ABSTRACT:
A beverage can end of drawn metal is provided with a lipped opening upstanding from the expansion panel of the end. The expansion panel may be convex, flat or concave. The lipped opening is proportioned to facilitate drinking and pouring from a can. A height of the lip of 0.25 inches is sufficient for this purpose. The lip is formed as a circular wall with a pushdown gate positioned within the lip, the gate being mounted on a seating and hinging means which preferably is a triplefold of drawn metal. The hinging and seating means within the lip is of a smaller diameter than the lip wall, and is supported by a bridging means connecting with the top of the lip wall. The bridging means includes a circular panel and may include an inner wall portion. In a first embodiment, the circular panel is the top of the lipped opening and the seating and hinging means is at the base of an inner wall, whose top is at the inner edge of the circular panel to space the inner wall from the outer wall. In a second embodiment, the inner wall is not present and the seating and hinging means is at the inner edge of the circular panel and at the top of the lipped wall. In a third embodiment, an inner wall is closely adjacent to the top portion of the lip wall and a circular spacer panel extends inwardly from the bottom of the inner wall to carry the seating and hinging means at its inner edge.
