摘要

In a device for dosed delivery of fluid into a container (1), having liquid-filled storage chambers (3) and a hollow needle (4) for bringing liquid from each chamber into the container, the chambers are located in a drum magazine (11). The needle is fixed in a piston (5) guided parallel to the magazine axis in a housing (2), and is movable against spring pressure from a ready-for use position to a supply position with the needle tip projecting into the chamber.
