[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0019] Fig. 1 is a perspective view showing the configuration of light incontinence pad 1, which is an absorbent pad according to an embodiment of the present invention, Fig. 2 is a plan view showing the configuration of light incontinence pad 1 according to an embodiment of the present invention, Fig. 3 is a bottom view showing the configuration of light incontinence pad 1 according to an embodiment of the present invention, Fig. 4 is a front view showing the configuration of light incontinence pad 1 according to an embodiment of the present invention, and Fig. 5 is a side view showing the configuration of light incontinence pad 1 according to an embodiment of the present invention. However, Fig. 1 schematically shows the state in which light incontinence pad 1 is three-dimensionally deformed to fit the body shape of a user.

[0020] Light incontinence pad 1 is attached to the underwear of the female user and positioned between the female's body and the underwear. Light incontinence pad 1 mainly comprises pad body 10, sealing part 20 provided so as to seamlessly cover the periphery of pad body 10, and band part 30 for attaching light incontinence pad 1 to the underwear.

[0021] The pad body 10 has an oval outer shape in a plan view, and has a laminated structure consisting of a contact part 11 that fixes the pad body 10 at a position corresponding to the surface of the body including the user's private parts when the light incontinence pad 1 is in use and comes into contact with the private parts, a covering part 12 made of a waterproof material and located on the opposite side to the contact part 11, closer to the underwear, and an absorbing part 13 made of a water-absorbent material and sandwiched between the contact part 11 and the covering part 12.

[0022] In the following description, the longitudinal direction of the pad body 10 is defined as the longitudinal direction (front-to-back direction), the direction perpendicular to the longitudinal direction in a planar view is defined as the short direction (left-to-right direction), and the stacking direction of the contact portion 11, the absorbing portion 13, and the covering portion 12 is defined as the up-down direction.

[0023] FIG. 6 is an exploded perspective view showing a schematic configuration of the pad body 10, including a cross-sectional view taken along line AA in FIG.

[0024] In the pad body 10, the contact portion 11 is composed of a central portion 11a located in the center, and a left portion 11b and a right portion 11c adjacent to the left and right of the central portion 11a. Each of the central portion 11a, the left portion 11b, and the right portion 11c is composed of a base fabric. In the following description, the central portion 11a, the left portion 11b, and the right portion 11c are each composed of a single piece of fabric, but they may also be composed of a laminate of multiple pieces of fabric. Furthermore, each of the central portion 11a, the left portion 11b, and the right portion 11c may be composed entirely or partially of a single piece of fabric. Furthermore, it is preferable to use a cotton woven fabric as the fabric material.

[0025] The central portion 11a corresponds to the entire planar shape of the pad body 10 and is made of a single piece of base cloth. The left side portion 11b extends along the longitudinal direction of the periphery of the left side of the pad body 10, and is made of a single piece of base cloth folded at fold 11bF toward the central portion 11a, resulting in a shape that is bent in a generally inverted V-shape in cross section when viewed from the front. The right side portion 11c extends along the longitudinal direction of the periphery of the right side of the pad body 10, and is made of a single piece of base cloth folded at fold 11cF toward the central portion 11a, resulting in a shape that is bent in a generally V-shape in cross section when viewed from the front.

[0026] In the contact portion 11, the left portion 11b is layered on the left edge of the central portion 11a, and the right portion 11c is layered on the right edge of the central portion 11a. As a result, the left portion 11b and the right portion 11c of the contact portion 11 are thicker than the central portion 11a, forming an inverted concave shape in cross section when viewed from the front. As a result, the contact portion 11 is able to conform to the shape of the private parts of the female wearer and has improved liquid absorption properties.

[0027] Like the central portion 11a, the absorbent portion 13 is a portion that corresponds to the entire planar shape of the pad body 10. The absorbent portion 13 is preferably made of padding made of a water-absorbent material such as Belloasis (trademark), which is used in incontinence underwear. The absorbent portion 13 is preferably thicker than the contact portion 11 and the covering portion 12. Furthermore, the absorbent portion 13 is preferably such that the front and back surfaces of the padding (not shown) are covered with a woven fabric made of water-absorbent synthetic fiber.

[0028] Like the central portion 11a, the covering portion 12 is a portion that corresponds to the entire planar shape of the pad body 10. The covering portion 12 is preferably obtained by weaving synthetic fibers such as polyester in a plain weave. In addition, the covering portion 12 is preferably thinner than the contact portion 11.

[0029] The sealing portion 20 is a thin, strip-shaped member that is wrapped around the pad body 10 so as to cover the outline of the pad body 10 in a plan view, forming an oval, annular outer shape. The sealing portion 20 is preferably made of a woven fabric of a water-repellent synthetic fiber such as nylon or polyester, and more preferably made of the same material as that used for the covering portion 12.

[0030] Next, the stitching state of the pad body 10 and the sealing portion 20 will be described with reference to Fig. 7. Fig. 7 is a cross-sectional view of the essential parts in region R in Fig. 2 taken along a line parallel to line AA in the figure, and also shows the cross-sectional shape of the sealing portion 20.

[0031] The contact part 11, the absorbent part 13 and the covering part 12 are layered in this order from the part closest to the user's body surface.

[0032] The sealing portion 20 is formed by sewing the periphery of the laminated structure of the contact portion 11, the absorption portion 13, and the covering portion 12 with four-fold piping, so that the sealing portion 20 seals the entire peripheral edge of the pad body 10 and the periphery including that edge as a whole.

[0033] A specific description will be given below. In the sealing portion 20, the band main body 21, which is the main part of the band, covers from the first peripheral surface 11S, which is the surface of the contact portion 11 closer to the peripheral edge, the edge 11cE of the right side portion 11c of the contact portion 11, the edge 11aE of the central portion 11a, the edge 13E of the absorbing portion 13, and the edge 12E of the covering portion 12, and wraps around to the second peripheral surface 12S, which is the surface of the covering portion 12 closer to the peripheral edge, to integrally cover these.

[0034] Furthermore, in the sealing part 20, the contact portion with the first peripheral edge surface 11S of the contact part 11 forms a first edge 21a formed by folding back one edge in the width direction of the band body 21 from the center toward the edge. Similarly, the contact portion with the second peripheral edge surface 12S of the covering part 12 forms a second edge 21b formed by folding back the other edge in the width direction of the band body 21 from the center toward the edge.

[0035] At the first edge 21a, one edge of the band body 21 slides inward to contact the first peripheral surface 11S, thereby forming a first double portion 21aT where the band body 21 overlaps twice. Similarly, at the second edge 21b, the other edge of the band body 21 slides inward to contact the second peripheral surface 12S, thereby forming a second double portion 21bT where the band body 21 overlaps twice.

[0036] The first double portion 21aT of the first edge portion 21a and the second double portion 21bT of the second edge portion 21b, and the peripheral portions of the contact portion 11, the absorbent portion 13 and the covering portion 12, including the edge ends 11cE and 11aE, the edge end 13E and the edge end 12E sandwiched between the first edge portion 21a and the second edge portion 21b, are sewn together at a constant pressure by a suture 40 that passes through from the first double portion 21aT to the second double portion 21bT, thereby fixing the stacked state of the pad main body 10 and integrally sealing the edge of the pad main body 10 by the sealing portion 20.

[0037] By sewing the suture 40, the first edge 21a forms a first curved surface 21aC in which a portion of the first double portion 21aT on the central side of the contact portion 11 bulges out and curves to protrude toward the center of the contact portion 11. Similarly, the second edge 21b forms a second curved surface 21bC in which a portion of the second double portion 21bT on the central side of the covering portion 12 bulges out and curves to protrude toward the center of the covering portion 12.

[0038] 6, the stitching positions of the pad body 10 with the suture thread 40 in a plan view are shown as stitching lines 10x in each of the contact portion 11, the absorbent portion 13, and the covering portion 12. The suture thread 40 is preferably, for example, a sewing thread that has been treated to be water repellent.

[0039] In the above explanation with reference to Figure 7, the configuration of the right side 11c of the contact portion 11 was used as an example, but the same applies to the left side 11b of the contact portion 11, which is the left side of the pad main body 10, and to the front and rear sides of the pad main body 10, where the contact portion 11 is formed only by the central portion 11a.

[0040] The pad body 10 has its peripheral edge sealed with the sealing portion 20 and sewn with four-fold piping, forming a curved, bowl-shaped outer shape with the contact portion 11 side concave and the covering portion 12 side convex, as shown in Figures 4 and 5. This allows the contact portion 11 to better conform to the shape of the user's private parts, improving its liquid-absorbing effect.

[0041] The band portion 30 is a member provided so as to be able to cross the contact portion 11 along the short direction of the light incontinence pad 1 in a plan view, and has a strip-shaped right band 31a provided on the right edge of the pad body 10 and a strip-shaped left band 31b provided on the left edge of the pad body 10. A concave snap button 32a is provided at the tip of the right band 31a, and a convex snap button 32b is provided at the tip of the left band 31b. The concave snap button 32a and the convex snap button 32b are fastened detachably, and with the concave snap button 32a and the convex snap button 32b fastened, the right band 31a and the left band 31b are connected with their ends overlapping, and the band portion 30 has a circular outer shape.

[0042] In the light incontinence pad 1 having the above-described configuration, the light incontinence pad 1 corresponds to the absorbent pad and light incontinence pad of the present invention, the pad main body 10 corresponds to the pad main body of the present invention, the contact portion 11 corresponds to the contact portion of the present invention, and the sealing portion 20 corresponds to the sealing portion of the present invention. Also, the covering portion 12 corresponds to the covering portion of the present invention, the absorbent portion 13 corresponds to the absorbent portion of the present invention, and the band portion 30 corresponds to the band portion of the present invention. Also, the fold 11bF of the left side portion 11b and the fold 11cF of the right side portion 11c of the contact portion 11 each correspond to the folded end of the present invention.

[0043] The light incontinence pad 1 of this embodiment having such a configuration is characterized in that the pad body 10 having a laminated structure of a contact portion 11, an absorbent portion 13 and a covering portion 12 is sealed by a sealing portion 20.

[0044] That is, the edges of the pad body 10 are exposed as the edges of the contact portion 11, absorbent portion 13, and covering portion 12, and the waterproof sealing portion 20 seals the first edge portion 21a and second edge portion 21b and the peripheral edges of the contact portion 11, absorbent portion 13, and covering portion 12 using the first edge portion 21a and second edge portion 21b and the band body 21. As a result, even if urine or other liquids absorbed from the contact portion 11 and absorbent portion 13 reach the edges of the pad body 10, they are covered by the sealing portion 20 and are prevented from leaking to the outside. The contact portion 11, absorbent portion 13, and covering portion 12 that make up the pad body 10 are all made of cloth and can be reused by washing.

[0045] Therefore, a light incontinence pad that can be used repeatedly and has excellent leak-proof properties can be obtained.

[0046] Furthermore, in the light incontinence pad 1 of this embodiment, the sealing part 20 has a band body 21 that integrally covers the edge of each of the contact part 11, the absorbent part 13, and the covering part 12 of the pad body 10, a first peripheral surface 11S that is the surface of the contact part 11 near the periphery, and a second peripheral surface 12S that is the surface of the covering part 12 near the periphery, and the contact part of the band body 21 with the first peripheral surface 11S is folded back from the center side of the contact part 11 to the edge side, forming a double overlap. The contact portion of the band body 21 with the second peripheral surface 12S forms a second edge 21b having a second double portion 21bT that is folded back from the center side of the covering part 12 to the edge side and overlaps twice, and the first double portion 21aT of the first edge 21a, the pad body, and the second double portion 21bT of the second edge 21b are sewn together.

[0047] As a result, even if urine or other liquid leaking onto the contact portion 11 before reaching the absorbent portion 13 reaches the periphery of the contact portion 11, it is blocked by the first edge portion 21a of the sealing portion 20, preventing leakage toward the edge.

[0048] In addition, the light incontinence pad 1 of this embodiment is characterized in that the cross-section of the first double portion 21aT of the first edge portion 21a of the sealing portion 20 forms a first curved surface 21aC protruding toward the center of the contact portion 11, and the cross-section of the second double portion 21bT of the second edge portion 21b forms a second curved surface 21bC protruding toward the center of the covering portion 12.

[0049] As a result, even if urine or other liquid leaking onto the contact part 11 side before reaching the absorbent part 13 reaches the periphery of the contact part 11, it is retained and blocked in the gap formed between the first curved surface 21aC and the surface of the contact part 11, and is prevented from returning to the center of the contact part 11. Therefore, it is possible to maintain a comfortable fit for the user.

[0050] Furthermore, the cross section of the first double portion 21aT of the first edge 21a of the sealing portion 20 forms a first curved surface 21aC that protrudes toward the center of the contact portion 11, which has the following effect: the first edge 21a is the part that comes into direct contact with the surface of the user's body, and by forming the first curved surface 21aC, the first curved surface 21aC feels comfortable against the user's skin and provides a comfortable wearing experience even when used for long periods of time.

[0051] Furthermore, the light incontinence pad 1 of this embodiment is characterized in that the pad body 10 is a member that is arranged so as to be able to cross the covering portion 12 along the short direction of the light incontinence pad 1 in a plan view, and has a band portion 30 that is composed of a right band 31a and a left band 31b that can be detached.

[0052] As a result, the right band 31a and the left band 31b can be connected to surround the crotch portion of the underwear, and the band portion 30 can be fixed at a desired position on the underwear, allowing the light incontinence pad 1 to be attached to the underwear.

[0053] Furthermore, light incontinence pad 1 of this embodiment is characterized in that the fabric material of contact portion 11 of pad body 10 is a cotton material.

[0054] This increases the absorbency of the contact portion 11 and improves the comfort when it comes into contact with the body surface of the user, making it possible to obtain a light incontinence pad that is suitable for long-term use.

[0055] Here, joining the sealing part 20 to the pad body 10 by four-fold piping stitching has the following advantages in relation to using cotton as the fabric material for the contact part 11. That is, while using cotton as the fabric material for the contact part 11 provides the above-mentioned effects, it is inferior to other materials such as synthetic fibers in terms of heat resistance and chemical resistance, and therefore welding, crimping, adhesives, or other means cannot be used to fix the sealing part 20, and sewing is the only option.

[0056] Therefore, as described above, by joining the sealing portion 20 by four-fold piping stitching, it is possible to achieve both leakproofness of the pad body 10 and a comfortable feeling when it comes into contact with the body surface.

[0057] In addition to the above configuration, the light incontinence pad 1 of this embodiment may be configured to include an anti-slip member 50 on the surface of the covering portion 12 of the pad main body 10, as shown in Fig. 8. The anti-slip member 50 is made of a material such as silicone rubber, and has an outer shape and outer dimensions that allow it to be positioned at least inside the sealing portion 20, and a thickness of approximately several tens of micrometers to less than several millimeters, and is fixed to the pad main body 10 by means of adhesion, bonding, or the like.

[0058] By providing the light incontinence pad 1 with the anti-slip member 50, when the pad is in use, the anti-slip member 50 comes into close contact between the underwear and the pad body 10, preventing misalignment between the underwear and the light incontinence pad 1. As a result, the light incontinence pad 1 can be stably fixed in the desired position on the user's body surface.

[0059] As described above, the light incontinence pad 1 according to the embodiment of the present invention can be reused and has excellent leak-proofing properties.

[0060] However, the present invention is not limited to the above-described embodiments.

[0061] In the above description, the pad body 10 has a laminated structure of the contact portion 11, the absorbent portion 13, and the covering portion 12. However, the pad body of the present invention may have at least a contact portion formed of a fabric material. Therefore, the pad body 10 may have a four or more layer structure, or a two-layer structure. For example, the pad body 10 may have a single functional layer that combines the functions of the absorbent portion 13 and the covering portion 12, independent of the contact portion 11.

[0062] In the above description, the pad body 10 is sealed by the sealing portion 20 using four-fold piping. However, the sealing portion of the present invention may be provided so as to seamlessly cover the periphery of the pad body. Therefore, the pad body 10 may be sealed using other sewing techniques, or by bonding using pressure bonding, welding, adhesives, or the like. However, if the contact portion 11 is made of cotton, sewing using four-fold piping is most preferable.

[0063] Furthermore, in the above description, the sealing portion 20 has the first edge portion 21a having the first curved surface 21aC and the second edge portion 21b having the second curved surface 21bC, but the second curved surface 21bC in the second edge portion 21b may be omitted.

[0064] In the above description, the first edge 21a has a first double portion 21aT where the band body 21 overlaps twice, and the second edge 21b has a second double portion 21bT where the band body 21 overlaps twice, but the overlap between each of the first edge 21a and the second edge 21b and the band body 21 may be three or more times. The number of overlaps may differ between the first edge 21a and the second edge 21b.

[0065] Furthermore, in the above description, the sealing of the pad body 10 by the sealing portion 20 is performed by sewing with piping, but as shown in Fig. 9, the surfaces of the first edge portion 21a and the second edge portion 21b, which are sewn together with the suture thread 40, may be further covered with a seal 41 made of synthetic rubber such as silicone rubber or urethane rubber so as to cover the entire suture thread 40. This makes it possible to more reliably prevent liquid from leaking from the sewn portion.

[0066] In the above description, the contact portion 11 of the pad body 10 is composed of the central portion 11a, the left portion 11b, and the right portion 11c, each of which is an independent base cloth. However, the contact portion of the present invention only needs to have a folded end with a fold at each end along the short side, which is directed toward the center. Therefore, the central portion 11a, the left portion 11b, and the right portion 11c may be composed of a single piece of base cloth or multiple layers of base cloth folded back.

[0067] In the above description, the pad body 10 has an oval outer shape in a plan view, but the pad body of the present invention may have any shape as long as it extends in the longitudinal direction and in a lateral direction generally perpendicular to the longitudinal direction in a plan view. As an example, Fig. 10 shows a light incontinence pad 2 in which the pad body 10 has a generally cocoon-shaped shape in a plan view. Alternatively, the pad body of the present invention may have any of the outer shapes of a rectangle, a polygon, or a generally ellipse.

[0068] Furthermore, in the above description, the present invention is described as being suitable for light incontinence pads, such as light incontinence pad 1 or light incontinence pad 2, but the present invention is not limited to any other uses or configurations as long as it is an absorbent pad. Therefore, the present invention may be embodied as any absorbent pad intended to absorb bodily secretions, such as sanitary napkins, panty liners, baby diapers, nursing diapers, underarm sweat pads, and the like.

[0069] In short, the present invention may be implemented by making various modifications to the above-described embodiments, including those described above, without departing from the spirit of the present invention and within the same technical scope. [Industrial Applicability]

[0070] The present invention as described above can be used repeatedly and has excellent leak prevention properties at the end faces and periphery, and is particularly useful as a pad for light incontinence. [Explanation of symbols]
