1. A method for producing containers filled with a liquid filling material from blanks made of a thermoplastic material, comprising the steps of:

  • thermally conditioning a respective blank; and

    shaping the blank in a mold during a shaping phase to form and fill the container by introducing liquid filling material under pressure through a nozzle into the blank to axially and radially stretch the blank, the axial stretching being initiated by a pulsed injection of filling material into the blank in a targeted manner against a base of the blank, the blank being stretched only by the liquid filling material.
