Title: Arrangement for the stacking in a space-saving manner of tetrahedral packing units in a prismatic collective container

Abstract: An arrangement for stacking tetrahedral packing units in layers in a space-saving manner in a prismatic collective container from the bottom up in which the bottom wall of the container is provided with an array of openings through which a corresponding array of supporting members are inserted and engage respectively with an inclined wall of each of six regular tetrahedral packing units which form the bottommost layer. When the bottom layer has been so loaded into the container three additional six-unit layers are loaded in succession into the container after which the supports can then be withdrawn and the four layers so loaded into the container will be automatically retained in the position in which they have been stacked.
