Abstract
The invention concerns a method and a device for sterilising hollow bodies, such as containers, container preforms, tubes and various conduits. The invention is characterised in that it consists in guiding (15) a vaporisable sterilising agent over the walls of the hollow body (9), using guide means (7; 13) enabling the agent to be entirely deposited over the surfaces to be sterilised.
Claims32
A method for sterilizing a hollow body (9) having an opening (8) by depositing on a surface of the hollow body to be sterilized a sterilizing agent that is previously vaporized, comprising:
- vaporizing the agent outside of the opening of the hollow body;
- and
- distributing the vaporized agent on the surface to be sterilized by creating a gaseous current for guiding the vaporized agent toward the surface to be sterilized by use of a means of aspiration, which has an opening that is within the hollow body and opposite the opening of the hollow body.
A method for sterilizing a hollow body (38) having two openings by depositing on a surface of the hollow body to be sterilized a sterilizing agent that is previously vaporized, comprising:
- vaporizing the agent outside of one of the openings of the hollow body;
- and
- distributing the vaporized agent on the surface to be sterilized by creating a gaseous current for guiding the vaporized agent toward the surface to be sterilized by use of a means of aspiration, which has an opening that is within the hollow body and opposite the opening outside of which the agent is vaporized.
