Abstract
Abstract A dispenser (1) has two facing and outwardly sealed reservoirs (2) for separate media components, as well as for each reservoir (2) a separate discharge pump (3), both discharge pumps (3) being simultaneously operable by means of a common handle (10). Thus, the components are separately sucked in and are kept separate up to a mixing zone located inside or outside the handle (10), but with respect to the use thereof are brought together at the latest possible time. The components can be brought together in a precisely dosed quantity ratio.
