POUCH AND METHOD OF PRODUCING POUCH CONTAINER WITH SPOUT

摘要

A pouch and a production method for a spout pouch container are provided, which suppress curling of an opened spout attachment edge portion and offset of a filling port defining edge portion adjacent to the spout attachment edge portion when a spout is heat-sealed to the spout attachment edge portion. The pouch (10) is of a bottom gusset type, which includes a pair of front and rear exterior sheets (11, 12) and a gusset sheet (13) folded inward from lower portions of the exterior sheets (11, 12) to define a bottom gusset portion. When a spout (20) is attached to the pouch (10), a spout attachment edge portion (10A) and a filling port defining edge portion (10B) disposed adjacent the spout attachment edge portion (10A) and defining a filling port through which a liquid product is filled as content in the pouch are unsealed, but a spot-seal portion (PS) formed by partly heat-sealing the pouch is disposed in a region around a boundary between the spout attachment edge portion (10A) and the filling port defining edge portion (10B).
