ABSTRACT:
A pressure sealing zipper comprising a gasket assembled to an interdigitating zipper chain which uses a slider without a diamond to penetrate between the interlocking portions of the elements. On one side of the zipper chain, a single plate slider tracks in slots adjacent the zipper tape and maintains the elements in coplanar relationship by contacting the elements both directly and indirectly through the zipper tape. The sealing gasket is carried by the elements on the side opposite the slider. This construction permits the slider to terminate above the gasket opening in a closed end sealing zipper.
