Cap structure for zipper

Abstract

A cap structure for a zipper includes a cap and a resilient tab. The cap has a containing groove formed on the bottom surface thereof. At least one lug is disposed on the bottom surface of the containing groove. The bottom of the concave portion is lower than the top of the lug. Two sides of the cap each have a side wall. Each of the side walls has a recess opening that communicates with the containing groove. The resilient tap is disposed within the containing groove and the resilient tap abuts against the limiting portions. One end of the resilient tap has an aperture that corresponds to the lug. Therefore, the resilient tap and cap are combined to form the cap structure. Because the space for the resilient tap to bend is bigger, the force for pulling the slide of the zipper is smaller.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a cap structure for a zipper and in particular to a cap structure assembled on the slide of the zipper and having a resilient tap installed within the cap structure.[0003]2. Description of Related Art[0004]In general, a slide of a zipper is locked on interlocking teeth of a zipper tape (not shown in the figure). The slide of the zipper structure includes a zipper slide, a pull tab, a hook, a resilient tap, and a cap. The top of the slide of the zipper has two holding bases. A hole of the pull tab is looped around one of the holding bases of the zipper slide. The hook is disposed movably inside of the zipper slide. The resilient tap is disposed on the slide of the zipper and attached to the top of the hook. Furthermore, the cap is covered on the pull tab to lock the resilient tap inside the cap. The top of the pull to passes through a concave portion of the cap.[0005]When a user wants to ...

AI Technical Summary

Benefits of technology

"The present invention provides a cap structure for a zipper, which includes a cap, a resilient tap, and a lug. The cap has a containing groove with a concave portion and a limiting portion. The resilient tap is disposed inside the containing groove and abuts against the limiting portions. The resilient tap has an aperture corresponding to the lug. The cap structure makes it easier to assemble the zipper slide, and requires less force to move it."

Problems solved by technology

However, when a manufacturer has to assemble the resilient tap with the zipper slide, and then cover the cap on the slide of the zipper to assemble the zipper slide.

The assembly of the slide of the zipper is complex and inconvenient.

Moreover, a user must use a large force to pull the pull tab to bend the resilient tab.

The pulling of the pull tab is difficult.
