Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of underwear, and particularly relates to a chest-binding underwear with a composite ultra-thin elastic coaster. Background Art
[0002] With society's diverse understanding of female physical beauty and the growing demand for specific occupations and recreational activities, bra binders designed to adjust breast shape and enhance the wearer's physique have emerged. Historically, the concept of bra binders dates back to ancient times. At that time, constrained by social culture and clothing design, some women used techniques such as waist and chest binding to achieve specific dressing styles. For example, gender role switching in ancient drama performances required the use of bra binders to blur gender identity. In modern society, this traditional technique has been given new life, particularly in film and television productions, stage performances, and cosplay culture, where bra binders have become an indispensable tool for character creation. For example, in film and television, actresses playing male roles or needing to project a sophisticated, androgynous image often use bra binders to reduce the outline of their breasts and better fit the character's setting. Similarly, in cosplay activities, enthusiasts facing the challenge of effectively concealing or minimizing breast features when portraying male characters face the challenge of effectively concealing or reducing breast size. Therefore, bra binders have become a crucial aid in achieving character emulation.
[0003] However, traditional methods of chest binding often focus on the extreme compression effect, ignoring the comfort and health considerations of wearing. For example, in the prior art, Chinese patent No. CNCN202504192 discloses a corset, including a corset body made of a stretch fabric of the same material, and the corset body is a single-layer or double-layer structure. Although the above-mentioned corset has the function of evenly flattening the breasts, the corset body is only composed of a single or double layer of fabric. When some women with large breasts wear it, obvious bulges will appear, which makes the wearer embarrassed.
[0004] To address the nipple problem, some bras on the market incorporate a thin, flat, flat pad. However, this thinness results in poor anti-bulge effectiveness, and completely flat pads struggle to fit large breasts. Large-breasted women are prone to developing wavy deformations around their breasts when wearing them. Furthermore, because flat pads are made of fabric with all structures completely aligned on the same plane, deformation becomes more pronounced and difficult to fully recover from when subjected to external forces such as stretching and compression. Consequently, most flat pads experience structural instability, such as deformation and clumps, after washing, affecting subsequent wear. Addressing these issues through thickening can lead to poor breathability, and visible edge marks from the pads when worn. Separate, partial coasters, such as those shaped like rabbit ears, are also available on the market. These partial coasters only cover the nipple points, providing poor coverage of the entire breast area, resulting in a poor final bra binding effect.
[0005] Therefore, there is an urgent need for a bra with a composite ultra-thin elastic coaster that can achieve moderate compression of the chest while ensuring the comfort and health and safety of the wearer. Summary of the Invention
[0006] In response to the problems in the related art, the utility model proposes a bra binding bra with a composite ultra-thin elastic cup pad to overcome the above-mentioned technical problems existing in the existing related art.

[0014] In the present invention, the center thickness of the slightly convex small cup is preferably 0.50 cm, and the thickness of the flat large pad is preferably 0.08 cm.
[0015] Furthermore, the upper edge of the composite coaster is a downwardly concave arc curve, and the lower edge thereof is an upwardly convex arc curve, wherein the absolute value of the curvature of the upper edge is greater than the absolute value of the curvature of the lower edge.
[0016] Furthermore, the height of each of the slightly convex cups is in the range of 0.80-1.20 cm. In the present invention, the height of each of the slightly convex cups is preferably 1.00 cm.
[0017] Furthermore, the width of the lower edge of each of the slightly convex small cups from the lower edge of the composite coaster is smaller than the width of the upper edge of the slightly convex small cup from the upper edge of the composite coaster.
[0018] Furthermore, the low-elastic front placket includes a surface fabric layer, a composite coaster and a skin-contacting layer sequentially connected from the outside to the inside; wherein a coaster cavity for placing the composite coaster is formed between the surface fabric layer and the skin-contacting layer, and the coaster cavity defines the position of the composite coaster.

[0023] Beneficial effects of the utility model:
[0024] (1) First, the curvature design of the slightly convex small cup of the present invention can disperse external forces such as compression and stretching. Compared with flat fabrics, when a composite cup pad with a curved structure is subjected to the same external force, the curvature of the structure can disperse the external force to a certain extent. Therefore, the degree of deformation is relatively small and it is easier to restore to its original shape, which can better avoid deformation caused by washing or deformation caused by stretching when wearing. At the same time, the chest binder can better fit the shape of the female chest, improve the fit of the bra binder, and thus ensure a comfortable experience when wearing. Moreover, the flat large pad can evenly flatten the breasts, and the slightly convex small cup can effectively avoid oppression on the mastoid process, which truly achieves the goal of wrapping the chest while maintaining a flat chest state and preventing bulges.
[0025] (2) Secondly, the thickness of the slightly convex small cup decreases from the center to the edges until it is consistent with the thickness of the flat large pad. This design of natural thickness transition further enhances the comfort and natural feeling of the bra. At the same time, the thickness of the edges of the slightly convex small cup and the flat large pad is relatively small, so that the edge of the composite cup pad can achieve an ultra-thin effect, thereby increasing the breathability of the bra and reducing the pressure of the bra on the human chest. In addition, the composite cup pad includes the slightly convex small cup and the flat large pad, and the front placket can achieve full cup wrapping of both breasts, which has a stronger wrapping effect on the entire chest.
[0026] (3) Moreover, the multi-layer composite structure design of the low-elastic front placket and the composite coaster gives the bra-binding bra a super strong elastic control force, which can effectively prevent the coaster from being deformed due to a large breast, allowing the bra to always maintain a perfect fit and maintain a flat chest effect for a long time; for women with large breasts, the bra-binding bra can achieve the effect of making the breasts appear smaller.

[0037] like Figure 1-2 As shown, this embodiment provides a bra with a composite ultra-thin elastic coaster, comprising a bra body, the bra body comprising a low-elastic front flap 1 and a low-elastic back flap 2, the low-elastic back flap 2 comprising a shoulder strap 21; the shoulder portion 11 of the low-elastic front flap 1 passes over the shoulder and extends toward the back until it connects with the shoulder strap 21 at the back to form a wide shoulder strap 4, and the side edges of the low-elastic front flap 1 and the side edges of the low-elastic back flap 2 are connected to form a side strap 5;
[0038] In this embodiment, the wide shoulder strap 4 can extend from the front to the back, and the connection point falls on the back. This design is conducive to dispersing the pressure on the shoulders, reducing the marks and discomfort that may be caused by the thin shoulder straps of traditional bras. It is especially suitable for wearing for a long time or when doing fitness activities, and improves the comfort of the bra.
[0039] The low-elastic front placket 1 includes a chest corset 12, a cup pad cavity is provided in the chest corset 12, and a one-piece composite coaster 3 is provided in the coaster cavity; the composite coaster 3 is a multi-layer composite structure obtained by a composite pressurization process of multiple layers of breathable materials; the composite coaster 3 includes two left and right slightly convex small cups 31, and a flat large pad 32 connecting the two slightly convex small cups 31;
[0040] The coverage area of the slightly convex cups 31 is larger than the mastoid process of the breast but smaller than the breast; the edges of the two slightly convex cups 31 are completely surrounded by the flat pads 32, and the outer edges of the flat pads 32 are close to the outer edges of the breasts when worn, thereby making the wearer's protruding breasts appear more gentle, achieving a flat chest effect;
[0041] Each of the slightly convex cups 31 is slightly arched toward the outside of the wearer's body to wrap the breast process of the chest, and the edge of each slightly convex cup 31 transitions and extends toward the flat large pad 32; Figure 6 As shown, the thickness of each of the micro-convex cups 31 decreases from its center to the edges until it is consistent with the thickness of the flat pad 32;
[0042] First of all, the curvature design of the slightly convex small cup 31 can disperse external forces such as compression and stretching. Compared with flat fabrics, the composite coaster 3 with a curved structure can disperse the external force to a certain extent due to the structural curvature when subjected to the same external force. Therefore, the degree of deformation is relatively small and it is easier to restore to its original shape, which can better avoid deformation caused by cleaning or deformation caused by stretching when wearing. At the same time, it also enables the bra 12 to better fit the shape of the female chest, improves the fit of the bra underwear, and thus ensures a comfortable experience when wearing; moreover, the flat large pad 32 can evenly flatten the breasts, and the slightly convex small cup 31 can effectively avoid compression of the mastoid process, truly achieving the goal of wrapping the chest while maintaining a flat chest state, and preventing bulges.
[0043] Secondly, the thickness of the slightly convex small cup 31 decreases from the center to the edges until it is consistent with the thickness of the flat large pad 32. This design of natural thickness transition further enhances the comfort and natural feel of the bra. At the same time, the thickness of the edges of the slightly convex small cup 31 and the flat large pad 32 is relatively small, so that the edge of the composite coaster 3 can achieve an ultra-thin effect, so as to increase the breathability of the bra and reduce the pressure of the bra on the human chest. In addition, the composite coaster 3 includes the slightly convex small cup 31 and the flat large pad 32, and the front placket can achieve full cup wrapping of both breasts, which has a stronger wrapping effect on the entire chest.
[0044] Moreover, the multi-layer composite structure design of the low-elastic front placket 1 and the composite coaster 3 gives the bra-binding underwear super strong elastic control, which can effectively prevent the coaster from deforming due to large breasts, allowing the bra to always maintain a perfect fit and maintain a flat chest effect for a long time.
[0045] Specifically, the multi-layer composite structure includes a fabric layer, an inner cotton layer, a shaping layer, and a lining layer connected in sequence from the outside to the inside; wherein the fabric layer and the lining layer are both made of memory and stretch fabric, the inner cotton layer is made of fine and breathable sponge, and the shaping layer is made of round nipple mesh.
[0046] The provision of the circular nipple mesh enables the shaping layer to provide support to the multi-layer composite structure to a certain extent, helping to shape a slightly arched arc without causing excessive pressure on the chest.
[0047] Specifically, the low-elastic front placket 1 includes a surface fabric layer 16, a composite coaster 3 and a skin-contacting layer 17 connected in sequence from the outside to the inside;
[0048] More specifically, the face fabric layer 16 and the skin-contacting layer 17 are both integrally cut and formed from stretch-control fabrics;
[0049] It should be noted that the low-stretch front placket 1 utilizes a double-layered stretch-control fabric, combined with the composite coaster 3. This combination gives the bra a superior stretch-control. Whether for everyday wear or special occasions, it ensures even and strong support for the breasts. Even with a fuller bust, it effectively prevents the coaster from deforming due to larger breasts, ensuring a perfect fit and maintaining a long-lasting flat chest effect, providing a better wearing experience for anyone seeking comfort and a flatter chest.
[0050] A coaster cavity for placing the composite coaster 3 is formed between the surface fabric layer 16 and the skin-contacting layer 17, and the coaster cavity defines the position of the composite coaster 3;
[0051] like Figure 4As shown, one side of the composite coaster 3 is connected to the skin-contacting layer 17 via an annular adhesive dot structure 6, and the other side is not connected to the surface fabric layer 16; the annular adhesive dot structure 6 includes multiple layers of rings of different sizes, and the multiple layers of rings extend along the edge of the composite coaster 3;
[0052] In this embodiment, the surround composite coaster 3 adopts advanced glue-dot reinforcement technology. This innovative process greatly enhances the structural stability of the underwear. Even when worn for a long time or in an active state, it can ensure that the shape of the underwear remains stable and is not easily deformed or shifted when worn or washed.
[0053] like Figure 5 As shown, the cup width of the composite coaster 3 is in the range of 28.00-31.00 cm; the cup height of the composite coaster 3 is in the range of 12.50-15.50 cm; and the diameter of the slightly convex cup 31 is in the range of 8.50-13.50 cm.
[0054] like Figure 6 As shown, the thickness of the composite coaster 3 ranges from 0.06 to 0.52 cm, wherein the center thickness of the slightly convex cup 31 ranges from 0.48 to 0.52 cm, and the thickness of the flat large pad 32 ranges from 0.06 to 0.10 cm;
[0055] In this embodiment, the center thickness of the micro-convex cup 31 is preferably 0.50 cm, and the thickness of the flat large pad 32 is preferably 0.08 cm;
[0056] More specifically, the height of each of the micro-convex cups 31 is in the range of 0.80-1.20 cm. In this embodiment, the height of each of the micro-convex cups 31 is preferably 1.00 cm.
[0057] In this embodiment, the overall thickness of the bra is controlled within an ultra-thin range (0.06-0.52 cm). This ultra-thin design not only reduces the weight of the bra, but also significantly improves wearing comfort and breathability, making it almost invisible to the wearer during daily activities. Furthermore, the ultra-thin edge design cleverly conceals the bra under clothing, leaving no visible edge trace even when wearing tight clothing. Furthermore, the slightly convex cup 31 has the largest thickness at its center, primarily to prevent bulges and avoid embarrassment.
[0058] Furthermore, most breasts are not flat; rather, they have curves. In the composite cup pad 3 described in this embodiment, different areas have varying thicknesses. This thickness distribution, combined with the height of the slightly convex cups 31, not only ensures adequate support and coverage of the breasts, but also helps shape the slightly arched shape through moderate compression, allowing the bra to more closely conform to the curves of the breasts. Furthermore, the thinner flat pad 32 reduces pressure on areas of the breast other than the breasts, making the bra more comfortable and natural to wear.
[0059] like Figure 5 As shown, the upper edge of the composite coaster 3 is a downwardly concave arc curve, and the lower edge is an upwardly convex arc curve, wherein the absolute value of the curvature of the upper edge is greater than the absolute value of the curvature of the lower edge to adapt to the curve of the human chest;
[0060] It should be noted that there is a cleavage line between the two breasts of the human body, and the lower edges of the two breasts are also curved. The design of the upper and lower edges of the composite coaster 3 with curved curves fully takes into account the natural curve of the human chest, so that the composite coaster 3 fits the chest better, avoids the gaps caused by the traditional coaster being too flat, and avoids the obvious coaster edge marks when wearing a bra, thereby achieving a natural flat chest effect.
[0061] Specifically, the width of the lower edge of each of the slightly convex cups 31 from the lower edge of the composite coaster 3 is smaller than the width of the upper edge of the slightly convex cup 31 from the upper edge of the composite coaster 3;
[0062] It should be noted that due to the effect of gravity, the human breast will sag, so each of the slightly convex cups 31 is arranged closer to the lower edge of the composite coaster 3, so that each of the slightly convex cups 31 can wrap more breast fat, and further ensure that each of the slightly convex cups 31 can completely cover the nipple point to prevent bulging.
[0063] like Figure 3 As shown, the length of the side ratio 5 ranges from 16.00 to 20.00 cm, and the upper end of the side ratio 5 extends upward to form a raised curved portion 51 that wraps around the accessory breast;
[0064] The length of the side ratio 5 varies with the size of the underwear. The underwear sizes from small to large include S, M, L, XL, and XXL. Compared with the prior art, the extended length of the raised bending portion 51 of different underwear sizes in this embodiment ranges from 1.50 to 1.80 cm. In this embodiment, taking size S as an example:
[0065] The side length of the S size bra is about 16.30 cm, while the side length of the S size bra in the prior art is about 14.80 cm. Therefore, compared with the prior art, the raised bending portion 51 of the bra in this embodiment is raised by 1.5 cm.
[0066] The design of the raised curved portion 51 not only enhances the support of the bra on the side of the human body, but also enables the raised curved portion 51 to wrap the accessory breasts, preventing fat from overflowing from the side of the body, and is more helpful in shaping and maintaining a beautiful body shape.
[0067] Specifically, the low-elastic back flap 2 is a single-layer structure, thereby enhancing breathability and reducing pressure on the back.
[0068] The low-elastic front placket 1 includes a front collar 13, and the shape of the front collar 13 includes U-shape, square shape, V-shape or circle;
[0069] In this embodiment, the shape of the front collar 13 is not limited and can be designed according to actual wearing requirements. For example, S- and M-sized bras use a square front collar 13, while L-, XL-, and XXL-sized bras use a U-shaped front collar 13.
[0070] like Figure 1 As shown, the low-elastic front placket 1 is provided with a lower pick 14 below the chest corset 12, and the lower pick 14 can be used to set a logo; Figure 2-3 As shown, the bottom of the low-elastic front flap 1 is fitted with the shawl to form the front perimeter 15, and the bottom of the low-elastic back flap 2 is fitted with the shawl to form the back perimeter 22. The lower edge of the front perimeter 15 exceeds the lower edge of the back perimeter 22 to solve the problem of the warping of the lower perimeter of existing underwear.
[0071] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and any modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience of description only and do not constitute any limitation to the present invention.
