Abstract: In a combined module of a folding container, long-side bank portions 1a of a bottom 1 of a large folding container Cb are configured to be higher than short-side bank portions 1b of the bottom 1. Since the long-side bank portions of the bottom of the large folding container are configured to be higher than the short-side bank portions of the bottom 1, it is possible to improve the strength and rigidity of the bottom of the large folding container. Therefore, the large folding container can be prevented from being deformed or damaged by a load or twist.
