An inhalation device is provided by means of which material in powder form can be inhaled. The device comprises a body 55 defining a reservoir 56 for medicaments in powder form, an outlet 57 through which a user can inhale and a dosing member 53 with at least one metering recess 65 formed therein. The dosing member 53 is moveable between a position in which the at least one metering recess 65 communicates with the reservoir 56 to receive a dose of powder therefrom and a position in which the at least one metering recess 65 communicates with the outlet 57 to permit the user to inhale the dose. The at least one metering recess 65 is formed in a face of the dosing member 53, the said face being mounted in contact against a similar mating face 60 of the body 55 at the lower end of the reservoir 56. At least one moveable weight may be incorporated within the device, adapted to strike an anvil surface when the device is shaken.
An inhalation device comprising a body forming a reservoir for powder medicaments, an outlet through which a user can inhale, and a dosing member with at least one metering recess formed therein, the dosing member being movable 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 being formed in a first sealing face of the dosing member, said face being mounted in contact against a second sealing face of the body, characterised in that said first sealing face of the dosing member and said second sealing face of the body have highly polished smooth surfaces which form a contacting face to face seal in which said sealing faces adhere to each other sufficiently to exclude air and moisture while being slidable relative to each other, said reservoir comprising medicament in powder form therein.
An inhalation device comprising a body defining a reservoir for powder medicaments, said reservoir having an upper and lower end, an outlet through which a user can inhale and a dosing member with at least one metering recess formed therein, the dosing member being movable between a position in which the at least one metering recess communicates with the lower end of 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 being formed in a first receiving face of the dosing member, said face being mounted in contact against a second sealing face of the body at the lower end of the reservoir, characterised in that said first sealing face of the dosing member and said second sealing face of the body are sealing faces with highly polished surfaces which adhere to each other sufficiently to exclude air and moisture while being slidable relative to each other.
