ABSTRACT:
A metering device has a chamber of variable volume, closed at one end by a closure member; a link for the chamber with the outside, and a control for the variations in the volume of the chamber, making it possible to draw in or to discharge depending on whether the volume increases or decreases. The closure member is traversed by at least one duct emerging in the chamber and towards a container; selection elements are provided either for connecting the duct to the product container, or for closing the duct; a dispensing orifice is provided in the wall of the chamber, this orifice being equipped with a shut-off capable of being closed when drawing into the chamber and of being opened for dispensing.
