ABSTRACT:
A metal can lid with a push-in opening device for cans having pressurized contents in which the opening device is formed in the lid from the material of the lid and in which the opening device comprises a panel large enough to be pushed into a can to which the lid is applied by a person's finger pushing downwardly on the panel and in which the panel has a folded periphery which remains with the panel as a reinforcement for the panel against bending of the panel as it is pushed downwardly into the can. A portion of the folded periphery is separated by a line of fracture from the lid, and the lid and panel construction are made to avoid sharp exposed edges.
