Abstract
Full-aperture easy-open metal can-end for a can of the lift-up type with a tab, having an endless score-line close to its outer circumference of the can-end, wherein the removable part is profiled with a plurality of terraces at different heights, including an outer terrace close to the outer circumference of the can-end, an innermost terrace and at least one intermediate terrace. Adjacent terraces merge into one another with a height transition. To achieve low tear-force and/or other advantages, the intermediate terrace is inclined in a direction opposite to that of the outwardly adjoining transition at an angle .alpha. in the range 3 to 20 degrees to a plane perpendicular to the can axis.
