Abstract
A closure assembly for an open-top container including an adapter ring with a depending groove for engagement about the rim of the container. The adapter ring further includes a pair of integral hinge seats having opposed detents which receive and rotationally position a pair of pivot pins integral with an overlying cover. Each pivot pin includes a detent-received shaft portion for rotational manipulation of cover, and a cam selectively engageable with a second detent in the open position of the cover for retention of the cover. The pin cam, in the corresponding detent recess, provides a second pivot axis for complete disengagement of the cover.
