Small diameter can end with large opening

An easy open can end comprising a circular centre panel with a rupturable score line therein, the score line defining the periphery of a non-removable tear panel,

• a non-detachable tab having a nose portion and a rear portion, and
• a connection between the tab and the centre panel which acts as a pivot about which the tab can be rotated out of the plane of the centre panel,
• such that in use, the rear portion of the tab is lifted to cause the nose portion of the tab to press down on the tear panel, thereby rupturing the score line and swinging the tear panel out of the plane of the centre panel to create an opening,
• the opening having a major axis and a minor axis, the minor axis located on a diameter of the centre panel and the major axis located perpendicular to said diameter,
• characterised in that
• the diameter of the centre panel is less than 1.835 inches (46.6 mm) and the opening has an area of less than 0.5 square inches (323 mm2) and an aspect ratio (major axis:minor axis) of between 1.3 and 1.7.
