  • Patent number: 6877672
    Abstract: The object of the invention is to provide a method and a dispenser in which, compared with known dispensers, the fluid path design is simplified. The dispenser has a medium reservoir (19) containing a medium to be discharge during one discharge stroke of the dispenser (11). For this purpose a feed fluid flows through the medium reservoir and discharges the medium through a reservoir discharge opening. For producing a discharge stroke, the dispenser has an actuator (25), whose actuation at least indirectly leads to an impact spike (29) penetrating from the outside into the medium reservoir (19), so as to produce a connection between a pump (40) for a feed fluid and the medium reservoir. As a result of the pressure of the feed fluid flowing into the medium reservoir, at a point in the medium reservoir (19) differing from the entry point of the impact spike (29), an opening is formed.
