Abstract: Disclosed is a container perform made from plastic material, including: a body; an open neck that extends from the body from which it is separated by a radially projecting flange; a bottom that closes the body opposite the neck; the body having a concave portion in axial cross section, where: B≤0.9·A 0.5.C≤C′≤0.95.C in which A is the overall diameter of the body, measured below the flange; B is the outer diameter of the bottom, measured at the junction of same with the body; C is the cumulative height of the body and the bottom, measured from the flange; C′ is the height, measured axially, of the concave portion of the body, and the concave portion has, in axial cross-section, on an outer surface, an outer radius of curvature RE such that: 1.5.0≤RE≤10.C

Abstract: A method for producing a container provided with a base, in a mold that includes a base with a base block with a raised molding face and a central opening, and an insert mounted in the central opening. The insert has an end face with the imprint of a central area of the base of the container, movable between: a retracted position with the end face extending in the extension of the molding face, thus completing therewith the imprint of the base of the container; a protruding position with the insert protruding relative to the central opening. A step of boxing the central area of the base of the container includes moving the insert to the protruding position to exert pressure against the central area of the base and increase the clearance of the central area relative to the clearance at the end of the blowing.
