An end closure (10) for a container providing a tab (26) with increased resistance to rotation upon a rivet (28) is disclosed. The end closure (10) has a central panel wall (12) having a product side (12b), a public side (12a), a rivet (28), and a displaceable tear panel (20) in the central panel wall (12) at least substantially defined by a frangible score (22) and a non-frangible hinge segment (24). A tab (26) is attached to the public side (12a) of the central panel wall (12) by the rivet (28). At least a nose portion (30) of the tab (26) of the tab (26) extends over a portion of the tear panel (20). A lift end (32) of the tab (26) is opposite the tab nose (30). The tab (26) has a central webbing (42) between the nose (30) and the lift end (32). The central webbing (42) has an anti-rotation member (52) in communication with the public side (12a) of the central panel wall (12). The anti-rotation member (52) provides a spring force against the central panel wall (12). |
