Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to underwear, outerwear,
The present invention relates to a tape-attached snap which is attached to an opening / closing portion of a jacket or the like, a bag, a bag, a footwear or the like to perform an opening / closing function or a stopping function.

[0002]

2. Description of the Related Art In general, it is selectively used for a tying portion of underwear, outerwear, outerwear, and the like, an opening / closing portion of bags, bags, footwear, and the like, or a binding connection portion of a binding band. Buttons, snap buttons, tape snaps, fasteners, and tapes of the surface mounting tape are the male tapes formed by fixing a plurality of synthetic resin male snaps to the cloth tape at predetermined intervals by resin molding means. A female tape formed by molding a plurality of female snaps made of synthetic resin on a cloth tape at the same interval as the male snaps. A long cloth tape having a mounting hole with a diameter smaller than the outer diameter of the base is provided. A snap forming space of the die and a mounting hole are provided between the upper and lower dies having the space for snap forming and the tape retaining pin. After being clamped and sandwiched, the molten resin is injected into the molding space, and the front side and the back side of the snap base formed on both sides of the cloth tape are continuously integrated through the mounting hole, and integrated. The periphery of the mounting hole is sandwiched between the front surface side and the back surface side of the snap base.

[0003]

The snap with a tape having the above structure is obtained by sewing a cloth tape cut to a predetermined length according to an object to be used and a position without fixing each snap itself to the object. It is used, but since the front side and the back side constituting each snap base are integrated through the mounting holes formed in the cloth tape, the bonding strength between the front and back sides is strong, and However, there is an advantage that the detachment durability of the female snap is secured.

[0004] However, the fabric tape is sewn and fixed to the object without each snap being fixed to the object, and the integrated strength of sandwiching the fabric tape between the front surface side and the rear surface side constituting each snap base is high. When the fabric tape is subjected to a large or repeated tension due to its weakness, the force is concentrated on the narrow widthwise edge formed by the drilling of the mounting hole, and the fabric tape is broken. In addition to the fatal drawback that each snap comes off the cloth tape and the opening / closing function or the stop function is lost, it is necessary to previously drill a mounting hole in the cloth tape, The snapping space of the mold and the mounting hole are formed by the expansion and contraction of the tape itself in which the tape has been pierced due to the dry and wet condition, or the extension due to the application of a tension force for preventing the tape from being loosened when the tape is disposed between the upper and lower dies. Pick Mismatch occurs, like many defective products are generated, a problem to be solved in the fabrication cost and quality assurance.

According to the present invention, a male snap and a female snap are firmly formed and fixed without drilling a mounting hole in a cloth tape, so that an opening / closing function or a stopping function can be ensured, manufacturing costs can be reduced, and quality can be ensured. It is an object to provide a snap with tape that can be achieved.

[0006]

According to the present invention, there is provided a male tape (3) in which a plurality of male snaps (1) made of synthetic resin are formed and fixed on a cloth tape (2) at predetermined intervals by resin molding means.
And a female tape (6) formed by fixing a plurality of synthetic resin female snaps (4) to a cloth tape (5) at the same interval as the male snaps (1). For the fabric tapes (2) and (5), use a non-melted fabric such as cotton or blended fabric and a braided or woven tape having a roughness that allows the molten resin to pass therethrough. And a plurality of female snaps (4) on the other fabric tape (5) at predetermined intervals without drilling fixing holes at their forming and fixing positions. The gist is a configuration of a snap with a tape, which is characterized by being fixed. Note that the roughness that penetrates through means that the molten resin will be described later.For example, the molten resin injected into the molding space forming the male surface side portion (13) passes through the cloth tape (2), and the male back side portion (12 ) Means the roughness that enters the molding space.

A dough tape (2) woven to a roughness that allows the molten resin to penetrate and penetrate by the molding pressure is closely interposed on the entire surface, and the molded members on the male back side (12) and the male front side (13) are mutually interposed. The male tape (1) is formed by being integrated with the fabric tape (2) in a fused state by passing through the fabric tape (2) .The configuration of the female tape (6) is the same as that of the male tape (3). By injection molding means using resin, the female back side (42) with a recessed engagement hole (41)
A dough tape (5) woven to a roughness that allows the molten resin to permeate and penetrate by the molding pressure is closely interposed over the entire surface between the female back side (43) and the female back side (43), The female snap (4) is formed by allowing the molded members of the part (42) and the female surface side part (43) to pass through the fabric tape (5) and to be integrated in a fused state.

The engaging leg (11) of the male snap (1) is
A bulging edge for engagement (15) and a concave portion (14) for expansion and contraction due to resin elasticity are formed around the distal end, and an engagement hole (41) of the female snap (4) is formed with a mold inside the opening. Although the configuration is shown in an undercut state in which the engagement edge (44) is formed in a range that allows removal, it is not limited to this,
It is sufficient if the configuration of the engagement relationship is normally implemented, and it is not limited to the polyacetal resin, and it is needless to say that other thermoplastic resins used for forming a normal snap can also be used. .

Further, the bottom surface of the concave portion (14) formed on the male snap (1) for expansion and contraction is shown as a flat bottom by a cloth tape (2) integrated by resin penetration. As shown in FIG. 5, when the peripheral end of the core pin (C) in the middle dent protrudes from the parting line (P), the bottom of the recess (14) closes the core pin (C). Tension is applied to the dough tape (2) by the peripheral edge of ()), the apparent weave structure becomes coarse and the penetration of the molten resin is improved, and the male snap (1) at the male surface side during injection molding (13) Since the molten resin injected from the gate (G) at the center of the wadding passes through and penetrates the fabric tape (2) into the middle recess, it forms a bulge at the center. In some cases, the integrated area with the male snap (1) is increased to increase its strength. In the drawing, (p) is a pin hole formed by a cloth pressing pin formed on the mold, and formed at equal intervals on the same radius line, and a cloth tape is formed.
In addition to the stable holding of (2), this is in consideration of the mitigation of the heat shrinkage deformation of the thick part and the economical efficiency of the amount of resin used. snap
(1) The female snap (4) may also be formed.

In the embodiment, the woven fabric tape is used. However, the woven fabric tape may be a woven fabric tape, and is not limited to cotton fabric. The object of the present invention can be achieved by using a cloth that transmits the.

The snap with tape constructed as described above has a non-woven fabric woven to a roughness that allows molten resin to permeate and penetrate by molding pressure between upper and lower molds having snap molding spaces arranged in several rows. After arranging the fabric tape (5) with holes, closing the mold, injecting the polyacetal molten resin into the molding space, molding the front surface side and the back surface side of each snap base formed on both sides of the fabric tape. It is manufactured by integrating with a polyacetal molten resin that penetrates the cloth tape by pressure.

[0011]

According to the snap with tape of the present invention described above, a plurality of male snaps (1) made of synthetic resin are fixed to the cloth tape (2) at predetermined intervals by the resin molding means. Tape (3) and synthetic resin female snap
And a female tape (6) formed by fixing a plurality of (4) to the male tape (5) at the same interval as the male snap (1).
For (5), use a non-melting fabric such as cotton or blended fabric, and use a braided or woven tape to the roughness that the molten resin passes through, and use a male snap (1) for one fabric tape (2). A plurality of female snaps (4) on the other cloth tape (5), and a plurality of female snaps (4) are formed and fixed at predetermined intervals without drilling fixing holes at their forming and fixing positions. In the manufacturing process, it is no longer necessary to previously drill mounting holes in the fabric tapes (2) and (5), and the forming of the molding die caused by the presence of the mounting holes and expansion and contraction of the fabric tape. This eliminates the need for a troublesome operation of matching the positions of the working space and the mounting holes, and eliminates the occurrence of defective products due to the mismatch, thereby making it possible to provide the device at low cost.

In particular, as the fabric tapes (2) and (5), non-fusible fabrics such as cotton and blended fabrics, which are braided or woven to a roughness that allows the molten resin to penetrate, are used in a non-porous state. In this way, the strength of the fabric tapes (2) and (5) can be secured, and the integrated strength of the male snap (1) and female snap (4) for the fabric tapes (2) and (5) increases. The snaps can be made thinner to reduce the discomfort caused by the thickness when used for clothes, and the snaps may be detached from the fabric tape due to breakage when using a fabric tape made of resin fiber yarn. Thus, a snap with a tape having excellent durability, which can maintain the opening / closing function or the stopping function for a long time, can be provided.

Further, as the fabric tapes (2) and (5), cotton,
