PROBLEM TO BE SOLVED: To form a container mainly for a dangerous substance in a volume of 1,000 liters and a liquid in an intermediate size except a deleterious substance and a multi-purpose container as a structure which can be folded and assembled by an easy-to-operate task by one person to make transportation and distribution of the liquid efficient, by reducing a cost for collecting the container after unloading and allowing a returning truck to load cargoes. SOLUTION: A top plate 5 with a manhole of an outer vessel 2 having a flexible pressure membrane 16 such as rubber or a resin internally mounted is coupled with a frame-type bending side plate 7 and hung horizontally. Flat side plates 8 are alternately fallen inwardly and folded to form the container 1 which can be stacked on outer legs 14. In addition, a spring is mounted on a middle bending portion of the bending side plate 7 to constitute a barrel as a self-supporting type with its middle half standing. A center coupling and rotating mechanism 23 each comprising four surfaces of a barrel provided as an arm-type bending side plate 22 in diagonal directions and a bending pillar 25 are provided to be internally folding to form the container 1A. |
