Abstract
A can end for a beverage container has a center panel with a stay-on tab opening system. A tear panel is defined by a first frangible score and a non-frangible hinge segment. A tab is attached to the center panel by a rivet. The tab has a void region partially surrounding a rivet island. A first circle has a first center point located at a center of the rivet and a first radius equal to a distance from the center of the rivet to a radially outermost point of the void region on a first axis running through the nose and lift ends of the tab and a center of the rivet. A second circle has a coincident center and a second radius less than 2.5 times first radius. A second frangible score is spaced completely radially outwardly from the rivet island and between the first and second circles.
