PROBLEM TO BE SOLVED: To provide a plastic bottle in which a holding part can be easily held, the holding part is not conspicuous outside, strength in the vertical direction is improved.SOLUTION: A plastic bottle 10 includes a mouth 11, a shoulder 12, a barrel part 20 and a bottom 30. The barrel part 20 has four side faces 21 and barrel part interfaces 22 positioned between the side faces 21, and provided with a horizontal concave rib 24 composed of side face horizontal concave ribs 24a arranged in each side face 21 and interface horizontal concave ribs 24b arranged in each barrel part interface 22. The shoulder 12 has a dome-like shape curved so that an outer edge of a cross section including the bottle axial direction protrudes outside, a plurality of pressure absorbing panels 23 are arranged side by side in the vertical direction in an upper region 21a and a lower region 21b of each side face 21. Pressure absorbing panels 23a and 23b in the vicinity of the side face horizontal concave rib 24a function as a holding panel. |
