ABSTRACT:
A metal beverage can having an easy opening top provided with a scored or otherwise weakened line defining a flap opening. An opening structure or member is secured to the can top at flap area and serves to aid in tearing or splitting the top along the scored or weakened line to form the flap and also serves, thereafter, to push down the flap when the can is raised to the lips of a user such that the opening member makes contact with the user's upper lip. The top of the can is concave and the opening structure is so arranged as to provide a "stop" to prevent the flap from being pushed too far into the can interior. The flap when forward and free of the curved top is constructed so that it straightens to extend the forward lip of the flap so that it serves as a "stop" to prevent, in normal service, the flap from rising above the surface of the top. The flap is resiliently biased toward that position and resiliently returns to it after it is pushed down as by the lips of a user.
