The invention relates to a device for metering carbon dioxide snow, comprising a storage container and a discharge opening arranged in the base of the storage container. A horizontally and vertically movable base, by means of which the discharge opening can be opened and closed, is arranged in the region of the discharge opening. A horizontally movable cutting knife is vertically spaced from the base and can be moved into the interior of the storage container. Once the storage container is filled with carbon dioxide snow a metered amount of carbon dioxide snow present between the cutting knife and the base is cut off by the cutting knife and compacted by vertical movements of the base and is then discharged by the base moving into the open position.
