1. Field of the Invention
The present invention relates to a pressable air cushion of a bra cup, more particularly one, which can be inflated and bled; the cup can be in such a shape as to cover a whole breast, a half or three-fourths of a breast; the air cushion has an elastic plate with a recess portion; the recess portion can face a first direction to allow the cushion to be inflated, and which can face an opposite direction to allow the cushion to be bled.
2. Brief Description of the Prior Art
Certain functional brassiere cups can lift, enlarge and massage the wearers' breasts and make them look perky. Such cups usually contain pads, air cushions or water bags.
The inventor of the present invention developed a brassiere cup, and filed a patent application based on this invention in Taiwan; the cup consists of inner and outer cotton layers, inner and outer foam layers, and an air cushion; the inner and the outer foam layers are positioned between the inner and the outer cotton layers, and the air cushion is completely covered with the inner and the outer foam layers. The air cushion consists of an inner plastic film, a short plastic film, and an outer plastic film, which are joined together by means of heat-sealing. A holding room is formed between the inner and the short plastic films, and there is an air passage communicating with the holding room. The air cushion includes a pressed component, which is held in the holding room. The inner plastic film has an air inlet, which faces the pressed component, and which is exposed through a through hole formed between the inner foam layer and the inner cotton layer. A waterproof film extends from the inner cotton layer to cover the through hole. The cup is found to have a drawback: after the cup is put on the wearer's breast, it will form raised lines on its surface to become unpleasant-looking if the air cushion is over-inflated. Consequently, the bra will spoil the contour of the wearer's breast.
Therefore, it is a main object of the present invention to provide an improvement on a brassiere cup to overcome the above problem.
A pressable air cushion of a brassiere cup in accordance with an embodiment of the present invention consists of first and second plastic films, an elastic plate, a pressed component, and a short plastic film. The first plastic film has an air inlet hole; the first and the second plastic films are stuck together at their peripheries to form an air room. The elastic plate is interposed between the first and the second plastic films, and has a recess portion capable of being moved to change direction; the elastic plate is joined at one end to the first plastic film with a flow guiding passage being formed between the elastic plate and the first plastic film to allow air to flow into the air room. The pressed component is interposed between the air inlet hole of the first plastic film and the recess portion of the elastic plate. The short plastic film and the elastic plate are stuck together at their peripheries with an air outlet hole being formed therebetween; the short plastic film has a through hole facing the recess portion of the elastic plate.
The present invention will be better understood by referring to the accompanying drawings, wherein:
Referring to
an inner and an outer cotton layers 1 and 2; the inner cotton layer 1 has a through hole 11;
an inner and an outer foam layers 3 and 4 positioned between the inner and the outer cotton layers 1 and 2; the inner foam layer 3 has a through hole 31, which faces the through hole 11 of the inner cotton layer 1; and
a pressable air cushion 5, which can be inflated and bled; the pressable air cushion 5 is positioned between and completely covered with the inner and the outer foam layers 3 and 4.
The pressable air cushion 5 consists of:
a first plastic film 51; the first plastic film 51 has an air inlet hole 511, which is exposed through the through holes 11 and 31 of the inner cotton layer and the inner foam layer 1 and 3;
a second plastic film 52; the first and the second plastic films 51 and 52 are stuck together at peripheries thereof so that an air room 521 is formed between the first and the second plastic films 51 and 52;
an elastic plate 53 interposed between the first and the second plastic films 51 and 52; the elastic plate 53 has a recess portion 531, which can change in direction; the elastic plate 53 is joined at a first end thereof to the first plastic film 51 by heat-sealing so that an air guiding passage 532 is formed between the elastic plate 53 and the first plastic film 51 to allow air to flow into the air room 521 therethrough;
a pressed component 54 interposed between the air inlet hole 511 of the first plastic film 51 and the recess portion 531 of the elastic plate 53; the pressed component 54 is elastic and resilient, and it can be a sponge, a piece of foam, foaming object, rubber or elastic fibers; and
a short plastic film 55; the short plastic film 55 is larger than the elastic plate 53; the short plastic film 55 and the elastic plate 53 are stuck together at peripheries thereof with an air outlet hole 551 being formed between first ends thereof; the short plastic film 55 has a through hole 552 facing the recess portion 531 of the elastic plate 53.
The cup (A) can be in such a shape as to cover a whole breast, a half or three-fourths of a breast. Referring to
To inflate the air cushion 5, referring
Air can be forced to flow out of the air cushion 5 when the air cushion 5 contains too much air. Referring to
From the above description, it can be seen that the brassiere cup of the present invention has the following advantages:
1. The cup can lift the wearer's breast, and make it look perky because it has the air cushion.
2. The air cushion held in the cup can be inflated by means of repeatedly squeezing the air cushion. Therefore, one can easily make the air cushion contain sufficient amount of air to lift her breast and make it look perky when she is wearing the bra.
3. Air can be forced to flow out of the air cushion when the air cushion contains too much air or before the user washes the bra. Therefore, the bra of the present invention has a smoothly curved shape, not having the same drawback as the prior art, which can't be bled, and will form raised lines on its surface to spoil the contour of the wearer's breast if its air cushion is over-inflated.
