Abstract
A food service tray for a thermalization cart is injection molded as a one-piece integral tray. The tray includes a plurality of integral compartments some of which are for the placement of food items that are going to be heated (a heatable or hot compartment), the other compartments of which are for the placement of food items that will remain cold (a cold compartment). The bottom wall of each of the heatable compartments is of less thickness than the bottom wall of each of the cold compartments. Additionally, the upper surfaces of the bottom walls of each of the heatable compartments are in a first common plane that is coplanar to a second common plane formed by the bottom surfaces of the bottom walls of each of the cold compartments. Therefore, the bottom surfaces of the bottom walls of the heatable compartments are naturally in a third common plane that is axially below the second common plane. The tray includes integrally molded supporting webs or gate bosses between the heatable compartments to provide rigidity and integrity to the tray due to the variable thickness bottom surface of the tray.
