Abstract: A closing device for containers is made of plastic with a tiltable lid linked to a lid support to be attached to the lid or to the container where it can be moved via a hinged connection from a closed position to an open position. The closing device also has a spring on one side of the lid, and a lid support or the container on the other side. The spring is arranged with respect to the tilting axis of the lid which is defined by the hinged connection such that the lid is displaced from the closed position to the open position after having passed a dead center position, due to the pre-stress of the spring. The lid and the lid support or container each have at least one integrally linked abutment. The abutments come into contact with each other in the open position of the lid as a result of being urged into the contact position by the spring.

Abstract: A one-piece closure for dispensing product from a container has a cap secured to the container and a lid connected to the cap by a support arm through an integrally molded hinge. The support arm is pivoted by the hinge between a pair of upstanding projections on the end wall of the cap. Ribs projecting laterally from the support arm engage the projections to maintain the lid opened when the container is inverted to dispense product. When the lid is pushed closed, the ribs deform to allow the support arm to pass between the projections. In one embodiment, side edges of the ribs engage upwardly facing cylindrical camming surfaces on the projections. In another embodiment, the outer surfaces of the ribs engage confronting flat surfaces on the two projections. In the closed position of the lid, the ribs in both embodiments are received in recesses in the projections so that they do not become permanently deformed and loose their effectiveness over time.
