Description

Technical Field

[0001] This utility model relates to the field of intimate apparel technology, specifically to an underwear with different longitudinal elongation lengths. Background Technology

[0002] Some women with full breasts find that ordinary bras cannot distribute the pressure well, leading to a heavy burden on their shoulders and back. However, bras with different vertical stretch lengths are uniquely designed to reduce shoulder and back pressure and provide comfortable wear. Pregnant and breastfeeding women experience changes in their breasts and have sensitive skin, making traditional bras difficult to adapt to. This bra can flexibly adapt to changes in breast size, and its skin-friendly material reduces skin irritation. For active women, whose movements are large and whose breasts move significantly, ordinary bras lack stability and fit. This bra has a special design that reduces breast movement and has excellent breathability to keep them dry and comfortable.

[0003] The bra straps are typically made of a blend of spandex and nylon. The high elasticity of spandex allows the straps to adapt to shoulder movement, while nylon ensures abrasion resistance. Some straps are made of cotton on the skin-contacting side for enhanced skin-friendliness and moisture absorption. Plastic buckles facilitate length adjustment and distribute the bra's weight to prevent slippage. The main body is mostly made of a breathable blend of modal and spandex. Modal is soft, smooth, and has good moisture absorption, while spandex provides elasticity to avoid tightness. Some sections use mesh or lace to enhance breathability and style. The cups contain elastic metal support strips designed to conform to the curves of the bust, offering excellent resilience and support to lift the bust and prevent sagging. The outer layer is covered with breathable and elastic fabrics such as a nylon-spandex blend and lace, working in conjunction with the underwire to ensure the skin of the bust can breathe. It combines a comfortable fit with shaping effects, making it both practical and comfortable overall.

[0004] Existing technologies still have some shortcomings: Firstly, some women need to use breast pads, but existing breast pads will shift if not properly secured, affecting their effectiveness. This problem is quite troublesome even when used with bras of different lengths. Since individual body shapes, breast shapes, and desired levels of breast enhancement vary, the size, thickness, shape, and material of breast pads should also differ. To meet diverse needs, a breast pad design and supporting technology is needed that can flexibly adjust the size, shape, thickness, and material of breast pads according to individual women's body characteristics, breast shapes, and specific usage scenarios, while having a reliable securing method to prevent displacement during use. This would allow for a perfect fit with bras of different lengths, providing women with a more comfortable, personalized, and stable wearing experience. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide underwear with different longitudinal elongation lengths to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bra with different longitudinal elongation lengths, comprising a bra body and a cup. The bra body is composed of two sets of lace surface layers. A connecting area is sewn between the two sets of lace surface layers by a sewing thread. An accommodating cavity is provided inside the lace surface layer, with the opening of the accommodating cavity facing downwards. Chain teeth are sewn to both sides of the outer wall of the lace surface layer at the opening of the accommodating cavity by a sewing thread. A pull tab is connected to the outer wall of the two sets of chain teeth at the middle position away from the connecting area. A retaining strip is sewn to the outer wall of the two sets of chain teeth away from the pull tab and located on the outer wall of the lace surface layer by a sewing thread. A silicone strip is glued to the outer wall of the retaining strip near the chain teeth.

[0007] By adopting the above technical solution, the breast pad is first filled into the opening below the cup. After the breast pad is completely filled into the receiving cavity, it needs to be adjusted to prevent the breast pad from bending. Then, the pull head is moved to connect the two side chain teeth to close the receiving cavity, thereby achieving stable positioning of the breast pad, preventing the breast pad from falling or shifting, and improving the stability of the breast pad during use.

[0008] Furthermore, the interior of the lace surface layer is provided with multiple sets of support strips made of elastic metal, and each set of support strips supports the overall shape and curvature of the bra cup.

[0009] By adopting the above technical solutions, the support strip can provide stable support and shaping effect for the bra cup.

[0010] Furthermore, a pure cotton layer is sewn onto the outer curved surface of the lace layer close to the user's chest by sewing thread. Memory foam is laid and filled inside the lace layer and on the outer wall of the pure cotton layer near the receiving cavity, and the memory foam is evenly laid along the curved surface of the cup that fits the user's chest.

[0011] By adopting the above technical solution, the pure cotton layer fits the user's chest, utilizing its excellent moisture absorption to quickly absorb sweat from the skin's surface, keeping the skin dry and comfortable, reducing discomfort and potential skin problems caused by sweat accumulation. The memory foam is evenly laid along the curve of the cup against the user's chest, closely conforming to the chest curve and providing a comfortable cushioning and enveloping feel. Furthermore, memory foam has a slow rebound characteristic; when subjected to pressure from the chest, it gradually deforms according to the magnitude and distribution of pressure, precisely conforming to every undulation of the chest. This fit effectively reduces gaps between the bra and the chest, preventing empty cups and ensuring the chest is fully contained within the cups. Moreover, the cushioning effect of memory foam reduces the impact of external pressure on the chest, providing extra protection during exercise or physical activity, and absorbing vibrations to prevent discomfort caused by excessive chest movement.

[0012] Furthermore, the top of the main body of the underwear is sewn with a shoulder strap, and the main body of the shoulder strap is made of spandex fabric, while the edges of the shoulder strap are sewn with polyester fabric.

[0013] By adopting the above technical solution, polyester fabric is sewn onto the edges of the shoulder straps to enhance their tensile strength and prevent the bra from tearing due to excessive stretching. In addition, the outer wall of the shoulder straps is equipped with adjustment buckles to adjust the length of the shoulder straps, making them suitable for users of different body types.

[0014] Furthermore, an elastic band is sewn to the narrowed bottom of the main body of the underwear with sewing thread.

[0015] By adopting the above technical solution, the bottom of the bra body is narrowed and sewn with an elastic band, which can fit snugly against the user's waist to fix the position of the bra and prevent it from slipping up. At the same time, it can moderately tighten the waist and create a more body-fitting wearing effect.

[0016] Furthermore, the back of the main body of the underwear features an inverted triangle back opening design, and the back fabric is made of elastic mesh fabric.

[0017] By adopting the above technical solution, the back of the underwear body is provided with an inverted triangular elastic mesh fabric, which can reduce the area of ​​the user's back that is covered, allowing the user to cool down quickly.

[0018] In summary, the present invention has the following main advantages:

[0019] This invention involves first filling the bra pad into the opening below the cup. After the pad is fully inserted into the receiving cavity, adjustments are made to prevent it from bending. Then, the zipper pull is moved to connect the two side zipper teeth, closing the receiving cavity and achieving stable positioning of the bra pad. This prevents the pad from falling or shifting, improving its stability during use. After the receiving cavity is closed, the side guards connect with the silicone strip and cover the zipper pull and zipper teeth to prevent them from scratching the user. The silicone strip provides a certain amount of support strength to the opening, preventing the bottom of the cup from deforming due to compression and causing the zipper teeth to break, thus improving the connection strength.
