Summary:To provide a synthetic resin bottle reliably allowing decompression deformation of a protrusion part.SOLUTION: A synthetic resin bottle 1 has a mouth 2 for spouting a content, a shoulder part 3 integrally connected to the mouth 2, a shank 4 integrally connected to the shoulder part 3 and a bottom part 5 integrally connected to the shank 4, and is formed to exhibit a decompression absorption function by displacement of the bottom part 5 to the inward direction of the shank 4 with decompression of the inside. In the synthetic resin bottle 1, the bottom part 5 has an annular peripheral edge part 10, an annular protrusion part 13 which is provided inside the peripheral edge part 10 in the radial direction, protruded downward from the peripheral edge part 10 and serves as an earthing part of the synthetic resin bottle 1, while displaces in the inner direction of the shank 4 with the decompression inside the synthetic resin bottle 1 and makes the peripheral edge part 10 function as the earthing part, a caving recessed part 15 provided inside the protrusion part 13 in the radial direction and caved inward the shank 4, and multiple parting grooves 20 provided at the protrusion part 13 and parting the protrusion part 13 in the circumferential direction.SELECTED DRAWING: Figure 2 【課題】突条部を確実に減圧変形させることが可能な合成樹脂製ボトルを提供することである。【解決手段】内容物を注出する口部２、口部２に一体に連なる肩部３、肩部３に一体に連なる胴部４及び胴部４に一体に連なる底部５を備え、内部の減圧に伴って底部５が胴部４の内部方向に変位して減圧吸収機能を発揮するように構成された合成樹脂製ボトル１であって、底部５が、環状の周縁部１０と、周縁部１０より径方向内側に設けられ、周縁部１０より下方に突出して合成樹脂製ボトル１の接地部として機能する一方、合成樹脂製ボトル１の内部の減圧に伴って胴部４の内部方向に変位して周縁部１０を接地部として機能させる環状の突条部１３と、突条部１３より径方向内側に設けられ、胴部４の内部方向に向けて陥没する陥没凹部１５と、突条部１３に設けられ、突条部１３を周方向に分断する複数の分断溝２０と、を有することを特徴とする合成樹脂製ボトル１。【選択図】図２
