Plastics material container

A plastics material container for the reception of beverages, said container having a mouth, a wall portion adjoining the mouth in a longitudinal direction (L) of the plastics material container and a base portion designed in the form of a standing face, wherein the plastics material container is formed in one piece, and wherein the base portion has an injection point—situated on an inside in a radial direction (R) with respect to a longitudinal direction (L)—on an outer wall of the plastics material container, a central area which surrounds the injection point, as well as a transition portion which extends from the central area to the wall portion, wherein the transition portion has in at least one radial direction (R) a curvature with a finite radius of curvature in at least one portion, and wherein the base portion includes a plurality of reinforcement ribs which starting from the central area extend in a direction of the wall portion, wherein the reinforcement ribs comprise a free form surface having support splines, wherein the support splines are at least tangentially continuous with an outer face of the base portion and wherein substantially all points of the free form surface have a finite radius of curvature, wherein the central area has a first dome structure which is arched in a direction of the mouth of the plastics material container, and wherein the injection point projects in the direction of mouth of the plastics material container in the longitudinal direction (L) of the plastics material container and merges directly into the first dome structure, and the first dome structure of the central area is adjoined in a radial direction on an outside by a second dome structure, wherein the second dome structure is arched in the direction of the mouth of the plastics material container, wherein a radius of curvature of the first dome structure is smaller at least locally than a radius of curvature of the second dome structure, and wherein a transition portion of the first dome structure merges into a transition portion of the second dome structure, wherein at least a transition portion of the base portion at a radius portion which is curved in a direction opposite the curvature of the first and second dome structures, and wherein the base portion comprises a plurality of standing face portions each having a substantially straight line course portion extending radially between the second dome structure and the support splines.
