[0049] According to the first embodiment of the reverse opening detachable end stop of the zipper shown in FIGS. Mobile body. The tooth chain 5 is manufactured by winding a synthetic resin monofilament such as polyamide, polyester, etc. into a roll or bending it into a zigzag shape to form linear fastener elements 7 continuous in the longitudinal direction of the fastener tape 8, and then wrapping the core The thread 12 passes through the inside of the fastener element 7, and utilizes the sewing thread 9 to sew it along the longitudinal edge of the fastener tape 8 along one side. Alternatively, by injection molding, thermoplastic resins such as polyacetal, polyamide, polypropylene, and polybutylene terephthalate may be used at predetermined intervals along the longitudinal direction of the fastener tape 8 . A single group of fastener teeth is formed on the expansion part formed by one side edge of the longitudinal direction of 8, so as to form tooth chain 5.

[0069] According to the second embodiment shown in Figures 13 and 14, the reverse-opening detachable end stop of the zipper is characterized in that the seat tube 3 has a function for limiting the reverse-opening slider 1 to the inner side of the tooth chain 5 Mobile body. The structure of the tooth chain 5 is the same as that in the first embodiment. In the fastener chain 5, utilize the sewing thread 9 to sew the coiled fastener element 7 containing the core thread 12 along the longitudinal side edges of the fastener tapes 8, 8 of a pair of left and right single side fastener chains 6, 6. The reinforcing part 10 is formed by bonding a resin film to a vacant part 11 disposed at one end of each one-sided fastener chain 6, 6 in the longitudinal direction, and the seat tube 3 is made of a thermoplastic resin film on the reinforcing part 10 of the one-sided fastener chain 6. Formed, and the insertion tube 4 is formed by thermoplastic resin on the reinforcement part 10 of the othe...

Abstract

The present invention provides a reverse opening type separable end stop having a mechanism which securely locks a reverse opening type slider (1) on a surface of an insert pin (4) or a box pin (3), thereby blocking the slider (1) from needlessly moving inward. The reverse opening type separable end stop is constituted of a reverse opening type slider (1), a box pin (3) and an insert pin (4). The insert pin (4) or the box pin (3) is provided with a contact portion (13) with which a locking pawl (35) provided on the reverse opening type slider (1) mounted on a fastener chain (5) can always make contact by colliding an end surface thereof in an opening / closing direction at an end portion of the fastener chain (5), so that the contact portion (13) is locked by the locking pawl (35). Consequently, the reverse opening type slider (1) is prevented from automatically moving inward of the fastener chain (5) needlessly, whereby a high quality reverse opening type separable end stop is ensured.

Description

technical field [0001] The present invention relates to a reverse-opening detachable end stop of a zipper, and in particular to a reverse-opening detachable end stop. The end stop is detachable by improving the reverse-opening The seat tube and the insertion tube of the end stop can smoothly carry out the separation operation of the end stop, and the end stop includes a reverse opening slider, a seat tube and an insertion tube. Background technique [0002] The zipper is used not only as an opening / closing device of an opening portion of clothes or bags but also as a connecting device of blankets or artificial turf divided into unit sizes. While this type of slide fastener that can be opened or closed from one end side to the other end side in the longitudinal direction of the fastener chain is general, there is another slide fastener that can be opened or closed from both end sides in the longitudinal direction of the fastener chain. In this type of zipper, two sliders (i....
