TECHNICAL FIELD
[0001] The utility model relates to a bra underwear product technical field, especially a bra traceless side wing. BACKGROUND
[0002] The existing bra design often adopts the traditional rigid band structure in the side wing part, which can provide support to a certain extent, but has many shortcomings. First of all, the traditional rigid band is usually made of hard material, which can easily cause compression to the skin when worn, and long-term wearing may cause discomfort or skin damage. Secondly, the fixing method of the rigid band depends on the sewing process, which not only increases the production complexity and cost, but also may affect the appearance and wearing experience due to uneven stitches. In addition, the traditional design lacks differentiation in the needs of different body areas, resulting in poor overall support effect, especially in key areas such as under the breast that need more support, which often fails to provide sufficient support.
[0003] In order to solve these problems, various improved schemes have appeared in the market, such as using elastic material to replace the rigid band to increase comfort and air permeability. However, these schemes usually do not fully consider the specific needs of each area, resulting in insufficient support in some areas and excessive looseness in other areas, which cannot achieve the ideal balance of fit and support. In addition, the existing design scheme still has defects in edge processing, and the complex hemming or sewing process not only increases the manufacturing difficulty, but also may affect the durability and appearance of the product.
[0004] Publication No. CN204861224U discloses a bra traceless side wing, which includes an outer side wing and an inner side wing, and further includes a rigid band and a film. The width of the outer side wing is greater than that of the inner side wing. The upper and lower edges of the outer side wing are folded inward and seamlessly butted with the upper and lower edges of the inner side wing. The inner side of the seamless butt joint of the upper and lower edges of the outer side wing and the inner side wing is provided with a rigid band and a film. However, this technical scheme still has the problems of large pressure at the rigid band, insufficient overall support, poor use effect, and complex hemming in the production process, which increases the manufacturing difficulty.
[0005] Therefore, there is an urgent need for a new bra traceless side wing design to overcome the above technical problems. SUMMARY
[0006] Therefore, there is an urgent need for a new bra traceless side wing design to overcome the above technical problems.
[0007] To achieve the above purpose, the technical scheme of the utility model is as follows:
[0008] A bra traceless wing comprises an outer wing, an inner wing, an elastic net and two layers of adhesive film; the outer wing, the adhesive film, the elastic net, the adhesive film, the inner wing are sequentially arranged from outside to inside; the width of the outer wing is equal to the width of the inner wing, and the width of the outer wing is smaller than the width of the elastic net.
[0009] Further, the elastic net comprises a first connecting part and a second connecting part, the first connecting part is connected with the second connecting part, the first connecting part is uniformly distributed with first mesh holes, the second connecting part is uniformly distributed with second mesh holes, and the density of the first mesh holes is greater than the density of the second mesh holes.
[0010] Further, the ratio of the density of the first mesh holes to the density of the second mesh holes is 1: (2-2.5).
[0011] Further, the shape of the first mesh holes and the second mesh holes is diamond or circular.
[0012] Further, the first connecting part connects the lower edge of the wing, and the second connecting part connects the upper edge of the wing.
[0013] Further, the width of the outer wing is 5-15mm smaller than the width of the elastic net.
[0014] Further, the outer wing, the inner wing, the elastic net and the two layers of the adhesive film are connected by hot pressing or ultrasonic welding technology.
[0015] Further, it further comprises a glue bone, the glue bone is vertically arranged along the wing, and is used for enhancing the supporting force of the wing.
[0016] Further, the glue bone is provided at least two, the glue bone is in the form of a narrow sheet, the length of the glue bone is three fourths of the width of the wing, and the thickness of the glue bone is the same as the thickness of the elastic net.
[0017] Further, the upper and lower edges of the elastic net are provided with boundary lines, and the boundary lines are used for determining the mounting positions of the outer wing, the inner wing and the adhesive film.
[0018] Compared with the prior art, the bra traceless wing has the following advantages:
[0019] 1. This utility model uses an elastic mesh instead of a bra insert, increasing the contact area between the bra wings and the body during wear, reducing local pressure, improving wearing comfort, and contributing to a better user experience. It also significantly increases the lifespan of the wings. The width of the outer wing is set smaller than the elastic mesh, avoiding complex processing of the edges of the outer and inner wing during the bonding process. It eliminates the need for sewing or folding, further simplifying the production process, significantly improving production efficiency, and helping to achieve a smoother, seamless appearance.
[0020] 2. This utility model achieves precise support distribution by subdividing the elastic mesh into a first connecting part and a second connecting part, and setting different mesh densities in different areas. The high-density mesh area provides stronger support, effectively disperses pressure and reduces local stress points, preventing discomfort or skin damage caused by long-term wear; the low-density mesh area provides better breathability and flexibility, allowing the wearer to move more freely.
[0021] 3. This utility model pre-embeds the glue into an elastic mesh and fixes it using hot pressing or ultrasonic welding technology, making the entire structure firm, smooth and seamless. This not only simplifies the production process but also reduces manufacturing costs and improves production efficiency.
[0022] 4. This utility model, through the selection of elastic mesh material and its partition design, not only improves the functionality of the product, but also enhances its durability and aesthetics. The glue is embedded in the elastic mesh and fixed by modern welding technology, ensuring a tight connection and smooth transition between materials, avoiding unsightly marks that may be caused by traditional sewing stitches. In addition, the wider design of the elastic mesh can, to a certain extent, wrap around the edges of the outer wings, playing a protective role and extending the service life of the product.

[0032] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0033] This utility model discloses a seamless side wing for a bra, which includes an outer side wing 1, an inner side wing 2, an elastic mesh 3, and two layers of adhesive film 4;
[0034] The outer wing 1, the adhesive film 4, the elastic mesh 3, the adhesive film 4, and the inner wing 2 are arranged sequentially from the outside to the inside;
[0035] The width of the outer wing 1 is equal to the width of the inner wing 2, and the width of the outer wing 1 is less than the width of the elastic net 3.
[0036] By setting the outer side wing 1 and the inner side wing 2 to have the same width, it is convenient to cut the material and improves processing efficiency. By using elastic mesh 3 instead of traditional bra straps, the area of force between the side wings and the body is increased when the bra is worn, reducing local pressure and improving wearing comfort, which helps to obtain a better user experience. It also greatly increases the service life of the side wings. The width of the outer side wing 1 is set to be smaller than that of the elastic mesh 3, which avoids complex processing of the edges of the outer side wing 1 and the inner side wing 2 during the bonding process. There is no need to use sewing or folding processes, which further simplifies the production process, significantly improves production efficiency, and helps to achieve a smoother and more seamless appearance.
[0037] Specifically, the elastic mesh 3 includes a first connecting part 301 and a second connecting part 302. The first connecting part 301 is connected to the second connecting part 302. The first connecting part 301 is evenly distributed with first mesh holes 303, and the second connecting part 302 is evenly distributed with second mesh holes 304. The density of the first mesh holes 303 is greater than the density of the second mesh holes 304.
[0038] The first connecting section 301, with its low mesh density, is located in areas requiring more support, such as under the side wings or near the chest. Lower mesh density means a larger material contact area, providing stronger support and stability, and distributing pressure more evenly across specific areas, reducing localized stress points and preventing discomfort or skin damage from prolonged wear. The second connecting section 302, with its high mesh density, is suitable for areas requiring greater flexibility and breathability, such as the upper or edge parts of the side wings. Higher mesh density allows for greater stretch and airflow.
[0039] This design significantly improves wearer comfort by precisely controlling the support strength and breathability of each part, helps enhance the abrasion resistance and tensile strength of these areas, and achieves better support, greater comfort, and a longer service life, while also taking into account aesthetics.
[0040] Preferably, the outer dimensions of the first mesh 303 are the same as those of the second mesh 304.
[0041] Specifically, the ratio of the density of the first mesh 303 to the density of the second mesh 304 is 1:(2-2.5).
[0042] This setting sets the density of the first mesh 303 to the density of the second mesh 304 in a ratio of 1:(2-2.5), which optimizes breathability and flexibility while ensuring necessary support, thereby improving wearer comfort and satisfaction and helping to extend the product's lifespan.
[0043] Specifically, the first mesh 303 and the second mesh 304 are rhomboid or circular in shape.
[0044] The diamond-shaped mesh structure allows it to maintain its shape under significant tensile force, effectively distributing pressure points, especially in low-density areas such as the first connecting part 301, thus providing stronger support. Diamond-shaped meshes typically have good elasticity, allowing them to deform slightly according to body movement, better conforming to the body's curves, particularly in areas requiring a greater range of motion. The diamond-shaped mesh creates effective ventilation paths, helping to expel moisture and increase airflow, enhancing wearing comfort. Furthermore, the diamond-shaped mesh is aesthetically pleasing.
[0045] Due to their symmetry, the circular mesh can distribute the pressure applied to it very evenly, making them ideal for areas that require balanced support. The rounded edges reduce friction against the skin, increasing the softness and comfort of wearing them. They also easily return to their original shape after being stretched, giving the material better elasticity and durability.
[0046] Specifically, the first connecting part 301 connects to the lower edge of the side wing, and the second connecting part 302 connects to the upper edge of the side wing.
[0047] The lower edge of the side wings typically requires more support to provide good support under the chest. By using a lower-density first mesh 303 in this area, stability and support are enhanced, while the upper edge of the side wings focuses more on comfort and breathability. The higher-density mesh provides better flexibility and airflow, allowing the wearer greater freedom of movement.
[0048] This design provides extra support in key areas while remaining soft and flexible in other areas, reducing the pressure or discomfort that may be caused by prolonged wear, promoting ventilation and sweat-wicking, and improving the wearer's overall comfort.
[0049] Specifically, the material of the elastic mesh 3 can be one or more of silicone, nylon, polyester, spandex or polyurethane.
[0050] The above materials each have their unique functions and advantages. They can be used alone or in combination. By rationally selecting and combining these materials, not only can the functionality of the product be improved, but the wearing experience can also be enhanced, meeting the needs of different consumers.
[0051] Specifically, the width of the outer wing 1 is 5-15mm smaller than the width of the elastic net 3.
[0052] The portion of the elastic mesh 3 extending beyond the outer side wing 1 provides additional coverage and support, especially in areas requiring more support, such as under or on the sides of the breast. This helps distribute pressure and reduce localized stress points. The wider design of the elastic mesh 3 can partially cover the edges of the outer side wing 1, providing protection and reducing edge wear caused by daily wear, thus extending the product's lifespan. It also contributes to a smoother, seamless appearance, making the product look more refined and upscale, meeting modern consumers' aesthetic demands for lingerie. Because the width of the outer side wing 1 is smaller than the elastic mesh 3, no additional folding or other complex edge treatments are needed for the outer side wing 1, simplifying the production process and reducing production costs. Without the need for complex processes like sewing or folding, it can be directly bonded using the adhesive film 4, significantly simplifying the cutting and assembly steps in the production process and improving production efficiency.
[0053] Meanwhile, the elastic mesh 3 can also increase the friction between the bra and the body, resulting in better performance.
[0054] Specifically, the upper and lower edges of the elastic mesh 3 have no mesh openings.
[0055] The non-mesh portion acts as an additional protective layer, covering and protecting the edges of the outer wing 1 to prevent wear and tear caused by daily wear. The non-mesh area is typically smoother, reducing friction with skin or other clothing and lowering the risk of abrasion. This smoother, more seamless finish enhances the overall aesthetics of the final product.
[0056] Specifically, the upper and lower edges of the elastic mesh 3 are provided with boundary lines, which are used to determine the installation positions of the outer wing 1, the inner wing 2, and the two layers of adhesive film 4.
[0057] The boundary line provides clear installation reference points for the outer side wing 1, the inner side wing 2, and the two layers of adhesive film 4, ensuring that the materials of each layer can be accurately aligned, reducing errors caused by manual alignment during the production process, ensuring precise matching between the materials of each layer, reducing quality problems caused by misalignment, reducing the possibility of rework, saving time and costs, and helping workers or automated equipment to assemble faster and more accurately, thereby improving production efficiency.
[0058] Specifically, the thickness of the portion where the elastic mesh 3 is bonded to the outer wing 1 and the portion where the elastic mesh 3 is bonded to the inner wing 2 is greater than the edge of the elastic mesh 3, and a smooth transition is performed in these areas.
[0059] Increasing the thickness in the bonding area distinguishes it from the edge area, facilitating the subsequent positioning of the outer wing 1, inner wing 2, and two layers of adhesive film 4. This enhances the support and structural stability of these key areas, especially in critical areas requiring more support, such as under or on the side of the breast. The smooth transition reduces abrupt changes caused by thickness variations, preventing material buildup or edge curling and improving wearing comfort.
[0060] Specifically, the width of the adhesive film 4 is less than or equal to the width of the outer wing 1, and the adhesive film 4 is provided with vent holes. The positions of the vent holes correspond one-to-one with the first mesh 303 and the second mesh 304 on the elastic net 3.
[0061] By setting corresponding mesh holes on the adhesive film 4, heat and pressure can be evenly distributed to each mesh area during hot pressing or ultrasonic welding, thereby enhancing the bonding strength of the overall structure. The mesh holes on the adhesive film 4 correspond one-to-one with the mesh holes on the elastic mesh 3, ensuring the consistency of the airflow path. The presence of the adhesive film 4 will not obstruct airflow, thus maintaining good breathability. Good breathability helps to expel moisture and increase airflow, improving the wearer's comfort.
[0062] Specifically, the shape of the vent hole is the same as that of the first mesh 303, but the size of the vent hole is slightly larger than that of the first mesh 303.
[0063] The vent holes are slightly larger than the first mesh 303, providing a larger airflow path and helping to improve the breathability of the entire structure. Because the vent holes are slightly larger, even if there is a slight positional deviation during the production process, it can ensure that the film 4 completely covers and protects the first mesh 303 of the elastic mesh 3, avoiding material accumulation or uneven thickness caused by misalignment, reducing rework or scrap rates caused by misalignment, and improving production efficiency.
[0064] Preferably, the outer dimensions of the vent holes are 0.2-1mm larger than the outer dimensions of the first mesh 303.
[0065] Specifically, the outer wing 1, the inner wing 2, the elastic mesh 3, and the two layers of adhesive film 4 are connected by hot pressing or ultrasonic welding technology.
[0066] Hot-press welding technology transfers heat to the surfaces of the materials to be joined and applies appropriate pressure, causing the materials to melt and fuse at the contact surface. After the heat source is removed, the materials are cooled and solidified under pressure to form a strong joint.
[0067] Ultrasonic welding technology uses high-frequency mechanical vibration, typically 20kHz to 40kHz, to generate frictional heat that heats the contact surfaces of the materials. Heat is generated only in the welding area, avoiding the influence on surrounding materials. After the vibration stops, the material cools and solidifies rapidly, forming a high-strength joint.
[0068] Both technologies ensure a tight bond between the layers of material, enhance the stability of the overall structure, and improve the durability and reliability of the product. Since there are no traditional sewing stitches, wearers can have a smoother, seamless fit and reduce discomfort caused by thread rubbing against the skin.
[0069] Specifically, it also includes several glue bones 5, which are set vertically along the side wings to enhance the support of the side wings.
[0070] The boning 5, positioned vertically along the side wings, helps to fix the side wing position and prevents slippage during wear, ensuring the bra stays in the correct position throughout the entire wearing process. The presence of the boning 5 also helps to distribute the pressure applied to the side wings, avoiding discomfort or skin damage caused by excessive local pressure.
[0071] This design enhances the support of the side wings, reduces friction caused by material movement or deformation, improves wearing comfort, and helps achieve a smoother, more seamless appearance.
[0072] Specifically, the glue 5 is in the shape of a narrow sheet, and its length is three-quarters of the width of the side wing. The thickness of the glue 5 is the same as the thickness of the elastic mesh 3.
[0073] The narrow, sheet-like bob 5 provides necessary support while reducing pressure points on the skin, avoiding discomfort caused by excessive contact. Its length, being three-quarters the width of the side wing, ensures that the bob 5 effectively covers key areas requiring additional support, such as the middle of the side wing, while allowing the edges to remain soft and flexible to adapt to different body types. This effectively increases the rigidity and stability of the side wing, preventing deformation or shifting during wear. The thickness of the bob 5 is the same as that of the elastic mesh 3, ensuring a smooth transition between the layers of material, reducing unevenness caused by thickness differences, improving the wearing experience, and guaranteeing a seamless appearance.
[0074] Specifically, the glue 5 is pre-embedded in the elastic mesh 3. The glue 5 is fixed inside the elastic mesh 3 by hot pressing or ultrasonic welding technology, thereby ensuring that the glue 5 is firmly fixed in the elastic mesh 3 while maintaining a smooth and seamless external effect.
[0075] By pre-embedding, the glue bone 5 can be precisely placed in key areas requiring additional support, such as the center of the side wing, ensuring optimal support and enhancing the overall strength and stability of the elastic mesh 3. Fixing the glue bone 5 using hot pressing or ultrasonic welding technology makes the entire side wing appear smoother and seamless, reducing unsightly marks that may result from traditional sewing stitches. The glue bone 5 has the same thickness as the elastic mesh 3, facilitating hot pressing or ultrasonic welding processes during manufacturing without requiring additional equipment or procedures, simplifying the production process. The standardized design reduces special customization needs, lowers production costs, and improves production efficiency.
[0076] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
