Abstract: A hand-held device for apportioned delivery of sprayable substances, in particular inhaler medicaments, having a cartridge which is displaceable by pressing in a housing into the open position for delivery, and an indexing mechanism which is moved along by the cartridge during the opening stroke of the cartridge for registering and displaying delivery actuations which have been carried out, which indexing mechanism is disposed in a housing centrally below the opening-side end wall of the cartridge, overlappingly with respect to the valve tube of the cartridge. In order to configure a hand-held device of the type in question in a spatially advantageous manner with a simplified construction and such that it is more reliable in terms of handling, it is proposed to displace plate-shaped housing as a whole with the cartridge, except for a step-by-step indexing finger star disposed therein.

Abstract: The invention relates to a dispenser for pulverulent compounds contained in a separate pack, in particular compounds contained in a blister pack, wherein the pack has a container part and a tear-off container cover, wherein, furthermore, an air flow aspirated after removal of the container cover from the container part is at least partially aspirated through the container part. The container cover projects out of a tear-off opening of the dispenser for actuating purposes. The dispenser of the type in question is improved in a structurally simple manner such that functionally reliable handling is provided over the course of the inhaling operation. The air flow is aspirated laterally into the dispenser with respect to a tear-off direction of the container cover, and that the container cover closes the tear-off opening.

Abstract: The invention relates to a dispenser (1) for pulverulent substances (30), in particular medicaments, from a blister pack (25), dome-shaped cavities (26) of which that are disposed on a base layer (28) can, by movement in a dispenser housing (4), be brought step by step into an emptying position, in which they can be opened by means of a needle (31) and can be emptied by a suction air stream (a) leading to a mouthpiece (6). To achieve optimum emptying of the cavities, it is proposed that the needle (31) passes crosswise through both lateral walls of the dome (29) of the cavities (preferably parallel to the base layer 28) in order to form a through path to the mouthpiece for suction air.

Abstract: The invention relates to an inhaler (1) for powdery, especially medical substances (17), comprising an air duct (45) that leads to a mouthpiece (3), a reservoir (16) for the substance (17), and a moved dosing chamber (D) for apportioning a specific amount of substance from the reservoir (16) into the zone of a transfer point (U) to the air flow. A filling means (B) which charges the dosing chamber (D) similar to a shovel is moved towards the dosing chamber (D) so as to penetrate the substance supply. In order to create a simple design for such an inhaler in such a way that the same is easy and functionally safe to handle regarding apportioning a reproducible amount of substance, the shovel-type charging process performed by the filling means (B) is derived from a relative movement between the dosing chamber (D) and the reservoir (16).

Abstract: The invention relates to an inhalator (1) for powdery substances (33), especially medical substances. The inhalator comprises a substance reservoir chamber (27) and a metering chamber (34). The metering chamber is configured as a crossbore (35) of a rod (36) and can be displaced from a filling position (B) to a discharge position (E), in which discharge position (E) the metering chamber (34) is positioned in an air flow channel (21). The aim of the invention is to improve said inhalator, especially with regard to the filling or emptying of its metering chamber, even when particles of smallest dust-like grain size are used. For this purpose, at least a part of the reservoir chamber wall (28) is displaced in the direction of the rod (36) when the inhalator (1) is actuated.

Abstract: An inhaler for powdered, particularly medicinal substances, is formed with a suction air duct that extends to a mouthpiece, a reservoir for the substance, and an at least linearly movable dosing chamber for separating a specific amount of the substance from the reservoir and placing the amount into a transfer position from where it is transferred to a suction air flow. In order to charge the dosing chamber by separating a specific amount of substance from the reservoir, the dosing chamber can be rotationally moved in a superimposed fashion while being arranged eccentric to a corresponding axis of rotation. A closure slide element closes off the dosing chamber in the transfer position. When suction is applied, the closure slide element moves relative to the dipping plunger into a dose-release position, whereupon the dose of the powdered substance is transferred to the suction air stream formed in the suction air duct.

Abstract: An inhaler for powdery, in particular medical, substances is formed with a suction air channel, which leads to a mouthpiece. The inhaler also has a storage chamber for storing the substance and a linearly moving dosing chamber for apportioning a specified amount of substance from the storage chamber to a transfer point to the suction air flow. The aim of the invention is to obtain a structurally simple solution that makes it possible to eliminate adding an external air flow. To this end, a component of the suction air flow, which is located in the direction of extension of the dosing chamber, empties said dosing chamber.
