A spout is inserted into the aperture, the spout and the second web of panel materialbeing heat sealed with each other. The second web of panel materialis guided by a guide deviceto be folded after being heat sealed so that a second folded portion should be formed in the second web of panel material. The spout is turned over by the second folded portion. The second folded portion and the first folded portion are heat sealed with each other while the second folded portion and the second web of panel materialare heat sealed with each other about the spout.
