An inhalation device is provided by means of which material in powder form can be inhaled. The device comprises a body defining a reservoir for medicaments in powder form, an outlet through which a user can inhale and a dosing member with at least one metering recess formed therein. The dosing member is moveable between a position in which the at least one metering recess communicates with the reservoir to receive a dose of powder therefrom and a position in which the at least one metering recess communicates with the outlet to permit the user to inhale the dose. The at least one metering recess is formed in a face of the dosing member the said face being mounted in contact against a similar mating face of the body at the lower end of the reservoir At least one moveable weight may be incorporated within the device, adapted to strike an anvil surface when the device is shaken.

Inhalation device

Inhalation device comprising a body (,) defining a reservoir (,) for medicament in the form of a powder, an outlet (,) through which a user can inhale, and a dosing member (,) with at least one metering recess formed therein. The dosing member (,) is moveable between a first position in which the at least one metering recess communicates with the reservoir (,) to receive a dose of powder therefrom and a second position in which the at least one metering recess communicates with the outlet (,) to permit the user to inhale the dose. The at least one metering recess is formed in a face of the dosing member which is urged into contact against a similar mating face of the body at the lower end of the reservoir to form a dynamic seal. At least one of the faces (,) is made of a flexible material having a hardness of less than 80 Shore A.
