Description

  The present invention relates to an auxiliary pad and an absorbent article with an auxiliary pad.

  Conventionally, as an absorbent article that absorbs a predetermined liquid such as menstrual blood, an absorbent layer that absorbs the predetermined liquid, a liquid-permeable surface sheet that covers the skin-side surface of the absorbent layer, and a clothing side of the absorbent layer An absorbent article having a liquid-impermeable back sheet covering the surface and formed into a sheet shape as a whole can be exemplified. Such a substantially sheet-like absorbent article is used in a state of being in contact with the excretion opening of a predetermined liquid such as menstrual blood, and directly absorbs the predetermined liquid such as menstrual blood from the excretion opening, Various measures have been made to prevent menstrual blood flowing along a predetermined groove or the like from adhering to clothes or the like.

  For example, as a means to prevent menstrual blood leakage, wings are provided on both sides of the absorbent article so as to protrude in the width direction, and the wing is folded back to the underwear side to fix the absorbent article, or a menstrual excretion part There exists a thing which absorbs menstrual blood by making a nearby absorber rise to the excretion opening side, and making an absorber adhere to an excretion part. However, even in these absorbent articles, there are cases where it is not possible to suitably follow the movement of the body or the change in the shape of the body surface.

On the other hand, a lower absorbent body fixed to the main body portion of the absorbent article and an absorbent article provided with an upper absorbent body separately from the lower absorbent body, and sandwiched between the upper absorbent body and the lower absorbent body. Thus, an absorbent article has been proposed in which the intermediate sheet having elastic elasticity arranged in the longitudinal direction pushes the upper absorbent body into close contact with the body and has improved followability to the excretion site (for example, Patent Documents) 1).
JP 2000-152957 A

  However, in the absorbent article in Patent Document 1, the upper absorbent body is generally fixed along the longitudinal direction to the lower absorbent body of the sanitary napkin and is fixed in the width direction at both ends of the lower absorbent body. In addition, the top surface is wide and flat in the width direction when mounted. For this reason, since a predetermined space is generated between the upper absorbent body and the groove in the body, the upper absorbent body cannot abut on the excretion part at the back of the body groove and cannot be tightly contacted. Leakage may occur.

  Furthermore, if the upper absorbent body is a slight movement in the lateral direction of the body, the upper absorbent body can follow the body side by deforming, but the body or the It cannot follow the movement of the underwear, the body in the vertical direction or the movement of the underwear.

  In addition, since the upper absorbent body is generally fixed to the lower absorbent body along the longitudinal direction, when the sanitary napkin is attached to the underwear, the upper absorbent body is attached at a position where the user cannot see it. It is not always possible to wear the upper absorbent body so that it always adheres well to the groove of the body. When the upper absorbent body cannot be mounted so as to be in close contact with the groove of the body, a predetermined space is formed between the upper absorbent body and the excretion opening, which may cause leakage.

  This invention is made | formed in view of the above subjects, and makes it a subject to provide the auxiliary pad provided with the absorber which can track a body side.

  In order to achieve the above object, the present inventor can arrange the auxiliary pad that is fixed to one surface side of the base absorbent article in the usage mode to facilitate the contact of the auxiliary pad near the body excretion opening.

[1] Overall structure of sanitary napkin with auxiliary pad The overall structure of the auxiliary pad 3 and the sanitary napkin 1 with the auxiliary pad according to the first embodiment of the present invention shown in FIGS. 1 to 13 will be described.

[1.1] General As shown in FIGS. 1 to 13, a sanitary napkin 1 with an auxiliary pad, which is an absorbent article with an auxiliary pad, according to the present embodiment, includes an auxiliary pad 3 and a base napkin that is a base absorbent article. It consists of two.

  The sanitary napkin 1 with an auxiliary pad according to the first embodiment includes an auxiliary pad 3 and a base napkin 2 that is a base absorbent article. Further, the auxiliary pad 3 includes a pad-side absorbent portion 30 that is a pad-side absorbent layer, and a belt-like member 10. Specifically, as shown in FIGS. 1 to 7, the auxiliary pad 3 is provided on a liquid-permeable surface sheet 33 provided on the wearer's skin contact surface side and on the wearer's non-skin contact surface side. A pad-side absorber 30 having a liquid-permeable back sheet 34 provided, and a liquid-retaining pad-side absorber 35 that is disposed between the top sheet 33 and the back sheet 34 and constitutes an absorption layer; A liquid permeable belt-like member 10 provided on the non-skin contact surface side of the back sheet 34 and disposed along the longitudinal direction of the absorbent article body on the other side in the thickness direction of the absorbent article body; Is provided.

  The pad side absorption part 30 and the strip | belt-shaped member 10 are joined in the junction part 8 provided in the one end side in a longitudinal direction. Specifically, the belt-like member 10 is joined to the back sheet 34 at the joining portion 8 with a joining material. That is, the belt-like member 10 is joined to the back sheet 34 at one end of the belt-like member 10 at a predetermined position in the front region F of the pad-side absorbent portion 30. The other end side of the belt-like member 10 becomes a free end 10r extending along the longitudinal direction of the pad-side absorbent portion 30 in the rear region R with the joint portion 8 as a base point. Here, the front region F refers to a region in contact with the wearer's vaginal opening from the vaginal opening to the abdomen when the sanitary napkin 1 with the auxiliary pad is worn, and the rear region R described later refers to the sanitary device with the auxiliary pad. The area | region which contacts a buttocks side from a wearer's vagina opening at the time of wearing the napkin 1 is said. Moreover, a center area shall mean the area | region which contact | connects the excretion part vicinity including a wearer's vaginal opening at the time of wearing the sanitary napkin 1 with an auxiliary pad.

  In the present embodiment, the bonding portion 8 is formed by bonding the pad side absorption portion 30 and the belt-shaped member 10 with a bonding material, but may be bonded by pressure bonding or the like.

  The free end 10r side of the band-like member 10 extends from the outer edge of the end of the pad side absorbing portion 30 in the longitudinal direction, and a gripping portion 40r is provided at the extended portion. On the non-skin contact surface side on the free end 10r side, and on the non-skin contact surface side of the band-like member 10 in the joint portion 8, the pad side that is locked with the underwear 55, the base napkin 2 or the like that is the locked body Locking portions 37f and 37r are provided, respectively.

[1.2] Pad Side Absorbing Part As shown in FIGS. 1 to 3, the pad side absorbing part 30 is formed in a substantially vertically long shape. Examples of the shape of the pad-side absorbent portion 30 include a rectangle, an ellipse, and a bowl. In the present invention, any shape that matches the shape of the wearer's body and the underwear 55 may be used. The length in the longitudinal direction of the pad-side absorbent portion 30 is preferably, for example, 100 mm to 300 mm, and more preferably 150 mm to 250 mm. The length in the width direction is preferably, for example, 30 mm to 150 mm, more preferably 40 mm to 100 mm.

  The pad side absorber 30 includes a pad side absorber 35. Excrements such as menstrual blood excreted from the excretion portion permeate the top sheet 33 and are absorbed by the pad side absorber 35. The back sheet 34 disposed on the non-skin contact surface side is preferably formed of a liquid-permeable nonwoven fabric. When the pad-side absorbent body 35 cannot absorb the excrement such as menstrual blood due to the liquid permeability, the excrement such as menstrual blood is transferred to the base napkin 2 described later, and the base napkin 2 is transferred. Can be absorbed.

  Here, the surface sheet 33 and the pad side absorber 35 are joined so that each is bonded together by a hot melt adhesive. Further, a pad-side absorbent body 35 is wrapped by the top sheet 33 and the back sheet 34, and both side portions thereof are formed by hot melt adhesive, thermocompression bonding, or the like along the longitudinal direction of the pad-side absorbent portion 30 (not shown). It is also possible to perform bonding by bonding them together. As a whole, the surfaces of the sheets are bonded to each other with a hot melt adhesive, and the end portions of the sheets are bonded by a bonding portion (not shown) formed by a thermocompression treatment.

Examples of the coating pattern for hot melt bonding include spiral coating, control seam coating, coater coating, curtain coater coating, and summit gun coating. The basis weight of the adhesive in hot melt bonding is preferably 1 g / m ² to 30 g / m ² , and more preferably 3 g / m ² to 10 g / m ² . In the case of a pattern in which the adhesive is coated in a linear shape, the wire diameter is preferably 30 μm to 300 μm.

[1.3] Band-shaped member As shown in FIGS. 2 to 7, the band-shaped member 10 is formed in a substantially vertically long shape. As shown in FIG. 3 or 4, the band-shaped member 10 sandwiches a plurality of elastic members 12 formed in a thread shape between a pair of band-shaped base sheets 11 and 13, and bonds the base sheets 11 and 13 together. Is formed. Specifically, first, by applying a predetermined tension in the longitudinal direction of the elastic material 12, the elastic material 12 is stretched to a predetermined length, and the stretched elastic material 12 is made of the base sheet 11, 13. It is formed by sandwiching.

As the base material sheets 11 and 13, for example, a spunbonded nonwoven fabric mainly composed of polypropylene (PP) can be used. In this case, the basis weight is preferably 15 g / m ² to 25 g / m ² . The fineness is preferably 1.5 dtex to 2.5 dtex. For example, urethane elastic yarns can be used as the elastic material 12. The fineness of the elastic yarn is preferably 350 dtex to 450 dtex. For example, 7 to 9 elastic yarns can be used (FIG. 5).

  Next, the elastic material 12 in such a stretched state is sandwiched between the base material sheets 11 and 13 to bond the elastic material 12 and the base material sheets 11 and 13 respectively, and then the tension applied to the elastic material 12 in advance is applied. The extension of the elastic material 12 is released by releasing. The elastic material 12 contracts by the cancellation of the stretching, but the base material sheets 11 and 13 are formed with a length corresponding to the stretched elastic material 12, so that a predetermined extension margin is formed on the base material sheets 11 and 13. The Thereby, the strip | belt-shaped member 10 becomes extensible. Here, the extension includes slack and slack that occur in the base material sheets 11 and 13 when the elastic force of the elastic member 12 is released. The belt-like member 10 can be expanded and contracted by the amount of the slack. And since the belt-like member 10 is configured to sandwich the elastic material 12 between the base material sheets 11 and 13 which are non-stretchable materials, for example, when the elastic member or the like is stretched, the substantially central portion becomes narrow. It becomes possible to prevent so-called neck-in.

  As another stretching process that enables stretching, for example, a slit process may be partially performed, but a wavy embossing process may be preferably performed. In the wavy embossing process, for example, stretchability can be imparted by forming the wavy shape by interleaving the base sheet 11 or 13 between the wavy embossing rolls, so that the band-shaped member 10 can be formed relatively easily. Because. Further, the band-like member 10 may be formed by being sandwiched between the base material sheets 11 and 13 in a state where the elastic material 12 is stretched when being wavy embossed, or sandwiched in a state where it is not stretched. May be formed.

  FIG. 6 and FIG. 7A are specific examples in which wavy embossing is performed. As shown in FIG. 6 and FIG. 7A, the wave-like embossing is a wave pattern having continuous irregularities in the longitudinal direction continuously in the width direction. Examples are 5 mm to 5.0 mm. Moreover, the height of a convex part can illustrate 0.5 mm to 5.0 mm, for example. The clearance between the convex side surfaces in the bitten state can be exemplified from 0 mm to 3.0 mm.

  The band-shaped member 10 formed as described above can easily set the extension range. For example, when the stretch range is 130%, when the wearer pulls the belt-shaped member 10 in a stretched state of 130%, an excessive force is required beyond that, so the belt-shaped member 10 becomes difficult to pull. As a result, the wearer can easily recognize the extension range. Thus, anyone can wear in a stable range regardless of the wearer by setting the extension range.

  For example, the extension range can be set by joining the base sheet 11 or 13 with the extension range set to 130% in FIG. 5, and in FIG. 6, the extension range is designed by the uneven shape of the wavy emboss. May be.

  Further, in the method of forming the extension shown in FIGS. 5 and 7A, the extension margin is irregularly formed. Therefore, as shown in FIG. The embossing can be exemplified by an embossing pattern in which a wavy pattern having repetitive unevenness in the longitudinal direction of the material sheets 11 and 13 has a portion of a portion 101 (a portion having no unevenness) in the width direction. Specifically, in addition to the embossed pattern shown in FIG. 5, there can be exemplified a pattern in which nuclides 101 having a width of 5 to 40 mm and a width of 0.5 to 3.0 mm are provided in the width direction. As another example, the hot melt may be applied to the base material in a coating pattern that repeats coating in the width direction and repeatedly coating and non-coating in the longitudinal direction. Thereby, regular wrinkles can be prevented.

  In the present embodiment, the non-stretched material is used as the base sheet 11, 13, but the present invention is not limited to this, and for example, a stretched material or a stretchable material may be used. Moreover, in this embodiment, although the strip | belt-shaped member 10 was comprised by the base material sheets 11 and 13 and the elastic material 12, in this invention, it is only based on the base material sheet which has not only this but a stretching property. Also good. For example, a fibrous sheet using a thermoplastic elastomer resin may be used. Specifically, a non-woven fabric in which urethane fiber and synthetic fiber are mixed, a non-woven fabric including a layer obtained by molding an elastomer resin with a melt blown, or a film sheet can be exemplified.

  The elastic material 12 does not need to be provided in all regions of the base material sheets 11 and 13 and may be provided in at least a part. For example, it is also possible to form the base material sheets 11 and 13 only at the location where the locking material to be locked with the underwear 55 or the base napkin 2 is provided, and to sandwich the elastic material 12 in other regions. Good. Further, it is not necessary to hold the elastic material 12 in a region constituting the gripping portion 40r described later, and the configuration may be configured by only the base material sheets 11 and 13.

  The band-shaped member 10 only needs to have a stretchable region at least in a part in the longitudinal direction, and preferably, when the pad-side absorbent portion 30 is stretchable at a position where it is in close contact with the excretion portion when worn. Good. More preferably, the pad-side absorbent portion 30 may be in a state where it can be expanded and contracted at a position where it is in close contact with the vaginal opening. That is, the structure which has a non-expanding-contraction area | region in a part of longitudinal direction at the time of mounting | wearing may be sufficient. For example, in the region where the back sheet 34 and the belt-like member 10 are joined, and in the region where the pad-side absorbent portion 30 or the belt-like member 10 is locked with the underwear 55, the base napkin 2, etc., there is no elasticity. It may be stretchable in other regions. In the joint part 8 that joins the back sheet 34 and the belt-like member 10, and the pad-side absorbing part 30 or the pad-side latching parts 37 f and 37 r that latch the belt-like member 10 and the undergarment 55 or the base napkin 2, they expand and contract. It is preferable that the structure has no property. This is because joining or locking by the bonding material for bonding the back sheet 34 and the band-shaped member 10 and the locking material for locking the band-shaped member 10 to the undergarment 55, the base napkin 2 or the like is difficult to be released. .

  For example, the non-stretchable region may be formed by joining the elastic material 12 and the base material sheets 11 and 13 in a state where the elastic material 12 is not stretched. Alternatively, the elastic material 12 in an extended state may be cut to release a predetermined elastic force. Furthermore, you may form by joining the extensible area | regions produced by embossing etc. In addition, the base material sheets 11 and 13 themselves may be non-stretchable sheets without forming the stretchable region such as corrugated embossing on the base material sheets 11 and 13.

  The length in the width direction of the belt-like member 10 is preferably, for example, in the range of 30% to 150% of the length in the width direction of the pad side absorbent portion 30, and more preferably in the range of 60% to 130%. If it is smaller than 30% of the length in the width direction of the pad side absorbent portion 30, for example, the entire pad side absorbent portion 30 cannot be pulled up sufficiently, and the entire pad side absorbent portion 30 is brought into close contact with the body side. It is because it cannot be done. On the other hand, if it is larger than 150%, the area in contact with the wearer's thigh becomes excessive, and there is a risk of causing skin troubles by rubbing with the thigh.

  Moreover, the length in the longitudinal direction of the belt-shaped member 10 is preferably in the range of 30% to 300% of the length in the longitudinal direction of the pad side absorbent portion 30, and more preferably in the range of 70% to 150%. it can. This is because, if the length of the pad side absorbent portion 30 is smaller than 30% of the length in the longitudinal direction, for example, even if the belt-like member 10 is stretched, the pad side absorbent portion 30 cannot be sufficiently adhered to the body side. On the other hand, if it is larger than 150%, the area in contact with the wearer's thigh becomes excessive, and there is a risk of causing skin troubles by rubbing with the thigh. Further, for example, the belt-like member 10 may not be attached to the underwear 55 or the base napkin 2 in a stretched state, and may not be brought into close contact with the excretory part.

  The stretchable range of the belt-like member 10 is preferably in the range of 105% to 300%, more preferably in the range of 110% to 180%, for example, when the non-stretched state of the elastic material 12 is 100%. . This is because if the stretched state is smaller than 105%, the stress that pushes the pad-side absorbent portion 30 toward the body becomes weak, and it may not be possible to sufficiently adhere to the excretory portion. Moreover, when larger than 300%, it is because the push-up force to the body side generate | occur | produces more than necessary, and there exists a possibility of giving a wearer a discomfort. Furthermore, the stress of the elastic member 12 when the stretched state is 105% to 300% is preferably in the range of, for example, 5 cN / 25 mm to 500 cN / 25 mm, and more preferably 20 cN / 25 mm to 100 cN / 25 mm. A range is preferable.

  The belt-like member 10 has a gripping portion 40r at a free end 10r which is the other end side opposite to the one end side joined to the pad side absorbing portion 30 in the longitudinal direction. The grip portion 40r is provided on the other end side so as to extend from the outer edge of the pad-side absorbent portion 30. Thereby, a wearer becomes possible [recognizing the strip | belt-shaped member 10 easily], for example, and it becomes possible to prevent the erroneous wear at the time of wear. The gripper 40r only needs to be extended to the extent that the wearer can pick it up with a finger or the like. Further, as shown in FIG. 4C, the gripping portion 40r is formed by attaching the sheet member 14 having a predetermined strength at a position corresponding to the gripping portion 40r of the belt-like member 10 so that the wearer can easily pick it. 13 may be held between them. Note that the gripping portion 40r is preferably a non-stretched region.

  In addition, a guide element indicating a predetermined operation or the like can be disposed on the grip portion 40r. Specifically, the indicator 41r, which is a guide element, can be arranged in a visible manner. The indicator 41r, which is a guide element, can be directly printed on the gripping portion 40r, and the gripping portion 40r may be made of an SMS nonwoven fabric having a color different from that of the auxiliary pad 3.

  For example, the indication mark 41r may be a display that prompts the user to pinch the grip 40r and pull it in a predetermined direction in the longitudinal direction. For example, it may be a combination of an arrow pointing outward in the longitudinal direction, a point indicating a pinching point, or a predetermined color that suggests pulling the grip portion 40r in the longitudinal direction. The form of the indicator 41r can be arbitrarily selected.

[1.4] Joining Position of Pad-Side Absorbing Part and Strip Member The pad-side absorbent part 30 and the strip member 10 are joined at the joint 8. As a joining position of the strip-shaped member 10 with respect to the pad side absorption part 30, when attaching the auxiliary pad 3, it is preferable to arrange | position to the front area | region F rather than a wearer's vaginal opening. For example, it is preferable to be provided in a raised portion in the vicinity of the wearer's excretion portion. Specifically, the position corresponding to the pubic bone in the vicinity of the vaginal opening is preferable. This is because the position corresponding to the pubic bone is harder and slightly raised than the surrounding area, so that the pressure received from the undergarment 55 or the base napkin 2 is increased, and the pad-side absorbent portion 30 is less likely to be displaced from the body. Thereby, for example, even if the belt-like member 10 is pulled and stretched at the time of wearing, the pad-side absorbent portion 30 does not shift due to the stress during wearing and during wearing. Further, in the joint portion 8, the sheet member 14 is sandwiched between the base material sheets 11 and 13 in the band-shaped member 10. Thereby, the strip | belt-shaped member 10 in the junction part 8 has predetermined intensity | strength.

[1.5] Packaging Form of Auxiliary Pad As shown in FIG. 8, the auxiliary pad 3 is packaged by a packaging sheet 50 that is a substantially rectangular sheet. And the locking tape 51 is arrange | positioned at one edge part of the longitudinal direction in the one surface side of the packaging sheet 50, Comprising: The one surface side of the width direction substantially center.

  For example, the packaging sheet 50 may be formed of an SMS nonwoven fabric. By forming with SMS nonwoven fabric, when the pad side latching portions 37f and 37r of the auxiliary pad 3 to be described later are made of a hook material, the pad side latching portions 37f and 37r are latched to the packaging sheet 50. The auxiliary pad 3 to be packaged can be fixed. Further, for example, a loop material can be disposed at a predetermined location of the packaging sheet 50, and the pad side locking portions 37f and 37r of the auxiliary pad 3 can be locked and fixed. The auxiliary pad 3 is disposed on the other surface side of the packaging sheet 50.

  Moreover, when the pad side latching | locking parts 37f and 37r are formed with the adhesive material, it is preferable that the surface which arrange | positions the auxiliary pad 3 in the packaging sheet 50 is mold-release-processed. Or the sheet | seat member by which the release process was carried out to a part of surface which arrange | positions the auxiliary pad 3 in the packaging sheet 50 is arrange | positioned in a predetermined position. Then, the release surface of the release-treated sheet member and the adhesive material of the pad side engaging portions 37f and 37r can be opposed to each other so as to be peelable.

  After the auxiliary pad 3 is fixed to the packaging sheet 50, the packaging sheet 50 is folded to the auxiliary pad 3 side together with the auxiliary pad 3 in the order of one folding P and two folding Q as shown in FIG. Lock with the stop tape 51. Furthermore, the side edge in the bent state is sealed by, for example, pressure bonding.

[1.6] Base Napkins Examples of base napkins are described below, but the base napkins are not particularly limited as follows. As the base napkin used in combination with the auxiliary pad 3, a known sanitary napkin or an arbitrary base napkin can be used. For example, as shown in FIG. 8, the auxiliary pad 3 that is individually wrapped can be used by being locked to a known sanitary napkin.

  As shown in FIGS. 9 to 12, the base napkin 2 is, for example, a liquid-impermeable sheet 29 and a base absorbent layer disposed on one surface side of the liquid-impermeable sheet 29, and the auxiliary pad 3 is The central portion 20 to be disposed, and the side portions 21A and 21B which are disposed on both sides of the central portion 20 in the longitudinal direction of the base napkin 2 and whose thickness in the thickness direction of the base napkin 2 is thicker than that of the central portion 20; And wings 23A and 23B formed on both sides in the width direction.

  Also, as shown in FIG. 10, on the back side, which is the other surface, a slip stopper 27 formed at the approximate center in the width direction and a wing side slip stop disposed on the wings formed on both sides in the width direction. Parts 26A and 26B. As described above, the base absorbent layer includes at least the central portion 20 and the side portions 21A and 21B.

  The central portion 20 is a thin region disposed along the longitudinal direction at the approximate center in the width direction of the base napkin 2. Side portions 21A and 21B that are thicker than the central portion 20 are formed on both sides in the width direction of the central portion 20, and a groove portion is formed between the central portion 20 and the side portions 21A and 21B along the longitudinal direction. It is formed.

  The auxiliary pad 3 comes into contact with the body and mainly absorbs the predetermined liquid. In addition, the base napkin 2 also travels through the predetermined liquid that cannot be absorbed by the auxiliary pad 3 and the surface of the auxiliary pad 3. A function of absorbing a predetermined liquid can be provided. That is, it is preferable that the center part 20 is provided with the absorber 200 of predetermined thickness, as shown in FIG. 11, FIG. And the liquid-permeable surface sheet 28 arrange | positioned on the surface of the napkin 2 for bases can further be arrange | positioned as needed. By disposing the liquid-permeable surface sheet 28 on the surface of the base napkin 2, it is possible to improve the touch when the body touches the base napkin 2.

  A liquid-impermeable sheet 29 can be disposed on the surface of the base napkin 2 opposite to the side on which the auxiliary pad 3 is disposed. By disposing the liquid-impermeable sheet 29, it is possible to prevent a predetermined liquid that could not be absorbed by the base napkin 2 and the side portions 21A and 21B from adhering to the undergarment.

  The wings 23 </ b> A and 23 </ b> B are formed such that the liquid-impermeable sheet 29 extends outward in the width direction of the base napkin 2. As shown in FIGS. 9 to 11, wing-side misalignment stoppers 26 </ b> A and 26 </ b> B are provided on the underwear-side surfaces of the wings 23 </ b> A and 23 </ b> B. Then, the entire base napkin 2 can be fixed to the underwear by folding the wings 23A and 23B toward the underwear and attaching the wing side misalignment stoppers 26A and 26B to the underwear.

  Here, the location where the center line in the longitudinal direction of the wings 23A and 23B and the center line in the longitudinal direction of the base napkin 2 intersect is the location where the body excretion site is supposed to abut on the base napkin 2. It is a certain body excretion opening part contact assumption part Z. An example of the distance from the body excretion port part contact assumption portion Z to the front edge 220 that is the front edge in the longitudinal direction is 110 mm. Similarly, the distance to the rear edge 230 can be exemplified by 220 mm.

  The side portions 21 </ b> A and 21 </ b> B are arranged along the longitudinal direction of the base napkin 2 on both sides in the width direction of the central portion 20. The side parts 21A and 21B are arranged in the longitudinal direction so that, for example, one side in the longitudinal direction of the substantially rectangular shape is fixed.

  The side parts 21A and 21B are arranged along the longitudinal direction on both sides of the central part 20, but are arranged in a state of being substantially separated from the central part 20 in the present embodiment. The side portions 21 </ b> A and 21 </ b> B in the present embodiment are fixed to the base napkin 2. The outer end portions in the width direction of the side portions 21 </ b> A and 21 </ b> B may be free ends that are not fixed to the base napkin 2. For example, of the outer end portions in the width direction of the side portions 21A and 21B, only the end portion in the region where the wings 23A and 23B are formed on the outer side in the width direction is the free end, and the other region is the base napkin 2 It may be fixed to.

  As shown in FIGS. 9 and 11, the side portions 21A and 21B are one of a liquid-permeable side surface sheet 212A and 212B and a side surface sheet 212A and 212B arranged so as to cover the side absorption layer. The side part absorbers 213A and 213B that are arranged on the surface and constitute the side part absorption layer, and elastic members 214A and 214B that are arranged along the longitudinal direction of the side parts 21A and 21B are provided.

  Since the side parts 21A and 21B have the side part absorbers 213A and 213B, the side parts 21A and 21B can also absorb liquid. Further, the side portions 21A and 21B are provided with elastic members 214A and 214B so that the free end sides of the side portions 21A and 21B rise in the thickness direction of the base napkin 2 due to the contraction of the elastic members 214A and 214B. It is formed. The height when the free ends of the side portions 21A and 21B stand up in the thickness direction of the base napkin 2 is along the longitudinal direction with the position near the body excretion opening when the base napkin 2 is worn as the apex. It is formed so as to be gently lowered (FIG. 13).

  Further, as shown in FIG. 13, when the base napkin 2 is deformed into a gentle curve, the elastic members 214A and 214B contract and the free ends of the side portions 21A and 21B are raised. Examples of the elastic members 214A and 214B include thread rubber. The elastic members 214A and 214B are preferably fixed with, for example, HMA (hot melt adhesive).

  As described above, the side portions 21A and 21B are formed thicker than the thickness of the central portion 20, and when worn, the side portions 21A and 21B are deformed so that the free end side of the side portions 21A and 21B rises to the body side. It abuts and absorbs a predetermined liquid such as menstrual blood. Note that the side portions 21A and 21B may not be provided. When the side portions 21A and 21B are not provided, it is preferable to arrange a gather that is arranged so as to rise along the longitudinal direction of the central portion 20.

  As shown in FIG. 11, the base napkin 2 can include liquid-impermeable inner edge sheets 210 </ b> A and 210 </ b> B between the central portion 20 and the side portions 21 </ b> A and 21 </ b> B. The inner edge sheets 210A and 210B are disposed between the central portion 20 and the side portions 21A and 21B, respectively, so that they are transmitted through a predetermined liquid that could not be absorbed by the central portion 20 and the surface of the auxiliary pad 3. It is possible to prevent the leakage by blocking the predetermined liquid.

  Furthermore, you may arrange | position the outer edge sheet | seat 211A, 211B also on the opposite side to the side in which the inner edge sheet | seat 210A, 210B is arrange | positioned in the side parts 21A, 21B. By arranging the outer edge sheet 211A, 211B on the outer side in the width direction with each of the side parts 21A, 21B, a predetermined liquid that could not be absorbed by the side parts 21A, 21B or a liquid flowing through the body flows. Thus, adhesion to the undergarment can be suppressed.

  The inner edge sheets 210A and 210B and the outer edge sheets 211A and 211B are arranged so as to rise in the thickness direction. For example, the central part 20 side is made of an SMS non-woven fabric and the opposite side is a film. It is possible to use a sheet formed by bonding these with HMA (hot melt adhesive).

  In addition, the inner edge sheets 210A and 210B and the outer edge sheets 211A and 211B are provided with elastic members at or near the edge arranged on the outer side in the thickness direction which is the free edge side that is not fixed to the base napkin 2. You may arrange. As a member that can be used as the elastic member, for example, thread rubber can be exemplified. And as shown in FIG. 13, it forms so that the free edge side of inner side edge sheet | seat 210A, 210B and outer side edge sheet | seat 211A, 211B may stand up by shrinkage | contraction by this elastic member.

[1.7] Locking means Locking means for locking the base napkin 2, the undergarment 55, etc. and the auxiliary pad 3 is, for example, locking on the auxiliary pad side disposed in the auxiliary pad 3 in this embodiment. Pad-side locking portions 37f and 37r, and base-side locked portions 25f and 25r disposed in the vicinity of the front edge 220 and the vicinity of the rear edge 230 in the central portion 20 of the base napkin 2.

[1.7.1] Locking portions The pad-side locking portions 37f and 37r are arranged on the base napkin 2 contact surface side of the auxiliary pad 3 in the present embodiment, for example. Specifically, the pad side locking portion 37f that is the first locking means is locked to the base napkin 2 in the front region F, and the pad side locking portion 37r that is the second locking means is the rear region. At R, it is locked with the undergarment 55, the base napkin 2, and the like.

  Here, it is preferable that the pad side latching | locking part 37f is provided in the position facing the junction part 8 where the pad side absorption part 30 and the strip | belt-shaped member 10 are joined, for example. In the joint portion 8 between the pad side absorbing portion 30 and the belt-like member 10, it is a starting point with respect to the free end 10r of the belt-like member 10, and is the place where the tension of the belt-like member 10 is most applied to the pad side absorbent portion 30 side. This is because the pad-side absorbent portion 30 is less likely to shift from the undergarment 55. The pad side locking portions 37f and 37r will be described later.

  The pad side locking portion 37r is preferably provided, for example, on the rear region R side in the longitudinal direction of the belt-like member 10, and further preferably slightly on the front side with respect to the rear end on the rear region R side. This is because the body is often greatly curved rearward from the vaginal opening, so that the expansion / contraction range of the belt-like member 10 is expanded by being on the rear side. Moreover, it is because the strip | belt-shaped member 10 expand | extends along the curve of a body, and the stress by the strip | belt-shaped member 10 becomes easy to be transmitted to the pad side absorption part 30 located in the excretion part vicinity. Furthermore, it is because it can prevent a finger | toe etc. from attaching a latching material when a wearer hold | grips the holding | grip part 40 by providing a little forward side rather than the rear end in the rear-end part of the strip | belt-shaped member 10. FIG.

  In order to prevent the belt-like member 10 from being detached from the underwear or the like during wearing, in the case of a belt-like member having stretchability, the locking force by the locking material needs to be larger than the contraction force of the belt-like member 10. is there. Therefore, it is preferable to set the locking force, that is, the shear stress, to be larger than the contraction force in the range of 5 cN / 25 mm to 500 cN / 25 mm.

  Examples of the locking material used for the pad side locking portions 37f and 37r include a hot melt adhesive, a hook material, and an adhesive material. The locking material used for the pad side locking portion 37r provided in the rear region R may be a locking material with the undergarment 55, may be a locking material with the base napkin 2, and is worn. It may be a locking material with the person's body. That is, the locking portion may be locked to the underwear 55 or the base napkin 2 or the like, or may be locked to the wearer's body.

  Specifically, when the pad side locking portions 37f and 37r are formed of an adhesive material, a known adhesive material such as a hot melt adhesive can be used. Moreover, when the pad side latching | locking parts 37f and 37r are formed with a hook material, two types of hook materials can be used, for example. Specifically, a hook material in which a plurality of mushroom-shaped pins are arranged, or a plurality of pins inclined at a predetermined angle so as to be slippery when pulled in one direction and difficult to slip in the other direction are arranged. A hook material having a specific direction can be exemplified.

  Specifically, the hook material in which a plurality of mushroom-shaped pins are arranged has a shape having an umbrella-like cap in which the respective tips of the plurality of pins forming the hook are opened around the pins. The hook material is formed so that the shape of the plurality of pins is a mushroom type as a whole.

  In the case of using a hook material having a plurality of mushroom-shaped pins, examples of a member preferably used as an object to be locked include a member having a fiber that can entangle the mushroom-shaped pins. . Specific examples include nonwoven fabrics, loop materials, and stretchable nonwoven fabrics. Since the hook material having a plurality of mushroom-shaped pins is easily entangled with the fiber in multiple directions, it is difficult to release the plurality of pins entangled with the fiber, and it is difficult to finely adjust the positions of the pad side locking portions 37f and 37r. In some cases or when the locking is released, the locked body may be damaged.

  Examples of the hook material having directionality include a hook material having a directionality that is easy to slip when pulled in one direction and difficult to slide in the other direction. Specifically, the hook material is a hook material in which a plurality of substantially needle-like pins fixed at a predetermined angle with respect to a plane are arranged. More specifically, as shown in FIG. 41, the tip portion 371 of the pin 372 forming the hook material does not have the umbrella-shaped cap as described above, and has a substantially needle shape formed so that the tip is thin. The plurality of pins 372 are formed so as to be inclined at a predetermined angle with respect to the vertical direction from the base sheet 373 serving as the base of the hook material. More specifically, the plurality of pins 372 are arranged so as to form a predetermined angle α from the plane.

  Therefore, the hook material having the directionality shown in FIG. 41 is locked by causing resistance to the force in the direction opposite to the direction in which the plurality of pins 372 are inclined by the plurality of pins 372 being caught by the fibers. The On the other hand, the tip 371 of the pin 372 is bent by the force in the direction in which the plurality of pins 372 are inclined, and is not easily caught by the fiber.

  When a hook material having directionality is used for the pad side locking portions 37f and 37r, the direction in which the plurality of pins 372 are inclined is directed to the front region F, and is opposite to the direction in which the plurality of pins 372 is inclined. The hook material can be arranged as the pad side engaging portion 37r with the direction of the back facing the rear region R. In addition, the hook material disposed in the pad side locking portion 37f is disposed such that the plurality of pins 372 face in the opposite direction to the above.

  When arranged in this way, when the sanitary napkin 1 with the auxiliary pad is mounted, the auxiliary pad 3 is arranged such that the pad side locking portion 37r is on the rear region R side, for example. When the three gripping portions 40r are gripped and pulled up in the R direction (FIG. 15), the hook material is shifted in the direction opposite to the direction in which the plurality of pins 372 are inclined, so the locking is released. It becomes easy to do.

  On the other hand, when the auxiliary pad 3 is fixed at the adjusted position, the auxiliary pad 3 is pulled toward the front edge 220 of the base napkin 2 by the pad side locking portion 37f. Then, the hook material is shifted in a direction in which the plurality of pins 372 are inclined, and thus the hooks are locked.

[1.7.2] Locked portion When the base napkin 2 is flattened, the base side lock is a region where the locking portion 37 of the auxiliary pad 3 abuts in the central portion 20 of the base napkin 2. A locked material suitable for the locking material used in the pad side locking portions 37f and 37r can be disposed in the locking portions 25f and 25r. Specifically, a release film, a loop material, and a nonwoven fabric can be illustrated. By disposing the base side engaged portions 25f and 25r, the engaging material used for the pad side engaging portions 37f and 37r is the top sheet 28 of the base napkin 2 at the initial position where the auxiliary pad 3 is disposed. Can be prevented from being damaged.

  The position where the base-side locked portion 25f is arranged can be exemplified by the position 40 mm forward edge 220 side from the body excretion opening portion contact assumption portion Z in the longitudinal direction of the base napkin 2, for example. Further, the base side engaged portions 25f and 25r can be colored. By being colored, the user can visually recognize the initial arrangement position of the auxiliary pad 3.

  Further, the base-side locked portion 25r can also be arranged at a location where the pad-side locking portions 37f, 37r of the auxiliary pad 3 on the rear edge 230 side in the central portion 20 abut. The base-side locked portion 25r on the rear edge 230 side can exemplify a position on the rear edge 230 side of 130 mm from the body excretion opening portion contact assumption portion Z in the longitudinal direction of the base napkin 2, for example.

  In addition to coloring the base-side locked portions 25f and 25r, the region where the auxiliary pad 3 abuts may also be colored in the central portion 20 of the base napkin 2. By coloring the area, even if the auxiliary pad 3 is removed, the user can visually recognize the position where the auxiliary pad 3 is arranged. Moreover, what is necessary is just the mark which can grasp | ascertain that it is a position which arrange | positions the auxiliary pad 3 besides coloring an area | region. For example, a circle or a star can be exemplified. For example, at least the base-side locked portion 25f can be used as a mark for arranging the auxiliary pad 3 by coloring.

  The members that can be used as the base-side locked portions 25f and 25r can be arbitrarily selected depending on the combination with the members that form the pad-side locked portions 37f and 37r.

  For example, when the pad side latching | locking parts 37f and 37r are formed with the adhesive material, as a member which can be used as the base side latching | locking parts 25f and 25r, a release film can be used, for example.

  In addition, for example, when the pad side locking portions 37f and 37r are formed of the hook material described above, a nonwoven fabric or a loop material can be exemplified.

Specifically, within 20 mm each in the front-rear direction in the longitudinal direction, centering on the body excretion opening portion contact assumption portion Z of the pad-side absorption portion 30K that contacts the vaginal opening of the wearer (40 mm in the longitudinal direction as a whole). It is preferable that More preferably, centering on the body excretion opening part contact assumption portion Z that contacts the vaginal opening of the wearer, the longitudinal direction is 1.0 mm (2.0 mm in the longitudinal direction as a whole) to 10 mm (overall). As an example, a range of 20 mm in the longitudinal direction can be exemplified. If it is larger than 20 mm in each of the longitudinal directions in the longitudinal direction, the area where the stretchability of the band-like member 10K is not exhibited becomes too large, and the pad-side absorbent portion 30K may be easily separated from the excretory portion due to body posture change. Because there is. Further, in the width direction, a range of 10% to 100% in the width direction of the pad side absorbing portion 30K can be exemplified. Preferably, it can illustrate in the range of 60% to 100%. In the width direction, either continuously fixed or intermittently fixed may be used.

  Examples of the bonding material include hot melt adhesive, embossing, sonic processing, and the like. Note that the joint portion 8K may not be provided when the pad side locking portions 37fK and 37r are arranged. That is, the pad side absorbing portion 30K and the belt-like member 10K are separated. Then, the pad-side absorbent portion 30K is disposed on the belt-like member 10K, and the pad-side member 10K holds the pad-side absorbent portion 30K by latching the pad-side engaging portions 37fK, 37r to the underwear 55, the base napkin 2 or the body. You may make it fix by pressing on the body side.

  Further, as shown in FIG. 34, in the twelfth embodiment, the pad side absorbent portion 30L itself may have extensibility in accordance with the extension of the belt-like member 10. Specifically, the extension region S is provided at a substantially central portion of the pad side absorbing portion 30L. A plurality of joint portions (not shown) that are spaced apart from each other can be disposed at both ends of the elongated region S in the longitudinal direction. Specifically, two joint portions can be arranged at both ends in the longitudinal direction of the extension region S. By providing the extension region S between the plurality of joints, the pad-side absorbent portion 30L can be extended. Therefore, the pad-side absorbent portion 30L can be extended in accordance with the extension of the belt-like member 10, and the belt-like member 10 can also be extended in this region.

  Here, the pad side absorbing portion 30L having extensibility will be described. Examples of the pad-side absorbent portion 30L having extensibility include those made of an elastic material. Further, a coiled fiber such as a heat shrinkable fiber may be used. By using an elastic material or a coiled fiber such as a heat-shrinkable fiber, the pad-side absorbent portion 30L can have extensibility.

  As shown in FIG. 35, in the thirteenth embodiment, a plurality of slits 90 having a predetermined cut in the width direction of the pad-side absorbent portion 30M in the elongated region S provided at a predetermined location of the pad-side absorbent portion 30M. By providing the pad side absorbent portion 30M, the pad side absorbent portion 30M may have extensibility. As shown in FIG. 35 (B), the slit 90 is a notch that enters the width direction of the slit 90 when the pad-side absorbent portion 30M has a predetermined stress in each of the front and rear regions F and R in the longitudinal direction. Is opened by being pulled in the longitudinal direction. As a result, the pad-side absorbent portion 30M can extend the opening amount with respect to the longitudinal direction of the slit 90.

[2.8] Fourteenth Embodiment An auxiliary pad 3N according to the fourteenth embodiment of the present invention will be described with reference to FIG. As shown in FIG. 36, the auxiliary pad 3N in the fourteenth embodiment of the present invention is different from the first embodiment in the arrangement of the strip-like member 10.

  As shown in FIG. 36, the auxiliary pad 3N according to the fourteenth embodiment may be provided with a pair of belt-like members 10fN and 10rN extending in the front and rear regions F and R in the longitudinal direction of the pad-side absorbent portion 30N. Good. In this case, it is preferable that the area between the belt-like members 10fN and 10rN is the extension region S in the twelfth and thirteenth embodiments. Further, for example, the strip member 10Nr extending to the rear region R may be configured to use a plurality of strip members 10, 110 as shown in the eleventh embodiment. That is, it is good also as a structure which uses a some strip | belt-shaped member for one or both of strip | belt-shaped member 10fN, 10rN.

[2.9] Fifteenth Embodiment [2.9.1] Overall Configuration A fifteenth embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 37 to 40, the band-shaped member 10P of the auxiliary pad 3P and the bonding mode between the band-shaped member 10P and the pad-side absorbent portion 30P are different from those of the first embodiment.

  The pad-side absorbent portion 30P and the belt-like member 10P are joined at a pair of joint portions 8LP and 8RP provided at a predetermined location in a substantially central portion in the longitudinal direction. Specifically, the joint portions 8LP and 8RP are provided on both sides of the substantially central portion in the longitudinal direction of the auxiliary pad 3P and spaced apart from each other with a predetermined interval across the center in the width direction. The band-shaped member 10P is joined to the pad-side absorbent portion 30P at the joint portions 8LP and 8RP, and is disposed so as to extend along the pad-side absorbent portion 30P in the longitudinal direction in the longitudinal direction starting from the joint portions 8LP and 8RP. .

  Both end portions in the longitudinal direction of the belt-like member 10P extend from outer edges of both end portions of the pad-side absorbent portion 30P in the longitudinal direction, and gripping portions 40fP and 40r are provided in the respective extended portions. On the non-skin contact surface side of each gripping portion 40fP, 40r, pad side locking portions 37fP, 37r that are locked with the underwear 55 or the base napkin 2 as a locked body are provided. Specifically, the pad-side locking portions 37fP and 37r are provided slightly closer to the central portion in the longitudinal direction of the strip-shaped member 10P than the end portions of the strip-shaped member 10P.

[2.9.2] Band-shaped member The band-shaped member 10P is formed in a substantially vertically long shape. The length in the width direction of the belt-like member 10P is preferably, for example, in the range of 30% to 150% of the length in the width direction of the pad side absorbent portion 30P, and more preferably in the range of 60% to 130%. If it is smaller than 30% of the length in the width direction of the pad-side absorbent portion 30P, for example, the entire pad-side absorbent portion 30P cannot be sufficiently lifted, and the entire pad-side absorbent portion 30P is brought into close contact with the body side. This is because they cannot. On the other hand, if it is larger than 150%, the area in contact with the wearer's thigh becomes excessive, and there is a risk of causing skin troubles by rubbing with the thigh.

  Further, the length in the longitudinal direction of the belt-like member 10P is preferably, for example, in the range of 30% to 300% of the length in the longitudinal direction of the pad-side absorbent portion 30P, and more preferably in the range of 70% to 150%. it can. This is because, if the length is smaller than 30% of the length in the longitudinal direction of the pad-side absorbent portion 30P, for example, even if the belt-like member 10P is stretched, the pad-side absorbent portion 30P cannot be sufficiently adhered to the body side. On the other hand, if it is larger than 150%, the area in contact with the wearer's thigh becomes excessive, and there is a risk of causing skin troubles by rubbing with the thigh. Further, for example, the belt-like member 10P may not be attached to the undergarment 55 or the base napkin 2 in a stretched state, and may not be able to adhere to the excretory part.

  Further, the stretchable range of the belt-like member 10P is preferably in the range of 105% to 300%, more preferably in the range of 110% to 180%, where the non-stretched state is 100%. This is because if the stretched state is smaller than 105%, the stress that pushes the pad-side absorbent portion 30P toward the body becomes weak, and the pad-side absorbent portion 30P is hardly lifted. Moreover, when larger than 300%, it is because the push-up force to the body side generate | occur | produces more than necessary, and there exists a possibility of giving a wearer a discomfort. Further, the stress of the strip member 10 when the stretched state is 105% to 300% is preferably in the range of 5 cN / 25 mm to 500 cN / 25 mm, and more preferably in the range of 20 cN / 25 mm to 100 cN / 25 mm. It is preferable that

  The belt-like member 10P is a sheet member that can be extended in the longitudinal direction and can be deformed in the width direction. Note that the belt-like member 10P only needs to be a so-called neck-in (hereinafter referred to as neck-in) that becomes narrower in the width direction when extended in the longitudinal direction. As a range of the neck-in, for example, a range of 20% to 95% can be exemplified when the non-stretched state joined to the pad side absorbent portion 30P is 100%. Preferably, a range of 50% to 80% can be exemplified. As the strip member 10P, for example, a fibrous sheet using a thermoplastic elastomer resin may be used. Specifically, a non-woven fabric in which urethane fiber and synthetic fiber are mixed, a non-woven fabric including a layer obtained by molding an elastomer resin with a melt blown, a film sheet, or the like can be exemplified. In particular, when a fiber assembly is used, the fiber orientation is mainly oriented in the width direction, so that the fiber shape can be easily deformed when stretched in the longitudinal direction, and neck-in can be performed with low load. become.

  The belt-like member 10P includes gripping portions 40fP and 40r in the front region F and the rear region R in the longitudinal direction. The gripping portions 40fP and 40r are provided so as to extend from the outer edge of the pad side absorbing portion 30P at each of both end portions of the belt-like member 10P. Thereby, the wearer can easily recognize the grip portions 40fP and 40r, for example, and can prevent erroneous mounting during mounting. The gripping portions 40fP and 40r need only extend to the extent that the wearer can pick them up with fingers or the like. The gripping portions 40fP and 40r are preferably non-stretched regions.

[2.9.3] Joining Position of Pad Side Absorbing Part and Band-shaped Member The pad side absorbing part 30P and the band-shaped member 10P have a width on each side of the substantially central part of the pad side absorbing part 30P of the auxiliary pad 3P. Joined at joints 8RP and 8LP spaced apart from each other at a predetermined interval across the center in the direction. The substantially central portion of the pad-side absorbent portion 30P in the longitudinal direction is the most necked-in place when the belt-like member 10P is expanded and contracted. The member 10P is preferably joined.

  For example, the distance between the joining portions 8RP and 8LP in the width direction can be exemplified by a range of 5 mm to 200 mm. Preferably, the range of 30 mm to 80 mm can be illustrated. If it is smaller than 5 mm, the pad-side absorbent portion 30P cannot sufficiently rise when the belt-like member 10P necks in. Moreover, when it is larger than 200 mm, the pad-side absorbent portion 30 </ b> P is excessively raised, which may give the wearer a feeling of foreign matter.

  Further, the distance between the bonding portions 8RP and 8LP in the width direction with respect to the length in the width direction of the pad-side absorbent portion 30P may be in the range of 5% to 95%. Preferably, a range of 30% to 80% can be exemplified. If it is smaller than 5%, the pad-side absorbent portion 30P cannot sufficiently rise when the belt-like member 10P is necked in. Moreover, when it is larger than 95%, the pad-side absorbent portion 30P is excessively raised, which may give the wearer a feeling of foreign matter.

  The joining position of the belt-like member 10P in the longitudinal direction with the pad side absorbing portion 30P needs to be joined so as not to sacrifice the extensibility of the belt-like member 10P. For example, if the pad-side absorbent portion 30P and the belt-like member 10P are joined at two locations that are separated from each other in the longitudinal direction, the belt-like member 10P between the joint portions does not stretch, so that the stretchability is No longer occurs. In addition, when the joint portions 8RP and 8LP are arranged long in the longitudinal direction, the pad-side absorbent portion 30P does not expand, and thus the belt-like member 10P does not expand even in that region. Therefore, for example, it is preferable that the joining position is arranged at a place having little influence even if the extensibility of the belt-like member is not exhibited. For example, it is preferable to join in the vicinity of the excretion part of the wearer, specifically, in the vicinity of the wearer's vaginal opening. The pad side absorbing portion 30P does not deform so much in the vicinity of the excretion portion in the longitudinal direction and maintains a substantially straight shape, but starts to bend following the curvature of the body from the front and rear ends of the excretion portion. Thus, even if the extensibility of the belt-like member 10P does not directly act in the vicinity of the excretion portion, the front and rear belt-like members 10 can be extended to lock the pad-side absorbent portion 30. This is because a force acts in a direction in which the pad-side absorbent portion 30P is brought into close contact with the body side.

  For example, the bonding range between the pad-side absorbent portion 30P and the belt-like member 10P, that is, the length of the bonding portion in the longitudinal direction is preferably a position where the wearer's excretion portion can be accommodated. Specifically, it is preferably in the vicinity of the vaginal opening, and more preferably within a range of 20 mm or less to each of the front and rear regions F and R around the substantially central portion of the pad side absorption portion 30P in contact with the vaginal opening. It is preferable to be in the range of 1 mm to 10 mm to each of the front and rear regions F and R. If it is larger than each of the front or rear regions F and R by 20 mm or more, the region where the stretchability of the belt-like member 10P is not exhibited becomes too large, and the pad side absorbent portion 30P can be easily removed from the body depending on the change in the posture of the wearer. This is because there is a risk of leaving.

  Further, in the width direction, a range of 10% to 100% in the width direction of the pad side absorbing portion 30P can be exemplified. Preferably, it can illustrate in the range of 60% to 100%. In the width direction, either continuous and fixed or intermittently fixed may be used. Examples of the fixing material include hot melt adhesive, embossing, and sonic processing.

[2.9.4] Usage Mode A usage mode of the auxiliary pad 3P in the fifteenth embodiment of the present invention will be described with reference to FIG.

  As a usage example of the auxiliary pad 3P according to the present embodiment, a usage mode of a mounting procedure for attaching the auxiliary pad 3P to the undergarment 55 that is a locked body in the mounting process of the auxiliary pad 3P will be described.

  As a usage mode of the mounting procedure, the base napkin 2 is disposed at a predetermined position of the undergarment 55, and the auxiliary pad 3P is further disposed. In this state, the undergarment 55 is pulled up and worn in the body direction. Next, in each of the front and rear regions F and R, a hand is put between the undergarment 55 and the body, the grip portions 40fP and 40r provided on the belt-like member 10P are gripped, and the front and rear portions are along the curvature of the body. Pull in each of regions F and R. Here, for example, in the case where the cover member 15 is provided, when the gripping portions 40fP and 40r are pulled, the pad side locking portions 37fP and 37r provided on the non-skin contact surface side of the belt-like member 10P appear. Then, the underwear 55 or the base napkin 2 is locked at a predetermined position.

  Moreover, the pad side absorption part 30P deform | transforms into convex shape by pulling the strip | belt-shaped member 10P. Specifically, as shown in FIG. 39 (B), when the belt-like member 10P is pulled, the belt-like member 10P becomes narrower at the substantially central portion in the longitudinal direction than at both ends (FIG. 39 (C), ( In order to generate a so-called neck-in), each of the joint portions 8LP and 8RP between the belt-like member 10P and the pad side absorbing portion 30P approaches the width direction. Thus, when each of the joint portions 8LP and 8RP approaches in the width direction, the pad side absorbent portion 30P joined to the belt-like member 10P is projecting and deformed so as to rise to one side (see FIG. 39C). ). Therefore, the deformation amount of the pad-side absorbent portion 30P can be adjusted by adjusting the extension amount of the belt-like member 10P.

  In addition, the usage condition in this embodiment can be used in the state which does not use the strip | belt-shaped member 10P as another usage condition. In this case, it becomes possible to use the belt-like member 10P again after the underwear 55 is worn.

  Moreover, in this embodiment, although the strip | belt-shaped member 10P in the auxiliary pad 3P becomes the aspect extended from the both ends of the front area | region F side and the back area | region R side, only any one has extended, May be bonded to a back sheet 34 (not shown) of the pad-side absorbent portion 30P.

[2.10] Sixteenth Embodiment With reference to FIG. 40, an auxiliary pad 3Q according to a sixteenth embodiment of the present invention will be described. As shown in FIG. 40, the auxiliary pad 3Q according to the sixteenth embodiment of the present invention differs from the first embodiment in the bonding state between the pad-side absorbent portion 30Q and the belt-like member 10Q.

Specifically, as shown in FIG. 40 (A), the auxiliary pad 3Q in the sixteenth embodiment includes the respective joint portions 8RQ, 8RQ in the joint portions 8RQ, 8LQ between the pad side absorbent portion 30Q and the belt-like member 10Q. A connection band 80Q for connecting 8LQ is provided. The band-shaped member 10Q is joined to the connection band 80Q on one end side. As shown in FIG. 40 (B), the other end side of the belt-like member 10Q is pulled in the longitudinal direction, whereby the connecting band 80Q is deformed, and each of the joint portions 8RQ and 8LQ with the connecting band 80Q in the pad side absorbing portion 30Q. Approaches the width direction, and the distance in the width direction of the pad-side absorbent portion 30Q becomes narrower. Thereby, the pad side absorption part 30Q protrudes and deform | transforms into the skin contact surface side.
The connection band 80Q and the band-shaped member 10Q may be formed of the same member or different members. That is, the connection band 80Q and the band-shaped member 10Q may be integrally formed.

  As other embodiments other than the above, the auxiliary pad of the present case is composed entirely of a liquid-permeable material so that menstrual blood can be easily transferred from the auxiliary pad of the present case to a base absorbent body such as another sanitary napkin, Alternatively, a liquid-impermeable material may be used or a liquid passage hole may be partially provided. This is because even if menstrual blood or the like leaks from the auxiliary pad, it can be absorbed by the pad-side absorbent portion 30 used together. Moreover, the strip | belt-shaped member of this case is extended from the absorptive article main body, and also can be utilized as a strip | belt tape for post-processing further, when the latching material is provided.

[3] Each component Each component is described in detail below.

  The top sheet 33 and the back sheet 34 of the auxiliary pad 3 are formed of a resin film having a large number of liquid-permeable holes, a net-like sheet portion having a large number of meshes, a liquid-permeable non-woven fabric, or a woven fabric. As the resin film and the net-like sheet portion, those formed of polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), or the like can be used. Moreover, as a nonwoven fabric, the spunlace nonwoven fabric formed from cellulose fibers, such as rayon, a synthetic resin fiber, the air through nonwoven fabric formed from the said synthetic resin fiber, etc. can be used. Moreover, as a raw material, natural products capable of biodegradability such as polylactic acid, chitosan, polyalginic acid and the like can be used. Further, a large number of liquid permeable holes may be formed, and a silicon-based or fluorine-based water-repellent oil agent may be applied to make it difficult for body fluids to adhere to the outer surface. The same sheet can also be used when the liquid permeable sheet is disposed on the side surface sheets 212A and 212B or the surface of the central portion 20 in the first embodiment.

Also, the basis weight of the topsheet 33 is preferably 80 g / ^{m 2} to 15, particularly preferably 40 g / ^{m 2} to 20, not particularly limited. If the basis weight is 15 g / m ² or less, the surface strength is not sufficiently obtained, and there is a risk of breaking during use. Moreover, in the case of 80 g / m < ² > or more, excessive wrinkle expresses and uncomfortable feeling is produced during use. Furthermore, in the case of long-term use, if it exceeds 80 g / m ² , the liquid is held by the top sheet 33 and is maintained in a solid state, and it becomes uncomfortable. The density is not particularly limited as long as the density is 0.2 g / cm ³ or less and liquid permeability. When the density is higher than this, it is difficult to smoothly transmit between the fibers of the topsheet 33. In the case of menstrual blood, those having a low density are preferred because they are more viscous than urine and the like.

  Moreover, it is preferable that the surface sheet 33 is provided with an opening treatment. It is preferable that the aperture diameter is in the range of 0.5 mm to 10 mm, the pitch is in the range of 1 mm to 15 mm, and the aperture area ratio is in the range of 2% to 20%. As a manufacturing method, the surface sheet 33 obtained by the so-called PFW method in which a film is passed through a pattern drum whose opening conditions have been changed in advance and suctioned by suction, or the PFW method having uniform opening conditions. For example, there may be mentioned a method of further adding an opening to the region straddling the crease line by pin embossing. The arrangement of the apertures is not particularly limited, such as a staggered pattern, a lattice pattern, or a wavy pattern. Examples of the shape of the opening include a round shape, an elliptical shape, and a square shape. Moreover, the valve may be provided in the periphery of the opening part. As the surface sheet 33, a porous or non-porous nonwoven fabric or a porous plastic sheet portion can be preferably used.

  Moreover, as the surface sheet 33 arranged on the skin side opposite to the base napkin 2 side in the auxiliary pad 3, for example, a sheet formed so as to contact the skin at a plurality of points can be used. . When a sheet that contacts the skin at a plurality of points is used as the surface sheet 33, for example, there is a possibility that skin irritation that may occur due to deterioration of air circulation that is likely to occur when the entire surface contacts the skin may be suppressed. .

  Examples of the sheet that comes into contact with the skin at a plurality of points include a sheet having an uneven surface, a sheet having a plurality of openings, and the like. Furthermore, as a sheet | seat in which the surface was formed uneven | corrugated, the sheet | seat which formed the convex part in the porous can be illustrated, for example.

As a suitable example of the topsheet 33, a two-layered fusion sheet in which heat fusion fibers are bonded by means such as air-through can be used. The sheet is composed of hydrophilic fibers and water-repellent fibers having a fiber diameter of 4 denier or less. Specifically, the surface fiber layer is composed of a polyethylene / polyester bicomponent composite fiber, and the back surface fiber layer is composed of polyethylene / polyester or polyethylene / polypropylene bicomponent composite fiber. The basis weight of the sheet is 15 to 80 g / m ² . If the basis weight exceeds 80 g / m ² , the liquid is held by the top sheet 33 and is maintained in a solid state, which makes it uncomfortable.

As a suitable example of the back sheet 34, an SMS nonwoven fabric having a basis weight of 18 g / m ² can be exemplified. With a melt-blown layer made of ultrafine fibers, absorption can be completed only with the auxiliary pad 3 due to its water pressure if it is a small amount of menstrual blood, and it can be transferred to the base napkin 2 if a pressure higher than the water pressure is applied. Although it is preferably a liquid-permeable sheet, a liquid-impermeable sheet may be used. By being a liquid-permeable sheet, a predetermined liquid that cannot be absorbed by the auxiliary pad 3 can be transferred to the base napkin 2.

The liquid-impermeable sheet 29 in the base napkin 2 is made of a material that can prevent excrement absorbed by the pad-side absorbent portion 30, the central portion 20, and the side portions 21A and 21B from leaking outside. In addition, by using a moisture-permeable material, it is possible to reduce stuffiness at the time of wearing, and to reduce discomfort at the time of wearing. Such materials include, for example, a liquid-impermeable film mainly composed of polyethylene (PE), polypropylene (PP), etc., a breathable film, a composite in which a liquid-impermeable film is laminated on one side of a nonwoven fabric such as spunbond. For example, the seat portion. Preferably, a hydrophobic nonwoven fabric, a water-impermeable plastic film, a laminate sheet portion of a nonwoven fabric and a water-impermeable plastic film, or the like can be used. Further, an SMS nonwoven fabric sandwiched between a melt-blown nonwoven fabric with high water resistance or a strong spunbond nonwoven fabric may be used. For example, the liquid-impermeable sheet 29 in the first embodiment is exemplified by a PE film having a basis weight of 25 g / m ² .

  Although it is preferable that the length of the auxiliary pad 3 in the width direction of the pad-side absorbent portion 30 is generally uniform as a whole, it may not be uniform. Specifically, for example, the width can be gradually reduced toward the rear edge 230 side of the base napkin 2 along the longitudinal direction of the auxiliary pad 3. For the purpose of preventing liquid leakage, the pad-side absorbent portion 30 is formed such that the width in the width direction gradually increases toward the rear edge 230 of the base napkin 2. be able to.

  Further, the width dimension of the base napkin 2 excluding the wings 23A and 23B is, for example, 70 mm to 120 mm, preferably 80 mm to 110 mm. And in 1st Embodiment, 105 mm can be illustrated, for example. Further, the width dimension of the central portion 20 is, for example, 15 mm to 60 mm, preferably 25 mm to 50 mm. And in 1st Embodiment, it is illustrated that it is 40 mm, for example. Further, the width dimension of the side portions 21A and 21B is, for example, 5 mm to 30 mm, preferably 7.5 mm to 25 mm. And in 1st Embodiment, it is illustrated that it is 20 mm, for example.

The absorbent material in the absorbent body 200 when the absorbent body is disposed in the pad-side absorbent body 35 of the pad-side absorbent section 30, the side absorbent bodies 213A and 213B of the base napkin 2, and the central portion 20 is menstrual blood or the like. It preferably has a function of absorbing and holding a liquid, is bulky, hardly loses its shape, and has little chemical stimulation. For example, the absorber material which consists of a fluffy pulp or an airlaid nonwoven fabric and a superabsorbent polymer can be illustrated. Examples of the fluffy pulp include artificial cellulose fibers such as chemical pulp, cellulose fiber, rayon, and acetate. As an airlaid nonwoven fabric, for example, a nonwoven fabric in which pulp and synthetic fibers are thermally fused or fixed with a binder can be exemplified. Examples of the superabsorbent polymer include starch-based, acrylic acid-based, and amino acid-based particulate or fibrous polymers. Moreover, as a nonwoven fabric, nonwoven fabrics, such as a spun lace, a spun bond, a thermal bond, a melt blown, a needle punch, an air through, are used, for example. Examples of the material fibers constituting the nonwoven fabric include olefin-based fibers such as polyethylene or polypropylene, polyester-based fibers, polyamide-based synthetic fibers, regenerated fibers such as rayon and cupra, and natural fibers such as cotton. As the cushion, for example, liquid permeable paper or cellulose sheet portion is used. As an example of the absorbent body in which the cushion and the absorbent material are combined, the pulp has a basis weight of 200 g / m ² , the polymer has a basis weight of 4 g / m ² (the polymer is dispersed throughout), and the pulp and the polymer are uniform throughout. And a mixture in which the mixture is wrapped with a tissue having a basis weight of 15 g / m ² .

  It is preferable that 3% or more of the absorptive polymer used as the above-described absorber material is contained in the entire absorber material used as various absorbers. More preferably, it is contained from 10% to 50%. Furthermore, an absorptive polymer can be unevenly distributed in various absorbers. Specifically, for example, the pad side absorption unit 30 can include a relatively small amount in the region corresponding to the body excretion opening portion contact assumption portion Z and can include a relatively large amount in the region on the rear edge 230 side. .

  Adhesives used for the pad side latching portions 37f and 37r are not only adhesives such as acrylic adhesives and rubber adhesives, but also cellulose-based, polyvinyl alcohol-based, and gelatin that adhere to the skin and exert adhesive force. Polyamino acid gels such as polyglutamic acid and polylysine can also be used.

  The topsheet 33 and the pad-side absorber 35 are joined so that each is bonded with a hot melt adhesive. Further, the top sheet 33 and the back sheet 34 are bonded so as to be bonded together by a bonding portion formed by hot melt adhesive, thermocompression bonding, or the like. As a whole, the surfaces of the sheets are bonded to each other with a hot melt adhesive, and the end portions of the sheets are bonded by bonding portions formed by thermocompression bonding. In addition, joining is not restricted to the said hot melt adhesion, For example, you may use heat embossing, an ultrasonic wave, etc. individually or in combination.

Examples of the coating pattern when bonded by hot melt bonding include spiral coating, control seam coating, coater coating, curtain coater coating, and summit gun coating. The basis weight of the adhesive in hot melt bonding is preferably 1 g / m ² to 30 g / m ² , and more preferably 3 g / m ² to 10 g / m ² . In the case of a pattern in which the adhesive is coated in a linear shape, the wire diameter is preferably 30 μm to 300 μm.

  For example, heat embossing, ultrasonic waves, hot-melt adhesive, etc. are used alone as the bonding material in bonding the base material sheets 11 and 13 and the elastic material 12 or bonding the base material sheet 11 and the base material sheet 13. Or a combination of these can be used. For example, hot-melt adhesive is applied to the base sheet 11 by a coating method such as spiral coating, coater coating, curtain coater coating, summit gun coating, etc., and an elastic material 12 is stacked thereon, The base material sheet 13 is superimposed and joined on it. In order to make it difficult for the elastic material 12 to come off from the base material sheets 11 and 13, the elastic material 12 may be applied in advance by a coating method such as slit coating or control seam coating.

  Examples of the hot-melt adhesive include pressure-sensitive adhesives, heat-sensitive adhesives, and water-soluble polymers mainly composed of rubbers such as SEBS, SBS, and SIS, and olefins such as linear low-density polyethylene. Examples thereof include water-sensitive adhesives such as polyvinyl alcohol, carboxymethyl cellulose, gelatin and the like, or polyvinyl acetate and sodium polyacrylate made of a water-swellable polymer. Preferably, for example, even if the adhesive oozes out, it is preferable to use a heat-sensitive adhesive that does not have tackiness at that time. Specific examples include SEBS from 5% to 25%, alicyclic saturated hydrocarbons from 40% to 60%, aromatic modified terpenes from 1% to 10%, and additives from 15% to 35%. What was melt-mixed can be illustrated.

  For example, a hot-melt adhesive can be used as a locking material in the pad side locking portions 37f and 37r that lock the auxiliary pad 3 and the undergarment 55 or the base napkin 2. The hot melt adhesive preferably has tackiness at room temperature, and examples thereof include a pressure sensitive adhesive. The main components of this adhesive are the same as those exemplified as the above-mentioned bonding material. Specifically, SEBS is from 15% to 25%, plasticizer is from 15% to 35%, and tackifier is from 40%. What melt-mixed within the range of 70% can be illustrated. Moreover, you may add antioxidant, a fluorescent agent, etc. in 0.1 to 1.0% of range. The basis weight is 10 gsm to 200 gsm and is applied in a uniform, streaky or dot pattern by coater coating, bead coating, or the like. An acrylic adhesive may also be used. Furthermore, it is good also as what latches using the several hook part which stands on the surface of each tape-shaped part.

  Specifically, the tape-shaped part is formed by extruding a thermoplastic synthetic resin such as polypropylene, and the rib structure part formed integrally with the tape part is subjected to processing such as cutting and excision, on the surface of the tape-shaped part. A hook portion is formed. Alternatively, the hook portion may be formed by cutting a monofilament loop made of a thermoplastic synthetic resin provided on the surface of the tape-shaped portion from the side. Furthermore, in order to reduce the risk of damaging the skin, the end surface of the hook portion may be rounded. Specifically, the roundness of the top of the hook can be exemplified by the shape of the mold. Note that the cross-sectional shape of the hook portion is not particularly limited, and examples thereof include a tapered shape and a T-shape.

  On the other hand, by providing the pad side latching portion 37 on the skin contact surface side of the belt-like member 10, the pad side latching portion 37 that is not fixed to the underwear 55 but fixed to the wearer's body side is water-soluble. Examples thereof include a polymer, a crosslinking agent, a plasticizer, and a gel pressure-sensitive adhesive composed of moisture. Specifically, examples of the water-soluble polymer include gelatin, sodium polyacrylate, polyvinyl alcohol, carboxymethyl cellulose and the like. Examples of the crosslinking agent include water-soluble metal salts such as calcium chloride and magnesium sulfate, and examples of the plasticizer include glycerin, wax, and paraffin.

  For pressure-sensitive adhesives and pad-side locking portions 37, a sheet of silicon paper coated on a thin paper, which is a release paper that generally provides a tacky portion, or a film coated with a silicon resin It is preferable to coat with. This is because the adhesive part can be prevented from being soiled or peeled off during storage.
