摘要

PURPOSE:To provide a pressure-resistant self-standing plastic container with legs provided at the bottom of a petaloid form reinforced. CONSTITUTION:A pressure-resistant self-standing container 1 formed with a plurality of legs 12 forming a grounding part with equal intervals in a peripheral direction and having a recess 11 at the center of the bottom includes recessed ribs 14, 15 respectively formed at a radial inner part of each leg 12 and a radial inner part of a valley between the legs. The center recess 11 is formed by raising a protruding member at the time of biaxial orientation blow-molding to stretch the bottom center to 1.5 times or longer.
