Abstract
A slider-zipper assembly for reclosable packaging in which the slider is mounted inside the zipper. Each zipper part comprises a base and a closure element connected to the base, the respective closure elements being mutually engageable. The slider comprises a body having one end where the zipper is open and another end where the zipper is closed, a first direction being directed from the closed end to the open end and a second direction being opposite to the first direction. A pair of camming surfaces on the slider have respective fixed positional relationships to the body and are divergent in the first direction. These camming surfaces are disposed so that the zipper parts are respectively cammed toward each other as the slider is moved in the first direction and cammed away from each other as the slider is moved in the second direction. No part of the slider confronts the exterior surfaces of the bases of the zipper parts.
