Claims
- 1. In a tray for use in a food preparation unit having a plurality of pairs of cantilevered support arms with a heater shelf secured to each pair of support arms and with the tray slidably positioned on each heater shelf, the tray comprising a generally flat element with a generally planar upper surface and with a leading wall and an oppositely disposed trailing wall and a pair of side walls opposite each other and intermediate said leading wall and said trailing wall, the improvement being said tray having at least one dish size opening extending through said element whereby a dish to be heated may be inserted therein and rest upon a heater on the heater shelf disposed beneath said tray, a raised edge around the perimeter of said upper surface along at least said leading wall and said trailing wall, and a pair of notches extending completely across said raised edge along said leading wall thereof and spaced inwardly from said side walls whereby said tray may be slid on the heater shelf and the pair of cantilevered support arms for the heater shelf thereabove may be disposed in said notches.
- 2. The tray of claim 1 wherein said raised edge along said trailing wall is upstanding and solid and free of notches in line with said notches of said leading wall to prevent said trailing wall to be inserted on said heater shelf before said leading wall is inserted.
- 3. The tray of claim 1 wherein a pair of notches are disposed across said raised edge along said trailing wall in line with said notches across said leading wall.
- 4. The tray of claim 1 wherein said notches are uniformly disposed away from said side walls by the same distance thereof.
- 5. The tray of claim 1 including positioning ribs extending downwardly away from said upper surface and below said walls and being disposed away from said side walls by generally the same distance as said notches for fitting in detents in the heater shelf.
- 6. The tray of claim 5 wherein said ribs are integral with each other and are located adjacent to and parallel to said leading wall.
- 7. The tray of claim 1 including a pair of depressions in said element, each of said depressions extending below said walls and being located between each respective notch and its respective side wall, and said depressions having rounded shoulders curved toward each other at said leading wall.
- 8. The tray of claim 7 wherein said depressions further comprise dish supporting indents.
- 9. The tray of claim 1 including a pair of depressions in said element, each of said depressions extending below said walls and being located between each respective notch and its respective side wall, and said depressions having side edges generally parallel to said side walls.
- 10. The tray of claim 9 wherein said depressions further comprise dish supporting indents.
- 11. The tray of claim 1 wherein a raised circumferential bead is around each dish size opening for supporting a dish having a circumferential notch around the lower portion of the dish, an elongated curved slot extending through said element whereby a menu may be inserted therein, and a plurality of dish receiving indents formed in said upper surface.
- 12. The tray of claim 11 including a plurality of said dish size openings, said raised edge extending completely around said upper surface except for said notches, and said notches being equally spaced from said side walls.
- 13. In a tray for use in a food preparation unit having a plurality of pairs of cantilevered support arms with a heater shelf secured to each pair of support arms and with the tray slidably positioned on each heater shelf, the tray comprising a generally flat element with a generally planar upper surface and with a leading wall and an oppositely disposed trailing wall and a pair of side walls opposite each other and intermediate said leading wall and said trailing wall, the improvement being said tray having at least one dish size opening extending through said element whereby a dish to be heated may be inserted therein and rest upon a heater on the heater shelf disposed beneath said tray, a dish supporting indent disposed adjacent each side wall, each dish supporting indent comprising a depression extending below said walls and having a rounded shoulder disposed toward the rounded shoulder of the other depression in the general area of said leading wall, and each depression further having a side edge extending from its rounded shoulder parallel to said side wall and disposed toward the side edge of the other depression whereby said depressions are disposed laterally beyond the cantilevered support arm for its heater shelf.
- 14. The tray of claim 13 including positioning ribs extending downwardly away from said upper surface and below said walls slightly inwardly of said side edges of said depressions for fitting in detents in the heater shelf.
- 15. The tray of claim 14 wherein said ribs are integral with each other and are located adjacent to and parallel to said leading wall.
- 16. The tray of claim 15 wherein a raised edge is disposed around the perimeter of said upper surface along at least said leading wall and said trailing wall, a pair of notches in said raised edge along said leading wall thereof, and said notches being disposed slightly inwardly of said side edges of said depressions.
- 17. The tray of claim 13 wherein said tray is free of any other depression in line with each of said side edges, and each depression side edge and rounded shoulder being a mirror image of the other depression side edge and rounded shoulder and being located the same distance from its respective side wall as the other depression side edge and rounded shoulder is located from its respective side wall.
