PROBLEM TO BE SOLVED: To stack a small-sized folding container on a large-sized folding container in a stable state by preventing the small-sized folding container which is placed on the large-sized folding container from detaching from long side walls of the large-sized folding container and being inclined, or from falling into inside of the large-sized folding container. SOLUTION: Fitting projections 2n which can be fitted in recesses 10c formed on the back face of a bottom part 10 of an upper positioned small-sized folding container C10 are formed on the upper face of a flange part 2e of long side walls 2 of a lower positioned large-sized folding container C1. When the small- sized folding container is stacked on the lower positioned large-sized folding container, the fitting projections which are formed on the upper face of the flange part of the long side walls of the lower positioned large-sized folding container are fitted in the recesses which are formed on the back face of the bottom part of the upper positioned small-sized folding container. |
