者在下裆部出汗的情况下,汗从穿戴者的皮肤通过顶片29而浸入到吸收体8的皮肤面侧的表面中的下裆区域1B侧的部分。特别是,从吸收体8的宽度方向的端部朝向在穿戴状态下成为最低的位置的宽度方向的中心部在吸收体8的皮肤面侧的表面流动同时浸入。另外,在穿戴者在腹部或背部出汗的情况下,汗从吸收体8的皮肤面侧的表面中的前身区域1F侧的区域或后身区域1R的区域朝向在穿戴状态下成为比该部分低的位置的下裆区域1B侧的区域流动同时浸入。其结果是,指示器16有可能与穿戴者的汗发生反应而导致误检测。由此,有时会产生导致他人更换还能够使用的尿布1或导致他人接触尿布1的内侧来确认尿布1是否还能够使用等不良情况。The indicator 16 is provided in the area|region on the crotch area|region 1B side in the back sheet 7, and is provided in the center part of the width direction. On the other hand, the wearer may sweat in the diaper 1 . For example, when the wearer sweats in the crotch, the sweat penetrates from the wearer's skin through the top sheet 29 to the part on the crotch region 1B side of the surface of the absorber 8 on the skin side. In particular, the absorber 8 penetrates while flowing from the end in the width direction of the absorber 8 toward the center in the width direction, which is the lowest position in the wearing state. In addition, when the wearer sweats on the abdomen or the back, the perspiration from the front body region 1F side or the back body region 1R of the surface of the absorber 8 on the skin side is larger than the region in the wearing state. The region on the crotch region 1B side of the low position flows while soaking. As a result, the indicator 16 may react with the sweat of the wearer, resulting in erroneous detection. As a result, there may be problems such as the replacement of the diaper 1 which is still usable by another person, or the confirmation of whether the diaper 1 is still usable by the other person touching the inner side of the diaper 1 .

但是,在本实施方式的尿布1中,一对槽8SL、8SR配置成从吸收体8的宽度方向的两侧夹着吸收体8中的与指示器16对应的部位。由此,如以下那样,穿戴者的汗在吸收体8的皮肤面侧的表面流动。However, in the diaper 1 of this embodiment, a pair of groove|channel 8SL and 8SR is arrange|positioned so that the part corresponding to the indicator 16 in the absorber 8 may be pinched|interposed from both sides of the width direction of the absorber 8. Thereby, as follows, the sweat of the wearer flows on the surface of the absorber 8 on the skin surface side.

图17是说明吸收体8的皮肤面侧的表面中的穿戴者的汗的流动的图。在图17中,为了说明指示器16相对于吸收体8的位置,用虚线表示指示器16。另外,在图17中,用虚线的矩形表示吸收体8中的积存尿的空间以及保持粪便的空间。此外,图17中的这些空间的形状是例示,不限于矩形状。FIG. 17 is a diagram illustrating the flow of the wearer's sweat on the surface of the absorber 8 on the skin side. In FIG. 17 , in order to explain the position of the indicator 16 with respect to the absorber 8 , the indicator 16 is indicated by a broken line. In addition, in FIG. 17 , the space in which the urine is stored and the space in which the feces are retained in the absorber 8 are indicated by the broken-line rectangle. In addition, the shape of these spaces in FIG. 17 is an illustration, and is not limited to a rectangular shape.

如上所述,通过配置有一对槽8SL、8SR,从而如图17中箭头所示,例如关于穿戴者在下裆部出的汗中的比槽8SL、8SR靠宽度方向的外侧的汗,虽然从宽度方向的端部朝向中心部在吸收体8的皮肤面侧的表面流动,但会被槽8SL、8SR阻碍或者进入槽8SL、8SR。由此,关于这样的汗,由于向吸收体8的皮肤面侧的表面中的比槽8SL、8SR靠宽度方向的外侧的区域或向槽8SL、8SR浸入并在那里被保持,因此汗不会浸入到比槽8SL、8SR靠宽度方向的内侧的区域即一对槽8SL、8SR之间的区域。另外,关于穿戴者在腹部或背部出的汗中的比槽8SL、8SR靠宽度方向的外侧的汗也是,虽然从吸收体8的皮肤面侧的表面中的前身区域1F侧的区域或后身区域1R侧的区域朝向下裆区域1B侧的区域流动,但会被槽8SL、8SR阻碍或进入槽8SL、8SR。由此,关于这样的汗也是,汗不会浸入到吸收体8的皮肤面侧的表面中的一对槽8SL、8SR之间的区域。因此,能够抑制指示器16由于汗的水分、pH而发生反应而导致误检测。As described above, by arranging the pair of grooves 8SL and 8SR, as shown by the arrows in FIG. 17 , for example, among the sweat produced by the wearer in the crotch, the sweat on the outer side in the width direction than the grooves 8SL and 8SR varies from the width to the width. The end portion of the direction flows toward the center portion on the surface of the absorber 8 on the skin surface side, but is blocked by the grooves 8SL and 8SR or enters the grooves 8SL and 8SR. As a result, such perspiration is impregnated into and retained in the outer surface of the absorber 8 on the skin side than the grooves 8SL and 8SR in the widthwise direction or into the grooves 8SL and 8SR, so that the perspiration does not occur. It penetrates into the area|region which is the inner side of the groove|channel 8SL and 8SR in the width direction, ie, the area|region between a pair of groove|channels 8SL and 8SR. In addition, the sweat on the outer side in the width direction from the grooves 8SL and 8SR among the sweat on the abdomen or the back of the wearer is the same, although from the area on the front body area 1F side or the back body of the surface on the skin side of the absorber 8 The region on the side of the region 1R flows toward the region on the side of the crotch region 1B, but is blocked by the grooves 8SL and 8SR or enters the grooves 8SL and 8SR. Thereby, also regarding such sweat, sweat does not penetrate into the area|region between a pair of groove|channels 8SL and 8SR in the surface of the absorber 8 on the skin surface side. Therefore, it is possible to prevent the indicator 16 from reacting with the moisture and pH of sweat, resulting in erroneous detection.

另外,在本实施方式的尿布1中,通过将线状橡胶4F4、4F5以伸长状态配置于一对槽8SL、8SR的腹侧端部的尿布1的宽度方向的外侧,从而在吸收体8的前身区域1F侧的区域形成积存尿的空间S1。而且,通过将线状橡胶4R5以伸长状态配置于一对槽8SL、8SR的背侧端部的尿布1的宽度方向的外侧,从而在吸收体8的后身区域1R侧的区域形成保持粪便的空间S2。通过形成有这些空间S1、S2,从而如图17中箭头所示,关于穿戴者在腹部或背部出的汗中的比槽8SL、8SR靠宽度方向的内侧的汗,在从吸收体8的皮肤面侧的表面中的前身区域1F侧的区域或后身区域1R侧的区域朝向下裆区域1B侧的区域流动时,或者直接进入这些空间S1、S2。由此,关于这样的汗,向吸收体8的皮肤面侧的表面中的与这些空间对应的区域浸入并在那里被保持。而且,关于不会浸入到与空间S1、S2对应的区域而从空间S1、S2流出的汗,被槽8SL、8SR引导而进入槽8SL、8SR。由此,关于这样的汗,向吸收体8的皮肤面侧的表面中的槽8SL、8SR浸入并在那里被保持。因此,汗不会浸入到一对槽8SL、8SR之间的区域,能够进一步抑制指示器16进行误检测。Moreover, in the diaper 1 of this embodiment, by arranging the linear rubbers 4F4 and 4F5 in an extended state on the outer side in the width direction of the diaper 1 at the abdominal end of the pair of grooves 8SL and 8SR, the absorber 8 The area on the side of the precursor area 1F of , forms a space S1 for storing urine. Furthermore, by arranging the linear rubber 4R5 in an extended state on the outer side in the width direction of the diaper 1 at the back side ends of the pair of grooves 8SL and 8SR, the area on the back body area 1R side of the absorber 8 is formed to retain excrement. space S2. By forming these spaces S1 and S2, as shown by the arrows in FIG. 17 , the perspiration on the inner side in the width direction than the grooves 8SL and 8SR among the sweat produced by the wearer on the abdomen or the back is found in the skin of the absorber 8 from the skin of the absorber 8 . When the area on the side of the front body region 1F or the area on the side of the back body region 1R of the surface on the face side flows toward the area on the side of the crotch region 1B, or directly enters these spaces S1 and S2. Thereby, such sweat penetrates into the area|region corresponding to these spaces among the surface of the absorber 8 on the skin surface side, and is held there. Furthermore, the sweat flowing out of the spaces S1 and S2 without infiltrating into the regions corresponding to the spaces S1 and S2 is guided by the grooves 8SL and 8SR and enters the grooves 8SL and 8SR. Thereby, such sweat penetrates into the grooves 8SL and 8SR in the surface of the absorber 8 on the skin surface side, and is held there. Therefore, sweat does not penetrate into the region between the pair of grooves 8SL and 8SR, and it is possible to further suppress erroneous detection by the indicator 16 .

另外,在本实施方式的尿布1中,通过使得槽8SL、8SR各自的中心线彼此的间隔W为20mm以上且50mm以下,从而在尿布1的前身区域1F侧的区域、后身区域1R侧的区域形成有与婴幼儿对应的积存尿的空间S1、保持粪便的空间S2,进而,随着这些空间S1、S2的形成,在尿布1的下裆区域1B侧的区域中,一对槽8SL、8SR之间的区域也向非皮肤面侧鼓起。通过一对槽8SL、8SR之间的区域向非皮肤面侧鼓起,从而设置于背片7的指示器16从穿戴者的皮肤面离开。由此,关于穿戴者在下裆部出的汗中的比槽8SL、8SR靠宽度方向的内侧的汗,汗不易浸入到吸收体8的皮肤面侧的表面中的一对槽8SL、8SR之间的区域。因此,能够进一步抑制指示器16进行误检测。Moreover, in the diaper 1 of the present embodiment, by setting the interval W between the center lines of the grooves 8SL and 8SR to be 20 mm or more and 50 mm or less, the area on the front body region 1F side and the back body region 1R side of the diaper 1 are formed. In the area, a space S1 for storing urine and a space S2 for holding feces are formed corresponding to infants. Further, with the formation of these spaces S1 and S2, in the area on the crotch area 1B side of the diaper 1, a pair of grooves 8SL, The area between the 8SRs also bulged toward the non-skin side. The indicator 16 provided on the back sheet 7 is separated from the skin surface of the wearer as the region between the pair of grooves 8SL and 8SR bulges toward the non-skin surface side. As a result, among the sweat produced by the wearer in the crotch region, the sweat on the inner side of the grooves 8SL and 8SR in the width direction is less likely to permeate between the pair of grooves 8SL and 8SR on the surface of the absorber 8 on the skin side. Area. Therefore, erroneous detection by the indicator 16 can be further suppressed.

<第5实施方式的变形例><Variation of the fifth embodiment>

接着,对第5实施方式的变形例的尿布1进行说明。在第5实施方式的尿布1中,槽8SL、8SR在厚度方向上贯通吸收体8,但本实用新型不限于此。例如,在本变形例的尿布1中,槽8SL、8SR也可以如第2实施方式的尿布1那样形成为非贯通的凹状。另外,凹状的槽也可以仅形成于吸收体8的皮肤面侧的表面或仅形成于吸收体8的非皮肤面侧的表面,或者形成于吸收体8的皮肤面侧及非皮肤面侧这两者的表面。Next, the diaper 1 of the modification of 5th Embodiment is demonstrated. In the diaper 1 of 5th Embodiment, although the groove|channel 8SL and 8SR penetrates the absorber 8 in the thickness direction, this invention is not limited to this. For example, in the diaper 1 of the present modification, the grooves 8SL and 8SR may be formed in a non-penetrating concave shape like the diaper 1 of the second embodiment. In addition, the concave grooves may be formed only on the surface of the absorber 8 on the skin surface side or only on the surface on the non-skin surface side of the absorber 8 , or may be formed on both the skin surface side and the non-skin surface side of the absorber 8 . surface of both.

例如,在吸收体8的皮肤面侧的表面形成有一对凹状的槽的情况下,关于穿戴者出的汗中的比凹状的槽靠宽度方向的外侧的汗,被凹状的槽阻碍或进入凹状的槽。由此,关于这样的汗,汗不会浸入到吸收体8的皮肤面侧的表面中的一对凹状的槽之间的区域。另外,在吸收体8的非皮肤面侧的表面形成有一对凹状的槽的情况下,关于绕到吸收体8的非皮肤面侧的穿戴者的汗中的比凹状的槽靠宽度方向的外侧的汗,被凹状的槽阻碍或进入凹状的槽。由此,关于这样的汗,汗不会浸入到吸收体8的非皮肤面侧的表面中的一对凹状的槽之间的区域。因此,能够抑制指示器16进行误检测。For example, when a pair of concave grooves are formed on the surface of the absorber 8 on the skin side, the sweat on the outer side in the width direction from the concave grooves among the sweat produced by the wearer is blocked by the concave grooves or enters the concave grooves. slot. Thereby, regarding such sweat, sweat does not penetrate into the area between the pair of concave grooves in the surface of the absorber 8 on the skin surface side. In addition, when a pair of concave grooves are formed on the surface of the absorber 8 on the non-skin surface side, the outer side in the width direction relative to the concave grooves in the wearer's sweat that is wrapped around the non-skin surface side of the absorber 8 Sweat is blocked by the concave grooves or enters the concave grooves. Thereby, regarding such perspiration, perspiration does not penetrate into the area|region between a pair of concave grooves in the surface on the non-skin surface side of the absorber 8. Therefore, erroneous detection by the indicator 16 can be suppressed.

这样,对于从穿戴者排泄出的液体中的汗,槽8SL、8SR或凹状的槽能够阻止或引导(控制)其移动。另一方面,如在第1~第4实施方式中说明的那样,对于排泄的量比汗多的尿,槽8SL、8SR或凹状的槽也能够促进(控制)其移动。In this way, the grooves 8SL, 8SR or concave grooves can prevent or guide (control) the movement of sweat in the liquid excreted from the wearer. On the other hand, as described in the first to fourth embodiments, the grooves 8SL, 8SR or the concave grooves can also facilitate (control) the movement of urine that is excreted more than sweat.

另外,在第5实施方式的尿布1中,使用中性的顶片29,但本实用新型不限于此。例如,在本变形例的尿布1中,也可以如第3实施方式的尿布1那样,使用包含pH调整成分的弱酸性的顶片。另外,也可以如第1实施方式的尿布1那样,在中性的顶片29的皮肤面侧追加弱酸性的顶片。通过使得与穿戴者的皮肤抵接的顶片为弱酸性,从而即使发生了如第1实施方式中说明的那样的回流,也能够用顶片的pH调整成分来中和被吸收体8保持着的从穿戴者排泄出的液体中含有的氨等碱成分。因此,能够将穿戴者的皮肤从弱酸性维持为中性,能够抑制产生皮肤问题。Moreover, in the diaper 1 of 5th Embodiment, although the neutral top sheet 29 is used, this invention is not limited to this. For example, in the diaper 1 of this modification, like the diaper 1 of 3rd Embodiment, the weakly acidic top sheet containing a pH adjustment component may be used. Moreover, like the diaper 1 of 1st Embodiment, you may add a weakly acidic top sheet to the skin surface side of the neutral top sheet 29. By making the top sheet in contact with the wearer's skin weakly acidic, even if the backflow as described in the first embodiment occurs, the pH adjusting component of the top sheet can neutralize the absorber 8 and hold it. Alkaline components such as ammonia contained in the fluid excreted by the wearer. Therefore, the wearer's skin can be maintained from weakly acidic to neutral, and the occurrence of skin problems can be suppressed.

在使用了弱酸性的顶片的情况下,通过了该顶片后的汗的pH由于pH调整成分而变化,指示器16有可能由于变化了的汗的pH而发生反应导致误检测。但是,在第5实施方式的尿布1中,通过将一对槽8SL、8SR配置成夹着吸收体8中的与指示器16对应的部位,从而关于穿戴者出的汗中的比槽8SL、8SR靠宽度方向的外侧的汗,汗不会浸入到吸收体8的皮肤面侧的表面中的一对槽8SL、8SR之间的区域。因此,即使在使用了弱酸性的顶片的情况下,也能够抑制指示器16进行误检测。另外,在代替一对槽8SL、8SR(贯通槽)而将一对凹状的槽设置于吸收体8的情况下,也同样能够抑制指示器16进行误检测。When a weakly acidic top sheet is used, the pH of sweat after passing through the top sheet is changed by the pH adjusting component, and the indicator 16 may react with the changed pH of sweat, resulting in erroneous detection. However, in the diaper 1 of the fifth embodiment, by arranging the pair of grooves 8SL and 8SR so as to sandwich the portion corresponding to the indicator 16 in the absorber 8, the ratio of the grooves 8SL and 8SR to the sweat of the wearer is higher than that of the grooves 8SL and 8SR. 8SR is located on the outer side in the width direction, and sweat does not penetrate into the area between the pair of grooves 8SL and 8SR in the surface of the absorber 8 on the skin side. Therefore, even when a weakly acidic top sheet is used, erroneous detection by the indicator 16 can be suppressed. In addition, even when a pair of concave grooves are provided in the absorber 8 instead of the pair of grooves 8SL and 8SR (penetrating grooves), erroneous detection by the indicator 16 can be similarly suppressed.

<其他实施方式><Other Embodiments>

接着,对其他实施方式进行说明。在上述第1~第5实施方式的尿布1中,槽8SL、8SR、槽8TL、8TR或槽8UL、8UR形成为在长度方向上呈直线状延伸,但本实用新型不限于此。例如,在平面观察尿布1的情况下,槽8SL、8SR、槽8TL、8TR或槽8UL、8UR也可以在长度方向的两端部侧以向宽度方向的外侧弯曲的方式延伸。槽8SL、8SR、槽8TL、8TR或槽8UL、8UR只要具有长度方向的成分即可。Next, other embodiments will be described. In the diapar 1 of the said 1st - 5th embodiment, although the groove|channel 8SL, 8SR, the groove|channel 8TL, 8TR or the groove|channel 8UL, 8UR is formed so that it may extend linearly in the longitudinal direction, this invention is not limited to this. For example, when the diaper 1 is viewed in a plan view, the grooves 8SL and 8SR, the grooves 8TL and 8TR, or the grooves 8UL and 8UR may extend to be curved outward in the width direction at both ends in the longitudinal direction. The grooves 8SL and 8SR, the grooves 8TL and 8TR, or the grooves 8UL and 8UR only need to have components in the longitudinal direction.

如以上说明的那样,本公开的目的在于,提供在对穿戴者的皮肤所抵接的片赋予弱酸性的性质的情况下防止该性质被从穿戴者排泄出的液体损害的吸收性物品。As described above, an object of the present disclosure is to provide an absorbent article which prevents the property from being damaged by the liquid excreted from the wearer when the weakly acidic property is imparted to the sheet against which the wearer's skin is in contact.

并且,根据本公开,通过由在第1片及第2片中的一方的片中朝向另一方的片突出的突出部隔开间隔地在多个部位支承平坦的另一方的片而在第1片与第2片之间形成有空间,或者使吸收体具有在吸收体的厚度方向上贯通的贯通孔,由此,能够在对穿戴者的皮肤所抵接的片赋予弱酸性的性质的情况下防止该性质被从穿戴者排泄出的液体损害。Furthermore, according to the present disclosure, by supporting the flat other sheet at a plurality of locations at intervals by the protrusions protruding toward the other sheet among the first sheet and the second sheet, the first sheet and the second sheet When a space is formed between the sheet and the second sheet, or the absorber has a through hole penetrating in the thickness direction of the absorber, a weakly acidic property can be imparted to the sheet against which the wearer's skin is in contact. This prevents this property from being compromised by fluids excreted from the wearer.

另外,本公开的其他目的在于,提供抑制由于尿以外的穿戴者的体液而导致尿检测体误检测的吸收性物品。In addition, another object of the present disclosure is to provide an absorbent article that suppresses erroneous detection of a urine sample due to a wearer's body fluid other than urine.

并且,根据本公开,由于具备沿着吸收体的长度方向设置于吸收体、且以从吸收体的宽度方向的两侧夹着吸收体中的与尿检测体对应的部位的方式配置的一对槽,因此能够抑制由于尿以外的穿戴者的体液而导致尿检测体误检测的情形。In addition, according to the present disclosure, the pair is provided on the absorber along the longitudinal direction of the absorber and arranged so as to sandwich the portion corresponding to the urine test body in the absorber from both sides in the width direction of the absorber. Therefore, it is possible to suppress false detection of the urine sample due to the wearer's body fluids other than urine.
