ABSTRACT:
A slider-zipper assembly for reclosable packaging in which separation of the zipper halves occurs in the vertical plane. The package comprises front and rear walls disposed on opposing sides of a vertical plane; first and second zipper parts respectively joined to the first and second walls; and a slider for displacing the first zipper part relative to the second zipper part in a downward direction parallel to the vertical plane. In one embodiment, the slider comprises a top wall, first and second side walls connected to the top wall, and an inclined projection projecting from an inner surface of the second side wall. The projection engages a groove in the vertically displaceable zipper part. The end of the projection nearest to the closing end of the slider is located closer to the top wall than is the other end of the projection. In another embodiment, a projection can be formed on the zipper part that engages an inclined groove formed in the slider.
