Abstract:
1. A container and closure combination comprising: a container including a bottom wall, an associated side wall defining a hollow interior, a finish having an outer surface and an inner surface, the finish providing communication with the hollow interior and having a central axis, and a first locking means on the outer surface of the finish; a spreading cam and a lifting cam disposed on the outer surface of the finish, wherein at least one of the spreading cam and the lifting cam is adjacent the first locking means; and a closure to cover the finish of said container including a second locking means cooperating with the first locking means of said container, said closure having a central axis, whereby upon relative rotational movement of said closure and said container, the spreading cam causes the first locking means of said container and the second locking means of said closure to flex away from one another transversely of the central axis of said container and said closure and the lifting cam causes relative axial motion of said container and said closure generally parallel to the central axis of said container and said closure to effectively separate said closure from the finish of said container.
