Description

Technical Field

[0001] This utility model relates to the field of bra accessories, and in particular to a plastic breast pad with a hidden arch support. Background Technology

[0002] As a type of women's intimate apparel, the primary function of a bra is to protect the breasts and prevent sports injuries, while also serving to enhance body shape. The applicant developed and applied for a patent for an elastic rubber breast pad with an embedded plastic arch, with authorization announcement number CN209235024U and announcement date August 13, 2019. This elastic rubber breast pad with an embedded plastic arch includes an elastic rubber breast pad body and a plastic arch; the lower edge of the elastic rubber breast pad body has an arc-shaped extension, which is integrally injection molded with the elastic rubber breast pad body, and the entire plastic arch is embedded in the arc-shaped extension. Although this elastic rubber breast pad can adapt to the contour of the breast and effectively support the female user's breasts, the injection molding process and steps for the embedded plastic arch are relatively difficult. Furthermore, when the female user exercises, the embedded plastic arch still feels hard, and there is a possibility that the embedded plastic arch may bounce upwards and dislodge during exercise. Utility Model Content

[0003] The problem to be solved by this utility model is to provide a plastic breast pad with a hidden arch support. This plastic breast pad with a hidden arch support is simple to injection mold and can effectively support the breasts of female users.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A concealed arch support plastic breast pad includes an elastic rubber breast pad body and an elastic rubber support part, characterized in that: the elastic rubber support part includes an integrally injection-molded arc-shaped arch support and an arc-shaped undercut; the lower part of the elastic rubber breast pad body is provided with an arc-shaped notch that matches the arc-shaped arch support, the arc-shaped arch support is located in the arc-shaped notch, and the upper end face of the arc-shaped arch support is fused to the edge of the arc-shaped notch; the rigidity of the arc-shaped arch support is greater than the rigidity of the elastic rubber breast pad body.

[0006] The inner side of the aforementioned elastic rubber support portion and the remaining portion of the inner side of the elastic rubber breast pad body together constitute the inner side of the concealed arch support plastic breast pad, and the outer side of the elastic rubber support portion and the outer side of the elastic rubber breast pad body constitute the outer side of the concealed arch support plastic breast pad.

[0007] The upper half of the aforementioned elastic rubber breast pad is thinner, while the lower half is thicker. This concealed arch support plastic breast pad forms a cup shape that is thinner at the top and thicker at the bottom. The more rigid elastic rubber support is located on the lower half of the elastic rubber breast pad. The injection-molded curved arch support is relatively soft, allowing it to fit snugly against the user's skin, effectively lifting the breasts without causing a feeling of hardness. This prevents the embedded plastic arch from bouncing upwards and slipping out. The curved underband supports the elastic rubber breast pad, preventing breast sagging and gently moving loose fat around the breasts into the breast tissue. Furthermore, the upper surface of the curved arch support and the edge of the curved notch are directly welded together, simplifying the injection molding process.

[0008] In a preferred embodiment, the inner surface of the arc-shaped support is provided with an inwardly protruding arc-shaped ridge. This arc-shaped ridge simulates the natural curvature of the lower edge of a female user's breast, conforming to the pectoralis major muscle and distributing support evenly across the breast base, reducing localized pressure.

[0009] In the preferred embodiment, the thickness of the arc-shaped support gradually decreases from the middle to both ends. The thinning design at both ends of the arc-shaped support allows for a smooth transition between the edge of the support and the main body of the breast pad, eliminating any bulges when wearing tight clothing. It also conforms to the natural curvature from the lower edge of the breast to the ribs, avoiding friction damage in the armpit area caused by traditional uniform-thickness support.

[0010] In the preferred embodiment, the rigidity of the arc-shaped support is greater than that of the arc-shaped underarm. The arc-shaped support bears the main lifting force, while the low-rigidity design of the arc-shaped underarm maintains elasticity and deformability, allowing it to adaptively conform to the dynamic displacement of the breast during movement, reducing the restrictive feeling of traditional rigid integrated structures.

[0011] In a preferred embodiment, each end of the arc-shaped notch is provided with a downward-facing U-shaped weld joint, and each end of the arc-shaped arch support is provided with a U-shaped piece that matches the corresponding U-shaped weld joint. The U-shaped piece is located within the corresponding U-shaped weld joint, and the upper edge of the U-shaped piece is welded to the edge of the corresponding U-shaped weld joint. The snap-fit ​​engagement between the U-shaped piece and the U-shaped weld joint increases the welding area, maintains stable support performance of the plastic breast pad during long-term use, and effectively solves the problem of traditional embedded plastic arches coming loose.

[0012] In a preferred embodiment, multiple first through holes are formed between the inner and outer surfaces of the elastic rubber breast pad body. The inner opening of each first through hole covers the entire inner surface of the elastic rubber breast pad body, and the outer opening of each first through hole covers the entire outer surface of the elastic rubber breast pad body. The presence of these first through holes within the elastic rubber breast pad body ensures that the entire elastic rubber breast pad body is breathable while maintaining elasticity, pressure resistance, and shaping properties, thereby reducing the weight of the bra.

[0013] In a further preferred embodiment, the diameter of the inner opening of the first through hole is larger than the diameter of the outer opening. The diameter of the inner opening of the first through hole can be further enlarged compared to existing diameters, thereby improving breathability and reducing the weight of the elastic rubber breast pad body.

[0014] In a further preferred embodiment, there is an annular step between the outer end of the inner opening of the first through hole and the inner end of the outer opening.

[0015] In a preferred embodiment, multiple second through holes are formed between the inner and outer surfaces of the arc-shaped arch support. These second through holes are distributed along the length of the arc-shaped arch support, with the inner opening of each second through hole located on the inner surface and the outer opening on the outer surface. The presence of multiple second through holes within the elastic rubber support ensures breathability while maintaining elasticity, compressive strength, and shaping properties, thus reducing its weight. During injection molding, the elastic rubber breast pad body and the elastic rubber support are respectively injection molded in two molds. After the elastic rubber support is formed, positioning pins in the injection mold are positioned in the corresponding second through holes on the elastic rubber support, facilitating its transfer to another mold for welding with the elastic rubber breast pad body.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This type of concealed arch support plastic breast pad is simple to injection mold and can effectively lift women's breasts without the need for an underwire. It maintains the overall softness of the bra pad and gives it a certain degree of firmness. It changes the long-standing structure of bras that require underwires or wires to lift the breasts, and will not cause pressure on women's breasts, making it more conducive to enhancing the breast shape.

[0020] Figure 3 yes Figure 2 Cross-sectional view of AA. Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-3As shown, the concealed arch support plastic breast pad in this embodiment includes an elastic rubber breast pad body 1 and an elastic rubber support part 2. The elastic rubber support part 2 includes an integrally injection-molded arc-shaped arch support 21 and an arc-shaped undercut 22. The lower part of the elastic rubber breast pad body 1 is provided with an arc-shaped notch 11 that matches the arc-shaped arch support 21. The arc-shaped arch support 21 is located in the arc-shaped notch 11, and the upper end face of the arc-shaped arch support 21 is fused with the edge of the arc-shaped notch 11. The rigidity of the arc-shaped arch support 21 is greater than the rigidity of the elastic rubber breast pad body 1.

[0023] The inner side of the elastic rubber support part 2 and the remaining part of the inner side of the elastic rubber breast pad body 1 together constitute the inner side of the plastic breast pad with hidden arch support, and the outer side of the elastic rubber support part 2 and the outer side of the elastic rubber breast pad body 1 constitute the outer side of the plastic breast pad with hidden arch support.

[0024] The upper half of the aforementioned elastic rubber breast pad body 1 is thinner, while the lower half is thicker. This concealed arch support plastic breast pad forms a cup shape that is thinner at the top and thicker at the bottom. The more rigid elastic rubber support part 2 is placed on the lower half of the elastic rubber breast pad body 1. The elastic rubber injection-molded arc-shaped arch support 21 is relatively soft, allowing it to fit snugly against the skin of the female user, effectively lifting the breasts and preventing the user from feeling any hardness. This avoids the problem of the embedded plastic arch bouncing upwards and slipping out. The arc-shaped undercut 22 supports the elastic rubber breast pad body 1, preventing breast sagging and gradually moving loose fat around the breasts into the breast tissue. Furthermore, the upper surface of the arc-shaped arch support 21 and the edge of the arc-shaped notch 11 are directly welded together, simplifying the injection molding process.

[0025] The inner side of the arc-shaped support 21 is provided with an inwardly protruding arc-shaped ridge 211. The aforementioned arc-shaped ridge 211 simulates the natural curvature of the lower edge of a female user's breast, conforms to the pectoralis major muscle, and distributes the support force evenly at the base of the breast, reducing local pressure.

[0026] The thickness of the curved support 21 gradually decreases from the middle to both ends. The thinning design at both ends of the curved support 21 allows the edge of the curved support 21 to transition smoothly with the breast pad body, without any bulges when wearing tight clothing. It adapts to the natural curvature change from the lower edge of the breast to the ribs and avoids friction damage in the armpit area caused by traditional uniform thickness support.

[0027] The rigidity of the arc-shaped support 21 is greater than that of the arc-shaped underarm 22. The arc-shaped support 21 bears the main supporting force, while the low rigidity design of the arc-shaped underarm 22 can maintain elasticity and deformability. During movement, the arc-shaped underarm 22 adapts to the dynamic displacement of the breast and fits the body, reducing the restrictive feeling of traditional rigid one-piece structures.

[0028] The arc-shaped notch 11 has U-shaped weld joints 111 with downward openings at both ends. The arc-shaped arch support 21 has U-shaped pieces 212 at both ends that match the corresponding U-shaped weld joints 111. The U-shaped pieces 212 are located in the corresponding U-shaped weld joints 111, and the upper edge of the U-shaped pieces 212 is welded to the edge of the corresponding U-shaped weld joint 111. The snap-fit ​​engagement between the U-shaped pieces 212 and the U-shaped weld joints 111 increases the welding area, maintains stable support performance of the plastic breast pad during long-term use, and effectively solves the problem of traditional embedded plastic arches coming out.

[0029] The elastic rubber breast pad body 1 has multiple first through holes 112 between its inner and outer surfaces. The inner opening 1121 of each first through hole 112 covers the entire inner surface of the elastic rubber breast pad body 1, and the outer opening 1122 of each first through hole 112 covers the entire outer surface of the elastic rubber breast pad body 1. The presence of these first through holes 112 throughout the elastic rubber breast pad body 1 ensures that the entire elastic rubber breast pad body 1 is breathable while maintaining elasticity, pressure resistance, and shaping properties, and also reduces the weight of the bra.

[0030] The diameter of the inner opening 1121 of the first through hole 112 is larger than the diameter of the outer opening 1122. The diameter of the inner opening 1121 of the first through hole 112 can be further enlarged compared with the existing diameter, thereby improving breathability and reducing the weight of the elastic rubber chest pad body 1.

[0031] An annular step 1123 is provided between the outer end of the inner opening 1121 of the first through hole 112 and the inner end of the outer opening 1122.

[0032] Multiple second through holes 213 are formed between the inner and outer surfaces of the arc-shaped arch support 21. Each second through hole 213 is distributed along the length of the arc-shaped arch support 21. The inner opening 1121 of each second through hole 213 is located on the inner surface of the arc-shaped arch support 21, and the outer opening 1122 of each second through hole 213 is located on the outer surface of the arc-shaped arch support 21. The multiple second through holes 213 within the elastic rubber support 2 allow for breathability while maintaining elasticity, pressure resistance, and shaping properties, and also reduce the weight of the elastic rubber support 2. During injection molding, the elastic rubber breast pad body 1 and the elastic rubber support 2 are injection molded in two separate injection molds. After the elastic rubber support 2 is injection molded, the positioning pins in the injection mold are positioned in the corresponding second through holes 213 on the elastic rubber support 2, facilitating its transfer to another injection mold for welding with the elastic rubber breast pad body 1.
