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.

[ We claim:] [1.] A closing device for containers, said closing device comprising:a lid having a first stopping abutment protruding therefrom;a lid support hingably connected to said lid, said lid support including a second stopping abutment thereupon, said second stopping abutment on said lid support being disposed to engage said first stopping abutment on said lid when said lid is in an opened position;spring means disposed between said lid and said lid support, said spring means being configured to urge said lid toward a closed position with respect to said lid support when an angle between the lid and the lid support is smaller than an angle at which the spring means is at a dead center position, said spring means urging said first stopping abutment on said lid into contact with said second stopping abutment on said lid support in an opening direction of said lid, defining an open position, when the angle between the lid and the lid support is larger than the angle at which the spring means is at the dead center position,wherein said first and second stopping abutments have respective first and second contact surfaces, and wherein a force from the spring means acting upon the lid to swing the lid beyond the dead center position, to said open position, generates a reactive force in a direction which is perpendicular to planes of the contact surfaces.
