Description

Technical Field

[0001] The utility model relates to the field of clothing, in particular to a fitted, seamless vest chest circumference designed for growing girls and used to remind them to straighten their backs. Background Art

[0002] At present, most of the back-supporting products on the market can only be worn outside, and they are made of traditional sewing technology. Back-supporting products for outer wear are extremely inconvenient for children. Not only will they make children feel embarrassed and unwilling to wear them, but some sensitive children will also resist such products. In addition, the traditional sewing technology will leave indentations or underwear line marks when worn. For example, the Chinese utility model patent applied for by the applicant, with application number 202021070694.3, is a vest bra designed for girls. It uses the traditional full-sewing technology. Not only will there be line marks when worn, but the tensile force of the fabric is limited due to sewing problems. Wearing it too tight or uncomfortable will also cause blood circulation problems; for example, the front and rear shoulder straps are sewn by sewing technology, so that even the best fabrics will press on the skin. For example, the back is sewn by sewing technology to form an H-shaped structure. After wearing it all day, there will be line marks on the skin, which is not only uncomfortable but also unsightly. In addition, the length of the lower leg of 1.5cm-2.5cm cannot meet the needs of girls who are in the developmental stage, making them feel shy or embarrassed when they initially accept wearing a bra.

[0003] For example, the girls' underwear disclosed in Patent No. 202320532652.4 has an integrated patch structure connected by sewing. Due to the sewing, it often leaves indentations when stretched, leaving red marks on the girl's delicate skin. When sweating, the sewn parts press against the skin, causing stuffiness and lack of ventilation.

[0004] Every girl wants to be graceful, but the academic pressure makes them easily ignore their body development, which can easily lead to unhealthy body shapes such as hunchback and pigeon chest over time. Therefore, it is necessary to specially design a bra that can be worn inside to straighten the back to avoid embarrassment and leave no marks, which is suitable for different stages of breast development of girls. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a close-fitting, seamless vest bra that reminds girls to straighten their backs, which is specially designed for growing girls.

The front part of the underwear is equipped with a "W" chest protection structure, and the middle part of the neckline is equipped with several ventilation holes to prevent stuffiness. The surface layer and the inner layer of the cup are made of cool and thin breathable fabrics. The back of the underwear is a thin mesh breathable elastic fabric that fits the skin more comfortably, so as to avoid sweating and pressing the flesh during exercise. In daily wear, girls can protect their breasts and remind their backs to develop the habit of naturally straightening their backs. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Embodiment 4: Figure 6 As shown, on the basis of the above-mentioned second embodiment, a strip-shaped pad cup disassembly opening 22 is provided in the middle of the cup inner layer 13, and a connecting cloth 23 is sewn between the pad cups 4 on the left and right sides, and the connecting cloth 23 corresponds to the position of the strip-shaped disassembly opening 22 of the cup inner layer 13. The pad cup 4 can be integrally disassembled between the cup surface layer 11 and the cup inner layer 13, and the pad cup 4 can be replaced based on the actual situation of the user.

[0047] Embodiment 5: Figure 7-9As shown, based on the above-mentioned embodiment 3 or embodiment 4, the pad cup 4 is a thin small round cup pad, which is soft and comfortable and protects the sensitive nipples of girls whose breasts are initially developing; the pad cup 4 includes three layers: a middle layer of sponge, a first layer of elastic fabric attached to the inside of the sponge, and a second layer of elastic fabric attached to the outside of the sponge. The middle layer of sponge is provided with a number of air holes. Corresponding to the stage of breast uplift development, girls at this stage have accepted the habit of wearing bras, and the deepest concave dimension of the pad cup 4 is preferably 2cm-2.5cm, such as a depth of 2cm, 2.2cm or 2.5cm. The inner layer 13 of the cup and the pad cup 4 are both designed with reserved capacity.

[0048] In the above embodiment, the gluing method can be machine-dispensing gluing or manual-dispensing gluing;

[0049] The width of the underpinning 5 can be 2.5cm-4cm, and the style is made to be a little longer than the chest of a vest, and the appearance is similar to a bottoming vest. In order to reduce the shyness or embarrassment of girls in the initial stage of breast development when they first accept wearing a bra, the width of the underpinning 5 is preferably 2.5cm, 2.8cm, 3cm or 3.5cm;

[0050] The ends of the front shoulder strap 3 and the upper ends of the left rear shoulder strap 6 and the right rear shoulder strap 7 are reinforced with reinforced stitches on both sides. The length of the reinforced stitches can be 0.5-1.5 cm, and the length of the reinforced stitches is preferably 0.5 cm, 0.8 cm, 1 cm, 1.2 cm, and 1.5 cm;

[0054] In the above embodiment, the front panel 1 of the underwear includes a surface layer 14, a cup surface layer 11, and a cup inner layer 13. The cup surface layer 11 is made of a cool ultra-thin fabric with air holes that can be cut as desired. The surface layer 14, the first traction belt 8, and the second traction belt 9 are fabrics that can be cut as desired with air holes. The fabrics are directly cut. The inner layer 13 of the cup uses 100% air hole fabric. The back panel 2 of the underwear is a thin mesh breathable elastic fabric. It is comfortable to wear without leaving any line marks, achieving a traceless and pressure-free effect, solving the problem of discomfort caused by underwear line marks or excessive pressure on the skin when worn by traditional sewing technology. In addition, the back panel 2 of the underwear is a thin mesh breathable elastic fabric that fits the skin better. The laminating process used does not press the skin. The elastic thin mesh breathable fabric not only increases the stretching force, but also allows the sweat to fully evaporate without stuffing the skin.

[0055] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field are deemed to fall within the protection scope determined by the claims of the present invention.
