INSULATED FOOD TRAY AND LID THEREFORE ABSTRACT OF THE DISCLOSURE An insulated food serving tray and lid, each of which includes a preformed foam insulator with laterally spaced dish cavities. Each foam insulator is permanently sealed between two preformed panels, one of which has compli- mentary dish cavities. The insulator is of a generally rigid polystyrene bead foam and has a construction fitting around the plural cavities. This construction provides at least a portion of the insulator which is spaced from the preformed panels to reduce internal pressure at peripheral seams joining the panels. Such gap allows the space between the two panels to absorb dimensional variations due to manufacturing tolerance, dimensional changes with temperature, etc. The presence of such gap can be verified by manually squeezing certain areas of the tray or lid after permanently sealing in the insulator. -1-
