Abstract

A foldable tray with stable side walls and tapered walls for convenient stacking is provided. The tray may include two outward tapered walls and two straight walls. The side walls are reinforced or stabilized by providing an interlocking end flap tab inserted through a cut line in the side wall. The tray may also include a hinged lid to form a hinged box. The lid may include an inwardly tapering wall to accommodate and overlay one of the outwardly tapering walls of the tray.

First claim

What is claimed is:

1. A foldable tray comprising:
a bottom panel;
a plurality of wall panels foldably connected to said bottom panel and extending upward therefrom;
at least one end flap foldably connected to an end of a first wall panel of said plurality of wall panels;
at least one cut defined in an adjacent second wall panel of said plurality of walls panels; and
a fold flap formed by a fold line defined in said second wall panel;
wherein said end flap is secured to said fold flap.

2. The foldable tray of claim 1 , wherein said at least one end flap is configured for partial insertion into said cut defined into said adjacent second wall panel.

3. The foldable tray of claim 2 , wherein a distal end of said at least one end flap is configured to insert into said cut.

4. The foldable tray of claim 3 , wherein said distal end of said at least one end flap extends past the cut at a length no less than 5% of the shortest length from the fold line of said folding corner to a tip of said distal end of said at least one end flap.

5. The foldable tray of claim 2 , wherein said tray is configured for having a collapsed position where said plurality of wall panels are folded downward against said bottom panel in a flattened state and configured for having an upright position where said plurality of wall panels extend upwardly from said bottom panel and at least one wall panel has an angled orientation relative to said remaining plurality of wall panels to form a tapered profile.

6. The foldable tray of claim 1 , wherein said cut includes a continuous curved cut.

7. The foldable tray of claim 6 , further comprising an insert slit positioned radial to said continuous curved cut.

8. The foldable tray of claim 1 , wherein at least one wall panel of said plurality of wall panels includes a tapered profile.

9. The foldable tray of claim 8 , wherein said tray is configured for stacking with a second identical tray.

10. The foldable tray of claim 9 , wherein said tapered profile of said wall panel having a tapered profile allows said tray to nest with said second identical tray.

11. The foldable tray of claim 1 , wherein said bottom panel is a rectangle and said plurality of wall panels comprise two end panels and two side panels, and wherein said side panels are positioned parallel to one another.

12. The foldable tray of claim 11 , wherein each said end panel comprises two opposing said end flaps.

13. The foldable tray of claim 12 , wherein each of said end flaps is fixed to a triangular fold flap on each side panel.

14. The foldable tray of claim 13 , wherein each said side panel comprises at least one said cut proximal at least one respective said end flap.

15. The foldable tray of claim 11 , wherein at least one of said end panels forms said tapered profile, and wherein said tapered profile is an outward tapered profile.

16. The foldable tray of claim 1 further comprising:
a top panel foldably connected to one of said plurality of wall panels;
three top wall panels foldably connected to said top panel extending downward therefrom when said top panel is in a closed position; and
at least one end flap foldably connected to an end of one of said three top wall panels;
wherein at least one top wall panel of said three top wall panels includes a tapered profile.

17. The foldable tray of claim 16 , wherein said top panel is a rectangle and said three top wall panels comprise two side top wall panels and one end top wall panel, and wherein said top wall panels are positioned parallel to one another.

18. The foldable tray of claim 17 , wherein said end top wall panel comprises two end flaps.

19. The foldable tray of claim 18 , wherein each said end flap of said top wall panel is fixed to a triangular fold flap on each of side top wall panel.

20. The foldable tray of claim 19 , wherein said end top wall panel includes a tapered profile.

21. The foldable tray of claim 20 , wherein said tapered profile of said end top wall panel is an inward tapered profile.

22. A foldable unitary blank for formation into a tray, said blank comprising:
a bottom panel;
two side panels, each connected to said bottom panel by a side panel fold line;
two end panels, each connected to said bottom panel by an end panel fold line;
an end flap foldably connected to a side of one of said end panels;
a fold flap formed by a fold line defined in one of said side panels; and
a cut defined through one of said side panels positioned adjacent to said end flap;
wherein said cut is configured to receiving a lower corner of said end flap when said blank is folded into said tray; wherein said tray includes a tapered wall facilitated by said end flaps insertion through said cut and wherein said end flap is configured to be secured to said fold flap.

23. The foldable unitary blank of claim 22 , wherein said tapered wall of said tray tapers outwardly when the blank is formed into a tray.

24. The foldable unitary blank of claim 22 further comprising:
a top panel connected to one of said two end panels by a top panel fold line;
two additional side panels, each connected to said top panel by a side panel fold line;
one additional end panel connected to said top panel by an end panel fold line;
two end flaps foldably connected to each end of said additional end panel;
wherein each end flap foldably connected to a side of said additional end panel includes a tapered edge configured to frictionally meet the top panel when said blank is folded into a lid of said tray; wherein said lid includes a tapered wall facilitated by said tapered edge meeting the top panel.

25. The foldable unitary blank of claim 24 , wherein said tapered wall of said lid tapers inwardly.

26. A foldable tray comprising:
(a) a base tray including:
(i) a bottom panel, and
(ii) a plurality of bottom wall panels foldably connected to said bottom panel and extending upward therefrom, wherein at least one of said plurality of bottom wall panels tapers outwardly;
at least one end flap foldably connected to an end of a first wall panel of said plurality of bottom wall panels;
a fold flap formed by a fold line defined in a second wall panel of said plurality of wall panels; and
at least one cut defined in said second wall panel of said plurality of wall panels;
wherein said end flap is secured to said fold flap; and

(b) a lid including:
(i) a top panel foldably connected to one of said plurality of bottom wall panels (a)(ii); and
(ii) three top wall panels foldably connected to said top panel extending downward therefrom, wherein at least one of said plurality of top wall panels tapers inwardly, and

wherein said inwardly tapering top wall panel overlaps said outwardly tapering bottom wall when said lid is in a closed configuration.
