摘要：The invention relates to a self-closing valve for dispensing a free-flowingproduct. The valve has a valve membrane with an opening for dispensing and an encirclingedge at the outer perimeter, wherein the valve membrane is able to switch between aclosed mode, a dispensing mode, and a back suction mode due to pressure differences

produced. There is also a stopper on which the valve membrane lies in the closed modeand in the back suction mode so that the dispensing opening is closed, and from which itis lifted in the dispensing mode. The valve includes a stop ring, on which the encirclingedge of the valve membrane lies as a seal during the closed mode and from which it islifted in the back suction mode, and a lateral channel that extends axially, wherein at leastparts of the encircling edge are opposite the valve membrane, and the encircling edge ismovable axially on the lateral channel to switch to back suction mode, in which a gap iscreated between the encircling edge and the lateral channel.
