Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape-attached synthetic resin attachment / detachment for use in clothing such as foundations for brassieres and body suits, innerwear and sports clothing, outerwear and the like, and a method for producing the same.

[0002]

2. Description of the Related Art Various kinds of attachments / detachments (buttons, metal snap buttons, fasteners, tape nappers, gripper tapes, etc.) are used for clothing such as women's innerwear, foundations, and outerwear, depending on their use and function. However, these attachments / detachments require the following characteristics.

By being able to withstand external stresses associated with expansion and contraction of clothes due to changes in the body surface during exercise when worn, being safe when worn, being easy to put on and take off, and being able to be repeatedly used However, the function does not deteriorate, and the attachment / detachment itself is used for clothing and is the same as the surroundings, so that there is no discomfort.

Among the above-mentioned attaching / detaching tools, recently, a gripper tape (trade name) in which a snap button is enlarged and a tape napper (trade name) in which a metal snap button is made into resin have been widely used.

Further, in the manufacturing method thereof, as shown in FIG. 4, the upper and lower molds 10 and 1 are formed with molding recesses 10a and 11a for forming male or female attaching and detaching tools.
A cloth tape 3 having a small hole 3a formed at the center thereof is inserted between the two and the small hole 3a is interposed so as to be the center of the molding recesses 10a, 11a.
A method has been adopted in which the cloth tape 3 is sandwiched between 2, 12, 13 and 13, the molten resin is injected to fill the molding recesses 10a and 11a with the resin, the resin is cured, and then the mold is released.

[0006]

However, in the case of the gripper tape, instead of sewing, the metal rivet structure is used to sandwich the tape from above and below to attach the attaching / detaching tool. Since the mounting is a rivet structure, when the sandwiching position shifts from both sides of the tape in the manufacturing process, the metal rivet ring may be turned up and the protrusion may occur, which may damage the wearer's skin. Further, there is a problem that the fixing force due to fatigue of the internal spring becomes weaker during repeated use.

Further, in the case of the tape napper, since the force of fitting and elasticity of the resin are used instead of the spring of the metal snap button as a fixing structure, abrasion due to friction at the time of attachment / detachment causes the attachment / detachment. A decrease in the fixing force, which occurs at right angles to the tool pulling direction, was unavoidable.

Further, as shown in FIGS.
When the male button 1 and the female button 2 are fitted, the fulcrums a, a in the pulling direction and the contact point b of the fitting portion do not coincide with each other on a straight line, and therefore when a lateral pulling force is applied from both sides, the fitting portion is slanted. There is a problem that a force is applied and a rotational moment is generated in the fitting portion, a force for releasing the engagement works, and it is extremely weak against the pulling force.

Also in the manufacturing method, since the small hole 3a is preliminarily formed in the center of the cloth tape 3, the position of the small hole 3a is displaced due to expansion and contraction of the cloth tape 3 during the manufacturing process. Therefore, a defective product is often produced, and since it is provided in the central portion, it is necessary to use a plurality of pins 12 and 13 for stable installation. Therefore, a large number of pin holes are present in the finished product. However, there was a problem that the product value was lowered.

The present invention solves the above problems and is excellent in the strength in the pulling direction, the durability due to repeated attachment and detachment, the safety without damaging the wearer, and the excellent design. Provided is a tape-attached synthetic resin attachment / detachment method and a method for manufacturing the same.
