Zusammenfassung:	PURPOSE: A container forming method is provided to omit post-processing of a scrap protrusion by preventing the scrap protrusion in the bottom of a container from being generated in forming the container. CONSTITUTION: A parison(3) extrusion-molded in a parison forming die is sealed with cutting and jointing partially, and inserted to the bottom of an opened container mold(23). The container molds are combined, and the parison is separated from the parison forming die. A blow pin(29) is moved down into an injection port in the end of the parison, and the lower part of the parison is placed in the bottom of the container mold. The parison is blow-molded in the container mold with injecting air into the parison, and a container is formed. The formed container is output with dividing the container mold. The scrap is prevented from being generated in the bottom of the formed container by blow molding.
