ABSTRACT:
A container end closure includes an end wall having a removable panel defined therein by a rupturable peripheral score, and a pull tab having a nose portion at one end, a handle portion at its opposite end, and marginal edge portions which extend generally toward the end wall and terminate short of the outer end of its nose portion. At least one depressed section is formed in the removable panel of the end wall to accommodate the terminal ends of the marginal portions of the tab, upon pivoting of the tab when the handle portion is raised. This construction ensures that initial contact with the panel is made by the outer end of the nose portion of the tab, thereby maximizing the effectiveness of force applied for score rupture initiation.
