Title:
HIGH-PRESSURE DEVICE FOR CLOSING A CONTAINER
Document Type and Number:
WIPO Patent Application WO2004048783
Kind Code:
A3
Abstract:
The invention relates to a very compact device and to a method for closing a container by means of a rotational symmetric lifting system, which contains a working piston and a guide cylinder and is operated essentially using the same fluid that is placed inside the container while serving as a process medium. The front face of the working piston forms, at least in part, the closure part of the container or is joined to the closure part in a fixed manner. Ideally, a supercritical fluid is used both as a working medium for driving the piston and as the process medium.
