Summary of the Invention

[0004] Since the shorts of Patent Documents 1 and 2 absorb body fluids by an absorbent pad or a sanitary napkin, if the crotch region is not properly positioned with respect to the excretory opening, there is a risk of body fluid leakage. Therefore, it is desirable to pull up the crotch region close to the excretory opening during wearing. However, as a result of the applicant's intensive investigation of the wearing mode of the shorts, there are cases where the crotch region cannot be properly positioned with respect to the excretory opening when the shorts are pulled up.

[0005] More specifically, the narrowest part of the crotch area is, in its natural state, located in front of the front-to-back center of the shorts. Also, the narrowest part of the crotch (the narrowest part of the area held between the inner thighs) is likely to be located at the boundary between the ventral and dorsal sides of the body, i.e., the front-to-back center of the shorts.

[0006] Therefore, when you pull up shorts where the narrowest part of the crotch area is located in front of the front-to-back center, the narrowest part of the body and the narrowest part of the crotch area shift in the front-to-back direction. In order to achieve the correct positional relationship between the narrowest part of the body and the narrowest part of the crotch area, it was necessary to pull the shorts upwards and then pull them backwards to align the narrowest part of the crotch area with the narrowest part of the body.

[0007] Furthermore, when attempting to pull up shorts where the narrowest part of the crotch area is located in front of the front-to-back center, by aligning the narrowest part of the crotch area with the narrowest part of the body (while pulling the narrowest part of the crotch area backward), the front part of the shorts becomes taut and rubs against the front of the thighs, making it difficult to pull the shorts up to the proper position. Alternatively, the width of the shorts positioned at the narrowest part of the crotch area may be too wide, causing the shorts to bunch up.

[0008] This invention has been made in view of these problems, and aims to provide menstrual or light incontinence shorts that can be easily pulled up to the appropriate position for the wearer. [Means for solving the problem]

[0009] One embodiment of the shorts is for menstruation or light incontinence. The shorts have a front-to-back direction extending to the wearer's abdominal and dorsal sides, a width direction perpendicular to the front-to-back direction, a front area positioned on the wearer's abdominal side, a rear area positioned on the wearer's dorsal side, and a crotch area positioned between the front and rear areas and between the wearer's legs. A rear stretchable member that stretches in the front-to-back direction is provided at the center of the width direction of the rear area. The front edge of the rear stretchable member is positioned behind the front-to-back center, which is the center of the front-to-back direction in the natural state of the shorts. In the natural state, the narrowest part of the crotch area, which has the shortest length in the width direction, is positioned at the front-to-back center. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0011] (1) Outline of the Embodiment The following matters become clear from this specification and the accompanying drawings: The invention according to Embodiment 1 is a pair of shorts for menstruation or light incontinence. The shorts have a front-to-back direction extending to the wearer's abdominal and dorsal sides, a width direction perpendicular to the front-to-back direction, a front area positioned on the wearer's abdominal side, a rear area positioned on the wearer's dorsal side, and a crotch area positioned between the front and rear areas and between the wearer's legs. A rear-stretchable member that stretches in the front-to-back direction is positioned at the center of the width direction of the rear area. The front edge of the rear-stretchable member is positioned behind the front-to-back center, which is the center of the front-to-back direction in the natural state of the shorts. In the natural state, the narrowest part of the crotch area, which has the shortest length in the width direction, is positioned at the front-to-back center. In the natural state (when the rear-stretchable member is contracted), the narrowest part of the crotch area is positioned at the front-to-back center of the shorts, and the front-to-back position of the narrowest part of the crotch area and the narrowest part of the body align, so the narrowest part of the crotch area can be aligned with the narrowest part of the body simply by pulling up the shorts. Therefore, it suppresses snagging when pulling up the shorts and makes it easier to pull up the crotch area to the appropriate position. In addition, the rear elastic member allows the shorts to be pulled up while being pulled towards the rear, so the crotch area can be pulled towards the rear and the leg opening can be widened while being pulled up. As a result, it suppresses the shorts from touching the area extending from the inner end of the thigh towards the front and the crotch area can be positioned appropriately. Furthermore, once the shorts have been pulled up, the rear elastic member located in the center of the width direction of the rear area can fit the rear area into the gap between the left and right curves of the buttocks, suppressing shifting during wear.

[0012] In a preferred embodiment, the invention according to Embodiment 2 may have the following features in the invention according to Embodiment 1. When the shorts are stretched, the narrowest part of the crotch area is located at the front-to-back center. When a wearer pulls up the shorts, they generally grasp the left and right ends of the waist opening of the shorts with their left and right hands, respectively, and pull them up while stretching them in the width direction. As a result, the shorts gradually stretch from their natural state. When the shorts are stretched, the narrowest part of the crotch area is located at the front-to-back center of the shorts, so even when the shorts are stretched when pulled up, the front-to-back position of the narrowest part of the crotch area and the narrowest part of the body align, suppressing snagging when the shorts are pulled up and making it easier to pull the crotch area up to the appropriate position.

[0013] In a preferred embodiment, the invention according to Embodiment 3 may have the following features in the invention according to Embodiment 2. The narrowest part is continuous between the front-to-back center in the natural state and the front-to-back center in the stretched state. According to this embodiment, since the narrowest part is continuous between the front-to-back center in the natural state and the front-to-back center in the stretched state, the narrowest part of the crotch area is more likely to remain in contact with the narrowest part of the crotch from the natural state when pulling up begins to the stretched state when pulling up is completed. Therefore, snagging when pulling up the shorts is suppressed, and the crotch area is more likely to be pulled up to the appropriate position. In addition, since the narrowest part of the crotch area has a certain length in the front-to-back direction, even if the shorts shift in the front-to-back direction due to changes in posture, etc., when worn, it is easier to keep the front-to-back position of the narrowest part of the crotch area and the narrowest part of the body aligned. Therefore, the rear stretchable member makes it easier to keep the rear area fitted into the gap between the left and right buttocks, and the shifting of the entire shorts can be suppressed.

[0014] According to a preferred embodiment, the invention according to Embodiment 4 may have the following features in the invention according to any one of Embodiments 1 to 3. The narrowest part of the crotch region is continuous in the front-back direction and is arranged across the front-back center in the natural state. According to this embodiment, since the narrowest part of the crotch region has a certain length in the front-back direction, even when the shorts are displaced in the front-back direction due to a change in posture or the like during wearing, it is easy to continuously align the positions in the front-back direction of the narrowest part of the crotch region and the narrowest part of the body. Therefore, it is easy to continuously fit the rear side region into the gap between the bulges of the left and right buttocks by the rear elastic member, and the displacement of the entire shorts can be suppressed.

[0015] According to a preferred embodiment, the invention according to Embodiment 5 may have the following features in the invention according to any one of Embodiments 1 to 4. In the natural state, the length in the front-back direction of the narrowest part of the crotch region located on the front side of the front-back center may be longer than the length in the front-back direction of the narrowest part of the crotch region located on the rear side of the front-back center. Generally, the movable range of the leg during walking is wider in the region on the front side of the front-back center than in the region on the rear side. By having a longer length in the front-back direction of the narrowest part located on the front side of the front-back center, it becomes easier to move the leg. Also, when the leg is moved, it is possible to suppress the shorts from being pulled back and forth, suppress the displacement of the shorts, and it is easy to continuously apply the crotch region to the body.

[0016] According to a preferred embodiment, the invention according to aspect 6 may have the following features in the invention according to any one of aspects 1 to 5. The crotch region has a surface layer that abuts against the wearer's skin and a back layer disposed on the non-skin side of the surface layer. The elongation of the back layer is higher than that of the surface layer. At the narrowest part of the crotch region, the surface layer and the back layer are separated. According to this embodiment, even at the narrowest part where the surface layer has a low elongation and a narrow width, the width of the surface layer can be ensured, and it is easy to continuously apply the surface layer to the excretion opening. In addition, since the elongation of the back layer is high, the back layer can press the surface layer against the body side, improving the fit to the body. Further, since the surface layer and the back layer are separated at the narrowest part of the crotch region, it is possible to suppress the surface layer from widening due to the expansion and contraction of the back layer, ensure the width of the surface layer, and make it easy to continuously apply the surface layer to the excretion opening.

[0017] According to a preferred embodiment, the invention according to aspect 7 may have the following features in the invention according to any one of aspects 1 to 6. The crotch region is provided with a surface layer that abuts against the wearer's skin and a back layer disposed on the non-skin side of the surface layer. In a state where the shorts in the natural state are viewed from the front side, the surface layer located on the rear side of the center in the front-rear direction is visible from the front side. When wearing the shorts, the wearer can view the skin-side surface of the front region and the skin-side surface of the crotch region, and can grasp the positions of the surface layers in the front region and the crotch region. Further, according to this embodiment, the wearer can view the surface layer of the rear region before wearing. Since the positions of the surface layers can be grasped in any of the front region, the rear region, and the crotch region, it is easy to arrange the surface layer at an appropriate position. In addition, in a form in which the surface layer has a function as an absorption layer that absorbs body fluids, it is easy to recognize that the surface layer that absorbs body fluids is arranged in a wide range, and it is easy to obtain a sense of security regarding the absorption performance.

[0018] In a preferred embodiment, the invention according to Embodiment 8 may have the following features in the invention according to any of Embodiments 1 to 7. The crotch area is provided with a surface layer that comes into contact with the wearer's skin and a back layer that is positioned on the non-skin side of the surface layer. In the crotch area, the surface layer is positioned to be separable from the back layer and has an extended portion that extends outward in the width direction from the back layer. The extended portion is provided at the narrowest part. According to this embodiment, because an extended portion is provided, the user can easily understand that two layers, a surface layer and a back layer, are arranged and that an absorbent pad can be placed between them. Therefore, the operation of attaching the absorbent pad can be performed smoothly.

[0019] In a preferred embodiment, the invention according to Embodiment 9 may have the following features in any of Embodiments 1 to 8. The shorts are provided with a pair of leg elastic members that extend from the outer part in the width direction of the leg opening to the inner part in the width direction and are arranged along the leg opening. The inner edge in the width direction of each leg elastic member overlaps with the surface side areas located on both sides of the region obtained by dividing the surface layer into three equal parts in the width direction. According to this embodiment, the surface layer can be stretched in the width direction by the leg elastic members, and wrinkles and creases in the surface layer can also be suppressed. The surface layer is the layer that comes into direct contact with the skin, and discomfort to the skin can be suppressed by suppressing wrinkles and creases. In addition, by stretching the surface layer in the width direction in the area corresponding to the groin, the width of the surface layer 10 can be suppressed, thereby suppressing leakage.

[0020] In a preferred embodiment, the invention according to Embodiment 10 may have the following features in the invention according to any of Embodiments 1 to 9: The shorts have a waist elastic member positioned along the waist opening and stretching in the width direction. The surface layer overlaps the waist elastic member. According to this embodiment, the waist elastic member can make the back layer fit around the waist and suppress the front-to-back displacement of the surface layer. The surface layer fits around the waist around the waist opening and is pulled outward in the width direction around the leg opening, making it easy to maintain a fit to the body while suppressing wrinkles and folds.

[0021] (2) Shorts according to the embodiment (2-1) Overall composition of the shorts The shorts 1 according to this embodiment will be described below with reference to the drawings. In the following drawings, identical or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratios of the dimensions, etc., may differ from those of reality. Therefore, specific dimensions, etc., should be determined by referring to the following explanation. In addition, there may be parts where the relationships and ratios of dimensions differ between drawings.

[0022] Shorts 1 are shorts for menstruation or light incontinence. Shorts for menstruation or light incontinence may be shorts that can accommodate absorbent pads such as sanitary napkins, and may be women's shorts. Shorts 1 may be worn with the absorbent pad 100 attached, or without the absorbent pad 100. The way the absorbent pad 100 is attached may be as shown in Figure 8, where the absorbent pad 100 is placed on the inner surface of Shorts 1 and the wings of the absorbent pad are attached to the inside of the shorts, or as shown in Figure 9, where the entire absorbent pad is housed inside Shorts 1. Furthermore, Shorts 1 may be configured to absorb bodily fluids excreted from the wearer, and may be absorbent shorts equipped with an absorbent layer that absorbs bodily fluids such as menstrual blood. Examples of bodily fluids to be absorbed include menstrual blood, urine, and vaginal discharge. Shorts 1 do not have to have pulp and SAP like disposable absorbent articles. Shorts 1 may be reusable shorts, not disposable shorts.

[0023] The absorbent pad 100 comprises an absorbent layer that absorbs bodily fluids. The absorbent pad 100 may be disposable or reusable. The absorbent layer may have an absorbent material such as pulp or superabsorbent polymer (SAP). Alternatively, the absorbent layer may have fibers and be configured to temporarily absorb bodily fluids by holding them in the gaps between the fibers. The absorbent pad 100 may be configured so that washing removes the bodily fluids between the fibers, and drying the absorbent pad 100 allows the moisture between the fibers to evaporate, returning it to its state before bodily fluid absorption. As shown in Figure 8, the absorbent pad 100 attached to the skin-side T1 of the shorts may have a top sheet 101 that comes into contact with the wearer's skin, a back sheet 102 positioned on the non-skin side of the absorbent layer and in contact with the skin-side surface of the shorts 1, and wings 105 that are folded back along the outer edge of the crotch area S3 of the shorts 1 when worn. A wing fastening portion 107 may be provided on the non-skin side T2 of the wing 105 for fastening the wing 105 to the shorts 1. In addition, a main body fastening portion 106 may be provided in the area of ​​the back sheet 102 that is in the width direction W of the wing 105 for fastening the area in the width direction W of the back sheet 102 to the shorts 1. The wing fastening portion 107 and the main body fastening portion 106 may be areas to which adhesive has been applied. Furthermore, as shown in Figure 9, the absorbent pad 100 placed inside the shorts 1 may have an absorbent layer that holds bodily fluids and a waterproof layer placed on the non-skin side of the absorbent layer. The waterproof layer may be a liquid-impermeable sheet and may be mainly composed of non-absorbent fibers, and specifically may be composed of a polyester sheet and a polyurethane sheet laminated on the polyester sheet.

[0024] Figures 1 to 4 are plan views of the shorts 1 with the non-skin side T2 facing outwards. Figures 1 and 2 show the shorts in their natural state, while Figures 3 and 4 show the shorts in their stretched state. Figures 1 and 3 are front views seen from the front, and Figures 2 and 4 are rear views seen from the back. The state with the non-skin side T2 facing outwards is the state in which the shorts 1 are normally worn. Figures 5 and 6 are plan views of the stretched shorts 1 with the skin side T1 facing outwards; Figure 5 is a front view seen from the front, and Figure 6 is a rear view seen from the back. Figure 7(A) is a partial cross-sectional view of the front area S1 along line AA shown in Figure 1, (B) is a partial cross-sectional view of the rear area S2 along line BB shown in Figure 2, (C) is a partial cross-sectional view of the front area S1 along line CC shown in Figure 5, and (D) is a partial cross-sectional view of the crotch area S3 along line DD shown in Figure 5. For the sake of clarity in the drawings, the areas where each component is in contact also include portions where the components are shown separated from each other.

[0025] In this invention, unless otherwise specified, the range of position, length, and area refers to the range of position, length, and area in the natural state. The "natural state" refers to the state when the shorts 1 are left for a predetermined period of time. For example, the shorts are stretched by pulling them outwards in the left-right direction, and this stretched state is maintained for 15 seconds. Then, the tension on the shorts 1 is released and they are placed on a flat surface such as a desk. The state after 12 hours in this flat position is considered the natural state. The "stretched state" refers to the state in which the shorts are stretched in the width direction and front-back direction so that wrinkles caused by elastic members such as the back-stretchable member are eliminated as much as possible.

[0026] In this invention, the outer part refers to a portion occupying a certain range in the width direction W, including the outer edge in the width direction W, and the outer edge refers to the outer edge in the width direction W. The outer edge of a component that occupies a certain range in the front-rear direction is the edge that connects points located on the outside in the width direction of the component over the entire component. In this invention, the inner part refers to a portion occupying a certain range in the width direction W, including the inner edge in the width direction W, and the inner edge refers to the inner edge in the width direction W. The inner edge of a component that occupies a certain range in the front-rear direction is the edge that connects points located on the inside in the width direction of the component over the entire component. Furthermore, in this invention, the front end and rear end refer to a portion occupying a certain range in the front-rear direction L, including the edge in the front-rear direction L, and the front end edge and rear end edge refer to the edge in the front-rear direction L. The outer end includes the front end and rear end, and the outer end edge includes the front end edge and rear end edge. The outer edge is a concept that includes the outer end edge and the outer edge, and the outer edge portion is a concept that includes the outer end and the outer portion. Furthermore, the inner edge is an edge that includes the inner edge and extends along the front-to-back direction L. The outer edge is an edge that includes the outer edge and extends along the front-to-back direction L. In this specification, the term "along the front-to-back direction L" means a direction with an angle of less than 45° with respect to the front-to-back direction L, and the term "along the width direction W" means a direction with an angle of less than 45° with respect to the width direction W.

[0027] The shorts 1 may have a front-to-back direction L extending to the wearer's ventral and dorsal sides, a width direction W perpendicular to the front-to-back direction L, and a thickness direction T. The thickness direction T is the direction extending towards the wearer's skin side (inside) T1 and the opposite side of the wearer's skin side (outside) T2. The planar direction of the shorts 1 is the direction extending in the front-to-back direction L and the width direction W.

[0028] The shorts 1 are pant-type and have a pair of leg openings 52 and a waist opening 51. The shorts 1 have a front area S1 positioned on the wearer's abdominal side, a rear area S2 positioned on the wearer's back side, and a crotch area S3 positioned between the front area S1 and the rear area S2. The crotch area S3 is positioned between the wearer's legs and is sandwiched between the pair of leg openings 52. The waist opening 51 is defined by the front edge of the front area S1 and the rear edge of the rear area S2. The crotch area S3 is the area sandwiched in the width direction W by the pair of leg openings 52. The front edge of the crotch area S3 coincides with the front edge of the leg opening 52, and the rear edge of the crotch area S3 coincides with the rear edge of the leg opening 52.

[0029] The front area S1 and the rear area S2 are connected at the sides of the waist. The material constituting the front area S1 may be continuous with the material constituting the rear area S2, or it may be a different material. The outer layer 30, described later in this embodiment, is continuous in the front-rear direction L and extends from the crotch area S3 to the rear area S2 and the front area S1, respectively. The outer part of the outer layer 30 in the width direction W that extends to the rear area S2 extends to the front area S1, and in the front area S1, it is joined to the outer layer 30 that extends from the crotch area S3 to the front area S1. Figure 1 shows the joint 25 between these outer layers 30. The joint 25 may be located in the front area S1 as in this embodiment, or in the rear area S2, or at the boundary between the front area S1 and the rear area S2.

[0030] The length L in the front-to-back direction of the front area S1 is the length L in the front-to-back direction from the front edge of the leg opening 52 to the front edge of the front area S1. The length L in the front-to-back direction of the rear area S2 is the length L in the front-to-back direction from the rear edge of the leg opening 52 to the rear edge of the rear area S2. The length L in the front-to-back direction of the crotch area S3 is the length L in the front-to-back direction from the front edge of the leg opening 52 to the rear edge of the leg opening 52. The length L in the front-to-back direction of the crotch area S3 may be longer than the length L in the front-to-back direction of the front area S1 and may be longer than the length L in the front-to-back direction of the rear area S2. Also, in the pant-type state shown in Figure 1, the length L in the front-to-back direction of the leg opening 52 (for example, the length from the outer edge of the leg opening 52 in the front-to-back direction to the front-to-back center 1CL, which is the center L in the front-to-back direction of the shorts 1) may be longer than the length in the front-to-back direction of the area outside the leg opening 52 in the front-to-back direction L (the length in the front-to-back direction of the area surrounding the waist). The shorts 1 in this embodiment are not boxer shorts, but rather shorts in which the length L in the front-to-back direction of the leg opening 52 accounts for 50% or more of the total length of the shorts in the front-to-back direction.

[0031] The shorts 1 have a main body side area RS located on the side in the width direction W of the region obtained by dividing the shorts 1 into three equal parts in the width direction, and a main body central area RC located in the center of the region obtained by dividing the shorts 1 into three equal parts. In the case where the length of the shorts 1 in the width direction W changes, the region obtained by dividing the shorts 1 into three equal parts is defined based on the longest position. The crotch area S3 has a crotch central area S33 located in the center of the region obtained by dividing the crotch area S3 into three equal parts in the front-to-back direction L, a crotch front area S31 located in front of the crotch central area S33 of the region obtained by dividing the region by three equal parts, and a crotch rear area S32 located behind the crotch central area S33 of the region obtained by dividing the region by three equal parts. In the case where the length of the crotch area S3 in the front-to-back direction L changes, the region obtained by dividing the shorts 1 into three equal parts is defined based on the longest position.

[0032] The shorts 1 may have a surface layer 10 and a back layer 20. The surface layer 10 is in contact with the wearer's skin. The back layer 20 is positioned on the non-skin side T2 of the surface layer 10. The back layer 20 only needs to be positioned on the non-skin side T2 of the surface layer 10, and may be in contact with the non-skin side T2 surface of the surface layer 10, or other layers may be sandwiched between the surface layer 10 and the back layer 20. In addition, the back layer 20 may constitute the non-skin side T2 surface of the shorts 1, or the non-skin side T2 surface may be covered by other layers.

[0033] The surface layer 10 and the back layer 20 may be positioned in at least the crotch area S3. In this embodiment, the surface layer 10 and the back layer 20 are positioned across the crotch area S3, the front area S1, and the rear area S2. The surface layer 10 and the back layer 20 are not integrated and may be composed of separate components. The materials constituting the surface layer 10 and the materials constituting the back layer 20 may be of the same type or different types. The surface layer 10 may be made of, for example, fabric, but its material is not particularly limited, and examples include fabrics containing at least one of nylon, polyurethane, polyester, and cotton. The back layer 20 may be a layer with lower liquid permeability to the non-skin side T2 than the surface layer 10, and may be a water-repellent layer or a liquid-impermeable layer (waterproof layer). The back layer 20 may be made of, for example, fabric, but its material is not particularly limited, and may be made of, for example, a polyester sheet or a polyurethane sheet. The inner layer 20 may have an outer layer 30 that covers the non-skin side. The outer layer 30 may constitute the non-skin side of the entire shorts 1. The outer layer 30 may be made of, for example, fabric, but its material is not particularly limited, and examples include fabrics containing at least one of nylon, polyurethane, polyester, and cotton.

[0034] The back layer 20 may be a layer in which the rate of transfer of bodily fluids from the skin side T1 to the non-skin side T2 is lower than that of the surface layer 10. The surface layer 10 and the back layer 20 are cut from the product into 5cm x 5cm pieces and placed on a flat surface, and one drop of simulated bodily fluid is dropped onto the skin side T1 of each material. The time that the simulated bodily fluid remains on the material in a bead is used for comparison. Materials in which the simulated bodily fluid is absorbed for a short time are judged to have high liquid permeability, while materials in which the simulated bodily fluid is absorbed for a long time or in which the simulated bodily fluid is not absorbed are judged to have low liquid permeability.

[0035] As shown in Figure 7(C), the front area S1 may have a surface layer 10, a back layer 20, and an outer layer 30 laminated in order from the skin side T1 to the non-skin side T2. The surface layer 10 and the back layer 20 are arranged in the entire width direction of the central area RC of the main body and in a part of the side area RS of the main body. The outer layer 30 is arranged in the entire area of ​​the shorts 1 and may constitute the non-skin side surface of the entire shorts 1.

[0036] The surface layer 10 has a surface side region R12 located on the side in the width direction W of a region obtained by dividing the surface layer 10 into three equal parts in the width direction, and a surface central region R11 located in the center of the divided region. The back layer 20 has a back side region R22 located on the side in the width direction W of a region obtained by dividing the back layer 20 into three equal parts in the width direction, and a back central region R21 located in the center of the divided region. In the case where the length of the surface layer 10 in the width direction and the length of the back layer 20 in the width direction W change, the region is defined as being divided into three equal parts based on the longest position.

[0037] (2-2) Containment space between the surface layer and the back layer In at least the crotch area S3, the surface layer 10 and the back layer 20 may be arranged to be separable. Because the surface layer 10 and the back layer 20 are configured to be separable, the wings of the absorbent pad can be inserted into the separated gap (see Figure 8), or the entire absorbent pad can be housed in the gap (see Figure 9). The area where the surface layer 10 and the back layer 20 are separated only needs to be a certain range extending inward in the width direction W from the outer edge of the crotch central area S33, and may be the entire crotch central area S33, or a part of the crotch central area S33 including the outer part. For example, the surface layer 10 and the back layer 20 may be joined at the center of the width direction W of the crotch central area S33. The length of the area where the surface layer 10 and the back layer 20 are separated in the width direction W may be greater than or equal to the length of the wing in the width direction W, and may be, for example, a range of 30 mm or more from each of the outer edges of the crotch central area S33. Preferably, the region where the surface layer 10 and the back layer 20 are separated may be provided over the entire width W of the central area S33 of the crotch.

[0038] The state in which the surface layer 10 and the back layer 20 can be separated refers to the state in which they can be separated under normal wear conditions and when the wearer pulls the two layers apart by hand. A state in which the surface layer 10 and the back layer 20 cannot be separated under normal wear conditions due to adhesive, seams, welding, etc. For example, a state in which the surface layer 10 and the back layer 20 are not joined by seams, etc., but are temporarily joined by entanglement due to fuzziness of the fibers, or by static electricity, can be separated by hand and are therefore included in the state in which they can be separated.

[0039] The crotch area S3 may be provided with a storage space S capable of accommodating an absorbent pad between the surface layer 10 and the back layer 20, and a storage edge 60 that surrounds the storage space, formed by the joining of the surface layer 10 and the back layer 20. The storage space S is a region formed between the surface layer 10 and the back layer 20 when they are separated. That is, the surface layer 10 and the back layer 20 in contact with the storage space S are configured to be separable. The storage edge 60 is formed by the portion where the surface layer 10 and the back layer 20 are joined, and is provided adjacent to the storage space S. The storage space S only needs to be provided in the crotch area S3. The storage space S may extend from the crotch area S3 to the front area S1, or from the crotch area S3 to the rear area S2. In this embodiment, the storage space S is provided continuously across the crotch area S3, the front area S1, and the rear area S2.

[0040] (2-3) Extended portion of the surface layer In the crotch area S3, the surface layer 10 may have an extended portion 15 that extends outward in the width direction W from the back layer 20. The extended portion 15 is a region of the surface layer 10 that extends outward in the width direction W from the back layer 20. The extended portion 15 may be arranged to straddle the front-to-back center 1CL, and the length in the front-to-back direction L of the extended portion 15 in front of the front-to-back center 1CL may be longer than the length in the front-to-back direction L of the extended portion 15 behind the front-to-back center 1CL. The extended portion 15 may be provided in a part of the front-to-back direction L of the crotch central area S33. In this embodiment, it is provided over the entire front-to-back direction L of the crotch central area S33. The length in the width direction W of the extended portion 15 is not limited, but may be 2 mm or more and 5 mm or less. The provision of the extended portion makes it easier to separate the surface layer 10 and the back layer 20 when inserting the absorbent pad through the insertion opening 68, and makes it easier to open the insertion opening 68. The length L in the front-to-back direction of the extension may be 10 mm or more.

[0041] Figure 8 is a diagram illustrating how the absorbent pad 100 is attached to the skin-facing side of the shorts 1. Figures 8(A), (C), and (E) show the attachment of the absorbent pad 100 as viewed from the skin side of the crotch area S3 of the shorts, while Figures 8(B), (D), and (F) show the attachment of the absorbent pad 100 in a cross-section based on a cross-section passing through the center in the front-to-back direction L of the central crotch area S33 and along the width direction W.

[0042] As shown in Figures 8(A) and (B), the extended portion 15 of the surface layer 10 extends outward in the width direction W than the back layer 20. As shown in Figures 8(C) and (D), when the wearer attaches the absorbent pad 100, they place the absorbent pad 100 against the crotch area S3 of the shorts and fold back the wings 105 of the absorbent pad 100 along the outer edge of the central crotch area S33. At this time, in the central crotch area S33, the surface layer 10 that the absorbent pad 100 contacts extends outward in the width direction W, so the wings 105 can be folded against only the surface layer 10. Therefore, when folding back the wings 105 of the absorbent pad 100, it is suppressed that both the surface layer 10 and the back layer 20 are sandwiched together, and it is easy to insert the wings 105 between the surface layer 10 and the back layer 20. Furthermore, as shown in Figures 8(E) and (F), by folding back the wing 105 at the extended portion 15 of the surface layer 10, it becomes easier to raise only the surface layer 10, creating a gap between the surface layer 10 and the back layer 20, and making it easier to insert the wing 105 between the surface layer 10 and the back layer 20. Therefore, the wing 105 of the absorbent pad 100 can be easily and appropriately attached to the crotch area S3.

[0043] The extension portion 15 may be provided on both outer sides in the width direction W of the surface layer 10. The wings 105 can be easily and appropriately folded back at either the left or right outer edge of the crotch central area S33 and positioned between the surface layer 10 and the back layer 20. Furthermore, when viewing the crotch central area S33 from the skin side, the back layer 20, which is located on the non-skin side, is not visible at either the left or right outer edge of the crotch central area S33. Therefore, it is easy to align the position of the absorbent pad with the center of the crotch central area S33 in the width direction W using the outer edges of the crotch central area S33 as a guide.

[0044] The region where the surface layer 10 and the back layer 20 are spaced apart, and the extension portion 15, may be positioned across the crotch front area S31 and the crotch central area S33. Since the excretory openings (urinary opening and vaginal opening) are located towards the front, the center of the front-to-back L of the wing 105 of the absorbent pad 100 can be positioned towards the front.

[0045] In this embodiment, the extension 15 spans the front crotch area S31, the central crotch area S33, and the rear crotch area S32. The length of the extension 15 in the width direction W may vary or remain constant. In the case where the length of the extension 15 in the width direction W varies, the position where the length of the extension 15 in the width direction W is longest may be located in the central crotch area S33. The center of the extension 15 in the front-to-back direction L may be located in front of the center of the crotch area S3 in the front-to-back direction L.

[0046] In this embodiment, the region in which the surface layer 10 and the back layer 20 are spaced apart spans the crotch area S3, the front area S1, and the back area S2. Between the surface layer 10 and the back layer 20, either the wings 105 of the absorbent pad 100 or the absorbent pad body that absorbs bodily fluids may be inserted. The shorts 1 of this embodiment are configured to be used in either a configuration in which the absorbent pad 100 is placed on the skin side T1 of the crotch area S3 and the wings 105 of the absorbent pad 100 are placed between the surface layer 10 and the back layer 20, or a configuration in which the absorbent pad body is placed between the surface layer 10 and the back layer 20 and bodily fluids are guided to the absorbent pad 100 via the surface layer 10.

[0047] The outer edge of the extension portion 15 in the width direction W may have a straight section that extends linearly along the front-to-back direction L. According to this embodiment, the wing 105 is easier to fold along the straight section and is easier to fold without twisting. The straight section may be positioned across the front-to-back center 1CL of the shorts, and the length of the straight section in the front-to-back direction L in front of the front-to-back center 1CL may be longer than the length of the straight section in the front-to-back direction L in rear of the front-to-back center 1CL. The length of the straight section in the front-to-back direction L may be 20 mm or more, preferably 30 mm or more. The range of the straight section in the front-to-back direction may be the same as the range of the narrowest part in the front-to-back direction, as described later.

[0048] The length L in the front-rear direction of the extension portion 15 may be longer than the length L in the front-rear direction of the wing 105 at the position of the inner edge in the width direction W of the wing fastening portion 107 attached to the non-skin side T2 surface of the wing 105. According to this embodiment, when the wing 105 is folded back using the inner edge of the wing fastening portion 107 as a starting point, the length L in the front-rear direction of the extension portion 15 is longer than the length L in the front-rear direction of the folded portion of the wing 105, allowing the wing 105 to be folded back along the extension portion 15. The length L in the front-rear direction of a typical wing fastening portion 107 is 10 mm or more. Therefore, the length L in the front-rear direction of the extension portion 15 may be 10 mm or more.

[0049] The length L in the front-rear direction of the extension portion 15 may be longer than the length L in the front-rear direction of the base of the wing 105. According to this embodiment, when the wing 105 is folded back using the base of the wing 105 as the pivot point, the length L in the front-rear direction of the extension portion 15 is longer than the length L in the front-rear direction of the folded portion of the wing 105, allowing the wing 105 to be folded back along the extension portion 15. The length L in the front-rear direction of the base of the wing 105 is the length of a virtual line connecting the inner edge of the front side of the wing 105 and the inner edge of the rear side of the wing 105. The length L in the front-rear direction of the base of a typical wing 105 is 20 mm or more. Therefore, the length L in the front-rear direction of the extension portion 15 may be 20 mm or more.

[0050] The length in the width direction W of the extension portion 15 may be shorter than the length in the width direction W of the wing 105. According to this embodiment, since the length in the width direction W of the wing 105 folded back with the extension portion 15 as the base point exceeds the length in the width direction W of the extension portion 15, the folded wing 105 can be inserted between the surface layer 10 and the back layer 20. In addition, the length in the width direction W of the area in the crotch central region S33 where the surface layer 10 and the back layer 20 are spaced apart may be twice or more the length in the width direction W of the wing 105. According to this embodiment, interference between wings 105 inserted from both sides can be suppressed. The length in the width direction W of the wing 105 is the distance in the width direction W between the above-mentioned imaginary line and the outer edge of the wing 105. The length in the width direction W of a typical wing 105 is 30 mm or more. Therefore, the length in the width direction W of the wing 105 may be 30 mm or more.

[0051] The length of the extension portion 15 in the width direction W may be longer than the distance in the width direction W between the inner edge of the wing fastening portion 107 attached to the non-skin side T2 surface of the wing 105 and the base of the wing 105. According to this embodiment, when the wing 105 is folded back from the base, the wing fastening portion 107 can be fastened to the non-skin side surface of the surface layer 10. The distance in the width direction W between the inner edge of the wing fastening portion 107 and the base of the wing 105 is generally 10 mm or more. Therefore, the length of the extension portion 15 in the width direction W may be 10 mm or more.

[0052] (2-4) Bending stiffness The bending rigidity of the surface side region R12 may be higher than that of the surface center region R11. When folding back the wing 105, the wing 105 is folded back using the outer part of the surface side region R12 as the pivot point. When folding back the folded wing 105 to the non-skin side T2, a force toward the skin side T1 is applied to the surface side region R12 by the force of inserting the folded wing 105 or pressing it against the non-skin side surface of the surface layer 10, creating a gap between the surface layer 10 and the back layer 20. At this time, because the bending rigidity of the surface side region R12 is high, it is easy to deform toward the skin side relative to the surface center region R11, and it is easy to form a wide gap between the surface layer 10 and the back layer 20. In addition, because the bending rigidity of the surface side region R12 is high, it is suppressed from folding together with the wing 105 when folding back the wing 105, maintaining the position of the surface layer 10 and allowing only the wing 105 to be folded back.

[0053] Here, the bending stiffness can be measured by the KES method. Specifically, this can be done using the KES-FB2-AUTO-A bending test machine manufactured by Kato Tech Co., Ltd., and a sample of a measurable size is prepared. Next, each sample is fixed between the chucks of the test machine so that the bending stiffness in the width direction W can be measured for each sample. The sample is bent to the front side to the maximum curvature of +2.5 cm⁻¹, then bent to the back side to the maximum curvature of -2.5 cm⁻¹, and then returned to its original position. The bending stiffness value is calculated from the average value of the slope of the bending moment with respect to curvature when bending to the front side begins and the slope of the bending moment with respect to curvature becomes almost constant, and when bending to the back side begins and the slope of the bending moment with respect to curvature becomes almost constant. This is repeated 5 times for each sample, and the average value is taken as the bending stiffness.

[0054] The bending rigidity of the extension portion 15 may be higher than that of the bending rigidity of the central surface region R11. According to this embodiment, because the bending rigidity of the extension portion 15 is high, the extension portion 15 deforms more easily toward the skin side relative to the central surface region R11, making it easier to form a wider gap between the surface layer 10 and the back layer 20. In addition, because the bending rigidity of the extension portion 15 is high, it is suppressed from folding together with the wing 105 when the wing 105 is folded back, maintaining the position of the surface layer 10 and allowing only the wing 105 to be folded back.

[0055] The bending rigidity of the back layer 20 may be higher than that of the front layer 10. According to this embodiment, when the wing 105 is bent and attached to the front layer 10, the front layer 10 deforms, while the back layer 20 maintains its shape without excessive deformation, making it easier to form a gap between the front layer 10 and the back layer 20.

[0056] (2-5) First joint and second joint A first joint may be provided in front of the central crotch area S33, where the surface layer 10 and the back layer 20 are joined. A second joint may be provided behind the central crotch area S33, where the surface layer 10 and the back layer 20 are joined. In this embodiment, the first joint is composed of a first crotch edge portion 611, which will be described later, and the second joint is composed of a second crotch edge portion 612, which will be described later. The first joint portion 611 and the second joint portion 612 are portions where the surface layer 10 and the back layer 20 are joined by seams, adhesive, welding, etc. In this embodiment, the first joint portion and the second joint portion are composed of seams. The extension portion 15 may be provided continuously in the region sandwiched between the first joint portion and the second joint portion in the front-rear direction L. According to this embodiment, since the extension portion 15 is provided between the first joint portion and the second joint portion, it is easier to deform the surface layer 10 so that it lifts towards the skin side with the first joint portion and the second joint portion as reference points, and it becomes easier to form a gap between the back layers 20. Furthermore, the region in which the surface layer 10 and the back layer 20 are arranged to be separated from each other may be provided continuously in the region sandwiched between the first joint portion and the second joint portion in the front-rear direction L.

[0057] The first joint may extend inward in the width direction W from both outer edges of the crotch area S3 in the width direction W. The second joint may extend inward in the width direction W from both outer edges of the crotch area S3 in the width direction W. In this embodiment, since the first and second joints extend along the width direction W, the space between the surface layer 10 and the back layer 20 extends in the width direction W from the outer edge of the crotch area S3, making it easier to insert the wing 105 inward in the width direction W along the joint. In this embodiment, the first and second joints extend linearly along the width direction W from the outer edge of the crotch area S3.

[0058] The first joint on one side in the width direction W and the first joint on the other side in the width direction W may be spaced apart in the width direction W. According to this embodiment, a region is formed between the first joints in which the surface layer 10 and the back layer 20 are not joined, and a region is formed between the second joints in which the surface layer 10 and the back layer 20 are not joined. Therefore, when folding the wing 105 back using the outer edge of the crotch area S3 in the width direction W as a starting point, the unjointed region is easily deformed, making it easier to fold the wing 105 back using the outer edge of the crotch area S3 as a starting point. In addition, in a usage configuration in which an absorbent pad 100 is inserted into the space between the surface layer 10 and the back layer 20, a region for inserting the absorbent pad 100 can be secured in the region between the left and right first joints and the region between the left and right second joints. The distance between the first joints and the distance between the second joints may be 30 mm or more.

[0059] (2-6) Insertion opening and housing edge An insertion opening 68 for the absorbent pad may be provided on the outer side of the crotch area S3 in the width direction W, communicating with the storage space S. The insertion opening 68 is positioned so as to be separable from the surface layer 10 and the back layer 20. Because the insertion opening 68 is provided on the outer side of the crotch area S3, the absorbent pad 100 can be inserted and removed from the outer side of the crotch area S3. The position of the absorbent pad in the crotch area S3 can be adjusted, and because the distance from the crotch area S3 to either the front area S1 or the rear area S2 is short, it is easy to adjust the position of the absorbent pad 100 regardless of whether the absorbent pad is placed in the front area S1 or the rear area S2. The insertion opening 68 only needs to be provided in at least a part of the range L in the front-to-back direction of the crotch area S3, and preferably it may be provided in the central crotch area S33.

[0060] The receiving edge portion 60 may have a crotch edge portion 61 extending outward in the front-rear direction from the insertion opening, and an outer edge portion 65 located further outward in the front-rear direction L than the crotch edge portion 61, and further outward in the width direction W than the crotch edge portion 61. The crotch edge portion 61 is an edge adjacent to the insertion opening 68 in the front-rear direction L, and is provided on at least one of the front and rear sides of the insertion opening 68. In this embodiment, the crotch edge portion 61 is provided on both the front and rear sides of the insertion opening 68. The outer edge portion 65 is provided on at least one of the front and rear sides of the crotch edge portion 61. In this embodiment, the outer edge portion 65 is provided on both the front and rear sides of the insertion opening 68. The outer edge portion 65 only needs to be located further outward in the width direction W than at least a part of the crotch edge portion 61, and may be located further outward in the width direction W than the outer edge of the crotch edge portion 61 in the front-rear direction L.

[0061] The storage space S is partitioned by the crotch edge 61 in the region extending in the front-rear direction L from the insertion opening 68, and partitioned by the outer edge 65 beyond the crotch edge 61 in the front-rear direction L. Since the outer edge 65 is located outside the width direction W of the crotch edge 61, the length in the width direction W of the storage space S partitioned by the outer edge 65 is longer than the length in the width direction of the storage space S partitioned by the crotch edge 61. Therefore, an absorbent pad placed outside the front-rear direction L and outside the width direction W beyond the crotch edge 61 will catch on the crotch edge 61, preventing it from shifting inward in the front-rear direction. Furthermore, compared to a configuration where the length in the width direction W of the storage space S is constant, the position where the width direction length of the storage space S changes can be used as a guide for positioning, making it easier to place the absorbent pad in the desired position.

[0062] Figure 9 is a diagram illustrating how the absorbent pad 100 is attached to the shorts 1. Figures 9(A), (C), and (E) show how the absorbent pad 100 is attached when viewed from the skin side of the crotch area S3 of the shorts, and Figures 9(B), (D), and (F) show how the absorbent pad 100 is attached in a cross section based on a cross section that passes through the center in the front-to-back direction L of the crotch area S3 and is along the width direction W. When attaching the absorbent pad 100 to the shorts 1, pull the surface layer 10 and the back layer 20 at the insertion opening in a direction that separates them to open the insertion opening 68. Then, insert the absorbent pad 100 through the insertion opening 68. In an embodiment in which the absorbent pad 100 is placed only in the crotch area S3, the inserted absorbent pad 100 is flattened in the crotch area S3. In an embodiment in which the absorbent pad is also placed in the front area S1 or the rear area S2, a hand is inserted through the opening to place the absorbent pad in the front area or the rear area and flatten the absorbent pad.

[0063] Figures 9(C) and (D) show the absorbent pads positioned in the crotch area S3 and the front area S1, while Figures 9(E) and (F) show the absorbent pads also positioned in the rear area S2. If the widthwise length of the outer end of the absorbent pad 100 in the front-to-back direction L is longer than the central part of the absorbent pad in the front-to-back direction, the wider portion of the absorbent pad is positioned outside the front-to-back direction L and outside the widthwise direction W relative to the crotch edge 61. This prevents the absorbent pad 100 from catching on the crotch edge 61 and shifting inward in the front-to-back direction.

[0064] The crotch edge portion 61 and the outer edge portion 65 may be connected. In this embodiment, since the crotch edge portion 61 and the outer edge portion 65 are connected, a continuous space enclosed by the crotch edge portion 61 and the outer edge portion 65 can be formed. Compared to a configuration in which the crotch edge portion 61 and the outer edge portion 65 are spaced apart, this suppresses snagging of the absorbent pad within the containment space S and allows the absorbent pad to be positioned smoothly. In a modified example, the crotch edge portion 61 and the outer edge portion 65 may be spaced apart.

[0065] The crotch edge portion 61 may have a first crotch edge portion 611 extending forward from the insertion opening 68, and a second crotch edge portion 612 extending backward from the insertion opening 68. That is, the crotch edge portion 61 may be provided on both sides in the front-rear direction L relative to the insertion opening 68. The outer edge portion 65 may have a first outer edge portion 651 located forward of the first crotch edge portion 611 and further out in the width direction W than the first crotch edge portion 611, and a second outer edge portion 652 located behind the second crotch edge portion 612 and further out in the width direction W than the second crotch edge portion 612. That is, the outer edge portion 65 may be provided on both sides in the front-rear direction L relative to the crotch edge portion 61.

[0066] According to this embodiment, when the absorbent pad is positioned outside the front-rear direction L and outside the width direction W of the first crotch edge portion 611, the first crotch edge portion 611 prevents the absorbent pad from shifting to the rear, and when the absorbent pad is positioned outside the front-rear direction L and outside the width direction W of the second crotch edge portion 612, the second crotch edge portion 612 prevents the absorbent pad from shifting to the front. As a result, the absorbent pad is less likely to shift to the front or rear, and the displacement of the absorbent pad in the front-rear direction L can be suppressed.

[0067] The first crotch edge portion 611 may extend inward in the width direction W from both outer edges in the width direction W of the crotch area S3. The second crotch edge portion 612 may extend inward in the width direction W from both outer edges in the width direction W of the crotch area S3. According to this embodiment, since the first crotch edge portion 611 and the second crotch edge portion 612 extend along the width direction W, the accommodation space S between the surface layer 10 and the back layer 20 extends in the width direction W from the outer edge of the crotch area S3, making it easier to insert the absorbent pad into the accommodation space S along the crotch edge portion. In this embodiment, the first crotch edge portion 611 and the second crotch edge portion 612 extend linearly along the width direction W from the outer edge of the crotch area S3. The first crotch edge on one side in the width direction W and the first crotch edge on the other side in the width direction W are spaced apart in the width direction W, and the second crotch edge on one side in the width direction W and the second crotch edge on the other side in the width direction W may also be spaced apart in the width direction W. Furthermore, the outer edge portion 65 in this embodiment is the portion located outside in the front-rear direction of the receiving edge portion that extends inward in the width direction W from both outer edges of the crotch area S3 in the width direction W, excluding the receiving front edge portion and receiving rear edge portion described later.

[0068] The insertion openings 68 may be provided on both outer sides in the width direction W of the crotch area S3. According to this embodiment, the absorbent pad can be inserted and removed from either the left or right outer edge of the crotch area S3, improving ease of attachment. Furthermore, the storage space S communicating with the left insertion opening 68 and the storage space S communicating with the left insertion opening 68 may be connected. That is, a continuous storage space S is provided from the left insertion opening 68 to the right insertion opening 68. According to this embodiment, the absorbent pad can be placed by inserting hands from both the left and right sides, making it easier to place the absorbent pad more appropriately inside the shorts 100.

[0069] The maximum length in the width direction W of the storage space S in the front area S1 and the maximum length in the width direction W of the storage space S in the rear area S2 may be longer than the maximum length of the storage space S in the crotch area S3. Absorbent pads can be placed over a wide area in the front area S1 and the rear area S2 to ensure sufficient absorption capacity. In addition, the maximum length in the width direction W of the storage space S in the front area S1 may be longer than the maximum length in the width direction W of the storage space S in the rear area S2. According to this embodiment, when the shorts 1 deform due to changes in posture, etc., the front area S1 has a wide storage space S at the front, so it can absorb the deformation and prevent wrinkles from forming, thus maintaining a good fit to the body. Since the excretory openings (urinary opening and vaginal opening) are located towards the front, improving the fit at the front can suppress leakage.

[0070] The storage edge portion 60 may have a storage front edge portion 66 provided along the front edge of the storage space S of the front area S1. The storage front edge portion 66 demarcates the front edge of the storage space S. The storage front edge portion 66 may be continuous along the width direction W. According to this embodiment, since the storage front edge portion 66 is continuous in the width direction W, problems such as the edges of materials such as the surface layer 10 curling up or wrinkles forming when the shorts 1 are pulled up can be suppressed. In addition, force is more easily transmitted to both the surface layer 10 and the back layer 20 via the storage front edge portion 66, making it easier to pull up both the surface layer 10 and the back layer 20.

[0071] The storage edge portion 60 may have a storage rear edge portion 67 provided along the rear end edge of the storage space S in the rear area S2. The storage rear edge portion 67 is continuous along the width direction W. The storage rear edge portion 67 demarcates the rear end edge of the storage space S. According to this embodiment, since the storage rear edge portion 67 is continuous in the width direction W, problems such as the edges of materials such as the surface layer 10 curling up or wrinkles forming when the shorts 1 are pulled up can be suppressed. In addition, force is more easily transmitted to both the surface layer 10 and the back layer 20 via the storage rear edge portion, making it easier to pull up both the surface layer 10 and the back layer 20.

[0072] As shown in Figure 6, the position P1 where the width W of the storage space S in the rear area S2 is maximum may be located in front of the rear center line S2CL, which is the front-to-back center 1CL of the shorts 1 and bisects the rear edge of the rear area S2 in the front-to-back direction L. If the width W of the storage space S is long, the absorbent pad 100 will move within the storage space S and be more likely to shift. However, by positioning the maximum width P1 in front of the rear center line S2CL, the longer portion of the storage space S in the width direction is located in a position where body pressure is easily applied when sitting, thereby suppressing the displacement of the absorbent pad 100. Therefore, the storage space S of the rear area S2 can be secured while suppressing the displacement of the absorbent pad 100.

[0073] In the natural state of the shorts 1, the center L in the anterior-posterior direction of the insertion opening 68 may be located in front of the anterior-posterior center 1CL of the shorts 1. Since the excretory openings (urinary opening and vaginal opening) are located towards the front, shifting the center of the insertion opening in the anterior-posterior direction towards the front makes it easier to adjust the position near the excretory openings. The center L in the anterior-posterior direction of the insertion opening 68 is the midpoint of the region between the first crotch edge 611 and the second crotch edge 612.

[0074] (2-7) Rear expandable member A rear-stretchable member 71 that expands and contracts in the front-to-back direction may be positioned in the center of the width direction W of the rear area S2. The rear-stretchable member 71 only needs to be positioned in the rear area S2 and may span across the crotch area S3. In this embodiment, the rear-stretchable member 71 is positioned spanning across the rear area S2 and the crotch area S3. The rear-stretchable member 71 is made of a member that can expand and contract in the front-to-back direction L, for example, a thread elastic or a flat elastic. In this embodiment, the rear-stretchable member 71 is made of a flat elastic having a predetermined width (for example, 2 mm or more and 5 mm or less) and is joined to the back layer 20.

[0075] The rear stretchable member 71 may be positioned within a certain range (for example, a range of 5 mm to the left and right) that includes the center of the width direction W of the rear area S2, and may straddle the center of the width direction W of the rear area S2. The rear stretchable member 71 can improve the fit to the gap between the left and right buttocks. The rear stretchable member 71 may overlap the surface layer 10 and back layer 20 of the rear area and the crotch area. According to this embodiment, the rear stretchable member 71 can make the surface layer 10 and back layer 20 fit.

[0076] The rear-stretchable member 71 may overlap the containment space S on the non-skin side T2 of the containment space S. According to this embodiment, the stretchable member 71 presses the absorbent pad 100 placed in the containment space S against the skin side T1, thereby suppressing displacement of the absorbent pad 100.

[0077] The front edge 71F of the rear stretchable member 71 may be positioned within the area sandwiched between the left and right leg stretchable members 72. By applying a pulling force to the center of the rear area S2 in the width direction by the rear stretchable member 71, and by pulling and expanding it outward in the width direction by the leg stretchable members 72, it is possible to achieve both a good fit in the center of the rear area S2 in the width direction W and the effect of the leg opening 52 fitting at the lower end of the buttocks without being biased inward in the width direction.

[0078] The front edge 71F of the rear stretchable member 71 is positioned behind the front-to-back center 1CL. The front edge 71F of the rear stretchable member 71 may be positioned in the rear area S2 or in the crotch area S3. Because the front edge 71F of the rear stretchable member 71 is positioned behind the front-to-back center 1CL, the contraction of the rear stretchable member 71 can pull the center of the crotch area S3 in the front-to-back direction L toward the rear.

[0079] The front edge 71F of the rear stretchable member 71 may be positioned behind the rear edge of the insertion opening 68. In this embodiment, the rear edge of the insertion opening 68 is defined by the second crotch side edge portion 612, and the front edge of the insertion opening 68 is defined by the first crotch side edge portion 611. In the region between the rear edge of the insertion opening 68 and the front edge of the stretchable member and the rear edge of the insertion opening, no stretchable member is positioned, and a receiving edge portion 60 is provided, making it difficult for the surface layer 10 and the back layer 20 to wrinkle or crease. Therefore, a good fit to the body can be maintained in that region.

[0080] The front edge 71F of the rear-expandable member 71 may be located behind the rear edge of the narrowest part NW. The narrowest part is less likely to contract due to the rear-expandable member 71, making it easier to maintain a flat shape and easier to attach the absorbent pad.

[0081] (2-8) Leg extension member The shorts 1 may be provided with a pair of leg elastic members 72. The leg elastic members 72 are made of an elastic material, such as elastic thread or flat elastic. In this embodiment, the leg elastic members 72 are made of flat elastic having a predetermined width (for example, 2 mm or more and 5 mm or less) and are joined to the back layer 20 or the outer layer 30. More specifically, the outer parts of the surface layer 10 and the outer parts of the back layer 20 are located outside the outer edge, and only the outer layer 30 is located in the area outside the outer edge in the width direction. In the area where only the outer layer 30 is located, the leg elastic members 72 are joined to the outer layer 30, and in the area where the outer layer 30 and the back layer 20 are located, the leg elastic members 72 may be located on the back layer 20 or the outer layer 30. The leg elastic members 72 are located for each of the left and right leg openings 52.

[0082] The leg elastic member 72 may extend from the outer part of the leg opening 52 in the width direction W to the inner part of the leg opening 52 and be positioned along the leg opening 52. The configuration of extending from the outer part of the leg opening 52 in the width direction W to the inner part of the leg opening 52 in the width direction W is sufficient if, in the pant-type state shown in Figure 1, it extends from a position outside the width direction W of the leg opening 52 (the outer part of the leg opening 52 in the width direction W) to the inner part of the width direction W. Because the leg elastic member 72 is positioned along the leg opening 52, the leg opening 52 fits around the legs and is less likely to shift from the position of the shorts 1 when worn, even when the legs are moved. Therefore, displacement of the surface layer 10 and back layer 20 provided in the crotch area is suppressed, making it easier to keep in contact with the body.

[0083] The inner edge of each leg elastic member 72 may overlap the surface side area R12. That is, the leg elastic member 72 is positioned in the surface side area R12 and does not need to be positioned in the surface central area R11. The leg elastic member 72 can also pull the surface layer 10 in the width direction W, and wrinkles and folds of the surface layer 10 can be suppressed. The surface layer 10 is the layer that comes into direct contact with the skin, and by suppressing wrinkles and folds, discomfort to the skin can be suppressed. In addition, by pulling the surface layer 10 in the width direction W in the area corresponding to the groin, the width of the surface layer 10 can be suppressed, thereby suppressing leakage.

[0084] The inner edge 721 of the leg elastic member 72 may be positioned in front of the front-to-back center 1CL of the shorts, in the main body side area RS. That is, the leg elastic member 72 is not positioned in front of the front-to-back center 1CL of the shorts in the main body central area RC. The main body side area RS is easily positioned outside the center of the thigh in the width direction W. By pulling this main body side area in the width direction W with the leg elastic member 72, wrinkles are less likely to occur when sitting or walking, and the garment can be finished in a way that is less likely to show through clothing.

[0085] The inner edge 721 of each leg elastic member 72 in the width direction W overlaps with the back side region R22. That is, the leg elastic member 72 is positioned in the back side region R22 and not in the back central region R21. Because the leg elastic member 72 extends from the outer part of the leg opening 52 in the width direction W to the inside in the width direction W and overlaps with the back side region R22, the back side regions R22 on both sides of the back layer 20 can be pulled in the width direction W by the leg elastic member 72, causing the back layer 20 to stretch in the width direction W and suppressing wrinkles and folds of the back layer 20. Therefore, the back layer 20 can continue to cover the non-skin side T2 of the surface layer 10, and leakage can be suppressed. Furthermore, in the configuration where the leg elastic member 72 overlaps the central area R21 of the back surface layer 20, the entire width W of the back surface layer 20, including the central area R21, is easily contracted by the leg elastic member 72, creating unevenness on the back surface layer 20 and easily causing discomfort. However, since the leg elastic member 72 does not overlap the central area R21 of the back surface, unevenness caused by the contraction of the leg elastic member 72 can be suppressed. This suppresses discomfort caused by unevenness, and by suppressing gaps between the body and the surface layer 10 and back surface layer 20 caused by unevenness, leakage can be suppressed by keeping them in contact with the body.

[0086] The inner edge 721 of the leg elastic member 72 may overlap the back layer 20 in front of the front-to-back center 1CL of the shorts 1. Since the excretory openings (urinary and vaginal openings) are located towards the front, suppressing wrinkles and twists in the back layer 20 in the front area of ​​the crotch area S3 makes it easier to position the back layer 20 to cover the excretory openings and suppress leakage. Also, the excretory openings are located in the center of the body's width direction W and are easily covered by the back central area R21. Since the inner edge 721 of the leg elastic member 72 overlaps the back side area R22 and does not overlap the back central area R21, the back central area R21 can be pulled to both sides, covering the excretory openings with less wrinkles and twists, thereby improving the fit to the body.

[0087] The leg elastic members 72 may be positioned in front of and behind the front-to-back center 1CL of the shorts. Both the leg elastic member 72 positioned in front of the front-to-back center 1CL and the leg elastic member 72 positioned behind the front-to-back center 1CL may overlap the back layer 20. By pulling the back layer 20 from both the front and back, wrinkles and folds in the back layer can be suppressed. Furthermore, since the leg elastic members 72 are positioned in both the front and back, and each pulls the back layer 20, the back layer 20 is pulled in both the front and back directions, respectively, and wrinkles and folds can be suppressed over the range of the back layer 20 that extends in the front-to-back direction. In addition, the leg opening 52 behind the front-to-back center 1CL is positioned to cover the lower end of the buttocks. By positioning the leg elastic member 72 behind the front-to-back center, displacement of the leg opening 52 is suppressed, making it easier to continue covering the buttocks. Furthermore, by positioning the leg elastic members 72 on both the front and rear sides relative to the front-to-back center, the ratio of the area where the leg elastic members 72 are positioned to the entire circumferential direction of the leg opening 52 increases, thereby further improving the fit around the legs. Therefore, even if the shorts deform due to moving the legs up and down or changing posture, displacement of the leg opening 52 can be suppressed.

[0088] The leg elastic members 72 located in front of the front-to-rear center 1CL and the leg elastic members 72 located behind the front-to-rear center may be connected. According to this embodiment, the leg elastic members 72 located in front of the front-to-rear center and the leg elastic members 72 located in front of the front-to-rear center work together, and both leg elastic members 72 can pull the back surface layer 20 outward in the width direction W.

[0089] The inner edge 721 of the leg elastic member 72 located behind the front-to-back center 1CL may be located further inward in the width direction W than the inner edge 721 of the leg elastic member 72 located in front of the front-to-back center 1CL. On the ventral side, wrinkles can be reduced by positioning the leg elastic member 72 further outward in the width direction W when raising and lowering the legs. On the other hand, on the dorsal side, since it is also necessary to ensure a sense of security that wraps around the buttocks, wrinkles can be reduced by covering the lower edge of the buttocks while also pulling out the area located further inward in the width direction W with the leg elastic member 72.

[0090] The surface layer 10 and the back layer 20 may be positioned in the crotch area S3 and the front area S1. That is, the surface layer 10 and the back layer 20 may be positioned in front of the leg opening 52. Because the surface layer 10 and the back layer 20 are positioned in the crotch area S3 and the front area S1, it is easy to obtain the effect of absorbing bodily fluids in the front area S1. The maximum width of the surface layer 10 in the front area S1 may be longer than the maximum width of the surface layer 10 in the crotch area S3. The maximum width of the back layer 20 in the front area S1 may be longer than the maximum width of the back layer 20 in the crotch area S3. Because the maximum widths of the surface layer 10 and the back layer 20 are longer in the front area S1 than in the crotch area S3, it is possible to provide a sense of security that bodily fluids can be absorbed or leakage can be suppressed even when lying face down or in other positions where bodily fluids spread to the front.

[0091] The tensile stress of the surface layer 10 and back layer 20 in the region where the leg elastic member 72 does not overlap may be lower than the tensile stress of the surface layer 10 and back layer 20 in the region where the leg elastic member 72 overlaps. Because the tensile stress of the region where the leg elastic member 72 does not overlap is low, when the leg is pulled up by the region where the leg elastic member 72 overlaps, the region where the leg elastic member 72 does not overlap can be stretched, and wrinkles and creases in the region where the leg elastic member 72 does not overlap can be reduced.

[0092] The tensile stress can be measured by the following method. First, a sample to be measured is cut out. In the region where the leg expandable member 72 is placed, the leg expandable member 72, the surface layer 10, and the back layer 20 are all cut out together. The tensile stress of the surface layer 10 and the back layer 20 in the region overlapping with the leg expandable member 72 is measured using a sample in which the leg expandable member 72, the surface layer 10, and the back layer 20 are overlapped. In the region where the leg expandable member 72 is not placed, the surface layer 10 and the back layer 20 are all cut out together, and the tensile stress of the surface layer 10 and the back layer 20 in the region not overlapping with the leg expandable member 72 is measured using a sample in which the surface layer 10 and the back layer 20 are overlapped. An autograph-type tensile testing machine (e.g., AG-1KN1) manufactured by Shimadzu Corporation is used to measure the tensile stress. Next, one end of each sample is clamped in a fixed chuck and the other end in a movable chuck. The sample is then stretched at a speed of 100 mm / min to approximately 90% of its initial size, and then reversed to shrink each sample to approximately 75% of its initial size. The tensile load (N) at this point is determined and converted to stress per unit width (mm) (N / mm) to obtain the tensile stress.

[0093] The surface layer 10 and the back layer 20 may be positioned in the crotch area S3 and the rear area S2. That is, the surface layer 10 and the back layer 20 may be positioned beyond the leg opening 52 to the rear. Because the surface layer 10 and the back layer 20 are positioned in the crotch area S3 and the rear area S2, a sense of security regarding leakage can be provided. The maximum width of the surface layer 10 in the rear area S2 may be longer than the maximum width of the surface layer 10 in the crotch area S3. The maximum width of the back layer 20 in the rear area S2 may be longer than the maximum width of the back layer 20 in the crotch area S3. Because the maximum widths of the surface layer 10 and the back layer 20 are longer in the rear area S2 than in the crotch area S3, a sense of security can be provided that bodily fluids can be absorbed or leakage can be suppressed even in positions where bodily fluids are directed to the rear, such as when lying down.

[0094] (2-9) Elastic waistband The shorts 1 may have a waist elastic member 73 positioned along the waist opening 51 and stretching in the width direction W. The waist elastic member 73 may be composed of a plurality of elastic threads, flat elastic, and an elastic sheet. The waist elastic member 73 may overlap the surface layer 10 and the back layer 20. The waist elastic member 73 may overlap the surface layer 10 and the back layer 20 in the front area S1, or it may overlap the surface layer 10 and the back layer 20 in the rear area S2. According to this embodiment, the waist elastic member 73 can make the back layer 20 and the surface layer 10 fit around the waist, and can suppress displacement of the surface layer 10 and the back layer 20 in the front-to-back direction L. Furthermore, in a configuration where the surface layer 10 overlaps both the leg elastic member and the waist elastic member 73, the surface layer 10 fits around the waist around the waist opening 51 and is pulled outward in the width direction W around the leg opening 52, making it easier to maintain a close fit to the body while suppressing wrinkles and twists. The waist elastic member 73 may also overlap the back layer 20, similar to the surface layer 10. The waist elastic member 73 may overlap the back layer 20 in the front area S1, or it may overlap the back layer 20 in the rear area S2.

[0095] (2-10) Narrowest part of the crotch area The shorts 1 may have a narrowest point NW where the width W of the crotch area S3 is shortest. The narrowest point NW includes not only the point where the width W of the crotch area S3 is shortest, but also the portion where the difference in length from the width W at that point is up to 5 mm. This is because the material (fabric, etc.) that makes up the shorts 1 is prone to wrinkles and other issues, and therefore prone to errors. The narrowest point NW may include a certain range extending in the front-to-back direction L. Furthermore, in a form having multiple separable layers (for example, a surface layer and a back layer), as in this embodiment, the narrowest point NW is defined with reference to the outer edge of the material located furthest out in the width direction. Specifically, in the region where the extension portion 15 is provided, the width of the crotch area S3 is measured with reference to the outer edge of the surface layer 10, and in the region where the back layer 20 extends further outward in the width direction W than the surface layer 10, the width of the crotch area is measured with reference to the outer edge of the back layer 20.

[0096] In its natural state, the narrowest part NW of the crotch area S3 may be located at the front-to-back center 1CL. Figure 10 is a schematic diagram showing the crotch area of ​​the shorts 1 as viewed from below when worn. BL in Figure 10 schematically shows the thigh line. The narrowest part of the crotch (the narrowest part of the area sandwiched by the inner thighs) BNW is easily located at the boundary between the ventral and dorsal sides of the body, i.e., the front-to-back center 1CL of the shorts 1. In this embodiment, the narrowest part NW of the crotch area S3 of the shorts 1 is located at the front-to-back center 1CL of the shorts 1 in its natural state (when the rear elastic member 71 is contracted), and the front-to-back position L of the narrowest part NW of the crotch area S3 and the narrowest part BNW of the body align, so the narrowest part NW of the crotch area can be aligned with the narrowest part BNW of the body simply by pulling up the shorts 1. Therefore, it reduces snagging when pulling up shorts 1 and makes it easier to pull up the crotch area S3 to the appropriate position.

[0097] Furthermore, the rear elastic member 71 allows the shorts 1 to be pulled and lifted towards the rear, thus pulling the crotch area S3 towards the rear and widening the leg opening while lifting. This suppresses contact between the shorts 1 and the area extending forward from the inner end of the thigh, allowing the crotch area S3 to be positioned appropriately. In addition, once the shorts 1 have been lifted, the rear elastic member 71, located in the center of the width direction W of the rear area S2, allows the rear area S2 to fit into the gap between the left and right buttocks, suppressing shifting during wear. Moreover, in shorts where the narrowest part NW of the crotch area is located in front of the front-to-back center of the shorts, if the absorbent pad is attached based on the narrowest part NW of the crotch area, the absorbent pad may be positioned too far forward. However, since the narrowest part NW of the crotch area is located at the front-to-back center, it is easy to position the front-to-back center of the crotch area of ​​the absorbent pad at the front-to-back center of the shorts, making it easier to position the absorbent pad appropriately.

[0098] In the stretched state of the shorts 1, the narrowest part NW of the crotch area S3 may be positioned at the front-to-back center 1CL of the shorts 1. When the wearer pulls up the shorts 1, they grasp the left and right ends of the waist opening 51 of the shorts with their left and right hands, respectively, and pull them up while stretching them in the width direction W. As a result, the shorts 1 gradually stretch from their natural state. In the stretched state, the narrowest part NW of the crotch area S3 is located at the front-to-back center 1CL of the shorts 1. Therefore, even in the stretched state when pulled up, the front-to-back position of the narrowest part NW of the crotch area S3 and the front-to-back position of the narrowest part of the body align, suppressing snagging when pulling up the shorts and making it easier to pull up the crotch area S3 to the appropriate position.

[0099] The narrowest part NW may be continuous between the front-to-back center in the natural state and the front-to-back center in the stretched state. According to this embodiment, since the narrowest part NW is continuous between the front-to-back center in the natural state and the front-to-back center in the stretched state, the narrowest part NW of the crotch area S3 is likely to continue to make contact with the narrowest part of the crotch from the natural state when pulling up begins to the stretched state when pulling up is completed. Therefore, snagging when pulling up the shorts 1 is suppressed and the crotch area S3 is made easier to pull up to the appropriate position. In addition, since the narrowest part NW of the crotch area S3 has a certain length in the front-to-back direction L, even if the shorts 1 shifts in the front-to-back direction L due to changes in posture etc. when wearing, it is easy to keep the front-to-back position of the narrowest part NW of the crotch area S3 and the narrowest part of the body aligned. Therefore, the rear stretchable member 71 makes it easy to keep the rear area S2 fitted into the gap between the left and right buttocks, and the shifting of the entire shorts 1 can be suppressed. The length in the front-to-back direction of the narrowest part NW of the crotch area is, for example, 10 mm or more, and preferably 20 mm or more. Alternatively, the length in the front-to-back direction of the narrowest part NW of the crotch area may be 140 mm or less.

[0100] The narrowest part NW of the crotch area S3 may be continuous in the front-to-back direction L and positioned across the front-to-back center in a natural state. According to this embodiment, since the narrowest part NW of the crotch area S3 has a certain length in the front-to-back direction L, even if the shorts 1 shift in the front-to-back direction L due to changes in posture during wear, it is easy to keep the front-to-back position of the narrowest part NW of the crotch area S3 aligned with the narrowest part of the body. Therefore, the rear elastic member 71 makes it easy to keep the rear area S2 fitted into the gap between the left and right buttocks, and the shifting of the entire shorts 1 can be suppressed.

[0101] In its natural state, the length L in the anterior-posterior direction of the narrowest part NW located in front of the anterior-posterior center 1CL may be longer than the length L in the anterior-posterior direction of the narrowest part NW located behind the anterior-posterior center 1CL. Generally, the range of motion of the legs during walking is wider in the area in front of the anterior-posterior center 1CL than in the area behind it. A longer anterior-posterior length of the narrowest part NW located in front of the anterior-posterior center 1CL makes it easier to move the legs. In addition, it can suppress the pulling of the shorts 1 in the anterior-posterior direction when the legs are moved, suppress the displacement of the shorts 1, and make it easier to keep the crotch area in contact with the body. The anterior-posterior length of the narrowest part NW located in front of the anterior-posterior center may be 20 mm or more and 130 mm or less, and the anterior-posterior length of the narrowest part NW located behind the anterior-posterior center 1CL may be 5 mm or more and less than 20 mm.

[0102] The extension portion 15 may be provided at the narrowest portion NW. In a configuration where the narrowest portion NW has a certain range in the front-to-back direction, it is sufficient for the extension portion 15 to be provided on at least a part of the narrowest portion NW. According to this embodiment, because the extension portion 15 is provided, the user can easily understand that two layers, the surface layer 10 and the back layer 20, are arranged and that an absorbent pad can be inserted between them. Therefore, the operation of attaching the absorbent pad can be performed smoothly. In addition, because the extension portion is provided at the narrowest portion NW, there is no leg elastic member 72, etc., and the extension portion is provided at the narrowest portion, which is relatively unaffected by stretching and shrinking, making it easier to maintain the shape of the extension portion and making it easier for the wearer to notice the extension portion.

[0103] (2-11) Elongation The elongation of the back layer 20 may be higher than that of the surface layer 10. In this embodiment, because the elongation of the back layer 20 is relatively high, after inserting the wing 105 with a gap between the surface layer 10 and the back layer 20, the back layer 20 can press the surface layer 10 and the absorbent pad 100 against the body, thereby improving the fit to the body. In addition, at the narrowest part NW of the crotch area S3, the surface layer 10 and the back layer 20 may be spaced apart. In this embodiment, even at the narrowest part NW where the elongation of the surface layer 10 is low and the width is narrow, the width of the surface layer 10 can be secured, making it easier to keep the surface layer 10 in contact with the excretory opening. On the other hand, because the elongation of the back layer 20 is high, the back layer 20 can press the surface layer 10 against the body, improving the fit to the body. Furthermore, because the surface layer 10 and the back layer 20 are separated at the narrowest part NW of the crotch area S3, the expansion and contraction of the back layer 20 prevents the surface layer 10 from widening, ensuring the width of the surface layer 10 and making it easier to keep the surface layer 10 in contact with the excretory opening.

[0104] Here, elongation can be measured by the following method, and the level of elongation can be evaluated based on the numerical value. The measurement is performed using a tensile testing machine manufactured by Instron Japan Company Limited. The distance between the upper and lower hooks of the tensile testing machine is adjusted to a predetermined length, and the sample is attached to the upper hook (fixed) and lower hook (movable). The tensile testing machine is moved at a tensile speed of 100 mm / min, and the maximum stress until 120% elongation is measured.

[0105] (2-12) Visibility of the shorts from the outside When the shorts 1 are viewed from the front in their natural state, the surface layer located behind the front-to-back center 1CL is visible from the front. That is, in the natural state of the shorts, at least a portion of the surface layer 10 located behind the front-to-back center 1CL may be exposed and not covered by the front area S1. When putting on the shorts 1, the wearer can see the skin-facing surface of the front area S1 and the skin-facing surface of the crotch area S3, and can understand the position of the surface layer 10 in the front area S1 and the crotch area S3. Furthermore, according to this embodiment, the wearer can see the surface layer 10 of the rear area S2 before putting on the shorts. Since the position of the surface layer 10 can be understood in any of the areas of the front area S1, rear area S2, and crotch area S3, it is easy to position the surface layer 10 appropriately. In addition, in the form in which the surface layer 10 functions as an absorbent layer that absorbs bodily fluids, the wearer can recognize that the surface layer that absorbs bodily fluids is located over a wide area, and can easily gain a sense of security regarding the absorbent performance.

[0106] In the natural state of the shorts 1, when viewed from the front, the insertion opening 68 located behind the front-to-back center 1CL of the shorts may be visible from the front. That is, in the natural state of the shorts, the insertion opening 68 located behind the front-to-back center 1CL may not be covered by the front area S1 and may be exposed. According to this embodiment, the wearer can see the insertion opening 68 in the rear area S2 before putting on the shorts, so they can understand where to insert the absorbent pad 100 and easily perform the putting-on operation.

[0107] In a natural state, when the shorts are viewed from the front, the surface layer 10 adjacent to the insertion opening located behind the front-to-back center 1CL of the shorts may be visible from the front. According to this embodiment, the wearer can see the surface layer 10 constituting the insertion opening 68 in the rear area S2 before putting on the shorts, so they can understand where to insert the absorbent pad 100 and easily perform the putting-on operation.

[0108] When viewing the shorts 1 in their natural state from the front, the surface layer 10 adjacent to the insertion opening 68 located in front of the front-to-back center 1CL of the shorts may be visible. That is, an extension may be provided adjacent to the insertion opening located in front of the front-to-back center 1CL of the shorts. According to this embodiment, the wearer can see both the surface layer 10 constituting the insertion opening in the rear area and the surface layer 10 constituting the insertion opening 68 in the front area S1 before putting them on, so that they can grasp the position to insert the absorbent pad 100 and easily perform the putting operation.

[0109] The colors of the surface layer 10 and the back layer 20 may be different. According to this embodiment, the surface layer 10 and the back layer 20 can be distinguished by sight, making it easier to recognize the extent of the surface layer 10. Also, the ability to distinguish the surface layer 10 and the back layer 20 by sight makes it easier for the wearer to grasp the position of the insertion opening, and makes it easier to insert the wing 105, etc., between the surface layer 10 and the back layer 20. The colors of the surface layer 10 and the outer layer 30 may also be different. According to this embodiment, the surface layer 10 and the outer layer 30 can be distinguished by sight, making it easier to recognize the extent of the surface layer 10. In this invention, configurations with different colors are configurations with a color difference ΔE of 3.0 or more, and configurations with the same colors are configurations with a color difference ΔE of less than 3.0. The color difference ΔE can be determined by measuring the color of two points (two regions) to be measured using a commercially available colorimeter and comparing the numerical values ​​based on the CIE1976 (L*a*b*) color space specified in JIS Z 8781. Specifically, when the difference in L* values ​​between two points being measured is ΔL*, the difference in a* is Δa*, and the difference in b* values ​​is Δb*, then the color difference ΔE = [(ΔL*) 2 +(Δa*) 2 +(Δb*) 2 ] 1 / 2 This is determined by [the specified method]. In addition, in the modified example, the color of the surface layer 10 and the color of the back layer 20 may be the same. According to this embodiment, the surface layer 10 and the back layer 20 are integrated, the extended portion 15 is less noticeable, and the wearer can use it without being aware of the extended portion 15.

[0110] (2-13) Seams of the surface layer and back layer The surface layer 10 and the back layer 20 may be constructed by laminating multiple materials (for example, fabric). The laminated materials may be a single folded material or multiple materials may be stacked on top of each other. As shown in Figure 7(D), in the crotch area S3, the material constituting the back layer 20 may be folded inward in the width direction W, starting from the back fold FL20 located on the outer side of the crotch area S3. The material constituting the outer layer 30 may be folded inward in the width direction W, starting from the outer fold FL30 located on the outer side of the crotch area S3. The folded portion of the back layer 20 and the folded portion of the outer layer 30 are joined by a seam ST. In the crotch area S3, the material constituting the surface layer 10 is made up of two laminated pieces, each folded inward in the width direction W, starting from the surface fold FL10 located on the outer side of the crotch area S3. The folded portions of the surface layer 10 are positioned opposite each other and joined by seams ST. In the crotch area S3, the seams ST of the materials in the back layer 20 and the seams ST of the materials in the surface layer 10 are not exposed on the skin-facing and non-skin-facing surfaces of the shorts, and may be positioned inside the skin-facing and non-skin-facing surfaces of the shorts. For example, after sewing multiple materials together, the seams ST can be positioned on the inside by folding them back so that the seams ST are on the inside.

[0111] According to this embodiment, the seams ST of the material in the surface layer 10 and the seams ST of the material in the back layer 20 are less likely to come into contact with the legs, thus reducing discomfort caused by seams coming into contact with the legs. Furthermore, since the surface fold FL10 and the back fold are located on the outer side of the crotch area, there are areas on the outer side of the crotch area where the material of the surface layer 10 overlaps and areas where the material of the back layer 20 overlaps. The large amount of material on the outer side of the crotch area suppresses lateral leakage and provides a sense of security against lateral leakage.

[0112] Furthermore, as shown in Figures 7(A) and (B), in the region where the leg elastic member 72 is placed, the back layer 20 and the outer layer 30 may both be folded, and the leg elastic member 72 may be placed between the folded back layers 20. In the region where the leg elastic member 72 is placed, the leg elastic member 72, the surface layer 10, the back layer 20, and the outer layer 30 are joined by a seam ST, and this seam may be placed on the skin-facing and non-skin-facing surfaces of the shorts. As shown in Figure 7(C), in the region away from the leg opening 52, the surface layer 10 and the back layer 20 may not be folded, but instead be joined by a seam ST. This seam may be placed on the skin-facing and non-skin-facing surfaces of the shorts.

[0113] (3) Shorts relating to the modified form Next, the receiving edge 60 according to the modified example will be described with reference to Figure 11. In the description of the modified example, the same reference numerals will be used for components similar to those in the above-described embodiment, and their description will be omitted. Figure 11(A) shows shorts 1X according to Modified Example 1. The crotch edge 61 according to the embodiment extends linearly from both outer edges in the width direction W of the crotch area S3 toward the inside in the width direction W. In contrast, the crotch edge 61X according to Modified Example 1 has a protruding shape that bulges toward the inside in the width direction. The protruding shape may be curved. The crotch edge 61 according to Modified Example 1 can also suppress displacement of the absorbent pad 100 in the front-rear direction. Figure 11(B) shows shorts 1Y according to Modified Example 2. The crotch edge 61Y according to Modified Example 2 extends linearly from both outer edges in the width direction W of the crotch area S3 toward the inside in the width direction W. The angle α between a line parallel to the width direction and the direction in which the crotch edge extends is smaller than the angle β between the outer edge of the absorbent pad at the position corresponding to the crotch edge and the line parallel to the width direction, and may preferably be an acute angle. According to this embodiment, the absorbent pad is more likely to catch on the crotch edge, and the absorbent pad is less likely to slip.
