Abstract
A closure (40) and container (10) combination which includes a closing and opening assist mechanism (22, 28, 28′, 30, 30′) which provides for spreading the locking mechanism (46) of the closure and causing a lifting movement of the closure to effect the removal of the closure from the container.
Claims23
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;
- 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 first locking of said container and the second locking means of said closure are caused to flex away from one another transversely of the central axis of said container and said closure to cause relative 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.
