Abstract
Description
Detailed Description of the Invention [Technical field]
[0001] The present invention relates to a cloth absorbent pad that can deal with urinary incontinence and can be easily attached to and detached from men's underwear. [Background technology]
[0002] Conventionally, most absorbent pads have been attached to the inside of men's underwear worn on the lower body with adhesive tape, or have absorbent material sewn to the underwear, or have hook-and-loop tape sewn or fused to the inside of the underwear and hook-and-loop tape sewn or fused to the surface of the absorbent pad. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent 7001860 Summary of the Invention [Problem to be solved by the invention]
[0004] Many conventional absorbent pads are flat products, which makes it easy for the penis to move, and urine may leak outside the absorbent pad when it leaks. When used, it is attached to the inside of the underwear with adhesive tape, but when reattaching, the adhesive tape may stick to an unintended place, making the absorbent pad itself unusable. Many conventional absorbent pads are disposable products, and disposal has a negative impact on the environment. Products that have an absorbent pad sewn to the underwear body require changing because of the ammonia smell that comes from absorbed urine. In addition, products that allow the absorbent pad to be removed by sewing or fusing hook-and-loop tape to the inside of the underwear and sewing or fusing hook-and-loop tape to the outside of the absorbent pad have the problem that they cannot be used in any combination other than the one in question. Furthermore, conventional absorbent pads need to be in close contact with the skin, and are limited to use with underwear that is relatively close to the skin, such as briefs and boxer shorts.
[0005] To solve the above problems, the present invention aims to provide a urine absorption pad body that can deal with urine leakage, is not limited to a specific pair of pants, and can be easily attached and detached even when the pants are worn. [Means for solving the problem]
[0006] In order to achieve the above object, this invention is a pad that has one or more darts inserted within the lower 1 / 3 of the central three-dimensional part to create a three-dimensional space that allows the penis and scrotum to be grasped, and left and right flat parts that cover the penis when it comes out of the central three-dimensional part, thereby preventing urine leakage from leaving the pad.
[0007] One or more magnetic materials are sewn or attached to a position within the upper 1 / 3 of the pad, and the pad is used inside men's underwear, and the underwear is held from the outside by using the magnetic material sewn or attached to the urine absorption pad holding belt, so that the pad can be held in any appropriate position.
[0008] When the center of the central three-dimensional part 2 of the urine absorption pad main body 1 is vertical, the horizontal angle from the lowest point to the end point of the lower part of the central three-dimensional part 2 is set within +10 degrees to -30 degrees, so that the scrotum 14 is less likely to come off the bottom surface of the central three-dimensional part 2. With this structure, the lower part of the central three-dimensional part 2 serves as a fulcrum, and the magnetic material 5 sewn or attached to the pad main body is fixed from the outside of the underwear with the magnetic material 5 sewn or attached to the urine absorption pad holding belt 6. By stretching the urine absorption pad main body 1 between the part that grips the scrotum 14 and the magnetic material, the pad is less likely to come off, and it is not limited to the use of underwear that has a high degree of adhesion to the body, such as pre-sleeves and boxer shorts, but can also be used with trunks that have a low degree of adhesion to the body.
[0009] In addition, while incontinence pads made of nonwoven fabric with adhesive tape must be disposed of after use, this pad is made of cloth and uses a magnetic material to enable it to be attached and detached, so it can be washed and reused. Effect of the Invention
[0010] This invention is constructed as described above, and by changing the shape of the lower part of central three-dimensional section 2 and sewing or adhering magnetic material 5 to the upper part of the pad, and by clamping men's underwear 12 with magnetic material 5 sewn or adhered to urine absorbent pad holding belt 6 from the outside of men's underwear 12, it can be used not only with briefs or boxer shorts but also with trunks, and since it is made of cloth, it can be washed and used repeatedly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] One embodiment of the present invention is shown in Figs. 1 and 2. In this embodiment, the penis 13 and scrotum 14 are placed in appropriate positions on the lower back surface of the central three-dimensional portion 2 of the urine absorbent pad main body 1, and magnetic material 5 is sewn or attached to each of the urine absorbent pad main body 1 and the urine absorbent pad holding belt 6, and used as a pair.
[0013] The urine absorbent pad body 1 is made up of four layers, a surface cloth 8, a water-absorbent cloth 9, a waterproof cloth 10, and a back cloth (cloth facing the skin) 11, as shown in Fig. 3(d). The fabric composition of each of these cloths 8, 9, 10, and 11 is not limited, and may be appropriately selected according to the application. For example, the waterproof cloth 10 may be made to have waterproof properties, the water-absorbent cloth 9 may be made to have water-absorbency properties, and the back cloth 11 may be made to have quick-drying properties (the property of not allowing water to return to its original state after it has passed through it).
[0014] At least one dart 4 is formed in a curved shape at the bottom of the central part 2 of the urine absorbent pad, and darts 4 are also formed in the same positions in the outer fabric 8, absorbent fabric 9, waterproof fabric 10 and lining fabric (skin side fabric) 11, which are then overlapped to form a space shape that can accommodate a male penis 13 and scrotum 14.
[0015] At least one magnetic body 5 is sewn or stuck to the upper part of the surface of the urine absorption pad body 1, and the male underwear 12 can be held by the magnetic body 5 sewn or stuck to the urine absorption pad holding belt 6.
[0016] The left and right flat parts 3 of the outer fabric 8, water-absorbent fabric 9, waterproof fabric 10, and lining fabric (cloth facing the skin) 11 are sewn or fused to the central three-dimensional part 2. After sewing, waterproof tape is fused to the waterproof fabric 10 to prevent leakage to the surface from the sewn parts.
[0017] When there are multiple magnetic bodies 5 sewn or attached to the urine absorbent pad holding belt 6, the positions are the same as the positions of the magnetic bodies 5 sewn or attached to the urine absorbent pad main body 1. This is not the case when there is only one magnetic body 5. [Explanation of symbols]
