ABSTRACT:
An improved vapor-seal, child-resistant closure and container combination is disclosed herein. The container comprises a cylindrical plastic body which is molded in one piece and has circumferentially spaced, radially extending projections on the upper end thereof that have notches therein. The closure comprises a one-piece plastic body having a top panel and an annular depending skirt with circumferentially spaced lugs extending radially inwardly for engagement with the notches. An annular integral rim or abutment is provided on the annular surface of the top panel of the closure and depends downwardly therefrom. A unique two-piece, vapor-seal liner is interposed between the annular abutment and the lugs for engagement with the upper end of the container. The two-piece liner incorporates a resilient disk member which serves as a spring between the closure and container and a deformable disk positioned beneath the resilient disk which may be pressed into sealing engagement with the upper rim of the container to provide a vapor-tight seal between the closure and container.
