VAPOR-SEAL SAFETY CAP AND CONTAINER G.V. Mumford ABSTRACT OF THE DISCLOSURE 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, one-piece, vapor-seal liner is interposed between the annular abutment and the lugs for engagement with the upper end of the container. The one- piece liner comprises a disc member which engages the annular rim of the container and includes a downwardly depending plug member which provides a vapor-tight seal with the in- side surface of the container. The liner also serves as a spring between the closure and the container to bias the closure lugs into engagement with the projections on the container.
