ABSTRACT:
There is disclosed a novel cover and container assembly having a container portion and a cover portion wherein there is formed a bellows-like portion of at least two annular grooves separated by a ridge on the cover or container portion for dampening external pressure forces after impact and further having an interlocking assembly providing a contact area between the cover and the container. The interlocking assembly provides a snap-type closing which ensures a tighter fit with less chance of opening with one annular groove including rib members located near the edge of the cover, with the rib members providing means for separating the cover from the container.
