Abstract
A pressurized container end has a frangible member covering an opening in the end. The frangible member is cut away from the end by the action of increased pressure from within the container against the member. A protrusion in a portion of the end is depressed into the container for increasing pressure in the container. In an alternate form of the invention, the container itself is depressed inwardly for causing the increased pressure sufficient to cut the frangible member away from the end. Various opening geometries are each formed with a cutting edge.
Claims21
An easy open container comprising:
- a pressurized container;
- a panel affixed to the pressurized container, the panel having an opening for passing contents of the container therethrough, the panel further having a cutting edge portion adjacent the opening, the cutting edge portion extending into the container;
- a frangible member across the opening of the panel, the frangible member biased against the cutting edge portion;
- and
- means for increasing pressure within the pressurized container, wherein the increased pressure causes rupture of the frangible member outwardly from the container and away from the panel.
An easy open end for a pressurized container comprising:
- an end panel having an opening, the panel further having a cutting edge portion adjacent the opening for extending into a container;
- a frangible member across the opening and biased against the cutting edge portion;
- and
- means for increasing pressure against the frangible member when the end panel is affixed to a pressurized container, wherein the increased pressure causes rupture of the frangible member outwardly from the container and away from the panel.
A method for easily opening a container, the method comprising the steps of:
- providing a pressurized container having an edge for affixing a panel thereto;
- providing a panel for affixing to the pressurized container edge, the panel having an opening for passing contents of the container therethrough;
- providing a cutting edge portion adjacent the opening;
- extending the cutting edge portion into the container;
- placing a frangible member across the opening of the panel;
- biasing the cutting edge portion against the frangible member;
- affixing the panel to the container edge;
- and
- increasing pressure within the pressurized container for rupturing the frangible member outwardly from the container and away from the panel, thus providing access into container through the panel opening.
