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.

A metal beverage can having a top metal wall with means defining a weakened line thereon, which line is shaped in the outline of a flap, and which line substantially surrounds and defines a flap area of the top metal wall and extends to be adjacent one edge of the can top and which, when the weakened line is ruptured, forms a flap which can pivotally move downward into the interior of the can so as to provide a pour opening; an opening structure mounted atop said top and serving to allow rupturing forces to be applied to said weakened line, said structure being mounted to said top so as to extend over said flap area; said flap when formed after said line is ruptured being resiliently pivoted so as to, when pivotally depressed within said can below said top, return under spring bias to said area; and said structure mounted atop said flap being so configured as to present a smooth surface above the flap which surface is sized and shaped to contact with the lip of a user of the can who brings the can top to his or her lips with the flap opening near the mouth and in response to such contact to resiliently pivot the flap after it is depressed, downward into the can so as to open the pour opening and allow the user to drink from the can.
