ZIPPER POUCH WITH A SPOUT

摘要

Intended is to provide a pouch, which is constituted of a plurality of plastic sheets sealed at their peripheral edges, which includes a contents spout and a plastic zipper fused and arranged between the sheets at the sealed peripheral edges and which is heated and sterilized after it was charged with contents. The constitution of the pouch is characterized in that a blocking portion is formed by folding back a film-shaped base material at a portion in the pouch apart from the plastic zipper to the contents side, thereby to prevent such a drawback in advance that the contents might otherwise be caused by the influences of the heat or pressure to leave the blocking portion to the zipper portion, even if the blocking portion is wound during the plastic zipper manufacturing step or the step of mounting the zipper on the pouch, even for a retort sterilization or a heating or boiling sterilization after the pouch was filled with food or the like. Thus, it is possible to provide customers with the products stabilized in the quality management or the sanitary aspect.
