Abstract
A can end includes a main score forming in an arcuate pattern on an upper surface of the can end. The main score defines a tear panel. An anti-fracture score is disposed parallel and contiguous with the main score. The residual thickness of material after scoring ranges between 0.0045 and 0.0057 inch.
