CONTAINER, ENGAGEMENT RING AND COVER ASSEMBLY Abstract of the Disclosure: An upwardly open end portion of a plastic container straight sidewall is telescoped by an inverted U-shaped portion of a plastic engagement ring with a generally transverse, outward flange on the container sidewall snap interengaging with a similar engagement ring flange. An engagement ring U-shaped portion extends transversely inwardly having, in certain embodiments, either a simple or complex outer wall common with the inverted U-shaped portion and in all cases an interior wall spaced inwardly therefrom. An edge portion of a plastic cover overlies the engagement ring U-shaped portion and has a downward extension fitting therein divided into an exterior wall outwardly abutting the ring U-shaped portion outer or common wall and a transverse inward flange snap interengaging with a similar flange on the ring interior wall. The cover edge portion terminates inwardly at an interior wall which outwardly abuts the ring U-shaped portion interior wall and a cover transverse connecting part joins the edge portion interior wall vertically intermediate both the cover edge portion interior wall and the ring U-shaped portion interior wall. In the assembly, the engagement ring and cover are constructed to exert transverse pres- sure outwardly to outwardly abuttingly pressure seal between the cover edge portion and the engagement ring, and between the engagement ring and the container side- wall inner side. The cover edge portion terminates outwardly in a transverse flange spaced above the engagement ring and engageable by a tool for removing the cover from the engagement ring.
