Abstract
A closure is provided for use on a container that has an opening communicating with the container interior. The closure includes a body for being mounted to the container over the container opening and for defining at least a first aperture communicating through the container opening with the container interior. The body includes a peripheral side wall outwardly of the first aperture. The closure includes a cover on the body for defining at least a first lid to cover the first aperture. The closure includes a first hinge for accommodating pivoting of the first lid between a closed position occluding first aperture and an open position spaced away from the first aperture and for connecting the first lid directly to another part of the cover or the body. The first lid includes a first engaging arm for engaging the body side wall when the first lid is in the open position. Either or both the first engaging arm and body side wall are resilient whereby the first lid is held in the open position by frictional engagement between the first engaging arm and the body side wall.
