[0005] Patent Document 1: Japanese Patent Application Publication No. 2020-59942 Summary of the Invention

[0006] According to this design, by reducing the recovery stress in the central abdominal area and increasing the recovery stress in the iliac region, excessive constriction relative to the wearer's abdomen can be prevented, and the overall shifting and slipping of the shorts can be suppressed. However, the applicant conducted an in-depth study on the wearing conditions of the shorts, and the results showed that the wearer's waist size and circumference change with body postures such as sitting and standing. The amount of change in waist size and circumference varies depending on body type. If the change in waist size and circumference is large, the abdomen will shift and slip, or the lower part of the buttocks will be exposed from the shorts due to the pull of the abdomen, making it impossible to continuously cover the abdomen and buttocks with the shorts. In particular, it was found that the abdominal circumference of middle-aged women is larger than that of younger women. Furthermore, it was found that, depending on posture, such as standing and sitting, the abdominal circumference changes by about 3cm to 5cm, making it difficult to continuously cover the abdomen and buttocks with the shorts.

[0007] The present invention was made in view of the following problem, and its object is to provide shorts that can easily and continuously cover the body even if the waist size and waist circumference change due to changes in body posture.

[0008] One design of shorts includes a front panel that contacts the wearer's abdomen and a back panel that contacts the wearer's back. In the shape of underwear with a waist opening and a pair of leg openings, it has a longitudinal direction along the wearer's height and a transverse direction orthogonal to the longitudinal direction. The front panel includes: a front waist region extending inward from the waist opening towards the longitudinal direction; a front crotch region extending outward from the longitudinal boundary (i.e., the longitudinal boundary) of the front and back panels, beyond the leg openings; and a front center region located between the front waist region and the front crotch region. The 1.3 times tensile strength in the front center region is higher than the 1.3 times tensile strength in the front waist region.

[0009] Another type of shorts has a front panel that contacts the wearer's abdomen and a back panel that contacts the wearer's back. In the shape of underwear with a waist opening and a pair of leg openings, it has a longitudinal direction along the wearer's height and a transverse direction orthogonal to the longitudinal direction. The front panel has: a front waist region extending inward from the waist opening towards the longitudinal direction; a front crotch region extending outward from the longitudinal boundary (i.e., the longitudinal boundary) of the front and back panels, crossing the leg openings; and a front center region located between the front waist region and the front crotch region. In the natural state of the shorts, the maximum transverse length of the front center region is shorter than the maximum transverse length of the front waist region and shorter than the maximum transverse length of the front crotch region.

Detailed Implementation

[0021] (1) Overview of the implementation method

[0022] Based on the description in this specification and the accompanying drawings, at least the following matters become clear.

[0023] The invention of method 1 has a front panel that contacts the wearer's abdomen and a back panel that contacts the wearer's back. For shorts, in the shape of underwear forming a waist opening and a pair of leg openings, there is a longitudinal direction along the wearer's height direction and a transverse direction orthogonal to the longitudinal direction. The front panel has: a front waist region extending inward from the waist opening toward the longitudinal direction; a front crotch region extending outward from the boundary of the longitudinal direction between the front and back panels, i.e., the longitudinal boundary, across the leg openings; and a front center region located between the front waist region and the front crotch region. The 1.3 times tensile strength in the front center region is higher than the 1.3 times tensile strength in the front waist region.

[0024] When wearing shorts with the front panel covering the abdomen, the front waist area covers the area around the navel, and the front crotch area covers the groin area. The front center area is closer to the crotch and higher than the groin area, making it easy to cover the iliac crest. When wearing shorts, they are stretched naturally, fitting the body with approximately 1.3 times the normal stretch. The wearer does not feel pressure at the iliac crest, thus allowing for a greater 1.3 times stretch in the front center area covering the iliac crest, suppressing discomfort and maintaining the shorts' shape relative to the iliac crest. The front waist area, located above the front center area, has a smaller 1.3 times stretch than the front center area, allowing it to adapt to changes in waist size and circumference while suppressing pressure. It easily and consistently covers the bulge of the abdomen and suppresses unevenness at the waistline.

[0025] According to a preferred embodiment, the invention of embodiment 1, in embodiment 2, has the following features: It has a front panel that contacts the wearer's abdomen and a back panel that contacts the wearer's back. For the shorts, in the shape of underwear forming a waist opening and a pair of leg openings, it has a longitudinal direction along the wearer's height direction and a transverse direction orthogonal to the longitudinal direction. The front panel has: a front waist region extending inward from the waist opening towards the longitudinal direction; a front crotch region extending outward from the boundary of the longitudinal direction between the front and back panels, i.e., the longitudinal boundary, across the leg openings; and a front center region located between the front waist region and the front crotch region. In the natural state of the shorts, the maximum transverse length of the front center region is shorter than the maximum transverse length of the front waist region and shorter than the maximum transverse length of the front crotch region.

[0026] When wearing shorts to cover the bulge of the abdomen using the front panel, the front waist area covers the area around the navel, and the front crotch area covers the groin area. The front center area is closer to the crotch and higher than the groin area than the area around the navel, making it easy to cover the iliac crest. The wearer doesn't feel pressure at the iliac crest, so the maximum length of the front center area covering the iliac crest is shorter, which can suppress discomfort and keep the shorts in place relative to the iliac crest. The front waist area above the front center area is naturally longer than the front center area, so it easily and consistently covers the bulge of the abdomen without compressing it, even if the wearer's waist size changes. The front crotch area on the crotch side of the front center area is naturally longer than the front center area, so it easily and consistently covers the body even if the waist size changes.

[0027] According to a preferred embodiment, the invention of embodiment 2, in embodiment 3, has the following features: The 1.3 times tensile force in the front middle region is lower than the 1.3 times tensile force in the front waist region. In its natural state, the front middle region, with its shorter maximum length in the lateral direction, most elongates and conforms to the body. During the stretching process to 1.3 times the wearing length, the tensile stress in the front middle region is lower, so even if the waist size changes, it can stretch without excessively constricting the body during wear. Furthermore, regarding the front waist region, since its natural lateral length is longer, it conforms gently and less elongated relative to the wearer's waist size. Even if the waist size lengthens during the stretching process to 1.3 times the wearing length, it can continuously cover the bulge of the abdomen without compressing the abdomen.

[0028] According to a preferred embodiment, for the invention of embodiment 4, in any of embodiments 1 to 3, the invention has the following features: The back panel has: a back waist region connected to the front waist region via the lateral boundaries of the front and back panels, and extending from one lateral boundary to the other; a back crotch side region extending outward in the longitudinal direction from the longitudinal boundary across the leg opening; and a back center region located between the back waist region and the back crotch side region, extending from one lateral boundary to the other. In the natural state of the shorts, the maximum lateral length of the back center region is shorter than the maximum lateral length of the back waist region and shorter than the maximum lateral length of the back crotch side region. According to this embodiment, since the front center region and the back center region, which have relatively short lateral lengths, are connected, the shorts can be maintained by using the front center region and the back center region to surround the waist. It is easy to use the front and back center areas to fit the waist, and easy to use the upper waist area and the crotch side area to continuously cover the body.

[0029] According to a preferred embodiment, for the invention of embodiment 5, in any of embodiments 1 to 4, the invention has the following feature: The front middle region curves from the side portion of the front panel in the lateral direction toward the center of the front panel in the lateral direction toward the crotch side. According to this embodiment, the front middle region can be easily positioned at the pelvic position connecting the pubic symphysis and the anterior superior iliac spine. Since the pelvic position connecting the pubic symphysis and the anterior superior iliac spine is a position where the wearer is less likely to feel pressure, it is easier to suppress discomfort and maintain the overall position of the shorts, and it is easier to continuously cover the body even with changes in body posture.

[0030] According to a preferred embodiment, for the invention of embodiment 6, in any of embodiments 1 to 5, the invention has the following features. The rear body panel has: a rear waist region connected to the front waist region via the lateral boundaries of the front and rear body panels, and extending from one lateral boundary to the other; a rear crotch side region extending outward in the longitudinal direction from the longitudinal boundary across the leg opening; and a rear middle region located between the rear waist region and the rear crotch side region, extending from one lateral boundary to the other. The longitudinal bending stiffness of the rear waist region is higher than that of the front waist region. The front waist region has lower longitudinal bending stiffness and is prone to wrinkling when the longitudinal dimensions of the abdomen change due to posture variations. The rear waist region has higher longitudinal bending stiffness, allowing it to support the ends of the front waist region at the sides where longitudinal dimensional changes are less pronounced. It can reduce wrinkling in the front waist area, and it can also make wrinkles easier to flatten when they occur in the front waist area.

[0031] According to a preferred embodiment, for the invention of embodiment 7, in any of embodiments 1 to 6, the invention has the following features: The back panel has: a back waist region connected to the front waist region via the lateral boundaries of the front and back panels, and extending from one lateral boundary to the other; a back crotch region extending outward in the longitudinal direction from the longitudinal boundary across the leg opening; and a back center region located between the back waist region and the back crotch region, extending from one lateral boundary to the other. The front center region and the back center region are constructed of a continuous tubular fabric in the lateral direction. Continuous tubular elastic threads in the lateral direction are arranged on the tubular fabric. According to this embodiment, since the front center region and the back center region are constructed of continuous tubular fabric, tension is easily applied to the front and back panels, thus maintaining a close fit relative to the body. In addition, since the elastic band is also cylindrical, it is not easy for the elastic band to fall off, thus making it easier to maintain the tensile force in the middle area.

[0032] According to a preferred embodiment, for the invention of embodiment 8, in any of embodiments 1 to 7, the invention has the following feature: In the natural state of the shorts, the waist opening of the front panel extends outward in the longitudinal direction than the waist opening of the back panel. According to this embodiment, it is easy to utilize the front panel to ensure coverage of the bulge of the abdomen, and it is easy to maintain continuous coverage of the abdomen.

[0033] According to a preferred embodiment, for the invention of embodiment 9, in any one of embodiments 1 to 8, it has the following features. The rear body panel has: a rear waist region connected to the front waist region via the lateral boundaries of the front and rear body panels, and extending from one lateral boundary to another; a rear crotch side region extending outward in the longitudinal direction from the longitudinal boundary across the leg opening; and a rear middle region located between the rear waist region and the rear crotch side region, extending from one lateral boundary to another. The front crotch side region has a front leg region adjacent to the leg opening and a front lower crotch region located between the front middle region and the front leg region. The rear crotch side region has a rear leg region adjacent to the leg opening and a rear lower crotch region located between the rear middle region and the rear leg region. A high-tension section is provided in the front leg area, in which the stretching force in the leg circumference direction surrounding the wearer's leg is higher than that in the front crotch area. A high-tension section is provided in the rear leg area, in which the stretching force in the leg circumference direction is higher than that in the rear crotch area. One end of the high-tension section in the leg circumference direction is connected to the high-tension section in the rear, and the other end of the high-tension section in the leg circumference direction is connected to the front middle area. According to this method, due to the high-tension section in the rear, the hip boundary relative to the leg opening of the back panel can be stably covered, and the hip can be completely covered. Even in body types where the boundary between the hip and the upper thigh is not obvious, it is easy to prevent the shorts from shifting and to continuously cover the body. In addition, since one end of the high-tension section in the leg circumference direction is connected to the high-tension section in the rear, and the other end of the high-tension section in the leg circumference direction is connected to the front middle area, it is easy to prevent the leg area from shifting and slipping, and even in body types where the boundary between the hip and the upper thigh is not obvious, it is easy to lift the shorts and to continuously cover the body.

[0034] According to a preferred embodiment, for the invention of embodiment 10, any one of embodiments 1 to 9 has the following features: A first crotch-side member is disposed in the crotch-side region, extending between one lateral boundary and the other; and a pair of second crotch-side members are disposed overlapping the first crotch-side member and extend inward from each lateral boundary toward the lateral direction. The first crotch-side member in the foreleg region and the second crotch-side member in the foreleg region are stacked together in a non-engaged state. According to this embodiment, the first crotch-side member in the foreleg region and the second crotch-side member in the foreleg region are stacked together in a non-engaged state, so their relative positions change according to leg movement, easily following the body. Therefore, it is easy to suppress the situation where the leg opening is pulled toward the abdomen due to leg movement, and it is easy to continuously cover the lower end of the buttocks and the bulge of the buttocks.

[0035] According to a preferred embodiment, for the invention of embodiment 11, in any one of embodiments 1 to 10, the following feature is included: the longitudinal length of the front middle region at the lateral boundary is shorter than the longitudinal length of the front crotch side region at the lateral boundary, and shorter than the longitudinal length of the front waist region at the lateral boundary. According to this embodiment, by preventing the longitudinal length of the front middle region relative to the body from becoming excessively long, the shorts are kept in place while suppressing a feeling of pressure on the body, and by ensuring the longitudinal length of the front waist region and the front crotch side region, it is easy to continuously cover the abdomen and buttocks.

[0036] According to a preferred embodiment, the invention of embodiment 12, in any one of embodiments 1 to 11, has the following features: The shorts have a crotch member disposed in the crotch of the wearer. The crotch member has: an absorbent layer that absorbs bodily fluids; a low-water-retention layer that covers the skin-side surface of the absorbent layer and has lower water-retention than the absorbent layer; and a low-permeability layer that covers the non-skin-side surface of the absorbent layer and has lower permeability than the absorbent layer. The shorts are reusable absorbent shorts.

[0037] According to a preferred embodiment, the invention of embodiment 13, in any one of embodiments 1 to 12, has the following features: The area of ​​the joint formed by the bonding of the absorbent layer and the low-permeability layer is 20% or less relative to the overlapping area of ​​the absorbent layer and the low-permeability layer. The absorbent layer and the low-permeability layer are laminated together in a non-bonded state. According to this embodiment, bodily fluids guided to the low-permeability layer are transferred to the absorbent layer located on the non-skin side and retained by the absorbent layer. Because of the joint, the absorbent layer and the low-permeability layer are closely adhered, and the increased density in the joint allows for smooth transfer of bodily fluids to the absorbent layer side. Furthermore, because the area ratio of the joint is as low as 20% or less, the absorbent layer and the low-permeability layer are easily separated, improving breathability when worn and facilitating drying in reusable shorts.

[0038] (2) Shorts of the implementation method

[0039] Hereinafter, the embodiment of the shorts 1 will be described with reference to the accompanying drawings. Furthermore, in the following description of the drawings, the same or similar reference numerals will be used to label the same or similar parts. However, it should be noted that the drawings are schematic diagrams, and the proportions of the dimensions may differ from reality. Therefore, specific dimensions should be determined by referring to the following description. Additionally, the drawings may contain parts with different dimensional relationships or proportions. The shorts 1 are women's shorts, particularly shorts for middle-aged women.

[0040] The shorts 1 in this embodiment include the shorts 1A of the first embodiment and the shorts 1B of the second embodiment. Figures 1-4 This is a diagram of the shorts 1A according to the first embodiment. Figure 1 This is a top view of the natural state as seen from the ventral side.

Figures 5-9 This is a diagram of the shorts 1B according to the second embodiment. Figure 5 This is a top view of the natural state as seen from the ventral side. Figure 6 This is a top view of the natural state as observed from the rear. Figure 7 This is a diagram showing the components that constitute the shorts 1B of the second embodiment. Figure 8 This is a diagram used to explain the wearing state of the shorts 1B in the second embodiment, and it shows the wearing state as viewed from the side. Figure 8 (A) represents the standing position. Figure 8 (B) is the sitting position. Figure 9 This is a diagram showing the measurement results of the tensile force in each region of the shorts according to the second embodiment. Furthermore, in the following description, the common structure in the shorts 1A of the first embodiment and the shorts 1B of the second embodiment is described as the description of shorts 1. Additionally, "natural state" refers to the state when the shorts 1 has been placed for a predetermined time. For example, after the shorts are stretched to the left and right sides for 15 seconds, the stretch is released and the shorts 1 are placed on a flat surface such as a table. Then, the state after 5 minutes of this flat surface is defined as the natural state.

[0041] The shorts 1, in the shape of underwear with a waist opening 51 and a pair of leg openings 52, has a longitudinal direction X along the wearer's height direction, a transverse direction Y orthogonal to the longitudinal direction X, and a thickness direction. The thickness direction extends along the skin side (inner side) facing the wearer and the non-skin side (outer side) facing the opposite side of the wearer. The planar direction of the shorts 1 includes both the longitudinal direction X and the transverse direction Y. The waist opening 51 is surrounded by the front edge of the front panel 10 and the rear end of the back panel 20, serving as an opening for the wearer's waist to be inserted. The pair of leg openings 52 are separately arranged in the transverse direction Y, serving as openings for the wearer's legs to be inserted.

[0042] The shorts 1 have a front panel 10 that contacts the wearer's abdomen and a back panel 20 that contacts the wearer's back. The front panel 10 is the part that contacts the wearer's abdomen. Figure 1 The middle section is positioned on the front side. The back panel 20 is the part that contacts the wearer's back. Figure 2 The front panel 10 and the back panel 20 are positioned on the front side. The front panel 10 and the back panel 20 are adjacent in the lateral direction Y. The boundary between the front panel 10 and the back panel 20 in the lateral direction Y, also known as the lateral boundary BY, is located at both ends of the shorts 1 in the lateral direction Y. The front panel 10 and the back panel 20 are adjacent in the longitudinal direction X. The boundary between the front panel 10 and the back panel 20 in the longitudinal direction X, also known as the longitudinal boundary BX, is located adjacent to the inner end of the front panel 10 in the longitudinal direction X and the inner end of the back panel 20 in the longitudinal direction X.

[0043] Furthermore, the front panel 10 and the rear panel 20 can be composed of different components or the same components. For example... Figure 7As shown, the components constituting the shorts 1 of this embodiment include components that constitute only the front panel 10, components that constitute only the back panel 20, and components that constitute both the front panel 10 and the back panel 20. The components constituting the shorts can be made of fabric, and there are no particular limitations on the material. For example, fabrics containing at least any one of cotton, cellulosic fibers, wool, polyester, nylon, and polyurethane can be exemplified.

[0044] The front panel 10 has a front waist region F11, a front crotch side region F13, and a front middle region F12. The front waist region F11, the front crotch side region F13, and the front middle region F12 are adjacent regions that divide the front panel 10 in the longitudinal direction X. The front waist region F11 extends inward from the waist opening 51 towards the longitudinal direction X. The front edge (outer edge in the longitudinal direction) of the front waist region F11 is the waist opening 51, and the rear edge (inner edge in the longitudinal direction) of the front waist region F11 is the front edge of the front middle region F12. The front edge of the front middle region F12 is the rear edge of the front waist region F11, and the rear edge of the front middle region F12 is the front edge of the front crotch side region F13. The front waist region F11 and the front middle region F12 extend from one lateral boundary BY to another lateral boundary BY. The outer edge of the front waist region F11 in the lateral direction Y and the outer edge of the front middle region F12 in the lateral direction Y are the lateral boundaries BY.

[0045] In this embodiment, the front middle region F12 is composed of a component different from the front waist region F11 and the front crotch side region F13, and its length in the lateral direction Y under tensile force or in its natural state differs from that of the front waist region F11 and the front crotch side region F13. The boundary between the front middle region F12 and the front waist region F11 can be the boundary of the component or the boundary of the change in length in the lateral direction under tensile force or in its natural state. Similarly, the boundary between the front middle region F12 and the front crotch side region F13 can be the boundary of the component or the boundary of the change in tensile force.

[0046] The crotch side region F13 extends outward from the longitudinal boundary BX in the longitudinal direction X. A leg opening 52 is provided in the crotch side region F13. The front edge of the crotch side region F13 may be the rear edge of the front middle region F12, located outward in the longitudinal direction X compared to the front edge of the leg opening 52. The rear edge of the crotch side region F13 is the longitudinal boundary BX. A leg opening 52 is provided in the crotch side region F13. For the outer edge of the crotch side region F13 in the lateral direction Y, in the region of the crotch side region F13 that is outward in the longitudinal direction X compared to the leg opening 52, the crotch side region F13 extends from one lateral boundary BY to another lateral boundary BY. In the region of the crotch side region F13 that is outward in the longitudinal direction compared to the leg opening 52, the outer edge of the crotch side region F13 in the lateral direction Y is the lateral boundary BY.

[0047] It is possible that the front crotch region F13 has a front leg region F31 adjacent to the leg opening 52, and a front lower crotch region F32 located between the front middle region F12 and the front leg region. The front leg region F31 can be a region extending from the leg opening 52 within a certain range, for example, it can be a range extending from the leg opening 52 to 20 mm. Alternatively, it is possible that, in a manner where the component surrounding the leg opening 52 is composed of components different from those in other regions, the front leg region F31 is configured with a component surrounding the leg opening 52 ( Figure 7 The area of ​​the front lace fabric 321 shown in this embodiment.

[0048] like Figure 7 As shown, the front crotch area F13 of this embodiment is composed of multiple components. The components of the front crotch area F13 include: a first crotch member 131 that extends continuously from one lateral boundary BY to another lateral boundary BY; a pair of second crotch members 132 that are partially overlapped with the first crotch member 131 and extend inward from each lateral boundary BY toward the lateral direction Y; a crotch member 140 that is adjacent to the first crotch member 131 in the longitudinal direction X and is disposed at the wearer's crotch; and a front lace fabric 321. The crotch member 140 spans the front crotch area F13 and the rear crotch area R13. A longitudinal boundary BX is disposed on the crotch member 140.

[0049] The pair of second crotch side members 132 can be adjacent in the transverse direction Y as in the first embodiment, or separated in the transverse direction Y as in the second embodiment. For the second crotch side members 132, their length in the longitudinal direction X decreases from the transverse boundary BY towards the inner side in the transverse direction. A front lace fabric 321 is disposed adjacent to the second crotch side members 132. The front lace fabric 321 is disposed along the leg opening 52 and can form a high-stretch portion as described later. The front lace fabric 321 may be a fabric whose tensile force in the leg circumference direction is higher than that of the second crotch side members 132, whose tensile force in the leg circumference direction is higher than that of the first crotch side members 131, and whose tensile force in the leg circumference direction is higher than that of the crotch member 140. The leg opening 52 is surrounded by the inner edge of the longitudinal direction X of the first crotch side member 131, the inner edge of the longitudinal direction X of the second crotch side member 132, the outer edge of the transverse direction Y of the crotch member 140, and the inner edge of the longitudinal direction X of the third crotch side member 133, which will be described later.

[0050] The rear panel 20 has a rear waist region R11, a rear crotch side region R13, and a rear middle region R12. The rear waist region R11, rear crotch side region R13, and rear middle region R12 are adjacent regions that divide the rear panel 20 in the longitudinal direction X. The rear waist region R11 is connected to the front waist region F11 via a lateral boundary BY. The rear waist region R11 may be connected to at least a portion of the front waist region F11, or to the entire longitudinal direction X region of the front waist region F11, and the longitudinal directions of the rear waist region R11 and the front waist region F11 are of the same extent. The rear waist region R11 extends inward from the waist opening 51 towards the longitudinal direction X. The rear end edge of the rear waist region R11 is the waist opening 51, and the front end edge of the rear waist region R11 is the rear end edge of the rear middle region R12. The rear end edge of the rear middle region R12 is the front end edge of the rear waist region R11, and the front end edge of the rear middle region R12 is the rear end edge of the rear groin region R13. The rear waist region R11 and the rear middle region R12 extend from one lateral boundary BY to another lateral boundary BY. The outer edges of the lateral direction Y of the rear waist region R11 and the outer edges of the lateral direction Y of the rear middle region R12 are lateral boundaries BY.

[0051] In this embodiment, the rear middle region R12 is composed of a component different from the rear waist region R11 and the rear crotch region R13, and its length in the lateral direction under tension or in its natural state differs from that of the rear waist region R11 and the rear crotch region R13. The boundaries of the rear waist region R11 and the rear middle region R12 can be the boundaries of the components or the boundaries of changes in the lateral length under tension or in its natural state. Similarly, the boundaries of the rear middle region R12 and the rear crotch region R13 can be the boundaries of the components or the boundaries of changes in tension. In the case where the front middle region F12 and the rear middle region R12 are composed of components different from those of the waist region, the position of the front middle region F12 in the longitudinal direction X and the position of the rear middle region R12 in the longitudinal direction X may not be completely consistent, or they may be offset in the longitudinal direction X.

[0052] The rear crotch region R13 extends outward from the longitudinal boundary BX in the longitudinal direction X. A leg opening 52 is provided in the rear crotch region R13. The rear end edge of the rear crotch region R13 may be the front end edge of the rear middle region R12, located outward in the longitudinal direction X compared to the rear end edge of the leg opening 52. The front end edge of the rear crotch region R13 is the longitudinal boundary BX. Since the leg opening 52 is provided in the rear crotch region R13, for the outer edge of the rear crotch region R13 in the lateral direction Y, in the region of the rear crotch region R13 that is outward in the longitudinal direction X compared to the leg opening 52, the outer edge of the rear crotch region R13 in the lateral direction Y is the lateral boundary BY.

[0053] Alternatively, the rear crotch region R13 may have a rear leg region R31 adjacent to the leg opening 52, and a rear lower crotch region R32 located between the rear middle region R12 and the rear leg region R31. The rear leg region R31 may be a region extending from the leg opening 52 within a certain range, for example, it may be a range extending from the leg opening 52 to 20 mm. Alternatively, in a configuration where the component surrounding the leg opening 52 is composed of components different from those in other regions, the rear leg region R31 may be configured with components surrounding the leg opening 52. Figure 7 The area of ​​the back lace fabric 322 in this embodiment is shown.

[0054] like Figure 7 As shown, the rear crotch region R13 of this embodiment is composed of multiple components. The components of the rear crotch region R13 include: a third crotch member 133, which continues from one lateral boundary BY to another lateral boundary BY; a crotch member 140, which is adjacent to the third crotch member 133 in the longitudinal direction X; and a rear lace fabric 322. The rear lace fabric 322 is disposed adjacent to the third crotch member 133. The rear lace fabric 322 is disposed along the leg opening 52. The rear lace fabric 322 can constitute a high-stretch portion, as described later. The rear lace fabric 322 may be a fabric whose tensile force in the leg circumference direction is higher than that of the third crotch member 133, and whose tensile force in the leg circumference direction is higher than that of the crotch member 140. The rear leg region R31 may be the region where the rear lace fabric 322 is disposed, and the rear lower crotch region R32 may be the region where the third crotch member 133 is disposed.

[0055] The front waist region F11, front crotch side region F13, and front middle region F12 are not defined by different components, but rather by the shape of the front panel and its contact point with the body. Therefore, each of these regions can be composed of different components or may include components spanning multiple regions. Furthermore, each region can be composed of a single component or multiple components. Similarly, the rear waist region R11, rear crotch side region R13, and rear middle region R12 are not defined by different components, but rather by the shape of the rear panel 20 and its contact point with the body. Therefore, each of these regions can be composed of different components or may include components spanning multiple regions. Furthermore, each region can be composed of a single component or multiple components.

[0056] The shorts 1 of this embodiment are configured to easily and continuously cover the body even when waist size and waist circumference change due to changes in body posture. When the wearer's posture changes, waist size and waist circumference change; generally, waist size and waist circumference change when sitting compared to a standing position. The applicant conducted in-depth research on the wearing conditions of shorts and found that the abdominal circumference of middle-aged women is larger than that of younger women. Furthermore, it is known that, depending on posture, for example, the abdominal circumference changes by about 3cm to 5cm between standing and sitting positions. Additionally, for middle-aged women, the boundaries of the hips and upper thighs tend to become less distinct compared to younger women. Therefore, it is difficult to continuously cover the abdomen and hips with shorts. The shorts 1 of this embodiment are configured to easily and continuously cover the body even when waist size and waist circumference change due to changes in body posture. The structure for easily and continuously covering the body even when waist size and waist circumference change due to changes in body posture is generally divided into a first structure and a second structure. The shorts 1A of the first embodiment has at least a first structure, and the shorts 1B of the second embodiment has at least a second structure. Furthermore, the shorts 1A of the first embodiment may have a second structure, or the shorts 1B of the second embodiment may have a first structure.

[0057] In the first structure, the 1.3 times stretching force in the front middle region F12 is higher than the 1.3 times stretching force in the front waist region F11. In this embodiment, the shorts 1A of the first embodiment have the first structure. When wearing the shorts 1 with the front panel 10 covering the abdomen, the front waist region F11 covers the area around the navel, and the front crotch region F13 covers the groin area. The front middle region F12 is closer to the crotch side than the area around the navel and higher than the groin area, making it easy to cover the iliac crest. The applicant has conducted in-depth research on the way the shorts are worn, and as a result, the shorts are stretched from their natural state when worn, and the shorts fit the body with a stretch of about 1.3 times when worn. The wearer does not feel pressure at the iliac crest, so the 1.3 times stretching force of the front middle region F12 covering the iliac crest can be greater, thereby suppressing discomfort and keeping the shorts in place relative to the iliac crest. For the front waist region F11, which is located above the front middle region F12, its 1.3 times stretching force is smaller than that of the front middle region F12. Even if the waist size changes, it can follow the body while suppressing the feeling of pressure. It can easily and continuously cover the bulge of the abdomen and suppress the unevenness of the abdomen at the edge of the waist.

[0058] "1.3 times tensile force" refers to the tensile force at a stretch of 1.3 times (stretch rate 30%) when the stretch rate is 1.0 times (0% as the natural state) and 2.0 times (100% as the stretching state in the transverse direction). The tensile force can be measured using an Instron instrument. A sample (approximately 50mm wide x 130mm long) is cut from the area to be measured. Furthermore, if the sample width is less than 50mm, the value is converted to a 50mm width. The tensile force is measured at 1.3 times the stretch rate (130mm between chucks) after stretching to 100% (200mm between chucks) at a stretching speed of 300mm / min with a 100mm gap between chucks, followed by recovery (100mm between chucks). This tensile force at 1.3 times the stretch rate (130mm between chucks) is defined as the "1.3 times tensile force" of this invention. Figure 4 This indicates the measurement result of tensile force. Figure 4 The result is a measurement of the tensile force in the shorts 1A of the first embodiment.

[0059] In the second structure, in the natural state of the shorts 1, the maximum length of the transverse direction Y of the front middle region F12 is shorter than the maximum length of the transverse direction Y of the front waist region F11, and also shorter than the maximum length of the transverse direction Y of the front crotch side region F13. In this embodiment, the shorts 1B of the second embodiment has the second structure. When worn with the front panel 10 of the shorts 1 covering the bulge of the abdomen, the front waist region F11 covers the area around the navel, and the front crotch side region F13 covers the groin area. The front middle region F12 is closer to the crotch side than the area around the navel and higher than the groin area, making it easy to cover the iliac crest. The wearer is less likely to feel pressure at the iliac crest, therefore the maximum size of the front middle region covering the iliac crest is shorter, which can suppress discomfort and keep the shorts in place relative to the iliac crest. For the front waist area F11 located above the front center area F12, its natural length is longer than that of the front center area F12, ensuring continuous coverage of the abdomen without compressing it, even if the wearer's waist size changes. For the front crotch side area F13 located on the crotch side of the front center area F12, its natural length is longer than that of the front center area F12, ensuring continuous coverage of the body even if waist size changes.

[0060] It is possible that, in the shorts 1B of the second embodiment having the second structure, the 1.3 times tensile force in the front middle region F12 is lower than the 1.3 times tensile force in the front waist region F11. Figure 9These are the measurement results of the tensile force in the shorts 1B of the second embodiment. In the natural state, the front middle area, which has the shortest maximum length in the lateral direction Y, stretches the most and fits the body most closely. During the stretching process to 1.3 times the length when worn, the tensile stress in the front middle area is low. Therefore, even if the waist size changes, it can stretch without excessively constricting the body when worn. In addition, for the front waist area F11, since its lateral length is relatively long in the natural state, it fits the body gently without stretching relative to the wearer's waist size. Even when the waist size increases during the stretching process to 1.3 times the length when worn, it can continuously cover the bulge of the abdomen without compressing the abdomen.

[0061] In a variation of the shorts 1B of the second embodiment, the 1.3 times stretching force in the front middle region F12 is equal to the 1.3 times stretching force in the front waist region F11. Under the 1.3 times stretching condition, the stretching force in the front middle region F12 is equal to the stretching force in the front waist region F11, thereby enabling continuous coverage of the abdominal bulge without compressing the abdomen.

[0062] Next, a preferred embodiment of both the shorts 1A of the first embodiment and the shorts 1B of the second embodiment will be described. In the natural state of the shorts 1, the maximum length in the lateral direction Y of the back center region R12 is shorter than the maximum length in the lateral direction Y of the back waist region R11, and also shorter than the maximum length in the lateral direction Y of the back crotch region R13. Since the front center region F12 and the back center region R12, which have relatively short lateral direction Y lengths, are connected, the shorts can be held in place by using the front center region F12 and the back center region R12 to surround the waist. It is easy to use the front center region F12 and the back center region R12 to fit snugly against the waist, and easy to use the upper waist region and the crotch region to continuously cover the body.

[0063] Alternatively, the front middle section F12 can bend downwards towards the crotch from the side of the front panel 10 in the lateral direction Y towards the center of the front panel 10 in the lateral direction Y. According to this method, the front middle section F12 can be easily positioned at the pelvic position connecting the pubic symphysis and the anterior superior iliac spine. Since the pelvic position connecting the pubic symphysis and the anterior superior iliac spine is a position where the wearer is less likely to feel pressure, it is easier to suppress discomfort and maintain the overall position of the shorts 1, making it easier to continuously cover the body even with changes in body posture.

[0064] In a modified example, the front intermediate region F12 extends straight along the transverse direction Y. Furthermore, the length of the front intermediate region F12 in the longitudinal direction X can be either constant or variable. Alternatively, it can be as follows: Figure 2 and Figure 6 As shown, the rear middle region R12 extends without bending along the lateral direction Y.

[0065] It is possible that the longitudinal bending stiffness (X) of the rear waist region R11 is higher than that of the front waist region F11. The front waist region F11 has a lower longitudinal bending stiffness (X), making it prone to wrinkling when the longitudinal dimension (X) of the abdomen changes due to posture variations. The rear waist region R11 has a higher longitudinal bending stiffness (X), allowing it to support the ends of the front waist region F11 at the sides where the longitudinal dimension (X) changes less. This reduces wrinkling in the front waist region F11 and makes it easier to flatten wrinkles when they occur. Furthermore, for structures that increase the stiffness of the rear waist region R11, a high-stiffness fabric can be used to construct the rear waist region R11, or a high-stiffness section (e.g., a seam) extending longitudinally can be provided in the rear waist region R11.

[0066] Here, longitudinal stiffness can be measured according to the bending resilience method in JIS L1096 8.22. A sample (25mm wide × 38mm long) can be cut from the area of ​​the object to be measured and measured using a Gurley-type softness tester (Yasuda Seiki Co., Ltd. No. 311). The measurement conditions are based on Gurley's standards.

[0067] The front center area F12 and the back center area R12 may be constructed from a continuous tubular fabric in the transverse direction Y. The continuous tubular fabric may not have stitches for sewing adjacent areas in the transverse direction Y; for example, it may be made of a woven fabric. Alternatively, a continuous tubular elastic thread in the transverse direction Y may be provided on the tubular fabric. Since the front center area F12 and the back center area R12 are constructed from continuous tubular fabric, tension is easily linked between the front body piece 10 and the back body piece 20, thus maintaining a close fit relative to the body. Furthermore, since the elastic thread is also tubular, it is less likely to detach, thereby easily maintaining tension in the center areas. Moreover, in the manner in which the longitudinal positions of the front center area F12 and the back center area R12 are offset, as long as at least one elastic thread is arranged in a tubular shape, it is acceptable.

[0068] In the modified shorts example, in the natural state of the shorts, the waist opening 51 of the front panel 10 extends outward in the longitudinal direction X compared to the waist opening 51 of the back panel 20. According to this method, the front panel 10 can easily ensure coverage of the bulge of the abdomen, and it is easy to maintain continuous coverage of the abdomen. Furthermore, regarding the structure where the waist opening 51 of the front panel 10 extends outward in the longitudinal direction X, it can be a structure where the component constituting the front middle region F12 bends outward in the longitudinal direction X, thereby causing the waist opening 51 of the front panel 10 to extend outward in the longitudinal direction X. Alternatively, it can be a structure where the front middle region F12 is extended in the transverse direction Y or bent inward in the longitudinal direction X, and the longitudinal direction X length of the center of the transverse direction Y of the front waist region F11 is longer, thereby causing the waist opening 51 of the front panel 10 to extend outward in the longitudinal direction X.

[0069] Alternatively, it could be in other ways, such as Figure 5 and Figure 6 As shown, in the natural state of the shorts, the waist opening 51 of the front panel 10 does not extend to the outer side in the longitudinal direction X of the waist opening 51 of the back panel 20, but rather its position in the longitudinal direction X is approximately the same as that of the waist opening 51 of the back panel 20. Furthermore, this approximately consistent structure means that the longitudinal offset between the waist opening 51 of the back panel and the waist opening 51 of the front panel 10 is less than 5 mm. Alternatively, in the manner where the waist openings of the back panel and the front panel 10 are consistent, the front middle region F12 curves downwards from the side of the front panel in the lateral direction toward the center of the front panel towards the crotch, and the longitudinal length of the center of the front waist region F11 in the width direction is longer than the longitudinal length of the side of the front waist region in the width direction. According to this method, it is also easy to utilize the front panel to ensure coverage of the bulge of the abdomen, and it is easy to continuously cover the abdomen.

[0070] Alternatively, the longitudinal X length of the front middle region F12 at the lateral boundary BY can be shorter than the longitudinal X length of the front crotch side region F13 at the lateral boundary BY, and also shorter than the longitudinal X length of the front waist region F11 at the lateral boundary BY. According to this method, by preventing the longitudinal X length of the front middle region F12, which is maintained relative to the body, from becoming excessively long, the shorts are kept in place while suppressing any feeling of pressure on the body. Furthermore, by ensuring the longitudinal X lengths of the front waist region F11 and the front crotch side region F13, it is easy to maintain continuous coverage of the abdomen and buttocks.

[0071] The longitudinal length of the front middle region F12 at the lateral boundary BY can be less than 0.5 times the longitudinal length X of the front crotch side region F13 at the lateral boundary BY, and preferably less than 0.3 times the longitudinal length X of the front crotch side region F13 at the lateral boundary BY. Alternatively, the longitudinal length of the front middle region at the lateral boundary can be less than 0.7 times the longitudinal length of the front waist region at the lateral boundary BY. The longitudinal length of the front middle region at the lateral boundary can be less than 0.3 times the longitudinal length of the front body piece at the lateral boundary, and preferably less than 0.2 times the longitudinal length of the front body piece at the lateral boundary.

[0072] Alternatively, a high-tension section can be provided in the front leg region F31, in which the circumferential stretching force surrounding the wearer's leg is higher than that in the front crotch region F32. The high-tension section can be at least partially formed by the front leg region F31. In this embodiment, the high-tension section is made of front lace fabric 321 and is located at the inner end of the second crotch side member 132 in the longitudinal direction, but not in the first crotch side member 131 or the crotch member 140. The high-tension section extends inward from the lateral boundary BY in the lateral direction Y and is located on the outer side of the lateral direction Y, which is closer to the inner edge of the leg opening 52 (the outer edge of the crotch member 140 in the lateral direction Y). Alternatively, a high-tension section can be provided in the rear leg region R31, in which the circumferential stretching force is higher than that in the rear crotch region R32. The rear high stretch portion may be at least partially formed by the rear leg region R31. In this embodiment, the rear high stretch portion is formed by rear lace fabric 322 and is located at the inner end of the third crotch side member 133 in the longitudinal direction. Alternatively, one end of the front high stretch portion in the leg circumference direction may be connected to the rear high stretch portion, and the other end of the front high stretch portion in the leg circumference direction may be connected to the front middle region F12.

[0073] According to this method, due to the presence of a high-stretch rear section, the hip area can be stably covered relative to the leg opening 52 of the back panel, ensuring complete coverage of the hips. Even in body types where the boundaries between the hips and the upper thighs are not clearly defined, it is easy to prevent the shorts from shifting and to provide continuous coverage of the body. Furthermore, one end of the high-stretch front section in the leg circumference direction is connected to the high-stretch rear section, and the other end of the high-stretch front section in the leg circumference direction is connected to the front center area F12. This prevents the leg area from shifting or slipping, making it easy to lift the shorts and provide continuous coverage of the body even in body types where the boundaries between the hips and the upper thighs are not clearly defined. Alternatively, the width of the high-stretch rear section (its length in a direction orthogonal to the leg circumference direction) can be longer than the width of the high-stretch front section.

[0074] Alternatively, the first crotch-side member 131 and the second crotch-side member 132 may be disposed in the front leg region F31. Alternatively, the first crotch-side member 131 and the second crotch-side member 132 in the front leg region F31 may be stacked in a non-engaged state. Since the first crotch-side member 131 and the second crotch-side member 132 in the front leg region F31 are stacked together non-engaged, their relative positions change according to leg movement, easily following the body. Therefore, it is easy to suppress the situation where the leg opening 52 is pulled towards the abdomen due to leg movement, and it is easy to continuously cover the lower end of the buttocks and the bulge of the buttocks. In this embodiment, the first crotch-side member 131 and the second crotch-side member 132 are engaged with each other at the lateral boundary BY, but not engaged in other areas. Therefore, the relative positions of the inner edge of the first crotch side member 131 and the inner edge of the second crotch side member 132 are easily changed due to leg movement, etc., and can easily and continuously cover the leg circumference without hindering leg movement.

[0075] The shorts 1 in this embodiment are not menstrual shorts or shorts for mild incontinence, but rather shorts used as underwear. However, in variations, the shorts may be reusable absorbent shorts such as menstrual shorts or shorts for mild incontinence. The crotch member 140 may have: an absorbent layer that absorbs bodily fluids; a low-water-retention layer that covers the skin-side surface of the absorbent layer and has lower water-retention than the absorbent layer; and a low-permeability layer that covers the non-skin-side surface of the absorbent layer and has lower permeability than the absorbent layer.

[0076] The absorbent layer absorbs (retains) bodily fluids guided from the surface of the crotch member (in this embodiment, a low-water-retention layer). The absorbent layer has fibers configured to temporarily absorb bodily fluids by retaining them between the fibers. The configuration is such that by washing the shorts 1, the bodily fluids between the fibers can be removed, and then by drying the shorts, the moisture between the fibers evaporates, and the absorbent layer returns to its state before absorbing the bodily fluids. The absorbent layer of this embodiment has microfibers as fibers.

[0077] The low-water-retention layer may contain fibers with lower water retention than the absorbent layer. In this embodiment, the low-water-retention layer contains wool fibers. Alternatively, the low-water-retention layer may be primarily composed of non-absorbent fibers. Here, non-absorbent fibers are fibers that do not readily absorb moisture, including fibers that absorb only small amounts of moisture. Specifically, non-absorbent fibers are fibers with a standard moisture regain of 5% or less. Standard moisture regain is a value representing the moisture regain within the fiber under conditions of 20°C and 65% humidity. The low-water-retention layer may or may not absorb water.

[0078] The low-permeability layer can be a water-repellent layer or a waterproof (liquid-impermeable) layer. In this embodiment, the low-permeability layer is coated with fluorine, silicone, or the like. The low-permeability layer can be configured to directly cover the non-skin side of the absorbent layer, or it can be indirectly covered by other components in between.

[0079] According to this method, an absorbent layer can be used to retain bodily fluids such as urine, and a low-permeability layer located on the skin side of the absorbent layer can be used to inhibit fluid residue, thereby improving skin feel. Furthermore, since a low-permeability layer can be used to cover the non-skin side of the absorbent layer, the seepage of bodily fluids can be suppressed.

[0080] Alternatively, the area of ​​the joint formed by bonding the absorbent layer and the low-permeability layer may be less than 20% of the area of ​​the overlapping region of the absorbent layer and the low-permeability layer. Alternatively, the absorbent layer and the low-permeability layer may be laminated in a non-bonded state. According to this method, bodily fluids guided to the low-permeability layer are transferred to the absorbent layer located on the non-skin side and retained by the absorbent layer. Because of the joint, the absorbent layer and the low-permeability layer adhere tightly, and the increased density in the joint allows for smooth transfer of bodily fluids to the absorbent layer side. Furthermore, since the area ratio of the joint is less than 20%, the absorbent layer and the low-permeability layer are easily separated, improving breathability during wear and facilitating drying when drying in reusable shorts. Alternatively, the joint between the absorbent layer and the low-permeability layer may not be located in the center of the crotch member in the longitudinal direction, but rather on the outer side of the crotch member in the longitudinal direction.

[0081] The present invention has been described in detail above using the embodiments described above. However, it will be apparent to those skilled in the art that the present invention is not limited to the embodiments described in this specification. The present invention can be implemented in modified and altered ways without departing from the spirit and scope of the invention as defined by the claims. Therefore, the description in this specification is for illustrative purposes only and does not have any limiting meaning for the present invention.
