Abstract: A can for containing a liquid has a top end having a dispense area defined by a first score line and a pull tab coupled to the top end by a rivet. The pull tab has a puncturing end for breaking the first score line and pushing into the interior of the can without detaching the dispense area to open a dispense aperture. A vent area is defined by a second score line and positioned on the opposite side of the rivet. The first and second score lines are separated by at least one torsion stripe of the can top material for acting as a hinge by torsion upon lifting the actuating end of the pull tab. As the dispense aperture is opened by pushing the dispense area into the interior of the can, a vent aperture is opened by pulling the vent area outwards.

Abstract: A can for containing a liquid has a top end. The top end has a dispense area defined on the top end by a first score line and a vent area defined on the top end by a second score line separate from the first score line. The top end has a first rivet located between the vent and dispense areas for coupling to the top end. The top end has a pull tab suitable for puncturing the dispense areas to open a dispense aperture. The top end has a device for opening the vent aperture. The dispense area has a dimension along the diameter of the top end passing by the first rivet greater or equal to the radius of the top end.

Abstract: A can for containing a liquid having a top end with (a) a dispense area defined by a first score line and (b) a pull tab coupled to the top end by a first rivet. The pull tab punctures the dispense area to open a dispense aperture upon lifting an actuating end of the pull tab. The top end has (c) a vent area defined by a second score line and (d) a secondary lever coupled to the top end by a second rivet, and has a puncturing end for puncturing the vent area to open a vent aperture upon lifting an opposite, actuating end of the secondary lever. The secondary lever and pull tab interlock so lifting the actuating end of the pull tab triggers lifting of the actuating end of the secondary lever, opening both dispensing and vent apertures in a single movement.

Abstract: Over the years there have been numerous attempts to improve the can lid oftentimes found on aluminum beverage can lids. The aims have traditionally been to reduce costs and improve performance. These aims have been accomplished through a variety of means, such as creating different formations within the can lid to reduce the amount of metal used while maintaining performance levels. Here, step portions are utilized between the annular countersink and the center panel of the can lid that cause a curvature of the center panel or to simply provide an angled inside wall. These formations, thus, reduce the amount of metal used while maintaining quality and yielding the desired performace.

Abstract: A preferred embodiment of the disclosed can lid has a center panel having a central axis that is perpendicular to a diameter of the outer rim, or peripheral curl portion, of the can lid, an annular countersink surrounding the center panel, an arcuate portion extending radially outward from the annular countersink, a step portion extending radially upward and outward from the arcuate portion, a first transitional portion extending radially outward from the step portion, a second transitional portion extending radially outward and upward from the first transitional portion, and a peripheral curl portion extending outwardly from the second transitional portion.
