Abstract

Zur Ausbringung eines trockenen, d.h. pulverförmigen bis granulatartigen Wirkstoffes wird es in einem Spender gesondert von einem Flüssigkeitsvorrat aufbewahrt. Beim Applizieren wird das Pulver mit Hilfe der Flüssigkeit ausgetragen, die als Träger für den Wirkstoff dient und vorher mit ihm mehr oder wenig gemischt wird.To apply a dry, i.e. powdery up granular active ingredient, it is separated in a donor kept a liquid supply. When applying the powder discharged with the help of the liquid which acts as a carrier for the active ingredient serves and is mixed with it more or little beforehand.

Der Spender (11) weist einen Flüssigkeitsraum (21) in einer Ampulle (19) auf, die einen durchstechbaren Verschlußstopfen (26) aufweist. Der bei der Betätigung freigesetzte Flüssigkeitsstrom dringt in eine dann geöffnete Medienspeicherkammer (43), mischt sich mit dem darin vorliegenden Medium (51) und tritt über eine dabei geöffnete Auslaßöffnung (44) als Sprühnebel, Strahl oder Tropfen aus.

Figure 00000001
The dispenser (11) has a liquid space (21) in an ampoule (19) which has a pierceable sealing plug (26). The liquid flow released upon actuation penetrates into an then opened media storage chamber (43), mixes with the medium (51) present therein and exits as an spray, jet or droplet via an open outlet opening (44).
