Easy open closure with improved pressure performance
摘要:
An easy open closure (10) for food or beverage containers and comprising a centre panel (27) surrounded by a circumferential score (16) and an outer seaming panel (17). The closure further comprises a tab (11), the tab being fixed to the centre panel by a rivet (12) formed in the centre panel (27) such that lifting of a radially inner region of the tab (11) forces a nose portion (24) of the tab into contact with a region of the centre panel adjacent to a radially inner edge of the circumferential score (16), thereby causing the score to fracture. A bead (19) is formed in and extending circumferentially around the centre panel inside and adjacent to the circumferential score (16) and at a radius outside of the rivet (12), the bead deviating inwardly from its circumferential path as it approaches the region in which the rivet (12) is formed, and the bead terminating adjacent to and on either side of the rivet.
