The invention relates to a dispensing device for dispensing flowable materials from cartridges, whereby the dispensing device comprises a base body, a connecting element for a gas cartridge on the base body, a valve element for controlling a gas flow from the gas cartridge, and a gas-permeable channel connecting the connecting element to the valve element, whereby at least one evaporation container is arranged in the gas-permeable channel such that the gas flow from the gas cartridge is guided through the evaporation container, at least over regions thereof. The invention also relates to the use of a dispensing device of this type for expelling a flowable material from a cartridge, in which an evaporating liquid gas from a gas cartridge is guided into the evaporation container and the evaporated gas is guided from the evaporation container via a controllable valve element to a feed plunger of the cartridge, whereby the gas pressure propels the feed plunger and the flowable material is expelled from the cartridge by means of the advancement of the feed plunger.
