Abstract:
1. Plastic container, characterized in that it comprises: a rigidified body, a bottom extending to a lower end of the container and comprising: an annular base extending substantially perpendicular to the body in the prolongation thereof; an annular step extending from the base towards the interior of the container, a recess at the center of the bottom projecting towards the interior of the container, wherein the recess includes a conically shaped side wall having a smooth-walled lower conical portion, a smooth-walled upper conical portion having a narrower shape than the lower conical portion, and a recessed portion extending completely around the recess along the side wall in a circumferential direction so as to divide the upper and lower conical portions from each other, a deformable annular membrane, in the form of a curved surface having a radius of curvature substantially continuous and symmetrical of revolution around a main axis of the container extending substantially perpendicular to the body between the step and the recess, and wherein the membrane has a circular outer edge at a junction with the step, and the membrane has circular inner edge at a junction with the recess.
