Abstract: A molded plastic container assembly comprising an open top container and a closure which sealingly fits on the top of the container. A collar is integral with the container sidewall just below the top rim to provide a space into which the lower edge of the closure skirt extends to prevent removal closure until a tear strip formed in the collar is removed. The tear strip in the collar extends fully through one corner of the container assembly and at least half way toward both of the adjacent corners to provide substantial area of access to the closure lower edge as well make the tear strip to large to present a choking hazard to small children.
