ABSTRACT:
A new and novel tray for storing and reheating frozen food. The base portion of the tray is formed in a one-piece construction having spaced apart hollow side walls and double thickness end walls both side and end walls being adhesively secured to the underside of the tray. Corner web-like folds positioned between inner panels of the side and end walls are held in place by securing flaps on the outer panels and are secured to the tray. The folding of the side walls and end walls in combination with the corner web-like folds makes the interior portion of the tray leakproof. A separate one-piece lid may be adhesively secured to the top of the hollow side walls and to the sides of the end walls to enclose the tray and make a completely leakproof package. In the preferred embodiment the tray and lid of the package are formed generally of paperboard and may be coated with desirable coatings. The package may also be formed with foil laminations on one or both sides thereof.
