Abstract
Description
Technical fields:
[0001] This utility model belongs to the field of women's underwear, specifically a bra with composite support. Background technology:
[0002] With the continuous development of science and technology, existing women's bras are increasingly focused on functionality, leading to continuous improvements in support, coverage, and comfort for the breasts. Previously, the main processing method was sewing, with an underwire at the lower edge of the molded cups. Sewn bras offered good fit and support, but their drawbacks were also obvious: they were relatively stiff and less comfortable to wear. With further technological advancements and process selection, manufacturers increasingly use the more efficient hot-pressing process. Bras bonded by hot pressing offer better comfort. However, the use of underwires in hot-pressing reduces the product yield rate. Therefore, most manufacturers have abandoned underwire structures, opting instead for a support structure made of piled-up cotton forming hardened strips. The drawback of this method is also obvious: it is relatively soft, provides poor breast shaping, and is prone to shifting, commonly known as "cup slippage." Summary of the Invention:
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bra with composite support that can overcome the above-mentioned shortcomings.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a bra with composite support, the key being that the bra includes a glued cup cavity, back straps, shoulder straps, and molded cups. The cup cavity includes a left cup cavity and a right cup cavity, and the molded cups include a left cup and a right cup. The two ends of the back straps are connected to both sides of the cup cavity, and the shoulder straps include a left shoulder strap and a right shoulder strap, each connected between the cup cavity and the back strap. Each of the left and right cup cavities has a supporting bob and a covering fabric on its outer surface. The supporting bob is located on the lower edge of the left and right cup cavity. An outer support piece is attached to the outer side of the left and right cup cavities, with the upper end of the support piece connected to the shoulder strap and the outer side pressed against the supporting bob and the covering fabric. The molded cups are an integral structure, that is, the left and right molded cups have a connecting strap in the middle, achieving a one-piece structure.
[0005] The aforementioned support bone position is on an imaginary arc line 5-10mm above the lower end of the left / right cup cavity.
[0006] The adhesive covering fabric is a one-piece structure, covering the supporting adhesive bones from the left cup cavity to the right cup cavity.
[0007] The supporting glue covers the lower edge of the left / right cup cavity and extends to the side of the cup. The distance from the supporting glue to the chicken core is 5-10mm, and the distance from the supporting glue to the upper edge of the left / right cup cavity is 5-10mm.
[0008] A reinforcing strip with a chicken core is provided in the middle of the cup cavity.
[0009] This invention relates to a composite support bra by adding supporting boning and a covering fabric structure to the outside of the heat-pressed bra cup. The supporting boning is installed in the cup cavity, so that when the bra is in use, the skin folds under the breast will bend the lower edge of the cup and form a buffer interval for the supporting boning, improving the overall comfort of the bra. It also has the fit and support of a sewn bra. When used with an outer support piece, it can achieve breast gathering and support, creating an overall shaping effect. Furthermore, the internal buffer pad required by the original design due to the boning can be omitted, effectively saving production costs. Attached image description:
[0010] Figure 1 This is a schematic diagram of the structure of this utility model.
[0011] Figure 2 This is a schematic diagram of the back structure of this utility model. Detailed implementation method:
[0012] like Figures 1 to 2As shown, a bra with composite support includes a glued cup cavity 1, back straps 2, shoulder straps 3, and molded cups 4. The cup cavity 1 includes a left cup cavity 11 and a right cup cavity 12. The molded cups 4 include a left cup and a right cup that are integrally or separately connected. The two ends of the back straps 2 are connected to the two sides of the cup cavity. The shoulder straps 2 include a left shoulder strap and a right shoulder strap, each connected between the cup cavity and the back straps. The outer surfaces of the left and right cup cavities are each provided with... The bra includes a support bob 5 and a bob cover fabric 51. The support bob is located on the lower edge of the left / right cup cavity. When the bra is worn, the folds along the lower edge of the breast will bend the lower edge of the molded cup and trap the support bob 5 within the folds. The bent lower edge of the molded cup becomes an inner support pad for the support bob 5, reducing the pressure on the body. An outer support piece 6 is attached to the outer side of the left / right cup cavity. The upper end of the outer support piece is connected to the shoulder strap, and the outer side is pressed against the support bob and the bob cover fabric. The left and right cups are a one-piece structure with an opening at the gore position for the integrated molded cup to be inserted. The left cup cavity 11 and the right cup cavity 12 are both cavity structures formed by pressing the front and back panels together at the edges. The back strap 2 can be a one-piece structure or it can have a break at the back with a buckle and a fastener at each end of the break. The left and right shoulder straps are respectively connected to the corresponding upper edges of the left and right cup cavities, and are connected to the back straps at the other ends. The supporting bob 5 can be made of nylon or hard plastic. The bob covering fabric 51 covers and fixes the supporting bob 5 to the bra. The outer support piece 6 is a strip that conforms to the shape of the outer side of the molded cup. Since the front of the left and right cup cavities is a single piece of fabric, the overall tensile strength is low. The outer support piece 6 can strengthen the tensile strength from the outside of the molded cup cavity. The shape of the bob covering matches the supporting bob, so that it can cover the supporting bob sufficiently. As another embodiment, the molded cup includes an integrally connected left cup and right cup, with an opening in the middle of the cup cavity for the integrally connected molded cup to be inserted. The outer support piece 6 and the supporting bob 5 cooperate with each other to achieve a firm support and gathering effect for the breast, achieving a composite support effect.
[0013] The aforementioned support bob 5 is located on an imaginary arc line 5-10mm above the lower end of the left / right cup cavity. The support bob 5 is pressed onto the lower end of the left / right cup cavity, gradually moving outwards from the side of the left / right cup cavity, finally coinciding with the outer edge of the left / right cup cavity on its outer side. This overlapping and pressing of the support bob 5 onto the lower end of the left / right cup cavity reduces the direct pressure on the body caused by a stiff support bob, improving bra comfort and reducing the need for a component, thus lowering production costs.
[0014] The adhesive covering fabric 51 is a one-piece structure. The adhesive covering fabric 51 covers the supporting adhesive bones from the left cup cavity to the right cup cavity, and its function is to fix and support the adhesive bones 5.
[0015] The supporting boning covers the lower edge of the left / right cup cavity and extends to the side of the cup. The distance from the supporting boning to the core is 5-10 mm, and the distance from the supporting boning to the upper edge of the left / right cup cavity is 5-10 mm. Longer supporting boning can form a supporting contour along the outer edge of the left / right cup cavity, reducing the possibility of breast slippage and improving support and comfort. Preferably, it is 6-7 mm. The above distances are the maximum distances from the lower edge of the arc.
[0016] A reinforcing strip 7 is provided in the middle of the cup cavity. This reinforcing strip increases the flexibility of the connection between the left and right cup cavities, improving resistance to deformation. It reduces the degree of body twisting and cup deformation, minimizing the possibility of cup slippage.
[0017] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
