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.
