Description

Technical Field

[0001] This utility model relates to the field of underwear technology, and in particular to an environmentally friendly, soft, breathable, and highly elastic underwear sponge cup. Background Technology

[0002] Molded cups are an important component of women's underwear, primarily used to wrap and support a woman's breasts. Currently, the layers of molded cups are connected by adhesive, sewing, or ultrasonic bonding. For molded cups glued with adhesive, the adhesive contains chemicals and obstructs airflow, resulting in poor breathability. For sewn underwear, excessively large sewing areas reduce overall softness, while insufficient sewing areas weaken the bond strength, leading to delamination and making it unsuitable for molded cups filled with sponge. For ultrasonically bonded underwear, high-frequency vibration melts and bonds the material surface to form a covering surface that covers the entire molded cup. Although no adhesive layer is needed, a certain density is required at the bonding points to ensure bond strength. The molten material forms dense solid bonding points that can easily clog the original fabric pores. Reducing the density leads to insufficient interlayer bonding strength, resulting in separation and wrinkles. Furthermore, existing molded cups often employ multi-layered structures, with each layer requiring ultrasonic bonding, resulting in multiple ultrasonically bonded layers. Additionally, the skin-friendly layer of existing molded cups is only located on the inner side of the cup and does not extend to the edge. During wear, the edge of the cup is prone to significant friction with the skin, resulting in poor comfort. Therefore, improvements are necessary. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an environmentally friendly, soft, breathable, and highly elastic bra sponge cup that requires no glue, reduces the connection area, improves breathability and softness, and enhances comfort.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an environmentally friendly soft, breathable, and highly elastic underwear sponge molded cup, comprising an inner lining layer, a support layer, and an outer covering layer arranged sequentially from the inside to the outside. The support layer has multiple breathable mesh holes that penetrate the support layer. The inner lining layer has multiple connecting protrusions on the side facing the support layer. Each connecting protrusion passes through the corresponding breathable mesh hole and is fixedly connected to the outer covering layer. The outer diameter of the connecting protrusion is smaller than the inner diameter of the breathable mesh hole, and there is a breathable gap between the outer side of the connecting protrusion and the inner wall of the breathable mesh hole.

[0005] The outer edge of the inner lining layer is folded towards the outer sheath to form a bend. The bend wraps around the edge of the support layer, and the outer sheath is fixedly connected to the outer side of the bend.

[0006] In a further technical solution, the inner side of the outer cladding layer is provided with multiple connecting grooves, and each of the connecting protrusions is inserted into the corresponding connecting groove.

[0007] In a further technical solution, the inner lining layer includes an inner sponge layer and a skin-friendly layer. The skin-friendly layer is disposed on the inner side of the inner sponge layer, and the connecting protrusion is formed on the outer side of the inner sponge layer. The connecting protrusion and the outer lining layer are connected and fixed by ultrasonic pressing or sewing.

[0008] In a further technical solution, the skin-friendly layer is a skin-friendly layer made of combed cotton and Tencel blend.

[0009] In a further technical solution, the inner surface of the skin-friendly layer is coated with a silver ion antibacterial layer.

[0010] In a further technical solution, the outer layer includes a protective layer and an outer sponge layer, with the protective layer disposed on the outer side of the outer sponge layer and the connecting groove formed on the inner side of the outer sponge layer.

[0011] In a further technical solution, the protective layer is a protective layer made of a blend of milk silk and spandex.

[0012] In a further technical solution, the support layer is a silicone mesh layer, and the breathable mesh is a honeycomb-shaped breathable mesh.

[0013] In a further technical solution, the connecting protrusion is a cylindrical connecting protrusion.

[0014] In a further technical solution, a support strip is provided at the lower part of the support layer. The support strip is located between the support layer and the inner lining layer, and extends along the lower edge of the support layer.

[0015] The advantages of this invention compared to existing technologies are as follows: The inner lining, support layer, and outer covering are connected together by sewing or ultrasonic pressing using connecting protrusions, forming a point-connection structure. This eliminates the need for glue, improving environmental friendliness and reducing the connection area. The multi-point interlocking and positioning solves the problem of interlayer separation and avoids the impact of excessively high density of adhesive layers or ultrasonic hot pressing on breathability, while maintaining both tight connection and breathability. The support layer enhances support and elasticity, and the connecting protrusions passing through the breathable mesh create breathable gaps, further improving breathability. Both the inner lining and outer covering contain sponge, forming a double-layer sponge structure that improves cushioning and softness. The inner lining wraps around the edge of the molded cup with folds, reducing friction between the cup edge and the skin and improving wearing comfort. Attached Figure Description

[0027] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0028] An environmentally friendly, soft, breathable, and highly elastic bra sponge cup includes an inner lining layer 1, a support layer 2, and an outer covering layer 3 arranged sequentially from the inside out. The support layer 2 has multiple breathable mesh holes 21 penetrating through it. The inner lining layer 1 has multiple connecting protrusions 121 on the side facing the support layer 2. Each connecting protrusion 121 passes through the corresponding breathable mesh hole 21 and is fixedly connected to the outer covering layer 3. The outer diameter of the connecting protrusion 121 is smaller than the inner diameter of the breathable mesh hole 21. There is a breathable gap 4 between the outer side of the connecting protrusion 121 and the inner wall of the breathable mesh hole 21. The outer edge of the inner lining layer 1 is folded towards the outer covering layer 3 to form a bent portion 14. The bent portion 14 wraps around the edge of the support layer 2, and the outer covering layer 3 is fixedly connected to the outer side of the bent portion 14. Traditional molded cups, due to their multi-layered structure, require each layer to be joined together using glue or ultrasonic pressing. This results in multiple connecting surfaces and a large connecting area, leading to decreased softness and elasticity, and poor breathability. Furthermore, the use of glue is environmentally unfriendly. This invention, however, uses connecting protrusions 121 to connect the inner lining layer 1, support layer 2, and outer covering layer 3 together using sewing or ultrasonic pressing, forming a point-like connection structure. This eliminates the need for glue, improving environmental friendliness and reducing the connecting area, thus enhancing breathability. The support layer 2 improves support and elasticity, and the connecting protrusions 121 pass through the breathable mesh 21 to form breathable gaps 4, further improving breathability.

[0029] Specifically, the inner surface of the outer layer 3 is provided with a plurality of connecting grooves 321, and each connecting protrusion 121 is inserted into the corresponding connecting groove 321. The connecting grooves 321 increase the connection area between the connecting protrusion 121 and the outer layer 3, thereby improving the connection strength; and when some connecting protrusions 121 cannot be connected by ultrasonic pressing or sewing during connection, they can still be embedded and fixed.

[0030] Specifically, the inner lining layer 1 includes an inner sponge layer 12 and a skin-friendly layer 11. The skin-friendly layer 11 is disposed on the inner side of the inner sponge layer 12, and a connecting protrusion 121 is formed on the outer side of the inner sponge layer 12. The connecting protrusion 121 and the outer covering layer 3 are connected and fixed by ultrasonic pressing or sewing. The inner sponge layer 12 increases softness and cushioning. It is made of memory foam, which has high elasticity and avoids deformation after multiple washes. The skin-friendly layer 11 conforms to the skin, reduces friction between the skin and the skin, and improves comfort.

[0031] Specifically, the skin-friendly layer 11 is a blend of combed cotton and Tencel. The smoothness of Tencel combined with the softness of combed cotton forms a dense fiber structure with a smooth, non-rough surface, thus reducing friction with the skin. Furthermore, the blend of combed cotton and Tencel absorbs moisture faster than pure cotton, providing high breathability. The removal of short fibers by combed cotton, combined with the high dry strength of Tencel, enhances anti-pilling ability, maintaining a smooth finish even after multiple washes and improving durability. The blend of combed cotton and Tencel is 7:3.

[0032] Specifically, the inner surface of the skin-friendly layer 11 is coated with a silver ion antibacterial layer 13. The silver ion antibacterial layer 13 enhances antibacterial properties and prevents bacteria from growing in the warm and humid environment created by sweating.

[0033] Specifically, the outer layer 3 includes a protective layer 31 and an outer sponge layer 32. The protective layer 31 is disposed on the outer surface of the outer sponge layer 32, and the connecting groove 321 is formed on the inner surface of the outer sponge layer 32. The outer sponge layer 32 and the inner sponge layer 12 form a double-layer sponge structure, which improves cushioning and softness. The protective layer 31 wraps around the outer sponge layer 32 to improve abrasion resistance.

[0034] Specifically, the protective layer 31 is made of a blend of milk silk and spandex. The milk silk and spandex blend fabric has a feel similar to cashmere and possesses natural antibacterial properties. Spandex improves extensibility, ensuring a snug fit that is not easily deformed, and also combines the abrasion-resistant and anti-pilling properties of milk silk with the acid and alkali resistance of spandex. The milk silk and spandex are blended in an 8:3 ratio.

[0035] Specifically, the support layer 2 is a silicone mesh layer, and the breathable mesh 21 is a honeycomb-shaped breathable mesh 21. The silicone mesh layer can improve elasticity and support, and improve softness through the mesh physical structure.

[0036] Specifically, the connecting protrusion 121 is cylindrical. The sidewall of the cylindrical connecting protrusion 121 cannot completely fit the inner wall of the honeycomb-shaped breathable mesh 21. Therefore, even after the mold cup is compressed, the breathable gap 4 can still be kept open, preventing the connecting protrusion 121 from deforming and blocking the breathable mesh 21.

[0037] Specifically, a support strip 22 is provided at the lower part of the support layer 2. The support strip 22 is located between the support layer 2 and the inner lining layer 1, and extends along the lower edge of the support layer 2. The support strip 22 can support the chest and create a gathering effect. The support strip 22 is fixed by integral molding or sewing, without the need for glue, thus improving environmental friendliness.

[0038] During production, a skin-friendly layer 11 is made by cutting a blend of combed cotton and Tencel fabric according to the inner lining size of the mold cup. Then, high-elastic memory foam is hot-pressed into an inner sponge layer 12 and an outer sponge layer 32 through a mold, and connecting protrusions 121 and connecting grooves 321 are formed on their surfaces respectively. A pre-made silicone mesh layer is prepared, and the gaps between the honeycomb-shaped breathable mesh 21 of the silicone mesh layer are the same as the gaps between each connecting protrusion 121 and each connecting groove 321. A support strip 22 is fixed at the lower part of the support layer 2 (corresponding to the lower edge of the chest). The support strip 22 is sewn along the lower edge of the support layer 2 by sewing, or the support strip 22 is integrally molded with the support layer 2 by a silicone one-piece molding process. A protective layer 31 is made by cutting a blend of milk silk and spandex fabric according to the outer lining size of the mold cup.

[0039] The skin-friendly layer 11 and the inner sponge layer 12 are composited and fixed together by ultrasonic hot pressing to form the inner lining layer 1. A silver ion antibacterial coating is evenly coated on the inner side of the skin-friendly layer 11 (the side that fits against the skin), and cured by low-temperature drying (60-80℃) to ensure uniform coating thickness, thus obtaining the inner lining layer 1. The protective layer 31 and the outer sponge layer 32 are composited and fixed together by ultrasonic hot pressing to form the outer covering layer 3. The inner lining layer 1 and the support layer 2 are composited and overlapped. The edge of the inner lining layer 1 is folded to form a bend 14, so that the bend 14 wraps around the edge of the support layer 2. Finally, the outer covering layer 3 is stacked. During stacking, a jig is used for auxiliary positioning to ensure that the connecting protrusions 121 pass through the breathable mesh 21 and are inserted into the connecting grooves 321. Then, the connecting protrusions 121 and the bend 14 are fixed by ultrasonic hot pressing. Alternatively, the layers do not need to be connected by ultrasonic hot pressing. After composite stacking, the interlayer is connected by sewing, and the sewn area covers each connecting protrusion 121 and bend 14.

For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
