Abstract

A first reservoir body (13) includes two necks (19, 20). One neck (19) carries a thrust piston pump (11) including a medium outlet (37). The other neck (20) carries a closed second reservoir body (14) including a second medium. When the closure (9) is opened, the second medium is transferred into the first reservoir body (13) where it is mixed with or dissolved in the first medium. Thereafter, the mixed media can be discharged by the dosing pump (11) from the first reservoir body (13) in discrete doses in sequence. Thus, the media are stored separately and are not merged until being discharged.
