Definitions
- the present invention relates generally to the field of the manufacture of containers made of thermoplastic material such as PET or PEN by a blow molding process or stretch blow molding from a preform (such that a preform or intermediate container), and more specifically concerns improvements made to the blowing installations, using a fluid under pressure, containers from blanks of thermoplastic material whose body is enclosed in a mold of blowing and which have been previously heated in a thermal conditioning furnace, said installations comprising a nozzle comprising an end shaped to be in sealed functional relation with the neck of the blank.
- the nozzle is arranged to be movable, in all or part, axially above the blow mold between a raised position or raised position in which the nozzle is not functional (opening and closing of the mold for loading a roughing and unloading of the molded container) and a low position or blowing position in which the end of the nozzle cooperates sealingly with the neck of the blank, or with the face of the mold above which protrudes the neck of the blank and wherein said low position said nozzle is functional.
- Blowing installations are known in which the end of the nozzle, in the operative position, cooperates positively with the neck of the blank and is either abutted sealingly against the rim (edge) of the neck of the blank, or is tightly fitted in or on the neck of the blank.
- Blowing installations are also known in which the end of the nozzle is shaped like a larger bell than the neck of the blank and caps the latter by bearing against the face of the mold on which the collar of the blank protrudes (see for example the document FR 2 764 544).

- a fluid generally air
- a mean pressure for example 12 ⁇ 10 3 Pa
- a blowing phase properly.
- said under a high pressure for example 40 x 10 Pa
- a drawing rod usually accompanied by axial stretching mechanically by means of a drawing rod and finally an exhaust phase with evacuation of the pre-blowing / blowing air.
- control system of the exhaust by a solenoid valve adds a control complexity of the blowing process and increases the manufacturing costs of such a blowing installation.
