PROBLEM TO BE SOLVED: To provide a bag-in-box that causes no leakage of liquid from between a spout and an attachment by giving no damage to a liquid stop forming portion of a discharge tube of the spout due to a sink when forming the spout or the insertion and removal of a filling nozzle end, in the spout that is attached to a bag-in-box inner bag.SOLUTION: A spout includes: a filling nozzle receiving portion 12 provided in a range from a height position lower than an engaging ring 6 to an upper end position of a discharge tube 2 within the discharge tube 2; and a liquid stop forming portion 13 provided at a lower part of the filling nozzle receiving portion 12, and for making contact with a sealing ring 9 of an attachment device 7 to stop liquid. The inner diameter of the filling nozzle receiving portion 12 is made larger than that of the liquid stop forming portion 13, and the thickness of the upper part of the discharge tube where the engaging ring 6 is positioned, is reduced. |
