ABSTRACT:
This invention relates to a pivotal closure for a container. The closure structure includes a collar defining an opening, and associated with the opening is a lid mounted for rotation about an axis generally coaxial with this opening. This lid is further mounted for pivoting about an axis normal to the axis of rotation between a closed position in which the lid closes the opening and an open position in which an aperture defined by the lid and/or the collar allows access through the opening. The rotation of the lid is governed by a cam mechanism operable by pivoting movement of the lid. The can mechanism is, generally, a saw-tooth cam surface associated with either the collar or the lid and a cam follower associated with either the collar or the lid, so that pivoting the lid from a closed position through an open position and back to a closed position causes the lid to rotate about the axis of the opening by an amount determined by the cam surface.
