ABSTRACT:
A disposable atomizer contains a cylindrical container for a medium to be atomized, particularly a pharmaceutical medium. The container is closed by a rubber plunger plug which has a central opening into which a closure ball is pressed. For discharging the medium, the container is pressed against an actuator which pushes the ball from the opening and thereby opens the container while, at the same time, the actuator forced down from a shoulder forms the plunger of a plunger pump formed thereby.
