- a cylindrical portion with an exterior surface and a shoulder; and
- a circular end portion, said circular end portion terminating in an annular precurled lip rolled back on itself to secure the precurled lip to the exterior surface of the cylindrical portion wherein the circular end portion overlays the shoulder of the cylindrical portion;
- the circular end portion further including an annular recessed rim adjacent the lip and an annular shoulder adjacent the rim; the circular end portion having a channel extending across the rim and the shoulder of the cylindrical portion effective for releasing gas from the can while substantially preventing the release of liquids from the can when the end portion is annularly secured to the exterior surface of the cylindrical portion.
