Description

Technical Field

[0001] This utility model belongs to the field of underwear technology, specifically relating to a square cup anti-nipple bra suitable for large breasts. Background Technology

[0002] As underwear worn daily by women, the primary function of a bra is to cover, support, and protect the breasts. For women with large breasts, choosing the right bra is especially important, as it directly affects their comfort during daily activities, breast health, and overall appearance. However, current bra products on the market still have many shortcomings in meeting the specific needs of women with large breasts.

[0003] In terms of support, women with large breasts have greater breast weight and need bras to provide sufficient support to prevent sagging and wobbling. Currently, most women with large breasts choose full-cup bras. For example, Chinese patent CN207912073U discloses a deep-capacity bra that uses large padded full-cup bras to provide good support. However, full-cup bras cover a large area of ​​the breasts, which can easily cause the wearer to feel stuffy and constricted.

[0004] Breathability is a key concern for women with large breasts when choosing a bra. Because the skin on the chest has a large surface area and is prone to sweating, poorly breathable bras can cause stuffiness and dampness, leading to discomfort and potentially bacterial growth and skin problems. However, some bras on the market currently use non-breathable fabrics or complex structural designs in pursuit of appearance or support, severely compromising breathability.

[0005] Furthermore, the anti-nipple-showing function is also crucial for women with large breasts. In daily wear, nipple show-through not only affects appearance but can also cause embarrassment. However, some existing bras still have shortcomings in their anti-nipple-showing design. Summary of the Invention

[0006] In response to the problems in related technologies, this utility model proposes a square cup anti-protrusion bra suitable for large breasts to overcome the above-mentioned technical problems existing in the existing related technologies. The square cup eliminates the redundant coverage area of ​​the traditional full cup and reduces excess fabric to reduce stuffiness and constriction. In addition, the first molded cup achieves integrated optimization of breathability, thinness and anti-protrusion function through the overlapping design of the surface layer and the sandwich layer, combined with the anti-protrusion structure.

[0019] Furthermore, each of the first molded cups also includes a lining layer, wherein the outer fabric layer, the sandwich layer, and the lining layer are stacked sequentially;

[0020] The outer fabric layer is made of lace fabric, and the inner fabric layer is made of breathable fabric.

[0021] Preferably, the lining layer is made of modal fabric.

[0022] Furthermore, the anti-bump structure is a gel sponge layer, which is disposed between the sandwich layer and the lining layer;

[0023] The gel sponge layer has an anti-protrusion part at the corresponding nipple position, and the thickness of the anti-protrusion part is greater than the thickness of other parts of the gel sponge layer;

[0024] Preferably, the thickness of the anti-protrusion part is in the range of 4.0-6.0mm, and 5.0mm is preferred;

[0025] Furthermore, the thickness of the gel sponge layer gradually decreases from the anti-protrusion portion towards the surrounding edges.

[0029] Furthermore, the anti-bump structure is a microporous membrane, which is disposed between the sandwich layer and the inner fabric layer;

[0030] Preferably, the microporous membrane is a thermoplastic polyurethane membrane (TPU membrane); TPU membrane is a porous material with many tiny pores inside; when air flows through the TPU membrane, these pores allow air molecules to pass through, thereby achieving breathability;

[0031] Furthermore, the outer fabric layer, sandwich layer, microporous membrane, and inner fabric layer can be connected by various methods such as pressing, bonding, or sewing.

[0032] Furthermore, the bra body also includes an underband and left and right side bands; the underband is connected to the lower edge of the two square cups, and one side of the band is connected to the outer edge of the first molded cup; the band extends longitudinally from the underband beyond the upper edge of the square cups and narrows to form a dangling corner connected to the shoulder strap;

[0033] The bra body also includes micro-elastic cotton webbing; the micro-elastic cotton webbing extends longitudinally from the underband to the corners and is connected to the shoulder straps.

[0034] The micro-elastic cotton webbing is applied to the outer edge, the seam between the lower band and the webbing by means of adhesive or stitching.

[0059] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0060] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0061] Example 1

[0062] like Figure 1-5 As shown, this embodiment provides a square-cup anti-nipple bra suitable for large breasts, including a bra body. The bra body includes two square cups 1 arranged symmetrically on the left and right sides. Each square cup 1 includes a first molded cup 11 arranged in a square shape. Each first molded cup 11 includes an upper edge, an inner edge, a lower edge, and an outer edge. The upper edges of the two first molded cups 11 are connected by an upper edge 12, and the lower edges of the two first molded cups 11 are connected by a lower edge 13. The inner edge of each first molded cup 11 is connected to an inner edge 14.

[0063] It should be noted that: the square cup refers to the square cup 1 in this embodiment; this square cup is different from the traditional round, semi-circular, teardrop, and triangular cups, as it is a quadrilateral formed by connecting its four sides in sequence, as shown in the attached figure. Figure 4 As shown;

[0064] In this embodiment, the upper and lower edges are connected by a binding, and the inner edge is connected by an independent binding, forming a multi-directional support frame. This enhances the overall stability of the square cup 1 and the bra body, preventing the cup from shifting or deforming during exercise or daily activities. Simultaneously, the design of the upper and lower bindings and the inner binding 14 reduces friction and pressure marks when the square cup 1 fits against the breast skin, improving comfort during extended wear. Furthermore, the square cup 1 eliminates the redundant coverage area of ​​traditional round or teardrop-shaped cups, conforming to the breast contour and reducing excess fabric to decrease stuffiness and constriction.

[0065] A low-elasticity mesh 2 or a non-elasticity mesh 2 is connected between the two square cups 1; the low-elasticity mesh 2 or the non-elasticity mesh 2 extends from the lower edge 13 along the inner edge 14 to the upper edge 12; the upper and lower sides of the low-elasticity mesh 2 or the non-elasticity mesh 2 are connected to the upper and lower edges respectively, and its left and right sides are respectively connected to the inner edges 14 of the two square cups 1.

[0066] The low-elasticity mesh 2 or non-elasticity mesh extends longitudinally from the lower edge 13 along the inner edge 14 to the upper edge 12, and is tightly connected with the upper and lower edges and the inner edges 14 of the square cups 1 on both sides, forming a three-dimensional support structure. Its low-elasticity or non-elasticity characteristics can effectively limit excessive breast movement, enhance longitudinal support, and disperse lateral pressure, reducing the risk of displacement. At the same time, the mesh structure on the low-elasticity mesh 2 or non-elasticity mesh significantly improves the breathability of the middle part of the bra body, avoiding the accumulation of heat between the breasts. Moreover, by replacing the traditional heavy support structure with a lightweight design, a balance between support and breathability is achieved while reducing the coverage area and friction, which is especially suitable for users with large breasts, significantly improving wearing comfort and functionality.

[0067] Each of the first mold cups 11 includes an overlapping fabric layer 111 and a sandwich layer 112, and an anti-protrusion structure is provided on the skin-contact side of the sandwich layer 112;

[0068] It should be noted that the sandwich layer 112 is made of high-molecular synthetic fiber yarn, which is refined from petroleum. The sandwich layer 112 is typically woven on a warp-knitting machine and has three layers: upper, middle, and lower. The upper surface of the sandwich layer 112 usually has a mesh design, the middle layer is MOLO yarn connecting the upper and lower surfaces, and the lower surface is a densely woven flat surface. The three-dimensional mesh structure of the sandwich layer 112 gives it excellent breathability and moderate adjustability, earning it the reputation of "breathable mesh fabric." Furthermore, the sandwich layer 112 also has resilience and cushioning protection; the three-dimensional mesh structure can stretch under external force and automatically return to its original shape after the force is removed, providing excellent cushioning protection. Additionally, the sandwich layer 112 is lightweight, easy to wash and dry, and suitable for hand washing, machine washing, and dry cleaning. Moreover, the sandwich layer 112 is treated with anti-mildew and antibacterial agents to inhibit bacterial growth, meeting environmental protection requirements. In addition, the sandwich layer 112 is made of warp knitting, which is strong and durable and can withstand high-intensity tension and tearing.

[0069] It should be noted that the first molded cup 11, through the overlapping design of the outer fabric layer 111 and the sandwich layer 112, combined with the anti-nipple protrusion structure, achieves integrated optimization of breathability, thinness, and anti-nipple protrusion function. The sandwich layer 112 uses a three-dimensional mesh structure as a supporting skeleton, which significantly improves internal breathability and reduces heat buildup while maintaining the thinness of the first molded cup 11. This allows the bra body to meet the breathability and heat dissipation needs of users with large breasts, reduce the burden of wearing it through the thin design, and solve the embarrassment of nipple protrusion, thus balancing functionality and comfort.

[0070] Specifically, the anti-protrusion structure is a second molded cup 3, and the area of ​​the second molded cup 3 is smaller than the area of ​​the square cup 1;

[0071] More specifically, the second molded cup 3 is made of high-density breathable sponge.

[0072] Specifically, at least one side of the second molded cup 3 is connected to the edge of the square cup 1, and the upper end of the second molded cup 3 can movably cover the skin-contact side of the sandwich layer 112;

[0073] More specifically, at least one side of the second mold cup 3 is connected to the lower edge 13 by means of bonding or sewing; in this embodiment, sewing is preferred for connection.

[0074] Specifically, the shape of the second mold cup 3 is rabbit ear-shaped, oval, or heart-shaped;

[0075] More specifically, the second molded cup 3 is connected to the edge of the square cup 1 on at least two sides.

[0076] Specifically, the second molded cup 3 covers at least the nipple and areola of the human breast.

[0077] Specifically, the second mold cup 3 and the sandwich layer 112 are at least partially overlapped by adhesive or stitching.

[0078] It should be noted that in this embodiment, the square cup anti-nipple bra adopts a double-layer stacked cup anti-nipple design. The first layer refers to the first molded cup 11 formed by stacking the outer fabric layer 111 and the thin and breathable sandwich layer 112. The sandwich layer 112 allows the entire first molded cup 11 to bear parallel force, providing good support even without an underwire. However, the problem of nipple protrusion can occur with only the first layer. Therefore, this embodiment adds a second layer, which is the second molded cup 3. The second molded cup 3 is made of high-density breathable sponge and can be cut into different shapes as needed, including but not limited to the aforementioned rabbit ear shape, oval shape, or heart shape. The second molded cup 3 is mainly used to cover the nipple, thus retaining the bra's thin and breathable characteristics while solving the nipple protrusion problem.

[0079] Specifically, the bra body also includes a lower band 4 and left and right side bands 5; the lower band 4 is connected to the lower edge of the two square cups 1, and one side of the band 5 is connected to the outer edge of the first molded cup 11; the band 5 extends longitudinally from the lower band 4 beyond the upper edge of the square cup 1, and extends and narrows to form a hanging corner 51 connected to the shoulder strap 6.

[0080] The bra body also includes micro-elastic cotton webbing; the micro-elastic cotton webbing extends longitudinally from the underband 4 to the hanging corner 51 and is connected to the shoulder strap 6.

[0081] The micro-elastic cotton webbing is covered at the joint between the outer edge, the lower circumference 4 and the circumference 5 by means of adhesive or sewing.

[0082] In this embodiment, the micro-elastic cotton webbing is fixed by sewing; wherein, the micro-elastic cotton webbing, while covering the sewing joint, also has the function of lifting the square cup 1 upward; the micro-elastic cotton webbing lifts vertically upward from the lower part 4 to the hanging corner 51, which helps to prevent the breast from sagging.

[0083] Specifically, the underbust band 4 has a double-layer structure. This double-layer design, by increasing fabric thickness and structural strength, allows for a more secure fit to the underbust, reducing shifting due to movement. This design is particularly suitable for women with large breasts or during exercise, effectively distributing breast weight and preventing the bra from riding up.

[0084] Specifically, the band 5 on one side extends laterally from the outside of the square cup 1 to connect with the band 5 on the other side;

[0085] The band 5 is also connected to a first patch 52 and a second patch 53. The first and second patches cover a portion of the band 5, forming a double-layer structure; the area of ​​the band 5 not covered by the first and second patches forms a single-layer structure.

[0086] More specifically, the first patch 52 is L-shaped and is attached to the surrounding tape 5; the second patch 53 is vertical and is attached to the surrounding tape 5.

[0087] It should be noted that the band 5 achieves a balance between support, breathability, and fit through a combination of a partial double-layer structure (first patch 52 and second patch 53) and a single-layer structure. In the double-layer area, the L-shaped first patch enhances support on the opposite side of the chest, while the vertical second patch strengthens longitudinal support. In the single-layer area, the band 5 retains its basic elasticity, promoting air circulation by reducing fabric overlap and preventing stuffiness and heat buildup. With the combined effect of the two, the double-layer structure enhances support, while the single-layer structure ensures comfort and breathability, meeting the dual needs of large-breasted figures for support and lightness.

[0088] Specifically, the left and right side circumference bands 5 are connected to each other by fasteners.

[0089] More specifically, the fastener is an adjustable buckle 54 used to adjust the tightness of the bra.

[0094] Preferably, the lining layer 113 is made of modal fabric.

[0095] Specifically, the anti-protrusion structure is a gel sponge layer 8, which is disposed between the sandwich layer 112 and the lining layer 113.

[0096] The gel sponge layer 8 has an anti-protrusion part 81 at the corresponding nipple position, and the thickness of the anti-protrusion part 81 is greater than the thickness of other parts of the gel sponge layer 8.

[0097] Preferably, the thickness of the anti-protrusion part 81 is in the range of 4.0-6.0mm, and 5.0mm is preferred;

[0098] More specifically, the thickness of the gel sponge layer 8 gradually decreases from the anti-protrusion portion 81 to the surrounding edges, so as to achieve the local thickening design of the square cup 1;

[0099] It should be noted that the thickness of traditional sponges is generally greater than 8.0 mm, while the gel sponge layer 8 in this embodiment is compressed to a maximum thickness of only 5.0 mm through a pressing process; compared with traditional sponges, the gel sponge layer 8 is lighter and has better breathability.

[0103] More specifically, the methods of attachment include printing and bonding;

[0104] Preferably, the thickness of the silicone bump 9 is in the range of 0.2-0.3 mm;

[0109] Preferably, the microporous membrane 10 is a thermoplastic polyurethane membrane (TPU membrane); TPU membrane is a porous material with many tiny pores inside; when air flows through the TPU membrane, these pores allow air molecules to pass through, thereby achieving breathability;

[0110] More specifically, the outer fabric layer 111, the sandwich layer 112, the microporous membrane 10, and the inner fabric layer 113 can be connected by various methods such as pressing, bonding, or sewing.
