ABSTRACT:
A closure is provided for a container. The closure has a body for being mounted over the container opening and defines an orifice for communicating through the container opening with the container interior. The body also defines a pair of spaced-apart bearing cavities. A compression member has distal first end and a second end. The first end is adapted to engage a rear abutment wall of the body, and the second end is pivotally connected to the lid at a location spaced from the trunnion axis. Each bearing cavity has a clearance on opposite sides of the trunnion received therein when the lid is in the full closed position. The compression member length is such that the distal first end is spaced from the body rear abutment wall when the lid is in the full closed position.
