Abstract
An easy-opening end closure that may also be reclosed, suitable for joining to a container. A cover panel is bonded around its perimeter to an end panel with a rotatable lever interposed between them. To open the closure, a user applies force to the rotating lever to move it axially around an attachment point and thereby progressively debonding a substantial portion of the bond perimeter. The closure incorporates means for equilibrating pressure in the internal headspace of the container with the outside ambient for improved pouring.
