Claims33
A beverage can end comprising:
- a peripheral curl capable of being joined to a can body by seaming;
- a wall structure radially inward from the curl;
- a center panel;
- a main score defining a main hinge and a main tear panel that is capable of opening upon rupture of the score to form a pour opening;
- a tab coupled to the center panel by a rivet, the tab having a nose capable of contacting a portion of the main tear panel for rupturing the main score, a body, and a heel formed opposite the nose, the heel being configured for grasping by a user;
- a raised main bead having a first end located proximate the heel side of the tab and extending around the main tear panel to a second end;
- a vent including:
- a vent score defining a vent tear panel and a vent hinge located approximately between opposing ends of the vent score;
- and
- an upwardly protruding button located on the vent tear panel;
- and
- a recessed vent bead located about the vent score, the main bead and the vent bead being continuous such that the main bead and the vent bead join at a transition in which the raised main bead yields to the recessed bead;
- whereby actuation of the tab by lifting the heel is capable of rupturing the main score and actuation of the tab by pressing down on the tab is capable of rupturing the vent score.
