Abstract

A food display including a container for holding a product and having at least one translucent portion that facilitates viewing the product from outside the container, a sign panel that is coupled to the container and is at least partially translucent, and a light assembly that includes a light source positioned to provide light to both the container and the sign panel. Preferably, the sign panel and the light source are both positioned above an upper plane of the container to facilitate backlighting the sign panel. The food display may further include a fan positioned above the upper plane of the container, and an air circulation system that circulates air within the container. In one embodiment, the container includes a conduit, such as a hollow corner post that supports a side panel of the container, extending from the upper portion to the lower portion.

Claims

1. A food display comprising:

a container for holding a product and having at least one translucent portion that facilitates viewing the product from outside the container, the container defining an upper plane;

a fan positioned above the upper plane and defining a gap between the fan and the upper plane;

a sign panel coupled to the container and being at least partially translucent; and

a light assembly including a light source positioned in the gap to provide light to both the container and the sign panel.

2. The food display of claim 1, wherein the container includes a door for accessing the interior of the container.

3. The food display of claim 2, wherein the door includes a translucent portion that facilitates viewing the product through the door.

4. The food display of claim 1, wherein the container includes multiple translucent portions that facilitate viewing the product from outside the container.

5. The food display of claim 1, wherein the container defines an upper plane, and the sign panel is positioned above the upper plane.

6. The food display of claim 1, wherein the container defines an upper plane, and the light source is positioned above the upper plane.

7. The food display of claim 1, wherein the light source is generally horizontally aligned with the sign panel.

8. The food display of claim 1 further comprising:

a fan coupled to the container; and

a circulation system for circulating gas provided by the fan, the circulation system including a gas inlet port and a gas outlet port, one of the ports being positioned adjacent an upper portion of the container and the other of the ports being positioned adjacent a lower portion of the container.

9. The food display of claim 8, wherein the container includes a conduit extending from the upper portion to the lower portion.

10. The food display of claim 9, wherein the container includes a translucent side panel and a corner post that supports the side panel, wherein the corner post is hollow and acts as the conduit.

11. A food display comprising:

a container for holding a product and having at least one translucent portion that facilitates viewing the product from outside the container, the container including a translucent side panel and a hollow corner post supporting the side panel;

a conduit defined by the hollow corner post extending substantially from an upper portion of the container to a bottom portion of the container and including an air inlet and an air outlet, wherein one of the air inlet and the air outlet is positioned substantially adjacent the bottom portion, and the other of the air inlet and the air outlet is positioned substantially adjacent the upper portion, the air inlet and the air outlet being substantially spaced from one another along the conduit by a middle portion free of air inlets and outlets; and

a fan coupled to the container and positioned such that the fan circulates air within the container through the conduit.

12. The food display of claim 11, further comprising a sign panel coupled to the container and being at least partially translucent;

and

a light assembly including a light source positioned to provide light to both the container and the sign panel.

13. The food display of claim 11, further comprising four corner posts that support the container, each of the four corner post is hollow and acts as a conduit.

14. The food display of claim 11, further comprising an upper assembly positioned above the container, the fan positioned in the upper assembly and the conduit in communication with the upper assembly.

15. The food display of claim 14, further comprising a heating element positioned in the upper assembly;

wherein the air inlet is positioned substantially adjacent the lower portion and the air outlet is positioned substantially adjacent the upper portion and in direct communication with the upper assembly; and

wherein the fan blows air past the heating element to supply heated air to the container.
