Claims

1. A packaging system, comprising

a bottom cap constructed from foldable corrugated material;

a top cap constructed from foldable corrugated material;

a plurality of trays wherein each tray is constructed from foldable corrugated material and comprises at least two outboard flaps and a center flap arranged in an end-to-end configuration such that outboard flaps each are foldable over the center flap, thereby defining a three-ply construction for use as a tray; and

at least one of a top sheet, bottom sheet, or both wherein the top sheet or bottom sheet or both are contained within the top cap or bottom cap or both, wherein

each flap includes a pattern of holes which are in patterned alignment when the outboard flaps are folded over the center flap and the holes of at least one flap are of a diameter which is less than a diameter of the holes on one of the outboard flaps so as to define an annular lip.

2. The packaging system according to claim 1, wherein the at least two outboard flaps and the center flap of at least one tray are foldably connected.

3. The packaging system according to claim 1, wherein the system contains at least one top sheet contained within the top cap and at least one bottom sheet contained within the bottom cap.

4. The packaging system according to claim 1, wherein the top cap, bottom cap, or both comprise a plurality of side walls formed from a plurality of side wall panels.

5. The packaging system according to claim 4, wherein the top cap, bottom cap, or both comprise at least four side walls.

6. The packaging system according to claim 1, wherein the top cap, bottom cap, or both comprise a center panel.

7. The packaging system according to claim 6, wherein the top cap, bottom cap, or both comprise a center panel having a plurality of center panel corners.

8. The packaging system according to claim 7, wherein at least one of the center panel corners has a curvilinear shape.

9. The packaging system according to claim 1, wherein the top cap, bottom cap, or both comprise

a plurality of side walls having opposite ends;

and

a center panel having a plurality of center panel corners, wherein

at least one of the center panel corners has a curvilinear shape; and

at least of the opposite ends of at least one of the side walls has a curvilinear shape.

10. The packaging system according to claim 9, wherein at least one of the center panel corners having a curvilinear shape and at least of the opposite ends of at least one of the side walls having a curvilinear shape are positioned adjacent to one another to define a curvilinear corner of the top cap, bottom cap, or both.

11. The packaging system according to claim 1, wherein the top cap, bottom cap, or both comprise a plurality of side walls having opposite ends, wherein a first opposite end contains a tab and a second opposite end contains a tab-receiving opening positioned such that the side walls are locked into an erected position by inserting the tab of a first side wall into the tab-receiving opening of an adjacent second side wall.

12. The packaging system according to claim 1, wherein the top cap, bottom cap, or both comprise a plurality of side walls, wherein a portion of a first side wall is affixed to a portion of a second side wall.

13. The packaging system according to claim 12, wherein a portion of a first side wall is affixed to a portion of a second side wall by at least one member selected from the group consisting of tape, adhesive, and staple.

14. The packaging system according to claim 1, wherein at least one tray comprises at least one of the outboard flaps foldably connected to the center flap along a thin bridge element such that the thin bridge element spaces an edge of the at least one outboard flap from an edge of the center flap.

15. The packaging system according to claim 1, wherein at least one tray comprises at least one of the outboard flaps foldably connected to the center flap along a fold line.

16. The packaging system according to claim 1, wherein at least one tray comprises at least two outboard flaps and a center flap arranged such that, when folded, a face of at least one second outboard flap is positioned between a face of the center flap and a face of at least one first outboard flap.

18. The packaging system according to claim 1, wherein at least one tray has at least one corner that is curvilinear.

19. The packaging system according to claim 1, wherein at least one flap contains at least one selected from the group of circular holes, non-circular holes, rounded holes, octagonal holes, octagonal holes with rounded corners, and octagonal holes with arched sides.

20. The packaging system according to claim 1, wherein the top sheet, bottom sheet, or both contain a pattern of holes.

17. The packaging system according to claim 17, wherein the at least one first outboard flap is foldably connected to the center panel by a thin bridge element such that, when folded, the at least one first outboard panel is spaced from the center panel.

21. The packaging system according to claim 21, wherein the pattern of holes of the top sheet, bottom sheet, or both matches the pattern of holes of a tray adjacent thereto.

22. The packaging system according to claim 21, wherein the top sheet, bottom sheet, or both contain at least one selected from the group of circular, non-circular, rounded, octagonal holes, octagonal holes with rounded corners, and octagonal holes with arched sides.
