The invention claimed is: 1. A device for releasing and locking collapsible side walls of a container, said device comprising: an actuator in combination with collapsible side walls that can be folded down onto a container bottom, wherein at least one side wall of said side walls can be releasably
The invention claimed is: 1. A device for releasing and locking collapsible side walls of a container, said device comprising: an actuator in combination with collapsible side walls that can be folded down onto a container bottom, wherein at least one side wall of said side walls can be releasably interlocked with two opposite side walls of the other side walls, said one side wall having an outer face and a handling opening extending therethrough, and said handling opening having a lower edge; and said actuator comprising an elongate member with a medial portion defining a grip member and with end portions defining a pair of locking lugs, said elongate member including a downward bulge with respect to said portions, said actuator being arranged on said outer face of said one side wall, said grip member located at or below said lower edge of said handle opening, said locking lugs engaging said opposite side walls when in an interlocked position to thereby lock said one side wall to said two opposite side walls, an upward lifting movement of said grip member displacing said locking lugs in an upward direction in such a manner that said one side wall becomes released from said two opposite side walls and can be folded inwards. 2. A device in accordance with claim 1, wherein said actuator is elastically pre-tensioned into the interlocked position. 3. A device in accordance with claim 1, further comprising a second side wall, a second actuator being provided on said second side wall for releasably engaging said two opposite side walls to interlock said second side wall with said two opposite side walls. 4. A device in accordance with claim 1, wherein said locking lugs are formed at free ends of said elongate member. 5. A device in accordance with claim 1, wherein said actuator extends over the length of said one side wall. 6. A device in accordance with claim 5, wherein said locking lugs are formed at free ends of said elongate member. 7. A device in accordance with claim 1, wherein said elongate member is arranged on an outer face of the said one side wall. 8. A device in accordance with claim 1, wherein said grip member is arranged in a central region or said elongate member. 9. A device in accordance with claim 1, wherein said grip member is below said lower edge of the handling opening at least when in said interlocked position. 10. A device in accordance with claim 1, wherein said actuator is elastically pre-tensioned in said interlocked position by two pre-tensioning devices. 11. A device in accordance with claim 10, wherein said pre-tensioning devices comprise arc-shaped spring clips that bear against a part of said one side wall. 12. A device in accordance with claim 1, wherein said one side wall includes vertical stiffener ribs on an outer face of said one side wall, at least one rib of said ribs having a recess, said actuator held in said recess of said at least one rib. 13. A device in accordance with claim 1, wherein said grip member includes a wavy portion defining hollows for fingers. 14. A device in accordance with claim 1, wherein said elongate member comprises a unitary member. 15. A device in accordance with claim 1, wherein said elongate member is bar-shaped. 16. A device in accordance with claim 1, wherein each of said two opposite side walls includes a hook, said locking lugs engaging said hooks to thereby interlock with said two opposite side walls. 17. A device in accordance with claim 4, wherein said actuator extends over the length of said one side wall. 18. A device in accordance with claim 1, wherein said one side wall is shorter than said two opposite side walls. 19. A device in accordance with claim 10, wherein said one side wall includes an outer face, said actuator mounted to said outer race. 20. A device in accordance with claim 19, wherein said outer face side includes ribs. 21. A device in accordance with claim 20, wherein said pre-tensioning devices comprise spring-like clips, said clips bearing against said ribs to thereby pre-tension said actuator in said interlocked position. 22. A device in accordance with claim 20, wherein said actuator is supported by said ribs. 23. A device in accordance with claim 22, wherein a portion of said actuator supported in said ribs is closer to an upper rim of said one side wall than said grip member. 24. A device in accordance with claim 22, wherein each of said ribs supporting said actuator includes a recess, said actuator being supported in said recesses. 25. A device in accordance with claim 22, wherein each of said two opposite side walls has a hook, said locking lugs engaging said hooks when in said interlocked position. 26. A device in accordance with claim 25, wherein said pre-tension devices comprise spring-like clips. 27. A device in accordance with claim 26, wherein said spring-like clips bear against a part of said one side wall. 28. A device in accordance with claim 27, wherein said spring-like clips bear against ribs of said one side wall. 29. A device in accordance with claim 28, wherein said spring-like clips bear against ribs of said one side wall provided on opposed sides of said handling opening. 30. A device in accordance with claim 29, wherein said ribs on opposed sides of said handling opening are located above said lower edge of said handling opening.
