摘要:
A pressure wide-mouth container made of synthetic resin and having a cylindrical body portion, a flange portion projecting from the periphery of a wide mouth formed at one end of the body portion; and a bottom portion closing the other end of the body portion. The flange portion and a peripheral portion of the wide mouth are formed by injection molding and not drawn after the injection molding is carried out. The body portion except the peripheral portion of the wide mouth and the bottom portion are formed by the injection molding and drawn by a blow molding to be performed after the injection molding is carried out and the bottom portion is drawn at a lower drawing ratio than the body portion.
