Collapsible containers configurable to provide a plurality of seaparate compartments are described, each having a back wall (84) carrying elements (104B, 104C) hingeably movable from positions parallel to the back wall to positions extending normally of that wall and defining compartments. In one embodiment stackable rigid structures (formed from inter-engageable boarding pieces) are placed within the container with the movable elements located between pairs of structures. In another embodiment the movable elements are rigid and form (when extended) bases for trays and lie immediately beneath side supports hinged to the back wall and rotatable from positions parallel to that wall to positions extending normally of that wall to act as end (and possibly) divider walls for the trays. A front wall (110) for each tray may be provided by a web carried between free edges of the side supports or by a rigid front wall part hinged to the free edge of the movable element and rotatable from a position parallel to that element to position extending normally thereof. The container may be of a foldable fabric, the movable parts being pockets carrying rigid planar pieces stitched to the back wall and resting when extended against parts of the frame. When not in use the fabric part may be folded and the frame collapsed for storage or transportation. The container may also be implemented in plates of metal or other rigid material with hinges between the movable parts.
