A can end for a container has a curl defining an outer perimeter of the can end. A chuckwall extends downwardly from the curl. A means for increasing the strength of the can end is integral with the chuckwall, and a center panel is integral with the means for increasing the strength of the can end. The center panel is centered about a longitudinal axis, and has a product side, a public side, a rivet, and a displaceable tear panel at least substantially defined by a frangible score and a non-frangible hinge segment. A non-detachable tab is staked to the central panel wall by the rivet. The non-detachable tab has a nose end extending over a portion of the tear panel, a lift end opposite the nose end, and a central webbing between the nose end and the lift end. The central webbing has a hinge region and a rivet island surrounding the rivet. The rivet island is at least partially surrounded by a first void region to provide a first exposed area of the central panel. The central webbing further comprises a second void region between the lift end and the first void region to provide a second exposed area of the central panel. The first and second void regions are separated by a narrow strip of the central webbing. A portion of the narrow strip extends downwardly and approaches the public side of the central panel wherein a height of the lift end of the tab above the public side of the central panel is maintained at a predetermined height. ® KIPO & WIPO 2007
