Description

worn articles

The present disclosure relates to wearable articles.

BACKGROUND ART Conventionally, wearable articles such as cloth underwear that are used with disposable absorbent pads attached inside are known. For example, in Patent Document 1, a wear article (outer cover) worn around the wearer's lower torso is attached to the inner surface (skin side) through hook and loop fasteners provided at both longitudinal ends of the outer cover. A configuration for attaching an absorbent pad (absorbent insert) is disclosed.

Special table 2013-534457 publication

As disclosed in Patent Document 1, in a method in which only the longitudinal ends of an absorbent pad are fixed (bonded) to a worn article, the absorbent pad is not caught between the wearer's crotch area when worn. This may cause the absorbent core arranged inside the absorbent pad to twist. As a result, urine leakage may occur more easily.

On the other hand, in order to avoid the occurrence of twisting of the absorbent core as described above, the entire back surface of the absorbent pad (the surface facing the inner surface of the worn article) is attached to the inner surface of the worn article with adhesive tape (such as double-sided tape). When an adhesion (bonding) method is adopted, it becomes difficult to attach the entire back surface of the absorbent pad to a wearing article without wrinkles. In other words, when a wearable article that is stretchable in the longitudinal direction is used, if an absorbent pad is attached to the wearable article while it is shrunk (unstretched) in the longitudinal direction, the relationship between the wearable article and the absorbent pad is There is a risk that misalignment or wrinkles may occur on the adhesive surface. Furthermore, if the adhesive area between the wearing article and the absorbent pad is large, the flexibility and wearing feeling 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.

Accordingly, one aspect of the present disclosure provides a wearable article that is used in combination with an absorbent pad, which allows the absorbent pad to be easily attached and detached while suppressing the occurrence of twisting of the absorbent pad in the worn state. The purpose is to provide.

A wearable article according to one aspect of the present disclosure is a reusable cloth underwear worn around the lower torso of the wearer via an absorbent pad, the wearable article being worn by the wearer. a ventral part located on the ventral side of the wearer in the worn state, a dorsal part located on the back of the wearer in the worn state, and a crotch part located between the ventral part and the dorsal part; and a plurality of coupling parts that are provided on the inner surface of the main body part facing the absorbent pad in the worn state and configured to be able to be coupled with the absorbent pad, and the plurality of coupling parts are arranged on the ventral side. The ventral side joint part provided in the part, the dorsal side joint part provided in the dorsal part, and the crotch joint part provided in the crotch part, and the ventral part, the crotch part, and the dorsal part. In the longitudinal direction, which is the direction in which they are lined up, the ventral joint, the crotch joint, and the dorsal joint are spaced apart from each other.

According to the present disclosure, it is an object of the present disclosure to provide a wearing article that is used in combination with an absorbent pad, in which the absorbent pad can be easily attached and detached while suppressing the occurrence of twisting of the absorbent pad in the worn state. Can be done.

[Embodiment]
Embodiments of the present disclosure will be described in detail below with reference to the drawings. In the following description, the same or equivalent elements will be denoted by the same reference numerals, and overlapping description will be omitted.

[First embodiment]
The configuration of the wearing article 1 according to the first embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a plan view of a wearing article 1 viewed from the skin side. FIG. 2 is a plan view of the wearing article 1 viewed from the non-skin side. FIGS. 1 and 2 show a state in which the wearing article 1 is stretched to the point where no wrinkles are formed (hereinafter referred to as the "stretched state"). In this embodiment, the wearing article 1 is a tape-type cloth underwear.

In this embodiment, the "wearer" is a person who wears the wearing article 1 to which the absorbent pad 2 is attached. The "skin side" is the side that faces the skin of the wearer when the absorbent pad 2 is worn by the wearer together with the wearing article 1 (hereinafter referred to as "wearing state"). The "non-skin side" is the side that faces away from the wearer's skin in the worn state.

In the following, the longitudinal direction of the wearing article 1 in the stretched state (see FIGS. 1 and 2) will be referred to as the "longitudinal direction L", and the lateral direction of the absorbent pad 2 perpendicular to the longitudinal direction L will be referred to as the "width direction W". The direction perpendicular to the longitudinal direction L and the width direction W is referred to as the "thickness direction T." Further, a straight line passing through the center of the wearing article 1 in the longitudinal direction L and parallel to the width direction W is referred to as a "center line CL." The longitudinal direction L is a direction extending from the front side (ventral side) of the wearer's body to the back side (dorsal side) of the wearer's body in the worn state. The width direction W is a direction that coincides with the left-right direction of the wearer in the worn state. The thickness direction T is the direction in which the materials constituting the wearing article 1 (the main body part 10, the joining part 30, etc. described later) are laminated.

The wearing article 1 is a reusable cloth underwear that is worn around the wearer's lower torso via an absorbent pad 2. The absorbent pad 2 is attached to the wearing article 1 and placed between the wearing article 1 and the wearer.

The wearing article 1 has a main body portion 10. As shown in FIGS. 1 and 2, the main body 10 has an inner surface 10a that faces the back surface of the absorbent pad 2 (back sheet 22, which will be described later) in the worn state, and an outer surface 10b opposite to the inner surface 10a. has. The main body part 10 includes a ventral part 101 located on the ventral side of the wearer in the worn state, a dorsal part 102 located on the dorsal side of the wearer in the worn state, and the ventral part 101 and the dorsal part 102. The crotch area 103 is located in between. The abdominal part 101, the crotch part 103, and the dorsal part 102 are lined up along the longitudinal direction L from the ventral side (front) to the dorsal side (backward) of the wearer. As an example, when the main body part 10 is divided into four equal parts in the longitudinal direction L, one region located most ventrally corresponds to the ventral part 101, and one region located most dorsally side corresponds to the ventral part 101. Two regions corresponding to the dorsal side part 102 and located between the ventral side part 101 and the dorsal side part 102 (that is, the central part in the longitudinal direction of the main body part 10) correspond to the crotch part 103.

Fixed portions 11 are provided at both ends of the inner surface 10a of the back side portion 102 in the width direction W. The fixing part 11 is constituted by, for example, a hook part of a hook-and-loop fastener. Furthermore, fixing parts 12 corresponding to the fixing parts 11 are provided at both ends of the outer surface 10b of the abdominal part 101 in the width direction W. The fixing part 12 is constituted by, for example, a loop part of a hook-and-loop fastener. As shown in FIG. 6, each fixing part 11 is coupled to each fixing part 12 in the worn state. As a result, the side edges in the width direction W of the entire area of the crotch area 103, a part of the ventral part 101 on the crotch part 103 side, and a part of the dorsal part 102 on the crotch part 103 side (range R in FIG. 1). The leg portion 13 is constructed by the following.

The leg portion 13 is a portion that forms an opening through which the wearer's legs are passed in the worn state. An elastic member 14 that contracts along the leg portion 13 is provided in a portion along the leg portion 13. Further, an elastic member 15 (abdominal elastic member) that contracts in the width direction W so as to tighten the wearer's waist when worn is provided along the front end 101a of the abdominal part 101. An elastic member 16 (back elastic member) that contracts in the width direction W so as to tighten the wearer's waist when worn is provided along the rear end 102a of the back side portion 102. The elastic members 14, 15, 16 are, for example, flat rubber, elastic sheets, or the like.

The main body part 10 is formed in a gourd shape (or hourglass shape) when viewed from the thickness direction T, and the width (length in the width direction W) of the main body part 10 is the minimum at the crotch part 103. A narrowest portion 17 is formed.

The inner surface 10a is provided with a plurality of coupling parts 30 configured to be able to be coupled with the absorbent pad 2. Note that "bonding" means being fixed to the absorbent pad 2 to the extent that it can be attached and detached, and includes various means such as engagement and adhesion. The coupling portion 30 may be constituted by, for example, a region including a plurality of pins (hook structure) having claw portions at the tips thereof. The plurality of joint parts 30 include a ventral joint part 31 , a dorsal joint part 32 , and a crotch joint part 33 . The ventral joint portion 31 is provided on the ventral portion 101 of the inner surface 10a. The back joint portion 32 is provided on the back side portion 102 of the inner surface 10a. The crotch joint portion 33 is provided at the crotch portion 103 of the inner surface 10a. In the longitudinal direction L, the ventral joint portion 31, the crotch joint portion 33, and the dorsal joint portion 32 are arranged apart from each other.

The plurality of joint parts 30 have a structure in which the joint at the crotch joint part 33 is weaker than the joint at the ventral joint part 31 and the joint at the dorsal joint part 32 (hereinafter referred to as "specific joint structure"). In other words, when the absorbent pad 2 is coupled to the wearing article 1 via the plurality of coupling parts 30, the force required to release the coupling between the absorbent pad 2 and the wearing article 1 at the crotch coupling part 33 is The force is configured to be smaller than the force required to release the bond between the absorbent pad 2 and the wearing article 1 at the ventral side bonding portion 31 or the dorsal side bonding portion 32. A specific example of the configuration of the coupling section 30 will be described later.

As an example, the ventral joint portion 31 and the dorsal joint portion 32 have the same rectangular shape when viewed from the thickness direction T. The ventral side joint part 31 and the dorsal side joint part 32 are formed in a rectangular shape extending in the width direction W (that is, a rectangular shape whose length in the width direction W is longer than the length in the longitudinal direction L). The crotch joint 33 (in this embodiment, each of a first crotch joint 331 and a second crotch joint 332 described later) is the ventral joint 31 and the dorsal joint when viewed from the thickness direction T. It has a rectangular shape smaller than 32. The crotch joint part 33 is also formed in a rectangular shape extending in the width direction W, similarly to the ventral joint part 31 and the dorsal joint part 32. As an example, the length of the crotch joint 33 in the longitudinal direction L matches the length of each of the ventral joint 31 and the dorsal joint 32 in the longitudinal direction L. On the other hand, the length of the crotch joint 33 in the width direction W is shorter than the length of each of the ventral joint 31 and the back joint 32 in the width direction W. The center positions of the ventral side joint part 31, the back side joint part 32, and the crotch joint part 33 in the width direction W coincide with the center position of the main body part 10 in the width direction W.

Next, the absorbent pad 2 to be attached to the wearing article 1 will be explained with reference to FIGS. 3 to 6. FIG. 3 is a plan view of the absorbent pad 2 viewed from the skin side. FIG. 4 is a plan view of the absorbent pad 2 viewed from the non-skin side. FIG. 5 is a plan view of the wearing article 1 to which the absorbent pad 2 is attached. FIG. 6 is a perspective view of the wearing article 1 to which the absorbent pad 2 is attached.

The absorbent pad 2 has a main body portion 20. As shown in FIGS. 3 and 4, the main body portion 20 has a rectangular outer shape when viewed from the thickness direction T in the extended state. The main body portion 20 includes a top sheet 21, a back sheet 22, and an absorbent body 23. Each member, such as the top sheet 21, the back sheet 22, and the absorber 23, may be joined to each other using a known material such as an adhesive.

The top sheet 21 is a liquid-permeable sheet that is placed on the wearer's skin side and faces the wearer's skin in the worn state. The top sheet 21 may be formed of, for example, a liquid-permeable nonwoven fabric or woven fabric, a synthetic resin film having liquid-permeable holes, a composite sheet thereof, or the like.

The back sheet 22 is a liquid-impermeable sheet that is placed on the non-skin side of the wearer and faces the wearing article 1 in the worn state. The back sheet 22 may be formed of, for example, a liquid-impermeable nonwoven fabric, a synthetic resin film, or a composite sheet thereof.

The absorbent body 23 is arranged between the top sheet 21 and the back sheet 22. The absorbent core 23 includes an absorbent core 23a and a core wrap (not shown) that covers the absorbent core 23a. The absorbent core 23a is a member that absorbs the wearer's excrement, and has liquid absorbing and liquid retaining properties. The absorbent core 23a is a laminate of absorbent material comprising, for example, ground pulp or super absorbent polymer (SAP), or a mixture thereof. The core wrap is, for example, tissue or a nonwoven sheet.

As shown in FIG. 3, as an example in this embodiment, the absorbent core 23a is formed in a gourd shape (or hourglass shape) when viewed from the thickness direction T, and the absorbent core 23a has a gourd shape (or an hourglass shape). The center portion in the longitudinal direction L has a constricted shape. That is, the width (length in the width direction W) of the absorbent core 23a is maximum in a portion including both ends of the ventral side and the dorsal side, and in a portion including approximately the center portion in the longitudinal direction L of the absorbent core 23a. It is the minimum in

A pair of leg side gathers 24 are provided on both sides of the main body portion 20 in the width direction W. The leg side gathers 24 extend along the longitudinal direction L over substantially the entire length of the main body portion 20 in the longitudinal direction L. At both ends of the leg side gathers 24 in the longitudinal direction L, fixing regions B (areas indicated by diagonal hatching in FIG. 3) where the leg side gathers 24 and the top sheet 21 are fixed to each other are provided. The leg side gathers 24 and the top sheet 21 are fixed (adhered) to each other in the fixing region B by, for example, pasting with an adhesive, ultrasonic bonding, thermal fusion using an embossing roll, or the like.

The leg side gathers 24 are configured to be able to stand up by contracting in the longitudinal direction L. More specifically, the leg side gathers 24 have an elastic member 25 extending along the longitudinal direction L between a pair of fixed regions B provided at both ends in the longitudinal direction L. As an example, the elastic member 25 is composed of one or more (three in this embodiment) rubber threads. The leg side gathers 24 can be erected by the elastic members 25 contracting in the longitudinal direction L. In the worn state, the elastic member 25 contracts and the leg side gathers 24 stand up, thereby suppressing the leakage of excrement to the outside of the main body portion 20 (lateral leakage). That is, when the leg side gathers 24 are in the upright state, a leak-proof cuff is formed to prevent excrement from leaking to the outside along the surface of the topsheet 21.

FIG. 3 shows a state in which the leg side gathers 24 are folded inward in the width direction W. Therefore, in FIG. 3, the top portion 24a of the leg side gathers 24 is located inside the outer end portion of the main body portion 20 in the width direction W. In this embodiment, as an example, the back sheet 22 is integrated with the leg side gathers 24. Thereby, the outer end portion of the main body portion 20 in the width direction W is aligned with the upright fulcrum 24b of the leg side gathers 24. The upright fulcrum 24b is the base portion (bending starting point) of the rising portion of the leg side gathers 24, and extends in the longitudinal direction L.

As shown in FIG. 5, the wearing article 1 has a larger shape 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. Further, the width of the absorbent pad 2 (length in the width direction W) is shorter than the width Lmin of the narrowest part 17 of the wearing article 1 (see FIG. 1). In this embodiment, the absorbent pad 2 is attached to a substantially central portion of the wearing article 1 in the longitudinal direction L and the width direction W. More specifically, as shown in FIG. 4, the surface 22a of the back sheet 22 of the absorbent pad 2 has a plurality of holes corresponding to each of the plurality of joints 30 provided on the inner surface 10a of the wearing article 1. A corresponding area 40 is provided. Each corresponding region 40 is a region having a surface that can be coupled to each coupling portion 30. The plurality of corresponding regions 40 include a corresponding region 41 corresponding to the ventral joint portion 31, a corresponding region 42 corresponding to the dorsal joint portion 32, and a corresponding region 43 corresponding to the crotch joint portion 33 (in this embodiment, a corresponding region 43 corresponding to the crotch joint portion 33). 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 coupling the plurality of coupling parts 30 to the corresponding plurality of corresponding regions 40, respectively.

Note that an area other than the compatible area 40 (non-compatible area) of the back sheet 22 may also be configured to be able to be combined with the joint part 30, but the compatible area 40 is more strongly connected to the joint part 30 than the non-compatible area. It is preferable that the In addition, from the viewpoint of convenience for the wearer who attaches the absorbent pad 2 to the wearable article 1, the compatible area 40 is designed in a manner that can be distinguished from the non-compatible area (for example, with a different material, color, etc.) from the non-compatible area. Preferably, the configuration is configured.

[Operations and effects of the first embodiment]
In the wearing article 1, joint portions 30 (crotch joint portions 33) are provided not only at both ends in the longitudinal direction L (ventral side portion 101 and back side portion 102) but also at the crotch portion 103. As a result, when the absorbent pad 2 is attached to the wearing article 1 (hereinafter referred to as the "attached state"), it is possible to suppress the positional shift of the absorbent pad 2 with respect to the wearing article 1, and the absorbent pad 2 is attached to the wearer. This can prevent it from being caught in the groin area of the person. That is, if the crotch joint 33 is not provided and the absorbent pad 2 is separable from the wearable article 1 in the wearer's crotch region, only the absorbent pad 2 will be worn by the wearer's movements. There is a risk that the absorbent core 23a may get stuck in the person's crotch area, causing twisting of the absorbent core 23a. By connecting the absorbent pad 2 to the wearing article 1 at the crotch joint 33, the above situation can be avoided.

Furthermore, in the wearing article 1, in the longitudinal direction L, the ventral joint portion 31, the crotch joint portion 33, and the back joint portion 32 are arranged apart from each other. This produces the following effects. The wearing article 1, which is cloth underwear, generally has the ability to shrink in the longitudinal direction L. In this embodiment, the elastic member 14 is provided along the leg portion 13 of the wearing article 1, so that the crotch region 103 in particular is easily contracted in the longitudinal direction L. Therefore, if a joining part (a part to be joined to the wearing article 1) is provided on the entire back surface of the absorbent pad 2 (for example, when the entire back surface of the absorbent pad 2 is glued to the wearing article 1), It is difficult to attach the absorbent pad 2 to the wearing article 1 which is in a state of being contracted in the longitudinal direction L in its natural state (hereinafter referred to as the "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 with the wearing article 1 stretched in the longitudinal direction L. If the absorbent pad 2 is not fully stretched, there is a possibility that wrinkles may be formed on the bonding surface (adhesive surface, etc.) between the absorbent pad 2 and the wearing article 1. Further, since the area of the bonding surface is large, it is not easy to remove the absorbent pad 2 from the wearing article 1. On the other hand, in the absorbent pad 2 described above, the joint parts 30 arranged at both ends in the longitudinal direction L (ventral part 101 and dorsal part 102) and the crotch part 103 are arranged apart from each other. Therefore, the absorbent pad 2 can be easily attached to the wearing article 1 in a contracted state. Furthermore, compared to the case where the entire back surface of the absorbent pad 2 is bonded to the wearing article 1 as described above, the area of the bonding surface can be made smaller, making it possible to easily remove the absorbent pad 2 from the wearing article 1. becomes. As described above, according to the wearing article 1 having the ventral side joint part 31, the dorsal side joint part 32, and the crotch joint part 33 which are spaced apart from each other in the longitudinal direction L, the occurrence of twisting of the absorbent pad 2 in the worn state is suppressed. At the same time, the absorbent pad 2 can be easily attached and detached.

Furthermore, the wearing article 1 has a specific joint structure (a structure in which the joint at the crotch joint 33 is weaker than the joints at the ventral joint 31 and the back joint 32). The ventral joint portion 31 and the dorsal joint portion 32 usually require relatively high binding strength (strength for binding with the absorbent pad 2). For example, when the wearing article 1 is moved together with the absorbent pad 2 in order to fit the wearing article 1 to the wearer's body, both ends of the absorbent pad 2 in the longitudinal direction L ( That is, the bonding force of the ventral side joint part 31 and the dorsal side joint part 32 is set to such an extent that the part joined by the ventral side joint part 31 and the dorsal side joint part 32 does not come off from the wearing article 1. For this reason, if the same bonding force as the ventral coupling part 31 and the dorsal coupling part 32 is applied to the crotch coupling part 33, the absorbent pad 2 can be worn over the entire region of the ventral side, the dorsal side, and the crotch area. The absorbent pad 2 is strongly bonded to the article 1, making it difficult to remove the absorbent pad 2 from the article 1. On the other hand, in the wearing article 1, the plurality of joint parts 30 have the above-mentioned specific joint structure, so that the wearing article 1 and the absorbent pad 2 are firmly connected at the ventral joint part 31 and the dorsal joint part 32. The absorbent pad 2 can be easily removed from the wearing article 1 at the crotch joint 33 while being joined. Furthermore, the absorbent pad 2 can be easily attached to the crotch joint 33 as described below. That is, first, the absorbent pad 2 (corresponding area 41 and corresponding area 43) is bonded to the ventral side bonding part 31 and the dorsal side bonding part 32 of the wearing article 1 in the contracted state. At this time, because the wearing article 1 is contracted in the longitudinal direction L, the crotch joint portion 33 may not be joined to the appropriate position (corresponding region 43) of the absorbent pad 2. Even in that case, by vigorously stretching the wearing article 1 connected to the absorbent pad 2 at the ventral side joint part 31 and the dorsal side joint part 32 in the longitudinal direction L, the absorbent pad 2 at the crotch joint part 33 and After the bond with the wearing article 1 is once removed, the wearing article 1 is sufficiently stretched in the longitudinal direction L and the crotch joint 33 is in contact with the absorbent pad 2 (that is, the crotch joint 33 is absorbent). When the pad 2 is at an appropriate attachment position (facing the corresponding area 43), the crotch joint 33 and the absorbent pad 2 can be rejoined. As described above, according to the wearing article 1 having the specific bonding structure, the absorbent pad 2 can be easily attached and detached while suppressing the occurrence of twisting of the absorbent core in the worn state.

Hereinafter, the detailed configuration of each part of this embodiment and the effects obtained by the configuration will be described.

As described above, the ventral joint 31, the crotch joint 33 (in this embodiment, the first crotch joint 331 and the second crotch joint 332), and the back joint 32 are spaced apart from each other in the longitudinal direction L. are doing. As a result, there is no joint 30 between the ventral joint 31 and the crotch joint 33 (in this embodiment, the first crotch joint 331 disposed on the ventral side of the crotch joint 33). A non-bonding region UR1 (first non-bonding region) is formed. Further, between the back side joint part 32 and the crotch joint part 33 (in this embodiment, the second crotch joint part 332 disposed on the back side of the crotch joint part 33), there is a non-joint part 30 between which there is no joint part 30. A bonding region UR2 (second non-bonding region) is formed. The length in the longitudinal direction L of the combined region of the non-bonding region UR1 and the non-bonding region UR2 (that is, "D1 + D2") is more than half the distance D between the ventral joint portion 31 and the dorsal joint portion 32. ing. That is, the plurality of coupling parts 30 are arranged so that "D1+D2>D/2" holds true. According to the above configuration, a sufficient size (size in the longitudinal direction L) of the non-bonded regions UR1 and UR2 can be ensured between the ventral side joint part 31 and the dorsal side joint part 32. As a result, the force required to stretch the wearing article 1 in the longitudinal direction L can be reduced when attaching or detaching the absorbent pad 2 to the wearing article 1 as described above. Thereby, the absorbent pad 2 can be attached to and detached from the wearing article 1 even more easily.

As shown in FIG. 1, the ventral joint portion 31 includes a front end portion 101a, which is an end of the ventral portion 101 on the opposite side to the crotch portion 103 side, and a leg portion 13 of the ventral portion 101, in the longitudinal direction L. (that is, the ventral end of range R in FIG. 1). According to the above configuration, the ventral joint portion 31 is arranged at a position sufficiently close to the ventral end (front end 101a) (that is, close to the location where the ventral end of the absorbent pad 2 is located). be able to. As a result, the ventral end portion of the absorbent pad 2 can be appropriately positioned and fixed by the ventral joint portion 31.

The abdominal part 101 is provided along the front end part 101a, and has an elastic member 15 that contracts in the width direction W so as to tighten the wearer's waist when worn. , is arranged closer to the crotch portion 103 than the elastic member 15. That is, the ventral joint portion 31 is arranged so as not to overlap the elastic member 15. According to the above configuration, it is possible to prevent the contraction of the elastic member 15 from being inhibited by the ventral joint part 31, and also 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 becomes difficult to connect the absorbent pad 2 to the ventral side connecting portion 31).

As shown in FIG. 1, 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. As shown in FIG. 5, the width of the absorbent pad 2 is usually shorter than the width Lmin of the narrowest part 17. That is, the wearing article 1 has a larger shape than the absorbent pad 2 when viewed from the thickness direction T. Therefore, even if the width L1 of the ventral joint part 31 is extended longer than the width Lmin of the narrowest part 17, the extended part does not overlap with the absorbent pad 2 and is combined with the absorbent pad 2. It is wasted because it is not done. Furthermore, if the ventral joint portion 31 is made of a material harder than the fabric of the main body portion 10, the larger the area of the ventral joint portion 31, the more uncomfortable the wearer may feel when wearing the garment. As described above, by setting the width L1 of the ventral joint portion 31 so as to satisfy "width L1<width Lmin", the above-mentioned waste and discomfort can be suppressed.

As shown in FIG. 1, the dorsal joint portion 32 is formed by connecting the rear end portion 102a, which is the end of the dorsal side portion 102 on the opposite side to the crotch portion 103 side, and the leg opening of the dorsal side portion 102 in the longitudinal direction L. 13 (ie, the dorsal end of region R in FIG. 1). According to the above configuration, the dorsal side joint part 32 is arranged at a position sufficiently close to the dorsal side end part (rear end part 102a) (that is, at a position close to the position where the dorsal side end part of the absorbent pad 2 is arranged). can do. As a result, the back end portion of the absorbent pad 2 can be appropriately positioned and fixed by the back joint portion 32.

The back side part 102 is provided along the rear end part 102a, and has an elastic member 16 that contracts in the width direction W so as to tighten the wearer's waist when worn, and the back side joint part 32 has an elastic member 16 that contracts in the width direction W so as to tighten the wearer's waist when worn. The elastic member 16 is disposed closer to the crotch portion 103 than the elastic member 16 is. That is, the back joint portion 32 is arranged so as not to overlap the elastic member 16. According to the above configuration, it is possible to prevent the contraction of the elastic member 16 from being inhibited by the dorsal joint part 32, and also to prevent the dorsal joint part 32 from contracting in the width direction W due to the influence of the elastic member 16 (as a result, , it becomes difficult to connect the absorbent pad 2 to the back-side connecting portion 32).

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 part 17 of the main body 10. For the reason mentioned above, even if the width L2 of the dorsal joint part 32 is extended longer than the width Lmin of the narrowest part 17, the extended part does not overlap with the absorbent pad 2, and the absorbent pad 2 It is wasted because it is not combined with Further, when the back side joint part 32 is formed of a material harder than the fabric of the main body part 10, the larger the area of the back side joint part 32, the more uncomfortable the wearer feels when wearing the wearer. As described above, by setting the width L2 of the dorsal joint portion 32 so as to satisfy "width L2<width Lmin", the above-mentioned waste and discomfort can be suppressed.

The crotch joint 33 extends along the width direction W, and the horizontal width L31 of the crotch joint 33 (the length of the crotch joint 33 in the width direction W) is equal to the vertical width L32 (longitudinal length) of the crotch joint 33. The length of the crotch joint portion 33 in the direction L) is longer than the length of the crotch joint portion 33 in the direction L. According to the above configuration, the movement (twisting, etc.) of the absorbent pad 2 (the part joined to the crotch joint 33) in the width direction W can be effectively suppressed by the crotch joint 33 extending in the width direction W. . In addition, when the crotch joint 33 has a plurality of joints separated in the longitudinal direction L (in this embodiment, the first crotch joint 331 and the second crotch joint 332) as in this embodiment, the crotch joint 33 The vertical width L32 of the portion 33 is not the sum of the vertical widths of a plurality of joint parts (in this embodiment, the first crotch joint part 331 and the second crotch joint part 332), but the vertical width of each joint part. means width.

The width L31 of the crotch joint 33 is shorter than the width L1 of the ventral joint 31 and the width L2 of the back joint 32. According to the above configuration, by making the widths L1 and L2 of the ventral joint part 31 and the dorsal joint part 32, which are arranged at both ends in the longitudinal direction L, relatively long, the wearing article 1 and the absorbent pad 2 can be connected to each other. Can be strongly bonded. On the other hand, by making the width L31 of the crotch joint 33 located in the crotch region, which has a greater influence on the wearer's wearing comfort, relatively short, it is possible to reduce the discomfort that the wearer feels in the crotch region when wearing the garment. .

The width L31 of the crotch joint portion 33 is shorter than the width Lmin of the narrowest portion 17 of the main body portion 10. For the reason mentioned above, even if the width L31 of the crotch joint part 33 is extended longer than the width Lmin of the narrowest part 17, the extended part does not overlap with the absorbent pad 2 and does not overlap with the absorbent pad 2. It is wasted because it is not combined. Furthermore, if the crotch joint 33 is made of a harder material than the fabric of the main body 10, the larger the area of the crotch joint 33, the more uncomfortable the wearer may feel when wearing the garment. As described above, by setting the width L31 of the crotch joint portion 33 so as to satisfy "width L31<width Lmin", the above-mentioned waste and discomfort can be suppressed.

The distance from the first end 33a of the crotch joint 33 in the width direction W to the second end 33b of the crotch joint 33 opposite to the first end 33a in the width direction W (in this embodiment, the crotch The width L31) of the coupling portion 33 is at least ⅓ of the width Lmin of the narrowest portion 17 of the main body portion 10. According to the above configuration, by ensuring the width L31 of the crotch joint 33 is at least a certain level, movement (twisting, etc.) of the absorbent pad 2 (the part joined to the crotch joint 33) in the width direction W can be effectively prevented. It can be suppressed.

The crotch joint 33 has a first crotch joint 331 and a second crotch joint 332. The first crotch joint 331 is arranged closer to the abdominal part 101 than the second crotch joint 332 in the longitudinal direction L. According to the above configuration, by configuring the crotch joint portion 33 with a plurality of joint portions (the first crotch joint portion 331 and the second crotch joint portion 332), the absorbent pad 2 is attached to the wearer's crotch region in the wearing state. It is possible to more effectively suppress the occurrence of pinching of the absorbent core 23a and, in turn, the twisting of the absorbent core 23a.

The first crotch joint part 331 is arranged closer to the abdominal part 101 than the center position of the main body part 10 in the longitudinal direction L (that is, the center line CL). On the other hand, the second crotch joint portion 332 is arranged closer to the back side portion 102 than the center line CL. In the worn state, the wearer's urinary opening is usually located in the crotch area 103 on the ventral side of the center line CL, and the wearer's defecation opening is located in the crotch area 103 on the dorsal side of the center line CL. Therefore, according to the above configuration, by providing the first crotch joint part 331 and the second crotch joint part 332 corresponding to the urinary opening and the defecation opening, the absorbent It is possible to suppress the occurrence of twisting of the core 23a. As a result, leakage of absorption of excrement can be suitably suppressed.

The first crotch joint 331 and the second crotch joint 332 are arranged asymmetrically with respect to the center line CL. In other words, when the main body portion 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 so as not to completely overlap. More specifically, as shown in FIG. 1, in the longitudinal 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. It's also getting longer. That is, the first crotch joint 331 located on the ventral side is located farther from the center line CL than the second crotch joint 332 located on the back. Further, in the longitudinal 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 back joint 32. Normally, in the worn state, the position of the crotch 103 facing the wearer's urinary opening is farther from the center line CL than the position of the crotch 103 facing the wearer's defecation opening. In other words, the distance from the center line CL to the position corresponding to the urinary opening (position ventral to the center line CL) is from the center line CL to the position corresponding to the defecation opening (position dorsal to the central line CL). greater than the distance. Therefore, according to the above configuration, the first crotch joint 331 and the second crotch joint 332 can be brought closer to the positions corresponding to the urinary opening and the defecation opening. As a result, it is possible to effectively suppress the occurrence of twisting of the absorbent core 23a at a position closer to the urinary opening and the defecation opening, and it is possible to further effectively suppress the leakage of absorption of excrement.

The bending resistance of the first portion of the main body 10 that is composed of the part that overlaps with the crotch joint 33 and the crotch joint 33 is the same as that of the part of the main body 10 that overlaps with the ventral joint 31 and the crotch joint 31. The bending resistance of the second portion is made lower than that of the third portion, which is made up of the portion of the main body portion 10 that overlaps with the dorsal joint portion 32 and the dorsal joint portion 32. . The above-mentioned "bending resistance" is a value measured by, for example, a cantilever method. Since the first portion of the main body portion 10 is a portion facing the wearer's crotch region, it is required to be flexibly deformed in accordance with the wearer's movements when worn. According to the above configuration, by making the bending resistance of the first part lower than the bending resistance of the second part and the third part, it is possible to wear the part of the absorbent core 23a that faces the first part. It becomes possible to flexibly deform the article 1.

In the present embodiment, the bending resistance of the crotch joint 33 itself is lower than the bending resistance of the ventral joint 31 itself and the back joint 32 itself. According to the above configuration, by adjusting the bending resistance of the joint portion 30, it is easy to achieve a configuration in which the bending resistance of the first portion is lower than the bending resistance of the second portion and the bending resistance of the third portion. can be realized.

Next, the structure of the coupling portion 30 will be explained in detail. The structure of the coupling portion 30 (that is, the coupling means and method employed for coupling the absorbent pad 2 and the wearing article 1) is not limited to a specific structure. Further, the corresponding region 40 of the absorbent pad 2 corresponding to the bonding portion 30 may be provided with a structure corresponding to the structure of the bonding portion 30. Some specific examples of the coupling portion 30 are listed below.

As a first example, the coupling portion 30 may be formed of a hook material (for example, the hook portion of a hook-and-loop fastener) including a plurality of pins having claw portions at the tip portions. In this case, the corresponding region 40 may be configured by a member (for example, a so-called loop portion of a hook-and-loop fastener) to which the hook material is coupled (engaged).

As a second example, the coupling portion 30 may be formed of an adhesive structure. The adhesive structure may be constituted by, for example, an adhesive surface provided with an adhesive material such as hot melt adhesive (HMA) on the surface.

As a third example, the coupling portion 30 may be formed of a member having magnetic force (for example, a magnet). The corresponding region 40 may be provided with a magnetic material or the like that attracts the coupling portion 30 to each other by magnetic force.

As a fourth example, the coupling part 30 may be formed by one member (protrusion or depression) of the snap button. The corresponding region 40 may be provided with the other member (a recess or a convex portion) of the snap button.

As a fifth example, the coupling portion 30 may be formed of a frictional resistance member that is engaged with the wearing article 1 using frictional resistance. Examples of the frictional resistance member include a raised material configured to increase the contact area or a member having an uneven structure on its surface. Specific examples of the friction resistance member include materials made of NanoFront (registered trademark).

As a sixth example, the coupling portion 30 may be formed of a rubber material. For example, the coupling portion 30 may be formed using super strong double-sided tape, rubber anti-slip, or the like.

Next, several configuration examples for realizing the above-mentioned specific coupling structure will be described.

(First configuration example)
A specific joint structure may 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, the area of the crotch joint 33 refers to the area of the crotch joint 33 when the crotch joint 33 is composed of a plurality of joints (the first crotch joint 331 and the second crotch joint 332) as in this embodiment. , means the individual areas of the plurality of joints. That is, in this embodiment, each of the first crotch joint 331 and the second crotch joint 332 is configured to have a smaller area than the area of each of the ventral joint 31 and the dorsal joint 32. By this, a specific bonding structure is realized. According to the first configuration example, by creating a difference in area between the crotch joint 33, the ventral joint 31, and the dorsal joint 32, the specific joint structure can be realized relatively easily.

As a specific implementation method of the first configuration example, in the width direction W, the length of the crotch joint 33 (i.e., the width L31) is equal to the length of the ventral joint 31 (i.e., the width L1) and the dorsal joint. It may be shorter than the length of the portion 32 (ie, the width L2). According to the above configuration, the structure of the first configuration example can be easily realized. Furthermore, by making the width L31 of the crotch joint 33 arranged in the crotch 103 shorter than the widths L1 and L2 of the joints at both ends in the longitudinal direction L (the ventral joint 31 and the dorsal joint 32), When the wearer is wearing the wearer, the crotch joint 33 can suppress the discomfort that the wearer feels when wearing the wearer.

(Second configuration example)
When the first example is adopted as the structure of the joint part 30, the joint structure regarding at least one of the number of pins, the height, the material, and the shape of the claw part of the crotch joint part 33 is changed to the joint of the ventral joint part 31. By making the structure different from that of the dorsal coupling portion 32, a specific coupling structure may be realized. Several examples of methods for making the joint structures different between the crotch joint 33, the ventral joint 31, and the dorsal joint 32 as described above will be shown below. For example, the height of the pins of the ventral side joint part 31 and the dorsal side joint part 32 may be higher than the height of the pin of the crotch joint part 33. Further, the number of pins in the ventral side joint part 31 and the dorsal side joint part 32 may be greater than the number of pins in the crotch joint part 33. Further, depending on the combination of the number of pins, height, material, and shape of the claw portions described above, the bonding strength of the crotch bonding portion 33 may be made higher than that of the ventral bonding portion 31 and the dorsal bonding portion 32. good. According to the above configuration, by making the connection structures of the respective connection parts 30 (ventral side connection part 31, dorsal side connection part 32, and crotch connection part 33) different from each other made of hook material, it is possible to easily create a specific connection structure. realizable.

(Third configuration example)
When the second example described above is adopted as the structure of the joint part 30, for example, the coating weight, coating area, and coating area of the adhesive material are changed between the crotch joint part 33, the ventral joint part 31, and the dorsal joint part 32. A specific bonding structure may be realized by changing the working pattern or the like.

(Fourth configuration example)
When the third example is adopted as the structure of the joint part 30, for example, the magnetic force, area, etc. of the members having magnetic force may be made different between the crotch joint part 33, the ventral joint part 31, and the dorsal joint part 32. By this, a specific bonding structure may be realized.

(Fifth configuration example)
When the fourth example is adopted as the structure of the joint portion 30, for example, the number of buttons arranged, the area, etc. may be different between the crotch joint portion 33, the ventral joint portion 31, and the dorsal joint portion 32. By this, a specific bonding structure may be realized.

(Sixth configuration example)
By making the joining method of the crotch joining portion 33 (for example, the method corresponding to each of the first to sixth examples described above) different from the joining method of the ventral joining portion 31 and the joining method of the dorsal joining portion 32, Specific bonding structures may be implemented. According to the above configuration, a specific coupling structure can be easily realized by differentiating the coupling method between the crotch coupling part 33, the ventral coupling part 31, and the dorsal coupling part 32.

As a specific example of the sixth configuration example, the following configuration example is given. That is, even if the specific joint structure is realized by adopting the first example as the structure of the ventral joint part 31 and the dorsal joint part 32 and adopting the fifth example as the structure of the crotch joint part 33, good. According to the above configuration, a suitable difference in bonding strength can be created between the ventral side connecting portion 31, the dorsal side connecting portion 32, and the crotch connecting portion 33 with a relatively simple structure.

[Second embodiment]
The configuration of a wearing article 1A according to the second embodiment will be described with reference to FIGS. 7 and 8. FIG. 7 is a plan view of the wearing article 1A viewed from the skin side. FIG. 8 is a diagram schematically showing a cross-sectional structure of the wearing article 1A taken along the line VIII-VIII in FIG. 7.

The wearing article 1A is different from the wearing article 1 in that a pocket portion 18 is provided on each of the ventral side portion 101 and the back side portion 102, and the other structure is the same as the wearing article 1. In addition, the pocket part 18 may be provided only in either one of the abdominal part 101 and the dorsal part 102.

Each pocket portion 18 accommodates the end portion 2a of the absorbent pad 2 in the longitudinal direction L, and in the accommodated state in which the end portion 2a is accommodated, the outer surface of the end portion 2a (i.e., the surface 21a of the topsheet 21). It is configured to cover. In this embodiment, as an example, the pocket portion 18 has a rectangular outer shape when viewed from the thickness direction T (see FIG. 8). A fixing part 18a fixed to the inner surface 10a of the main body part 10 by embroidery or the like (see FIG. (dot hatched part) is formed. On the other hand, the inner part in the longitudinal direction L of the edge of the pocket part 18 viewed from the thickness direction T is not fixed to the inner surface 10a of the main body part 10, and forms an opening into which the absorbent pad 2 can be inserted. ing.

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 with respect to the wearing article 1. It can be carried out.

As shown in FIG. 7, the ventral pocket portion 18 covers at least a portion of the ventral coupling portion 31 when viewed from the thickness direction T, which is the direction in which the main body portion 10 and the coupling portion 30 overlap. ing. In this embodiment, the ventral pocket portion 18 covers the entire ventral joint portion 31 . That is, in the thickness direction T, the ventral pocket portion 18 overlaps the entire ventral joint portion 31. Similarly, the back pocket portion 18 covers at least a portion of the back joint portion 32 when viewed from the thickness direction T. In this embodiment, the back pocket portion 18 covers the entire back joint portion 32 . That is, in the thickness direction T, the back side pocket part 18 overlaps with the entire back side joint part 32. According to the above configuration, when the absorbent pad 2 is not attached, the ventral joint part 31 and the dorsal joint part 32, which have a relatively strong binding force (that is, have a stronger binding force than the crotch joint part 33), Unintentional coupling (sticking) to members other than the absorbent pad 2 or a part of the wearing article 1 itself can be suppressed. The above effect can also be obtained by a structure in which the pocket part 18 covers at least a part of the joint part 30 (ventral joint part 31 or dorsal joint part 32). A structure that covers the entire dorsal joint portion 32) provides even higher effects.

Here, a case will be considered in which the ventral side joint part 31 and the dorsal side joint part 32 each have a structure (the structure of the above first example) having a plurality of pins each having a claw portion at the tip. In this case, the fabric constituting the inner surface 18b (first surface) of the pocket portion 18 facing the surface 21a of the end portion 2a of the absorbent pad 2 in the stored state is made of fibers that are thicker than the protruding width of the claw portion. may be configured. In this case, the claw portion becomes difficult to engage with the inner surface 18b. Therefore, according to the above configuration, in a state where the absorbent pad 2 is not attached to the wearing article 1 (that is, a state where the inner surface 18b directly faces the ventral joint part 31 or the dorsal joint part 32), It is possible to prevent the inner surface 18b from being fixed to the ventral joint portion 31 or the dorsal joint portion 32. This makes it easier for the pocket section 18 to open when attempting to insert the absorbent pad 2 into the pocket section 18, thereby improving convenience for the wearer who is attempting to attach the absorbent pad 2 to the wearing article 1. be able to.

The fabric forming the inner surface 18b of the pocket portion 18 may be a film. Also in this case, it is possible to prevent the inner surface 18b from being fixed to the ventral side joint part 31 or the dorsal side joint part 32, and the same effect as described above can be obtained.

Furthermore, the inner surface 18b of the pocket portion 18 may have hydrophobicity. For example, the inner surface 18b may be waterproofed. According to the above configuration, when the wearer's excrement absorbed by the absorbent pad 2 leaks to the pocket part 18 via the end 2a of the absorbent pad 2, the excrement is transferred to the outer surface of the pocket part 18. 18c can be prevented from seeping out.

On the other hand, the outer surface 18c (second surface) of the pocket portion 18 that faces the wearer's skin in the worn state may have hydrophilicity. For example, the outer surface 18c may be made of a fabric (for example, a fabric made of natural fibers such as cotton or constituent fibers such as polyester) that exhibits a hydrophilic function by accumulating moisture in gaps between threads and fabrics. According to the above configuration, by imparting hydrophilicity to the outer surface 18c facing the wearer's skin, sweat absorption can be increased, and the wearing feeling of the wearing article 1 can be improved.

[Modification of second embodiment]
A modification of the second embodiment will be described with reference to FIG. 9. This modified example differs from the second embodiment in that it has a pocket part 18A instead of the pocket part 18 and a ventral joint part 131 instead of the ventral joint part 31, and the other configurations are the same as those of the second embodiment. This is similar to the second embodiment. FIG. 9(A) is a plan view of a portion where the pocket portion 18A is arranged, and FIG. 9(B) is a diagram schematically showing the cross-sectional structure along the line BB in FIG. 9(A). be. In addition, in this modification, although the part comprised by ventral side pocket part 18A and the ventral side joint part 31 is demonstrated, the part comprised by dorsal side pocket part 18A and the dorsal joint part 32 is the same. may be configured.

In this modification, the plurality of joint parts 30 further include a pocket joint part 34 provided on the inner surface 18b (first surface) of the pocket part 18A. Further, the pocket coupling portion 34 is coupled to the surface 21a (see FIG. 8) of the end portion 2a of the absorbent pad 2. That is, the pocket coupling portion 34 has a surface that can be coupled to the surface 21a of the absorbent pad 2. According to the above configuration, the wearable article 1A and the absorbent pad 2 can be bonded to each other by sandwiching the absorbent pad 2 between the pocket bonding portion 34 and the ventral bonding portion 131. Thereby, the bonding force between the wearing article 1 and the absorbent pad 2 can be increased.

Furthermore, in this modification, the pocket joint portion 34 is arranged so as not to overlap the ventral joint portion 131 in the thickness direction T. As an example, as shown in FIG. 9A, the pocket coupling portion 34 includes a plurality of (two in this modified example) portions 34a and 34b arranged so as to be spaced apart from each other in the width direction W. Further, the ventral joint portion 131 has a plurality of (three in this modified example) portions 131a, 131b, and 131c arranged so as to be spaced apart from each other in the width direction W. The portions 34a, 34b and the portions 131a, 131b, 131c are arranged alternately along the width direction W. That is, the portions 34a, 34b and the portions 131a, 131b, 131c are arranged so as not to overlap each other in the thickness direction T. When the thickness of the wearing article 1A becomes large, the stiffness becomes high in the thick part, and the flexibility is impaired. On the other hand, according to the above configuration, the wearing article 1A and the absorbent pad 2 can be firmly connected by the pocket joining part 34 and the ventral joining part 131, and the pocket joining part 34 and the ventral joining part 131 can be connected vertically. By arranging the bonding parts 30 so as not to overlap with each other, it is possible to suppress an increase in the thickness of the wearing article 1A due to the overlapping of the joint parts 30, and to ensure the flexibility of the wearing article 1A.

For example, each coupling portion 30 may be composed of a plurality of parts separated in the width direction W. Further, in the above embodiment, the crotch joint 33 is composed of two joints 30 (the first crotch joint 331 and the second crotch joint 332), but for example, one crotch joint 33 is arranged along the center line CL. It may be configured by two coupling parts 30. Further, in the above embodiment, the lengths in the longitudinal direction L of each of the coupling parts 30 are the same, but the lengths in the longitudinal direction L of the coupling parts 30 may be different between the coupling parts 30.

In the above embodiment, the wearing article 1 is a tape-type cloth underwear, but the wearing article 1 may be a pants-type cloth underwear.

In the embodiment described above, the surface 22a of the back sheet 22 of the absorbent pad 2 is provided with a corresponding region 40 corresponding to each bonding portion 30, but the surface 22a is formed of a material that can be bonded to each bonding portion 30. If so, the corresponding area 40 may be omitted.

In addition, in order to obtain the effect of the specific joint structure of the plurality of joint parts 30, the ventral joint part 31, the crotch joint part 33, and the dorsal joint part 32 must be connected continuously (that is, spaced apart) along the longitudinal direction L. may be provided (without). That is, in order to obtain the above effect, the configuration in which the ventral side joint part 31, the crotch joint part 33, and the back side joint part 32 are arranged apart from each other along the longitudinal direction L is not essential.
