PROBLEM TO BE SOLVED: To provide a manufacturing method of a synthetic substance container for liquid provided with a take off pipe joint and characterized by high manufacturing performance. SOLUTION: The container 2 consists of the blow-molding of a tubular preformed unwrought casting product, a retaining flange 19 and a threaded connecting pipe 20 are formed in the back section 21 in the arched section 12 of the bottom side which holds the take off pipe joint 10 in the front wall 3 of the container 2. The arched section 12 is cut off in order to form an opening section 11 for emptying a load inside the retaining flange 19 and the threaded connecting pipe 20. The housing 22 of the take off pipe joint has an inflow connecting pipe 23 and an outflow connecting pipe 24. The take off pipe joint 10 assembled and attached beforehand is that the inflow connecting pipe 23 is welded to the retaining flange 19 or the threaded connecting pipe 20 of the container 2 and this container 2 is aligned and retained within this welding machine by this retaining flange 19 or the threaded connecting pipe 20.
