A resealable opening for a can where the seal is pushed away from the can top inner surface to open

摘要

Disclosed is a resealable can end combination that allows the contents to remain carbonated or pressurised. The combination comprises a metal can end and a resealable closure coupled to the can end, the can end comprising a peripheral wall and a centre panel, the centre panel including an upper surface, an opposing lower surface, and an aperture formed through the centre panel. The resealable closure comprises a base plate and a top plate coupled to the base plate at a first location, the closure has a sealed position in which at least one of the base plate and top plate contact the centre panel about the aperture to form a seal, an intermediate position in which the closure is proximate the aperture but not sealed, and a fully open position in which the aperture is exposed to enable pouring liquid through the aperture. The resealable closure also has a plug arrangement adapted to seal one or more vent pathways when the closure is in the sealed position, and a biasing means of a plastic spring adapted to bias the plug arrangement towards its sealed position. The base plate is downwardly moveable relative to the top plate when moved from the sealed position to the intermediate position. The base plate and top plate being translatable together relative to the can end from the intermediate position to the fully open position and translatable together relative to the can end back from the fully open position to the intermediate position. The base plate is upwardly moveable into engagement with the centre panel from the intermediate position into a resealed position forming at least one of a bore seal and a flange seal. The base plate further includes a wing, adapted to ride on a cam surface to allow relative movement between the base plate and the top plate to enable venting.
