To achieve a plastic bottle that has a decomposition absorption function and high strength at the same time.SOLUTION: In a plastic bottle comprising a decomposition absorption panel 33 and a barrel reference surface 34 on a barrel part, the decomposition absorption panel 33 is provided in a shape that extends in the vertical direction of the barrel part and is twisted in the circumferential direction around the central axis of the bottle, a first concave part 33a caves from the barrel reference surface 34 toward the inside of the bottle, a second concave part 33b is provided at the center in the circumferential direction of the first concave part 33a so as to further cave from the first concave part 33a, a convex part 33c is formed by forming curved surfaces that are convex outward from the first concave part 33a at both ends in the vertical direction of the first concave part 33a, the vertical width of the convex part 33c being the smallest at both ends in the circumferential direction and the largest at the center.SELECTED DRAWING: Figure 5 【課題】減圧吸収機能を有すると同時に高い強度を有するプラスチックボトルを実現する。【解決手段】胴部に、減圧吸収パネル部３３と、胴部基準面３４と、を備えるプラスチックボトルであって、減圧吸収パネル部３３は、胴部の上下方向に延在し、かつ、当該ボトルの中心軸を中心として周方向にねじれる形状で設けられており、第一凹部３３ａは、胴部基準面３４から当該ボトルの内側に向けて陥没し、第二凹部３３ｂは、第一凹部３３ａの周方向の中央に、第一凹部３３ａからさらに陥没するように設けられ、凸部３３ｃは、第一凹部３３ａの上下方向の両端部に、第一凹部３３ａから外側に向かって凸となる湾曲面が形成されたものであり、凸部３３ｃの上下方向の幅は、周方向の両端部において最も小さく中央部において最も大きいことを特徴とする。【選択図】図５
