An ecology stay-on tab beverage can end has a first axis extending though a rivet. A tear panel is defined by a frangible score and a non-frangible hinge that joins a first end of the frangible score with a second end of the frangible score. The first axis forms a line of asymmetry of the tear panel. A second axis intersects the first axis at a right angle. An intersection of the first axis with the second axis defines a center point of a clock-like reference having a 12 o'clock position at the first point and a 6 o'clock position at the second point. A first radius of curvature of the frangible score between a 5 o'clock position and a 7 o'clock position is at least 3.6 times larger than a second radius of curvature between a 7 o'clock position and a 9 o'clock position.

Beverage can end frangible score geometry

An ecology stay-on tab beverage can end has a center panel having a public side and an opposing product side. The center panel has a displaceable tear panel defined by a frangible score groove and a non-frangible hinge portion of the center panel located between a first end and a second end of the frangible score which retains the displaceable tear panel to the center panel subsequent to opening. The displaceable tear panel has a symbol thereon. The symbol conveys information to a user and is formed by a relief feature on the tear panel. The symbol and the relief feature are spaced at least 0.050 inches radially inwardly of the frangible score groove such that no portion of the symbol and the relief feature are closer than 0.050 inches to the frangible score.
