Dry-powder inhaler

A dry-powder inhaler comprising:

• a body containing a chamber and a mouthpiece provided with a dispensing orifice through which the user inhales,
• a reservoir containing a dose of dry powder to be inhaled and comprising a lateral outlet opening, said reservoir being movable between an non-loaded position, in which it is at least partially disposed outside said chamber, and a loaded position, in which it is entirely disposed in said chamber, the diameter of said reservoir being less than the diameter of said chamber, so that, in the loaded position, said reservoir can move in said chamber, said body comprising tangential channels adapted to bring a flow of inhalation air tangentially into said chamber, which, during inhalation, generates an orbital movement of said reservoir in said chamber, in the loaded position,
• an actuating member for moving said reservoir from its non-loaded position towards its loaded position,
• characterized in that said reservoir includes a closure element which is independent from said body displaceable and/or deformable with respect to said reservoir between a closed position of said lateral outlet opening and an open position of said lateral outlet opening, said closure element being in the closed position when said reservoir is in the non-loaded position, and being in the open position when said reservoir is in the loaded position.

• an actuating member for moving said reservoir from its non-loaded position towards its loaded position,
• characterized in that said reservoir comprises an upper reservoir portion provided with an upper lateral opening and a lower reservoir portion provided with a lower lateral opening, said upper reservoir portion being axially movable relative to said lower reservoir portion, said upper and lower lateral openings being axially offset when said reservoir is in the non-loaded position, and being aligned to form an open lateral opening when said reservoir is in the loaded position.
