Abstract: A device for filling containers includes a filling spout fitted with a valve system for minimizing the formation of drops after being closed. The valve system includes a cylindrical central valve moveably mounted in a main tubular valve. A control system enables, on the one hand, the main valve to move relative to a main seat of the spout in order to open or close the discharge aperture of the spout, and on the other hand, to move the central valve relative to a secondary seat of the main valve in order to open or close the secondary aperture of the latter. The lower edge of the main valve is provided with radial grooves extending over the inner surface thereof, wherein in the grooves the filling substance on the lower edge of the central valve can migrate via capillarity.
