Abstract

Procedure for the installation of closed and sterile hollow bodies of plastic material, of the type in which the extrusion of a tube of thermoplastic material whose interior is fed with sterile gas at low pressure and whose end is sealed in a sealed manner, is introduced the tube closed between the two semi-shells of a mold that closes to thus imprison a portion of the tube thus constituting a paraison, is drilled in the mold closed the paraison with the aid of a sterile hollow needle in relation to a source of high-pressure sterile gas, the insufflation of the paraison is carried out with the help of the high-pressure sterile gas so as to obtain the hollow body, the hollow body is removed after it has been partially decompressed, two parts of the mold are pinched inside the mold.
