ABSTRACT:
A method of reforming a countersink (14) of a container end (10) from a shell (10') is disclosed. A shell (10') is provided having a center panel (12') including an initial panel height (A') and an initial panel diameter (D'). The shell further has an integral countersink (14') including an initial countersink depth (A'), an inner wall (30') and an outer wall (32') being joined by a curved countersink bottom (34'). The bottom has an initial bottom radius (R1). The panel (12') is joined to the inner wall (30') of the countersink by a curved shoulder (36') having an initial shoulder radius (R2'). The shell is reformed by decreasing the panel height, increasing the panel diameter and decreasing the countersink depth. The reformed shell (14") is further reform by increasing the panel height and further decreasing the countersink depth.
