Description

Technical Field

[0001] The present invention relates to a reusable water-absorbent pad that is worn on the crotch part of panties.

Background Art

[0002] Patent Document 1 discloses an absorbent article aimed at providing an absorbent article that does not swell before use and can be easily deformed into a convex shape on the skin side of the wearer during use.

[0003] The absorbent article includes a vertically long absorbent body having a liquid-retaining absorbent layer and a liquid-impermeable back layer, and a pair of wing parts provided on both sides of the absorbent body. Each of the wing parts has a displacement preventing means on the non-skin contact surface side in the vicinity of the absorbent body, and has a fastening means for joining the wing parts to each other. When the wing parts are joined to each other and fixed to the crotch part of panties, the central part in the width direction of the crotch part and both wing parts are made separable.

[0004] Such absorbent articles have high absorbency of body fluids because they incorporate polymer absorbents and are suitably used for menstrual pads, urine pads, etc. However, there is a problem that they are disposable and have a high environmental load such as causing environmental pollution when incinerated later.

[0005] [[ID=​​​​​​​​​​​​​​​​​Utility Model Registration No. 3083424 Gazette [Overview of the project] [Problems that the invention aims to solve]

[0007] However, although the absorbent pad described in Patent Document 2 can be reused by washing, it was designed to be fixed to the inside of incontinence pants via hook-and-loop fasteners placed at the corners of the detachable absorbent pad. As a result, when the absorbent pad was not attached, the hook-and-loop fasteners on the inside of the incontinence pants caused discomfort to the skin, making it impossible to wear the pants without the detachable pad.

[0008] When using adhesive tape, similar to that used for disposable sanitary napkins, to secure reusable absorbent pads to underwear, there is a problem in that the adhesive strength gradually decreases with repeated washing, making it impossible to secure them properly. Therefore, if snap buttons or hook-and-loop fasteners are used to secure the absorbent pads to underwear, the wearing comfort tends to be poor, as described in Patent Document 2.

[0009] Furthermore, in the case of an absorbent article described in Patent Document 1, where wing portions are extended outward in the width direction from the center of both edges along the longitudinal direction of the absorbent pad, and the wing portions are folded to the skin side of the absorbent pad, sandwiching the crotch area of ​​the shorts, and the overlapping portion of the wing portions is fixed with snap buttons or hook-and-loop fasteners instead of adhesive tape, there is a problem that the order in which the two wing portions are overlapped is fixed, so it is necessary to be mindful of the overlapping order when folding them, which makes handling cumbersome.

[0010] In view of the above-mentioned problems, the object of the present invention is to provide an absorbent pad that can be easily attached and detached, can be reused, and has excellent wearing comfort. [Means for solving the problem]

[0011] To achieve the above objective, the first characteristic configuration of the absorbent pad according to the present invention is a reusable absorbent pad that is attached to the crotch area of ​​shorts, comprising an absorbent body including a waterproof fabric piece that contacts the crotch area and an absorbent fabric piece that contacts the skin side, and a fixing part that fixes the absorbent body to the shorts when attached to the crotch area, wherein the fixing part is composed of a pair of wing pieces that extend outward in the width direction of the crotch area from the center of both side edges along the longitudinal direction of the absorbent body, with pile fabric that functions as a locking body on one side and lining fabric that functions as a locking body on the other side, and is configured so that when the wing pieces are folded away from the skin side with the crotch area in between, one pile fabric and the other lining fabric overlap and adhere closely to each other. Furthermore, the absorbent material is configured such that the outer edge of the absorbent fabric piece is joined to the inner edge of a water-repellent fabric piece of a predetermined width, and the outer edge of the water-repellent fabric piece and the outer edge of the waterproof fabric piece are joined together so that the water-repellent fabric piece of the predetermined width comes into contact with the skin, and the waterproof fabric piece is free from the absorbent fabric piece and the water-repellent fabric piece. It's at a single point.

[0012] With an absorbent body containing a waterproof fabric piece and a water-absorbing fabric piece positioned in the crotch area of ​​the shorts, a pair of wing pieces extend from the center of both side edges along the longitudinal direction of the absorbent body outward in the width direction of the crotch area. A pile fabric that functions as a locking body is provided on one side of each wing piece, and a pile fabric that functions as a locking body is provided on the other side. Therefore, when the wing pieces are folded away from the skin, sandwiching the crotch area, regardless of the order in which the pair of wing pieces are overlapped, one of the pile fabrics and the other pile fabric will overlap and adhere closely to each other.

[0013] Furthermore, among the absorbent materials, the outer edge of the absorbent fabric piece located on the skin side is joined to the inner edge of the water-repellent fabric piece, and the outer edges of the water-repellent fabric piece and the outer edges of the waterproof fabric piece are joined together so that a predetermined width of water-repellent fabric piece comes into contact with the skin side, and the waterproof fabric piece is separated from the absorbent and water-repellent fabric pieces. As a result, the water-repellent fabric piece ensures adequate breathability on the skin side, preventing stuffiness and providing a comfortable fit that is gentle on the skin. Even if bodily fluids leak from the edge of the absorbent fabric piece, it effectively prevents them from seeping into the crotch area, etc.

[0014] The second characteristic configuration is that, in addition to the first characteristic configuration described above, the pile fabric is arranged on one side of the wing piece that is made of absorbent fabric, and the pile fabric is arranged on one side of the wing piece that is made of waterproof fabric.

[0015] When pile fabric is placed on one side of the absorbent fabric and the lint fabric is placed on one side of the wing piece that is waterproof, the lint fabric on the wing surface comes into contact with the skin-side surface of the crotch area, creating a large frictional force. At the same time, the pile fabric surface on one side of the pair of wing pieces and the lint fabric on the other side overlap and adhere closely, so that the absorbent material placed in the crotch area does not move relative to the crotch area and is fixed in a stable position. When pile fabric is placed on one side of the absorbent fabric and the lint fabric is placed on one side of the wing piece that is waterproof, the lint fabric, which tends to attract dust and other debris, is folded inward when it overlaps with the pile fabric. As a result, the lint fabric, which may have dust and other debris attached to it, does not come into contact with the skin, making skin irritation, itching, and other problems less likely to occur. In addition, since dust and other debris attached to the lint fabric are hidden on the inside, it is also aesthetically pleasing.

[0016] The third characteristic feature is that, in addition to the second characteristic feature described above, the pile fabric is made of velour fabric.

[0017] By using velour fabric as the pile fabric, a pleasant feel against the skin can be achieved.

[0018] The fourth characteristic configuration is, in addition to any of the first to third characteristic configurations described above, The key feature is that one or more water-absorbing nonwoven fabrics are superimposed on the water-absorbing fabric piece, and the water-absorbing nonwoven fabrics are bonded together with the water-absorbing fabric piece to the inner edge of the water-repellent fabric piece, while being detachable from both the water-absorbing fabric piece and the waterproof fabric piece.

[0019] The amount of bodily fluid absorbed is appropriately ensured by the absorbent nonwoven fabric superimposed on the absorbent fabric piece between the absorbent fabric piece and the waterproof fabric piece. [Effects of the Invention]

[0020] As described above, the present invention makes it possible to provide an absorbent pad that can be easily attached and detached, can be reused, and has excellent wearing comfort. [Brief explanation of the drawing]

[0021] [Figure 1] (a) is an explanatory view of the water-absorbent pad according to the present invention as viewed from the skin side, and (b) is an explanatory view of the water-absorbent pad according to the present invention as viewed from the non-skin side [Figure 2] (a) is an explanatory view of the water-absorbent pad disposed in the crotch portion of the shorts as viewed from the non-skin side, and (b) is an explanatory view of the water-absorbent pad fixed to the crotch portion of the shorts as viewed from the non-skin side [Figure 3] (a) is an explanatory view of the water-absorbent pad according to the present invention as viewed from the skin side, and (b) is a cross-sectional view taken along the line A-A of FIG. 3(a) [Figure 4] (a) is a cross-sectional view of the fixing portion, (b) is a cross-sectional view of the fixing portion, (c) is a cross-sectional view of the fixing portion, and (d) is a cross-sectional view showing the close contact state

Mode for Carrying Out the Invention

[0022] Hereinafter, an example of the water-absorbent pad according to the present invention will be described based on the drawings In FIG. 1(a), the water-absorbent pad 10 as viewed from the skin surface side is shown, and in FIG. 1(b), the water-absorbent pad 10 as viewed from the non-skin surface side is shown In FIG. 2(a), the water-absorbent pad 10 disposed on the skin side of the crotch portion 2 of the shorts 1 and viewed from the non-skin side direction is shown, and in FIG. 2(b), the water-absorbent pad 10 in a state fixed to the crotch portion 2 is shown

[0023] The water-absorbent pad 10 is a water-absorbent pad that is worn and used in the crotch portion 2 of the shorts 1 and can be reused by cleaning after use. It includes a water-absorbing body 11 including a waterproof fabric piece 12 that abuts against the crotch portion 2 and a water-absorbent fabric piece 13 that abuts against the skin side, and a fixing portion 17 that fixes the water-absorbing body 11 to the shorts 1 in a state of being attached to the crotch portion 2. The length of the water-absorbing body 11 in the longitudinal direction is set to be, for example, around 200 mm, and the length of the water-absorbing body 11 in the short direction is set to be, for example, 90 mm. Note that the size of the water-absorbing body 11 is not limited to this value and can be set as appropriate

[0024] As shown in Figures 3(a) and 3(b), two absorbent nonwoven fabrics 14 and 15 are superimposed between the waterproof fabric piece 12 and the absorbent fabric piece 13 that constitute the absorbent body 11. Note that the number of absorbent nonwoven fabrics 14 and 15 does not have to be two; it may consist of one or more pieces, and the thickness of each absorbent nonwoven fabric can be appropriately set according to the target amount of water absorption.

[0025] The outer edges of the absorbent fabric piece 13 and the absorbent nonwoven fabrics 14 and 15 are joined by sewing to the inner edges of the water-repellent fabric piece 16 of a predetermined width, so that the periphery of the absorbent fabric piece 13 and the absorbent nonwoven fabrics 14 and 15 are surrounded by four water-repellent fabric pieces 16, and the boundaries of the four water-repellent fabric pieces 16 are also joined by sewing. The outer edges of the water-repellent fabric piece 16 and the outer edges of the waterproof fabric piece 12 are joined to each other by sewing. The predetermined width can be set to around 20 mm, for example, 15 mm to 25 mm.

[0026] Although an example has been described in which the water-repellent fabric pieces 16 are composed of four pieces, the configuration is not limited to this. The configuration is not limited to joining the water-repellent fabric pieces 16 so as to surround the absorbent fabric pieces 13 and the absorbent nonwoven fabrics 14 and 15. For example, the configuration may consist of two water-repellent fabric pieces 16, without surrounding the edges of the absorbent fabric pieces 13 and the absorbent nonwoven fabrics 14 and 15, and the water-repellent fabric pieces 16 may be joined only to the edges along the longitudinal direction. Alternatively, the water-repellent fabric piece 16 may consist of a single annular piece of fabric. The water-repellent fabric pieces 16 should be appropriately placed in positions that prevent leakage of bodily fluids from the edges of the absorbent fabric pieces 13 and the absorbent nonwoven fabrics 14 and 15, in accordance with the shape, size, and location of the absorbent body 11 where the amount of bodily fluid absorbed is greatest.

[0027] The waterproof fabric piece 12 is free from the water-absorbing fabric piece 13 and the water-repellent fabric piece 16, except at the sewing site with the water-repellent fabric piece 16. In addition, the water-absorbing fabric piece 13 and the water-absorbing nonwoven fabrics 14 and 15 are superimposed so as to be free from each other, except at the sewing site with the water-repellent fabric piece 16.

[0028] Of the absorbent material 11, the outer edge of the absorbent fabric piece 13 located on the skin side is joined with a water-repellent fabric piece 16, and the waterproof fabric piece 12 is separated from the absorbent fabric piece 13 and the water-repellent fabric piece 16. This effectively prevents bodily fluids from leaking from the edge of the absorbent fabric piece 13 and soaking into the crotch area 2, and also ensures adequate breathability, resulting in a comfortable fit that is gentle on the skin.

[0029] Furthermore, the absorbent nonwoven fabrics 14 and 15 placed between the absorbent fabric piece 13 and the waterproof fabric piece 12 ensure that the amount of bodily fluids absorbed is appropriately ensured. Polyester-based highly absorbent fibers can be used as the absorbent nonwoven fabrics 14 and 15, and nonwoven fabrics treated with ammonia deodorizing processing can be suitably used.

[0030] The waterproof fabric piece 12 is made of a weft-knitted fabric formed from a blend of cotton yarn and synthetic fiber yarn such as polyester yarn, and a waterproof layer 12A is formed on the skin side with a breathable waterproof laminate coating, thereby ensuring breathability and waterproofness.

[0031] Similarly, the absorbent fabric piece 13 is made of a weft-knitted fabric knitted from a blend of cotton yarn and synthetic fiber yarn such as polyester yarn. Bodily fluids such as urine and menstrual blood that soak into the absorbent fabric piece 13 are absorbed by the absorbent nonwoven fabrics 14 and 15, which have been treated with ammonia deodorizing processing. Note that the waterproof fabric piece 12 and the absorbent fabric piece 13 can be any stretchable woven fabric and are not limited to weft-knitted fabrics. Furthermore, the fibers constituting the woven fabric are not limited to a blend of cotton yarn and synthetic fiber yarn; they may be cotton yarn only or synthetic fiber yarn only. In addition, regenerated fiber yarns such as rayon and cupro may be used instead of cotton yarn.

[0032] The fixing portion 17 extends from the center of both side edges along the longitudinal direction of the absorbent body 11 outward in the width direction of the crotch portion 2, and consists of a pair of arc-shaped wing pieces 17A and 17B, with pile fabric 18 which functions as a locking body on one side and lint fabric 19 which functions as a locking body on the other side.

[0033] As shown in Figure 2(b), by folding the wing pieces 17A and 17B toward the skin side with the crotch area 2 in between, one pile fabric 18 and the other pile fabric 19 are configured to overlap and adhere closely. Regardless of the overlapping order of the wing pieces 17A and 17B, the pile fabric 18 and the pile fabric 19 can face each other and adhere closely, so there is no need to be conscious of the folding order of the wing pieces 17A and 17B for fixing.

[0034] In this embodiment, the pile fabric 19 is arranged on the side of the wing pieces 17A and 17B that constitute the water-absorbing body 11, on the side of the waterproof fabric piece 12, and the pile fabric 18 is arranged on the side of the water-absorbing fabric piece 13. Figure 4(a) shows a cross-section of the pile fabric 19. The pile fabric 19 is made of a base fabric 19A woven using cotton yarn or synthetic fiber yarn such as polyester yarn to create pile on one side, and a velour fabric is used in which the pile 19B is formed by cutting the pile formed on the surface of the base fabric 19A.

[0035] While not particularly limited, the velour fabric is woven using ultrafine fiber yarn that is 1 / 100th the thickness of the hook commonly used as hook-and-loop fasteners (approximately 3 denier), resulting in a very pleasant texture with a pile density of approximately 100,000 threads per inch.

[0036] Figure 4(b) shows a cross-section of the pile fabric. The pile fabric 18 is composed of a base fabric 18A woven using cotton yarn or synthetic fiber yarn such as polyester yarn, so that pile is woven on one side, and pile 18B is formed on the surface of the base fabric 18A.

[0037] Although not particularly limited, the pile fabric 18 is woven using ultrafine fiber yarn that is 1 / 200th the thickness of the pile commonly used as hook-and-loop fasteners (approximately 0.1 denier), and is a fabric in which a pile density of approximately 1,400,000 threads per inch is formed.

[0038] The type and thickness of the fibers used in the fabrics that make up the pile fabric 18 and the raised pile fabric 19 are not limited to the examples described above, and it is also possible to use recycled fibers or the like as appropriate instead of cotton or synthetic fibers.

[0039] As shown in Figure 4(c), the wing pieces 17A and 17B have pile fabric 18 on the wing surface facing the absorbent fabric piece 13 and pile fabric 19 on the wing surface facing the waterproof fabric piece 12. Therefore, as shown in Figure 4(d), regardless of which wing piece 17A or 17B is in contact with the shorts 1, the pile fabric 19 will be in contact with the skin-side surface of the crotch area. This prevents the pile fabric 19, which is prone to attracting dust and other debris, from coming into contact with the skin, thus reducing the likelihood of skin irritation, itching, and other problems. Furthermore, dust and other debris that adhere to the pile fabric are hidden on the inside, resulting in a superior aesthetic appearance.

[0040] Furthermore, even if the close contact (engagement) between the pile fabric 18 and the raised pile fabric 19 is released and the wing pieces 17A and 17B hang down, the surface that touches the wearer's inner thigh is made of soft, skin-friendly pile fabric 18, so there is less irritation to the skin and no discomfort.

[0041] In the embodiment described above, an example was explained in which the pile fabric 19 was arranged on the waterproof fabric piece 12 side of the wing pieces 17A and 17B that constitute the absorbent body 11, and the pile fabric 18 was arranged on the absorbent fabric piece 13 side. However, small pieces of pile fabric 18 and pile fabric 19 may be arranged in a staggered pattern on both sides of the wing pieces 17A and 17B. In this case as well, regardless of the overlapping order of the wing pieces 17A and 17B, the pile fabric 18 and pile fabric 19 can face each other and be in close contact, so there is no need to be conscious of the folding order of the wing pieces 17A and 17B for fixing. Furthermore, the frictional force between the surface of the wing piece 17A and 17B on the waterproof fabric piece 12 side and the main fabric of the shorts may be set to be relatively smaller than the frictional force between the surface of the wing piece 17A and 17B on the waterproof fabric piece 12 side and the main fabric of the shorts. In that case, the waterproof fabric piece 12 side of the wing surface comes into contact with the skin-side surface of the crotch area, creating a large frictional force that fixes it in a stable position.

[0042] The embodiments described above are merely examples of the present invention, and the technical scope of the present invention is not limited by this description. [Industrial applicability]

[0043] The absorbent pad according to the present invention can be reused after cleaning and is a comfortable absorbent pad that can be easily attached to and detached from shorts, making it suitable for use by a wide range of generations. [Explanation of symbols]
