ABSTRACT:
A container end, including a die and the method for making, for pressurized containers includes a circular center panel, an inner annular panel around the center panel, and an outer annular panel around the inner annular panel. The inner annular panel has a generally arcuate cross-section viewed in a plane extending radially from the centerpoint of the container lid. The inner annular panel comprises a plurality of first segments, spaced apart about the circumference of the inner annular panel, and a plurality of second segments, with at least one second segment being positioned between adjacent pairs of first segments. The radius of curvature of the arcuate cross section of each of the first segments is less than the radius of curvature of the arcuate cross section of each of the second segments, so that the radius of curvature of the inner annular panel varies along the circumferential length of the inner annular panel.
