Abstract

A partition assembly (10) comprising a partition matrix made up of intersecting first and second slotted partitions (12, 14), each of the partitions having at least one slot (28, 30). The slots (28, 30) of the partitions (12, 14) are engaged with each other at a plurality of intersections. The partitions (12, 14) are made by folding over a partition blank (66) and securing a foam portion (38) of the folded partition blank (66) to itself. The foam (38) may be heated with hot air before being cooled under pressure to secure opposed plies (32, 34) of the partition together.

Claims (26)

1. A partition assembly comprising:

at least one first slotted partition, each first slotted partition having at least one slot extending inwardly from an edge thereof;

at least one second slotted partition, each second slotted partition having at least one slot extending inwardly from an edge thereof;

said first and second slotted partitions being arranged in a matrix, said at least one slot of said at least one first slotted partition being engaged with said at least one slot of said at least one second slotted partition at an intersection, at least one of said partitions having a rounded upper edge and being formed by folding over a partition blank and securing opposed plies of said partition blank together.
2. The partition assembly of claim 1 wherein said at least one of said partitions has a foam interior portion.
3. The partition assembly of claim 1 wherein said opposing plies are parent welded together.
4. The partition assembly of claim 1 wherein said at least one of said partitions is made of a multi-layered material.
5. The partition assembly of claim 2 wherein said foam interior portion is polyolefin foam.
6. A partition assembly comprising:

a plurality of first slotted partitions, each first slotted partition having a plurality of slots extending inwardly from an edge thereof;

a plurality of second slotted partitions, each second slotted partition having a plurality of slots extending inwardly from an edge thereof;

said first and second slotted partitions being arranged in a matrix, said slots of said first slotted partitions being engaged with said slots of said second slotted partitions at intersections, at least one of said partitions having a foam interior portion and an outer skin secured to said foam interior portion.
7. The partition assembly of claim 6 wherein said foam interior portion is two ply.
8. The partition assembly of claim 7 wherein said plies are secured together.
9. The partition assembly of claim 6 wherein said at least one of said partitions is formed by folding a partition blank and securing opposed plies of the partition blank together.
10. The partition assembly of claim 6 wherein said first and second partitions are made from the same material.
11. A partition assembly comprising:

at least one first slotted partition, each first slotted partition having at least one slot extending from one edge of the first slotted partition;

at least one second slotted partition, each second slotted partition having at least one slot extending from one edge of the second slotted partition;

each of said first and second slotted partitions comprising an outer face surrounding a foam interior and a smooth upper edge, said first and second slotted partitions being arranged in a matrix, a slot of a first slotted partition being engaged with a slot of a second slotted partition at an intersection.
12. The partition assembly of claim 11 wherein said outer face of each of said partitions comprises a woven polyester.
13. The partition assembly of claim 11 wherein said foam interior is polyolefin foam.
14. The partition assembly of claim 11 wherein each of said partitions is formed by folding a partition blank and securing the partition blank to itself.
15. The partition assembly of claim 11 wherein said outer face of each of said partitions comprises a plastic material.
16. A slotted partition for use in a partition assembly, said slotted partition comprising:

a first ply and a second ply formed by folding a partition blank to create a rounded edge, said first ply being parent welded to said second ply;

a plurality of slots extending inwardly from an edge thereof.
17. The partition of claim 16 wherein each of said plies comprises an interior foam portion and an exterior skin.
18. A slotted partition for use in a partition assembly, said slotted partition comprising:

an interior foam portion;

an exterior skin secured to the interior foam portion;

a plurality of slots extending inwardly from an edge thereof.
19. The partition of claim 18 wherein said interior foam portion of said partition is a polyolefin foam.
20. A method of forming a partition for use in an intersecting partition matrix, the method comprising the steps of:

providing a partition blank;

folding the partition blank so as to create two opposed plies;
parent welding the opposed plies together into a two ply partition.
21. The method of claim 20 further comprising slotting the two ply partition.
22. The method of claim 20 wherein parent welding the opposed plies comprises heating at least one of the plies and allowed the opposed plies to cool under pressure.
23. A method of forming a partition for use in a partition matrix, said method comprising the steps of:

providing a partition blank comprising an outer skin, a middle layer and a foam interior layer;

folding the partition blank to create two opposed plies;
heating said foam interior layer of at least one of the plies;

applying pressure to the opposed plies to join the foam interior layers while the foam interior layers cool; and slotting said partition.
24. The method of claim 23 wherein heating the foam interior layer of at least one of the plies comprises blowing hot air on the foam interior of at least one of the plies.
25. A method of forming a partition for use in a partition matrix, said method comprising the steps of:

providing a partition blank comprising an outer skin and a foam interior layer;

folding said partition blank so as to create two plies and a smooth upper edge, securing said foam interior layers of said plies together; and slotting said partition.
26. The method of claim 25 wherein securing said foam interior layers of the plies together comprising heating at least one of the foam interior layers and allowing the foam interior layers to cool under pressure.
