<p>A dispensing closure having a base ring (16) with means for attachment to a container which permits rotation of the ring without axial movement. A lid (18) is connected to the base ring by a hinge (20) which allows the lid to be swung from a closed position blocking access to a container opening to an open dispensing position. A cam element (30) on the lid effects initial movement of the lid towards an open position when the base ring is rotated. The lid cam element cooperates with a cam surface (24) on the container. A fitment can also be used to attach the closure to a flat can top or to other container configurations. When a fitment is used, the cam surface will be on the fitment rather than the container.</p> |
