Containers 10 have a base 12 and four side walls 14 which may fold to a stowed or collapsed position. Hinges connect each wall 14 to an intermediate member 16 which is clipped (preferably removably) to the base 12. Various interlocking formations 34, 36, 38, 40 allow containers to stack securely whether collapsed or erect.
