Reclosable self-opening can end

Easy opening container wall for a pressurized container, comprising:

• a contained wall which is normally flexible and which is maintained relatively inflexible by pressure within the container;
• a panel defined in said wall at least in part by a selectably separable region;
• means defining a normally closed and selectably rupturable pressure release opening in said wall;
• opening tab means disposed on said wall for movement along a path;
• first means on said opening tab means operable to rupture said pressure release opening in response to force having a substantial component normal to said wall directed to said opening tab means, with said opening tab at a predetermined location on said path;
• second means on said opening tab means operative to apply force to said panel at a point which traverses said panel as said opening tab means is moved away from said predetermined location on said path, thereby progressively separating said separable region and displacing said panel away from wall into the container so as to expose an opening into the container.
