Patent ID: 6948495

Claim:
A manually actuatable inhaler device allowing actuation before inhalation by the user, comprising a container for powdered medicament; an inhalation channel through which air can be drawn via a mouthpiece; a movable metering member for metering a dose of powder in a first position, and for transferring a metered dose of powder into the inhalation channel in a second position; a depressible actuator for the displacement of the metering member between the first and the second position; a multiple dosage preventing means for locking the depressible actuator after it has been used such that the actuator is unlocked only upon inhalation comprising a projection communicating with the actuator, a passage in which the projection moves when the actuator is depressed, and a blocking element which, after the device has been actuated, by means of gravitational force moves to a position where it blocks the passage, and which by means of an inhalation force moves to a position where it opens the passage.
