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.
