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.

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 thereby engaging integrated mechanisms to progressively debond segments of the perimeter seal.

To open the closure, a user applies force to the rotating lever to move it axially around an attachment point and progressively debond the seal perimeter. In this process, latching mechanisms ensure uni-directional movement of the lever relative to the shutter and joining of the two components at the end of the rotational sweep.

An improved easy opening closure wherein a cover panel is bonded to a container end panel around the perimeter of an aperture through the end panel. A rotating lever is connected to a proximal lever through a rivet acting as a fulcrum such that, as pressure is applied to rotate the rotating lever axially around the rivet, the force is magnified which allows the proximal lever selectively debonds an isolated region of the perimeter, thereby allowing pressure within the container to escape. Continued rotation of the rotating lever further debonds the cover panel from the end panel. The leading edge of the rotating lever wedges between the end panel and the cover panel at the opposite edge of the aperture, thereby cleaving and debonding the connection between the panels at that edge.
