BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described based on its preferred embodiments with reference to the drawings. In addition, in the following description of the drawings, the same or similar reference numerals are given to the same or similar parts. The drawings are basically schematic, and the ratio of each dimension may differ from the actual one.

1 to 4 show an absorbent pad 1, which is one embodiment of the absorbent pad of the present invention. FIG. 5 shows, as an example of use of the absorbent pad of the present invention, a disposable diaper 10 (hereinafter also referred to as "diaper 10") including an absorbent pad 1 and a holder 11 for holding the absorbent pad 1 in a state in which it is worn by a wearer. Say.) Shown. Diaper 10 is an embodiment of the absorbent article of the present invention, that is, an absorbent article comprising the absorbent pad of the present invention and a holder to which the absorbent pad can be attached. As shown in FIG. 5, the diaper 10 is constructed by connecting the absorbent pad 1 and the holder 11 via the pad-side fastening structure 8 and the holder-side fastening structure 14, and the waist opening of the holder 11. WH and a pair of leg openings LH, LH defined by the lower end in the height direction HD of the holder 11 and both side edges along the longitudinal direction (longitudinal direction X described later) of the absorbent pad 1. . Note that the holder 11 is not a component of the absorbent pad 1 .

In the diaper 10, which is a separate type absorbent article, the absorbent pad 1 and the holder 11 can be freely connected and separated via the fixing structures 8, 14, so compared to conventional non-separate type absorbent articles, The load on the environment is reduced. That is, a conventional non-separate type absorbent article is used in which the portion corresponding to the waist of the wearer (portion corresponding to the holder) and the portion corresponding to the crotch portion of the wearer (portion corresponding to the absorbent pad) are inseparably integrated. When discarding later, even if the part corresponding to the holder is not soiled, it has to be discarded together with the part corresponding to the absorbent pad that is soiled with excrement. Since only the pad 1 needs to be replaced with a new one, the amount of garbage disposal and the amount of carbon dioxide emissions are reduced compared to non-separate type absorbent articles, and it is possible to contribute to the reduction of the load on the environment.
In addition, since the absorbent pad 1 is detachably fixed to the holder 11 while the diaper 10 is being worn, the work of replacing the absorbent pad 1 with a new one is simple, and the diaper 10 is similar to the conventional non-separate type. The burden of replacement work is greatly reduced compared to other absorbent articles.

The absorbent pad 1 is used by being removably fixed to a holder 11 that is annularly worn around the wearer's waist. Here, the holder 11 will be briefly described with reference to FIG. 5. The holder 11 is worn in a circular shape around the wearer's waist and holds the absorbent pad 1 in a state of being worn by the wearer. It has a height direction HD along the height direction of the wearer and a circumferential direction CD along the waist direction. The holder 11 has an abdominal portion 11F arranged on the wearer's ventral side (front side) and a dorsal portion 11R arranged on the wearer's dorsal side (rear side), and constitutes the main body of the holder 11. A holder body portion 12 is provided. The holder main body 12 is mainly composed of a sheet-like member such as a non-woven fabric, and is typically composed of an outer layer sheet forming a non-skin facing surface (outer surface) of the holder main body 12 and a skin of the holder main body 12. It is configured including a laminated structure with an inner layer sheet forming an opposing surface (inner surface). The holder 11 has an annular shape by joining both ends in the longitudinal direction of the holder main body 12 of the ventral part 11F and the dorsal part 11R by a known joining means such as fusion bonding or adhesive. It has a pair of joints S, S between the portion 11F and the dorsal portion 11R, and a waist opening WH. The joint portion S corresponds to a side seal portion in a general non-separate pants-type disposable diaper. A plurality of elastic members 13 arranged to be stretchable in a direction perpendicular to the height direction HD are intermittently arranged in the height direction HD, Thereby, the holder 11 has elasticity in the circumferential direction CD. A holder-side fastening structure 14 is arranged on the non-skin-facing surface (outer surface) of the holder main body 12, and the pad-side fastening structure 8 of the absorbent pad 1 is fastened to the holder-side fastening structure 14. , the absorbent pad 1 can be attached to the holder 11 in a detachable manner.
Since the holder 11 does not include an absorber that absorbs and retains moisture, if a washable component is used as the component of the holder main body 12, it can be washed and used repeatedly. The washability of the holder 11 leads to a reduction in the amount of garbage disposal and carbon dioxide emissions, and can contribute to a reduction in the burden on the environment.
Note that the holder 11 is merely one embodiment of a holder to which the absorbent pad of the present invention can be applied, and the holder to which the absorbent pad of the present invention can be applied is attached to the pad-side fastening structure of the absorbent pad. It is not limited to the holder 11 as long as it has a holder-side fixing structure that can be worn. For example, the holder to which the absorbent pad of the present invention can be applied may have a ring shape when attached to the body, or may have a ring shape in advance like the holder 11, or may have a ring shape before being attached to the body. It may have a belt-like shape elongated in the direction, and may be formed into a ring shape by engaging one end portion and the other end portion in the longitudinal direction when it is mounted.

As used herein, the term “skin-facing surface” refers to a wearing article such as an absorbent article, a holder, an absorbent pad, or a constituent member thereof (e.g., an absorbent body of an absorbent pad), which is worn by the wearer when the wearing article is worn. The "non-skin facing surface" refers to the surface of the wearing article or its constituent members that faces away from the skin when the wearing article is worn.

The absorbent pad 1 will be described in detail below.
The absorbent pad 1 comprises a top sheet 3 positioned closer to the wearer's skin when worn, a back sheet 4 positioned farther from the wearer's skin, and an absorbent body positioned between the two sheets 3 and 4. 5 and has a longitudinal direction X and a transverse direction Y perpendicular thereto. The longitudinal direction X of the absorbent pad 1 corresponds to the front-rear direction passing through the crotch of the wearer and the height direction HD of the holder 11 , and the lateral direction Y of the absorbent pad 1 corresponds to the circumferential direction CD of the holder 11 . corresponds to

The first leak-preventing cuff 6 is positioned at the end region in the lateral direction Y to prevent excrement from leaking outward in the lateral direction Y, and can be called a "lateral leak-preventing cuff". can. The second leak-preventing cuff 7 is positioned at the end region in the longitudinal direction X to prevent the excrement from leaking outward in the longitudinal direction X, and can be called a "vertical leak-preventing cuff". can. The term "longitudinal end region" as used herein may be an end region in the longitudinal direction X when the absorbent pad 1 is divided into three in the longitudinal direction X (regions other than the center in the longitudinal direction X).

The absorbent main body 2 constitutes the main body of the absorbent pad 1 and has a function of absorbing and retaining excrement such as urine. In this embodiment, the absorbent main body 2 has a shape elongated in the longitudinal direction X, and extends in the longitudinal direction X from the ventral part F to the dorsal part R with its longitudinal direction aligned with the longitudinal direction X. there is The topsheet 3 forms the skin-facing surface of the absorbent body 2 and can come into contact with the wearer's skin when worn. The backsheet 4 forms the non-skin facing surface of the absorbent body 2 . The top sheet 3 is in contact with the skin facing surface of the absorbent body 5 and covers the entire area thereof, and the back sheet 4 is in contact with the non-skin facing surface of the absorbent body 5 and covers the entire area. The absorbent body 5 includes an absorbent core 51 capable of absorbing and retaining bodily fluids, and a core wrap sheet 52 covering the outer surface of the absorbent core 51 including the skin-facing surface and the non-skin-facing surface. In the present invention, the absorbent body 5 only needs to include at least the absorbent core 51, and the core wrap sheet 52 may be omitted. The plurality of members 3, 4, 5 constituting the absorbent main body 2 are integrated with each other by known joining means such as an adhesive.

As the constituent members of the absorbent main body 2, those commonly used in this type of absorbent article can be used without particular limitation.
As the surface sheet 3, a liquid-permeable sheet can be used, and examples thereof include nonwoven fabrics produced by various methods, perforated nonwoven fabrics that have through holes, and uneven nonwoven fabrics in which at least one surface of a nonwoven fabric is given an uneven shape. , perforated films, which are resin films having through holes, and the like. Further, the surface sheet 3 may have a single-layer structure, or may have a laminated structure in which one or two or more layers are laminated.
As the backsheet 4, a liquid-impermeable or liquid-impermeable sheet or a water-repellent sheet can be used.
The absorbent core 51 is typically mainly composed of a water-absorbent material, and contains one or more selected from fiber materials such as wood pulp and water-absorbent polymers as the water-absorbent material. The water-absorbing material may be uniformly distributed throughout the absorbent core 51, or may be unevenly distributed in a predetermined direction such as the longitudinal direction X, the lateral direction Y, or the thickness direction. The absorbent core 51 may be of a laminated type mainly composed of fiber material, or may be of a sheet type including a fiber sheet and water-absorbent polymer particles fixed thereto. The fiber stacking type absorbent core can be manufactured, for example, using a known fiber stacking device equipped with a fiber stacking drum. The sheet-type absorbent core has, for example, a configuration in which water-absorbent polymer particles are interposed between two fiber sheets facing each other. The core wrap sheet 52 has liquid permeability and is typically made of paper, nonwoven fabric, or the like.
The absorbent body 5 may have recesses having openings in at least one of the skin-facing surface and the non-skin-facing surface. The recess may be, for example, a leak-proof groove having an opening on the skin-facing surface of the absorbent body 5 . The absorbent body 5 may have partially different densities, and the relatively high-density portion in that case may be a portion formed by pressing such as embossing.

The first leak-proof sheet 60 forms part of the skin-facing surface of the absorbent pad 1 . The first leak-proof sheet 60 is folded back in the horizontal direction Y, and the first elastic member 61 is arranged between the first leak-proof sheets 60, 60 facing each other by folding. The first leak-proof cuff 6 (first leak-proof sheet 60) is arranged continuously along the side portion along the longitudinal direction X of the absorbent main body 2 over substantially the entire length of the absorbent main body 2 in the longitudinal direction X. there is
The first leak-proof cuff 6 has, at least at the crotch part M, a standing part 62 that stands up against the wearer's skin when the absorbent pad 1 (diaper 10) is worn. The standing portion 62 stands up toward the wearer's skin with the fixed portion 63 as a standing point. The standing portion 62 is a portion of the first leak-proof sheet 60 that is not fixed to other members. The fixed portion 63 is a portion where the first leak-proof sheet 60 is fixed to another member by a known joining means such as adhesive or fusion. be.
At both end regions of the first leak-proof cuff 6 in the longitudinal direction X, stand-up inhibiting portions 64 that are portions where the first leak-proof sheet 60 is inhibited from standing up are formed. The erection inhibiting portion 64 is formed in the ventral portion F and the dorsal portion R, and the portion along the longitudinal direction X between the erection inhibiting portions 64, 64 of the first leak-proof cuff 6 is the erecting portion 62. be. The erection-inhibiting portion 64 has a portion that is located at the same position in the lateral direction Y as the erecting portion 62 of the first leak-proof sheet 60. It is a portion joined to another portion of the by a known joining means such as an adhesive or fusion. A pair of erection inhibiting portions 64, 64 are formed in both end regions of the first leak-preventing cuff 6 in the longitudinal direction X, so that when the absorbent pad 1 (diaper 10) is worn, the first leak-preventing cuff 6 When the first elastic member 61 contracts, the standing portion 62, which is the portion sandwiched between the standing-up inhibiting portions 64, 64, stands up toward the wearer's skin with the fixing portion 63 as the standing starting point. As a result, so-called lateral leakage, in which excrement such as urine excreted by the wearer leaks outward in the lateral direction Y from the absorbent pad 1, is suppressed.
As the first leak-proof sheet 60, any material that is used as a material for leak-proof cuffs in this type of absorbent article can be used without particular limitation. and a nonwoven fabric can be used.

The second leak-proof sheet 70 forms at least part of the skin-facing surface of the abdominal portion F or the back portion R of the absorbent pad 1 . As the second leak-proof sheet 70, the same material as the first leak-proof sheet 60 can be used.
In this embodiment, the configuration of the second leak-proof cuff 7 is the same for the ventral portion F and the dorsal portion R, and unless otherwise specified The description of the leak-preventing cuff 7 also applies to the other second leak-preventing cuff 7 as appropriate.

In this embodiment, the second leak-proof sheet 70 has a quadrangular shape in plan view, and covers substantially the entire skin-facing surface of the absorbent main body 2 at the end regions in the longitudinal direction X. As shown in FIG. As shown in FIG. 4, of the longitudinal direction X ends of the second leak-proof sheet 70, the longitudinally outer end 70X1 positioned outward in the longitudinal direction X is the absorbent sheet 70 on which the second leak-proof sheet 70 is arranged. Both ends 70Y, 70Y in the lateral direction Y of the second leak-proof sheet 70 coincide with the longitudinal ends of the absorbent body 2 (the longitudinal ends on the ventral side F side or the dorsal side R side). It is near both ends in the horizontal direction Y (both edges along the vertical direction X). That is, in this embodiment, the longitudinal outer end 70X1 of the second leak-proof sheet 70 coincides with the longitudinal outer end 1X of the absorbent pad 1, and the lateral end 70Y of the second leak-proof sheet 70 It is in the vicinity of the laterally outer edge (side edge along the longitudinal direction X) 1Y of the physical pad 1. As shown in FIG. Of the longitudinal direction X ends of the second leak-proof sheet 70, the longitudinal inner end 70X2 located inward in the longitudinal direction X extends parallel to the lateral direction Y. As shown in FIG.

As shown in FIG. 4, the second leak-proof sheet 70 has a fixed portion 72 (a hatched area in FIG. 4) fixed to another member and a non-fixed portion 75 not fixed to another member. and The "other member" to which the second leak-proof sheet 70 is fixed is a member arranged to face the second leak-proof sheet 70, such as the top sheet 3 and the first leak-proof sheet 60, for example. The second leakproof sheet 70 and other members are joined by fixing means 79 (see FIG. 3(a)). The arrangement area of the fixing means 79 is the same as that of the fixing portion 72 (the hatched area in FIG. 4). The fixing means 79 is not particularly limited, and known fixing means such as adhesive and fusion bonding can be used.
The fixing part 72 includes a continuous fixing part 73 in which the fixing part between the second leakproof sheet 70 and other members extends continuously over the entire length of the absorbent main body 2 in the horizontal direction Y, and A discontinuous fixing portion 74 located inside the direction X and adjacent to the continuous fixing portion 73, and intermittently in the lateral direction Y, where the fixing portion between the second leakproof sheet 70 and other members is present, A non-fixed portion 75 is positioned between a pair of discontinuous fixed portions 74, 74 adjacent in the lateral direction Y. As shown in FIG.

As shown in FIG. 4, a second elastic member extending in the lateral direction Y is provided at the longitudinal direction X end (the longitudinal direction X inner end) of the second leak-proof sheet 70 on the longitudinal direction inner end 70X2 side. 71 is arranged so as to be able to expand and contract in the horizontal direction Y. In the present embodiment, the second elastic member 71 is arranged so as to straddle the pair of discontinuous fixed portions 74, 74 and the non-fixed portion 75 therebetween in the horizontal direction Y. The arrangement pattern of the members 71 is not particularly limited. For example, in the embodiment shown in FIG. may not extend to the pair of discontinuous fixing portions 74, 74 on both sides of the . Alternatively, the discontinuous fixing portion 74 may not be arranged in a region overlapping the second elastic member 71 and its imaginary extension line in plan view (a region located at the same position as the second elastic member 71 in the longitudinal direction X). .
The number of second elastic members 71 to be arranged is not particularly limited, and may be one or more. In this embodiment, the inner end portion of the second leak-proof sheet 70 in the longitudinal direction X is folded back toward the skin-facing surface side or the non-skin-facing surface side of the second leak-proof sheet 70, and the folded back forms the Two second elastic members 71 are arranged between the second leak-proof sheets 70, 70 facing each other.
When the absorbent pad 1 is worn or in its natural state, contraction of the second elastic member 71 causes the non-fixed portion 75 of the second leak-proof sheet 70 to stand up toward the wearer's skin. An internal space 76 (see FIG. 3(b)) defined by the portion 75 and other members (the absorbent main body 2, etc.) opposed thereto, and an opening 77 opening inward in the longitudinal direction X. and a pocket portion 78 (see FIG. 1) is formed.
When the absorbent pad 1 (diaper 10) is worn, if the excrement excreted in the crotch portion M of the absorbent pad 1 migrates to the ventral portion F or the back portion R, it migrates from the crotch portion M. Since the excrement is accommodated in the internal space 76 of the pocket portion 78 through the opening 77, it does not move to the holder 11 to which the absorbent pad 1 is attached. Therefore, by providing the absorbent pad 1 with the pocket portion 78, the inconvenience of excrement adhering to the holder 11 is prevented, and the usable period of the holder 11 is lengthened.

The absorbent pad 1 has a pad-side fastening structure 8 that can be attached to and detached from the holder 11 in an end region in the longitudinal direction X. As shown in FIG. In this embodiment, as shown in FIG. 1 and the like, the pad-side fastening structure 8 is provided on the skin-facing surface (inner surface) of the absorbent pad 1 .

In this embodiment, the pad-side fastening structure 8 is fixed to the skin-facing surface of the second leak-proof sheet 70 that covers the skin-facing surface (such as the topsheet 3 ) of the absorbent body 2 . not directly fixed to the skin-facing surface of the If the absorbent pad 1 does not have the second leak-proof sheet 70 (second leak-proof cuff 7) and the pad-side fastening structure 8 is directly fixed to the skin-facing surface of the absorbent main body 2, When the excrement excreted to the crotch part M of the absorbent pad 1 moves to the ventral part F or the dorsal part R, the excrement adheres to the holder 11, shortening the usage period of the holder 11. - 特許庁is concerned. However, in the absorbent pad 1 of the present embodiment, the second leak-proof sheet 70 is interposed between the pad-side fastening structure 8 and the skin-facing surface of the absorbent body 2, so such concerns are eliminated. ing.

As the pad-side fastening structure 8, any structure that can be detachably fastened to the holder-side fastening structure 14 (see FIG. 5) of the holder 11 may be used. can be used. For example, one or both of the pad-side fastening structure 8 and the holder-side fastening structure 14 has an adhesive portion formed by applying an adhesive, and the pad-side fastening structure 8 is attached to the holder side via the adhesive portion. It may be detachably attached to the attachment structure 14 .

In this embodiment, a mechanical hook-and-loop fastener is employed as the fastening structure including the pad-side fastening structure 8 and the holder-side fastening structure 14 . The term "mechanical hook-and-loop fastener" as used here means a surface member (male member) with hook material (engagement member) consisting of hook-shaped projections arranged on one side, and a loop material consisting of pile-shaped projections on one side. An arranged face member (female member) refers to a set of fasteners. A specific example of the mechanical hook-and-loop fastener is Velcro (registered trademark).
Specifically, in this embodiment, the pad-side fastening structure 8 is a male member of a mechanical hook-and-loop fastener. It has the structure by which the said hook material was arrange|positioned. The holder-side fastening structure 14 is a female member of a mechanical hook-and-loop fastener, and is provided on the substrate and the non-skin-facing surface (outer surface) of the substrate, to which the pad-side fastening structure 8 can be attached. and a fastening region.

As one of the main features of the absorbent pad 1, as shown in FIGS. 2 and 4, pad-side fastening structures 8 extend in the horizontal direction Y and are intermittently arranged in plurality in the vertical direction X. points. As a result, for example, as shown in FIG. 5, when the absorbent pad 1 is worn with the absorbent pad 1 fixed to the holder 11 via the pad-side fastening structure 8, the wearer may stand up or sit down while wearing the pad. Since the pad-side fastening structure 8 can follow the movement of the wearer's body even if the wearer moves vigorously, an excessive load is less likely to be applied to the pad-side fastening structure 8, so that the absorbent pad 1 is worn. is effectively prevented from being separated from the holder 11.例文帳に追加

In this embodiment, as shown in FIGS. 2 and 4, the pad-side fastening structure 8 includes a longitudinally outermost fastening structure 8A located at the outermost position in the longitudinal direction X, and a vertical direction outermost fastening structure 8A. Also includes an inner fastening structure 8B located on the inner side in the longitudinal direction X. Both fastening structures 8A and 8B have a rectangular shape in a plan view, and their longitudinal directions are aligned with the horizontal direction Y, and extend over substantially the entire length of the absorbent pad 1 in the horizontal direction Y excluding both ends in the horizontal direction Y. Contiguous.
In this embodiment, the overall lengths in the horizontal direction Y of the plurality of pad-side fastening structures 8A and 8B intermittently arranged in the vertical direction X are the same. More specifically, both fastening structures 8A and 8B are They have the same shape and size in plan view. The term “same” as used herein includes the case where the compared total lengths are completely the same and the case where the lengths are slightly different but substantially the same. In the latter case, for example, the absolute value of the difference from the average value of the total lengths in the lateral direction of the plurality of pad-side fastening structures is preferably within 90% of the average value.
Outer ends in the longitudinal direction X out of both ends in the longitudinal direction X of the outermost fastening structure 8A extend in the longitudinal direction X from the outer ends 1X in the longitudinal direction of the absorbent pad 1 (absorbent main body 2). are arranged at positions spaced apart from each other by an interval L1. The inner fastening structure 8B is separated from the outermost fastening structure 8A in the vertical direction by a second elastic member 71 arranged in the non-fixed portion 75 of the second leak-proof sheet 70 at a position spaced in the vertical direction X by L2. are arranged outward in the longitudinal direction X.

From the viewpoint of further ensuring the effects of the characteristic configuration of the pad-side fastening structure 8 described above, it is preferable to set the dimensions of each part as follows.

As shown in FIG. In general, the absorbent body 5 has higher rigidity than other members of the absorbent pad 1, and the region of the absorbent pad 1 overlapping the absorbent body 5 in plan view is larger than the region not overlapping the absorbent body 5 in plan view. Although the high rigidity region has high rigidity and low flexibility, if the pad side fastening structure 8 is arranged only in the high rigidity region, the diaper 10 is fixed through the pad side fastening structure 8 during wearing. There is a concern that the holder 11 may be peeled off. On the other hand, in the present embodiment, the absorbent pad 1 can be fixed to the holder 11 via the longitudinally outermost fastening structure 8A, which is configured as described above and does not overlap the absorbent body 5 in a plan view. The inconvenience that the absorbent pad 1 is peeled off from the holder 11 is more effectively prevented. The present invention includes a form in which three or more pad-side fastening structures 8 are intermittently arranged in the longitudinal direction X in one end region of the absorbent pad 1 in the longitudinal direction X (see FIGS. 9 to 11). However, in such a configuration, it is preferable that only the longitudinally outermost fastening structure 8A does not overlap the absorbent body 5, and that the plurality of other inner fastening structures 8B overlap the absorbent body 5, respectively.

In this embodiment, as described above, as shown in FIGS. 2 and 3, the stretchable leg cuffs 65 are arranged at positions outside in the lateral direction Y of the side edges along the longitudinal direction X of the absorbent body 5, and in the longitudinal direction. Extending along X, at least one of the ventral side (abdominal portion F) and the dorsal side (dorsal portion R) of the leg cuff 65 extends in the longitudinal direction X of the pad-side fastening structure 8. It is preferably coincident in the longitudinal direction X with the inner edge or positioned outward in the longitudinal direction X beyond said inner edge. With such a configuration, together with the above-described characteristic configuration of the present invention, the predetermined effects of the present invention can be achieved more reliably.
The above-mentioned "stretching start position of the leg cuff 65" refers to the longitudinal direction X of the stretchable region (arrangement region of the standing portion 62) where the leg cuff forming elastic member 66 constituting the leg cuff 65 is arranged so as to be stretchable in the longitudinal direction X. Point to one end. The elastic region typically extends in the same direction over at least the entire length of the longitudinal direction X of the crotch portion M, and further extends to the ventral portion F and the dorsal portion R, respectively. Further, the above-mentioned "inner edge in the longitudinal direction X of the pad-side fastening structure 8" refers to a plurality of pad-side fastening structures intermittently arranged in the longitudinal direction X in the end region of the absorbent pad 1 in the longitudinal direction X. It refers to the inner edge in the longitudinal direction X of the attachment structure 8 positioned innermost in the longitudinal direction X (the pad-side fastening structure 8B in this embodiment). The term "inner edge" as used herein refers to the inner side of the pair of longitudinal direction X edges extending in the lateral direction Y of the pad-side fastening structure 8 (the side closer to the absorbent body 5). ). The pair of edges in the longitudinal direction X of the pad-side fastening structure 8 includes the inner edge and the outer edge positioned opposite to the inner edge.

Further, in this embodiment, as described above, as shown in FIGS. 2 and 3, the elastic first leak-proof cuff 6 ( Lateral leakage prevention cuff) is provided, and at least one of the ventral side (abdominal part F) and the dorsal side (dorsal part R), the expansion and contraction start position of the first leakage prevention cuff 6 is fixed on the pad side. It is preferably coincident in the longitudinal direction X with the inner edge in the longitudinal direction X of the structure 8 or lies outward in the longitudinal direction X beyond said inner edge. With such a configuration, together with the above-described characteristic configuration of the present invention, the predetermined effects of the present invention can be achieved more reliably.
The above-mentioned "stretching start position of the first leak-preventing cuff 6" refers to the stretchable region where the first elastic member 61 constituting the first leak-preventing cuff 6 is arranged so as to be stretchable in the vertical direction X (arrangement of the standing portion 62). region) in the vertical direction X. The elastic region typically extends in the same direction over at least the entire length of the longitudinal direction X of the crotch portion M, and further extends to the ventral portion F and the dorsal portion R, respectively.

6 to 12 illustrate layout patterns of pad-side fastening structures that can be employed in the present invention. In the embodiment of the absorbent pad to be described later, the configuration different from that of the absorbent pad 1 described above will be mainly described, and the configuration similar to that of the absorbent pad 1 will be given the same reference numerals and description thereof will be omitted. The description of the absorbent pad 1 is appropriately applied to configurations not particularly described in the embodiments of the absorbent pad described later. Further, in the embodiment of the absorbent pad to be described later, the ventral portion F will be described, but the description of the ventral portion F also applies to the dorsal portion R as appropriate unless otherwise specified.

In the absorbent pad 1A shown in FIG. 6, the total length in the horizontal direction Y (longitudinal direction) of the longitudinal outermost fastening structure 8A is larger than that of the other pad-side fastening structures 8 (inner fastening structures 8B). In the long point, it differs from the absorbent pad 1 (see FIG. 4) in which the overall length in the horizontal direction Y is the same among the plurality of pad-side fastening structures 8 . The absorbent pad 1A is particularly excellent in preventing the absorbent pad 1A constituting the diaper 10 from being easily peeled off from the holder 11 when the wearer of the diaper 10 (see FIG. 5) vigorously moves his/her legs.
The absorbent pad 1B shown in FIG. 7 is not configured as such in that the fastening structures 8A, 8B extend over the entire length of the absorbent pad 1B in the lateral direction Y, and the fastening structures 8A, 8B 8B is different from the absorbent pad 1 in that it is not arranged at both ends in the lateral direction Y of the absorbent pad. Even if the wearer of the diaper 10 moves violently and is subjected to an excessive load, the absorbent pad 1B that constitutes the diaper 10 does not peel off from the holder 11 starting from the end in the lateral direction Y. excellent in preventing
The absorbent pad 1C shown in FIG. 8 differs from the absorbent pad 1 in which the fastening structures 8A and 8B are linear in plan view in that the fastening structures 8A and 8B are curved in plan view. The absorbent pad 1C is particularly excellent in that it easily conforms to the wearer's body and is easily adhered to the holder used in combination.

The absorbent pad 1D shown in FIG. 9, the absorbent pad 1E shown in FIG. 10, and the absorbent pad 1F shown in FIG. They are common in that the attachment structures 8 (8A, 8B, 8C) are intermittently arranged in the vertical direction X. The fastening structure 8A is the outermost fastening structure in the vertical direction, and the fastening structures 8B and 8C are the inner fastening structures, and the length (width) of each fastening structure 8 in the vertical direction X is the same.
In the absorbent pad 1D, the interval between the fastening structures 8 adjacent to each other in the longitudinal direction X is shorter than the length (width) of the fastening structures 8 in the longitudinal direction X.
In the absorbent pad 1E, the interval between the fastening structures 8 adjacent to each other in the longitudinal direction X is shorter than the length (width) of the fastening structures 8 in the longitudinal direction X.
The absorbent pad 1F differs from the absorbent pads 1D and 1E in that the spacing between the fastening structures 8 adjacent to each other in the longitudinal direction X is different depending on the position. In the form shown in FIG. 11, the distance between the longitudinally outermost fastening structure 8A and the adjacent inner fastening structure 8B is located inward in the longitudinal direction X from the inner fastening structure 8B. longer than the interval with the inner fastening structure 8C.

The absorbent pad 1G shown in FIG. 12 is different from the absorbent pad 1 (see FIG. 4) in that the fastening structures 8A and 8B are provided with fastening inhibiting portions 81. FIG. The fastening inhibiting portion 81 is a portion where fastening of the holder-side fastening structure of the holder constituting the separate type absorbent article together with the absorbent pad 1G is prohibited. In the form shown in FIG. 12 , a plurality of circular fastening inhibiting portions 81 in plan view are intermittently arranged in the horizontal direction Y in each of the fastening structures 8A and 8B. The fastening inhibiting portion 81 can be formed, for example, by subjecting the pad-side fastening structure 8, which is a male member or female member of a mechanical hook-and-loop fastener, to compression processing such as embossing with or without heat. .
In general, when an absorbent pad is in an unused state such as when it is placed in a distribution process, it is often folded in half lengthwise with the skin-facing surface facing inward. If the absorbent pad 1 without the 81 is folded into such a state, the ventral portion F and the dorsal portion R facing each other will be joined together via the fastening structures 8A and 8B, resulting in It is necessary to take time and effort to undo this connection, and there is a risk that the absorbent pad will be damaged by forcibly undoing the connection. On the other hand, in the case of the absorbent pad 1G, since the fastening structures 8A and 8B are provided with the fastening inhibiting portions 81, even if the absorbent pad 1G is folded in half as described above, the abdominal portion F and the dorsal portion R are not separated. are difficult to combine, and the above-mentioned inconvenience is less likely to occur.

The present invention is not limited to the above embodiments, and can be modified as appropriate without departing from the scope of the present invention.
For example, the absorbent pad of the present invention may be provided with a disposal tape, an indicator of the wearer's excretion. The disposal tape is for maintaining the state of the rolled absorbent pad when the used absorbent pad is rolled into a small size and discarded. The disposal tape is typically provided on the non-skin-facing surface (outer surface) of the absorbent pad, and when used, the absorbent pad is rolled up in the longitudinal direction with the skin-facing surface (inner surface) facing inward. , so as to straddle one longitudinal end exposed on the outer surface in the same direction, thereby maintaining the rolled state of the absorbent pad. In addition, the indicator is used for the purpose of notifying the replacement time of the absorbent pad, and typically, it is designed to visually change such as by changing color when it comes into contact with urine. The change in color of the indicator is visually visible from the outside of the absorbent pad. As the disposal tape and indicator, those conventionally used in this type of absorbent article can be used without particular limitation.

In the above embodiment, the pad-side fastening structure 8 is provided on the skin-facing surface (inner surface) of the absorbent pad 1, but in the present invention, it is provided on the non-skin-facing surface (outer surface) of the absorbent pad 1. In that case, for example, the pad-side fastening structure 8 can be fixed to the non-skin-facing surface of the backsheet 4 .

In the above embodiment, the pad-side fastening structure 8 is the male member of the mechanical hook-and-loop fastener, and the holder-side fastening structure 14 is the female member of the mechanical hook-and-loop fastener. The fastening structure 8 may be a female member of a mechanical hook-and-loop fastener, and the holder-side fastening structure 14 may be a male member of a mechanical hook-and-loop fastener.
