Abstract
An easy-open can end for making an opening therethrough suitable for pouring comprises an end plate, a score line in the end plate defining most of the periphery of a tear panel while leaving a hinge, and a protrusion formed on the tear panel. To open the easy-open can end, the protrusion is pressed down by a rotating bar horizontally rotated over the protrusion or by a body vertically hitting the protrusion to cause relative vertical movement between the tear panel and the remainder of the end plate, rupture of the score line, and swinging of the tear panel down about the hinge to an open position.
Claims13
An easy-open can end for making an opening therethrough comprising
- an end plate;
- a score line in the end plate defining a tear panel, while leaving between the tear panel and the remainder of the end plate a hinge, wherein the score line extends away from one end of the hinge, around a bight, and back to the other end of the hinge;
- a protrusion formed on the tear panel wherein the protrusion is used for being pressed down by a rotating bar horizontally rotated over the protrusion to cause relative vertical movement between the tear panel and the remainder of the end plate, rupture of the score line, and swinging of the tear panel down about the hinge to an open position;
- and
- an extended wall encircling the end plate and defining a rotating space, wherein a circular opening of the extended wall is narrower than a circular bottom of the extended wall, the rotating space is used for containing the rotating bar, and the extended wall is used for confining movement of the rotating bar.

- an impression formed on the end plate with a slope on the tear panel and a main part on the remainder of the end plate wherein the impression is used for containing a downward protrusion of a rotating bar that is horizontally rotated over the tear panel from the slope to press down the tear panel to cause a relative vertical movement between the tear panel and the remainder of the end plate, rupture of the score line, and swinging of the tear panel down about the hinge to an open position;
- and
- an extended wall encircling the end plate and defining a rotating space, wherein a circular opening of the extended wall is narrower than a circular bottom of the extended wall, the rotating space is used for containing the rotating bar, and the extended wall is used for confining movement of the rotating bar.
