<p>PURPOSE:To accurately and reliably connect together a recetacle body a projecting body having a required thickness, size, and shape, by a method wherein, after a receptacle body and the projecting body are separately molded, the two parts are connected together by a heat plate welding or a hot blast welding. CONSTITUTION:A compressed air is blown into a parison 11 through a blow nozzle 14, and the parison 11 is expanded by blow into a shape in conformity with configuration of a cavity 12. A wall 2b, positioned corresponding to an opening part 7a in an implanting part 7, of a tank body 2 is removed by cutting to form an opening part 2a. An electric heating body 15, made of a brass plate, is inserted between the tank body 2 and the implanting part 7, a connection surface 8a, positioned on the outer surface of the wall of the tank body 2, and a connection surface 8b, positioned on an end surface of a flange 9 for the implanting part 7, are heated with the electric heating body 15 energized for heating, and after said part is brought into a molten state, the electric heating body 15 is removed to connect together by press the connection surfaces 8a and 8b between tank body 2 and the implanting part 7.</p> |
