A can end member has a central panel, a circumferential chuckwall, and a transition wall. The central panel is centered about a longitudinal axis and has a peripheral edge. The curl defines an outer perimeter of the end member. The circumferential chuckwall extends downwardly from the curl to the transition wall. The transition wall connects the chuckwall with the peripheral edge of the central panel. The transition wall has a folded portion extending outwardly relative to the longitudinal axis.
