Abstract: A lever-actuated closure for bottles or the like containers is described which closure comprises a closing member sealingly mountable on an outlet orifice of the container, an actuating member having a manually operated gripper part and being hingedly mounted below the outlet orifice, and a connecting member hingedly attached to the actuating member and to the closing member at the outside thereof, which closure can be transferred, by means of the actuating member, from an open position, in which the closing member frees the outlet orifice, through elastic deformation of at least one of the parts of the closure via a dead-center position, in which the hinge axis of the actuating member and the two hinge axes of the connecting member are in a common plane, into a closed position, in which the closing member seals the outlet orifice, or vice versa from this closed position into the open position, the gripper part of the actuating member being, in the closed position, above the elastically deformed closing membe
