Technical Field
[0001] The utility model relates to the technical field of bras, in particular to a steel - free three - dimensional support large - coverage invisible fixed - cup bra. Background Art
[0002] Most of the existing daily large - size bras are steel - ring molded - cup bras or soft - cup bras. Due to the requirements of practical wear resistance, the comfort is greatly reduced, and they are only suitable for the most basic wearing functions. Such bras lack the demand for comfort and steel - free for large breasts. The existing large - size bras mainly have the following defects:
[0003] 1. Steel - ring products reduce comfort while providing support for large breasts;
[0004] 2. Steel - free molded - cup products have poor wearing adaptability;
[0005] 3. Steel - free stuffed - cup products have difficulty in fixing the cups, and are prone to displacement and deformation during wearing and washing;
[0006] 4. Steel - free soft - cup products are prone to nipple show - through and have a slightly poor breast shape when worn. Content of the Utility Model
[0007] The technical problem to be solved by the utility model is to provide a steel - free three - dimensional support large - coverage invisible fixed - cup bra in view of the deficiencies mentioned in the above background art.
[0008] To solve the above - mentioned technical problem, the technical solution provided by the utility model is: a steel - free three - dimensional support large - coverage invisible fixed - cup bra, including symmetrically arranged cup bodies. A cup seam is sewn in the middle of the cup bodies. Rear wings are sewn on the outer sides of the cup bodies. An integrated elastic lower band is sewn at the bottom of the cup bodies, the cup seam and the rear wings. Buckles that cooperate with each other are sewn on the outer sides of the rear wings and the elastic lower band at the bottom on both sides. A three - dimensional 3D molded cup is sewn inside the cup bodies. A date - pit - shaped wide ear non - elastic band is sewn at the top of the cup bodies. A shoulder strap is sewn between the end of the date - pit - shaped wide ear non - elastic band and the top of the rear wing.
[0009] Further, the cup body is made of non - elastic breathable mesh fabric to ensure breathability.
[0010] Further, the three - dimensional 3D molded cup is an impact - molded cup, and the one - piece punching mold ensures three - dimensional comfort, fitting and support.
[0011] Further, the rear wing is in a seamless U - shape to ensure the back side.
[0012] Further, the cup seam is triangular, and the cup seam is made of non - elastic structural fabric.
[0013] Furthermore, the elastic lower scoop is provided with an inner wrapped rebound towel.
[0014] Furthermore, cotton-like binding towels are installed at the edges of the shoulder straps, the main body of the cup, the back part, and the edges of the elastic lower scoop.
[0015] The advantages of a non-wired three-dimensional supporting large-coverage invisible fixed-cup bra of the present utility model compared with the prior art are as follows: The cup is provided with a zero-sensation four-way stretch material structure corresponding to the left and right sides of the chest in the front panel, and a 3D molded cup is fixed by a middle seam. It is sewn together with an invisible U-shaped back part and an integrated lower scoop structure to form a non-wired invisible fixed-cup supporting three-dimensional full-coverage bra, which fits the chest curve. The molded cup comfortably and three-dimensionally wraps the chest fat and can create a round and perfect chest line. It is comfortable and sensation-free when worn and effectively avoids chest protrusion. The middle layer selects a non-elastic breathable fabric based on mechanical principles and acts on the side of the cup and the front wide shoulder strap, ensuring comfort while having better lifting and stability for people with large breasts, and effectively avoiding chest shape spreading outwards. This non-wired invisible fixed-cup supporting three-dimensional full-coverage bra can meet the needs of long-term wearing. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following further elaborates on the present utility model in detail with reference to the drawings.
[0022] Combined with the attached Figures 1-4, a wireless steel ring three-dimensional support large-coverage invisible fixed-cup bra, including symmetrically arranged cup bodies 1. The cup bodies 1 are made of non-elastic breathable mesh fabric. A cup seam 2 is sewn in the middle of the cup bodies 1. The cup seam 2 is triangular in shape and is made of non-elastic structural fabric. Rear wings 3 are sewn on the outer sides of the cup bodies 1. The rear wings 3 are in a seamless U-shaped setting. A one-piece elastic bottom band 4 is sewn at the bottom of the cup bodies 1, the cup seam 2 and the rear wings 3. The elastic bottom band 4 is internally wrapped with a resilient webbing. On both sides, buckles 7 that cooperate with each other are sewn on the outer sides of the rear wings 3 and the elastic bottom band 4 at the bottom. A three-dimensional 3D mold cup 8 is sewn inside the cup bodies 1. The three-dimensional 3D mold cup 8 is a stamping cup. A date-pit-shaped wide ear non-elastic band 5 is sewn at the top of the cup bodies 1. A shoulder strap 6 is sewn between the end of the date-pit-shaped wide ear non-elastic band 5 and the top of the rear wings 3. Cotton-feeling edge-binding towels are installed at the edges of the shoulder strap 6, the cup bodies 1, the rear wings 3, and the elastic bottom band 4.
[0023] Figures 1-4 When the shown bra is worn, it is comfortable and feels nothing, prevents nipple protrusion, and can create a perfect breast line shape. It includes a three-piece three-dimensional structure made of zero-sense four-way stretch material arranged on the front of the cup: the cup body 1, the cup seam 2, and the rear wing 3. A three-dimensional 3D stamping cup is arranged inside the cup body 1. 2. The cup seam 2 is a triangular one-piece fitting and shaping three-in-one non-elastic structural fabric. 3. A three-dimensional soft mold cup sewn and fixed in the middle layer of the cup. 4. A seamless U-shaped is arranged on the rear wing 3 of the cup, which comfortably wraps the back and smooths the back fat. 5. A date-pit-shaped wide ear non-elastic band with an appropriate width on the front ear. 6. A one-piece elastic bottom band 4, internally wrapped with a high-resilience webbing, comfortable and not tight.
[0024] As shown in the figure, in this embodiment, the bra is set as a wireless steel ring large-coverage invisible fixed-cup support three-dimensional full-cup bra. A date-pit-shaped wide ear non-elastic band 5 with an appropriate width is horizontally arranged above the cup body 1, which is connected to the shoulder strap 6 to form a stable lifting force point. A cup seam 2 made of a triangular one-piece fitting and shaping three-in-one non-elastic structural fabric is arranged in the front of the bra, which is connected to the zero-sense four-way stretch material on the left and right sides. A three-dimensional 3D mold cup 8 is sewn in the middle, and is sewn and fixed to the middle layer with the cup body 1 made of non-elastic breathable mesh fabric. It is convenient to wear and wash without displacement, comfortable to wear and has support. A one-piece elastic bottom band 4 is arranged at the bottom of the bra, and its width is normally about 30MM. The cup collar edge, the side bend is connected to the upper part, and the seamless U-shaped rear wing 3 is made of an ultra-fine cotton-feeling elastic edge-binding webbing, comfortable and not rubbing the skin. The whole cup fabric is skin-friendly and comfortable. Without a steel ring, it has better lifting and stability for people with large breasts, and effectively avoids breast shape spreading. This wireless steel ring large-coverage invisible fixed-cup support three-dimensional full-cup bra can meet the needs of long-term wearing.
