Abstract
An ecology end member for a beverage container has a central panel wall with a product side, a public side, and an outer peripheral edge. A non-detachable tab is secured to the public side of the central panel wall by a rivet. A displaceable tear panel is located in the central panel wall adjacent the rivet. The tear panel is defined by a frangible score and a non-frangible hinge segment. The frangible score has a tear panel geometry with an outer periphery defied by a curvilinear score length. The tear panel geometry is asymmetrically skewed having a large radius of score curvature in a first outer quadrant of the tear panel to provide low resistance to opening the tear panel at the large radius. The tear panel has a radially outermost segment of the score located in a different quadrant of the tear panel.
