ABSTRACT:
A leakproof plastic zipper with integrated end stops for a zipper slider particularly suited for thermoplastic bags. An increased flange height above the interlocking elements of the zipper and an increased plow depth on the separator of the slider extending down between the flanges provide a means of stopping the travel of the slider past the ends of the zipper. The separator structure depending from the slider has a configuration in vertical cross-section corresponding to an inverted T, the horizontal portion of the T having the ends thereof adapted to be received in window structure in the flanges above the interlocking elements and adjacent one of the integrated end stops.
