A cabinet type enclosure, for refrigerating a plurality of food items on a plurality of specially configured meal trays has a plurality of thin, generally horizontal, fixedly mounted heater shelf members extending into the enclosed space from one side wall thereof. One or more covered containers of food to be heated are positioned on one side of the trays and are mounted on the trays slightly above the top surface of the tray and with their bottom surfaces in contact with heater plates on the heater shelf members. The meal trays have integral transverse abutment means which cooperate with portions of a container for hot food placed on the tray adjacent the abutment means for preventing longitudinal movement of the hot food container past the transverse abutment means by frictional contact of the container with the heater shelf as the tray is moved into or out of the enclosure and relative to the heater shelf along tray guides. The heater shelf members are preferably sufficiently narrow that they will terminate short of the transverse abutment means. Guide means, which may comprise elongated side runners on the bottoms of the containers and spaced complementary retaining ribs on the tray surface, prevent the containers from rotating as they are moved along the heater shelves. The apparatus is particularly useful for inflight feeding as well as for institutional feeding.

An apparatus for heating at least one covered container on a meal service tray while other items on the tray are refrigerated comprising an enclosed housing having a plurality of cooperative pairs of guide rail portions therein for supporting a first pair of opposed side edges of a plurality of tray

An apparatus for heating at least one covered container on a meal service tray while other items on the tray are refrigerated comprising an enclosed housing having a plurality of cooperative pairs of guide rail portions therein for supporting a first pair of opposed side edges of a plurality of trays; a plurality of vertically spaced, generally horizontal, thin heater shelves extending from a side wall of said housing; a ramp surface on at least one end of each of said heater shelves; a plurality of meal service trays, each of said trays having at least one abutment portion thereon which extends transversely over a portion thereof relative to said first opposed pair of side edges, said abutment portion being located on said tray to permit restraining contact with said at least one covered container relative to the tray while allowing the tray to be slid along one of said plurality of cooperating pairs of guide rail portions so that one of said thin heater shelves will pass above the tray surface and under the container contacted by said abutment portion, and at a spaced horizontal distance from said abutment portion, the ramp surface on each of said heater shelves being adapted to lift a covered container located on said tray adjacent said at least one abutment and permit a flat heater plate portion of said heater shelf with which said container is frictionally engaged to pass under said container as said container is restrained by said at least one abutment portion, said at least one container and said tray and/or said heater shelf having longitudinally extending rib and groove complementary guiding portions thereon for insuring that said at least one container will be restrained from rotational or transverse movement as said container and tray are moved relative to said heater shelf.
