Description

  The present invention relates to an improvement of a brassiere.

In order to improve the wearing feeling of the bra that covers the breasts of women and to prevent the clothes (blown and shirt silhouettes) worn on it from being worn when worn as underwear, to further simplify the manufacturing process, Various non-sewn (seamless) brassieres have been proposed (Patent Documents 1 to 6).
These are formed with a stretchable outer and lining in one piece of fabric (sheet-like body), and a non-stretchable cup core material is placed between both fabrics, by heat molding and high frequency processing, The part corresponding to the breast (cup part) is three-dimensionally and integrally formed with the side belt part (the part provided on the left and right sides of the cup part, which is turned to the back when used and the tips are locked together). The outer surface and the lining are bonded with an adhesive by a molding press or the like, thereby eliminating the formation of the cup portion by conventional draping, the sewing of the cup portion and the side belt portion, the outer surface and the lining.
This eliminates the seams (stitches) generated by draping up to now and stitching of the outer and lining, and eliminates the overlap of the fabric, improving the above feeling of wearing, and to the clothes worn on top The effect is eliminated, and the complicated sewing process is not required in the manufacturing process.

JP 2004-263315 A Utility Model Registration No. 3080719 Utility Model Registration No. 3086998 Japanese Utility Model Publication No. 50-98321 No. 8-322 JP 2001-73203 A

However, with the above-mentioned integral molding, there is room for further improvement in terms of improving the wearing feeling even if sewing by draping the cup part, sewing the outer and lining, and the cup part and the side belt part. The inventor of the present invention thought.
Specifically, the body surface is curved from the front side to the body side, but it is not sufficient to eliminate the feeling of pressure of the side belt part that abuts against this part. There was nothing that considered a sense of incongruity that the corner (edge) generated between the side belt part hits. Further, if a separate chest pad or wire is inserted into the cup portion, a step difference is produced between these members and other parts of the brassiere, which further causes a sense of incongruity. In any of the above-mentioned patent documents, those that have been sufficiently studied are not shown.

  For example, in the above-described Patent Document 6, for improving the feel of the cup part itself, a device using urethane foam as an intermediate sheet material has been devised. No ingenuity has been made to eliminate the uncomfortable feeling between the body and the uncomfortable feeling caused by the chest pad or wire. Other patent documents also relied on the material of the outer and lining materials, eliminating the sewing by bonding and integral molding, eliminating the seam and fabric stitching, and the above problems of pressure and discomfort. There is nothing to fully consider.

  The present invention devised a feeling of pressure by the above side belt part, in particular, a sense of incongruity due to the angle generated between the three-dimensional cup part and the flat side belt, and further, the use of a chest pad or a wire between these members and the brassiere. It is an object to eliminate the uncomfortable feeling that occurs between other parts.

By this, the feeling of pressure at the time of use by said side belt part, especially the discomfort by the angle | corner which arises between the cup shape | molded in three dimensions as a finished product and a planar side belt were suppressed.
Both the outer material and the lining material are formed from the same material from the cup part to the side belt part. The soft feeling (feel) is constant (no bias). In particular, the side belt portion is also provided with a cushion material continuously from the cup portion as described above, and the soft feeling is constant.
Also, by eliminating sewing by bonding, complicated sewing processes can be eliminated, manufacturing equipment can be simplified, and the danger of damaging the user's skin due to the inclusion of broken sewing needles has been completely eliminated. . As a result, consumers can wear a brassiere that directly touches the skin, and the manufacturer can eliminate the root of the biggest complaints of the past without having to pass through a number of meter reading devices. It was.
Further, by shortening the manufacturing process and simplifying the members, it is possible to provide consumers with quick products at low cost.
Usually, a brassiere is a composite of various materials, but in the present invention, the members and sewing can be simplified as much as possible. In other words, the front and back are each formed of one piece of fabric, and a continuous cushion material is arranged between the front and back fabrics, and both the fabric and continuous cushion material are integrated, and the number of components is small. In addition to the above-described simplification of the manufacturing process, the cost of the components can also be suppressed.
In addition, the cup and side belt are made of a single piece of cloth for the outer and lining, so that the entire brassiere is integrated into a plain surface, so that the brassiere is part of the body line. Even if you wear clothes of thin fabric, you can express a natural body line without attrition.

In the second device of the present application, the outer material and the lining material are formed of synthetic fibers having thermoformability, and by adopting soft urethane foam or non-woven fabric for the above-mentioned continuous cushion material, the three-dimensional cup portion is formed. Wrinkles are less likely to occur and a soft fit that fits the body has been achieved.
As described above, by forming the continuous cushion material with a soft urethane foam or non-woven fabric, that is, by providing the soft urethane foam or non-woven fabric in a band shape (continuous) between the outer material and the lining material, the tightening force on the body and chest is increased. A soft feeling that disperses and wraps around the body and chest is obtained. Conventionally, polyurethane foam was used only for the cup part. Thus, by continuously providing polyurethane foam (soft urethane foam) or non-woven cloth up to the side belt part, It is soft and fit.
In addition, by forming the outer material and the lining with synthetic fiber having thermoformability, the outer material, the lining material and the continuous cushion material are more reliably integrated with the thermoforming press using the adhesive, and the entire brassiere Can be shaped at once. That is, the thermoforming press allows the bra cup to be swelled (three-dimensionally), and heats the adhesive to bond the outer material and the lining material. Therefore, the entire brassiere (main part) can be completed at once by integral thermoforming.

  In the third and fourth inventions of the present application, those that employ the cup cushion material do not give the user a sense of incongruity between the cup cushion material and other parts of the brassiere.

In the fifth device of the present application, in the third device of the present application, the continuous cushion material is bonded to the entire inner surface of at least one of the outer material and the lining material, and is layered integrally with the outer material or the lining material. By providing the continuous cushioning material, the cushioning property of the cushioning material can be given more evenly to the body, and the feeling of wearing can be further improved.
Both the cushion material for cups and the continuous cushion material are made of flexible urethane foam with excellent elasticity. Especially, the soft urethane foam that forms continuous cushion materials is soft that forms the cushion material for cups. By making the density lower than that of the urethane foam, the uncomfortable feeling due to the arrangement of the cushion material for the cup was alleviated and the feeling of wearing was extremely high.

  In the sixth device of the present application, in the fifth device of the present application, by setting the density of the continuous cushion material and the cushion material for the cup as described above, the wearing feeling is further improved. Provided a brassiere that was not easily wrinkled or deformed.

  In the seventh device of the present application, the continuous cushioning material is provided on the inner side of the outer surface and the inner side of the lining material, so that the continuous cushioning material has two layers, and the cushioning material for the cap is sandwiched between both layers. Thus, the above-mentioned uncomfortable feeling caused by the cup cushion material is surely eliminated, and the wearing feeling is optimized.

  In the eighth aspect of the present application, after the cushioning material for the cup is provided in an overlapping manner between the two continuous cushion materials, before the integral molding by the thermoforming press of the outer and the back and front and back continuous cushion materials, Since the brassiere is shaped by a thermoforming press, the shape of the breast can be adjusted to a higher volume.

  In the ninth device of the present application, the breast position can be adjusted by inserting the above aggregate together with the cushion material for the cup before the thermoforming press and between the cup portion of the outer material and the lining material. Also, with such an aggregate, as described above, the uncomfortable feeling generated between the aggregate and the other part of the brassiere was suppressed by the continuous cushioning material on the outer surface and the inner side of the lining. Further, the position of the cup portion was made more stable by preventing the extension. That is, the extension from the cup portion (for the right breast) and the cup portion (for the left breast) stops the force from the side belt portion due to the wearing of the brassiere, thereby preventing distortion of the entire cup portion.

The outer surface 11 is formed of a single piece of synthetic fiber having thermoformability, and the cup portions 11a and 11a and the side belt portions 11b and 11b are integrated with each other.
A synthetic fiber having stretchability (stretchability) is employed as the above-described synthetic fiber having thermoformability. In particular, it is preferable to employ polyurethane elastic fiber as the synthetic fiber having thermoformability. In addition, for example, ester-based synthetic fiber can be employed. Stretchability can be obtained by twisting the fiber as usual.
The polyurethane elastic fiber is usually called a two-way tricot or spandex.

Similarly, the lining 12 includes cup portions 12a and 12a constituting the back side of the cups 1a and 1a, and side belt portions 12b and 12b constituting the back of the side belts 1b and 1b.
