Abstract

A bin formed with a general circular shape in plan being formed from an outside liner of paperboard and an inner paperboard flute providing medium which is affixed to the outside liner. The flutes of the flute providing medium are larger than those of "A" flute. A removable sleeve interior, an optional base and lid are provided together with methods of carriage using same.

1. A bin of substantially circular form when viewed in plan, said bin comprising:

an assembly of at least one single-face corrugated structure having flutes running vertically and exposed to an inside of the bin when in an erected form,

said at least one single-face corrugated structure including a liner board of at least one ply of kraft paper adhesively laminated to a corrugated laminate of at least two plies, with at least one of said at least two plies including a ply of kraft paper, said corrugated laminate being set in the corrugated form by moisture, heat and pressure,

said flutes of the at least one single-face corrugated structure being at least grater than "A" flute size, and

a support surface for supporting said at least one single-face corrugated structure.

2. A bin as claimed in claim 1, wherein said at least two plies are each a laminate including at least one ply of kraft paper and the corrugated form and the lamination between said at least two plies being achieved by the at least two plies being laminated together in corrugated form, using an adhesive, by moisture, heat and pressure.

3. A bin as claimed in claim 1, wherein said assembly is of substantially circular shape.

4. A bin as claimed in claim 1, wherein said at least one single face corrugated structure is lapped at at least one point by at least one flute width.

5. A bin as claimed in claim 4, wherein said at least one single-face corrugated structure is lapped at two points by at least one flute width.

6. A bin as claimed in any one of claim 1, wherein said at least one single-face corrugated structure is a laminate of 160 gram/m² kraft paper liner and a layer of 530 gram/m² box board.

7. A bin as claimed in claim 6, wherein the corrugated laminate is formed using EVA adhesive.

8. A bin as claimed in any one of claim 1, wherein said at least one single face corrugated structure has a flute pitch of about 54 mm, flute depth of about 27 mm and a take up of about 1.5:

1.

9. A bin as claimed in claim 1, wherein said bin is bottomless.

10. A bin as claimed in claim 1, wherein said assembly is encircled by at least one strengthening band.

11. A bin as claimed in claim 10, wherein said assembly is encircled at least at a top and a bottom by said at least one strengthening band.

12. A bin as claimed in claim 10, wherein said encircling band is of a fibreboard construction.

13. A bin as claimed in claim 1, wherein said support surface is supported by a pallet.

14. A bin as claimed in claim 1, wherein said assembly is collapsible to a substantially lie-flat form with the flutes being intermeshed.

15. A bin as claimed in claim 14, wherein said assembly includes hinges along two vertical pairs of fold lines, each fold line providing an edge in said lie-flat form.

16. A bin as claimed in claim 15, wherein said assembly is fabricated from two parts one of which carries both of said pairs of fold lines.

17. A bin as claimed in claim 1, wherein said assembly includes flaps engageable with a disc of a sheet material.

18. A bin as claimed in claim 1, wherein said assembly includes a volume greater than 500 liters, a height grater than 600 mm, and a capability of supporting at least 6 tons in a stacking mode.

19. A bin as claimed in claim 1, further comprising a liner material positioned internally of the assembly to lie against the assembly.

20. A bin as claimed in claim 19, wherein said liner is a sleeve capable of assuming a lie flat mode.

21. A bin as claimed in claim 19, wherein said liner is formed from one of fibreboard and kraft paper.

22. A bin as claimed in claim 19, wherein said liner is formed from laminated kraft paper.

23. A bin as claimed in claim 1, further comprising a plastics bag fillable to conform to the inside of said bin.

24. A bin as claimed in claim 1, further comprising a capping member including a lid region and a skirt or flange region to cap an upper region of the bin.

25. A method of transporting goods comprising:

erecting a bin on a support surface, said bin having an assembly of at least one single-face corrugated structure having flutes running vertically and exposed to an inside of the bin when in an erected form, said at least one single-face corrugated structure including a liner board of at least one ply of kraft paper adhesively laminated to a corrugated laminate of at least two plies, with at least one of said at least two plies including a ply of kraft paper, said corrugated laminate being set in the corrugated form by moisture, heat and pressure, said flutes of the at least one single-face corrugated structure being at least grater than "A" flute size, and a support surface for supporting said at least one single-face corrugated structure,

confining the goods to be transported within the bounds of the bin while the bin is supported on said support surface, and

retaining the goods within the bin.

26. A lay flat form capable of erection into a bin of a substantially circular form when viewed in plan, said lay flat form comprising:

an assembly of at least one single-face corrugated structure including a liner board of at least one ply of kraft paper adhesively laminated to a corrugated laminate of at least two plies, with at least one of said at least two plies including a ply of kraft paper, said corrugated laminate being set in the corrugated form by moisture, heat and pressure,

said flutes of the at lest one single-face corrugated structure being at least greater than "A" flute size,

wherein said corrugated structure has a flute pitch of about 54 mm, flute depth about 27 mm and a take up of about 1.5;

1.

27. A lay flat form as claimed in claim 26, wherein said at least one single-face corrugated structure is a laminate of 160 gram/m² kraft paper liner and a layer of 530 gram/m² box board.

28. A lay flat form as claimed in claim 27, wherein said laminate is formed using EVA adhesive.
