Abstract
In order to enable application of a dry i.e. powdery or granulated active substance, said substance is kept apart from a liquid supply in a dispenser. The powder is discharged with the help of said liquid during application. The liquid serves as a carrier for the active substance and is mixed with the liquid to varying degrees prior to discharge. The dispenser (11) has a liquid chamber (21) in an ampoule (19) which is provided with a closure stopper (26) which can be pierced. The liquid flow which is released upon actuation penetrates into a medium storage chamber (43), is mixed with the medium (51) therein and exits via an opened discharge outlet (44) in the form of a spray mist, jet or drop.
