The funnel is arranged at the outer end of a bar. For each mouthpiece in the conduit (10) between the container and the mouthpiece is coupled a check valve (14g,14h). - In the conduit between the check valve and the mouthpiece is connected a cylinder/piston unit (8), which with the check valves forms a suction pressure pump, and whose piston (14b) is loaded by a spring and has a specific stroke length. Connected to the piston operatively is a component which at each spraying operation against or with the effect of the spring imparts to the piston a sucking spraying movement. |
