Synthetic resin bottle

A synthetic resin bottle for aseptic filling, comprising a cylindrical body section, wherein

• the synthetic resin bottle has four pressure reduction absorbing panels configured to absorb pressure reduction after the bottle for aseptic filling is filled with a liquid at normal temperature and the bottle is sealed, which are arranged at equal intervals in the body section, and column portions each having an arc-shaped wall surface arranged between the pressure reduction absorbing panels,
• the arc-shaped wall surface of the column portion in a cross section of the body section constitutes a part of a virtual single true circle,
• an angle formed between a radial line passing through a circumferential center of the column portion and a radial line passing through a circumferential edge of the column portion is 55% to 75% of an angle formed between a radial line passing through a circumferential center of the column portion and a radial line passing through a circumferential center of a pressure reduction absorbing panel adjacent to the column portion at a position where the width in the circumferential direction of the pressure reduction absorbing panel is maximum,
• the body section has a cylindrical shape which corresponds to a perfect circle when the label is attached to the body section,
• wherein the synthetic resin bottle is an aseptic bottle which has a maximum amount of pressure reduction absorption of 10 ml or less for an internal capacity of 400 ml, and the synthetic resin bottle is structured to be used for aseptic filling only.
