摘要:
A vent score lacks features to arrest score propagation. Rather encourages fast score propagation upon initial rupture. Venting is achieved through a flap configuration formed by the vent score.

A seaming assembly (10) configured to seam a can end (14) onto a can body (18) to form a seamed container (20) is disclosed. The seaming assembly (10) includes a lifter assembly (27), a seaming chuck (28), and a knockout pad (30). The lifter assembly (27) is con¬ figured to lift a can body (18), and includes a spring (166). The seaming chuck (28) includes a surface (58) that is configured to contact a portion of the can end (14) during seaming. The knockout pad (30) is movable relative to the seaming chuck (28), and is configured to locate the can end prior to seaming. The spring (166) is preloaded to provide a force between 30lbf and 90lbf to the can body (18) when the lifter assembly (27) has lifted the can body (18) and the can end (14) has contacted the seaming chuck (28). The force provided to the can body (18) may increase to between 90lbf and 150lbf after the spring (166) has been compressed.
摘要:
A beverage can end (14,14a) and container (12) have a removable panel (32a) that is actuated by a tab (44a). The tab is smaller than conventional full aperture ends but enables opening because of the lower pull force required smaller ends or scores (30a) formed in less malleable allows that conventional food can ends (14,14a). A stay-on-tab is also provided.

A beverage can end has a vent that includes a button. The vent is actuated by downward force of a pull tab that is transmitted to the vent score through the button.

摘要:
A can end having a small diameter center panel and an opening of particular aspect ratio to improve the pourability and drinkability characteristics of the opening, compared to can ends having conventional openings.
摘要:
A beverage can end has a vent (40) that includes a button (50). The vent is actuated by downward force of a pull tab (70) that is transmitted to the vent score (42) through the button. The center panel (18) includes beads.
