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.
