[0001] The utility model relates to a breast pad field, especially a multi-layer structure breast pad for protecting nipples. BACKGROUND

[0002] The breast pad is a pasted object for covering the areola and nipple area, which realizes the invisible shielding effect by adhering to the skin surface, can replace the traditional bra, and has comfort, safety and beauty. The traditional breast pad is mostly made of single-layer silicone or fabric material, and the visual shielding effect is achieved by printing color or pattern on the surface to simulate skin texture. However, the prior art has the following significant defects:

[0003] 1. Poor visual effect: the color of the traditional breast pad is fixed and greatly different from the skin color, the large-area breast pad is transparent when wearing a low-cut outerwear, like a patched clothes, and the small-area breast pad is easy to fall off due to insufficient fitting area.

[0004] 2. Insufficient fitting stability: the existing breast pad has high hardness (Shore A hardness > 40) or uneven thickness distribution (for example, the edge is too thick), which leads to poor curvature adaptation with the chest, and the breast pad is easy to produce edge lifting due to local stress concentration when worn; in addition, the adhesive layer is easily affected by sweat or air penetration, the adhesion decreases, and the breast pad is accidentally fallen off.

[0005] 3. The color of the traditional breast pad is fixed and greatly different from the skin color, the large-area breast pad is transparent when wearing a low-cut outerwear, like a patched clothes, and the small-area breast pad is easy to fall off due to insufficient fitting area.

[0006] 4. The low-hardness silicone material can improve the fitting comfort, but the elastic recovery rate is low (< 80%), which is easy to deform after long-term use, the small-area breast pad has insufficient contact surface and poor adhesion, the large-area breast pad is easy to show through, which is not beautiful, and the adaptability to outerwear is poor, it is difficult to balance the softness, multi-clothing adaptability and structural stability.

[0007] In view of the above problems, it is necessary to develop a breast pad structure with bionic beauty, precise fitting, adjustable function and long-term durability, to solve the conflict between the visual effect, fitting stability and user individualization demand in the prior art. TECHNICAL PROBLEM

[0008] In order to solve the above problems, the utility model provides a multi-layer structure breast pad for protecting nipples.

[0009] The utility model discloses a multi-layer structure breast pad for protecting nipples, which comprises:

[0010] Silicone layer, as the basis of the attached support layer.

[0011] Adhesive layer, arranged on the skin side of the silicone layer, made of biocompatible adhesive material.

[0012] Nano-shielding layer, arranged between the silicone layer and the adhesive layer, or embedded in the internal interlayer of the silicone layer, or attached to the outer layer of the silicone layer.

[0014] Preferably, the side wall of the silicone layer is circumferentially provided with an interlayer cutout, and the nano-shielding layer is embedded in the internal interlayer of the silicone layer through the interlayer cutout.

[0015] Preferably, the thickness of the silicone layer is gradually distributed, the thickness of the central region is 2-3mm, and gradually shrinks to 0.5-1mm towards the edge.

[0016] Preferably, the silicone layer is a translucent material, and the visible light transmittance is greater than or equal to 70%, and the haze is less than or equal to 25%.

[0017] Preferably, the nano-shielding layer is made of nano-scale composite material, and the visible light transmittance is less than 10%.

[0018] Preferably, the thickness of the nano-shielding layer is 0.05-0.15mm.

[0019] Preferably, the nano-shielding layer is printed on the outer surface of the silicone layer or the inner surface of the silicone layer by using environmentally friendly ink material.

[0020] Preferably, the adhesive layer is a composite adhesive made of AB glue and hot melt adhesive, and the surface is provided with a peelable protective film.

[0021] Preferably, the material of the silicone layer is selected from at least one of silicone gel and solid silicone, the Shore A hardness is 10-30, the tensile strength is greater than or equal to 5MPa, and the surface has a micro-convex structure suitable for the curvature of the human chest.

[0022] Preferably, the adjacent cutout surfaces of the interlayer cutout form a biomimetic closed structure, and when the nano-shielding layer is embedded in the internal interlayer of the silicone layer, the elastic recovery of the silicone layer forms an automatic reset closed cutout.

[0023] The utility model discloses a multi-layer composite structure, solves the problem of traditional breast paste, and the specific technical effects are as follows:

[0024] 1. High light shielding compatibility with natural appearance: Nano-shading layer (transmittance <10%) combined with high transparent silicone layer (transmittance ≥80%), achieving full-band light shielding in extremely thin thickness (0.05-0.15mm), completely hiding the nipple contour and avoiding the "light transmission embarrassment" of traditional breast pasties; interface fusion technology of nano material and transparent silicone eliminates the color difference and boundary feeling between the shading layer and the substrate, visually closer to the natural skin color, and adapts to different light transmittance clothing scenes.

[0025] 2. Precise fitting and stability improvement: Gradual thickness silicone layer (2-3mm in the center, gradually shrinking to 0.5-1mm at the edge) matches the curvature of the human chest, reducing edge stress concentration and avoiding the problem of edge lifting caused by uneven thickness; low hardness silicone material (Shore A hardness 10-30) provides flexibility, combined with bionic interlocking structure to ensure that the interlayer incision is tightly closed, preventing air infiltration and falling risk; biocompatible adhesive layer (AB glue and hot melt glue composite) enhances the long-lasting adhesion, resists sweat and slight friction, and improves the wearing stability.

[0026] 3. Comfort and durability optimization: Low hardness silicone layer (10-30A) fits the skin without compression, reducing wearing fatigue; high elastic recovery rate (≥90%) ensures that the structure remains intact after repeated disassembly or deformation, avoiding the deformation failure problem caused by softening of traditional breast pasties.

[0027] 4. Process simplification and cost control: Nano-shading layer is directly embedded in the silicone substrate interlayer, using printing process to form nano-shading layer, improving production efficiency.

[0028] The utility model discloses through material innovation (nano-shading layer + gradual silicone), structure optimization (bionic interlocking + detachable interlayer) and function integration (shading / ventilation / adjustable), which is significantly superior to the prior art in privacy protection, wearing comfort, user autonomy and product durability, and has high market application value.

The material of the silicone layer 1 is selected from at least one of silicone gel and solid silicone, and the surface thereof has a micro-convex structure adapted to the curvature of the human chest.

[0041] The specific structure is as follows:

[0042] 1. Silicone layer 1 preparation: translucent silicone gel mold forming, central area thickness 2.5mm, gradually changing to 0.8mm towards the edge, surface design micro convex curvature to fit the human chest;

[0043] 2. Nano blocking layer 2 processing: cut the nano composite material (polyurethane film containing light shielding particles) into a circle with a diameter of 40mm and a thickness of 0.1mm, visible light transmittance ≤8%;
