Abstract
Description
Technical Field
[0001] This utility model relates to the field of underwear technology, specifically to a seamless triangle underwear for women that prevents buttock pinching. Background Technology
[0002] Women's underwear is a type of close-fitting lower body underwear. As a necessity in life, the comfort and health of wearing it are increasingly becoming the focus of women's attention.
[0003] Currently, when the leg openings of women's seamless underwear are completely bare, the crotch is directly attached to the lining. The crotch area is prone to deformation after washing. As the crotch area becomes narrower and longer, it is easy to cause problems such as the crotch getting stuck and the buttocks being pinched. In addition, the crotch being too narrow is unhygienic. Therefore, the inventor has invented a seamless triangle panty for women that prevents buttock pinching to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a seamless triangle panty for women that prevents buttock pinching. It effectively solves the problems of the crotch area easily deforming after washing, and the problem of the crotch area becoming narrower and longer, which can easily cause the crotch to get stuck and pinch the buttocks. In addition, the problem of the bottom being too narrow is unhygienic.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a women's anti-pinch seamless triangle panty, comprising: a front piece, a back piece, and a crotch piece fixed together, wherein a shaping sticker is pasted on the inner and / or outer edges of the crotch piece, and the shaping sticker is bent and pasted on the inner lower and / or outer lower edge of the back piece.
[0006] Optionally, the shaping adhesive is a TPU film.
[0007] Optionally, the rear panel may include a hip area.
[0008] Optionally, the end of the shaping patch is located at the inner lower middle edge and / or the outer lower middle edge of the back piece.
[0009] Optionally, the underwear body is made of elastic fabric.
[0010] Optionally, the front piece, back piece, and crotch are integrally molded, with the back piece extending to the front waistband of the underwear and being glued to the front piece.
[0011] Optionally, the rear panel and the lower end of the crotch are arc-shaped.
[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. When the user wears these underwear, the leg openings will be stretched. According to the principle of force distribution, the fabric parts without shaping patches will be stretched first, thereby reducing the stretching of the crotch and ensuring that the sides of the crotch have a certain degree of elasticity, stabilizing the shape of the crotch. This can reduce the sides of the crotch from slipping towards the middle when wearing, avoiding crotch entrapment and hygiene problems caused by a too narrow crotch.
[0013] 2. Because the shaping patch on the crotch extends to the inner lower side and / or outer lower edge of the back panel (i.e., the back of the leg opening) to a certain length, it can cover the key parts of the bottom of the buttocks, realize local force distribution on the bottom of the buttocks, and have a certain support. When combined with the molding of the back buttock area of the underwear, it can create a "smiling buttock" effect, that is, the back panel and the lower end of the crotch are arc-shaped, while stabilizing the back of the leg opening, reducing the back of the leg opening from riding up, and improving the problem of buttock clamping.
[0014] 3. The shaping adhesive is applied to the crotch and back of the underwear, in a concealed position, while maintaining the seamless effect of seamless underwear. This localized application of pressure addresses the common problem of seamless underwear pinching the buttocks. Attached Figure Description
[0015] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0016] Figure 1 This is a schematic diagram of the overall main structure of this utility model; Figure 2 This is an unfolded view of the front piece, rear piece, and crotch of this utility model.
[0017] Explanation of the attached labels: Front piece 1, Ventilation hole 11, Breathable mesh 12, Lining fabric 13, Back piece 2, Shaping patch 21, Hip area 22, Crotch 3. Detailed Implementation
[0018] The present invention will be further described in detail below with reference to the accompanying drawings.
[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
[0020] This embodiment relates to a seamless, anti-pinch triangle panty for women, such as... Figure 1-2As shown, the panties include a front piece 1, a back piece 2, and a crotch 3 that are fixed together. A shaping sticker 21 is pasted on the inner and / or outer edges of the crotch 3. The shaping sticker 21 is bent and pasted on the inner lower edge and / or outer lower edge of the back piece 2. The women's anti-pinch seamless triangle panties are made of elastic fabric.
[0021] When the user wears the underwear, the leg openings (not shown) will be stretched. According to the principle of force, the fabric parts without the shaping patch 21 will be stretched first, thereby reducing the stretching of the crotch 3 and ensuring that the sides of the crotch 3 have a certain degree of elasticity, stabilizing the shape of the crotch 3. This can reduce the sides of the crotch 3 from slipping towards the middle when wearing, avoiding the problem of the crotch getting stuck and the problem of the crotch 3 being too narrow, which would lead to unhygienic issues.
[0022] Because the shaping patch 21 on the crotch 3 extends to the inner lower side and / or outer lower edge of the back piece 2 (i.e., the back of the foot opening) for a certain length, it can cover the key parts of the bottom of the buttocks, realize local force distribution on the bottom of the buttocks, and have a certain support force. When combined with the molding of the back buttock area of the underwear in the later stage, it can create a "smiling buttock" effect, that is, the lower end of the back piece 2 and the crotch 3 are arc-shaped, while stabilizing the back of the foot opening, reducing the upward movement of the back of the foot opening, and improving the problem of buttock clamping.
[0023] The shaping patch 21 is positioned on both sides of the crotch 3 to the bottom of the buttocks of the underwear. The position is relatively hidden, and the seamless effect of the seamless underwear is maintained in appearance. The localized process solves the problem of seamless underwear easily pinching the buttocks.
[0024] Furthermore, the shaping patch 21 is preferably a TPU film. The TPU film is thin, skin-friendly, and elastic, and can deform elastically along with the underwear without affecting the wearing experience. It should be noted that the elasticity of the TPU film is less than that of the underwear, and it can effectively shape the leg openings and crotch of the underwear.
[0025] Furthermore, the end of the shaping patch 21 is located at the inner lower middle edge and / or outer lower middle edge of the back piece 2, which can support the bottom of the human buttocks.
[0026] like Figure 2 As shown, the back piece 2 has a buttock area 22, which is processed by a molding process to fit the human buttocks.
[0027] Specifically, such as Figure 1-2 As shown, the front piece 1, back piece 2, and crotch 3 are integrally molded. The back piece 2 extends to the front waistband of the underwear and is glued to the front piece 1. This design makes the underwear more comfortable to wear. The seam between the back piece 2 and the front piece 1 is not located on the sides of the waist, which can prevent dents from appearing when the user wears the underwear.
[0028] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
