ABSTRACT:
A slider-zipper assembly for reclosable packaging in which the slider is coupled to the top portions of the zipper parts. The zipper can be either a flanged zipper or a string (i.e., webless) zipper. In one embodiment, the slider has a pair of diverging profiled projections that fit in and interlock with respective profiled grooves in the zipper parts. In another embodiment, the slider has a pair of diverging profiled grooves that receive and interlock with respective profiled projections that project upwardly from the zipper parts. Alternatively, the slider could have one projection and one groove for interlocking with the respective zipper parts. The diverging profiles on the slider cause adjacent sections of the zipper to open as the slider is moved in the zipper opening direction. Alternatively, the projections on the slider could be discontinuous.
