Description

Technical Field

[0001] The utility model relates to the technical field of underwear, in particular to a pair of water-absorbing and urine-leakage-proof underwear. Background Art

[0002] There are many styles of adult disposable diapers on the market. However, disposable diapers are not breathable, are not comfortable, and are thrown away after use. They are expensive to use and are also wasteful for people with mild incontinence.

[0003] In order to improve wearing comfort, avoid stuffiness and reduce usage costs, there are currently many styles of non-disposable water-absorbing and leak-proof underwear on the market. In order to prevent side leakage, the previous water-absorbing and leak-proof underwear mainly focused on how to improve the water absorption performance of the crotch of the underwear. Therefore, the crotch fabric is made thicker and thicker, or high-tech materials with good water absorption performance are used in the crotch. However, the focus on the water absorption of the crotch material is often ignored. The rationality of its structure is often ignored. The crotch fabric is too thick, which will make the crotch bloated and reduce wearing comfort. At the same time, the width of the absorbent pad extends to the edge of the crotch. The thicker edge is easy to rub the legs. Moreover, although it seems to increase the water absorption area of ​​the absorbent pad, in fact, the absorbent pad also has the function of guiding water. The liquid will also seep out along with the absorbent pad, resulting in urine leakage. Utility Model Content

[0004] The utility model aims to provide a water-absorbing and urine-leakage-proof underwear. A water-absorbing pad is provided at the crotch of the underwear body. Anti-leakage grooves are provided around the water-absorbing pad to separate the water-absorbing pad from the edge of the crotch to prevent liquid leakage. A specially shaped water guide groove is provided on the water-absorbing pad to guide the liquid to the surrounding areas of the water-absorbing pad, so that the pad absorbs the liquid more evenly and improves wearing comfort.

[0005] The utility model comprises an underpants main body, which comprises a front piece and a back piece, the lower edges of which are sewn together by a crotch portion; left and right leg openings are provided on the underpants main body, and the utility model is characterized in that a leak-proof component is provided at the crotch portion, which comprises an absorbent pad, an outer edge of which is provided with a leak-proof groove, a buffer cloth is covered above the leak-proof groove, one side of the buffer cloth is sewn to the outer edge of the absorbent pad, and the other side of the buffer cloth is sewn to the outer edge of the leak-proof groove, thereby forming a flat leak-proof cavity between the bottom of the buffer cloth and the leak-proof groove.

[0006] Preferably, there are at least two leakage-proof grooves, which are distributed on the left and right sides of the absorbent pad.

[0007] Preferably, there are four leakage-proof grooves distributed around the absorbent pad.

[0008] Preferably, the edges of the leg openings are wrapped with elastic binding.

[0009] Preferably, the absorbent pad is formed by stacking and sewing a plurality of layers of absorbent material in sequence, and the outermost layer is a mesh skin-friendly material.

[0010] Preferably, the absorbent pad is provided with a water guide groove, which includes a main water guide groove and a water guide groove. The main water guide groove is arranged in the middle of the absorbent pad and extends along the length direction of the absorbent pad; a water guide groove is provided on the outside of the main water guide groove, and the water guide groove extends outward along the four sides of the absorbent pad.

[0011] Preferably, there are at least two main water guide grooves, which are symmetrically arranged in a "human" shape on both sides of the longitudinal center line of the water absorbent pad with the longitudinal center line of the water absorbent pad as the center.

[0012] Preferably, the width of the main water guide groove decreases from the front side to the rear side of the water absorbent pad.

[0013] Preferably, the water guide grooves are in an "I" shape, and the number of the water guide grooves is not less than four. The water guide grooves start from the main water guide groove and are arranged divergently to the surrounding areas with the center of the water absorbent pad as the center.

[0014] Preferably, the side walls of the main water guide groove and the water guide groove are provided with elastic strips.

[0015] In summary, the present invention has the following beneficial effects:

[0016] 1. The size of the absorbent pad is slightly smaller than the size of the crotch. The outer edge of the absorbent pad is provided with a leak-proof groove, and a buffer cloth is sewn above the leak-proof groove, so that a flat leak-proof cavity is formed between the bottom of the buffer cloth and the leak-proof groove; the absorbent pad is separated from the edge of the crotch to prevent liquid on the absorbent pad from seeping along the absorbent pad to the crotch edge, thereby causing urine leakage; at the same time, the leak-proof groove and the leak-proof cavity act as a buffer for the liquid on the absorbent pad, which can further prevent urine leakage; in addition, the buffer cloth and the leak-proof cavity form a transition between the thicker absorbent pad and the thinner crotch, making it softer to wear; finally, when the absorbent pad absorbs a certain amount of liquid, the liquid-filled absorbent pad will expand to a certain extent, and the leak-proof cavity can effectively buffer the volume change caused by this expansion;

[0017] 2. The edges of the leg openings are wrapped with elastic edging. The elastic edging is made of elastic material, with one end sewn to the inner surface of the leg opening and the other end sewn to the inner surface of the leg opening, thus wrapping the edge of the leg opening. The elastic edging makes the leg opening more elastic and airtight, and can fit the legs of people with different leg thicknesses to prevent urine leakage at the leg openings. At the same time, the elastic edging wraps the edge of the leg openings, making it softer and preventing it from rubbing the legs.

[0018] 3. The absorbent pad is provided with a water guide groove. The main water guide groove quickly drains the liquid in the center of the absorbent pad where the liquid volume is larger to the front and back ends of the absorbent pad, preventing the liquid from accumulating in the middle of the absorbent pad and quickly filling up, causing discomfort to wear or even urine leakage; the main water guide groove is in the shape of a "human", which cooperates with the structure of the human buttocks, making the absorbent pad fit the human buttocks more closely and making body movements more comfortable; the water guide groove further drains the liquid in the center of the absorbent pad and the main water guide groove evenly to the surrounding areas of the absorbent pad, so that the absorbent pad can absorb water evenly and fully, preventing uneven water absorption, which may lead to local drying or local soaking.

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] The orientations mentioned in this specification are based on the orientations of the water-absorbing and urine-leakage-proof underwear of the present invention during normal operation, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0028] like Figures 1 to 4As shown together, a water-absorbing and urine-leakage-proof underwear includes an underwear main body 1, and the underwear main body 1 includes a front piece 2 and a back piece 3. The lower edges of the front piece 2 and the back piece 3 are sewn together by a crotch portion 4, and the width of the crotch portion 4 is set to a structural form in which the front portion is narrow and the back portion gradually widens; two left and right leg openings 5 ​​are set on the underwear main body 1, and the crotch portion 4 is located between the two leg openings 5; the crotch portion 4 is provided with an anti-leakage component 6, and the anti-leakage component 6 includes a water-absorbing pad 601, which is fixed to the inner side of the crotch portion 4, and the water-absorbing pad 601 is formed into a shape that is roughly the same as or similar to the crotch portion 4, and its size is slightly smaller than the size of the crotch 4.

[0029] The outer edge of the absorbent pad 601 is provided with a leak-proof groove 602, and the top of the leak-proof groove 602 is covered with a buffer cloth 603. One side of the buffer cloth 603 is sewn to the outer edge of the absorbent pad 601, and the other side of the buffer cloth 603 is sewn to the outer edge of the leak-proof groove 602, wherein the outer edge of the absorbent pad 601 extends to the bottom of the buffer cloth 603, and the sewing surface between the absorbent pad 601 and the buffer cloth 603 is located at the upper part of the absorbent pad 601.

[0030] The underwear main body 1 and the buffer cloth 603 are made of skin-friendly cotton materials such as cotton, nylon and polyester. The two can be made of the same material or different materials.

[0031] The thickness of the buffer cloth 603 is relatively thin, and its thickness is equivalent to that of the underwear main body 1; the water-absorbing pad 601 is made of a multi-layer structure of water-absorbing materials stacked and sewn in sequence, and its outermost layer is a mesh skin-friendly material, which makes it more breathable. As a result, a certain thickness difference is formed between the water-absorbing pad 601 and the crotch 4, so that a flat leak-proof cavity 604 is formed between the bottom of the buffer cloth 603 and the leak-proof groove 602; the width of the buffer cloth 603 is greater than the width of the leak-proof groove 602, which means that when the buffer cloth 603 is sewn above the leak-proof groove 602, the buffer cloth 603 needs to be bent to a certain extent in the width direction to form the leak-proof cavity 604 as described above.

[0032] The size of the absorbent pad 601 is slightly smaller than that of the crotch 4. A leak-proof groove 602 is provided on the outer edge of the absorbent pad 601 to separate the absorbent pad 601 from the edge of the crotch 4, preventing liquid on the absorbent pad 601 from seeping along the absorbent pad 601 to the edge of the crotch 4, thereby preventing urine leakage. At the same time, the leak-proof groove 602 and the leak-proof cavity 604 act as a buffer for the liquid on the absorbent pad 601, which can further prevent urine leakage. In addition, the buffer cloth 603 and the leak-proof cavity 604 form a transition between the thicker absorbent pad 601 and the thinner crotch 4, making it softer to wear. Finally, when the absorbent pad 601 absorbs a certain amount of liquid, the absorbent pad 601 filled with liquid will expand to a certain extent, and the leak-proof cavity 604 can well buffer the volume change caused by this expansion.

[0033] In one embodiment, there are at least two leakage-proof grooves 602 , which are distributed on the left and right sides of the absorbent pad 601 .

[0034] In another embodiment, four leakage-proof grooves 602 are provided and distributed around the absorbent pad 601 .

[0035] Furthermore, the edge of the leg opening 5 is wrapped with an elastic edging 605, which is made of elastic material, one end of which is sewn to the inner surface of the leg opening 5, and the other end is sewn to the inner surface of the leg opening 5, thereby wrapping the edge of the leg opening 5; the elastic edging 605 makes the leg opening 5 more elastic and sealed, and can fit the legs of people with different leg thicknesses to prevent urine leakage at the leg opening 5; at the same time, the elastic edging 605 wraps the edge of the leg opening 5, making the area softer and preventing it from rubbing the legs.

[0036] like Figure 5 and Figure 6 As shown, the absorbent pad 601 is provided with a water guide groove, which includes a main water guide groove 606 and a water guide groove 607. The main water guide groove 606 is arranged in the middle of the absorbent pad 601 and extends along the length direction of the absorbent pad 601; the outer side of the main water guide groove 606 is provided with a water guide groove 607, and the water guide groove 607 extends outward along the four sides of the absorbent pad 601.

[0037] There are no less than two main water guide grooves 606, which are symmetrically arranged in a "human" shape on both sides of the longitudinal center line of the absorbent pad 601 with the longitudinal center line of the absorbent pad 601 as the center; the main water guide grooves 606 quickly drain the liquid in the center position of the absorbent pad 601 with a larger amount of liquid to the front and back ends of the absorbent pad 601, preventing the liquid from accumulating in the middle part of the absorbent pad 601 and quickly becoming full, causing discomfort when wearing or even urine leakage; the main water guide grooves 606 are in a "human" shape, which cooperates with the structure of the human buttocks, so that the absorbent pad 601 fits the human buttocks better and the body moves more freely; the width of the main water guide grooves 606 decreases from the front side to the back side of the absorbent pad 601, so that more liquid can be drained toward the back of the absorbent pad 601 with a larger water absorption area.

[0038] The water guide grooves 607 are in the shape of an "I", and the number of the water guide grooves 607 is not less than four. The water guide grooves 607 start from the main water guide groove 606, and are arranged divergently to the surrounding areas with the center of the absorbent pad 601 as the center, further draining the liquid at the center of the absorbent pad 601 and the main water guide groove 606 evenly to the surrounding areas of the absorbent pad 601, so that the absorbent pad 601 can absorb water evenly and fully, preventing uneven water absorption, resulting in local drying and local soaking.

[0039] The side walls of the main water guide groove 606 and the water guide groove 607 are provided with elastic strips 608. This structure is conducive to water conduction and can also enable the absorbent pad 601 to follow the crotch 4 and have a certain degree of extensibility in the front-back and left-right directions, thereby increasing the elasticity of the underwear and enhancing the wearing comfort; at the same time, it can also prevent the absorbent pad 601 from being stretched when the crotch 4 of the underwear is stretched, resulting in its size being unable to completely cover the crotch 4, thereby causing urine leakage.

[0040] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
