DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a highly elastic seamless cup applicable to a bra, a body suit, a dress with a cup, a swimsuit, and the like.

[0002]

2. Description of the Related Art Conventionally, bust parts such as brassieres have
In order to obtain good shape retention and appearance, or to prevent sewing elongation at the time of sewing, for example, a non-stretchable or almost non-stretchable surface material (for example, a half tricot fabric) and a polyurethane foam are laminated, and further, Cups thermoformed into a bowl shape are often used.

[0003]

However, in the case of the above-mentioned conventional cup, there is a disadvantage that the functionality of the cup is not sufficiently exhibited due to the presence of the non-stretchable outer material. That is, since the cup itself does not expand and contract with the delicate movement of the breast accompanying movement such as bending and stretching of the body, the cup itself cannot follow and respond quickly, and there is a disadvantage that the position of the cup shifts. In addition, since the breast is wrapped in a non-stretchable cup, the cup does not fit well into the breast, especially at the upper part of the cup, a gap may be formed between the cup and the breast, or it may bite into the skin on the upper part of the breast Therefore, there is a drawback that the wearing feeling is reduced. Therefore, the shape retention of a bust and a comfortable wearing feeling may not be fully exhibited.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention uses a stretch knitted fabric made of synthetic fiber, a polyurethane foam foam as an intermediate sheet material, and a highly absorbent and stretchable lining. A seamless brassiere, etc., characterized in that the outer material, the intermediate sheet material, and the lining are integrally thermocompression-bonded, and a cup is formed by thermoforming into a bowl shape. Offer cups. (Claim 1)

As described above, according to the first aspect of the present invention, a seamless cup having excellent elasticity and flexibility can be obtained, and the breast is completely contained in the cup and covered, so that the body can bend and stretch strongly. In such a case, the cup having elasticity with respect to the movement of the breast can quickly expand and contract to cope with the movement, so that the gap between the breast and the cup is prevented, and further, the lower part of the brassiere or the like can be prevented from rising. . In addition, the breast fits in a cup with elasticity, which gives a soft touch to the skin, and also has excellent shape retention and fit characteristics. The feeling of pressure is not felt, and a good touch is obtained, so that a bra and the like with an excellent wearing feeling can be obtained.

[0006] On the surface side of the outer material, a surface side fabric made of stretchable knitted fabric of synthetic fibers thermoformed into a bowl shape is provided by free polymerization. (Claim 2)

[0007] Since the front side fabric of the stretchable knitted fabric is provided on the front side of the outer fabric by superimposition, distortion of the cup displaced in response to the movement of the breast is blocked via the front side fabric. Since the movement of the cup does not directly affect the underwear or outer garment, a good appearance can be obtained when a bra or the like is worn. In addition, in the case of a cup having a four-layered structure in which a surface cloth is superimposed on a triple-laminated cup,
Compared with a cup in which dough is laminated four times, the overall flexibility of the cup is excellent and a smooth wearing feeling can be obtained.

3. The seamless cup according to claim 1, wherein the polyurethane foam as the intermediate sheet material has a density of 17 to 23 kg / m3. (Claim 3)

By setting the range of the density of the polyurethane foam as the intermediate sheet material to 17 to 23 kg / m 3, it is possible to obtain a good shape retention of the cup, a followability to the movement of the breast, and a moderate cup stiffness.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The contents of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment according to the present invention, in which 1 is a seamless cup formed in a bowl shape, 5 is a surface material made of synthetic fiber elastic knitted fabric (double-sided knitted fabric), and 6 is polyurethane. Intermediate sheet materials such as foam,
Reference numeral 7 denotes a lining made of a knitted fabric (plain knitted fabric) having excellent hygroscopicity and the like. Reference numeral 8 denotes a flat narrow portion provided on the lower peripheral portion of the seamless cup 1, and a sewing allowance portion for sewing a tape-like cloth or the like.

The method of manufacturing the seamless cup 1 is as follows. First, the synthetic fiber outer material 5, the intermediate sheet 6 made of polyurethane foam and the lining 7 are laminated one by one via a heating roller or the like. By thermocompression bonding, an appropriate laminate fabric can be obtained. Next, after cutting the laminated fabric into an appropriate shape, the laminated fabric is inserted between a pair of molds formed in, for example, concave and convex shapes by a known means, and subjected to thermoforming (molding). A bowl-shaped seamless cup 1 is obtained.

FIGS. 3 and 4 show a second embodiment according to the present invention. In the first embodiment, a seamless cup 11 is formed by providing a surface-side cloth 10 on the surface of the seamless cup 1 of the first embodiment. It is like that. The front side fabric 10 is thermoformed (molded) into a bowl shape in the same manner as described above, and then the peripheral portion of the thermoformed fabric 10 is sewn to the periphery of the seamless cup 1 as appropriate. A seamless cup 11 is obtained. FIG. 4 shows a brassier in which the second embodiment of the present invention is applied.
Is provided.

In the first and second embodiments, the outer material 5
As the material used for the front-side fabric 10, for example, a knitted fabric having a high elasticity such as a double-sided knitted fabric or a milled knitted fabric knitted with yarns of polyester-based or polyamide-based synthetic fibers is preferable. As long as the fabric is highly stretchable, it may be a synthetic fabric made of a warp knitted fabric such as a stretchable Russell knitted fabric that expands and contracts in the vertical and horizontal directions.

The intermediate sheet material 6 is preferably a stretchable sheet material such as polyurethane foam (for example, high-density polyurethane foam). Further, as the fabric used for the lining 7, knitted fabrics having a very high elasticity such as a plain knitted fabric, a milled knitted fabric, and a double-sided knitted fabric knitted with natural fibers such as cotton or human silk excellent in hygroscopicity and the like are used. However, as long as the fabric is highly stretchable and highly absorbent, it may be a warp knitted fabric such as a stretchable Russell knitted fabric that expands and contracts in the vertical and horizontal directions. In addition, Embodiments 1 to 1 of the present invention
The applicable range of the seamless cup in 2, for example, is a brassier, a body suit, a dress with a cup, a swimsuit, and the like. The density of the polyurethane foam ranges from 17 to 23 k.
When the density is less than 17 kg / m3 or more than 23 kg / m3, good cup shape retention and followability to breast movement and moderate cup waist may not be obtained. Yes, not preferred.

[0015]

As described above, the present invention uses a stretchable knitted fabric made of synthetic fibers, an intermediate sheet material made of polyurethane foam, and a lining made of a knitted fabric that is highly absorbent and stretchable. The intermediate sheet material and the lining were each integrally thermocompressed and thermoformed into a bowl to form a seamless cup such as a bra, or thermoformed into a bowl on the front side of the outer material of the seamless cup. By superimposing the fabric on the front side of the synthetic knitted elastic knitted fabric, a seamless cup with excellent elasticity and flexibility can be obtained, and the breast is completely contained in the cup and covered. This allows the cup, which can expand and contract with respect to the movement of the breast, to respond to sudden movements of the breast even when the body is intensely flexing and stretching, while preventing the cup from shifting or deforming. Is the more it is possible to prevent the shear-up of the lower portion of such brassiere. In addition, the breast fits inside the telescopic cup, which gives a soft touch to the skin, and has excellent shape retention, adhesion, and fit. This gives a good feel to the skin and gives a bra and the like with an excellent wearing feeling.
In addition, by disposing the front side fabric of a bowl-shaped thermoformed synthetic fabric on the front side of the outer material only by sewing around the periphery, distortion of the cup displaced in accordance with the movement of the breast causes the front side fabric to be distorted. Since the movement of the cup does not directly affect the underwear or the outer garment, the movement of the cup is less likely to affect the undergarment and the outer garment, and a smooth wearing feeling can be obtained by making the surface-side fabric seamless like the outer material.
