A method of manufacturing a pouch container, includes: forming a pouch bag having one open end, by fusion-bonding a resin layer on an inner side of an end of a first film, with a resin layer on an inner side of an end of one or more second films; molding a mouth part member made of a resin, including a brim portion and a standing portion; attaching a lower surface of the brim portion of the mouth part member made of the resin to an outer resin layer of the first film of the pouch bag, by integrating the resins, using one of ultrasonic, heat, or high-frequency welding; filling the pouch bag with contents from the one open end of the pouch bag; and sealing an inside by fusion-bonding the one open end of the pouch bag to seal the pouch bag.

A dispenser pump has a plunger operable in a body including an outer cylinder body having a vent opening in its sidewall and a body insert fitting into the top of the body cylinder and providing an external collar through which the plunger stem operates. The body insert has a lock-down thread to lock down the plunger for shipping. The insert also has an undulating annular vent-control bead extending right round its cylindrical outer surface, engaging the cylinder wall with interference for either blocking or unblocking the vent opening, according to whether the vent-control bead lies above or below the interior vent opening, by rotation between the body cylinder and body insert. The rotation can be driven by rotation of the plunger head, which makes a catch engagement with the top of the body insert. Blocking the vent during shipping reduces leakage.
