Patent ID: 7673768

Claim:
A lid for a can body comprising: a center panel having a central axis that is perpendicular to the center panel; a countersink that extends radially from the periphery of the center panel; a first nonlinear member that extends radially from the periphery of the countersink, the first nonlinear member having first and second ends and a radius of curvature of less than about 0.5 inches, the center point of the radius of curvature of the first nonlinear member being below the surface of the lid, and wherein a line passing through the first and second ends is at a first angle from about 20 to about 80 degrees with respect to the central axis; a step portion extending radially outward from the second end of the first nonlinear member, the step portion having a radius of curvature of from about 0.02 to about 0.06 inches, and the center point of the radius of curvature of the step portion being above the surface of the lid; a frustoconical member that extends radially from the step portion and that is inclined at a second angle with respect to the central axis from about 4 to about 12 degrees; a second nonlinear member that extends from the periphery of the frustoconical member, the second nonlinear member having a radius of curvature of from about 0.04 to about 0.09 inches with a center point below the surface of the lid; and a peripheral curl that extends from the periphery of the second nonlinear member.
