Description

Technical Field

[0001] This utility model belongs to the field of underwear technology, specifically relating to an adjustable thickness molded cup structure and its bra. Background Technology

[0002] Backless bras, as a popular type of underwear, are widely used in women's daily wear and fashion styling. For example, Chinese patent CN205337642U discloses a bra that can lift the bust and beautify the back. This bra includes two cups with underwires, an underband, side wings, two shoulder straps, and a pair of back clasps. The bra can adjust the wearing force according to the wearer's needs and body shape through the combination of adjustable shoulder strap clasps, front shoulder strap adjustment clasps, and back shoulder strap adjustment clasps, thus increasing the adjustment range. Furthermore, the four adjustment points, namely the front shoulder strap hook, the back ear adjustment clasp, and the front and back ear hooks, increase the variety of adjustment point combinations and achieve the effect of lifting the bust and beautifying the back.

[0003] However, in practical applications, the cup structure of existing backless bras still has many shortcomings, especially the lack of adjustable cup thickness, which severely limits their applicability and functionality. Current backless bras typically use a fixed-thickness molded cup design, such as a single layer of sponge or cotton. This makes the bra suitable only for women with specific breast shapes. For example, while a bra with excessively thick cups can provide a fuller effect for women with small breasts, it will appear too bulky for women with large breasts, failing to achieve the desired slimming effect; conversely, a bra with excessively thin cups cannot satisfy the desire for a fuller appearance among women with small breasts. This design results in some backless bras only being suitable for women with large or small breasts, failing to cater to the needs of users with different breast shapes, thus limiting their applicability and functionality.

[0004] Furthermore, existing backless bras are inadequate in terms of support and shaping. Because the cup thickness is fixed and lacks an adjustable mechanism, the bra cannot dynamically adjust its support according to the wearer's breast shape, resulting in insufficient support or excessive compression, affecting comfort and aesthetics. Especially for one-piece molded cup structures, in pursuit of stability, excessively thick and rigid filling materials are often used, making the overall molded cup too heavy, creating a feeling of pressure when worn, and potentially leading to discomfort with prolonged use.

[0005] In addition, the thick molded cups have poor breathability and heat dissipation, and tend to accumulate sweat in hot seasons or during exercise, causing skin allergies or stuffiness, which cannot meet the needs of modern women for lightweight and healthy clothing. Summary of the Invention

[0021] Furthermore, both the first and second fabrics are made of fine-textured fabric, which is woven from polyester or cotton blended materials.

[0022] Furthermore, the inner sides of the two mold cup bodies are connected to form a butterfly shape.

[0023] Furthermore, the intermediate cotton layer is made of slow-rebound memory foam core with a density of 45D-55D.

[0024] Furthermore, hot melt adhesive is provided on both sides of the middle cotton layer, and the outer breathable layer, the middle cotton layer and the inner breathable layer are formed into an integral structure through a hot melt composite process.

[0025] Furthermore, the first lining fabric is fully bonded to one side of the intermediate cotton layer; the second lining fabric is separated from the intermediate cotton layer in the area corresponding to the cotton pad insertion structure to form the accommodating pouch, while the remaining area is bonded to the intermediate cotton layer.

[0026] Furthermore, the lower part is provided with a mounting part at the connection between the second edge and the third edge, and the mounting part is used to connect with the connector.

[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 1-7As shown, this embodiment provides a molded cup structure with adjustable thickness. The molded cup body 1 includes an outer breathable layer 11, a middle cotton layer 12, and an inner breathable layer 13 arranged sequentially from the outside to the inside. The three layers are bonded together to form a cup portion 14 and a bottom portion 15 as an integral structure. A cotton pad insertion structure 2 is provided between the inner breathable layer 13 and the middle cotton layer 12. The cotton pad insertion structure 2 corresponds to the lower area supporting the breast. The cotton pad insertion structure 2 includes at least one accommodating pouch, at least one filling pad 3, and an insertion seam 21 provided on the accommodating pouch and communicating with its interior. The filling pad 3 is inserted or removed through the insertion seam 21 to adjust the thickness of the molded cup body 1.

[0063] The molded cup body 1 includes an inner surface for contact with the skin and an outer surface away from the skin; the inner surface of the cup portion 14 is a concave curved surface, and the outer surface of the cup portion 14 is a continuous convex curved surface.

[0064] When the filling pad 3 is placed into the accommodating bag, it causes the inner surface of the cup portion 14 corresponding to the area of ​​the cotton pad insertion structure 2 to change from an inwardly concave curved surface to an outwardly convex curved surface, at which time the thickness of the mold cup body 1 increases.

[0065] Firstly, the adjustable-thickness molded cup structure, through the cotton pad insertion structure 2, includes a accommodating pouch, a filling pad 3, and an insertion seam 21. The thickness of the molded cup body 1 can be easily adjusted by inserting or removing the filling pad 3 through the insertion seam 21. For women with small breasts, increasing the filling pad 3 changes the inner surface of the cup portion 14 from a concave to a convex surface in the corresponding area, increasing the thickness of the molded cup body 1 and achieving a good gathering effect. For women with large breasts, reducing or removing the filling pad 3 reduces the thickness, meeting the needs of women with different breast shapes and providing a personalized wearing experience.

[0066] Secondly, the main body 1 of the molded cup is composed of an outer breathable layer 11, a middle cotton layer 12, and an inner breathable layer 13, which are fitted together to form an integrated structure. The multi-layer breathable design allows air to circulate smoothly between the inside and outside of the molded cup, effectively expelling moisture and heat generated in the chest, keeping the chest dry and comfortable, reducing problems such as bacterial growth caused by stuffiness and dampness, and improving the comfort and health of wearing the garment.

[0067] Furthermore, while achieving adjustable thickness, the overall structure emphasizes the rational combination of materials in each layer. The outer breathable layer 11, the middle cotton layer 12, and the inner breathable layer 13 work together to avoid the use of excessively heavy materials while ensuring the stability and functionality of the molded cup structure, thus achieving a lightweight design. This reduces the burden on the chest from the molded cup, preventing women from feeling excessive pressure and fatigue during prolonged wear, and enhancing the comfort of wearing the garment.

[0068] The cup portion 14 adopts a structure that is thinner at the top and thicker at the bottom, and the lower part 15 adopts a wire-free structure, which reduces the pressure of the cup body 1 on the intercostal space of the human body by 32%.

[0069] Specifically, the molded cup body 1 includes a first edge 16, a second edge 17 and a third edge 18. The first edge 16 extends upward from the outer edge of the breast to connect with the second edge 17. The second edge 17 extends sequentially along the upper and inner edges of the breast. The two ends of the third edge 18 are respectively connected to the lower ends of the first and second edges.

[0070] The accommodating pouch extends diagonally downward from a position near the first edge 16 toward the lower end of the second edge 17 and narrows thereto to enhance the gathering effect.

[0071] More specifically, the first, second, and third edges are all curved, and the curvature of the first edge 16 is less than that of the second edge 17, so as to better fit the curve of the human breast.

[0072] Specifically, the insertion slot 21 extends obliquely upward toward the second edge 17; the extension direction of the insertion slot 21 forms an angle α with the longitudinal central axis of the mold cup body 1, and the value of the angle α is in the range of 15°-30°, so as to facilitate the insertion and removal operation of the filling pad 3 and prevent it from falling off.

[0073] Specifically, the area of ​​the cotton pad insertion structure 2 accounts for 30%-50% of the area of ​​the molded cup body 1, so as to avoid the area being too large and thus damaging the stability and breathability of the overall structure of the molded cup, and to ensure that the molded cup body 1 can achieve flexible thickness adjustment while maintaining good support and air circulation, thereby improving wearing comfort and functionality.

[0074] Specifically, the thickness of the filling pad 3 decreases from the center to the surrounding edges, and the maximum thickness of the filling pad 3 ranges from 0.9 to 1.2 cm. In this embodiment, it is preferably 1.0 cm to increase the thickness of the mold cup body 1.

[0075] Specifically, the filling pad 3 is crescent-shaped, and laboratory pressure tests show that its gathering efficiency is improved by 40%.

[0076] Specifically, the outer breathable layer 11 and the inner breathable layer 13 are both double-layer composite fabric structures. The double-layer composite fabric structure includes an inner breathable surface 131 and an outer contact surface. The inner breathable surface 131 is provided with a plurality of breathable holes 1311.

[0077] Specifically, the outer breathable layer 11 includes a first lining fabric and a first outer fabric that are bonded together, and the inner breathable layer 13 includes a second lining fabric and a second outer fabric that are bonded together; both the first and second lining fabrics are used to bond with the middle cotton layer 12.

[0078] More specifically, both the first and second lining fabrics are made of porous and breathable fabric, and in this embodiment, an eight-hole fabric is preferred.

[0079] It should be noted that the surface of this eight-hole fabric is provided with a honeycomb-shaped air vent array structure, which includes multiple square hole groups, and each square hole group includes eight air vents 1311 arranged in a square.

[0080] The design of the honeycomb-shaped air vent array structure reduces the overall weight of the mold cup body 1 by 25% and increases the air permeability by 35%.

[0081] More specifically, both the first and second fabrics are made of fine-textured fabric, which is woven from polyester or cotton blended materials;

[0082] It should be noted that both the outer breathable layer 11 and the inner breathable layer 13 are double-layer composite structures formed by combining an eight-hole fabric and a fine-faced fabric side-to-side. Because this double-layer composite structure has a suitable thickness, it effectively avoids bursting when using ultrasonic cutting technology to cut the mold cup body 1. In contrast, a single layer of spandex fabric that is too thin is prone to bursting in this process due to insufficient strength. Therefore, the double-layer composite structure used in this embodiment, while ensuring breathability and lightweight characteristics, also significantly improves the yield rate of ultrasonic cutting, ensuring that the edges of the mold cup body 1 are aesthetically pleasing, seamless, and free from bursting.

[0083] Specifically, the inner sides of the two mold cup bodies 1 are connected to form a butterfly shape.

[0084] Specifically, the middle cotton layer 12 is made of slow-rebound memory foam core with a density of 45D-55D; compared with similar products on the market, even if the user wears it for 8 consecutive hours, the structural deformation rate is reduced by 60%.

[0085] Specifically, hot melt adhesive is provided on both sides of the middle cotton layer 12, and the outer breathable layer 11, the middle cotton layer 12 and the inner breathable layer 13 are formed into an integral structure through a hot melt composite process.

[0086] Specifically, the first lining fabric is fully attached to one side of the intermediate cotton layer 12; the second lining fabric is separated from the intermediate cotton layer 12 in the area corresponding to the cotton pad insertion structure 2 to form the accommodating pouch, while the remaining area is attached to the intermediate cotton layer 12.

[0087] Specifically, the lower part 15 is provided with a mounting part 151 at the connection between the second edge 17 and the third edge 18, and the mounting part 151 is used to connect with the connector 10.

[0088] Example 2

[0089] like Figure 8-12 As shown, this embodiment provides a bra. Features not explained in this embodiment can be explained using the methods described in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is as follows:

[0090] The bra includes the molded cup structure described in Embodiment 1, and the molded cup structure includes two symmetrically arranged molded cup bodies 1 on the left and right.

[0091] The bra also includes two front panels 4, two lifting straps 6, two back panels 5, and a back band 7;

[0092] One end of the front piece 4 extends toward the human shoulder and forms a splicing part 8 with the rear piece 5 on the front side of the human shoulder;

[0093] The other end of the front piece 4 extends toward the mold cup body 1 and is connected to the first edge 16 and the second edge 17 of the mold cup body 1 respectively; the side edge of the front piece 4 is connected to the side edge of the rear piece 5.

[0094] The left and right ends of the rear band 7 are respectively connected to the lower end of the second edge 17 of the mold cup body 1; and the lower edges of the front piece 4 and the rear piece 5 are both connected to the rear band 7.

[0095] Each of the lifting straps 6 extends from the upper end of the mold cup body 1, passes sequentially through the front piece 4, the splicing part 8, and the rear piece 5, and extends integrally to the rear band 7; the integral extension design of the lifting straps 6 is conducive to forming a continuous and stable lifting path.

[0096] More specifically, the lifting strap 6 is connected to the skin-contact surface of the front piece 4 and the back piece 5, which can maintain the lifting effect of the lifting strap 6 on the chest and ensure aesthetics.

[0097] Specifically, the front piece 4 and the back piece 5 are both lace pieces, and the front piece 4 and the back piece 5 are connected at the human shoulder to form a lace shoulder strap;

[0098] Specifically, the lifting strap 6 is an elastic band; the back band 7 is an elastic fiber towel, which provides support and is paired with lace shoulder straps to achieve a pressure-relieving and seamless effect;

[0099] More specifically, the elasticity of the lifting strap 6 is different from that of the rear band 7.

[0100] Specifically, the two back pieces 5 partially overlap to form a V-shaped open back, thus achieving a beautiful back effect.

[0101] Specifically, the inner sides of the two molded cup bodies 1 are movably connected to the front of the bra via connectors 10 to facilitate the user's wearing and removal;

[0102] More specifically, the connector 10 includes, but is not limited to, hook and loop fasteners, snap fasteners, snap-on fasteners, zipper fasteners, and Velcro fasteners.

[0103] In this embodiment, a snap-on connection structure is preferred to further improve the ease of putting on and taking off the garment.

[0104] Specifically, a sealing edge 9 is provided at the connection between the mold cup body 1 and the front piece 4, and the sealing edge 9 is provided on the inner surface of the mold cup body 1;

[0105] More specifically, the sealing edge 9 starts from the third edge 18, extends along the edge of the mold cup body 1, and completely covers the first edge 16, while partially covering the second edge 17;

[0106] The edge sealing 9 helps to avoid friction against the skin at the connection point, improves wearing comfort, and further reinforces the edge of the molded cup body 1.

[0107] The bra described in this embodiment is suitable for various styles. For example, it can be worn as an inner layer under a slip dress or suit for everyday wear to create a "refined skin-revealing look"; it can be paired with a backless dress for a date to enhance the sexy atmosphere; it can also be used as an outer layer with a "fake collar" to add a sense of design to a simple top; moreover, from daily commutes to dates and parties, one bra meets the needs of multiple occasions, saving the trouble of repeated matching, and has a very high cost performance. It takes into account both "beauty" and "comfort", and comprehensively covers women's needs from details to scenarios. It is an "invisible weapon" to improve the quality of clothing.
