Abstract

A stackable food and beverage service tray includes a substantially planar tray bottom and a sloping side wall extending upwardly and outwardly from an inner peripheral edge of the tray bottom so as to surround said tray bottom. The tray bottom has an upper floor surface and an underside surface. The tray'"'"'s sloping side wall has an inner surface and an outer surface with the side wall'"'"'s outer surface adjoining the tray'"'"'s underside surface at a peripheral bottom edge of the tray. A raised rib is provided on the inner surface of the sloping side wall. Feet are also provided on the tray'"'"'s underside surface along the bottom edge of the tray. The tray'"'"'s raised rib and feet cooperate to define a space between stacked trays through which air can flow to facilitate drying of the stacked trays after they have been washed.

A stackable food and beverage service tray as claimed in claim 1 wherein said feet of a second said tray cooperate with said inner surface of said side wall of a first said tray so that when a said second tray is stacked on a said first tray said inner surface of said side wall of said first tray automatically directs said feet of said second tray onto said rib of said first tray so that said second tray is centered on said first tray.

3. A stackable food and beverage service tray as claimed in claim 1 wherein said raised rib extends along said inner peripheral edge of said tray bottom.

4. A stackable food and beverage service tray as claimed in claim 1 wherein said tray is generally rectangularly shaped with four corners and wherein said feet are located along said bottom edge of said tray at each corner of said tray.

5. A stackable food and beverage service tray as claimed in claim 1 wherein said sloping side wall in the area defining said opposing first and second openings on opposite sides of said tray has a height which is greater than it is in any other area of said tray.

6. A stackable food and beverage service tray as claimed in claim 1 wherein said sloping side wall terminates at an outer peripheral edge which is shaped so as to form an easily gripped bead.

7. A stackable food and beverage service tray as claimed in claim 6 wherein said tray bottom lies in a plane and said bead has a generally oval shaped cross section with a longitudinal axis and wherein said bead disposed relative to the plane of said tray bottom so that the longitudinal axis of said oval-shaped bead forms a 45 degree included angle with said plane of said tray bottom.

8. A stackable food and beverage service tray as claimed in claim 6 wherein said bead extends around the entire outer peripheral edge of said sloping side wall of said tray.

9. A stackable food and beverage service tray as claimed in claim 1 wherein said upper floor surface of said planar tray bottom is provided with first surface features for engaging second surface features of tray items placed on said tray bottom to prevent said tray items from sliding on said tray bottom.

10. A stackable food and beverage service tray as claimed in claim 9 wherein said first surface features are serpentine-shaped ribs and valleys.

11. A stackable food and beverage service tray as claimed in claim 1 wherein said sloping side wall on one side of said tray has a height which is less than that on the opposite side of said tray.

12. A stackable food and beverage service tray as claimed in claim 1 which is injected molded and of unitary construction.

13. A stackable food and beverage service tray comprising:

a substantially planar tray bottom having an upper floor surface and an underside surface; and

,

a sloping side wall extending upwardly and outwardly from an inner peripheral edge of said tray bottom so as to surround said tray bottom, said sloping side wall having an inner surface and an outer surface wherein said outer surface adjoins said underside surface at a peripheral bottom edge of said tray and said inner surface adjoins said upper floor surface of said tray bottom at said inner peripheral edge of said tray bottom, said sloping side wall further defining opposing first and second openings on opposite sides of said tray, each said opening having a lower half extending toward said inner peripheral edge of said bottom tray and wherein said openings serve as handles for gripping said tray, said sloping side wall further defining opposing first and second dams on opposite sides of said tray, said first dam defining a first generally vertical inner surface which surrounds the lower half of said first opening and extends towards said inner peripheral edge of said tray bottom, said second dam defining a generally second vertical inner surface which surrounds the lower half of said second opening and extends towards said inner peripheral edge of said tray bottom and wherein said dams serve to contain liquids spilled on said tray floor surface.

14. A stackable food and beverage service tray as claimed in claim 13 wherein said outer surface of said sloping side wall also defines first and second dam receiving sections so that when a second said tray is stacked on a first said tray said first and second dam receiving sections of said second tray receive said first and second dams of said first tray, said dams and dam receiving sections further being sized and configured so that they are prevented from substantial contact with each other when said first and second trays are stacked, said dams and dam receiving sections of stacked trays thereby defining a space between each other through which air can flow to facilitate the drying of said stacked trays after they have been washed.
