Abstract: The present invention relates to a clip (2) that is disposed in the lock section of dry powder inhaler devices (1) and that has a beak-shaped first end (4) with a retaining tab (3) at the end thereof, a housing (9) through which a pin (11) connected to the device body (10) at the center section thereof passes, and a second tab (8) at a second end (7) thereof, wherein the second end (7) of said clip (2) is composed of two pieces, namely an upper piece (5) and a lower piece (6), and said pieces (5, 6) are joined at the beak-shaped first end (4).

Abstract: The present invention relates to an inhaler device (1) with a guide gear (7) having teeth each comprising two sections with different profiles/surfaces. An upper section has an inclined/radius surface (3.1) to form a ratchet being engaged by a corresponding pawl (2) to provide an unidirectional rotation. A section close to a base of the guide gear has a flat surface (3.2) around which a strip-shaped blister (5) is rolled. This enables holding blister in a secure manner while providing unidirectional rotation of the gear.
