Abstract
An end closure for a container for grated or powered products having a push open lid portion for providing access to material within the container and a rotatable closure portion for selectively closing off the opening defined by the push open lid portion. The push open lid portion includes elements on the openable lid portion which cooperate with corresponding gripping elements defined on the undersurface of the end closure so the latter will engage the former to retain the lid portion in its open disposition.
