Method of automatic manufacture of closed, internally sterile hollow bodies |
摘要 |
The process of the invention essentially consists in supplying sterile gas to an extruded parison confined between the two shells of a mould, this sterile gas being sequentially applied at a first pressure slightly higher than atmospheric pressure, at a second pressure much higher than the first pressure in order to inflate the parison, and at a third pressure which is much lower than the second pressure and corresponds to the desired inflating pressure of the hollow body to be formed.
