ABSTRACT:
A device for reducing the quantity of oxygen in the space above the filling in a container before closing of the container, in which a vacuum is formed in the space, then a compressed gas is blown into the container in a direction running obliquely to the vertical axis of symmetry of the container and again a vacuum is formed in the space, these steps being repeated if necessary. Valving is provided in the fixed housing within which are formed, coaxially with a central column, an inner chamber and an outer, essentially cylindrical chamber enclosing it. One chamber is connected to a vacuum source and the other chamber to a source of the gas. One head face of each chamber has a plurality of openings at specific angular distances from each other and disposed on an inner and an outer circle respectively. Fixed on the central column is a disc in sealing fashion against the head faces. Two series of openings with equal angular distances from each other are formed on an inner and outer circle, respectively, the radii of these inner and outer circles being virtually equal to those of the first-mentioned inner and outer circle.
