Abstract (en)
[origin: US5156307A] The dispenser has a circular mixing chamber (8) which is arranged immediately in front of a mixing nozzle (7). A first channel (15) leads to the mixing chamber (8) which is connected with a rising pipe which is immersed in the filled material of a squeezable container. Simultaneously, a second channel (9) leads into the mixing chamber which is connected to the air space above the filled material. A sieve arranged in the outlet channel (19) at a distance after the mixing nozzle which completely covers the outlet channel under the effect of the pressure of the filled material flowing out when the container (1) is squeezed. With release of the container, the sieve partially releases the outlet channel under the suction effect of the air return flow. With that, the container is rapidly ready for a renewed press sequence.
