Abstract

PROBLEM TO BE SOLVED: To provide a bust pad having lightweightenss in spite of its thickness, having comfortable feeling to the skin, and having resilience as that of the human body, and excellent in shape or form retention. SOLUTION: This bust pad 1 is such as to be formed so as to have a two- layer structure wherein a low-hardness elastic layer 3 comprising a noncompressed foam or a foam with high expansion ratio is laminated on the inner surface of a high-hardness elastic layer 2 comprising a compressed foam or a foam with low expansion ratio.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bust pad to be attached to underwear such as brassiere, camisole, and clothes such as a dress with a cup.

[0002]

2. Description of the Related Art A bust pad to be attached to a brassiere or the like is generally formed of a thick nonwoven fabric or a relatively hard synthetic resin foam molded into a breast shape. Of these bust pads, those made of non-woven fabric have a good touch, but do not have sufficient shape retention, and are prone to shape loss and settling due to repeated attachment and detachment and washing, as well as elasticity like a human body. There is no. Also,
When the thickness is too large, the weight becomes heavy, and the wearer may feel discomfort such as stiff shoulders, and a large load is applied to the lower edge of the breast bulging portion of the clothes. On the other hand, a molded article made of a solid foam has a good shape-retaining property, but it is hardly adapted to the skin and gives a sense of incongruity.

[0003] Therefore, for the purpose of preventing shape loss and settling, and improving the feeling of wearing, a two-layer structure having a shape-retaining material made of thin polyurethane foam on the outside and a good-sensitive material made of thick nonwoven fabric on the inside. Japanese Unexamined Patent Application Publication No. 10-1980 discloses a padded garment having a pad formed in an integral structure.
No. 8105. However, in this case, although a polyurethane foam having a shape-retaining property is laminated on the outer side, if the inner non-woven fabric layer loses its shape, the outer layer may be cracked and the whole may be deformed. Further, if the thickness of the nonwoven fabric is increased in order to enhance the body shape correction effect, the weight tends to increase and the elasticity is not sufficient.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a bust pad which has a good touch, is excellent in shape retention, has elasticity like that of a human body, and is lightweight even if it is thick. As an issue.

[0005]

A bust pad according to the present invention is constructed by laminating a low hardness elastic layer on the inner surface of a high hardness elastic layer. The relatively hard high hardness elastic layer forms a beautiful bust line with good shape retention and the soft low hardness elastic layer is easy to adapt to the skin and has a good feeling of wearing. Also, since both layers are elastic layers, sufficient elasticity can be obtained. A foam can be used for the high hardness elastic layer and the low hardness elastic layer. Examples of the foam include a soft vinyl chloride foam and a foamed polyurethane. With this configuration, even if the wall thickness is large, the weight can be reduced, and settling due to lapse of time can be prevented. The high hardness elastic layer can be composed of a compressed foam or a foam having a low expansion ratio, and the low hardness elastic layer can be composed of a non-compressed foam or a foam having a high expansion ratio.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail based on the ground. As shown in FIGS. 1 and 2,
The bust pad 1 of the present invention has a low-hardness elastic layer 3 laminated on the inner surface of the high-hardness elastic layer 2 and the outer and inner surfaces thereof are covered with cloths 4 and 4, respectively, and molded into a cup shape so as to fit into the breast. I have. The high hardness elastic layer 2 is made of a compressed foam obtained by compressing a foamed polyurethane foamed at an arbitrary expansion ratio, a soft vinyl chloride foam, or the like to a thickness of about 1/2,
It has a thickness of about 2 to 4 mm in order to obtain sufficient shape retention. The low-hardness elastic layer 3 is made of an uncompressed foam such as a foamed polyurethane or a soft vinyl chloride foam expanded at an arbitrary expansion ratio.
It has a thickness of about 3 to 10 mm which is thicker.

The hardness of the high hardness elastic layer 2 and the hardness of the low hardness elastic layer 3 can be varied by changing the expansion ratio. That is, the high hardness elastic layer 2 is formed of a foam having a low expansion ratio, and the low hardness elastic layer 3 is formed of a foam having a higher expansion ratio than the high hardness elastic layer 2. The thickness of the high hardness elastic layer 2 is preferably changed depending on the expansion ratio of the low hardness elastic layer 3. When the expansion ratio of the low hardness elastic layer 3 is high and soft, the high hardness elastic layer 2 is thickened. If the hardness elastic layer 3 has a low expansion ratio and is hardened, the high hardness elastic layer 2 may be thinned. The cloth 4 is preferably a thin and soft material such as a tricot such as a polyester tricot or a nylon tricot, a cotton mixed flat knitted fabric, or a sheet of cotton. The high-hardness elastic layer 2, the low-hardness elastic layer 3, and the cloth 4 on the inner and outer surfaces are laminated by interposing a heat-sensitive adhesive between the layers and heating at a low temperature at which the adhesive acts.

In order to form the bust pad 1, the laminated material is cut into an appropriate size and then molded by heating and pressing between a male mold and a female mold, or
This is performed by a so-called cut and saw that sews a plurality of members cut into an appropriate shape. The heating conditions and the pressing conditions during molding are set so that the elasticity of the low hardness elastic layer 3, particularly the elasticity of the central portion thereof, does not decrease. When the molded bust pad 1 is a pad for brassiere, as shown in FIG. 3, its outer surface is covered with a surface cloth 6 such as a lace ground and sewn, and a back strap 8, a shoulder strap 9, etc. To form the brassiere 5.

Since the bust pad 1 is covered with the cloth 4, the bust pad 1 can be removably stored in a bag provided on the inner surface of the bra without being sewn into the bra.
In this case, it is desirable to cover the cut edge of the bust pad 1 with a band cloth of the same material as the cloth 4, or to overlock with a wooly thread or the like. In addition, the bust pad can be attached to underwear such as a camisole, or a garment such as a swimsuit or a dress with a cup.

[0010]

According to the first aspect of the present invention, since it is formed of two elastic layers, it has a high elasticity like a human body and does not have any intentionalness. In addition, the inner layer that hits the skin is made of a soft low-hardness elastic layer, so it fits well into the chest and feels good. At the same time, the durability is good, and the mold is not easily broken or damaged. According to the inventions according to Claims 2 to 4, the deformation due to the passage of time can be more reliably prevented, and even if the wall thickness is increased in order to enhance the bust correction effect, the weight can be reduced, so that the feeling of wearing deteriorates and the wear is reduced. Increase in the burden on the user.
