Abstract

Abstract An easy opening end closure for a container in which the end closure includes a panel having a pre-cut pour opening. The pour opening is sealed by a plastic closure having a portion permanently bonded to the underside of the end. A remaining portion is releasably adhered to the underside so that upon downward pressure on the closure, it is released and hinges about the permanently bonded portion. A tongue integral with the panel projects into the opening along the edge along which the flap hinges and is permanently bonded thereto.
