Description

Absorbent article worn by body

  The present invention includes sanitary napkins and urine absorbing incontinence pads (including not only large nursing care items but also small light incontinence items), absorbent pads attached to diaper covers, etc. The present invention relates to an absorbent article of a type to be attached to a body wear product.

  For example, a sanitary napkin is generally attached by using the napkin on the inner surface of the shorts crotch part and sticking it to the inner surface of the shorts crotch part, with the shorts lowered to some extent in use. At this time, if the mounting position with respect to the shorts is inappropriate, the napkin will be displaced or twisted, causing leakage or worsening of the mounting feeling. For this reason, conventionally, the user determines the mounting position depending on experience and intuition. The problem and the method for determining the mounting position are the same for the incontinence pad and the absorbent pad for the pad-type diaper.

However, when wearing these absorbent articles, the user positions the absorbent article on the body-wearable product while observing the absorbent article from the opposite side with respect to the wearing surface on the body-wearable product side. Therefore, the positional relationship between the two could not be accurately grasped, and proper wearing was difficult.

  As described above, according to the present invention, there are advantages such as an absorbent article that can be easily and appropriately attached to a body-wearable product.

  Since the present invention can be broadly divided into those in which a sign is provided on an absorbent article and those configured so that the side edges of the body-wearable product can be visually recognized, these will be divided below and attached to each embodiment. It will be explained in detail with reference to.

<First form according to side edge marking>
FIGS. 1 and 2 show a configuration in which a side edge marking is provided to a sanitary napkin 1 with a folded flap. The sanitary napkin 1 includes a back sheet 2 and a liquid-permeable top sheet 3 that allows menstrual blood, urine and the like to permeate quickly. Between these two sheets 2 and 3, it consists of the absorption core 4 which consists of cotton-like pulp, synthetic pulp, etc., and the crepe paper 5 which surrounds the absorption core 4 for the shape maintenance of this absorption core 4, and a diffusivity improvement. An absorber is interposed. This absorber constitutes an absorption element material together with an absorption promotion sheet described later.

Side sheets 6 and 6 formed along the longitudinal direction are provided on both sides of the surface. Incidentally, crepe paper 5 is not shown in order to prevent ambiguous drawings in FIG. 1, those that reach both longitudinal ends of the absorbent core 4.

  In the periphery of the absorbent core 4, the outer edges of the back sheet 2 and the liquid-permeable top sheet 3 are joined at the upper and lower end edges by an adhesive such as hot melt or an adhesive means such as heat seal. At the edge, the back sheet 2 and the side sheet 6 extending to the side of the absorbent core 4 are joined by an adhesive such as hot melt or an adhesive means such as heat sealing.

  As the back sheet 2, a sheet material that does not transmit at least body fluid (determined according to the type of the absorbent article) such as an olefin resin sheet such as polyethylene or polypropylene is preferably used. A laminated nonwoven fabric obtained by laminating a nonwoven fabric, etc., or a nonwoven fabric sheet that is substantially impervious to liquids by interposing a waterproof film (in this case, the back sheet is composed of the waterproof film and the nonwoven fabric). Can be used. In recent years, those having moisture permeability tend to be used from the viewpoint of preventing stuffiness. The water- and moisture-permeable sheet material is a microporous sheet obtained by kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. There is.

  As the liquid-permeable top sheet 3, a porous or non-porous nonwoven fabric or a porous plastic sheet is preferably used. Examples of the material fibers constituting the nonwoven fabric include synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester and polyamide, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as a lace method, a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in terms of flexibility and drapeability, and the thermal bond method is excellent in terms of being bulky and soft.

  The crepe paper 5 surrounding the absorbent core 4 is interposed between the liquid-permeable top sheet 3 and the absorbent core 4, and rapidly diffuses menstrual blood and urine (hereinafter collectively referred to as body fluid). And has a function of preventing the return of body fluid. With this function, the surface in contact with the skin has excellent dry touch properties.

  The absorbent core 4 interposed between the back sheet 2 and the liquid-permeable top sheet 3 is composed of, for example, fluffy pulp and a water-absorbing polymer. The water-absorbing polymer is mixed as, for example, granular powder in the pulp constituting the absorbent core. Examples of the pulp include chemical fibers obtained from wood, cellulose fibers such as dissolving pulp, and artificial cellulose fibers such as rayon and acetate. Softwood pulp having a longer fiber length than hardwood pulp functions and It is preferably used in terms of price.

  Further, in the unfolded state of the sanitary napkin 1, side sheets 6 and 6 are provided on both sides of the surface along the longitudinal direction and over substantially the entire length of the absorbent article. And the front-rear direction substantially center part of these side seats 6 and 6 is extended to the side, and the corresponding part of the back sheet 2 is also extended to the side and extended to these sides. The flap portion W is formed by joining the side sheet 6 portion (which constitutes the flap top sheet of the present invention) and the back sheet 2 portion (which constitutes the flap back sheet of the present invention) with a hot-melt adhesive or the like. , W are formed. The flap portions W, W are folded to the back side when the product is provided, and when worn, the flap portions W, W are once peeled off and opened, and then folded again so as to contact the outer surface of the crotch portion of the body-worn product (see FIG. 2).

As the side sheet 6, a water-repellent treated nonwoven fabric or a hydrophilic treated nonwoven fabric can be used depending on the function regarded as important. For example, if importance is placed on functions such as preventing permeation of menstrual blood or vaginal discharge, or enhancing the touch feeling, water repellent treatment coated with silicon, paraffin, alkylchromic chloride water repellent, etc. A nonwoven fabric can be used. Further, if importance is attached to the absorbability of menstrual blood and the like in the flap portions W, W, a method of polymerizing a compound having a hydrophilic group, such as an oxidation product of polyethylene glycol, in the synthetic fiber production process, Treating with metal salt such as stannic, partially dissolving the surface to make it porous and making the synthetic fiber swell or porous by applying a metal hydroxide, etc., applying capillary action to impart hydrophilicity A hydrophilically treated nonwoven fabric can be used. It is desirable to use a hydrophilic nonwoven fabric as the side sheet 6. As a basic material of such a side sheet 6, natural fibers, synthetic fibers, regenerated fibers, or the like, which are formed by an appropriate processing method, can be used. Preferably, the basis weight is suppressed and air permeability is reduced. Ru using the have to have non-woven fabric.

The inner portions of the side sheets 6 and 6 extend inward from the side edges of the absorbent core 4 (this inwardly extending portion constitutes the barrier portion of the present invention), and the liquid-permeable top in a double sheet state. is bonded by a hot melt adhesive on the sheet 3 is folded back from the adhesive side edges outward, elastically stretchable members 6A, such as rubber thread, 6A are bonded by hot melt adhesive in a stretched state to the folded portion . The longitudinal front and rear end portions of the folded portion of the side sheet 6 are bonded to each other in a superposed state with a hot melt adhesive, but the intermediate portion is not bonded. Therefore, in the state of use, as shown on the left side of FIG. 2, the folded portion is raised by the contraction force of the elastic elastic members 6A and 6A, and functions as a barrier B for preventing menstrual blood leakage. .

  And in this 1st form, the side edge marking 10 which concerns on this invention is provided in the flap parts W and W of this sanitary napkin 1, respectively. The side edge marking 10 of the present invention serves as a standard for aligning the side edges 21 of the crotch portion 20 of the body-wearable product, and is opposite to the mounting surface on the body-wearable product side (in this case, the back surface). As long as it is visible from the front side), the formation method is not particularly limited, but in the present invention, in consideration of manufacturability, a method using an adhesive / adhesive, a method using printing And three types of methods using embossing / debossing are proposed. In the first embodiment, a method using a pressure-sensitive adhesive / adhesive is employed.

  In other words, the sanitary napkin 1 with the folded flap is usually provided with an adhesive 11 for preventing misalignment on the mounting surface of the flap portion W that is in contact with the body-worn item, that is, on the outer surface of the back sheet 2. The pressure-sensitive adhesive 11 is used as the side edge marking 10 of the present invention. Specifically, a colored adhesive is used instead of the normally used transparent adhesive, and instead of or together with this, it is more transparent as a material of the flap portion W (side sheet and back sheet) than before. By using a material having a high thickness and allowing the pressure-sensitive adhesive to be visually recognized from the surface side, it is possible to cause the displacement-preventing pressure-sensitive adhesive 11 to function as the side edge marking 10 of the present invention. Of course, in addition to the pressure-sensitive adhesive 11 intended to prevent misalignment, a pressure-sensitive adhesive intended for side edge marking can be provided. However, the latter pressure-sensitive adhesive also exhibits a function of preventing misalignment.

  Further, as described above, the flap portion W is formed by laminating the side sheet 6 and the back sheet 2 and bonding them with an adhesive. Therefore, the same side edge marking can also be obtained by using a colored material as the adhesive and using a material having higher transparency than the conventional material as the material of the flap portion W (side sheet 6) instead of or together with this. Can be provided in the flap portion W.

  When a highly transparent material is used, a non-porous material with low opacity, a perforated material having a large number of through holes, a bulky nonwoven fabric, or the like can be used as the material. Specifically, it is preferable to use a material having an opacity of 50% or less. It is more preferable that the opacity is 50% or less even in the entire material existing on the viewing side of the side edge marking 10.

  The shape of the side edge marking 10 is not particularly limited as long as it is a standard for matching the side edges of the crotch part of the body-worn product. However, if the shape / arrangement is too irregular, the function as the side edge marking 10 is lowered, which is not preferable. Therefore, the side edge marking 10 has a shape having a portion along the side edge 21 of the crotch portion of the body-worn product, for example, a linear shape along the side edge 21 of the crotch portion of the body-wearable product like the illustrated adhesive 11. In addition to a rectangular shape having an edge, a curved shape (a form to be described later) or a linear shape along the side edge 21 of the crotch portion of the body-worn product, or a dotted line shape using these as a dotted line is suitable.

  Further, the planar position of the side edge marking 10 with respect to the side edge 21 of the crotch portion of the body-wearable product is not particularly limited as long as it is a standard for matching the crotch side edge 21 of the body-wearable product. In the first place, when the body-worn product is underwear, the width of the crotch portion 20 is not constant, and therefore it is impossible to uniquely define the portion where the side edge position 21 is located in the absorbent article 1. On the other hand, if the side edge marking 10 is too far away from the side edge 21 of the body wearable article when being attached to the body wearable article 20, it does not necessarily function as the side edge sign 10 but the effect is as follows. Become thin. Therefore, it is preferable that the reference position of the side edge marking 10 is determined in accordance with the width of the crotch portion 20 of a standard body-wearable product, and the side edge marking is positioned at a position parallel to at least the reference position. In the sanitary napkin 1 of the illustrated form, the position along the base end (base) of the flap W is the reference position, and the adhesive 11 is provided in a rectangular range having an edge parallel to the reference position. Yes.

  In addition, when the body wear product is underwear, considering that the width of the crotch portion 20 is not constant in the first place, a plurality of standard crotch widths are assumed, and a plurality of side edge markings 10 according to each width are assumed. It is also a preferable form to provide.

  In the sanitary napkin 1 thus configured, when the back surface thereof is aligned with the inner surface of the crotch portion 20 of a body-wearable product such as shorts, the proximal end portion of the flap portion W is picked, and the crotch side edge 21 of the body-wearable product is fingertips. By positioning so that the width direction center side edge 11e of the adhesive 11 visually recognized from the surface side is in an appropriate position with respect to the position of the crotch side edge 21 while confirming with In addition, it can be easily and appropriately mounted.

<Second form according to side edge marking>
As shown in FIG. 3, the second embodiment is different from the first embodiment in that the print sheet 12 on which the side edge marking is printed is attached to the flap portion W. The printed sheet 12 is preferably fixed by an adhesive that bonds the sheets 6 and 2 between the side sheet 6 and the back sheet 2 constituting the flap portion W as shown in the figure. It can also be affixed on the surface of the back sheet 2 or a back surface of the back sheet 2.

  When the side sheet 6 exists on the surface side of the position where the printing sheet 12 is provided and the printing sheet 12 becomes visible through the side sheet, a material having higher transparency is used as the material of the side sheet 6. Is preferred. Specifically, it is preferable to use a nonwoven fabric having an opacity of 50% or less as the side sheet 6. Most of the side sheets 6 that are normally used satisfy this condition. In this case, in the structure of the illustrated embodiment, the opacity of the entire material existing on the viewing side of the print sheet 12 is 50% or less.

  Since other points are the same as those in the first embodiment including the modification, the description is omitted.

<Third form of side edge marking>
The third embodiment is the same as the second embodiment in that printing is used, but without providing a dedicated member, the third embodiment directly applies to the sheet constituting the flap portion W as shown in FIGS. It is different in that the side edge marking printing 13 is performed. In the illustrated embodiment, printing 13 is performed directly on the side surface of the side sheet 6 of the back sheet 2, but of course, the present invention is not limited to this, and the back surface of the back sheet 2, the side surface of the back sheet 2 of the side sheet 6, It is also possible to print directly on the surface.

  When the side sheet 6 is present on the surface side of the side edge marking print 13 position and the side edge marking is visible through the side sheet 6, a material having higher transparency is used as the material of the side sheet 6. Is preferred. Specifically, it is preferable to use a nonwoven fabric having an opacity of 50% or less as the side sheet 6. Most of the side sheets 6 that are normally used satisfy this condition. In this case, in the structure of the illustrated embodiment, the opacity of the entire material existing on the viewing side of the side edge marking print 13 is 50% or less.

  Moreover, the side edge marking of this 3rd form is formed in the curve shape which follows the side edge of the crotch part of a body wear article. Providing such curved side markings is preferable because it is easy to form by printing and can be formed with good appearance.

  Since other points are the same as those in the first embodiment including the modification, the description is omitted.

<4th form which concerns on side edge marking>
Although the said 1st-3rd form attaches a side edge mark to the flap part W, this 4th form is a form which attaches the side edge mark 10 to the barrier part B, as shown in FIG. For example, when used for shorts having a narrow crotch width, or in a sanitary napkin designed to have a wide part located between the crotch, the crotch side edge 21 of the body-worn product may overlap with the barrier part B position. In such a case, by providing the side edge marking 10 of the present invention in the barrier portion B, the side edge marking can be easily visually confirmed during use, as in the first embodiment, and can be more easily and appropriately mounted. Will be able to do.

  As a method of providing the side edge marking 10 in the barrier part B, any of the three types described above can be applied. In particular, from the viewpoint that no additional members are required and there is little influence on the function of the barrier portion, a method of directly printing the side edge marking 10 on the front surface, the overlapping surface or the back surface of the side sheet 6 constituting the barrier portion is preferable. It is. From the same point of view, it is also preferable to change the adhesive used for bonding between the side sheets 6 constituting the barrier portion B to a colored color to form the side edge marking 10. However, of course, a sheet provided with side edge marking printing in advance can be attached to the front or back surface of the side sheet 6 or interposed between the side sheets 6.

  In the case where the side sheet 6 is present on the surface side from the position where the side edge marking 10 is formed and the side edge marking 10 is visible through the side sheet 6, a material having higher transparency as the material of the side sheet 6. Is preferably used. Most of the side sheets 6 that are normally used satisfy this condition. Specifically, it is preferable to use a nonwoven fabric having an opacity of 50% or less as the side sheet 6. In this case, in the structure of the illustrated embodiment, the opacity of the entire material existing on the viewing side of the side edge marking 10 is 50% or less.

  Other points are the same as those of the first embodiment including the modification.

<5th form which concerns on side edge marking>
The fifth form is used for shorts that are narrower than the fourth form, or an absorbent article designed to have a wider part located between the crotch, for example, for nursing care as shown in FIGS. In the large urine absorption pad 100 such as the above, the crotch side edge of the body-worn product overlaps with the absorbent body 4. Since the basic structure is not different from the sanitary napkin 1 described above, the same reference numerals and terms as those in the first embodiment are used, and the description thereof is omitted.

  In such a case, it is preferable to provide the side edge marking 10 at a position overlapping the absorber 4. However, the opacity is lowered by sacrificing the absorption performance of the absorber 4 using a normal material, or the absorber 4 is formed using a material having as low an opacity as possible without sacrificing the absorption performance of the absorber 4. Unless it is provided, even if the side edge marking 10 is provided on the back surface side of the absorbent body 4, that is, the back surface of the absorbent body 4, between the absorbent body 4 and the back sheet 2, it is visible from the front surface side. This makes it impossible or difficult, and does not have the original function of side edge marking in the present invention.

In such a case, the fifth embodiment shown in FIGS. 7 and 8 is configured such that the side edge marking 10 is visible from the surface side. Specifically, in the illustrated embodiment, the side edge marking 10 is provided on the liquid-permeable top sheet 3. In addition, if it is the surface side of the absorber 4, the surface or back surface of the liquid-permeable top sheet 3, or between the liquid-permeable top sheet 3 and the absorber 4, and the liquid-permeable top sheet in the absorber 4. It can also be provided on three side surfaces. In these cases, when the top sheet 3 is present on the surface side from the position where the side edge marking 10 is formed, it is preferable to use a material having higher transparency as the material of the top sheet 3. Most commonly used topsheets 3 satisfy this condition. Specifically, it is preferable to use a non-woven fabric having an opacity of 50% or less as the top sheet 3. Further, when there is a sheet other than the top sheet 3 on the viewing side of the side edge marking 10, it is more preferable that the opacity of the whole material is 50% or less.

  On the other hand, as the method for forming the side edge marking 10, any of the three types described above can be applied. In particular, from the standpoint that no additional members are required and there is little influence on the absorption function, and in some cases the absorption function can be improved, the side edge marking 10 is provided by embossing or debossing (hereinafter referred to as embossing or the like). preferable. In this case, by providing embossing or the like to the liquid-permeable top sheet 3 as shown in the figure by embossing or the like, the embossing or the like provides unevenness in the depth range extending from the liquid-permeable top sheet 3 to the absorber 4. It can also be granted. These embossings affect the absorption function depending on the forming member, the planar arrangement, and the depth of the irregularities. For example, when the recesses 14 are formed in a row, the body fluid can easily flow along the recesses 14, thereby improving the diffusibility of the body fluid and damming the body fluid. Therefore, when the side edge marking 10 by embossing or the like is provided, it is preferable to take an arrangement in consideration of the absorption control function.

  Of course, a method of directly printing the side edge marking 10 on the front or back surface of the liquid-permeable top sheet 3 or on the side surface of the liquid-permeable top sheet 3 in the absorber 4 can also be adopted. Moreover, the printing sheet which printed the edge mark 10 previously can be affixed on the surface or back surface of the liquid-permeable top sheet 3, or can be interposed between the liquid-permeable top sheet 3 and the absorber 4. In order to improve the diffusibility of body fluid, etc., a second sheet may be provided at this site. In this case, this second sheet can be used as a printing sheet. Furthermore, the side edge marking 10 can also be formed on the back surface of the liquid-permeable top sheet 3 using a colored adhesive. In this case, since the end of the liquid-permeable top sheet 3 is fixed by an adhesive, when the side edge marking 10 is provided at the part, it may have a function for fixing and a side edge marking. it can.

  Other points are the same as those of the first embodiment including the modification.

<Form in which the side edge of the body-wearable product is visible>
On the other hand, each of the above forms is intended to facilitate and optimize wearing by providing a side edge marking portion on the absorbent article. The absorbent article which comprised so that the side edge of the crotch part itself could be visually recognized from the opposite side with respect to the mounting surface used as the body wear goods side is also proposed.

  As its specific means, it is possible to adopt a notch corresponding to the side edge of the crotch part of the body-worn product in the absorbent article, but if the material of the corresponding part is composed of a member with more transparency, the material change This is preferable because a simpler configuration is possible, such as being able to cope with the situation alone.

  In order to increase the transparency of the corresponding part, a thin needle is used for the material of the corresponding part (for example, a flap part when a side mark is provided on the flap part, and a barrier part when a side mark is provided on the barrier part). Uses a large number of minute through-holes or uses a punched sheet provided with a large number of punch holes to some extent, uses a bulky nonwoven fabric, and the material itself has low opacity (for example, transparent or translucent) This can be achieved by using a non-porous sheet.

Thus, in the constructed absorbent article, when the back surface of the absorbent article is aligned with the inner surface of the crotch portion of the body-worn product such as shorts, the crotch side edge of the body-worn product is visually recognized while being positioned at the position of the crotch side edge. On the other hand, by positioning the absorbent article so as to be in an appropriate position, the absorbent article can be easily and appropriately mounted without depending on intuition. In addition, since the external appearance of this form only showed the crotch part side edge 21 itself of a body-wearable article in the side edge marking part of FIG. 4, illustration was abbreviate | omitted.

<Others>
(A) The side edge marking form and the side edge visualization form in the present invention can be applied in combination.
