1,078,484. Collapsible boxes. W. ZARGES. March 26, 1965 [April 3, 1964], No. 12997/65. Heading B8P. A collapsible container has two pairs of side walls 2, 3 and 4, 5 pivoted to the bottom 1, one pair 4, 5 being collapsible before the other pair 2, 3. Helical springs 6 are mounted between the walls 4, 5 and the bottom to automatically erect these walls after the walls 2, 3 are erected. The walls 2, 3 collapse inwardly under their own weight after the walls 4, 5 have been collapsed. Projections 7 on the walls 2, 3 or on the inside of the rim 11 serve to displace the walls 2, 3 inwards. Springs similar to those on the walls 4, 5 may be provided to urge the walls 2, 3 inwards. The walls each have hookshaped lateral edges (8), (9), Fig. 2 (not shown), which interengage and prevent the walls falling outwards. It is also possible to provide other means to prevent the walls falling outwards, for example, triangular plates (10), Fig. 3 (not shown), hinged centrally (12) or pieces of triangular shaped cloth connecting the bottom and one of the walls 2, 3. The upper edges of the side walls are preferably rounded 21, 31, 41, 51 and the open ends closed with plastics plugs. The container may be closed by a lid pivoted to one of the side walls.
