ABSTRACT:
A can lid includes a push-down gate formed in a panel portion below a narrow underfolded rim in the opening in the lid. The outline of the gate at this underfold is a score cut through the panel to permit the gate to swing downwardly and into the can. This structure is essentially the same as in the Klein, Harper Pat. No. 3,334,775; however, the panel portion in the can lid includes a sealant formed of a settable liquid which, through capillary action, extends into the underfolded rim, and through the score cut to plug the opening thereof until the lid is depressed.
