ABSTRACT OF THE DISCLOSURE A pouring spout having an inlet portion and an outlet por- tion with an outlet end. A valve is mounted in the inlet portion and a device is provided for automatically opening or closing the valve as the spout is inserted in or withdrawn from the filling neck of a con- trainer to be filled. The valve opening or closing device comprises an actuating member connected to the valve, which number is slidable relative to the outlet portion. A spring normally biases the actuating member to a rest position where the valve is closed. Insertion of the spout in the filling inlet of the container causes the actuating member to move and to open the valve. Preferably the degree of opening of the valve is controlled in order to achieve varied flow rates. A hollow rib is provided on the exterior of the pouring spout to provide an air vent into a filling container. -23-
