## Title
Bra pad

## Abstract

A bra pad is combined selectively from thermoplastic polyurethane (TPU) films, silicone gel material or silicone gel material layers, lightweight material layers and cloth layers. The TPU films are configured for containing the silicone gel material to make the silicone gel material layer form a concave cup. A space defined in the concave cup is configured for combining the lightweight material layer. The lightweight material layer has an opposite side surface attaching to the cloth layer to form the bra pad. The present bra pad employs the silicone gel material layer to make it have excellent tactility and comfortable, and employs the lightweight material layer to decrease the weight. Furthermore, the cloth layer is configured for increase the breathe capability and the heat-dissipating capability to make the users more comfortable and no burthen when being carried for a long time or in sports.

## Background
FIELD OF THE INVENTION
The present invention relates to bra pads, and more specifically, to a bra pad made of a combination combined selectively from materials selected from a group consisting of thermoplastic polyurethane (TPU) films, silicone gel layers, lightweight material layers and cloth layers, and having functions with light weight, excellent tactility and velvet, good breathe capability and heat-dissipating capability.
DESCRIPTION OF THE RELATED ART
A conventional bra pad is manufactured by filling liquid-state silicone gel into a chamber formed by a TPU film, and further by solidifying the liquid-state silicone gel. The conventional bra pad may be used for users by cooperating with a bra. The conventional bra pad is a finished product, however, the conventional bra pad has some disadvantages described as following:
1. The conventional bra pad is entirely made of silicone gel, thus it is very weighty, and tends to increase load of the users.
2. Since the conventional bra pad is very weighty, when the users carry the conventional bra pad for a long time or in sport, sweat or heat generated from the users cannot be dissipated effectively, thus the breathe capability and the heat-dissipating capability thereof is bad. Therefore, the conventional bra pad is not favored by the users.
To solve the above problems, another conventional bra pad is manufactured by adding vesicant into the liquid-state silicone gel to decrease the weight of the conventional bra pad. However, since the specific gravity of the vesicant is less than 1, the vesicant tends to float in the silicone gel and congregate together. Thus the vesicant is distributed nonuniformly. The conventional bra pad has a bad tactility and handle, and the conventional bra pad is nonuniform, therefore, it affects greatly the comfort thereof.
The inventors of the present invention invent a bra pad through working experience and larger investigation for solving the above problems.
What is needed is a bra pad which can solve the above problems.
BRIEF SUMMARY
An object of the present invention is providing a bra pad, which can decrease the whole weight thereof, to remain a dry and comfortable state when the users carry the bra pad of the present invention for a long time or in sports.
Another object of the present invention is providing a bra pad, which can enhance the soft comfortable capability, and have an excellent handle. Furthermore, the bra pad of the present invention can make the whole cup elasticity, specific gravity, and active feeling thereof fit with the skin of people, to make the users more comfortable.
The bra pad in accordance with a preferred embodiment of the present invention, is made from combining selectively from materials selected from a group consisting of TPU films, silicone gel material or silicone gel material layers, lightweight material layers and cloth layers. The TPU films are configured for containing the silicone gel material to make the silicone gel material layer form a concave cup. A space defined in the concave cup is configured for combining the lightweight material layer. The lightweight material layer has another opposite side surface attaching to the cloth layer to form the bra pad. The present bra pad employs the silicone gel material layer to make it have excellent tactility and comfortable, and employs the lightweight material layer to decrease the weight thereof. Furthermore, the cloth layer is configured for increase the breathe capability and the heat-dissipating capability to make the users more comfortable and no burthen when being carried for a long time or in sports.
