Abstract
The plastic cover is easily removed from a metal container to allow the plastic cover and the metal container to be separately recycled. The lip that holds the plastic cover to the metal container has two or more circumferential ends which have a lower degree of engagement than the remaining portion of the lip. A press point on the cover which transforms the circular cover into an elliptical shape is positioned on the outside of the cover opposite the circumferential ends and a shoulder is mounted inside the cover opposite the press point. The shoulder bears against the container to assist in removal of the cover. Where the cover has both an inner cylinder and an outer cylinder, a rib is employed to connect the inner cylinder of the cover to the outer cylinder of the cover and to transfer pressure from the press point to the inner cylinder.
