Child Resistant Locking Zipper

Abstract

This invention prevents the unwanted opening of a zipper. The invention comprises one or more grippers affixed to the zipper tape which engage the zipper pull tab and prevent movement of the zipper slider. The design and construction minimize shortcomings in other locks.
