CLAIMS:

1. A container having a base and side walls extending from sides of the base, wherein at least some of the side walls are movable relative to the base to enable the container to be folded, and wherein at least some of the side walls are moulded separately from the base.

2. A container according to Claim 1 wherein all the side walls are movable relative to the base.

3. A container according to Claim 1 or claim 2 wherein all the side walls are each moulded in one piece separately from the base.

4. A container according to Claim 1, Claim 2 or Claim 3 wherein the side walls moulded separately from the base are engageable with the base so as to form a substantially rigid connection between part of the side walls and the base.

5. A container according to any one of the preceding claims wherein the side walls are movable relative to the base by virtue of hinges which are provided on or which are integral with the base.

6. A container according to any one of the preceding claims wherein the side walls are movable relative to the base by virtue of hinges which are provided on or which are integral with the side walls.

7. A container according to any one of the preceding claims wherein the base has first engaging means along some at least of the sides of the base, and some at least of the associated side walls have a fixing portion provided with second engaging means, the first and second engaging means being capable of engagement to secure the side walls to the base, there being provided a side wall portion hinged to each fixing portion.

8. A container according to Claim 7 wherein the first and second engaging means enable the fixing portions and base to be substantially rigidly secured together.

9. A container according to Claim 7 or Claim 8 wherein the base has first engaging means along all sides of the base.

10. A container according to Claim 7, Claim 8 or Claim 9 wherein all the side walls have a fixing portion provided with second engaging means.

11. A container according to any one of Claims 7 to 10 wherein the second engaging means of the side walls are engageable with receiving apertures of the base.

12. A container according to Claim 11 wherein the engagement includes a snap fitting engagement.

13. A container according to Claim 12 wherein the second engaging means comprise engaging formations adapted to be insertable into the receiving apertures of the base by causing resilient deformation of material surrounding the receiving apertures.

14. A container according to Claim 13 wherein the engaging formations are adapted to be insertable into the receiving apertures of the base by undergoing resilient deformation themselves.

15. A container according to Claim 12 or Claim 13 wherein the engaging formations comprise tongues or like protrusions which may generally only pass through the receiving apertures in one direction.

16. A container according to Claim 15 wherein the tongues or like protrusions become retained in position once such insertion is complete.

17. A container according to any one of Claims 12 to 16 wherein the tongues or like protrusions adapted for snap fitting engagement comprise a rearwardly facing surface providing an abutment surface which when the tongue or like protrusion is inserted into the receiving aperture of the base abuts part of the material surrounding the receiving aperture of the base.

18. A container according to Claim 17 wherein the tongues or like protrusions are provided with such an abutment surface on each side of the tongues or like protrusions.

19. A container according to Claim 18 wherein the tongues or like protrusions are of generally barbed bayonet type configuration.

20. A container according to any one of Claims 12 to 19 wherein not all of the tongues or like protrusions are adapted for snap fitting engagement.

21. A container according to Claim 20 wherein those tongues or like protrusions not adapted for snap fitting engagement comprise a tapered end part to facilitate location within receiving apertures of the base.

22. A container according to any one of the preceding claims wherein the base of the container is rectangular in plan view.

23. A container according to Claim 22 wherein the fixing portions of a first pair of opposite side walls are mounted at a higher level relative to the base than those of a second pair of opposite side walls.

24. A container according to Claim 23 wherein the side walls of the first pair are longer than those of the second pair.

25. A container according to any one of the preceding claims wherein each side wall portion is hinged to a respective fixing portion by a film of plastics material.

26. A container according to Claim 25 wherein the hinge is a "live" hinge.

27. A container according to Claim 24, Claim 25 or Claim 26 wherein side wall portions of the longer side walls have upper parts designed to permit one side wall portion of a longer side wall to partially overlie the other when the longer side walls are in an inwardly folded position.

28. A container according to Claim 27 wherein when the side wall portions of the longer side walls partially overlie each other, a generally planar outwardly facing surface is presented.

29. A container according to Claim 27 or Claim 28 wherein the upper parts are asymmetrical with respect to each other.

30. A container according to Claim 29 wherein the upper parts are tapered, the upper parts tapering generally towards the base of the container when the side walls are in a generally upstanding position.

31. A container according to any one of Claims 23 to 30 wherein ends of the longer side walls are provided with attachment formations adapted for engagement with corresponding parts on the other side walls.

32. A container according to Claim 31 wherein the attachment formations comprise clips or hooks.

33. A container according to any one of Claims 23 to 32 wherein the longer side walls are provided at their ends with inturned formations, the inturned formations being inturned towards the interior of the container.

34. A container according to Claim 33 wherein the attachment formations are provided on the inturned formations.

35. A container according to Claim 34 wherein the inturned formations lie generally in the same plane as an adjacent end wall when the side walls are in a generally upstanding position.

36. A container according to any one of Claims 31 to 35 wherein the attachment formations comprise clips and the corresponding parts on the adjacent end walls comprise apertures or recesses.

37. A container according to Claim 36 wherein the clip is adapted to resiliently deform part of the end wall adjacent or surrounding the recess or aperture.

38. A container according to Claim 36 or Claim 37 wherein the engagement between the attachment formations and the apertures is such that by relative generally vertical displacement of the longer side wall and adjacent end wall, the engagement may be released.

39. A container according to Claim 38 wherein the relative displacement comprises relative upward movement of the longer side wall and relative downward movement of the adjacent end wall.

40. A container according to Claim 39 wherein there is provided a section of reduced strength generally below a corner defined by a longer side wall and adjacent end wall.

41. A container according to any one of the preceding claims wherein the hinge associated with each side wall does not extend fully to corners of the container.

42. A container according to Claim 41 wherein the hinges terminate approximately 30mm from each corner.

43. A container having a base and side walls extending from sides of the base, wherein at least some of the side walls are movable relative to the base to enable the container to be folded, and wherein at least one pair of opposite side walls partially overlie each other when the container is in a folded condition, and wherein the pair of opposite side walls are so formed to reduce the height of the container in its folded condition.

44. A container according to Claim 43 wherein only those parts of the side walls which overlap with each other are so formed.

45. A container substantially as hereinbefore described.

46. A container substantially as shown in the accompanying drawings.
