Abstract
The invention relates to a dispenser, especially a disposable atomizer (25), with a dispenser unit (11). Said unit contains a media container (12) which also forms the pump chamber and which is sealed by a piston-type stopper (14). When activated, said piston-type stopper is punctured by a hollow needle (16). The outlet nozzle (20) surrounds the dispenser unit to a large extent. The dispenser unit (11) can be introduced into an activating unit (26). According to one configuration, this activating unit is pin-shaped with a loading chamber (29). The dispenser unit is held in place by an activating push rod (30) which can be longitudinally displaced when activated by turning (33) and is prestressed by a spring (36). The dispenser is activated by a trigger device (39). The dispenser unit (11) can also be changed after use.
