Description

[Technical field]

[0001] The present invention relates to an absorbent pad which is used by being detachably fixed to a holder which is attached around the waist of a wearer. [Background technology]

[0002] As one type of absorbent article such as disposable diapers, a separate type is known which includes an absorbent pad for absorbing and retaining body fluids such as urine, and a holder which is annularly attached around the waist of a wearer and holds the absorbent pad arranged in the crotch area of ​​the wearer, and the absorbent pad is configured to be freely attached and detached to the holder. In conventional separate type absorbent articles, as described in Patent Documents 1 and 2, a pad side fastening structure which is attachable and detachable to the fastening structure (holder side fastening structure) of the holder is provided at the end area in the vertical direction (the direction corresponding to the front-rear direction of the wearer) of the absorbent pad. In the absorbent pad described in Patent Document 1, a plurality of band-shaped pad side fastening structures extending in the horizontal direction are intermittently arranged in the vertical direction on each of the abdominal side part and the back side part (see FIG. 2). In the absorbent pad described in Patent Document 2, four pad side fastening structures having a square shape in plan view are intermittently arranged in both the vertical direction and the horizontal direction on each of the vertical end areas of the abdominal side part and the back side part (see FIG. 3).

[0003] [Patent Document 1] JP 2002-641 A [Patent Document 2] JP 2004-329590 A Summary of the Invention [Problem to be solved by the invention]

[0004] There is a problem that a wearer who is wearing an absorbent article may remove the absorbent article at a time when it should not be removed, and excrete in a place other than the toilet with the absorbent article removed, soiling the excretion place and the items there. For example, a care recipient such as an infant or a bedridden elderly person may feel an unpleasant sensation such as tightness of the diaper or itching in the crotch area while sleeping while wearing a diaper, and unconsciously reach down to the lower abdomen to remove the diaper, and then excrete feces or the like with the diaper removed, soiling the bedding or the like. Such an incident is often repeated day after day, and in such a case, a great burden is imposed on the person who cleans up the excreta (the guardian of the infant, the caregiver, etc.). As a method for solving this problem in a separate type absorbent article, a method is considered in which the fastening force of the absorbent pad to the holder via the pad side fastening structure is increased to make it difficult for the wearer to remove the absorbent pad from the holder. However, with this method, there is a risk that third parties other than the wearer (such as the parent or caregiver of the infant) may have difficulty removing the absorbent pad from the holder.

[0005] Therefore, an object of the present invention is to provide a technique that can prevent the wearer from removing the absorbent pad from the holder, while allowing a third party to smoothly remove the absorbent pad from the holder. [Means for solving the problem]

[0006] The present invention is an absorbent pad which comprises a top sheet which is positioned closer to the wearer's skin when worn, a back sheet which is positioned farther from the wearer's skin, and an absorbent body which is positioned between the top sheet and the back sheet, has a vertical direction which corresponds to the front-to-back direction passing through the wearer's crotch and a horizontal direction which is perpendicular to the vertical direction, and can be used by being removably fixed to a holder which is worn in a ring shape around the wearer's waist. One embodiment of the absorbent pad of the present invention has, in the end region in the longitudinal direction, a pad-side fastening structure that is detachable from the holder. In one embodiment of the absorbent pad of the present invention, the pad side fastening structure has a fastening force against the holder that varies partially in the vertical direction, with the fastening force being stronger in the portion located on the outer side in the vertical direction than in the portion located on the inner side in the vertical direction. Other features, advantages and embodiments of the present invention are described below. Effect of the Invention

[0007] According to the absorbent pad of the present invention, removal of the absorbent pad from the holder by the wearer can be prevented, while a third party can smoothly remove the absorbent pad from the holder. [Brief description of the drawings]

[0009] The present invention will be described below based on preferred embodiments with reference to the drawings. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. The drawings are basically schematic, and the ratio of each dimension may differ from the actual one.

[0010] 1 to 4 show an absorbent pad 1 which is one embodiment of the absorbent pad of the present invention. FIG. 5 shows 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 on a wearer as an example of use of the absorbent pad of the present invention. The diaper 10 is one embodiment of the absorbent article of the present invention, that is, an absorbent article including 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 an absorbent pad 1 and a holder 11 joined together via a pad-side fastening structure 8 and a holder-side fastening structure 14, and has a waist opening WH of the holder 11 and a pair of leg openings LH, LH defined by a lower end of the holder 11 in a height direction HD and both side edges of the absorbent pad 1 along a longitudinal direction (vertical direction X to be described later). The holder 11 is not a component of the absorbent pad 1.

[0011] The diaper 10, which is a separate type absorbent article, reduces the burden on the environment compared to conventional non-separate type absorbent articles because the absorbent pad 1 and the holder 11 can be freely connected and separated via the fastening structures 8, 14. That is, when a conventional non-separate type absorbent article in which the part corresponding to the wearer's waist (part corresponding to the holder) and the part corresponding to the wearer's crotch (part corresponding to the absorbent pad) are inseparably integrated, is disposed of after use, even if the part corresponding to the holder is not soiled, it has to be disposed of together with the part corresponding to the absorbent pad which is soiled with excrement. However, with the diaper 10, it is only necessary to replace only the absorbent pad 1 with a new one while leaving the holder 11 as it is, so that the amount of waste disposal and carbon dioxide emissions are reduced compared to non-separate type absorbent articles, and this contributes to reducing the burden on the environment. In addition, since the absorbent pad 1 is removably fixed to the holder 11 while the diaper 10 is being worn, the absorbent pad 1 can be easily replaced with a new one, and the burden of replacing the diaper 10 is significantly reduced compared to conventional non-separate type absorbent articles.

[0012] The absorbent pad 1 is used by being detachably fixed to a holder 11 that is attached in a ring shape around the waist of a wearer. Here, the holder 11 will be briefly described with reference to FIG. 5. The holder 11 is attached in a ring shape around the waist of a wearer and holds the absorbent pad 1 in a state where it is attached to the wearer, and 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 a ventral side portion 11F arranged on the ventral side (front side) of the wearer and a back side portion 11R arranged on the back side (rear side) of the wearer, and is provided with a holder main body portion 12 that constitutes the main body of the holder 11. The holder main body portion 12 is mainly composed of a sheet-like member such as a nonwoven fabric, and is typically composed of a laminated structure of an outer layer sheet that forms a non-skin facing surface (outer surface) of the holder main body portion 12 and an inner layer sheet that forms a skin facing surface (inner surface) of the holder main body portion 12. The holder 11 is annular in shape, with both longitudinal ends of the holder body 12 of each of the ventral portion 11F and the rear portion 11R joined together by known joining means such as fusion or adhesive, and has a pair of joining parts S, S between the ventral portion 11F and the rear portion 11R, and a waist opening WH. The joining parts S correspond to side seal parts in a general non-separate type pants-type disposable diaper. The holder body 12 of each of the ventral portion 11F and the rear portion 11R has a plurality of elastic members 13 arranged intermittently in the height direction HD so as to be stretchable in a direction perpendicular to the height direction HD, thereby making the holder 11 stretchable in the circumferential direction CD. A holder side fastening structure 14 is arranged on the non-skin facing surface (outer surface) of the holder body 12, and the absorbent pad 1 can be detachably fastened to the holder 11 by fastening the pad side fastening structure 8 of the absorbent pad 1 to the holder side fastening structure 14. Because the holder 11 does not include an absorbent that absorbs and retains moisture, if washable materials are used as components of the holder main body 12, the holder 11 can be washed and reused. The fact that the holder 11 is washable leads to a reduction in the amount of waste and carbon dioxide emissions, and can contribute to reducing the burden on the environment. Holder 11 is merely one embodiment of a holder to which the absorbent pad of the present invention can be applied, and any holder to which the absorbent pad of the present invention can be applied may have a holder-side fastening structure that can be fastened to the pad-side fastening structure of the absorbent pad, and is not limited to holder 11. For example, a holder to which the absorbent pad of the present invention can be applied may be annular when attached to the body, and may be annular in advance like holder 11, or may be a long strip before being attached to the body, and may be annular when attached by engaging one end and the other end in the longitudinal direction.

[0013] In this specification, the term "skin-facing surface" refers to the surface of a worn article such as an absorbent article, holder, or absorbent pad, or a component thereof (e.g., the absorbent body of an absorbent pad), which faces the skin of the wearer when the worn article is worn, and the term "non-skin-facing surface" refers to the surface of the worn article or a component thereof, which faces the side opposite the skin when the worn article is worn.

[0014] The absorbent pad 1 will now be described in detail. The absorbent pad 1 comprises a top sheet 3 located closer to the wearer's skin when worn, a back sheet 4 located farther from the wearer's skin, and an absorbent body 5 located between the sheets 3, 4, and has a longitudinal direction X and a lateral direction Y perpendicular to the longitudinal direction X. The longitudinal direction X of the absorbent pad 1 corresponds to the front-to-rear direction passing through the crotch of the wearer and corresponds to 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.

[0015] As shown in Fig. 2, the absorbent pad 1 has a crotch portion M arranged in the crotch portion of the wearer, a ventral portion F arranged on the ventral side (front side) of the wearer relative to the crotch portion M, and a back portion R arranged on the back side (rear side) of the wearer relative to the crotch portion M. The crotch portion M is located in the center of the absorbent pad 1 in the vertical direction X, and includes an excretory portion facing portion (not shown) that faces an excretory portion such as the penis of the wearer when worn. As shown in Fig. 5, when the absorbent pad 1 is properly fastened to the holder 11, the ventral portion F of the absorbent pad 1 includes a portion overlapping the ventral portion 11F of the holder 11, and the back portion R of the absorbent pad 1 includes a portion overlapping the back portion 11R of the holder 11, but the crotch portion M of the absorbent pad 1 does not overlap the holder 11. In this embodiment, the absorbent pad 1 has a rectangular shape in a plan view in the unfolded and maximally extended state as shown in Fig. 2, and is formed symmetrically on one side and the other side with respect to a lateral center line CLy. The lateral center line CLy is an imaginary straight line extending in the vertical direction X, dividing the absorbent pad 1 in the unfolded and maximally extended state as shown in Fig. 2 in half in the lateral direction Y.

[0016] In this specification, the term "unfolded and maximum stretched state" refers to a state in which a wearing article such as an absorbent article, a holder, an absorbent pad, etc. is spread out flat to an unfolded state, and the elastic members of each part of the wearing article in the unfolded state are stretched to their maximum extent to be the same as the designed dimensions, i.e., the dimensions when the article is spread out flat in a state completely free of the influence of the elastic members. In the case of an absorbent article having a side seal portion such as the joint portion S of the holder 11 described above, the absorbent article is separated at the side seal portion and spread out flat to the unfolded state.

[0017] In this embodiment, the absorbent pad 1 comprises an absorbent body 2 including a top sheet 3, a back sheet 4 and an absorbent body 5, a pair of first leakage preventing cuffs 6, 6 arranged along both sides of the absorbent body 2 in the longitudinal direction X, and a pair of second leakage preventing cuffs 7, 7 arranged at both end regions in the longitudinal direction X of the absorbent body 2. The first leakage preventing cuffs 6 are located at end regions in the transverse direction Y to prevent leakage of body waste outward in the transverse direction Y, and can be called "lateral leakage preventing cuffs". The second leakage preventing cuffs 7 are located at end regions in the longitudinal direction X to prevent leakage of body waste outward in the longitudinal direction X, and can be called "vertical leakage preventing cuffs".

[0018] The absorbent body 2 constitutes the main body of the absorbent pad 1 and has the function of absorbing and retaining excrement such as urine. In this embodiment, the absorbent body 2 has a long shape in the vertical direction X, and extends in the vertical direction X from the ventral side part F to the dorsal side part R with its longitudinal direction coinciding with the vertical direction X. The top sheet 3 forms the skin-facing surface of the absorbent body 2 and can come into contact with the skin of the wearer when worn. The back sheet 4 forms the non-skin-facing surface of the absorbent body 2. The top sheet 3 contacts the skin-facing surface of the absorbent body 5 to cover the entire area, and the back sheet 4 contacts the non-skin-facing surface of the absorbent body 5 to cover the entire area. The absorbent body 5 is configured to include an absorbent core 51 capable of absorbing and retaining bodily fluids, and a core wrap sheet 52 that covers the outer surface including the skin-facing surface and non-skin-facing surface of the absorbent core 51. 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 not be included. The above-mentioned plurality of members 3, 4, 5 constituting the absorbent main body 2 are joined together by a known joining means such as an adhesive.

[0019] As the constituent members of the absorbent body 2, those which are usually used in this type of absorbent article can be used without any particular limitation. A liquid-permeable sheet can be used as the topsheet 3, and examples thereof include nonwoven fabrics produced by various manufacturing methods, perforated nonwoven fabrics which are nonwoven fabrics having through-holes, uneven nonwoven fabrics in which an uneven shape is imparted to at least one surface of the nonwoven fabric, and perforated films which are resin films having through-holes. The topsheet 3 may have a single-layer structure, or a laminate structure in which one or more types of layers are laminated. The back sheet 4 may be a liquid-impermeable or liquid-slightly permeable or water-repellent sheet, and examples thereof include nonwoven fabric, resin film, and laminates of resin film and nonwoven fabric. The absorbent core 51 typically contains a water-absorbing material as a main component, and contains one or more types of water-absorbing material selected from a fiber material such as wood pulp and a water-absorbing polymer. 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 transverse direction Y, or the thickness direction. The absorbent core 51 may be a stacking type mainly made of a fiber material, or a sheet type including a fiber sheet and water-absorbing polymer particles fixed thereto. The stacking type absorbent core can be manufactured, for example, by using a known stacking device equipped with a stacking drum. The sheet type absorbent core has a configuration in which water-absorbing polymer particles are interposed between two opposing fiber sheets. 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 a recess having an opening on 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 a partially different density, and in this case, the relatively high-density portion may be a portion formed by a compression process such as embossing.

[0020] 2 and 3, the first leakproof cuff 6 comprises a first leakproof sheet 60 which constitutes the main body of the first leakproof cuff 6, and a first elastic member 61 which is fixed to the first leakproof sheet 60 and is stretchable in the vertical direction X. The first leakproof sheet 60 forms part of the skin-facing surface of the absorbent pad 1. The first leakproof sheet 60 is folded back in the horizontal direction Y, and the first elastic member 61 is disposed between the opposing first leakproof sheets 60, 60 by the folding back. The first leakproof cuff 6 (first leakproof sheet 60) is disposed continuously along the side portion of the absorbent main body 2 along the vertical direction X, over substantially the entire length of the absorbent main body 2 in the vertical direction X. The first leakproof cuff 6 has, at least in the crotch portion M, an upstanding portion 62 that stands toward the wearer's skin when the absorbent pad 1 (diaper 10) is worn. The upstanding portion 62 stands toward the wearer's skin from a fixed portion 63 as its starting point. The upstanding portion 62 is a portion of the first leakproof sheet 60 that is not fixed to another member. The fixed portion 63 is a portion of the first leakproof sheet 60 that is fixed to another member by a known joining means such as an adhesive or fusion, and in the illustrated embodiment, the other member is the topsheet 3. At both end regions in the longitudinal direction X of the first leakproof cuff 6, there are formed upright inhibition sections 64, which are sections where the uprighting of the first leakproof sheet 60 is inhibited. The upright inhibition sections 64 are formed in the ventral side section F and the dorsal side section R, and the section of the first leakproof cuff 6 along the longitudinal direction X sandwiched between the upright inhibition sections 64, 64 is the upright section 62. The upright inhibition section 64 is a section of the first leakproof sheet 60 at the same position in the transverse direction Y as the upright section 62, which is joined to another member such as the top sheet 3 and / or a section of the first leakproof sheet 60 other than the upright section 62 by a known joining means such as an adhesive or fusion. Since a pair of rising inhibition parts 64, 64 are formed at both end regions in the longitudinal direction X of the first leakage preventing cuff 6, when the absorbent pad 1 (diaper 10) is worn, the rising part 62, which is a part of the first leakage preventing cuff 6 sandwiched between the rising inhibition parts 64, 64, rises toward the wearer's skin from the fixed part 63 as a rising starting point due to contraction of the first elastic member 61. This prevents excrement such as urine excreted by the wearer from leaking outward in the lateral direction Y from the absorbent pad 1, which is known as lateral leakage. As the first leakproof sheet 60, any material used as a leakproof cuff in this type of absorbent article can be used without any particular limitation, such as a single-layer or multi-layer water-repellent nonwoven fabric, a laminate of a resin film and a nonwoven fabric, etc. Furthermore, there is no particular limitation on the number of first elastic members 61 arranged, and there may be one or more.

[0021] In this embodiment, as shown in Fig. 3, leg cuffs 65 are provided at leg edges of the absorbent pad 1 corresponding to the circumference of the wearer's legs. The leg edges typically include both side edges along the longitudinal direction X of the absorbent pad 1 in the crotch portion M. The leg cuffs 65 are configured to include a first leakproof sheet 60 constituting the first leakproof cuffs 6 and a leg-cuff-forming elastic member 66. More specifically, of both side edges along the longitudinal direction X of the first leakproof sheet 60, one (the inner edge) is the above-mentioned standing portion 62, and the other (the outer edge) is fixed to other members (the top sheet 3 and the back sheet 4 in this embodiment) outside the lateral direction Y of the absorbent body 5, and the leg-cuff-forming elastic member 66 extending in the longitudinal direction X is fixed to the fixed portion of the first leakproof sheet 60 to the other member so as to be stretchable in the same direction, thereby forming the leg cuffs 65. The leg cuff-forming elastic members 66 are disposed at least at the side edges of the absorbent pad 1 along the longitudinal direction X in the crotch portion M. When the absorbent pad 1 is in a worn or natural state, the contraction of the leg cuff-forming elastic members 66 forms substantially continuous leg gathers in the longitudinal direction X at the leg edges.

[0022] 2 and 4, the second leakproof cuff 7 includes a second leakproof sheet 70 which constitutes the main body of the second leakproof cuff 7, and a second elastic member 71 which is fixed to the second leakproof sheet 70 and is stretchable in the lateral direction Y. The second leakproof sheet 70 forms at least a part of the skin-facing surface of the ventral part F or dorsal part R of the absorbent pad 1. As the second leakproof sheet 70, a sheet similar to the first leakproof sheet 60 can be used. In this embodiment, the configuration of the second leakage preventing cuff 7 is the same in the ventral portion F and the dorsal portion R, and unless otherwise specified, the description of the second leakage preventing cuff 7 in one of the ventral portion F and the dorsal portion R also applies, as appropriate, to the other second leakage preventing cuff 7.

[0023] In this embodiment, the second leakproof sheet 70 has a rectangular shape in a plan view, and covers substantially the entire area of ​​the skin-facing surface of the end region in the longitudinal direction X of the absorbent main body 2. As shown in Fig. 4, of both ends in the longitudinal direction X of the second leakproof sheet 70, a longitudinal outer end 70X1 located outward in the longitudinal direction X coincides with the longitudinal end (the longitudinal end on the ventral side F side or the dorsal side R side) of the absorbent main body 2 on which the second leakproof sheet 70 is arranged, and both ends 70Y, 70Y in the transverse direction Y of the second leakproof sheet 70 coincide with both ends in the transverse direction Y of the absorbent main body 2 (both side edges along the longitudinal direction X). That is, in this embodiment, the longitudinal outer end 70X1 of the second leakproof sheet 70 coincides with the longitudinal outer end 1X of the absorbent pad 1, and the transverse end 70Y of the second leakproof sheet 70 coincides with the transverse outer end (side edge along the longitudinal direction X) 1Y of the absorbent pad 1. Of both ends in the longitudinal direction X of the second leak-proof sheet 70, an inner longitudinal end 70X2 located on the inner side in the longitudinal direction X extends parallel to the lateral direction Y.

[0024] As shown in Fig. 4, the second leakproof sheet 70 has a fixed portion 72 (hatched area in Fig. 4) that is fixed to another member, and a non-fixed portion 75 that is not fixed to another member. The "other member" to which the second leakproof sheet 70 is fixed is a member that is disposed opposite the second leakproof sheet 70, such as the top sheet 3 or the first leakproof sheet 60. The second leakproof sheet 70 and the other member are joined by fixing means 79 (see Fig. 3(a)). The arrangement area of ​​the fixing means 79 is the same as the fixing portion 72 (hatched area in Fig. 4). There are no particular limitations on the fixing means 79, and any known fixing means such as adhesive or fusion can be used. The fixed portion 72 includes a continuous fixed portion 73 in which the fixed portion between the second leakproof sheet 70 and other members extends continuously over the entire length of the absorbent body 2 in the horizontal direction Y, and a discontinuous fixed portion 74 located inward in the vertical direction X from the continuous fixed portion 73 and adjacent to the continuous fixed portion 73, in which the fixed portion between the second leakproof sheet 70 and other members exists intermittently in the horizontal direction Y, and a non-fixed portion 75 is located between a pair of discontinuous fixed portions 74, 74 adjacent to each other in the horizontal direction Y.

[0025] As shown in Fig. 4, a second elastic member 71 extending in the horizontal direction Y is arranged to be stretchable in the horizontal direction Y at an end portion in the vertical direction X on the vertical inner end 70X2 side of the second leakproof sheet 70 (an inner end portion in the vertical direction X). In the present embodiment, the second elastic member 71 is arranged to straddle a pair of discontinuous fixed portions 74, 74 and a non-fixed portion 75 therebetween in the horizontal direction Y, but the arrangement pattern of the second elastic member 71 is not particularly limited in the present invention. For example, in the embodiment shown in Fig. 4, the second elastic member 71 may be arranged only in an area overlapping with the non-fixed portion 75 in a plan view, and may not extend to a pair of discontinuous fixed portions 74, 74 on both sides of the non-fixed portion 75 in the horizontal direction Y. Alternatively, the discontinuous fixed portion 74 may not be arranged in an area overlapping with the second elastic member 71 and its virtual extension line in a plan view (an area at the same position as the second elastic member 71 in the vertical direction X). There is no particular restriction on the number of second elastic members 71 arranged, and there may be one or more. In this embodiment, the inner end portion in the longitudinal direction X of the second leakproof sheet 70 is folded back towards the skin-facing side or the non-skin-facing side of the second leakproof sheet 70, and two second elastic members 71 are arranged between the opposing second leakproof sheets 70, 70 formed by the folding back. When the absorbent pad 1 is worn or in its natural state, the 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, and an internal space 76 (see Figure 3(b)) is formed between the standing non-fixed portion 75 and another member (such as the absorbent main body 2) facing it, and a pocket portion 78 (see Figure 1) is formed having an opening 77 that opens inward in the vertical direction X. When the absorbent pad 1 (diaper 10) is worn, if excrement excreted in the crotch portion M of the absorbent pad 1 transfers to the ventral portion F or the dorsal portion R, the excrement transferring from the crotch portion M is received in the internal space 76 of the pocket portion 78 through the opening 77, and does not transfer to the holder 11 to which the absorbent pad 1 is attached. Therefore, by providing the pocket portion 78 to the absorbent pad 1, the inconvenience of excrement adhering to the holder 11 is prevented, and the usable period of the holder 11 is extended.

[0026] The absorbent pad 1 has a pad-side fastening structure 8 at an end region in the vertical direction X that is detachable from the holder 11. In this embodiment, as shown in Fig. 1 etc., the pad-side fastening structure 8 is provided on the skin-facing surface (inner surface) of the absorbent pad 1.

[0027] In this embodiment, the pad-side fastening structure 8 is divided into a plurality of fastening elements 8A, 8B in the vertical direction X as shown in Figs. 2 and 4, and the plurality of fastening elements 8A, 8B are arranged intermittently in the vertical direction X. More specifically, the pad-side fastening structure 8 of this embodiment includes a fastening element 8A (outermost fastening structure 8A) located at the outermost position in the vertical direction X, and a fastening element 8B (inner fastening structure 8B) located on the inner side of the fastening element 8A in the vertical direction X. Each of the fastening elements 8A and 8B has a rectangular shape in a plan view, and is continuous over substantially the entire length of the absorbent pad 1 in the horizontal direction Y with its longitudinal direction aligned with the horizontal direction Y, excluding both ends in the horizontal direction Y. In this embodiment, the total length in the horizontal direction Y of the fastening elements 8A, 8B intermittently arranged in the vertical direction X is the same as each other, and more specifically, the fastening elements 8A, 8B have the same shape and size as each other in a plan view. Note that "same" here includes a case where the compared total lengths are completely the same as each other, and a case where they are slightly different but substantially the same. In the latter case, for example, it is preferable that the absolute value of the difference from the average value of the total lengths in the horizontal direction of the fastening elements is within 90% of the average value. In this specification, unless otherwise specified, the description of the pad side fastening structure also applies to the fastening elements as appropriate, and the description of the fastening elements also applies to the pad side fastening structure as appropriate.

[0028] Of both ends in the vertical direction X of the fastening element 8A, the end on the outer side in the vertical direction X is disposed at a distance L1 in the vertical direction X from the vertical outer end 1X of the absorbent pad 1 (absorbent main body 2). The fastening element 8B is disposed at a distance L2 in the vertical direction X from the fastening element 8A and further outward in the vertical direction X than the second elastic member 71 disposed in the non-fixed portion 75 of the second leakproof sheet 70. The distance L1 (see FIG. 4) between the fastening element 8A and the outer end 1X of the absorbent pad 1 in the longitudinal direction is preferably 30 mm or less, more preferably 25 mm or less. In the present invention, the distance L1 may be zero. That is, in the present invention, the outer end in the longitudinal direction X of the pad-side fastening structure 8 (fastening element 8A) may coincide with the outer end 1X of the absorbent pad 1 in the longitudinal direction. The distance L2 (see FIG. 4) between adjacent fastening elements 8A, 8B in the longitudinal direction X is preferably 1 mm or more, more preferably 3 mm or more, and preferably 50 mm or less, more preferably 40 mm or less. The present invention includes a configuration in which three or more fastening elements are intermittently arranged in the longitudinal direction X in one end region in the longitudinal direction X of the absorbent pad (see FIG. 7), and it is preferable that the distance between adjacent fastening elements in the longitudinal direction X in such a configuration is set within the above range. Note that the present invention also includes a configuration in which the distance L2 is zero.

[0029] In this embodiment, the pad-side fastening structure 8 is fixed to the skin-facing surface of the second leakproof sheet 70 that covers the skin-facing surface (top sheet 3, etc.) of the absorbent body 2, and is not directly fixed to the skin-facing surface of the absorbent body 2. If the absorbent pad 1 does not have the second leakproof sheet 70 (second leakproof cuff 7) and the pad-side fastening structure 8 is directly fixed to the skin-facing surface of the absorbent body 2, there is a concern that when excrement excreted in the crotch part M of the absorbent pad 1 moves to the abdominal part F or the dorsal part R, the excrement will adhere to the holder 11, shortening the period of use of the holder 11. However, in the absorbent pad 1 of this embodiment, the second leakproof sheet 70 is interposed between the pad-side fastening structure 8 and the skin-facing surface of the absorbent body 2, so that such a concern is eliminated.

[0030] The pad-side fastening structure 8 may be any known detachable fastening structure as long as it can be detachably attached to the holder-side fastening structure 14 (see FIG. 5) of the holder 11. For example, one or both of the pad-side fastening structure 8 and the holder-side fastening structure 14 may have an adhesive part formed by applying an adhesive, and the pad-side fastening structure 8 may be detachably attached to the holder-side fastening structure 14 via the adhesive part.

[0031] In this embodiment, a mechanical hook-and-loop fastener is used as the fastening structure including the pad-side fastening structure 8 and the holder-side fastening structure 14. The "mechanical hook-and-loop fastener" here refers to a fastener that is a set of a surface member (male member) having a hook material (engagement member) made of hook-shaped protrusions arranged on one surface, and a surface member (female member) having a loop material made of pile-shaped protrusions arranged on one surface. A specific example of a mechanical hook-and-loop fastener is Magic Tape (registered trademark). Specifically, in this embodiment, the pad-side fastening structure 8 is a male member of a mechanical hook-and-loop fastener, and typically has a configuration in which a large number of the hook members are arranged on the surface of a base material made of a resin film, a woven fabric, a nonwoven fabric, etc. Also, the holder-side fastening structure 14 is a female member of a mechanical hook-and-loop fastener, and includes a base material and a fastening region provided on the non-skin-facing surface (outer surface) of the base material, to which the pad-side fastening structure 8 can be fastened.

[0032] One of the main features of the absorbent pad 1 is that the fastening force of the pad-side fastening structure 8 to the holder 11 varies partially in the vertical direction X, and the fastening force is stronger in the portion located on the outer side of the vertical direction X than in the portion located on the inner side of the vertical direction X. In this embodiment, as shown in FIG. 2 etc., as described above, the pad-side fastening structure 8 includes a fastening element 8A located at the outermost position in the vertical direction X and a fastening element 8B located on the inner side in the vertical direction X than the fastening element 8A. Due to the above-mentioned characteristics, the fastening element 8A has a stronger fastening force to the holder 11 than the fastening element 8B. The portion of the pad-side fastening structure 8 located on the outer side in the longitudinal direction X, represented by the fastening element 8A, is usually the portion that is first picked up with the fingers and peeled off from the holder 11 when the wearer of the diaper 10 takes off the diaper 10 by himself, and the fastening force of this portion to the holder 11 is stronger than that of the other portions (portions located on the inner side in the longitudinal direction X) of the pad-side fastening structure 8, thereby preventing the wearer from removing the absorbent pad from the holder as described above. On the other hand, the portion of the pad-side fastening structure 8 located on the inner side in the longitudinal direction X, represented by the fastening element 8B, has a relatively weak fastening force to the holder 11, so that when a third party other than the wearer takes off the diaper 10, the absorbent pad 1 can be peeled off from this portion to smoothly take off the diaper 10.

[0033] In this embodiment, as shown in Figure 2, the pad side fastening structure 8 (fastening elements 8A, 8B) is continuous in the horizontal direction Y. Therefore, compared to the case where the pad side fastening structure is intermittently arranged in the horizontal direction, as described in, for example, Figure 1 of Patent Document 2, the fastening force of the absorbent pad to the holder is stronger, and the inconvenience of the absorbent pad being unintentionally peeled off from the holder can be more effectively prevented. Here, "the pad side fastening structure is continuous in the horizontal direction" includes 1) a form in which a single pad side fastening structure extends continuously in the horizontal direction (see Fig. 2, Fig. 4, etc.) as well as 2) a form in which multiple pad side fastening structures are intermittently arranged in the horizontal direction (see Fig. 8), where the condition for the form 2) is that the interval between multiple adjacent pad side fastening structures in the horizontal direction is very narrow, and therefore the single pad side fastening structure can be essentially regarded as being continuous in the horizontal direction. The interval in the form 2) is preferably 20 mm or less, more preferably 10 mm or less.

[0034] In the present invention, the method of partially varying the fastening force of the pad side fastening structure to the holder as described above is not particularly limited, and various methods can be adopted within the scope of the invention without departing from the spirit of the invention. As an example of the method, there is a method in which the area of ​​a portion located on the outer side in the vertical direction X of the pad-side fastening structure is made different from that of a portion located on the inner side in the vertical direction X, i.e., the relationship of "area of ​​the portion located on the outer side in the vertical direction X>area of ​​the portion located on the inner side in the vertical direction X" is established (hereinafter, also referred to as "Method A"). The absorbent pads in Figs. 6 to 8 described later employ the method A. Another example of the method is to make the fastening force per unit area different between the part located on the outer side of the vertical direction X of the pad-side fastening structure 8 and the part located on the inner side, in other words, to make the configuration of the fastening structure different (hereinafter, also referred to as "Method B"). The absorbent pads shown in Figs. 9 to 11, which will be described later, employ the method B. In the present invention, in order to partially vary the fastening force of the pad-side fastening structure to the holder, both of the methods A and B can be adopted.

[0035] 2 and 4, in the plan view of the absorbent pad 1, a portion (fastening element 8A) located on the outer side in the vertical direction X of the pad-side fastening structure 8 does not overlap with the absorbent body 5 (absorbent core 51), and a portion (fastening element 8B) located on the inner side in the vertical direction X of the pad-side fastening structure 8 overlaps with the absorbent body 5 (absorbent core 51). In general, the absorbent body 5 (absorbent core 51) has higher rigidity than other members of the absorbent pad 1, and a region of the absorbent pad 1 that overlaps with the absorbent body 5 in a plan view is a high-rigidity region that has higher rigidity and lower flexibility than a region that does not overlap with the absorbent body 5 in a plan view. If the pad-side fastening structure 8 is disposed only in the high-rigidity region, there is a concern that the holder 11 fixed via the pad-side fastening structure 8 may come off while the diaper 10 is being worn. In contrast, in this embodiment, which is configured as described above, the absorbent pad 1 can be fixed to the holder 11 via the outermost vertical fastening structure 8A that does not overlap the absorbent body 5 in a plan view, and therefore the absorbent pad 1 is more effectively prevented from peeling off from the holder 11. The present invention includes a configuration in which three or more pad side fastening structures 8 are intermittently arranged in the vertical direction X in one end region in the vertical direction X of the absorbent pad 1 (see FIG. 7 ), and in such a configuration, it is preferable that only the outermost vertical fastening structure 8A does not overlap the absorbent body 5, and the other multiple inner fastening structures 8B each overlap the absorbent body 5.

[0036] In this embodiment, the pad-side fastening structure 8 includes a plurality of fastening elements 8A, 8B arranged at intervals in the vertical direction X. When a plurality of fastening elements are arranged at intervals in the vertical direction X in this manner, it is preferable that an elastic member is not arranged in a stretchable state in the region between the plurality of fastening elements adjacent to each other in the vertical direction X. In this embodiment, it is preferable that an elastic member is not arranged in a stretchable state in the region between the fastening element 8A and the fastening element 8B. In other words, it is preferable that the region between the fastening element 8A and the fastening element 8B is not given elasticity by the elastic member arranged in the region. The term "elasticity" as used herein refers to a property that can be stretched and returns to a length of 110% or less of the original length when a force is released from a state in which the fastening element is stretched 50% of its original length (a state in which the fastening element is stretched 150% of its original length, i.e., 1.5 times its original length). It is preferable that the region between the fastening elements 8A, 8B adjacent to each other in the vertical direction X does not have such a property. As a result, for example, when the diaper 10 shown in Figure 5 is being worn, the intermittently arranged fastening elements 8A, 8B each easily follow the movement of the wearer's body, thereby more effectively preventing the absorbent pad 1 from peeling off from the holder 11.

[0037] 2 and 3, the stretchable leg cuffs 65 extend along the longitudinal direction X at a position outward in the transverse direction Y from the side edges along the longitudinal direction X of the absorbent body 5, and it is preferable that the stretch start position of the leg cuffs 65 on at least one of the ventral side (ventral portion F) and the dorsal side (dorsal portion R) coincides with the inner edge in the longitudinal direction X of the pad-side fastening structure 8 or is positioned outward in the longitudinal direction X beyond the inner edge. With this configuration, in combination with the characteristic configuration of the present invention described above, the desired effects of the present invention are more reliably achieved. The "stretch start position of the leg cuff 65" refers to one end in the vertical direction X of a stretchable region (arrangement region of the upright portion 62) in which the leg cuff forming elastic member 66 constituting the leg cuff 65 is arranged so as to be stretchable in the vertical direction X. The stretchable region typically extends in the same direction over at least the entire length of the vertical direction X of the crotch portion M, and further extends to each of the abdominal portion F and the dorsal portion R. The "inner edge in the vertical direction X of the pad side fastening structure 8" refers to the inner edge in the vertical direction X of the one (the fastening element 8B in this embodiment) located at the innermost position in the vertical direction X among the multiple pad side fastening structures 8 intermittently arranged in the vertical direction X in the end region of the absorbent pad 1 in the vertical direction X. The "inner edge" here refers to the one located on the inner side in the vertical direction X (the side closer to the absorbent body 5) among a pair of vertical direction X edges of the pad side fastening structure 8 extending in the lateral direction Y. The pair of edges in the longitudinal direction X of the pad-side fastening structure 8 includes the inner edge and an outer edge positioned opposite to the inner edge.

[0038] 2 and 3, the present embodiment includes stretchable first leakage preventing cuffs 6 (lateral leakage preventing cuffs) extending along the longitudinal direction X at a position inward of the leg cuffs 65 in the lateral direction Y, and it is preferable that the stretch start position of the first leakage preventing cuffs 6 on at least one of the ventral side (ventral portion F) and the dorsal side (dorsal portion R) coincides with the inner edge of the pad-side fastening structure 8 in the longitudinal direction X, or is positioned beyond the inner edge and outward in the longitudinal direction X. This configuration, together with the characteristic configuration of the present invention described above, makes it possible to more reliably achieve the desired effects of the present invention. The "stretch start position of the first leakage preventing cuff 6" refers to one end in the vertical direction X of a stretchable region (region where the upright portion 62 is disposed) in which the first elastic member 61 constituting the first leakage preventing cuff 6 is arranged so as to be stretchable in the vertical direction X. The stretchable region typically extends in the same direction in the vertical direction X over at least the entire length of the crotch portion M, and further extends into each of the abdominal portion F and the dorsal portion R.

[0039] Figures 6 to 11 show the main part (pad-side fastening structure and its vicinity) of another embodiment of the absorbent pad of the present invention. The absorbent pads in Figures 6 to 8 are those in which the method A is adopted, and the absorbent pads in Figures 9 to 11 are those in which the method B is adopted. 6 to 11, configurations different from the absorbent pad 1 will be mainly described, and configurations similar to those of the absorbent pad 1 will be given the same reference numerals and will not be described. For configurations not specifically described in the absorbent pads of Figs. 6 to 11, the description of the absorbent pad 1 will be applied as appropriate. Furthermore, for the absorbent pads of Figs. 6 to 11, the ventral part F will be described, but the description of the ventral part F will also be applied as appropriate to the dorsal part R, unless otherwise specified.

[0040] 6, the pad-side fastening structure 8 includes a plurality (two) fastening elements 8A and 8B, similarly to the absorbent pad 1, and the fastening element 8A located on the outer side of the vertical direction X has a longer length (width) in the vertical direction X than the fastening element 8B located on the inner side of the vertical direction X, and a relationship of "width W1 of fastening element 8A > width W2 of fastening element 8B" is established. In the absorbent pad 1A, the fastening elements 8A and 8B both have the same length in the horizontal direction Y and the same configuration of the fastening structure (configuration of the male member of the mechanical hook-and-loop fastener, arrangement number per unit area of ​​the engaging members constituting the male member, etc.), and therefore have the same fastening force per unit area. Therefore, since the magnitude relationship regarding the width is established, in the pad-side fastening structure 8, the part located on the outer side of the vertical direction X (fastening element 8A) has a stronger fastening force to the holder than the part located on the inner side of the vertical direction X (fastening element 8B).

[0041] The absorbent pad 1B shown in FIG. 7 is different from the absorbent pad 1A in that the pad-side fastening structure 8 includes four fastening elements 8A, 8B, in that the number of fastening elements constituting the pad-side fastening structure 8 is two. The four fastening elements 8A, 8B are composed of one wide fastening element 8A located on the outer side in the vertical direction X and having a relatively long length (width) in the vertical direction X, and three narrow fastening elements 8B located on the innermost side in the vertical direction X and having a relatively short width. The widths of the three fastening elements 8B are the same. That is, in the absorbent pad 1B, the relationship "width W1 of the fastening element 8A>width W2 of the fastening element 8B" is established. Therefore, in the pad-side fastening structure 8 of the absorbent pad 1B, the part located on the outer side in the vertical direction X (fastening element 8A) has a stronger fastening force to the holder than the part located on the inner side in the vertical direction X (fastening element 8B).

[0042] The absorbent pad 1C shown in FIG. 8 differs from the absorbent pad 1A in which the fastening elements 8A, 8B are each fastening elements extending in a single lateral direction Y, in that the fastening elements 8A, 8B each include a plurality of fastening elements 80 arranged intermittently in the lateral direction Y.

[0043] In the above-mentioned absorbent pads 1A to 1C, from the viewpoint of ensuring the effect resulting from the difference in partial fastening force of the above-mentioned pad-side fastening structure 8, the ratio of the width W1 of the portion located on the outer side of the longitudinal direction X to the width W2 of the portion located on the inner side of the longitudinal direction X, expressed as width W1 / width W2, is preferably 1.1 or more, more preferably 1.2 or more, and is preferably 5 or less, more preferably 6 or less, assuming that width W1>width W2. Width W1 (see Figs. 6 to 8) is presumed to be longer than width W2, and is preferably 5 mm or more, more preferably 10 mm or more, and is preferably 50 mm or less, more preferably 40 mm or less. Width W2 (see Figs. 6 to 8) is presumed to be shorter than width W1, and is preferably 2 mm or more, more preferably 5 mm or more, and is preferably 30 mm or less, more preferably 25 mm or less. The present invention includes a configuration in which the widths W1, W2 are not constant over the entire lateral length of the fastening element (pad side fastening structure). In such a configuration, it is preferable that the minimum widths W1, W2 are each within the above-mentioned ranges.

[0044] The absorbent pad 1D shown in Fig. 9 is different from the absorbent pad 1A in that the multiple (two) fastening elements 8A, 8B constituting the pad-side fastening structure 8 have the same shape and size, and the widths (lengths in the vertical direction X) of the fastening elements 8A, 8B are different from each other. In the absorbent pad 1D, the portion (fastening element 8A) located on the outer side of the vertical direction X in the pad-side fastening structure 8 is not subjected to the compression process, or the ratio of the area of ​​the compressed portion (compressed portion) 81 to the total area of ​​the portion (hereinafter also referred to as "compressed portion area ratio") is lower than the portion (fastening element 8B) located on the inner side of the vertical direction X in the pad-side fastening structure 8. In the embodiment shown in Fig. 9, the compressed portion 81 is formed in the fastening element 8B, whereas the compressed portion 81 is not formed in the fastening element 8A, and the compressed portion area ratio of the fastening element 8A is zero. In the fastening element 8B, two compressed portions 81 having a wavy shape in a plan view and arranged at intervals in the vertical direction X extend over the entire length in the horizontal direction Y of the fastening element 8B. The compressed portion 81 does not have a fastening force to the holder because the fastening structure such as the male member of the mechanical hook-and-loop fastener is destroyed by the compression process. Therefore, the fastening element 8A having a relatively low compressed portion area ratio has a stronger fastening force to the holder than the fastening element 8B having a relatively high compressed portion area ratio. The area ratio of the compressed portion in the fastening element 8B (the portion located on the inner side in the longitudinal direction X in the pad side fastening structure 8) is preferably 5% or more, more preferably 10% or more, and is preferably 50% or less, more preferably 30% or less, from the viewpoint of ensuring the minimum required fastening force while more reliably achieving the effect resulting from the partial fastening force difference of the pad side fastening structure 8 described above. The compression process for forming the compressed portion 81 may be any process capable of destroying the fastening structure such as the male member, and examples thereof include known embossing processes such as embossing with or without the application of heat, ultrasonic embossing, etc.

[0045] The absorbent pad 1E shown in Fig. 10 differs from the absorbent pad 1D in that the difference between the multiple fastening elements 8A, 8B constituting the pad-side fastening structure 8 is the number of engaging members 83 constituting the male member of the mechanical hook-and-loop fastener arranged per unit area. The absorbent pad 1E does not have the compressed portions 81 formed in the pad-side fastening structure 8. In fastening elements 8A and 8B, which are male members of the mechanical hook-and-loop fastener, the male members include a base material 82 and a plurality of engaging members 83 arranged on one surface of the base material 82, as shown in an enlarged view in Fig. 10, and in the absorbent pad 1E, the pattern of the engaging members 83 is different between a portion (fastening element 8A) located on the outer side of the vertical direction X in the pad side fastening structure 8 and a portion (fastening element 8B) located on the inner side of the vertical direction X in the pad side fastening structure 8, and specifically, the number of engaging members 83 arranged per unit area is greater in the fastening element 8A than in the fastening element 8B. Therefore, in the pad side fastening structure 8 of the absorbent pad 1E, the fastening element 8A has a stronger fastening force to the holder than the fastening element 8B. As the base material 82 and the engaging member 83, those employed in the male members of known mechanical hook-and-loop fasteners can be used without any particular limitation. The "pattern of the engaging members 83" is determined by the "shape of the engaging members 83" and the "number of the engaging members 83 arranged per unit area". Therefore, as a method for partially varying the pattern of the engaging members 83 in the pad side fastening structure 8, instead of the latter, the former method, i.e., a method of varying the shape of the engaging members 83, may be adopted, or a method of making both different may be adopted.

[0046] 11 differs from absorbent pad 1E in that pad-side fastening structure 8 has a single continuous shape, and is composed of a plurality of fastening elements 8A, 8B arranged at intervals in the longitudinal direction X. That is, in absorbent pad 1F, fastening elements 8A arranged in a relatively large number per unit area of ​​engaging members 83 and fastening elements 8B arranged in a relatively small number are integrated to form a single pad-side fastening structure 8 in the end region in the longitudinal direction X of absorbent pad 1F.

[0047] In the absorbent pads 1D to 1F described above, the widths (lengths in the vertical direction X) of the multiple fastening elements 8A, 8B constituting the pad-side fastening structure 8 are the same as each other. However, the widths of the multiple fastening elements constituting the pad-side fastening structure 8 may be different from each other, provided that the fastening force to the holder has the following relationship: "portion located on the outer side in the vertical direction X (fastening element 8A) > portion located on the inner side in the vertical direction X (fastening element 8B)".

[0048] The present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the spirit of the present invention. For example, the absorbent pad of the present invention may be provided with a disposal tape and an indicator for notifying the wearer of excretion. The disposal tape is for maintaining the state of the absorbent pad rolled up when the used absorbent pad is rolled up small and discarded. The disposal tape is typically provided on the non-skin-facing surface (outer surface) of the absorbent pad, and when used, is arranged so as to straddle one end of the absorbent pad rolled up vertically with the skin-facing surface (inner surface) facing inward, in the same direction, thereby maintaining the rolled state of the absorbent pad. The indicator is used for the purpose of notifying the time to replace the absorbent pad, and is typically made to change color visually by contact with urine, and the color change of the indicator is made visible from the outside of the absorbent pad. As the disposal tape and the indicator, those conventionally used in this type of absorbent article can be used without any particular restrictions.

[0049] In the above embodiment, the pad side fastening structure 8 was provided on the skin-facing surface (inner surface) of the absorbent pad 1, but in the present invention, it may be provided on the non-skin-facing surface (outer surface) of the absorbent pad 1, in which case, for example, the pad side fastening structure 8 can be fixed to the non-skin-facing surface of the back sheet 4.

[0050] In the above embodiment, the pad side fastening structure 8 is a male member of the mechanical hook-and-loop fastener, and the holder side fastening structure 14 is a female member of the mechanical hook-and-loop fastener, but in the present invention, the pad side fastening structure 8 may be a female member of the mechanical hook-and-loop fastener, and the holder side fastening structure 14 may be a male member of the mechanical hook-and-loop fastener.
