ABSTRACT:
A branch type standing pouch which includes a pouch front side member including a pouring-out nozzle backside portion which constitutes a backside of a pouring-out nozzle by being folded back and a pouch body front side portion continuous therewith; a pouch backside member constituting a backside of the pouch body; a pouring-out nozzle front side member; and a bottom member. The pouch front side member, the pouch backside member, the pouring-out nozzle front side member, and the bottom member are respectively formed of plastic film and heat-sealed to each other so that a pouring-out nozzle is formed in a branched manner from a top of a pouch body. In this pouch, two symmetrical nozzle reinforcing areas are formed on both sides of a first protrusion as a result of a provision of the first to fourth protrusions. As a result, the branch type standing pouch in which the pouring-out nozzle can be fixed upright at a time of opening is obtained.
