Abstract
A can closure includes a plastic insert permanently installed in a hole in the can top, and a plug which seats in a pouring aperture extending through the insert. Locking dogs on both the insert and the plug provide a bayonet-type connection so that the container can be resealed after its contents have been partially used. Protrusions on the locking dogs prevent the plug from being fully removed until pressure within the container has been relieved.
