Mold with raised land for manufacturing containers

A molding assembly for manufacturing a container having a body and a bottom provided with a peripheral base that extends essentially perpendicularly to the body starting from a lower end of the body, the molding assembly starting with a blank to manufacture the container, the molding assembly comprising:

• a wall having an inner surface that determines at least in part the impression of the body of the container and that delimits a cavity that extends around a central axis, with the inner surface ending, at a lower end, in an opening around the central axis;
• a mold bottom configured to move in relation to the wall between an extended position, in which the mold bottom is separated from the opening, and a retracted position, in which the mold bottom blocks the opening, the mold bottom having an upper surface that defines a base surface bearing the impression of the base of the container and that extends vertically perpendicular to the opening,
• wherein the upper surface of the mold bottom defines a peripheral surface that corresponds to a join between the base and the body of the container, the peripheral surface extending into the lengthening of the base surface around the base surface and ending by a raised edge in relation to the base surface,
• in the extended position of the mold bottom, the raised edge extends vertically perpendicular to the opening, and
• in the retracted position of the mold bottom, the raised edge extends in the vicinity of the opening.
