Abstract
An aluminum food product container or can having an easily opened can end seamed to one end of the can body. The outer surface of the can end member has a score line along which the can end is severed for opening the can and removing an end panel. The score line is located adjacent and above a shoulder in the can body extending inwardly below the seam. A protective double fold is formed in the can end by extending the end metal annularly inwardly in a first layer from the score line, then reversely outwardly in a second layer beneath the first layer to a location circumferentially underlapping the score line location, and then reversely inwardly in a third layer beneath the first two layers into the can end panel portion. The double fold formation presents a dull hazard-free edge to the end panel when torn from the can end member.
