Description

Technical Field

[0001] This utility model relates to the field of underwear technology, and in particular to a reversible underwear with anti-friction cups. Background Technology

[0002] Traditional underwear often causes discomfort such as redness and itching due to repeated friction between the fabric and the skin during wear, especially during exercise or prolonged wear. To alleviate this problem, existing technologies often reduce friction by adding cushioning layers (such as sponge pads). However, sponge materials have significant drawbacks: their low porosity allows sweat to accumulate easily, creating conditions for bacterial growth (low antibacterial rate); furthermore, sponges are prone to deformation after repeated washing, retaining less than 50% of their elasticity, leading to a rapid loss of support and affecting the wearing experience.

[0003] Furthermore, as users' demand for diverse functions in underwear increases, reversible underwear is gradually becoming a market trend. However, most existing reversible underwear achieves this by simply flipping it over, but the fabric material, feel, or visual effect of the two sides are often inconsistent (e.g., one side is a smooth fabric, and the other side is a rough mesh), resulting in differences in support, comfort, or aesthetics when worn on both sides, failing to meet users' dual needs for function and appearance.

[0004] Therefore, a technical solution to the above problems is needed. Utility Model Content

[0005] In order to solve the technical problems existing in the prior art, the purpose of this utility model is to provide a reversible bra with anti-friction cups to solve the above-mentioned technical problems.

[0006] To achieve its purpose, the present invention adopts the following technical solution:

[0007] A reversible bra with anti-friction cups, including cups, the cups comprising a first layer and a second layer connected to each other, the first layer and the second layer being stacked and connected, and forming a cavity between the two;

[0008] Both the first and second layers are made of highly elastic fiber fabric. When in use, the cup can be flipped between the first and second layers, allowing the cup to switch between having the first layer on the outer layer and having the second layer on the outer layer.

[0009] In some embodiments, the maximum thickness of the cavity portion does not exceed 1 cm.

[0010] In some implementations, the area of ​​the cavity is smaller than the solid area of ​​other areas of the cup.

[0011] In some embodiments, the cavity is located at the center of the cup, and the cavity is a hollow structure of one of the following: circular, crescent-shaped, or star-shaped.

[0012] In some implementations, the first layer and the second layer have different colors and / or surface textures on their outward-facing sides.

[0013] In some embodiments, a wearing part for wearing is also included, the wearing part including a front flap, a back flap and shoulder straps, the cups being mounted on the front flap.

[0014] In some embodiments, a wearable part for wearing is also included, the wearable part including elastic side wings located on both sides of the cup, the wearable part and the cup forming a strapless annular closed structure.

[0015] In some embodiments, both the first layer and the second layer are made of the same highly elastic fiber fabric.

[0016] The anti-friction bra cup of this utility model is a reversible bra with a cavity inside the cup aligned with the nipple. The 1.0cm buffer space reduces the contact pressure and effectively reduces skin friction damage. It is especially suitable for high-friction scenarios such as sports and long-term wear, and avoids skin problems such as redness and itching caused by repeated friction between the cup material and the nipple.

[0017] The anti-friction bra cup of this utility model is a reversible bra that uses a high-elasticity fiber woven fabric (such as warp-knitted mesh, elastic composite fiber) to replace the traditional sponge, which solves the problems of poor breathability, easy growth of bacteria, and rapid loss of elasticity of traditional bra cup sponge materials.

[0018] The anti-friction bra cup of this utility model is a reversible bra. The first and second layers are made of the same medical-grade high-elastic fiber to ensure that there is no difference in touch, support and breathability on both sides. In addition, the two sides are dyed with different dyeing processes to achieve independent visual identification and meet the user's dual needs for function and aesthetics.

[0029] like Figures 1 to 3 As shown, a reversible bra with anti-friction cups includes two symmetrical cups 100 and a wearing part 200 connecting the two cups 100. The wearing part 200 is worn on the user so that the cups 100 support and cover the breasts and breast skin. The cups 100 are provided with a cavity 130, which can reduce friction when worn and avoid skin discomfort caused by repeated friction of materials during exercise or daily activities.

[0030] Among them, see Figure 1 and Figure 2 The hollow portion 130 is disposed between the inner layer 110 (first layer) and the outer layer 120 (second layer) of the bra cup 100. When the bra cup 100 is worn through the wearing part 200, the hollow portion 130 corresponds to the nipple position of the breast. The position of the hollow portion 130 can be deformed by compression to reduce friction. Specifically, in this embodiment, each bra cup 100 is composed of only two layers of fabric, which are connected to each other to form an internally hollow cavity 130. During use, the hollow cavity 130 can reduce friction when worn.

[0031] Preferably, the maximum thickness of the cavity 130 in the cup 100 does not exceed 1 cm. This size allows the cup 100 to provide sufficient cushioning space at the position of the cavity 130, while avoiding insufficient support due to an excessively large cavity. When worn, the cavity 13013 is deformed by compression, dispersing the contact pressure originally concentrated on the nipple and surrounding skin to the surrounding area, effectively reducing skin discomfort such as redness and itching caused by repeated friction of the material. It is especially suitable for high-friction scenarios such as sports and long-term wear.

[0032] Preferably, the bra cup 100 is reversible, with both the inner layer 110 and the outer layer 120 made of the same elastic fabric to ensure consistent feel, support, and breathability on both sides. Specifically, in this embodiment, both the inner layer 110 and the outer layer 120 are made of medical-grade high-elasticity fibers (such as warp-knitted mesh fabric with 18% spandex content). By replacing traditional sponge with medical-grade high-elasticity fibers, the drawbacks of sponge materials such as easy bacterial growth, poor breathability, and rapid elasticity loss are solved.

[0033] Preferably, the inner layer 110 and the outer layer 120 have different colors and / or patterns on their outward-facing sides. That is, the inner layer 110 (first surface) and the outer layer 120 (second surface) of the cup 100 are visually distinct through a double-sided reactive dyeing process. This allows the cup 100 to have different colors on different sides, enhancing the user experience. Specifically, in this embodiment, the inner layer 110 of the cup 100 has an invisible breathable mesh structure with a light skin tone base, while the outer layer 120 has a three-dimensional embossed texture with a dark black base.

[0034] It is understandable that in some other embodiments, in order to make the inner layer 110 and the outer layer 120 different colors, the inner layer 110 and the outer layer 120 can also be made of different elastic fabrics. For example, the inner layer 110 made of cotton absorbs color faster and penetrates more easily, while the outer layer 120 made of nylon has a smoother surface and absorbs color more slowly. The different compositions of the outer and inner layers 110 result in different degrees of color absorption, forming a two-tone effect with different shades of color.

[0035] Preferably, the two layers of fabric of the cup 100 are formed by hot pressing to create a cup structure that fits the breast.

[0036] Specifically, in this embodiment, the manufacturing steps of the bra cup 100 are as follows:

[0037] Step 1: Fabric pretreatment, hot pressing the high elastic fiber fabric (warp-knitted mesh structure) into an inner layer 110 and an outer layer 120 with concave portions.

[0038] Step 2: High-temperature molding and shaping. The inner layer 110 and the outer layer 120 are stacked together, and then a CNC hot press is used to perform three molding processes on the cup 100 area to connect the inner layer 110 and the outer layer 120 together, forming a cup 100 with a three-dimensional arc surface that is completely symmetrical between the concave and convex surfaces, and a cavity 130 is also formed inside.

[0039] Step 3: Double-sided dyeing of cup 100, dyeing the inner layer 110 and outer layer 120 of cup 100 with different colors respectively.

[0040] Preferably, the cavity 130 is a roughly circular hollow structure inside the cup 100. After the cup 100 is worn, the position of the cavity 130 is roughly aligned with the nipple of the breast, so that the nipple can reduce friction when wearing the bra.

[0041] It is understood that in some other embodiments, the cavity 130 may also be other structural shapes on the cup 100, such as crescent or star shapes.

[0042] Preferably, the cup 100 is made thinner at the cavity portion 130. By reducing the bonding strength of the inner layer 110 and the outer layer 120 in the central area, a stable cavity structure is more easily formed. Specifically, both layers of fabric in the cup 100 are made thinner at the center, making it easier to form the cavity portion 130 in the middle when the inner layer 110 and the outer layer 120 are stacked and heat-pressed together.

[0043] Preferably, the area of ​​the cavity 130 inside the cup 100 is smaller than the other areas of the cup 100, so that the cup 100 formed by the inner layer 110 and the outer layer 120 can be easily flipped for double-sided use.

[0044] The wearing part 200 is also designed to be reversible, allowing the cups 100 to be used on both sides. For example, the wearing part 200 includes a front flap 210, a back flap 220, and shoulder straps 230, which, together with the cups 100, form a classic bra structure. The cups 100 are positioned on the front flap 210. When the wearing part 200 is worn, the cups 100 are located at the user's breast position to support the breasts. The front flap 210 and the back flap 220 have the same structure. By using this structure, the wearing part 200 can be flipped over and continued to be worn.

[0045] Understandably, see Figure 3 In some other embodiments, the wearing part 200 can also be configured as a strapless structure. For example, the wearing part 200 includes side wings 240, and the reversible bra with anti-friction cups can be a strapless bra structure 230, which includes side wings 240 and cups 100. The side wings 240 are located on both sides of the cups 100 and extend to the back. The side wings 240 are usually made of elastic mesh or widened fabric. The side wings 240 and the cups 100 form a ring-shaped closed structure. The cups 100 are worn on the body through the side wings 240 and are used to support the breasts. Alternatively, the wearing part 200 can also be other front-closure or back-closure side wings, or the wearing part 200 can be a vest style with shoulder straps, as long as the cups 100 can be used on both sides. There are no restrictions here.

[0046] When using the reversible bra with this anti-friction bra cup:

[0047] Put the wearing part 200 over the head and onto the chest area, adjust the cup 100 so that the inner layer 110 of the cup 100 fits the chest, and rotate the cavity 130 of the cup 100 to the nipple position to complete the wearing.

[0048] When wearing it in reverse, turn the entire wearing part 200 (underwear) over so that the inner layer 110 faces outward, and press the outer layer 120 so that its second surface forms a concave surface. Then, put the wearing part 200 over the head and wear it on the chest area. Adjust the cup 100 so that the inner layer 110 of the cup 100 fits the chest and the cavity 130 of the cup 100 is aligned with the nipple position to complete the wearing.

[0049] This invention relates to a reversible anti-friction bra cup. The cavity 130 inside the cup 100 is aligned with the nipple, reducing contact pressure through a 1.0cm buffer space, effectively minimizing skin friction damage. It is particularly suitable for high-friction scenarios such as sports and prolonged wear, preventing skin problems such as redness and itching caused by repeated friction between the cup 100 material and the nipple. High-elasticity fiber fabric (such as warp-knitted mesh and elastic composite fibers) replaces traditional sponge, solving problems such as poor breathability, easy bacterial growth, and rapid loss of elasticity with use associated with traditional sponge materials. Furthermore, the inner layer 110 and outer layer 120 use the same medical-grade high-elasticity fiber, ensuring identical feel, support, and breathability on both sides. Different dyeing processes on each side provide independent visual identification, satisfying users' dual needs for functionality and aesthetics.

[0050] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
