Abstract

A freestanding cover for a food tray has a flange section and a support section extending downwardly from the flange section. The support section supports the cover independently of the tray, with the flange section positioned above the tray opening. The freestanding cover is inserted into a heated compartment in a food warming cabinet and is supported on a retaining mechanism positioned on the shelf of the food warming cabinet. The retaining mechanism, in the form of a wire rack, prevents the cover from moving forward or backward. With the cover retained by the wire rack, a tray containing previously cooked food portions may be inserted into and removed from a receiving space in the cover, leaving the cover inside of the compartment.

Claims

1. A method for maintaining previously cooked food portions in a ready to use condition in a food warming apparatus comprising a cabinet having a heated compartment which has an upper compartment surface and a lower compartment surface, said method comprising the steps of:

providing a wire rack in said heated compartment, said wire rack including a plurality of channel members;

providing a cover, said cover having a flange section and a support section extending downwardly from said flange section, said support section having a plurality of support legs;

placing said previously cooked food portions in a tray, said tray having a tray lip defining a tray opening;

inserting said cover into said heated compartment and placing said support legs of said cover into said channel members of said wire rack to define a receiving space, at least a portion of said flange section being positioned above said receiving space, said cover being retained in said heated compartment by said wire rack; and

inserting said tray into said receiving space.

2. The method of claim 1, further comprising the step of:

positioning said tray in said receiving space such that said flange section blocks said tray opening to restrict evaporation of liquid from said previously cooked food portions.

3. The method of claim 2, wherein said flange section has a flange surface, and wherein said step of positioning said tray in said receiving space includes the step of positioning said tray lip to be substantially flush with said flange surface.

4. The method of claim 1, wherein said cover defines a front opening providing access to said receiving space, and wherein said step of inserting said tray into said receiving space includes the step of inserting said tray into said receiving space through said front opening.

5. The method of claim 1, wherein said cover defines a rear opening providing access to said receiving space, and wherein said step of inserting said tray into said receiving space includes the step of inserting said tray into said receiving space through said rear opening.

6. The method of claim 4, further comprising the step of removing said tray from said receiving space through said front opening.

7. The method of claim 5, further comprising the step of removing said tray from said receiving space through said rear opening.

8. The method of claim 1, wherein the wire rack includes a rectangular frame and the plurality of channel members extend transversely from one end of the frame to the opposite end of the frame.

9. The method of claim 8, wherein the channel members define cavities within the wire rack for accommodating trays, and wherein the step of inserting the tray into the receiving space includes placing the tray into a cavity defined by the channel members.

10. The method of claim 8, wherein the rectangular frame of the wire rack includes at least one front frame member, and wherein the step of inserting the tray into the receiving space includes sliding the tray over the front frame member.

11. The method of claim 9, wherein the step of inserting the tray into the receiving space includes providing a tactile indication that the tray has been placed within the cavity.

12. The method of claim 11, wherein the step of providing a tactile indication includes sliding the tray over the wire rack and moving the tray downwardly into the cavity.

13. The method of claim 10, wherein the cover includes a front lip and a rear lip, and further comprising engaging the front lip and the rear lip of the cover with the tray opening, thereby providing a seal to restrict the evaporation of liquid from said previously cooked food portions.

14. The method of claim 1, further comprising the step of inserting said wire rack into said heated compartment.
