Description

Technical Field

[0001] This invention relates to a pair of short underwear. Background Technology

[0002] Previously, there was a type of sanitary underwear known to hold absorbent pads such as menstrual pads or incontinence pads in place. However, since sanitary underwear itself does not have absorbent properties, it can sometimes leak menstrual blood or urine when the absorbent pad shifts, thus staining the clothes worn on the body.

[0003] In order to avoid soiling the clothes worn on the body, a type of short underwear is proposed that is formed by a layer of absorbent and waterproof sheets (see, for example, Patent Documents 1 and 2).

[0008] The problem that the invention aims to solve

[0009] However, if the entire body of the underwear is waterproofed, it can easily become stuffy and hot, causing discomfort to the wearer at times. Furthermore, if menstrual blood or other substances spread throughout the underwear, the wearer's body can easily become soiled.

[0010] The present invention aims to provide short underwear that can be worn comfortably.

[0011] Methods for solving problems

[0012] One aspect of the present invention is that a pair of short underwear (1) has a second crotch portion (3) provided on the inner side of the crotch portion (23) of the short underwear body (2), extending from the front end to the rear end of the crotch portion (23) and capable of wrapping an absorbent pad (C) with an adhesive surface (C3) around it. The second crotch portion (3) is an absorbent component with a multi-layer structure having at least an absorbent layer (31) and a waterproof layer (33) arranged sequentially from the inside. As the outermost layer of the second crotch portion (3), a pad retaining layer (34) is further provided, which is capable of attaching the adhesive surface (C3) of the absorbent pad (C). The pad retaining layer (34) is made of a material that has lower adhesion to the adhesive surface (C3) than the waterproof layer (33) and is easy to remove the absorbent pad (C).

[0018] Figure 4 This is a diagram showing the unfolded structure of the second crotch section. Detailed Implementation

[0019] Hereinafter, embodiments of the shorts of the present invention will be described with reference to the accompanying drawings. The structure described below is an example (representative example) of the present invention. The present invention is not limited thereto.

[0020] In the following explanation, "right" refers to direction X1 in the attached diagram, and "left" refers to direction X2. "Up" refers to direction Y1 in the attached diagram, and "down" refers to direction Y2. "Front" refers to direction Z1 in the attached diagram, and "back" refers to direction Z2. Furthermore, "inner side" refers to the side in contact with the wearer's skin, and "outer side" refers to the opposite side.

[0021] Figure 1 The short underwear 1 represents the embodiment of this invention.

[0022] The short underwear 1 includes a short underwear body 2 and elastic bands 41 and 42. The short underwear body 2 is a fabric body that is provided at the top and lower left and right sides for openings at the waist and legs of the wearer, respectively.

[0023] An elastic band 41 is sewn around the opening at the top of the main body 2 of the short underwear. An elastic band 42 is sewn around the opening at the bottom of the main body 2 of the short underwear. The elastic bands 41 and 42 make the short underwear 1 easy to fit the wearer's waist and the top of the legs.

[0024] The main body 2 of the short underwear consists of a front part 21, a back part 22, and a crotch part 23. Although in this embodiment, the front part 21, the back part 22, and the crotch part 23 are each composed of different fabric bodies, and the main body 2 of the short underwear is formed by sewing the various fabric bodies together, each part may also be composed of a single fabric body.

[0025] For the front part 21 and the back part 22, their left and right ends are sewn together to cover the area around the wearer's waist. The front end of the crotch part 23 is sewn together with the lower end of the front part 21. In addition, the rear end of the crotch part 23 is sewn together with the lower end of the back part 22. The crotch part 23 covers the wearer's groin area.

[0026] Figure 2 , represents a top view of the inner side of the crotch 23. Figure 3 for, Figure 2 A sectional view at line II in the diagram. Figure 4 This is the unfolded diagram of the second crotch section 3.

[0027] The crotch 23 has a double structure, and a second crotch 3 is provided on the inner side of the fabric body of the crotch 23.

[0028] In this embodiment, the fabric of the crotch area 23 consists of two layers: an outer layer material 23A and a lining material 23B. The lining material 23B, which is disposed on the inner side, is waterproof.

[0029] The front-to-back length of the second crotch portion 3 is the same as that of the crotch portion 23, and the positions of its front and rear ends are consistent with those of the crotch portion 23. On the other hand, the left-to-right width of the second crotch portion 3 is shorter than that of the crotch portion 23, and its left and right ends are located closer to the center compared to the crotch portion 23.

[0030] The second crotch section 3 extends from the front end of the crotch section 23 to the rear end. In other words, although the front and rear ends of the second crotch section 3 are fixed to the main body of the short underwear 2, the parts other than the front and rear ends are separated from the main body of the short underwear and are suspended.

[0031] Therefore, an absorbent pad C with protective wings can be wrapped around the second crotch area 3. For example, the absorbent pad C is a sanitary napkin for absorbing menstrual blood or an absorbent pad for absorbing urine.

[0032] When the absorbent pad C is placed, the main body C1 of the absorbent pad C is positioned on the second crotch 3. The protective wings C2 are folded at the left and right ends of the second crotch 3, thereby being inserted between the second crotch 3 and the crotch 23.

[0033] The absorbent pad C has an adhesive surface C3. The absorbent pad C is arranged with the adhesive surface C3 facing the second crotch portion 3. By attaching the adhesive surface C3 of the main body C1 and the wing C2 to the surface of the second crotch portion 3, the absorbent pad C can be fixed to the underwear 1.

[0034] The second crotch section 3 is an absorbent component with a multi-layered structure. Therefore, even without the absorbent pad C, the second crotch section 3 can absorb fluids such as menstrual blood or urine excreted from the wearer's body. Since the second crotch section 3 is a separate component from the main body 2 of the underwear, it absorbs fluids, thus preventing soiling of the main body 2 of the underwear.

[0035] When the absorbent pad C is placed, the second crotch area 3 can also absorb liquid that leaks from the absorbent pad C due to positional displacement, thereby preventing contamination of the underwear body 2.

[0036] From the viewpoint of preventing leakage, the absorbency of the second crotch portion 3 is preferably 5 ml or more, more preferably 10 ml or more. From the viewpoint of reducing discomfort caused by water retention, the absorbency is preferably 60 ml or less, more preferably 50 ml or less.

[0037] In the second crotch area 3, an absorbent layer 31 and a waterproof layer 33 are arranged sequentially from the inside. In this embodiment, a water-retaining layer 32 is also arranged between the absorbent layer 31 and the waterproof layer 33. Liquid discharged from the body is absorbed by the absorbent layer 31 and further absorbed by the water-retaining layer 32. Since the movement of the absorbed liquid from the water-retaining layer 32 towards the crotch area 23 is blocked by the waterproof layer 33, it is retained in the water-retaining layer 32.

[0038] As the absorbent layer 31, a fabric such as a knitted or woven fabric with absorbency can be used. From the viewpoint of the feel when in contact with the skin, a soft and stretchy fabric such as a double rib knit or a plain knit is preferred. The material of the absorbent layer 31 is not particularly limited and can be either a synthetic fiber such as polyester or a natural fiber such as cotton.

[0039] As the water-retaining layer 32, a nonwoven fabric or similar material with both water absorption and water retention properties can be used. Preferably, a superabsorbent fiber, which has a faster water absorption rate and a larger water absorption capacity compared to conventional fibers such as polyester, is used as the material for the water-retaining layer 32. The nonwoven fabric can also be formed from a blend of fibers such as acrylic fibers or polyester fibers.

[0040] The thickness of the water-retaining layer 32 can be determined based on factors such as the target water absorption of the second crotch area 3. From the viewpoint of water retention, the thickness of the water-retaining layer 32 is preferably 0.5 mm or more, more preferably 1.5 mm or more. From the viewpoint of reducing discomfort when wearing the garment, the thickness is preferably 10 mm or less, more preferably 7 mm or less, and even more preferably 4 mm or less.

[0041] From the viewpoint of preventing stuffiness, the waterproof layer 33 is preferably not only waterproof but also breathable.

[0042] In this embodiment, the waterproof layer 33 has a nonwoven fabric 332, identical to the water-retaining layer 32, laminated inside the resin film 331, which is both waterproof and permeable. Since the waterproof layer 33 also has water absorption and water retention properties, the water absorption of the second crotch 3 can be increased.

[0043] In the second crotch area 3, a padding retaining layer 34 is further provided as the outermost layer compared to the waterproof layer 33. On the outermost padding retaining layer 34, the adhesive surface C3 of the wing C2 to which the absorbent pad C is attached is attached.

[0044] Compared to the waterproof layer 33, the padding retaining layer 34 has lower adhesion to the adhesive surface C3 of the absorbent pad C, thus allowing the absorbent pad C to be easily removed. A smooth woven fabric can be used as such a padding retaining layer 34.

[0045] As described above, the waterproof layer 33, which uses a waterproof resin film or the like, has a high degree of adhesion to the adhesive used on the bonding surface C3 of the absorbent pad C. However, because a pad retaining layer 34 is present between the waterproof layer 33 and the absorbent pad C, the bonding surface C can be peeled off with a smaller peeling force, thereby making it easier to put on and take off the absorbent pad C.

[0046] Compared to the stretchy fabric used in the main body 1 or crotch area 23 of the shorts, the smooth woven fabric described above has lower adhesion to the bonding surface C3 of the padding retaining layer 34, making it easier to peel off the bonding surface C3. Therefore, it is less likely to cause the fabric of the padding retaining layer 34 to loosen or pill due to the peeling force.

[0047] Preferably, each layer of the second crotch portion 3 has antibacterial or bacteriostatic properties. In particular, it is preferable that the absorbent layer 31 in contact with the skin and the water-retaining layer 32 for retaining liquid have antibacterial or bacteriostatic properties. The antibacterial or bacteriostatic properties can be imparted by processing an antibacterial agent or bacteriostatic agent onto the substrate of each layer.

[0048] Each layer of the second crotch portion 3 is sewn onto the outer periphery of the second crotch portion 3 using waterproof thread. The shorts 1 of this embodiment include waterproof bands 51 and 52 disposed on the outer periphery of the second crotch portion 3. Each layer of the second crotch portion 3 is sewn together with the waterproof bands 51 and 52, thereby providing seam lines 61 and 62.

[0049] A waterproof band 51 is positioned at the left and right ends of the second crotch portion 3. The waterproof band 51 is folded in such a way that it clamps the left and right ends of the second crotch portion 3 and covers their end faces. A suture 61 is formed by sewing the folded waterproof band 51 to the second crotch portion 3 using a waterproof thread.

[0050] The waterproof band 52 is disposed at the front and rear ends of the second crotch 3. The waterproof band 52 extends further to the left and right from the second crotch 3, and is also disposed at the front and rear ends of the crotch 23 of the short underwear body 2.

[0051] The waterproof tape 52 is folded in such a way that it sandwiches and covers the front and rear ends of the second crotch 3 and crotch 23. The suture 62 is formed by sewing the folded waterproof tape 52 onto the second crotch 3 and crotch 23 using a waterproof thread.

[0052] Waterproof strips 51 and 52 are used to suppress the outflow of liquid from the end faces of the second crotch 3 and crotch 23. Because waterproof thread is used in the stitching, liquid that expands outwards can easily seep back towards the center, thus making it easier to suppress the outflow of liquid towards the periphery.

[0053] As waterproof tapes 51 and 52, for example, binding tapes made of waterproof fabric can be used.

[0054] The absorbent layer 31 and the water-retaining layer 32 are stitched together in a ring shape on the central side relative to the outer periphery of the second crotch portion 3 by a waterproof thread, thus providing a stitch line 63. The waterproof thread allows liquid that wants to flow out to the outer side to seep back, thereby facilitating its return to the central side.

[0055] The water-retaining layer 32 has a smaller area compared to the entire area of ​​the second crotch 3, and is disposed on the central side of the second crotch 3. The seam 63 is formed by sewing the absorbent layer 31 and the water-retaining layer 32 together by using a waterproof thread along the outer periphery of the water-retaining layer 32.

[0056] By using the peripheral sutures 61 and 62 and the central suture 63, the wall of the waterproof liner that runs through the thickness direction can be doubled. Although liquid adheres to the vicinity of the center of the second crotch 3 and is absorbed by each layer, spreading outwards, this diffusion can be blocked in stages by the double walls. Thus, leakage of liquid from the peripheral side can be effectively suppressed.

[0057] The waterproof thread is not specifically limited; threads made of waterproof resin or coated with waterproof resin can be used. The waterproof threads of each suture 61 to 63 can be of the same type or have different degrees of waterproofness.

[0058] As described above, according to this embodiment, a second crotch portion 3 is provided on the inner side of the crotch portion 23 of the short underwear body 2. The second crotch portion 3 is an absorbent component with a multi-layer structure.

[0059] Even in the event of accidental discharge without the absorbent pad C, the second crotch area 3 can adequately absorb menstrual blood or urine. This prevents leakage from the underwear 1, thus avoiding staining of the clothes worn underneath.

[0060] Furthermore, the second crotch area 3 can accommodate an absorbent pad C around it, and has a pad retaining layer 34 on the outermost layer. Since the pad retaining layer 34 makes it easy to peel off the adhesive surface C3 of the absorbent pad C, it provides a pair of shorts 1 that are easier to put on and take off with the absorbent pad C.

[0061] When the absorbent pad C is in place, any liquid leaking from the absorbent pad C is also retained by the second crotch area 3, thus preventing it from spreading into the entire panty 1. Therefore, panty 1 can be provided that does not stain the clothes worn on the body and can be worn comfortably.

[0062] The second crotch area 3, which uses knitted or woven fabrics, non-woven fabrics, etc. instead of polymers, can also be washed, thus allowing the short underwear 1 to be reused.

[0063] Although preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments and can be modified in various ways.

[0064] For example, although the suture 63 is arranged in a ring shape along the outer periphery of the water-retaining layer 32, waterproof threads can also be used to suture the various layers such as the absorbent layer 31 in the outer or inner regions of this ring shape, thereby further providing one or more sutures. The waterproof threads enable the flow of liquid from the central side to the outer periphery to be blocked in multiple stages, thereby easily reducing liquid leakage.

[0065] The shape of the suture is not particularly limited; it can be either circular or linear. For example, it can be configured such that two linear sutures extending forward and backward sandwich the central portion in the region inside the suture 63.

[0066] Furthermore, the multi-layer structure of the second crotch 3 is not limited to the structure described above. For example, multiple layers may be provided. Since the water-retaining layer 32 is also absorbent, it may be configured in the following order from the inside: water-absorbing layer 31, water-retaining layer 32, water-absorbing layer 31, water-retaining layer 32, and waterproof layer 33.

[0067] The second crotch area 3 may also have other layers besides those mentioned above. For example, a nonwoven fabric treated with a hydrophilic agent may be provided as a backflow prevention layer between the absorbent layer 31 and the water-retaining layer 32. Such a nonwoven fabric delivers liquid from the absorbent layer 31 to the water-retaining layer 32 at a faster speed, thereby suppressing the backflow of liquid from the water-retaining layer 32 to the absorbent layer 13.
