Abstract
An improved convenience closure that is adapted for sealing an end of a can includes an end panel having a peripheral score, a rivet formation, a mustache score and a flex line score defined therein. The mustache score may include a central portion that is positioned radially inwardly on the end panel relative to the rivet formation. The central portion is preferably curved, with a concave side of the curvature facing the rivet formation. The mustache score also may include first and second preferably symmetrical end portions, each of which is continuous with the central portion. Most of the total length of each of the end portions may be curved away from a nearest portion of the peripheral score, with a convex side of curvature facing the nearest portion of the peripheral score. Tooling for making the convenience closure and a method of making such a convenience disclosure are also disclosed.
