ABSTRACT:
A carton with a hinged cover formed from plastic sheet material has a locking device which comprises a continuous, rigid locking member formed integrally with the bottom section of the carton which extends upwards from the bottom section with a forward-facing extension on the top for engaging with corresponding locking apertures formed in the cover. The cartons are particularly useful for packaging eggs since they permit eighteen-cell carton to be packed on conventional packaging equipment normally used for twelve-cell cartons.
