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.

Dependent claims

A closure for a container having an access opening thereinto, said closure comprising:

a collar surrounding said opening into said container;
a lid member rotatably mounted within said collar for rotation about an axis of rotation coaxial with the axial center of said collar, said lid member further being pivotable between open and closed positions about a pivotal axis normal to said axis of rotation, said lid member having an aperture therethrough which is accessible when said lid member is pivoted in the open position, whereby access into said container through said aperture is possible;
camming means between said lid member and said collar for controlling the pivoting and rotational movement of said lid member within said collar, said camming means being comprised of:
a saw-tooth cam surface around the inside surface of said collar;
a cam follower on said lid member movable along said cam surface, whereby pivoting said lid member causes said cam follower on said lid member to move across said cam surface, thereby rotating said lid member about said axis of rotation.
