Description

Technical Field

[0001] This utility model relates to the field of women's underwear technology, specifically to an anti-slip bra. Background Technology

[0002] A bra is a close-fitting garment worn by women to support and protect their breasts. It primarily consists of cups, shoulder straps, underband, and side and back band. Traditional bras typically include underwires and molded cups, designed to support the breasts, shape them, and improve their appearance. However, during wear, bras often shift due to body movement, loss of fabric elasticity, or design flaws, resulting in issues such as shoulder straps slipping, cups riding up, and the underband flipping.

[0003] This displacement not only affects appearance but can also lead to the following problems: the breast loses effective support, fatty tissue spreads to the armpit or back to form accessory breasts, and the breast shape widens or sags; the underwire or hard structure compresses the mammary lymph nodes, which may cause pain or even increase the risk of breast diseases in the long term; friction damage and local pressure occur frequently, leading to a decrease in comfort.

[0004] Existing solutions primarily rely on physical fixation devices to directly suppress relative displacement between the bra and the skin. For example, curved silicone protrusions are placed along the lower inner edge of the cups to replace traditional underwires, with vertically arranged anti-slip bumps (1-3mm high) on the surface. These bumps increase friction with the lower edge of the breast, preventing the cups from shifting upwards. Another approach involves densely arranging hemispherical silicone bumps (1-3mm high) on the inner side of the underband (close to the sternum) to increase friction resistance between the band and the skin, inhibiting lateral slippage. However, these designs have drawbacks: the lower edge of the breast (inframammary fold) has a dense distribution of nerves, and the repeated friction of the 1-3mm silicone bumps during movement can easily cause itching or burning sensations. Furthermore, silicone has poor breathability, and sweat accumulates between the bumps, creating a "suction cup effect" that causes pulling pain when the skin is peeled off. Additionally, the continuous shearing friction between the bump edges and the skin damages the integrity of the stratum corneum, potentially inducing erythema and desquamation, especially in dry / sensitive skin, clinically known as "bra dermatitis."

[0005] Therefore, there is an urgent need for a safe and effective anti-slip solution for bras to improve the many problems existing in current anti-slip solutions. Utility Model Content

[0006] The purpose of this invention is to provide an anti-slip bra that improves the problem of shifting caused by human movement in existing bras by setting anti-slip bands and anti-slip silicone strips inside the cup holders to form a closed ring anti-slip path.

[0007] An anti-slip bra includes an anti-slip band and two cups. Each cup includes a cup support, a side edge, and a lower edge. The two cups are detachably connected. The anti-slip band has a pull tab at each end, which extends upward to cover and connect the lower edge and the side edge. An anti-slip silicone strip is provided on the upper inner side of the cup support. An adjustable interlocking hook and loop fastener is provided at one adjacent end of each of the two cups.

[0008] The anti-slip strip is made of anti-slip elastic fabric with an air-layer weave structure. The outer layer uses 40D / 34F round bright nylon FDY as the yarn; the middle layer (connecting layer) uses 70D spandex as elastic support to ensure the fabric's high resilience and strong tensile strength, enhancing the stability of the side and back sections; the inner layer (anti-slip layer) is woven from anti-slip fibers, forming a textured or air-layer structure that significantly increases friction with the skin.

[0009] The anti-slip band includes two underbands that cover the inner edges of both cups, connecting to the side edges at both ends to form a U-shaped or bridge-like structure. This physical connection forcibly fixes the relative position of the two cups, preventing them from slipping to the sides during exercise. It also covers the inner root of the breast (sternal area) to prevent fat leakage and the formation of accessory breast tissue. The underbands extend upwards to cover the lower edge and inner side edges of the cups, forming a continuous connecting surface. This binds the underbands to the lower edge and side edges of the cups, eliminating the risk of the band rolling up or flipping. The extended surface increases the skin contact area, effectively reducing contact surface pressure and avoiding the localized pressure caused by traditional dotted silicone bumps, while also improving overall stability. Adjustable interlocking buckles are set at the adjacent ends of the two cups (center gore), allowing for free adjustment of the cup spacing according to the distance between the breasts, avoiding compression of the sternum or gaps, and accommodating different breast shapes (outward-spreading / gathered).

[0010] The upper inner side of the bra cups features an anti-slip silicone strip. This strip follows the curve of the lower edge of the breast along the inner side of the cups (near the base of the breast). When the body leans forward (such as bending over), the silicone strip automatically blocks the path of displacement. The anti-slip silicone strip and the anti-slip band work together to form a closed, circular anti-slip path, effectively preventing the bra from shifting during movement.

[0011] This invention forms an integral bridge-type anti-slip structure, upgrading the traditional point-like anti-slip structure to a surface-like anti-slip structure. It suppresses displacement through a mechanical linkage mechanism, replacing the existing reliance on skin friction to prevent displacement, and eliminating the problems of silicone bumps, pressure, and stuffiness. The extended underpart increases the contact area with the skin, effectively dispersing pressure, avoiding local indentations, and improving overall comfort.

[0012] Furthermore, the anti-slip silicone strip assembly is provided in multiple sets, with the silicone strip located at the top of the cup holder being wavy and the silicone strip located on the upper side of the cup holder being arc-shaped.

[0013] The anti-slip silicone strips are provided in two sets, each set consisting of 3 to 8 parallel silicone strips spaced apart. The spacing can be fixed or gradient.

[0014] The undulating structure at the top of the cups forms micro-air cavities. When the breasts bounce, the peaks deform under pressure, absorbing kinetic energy. As the cups tend to move upwards, the angled edges generate a reverse gripping force. The troughs create negative pressure, generating adsorption and cushioning force, maintaining breathable gaps between the skin and preventing stuffiness from a full fit. This effectively reduces the vertical amplitude of breast movement during exercise. The arc-shaped structure on the upper side of the cups follows the distribution of breast ligaments, and the grooves guide underarm fat towards the center of the cups, reducing lateral fat escape during exercise. When the body turns, centrifugal force causes the breasts to move outwards, and the arc-shaped silicone strip creates a curved surface wrapping effect. The inner section (near the sternum) provides static friction, while the outer section (near the armpit) has expanded grooves to increase the contact area and improve the coefficient of friction.

[0015] Furthermore, the connection between the lower part and the lower edge and side edge can be achieved by stitching, bonding, or heat pressing.

[0016] Furthermore, the adjustable interlocking buckle is disposed on the connecting surface between the lower part and the lower edge.

[0017] Furthermore, the adjustable interlocking fastener is a bra fastener and a hook. The bra fastener includes a base fabric and a U-shaped buckle fixed on the base fabric. Multiple U-shaped buckles are provided. The hook is hooked into the U-shaped buckle and then pulled tight to form an interlock.

[0018] Multiple U-shaped buckles are fixed to the base fabric by sewing. There can be 2 to 4 rows of U-shaped buckles, with 1 to 3 buckles in each row. There are also 1 to 3 corresponding hooks. After hooking the corresponding U-shaped buckle, tightening it will form an interlocking mechanism.

[0019] Furthermore, one end of the base fabric and the hook are respectively fixed to the inner side of the lower edge of the two cup portions and the connecting surface of the underband portion, and the other end of the base fabric is connected to the hook through a U-shaped buckle.

[0020] The base fabric is made of high-elastic nylon fabric, which supports the U-shaped buckle array; the U-shaped buckles are made of titanium alloy stamping parts, 3mm wide and 2mm deep;

[0021] The hooks are made of β-type titanium shape memory alloy (15° rebound angle) and self-lock after being hooked in. The adjustment mechanism has been moved from the back to the underband area between the bra cups: shortening the lever arm for easier putting on and taking off; avoiding the sternum to eliminate pressure points.

[0022] Furthermore, interlocking latches are provided at adjacent positions on the two cup holders, and the interlocking latches are located directly above the adjustable interlocking buckle.

[0023] The lower part of the cup uses an adjustable interlocking buckle, and the upper part of the cup uses an interlocking snap fastener. The distance between the two components is 3~5cm.

[0024] Furthermore, the cup holder, side edge, and lower edge are integrally formed to create the cup portion.

[0025] The one-piece molded cup section reconstructs the mechanical transmission path with geometric integrity, effectively improving displacement control, durability, and comfort.

[0026] Furthermore, the connection between the underpart and the cup part on the inner side of the lower edge and side edge can be achieved by stitching, bonding, or heat pressing.

[0027] Furthermore, the bra body is also equipped with shoulder straps.

[0028] Beneficial effects of utility model

[0029] This invention improves the problem of bra shifting due to body movement by setting anti-slip bands and anti-slip silicone strips inside the cups to form a closed, ring-shaped anti-slip path. The underband extends upwards to cover the lower edge and inner side of the cups, binding the underband to the lower edge and side of the cups, eliminating the risk of the band rolling up or flipping. The extended surface increases the skin contact area, avoiding localized pressure caused by traditional dotted silicone bumps, while improving overall stability. Adjustable interlocking clasps are set at the adjacent ends of the two cups (center gore) to avoid squeezing the sternum or leaving gaps, and is compatible with different breast shapes such as outward spread or push-up.

[0034] Example 1: As Figure 1-3As shown, an anti-slip bra includes an anti-slip band 2 and two cup portions 2. Each cup portion 1 includes a cup support 3, a side edge portion 5, and a lower edge portion 4. The two cup portions 1 are detachably connected. The two ends of the anti-slip band 2 are respectively provided with a pull tab 11. The pull tab 11 extends upward to cover and connect the lower edge portion 4 and the side edge portion 5. An anti-slip silicone strip group is provided on the upper inner side of the cup support 3. An adjustable interlocking buckle is provided at one adjacent end of the two cup portions 1.

[0035] The anti-slip band 2 is connected to a cup portion 1 at each end. The cup portion 1 includes a cup holder 3, a side edge portion 5, and a lower edge portion 4. The cup holder 3 supports the main body of the breast, and an anti-slip silicone strip is embedded in the upper inner part. The side edge portion 5 extends outward to cover the underarm fat, with a height ≥7cm. The lower edge portion 4 extends along the lower contour line of the breast, with a width of 2-3cm. The anti-slip band 2 covers the inner edge of the cup portion 1 to form a connection. The anti-slip band 2 includes two underbands 11, each of which extends upward to cover and connect to a cup portion 1. An anti-slip silicone strip is provided on the upper inner part of the cup holder 3. The silicone strip conforms to the lower edge arc of the breast along the inner side of the cup holder 3 (near the root of the breast), and can automatically block the displacement transmission path during movement.

[0036] The two underbands 11 are relatively independent, and each underband 11 extends upward to cover the lower edge 4 and the inner side of the side edge 5 of the corresponding cup part 1, forming a continuous connecting surface; the two ends of the anti-slip band 2 are respectively fixed to the inner edges of the left and right cups, forming a U-shaped bridge-type stable structure. The underbands 11 and the cup part 1 can be connected to each other on the inner side of the lower edge 4 and the inner side of the side edge 5 using a double reinforcement process of hot melt adhesive and ultrasonic welding, or they can be connected by sewing.

[0037] This utility model's anti-slip band 2 is made of anti-slip fabric. The underband 11 of the anti-slip band 2 covers the inner edges of the two cups, and its two ends are connected to the side edges 5 respectively, forming a U-shaped or bridge-like overall structure. This physical connection forcibly fixes the relative positions of the two cups, preventing them from slipping to the sides during exercise. It covers the inner root of the breast (sternal area) to prevent fat leakage and the formation of accessory breast tissue. The underband 11 extends upwards to cover the lower edge 4 and the inner side of the side edges 5 of the cups, forming a continuous connecting surface. This binds the underband 11 to the lower edge 4 and side edges 5 of the cups, eliminating the risk of the band rolling up or flipping, and improving overall stability. Adjustable interlocking buckles are set at the adjacent ends of the two cups (center gore), allowing for free adjustment of the cup spacing according to the distance between the breasts, avoiding compression of the sternum or gaps, and accommodating different breast shapes.

[0038] When wearing the bra, adjust the interlocking clasp to the appropriate size according to your body shape to form an interlocking connection. At this time, under the restriction of the anti-slip band 2, the side edges 5 and lower edges 4 of the cup 1 fit against the wearer's body through the connecting surface formed with the underband 11. At this time, the underband 11 forms an anti-slip contact surface with the wearer, ensuring that the side edges 5 and lower edges 4 of the bra cup 1 maintain stable contact with the wearer's breasts. The anti-slip silicone strip on the upper inner side of the cup forms a stable fit with the base of the breast. During exercise, the underband 11 restricts the side edges 5 and lower edges 4 from shifting relative to the wearer's breasts, and the anti-slip band 2 and anti-slip silicone strip simultaneously restrict the bra in both horizontal and vertical directions, preventing the cup support 3 from shifting between the bra and the wearer's breasts.

[0039] Example 2: As Figure 1-2 As shown, based on Embodiment 1, interlocking snap fasteners are provided at adjacent positions on the two cup holders 3, and the interlocking snap fasteners are located directly above the adjustable interlocking buckle.

[0040] Interlocking buckles are provided at adjacent positions on the two cup holders 3, and the interlocking buckles are located 3cm directly above the adjustable interlocking buckle.

[0041] The snap-fit ​​structure can adopt the following combination: the male snap 9 uses an inverted conical titanium alloy post (3mm in diameter and 2mm in height); the female snap 8 uses a memory silicone ring.

[0042] When wearing the bra, adjust the interlocking clasp to the appropriate size according to your body shape to form an interlocking connection. After inserting the male clasp 9 into the silicone ring, body temperature triggers thermal expansion, causing the aperture to contract and creating an interference fit. At this time, under the constraint of the anti-slip band 2, the side edges 5 and lower edges 4 of the cup 1 fit against the wearer's body through the connecting surface formed with the underband 11. At this time, the underband 11 forms an anti-slip contact surface with the wearer, ensuring that the side edges 5 and lower edges 4 of the bra cup 1 maintain stable contact with the wearer's breasts. The anti-slip silicone strip on the upper inner side of the cup forms a stable fit with the base of the breast. During exercise, the anti-slip band 2 physically connects and forcibly fixes the relative position of the two cups, preventing the cups from sliding to the sides during exercise, covering the inner base of the breast (sternal area), and preventing fat leakage to form accessory breast tissue. The underband is fixedly connected to the lower edge 4 and side edges 5 of the cup 1, eliminating the risk of the band rolling up or flipping. The snap fasteners forcefully maintain the spacing between the inner sides of the cups. When the breast is impacted and moves upward, the snap fasteners pull the upper edge of the cup part 1, forming a net-like effect to prevent the cup part 1 from shifting relative to the breast.

[0043] Example 3: As Figure 1 As shown, based on Embodiment 1, the cup holder 3, the side edge 5, and the lower edge 4 are integrally formed to form the cup portion 1.

[0044] The cup portion 1 is integrally molded using processes such as compression molding, or 3D fused deposition modeling. Thermoplastic polyurethane (TPU) is directionally crystallized in the mold to form a biomimetic mesh structure. The cup curvature is generated through a topology optimization algorithm, ensuring that the overall structural stiffness gradient matches the distribution of breast soft tissue (firm at the bottom and soft at the top), significantly improving support efficiency. The integrally molded cup portion 1 reconstructs the mechanical transmission path with geometric integrity, effectively improving displacement control, durability, and comfort.

[0045] The outer part of the cup is bonded with a skin-friendly fabric, such as cotton, modal, or Lycra, through a heat-pressing process.
