Abstract

A single-piece plastic lid, having a lower part and a cap. The cap is connected to the lower part via a hinge. The lid has a guarantee strip to ensure that the lid cannot be opened unnoticed and that the lid cannot be removed from the container without damaging the guarantee strip. Thus, the guarantee strip has additional elements which enable a positive fit with both the lower part and the neck of the container. Corresponding positive fit elements are also provided on the container neck, for example in the form of snap-in elements.
