Abstract
A dispenser (1) including a reservoir (4), a pump (6) and an atomizing nozzle (17) has on the nozzle (17) a germ barrier (22) in the form of a valve that opens and closes dependent on pressure. A further germ barrier (23) with a filter (54) acting as a seal in the connecting area between reservoir (4) and pump (6) is provided in a venting channel (21). Both units (2, 3) of the device (1), which are actuated against each other, are prevented from being pulled apart by a snap device (50). Germ penetration into the entire dispenser (1) can be effectively prevented.
