ABSTRACT:
A staging cabinet and tray combination especially for use with hamburger buns has an open front cabinet including solid metallic top, bottom, back and side walls abutting each other at right angles and having a plurality of horizontal ledges secured to the side walls at selected vertical intervals, the ledges on one side wall being at the same height as the corresponding ledges on the other side wall. Cooperating with the ledges are trays each supportable at a selected height in the cabinet by a pair of the ledges. Each tray includes a rectangular metallic sheet having downturned flanges along opposite side edges of the sheet, the flanges being slidable on the ledges and being bottom notched to reduce heat transfer and allow air flow. The rectangular sheet itself has ribs along the transverse front and rear edges, each rib having an inner wall upstanding from the sheet and then having an outer wall extending downwardly from the inner wall far enough to afford a gripping portion. The sheet also has upstanding from its upper surface a plurality of grouped bosses for supporting buns, each of the bosses preferably having a central perforation. The entire arrangement is designed to permit free circulation of temperature equalizing air and to minimize heat transfer from one portion to the other of the metallic assembly.
