CA 2383425

A powder inhaler comprises a powder container (1), an air channel (11), a metering member (3) equipped with a dosing recess (5), an actuating means (7) for the displacement of the metering member (3) between the filling and the inhalation position, and a closure element (16) for plugging the air channel (11) in a substantially water-proof manner when the metering member (3) is in the filling position and opening the air channel (11) when the metering member (3) is in the inhalation position. When the inhaler is not in use, the closure element (16) prevents moisture and dirt entering the sensitive parts of the device.

Lorsque l'on n'utilise pas l'inhalateur, le dispositif de fermeture (16) empêche la vapeur d'eau et la saleté de pénétrer dans les éléments sensibles de l'inhalateur.
