The side walls and bottom are made up of regions interconnected by fold lines 15 and 16, enabling the container to be folded flat and then folded on itself to provide a compact article. The side walls may be attached to the end walls by flaps 17 provided with press studs 18. Handles 22 and 23 for carrying the erect container may be provided in the side and end walls, and a handle 20 for carrying the collapsed container may be attached to the bottom by portions 21 of the handle engaged in slots in the bottom.
