<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a pouch container which is excellent in self-supporting stability and shape retention, whose capacity can be reduced, in which liquid-tightness between a body member and the bottom can be sufficiently secured, and by which a bag-making work is easily automated, and an end folding back device to be used for the same.SOLUTION: A method for manufacturing a pouch container comprises: a body member setting process of internally packaging a body member 5A at a developed state in an internal cylinder 15 of a blocking jig 10, and inserting a plurality of pawl parts 32a into an upper end part 5Ab of the body member 5A at intervals in a circumferential direction; and a folding back process of moving the plurality of pawl parts 32a to a lower side so as to be externally fit into an upper end part of the internal cylinder 15 after or while spreading the upper end part 5Ab of the body member 5A to the outside by the plurality of pawl parts 32a, thus, folding back the upper end part 5Ab of the body member 5A to the outside so that the inside and the outside are inverted centering on the upper end part of the internal cylinder 15, and manufacturing a body member 5B having an endless annular folding back part 5Bb at the upper end.</p> |
