A method for producing a container (2) from a blank (3) in a mould (1) provided with a wall (4) and a mould bottom (8) that is movable relative to the wall (4) between a retracted position and a deployed position, the method including: a phase of introducing the blank (3) into the mould; a preblowing phase including the injection, into the blank (3), of a fluid pressurised to a so-called preblowing pressure, a blowing phase following the preblowing phase and including the injection, into the blank (3), of a fluid pressurised to a so-called blowing pressure greater than the preblowing pressure; a boxing phase including the displacement of the mould bottom (8) from the retracted position thereof to the deployed position thereof, initiated after the pressure in the blank (3) has reached the blowing pressure.
