Abstract
A first reservoir body ( ) includes two necks ( ). One neck ( ) carries a thrust piston pump ( ) including a medium outlet ( ). The other neck ( ) carries a closed second reservoir body ( ) including a second medium. When the closure ( ) is opened, the second medium is transferred into the first reservoir body ( ) where it is mixed with or dissolved in the first medium. Thereafter, the mixed media can be discharged by the dosing pump ( ) from the first reservoir body ( ) in discrete doses in sequence. Thus, the media are stored separately and are not merged until being discharged.
