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.

A can for containing a liquid and comprising a top end, said top end comprising:
- (a) a dispense area defined on said top end by a first score line;
- (b) a pull tab coupled to the top end by a rivet, said pull tab comprising a puncturing end suitable for breaking the first score line and pushing into the interior of the can, without detaching the dispense area, to open a dispense aperture upon lifting an opposite actuating end of said pull tab away from the top end;
- and
- (c) a vent area defined on said top end by a second score line separate from the first score line and generally positioned on the opposite side of the rivet to the first dispense area;
- wherein the first and second score lines are separated from one another by at least first and second torsion stripes of the can top material suitable for acting as hinges by torsion upon lifting the actuating end of the pull tab away from the can top, such that 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 from the can top end;
- wherein the rivet is disposed at the center of the top end of the can.
A can for containing a liquid and comprising a top end, said top end comprising:
- (a) a dispense area defined on said top end by a first score line;
- (b) a pull tab coupled to the top end by a rivet, said pull tab comprising a puncturing end suitable for breaking the first score line and pushing into the interior of the can, without detaching the dispense area, to open a dispense aperture upon lifting an opposite actuating end of said pull tab away from the top end;
- and
- (c) a vent area defined on said top end by a second score line separate from the first score line and generally positioned on the opposite side of the rivet to the first dispense area;
- wherein the first and second score lines are separated from one another by at least two torsion stripes of the can top material suitable for acting as hinges by torsion upon lifting the actuating end of the pull tab away from the can top, such that as the dispense aperture is opened by pushing the dispense area into the interior of the can, a vent aperture is simultaneously opened by pulling the vent area outwards from the can top end;
- and
- wherein the rivet is disposed at the centre of the top end of the can.
A can for containing a liquid and comprising a top end, said top end comprising:
- (a) a dispense area defined on said top end by a first score line;
- (b) a pull tab coupled to the top end by a rivet, said pull tab comprising a puncturing end suitable for breaking the first score line and pushing into the interior of the can, without detaching the dispense area, to open a dispense aperture upon lifting an opposite actuating end of said pull tab away from the top end;
- and
- (c) a vent area defined on said top end by a second score line separate from the first score line and generally positioned on the opposite side of the rivet to the first dispense area, the second score line comprising first and second ends;
- wherein the first and second score lines are separated from one another by at least two torsion stripes of the can top material suitable for acting as hinges by torsion upon lifting the actuating end of the pull tab away from the can top, such that 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 from the can top end;
- wherein an additional torsion stripe extends between the first and second ends of the second score line;
- and
- wherein the rivet is circumscribed within the second score line and the additional torsion stripe.
