ABSTRACT:
A slider-operated zipper having recessed slider end stops. The recesses can be formed in top portions of the profiled closure members or in outwardly facing side portions of one or both profiled closure members. Alternatively, the openings of throughholes that pass through the profiled closure members can serve as end stop recesses. The slider has one or more projections or ridges designed to impinge on a wall of a respective recess or throughhole opening in the zipper, thereby stopping the slider, provided that the pull off resistance is not overcome.
