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 ( 10 A) and a filling port defining edge portion ( 10 B) disposed adjacent the spout attachment edge portion ( 10 A) 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 ( 10 A) and the filling port defining edge portion ( 10 B).
