Abstract
An easy open can end has an improved structure for facilitating the opening operation of the tear panel, a method of further forming a can end to have the improved structure, and tooling for accomplishing the method. The further formation of the can end is particularly useful in easy-open can ends having enlarged tear panels.
Claims10
An easy open can end having improved flow characteristics, said end comprising:
- a circular center panel with a rupturable score line therein, the score line defining the periphery of a non-removable tear panel,
- a non-detachable tab including a nose portion and a rear portion;
- and
- a connection between the tab and the center panel which acts as a pivot about which the tab can be rotated out of the plane of the center 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 center panel to create an opening, the opening including a major axis and a minor axis, the minor axis located at a diameter of the center panel and the major axis located perpendicular to said diameter, the diameter of the center panel is less that 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 of between about 1.5 and 1.7.
