walls 12 and 14 first and second short side walls 16 and 18 and a dismantable or removeable bottom wall 20 the side walls are hinged to each other in a conventional manner so that when the bottom wall 20 is removed the four side walls may be folded together into a flat elongated package as illustrated in fig1 a and 15b the bottom wall 20 is supported all along its edges by a plurality of cantilever supporting elements 21 the invention is directed toward the construction of the support elements 21 since as will be explained in more detail below these support elements 21 are essential in effectively achieving the goals of the invention namely to assure sufficient mechanical strength for supporting a loaded bottom wall of the foldable crate to allow the hybrid stacking of foldable as well as solid crates and to allow such stacking in either overlapping or in the bonded brick stacking fashion see fig1 and to enable the basic design of the elements to be easily extended or changed into different shapes and configurations at minimum cost referring now to fig2 to 6 it will be seen that the side walls are essentially of the same design namely a u shaped top portion comprising flat top rim 22 web 23 and rib 24 a main wall portion 26 which may carry a lattice work pattern for the purpose of saving on material and weight of the crate as a whole and a lower substantially u shaped bottom portion comprising leg 28 web 30 bottom leg 32 and a plurality of stacking support elements denoted by the letter s the stacking support elements are.
