Originality-ensuring device for container closures

For use with a container having a neck which defines an opening of the container and which defines an axis and having a shoulder which projects from the neck in a generally radial direction relative to the axis and with a container closure which is capable of being applied to the neck of the container so as to close the opening of the container, an originality-ensuring device comprising an indicator element which is subdivided by predetermined breaking points into individual segments and which is adapted to be arranged around the neck of the container, between the shoulder of the container and the container closure, and which is arranged to be stressed therebetween by closing movement of the container closure, the indicator element being configured so that, when the indicator element is arranged around the neck of the container, between the shoulder of the container and the container closure, the predetermined breaking points remain unbroken until the indicator element is stressed therebetween by closing movement of the container closure, whereupon the predetermined breaking points are destroyed and the consequently individually separated segments are held in a firmly clamped-in manner between the container closure and the shoulder of the container.
