Abstract: A resealable closure for beverage containers uses initial physical interference to initiate a seal between a sealing flap and a dispensing port in a lid of the resealable closure. Once the initial seal is achieved, a pressure differential develops, resulting in additional force tending to bias the sealing flap toward the dispensing port. The sealing flap is actuated by an external drive means, that can also be a dust cover to prevent debris from contaminating any surfaces that may come into contact with the contents of the beverage container. There is a slack between initial movement of the external drive means and initial movement of the sealing flap, during which the pressure differential is preferably equalized through the unsealing of a vent hole in the resealable closure.

Abstract: The invention is relating to a process of rolling the brim of a can of a metal-plastic-metal construction on a small diameter without provoking a crack in the metal layer (3) in the course of this folding operation. This process consists of reducing locally the thickness of plastic (2) in the zone (5) or (6) being rolled in order that the construction reduced to a thin layer of plastic (2) between two foils (3) and (4) of metal behaves nearly as a foil of homogeneous metal. The plastic flowed toward outside of the zone intended to be rolled forms a bulge either towards the exterior of this zone (7) or towards the interior (18). The process applies to food cans and to beverage cans of a metal-plastic-metal construction, as well as to the ends of these cans. The can bodies and ends fabricated by the process constitute equally an object of the invention.
