Abstract: A discharging nozzle for foamed material, especially whipped cream, is kept at a predetermined temperature even when a refrigeration machine which cools the device holding or producing the whipped cream is temporarily not operating. Thus, the discharge nozzle is kept substantially at the same temperature as the reservoir holding the whipped cream or as the machine producing the whipped cream. For this purpose the discharge nozzle is mounted in a solid cooled housing in heat transfer communication with a hollow jacket. The hollow jacket in turn is connected in heat communication to the device holding or producing the whipped cream. The hollow jacket is filled with a liquid which stores cold produced by refrigerating of the device holding or producing the whipped cream. The storing of the cold is accomplished by a change in the physical state of the liquid. The cold is then released to the nozzle during times when refrigeration is interrupted.
