ABSTRACT:
A telescopic carton assembly for compact shipment and storage of envelopes and the like which is readily converted and separated into two self-contained shipping containers with about twice the load-carrying capacity of the telescopic carton assembly. The convertible carton assembly is particularly useful in connection with pre-sorted mail and includes a pair of telescoping cartons. Each of the cartons has an outer panel with upright walls and a movable flap assembly for converting the carton from a portion of the telescopic carton assembly to a self-contained shipping container. Preferably, the movable flap assembly includes a movable panel and a pair of pivotable flaps. The movable panel and one of the flaps are positioned adjacent the outer panel within the interior of the carton when the carton is being used as part of the telescopic carton assembly. The other pivotable flap cooperates with the movable panel to provide the top of the carton when the carton is separated from telescopic engagement with the other carton during use of the carton as a self-contained shipping container.
