Abstract
A plastic, easy-opening, retortable container for hermetic sealing is provided, and a closure for such a container. The closure includes a plastic membrane having inner and outer portions defined by a groove therebetween. The groove defines a fail portion that can be torn to open the container. A grip portion is connected to the inner portion so that a user can grasp the grip portion and pull the inner portion from the container. The fail portion is strong enough to resist failure during retort but allows the user to easily remove the inner portion to thereby open the container.
