ABSTRACT:
A stackable articulated carton tray apparatus for flat food products, particularly pizza pies, capable of being stacked in multiple quantities upon one another such that the bottom panel or an upper carton apparatus forms the cover for the adjacent lower carton apparatus. The carton apparatus is further joinable in a manner so as to prevent the shifting and separation of the stacked carton apparata during transport. The carton apparatus includes an octagonal bottom panel, side walls and detachable top panel for the uppermost one of several carton trays. Emanating from the side walls are alignment and interlock flaps for aligining and releasably joining multiple ones of the carton tray apparatus in a stacked configuration.
