15. A closure for a container opening, the closure comprising
a body for mounting to the container over the opening, and defining a discharge aperture communicating with the opening, a flip-top cap mounted for movement on the body between a closed position on the body to cover the aperture and an open position away from the body to expose the aperture, and a hinge formed to include vault means for vaulting the flip-top cap from an opened position away from the body to a closed position on the body to assist in aligning the flip-top cap with the body when flip-top cap is moved onto the body and to cause accelerating movement of the flip-top cap relative to the base in response to the application of a force to the flip-top cap to cause the flip-top cap to move past an over-center position.
