Abstract
A plastic closure having a lower part attachable to a container, and a cap which is connected with the lower part by a main film hinge. A spring element engages the lower part and the cap, and also bridges an axis of rotation of the main film hinge and thus generates a snap effect. The main film hinge extends continuously through an area in which the main film hinge is bridged by the spring element. In a closed state of the plastic closure, each spring element is hidden completely within the closed closure.
