An extrusion blow-molded plastic container, for example, a plastic bottle, is described which has a container body having a longitudinal axis, a longitudinal end sealed by a container bottom, another longitudinal end adjoining a container neck provided with a pour opening, and a container shoulder. The container body has at least one deformable section which is made flat and which extends over a large part of an axial length of the container body and in the peripheral direction. The deformable section which has been made flat has two longitudinal sides which run essentially in the axial direction and which border regions of the container body which have a greater stiffness than the deformable section.
