A container for packaging frozen food in which the food can be reheated including a paperboard tray having upstanding side walls and horizontal flanges and an upright central divider wall forming separate food compartments in the tray. The container is formed from a planar die-cut blank in which the central divider wall is formed by folding adjacent rectangular panels on the blank into abutting, back-to-back relation and the side walls are one piece and are foldably connected to adjacent die-cut portions of the blank so that when the divider wall is erected, the side walls are continguous to each other about the periphery of the tray. A pre-formed, semi-rigid blister of thermoformable plastic material is used in combination with the tray to provide a leakproof liner.

A compartmentalized container for packaging, storing and heating foods comprising: a paperboard tray formed from a one piece foldable blank having a rectangular base, said base including first and second base members and a central divider wall being of inverted V-shaped configuration, with one side of said central divider wall being hingedly connected to the transverse side of said first base member adjacent thereto, and with the other side of said central divider wall being hingedly connected to the transverse side of said second base member adjacent thereto, with said central divider functioning to define a pair of discrete food compartments on said base; a tubular side wall, said side wall including hingedly connected first and second opposed side wall members and first and second opposed end wall members; said first end wall member being hingedly connected to the other transverse side of said first base member, said second end wall member being hingedly connected to the other transverse side of said second base member, said opposed side wall members being hingedly connected to the opposed longitudinal edges of said first base member; said tray further including a horizontally disposed flange member hingedly connected to the top edge of said tubular side wall and extending perpendicularly therefrom; and a leak proof liner for said paperboard tray preformed from a semi-rigid blister of thermoformable material conforming generally to the interior of said paperboard tray, said blister being sealed to said tray along the flange member. For use in combination with a leak proof liner, preformed from a semi-rigid blister of thermoformable material, a blank for forming a compartmentalized food container comprising a substantially rectangular base, said base including first and second base members of substantially equal width and separated in the longitudinal direction by first and second divider members, with said second divider member being substantially identical in width to said second base member and hingedly connected thereto, with said first divider member being narrower in ‘its’length then said second divider member and hingedly connected along one transverse edge thereto, said first divider member being hingedly connected along the other transverse edge thereof to said first base member, with the opposed longitudinally extending side edges of said first divider member being transversely spaced from the longitudinal sides of said rectangular base, and with said first base member adjacent the opposed longitudinally extending side edges of said first divider member extending to said second divider member, there being a pair of L-shaped cut lines running between said opposed longitudinally extending side edges of said first divider member and said first base member and extending between said first base member and said second divider member to the opposed longitudinal sides of said rectangular base, said cut lines aiding in the erection of said container, said blank further including a pair of opposed end wall members respectively hingedly connected to the opposed transverse sides of said base members; and a pair of opposed side wall members respectively hingedly connected to the opposed longitudinal sides of said first base member, said side wall members extending to a point intermediate the length of said second base member along the longitudinal sides thereof, said blank further including a first pair of opposed flange members respectively hingedly connected to the opposed end wall members, and a second pair of opposed flange members respectively hingedly connected to the opposed side wall members.
