Description

Open-end zipper with finished pin box

The present invention relates to a zipper. More particularly, it relates to an open zipper with a finished pin box.

Zipper is a pair of zipper tapes with a set of teeth formed along the edge of the slider, which is inserted into both sides of the slider, so that the teeth of the pair of zipper tapes can be joined or separated according to the reciprocating motion of the slider. It is a fastener. Such a zipper may be referred to as a zip, a chirk, a fastener, a slide fastener, and the like, and is used for various purposes in various clothes and fashion accessories.

Specifically, zippers may be classified into a closed-end zipper, an open-end zipper, and a two-way separator zipper, depending on their function. Among them, the locked zipper is a zipper having a shape in which one or both ends of the two zipper tapes are joined in a state where a pair of zipper tapes are completely opened by a slider. The open zipper is a zipper having a shape in which a pair of tapes are separated from each other in a state in which a pair of zipper tapes are completely opened by a slider. The two-way zipper is a zipper with two sliders that can open and close a pair of zipper tapes in both directions. Such a two-way zipper is also classified into a two-way zipper in which two sliders are arranged in head to head, and a two-way zipper in which two sliders are arranged in bottom to bottom.
