Abstract: A substantially full opening steel can end for food product cans easily opened by an aluminum pull tab riveted to a removable panel portion defined by a score line in a recessed end wall of the can end located close to a seam between the can end and can body. The panel portion has a protective triple fold formation along its peripheral edge when removed, and the score line is located in the top layer of the triple fold formation beneath an overlying stepped tip of the pull tab which ruptures the score line during opening of the can. The score line preferably extends 300.degree., 150.degree. in each direction from the stepped pull tab tip, around the can end to retain the opened panel portion and pull tab on the can when opened.
