Abstract (en)
[origin: WO9413544A1] An easy open end suitable for a food or beverage can, having a tab (60, 160) attached to a central panel (10, 130) of the end and a main score line (50, 150). A part (65, 165) of the tab overlies a protrusion (80, 180) in the end, the protrusion having an associated vent score line (90, 190). When the tab is raised, the vent score line breaks before the main score line as the tab engages the protrusion, thereby allowing venting prior to rupture of the main score line. In an alternative embodiment, a protrusion is formed in the tab instead of, or in addition to, in the central panel.
