ABSTRACT:
In a flexible container, there is provided three or more approximately rectangular main sheets, and a rectangular inlet sheet and outlet sheet are provided on an imaginary line passing through approximately the central part in the width direction of each of the main sheets. One end of each of the inlet sheet and the outlet sheet in the direction along the imaginary line is sewed to an end of the main street corresponding to the one end, and the other end of each of the inlet sheet and the outlet sheet is projected away from the main sheet in the direction along the imaginary line. The imaginary lines of assembly sheets each constituted by the three types of sheets conform to one another, opposed surfaces of the adjacent assembly sheets are joined to each other, and outer side edges of the adjacent assembly sheets are sewed together.
