Abstract
Abstract A package for carryout foodstuffs or the like is prepared from the combination of an open ended tray and a cooperating outer protective bag. The tray is prepared from a single blank of paperboard or the like and is secured in its assembled condition with friction locks thereby obviating the need for glue, staples or other securing means. The tray comprises a pair of bottom panels, side walls attached to the bottom panels and an integral partition formed from two divider panels that are connected to the adjacent ends of said bottom panels. The outer bag is adapted to enclose the tray and its contents for delivery.
