ABSTRACT:
A spout assembly for a packaging bag for improving the prevention of oxidation to an inner content and discharging such content at a desired amount. The spout assembly mounted to the bag body includes a spool to move along the axial direction of the spout assembly and an urging member having an outer peripheral surface fixed to the inner peripheral surface of the spout assembly and adapted to urge the spool toward the bag body side. A check valve allows the inner content to flow only from the bag body side toward the mouth portion side. The urging member has a seat surface for the spool and the urging member presses the spool against the seat surface to shut off the flow of the inner content, and when an inner pressure of the bag body or a suction force of the mouth reaches a predetermined value, the spool separates from the seat surface.
