ABSTRACT:
An easy opening beverage can wherein the closure is of the push-in type. The dispensing opening in the container is defined by a sealing ring into which there is engaged a peripheral flange of the closure member with the closure member being held initially with respect to the sealing ring only by a mechanical interlock. Pressure within the can tightly forces the closure member into sealing engagement with the sealing ring and normally prevents removal. A lever is connected to the sealing ring to effect distortion thereof and bleeding-off of pressure from within the can so as to relieve the holding pressure on the closure member, after which the closure member may be readily pushed into the can in an opening action.
