Wide-mouth container made of synthetic resin and method of manufacturing pressure wide-mouth container

A wide mouth container made of synthetic resinous material, which comprising,

• a body portion,
• a bottom portion closing at one end of the body portion,
• a wide mouth opening of other end of the body portion,
• a flange portion projecting from a periphery of a wide mouth,
• wherein the flange portion and the periphery of the wide mouth are formed by injection molding but not drawn after said injection molding, and the bottom portion and the body portion except the peripheral portion of the wide mouth are formed by the injection molding and then drawn by blow molding after injection molding, the bottom portion being dawn at a lower drawing ratio than the body portion,
• a thickness of the periphery portion of the wide mouth is larger than that of the flange portion, the thickness of the flange portion is larger than that of the body portion and the wide mouth is sealed by a lid.
