Can top with an overturnable tab

摘要

A can top end includes a disc-shaped panel having a disc-shaped flat section an outer periphery to be engaged with an upper end of a can body, and a stay-on type tab attached on the flat section of the panel. The disk-shaped flat section has a primary score to define a primary scored portion surrounded by the primary score and the flat section further includes a secondary score to define a secondary scored portion surrounded by the secondary score. The tab has a connecting portion rotatably connected to a center portion of the flat section around an axis perpendicular to the flat section and the tab has both a pull-up end and a push-down end. The primary scored portion is located below the push-down end of the tab to enable the primary scored portion to be opened by pulling up the pull-up end of the tab. The secondary scored portion is located at a position facing the push-down end of the tab when the tab is rotated to a predetermined angle from an initial position, so that the secondary scored portion is opened by pulling up the pull-up end of the tab.
