Display tray

1. A knockdown assembly configured to be assembled into a display tray having at least one corner column, the knockdown assembly comprising:

a lower blank comprising a lower blank central region having first, second, third, and fourth edges;

an upper blank comprising an upper central region having first, second, third, and fourth edges, and a column portion extending from a corner of the upper central region;

wherein said upper central region and said lower central region have substantially the same shape and size;

wherein a lower surface of said upper blank is adhesively attached to an upper surface of said lower blank so as to line up the upper central region on top of the lower central region; and

wherein said column portion includes at least three column walls, and wherein said column walls are foldable relative to one another such that said corner columns have a polygonal cross-section when said knockdown is assembled into said display tray.

2. The knockdown assembly according to claim 1 wherein the lower blank is substantially planar and the upper blank is substantially planar.

3. The knockdown assembly according to claim 1 wherein each of the upper and lower blanks is formed from a single, unitary sheet of corrugated paperboard.

4. The knockdown assembly according to claim 1 wherein said column portion includes a median edge integral with the upper blank central region and a lateral edge, wherein said column portion is folded upon itself and the lateral edge is secured proximate to the median edge.

5. The knockdown assembly according to claim 1 wherein said column portion includes at least four column walls.

6. The knockdown assembly according to claim 5 wherein two of said column walls are attached and substantially parallel to one another and another two of said column walls are attached and substantially parallel to one another, and wherein said two column walls are adjacent to and positioned in a face to face relationship with said another two of said column walls, and wherein said two column walls and said another two of said column walls move out of said face to face relationship when said knockdown assembly is assembled into the display tray.

7. The knockdown assembly according to claim 1 wherein said column portion defines a trapezium shaped cross-section when the knockdown is assembled into said display tray.

8. The knockdown assembly according to claim 1 wherein said corner column is configured to extend substantially perpendicular to the upper central region when said knockdown assembly is assembled into the display tray.

9. The knockdown assembly according to claim 1 wherein said first, second, third and fourth edges of said lower blank central region are surrounded at each edge by first, second, third and fourth sidewall segments, said first sidewall segment includes a rollover portion, and each of said second and fourth sidewall segments include at least one end flap extending therefrom and which form part of a first side wall with said rollover portion when said knockdown assembly is assembled into the display tray.

10. The knockdown assembly according to claim 9 wherein each of said at least one end flap of each of said second and fourth sidewall sections extend along the lower central region first edge with the first edge rollover portion folded over and retaining said end flaps in place when said knockdown assembly is assembled into the display tray.

11. The knockdown assembly according to claim 9 wherein at least one of said first, second, third and fourth sidewall segments defines a display opening cutout.

12. The knockdown assembly according to claim 1 wherein the lower central region includes at least one lower notch and the upper central region includes at least one upper notch, and wherein the lower notch and upper notch are aligned upon attachment of the upper and lower blanks.

13. A display tray formed from the knockdown assembly according to claim 1 .

14. A knockdown assembly configured to be assembled into a display tray, the knockdown assembly comprising:

a lower blank comprising a lower blank central region surrounded by first, second, third and fourth sidewall segments attached thereto;

an upper blank comprising an upper blank central region having first, second, third, and fourth column portions extending from first, second, third, and fourth corners of the upper blank central region;

said upper blank central region and said lower blank central region having substantially the same shape and are substantially equal in size; and

wherein a lower surface of the upper blank is adhesively attached to an upper surface of the lower blank so as to line up the upper central region on top of the lower central region.

15. The knockdown assembly according to claim 14 wherein at least one of said column portions includes a median edge integral with the upper blank central region and a lateral edge, wherein said at least one column portion is folded upon itself, and wherein the lateral edge is secured proximate to the median edge.

16. The knockdown assembly according to claim 14 wherein at least one of said column portions includes at least three column walls, wherein one of said column walls is adjacent to and in face to face relationship with one of said sidewall segments of said lower blank.

17. The knockdown assembly according to claim 16 wherein said column walls are foldable relative to one another to form a polygonal cross-section when said knockdown assembly is assembled into said display tray.

18. The knockdown assembly according to claim 14 wherein at least one of said column portions includes at least four column walls, two of said column walls are attached and substantially parallel to one another and another two of said column walls are attached and substantially parallel to one another, and wherein said two column walls are adjacent to and positioned in a face to face relationship with said another two of said column walls, and wherein said two column walls and said another two of said column walls move out of said face to face relationship when said knockdown assembly is assembled into the display tray.

19. A display tray formed from the knockdown assembly according to claim 14 .
