Description

[Technical Field]

[0001] The present invention relates to water-absorbing sanitary shorts. [Background technology]

[0002] Recently, there has been growing interest in Femtech (female + technology), which refers to services and products that use technology to solve women's health problems. In addition, with the global trend toward promoting the SDGs, there is a growing trend toward developing products that are reusable as much as possible, rather than disposable.

[0003] Against this background, various types of absorbent sanitary shorts have been actively developed in recent years as women's underwear with added functions to make menstruation more comfortable. Absorbent sanitary shorts have features such as a double-reinforced crotch that connects the front and back, and can be worn in the same way as regular shorts when you feel anxious before and after your period.

[0004] Sanitary shorts aim to reduce the mental and financial burden of having to worry about soiling clothing and having to carry and use extra pads, and in recent years, many inventions and creations have been made public, with one of the main challenges being to improve the so-called leakage prevention function from the crotch, as shown below.

[0005] Patent Document 1 discloses "underwear for incontinence having an underwear main body with a gusset portion and a water-absorbent member provided on the inner surface of the gusset portion, the water-absorbent member comprising a water-absorbent sheet arranged with its back surface facing the inner surface of the gusset portion, a waterproof sheet fixed to the water-absorbent sheet so as to cover the entire back surface and side edges of the front surface of the water-absorbent sheet, and a fixing sheet having one edge fixed along the side edges of the water-absorbent sheet and the other edge fixed to the underwear main body, the fixing sheet having water-repellent properties, and one edge of the fixing sheet being sandwiched between the side edges of the front surface of the water-absorbent sheet and the waterproof sheet." According to the invention in Patent Document 1, one edge of the fixing sheet is sandwiched between the side edges of the front surface of the water-absorbent sheet and the waterproof sheet and sewn together, so that no seams are formed on the back surface of the water-absorbent sheet, preventing liquid leakage between the water-absorbent sheet and the waterproof sheet. Furthermore, since the water-absorbing sheet is covered liquid-tightly by the waterproof sheet, the moisture absorbed by the water-absorbing sheet does not leak to the outside, and a high degree of side leakage prevention can be achieved.

[0006] Patent Document 2 discloses a design for sanitary shorts that have an absorbent area on the skin side of the crotch area when worn, with waterproof areas arranged on the sides of the absorbent area. These sanitary shorts are underwear that have an underwear main body with a gusset and an absorbent area provided on the inner surface of the gusset, and can be described as sanitary shorts with waterproof areas arranged on the sides of the absorbent area.

[0007] [Patent Document 1] Patent No. 3718213 [Patent Document 2] Design Registration No. 1672610 Summary of the Invention [Problem to be solved by the invention]

[0008] However, while the underwear disclosed in Patent Document 1 has an excellent effect in preventing side leakage from the water-absorbent member provided on the inside of the gusset, it does not waterproof the front and rear of the water-absorbent member, and does not consider the edges of the leg openings. Therefore, it cannot be said to be an invention that takes into consideration the sanitary and comfortable properties of the crotch area, which reinforces the gusset, or the underwear as a whole.

[0009] Furthermore, the sanitary shorts described in Patent Document 2 appear to have insufficient water absorption due to their narrow gusset. Furthermore, the rubber around the leg openings of the crotch is not covered with a waterproof sheet, resulting in a weak waterproofing effect that prevents menstrual blood, urine, and other bodily fluids from leaking sideways from the crotch. Furthermore, the straight edges of the left and right leg openings of the gusset do not fit the wearer's left and right leg openings. Even if the rubber around the leg openings were waterproofed, the waterproofing effect is not semi-permanent and does not guarantee long-term waterproofing. Therefore, the invention cannot be said to take into consideration the sanitary and comfortable nature of the crotch or the underwear as a whole.

[0010] This invention was developed in light of these circumstances, and provides absorbent sanitary shorts that not only improve the water absorption and waterproofing of bodily fluids such as menstrual blood and urine during menstruation, but also add functions to make menstruation more comfortable, pursuing sanitary and comfortable conditions for the crotch and the entire underwear from a femtech perspective. [Means for solving the problem]

[0011] The water-absorbing sanitary shorts according to the present invention are sanitary shorts having an inner surface that fits closely to the wearer's skin and an edge portion of the left and right leg openings that fits closely to the wearer's left and right leg openings, respectively, and comprising a front body and a back body, and a crotch portion that connects the front body and the back body and has a sanitary structure on the inner side of the base, The sanitary structure is a water-absorbent sanitary shorts structure in which a water-absorbent area is formed by binding a water-absorbent member with a waterproof fixing sheet in the center of the inner side of the base that constitutes the crotch, and waterproof areas are formed on the sides of the water-absorbent area, The absorbent member arranged in the absorbent area is constructed by stacking multiple sheets including an absorbent sheet, is surrounded by a front edge, a rear edge, and left and right edges, and is roughly similar in shape to the crotch, and the front and rear edges each extend forward and backward along the leg opening edges of the crotch at least to the boundary between the front and back body sections, and the front, rear, and left and right waterproof fixing sheets are sewn to the absorbent member and the crotch base so as to cover the front edge, rear edge, and left and right edges of the absorbent member, respectively, joining the absorbent member to the crotch base and forming waterproof areas on the front, rear, left, and right sides.

[0012] In the water-absorbing sanitary shorts according to the present invention, the front body, the back body, and the crotch base have exposed body fabric on their outer surfaces, The crotch base is preferably formed by laminating a waterproof fabric on the inside of the outer body fabric, or the inner surface of the body fabric is preferably waterproof.

[0013] The water-absorbent sanitary shorts according to the present invention comprise a water-absorbent member having front and rear waterproof fixing sheets joined together to form the front and rear waterproof regions, The left and right waterproof fixing sheets were placed over the front and rear edges covered by the waterproof fixing sheet to cover the left and right edges of the water-absorbing member, thereby forming the left and right waterproof areas.

[0014] The water-absorbent sanitary shorts according to the present invention are water-absorbent sanitary shorts, in which a common stretchable material is sewn to the leg opening edges of the crotch, the front body, and the back body, which constitute the leg opening edges that fit closely to the left and right leg openings of the wearer, In the crotch, the stretchable material is placed toward the center from the outer edge along the leg opening edge where the base fabric constituting the crotch and the left and right waterproof fixing sheets are superimposed, and the outer edge along the leg opening edge is folded back toward the inner center to encase it, and the base fabric and the left and right waterproof fixing sheets are sewn together with the encased stretchable material to form a waterproof region at the leg opening edge.

[0015] In the water-absorbent sanitary shorts according to the present invention, the front edge and / or the rear edge of the water-absorbent member is formed in an arc shape.

[0016] In the water-absorbent sanitary shorts according to the present invention, the plurality of sheets of the water-absorbent member joined to the water-absorbent region include at least a waterproof sheet and a water-absorbent sheet, in that order, toward the inside of the crotch. [Effects of the Invention]

[0017] The water-absorbent sanitary shorts of the present invention have a sanitary structure formed in the crotch connecting the front and back bodies, and a water-absorbent member attached to the center of the inside of the base that makes up the crotch with a waterproof fixing sheet to form a water-absorbent area. The water-absorbent area extends front and back along the leg opening edges of the crotch up to the boundaries between the front and back bodies and the crotch, and extends over almost the entire surface of the crotch, having a shape roughly similar to that of the crotch, so it can exhibit sufficient water absorption.

[0018] Furthermore, the water-absorbent member is placed on a base in which a waterproof cloth is laminated on the inside of the crotch body fabric, or the inner surface of the body fabric is made of a waterproof fabric, and the front, back, left, and right edges are covered with waterproof fixing sheets to form a water-absorbent region, so that the front, back, left, and right sides of the water-absorbent region become waterproof regions.The waterproof fixing sheets covering the front, back, left, and right edges of the water-absorbent member are sewn to the edges of the crotch base fabric at the crotch leg opening edges, so that the waterproof region can prevent moisture from leaking from the front, back, left, and right edges of the water-absorbent region.

[0019] Furthermore, the water-absorbent sanitary shorts of the present invention have a common elastic material sewn to the leg opening edges of the crotch and the front and back panels, which make up the leg opening edges.The leg opening edges of the crotch form a waterproof area, but the leg opening edges of the front and back panels are made with a flat-felled stitch that has elastic material such as rubber on the skin side, which prevents slippage and improves the fit around the leg openings of the wearer, while minimizing thickness and making them comfortable to wear.

[0020] As described above, the waterproof areas at the leg openings of the crotch are formed by folding the edges of the crotch base and the seams of the waterproof fixing sheet inward toward the inside of the crotch, enveloping the stretchable material arranged around the leg openings of the crotch, and then sewing the stretchable material to the base together with the stretchable material. In this way, the waterproof areas at the leg openings provided at the ends of the waterproof areas on the left and right of the absorbent area can doubly prevent bodily fluids such as menstrual blood and urine from leaking out of the crotch from the edges of the absorbent area.

[0021] In the water-absorbent sanitary shorts of the present invention, the water-absorbent region extends along the leg edges to the boundary between the front and back body sections and spreads in a similar shape over almost the entire surface of the crotch, giving the wearer a comfortable fit and a sense of security in the crotch area and also addressing the chill caused by menstruation.Furthermore, the front and rear edges of the water-absorbent member that makes up the water-absorbent region are arc-shaped, which allows the distance to the crotch centerline to be longer, allowing more sufficient absorption of body fluids such as menstrual blood and urine from the urethra and vaginal opening that tend to flow along the intergluteal cleft, enhancing the wearer's sense of security.

[0022] As described above, the absorbent sanitary shorts of the present invention are capable of exhibiting sufficient water absorption and waterproofing, thereby reducing the worries of the wearer about soiling their clothing and the mental and financial burden of having to carry and use extra pads. Furthermore, by providing a sufficiently large absorbent area in the crotch and stretchable leg opening edges that provide waterproofing and improve the fit around the leg openings, the sanitary properties and comfort of the crotch and the entire underwear are improved, allowing the wearer to spend their menstrual period with greater peace of mind and comfort.

[Figure 3] 1A is a plan view of a water-absorbent member according to the present invention, and FIG. 1B is a cross-sectional view taken along line BB. [Figure 4] FIG. 2 is a cross-sectional view of the crotch according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0024] Hereinafter, embodiments and examples of water-absorbent sanitary shorts according to the present invention will be described with reference to the drawings. Note that the same reference numerals will be used to designate the same components throughout the drawings.

[0025] As shown in Figure 1, the water-absorbent sanitary shorts 1 of the present invention fit closely to the wearer's skin at the inside, and fit closely to the left and right leg openings at the left and right leg opening edges 4. The shorts are composed of a front body 2, a back body 3, and a crotch 10 that connects the front and back body 2 and 3 at boundaries FC and BC. The front body 2, the back body 3, and the crotch 10 have exposed body fabric on their outer surfaces. The crotch 10 also has a sanitary structure 11 on the inside of the base 10U.

[0026] (Sanitary structure) As shown in Figures 2(a), (b) and 3(a), (b), the sanitary structure 11 has a structure in which a water-absorbent member 20 is bonded with a waterproof fixing sheet 30 to form a water-absorbent region 12 in the center of the inside of the underlayment 10U that constitutes the crotch 10, and waterproof regions 13 (13L, 13R, 13F, 13B) are formed on the sides of the water-absorbent region 12. Bonding can be performed using conventional bonding methods such as sewing with a sewing machine, bonding with an adhesive, or thermocompression bonding. When sewing with a sewing machine, it is preferable to use a water-repellent thread.

[0027] (Water-absorbent area and waterproof area) 2(a) and 3(a), the water-absorbent member 20 is configured such that the front, rear, and left and right waterproof fixing sheets 30F, 30B, 30L, and 30R cover the front edge 22F, rear edge 22B, and left and right edges 22L and 22R of the water-absorbent member 20, respectively, and are sewn and joined to the underlayment 10U of the crotch 10. Therefore, the central portion where the front, rear, and left and right edges 22F, 22B, 22L, and 22R are covered by the front, rear, and left and right waterproof fixing sheets 30F, 30B, 30L, and 30R constitutes the water-absorbent region 12. Furthermore, the front, rear, and left and right waterproof fixing sheets 30F, 30B, 30L, and 30R covering the front, rear, and left and right edges 22F, 22B, 22L, and 22R directly constitute the front, rear, and left and right waterproof regions 13F, 13B, 13L, and 13R.

[0028] (Structure of water-absorbing region) As shown in the cross-sectional views of Figures 2(b) and 3(b), the water-absorbent member 20 forming the water-absorbent region 12 is constructed by stacking multiple sheets including a water-absorbent sheet 24. These multiple sheets include at least a waterproof sheet 26 and a water-absorbent sheet 24, in that order, toward the inside of the crotch 10. For example, as shown in Figures 2(b) and 3(b), the multiple sheets forming the water-absorbent member 20 are stacked in the following order from the base 10U of the crotch 10 toward the inside: the waterproof sheet 26, the bacteriostatic sheet 25, the water-absorbent sheet 24, and the skin-facing sheet 23.

[0029] The materials of the sheets other than the waterproof sheet 26 and the water-absorbent sheet 24 can be changed as appropriate depending on the purpose, and the number of sheets to be stacked is not particularly limited. The waterproof sheet 26 in the water-absorbent member 20 is preferably, but not limited to, one having moisture-permeable and waterproof properties to reduce stuffiness. The water-absorbent sheet 24 is preferably, but not limited to, one that is absorbent and quick-drying, such as a terry cloth sheet. The antibacterial sheet 25 is preferably, but not limited to, one that has a moisture-permeable and waterproof properties to prevent odors and one that has moisture-permeable and waterproof properties to reduce stuffiness, such as, but not limited to, a moisture-permeable and waterproof terry cloth sheet. The skin-facing sheet 23 is preferably, but not limited to, one that is quick-drying and antibacterial, such as, but not limited to, a mesh sheet.

[0030] The underlayment 10U of the crotch 10 may be a single layer of fabric or a single piece of waterproof fabric, with the inner surface of the main fabric 10Ua waterproofed, as shown in FIG. 2(b), or may be a two-layer structure with a waterproof fabric 10Ub laminated on the inside of the main fabric 10Ua, as shown in FIG. 3(b). The number of layers and material are not particularly limited as long as the inner surface is waterproof. Examples of materials that can be used for the main fabric include synthetic fibers, recycled fibers, natural fibers such as cotton, linen, and silk, and fibers made from composites of these fibers. Furthermore, the use of heat-retaining or heat-generating materials can reduce swelling caused by cold. The waterproof fabric 10Ub is preferably, but not limited to, a breathable, waterproof material to reduce stuffiness.

[0031] (Water-absorbing material) The water-absorbent member 20 constituting the water-absorbent region 12 is surrounded by a front edge 22F, a rear edge 22B, and left and right edges 22L, 22R, as shown in Figures 2(a) and 3(a). Its shape is substantially similar to that of the crotch 10, and the front edge 22F and the rear edge 22B extend forward and backward along the leg opening edges 14 of the crotch, at least up to the boundaries FC and BC between the front body 2 and the back body 3, respectively. It is preferable that the front edge 22F and / or the rear edge 22B of the water-absorbent member 20 be arc-shaped, as shown in Figures 2(a) and 3(a).

[0032] As described above, the front, rear, left, and right edges 22F, 22B, 22L, and 22R of the water-absorbent member 20 are covered with the front, rear, and left and right waterproof fixing sheets 30F, 30B, 30L, and 30R, and the water-absorbent region 12 is formed in the center. The water-absorbent region 12 has a shape similar to the crotch 10, as shown in Figures 2(a) and 3(a), and the water-absorbent surface is larger at the rear than at the front of the wearer. Since the water-absorbent member 20 has a multi-layer structure to prevent liquid leakage, the water-absorbent region 12 is prone to becoming stuffy. Therefore, by widening the waterproof regions on the sides toward the rear, the feeling of stuffiness is reduced and the garment appears lightweight in terms of appearance (design).

[0033] Furthermore, by making the front edge 22F and / or the rear edge 22B of the absorbent member 20 arc-shaped, the distance of the crotch center line can be made longer, which allows more sufficient absorption of bodily fluids such as menstrual blood and urine from the urethra and vaginal opening that tend to flow along the intergluteal cleft, thereby increasing the wearer's sense of security.

[0034] (waterproof area) As described above, when the front, rear and left and right waterproof fixing sheets 30F, 30B, 30L and 30R cover the front, rear and left and right edge portions 22F, 22B, 22L and 22R of the water-absorbing member 20 and are joined to the base 10U of the crotch 10, the front, rear and left and right waterproof regions 13F, 13B, 13L and 13R are formed (see Figures 2(a) and 3(a)).

[0035] 2(b) and 3(b), the left and right waterproof fixing sheets 30L, 30R and the front and rear waterproof fixing sheets 30F, 30B are joined to the base 10U at their edges to form front, rear, left and right waterproof regions 13F, 13B, 13L, 13R. The base 10U is made up of two layers, with the inner surface of the body fabric 10Ua waterproofed as shown in FIG. 2(b), or with a waterproof fabric 10Ub laminated on the inside of the body fabric 10Ua as shown in FIG. 3(b), so that side leakage from the water-absorbent member 20 can be contained within the waterproof region 13.

[0036] 2(b) and 3(b), one edge of the front, back, left, and right waterproof fixing sheets 30F, 30B, 30L, 30R is sewn to the front, back, left, and right edges 22F, 22B, 22L, 22R of the water-absorbent member 20, and the other edge is joined to the base 10U, so that a slight gap is created between this one edge and the other edge, which reduces the thickness around the leg edge 14 and reduces the stuffiness of the water-absorbent member 20 caused by the multi-layer structure. Furthermore, the rear waterproof fixing sheet 30B may extend beyond the boundary between the back body and the crotch to improve waterproofness, or may extend up to the waist part of the back body. [Example]

[0037] In the water-absorbent sanitary shorts 1 according to this embodiment shown in Figures 2(a) and 3(a), first, the front and rear waterproof fixing sheets 30F, 30B cover the front and rear edge portions 22F, 22B of the water-absorbent member 20, forming front and rear waterproof regions 13F, 13B. Next, the left and right waterproof fixing sheets 30L, 30R are placed over the front edge portion 22F and the rear edge portion 22B covered by the front and rear waterproof fixing sheets 30F, 30B, covering the left and right edge portions 22L, 22R of the water-absorbent member 20 and forming the left and right waterproof regions 13L, 13R.

[0038] The water-absorbent sanitary shorts 1 of this embodiment can contain body fluid leakage from the water-absorbent member 20 along the front and rear edges 22F, 22B to the left and right by the left and right waterproof fixing sheets 30L, 30R. Therefore, the water-absorbent sanitary shorts 1 of this embodiment can improve the effectiveness of preventing side leakage of body fluids such as menstrual blood and urine from the crotch 10. [Example]

[0039] (Waterproof area at the edge of the legs) In the absorbent sanitary shorts 1 of this embodiment, it is desirable that a common elastic material 5 be sewn to the crotch 10 and the leg opening edges of the front body 2 and back body 3, which form the leg opening edges 4 that fit closely to the left and right leg openings of the wearer.

[0040] In the crotch 10 of this embodiment, the stretchable material 5 is first placed toward the center from the outer edge along the leg opening edge 14 of the crotch, which is made up of the underlayment 10U and the left and right waterproof fastening sheets 30L, 30R that make up the crotch 10. Then, as shown in Figure 4, the outer edges of the underlayment 10U and the left and right waterproof fastening sheets 30L, 30R that are along the leg opening edge 14 are folded back toward the inner center to encase the stretchable material 5, and the underlayment 10U and the left and right waterproof fastening sheets 30L, 30R are sewn together with the encased stretchable material 5 to form the waterproof region 13E of the leg opening edge.

[0041] The underlayment 10U is made up of two layers, with the inner surface of the main fabric 10Ua waterproofed as shown in FIG. 2(b), or with a waterproof fabric 10Ub laminated on the inside of the main fabric 10Ua as shown in FIG. 3(b). Therefore, the waterproof areas 13E at the leg opening edges provided at the ends of the left and right waterproof areas 13L, 13R of the water-absorbent area 12, together with the left and right waterproof areas 13L, 13R, can doubly prevent bodily fluids such as menstrual blood and urine from leaking laterally out of the crotch 10 from the edges of the water-absorbent area 12 (water-absorbent member 20).

[0042] Furthermore, as described above, the water-absorbent sanitary shorts of this embodiment have a common stretchable material 5 sewn to the leg opening edges 4 formed by the crotch 10 and the leg opening edges of the front and back bodies 2 and 3. As described above, the leg opening edges 14 of the crotch 10 are formed with waterproof regions 13E at the leg opening edges, but the leg opening edges of the front and back bodies 2 and 3 are flat-sewn with elastic material 5 such as rubber on the skin side. Elastic material 5 such as rubber does not easily come off, improving the fit around the leg openings of the wearer, and flat-sewn seams minimize thickness, making the water-absorbent sanitary shorts of this embodiment comfortable for the wearer.

[0043] The water-absorbent sanitary shorts according to the present invention have been described above, but the present invention is not limited to the above-mentioned embodiments and examples. The materials, composition, and type of the water-absorbent sanitary shorts according to the present invention are not particularly limited, and the dimensions and thickness can also be changed as appropriate.

[0044] In addition, the present invention can be implemented in various forms with various improvements, modifications, and changes made based on the knowledge of those skilled in the art without departing from the spirit of the present invention. [Industrial Applicability]

[0045] The water-absorbing sanitary shorts according to the present invention can be used by women to make their menstrual period safer and more comfortable, and can also be used by women who suffer from urinary incontinence to go out with peace of mind.
