Description

Technical Field

[0001] The utility model relates to the technical field of bra underwear products, in particular to a bra with a built-in lining. Background Art

[0002] Currently, in order to further improve the structure of bra cups and achieve better wearing experience, bras with built-in flexible pockets have appeared on the market. However, the production process of such cups with built-in flexible pockets is relatively complex, and the requirements for the flexible pockets (bags with different filling materials such as water bags, oil bags, air bags, powder bags, and silica gel bags) are also very high.

[0003] The existing production process for bra cups with built-in flexible pouches typically involves first molding the outer sponge once or twice, then the inner sponge once or twice, then adding the flexible pouch and molding it once more. This requires a total of three to five molding cycles, and the built-in flexible pouch must be resistant to high temperatures and high pressures. However, after multiple molding cycles, the sponge becomes hard, affecting wearer comfort. Furthermore, multiple molding cycles can lead to inaccurate alignment and inconsistent molding quality, reducing product yield and increasing production costs.

[0004] Moreover, common built-in liner bras have many problems. For example, if the external force of lifting and pushing is insufficient, the female breasts may sag naturally and quickly due to lack of external protection, and the function of modifying the breasts may be lost. The movable built-in liner is prone to displacement, affecting the plastic surgery effect. For movable water bag pads, attention should be paid to the matching of the upper part of the bra with the water bag design to avoid the water in the water bag from concentrating under the bra, which would create an uncoordinated and abrupt feeling between the upper and lower cups of the bra.

[0005] Publication No. CN204697917U discloses a bra cup with a built-in lining, comprising a cup body comprising an inner sponge layer and an outer sponge layer, a receiving space defined between the inner and outer sponges, and a flexible lining disposed within the receiving space. However, during production and processing, the built-in lining of this patent suffers from a problem in that the dimensions of the built-in lining and the receiving space do not fully match. Generally, the dimensions of the built-in lining are smaller than the receiving space, causing the built-in lining to easily shift during use. This makes it difficult to maintain a fixed relative position between the built-in lining and the cup, thus affecting the bra's shaping effect.

[0006] Publication number CN204292221U discloses a novel memory foam bra pad, comprising a bra shell and straps. The bra shell houses a built-in memory foam pad with a thin edge, and the bra shell is sewn to the bra shell via the thin edge. This invention utilizes a thin edge structure, which secures the pad to the bra cup via the thin edge, making it less likely to shift. However, the thin edge surrounding the memory foam pad is sewn to the bra cup, requiring additional sewing steps. Furthermore, the relative position of the memory foam pad and the bra cup is difficult to control, resulting in inconsistent movement of the solid foam and breasts, making it difficult to create a more natural cleavage effect.

[0007] Therefore, existing bras with built-in linings have the problem that the built-in lining is easily offset and the relative position of the built-in lining and the cup is difficult to control, resulting in poor shaping effect.

[0008] At the same time, consumers are also concerned that bras that use flexible bags as linings may break in the event of collision or pressure. Summary of the Invention

[0009] In view of this, the present invention aims to propose a bra with a built-in lining to solve the problems in existing bra products that the built-in lining is prone to displacement and the relative position of the built-in lining and the cup is difficult to control, resulting in poor shaping effect.

[0010] The built-in liner of a bra in use often shifts. The reason is due to the use requirements and material characteristics of the bra. The containing cavity is formed by the inner and outer layers of sponge, which has good elasticity. The containing space is prone to deformation during use, such as uneven force caused by improper wearing and the cumulative effect of unbalanced movements in daily wear. The built-in liner is flexible. If it is not fixed in the containing space, the built-in liner will be displaced relative to the containing space, causing the built-in liner to shift. At the same time, if the wearer engages in strenuous exercise, the relative displacement between the built-in liner and the containing space is more significant. In particular, the built-in liner is more prone to shifting because the wearer's center of gravity changes significantly more than the containing space, thereby affecting the shaping effect.

[0011] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0012] A bra with a built-in lining comprises a cup body, wherein the cup body comprises an outer sponge layer and an inner sponge layer, an accommodating space is provided between the outer sponge layer and the inner sponge layer, and a flexible lining body is provided in the accommodating space.

[0013] An extension portion is provided at the lower portion of the flexible lining, and the extension portion is fixed between the lower edges of the outer sponge and the inner sponge;

[0014] A groove is provided on the lower edge of the outer sponge or the inner sponge, and the groove is used to place the extension part.

[0015] Furthermore, the length, width and height of the extension portion are l×w×h respectively, and the length, width and depth of the groove are L×W×H respectively, where L=l, W≥w, and H≤h.

[0016] Furthermore, the flexible liner includes a liner bag and a medium, the medium is sealed and filled in the liner bag, and the liner bag and the extension portion are integrally formed or spliced ​​together.

[0017] Furthermore, the medium can flow in the liner bag.

[0018] Furthermore, a bonding portion is provided on the lower half of the flexible lining to limit the medium in the flexible lining from concentrating below the cup body.

[0019] Furthermore, the bonding portion is formed by bonding two surfaces of the liner bag, and the cross-section of the bonding portion is circular, elliptical or polygonal.

[0020] Furthermore, a plurality of bonding portions are provided, so that the thickness of the lower half of the flexible lining is smaller than that of the upper half.

[0021] Furthermore, the bonding strength of the bonding portion is smaller than the bonding strength of the edge of the flexible lining.

[0022] Furthermore, the outer sponge, the extension portion and the inner sponge are connected and fixed by sewing, gluing or pressing.

[0023] Compared with the prior art, the bra with a built-in lining of the present invention has the following advantages:

[0024] 1. The utility model provides an extension part and a groove, and on the basis of the original production process, there is no need to add a production process, so as to achieve the fixation and quick installation of the flexible lining, which helps to improve production efficiency and product quality, avoid the displacement of the flexible lining during use, and meet the requirements of women for shaping effects.

[0025] 2. The utility model provides an adhesive part so that the thickness of the lower half of the flexible lining is smaller than that of the upper half, which can prevent the medium from accumulating downwards and ensure that the medium is more evenly distributed in the entire lining bag, making the appearance of the bra smoother and more natural. The bra fits the body curve more closely when worn, which helps to maintain a good shape and reduce the discomfort caused by uneven distribution of the medium. It can ensure that the medium inside the bra will not change significantly due to body movement, and at the same time avoid local pressure caused by local accumulation of the medium, thereby improving overall comfort, ensuring that the appearance of the bra has no abrupt bulges or depressions, improving the aesthetics, and further improving the overall product quality and user satisfaction.

[0026] 3. The utility model relates to a case where, when the medium is one or more combinations of water, oil or gas, the bonding strength of the bonding part is less than the bonding strength of the edge of the flexible lining. After the flexible lining is subjected to collision pressure, the bonding part swells and separates before the edge of the lining bag. The internal space of the lining bag increases, absorbing and buffering the pressure generated by the collision, so that the flexible lining can withstand greater pressure, preventing the leakage of the medium caused by the rupture of the flexible lining, affecting the continued use of the bra, and avoiding embarrassment to the wearer when similar situations occur in public places, affecting the wearer's use of such bra products.

In this specification, the illustrative use of the above terms does 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 any one or more embodiments or examples.

[0042] The utility model discloses a bra with a built-in lining, comprising a cup body 1, the cup body 1 comprising an outer sponge 2 and an inner sponge 3, an accommodating space 5 being provided between the outer sponge 2 and the inner sponge 3, and a flexible lining 4 being provided in the accommodating space 5;

[0043] An extension portion 6 is provided at the lower portion of the flexible lining 4 , and the extension portion 6 is fixed between the lower edges of the outer sponge 2 and the inner sponge 3 ;

[0044] A groove 7 is provided on the lower edge of the outer sponge 2 or the inner sponge 3 , and the groove 7 is used to place the extension part 6 .

[0045] The flexible lining 4 is provided with an extension part 6, which is fixed between the lower edges of the outer sponge 2 and the inner sponge 3, and can help fix the flexible lining 4 to prevent the flexible lining 4 from moving during wearing and affecting the shaping effect of the bra.

[0046] During production and processing, after the outer sponge 2 and the inner sponge 3 are molded, the flexible lining 4 is placed in the accommodating space 5, and the extension part 6 is placed in the groove 7, so as to realize the rapid installation of the flexible lining 4 and ensure that the relative position of the flexible lining 4 and the cup body 1 is stable.

[0047] After the flexible lining 4 is installed, the outer sponge 2, the extension 6 and the inner sponge 3 are connected and fixed by sewing, gluing, pressing and other common industry technologies. There is no need to add sewing, gluing or pressing steps, and the flexible lining 4 can be fixed according to the original production process.

[0048] This bra with a built-in flexible lining 4, based on the original production process, can achieve the fixation and quick installation of the flexible lining by providing an extension part 6 and a groove 7 without adding any production process, thereby avoiding the displacement of the flexible lining 4 during use, helping to improve production efficiency and product quality, and meeting women's requirements for shaping effects.

[0049] Preferably, the groove 7 is provided at the lower edge of the outer sponge 2 .

[0050] When using a molding machine to mold the outer sponge 2 and the inner sponge 3 respectively, the groove 7 is set on the side of the lower edge of the outer sponge 2 adjacent to the wearer to avoid the sponge feeling corresponding to the groove 7 becoming hard after the inner sponge 3 is molded, which affects the wearing comfort. At the same time, the extension part 6 is fixed between the outer sponge 2 and the inner sponge 3 after installation, which increases the thickness and rigidity of the lower edge of the cup body 1, helps to ensure the shape of the bra, and effectively improves the supporting capacity of the lower edge of the cup body 1.

[0051] This arrangement can effectively improve the supporting capacity of the lower edge of the cup body 1, achieve a better shaping effect, and ensure wearing comfort.

[0052] Specifically, the length, width and height of the extension portion 6 are respectively l×w×h, and the length, width and depth of the groove 7 are respectively L×W×H, where L=l, W≥w, and H≤h.

[0053] The extension part 6 and the groove 7 are precisely matched to ensure that the extension part 6 is firmly placed in the groove 7 and will not become loose or unable to be placed due to length differences. The width w of the extension part 6 is smaller than the width W of the groove 7, so that the extension part 6 does not extend outside the cup body 1, making the bra appearance more beautiful. The height h of the extension part 6 is smaller than the depth H of the groove 7, avoiding excessive deformation of the groove 7.

[0054] This arrangement allows the extension portion 6 to precisely match the groove 7, and the extension portion 6 completely covers the outer sponge 2, which helps to improve the overall appearance of the bra and ensure the shaping effect.

[0055] Specifically, the flexible liner 4 includes a liner bag 8 and a medium 9 . The medium 9 is sealed and filled in the liner bag 8 . The liner bag 8 and the extension portion 6 are integrally formed or spliced ​​together.

[0056] The liner bag 8 serves as a container for the medium 9 to protect the medium 9 from the external environment. Filling the liner bag 8 with the medium 9 can provide additional support or shaping functions.

[0057] The integral molding of the liner bag 8 and the extension part 6 makes the processing of the flexible liner 4 faster and more convenient, reduces the processing steps, and has a stronger structure, reduces the possibility of failure at the connection, and improves the overall durability; the liner bag 8 and the extension part 6 are combined together by splicing, which is convenient for replacing the extension part 6 of different materials and adjusting the structural strength of the extension part 6 after being connected with the outer sponge 2 and the inner sponge 3, thereby ensuring wearing comfort.

[0058] This setting can adjust the hardness or softness by replacing the medium 9 as needed, thereby improving the versatility of the product to adapt to different wearing needs, extending the service life of the bra, ensuring a smoother and more natural appearance, and making the bra more visually attractive.

[0059] Specifically, the medium 9 can flow in the liner bag 8 .

[0060] The arrangement allows the medium 9 to flow in the liner bag 8, so that the medium 9 has a greater degree of freedom, and the flexible liner 4 has a larger adjustment range, which is suitable for a wider range of people and has a better shaping effect.

[0061] Specifically, the liner bag 8 is made of TPU film or PVC film, the medium 9 is one or more filling materials such as water, oil, gas, powder, etc., and the extension part 6 is made of TPU film, PVC film or cloth.

[0062] TPU film has good elasticity and wear resistance, and is suitable for applications that require repeated bending and stretching. TPU film is cold-resistant, oil-resistant, hydrolysis-resistant, and UV-resistant, and has excellent physical and mechanical properties and chemical resistance. It is suitable for making liner bags that need to maintain their shape for a long time; PVC film has low cost, good flexibility and waterproof properties, PVC film is easy to process and shape, suitable for large-scale production, and relatively cheap; the fabric can provide a soft and comfortable touch, suitable for areas that directly contact the skin, and has good breathability, moisture absorption and perspiration, suitable for long-term wear.

[0063] The medium 9 is selected according to needs, so that the bra can have multiple functions and increase the scope of application. For example, water has good fluidity and can automatically adjust its shape according to the body's contours and movements; oil is thicker than water and can provide more stable support and reduce shaking.

[0064] This arrangement can provide liner bags 8, media 9 and extension parts 6 made of different materials according to individual needs, provide different levels of manufacturing, achieve different wearing experiences, and improve comfort and durability.

[0065] Specifically, the lower half of the flexible lining 4 is provided with an adhesive portion 10 for limiting the medium in the flexible lining 4 from being concentrated below the cup body 1 .

[0066] The setting of the adhesive part 10 can prevent the medium 9 from piling up downwards, ensure that the medium 9 is more evenly distributed in the entire liner bag 8, ensure that the bra provides consistent support in different parts, avoid local hardness or softness, make the bra's appearance smoother and more natural, and help maintain a good shape.

[0067] This setting allows the bra to fit the body curves better when worn, reduces discomfort caused by uneven distribution of the medium, ensures that the medium inside the bra does not change significantly due to body movement, provides continuous support, and avoids local pressure caused by local accumulation of the medium, thereby improving overall comfort, ensuring that the appearance of the bra has no abrupt bulges or depressions, improving aesthetics, and further improving the overall product quality and user satisfaction.

[0068] Specifically, the bonding portion 10 is formed by bonding two surfaces of the liner bag 8 , and the cross section of the bonding portion 10 is circular, elliptical, or polygonal.

[0069] The bonding portion 10 is formed by bonding the two surfaces of the liner bag 8, which reduces the accommodation space in the lower half of the liner bag 8 while ensuring the flexibility and elasticity of the liner bag 8, and can ensure that the medium is evenly distributed in the liner bag 8, avoiding the medium from concentrating downward under the action of gravity, affecting the shaping effect; the cross-section of the bonding portion 10 is circular, elliptical or polygonal, so that it can adapt to the production material preparation of different manufacturers and improve the scope of application.

[0070] The bonding portion 10 has a simple structure, a simple and quick processing method, and a low production cost.

[0071] Specifically, a plurality of bonding portions 10 are provided, so that the thickness of the lower half of the flexible lining 4 is smaller than that of the upper half.

[0072] By providing multiple adhesive parts 10 in the lower half, the medium can be distributed more in the upper half, better fitting the chest curve, providing uniform support, reducing the shaking of the chest, making the shape of the bra smoother and more natural, ensuring that the appearance of the bra is more beautiful, without abrupt bulges or depressions, and achieving a better shaping effect.

[0073] This setting allows the bra to fit the body curves better when worn, reduces discomfort caused by the concentration of media in the lower part, ensures that the bra does not change significantly due to body movement, provides continuous support and improves comfort.

[0074] Specifically, when the medium 9 is one or more combinations of water, oil, or gas, the bonding strength of the bonding portion 10 is smaller than the bonding strength of the edge of the flexible lining 4 .

[0075] When the medium 9 is one or more combinations of water, oil, or gas, existing built-in liner bras are prone to rupture of the flexible liner 4 when subjected to collision pressure, causing leakage of the medium 9, staining clothing, and affecting the continued use of the bra. Furthermore, similar situations in public places can easily cause embarrassment to the wearer, affecting the wearer's use of such bra products. After the flexible liner 4 is subjected to collision pressure, the medium 9 is compressed and acts on the liner bag 8. This force acts on the edge of the liner bag 8 and the adhesive portion 10 simultaneously. Since the adhesive strength of the adhesive portion 10 is less than the adhesive strength of the edge of the flexible liner 4, the adhesive portion 10 ruptures and separates before the edge of the liner bag 8. The internal space of the liner bag 8 increases, absorbing and buffering the pressure generated by the collision, allowing the flexible liner 4 to withstand greater pressure and avoid rupture of the flexible liner 4.

[0076] This setting can absorb and buffer the pressure generated by collision, reduce the impact of the medium 9 on the edge of the liner bag 8, improve the pressure-bearing capacity of the liner bag 8, prevent the flexible liner 4 from rupturing and causing leakage of the medium 9, affecting the continued use of the bra, and avoid similar situations in public places that may cause embarrassment to the wearer and affect the wearer's use of such bra products.

[0077] Specifically, the outer sponge 2, the extension portion 6 and the inner sponge 3 are connected and fixed by sewing, gluing, pressing and other common industry techniques.

[0078] This setting can be selected according to specific needs to ensure that the connection parts will not cause irritation or discomfort to the skin, and can ensure that the connection between the outer sponge 2, the extension part 6 and the inner sponge 3 is strong enough to extend the service life of the bra. According to different materials and design requirements, the most suitable connection method can be selected to ensure a firm connection while taking into account the comfort, aesthetics and durability of the bra.

[0079] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
