Abstract: A method for packaging a liquid to semi-solid substance under a vacuum inside a variable-capacity container closed by a dispenser member that prevents ingress of air, includes at least a stage in which the dispenser member is fixed in sealed manner on the container filled with the substance. The fixing takes place while the container is inside an enclosure in which an air vacuum is maintained. Apparatus for implementing the method includes, for example, a ring suitable for bearing downwards in sealed manner on the open top of a socket containing the container, thereby enabling the enclosure to be established. A device is provided therein for sucking out the air, and also for fixing on the dispenser member. It is possible to obtain like this dispensers that are particularly advantageous, particularly when the dispenser member is a precompression pump.
