An improved full-open type of convenience closure includes an end panel having a peripheral score defined therein to define fixed and removable end panel portions, a tab having a nose portion for exerting a downward force on the end panel adjacent the peripheral score, a rivet formation for securing the tab to the end panel, and a moustache score for, among other purposes, providing a pivot point for the tab. The rivet formation includes a raised area on the end panel which is defined by an outer edge. The moustache score is curved away from the peripheral score at the point where it intersects the outer edge, thereby preventing tearing along the outer edge during opening.
