PURPOSE:To enable to obtain a uniform wall thickness, by shaping the parison contained connectedly in the first and second molds into a container part and a filler tube part by a blow molding, claming the second mold and shaping the filler tube part of a fixed size. CONSTITUTION:A parison is contained connectedly in the first mold 10 of a blow mold 9 and the second mold 11 where mold parts 14a, 14b are in the state of being retreated and it is blow molded, then the container part 7 of a fixed size and a filler tube part larger than the fixed size are obtained each with a nearly uniform wall thickness respectively from the first mold 10 and the second mold 11. The parts 14a, 14b of the second mold 11 are slided right after that, contacted at the mold parting faces 13a, 13b and the mold of the filler tube part is clamped, two semicircular parts of a resin in a groove 15 are fusion bonded integrally and the filler tube part 8 is shaped, the wall thickness being maintained. At the same time the residual part except both parts 7, 8 is removed. |
