Description

Molded cup and manufacturing method thereof

Technical field

The present invention relates to the technical field of bra design, and more specifically, to a molded cup and a manufacturing method thereof.

Background technique

As a common underwear for women, the bra has the functions of supporting, protecting and beautifying female breasts. The earliest origin of the bra is a very tight corset popularly worn by European aristocrats in the Middle Ages. Later, because the corset was too troublesome, it was changed. Two handkerchiefs were used to make a bra, which became the prototype of a modern bra.

Existing bras are usually composed of chest, shoulder and back positions, and their structure can be roughly divided into: hook buckle, back strap, shoulder strap, loop buckle, buckle, upper strap, upper bowl, lower bowl, ears, Front panel, chicken heart, side ratio, rubber bone, back ratio, bottom steak, bottom bundle, steel ring and coaster.

Because most of the female breast is fatty tissue, there are some ligaments and skin to provide internal support. However, these supports are sometimes not enough to support the breasts, which can easily lead to breast sagging. The main function of the bra is to provide external support to the breast. The bra bears the gravity of the breast, protects the breast from the gravity traction and droops, and increases the comfort and mobility of the breast. A good breast must not only be able to firmly support the lower part of the breast and limit the downward movement of the breast, but also relax the skin of the breast and provide sufficient comfort for the breast.

But the bras on the market are either not tight enough or not breathable enough. Wearing a bra that is too tight will often cause pressure marks on the chest. If the chest is compressed for a long time, it will cause the circulation of Qi and blood to be blocked, and breast diseases are prone to occur, which will affect the health of the breast. However, if you wear a bra that is too loose, it will be difficult to support the breasts. Over time, the breasts will droop, which will not serve the original role of the cup. In addition, the left and right yards of the bra cup core are usually set symmetrically. However, the human body may cause inconsistencies in the shape and size of the left and right breasts due to the beating of the heart and the work measurement of the left and right hands, which affects the comfort of wearing the bra.

technical problem

The present invention aims to overcome at least one of the above-mentioned defects of the prior art, and provides a molded cup and a manufacturing method thereof. By filling the cup with ventilated fluffy material, the volume of the cup is increased, the movement space of the cup is increased, and the breast can be both Get good breathing, avoid being oppressed, and keep your breasts comfortable.
