<p>A safe container end closure (20) includes an annular central lid portion (36), an annular peripheral lid portion (34), and a score line (32) having a v-shaped groove with a rounded nose portion therebetween. An opening tab (26) is secured to the central lid portion having a nose (54) positioned adjacent the score line (32) so that upon pivoting of the opening tab, the nose (54) causes a portion of the score line to sever. The central lid portion (36) includes an outwardly opening intermediate fold (44) and an inwardly opening bottom fold (48) that extends radially outwardly beyond the score line (32) so that the severed edge of the removed central lid portion is rendered safe. A nose spread (31) below the scoreline defines the extent that the severed edge of the central lid portion can move. The nose spread in the area of the nose of the opening tab is greater than at other areas.</p> |
