Description

Technical Field

[0001] This utility model relates to the field of underwear technology, specifically a new type of underwear with anti-leakage function. Background Technology

[0002] Underwear is a type of underwear worn close to the body. Men's and women's underwear are different due to differences in physiological structure. Originally used to cover the body and protect the private parts, underwear now also incorporates aesthetic designs. It can be divided into different styles such as briefs, boxer briefs, thongs, and maternity underwear based on its shape.

[0003] Current regular underwear lacks specific leak-proof design, making it prone to leakage for people with urinary incontinence. This leads to damp clothing, skin discomfort, and social embarrassment. Some leak-proof products use a single waterproof layer, which suffers from poor breathability, insufficient fit, and reduced leak-proof effect during activity. Furthermore, they do not adequately consider optimized urine storage space, failing to meet the comfort and functionality requirements for daily wear. Therefore, there is an urgent need for a new type of leak-proof underwear that combines leak prevention, breathability, comfort, and reasonable urine storage.

[0004] Now, a new type of underwear with anti-leakage function is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a new type of underwear with anti-leakage function to solve the problem of poor anti-leakage effect mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel pair of underwear with anti-leakage function, comprising a front piece, a back piece sewn between the back sides of both sides of the front piece, a leg opening one sewn between the lower left corner of the front piece and the back piece, a leg opening two sewn between the lower right corner of the front piece and the back piece, a crotch piece provided at the center of the front of the leg opening one and the leg opening two, and the crotch piece including a urine-conducting layer one, a urine-storing layer one provided outside the urine-conducting layer one, and an anti-leakage layer one provided outside the urine-storing layer one, a lower waistband sewn at the top between the front piece and the back piece, and an elastic band fixed to the top of the lower waistband, and an upper waistband sewn around the top of the elastic band.

[0007] As a further technical solution of this utility model, the first catheter layer, the first urine storage layer, and the first leak-proof layer have the same area, and the first urine storage layer is attached between the first catheter layer and the first leak-proof layer.

[0008] As a further technical solution of this utility model, a buttock-covering piece is provided at the center of the rear between the first and second trouser legs, and the buttock-covering piece includes a second urinary catheter layer, a second urine storage layer is provided outside the second urinary catheter layer, and a second leak-proof layer is provided outside the second urine storage layer.

[0009] As a further technical solution of this utility model, the second catheter layer, the second urine storage layer, and the second leak-proof layer have the same area, and the second urine storage layer is attached between the second catheter layer and the second leak-proof layer.

[0010] As a further technical solution of this utility model, elastic leak-proof edges are sewn around the bottom edges of both the first and second trouser legs, and a silicone strip is fixed inside the elastic leak-proof edges.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the new type of underwear with anti-leakage function not only prevents urine from seeping into the underwear and achieves close-fitting underwear, but also allows for adjustment of the waistband length;

[0012] (1) A crotch piece is provided at the center of the front between the first and second leg openings, and a hip-covering piece is provided at the center of the back between the first and second leg openings. The crotch piece and the hip-covering piece are connected to each other. The crotch piece is divided into a urine-conducting layer 1, a urine-storing layer 1, and a leak-proof layer 1 from the inside out. The hip-covering piece is divided into a urine-conducting layer 2, a urine-storing layer 2, and a leak-proof layer 2 from the inside out. Both the urine-conducting layer 1 and the urine-conducting layer 2 are made of skin-friendly and hydrophobic materials to guide urine to quickly penetrate into the urine-storing layer 1 and the urine-storing layer 2. The urine-storing layer 1 and the urine-storing layer 2 are made of highly absorbent resin SAP cotton cores. The urine-storing layer 1 has a large pouch urine-storing structure to increase the urine-storing space and adapt to different urine volume needs. Both the leak-proof layer 1 and the leak-proof layer 2 are made of TPU breathable film. The edges are sewn to the underwear body to form an effective leak-proof barrier, improve wearing comfort and urine-conducting efficiency, and avoid urine retention and skin irritation. It is suitable for daily wear and care scenarios for people with urinary incontinence.

[0013] (2) By sewing elastic leak-proof edges around the bottom edges of the first and second pant legs, and sewing elastic leak-proof edges at the bottom of the first and second pant legs, the fit of the underwear to the body can be enhanced, adapting to different activity states such as walking, sitting and lying down. The inside of the elastic leak-proof edge is fitted with a silicone strip to prevent side leakage during activity. The waistband is designed with a wide elastic band with an elasticity value of -N, ensuring a secure fit without marks and adapting to human activity.

[0014] (3) By sewing a waistband at the top between the front and back pieces, when wearing this underwear, the legs are respectively inserted into the first and second legs of the pant leg. Pinch the top waistband and pull the elastic band between the waistband and the upper waistband. After adjusting the distance between the waistband and the upper waistband, the waistband, elastic band and upper waistband all wrap around the waist of the body. The height of the waistband can be adjusted according to the comfort of wearing. There is friction between the waistband and the skin, and it will not easily bounce back automatically.
