摘要：
A preform is biaxially stretch blow molded into a container by using a liquid as a pressurizing medium. The preform is formed in a bottomed tubular shape including a mouth, a trunk, and a bottom by extrusion blow molding. The preform includes bottom parting lines, which are formed in the bottom due to the extrusion blow molding, and the bottom parting lines are configured to extend to the outer side from the axis of the bottom to divide the bottom into at least three parts in the circumferential direction. Further, a container is formed by biaxially stretch blow molding the preform by using the liquid as the pressurizing medium.
