TECHNICAL FIELD The present invention relates to a fastener for brassiere, a method for manufacturing the same, and a brassiere using the same. Here, "bras" are women's clothing having at least a cup and strap left and right ends, and include a brassiere, a swimsuit, a lingerie, and a corset. In the following description, a brassiere will be described as an example.

[0002]

2. Description of the Related Art Bra fasteners are provided on left and right strap ends on the back side or front side of a wearer, and are fixed to the wearer by engaging them with each other. The length of the strap end is usually adjustable in several steps according to the size of the wearer.

The most common type of fastener is the hook and eyelet type. Since this conventional fastener is often made of metal, (1) it is easy to make a snag on other clothes, (2) it is easily damaged during washing, and (3) it is colored in the same color as other parts. It has the drawback of being difficult to do.

In view of this, Japanese Patent Laid-Open No. 2001-178507 proposes that this fastener is a snap button made of plastic, and that it is made from a snap fastener with a tape.

[0005]

However, Japanese Patent Laid-Open No. 2001-2001
Since the snap button used in the invention of -178507 has a base portion for both the male and female buttons, there is a disadvantage that the thickness becomes thick when they are engaged with each other.

The present invention is also basically disclosed in Japanese Patent Laid-Open No. 2001-17.
Although inheriting the idea of 8507, it is intended to provide a brassiere fastener having the following features. (1) By improving the snap buttons used,
Even when the male and female buttons are engaged, the thickness is thinner than the conventional one. (2) The strength is generally increased to make it durable.

The present invention also provides a method for manufacturing such a fastener for brassiere and a brassiere using the same.

[0008]

The first invention of the present application is a left and right fastener attached to the left and right ends of straps of brassieres, wherein the male fastener is at least one row and at least one composite fastener per row. There are at least one row of male side tape pieces formed by molding and fixing the male side snap buttons made of resin on the male side fabric tape, and at least one row of female side snap buttons made of synthetic resin per row. The male side snap button is formed by directly fixing the engaging projections directly from the dough tape without the base. And

The second invention of the present application is a method for manufacturing left and right fasteners attached to the left and right ends of straps of brassieres, and there are a plurality of rows, and at least one male snap button made of synthetic resin per row is molded and fixed. At least one row of pieces is cut out from the male side fabric tape to be a male side fastener, and there are a plurality of rows, and at least one female side fabric tape formed by molding and fixing at least one synthetic resin female snap button per row A female tape piece in a row is cut out to form a female fastener, wherein the male snap button is one in which an engaging protrusion is directly raised from a cloth tape without using a base. The feature is that the tool is attached to the left and right ends of the brassiere strap.

A third invention of the present application is a brassiere having the above-mentioned brassiere fastener.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Ultrasonic welding is sufficient for the upper and lower end portions (tape cut portions) of the male side tape piece and the female side tape piece, but the free end portion and the vicinity of the snap button are sutured together to increase strength. Preferably.

For the same purpose, it is preferable to provide a reinforcing base cloth on the lower side of the male side tape piece and the female side tape piece.

It is aesthetically preferable that the external appearance of the male side snap button and the female side snap button is ring-shaped when viewed from the front and the back. Since a non-perforated tape is used, the tape is exposed in the center of the ring.

When molding the male snap button, a non-perforated dough tape having a roughness that allows the molten resin to pass therethrough by the molding pressure is disposed between the upper and lower molds forming the fastener molding space. Male tape snap button formed on both sides of the fabric tape by sandwiching and fixing the fabric tape of the recess located inside the engagement protrusion of the side snap button with the upper and lower molds and then injecting synthetic resin into the molding space. It is preferable that the front surface side and the back surface side of the are integrated with a synthetic resin that penetrates the cloth tape.

When molding the female side snap button, a non-perforated dough tape having a roughness through which the molten resin permeates by the molding pressure is disposed between the upper and lower molds forming the fastener molding space. The cloth tape of the engaging recessed portion of the side snap button is sandwiched and fixed by the upper and lower molds, and then a synthetic resin is injected into the molding space to form the front surface side of the male snap button formed on both surfaces of the cloth tape. It is preferable to integrate the back surface side with a synthetic resin that penetrates the cloth tape.

A left side fastener 5 is attached to the left side end 1 of FIG.
And two female snap buttons 4 are provided in two rows. A right side fastener 7 is provided at the right side end portion 3 of FIG. 1B, and two male snap buttons 6 are provided. Male and female snap buttons for left and right fasteners 4,
By engaging 6 the left and right brassiere strap ends 1, 3 are joined together. This joint is often on the back side, but may be on the front side.

The snap buttons 4, 6 used in the present invention and the manufacturing method thereof will be described with reference to FIGS. Figure 3
Is a fastener with tape 2 that is the raw material for snap buttons
FIG. 4 is a plan view of the same as seen from the joining surface side, (a) is a tape 30 on the female snap button 4 side, and (b) is a tape 18 on the male snap button 6 side. Each snap button 4, 6 has a substantially ring-shaped appearance. The opposite side of each snap button is not shown, but each has a ring-shaped appearance. However, the width of the ring on the opposite side becomes slightly thicker for the reason of molding described later.

Both ends of the female tape 30 are folded back and used at the snap button position so as to be doubled. The male tape 18 is also folded back on both sides, and is doubled at the snap button position. Neither tape has holes for snap button attachment. This is not necessary, as will be described later.

FIG. 4 is a plan view of the male snap button 6, and FIG. 5 is a sectional view. Unlike the conventional male snap button, this snap button 6 has substantially no base near the cloth tape as shown in FIG. In the drawing, the joint surface with the cloth tape 18 is slightly swelled, but such a bulge is not considered as the base, and it can be almost completely eliminated depending on the design.

The engaging projection 20 of the male side snap button is
A bulging edge 22 for engagement and a concave portion 24 for expansion / contraction deformation by resin elasticity are provided around the tip portion.

In order to mold this male side snap button 6, a hole is formed between the upper and lower molds (not shown) in which the fastener molding space is formed, the roughness of which allows the molten resin to pass therethrough by the molding pressure. Place the dough tape 18 not
The material tape of the recessed portion 28 located inside the engagement protrusion 20 is sandwiched and fixed by the upper and lower molds, and then the synthetic resin is injected into the molding space. The small indentation 26 in FIG. 5 corresponds to the injection port of the mold. Due to this setting of the injection port, the ring width viewed from the back side is slightly wider than the width of the engagement protrusion 20 (that is, the ring width viewed from the front side).

In this manner, the front surface side and the back surface side of the male side snap buttons formed on both surfaces of the material tape 18 are integrated by the synthetic resin that penetrates the material tape 18.
In this fastener-side snap button, as described above, the material tape located in the recessed portion 28 located inside the engagement protrusion 20 is fixed by being sandwiched between the upper and lower molds, so that the material exposed to high injection pressure is exposed. The area of the tape is smaller than that of the prior art. Therefore, the tape is hardly distorted or wavy due to the injection pressure at the time of molding, and is almost eliminated. As a result, it is possible to avoid the situation where the tape is exposed from the surface of the synthetic resin, the strength of the fastener is reduced, and the appearance is spoiled.

The tape material 18 needs to be a material through which the molten resin can permeate without being melted, and may be a woven material or a knitted material. For example, a cotton material, a blended material or the like can be used. As the synthetic resin, a thermoplastic resin,
For example, polyacetal molten resin can be used.

FIG. 6 is a plan view of the female side snap button 4, and FIG. 7 is a sectional view. The cloth tape 30 is scissored to form the engaging recess 32 made of synthetic resin. The engaging recess 32 of the female side snap button has an engaging edge 34 formed inside the opening so as to allow die cutting.

The method for molding the female side snap button is almost the same as that for the male side snap button 6, and therefore detailed description thereof is omitted. The small indentation 36 in FIG. 7 is the resin injection port.

FIG. 8 shows a cross section of the state where the male snap button 6 and the female snap button 4 of the present invention are engaged. It can be considered as an enlarged view of the engaged state of the male and female snap buttons in the brassiere fastener.

In the present invention, the female side tape 30 and the male side tape 18 are replaced with the taped snap fastener 2 of FIG.
Cut with a dash-dot line from and use it as a brassiere fastener. However, simply sewn this to a brassiere strap is weak in strength, so the strength is increased as follows.

In the left side fastener 5 having the female side snap button 4, as shown in FIG. 2A, a base cloth 9 made of a non-woven fabric is provided on the lower portion (on the wearer side). Both ends of the base cloth are folded back to form double layers 9a and 9b. On the base cloth 9, the female tape piece 30a having the female snap button 4 is placed. The base cloth 9 is formed to be slightly longer than the female tape piece 30a, and the intermediate cloth 11 is sewn to make the length uniform.
It is connected to the.

In the above state, the upper and lower end portions 13 and 15 (see FIG.
(See (a)) is ultrasonically welded. The free end portion 17 may also be ultrasonically welded, but stitching is preferable because this portion requires particularly high strength. 2 to increase strength

In order to join the left-hand side fastener 5 and the left-hand side brassiere strap left end portion 1, the left-hand side brassiere strap left-end portion 1 is sandwiched between the base cloth 9 and the intermediate cloth 11 of the fastener,
Both ends 21 and 23 of the intermediate cloth 11 are fixed by sewing.

In the right side fastener 7 having the male side snap button 6, as shown in FIG. 2B, a triple base cloth 25 is provided on the lower portion (on the wearer side). This is because both ends of the base cloth are folded back into double layers 25a and 25b, and the core material 25c is inserted between them. On the base cloth 25, the male tape piece 18a having the male snap button 6 is placed.

In the above state, the upper and lower end portions 27 and 29 (see FIG.
(See (b)) is ultrasonically welded. The free end portion 31 may also be ultrasonically welded, but stitching is preferable because this portion requires particularly high strength. To further increase the strength, stitching is also performed around the snap button 33.

In order to join the right side fastener 7 and the right brassiere strap right end portion 3 to each other, the right brassiere strap right end portion 3 is joined to the fastener base cloth 25 and the male tape piece 18a.
And the position 35 is fixed by suture.
