DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments.

[0026] <Basic composition of underwear 1> Fig. 1 is a front view of the underwear 1 of this embodiment, and Fig. 2 is a front view of the underwear 1 of this embodiment turned inside out. As shown in Figs. 1 and 2, the underwear 1 of this invention comprises a placket 2 provided at the front center so as to cover a man's private parts, a body 11 connected to both side parts 22, 23 and a lower part 24 of the placket 2 to cover the waist area, and a waist elastic 12 connected to the upper part 21 of the placket 2 and the upper end of the body 11. Note that, although the body 11 of this embodiment is made of a single piece of fabric, the body 11 may be formed by joining multiple pieces of fabric together into one piece.

[0027] The placket 2 comprises, in the order from the front side to the back side of the underwear 1, an upper placket 3, a lower placket 4, an inner fabric 5, and a lining 6. Of these, the upper placket 3 and the lower placket 4 constitute the placket main body 20. In this specification, the "front side" means the side that faces the outside of the underwear 1 when worn by a user, and the "back side" means the side of the underwear 1 that faces the body of the user. Note that the "front side" and "back side" mentioned here do not necessarily coincide with the front and back sides of the fabrics themselves that constitute each member.

[0028] The upper placket 3 has a portion on its side (side edge 23 in FIG. 1) that is not sewn to the body 11. The area of ​​this side edge 23 of the upper placket 3 that is not sewn to the body 11 forms an opening 25 through which the male private parts can be inserted and removed. The lower placket 4 has a portion on its side opposite to the side edge 23 of the upper placket 3 (side edge 22 in FIG. 2) that is not sewn to the body 11. The area of ​​this side edge 22 of the lower placket 4 that is not sewn to the body 11 forms an opening 26 through which the male private parts can be inserted and removed. These openings 25 and 26 are connected.

[0029] As shown in Figs. 1 and 2, the opening 26 on the lower placket 4 side is formed longer in the vertical direction in terms of the opening dimension than the opening 25 on the upper placket 3 side. That is, in the opening 25, the upper end 25a and the lower end 25b of the opening are both located halfway along the side edge 23 of the placket 2, while in the opening 26, the lower end 26b of the opening reaches the lower edge 24 of the placket 2. In this way, by making the lower opening of the opening 26 wider, it becomes easier to put in and take out the male private parts, and it is possible to suppress the return of wetness or seepage of urine from the side edge 22 side to the body 11 side. Here, "return of wetness" means that urine once absorbed by the fabric of the underwear 1 seeps out to the outside of the underwear 1 through the seams of the sewn parts.

[0030] <Components of the front plate 2> 3 shows the fabrics of the placket 2 before cutting and sewing, arranged in the order of arrangement from the front side (upper right in the drawing) to the back side (lower left in the drawing) of the underwear 1. As shown in the drawing, the placket 2 of this embodiment comprises an upper placket 3, a lower placket 4, a middle fabric 5, and a lining 6, as seen from the front side of the underwear 1. It further comprises water-repellent fabrics 71, 81 sewn along the respective recessed sides 4d, 5d, 6d of the lower placket 4, the middle fabric 5, and the lining 6, water-repellent fabrics 72, 73, 74 sewn along the upper side 6a, the side side 6b, and the lower side 6c of the lining 6, and a binder B sewn along the recessed side 3c of the upper placket 3. Each part will be described in detail below.

[0031] As shown in FIG. 3, the upper placket 3 is formed in a generally vertically elongated quadrangle with the lower side 3e shorter than the upper side 3a. One side of the quadrangle is recessed to form a recessed side 3c. Specifically, the side opposite the side 3f has a recessed side 3c that curves inward between the side 3b formed at the upper part and the side 3d formed at the lower part. The recessed side 3c of the upper placket 3 is not sewn to the body 11, and an opening 25 of the placket 2 is formed between the recessed side 3c and the lower placket 4. The upper placket 3 of this embodiment is formed from the same fabric as the body 11.

[0032] The lower placket 4 is formed in a vertically long, approximately rectangular shape with the lower side 4c shorter than the upper side 4a. One side of the rectangle is recessed to form a concave side 4d. Specifically, the side opposite the side 4b has a side 4e formed at the upper part and a concave side 4d formed at the lower part, which curves inward. The lower placket 4 is not sewn to the body 11 at the concave side 4d, and an opening 26 of the placket 2 is formed between the concave side 4d and the upper placket 3. The concave side 4d of the lower placket 4 is formed on the side opposite to the concave side 3c of the upper placket 3. The lower placket 4 of this embodiment is formed from the same fabric as the body 11.

[0033] The intermediate fabric 5 is formed in substantially the same shape as the lower placket 4. That is, it is formed in a substantially vertically elongated quadrilateral shape in which the lower side 5c is shorter than the upper side 5a. Specifically, in the side portion opposite the side portion 5b, a side portion 5e is formed in the upper portion, and a concave side portion 5d is formed in the lower portion, which is curved inward. The intermediate fabric 5 is not sewn to the body 11 at the concave side portion 5d. The intermediate fabric 5 of this embodiment is formed of a pile fabric such as cotton having water absorption. As the material of the intermediate fabric 5, in addition to natural fibers such as cotton, water-absorbent fibers such as regenerated cellulose fibers such as cupra and viscose rayon, and synthetic fibers such as water-absorbent polyester can be used. In addition, as the knitted fabric, a rib knit or smooth knit, or even a weft knitted fabric such as plain knit, or a warp knitted fabric such as raschel knit can be suitably used.

[0034] Furthermore, a waterproof layer 52 is provided on the outer surface 51 (see Figs. 4 and 5) of the inner fabric 5 of this embodiment, i.e., the side facing the lower placket 4. A polyurethane sheet that is waterproof and moisture permeable can be suitably used as the waterproof layer 52. Here, "waterproof" refers to the property of a fabric that does not allow liquid water to pass through, and "moisture permeable" refers to the property of a fabric that allows gaseous water vapor to pass through.

[0035] The lining 6 is formed so as to have substantially the same shape as the lower placket 4 and the middle fabric 5 when the water-repellent fabrics 72, 73, and 74 are sewn to each side. That is, the lining 6 is formed to be slightly smaller overall than the lower placket 4 and the middle fabric 5. The lining 6 is formed to be substantially rectangular with a lower side 6c shorter than the upper side 6a. Specifically, the lining 6 has a side part 6e formed at the upper part of the side part facing the side part 6b, and a concave part 6d formed at the lower part thereof and curved inward. The lining 6 is not sewn to the body 11 at the concave part 6d. The lining 6 is preferably formed of a material that has excellent moisture absorption and diffusion properties and has a function of preventing wetness from returning. That is, the lining 6 does not have the water retention properties of the middle fabric 5, but it can quickly absorb moisture and diffuse it over a wider area of ​​the fabric.

[0036] The water-repellent fabrics 72, 73, 74 are sewn along the upper edge 6a, the side edge 6b, and the lower edge 6c of the lining 6, respectively. The water-repellent fabrics 72, 73, 74 are formed in strips of a predetermined width along each edge of the lining 6 to which they are sewn. Each of the water-repellent fabrics 72, 73, 74 is folded along the longitudinal direction and sewn in a state in which each end of the lining 6 is sandwiched from the front and back.

[0037] The water-repellent fabrics 71 and 81 are sewn along the recessed sides 4d, 5d, and 6d of the lower placket 4, the inner fabric 5, and the lining 6. The water-repellent fabrics 71 and 81 are formed in a belt shape of a predetermined width along the recessed sides 4d, 5d, and 6d to which they are sewn. The water-repellent fabric 81 is formed to be longer in the width direction than the water-repellent fabric 71. These water-repellent fabrics 71 and 81 are both folded along the longitudinal direction and sewn in a state in which the ends of the recessed sides 4d, 5d, and 6d are sandwiched from the front and back.

[0038] For the water-repellent fabrics 71, 72, 73, and 74, a water-repellent fabric whose surface is coated with silicon or fluorine can be preferably used. As such a water-repellent fabric, a water-repellent waterproof fabric having a waterproof function is preferable. For the water-repellent fabric 81, a synthetic fabric that has been subjected to a water-repellent treatment can be used. As the knitted fabric, a milling knit, a smooth knit, a weft knit such as a plain knit, or a warp knit such as a raschel knit can be used. In particular, polyester ester smooth, which has a small surface unevenness and is smooth and pleasant to the touch, can be preferably used. Among such ester smooth fabrics, a densely knitted cloth or a densely woven fabric with a high density is used to prevent moisture and dirt from passing through, and durability can be maintained by adding a water-repellent function.

[0039] <Front 2> Fig. 4 is a IV-IV cross section of Fig. 1, Fig. 5 is a VV cross section of the opening 25 portion of Fig. 1, Fig. 6 is an enlarged cross section of Fig. 5, and Fig. 7 is a VII-VII cross section of Fig. 1. In Figs. 4 and 5, the upper side of the body 11 represents the back side of the underwear 1 (the side facing the user's body), and the lower side represents the front side (outside) of the underwear 1, and in Fig. 7, the left side of the body 11 or the waistband 12 represents the back side of the underwear 1 (the side facing the user's body), and the right side represents the front side (outside) of the underwear 1.

[0040] First, a method of sewing the placket 2 and the body 11 above the opening 25 will be described. As shown in Fig. 4, side edges 3b, 4b, 5b, and 6b of the upper placket 3, the lower placket 4, the middle fabric 5, and the lining 6 are sewn near the end 111 on the back side of the body 11 (sewn part 101). Furthermore, opposite side edges 3f, 4e, 5e, and 6e of the upper placket 3, the lower placket 4, the middle fabric 5, and the lining 6 are sewn near the end 112 on the back side of the body 11 (sewn part 102).

[0041] The sewn portion 101 on the end portion 111 side of the body 11 will be described. The sewn portion 101 is a portion where each component member constituting the placket 2 is sewn to the body 11 at the side portion 23 of the placket 2 (see FIG. 1). In the sewn portion 101, the lining 6, the upper placket 3, the lower placket 4, and the inner fabric 5 are sewn in this order when viewed from the body 11. Of these side portions, the upper placket 3, the lower placket 4, and the inner fabric 5 are sewn along the end portion 111 on the back side of the body 11.

[0042] On the other hand, the water-repellent fabric 73 is folded in half along the longitudinal direction and sewn to the lining 6 so as to sandwich the side edge portion 6b from the front and back, and the water-repellent fabric 73 is sewn at the sewing portion 101. The water-repellent fabric 73 is arranged so that the folded portion and the surrounding area do not overlap with the lining 6 when sewn to the lining 6. In other words, the central portion of the water-repellent fabric 73 in the width direction does not overlap with the lining 6 and protrudes from the side edge portion 6b of the lining 6. In this way, the portion of the water-repellent fabric 73 that does not overlap with the lining 6 is sewn to the body 11, so that the side edge portion 6b of the lining 6 is not directly sewn to the body 11, but is indirectly fixed to the body 11 via the water-repellent fabric 73.

[0043] Here, the upper placket 3, the lower placket 4, and the intermediate fabric 5 are sewn in a general direction of a placket (hereinafter referred to as "first direction"). More specifically, the upper placket 3, the lower placket 4, and the intermediate fabric 5 are sewn so as to extend from the sewing part 101 toward the end 112 side of the body 11. On the other hand, the lining 6 is sewn in the opposite direction (hereinafter referred to as "second direction") so as to overlap with the body 11. More specifically, the lining 6 is sewn so as to extend from the sewing part 101 toward the opposite side to the end 112 side of the body 11. In other words, the lining 6 is sewn so as to extend toward the opposite side to the upper placket 3, the lower placket 4, and the intermediate fabric 5.

[0044] Here, the lining 6 is provided so as to wrap around the upper placket 3, the lower placket 4 and the middle fabric 5. More specifically, the lining 6 is sewn and folded so as to extend in the opposite direction to the upper placket 3, the lower placket 4 and the middle fabric 5, and is provided so as to wrap around the ends of the upper placket 3, the lower placket 4 and the middle fabric 5. Here, as described above, the ends of the lining 6 are not directly sewn at the sewing part 101, but are indirectly sewn by the water-repellent fabric 73. This can prevent urine from returning or seeping out from the lining 6 to the body 11 through the sewing part 101. In addition, the upper placket 3, the lower placket 4 and the middle fabric 5 are sewn with the water-repellent fabric 73 sandwiched between them and the body 11. This can prevent urine from returning or seeping out from the middle fabric 5 through the seams of the sewing part 101.

[0045] The sewn portion 102 on the end portion 112 side of the body 11 will now be described. As shown in Fig. 4, the fabrics are sewn together in the order of upper placket 3, lower placket 4, middle fabric 5, and lining 6, when viewed from the body 11. The side edges of each of these fabrics are sewn together along the end portion 112 on the back side of the body 11.

[0046] Next, a method of sewing the placket 2 and the body 11 at the portion where the openings 25, 26 are provided will be described. As shown in FIG. 5, the upper placket 3 is not sewn to the body 11 at the sewing portion 101. To explain further, the recessed side portion 3c of the upper placket 3 is not sewn to the body 11 and forms a free end. A binder B is provided in this recessed side portion 3c so as to sandwich the recessed side portion 3c from the front and back. Furthermore, the upper placket 3 and the lower placket 4 are not sewn to each other and are provided so as to be separable from each other. Then, the opening 25 of the upper placket 3 and the opening 26 of the lower placket 4 are formed.

[0047] As shown in Fig. 5, in the portion where the opening 26 of the lower placket 4 is provided, the respective recessed sides 4d, 5d, 6d of the lower placket 4, the intermediate fabric 5, and the lining 6 are not sewn to the body 11, and form free ends. Water-repellent fabrics 71 and 81 are sewn to the respective recessed sides 4d, 5d, 6d on the free end sides of the lower placket 4, the intermediate fabric 5, and the lining 6 so as to sandwich them from the front and back in an overlapping state (sewn portion 201). Hereinafter, the water-repellent fabrics 71 and 81 will be described in detail with reference to Fig. 6.

[0048] The water-repellent fabric 71 is folded in two along the longitudinal direction so as to sandwich the respective recessed side portions 4d, 5d, and 6d of the lower placket 4, the middle fabric 5, and the lining 6, and the side portion 81d of the water-repellent fabric 81 from the front and back, and is sewn in such a state. Note that, since Figs. 5 and 6 are schematic cross-sectional views, the water-repellent fabric 71 is illustrated in an approximately U-shape, but in reality, it is folded in two. And, by folding in two in this way, two pieces 711 and 712 are formed with the folded portion as a boundary. Of these, the piece 711 is disposed on the lining 6 side, and the piece 712 is disposed on the lower placket 4 side. More specifically, the piece 712 of the water-repellent fabric 71 is disposed so as to cover a part of the area along the recessed side portion 4d of the lower placket 4. Also, the piece 711 of the water-repellent fabric 71 is disposed so as to cover a part of the area along the side portion 81d of the waterproof fabric 81.

[0049] In this embodiment, the piece 711 and the piece 712 are formed to have different widthwise lengths. Specifically, in this embodiment, the ratio of the widthwise length L1 of the piece 711 to the widthwise length L2 of the piece 712 is formed to be approximately 1:2. Note that the ratio of the widthwise lengths of the piece 711 and the piece 712 is not limited to this, and may be 2:3 or 3:4. In this way, the widthwise length of the piece 712 is formed to be longer than the widthwise length of the piece 711, which makes it easier to perform the sewing work described below.

[0050] Water-repellent fabric 81 is folded in two along the longitudinal direction and is provided so as to cover the outside of water-repellent fabric 71 along the water-repellent fabric 71. By folding water-repellent fabric 81 in two, two pieces 811, 812 are formed with the folded portion as the boundary. Of these, piece 811 is disposed along piece 711 of water-repellent fabric 71. Furthermore, piece 812 is disposed along piece 712 of water-repellent fabric 71. In other words, piece 811 is disposed so as to cover piece 711, and piece 812 is disposed so as to cover piece 712.

[0051] Furthermore, the piece 811 is provided with a folded piece 813 that is folded back at a predetermined width along the side edge portion 81d. The folded piece 813 is provided so as to sandwich the side edge portion 71d of the water-repellent fabric 71 inside the folded piece. In other words, the water-repellent fabric 81 is overlapped along the water-repellent fabric 71, and the folded piece 813 is folded back so as to roll the side edge portion 71d of the water-repellent fabric 71 inward. As a result, the folded piece 813 is disposed in a state of being sandwiched between the piece 711 and the lining 6.

[0052] The water-repellent fabric 81 is sewn to the water-repellent fabric 71, the lining 6, the middle fabric 5, and the lower placket 4 at the folded-back piece 813. Furthermore, the side edge portion 81b opposite to the side edge portion 81d where the folded-back piece 813 is provided is sewn along the side edge portion 71b of the water-repellent fabric 71. In this manner, the recessed edges 4d, 5d, and 6d of the lower placket 4, the middle fabric 5, and the lining 6 are covered by the water-repellent fabric 71, so that seepage from these recessed edges 4d, 5d, and 6d can be suppressed. Furthermore, since the water-repellent fabric 81 is fixed using the sewn portion 201 and the sewn portion 201 is covered by the water-repellent fabric 81, even if seepage occurs from the sewn portion 201, the return of wetness to the body 11 can be suppressed.

[0053] Next, with reference to FIG. 7, a method of attaching the upper side portion 6a and the lower side portion 6c of the lining 6 to the body 11 will be described. As shown in FIG. 7, the water-repellent fabrics 72, 74 are sewn to the upper side portion 6a and the lower side portion 6c of the lining 6 so as to sandwich the upper side portion 6a and the lower side portion 6c from the front and back. The water-repellent fabrics 72, 74 are folded in two along the longitudinal direction, and further include fold-back pieces 721, 741 folded back at a predetermined width along the side portions 72a, 74a. These fold-back pieces 721, 741 are provided by folding back the water-repellent fabrics 72, 74 folded in two further inward. As a result, the side portions 72a, 74a are covered by the water-repellent fabrics 72, 74. These fold-back pieces 721, 741 are arranged so as to overlap the back surface 61 of the lining 6. That is, the fold-back pieces 721, 741 are disposed on the side of the lining 6 that faces the user's body.

[0054] Furthermore, the water-repellent fabrics 72, 74 are arranged such that the folded portions and the surrounding areas do not overlap with the lining 6 when sewn to the lining 6. In other words, the central portions of the water-repellent fabrics 72, 74 in the width direction do not overlap with the lining 6 and protrude from the upper side portion 6a and the lower side portion 6c of the lining 6.

[0055] The water-repellent fabrics 72, 74 are sewn to the lining 6 together with the folded pieces 721, 741. The water-repellent fabrics 72, 74 do not overlap the lining 6, but are sewn to the waist rubber 12 and the body 11 at the portions protruding from the lining 6. With this configuration, the lining 6 is not directly sewn to the waist rubber 12 and the body 11 at its upper side portion 6a and lower side portion 6c, but is indirectly sewn to them via the water-repellent fabrics 72, 74. This makes it possible to prevent water from returning or seeping out from the lining 6 to the waist rubber 12 and the body 11.

A series of manufacturing steps for the placket 2 will be described below with reference to FIGS. 8 to 17. It is assumed here that a binder B has been provided in advance along the concave side portion 3c of the upper front placket 3 by a well-known technique.

[0057] The first step in Fig. 8 is a step of temporarily fastening the fabrics of the placket 3, the lower placket 4, and the inner fabric 5 together. Specifically, when viewed from the body 11 side, the fabrics are layered in the order of the upper placket 3, the lower placket 4, and the inner fabric 5, and temporarily fastened with water-repellent thread along the side edges 3b and 3d of the upper placket 3, the side edge 4b ​​of the lower placket 4, and the side edge 5b of the inner fabric 5 (sewing part 202). Note that "temporarily fastening" here means temporarily sewing the fabrics together to fix them before the actual sewing.

[0058] The second step in FIG. 9 is a step of attaching the water-repellent fabric 72 and the water-repellent fabric 74 to the upper side portion 6a and the lower side portion 6c of the lining 6, respectively. First, the water-repellent fabrics 72 and 74 are folded in half along the longitudinal direction. Then, the water-repellent fabrics 72 and 74 are folded back at a predetermined width along one side portion 72a and 74a to form folded-back pieces 721 and 741. The folded-back pieces 721 and 741 are folded back in such a way that they are further folded inside the folded-back water-repellent fabrics 72 and 74. In other words, the folded-back pieces 721 and 741 are arranged so as to overlap the lining 6. The folded-back water-repellent fabrics 72 and 74 sandwich the upper side portion 6a and the lower side portion 6c of the lining 6 from the front and back, and are sewn at the positions of the folded-back pieces 721 and 741 (sewn parts 203 and 204). At this time, the folded portion and the surrounding area are arranged so as not to overlap with the lining 6.

[0059] The third step in FIG. 10 is a step of attaching the water-repellent fabric 73 to the side edge portion 6b of the lining 6. In this step, the lining 6 is turned inside out from the state in the second step, and further placed so that the vertical positional relationship is reversed, from the viewpoint of work efficiency. In this step, the water-repellent fabric 73 is folded in two in advance along the longitudinal direction. Then, the side edge portion 6b of the lining 6 is sandwiched from the front and back and sewn (sewn part 205). At this time, the folded part and the surrounding area are arranged so as not to overlap with the lining 6. In this way, by sewing the water-repellent fabric 73 after the water-repellent fabrics 72 and 74, it becomes easier to fold the lining 6 toward the middle fabric 5 in the sixth step described later.

[0060] The fourth step in Fig. 11 is a step of temporarily fixing the lining 6 to the body 11. As shown in Figs. 11(a) and (b), the water-repellent fabric 73 sewn to the side edge 6b (see Fig. 11(b)) of the lining 6 is placed along the end 111 of the body 11. At this time, the lining 6 is placed in a direction (second direction) in which it overlaps with the body 11. In this state, the portion of the water-repellent fabric 73 that does not overlap with the lining 6 is sewn to the body 11 (sewn portion 206).

[0061] The fifth step in Fig. 12 is a step of attaching the fabric temporarily fixed in the first step in Fig. 8 to the body 11. First, the side edges 3b, 3d (not shown) of the upper placket 3, the side edge 4b ​​of the lower placket 4, and the side edge 5b of the inner fabric 5 are arranged to overlap the side edge 6b of the lining 6 and the end 111 of the body 11. At this time, the lower placket 4 and the inner fabric 5 are arranged in a direction (first direction) that does not overlap with the body 11. Then, the overlapping portions of the body 11 and the other fabrics are sewn with a water-repellent thread by a flat seam (sewing portion 101). By sewing with a flat seam, there is no discomfort to the skin due to the seams, and the wearing comfort is not impaired.

[0062] The sixth step in Fig. 13 is a step of folding back the lining 6 towards the inner fabric 5. As shown in Figs. 13(a) and (b), the lining 6 is folded back in the first direction so as to overlap the inner fabric 5. In this state, the side edge 4b ​​of the lower placket 4 and the side edge 5b of the inner fabric are covered by the lining 6. Furthermore, the sewn portion 101 is also covered by the lining 6.

[0063] The seventh step in Fig. 14 is a step of attaching the water-repellent fabric 81 to the placket 2. The water-repellent fabric 81 is placed along the concave side portion 6d of the lining 6 in a flat state before being folded in two along the longitudinal direction. Then, the side portion 81d of the water-repellent fabric 81 is temporarily fixed together with the concave side portion 6d of the lining 6, the concave side portion 5d of the middle fabric 5, and the concave side portion 4d of the lower placket 4 (sewn portion 207).

[0064] The eighth step in Fig. 15 is a step of attaching the water-repellent fabric 71 to the placket 2. The water-repellent fabric 71 is folded in two and arranged so that the piece 711 is along the water-repellent fabric 81 and the piece 712 is along the lower placket 4. That is, the piece 711 and the piece 712 are arranged to sandwich the side edge 81d of the water-repellent fabric 81, the recessed edge 6d of the lining 6, the recessed edge 5d of the intermediate fabric 5, and the recessed edge 4d of the lower placket 4 from the front and back. In this state, the side edge 81d of the water-repellent fabric 81, the recessed edge 6d of the lining 6, the recessed edge 5d of the intermediate fabric 5, and the recessed edge 4d of the lower placket 4 are stitched along the side edge 71d of the water-repellent fabric 71 (sewn part 201). As described above, the water-repellent fabric 71 is formed so that the widthwise length of the piece 712 is longer than the widthwise length of the piece 711. This makes it easier to carry out the next ninth step.

[0065] The ninth step in FIG. 16 is a step of folding back the water-repellent fabric 81 and sewing it to the side edge portion 71b of the water-repellent fabric 71. The water-repellent fabric 81 is folded back so as to cover the water-repellent fabric 71. First, the water-repellent fabric 81 is folded back in the opposite direction starting from the sewn portion 201, forming a folded back piece 813. Then, the water-repellent fabric 81 is folded back along the water-repellent fabric 71, so that the water-repellent fabric 71 and the sewn portion 208 are covered by the water-repellent fabric 81. The side edge portion 81b of the water-repellent fabric 81 folded back in this manner is substantially aligned with the side edge portion 71b of the water-repellent fabric 71, or the side edge portion 81b of the water-repellent fabric 81 extends toward the sewn portion 101 side and protrudes beyond the side edge portion 71b of the water-repellent fabric 71. The side edge portion 81b of the water-repellent fabric 81 and the side edge portion 71b of the water-repellent fabric 71 are sewn together (sewn portion 208). Here, the ends of the side edge portion 81b and the side edge portion 71b are preferably sewn together by overlock processing. If the side edge portion 81b of the water-repellent fabric 81 protrudes beyond the side edge portion 71b of the water-repellent fabric 71, the excess portion is cut off during the overlock processing.

[0066] The tenth step in FIG. 17 is a step of sewing the side edge portion 22 side of the placket 2 to the body 11. As shown in FIG. 17(b), the side edge portion 6e of the lining 6, the side edge portion 5e of the middle fabric 5, the side edge portion 4e of the lower placket 4, and the side edge portion 3f of the upper placket 3 are sewn along the end portion 112 of the body 11 (sewn portion 102). In the same manner, each fabric is sewn along the folded portion 722 of the water-repellent fabric 72 at the sewing portion 103, and further, each fabric is sewn along the folded portion 742 of the water-repellent fabric 74 at the sewing portion 104. The sewing portions 102, 103, and 104 are sewn by a flat seam with water-repellent thread. Such flat seam sewing does not cause discomfort in the seams and does not impair the wearing comfort.

[0067] The thread used in the sewing in each step described above is not particularly limited, but a thread that has been treated to be water repellent is preferably used, and polypropylene thread, polyester water repellent thread, acrylic water repellent thread, nylon water repellent thread, acetate water repellent thread, and ethylene vinyl alcohol water repellent thread are preferably used.

[0068] <Action and effect> Next, the effect of the underwear 1 of this embodiment will be described with reference to Figure 5 again. With the underwear 1 of this embodiment, when urine remaining from the urethra after urination drips out, it is quickly absorbed by the pile fabric of the middle fabric 5 via the lining 7. The lining 6 has excellent absorption and diffusion properties and also has a function of preventing wetness returning, so the skin side can maintain a dry and comfortable fit.

[0069] In the portion where the opening 26 of the lower placket 4 is provided, the respective recessed sides 4d, 5d, and 6d of the lower placket 4, the intermediate fabric 5, and the lining 6 are doubly covered at their ends with the water-repellent fabric 71 and the water-repellent fabric 81. Furthermore, the sewn portion 201 that sews the respective fabrics is covered with the water-repellent fabric 81. This makes it possible to suppress backwetting and seepage from the respective recessed sides 4d, 5d, and 6d that form the opening 26.

[0070] In addition, the side edge portion 6b of the lining 6 on the side of the sewn portion 101 is not directly sewn to the body 11, but is indirectly sewn to the body 11 via the water-repellent fabric 73. The water-repellent fabric 73 is also interposed between the upper placket 3, the lower placket 4, and the middle fabric 5 and the body 11. This makes it possible to prevent urine from returning or seeping out from the seams of the sewn portion 101 to the body 11. Furthermore, the upper edge portion 6a and the lower edge portion 6c of the lining 6 are not directly sewn to the waist rubber 12 and the body 11, but are indirectly sewn to the water-repellent fabrics 72, 74. This makes it possible to prevent urine from returning or seeping out from the lining 6 to the waist rubber 12 and the body 11.

[0071] Furthermore, since the inner fabric 5 has a waterproof layer 52 applied to its surface 51 on the side of the lower front placket 4, absorbed urine is prevented from seeping out to the lower front placket 4.

[0072] In the upper part of the openings 25, 26 (area A in Fig. 2), the side edge 5e of the inner fabric 5 is sewn to the body 11 via the lower placket 4 and the upper placket 3 by a flat seam (see Fig. 4), but since there is a low possibility of urine from urinary leakage adhering to the upper part of the opening 25 of the placket 2, there is also little risk of urine seeping out from the inner fabric 5 to the outer side. In addition, the position of the sewn parts visible from the outside is the same as that of conventional underwear, so there is no risk of impairing the appearance or wearing comfort.

[0073] <Variation 1> 18 is an exploded view of each component of the placket 200 in a modified example of the underwear 1 according to the present invention. The difference from the first embodiment described above is that the shape of the lower placket 401 is formed so that its length in the width direction is shorter than that of the middle fabric 501 and the lining 601. Note that, since the other components are the same as those in the first embodiment already described, their description may be omitted.

[0074] Fig. 19 is a cross-sectional view of Modification 1 of the underwear 1. The cross-sectional view corresponds to the VV cross-sectional view of Fig. 1 in the above embodiment. As shown in Fig. 19, the placket 200 according to Modification 1 is provided with a placket main body 210 (upper placket 301, lower placket 401), an intermediate fabric 501, and a lining 601 stacked in this order when viewed from the body 11.

[0075] In the placket 200 of the first modification, the water-repellent fabric 701 and the water-repellent fabric 801 are provided so as to sandwich the respective recessed side portions 501d, 601d of the middle fabric 501 and the lining 601 from the front and back. Meanwhile, the recessed side portion 401d of the lower placket 401 is sewn to the side portion 801b of the water-repellent fabric 801. The water-repellent fabric 801 has a folded-back piece 8011 folded back at a predetermined width along the side portion 801d. In addition, the side portion 801b opposite to the side portion 801d on which the folded-back piece 8011 is formed has a folded-back piece 8012 folded back at a predetermined width along the side portion 801b.

[0076] The water-repellent fabric 701 includes a folded piece 7011 formed by folding back a predetermined width along the side edge portion 701d. The folded piece 8011 of the water-repellent fabric 801 is overlapped and sewn so as to be sandwiched between the folded piece 7011 of the water-repellent fabric 701 and the lining 601. In other words, the folded piece 8011 of the water-repellent fabric 801 is sewn together with the concave side portion 501d of the intermediate fabric 501 and the concave side portion 601d of the lining 601 in a state of being sandwiched between the water-repellent fabric 701.

[0077] In addition, the folded piece 8012 of the water-repellent fabric 801 is disposed so as to face the lower placket 401. The folded piece 8012 of the water-repellent fabric 801 is sewn along the concave side portion 401d of the lower placket 401. As described above, in the placket 200 of the first modified example, the lower placket 401 is not sewn to the intermediate fabric 501 on the concave side portion 401d side, but is sewn with the water-repellent fabric 801 in between, so that it is possible to suppress backwetting or seeping out from the sewn portion 2011 to the lower placket 401.

[0078] <Variation 2> Fig. 20 is a cross-sectional view of Modification 2 of the underwear 1. The cross-sectional view corresponds to the VV cross-sectional view of Fig. 1 in the above embodiment. As shown in Fig. 20, the placket 220 of Modification 2 is provided with the placket main body 212 (upper placket 302, lower placket 402), the intermediate fabric 502, and the lining 602 stacked in this order when viewed from the body 11.

[0079] The placket 220 of the second modified example is similar to that of the first embodiment in that the water-repellent fabric 702 and the water-repellent fabric 802 are sewn to sandwich the respective concave edge portions 402d, 502d and 602d of the lower placket 402, the middle fabric 502 and the lining 602 from the front and back (sewn portion 2021). Meanwhile, water-repellent fabric 713 is folded along the longitudinal direction and sewn to sandwich side edge portion 602b of lining 602 from the front and back. Side edge portion 602b of lining 602 is not directly sewn to body 11, but is indirectly fixed to body 11 via water-repellent fabric 713.

[0080] The water-repellent fabric 713 of the second modification is formed to be wider in the width direction than the water-repellent fabric 73 of the first embodiment and the water-repellent fabric 703 of the first modification. The water-repellent fabric 703 is folded in two at the folded part 713c along the longitudinal direction and sewn to the body 11 along the folded part 713c (sewing part 101). Here, the water-repellent fabric 713 is folded back so as to extend in the same direction as the lower placket 402 and the middle fabric 502 as seen from the sewing part 101, so as to wrap around the ends of the lower placket 402 and the middle fabric 502. As shown in FIG. 20, in the portion where the opening 252 is provided, the side part 302c of the upper placket 302 is not sewn to the sewing part 101. On the other hand, in the portion where the opening 252 is not provided, the side edges (not shown) located at the upper and lower parts of the upper placket 302 are sewn at the sewing portion 101, and the ends are wrapped around the water-repellent fabric 713.

[0081] In this way, the water-repellent fabric 713 is provided so as to wrap around the ends of the upper placket 302, the lower placket 402, and the intermediate fabric 502, and further, parts of the side edges 713b, 713d are provided so as to be located on the front side of the intermediate fabric 502. In other words, a part of the side edge 502b side of the intermediate fabric 502 is covered by the water-repellent fabric 713. In other words, a part of the intermediate fabric 502 is exposed to the skin side of the user.

[0082] The water-repellent fabric 713 is folded in two at the two-fold portion 713c, and further includes a fold-back piece 7131 that is folded back at a predetermined width along the side portion 713d. The fold-back piece 7131 is provided by folding back the water-repellent fabric 713 that is folded in two toward the inside. As a result, the side portion 713d is covered with the water-repellent fabric 713. These fold-back pieces 7131 are arranged to overlap the back surface 6021 of the lining 602. In other words, the fold-back piece 7131 is arranged on the side of the user's body with respect to the lining 602. The water-repellent fabric 713 is sewn along the side portions 713b and 713d with the fold-back piece 7131 and the lining 602 sandwiched therebetween (sewn portion 2023).

[0083] As described above, in the second modification, the exposed area of ​​the water-repellent fabric 713 is relatively narrower than in the first embodiment. In particular, the water-repellent fabric 713 is less likely to come into contact with the body 11 at the seam 101. This prevents seepage even if the inner fabric 502 moves with the movement of the body, and eases anxiety. It also reduces discomfort caused by the shifting of the inner fabric 502. Furthermore, since the seam 101 is covered with the water-repellent fabric 713, seepage from the seam 101 can be prevented.

[0084] In the embodiment of the underwear 1 according to the present invention and its variations described above, the placket body 20 is composed of an upper placket 3 and a lower placket 4, and is a type of underwear having openings 25, 26 for inserting and removing the male private parts. However, in another variation, the placket body 20 may be formed from a single piece of fabric and may not have the openings 25, 26.

[0085] Various embodiments and modifications have been described above, but it goes without saying that these embodiments and modifications may be combined together.
