Abstract
A dispenser (1) includes in a casing (2) with a volume-variable storage chamber (11) for the medium, a discharge closure (10), whose closure member (50) is located directly adjacent to the discharge nozzle (8) and whose pressure dependently operating control device (18) is arranged completely within the casing (2). The control device (18) is located on a support unit (5) separate from the casing (2) and defining ducts (28, 29, 38, 47) for two separate media. Thus, while achieving simple construction and assembly, a contamination of the stored medium can be prevented.
