ABSTRACT:
A packaging of plastic material includes a cup or dish-shaped container and a cover that can be used to re-close the container after it has been opened for the first time. An indicator is provided to indicate an original sealed status of the container. The indicator includes at least one peg that is arranged and molded on the container and/or on the cover as an integral part thereof, and which, when the cover is installed on the container in the original sealed state, protrudes through a corresponding opening in the other of the container and the cover, and is riveted at its free end.
