AI Technical Summary

Technical Problem

Existing size-free bras can feel constricting for women with full busts. Deep V-neck styles, due to their super-elastic fabric, tend to stretch, causing the shoulder straps and center gore to stretch and widen, thus affecting the wearing experience.

Method used

Non-elastic reinforcing pieces are installed at the ear loops of the unsized bra, and slightly elastic reinforcing pieces are installed at the center gore. A U-shaped notch and elastic band are designed at the top center of the back panel, and the layers of fabric are fixed by adhesive bonding.

Benefits of technology

It effectively prevents the fabric from stretching at the ear loops and center gore, improving the wearing comfort for those with a fuller bust. The back panel is also more stable and less likely to ride up.

Description

Technical Field

[0001] This utility model relates to the field of size-free underwear technology, specifically to a deep V-shaped size-free bra that improves breast shape by preventing outward expansion. Background Technology

[0002] Size-free bras utilize ultra-elastic fabrics and dot-matrix adhesive technology, allowing for a wider range of body shapes to be accommodated with fewer sizes, simplifying production and reducing inventory pressure for retailers. However, current size-free bras are primarily designed as tank tops for flat chests, which can feel constricting for women with fuller busts. If designed as a deep V-neck, the stretchy nature of the ultra-elastic fabric can cause the shoulder straps to stretch and lengthen, reducing the lift on the bust and widening the center gore, resulting in a more dispersed and outward-spreading bust shape, negatively impacting the wearing experience. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a deep V-shaped, size-free bra that improves breast shape by reducing outward spread and enhancing the wearing comfort of users with fuller busts.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A deep V-shaped, size-free bra for improving breast shape and reducing sagging, comprising: a front panel, a back panel, and shoulder straps; the two sides of the front panel are bonded to the two sides of the back panel by adhesive; the two ends of the shoulder straps are respectively fixed to the top of the tabs of the front panel and the back panel; the front panel includes an outer fabric and an inner fabric bonded by adhesive, and the two cups of the front panel form a deep V-shape; the tabs of the front panel are provided with non-elastic reinforcing pieces, which are bonded to the outer and inner fabrics of the front panel by adhesive; the center gore of the front panel is provided with micro-elastic reinforcing pieces, which are bonded to the outer and inner fabrics of the front panel by adhesive.

[0006] In some embodiments, the material of the non-elastic reinforcing sheet is non-elastic yarn.

[0007] In some embodiments, the material of the micro-elastic reinforcing sheet is an elastic fishing net or any cut net fabric.

[0008] In some embodiments, the back panel has a U-shaped notch at the top center, and the top surfaces on both sides of the U-shaped notch have a downward curvature. The shoulder straps are fixed to the top surfaces on both sides of the U-shaped notch.

[0009] In some embodiments, the top and bottom edges of the back garment piece are provided with elastic bands, which are glued to the inside of the back garment piece by dispensing adhesive.

[0010] In some embodiments, the outer and inner fabrics of the front garment piece, except at the cups, are bonded together by adhesive dots.

[0011] In some embodiments, the front panel has breast pads at the cups, sandwiched between the outer and inner fabrics.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0013] This invention relates to a deep V-shaped size-less bra that improves breast shape by eliminating the need for elastic reinforcement at the ear loops. This prevents the fabric at the ear loops from stretching during wear and reducing its lifting effect. The addition of a micro-elastic reinforcement at the center gore prevents the fabric at the center gore from widening during wear and causing the breast shape to spread outwards. This makes the deep V-shaped size-less bra more comfortable for users with fuller busts. Furthermore, the U-shaped notch and elastic band at the back panel make the back panel more stable during wear and less prone to riding up. Attached Figure Description

[0025] A preferred embodiment of this utility model is a deep V-shaped, size-free bra 100 designed to improve breast shape and prevent sagging. Figures 1-4As shown, the bra includes a front bodice 10, a back bodice 20, and shoulder straps 30. The two sides of the front bodice 10 are bonded to the two sides of the back bodice 20 by adhesive. The two ends of the shoulder straps 30 are fixed to the top of the tabs 11 of the front bodice 10 and the back bodice 20, respectively. The front bodice 10 includes an outer fabric and an inner fabric bonded by adhesive. The two cups 12 of the front bodice 10 are in a deep V-shape. The tabs 11 of the front bodice 10 are provided with non-elastic reinforcing pieces 13, which are bonded to the outer fabric and the inner fabric of the front bodice 10 by adhesive. The center gore 14 of the front bodice 10 is provided with micro-elastic reinforcing pieces 15, which are bonded to the outer fabric and the inner fabric of the front bodice 10 by adhesive.

[0026] In this embodiment, the non-elastic reinforcing piece 13 at the ear 11 can prevent the fabric at the ear 11 from being stretched and weakening the lifting force when wearing the bra; the micro-elastic reinforcing piece 15 at the center gore 14 can prevent the fabric at the center gore 14 from being stretched and causing the breast shape to expand outward when wearing the bra, which can make the deep V-shaped sizeless bra more comfortable for users with full bust.
