Technical Field

[0001] The present application relates to the technical field of underwear, and in particular to a cup and a bra. Background Art

[0002] Most of a woman's breasts are made of fat tissue, with some ligaments and skin providing internal support, but these supports are sometimes not enough to support the breasts, which can easily cause breast pain and discomfort in daily life. Bras are underwear, mainly used to support and protect the wearer's breasts. Bras are usually composed of two cups, a bottom strap, and shoulder straps.

[0003] When making padded bra cups, some practices are to place fillers between two pieces of fabric and base material with the same length and width, completely overlap the outer edges of the fabric and base material, and sew the overlapped outer edges to fix them. This practice makes the entire outer edge stiff and affects breathability, thereby affecting the user's wearing comfort. Utility Model Content

[0004] The main purpose of this application is to provide a cup and a bra, aiming to solve the technical problem that the outer edges of the fabric and the base material in the bra cup are completely overlapped, causing the outer edges to be stiff and affecting the breathability.

[0005] To achieve the above objectives, the present application proposes a cup, comprising:

[0006] An outer coating layer, wherein the outer coating layer has an arc-shaped concave surface;

[0007] A filling layer is installed on the outer covering layer and is located on the arc-shaped concave surface.

[0008] Optionally, the cup further comprises:

[0009] The inner covering layer is located on the arc-shaped concave surface, and the outer edge of the inner covering layer is connected to the outer covering layer; the outer edge of the inner covering layer partially overlaps with the outer edge of the outer covering layer, and the filling layer is located between the inner covering layer and the outer covering layer.

[0010] Optionally, the inner coating layer is a single-layer structure or a multi-layer structure.

[0011] Optionally, the filling layer is located at any one or more of the bottom end, the top end, and the side end of the arc-shaped concave surface.

[0012] Optionally, the cup further comprises:

[0013] A cushion layer is located between the filling layer and the outer covering layer; the outer edge of the filling layer does not exceed the outer edge of the cushion layer.

[0014] Optionally, the outer covering layer and the cushion layer, the cushion layer and the filling layer, and the filling layer and the inner covering layer are all bonded by hot melt adhesive.

[0015] Optionally, the outer covering layer and the filling layer as well as the filling layer and the inner covering layer are bonded by hot melt adhesive.

[0016] Optionally, the filling layer is one of the following:

[0017] Polyurethane foam, air bags, oil bags, sandwich foam, silicone products, petroleum fiber fabrics, thermoplastic plastics.

[0018] Optionally, the cup comprises one or more filling layers.

[0019] Another technical solution proposed in the present application is as follows: a bra comprising the cup as described above.

[0020] Compared with the prior art, the present application discloses a cup and a bra, wherein the cup has an outer covering layer and a filling layer, wherein the filling layer is installed on one side of the outer covering layer located on the arc-shaped concave surface. Compared with a bra cup formed by overlapping a fabric and a base material, the cup provided by the present application omits the base material. Since the filling layer is only distributed in a position that requires support, the thickness of the outer edge of the cup is reduced, thereby avoiding causing the outer edge to become stiff, thereby improving breathability.

[0021] Moreover, the thin outer edge of the cup helps the wearer to achieve a seamless feeling and improves wearing comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] The present application aims to solve the technical problem that the outer edges of the fabric and the base material of the existing bra cup are completely overlapped, resulting in the outer edge being stiff and affecting the breathability. A cup and a bra are provided. The cup has an outer covering layer and a filling layer. The filling layer is installed on one side of the outer covering layer located on the arc-shaped concave surface. Compared with the bra cup formed by overlapping the fabric and the base material, the cup provided by the present application omits the base material. Since the filling layer is only distributed in the part that needs support, the thickness of the outer edge of the cup is reduced, avoiding the outer edge from being stiff, thereby improving the breathability. For details, please refer to the following embodiments.

[0036] Please refer to Figure 1 and Figure 2 In the first embodiment of the present application, a cup 10 is provided, comprising an outer covering layer 11 and a filling layer 12; the outer covering layer 11 has an arc-shaped concave surface 111; the filling layer 12 is installed on the outer covering layer 11 and is located on the arc-shaped concave surface 111.

[0037] It can be understood that the outer edge of the cup refers to the edge of the entire cup. Generally, for a cup made of fabric and base material, the sewn part is the outer edge of the cup, that is, the outer edge of the cup is stacked together by the fabric, base material and stitching, so that the outer edge of the cup is thicker, causing the outer edge of the cup to be stiff, affecting the breathability; the cup 10 provided in the present application is used in a bra and is wrapped around the wearer's breast when worn. The cup 10 has an outer covering layer 11 and a filling layer 12; the outer covering layer 11 forms an arc-shaped concave surface 111, and when the user wears it, the arc-shaped concave surface 111 is used to accommodate the wearer's breast; the filling layer 12 is located in the arc-shaped concave surface 111, and the thickness and size of the filling layer 12 correspond to the shape of the wearer's breast. The cup 10 provided in the present application omits the base material, and is only composed of the outer covering layer 11 and the filling layer 12. The filling layer 12 is installed on one side of the outer covering layer 11 located on the arc-shaped concave surface 111. The filling layer 12 is only distributed in the part that needs support, which is conducive to reducing the thickness of the outer edge of the cup 10, avoiding the outer edge from becoming stiff, thereby improving the breathability, and improving the comfort of the wearer, especially when wearing short-sleeved casual clothes. The thin outer edge of the cup 10 is conducive to making the wearer feel seamless and improving the wearing experience. The cup 10 in the present application is discussed as an individual separated from the bra. In actual use, the cup 10 will be connected to structures such as the bottom strap and shoulder straps.

[0038] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the cup 10 includes an outer covering layer 11, a filling layer 12 and an inner covering layer 13; the outer covering layer 11 has an arc-shaped concave surface 111; the filling layer 12 is installed on the outer covering layer 11 and is located on the arc-shaped concave surface 111; the inner covering layer 13 is located on the arc-shaped concave surface 111, and the outer edge of the inner covering layer 13 is connected to the outer covering layer 11; the outer edge of the inner covering layer 13 partially overlaps with the outer edge of the outer covering layer 11, and the filling layer 12 is located between the inner covering layer 13 and the outer covering layer 11.

[0039] It can be understood that the cup 10 provided by the present application is applied to a bra and covers the breast of the wearer when worn. The cup 10 comprises an outer covering layer 11, a filling layer 12 and an inner covering layer 13 which are arranged in sequence from the outside to the inside; the outer covering layer 11 forms an arc-shaped concave surface 111, and when the user wears and uses the cup, the arc-shaped concave surface 111 is used to accommodate the breast of the wearer; the filling layer 12 is located in the arc-shaped concave surface 111, and the thickness of the filling layer 12 is designed to correspond to the shape of the wearer's breast to fill the gap between the outer covering layer 11 and the wearer's breast, and has a wear-resistant function. The outer edge of the inner covering layer 13 is connected to the outer covering layer 11, so that the inner covering layer 13 and the outer covering layer 11 completely cover the filling layer 12, which has the function of fixing and protecting the filling layer 12, reducing wear and tear, and is conducive to maintaining the shape of the filling layer 12, thereby improving the durability of the cup 10 and extending the service life; the outer edge of the inner covering layer 13 is connected to the arc-shaped concave surface 111, and the connection method can be direct connection, for example: the outer edge of the inner covering layer 13 is fixed on the arc-shaped concave surface 111 1, or it may be indirectly connected, for example, by connecting through an intermediate connecting layer, which may be an adhesive layer, etc.; the outer edge of the inner covering layer 13 partially overlaps with the outer edge of the outer covering layer 11, which is explained in terms of size, that is, the outer edge size of the inner covering layer 13 is smaller than the outer edge size of the outer covering layer 11, so that after the inner covering layer 13 is installed on the outer covering layer 11, only part of the outer edge of the inner covering layer 13 can overlap with the outer edge of the outer covering layer 11, so that the outer covering layer 11 covers the inner covering layer 13. In this case, for the overlap, The thickness of the part that does not overlap is larger than that of the part that does not overlap; for the part that does not overlap, the outer edge of the cup 10 only has the outer covering layer 11, which is relatively thin, which is beneficial to reducing the thickness of the outer edge of the cup 10, avoiding the outer edge from becoming stiff, and having good air permeability; the shape of the inner covering layer 13 can be designed according to the shape of the filling layer 12, and is slightly wider than the filling layer 12 to form a just coverage of the filling layer 12 without causing material waste, and cooperates with the outer covering layer 11 to achieve hiding of the filling layer 12, preventing the material of the filling layer 12 from changing color and being exposed to the outside after long-term use, thereby affecting the appearance. The outer edges of the existing two layers of material overlap, making the outer edge of the cup 10 too thick, which not only increases the difficulty in sewing, but also makes the finished bra after sewing feel bulky to the wearer, increasing the sense of restraint and affecting the wearing experience. The present application avoids overlapping the outer edges of the inner covering layer 13 and the outer covering layer 11, reduces the thickness of the outer edge of the cup 10, and is conducive to improving the comfort of the wearer, especially when wearing short-sleeved casual clothes. The thin outer edge of the cup 10 is conducive to making the wearer feel seamless, and enhances the breathability and improves the wearing experience. The outer covering layer 11 and the inner covering layer 13 can be made of fabric, sandwich fabric or foam, and can be made of 100% polyester fabric.In addition, the outer edge of the inner covering layer 13 can also be arranged to completely overlap with the outer edge of the outer covering layer 11, that is, the outer edge size of the inner covering layer 13 is equal to the outer edge size of the outer covering layer 11, and the inner covering layer 13 and the outer covering layer 11 are bonded by hot melt adhesive. Compared with sewing fixation, it is beneficial to reduce the outer edge thickness of the cup 10, avoid causing the outer edge to be stiff, and facilitate ventilation.

[0040] In some embodiments, the inner coating layer 13 is a single-layer structure or a multi-layer structure.

[0041] It can be understood that the inner covering layer 13 is a single-layer structure or a multi-layer structure. Specifically, the inner covering layer 13 can be formed by stacking a single-layer material or a multi-layer material, which is determined specifically according to the material properties. The material can be fabric, sandwich fabric or foam, etc., or 100% polyester fabric. For example: the inner covering layer 13 is only a layer of polyester fabric, or the inner covering layer 13 is formed by stacking two layers of polyester fabric and a layer of foam, and the foam is located between the two layers of polyester fabric.

[0042] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the filling layer 12 is located at any one or more of the bottom, top, and side ends of the arc-shaped concave surface 111 .

[0043] It can be understood that the thickness of the filling layer 12 is designed to correspond to the shape of the wearer's breast to fill the gap between the outer covering layer 11 and the wearer's breast. The filling layer 12 can be specifically located at any of the bottom end, top end, and side end of the arc-shaped concave surface 111 of the outer covering layer 11. Specifically, the filling layer 12 is located at the bottom end of the arc-shaped concave surface 111, and the bottom end of the arc-shaped concave surface 111 corresponds to the lower side of the breast. The filling layer 12 provides support on the lower side of the breast; the filling layer 12 is located at the top end of the arc-shaped concave surface 111, and the top end of the arc-shaped concave surface 111 corresponds to the upper side of the breast. The filling layer 12 fills the gap between the breast and the outer covering layer 11 on the upper side of the breast, and plays a protective role on the upper side of the breast; the filling layer 12 Located at the side end of the arc-shaped concave surface 111, the side end of the arc-shaped concave surface 111 corresponds to the two sides of the breast. For example, a filling layer 12 is arranged on the side of the breast close to the arm bend to play a supporting effect; the filling layer 12 can also be distributed in multiple places in the bottom end, top end, and side end of the arc-shaped concave surface 111 of the outer covering layer 11. Specifically, the filling layer 12 is distributed at the bottom end and top end of the arc-shaped concave surface 111, the filling layer 12 is distributed at the bottom end and side end of the arc-shaped concave surface 111, the filling layer 12 is distributed at the top end and side end of the arc-shaped concave surface 111, or the filling layer 12 is distributed at the bottom end, top end, and top end of the arc-shaped concave surface 111, so that the filling layer 12 supports and protects the area around the nipple, thereby improving the comfort of the wearer.

[0044] In some embodiments, the filling layer 12 is one of the following: polyurethane foam, air bag, oil bag, sandwich cotton layer, silicone product, petroleum fiber fabric, thermoplastic plastic.

[0045] It is understood that any of polyurethane foam, air bags, oil bags, sandwich cotton layers, silicone products, polyester fiber and other petroleum fiber fabrics, and thermoplastic plastics can be used as the filling layer 12 between the wearer's breast and the outer covering layer 11, and multiple combinations can also be used as the filling layer 12 between the wearer's breast and the outer covering layer 11, for example: the filling layer 12 is composed of polyurethane foam and the outer petroleum fiber fabric; the filling layer 12 can also include a bra support ring (such as a steel ring, a rubber ring and / or a fabric ring, etc.) to achieve the support and protection of the cup 10 on the wearer's breast. The thickness of the filling layer 12 can be 2mm-50mm.

[0046] In some embodiments, the outer edge size of the filling layer 12 is smaller than the outer edge size of the inner coating layer 13 .

[0047] It can be understood that by setting the outer edge size of the filling layer 12 to be smaller than the outer edge size of the inner covering layer 13, the inner covering layer 13 completely covers the filling layer 12, preventing the outer edge of the filling layer 12 from leaking out and affecting the overall aesthetic effect of the cup 10. In particular, when the filling layer 12 is made of polyurethane foam, the polyurethane foam gradually turns yellow over time, and the exposure of the polyurethane foam affects the aesthetic effect of the cup 10. It can also reduce material loss and improve the comfort of the wearer. For example, the filling layer 12 is made of polyester fiber. Due to the low air permeability of the fiber, when the fiber contacts the skin, it is easy to cause skin itching and allergies for the wearer.

[0048] Please continue to refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the cup 10 further includes a cushion layer 14 , and the cushion layer 14 is located between the filling layer 12 and the outer covering layer 11 ; the outer edge of the filling layer 12 does not exceed the outer edge of the cushion layer 14 .

[0049] It can be understood that the cushion layer 14 is located between the filling layer 12 and the outer covering layer 11, and the outer edge of the filling layer 12 does not exceed the outer edge of the cushion layer 14, so that the cushion layer 14 has a complete shielding effect on the filling layer 12, especially when the filling layer 12 changes color after long-term use (for example, the polyurethane foam turns yellow), the cushion layer 14 cooperates with the outer covering layer 11 to shield the filling layer 12, which is beneficial to ensure the overall aesthetics of the cup 10, thereby effectively improving the service life of the cup 10; the cushion layer 14 can be made of fabric.

[0050] Please continue to refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the outer edge of the cushion layer 14 completely overlaps with the outer edge of the filling layer 12 ; and / or, the outer edge of the inner covering layer 13 does not exceed the outer edge of the cushion layer 14 .

[0051] It can be understood that the outer edge of the cushion layer 14 completely overlaps with the outer edge of the filling layer 12, that is, the outer dimensions of the cushion layer 14 are equal to the outer dimensions of the filling layer 12. The outer edge of the inner covering layer 13 does not exceed the outer edge of the cushion layer 14, that is, the outer dimensions of the cushion layer 14 can be greater than or equal to the outer dimensions of the inner covering layer 13, which is conducive to preventing the waste of cushion layer 14 materials, and at the same time can ensure the shielding effect of the cushion layer 14 on the filling layer 12, and is conducive to reducing the thickness of the cup 10, improving the lightness and thinness of the cup 10, and thus improving the comfort of the wearer.

[0052] In some embodiments, the outer covering layer 11 and the cushion layer 14 , the cushion layer 14 and the filling layer 12 , and the filling layer 12 and the inner covering layer 13 are all bonded by hot melt adhesive.

[0053] It can be understood that hot melt adhesive is pre-placed between the outer covering layer 11 and the cushion layer 14, between the cushion layer 14 and the filling layer 12, and between the filling layer 12 and the inner covering layer 13, and the layers are bonded by hot melt adhesive, which is conducive to improving the connection reliability between the layers, and eliminating the sewing edge is conducive to reducing the thickness of the cup 10, improving the lightness and thinness of the cup 10, and thus improving the comfort of the wearer. In addition, it is also conducive to preventing the layers of materials from moving due to molding during the process flow and delaminating due to washing after the finished product.

[0054] In some embodiments, the outer covering layer 11 and the filling layer 12 as well as the filling layer 12 and the inner covering layer 13 are bonded by hot melt adhesive.

[0055] It can be understood that hot melt adhesive is pre-placed between the outer covering layer 11 and the filling layer 12 and between the filling layer 12 and the inner covering layer 13, and the layers are bonded by hot melt adhesive, which is beneficial to improving the connection reliability between the layers, and the sewing edges are eliminated, which is beneficial to reducing the thickness of the cup 10, improving the lightness and thinness of the cup 10, and thereby improving the comfort of the wearer.

[0056] In some embodiments, the breast cup 10 includes one or more filling layers 12 .

[0057] It is understandable that the present application does not limit the filling layer 12 to be one layer. According to the actual production requirements of the cup 10, one or more filling layers 12 can be used between the outer covering layer 11 and the inner covering layer 13 to fill the gap between the outer covering layer 11 and the wearer's chest, and to effectively support and protect the wearer's chest.

[0058] In some embodiments, the cup 10 includes one or more inner covering layers 13 .

[0059] It is to be understood that the present application does not limit the inner covering layer 13 to be one layer. According to the actual production requirements of the cup 10, one or more inner covering layers 13 may be used on the side of the filling layer 12 away from the inner covering layer 13, and the filling layer 12 may be located between the outer covering layer 11 and one inner covering layer 13, or the filling layer 12 may be located between the layer of the inner covering layer 13 closest to the outer covering layer 11 and the outer covering layer 11, so as to hide the filling layer 12 and prevent the material of the filling layer 12 from changing color and being exposed to the outside after long-term use, thereby affecting the appearance.

[0060] Please refer to Figure 7 and Figure 8 In some embodiments, the cup 10 is molded, and the production process of the cup 10 includes: first, cutting out the shapes of the cushion layer 14, the filling layer 12, and the inner covering layer 13; second, spraying the top and bottom surfaces of the cushion layer 14 and the filling layer 12 with hot melt adhesive and letting them stand, and spraying the bottom surface of the inner covering layer 13 with hot melt adhesive and letting them stand; then, placing the cushion layer 14, the filling layer 12, and the inner covering layer 13 in the preset position on the outer covering layer 11 in turn, and using flat plate molding to make the outer covering layer 11, the cushion layer 14, the filling layer 12, and the inner covering layer 13 bonded and fixed to form a semi-finished product; finally, performing cup molding on the semi-finished product to obtain a finished product. This action can reduce the air between the layers, fully fit, improve the bonding effect, and also avoid delamination in subsequent washing tests.

[0061] A second embodiment of the present application further provides a bra, comprising the cup 10 as described above.

[0062] It can be understood that a bra generally includes two cups 10, a lower strap, shoulder straps and other structures, the lower straps and shoulder straps connect the two cups 10 and are fixed on the wearer; the bra provided in the present application adopts the above-mentioned cups 10, and the cups 10 have an outer covering layer 11 and a filling layer 12; the outer covering layer 11 forms an arc-shaped concave surface 111, and when the user wears it, the arc-shaped concave surface 111 is used to accommodate the wearer's breasts; the filling layer 12 is located in the arc-shaped concave surface 111, and the thickness and size of the filling layer 12 are designed according to the shape of the wearer's breasts to fill the gap between the outer covering layer 11 and the wearer's breasts, and has the function of supporting the wearer's breasts. The cup 10 has a supporting effect and improves the aesthetic effect of the body shape; compared with a bra cup formed by overlapping a fabric and a base material, the cup 10 provided in the present application omits the base material, and the cup 10 is composed of only an outer covering layer 11 and a filling layer 12. The filling layer 12 is installed on one side of the outer covering layer 11 located on the arc-shaped concave surface 111, and the filling layer 12 is only distributed in the part that needs support, which is conducive to reducing the thickness of the outer edge of the cup 10, avoiding causing the outer edge to be stiff, thereby improving the breathability, and helping to improve the comfort of the wearer, especially when wearing short-sleeved casual clothes, the thin outer edge of the cup 10 is conducive to making the wearer feel seamless and improving the wearing experience.

[0063] In summary, the present application provides a cup and a bra, wherein the cup has an outer covering layer and a filling layer, wherein the filling layer is installed on one side of the outer covering layer located on the arc-shaped concave surface. Compared with a bra cup formed by overlapping a fabric and a base material, the cup provided by the present application omits the base material. Since the filling layer is only distributed in a position that requires support, the thickness of the outer edge of the cup is reduced, thereby avoiding causing the outer edge to become stiff, thereby improving breathability.

[0064] The filling layer is located between the outer covering layer and the inner covering layer. The shape of the inner covering layer can be designed according to the shape of the filling layer, which is slightly wider than the filling layer to form a just coverage of the filling layer without causing material waste. In conjunction with the outer covering layer, the filling layer can be hidden to prevent the material of the filling layer from changing color and being exposed after long-term use, affecting the appearance.

[0065] The cushion layer is located between the filling layer and the outer covering layer, and the outer edge of the filling layer does not exceed the outer edge of the cushion layer, so that the cushion layer has a complete shielding effect on the filling layer, especially when the filling layer material changes color after long-term use (for example, the polyurethane foam turns yellow), the cushion layer cooperates with the outer covering layer to shield the filling layer, which is beneficial to ensure the overall aesthetics of the cup, thereby effectively improving the service life of the cup.

[0066] Moreover, the thin outer edge of the cup helps the wearer to achieve a seamless feeling and improves wearing comfort.

[0067] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0068] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or", "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0069] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. All equivalent structural changes made using the contents of the present application specification and drawings under the application concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
