Description

Technical Field

[0001] The present disclosure relates to a wearing article. Background Art

[0002] Conventionally, there is known a cloth underwear or other wearing article that is used by attaching a disposable absorbent pad inside. For example, Patent Document 1 discloses a structure in which an absorbent pad (absorbent insert) is attached to the inner surface (skin side) of a wearing article (outer cover) worn around the lower body of the wearer by means of Velcro tapes provided at both ends of the outer cover in the longitudinal direction.

[0003] Prior art literature

[0004] Patent Literature

[0005] Patent Document 1: Japanese Patent Application No. 2013-534457 Summary of the invention

[0006] Problem that the invention aims to solve

[0007] In the method disclosed in Patent Document 1, where only the ends of the absorbent pad in the longitudinal direction are fixed (connected) to the wearing article, there is a concern that the absorbent pad will be caught in the crotch of the wearer when worn, and the absorbent core disposed inside the absorbent pad will be twisted, resulting in a concern that urine leakage or the like will easily occur.

[0008] On the other hand, in order to avoid the occurrence of the above-mentioned distortion of the absorbent core, when the back side (the side opposite to the inner side of the wearing article) of the absorbent pad is bonded (joined) to the inner side of the wearing article as a whole using an adhesive tape (double-sided tape, etc.), it is difficult to attach the back side of the absorbent pad to the wearing article as a whole in a manner that does not cause wrinkles. That is, in the case of using a wearing article that is stretchable in the longitudinal direction, if the absorbent pad is attached in a state where the wearing article is contracted in the longitudinal direction (in a state where it is not fully stretched), there is a concern that the bonding surface between the wearing article and the absorbent pad will be offset or wrinkled. Furthermore, if the bonding area between the wearing article and the absorbent pad is large, the softness and wearing feel of the wearing article will be impaired, and a large force will be required to remove (peel off) the absorbent pad from the wearing article.

[0009] Therefore, an object of one aspect of the present disclosure is to provide a wearing article used together with an absorbent pad, in which the absorbent pad can be easily attached and detached while suppressing the occurrence of distortion of the absorbent pad when worn.

[0010] Solutions for solving problems

[0011] The wearing article of one aspect of the present disclosure is a reusable cloth underwear that is worn around the lower body of the wearer through an absorbent pad, wherein the wearing article comprises: a main body portion, which has a ventral portion located on the ventral side of the wearer when the wearing article is worn by the wearer, a dorsal portion located on the dorsal side of the wearer when the wearing article is worn, and a crotch portion located between the ventral portion and the dorsal portion; and a plurality of coupling portions, which are provided on the inner surface of the main body portion that is opposite to the absorbent pad when worn and are configured to be coupled to the absorbent pad, the plurality of coupling portions having a ventral coupling portion provided on the ventral portion, a dorsal coupling portion provided on the dorsal portion, and a crotch coupling portion provided on the crotch portion, and the ventral coupling portion, the crotch coupling portion, and the dorsal coupling portion are arranged separately from each other in the direction in which the ventral portion, the crotch portion, and the dorsal portion are arranged, i.e., in the length direction.

[0012] Effects of the Invention

[0013] According to the present disclosure, it is possible to provide a wearing article that is used together with an absorbent pad and that allows easy attachment and detachment of the absorbent pad while suppressing the occurrence of distortion of the absorbent pad when worn.

[0023] At least the following aspects 1 to 20 are clarified from the description of this specification and the drawings.

[0024] (Method 1)

[0025] A wearing article is a reusable cloth underwear which is worn around the lower part of the torso of a wearer through an absorbent pad, wherein:

[0026] The article of clothing has:

[0027] a main body having a ventral portion located on the ventral side of the wearer when the article is worn by the wearer, a dorsal portion located on the dorsal side of the wearer in the worn state, and a crotch portion located between the ventral portion and the dorsal portion; and

[0028] a plurality of coupling parts, which are provided on the inner surface of the main body portion facing the absorbent pad in the wearing state and are configured to be coupled to the absorbent pad,

[0029] The plurality of joints include a ventral joint provided at the ventral portion, a dorsal joint provided at the dorsal portion, and a crotch joint provided at the crotch portion.

[0030] The ventral joint portion, the crotch joint portion, and the dorsal joint portion are arranged in a longitudinal direction so as to be separated from each other.

[0031] In method 1, a joint is provided not only at both ends in the length direction (ventral part and dorsal part), but also at the crotch part (crotch joint). Thus, when the absorbent pad is mounted on the wearing article (hereinafter referred to as the "mounted state"), the absorbent pad can be prevented from being misaligned with respect to the wearing article, and the absorbent pad can be prevented from being caught in the crotch of the wearer. That is, if the crotch joint is not provided and the absorbent pad can be separated from the wearing article at the crotch of the wearer, there is a concern that the absorbent pad will only be caught in the crotch of the wearer due to the movement of the wearer, thereby causing distortion in the absorbent core. By coupling the absorbent pad to the wearing article at the crotch joint, the above-mentioned situation can be avoided.

[0032] In addition, in mode 1, the ventral joint, the crotch joint, and the dorsal joint are arranged separately from each other in the length direction. This can achieve the following effects. Wearing articles as cloth underwear usually have a force to shrink in the length direction. Therefore, assuming that a joint (a portion that is joined to a wearing article) is provided on the entire back side of the absorbent pad (for example, the entire back side of the absorbent pad is bonded to the wearing article, etc.), it is difficult to install the absorbent pad on the wearing article in a state that is naturally contracted in the length direction (hereinafter referred to as the "contracted state"). That is, in order to properly install the absorbent pad on the wearing article, it is necessary to install the absorbent pad in a state that stretches the wearing article in the length direction, but at this time there is a concern that the wearing article cannot be fully and thoroughly stretched, and wrinkles appear on the bonding surface (adhesive surface, etc.) between the absorbent pad and the wearing article. In addition, since the area of ​​the bonding surface is large, it is not easy to remove the absorbent pad from the wearing article. In contrast, in the absorbent pad described above, since the respective coupling parts at the two end portions (ventral portion and dorsal portion) and the crotch portion arranged in the length direction are arranged separately from each other, the absorbent pad can be easily attached to the wearing article in the contracted state. In addition, compared with the case where the entire back side of the absorbent pad is coupled to the wearing article as described above, the area of ​​the coupling surface can be reduced, so the absorbent pad can be easily removed from the wearing article. Based on the above, by using a wearing article having a ventral coupling part, a dorsal coupling part, and a crotch coupling part separated from each other in the length direction, the absorbent pad can be easily attached and detached while suppressing the occurrence of distortion of the absorbent pad in the wearing state.

[0033] (Method 2)

[0034] The wearing article according to aspect 1, wherein

[0035] The abdominal joint portion is disposed in the longitudinal direction between a front end portion of the abdominal portion which is an end portion on the opposite side of the crotch portion and a leg opening portion of the abdominal portion.

[0036] According to the second aspect, the ventral joint portion can be arranged at a position sufficiently close to the ventral end portion (front end portion) (i.e., a position close to the position where the ventral end portion of the absorbent pad is arranged). As a result, the ventral end portion of the absorbent pad can be appropriately positioned and fixed by the ventral joint portion.

[0037] (Method 3)

[0038] The wearing article according to aspect 1 or aspect 2, wherein:

[0039] The abdominal portion has an abdominal elastic member provided along the front end portion and contracted in a width direction orthogonal to the longitudinal direction so as to tighten the waist of the wearer in the wearing state.

[0040] The abdominal joint portion is disposed closer to the crotch portion than the abdominal elastic member in the longitudinal direction.

[0041] According to method 3, it is possible to prevent the contraction of the ventral elastic member from being hindered by the ventral joint portion, and to prevent the ventral joint portion from contracting in the width direction due to the influence of the ventral elastic member (as a result, it is difficult to connect the absorbent pad to the ventral joint portion).

[0042] (Method 4)

[0043] The wearing article according to any one of aspects 1 to 3, wherein:

[0044] The length of the ventral joint portion in the width direction orthogonal to the longitudinal direction is shorter than the width of the narrowest portion of the main body portion.

[0045] According to the fourth embodiment, the wasted portion of the ventral joint portion that is not joined to the absorbent pad can be reduced. In addition, when the ventral joint portion is formed of a harder material than the fabric of the main body portion, there is a concern that the larger the area of ​​the ventral joint portion, the greater the discomfort felt by the wearer when wearing the garment. By setting the width of the ventral joint portion as in the fourth embodiment, the discomfort described above can be suppressed.

[0046] (Method 5)

[0047] The wearing article according to any one of aspects 1 to 4, wherein:

[0048] The back joint portion is disposed in the longitudinal direction between a rear end portion of the back portion that is an end portion on the opposite side of the crotch portion and a leg opening portion of the back portion.

[0049] According to aspect 5, the back side joint portion can be arranged at a position sufficiently close to the back side end portion (rear end portion) (i.e., a position close to the position where the back side end portion of the absorbent pad is arranged). As a result, the back side joint portion can be used to appropriately position and fix the back side end portion of the absorbent pad.

[0050] (Method 6)

[0051] The wearing article according to any one of aspects 1 to 5, wherein:

[0052] The back portion has a back elastic member, the back elastic member being provided along the rear end portion and contracting in a width direction orthogonal to the longitudinal direction so as to tighten the waist of the wearer in the wearing state.

[0053] The back-side connecting portion is disposed closer to the crotch portion than the back-side elastic member in the longitudinal direction.

[0054] According to method 6, it is possible to prevent the back side joint from obstructing the contraction of the back elastic member, and to prevent the back side joint from contracting in the width direction due to the influence of the back elastic member (as a result, it is difficult to connect the absorbent pad to the back side joint).

[0055] (Method 7)

[0056] The wearing article according to any one of aspects 1 to 6, wherein:

[0057] The length of the back-side connecting portion in the width direction perpendicular to the longitudinal direction is shorter than the width of the narrowest portion of the main body portion.

[0058] According to the seventh embodiment, the wasted portion of the back-side joint portion that is not joined to the absorbent pad can be reduced. In addition, when the back-side joint portion is formed of a harder material than the fabric of the main body portion, there is a concern that the larger the area of ​​the back-side joint portion, the greater the discomfort felt by the wearer when wearing the garment. By setting the width of the back-side joint portion as in the seventh embodiment, the discomfort described above can be suppressed.

[0059] (Method 8)

[0060] The wearing article according to any one of aspects 1 to 7, wherein:

[0061] The crotch joint portion extends along a width direction orthogonal to the length direction.

[0062] The length of the crotch joint portion in the width direction is longer than the length of the crotch joint portion in the length direction.

[0063] According to aspect 8, the crotch joint portion extending in the width direction can effectively suppress movement (distortion, etc.) of the absorbent pad (the portion joined to the crotch joint portion) in the width direction.

[0064] (Method 9)

[0065] The wearing article according to aspect 8, wherein

[0066] The length of the crotch joint portion in the width direction orthogonal to the longitudinal direction is shorter than the length of the abdominal joint portion in the width direction and the length of the dorsal joint portion in the width direction.

[0067] According to the ninth aspect, the width of the ventral joint part and the dorsal joint part arranged at both ends in the longitudinal direction is made relatively long, so that the wearing article and the absorbent pad can be firmly joined. On the other hand, the width of the lower crotch joint part arranged in the crotch part which has a greater impact on the wearer's wearing feeling is made relatively short, so that the discomfort in the crotch part felt by the wearer when wearing can be reduced.

[0068] (Method 10)

[0069] The wearing article according to any one of aspects 1 to 9, wherein:

[0070] The length of the crotch joint portion in the width direction perpendicular to the longitudinal direction is shorter than the width of the narrowest portion of the main body portion.

[0071] According to the embodiment 10, the wasted portion of the crotch joint portion that is not joined to the absorbent pad can be reduced. In addition, when the crotch joint portion is formed of a raw material harder than the fabric of the main body, there is a concern that the larger the area of ​​the crotch joint portion, the greater the discomfort felt by the wearer when wearing the garment. By setting the width of the crotch joint portion as in the embodiment 10, the discomfort described above can be suppressed.

[0072] (Method 11)

[0073] The wearing article according to any one of aspects 1 to 10, wherein:

[0074] The distance from the first end of the crotch joint in the width direction orthogonal to the length direction to the second end of the crotch joint on the opposite side of the first end in the width direction is greater than 1 / 3 of the width of the narrowest part of the main body.

[0075] According to aspect 11, by ensuring that the width of the crotch joint portion is greater than a certain level, it is possible to effectively suppress movement (distortion, etc.) of the absorbent pad (the portion joined to the crotch joint portion) in the width direction.

[0076] (Method 12)

[0077] The wearing article according to any one of aspects 1 to 11, wherein:

[0078] The crotch joint portion includes a first crotch joint portion and a second crotch joint portion.

[0079] The first crotch joint portion is disposed closer to the abdominal portion than the second crotch joint portion in the longitudinal direction.

[0080] According to method 12, by making the crotch joint part consist of multiple joint parts (the first crotch joint part and the second crotch joint part), it is possible to more effectively prevent the absorbent pad from being sandwiched between the wearer's crotch when worn, and further more effectively prevent the occurrence of twisting of the absorbent core.

[0081] (Method 13)

[0082] The wearing article according to aspect 12, wherein

[0083] The first crotch joint portion is arranged at a position closer to the abdominal portion than the central position of the main body portion in the longitudinal direction.

[0084] The second crotch joint is arranged at a position closer to the back portion than the central position.

[0085] According to the thirteenth aspect, by providing the first lower crotch joint part and the second lower crotch joint part in a manner corresponding to the urination opening and the defecation opening, respectively, the occurrence of distortion of the absorbent core can be suppressed at a position close to the urination opening and the defecation opening. As a result, the absorption leakage of excrement can be appropriately suppressed.

[0086] (Method 14)

[0087] The wearing article according to aspect 13, wherein

[0088] The first crotch joint portion and the second crotch joint portion are arranged asymmetrically with respect to the central position.

[0089] (Method 15)

[0094] In the longitudinal direction, a distance from the ventral joint portion to the first crotch joint portion is shorter than a distance from the second crotch joint portion to the dorsal joint portion.

[0095] According to the 14th, 15th and 16th aspects, the first crotch joint part can be brought close to the position corresponding to the urination opening, and the second crotch joint part can be brought close to the position corresponding to the defecation opening. As a result, the occurrence of distortion of the absorbent core can be effectively suppressed at a position closer to the urination opening and the defecation opening, and the absorption leakage of excrement can be further effectively suppressed.

[0096] (Method 17)

[0097] The wearing article according to any one of aspects 1 to 16, wherein:

[0098] The stiffness of the first part is lower than the stiffness of the second part and the stiffness of the third part.

[0110] The total length of the first non-bonded area between the ventral joint and the crotch joint and the second non-bonded area between the dorsal joint and the crotch joint in the length direction is more than half of the distance between the ventral joint and the dorsal joint.

[0111] According to the embodiment 20, the size of the first non-bonding area (size in the length direction) and the size of the second non-bonding area (size in the length direction) can be sufficiently ensured between the ventral bonding part and the dorsal bonding part. As a result, when the absorbent pad is attached to or detached from the wearing article, the force required to stretch the wearing article in the length direction can be reduced. As a result, the absorbent pad can be attached to or detached from the wearing article more easily.

[0112] [Implementation Method]

[0113] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same or corresponding elements, and repeated descriptions are omitted.

[0114] [First embodiment]

[0115] Reference Figure 1 and Figure 2 The structure of the wearing article 1 according to the first embodiment will be described. Figure 1 This is a plan view of the wearing article 1 as viewed from the skin side. Figure 2 This is a plan view of the wearing article 1 as viewed from the non-skin side. Figure 1 and Figure 2 The state in which the wearing article 1 is stretched to a state where wrinkles are not formed (hereinafter referred to as "stretched state") is shown. In the present embodiment, the wearing article 1 is a belt-type cloth underwear.

[0116] In the present embodiment, the "wearer" is a person wearing the wearing article 1 with the absorbent pad 2 attached. The "skin side" is the side facing the wearer's skin when the absorbent pad 2 is worn on the wearer together with the wearing article 1 (hereinafter referred to as the "wearing state"). The "non-skin side" is the side facing the opposite side to the wearer's skin in the wearing state.

[0117] Next, the stretched state of the wearing article 1 (refer to Figure 1 and Figure 2 ) is represented as "length direction L", the short side direction of the absorbent pad 2 perpendicular to the length direction L is represented as "width direction W", and the direction perpendicular to the length direction L and the width direction W is represented as "thickness direction T". In addition, a straight line passing through the central part of the wearing article 1 in the length direction L and parallel to the width direction W is represented as "center line CL". The length direction L is a direction extending from the front side (abdomen) of the wearer's body to the back side (dorsum) of the body when worn. The width direction W is a direction consistent with the left-right direction of the wearer when worn. The thickness direction T is the direction in which the raw materials constituting the wearing article 1 (the main body 10, the connecting part 30, etc. described later) are stacked.

[0118] The wearing article 1 is a recyclable cloth underwear which is worn around the lower part of the torso of the wearer via an absorbent pad 2. The absorbent pad 2 is attached to the wearing article 1 and is arranged between the wearing article 1 and the wearer.

[0119] The wearing article 1 has a main body portion 10. Figure 1 and Figure 2 As shown, the main body 10 has an inner surface 10a opposite to the back side (back sheet 22 described later) of the absorbent pad 2 in the wearing state and an outer surface 10b on the opposite side of the inner surface 10a. The main body 10 is divided into an abdominal part 101 located on the abdominal side of the wearer in the wearing state, a dorsal part 102 located on the dorsal side of the wearer in the wearing state, and a crotch part 103 located between the abdominal part 101 and the dorsal part 102. The abdominal part 101, the crotch part 103, and the dorsal part 102 are arranged along the length direction L from the abdominal side (front) to the dorsal side (back) of the wearer. As an example, when the main body 10 is divided into four equal parts in the length direction L, a region located at the most abdominal position corresponds to the abdominal part 101, a region located at the most dorsal position corresponds to the dorsal part 102, and two regions located between the abdominal part 101 and the dorsal part 102 (i.e., the longitudinal center of the main body 10) correspond to the crotch part 103.

[0120] The inner surface 10a of the dorsal part 102 is provided with fixing parts 11 at both ends in the width direction W. The fixing parts 11 are constituted by, for example, hooks of nylon Velcro. In addition, the outer surface 10b of the ventral part 101 is provided with fixing parts 12 corresponding to the fixing parts 11 at both ends in the width direction W. The fixing parts 12 are constituted by, for example, loops of nylon Velcro. Figure 6 As shown in FIG. 1 , in the wearing state, each fixing part 11 is combined with each fixing part 12. Thus, the entire area of ​​the crotch portion 103 and the part of the ventral portion 101 near the crotch portion 103 and the part of the dorsal portion 102 near the crotch portion 103 are combined. Figure 1 The side edge portion in the width direction W of the range R) constitutes the leg opening portion 13.

[0121] The leg opening 13 is a portion that forms an opening for the wearer's legs to pass through when the leg opening 13 is worn. An elastic member 14 that contracts along the leg opening 13 is provided along the leg opening 13. In addition, an elastic member 15 (abdomen elastic member) that contracts along the width direction W in a manner that tightens the wearer's waist when worn is provided along the front end 101a of the abdomen 101. An elastic member 16 (back elastic member) that contracts along the width direction W in a manner that tightens the wearer's waist when worn is provided along the rear end 102a of the back 102. The elastic members 14, 15, 16 are, for example, elastic bands, stretchable sheets, and the like.

[0122] When viewed from the thickness direction T, the main body 10 is formed in a gourd shape (or an hourglass shape), and a narrowest portion 17 where the width (length in the width direction W) of the main body 10 is the smallest is formed in the crotch portion 103 .

[0123] The inner surface 10a is provided with a plurality of coupling parts 30 configured to be coupled to the absorbent pad 2. In addition, "coupling" refers to a state where the absorbent pad 2 is fixed to a detachable degree, including various means such as snapping and bonding. The coupling part 30 can be composed of, for example, an area including a plurality of pins (hook structure) having claws at the top end. The plurality of coupling parts 30 include a ventral coupling part 31, a dorsal coupling part 32 and a crotch coupling part 33. The ventral coupling part 31 is provided on the ventral part 101 of the inner surface 10a. The dorsal coupling part 32 is provided on the dorsal part 102 of the inner surface 10a. The crotch coupling part 33 is provided on the crotch part 103 of the inner surface 10a. In the length direction L, the ventral coupling part 31, the crotch coupling part 33 and the dorsal coupling part 32 are arranged separately from each other.

[0124] The plurality of joints 30 have a structure in which the joint at the crotch joint 33 is weaker than the joint at the ventral joint 31 and the joint at the back joint 32 (hereinafter referred to as a "specific joint structure"). That is, when the absorbent pad 2 is joined to the wearing article 1 via the plurality of joints 30, the force required to release the joint between the absorbent pad 2 and the wearing article 1 at the crotch joint 33 is smaller than the force required to release the joint between the absorbent pad 2 and the wearing article 1 at the ventral joint 31 and the force required to release the joint between the absorbent pad 2 and the wearing article 1 at the back joint 32. A specific structural example of the joint 30 will be described later.

[0125] As an example, when viewed from the thickness direction T, the ventral joint 31 and the dorsal joint 32 have the same rectangular shape. The ventral joint 31 and the dorsal joint 32 are formed into a rectangular shape extending in the width direction W (i.e., a rectangular shape whose length in the width direction W is longer than the length in the length direction L). When viewed from the thickness direction T, the crotch joint 33 (in this embodiment, each of the first crotch joint 331 and the second crotch joint 332 described later) has a rectangular shape smaller than the ventral joint 31 and the dorsal joint 32. Similar to the ventral joint 31 and the dorsal joint 32, the crotch joint 33 is also formed into a rectangular shape extending in the width direction W. As an example, the length of the crotch joint 33 in the length direction L is consistent with the length of the ventral joint 31 and the dorsal joint 32 in the length direction L. On the other hand, the length of the crotch joint 33 in the width direction W is shorter than the lengths of the ventral joint 31 and the dorsal joint 32 in the width direction W. The center positions of the ventral joint 31, the dorsal joint 32 and the crotch joint 33 in the width direction W coincide with the center position of the main body 10 in the width direction W.

[0126] Next, refer to Figure 3 to Figure 6 The absorbent pad 2 attached to the wearing article 1 will be described. Figure 3 This is a plan view of the absorbent pad 2 as viewed from the skin side. Figure 4 This is a plan view of the absorbent pad 2 as viewed from the non-skin side. Figure 5 It is a top view of the wearing article 1 with the absorbent pad 2 attached. Figure 6 It is a perspective view of the wearing article 1 to which the absorbent pad 2 is attached.

[0127] The absorbent pad 2 has a main body 20. Figure 3 and Figure 4 As shown, the main body 20 has a rectangular shape when viewed from the thickness direction T in the stretched state. The main body 20 includes a surface sheet 21, a back sheet 22, and an absorbent body 23. The components such as the surface sheet 21, the back sheet 22, and the absorbent body 23 can be bonded to each other using a known material such as an adhesive.

[0128] The top sheet 21 is a liquid-permeable sheet disposed on the skin side of the wearer and facing the skin of the wearer when worn. The top sheet 21 can be formed of, for example, a liquid-permeable nonwoven fabric or woven fabric, a synthetic resin film having liquid-permeable holes, or a composite sheet thereof.

[0129] The back sheet 22 is a liquid-impermeable sheet disposed on the non-skin side of the wearer and facing the wearing article 1 when worn. The back sheet 22 can be formed of, for example, a liquid-impermeable nonwoven fabric, a synthetic resin film, or a composite sheet thereof.

[0130] The absorbent body 23 is disposed between the surface sheet 21 and the back sheet 22. The absorbent body 23 includes an absorbent core 23a and a core wrap (not shown) covering the absorbent core 23a. The absorbent core 23a is a member for absorbing the excrement of the wearer, and has liquid absorbency and liquid retention. The absorbent core 23a is, for example, a laminate of an absorbent material containing pulverized pulp or a superabsorbent polymer (SAP), or a mixture thereof. The core wrap is, for example, tissue paper or a nonwoven fabric sheet.

[0131] like Figure 3 As shown, in the present embodiment, as an example, when viewed from the thickness direction T, the absorbent core 23a is formed into a gourd shape (or an hourglass shape), and has a shape in which the central portion of the absorbent core 23a in the longitudinal direction L is narrowed. That is, the width (length in the width direction W) of the absorbent core 23a is the largest at the portion including both ends of the ventral side and both ends of the dorsal side, and is the smallest at the portion including the approximately central portion in the longitudinal direction L of the absorbent core 23a.

[0132] A pair of leg gathers 24 are provided on both sides of the body 20 in the width direction W. The leg gathers 24 extend along the length direction L over substantially the entire area of ​​the body 20 in the length direction L. A fixing area B ( 24 ) is provided at both ends of the leg gathers 24 in the length direction L where the leg gathers 24 and the top sheet 21 are fixed to each other. Figure 3 The leg side gathers 24 and the surface sheet 21 are fixed (bonded) to each other in the fixing region B, for example, by sticking with an adhesive or the like, ultrasonic bonding, or heat fusion bonding with an embossing roller.

[0133] The leg side gathers 24 are configured to be able to stand up by contracting along the length direction L. More specifically, the leg side gathers 24 have an elastic member 25 extending along the length direction L between a pair of fixed areas B at both end portions provided in the length direction L. As an example, the elastic member 25 is composed of one or more (three in the present embodiment) elastic threads. The leg side gathers 24 can stand up by contracting the elastic member 25 along the length direction L. In the worn state, the elastic member 25 contracts and the leg side gathers 24 are in an upright state, thereby suppressing the leakage of excrement to the outside of the main body 20 (side leakage). That is, by the leg side gathers 24 being in an upright state, a leak-proof cuff is formed to prevent excrement from leaking to the outside along the surface of the surface sheet 21.

[0134] Figure 3 The leg side gathers 24 are folded inwardly in the width direction W. Figure 3In the embodiment, the top 24a of the leg gathers 24 is located inside the outer end of the body 20 in the width direction W. In the present embodiment, as an example, the back sheet 22 is integrated with the leg gathers 24. Thus, the outer end of the body 20 in the width direction W coincides with the standing fulcrum 24b of the leg gathers 24. The standing fulcrum 24b is the root portion (the folding start point) of the standing portion of the leg gathers 24, and extends in the length direction L.

[0135] like Figure 5 As shown in FIG. 1 , the wearing article 1 has a shape larger than the absorbent pad 2. That is, the length of the wearing article 1 in the longitudinal direction L is longer than the length of the absorbent pad 2 in the longitudinal direction L. In addition, the width (length in the width direction W) of the absorbent pad 2 is larger than the width Lmin (see FIG. 1 ) of the narrowest portion 17 of the wearing article 1. Figure 1 In this embodiment, the absorbent pad 2 is attached to the approximate center of the wearing article 1 in the length direction L and the width direction W. More specifically, Figure 4 As shown, a plurality of corresponding regions 40 corresponding to the plurality of joints 30 provided on the inner surface 10a of the wearing article 1 are provided on the surface 22a of the back sheet 22 of the absorbent pad 2. Each corresponding region 40 is a region having a surface that can be joined to each joint 30. The plurality of corresponding regions 40 include a corresponding region 41 corresponding to the ventral joint 31, a corresponding region 42 corresponding to the dorsal joint 32, and a corresponding region 43 corresponding to the crotch joint 33 (in this embodiment, a corresponding region 431 corresponding to the first crotch joint 331 and a corresponding region 432 corresponding to the second crotch joint 332). The absorbent pad 2 is attached to the wearing article 1 by joining the plurality of joints 30 to the plurality of corresponding regions 40 respectively.

[0136] In addition, the back sheet 22 may be configured so that the region other than the corresponding region 40 (non-corresponding region) can also be bonded to the bonding portion 30, but it is preferred that the corresponding region 40 is more strongly bonded to the bonding portion 30 than the non-corresponding region. In addition, from the perspective of convenience for the wearer who attaches the absorbent pad 2 to the wearing article 1, it is preferred that the corresponding region 40 is configured in a form that can be distinguished from the non-corresponding region (for example, a different raw material, coloring, etc. from the non-corresponding region).

[0137] [Effects of the First Embodiment]

[0138] In the wearing article 1, the coupling part 30 is provided not only at the two end parts (ventral part 101 and dorsal part 102) in the longitudinal direction L, but also at the crotch part 103 (crotch coupling part 33). Thus, in the state where the absorbent pad 2 is mounted on the wearing article 1 (hereinafter referred to as the "mounted state"), the displacement of the absorbent pad 2 relative to the wearing article 1 can be suppressed, and the absorbent pad 2 can be suppressed from being caught in the crotch of the wearer. That is, if the crotch coupling part 33 is not provided and the absorbent pad 2 can be separated from the wearing article 1 at the crotch of the wearer, there is a concern that only the absorbent pad 2 is caught in the crotch of the wearer due to the movement of the wearer, thereby causing distortion in the absorbent core 23a. By coupling the absorbent pad 2 to the wearing article 1 at the crotch coupling part 33, the above-mentioned situation can be avoided.

[0139] In addition, in the wearing article 1, the ventral joint portion 31, the crotch joint portion 33, and the back joint portion 32 are arranged separately from each other in the longitudinal direction L. This provides the following effects. The wearing article 1, which is a cloth underwear, generally has a force to contract in the longitudinal direction L. In the present embodiment, by providing an elastic member 14 along the leg opening portion 13 of the wearing article 1, the crotch portion 103 in particular is made to contract easily in the longitudinal direction L. Therefore, assuming that the joint portion (the portion joined to the wearing article 1) is provided on the entire back side of the absorbent pad 2 (for example, in the case where the entire back side of the absorbent pad 2 is bonded to the wearing article 1, etc.), it is difficult to attach the absorbent pad 2 to the wearing article 1 in a state contracted in the longitudinal direction L in a natural state (hereinafter referred to as a "contracted state"). That is, in order to properly attach the absorbent pad 2 to the wearing article 1, it is necessary to attach the absorbent pad 2 in a state where the wearing article 1 is stretched in the longitudinal direction L. However, in this case, there is a concern that the wearing article 1 cannot be fully stretched and wrinkles may appear on the bonding surface (adhesive surface, etc.) between the absorbent pad 2 and the wearing article 1. In addition, since the bonding surface has a large area, it is not easy to remove the absorbent pad 2 from the wearing article 1. In contrast, in the absorbent pad 2 described above, since the bonding portions 30 of the two end portions (ventral portion 101 and back portion 102) and the crotch portion 103 arranged in the longitudinal direction L are separated from each other, the absorbent pad 2 can be easily attached to the wearing article 1 in a contracted state. In addition, compared with the case where the entire back surface of the absorbent pad 2 is bonded to the wearing article 1 as described above, the bonding surface area can be reduced, so the absorbent pad 2 can be easily removed from the wearing article 1. According to the above, the wearing article 1 having the ventral joint 31, the dorsal joint 32 and the crotch joint 33 separated from each other in the length direction L can easily remove the absorbent pad 2 while suppressing the occurrence of distortion of the absorbent pad 2 when worn.

[0140] Furthermore, the wearing article 1 has a specific bonding structure (a structure in which the bonding at the crotch bonding part 33 is weaker than the bonding at the ventral bonding part 31 and the bonding at the back bonding part 32). Generally, a relatively high bonding force (strength of bonding to the absorbent pad 2) is required at the ventral bonding part 31 and the back bonding part 32. For example, the bonding force of the ventral bonding part 31 and the bonding force of the back bonding part 32 are set to such a degree that when the wearing article 1 and the absorbent pad 2 are moved together in order to fit the wearing article 1 to the wearer's body, the two ends of the absorbent pad 2 in the longitudinal direction L (i.e., the portions bonded by the ventral bonding part 31 and the back bonding part 32) will not be detached from the wearing article 1 due to friction with the wearer's body. Therefore, if the same bonding force as that of the ventral bonding part 31 and the back bonding part 32 is also given to the crotch bonding part 33, the absorbent pad 2 will be strongly bonded to the wearing article 1 in the entire area of ​​the ventral side, the back side and the crotch, and it will be difficult to remove the absorbent pad 2 from the wearing article 1. In contrast, in the wearing article 1, since the plurality of joints 30 have the above-mentioned specific joint structure, the wearing article 1 and the absorbent pad 2 can be reliably joined at the ventral joint 31 and the dorsal joint 32, and the absorbent pad 2 can be easily removed from the wearing article 1 at the crotch joint 33. In addition, as described below, the absorbent pad 2 can also be easily attached at the crotch joint 33. That is, first, the absorbent pad 2 (corresponding region 41 and corresponding region 43) is joined to the ventral joint 31 and the dorsal joint 32 of the wearing article 1 in a contracted state. At this time, due to the contraction of the wearing article 1 in the longitudinal direction L, there is a possibility that the crotch joint 33 is not joined to the appropriate position (corresponding region 43) of the absorbent pad 2. Even in this case, by forcibly stretching the wearing article 1 in the state of being bonded to the absorbent pad 2 by the ventral bonding part 31 and the dorsal bonding part 32 in the longitudinal direction L, the bonding between the absorbent pad 2 and the wearing article 1 at the crotch bonding part 33 is temporarily released, and when the wearing article 1 is sufficiently stretched in the longitudinal direction L to be in a state where the crotch bonding part 33 is in contact with the absorbent pad 2 (i.e., the crotch bonding part 33 faces the appropriate mounting position (corresponding area 43) in the absorbent pad 2), the crotch bonding part 33 and the absorbent pad 2 can be bonded again. As described above, by using the wearing article 1 having a specific bonding structure, the absorbent pad 2 can be easily attached and detached while suppressing the occurrence of distortion of the absorbent core in the wearing state.

[0141] The following describes the detailed structure of each part of this embodiment and the effects that can be obtained by the structure.

[0142] As described above, the ventral joint 31, the crotch joint 33 (the first crotch joint 331 and the second crotch joint 332 in the present embodiment) and the dorsal joint 32 are separated from each other in the length direction L. Thus, a non-bonding area UR1 (first non-bonding area) where no joint 30 exists is formed between the ventral joint 31 and the crotch joint 33 (the first crotch joint 331 disposed on the ventral side of the crotch joint 33 in the present embodiment). In addition, a non-bonding area UR2 (second non-bonding area) where no joint 30 exists is formed between the dorsal joint 32 and the crotch joint 33 (the second crotch joint 332 disposed on the dorsal side of the crotch joint 33 in the present embodiment). The total length of the non-bonding area UR1 and the non-bonding area UR2 in the length direction L (i.e., "D1+D2") is more than half of the distance D between the ventral joint 31 and the dorsal joint 32. That is, the plurality of joints 30 are arranged so that "D1+D2>D / 2" holds true. According to the above structure, the size (size in the length direction L) of the non-joined regions UR1 and UR2 can be sufficiently ensured between the ventral joint 31 and the dorsal joint 32. As a result, when the absorbent pad 2 is attached to and detached from the wearing article 1 as described above, the force required to stretch the wearing article 1 in the length direction L can be reduced. As a result, the absorbent pad 2 can be attached to and detached from the wearing article 1 more easily.

[0143] like Figure 1 As shown, the ventral joint portion 31 is arranged in the longitudinal direction L between the end portion 101a of the ventral portion 101 opposite to the crotch portion 103 and the leg opening portion 13 of the ventral portion 101 (ie, Figure 1 According to the above structure, the ventral joint part 31 can be arranged at a position sufficiently close to the ventral end (front end 101a) (that is, a position close to the position where the ventral end of the absorbent pad 2 is arranged). As a result, the ventral end of the absorbent pad 2 can be appropriately positioned and fixed by the ventral joint part 31.

[0144] The ventral part 101 has an elastic member 15 which is provided along the front end part 101a and contracts in the width direction W in a manner of tightening the waist of the wearer when worn, and the ventral joint part 31 is arranged at a position closer to the crotch part 103 than the elastic member 15 in the length direction L. That is, the ventral joint part 31 is arranged so as not to overlap with the elastic member 15. According to the above structure, it is possible to prevent the contraction of the elastic member 15 from being hindered by the ventral joint part 31, and it is possible to prevent the ventral joint part 31 from contracting in the width direction W due to the influence of the elastic member 15 (as a result, it is difficult to connect the absorbent pad 2 to the ventral joint part 31).

[0145] like Figure 1 As shown, the width L1 of the ventral joint portion 31 (the length of the ventral joint portion 31 in the width direction W) is shorter than the width Lmin of the narrowest portion 17 of the main body portion 10. Figure 5 As shown, the width of the absorbent pad 2 is usually shorter than the width Lmin of the narrowest portion 17. That is, when viewed from the thickness direction T, the wearing article 1 has a shape larger than the absorbent pad 2. Therefore, even if the width L1 of the ventral joint portion 31 is increased to be longer than the width Lmin of the narrowest portion 17, such a longer extending portion does not overlap with the absorbent pad 2 and is not connected to the absorbent pad 2, so it will be wasted. In addition, in the case where the ventral joint portion 31 is formed of a raw material that is harder than the fabric of the main body 10, there is a concern that the larger the area of ​​the ventral joint portion 31, the stronger the discomfort felt by the wearer when wearing it. As described above, by setting the width L1 of the ventral joint portion 31 in a manner that satisfies "width L1<width Lmin", the waste and discomfort described above can be suppressed.

[0146] like Figure 1 As shown, the back joint portion 32 is arranged in the length direction L between the end portion 102a of the back portion 102 opposite to the crotch portion 103 and the leg opening portion 13 of the back portion 102 (ie, Figure 1 According to the above structure, the back side joint part 32 can be arranged at a position close enough to the back side end (rear end 102a) (that is, a position close to the position where the back side end of the absorbent pad 2 is arranged). As a result, the back side joint part 32 can be used to appropriately position and fix the back side end of the absorbent pad 2.

[0147] The back portion 102 has an elastic member 16, which is provided along the rear end portion 102a and contracts in the width direction W in a manner that tightens the waist of the wearer when the wearer is in the wearing state, and the back joint portion 32 is arranged at a position closer to the crotch portion 103 than the elastic member 16 in the length direction L. That is, the back joint portion 32 is arranged so as not to overlap with the elastic member 16. According to the above structure, it is possible to prevent the contraction of the elastic member 16 from being hindered by the back joint portion 32, and it is possible to prevent the back joint portion 32 from contracting in the width direction W due to the influence of the elastic member 16 (as a result, it is difficult to connect the absorbent pad 2 to the back joint portion 32).

[0148] The width L2 of the back joint 32 (the length of the back joint 32 in the width direction W) is shorter than the width Lmin of the narrowest portion 17 of the main body 10. For the above reasons, even if the width L2 of the back joint 32 is increased to be longer than the width Lmin of the narrowest portion 17, such a longer extended portion does not overlap with the absorbent pad 2 and is not connected to the absorbent pad 2, so it will be wasted. In addition, in the case where the back joint 32 is formed of a raw material that is harder than the fabric of the main body 10, there is a concern that the larger the area of ​​the back joint 32, the greater the discomfort felt by the wearer when wearing it. As described above, by setting the width L2 of the back joint 32 in a manner that satisfies "width L2<width Lmin", the above-mentioned waste and discomfort can be suppressed.

[0149] The crotch joint 33 extends along the width direction W, and the lateral width L31 of the crotch joint 33 (the length of the crotch joint 33 in the width direction W) is longer than the longitudinal width L32 of the crotch joint 33 (the length of the crotch joint 33 in the length direction L). According to the above structure, the crotch joint 33 extending along the width direction W can be used to effectively suppress the movement (distortion, etc.) of the absorbent pad 2 (the part connected to the crotch joint 33) in the width direction W. In addition, in the case where the crotch joint 33 has a plurality of joints separated in the length direction L (the first crotch joint 331 and the second crotch joint 332 in the present embodiment) as in the present embodiment, the longitudinal width L32 of the crotch joint 33 does not refer to the width obtained by adding the longitudinal widths of the plurality of joints (the first crotch joint 331 and the second crotch joint 332 in the present embodiment), but refers to the longitudinal width of a single joint.

[0150] The lateral width L31 of the crotch joint 33 is shorter than the width L1 of the ventral joint 31 and the width L2 of the dorsal joint 32. According to the above structure, by making the width L1 of the ventral joint 31 and the width L2 of the dorsal joint 32 arranged at both ends in the longitudinal direction L relatively long, the wearing article 1 and the absorbent pad 2 can be firmly joined. On the other hand, by making the lateral width L31 of the crotch joint 33 arranged in the crotch portion that has a greater impact on the wearer's wearing feeling relatively short, the discomfort of the crotch portion felt by the wearer when wearing can be reduced.

[0151] The lateral width L31 of the crotch joint 33 is shorter than the width Lmin of the narrowest portion 17 of the main body 10. For the above reasons, even if the lateral width L31 of the crotch joint 33 is increased to be longer than the width Lmin of the narrowest portion 17, the longer extended portion does not overlap with the absorbent pad 2 and is not connected to the absorbent pad 2, so it will be wasted. In addition, in the case where the crotch joint 33 is formed of a raw material that is harder than the fabric of the main body 10, there is a concern that the larger the area of ​​the crotch joint 33, the stronger the discomfort felt by the wearer when wearing it. As described above, by setting the lateral width L31 of the crotch joint 33 in a manner that satisfies "lateral width L31<width Lmin", the above-mentioned waste and discomfort can be suppressed.

[0152] The distance from the first end 33a in the width direction W of the crotch joint 33 to the second end 33b on the opposite side of the first end 33a in the width direction W of the crotch joint 33 (in this embodiment, the lateral width L31 of the crotch joint 33) is 1 / 3 or more of the width Lmin of the narrowest portion 17 of the main body 10. According to the above structure, by ensuring that the lateral width L31 of the crotch joint 33 is greater than a certain level, the movement (distortion, etc.) of the absorbent pad 2 (the portion joined to the crotch joint 33) in the width direction W can be effectively suppressed.

[0153] The crotch joint portion 33 includes a first crotch joint portion 331 and a second crotch joint portion 332. The first crotch joint portion 331 is disposed at a position closer to the ventral portion 101 than the second crotch joint portion 332 in the longitudinal direction L. According to the above structure, by forming the crotch joint portion 33 by a plurality of joints (the first crotch joint portion 331 and the second crotch joint portion 332), the absorbent pad 2 in the worn state can be more effectively prevented from being sandwiched into the crotch of the wearer, and the occurrence of distortion of the absorbent core 23a can be more effectively prevented.

[0154] The first crotch joint 331 is arranged at a position closer to the ventral portion 101 than the central position (i.e., the center line CL) in the longitudinal direction L of the main body 10. On the other hand, the second crotch joint 332 is arranged at a position closer to the back portion 102 than the center line CL. In the wearing state, usually, the wearer's urination opening is located at a position closer to the ventral side than the center line CL in the crotch portion 103, and the wearer's defecation opening is located at a position closer to the back side than the center line CL in the crotch portion 103. Therefore, according to the above structure, by arranging the first crotch joint 331 and the second crotch joint 332 in a manner corresponding to the urination opening and the defecation opening, respectively, it is possible to suppress the occurrence of distortion of the absorbent core 23a at a position close to the urination opening and the defecation opening. As a result, the absorption leakage of excrement can be appropriately suppressed.

[0155] The first crotch joint portion 331 and the second crotch joint portion 332 are arranged asymmetrically with respect to the center line CL. In other words, when the main body 10 is folded in half along the center line CL, the first crotch joint portion 331 and the second crotch joint portion 332 are arranged in a manner that they do not completely overlap. More specifically, Figure 1 As shown, in the length direction L, the distance D3 from the first crotch joint 331 to the center line CL is longer than the distance D4 from the second crotch joint 332 to the center line CL. That is, the first crotch joint 331 disposed on the ventral side is disposed at a position farther from the center line CL than the distance from the second crotch joint 332 disposed on the dorsal side to the center line CL. In addition, in the length direction L, the distance D1 from the ventral joint 31 to the first crotch joint 331 is shorter than the distance D2 from the second crotch joint 332 to the dorsal joint 32. Usually, in the wearing state, the position of the crotch portion 103 opposite to the wearer's urination port is farther from the center line CL than the position of the crotch portion 103 opposite to the wearer's defecation port. That is, the distance from the center line CL to the position corresponding to the urination port (the position closer to the ventral side than the center line CL) is greater than the distance from the center line CL to the position corresponding to the defecation port (the position closer to the dorsal side than the center line CL). Therefore, according to the above structure, the first crotch joint part 331 can be brought close to the position corresponding to the urination opening, and the second crotch joint part 332 can be brought close to the position corresponding to the defecation opening. As a result, the occurrence of distortion of the absorbent core 23a can be effectively suppressed at a position closer to the urination opening and the defecation opening, and the absorption leakage of excrement can be further effectively suppressed.

[0156] The stiffness of the first part is lower than the stiffness of the second part and the stiffness of the third part. The first part is composed of the part of the main body 10 overlapping with the crotch joint 33 and the crotch joint 33, the second part is composed of the part of the main body 10 overlapping with the ventral joint 31 and the ventral joint 31, and the third part is composed of the part of the main body 10 overlapping with the dorsal joint 32 and the dorsal joint 32. The above-mentioned "stiffness" is, for example, a value measured by the cantilever method. The first part of the main body 10 is the part opposite to the crotch of the wearer, so it is sought to be flexibly deformed according to the movement of the wearer when wearing. According to the above structure, by making the stiffness of such a first part lower than the stiffness of the second part and the stiffness of the third part, the part of the absorbent core 23a opposite to the first part can be flexibly deformed together with the wearing article 1.

[0157] In the present embodiment, the stiffness of the crotch joint 33 itself is lower than the stiffness of the ventral joint 31 itself and the stiffness of the dorsal joint 32 itself. According to the above structure, by adjusting the stiffness of the joint 30, it is easy to achieve the structure in which the stiffness of the first part is lower than the stiffness of the second part and the stiffness of the third part.

[0158] Next, the structure of the connecting portion 30 is described in detail. The structure of the connecting portion 30 (i.e., the means and method of connecting the absorbent pad 2 and the wearing article 1) is not limited to a specific structure. In addition, as long as the corresponding area 40 of the absorbent pad 2 corresponding to the connecting portion 30 is provided with a structure corresponding to the structure of the connecting portion 30. Several specific examples of the connecting portion 30 are listed below.

[0159] As a first example, the coupling portion 30 may be formed by a hook member (e.g., a hook portion of a so-called Velcro tape) including a plurality of pins having claws at the top end. In this case, the corresponding region 40 may be formed by a member (e.g., a loop portion of a so-called Velcro tape) coupled (engaged) to the hook member.

[0160] As a second example, the connecting portion 30 may be formed of an adhesive structure. The adhesive structure may be formed of, for example, an adhesive surface having an adhesive material such as a hot melt adhesive (HMA) provided on the surface.

[0161] As a third example, the coupling part 30 may be formed of a member having magnetic force (eg, a magnet), and any magnetic material or the like that attracts the coupling part 30 by magnetic force may be provided in the corresponding region 40 .

[0162] As a fourth example, the coupling portion 30 may be formed by one member (convex portion or concave portion) of a snap button. It is sufficient if another member (concave portion or convex portion) of the snap button is provided in the corresponding region 40 .

[0163] As a fifth example, the joint 30 may be formed of a friction resistance member that engages with the wearing article 1 by utilizing friction resistance. Examples of the friction resistance member include a raised raw material configured to increase the contact area, or a member having a concave-convex structure on the surface. Specific examples of the friction resistance member include a raw material formed of NANOFRONT (registered trademark), etc.

[0164] As a sixth example, the connecting portion 30 may be formed of a rubber material. For example, the connecting portion 30 may be formed of a super strong double-sided tape, a rubber non-slip member, or the like.

[0165] Next, several configuration examples for realizing the above-mentioned specific connection structure will be described.

[0166] (First structural example)

[0167] The specific bonding structure can be realized by making the area of ​​the crotch joint 33 smaller than the area of ​​the ventral joint 31 and the area of ​​the dorsal joint 32. Here, in the case where the crotch joint 33 is composed of a plurality of joints (the first crotch joint 331 and the second crotch joint 332) as in the present embodiment, the area of ​​the crotch joint 33 refers to the single area of ​​the above-mentioned plurality of joints. That is, in the present embodiment, the specific bonding structure is realized by making the first crotch joint 331 and the second crotch joint 332 have an area smaller than the area of ​​the ventral joint 31 and the dorsal joint 32, respectively. According to the first structural example, the specific bonding structure can be realized relatively easily by making the crotch joint 33 and the ventral joint 31 and the crotch joint 33 and the dorsal joint 32 have an area difference.

[0168] As a specific implementation method of the first structural example, it may be that, in the width direction W, the length of the crotch joint 33 (i.e., the lateral width L31) is made shorter than the length of the ventral joint 31 (i.e., the width L1) and the length of the dorsal joint 32 (i.e., the width L2). According to the above structure, the construction of the first structural example can be easily realized. In addition, by making the lateral width L31 of the crotch joint 33 arranged in the crotch part 103 shorter than the widths L1 and L2 of the joints at the two end parts in the length direction L (the ventral joint 31 and the dorsal joint 32), the discomfort of the wearer during wearing due to the crotch joint 33 can be suppressed.

[0169] (Second structural example)

[0170] In the case where the first example is adopted as the structure of the joint part 30, a specific joint structure can also be realized by making the joint structure of the crotch joint part 33 different from the joint structure of the ventral joint part 31 and the joint structure of the dorsal joint part 32 in terms of the number, height, material and shape of the claw of the pin. Several examples of methods for making the joint structure different between the crotch joint part 33 and the ventral joint part 31 and between the crotch joint part 33 and the dorsal joint part 32 as described above are shown below. For example, the height of the pins of the ventral joint part 31 and the height of the pins of the dorsal joint part 32 can be made higher than the height of the pins of the crotch joint part 33. In addition, the number of pins of the ventral joint part 31 and the number of pins of the dorsal joint part 32 can be made larger than the number of pins of the crotch joint part 33. In addition, the joint strength of the crotch joint part 33 can be made higher than the joint strength of the ventral joint part 31 and the joint strength of the dorsal joint part 32 by combining the number, height, material and shape of the claw of the pins described above. According to the above configuration, by making the connection structures of the connection parts 30 (ventral connection part 31, back connection part 32 and crotch connection part 33) composed of hooks different, a specific connection structure can be easily realized.

[0171] (Third structural example)

[0172] When the above-mentioned second example is adopted as the structure of the joint 30, a specific joint structure can be achieved by, for example, making the coating unit area weight, coating area, coating pattern, etc. of the adhesive material different between the crotch joint 33 and the ventral joint 31 and between the crotch joint 33 and the dorsal joint 32.

[0173] (Structural Example 4)

[0174] When the above-mentioned third example is adopted as the structure of the joint 30, a specific joint structure can be achieved by, for example, making the magnetic force, area, etc. of the component having a magnetic force different between the crotch joint 33 and the ventral joint 31 and between the crotch joint 33 and the dorsal joint 32.

[0175] (Fifth structural example)

[0176] When the above-mentioned fourth example is adopted as the structure of the joint 30, a specific joint structure can be achieved by, for example, making the number and area of ​​the configured buttons different between the crotch joint 33 and the ventral joint 31 and between the crotch joint 33 and the dorsal joint 32.

[0177] (Sixth structural example)

[0178] A specific connection structure can also be realized by making the connection method of the crotch connection part 33 (for example, the methods corresponding to the above-mentioned first to sixth examples, respectively) different from the connection method of the ventral connection part 31 and the connection method of the dorsal connection part 32. According to the above structure, by making the connection method between the crotch connection part 33 and the ventral connection part 31 and between the crotch connection part 33 and the dorsal connection part 32 different, a specific connection structure can be easily realized.

[0179] As a specific example of the sixth structural example, the following structural examples can be cited. That is, a specific bonding structure can also be realized by adopting the above-mentioned first example as the structure of the ventral bonding part 31 and the structure of the dorsal bonding part 32 and adopting the above-mentioned fifth example as the structure of the lower crotch bonding part 33. According to the above structure, it is possible to use a relatively simple structure to provide an appropriate bonding strength difference between the ventral bonding part 31 and the lower crotch bonding part 33 and between the dorsal bonding part 32 and the lower crotch bonding part 33.

[0180] [Second embodiment]

[0181] Reference Figure 7 and Figure 8 The structure of the wearing article 1A according to the second embodiment will be described. Figure 7 This is a plan view of the wearing article 1A as viewed from the skin side. Figure 8It is a schematic representation of the Figure 7 FIG. 1 is a diagram showing a cross-sectional structure of a wearing article 1A taken along line VIII-VIII.

[0182] The wearing article 1A is different from the wearing article 1 in that pockets 18 are provided in each of the abdominal portion 101 and the dorsal portion 102, and the other structures are the same as those of the wearing article 1. Alternatively, the pocket 18 may be provided in only one of the abdominal portion 101 and the dorsal portion 102.

[0183] Each pocket 18 is configured to accommodate the end 2a of the absorbent pad 2 in the longitudinal direction L and to cover the outer surface of the end 2a (i.e., the surface 21a of the surface sheet 21) in the stored state with the end 2a accommodated. In the present embodiment, as an example, the pocket 18 is arranged in the thickness direction T (refer to Figure 8 ) has a rectangular shape when viewed from the thickness direction T. The outer portion in the width direction W and the outer portion in the length direction L of the edge of the bag portion 18 are formed with a fixing portion 18a ( Figure 7 On the other hand, the inner portion of the edge of the pocket portion 18 in the longitudinal direction L as viewed from the thickness direction T is not fixed to the inner surface 10a of the main body portion 10, forming an opening into which the absorbent pad 2 can be inserted.

[0184] According to the wearing article 1A having the pocket portion 18 as described above, the absorbent pad 2 can be more stably attached to the wearing article 1 and the absorbent pad 2 can be easily positioned relative to the wearing article 1 .

[0185] like Figure 7As shown, when viewed from the thickness direction T, which is the direction in which the main body 10 and the joint 30 overlap, the ventral pocket 18 covers at least a portion of the ventral joint 31. In this embodiment, the ventral pocket 18 covers the entire ventral joint 31. That is, in the thickness direction T, the ventral pocket 18 overlaps the entire ventral joint 31. Similarly, when viewed from the thickness direction T, the dorsal pocket 18 covers at least a portion of the dorsal joint 32. In this embodiment, the dorsal pocket 18 covers the entire dorsal joint 32. That is, in the thickness direction T, the dorsal pocket 18 overlaps the entire dorsal joint 32. According to the above structure, it is possible to prevent the ventral joint 31 and the dorsal joint 32, which have a relatively strong bonding force (i.e., a bonding force stronger than the crotch joint 33), from accidentally bonding (adhering) to a member other than the absorbent pad 2 or a part of the wearing article 1 itself when the absorbent pad 2 is not installed. The above-mentioned effect can also be achieved by using the bag portion 18 to cover at least a portion of the joint 30 (the ventral joint 31 or the dorsal joint 32), but the bag portion 18 covering the entire joint 30 (the ventral joint 31 or the dorsal joint 32) can achieve a further higher effect.

[0186] Here, consider a case where the ventral joint 31 and the dorsal joint 32 have a structure (the structure of the first example) in which a plurality of pins each have a claw portion at the tip. In this case, the fabric of the inner side 18b (first side) of the surface 21a of the pocket 18 facing the end 2a of the absorbent pad 2 in the stored state can be made of a fiber thicker than the protruding width of the claw portion. In this case, the claw portion is not easily engaged with the inner side 18b. Therefore, according to the above structure, it is possible to prevent the inner side 18b from being fixed to the ventral joint 31 or the dorsal joint 32 when the absorbent pad 2 is not attached to the wearing article 1 (i.e., the inner side 18b is directly opposite to the ventral joint 31 or the dorsal joint 32). As a result, when inserting the absorbent pad 2 into the pocket 18, the pocket 18 is easy to open, so the convenience of the wearer who attaches the absorbent pad 2 to the wearing article 1 can be improved.

[0187] The fabric of the inner side 18b constituting the pocket 18 may also be a film. In this case, it is also possible to prevent the inner side 18b from being fixed to the ventral joint 31 or the dorsal joint 32, and the same effect as above can be obtained.

[0188] In addition, the inner side surface 18b of the pocket portion 18 may also be hydrophobic. For example, the inner side surface 18b may be waterproofed. According to the above structure, when the excrement of the wearer absorbed by the absorbent pad 2 leaks into the pocket portion 18 through the end portion 2a of the absorbent pad 2, the excrement can be prevented from seeping out to the outer surface 18c of the pocket portion 18.

[0189] On the other hand, the outer surface 18c (second surface) of the bag portion 18 facing the skin of the wearer when worn may also be hydrophilic. For example, the outer surface 18c may be made of a fabric (e.g., a fabric made of natural fibers such as cotton or constituent fibers such as polyester) that accumulates water in the gaps between threads and fabrics and exhibits a hydrophilic function. According to the above structure, by making the outer surface 18c facing the skin of the wearer hydrophilic, sweat absorption can be improved, thereby improving the wearing feeling of the wearing article 1.

[0190] [Variation of the Second Embodiment]

[0191] Reference Fig. 9 A modification of the second embodiment will be described. This modification differs from the second embodiment in that it includes a pocket portion 18A instead of the pocket portion 18 and a ventral joint portion 131 instead of the ventral joint portion 31, and the other structures are the same as those of the second embodiment. Fig. 9 (A) is a top view of the portion where the bag portion 18A is arranged. Fig. 9 (B) schematically shows the Fig. 9 In addition, in this modification, the portion consisting of the ventral bag portion 18A and the ventral joint portion 31 is described, but the portion consisting of the dorsal bag portion 18A and the dorsal joint portion 32 may also be constructed in the same manner.

[0192] In this modified example, the plurality of coupling parts 30 further include a bag coupling part 34 provided on the inner side surface 18b (first surface) of the bag part 18A. In addition, the bag coupling part 34 is in contact with the surface 21a (refer to Figure 8 ) is combined. That is, the pocket joint part 34 has a surface that can be combined with the surface 21a of the absorbent pad 2. According to the above structure, the wearing article 1A and the absorbent pad 2 can be combined in a manner that the absorbent pad 2 is sandwiched by the pocket joint part 34 and the ventral joint part 131. As a result, the bonding strength between the wearing article 1 and the absorbent pad 2 can be improved.

[0193] In addition, in this modification, the bag joint portion 34 is arranged so as not to overlap with the ventral joint portion 131 in the thickness direction T. As an example, Fig. 9As shown in (A), the bag joint 34 has a plurality of (two in this modified example) parts 34a, 34b arranged in a manner separated from each other in the width direction W. In addition, the ventral joint 131 has a plurality of (three in this modified example) parts 131a, 131b, 131c arranged in a manner separated from each other in the width direction W. The parts 34a, 34b and the parts 131a, 131b, 131c are arranged alternately along the width direction W. That is, the parts 34a, 34b and the parts 131a, 131b, 131c are arranged in a manner not to overlap each other in the thickness direction T. If the thickness of the wearing article 1A is large, the rigidity is high in the portion with a large thickness, and the flexibility is impaired. On the other hand, according to the above-mentioned structure, the wearing article 1A and the absorbent pad 2 can be firmly connected by using the pocket connecting portion 34 and the abdominal connecting portion 131, and by arranging the pocket connecting portion 34 and the abdominal connecting portion 131 in a manner not to overlap each other, an increase in the thickness of the wearing article 1A caused by overlapping of the connecting portions 30 can be suppressed, and the softness of the wearing article 1A can be ensured.
