EASY-OPEN CONTAINERS

摘要

The scored side wall of a can body (110) or a large aperture tear-open can end (20) has a removable portion (26) defined by a score line (27) which is covered by a band or annulus (28) of polymeric or other material bonded to the side wall or can end at both sides of the score line so that after seaming of the can end onto a can body (17) the score line may be broken without disruption of the hermetic seal provided by the polymeric annulus. The polymers chosen for the annulus are easier to tear than scored metal. The removable portion of the body or can end is opened either by fracture of the polymeric annulus or peeling of the removable portion away from the annulus.
