ABSTRACT:
Flexible zippers having sculpted slider end stops and reclosable packages incorporating such slider-operated zippers. In one embodiment, the flexible zipper comprises a joined end and a slider end stop that projects laterally beyond a side surface of the major portion of the zipper. The slider end stop is integrally formed with an adjoining portion of the joined end. In another embodiment, the flexible zipper comprises a joined end and a slider end stop that projects upward to an elevation higher than an elevation of a top surface of the major portion of the zipper and is laterally offset relative to a vertical midplane of the zipper. This slider end stop is also integrally formed with an adjoining portion of the joined end. These structures can be combined to form an end stop that projects upward and laterally outward. Each end stop is asymmetric relative to a vertical midplane of the zipper.
