Abstract
A food service tray, preferably formed of molded plastic, is particularly adapted to be used in a service cart which can heat food contained in a predetermined 'hot' area of the tray. The tray has a generally flat planar portion from which the side walls of at least one dish-shaped recess extend both upwardly and downwardly. The said at least one dish-shaped recess preferably contains a disposable insert dish and has a bottom surface which is thinner than other portions of the tray in order to facilitate the transfer of heat to food contained in the dish. Integral ribs formed on the lower outer side walls of the recess serve to resiliently and frictionally engage the dish's cover after it has been removed and inverted. In the inverted position, the cover insulates the hot bottom of the tray during serving. The tray preferably also includes a second downwardly recessed portion for cold food, cups and utensils. This second recessed portion extends down further than the said at least one dish-shaped recess by the thickness of the cover.
