Summary:To provide a synthetic resin container which achieves both improvement of side surface rigidity of a trunk part and improvement of buckling strength by an annular recessed rib.SOLUTION: A synthetic resin container 1 comprises a mouth part 2, a barrel part 4 formed into a cylindrical shape, and a bottom part 5. On the barrel part 4, annular recessed ribs protruding radially inward and annularly extending in a circumferential direction are formed. At least one of the annular recessed ribs is an annular recessed rib 10 with a bent shape which comprises a bent shape part 11 bent to protrude toward either one side of the mouth part 2 side or the bottom part 5 side at a local position in the circumferential direction.SELECTED DRAWING: Figure 1 【課題】環状凹リブにより、胴部の側面剛性の向上と座屈強度の向上とを両立させることが可能な合成樹脂製容器を提供する。【解決手段】合成樹脂製容器１は、口部２と、円筒状に形成された胴部４と、底部５と、を備えている。胴部４には、径方向内側に突出しているとともに周方向に環状に延在している環状凹リブが形成されている。前記環状凹リブの少なくとも１つは、周方向の局所的な位置に口部２の側または底部５の側のいずれか一方側に向かって凸状に屈曲する屈曲形状部１１を備えている、屈曲形状付きの環状凹リブ１０である。【選択図】図１
