ABSTRACT:
A plastic snap hinge having a lower part and a cap connected to each other by a single or multi-part main hinge and a flexible element which generates a snap action. The flexible element is connected to the lower part and the cap by film hinges integral with the lower part and the cap. The flexible element has a shape which is folded repeatedly and which is such that a straight line penetrating the flexible element intersects the flexible element at least at three points. The construction allows the design of plastic tops with a flat, cap having an extremely large angle of opening and a strong snap action.
