Abstract
A synthetic resin container, in which the bottom parthaving a bottom plate partwhich is present at the center of the bottom part and a peripheral partwhich is positioned at the periphery of the bottom plate part, in the peripheral part, a grounding parthaving an inside slopewhich rises outwardly of the container with the outer peripheral edge of the bottom plate partbeing the start point and an outside slopewhich continues to the side surface of the bottom partis formed, and when a load is applied in the axial direction in the state where the container stands upright on the grounding surface G, the shape of the bottom partchanges reversibly such that the bottom plate partis depressed inwardly to the container. As a result, it is possible to avoid deformation of a container into an unintended shape by buckling or the like even if a load is applied to a container in the axial direction, and to ensure the rigidity of a container against a load in the axial direction.
