Embodiment Construction

[0033] Figures 1 to 12 A first embodiment of the inhaler is described. In this first embodiment, the inhaler 100 has a body 110 which is hollow and has upper and lower openings. The upper opening is at least partially closed by a panel portion 120 fixed to the body, while the lower opening is closed by a closing member, such as a shutter 150 , pivotally mounted on the body 110 . A sliding member 140 having a gear train is interposed below the plate portion 120 . Advantageously, the panel portion 120 has guide means, such as rails 129, cooperating with protrusions 149 of the sliding member 140 for guiding the translational movement of said sliding member. A pivoting cover 130 is assembled over the panel portion 120 . The cap 130 has a dispensing aperture 131 preferably formed at the mouthpiece around which the user will surround his mouth for inhalation. Thus, as especially in figure 1 As seen above, the device according to this first embodiment consists of five main part...

Abstract

A dry-powder inhaler (100; 200) comprising: a body (110; 210) forming a dispersion chamber (111; 211); a dispenser orifice (131; 231) through which the user inhales; a loading opening (121; 220) that receives a capsule (10) containing a dose of dry powder for inhaling; and capsule opening means (140; 265) for opening a capsule inserted into said loading opening and emptying said dose of powder into said dispersion chamber; said body (110; 210), at least at one wall of said dispersion chamber, being made of a tinted transparent material that is adapted to filter UV rays, at least in part, and to make it possible to see the inside of the dispersion chamber while masking, at least in part, residues of powder that are stuck to said at least one wall of tinted transparent material.

Description

technical field [0001] The present invention relates to a dry powder inhaler. Background technique [0002] Inhalers are well known in the art. There are different kinds of inhalers. A first type of inhaler comprises a container containing multiple doses of powder, said inhaler being provided with metering means which detach a dose of the powder from the container at each actuation to carry the dose of powder into the discharge duct , to assign to consumers. Another type of inhaler consists in arranging doses of powder in individual pre-dose containers and then opening one of these containers each time the inhaler is actuated. This implementation ensures a better tightness of the powder, since each dose is only opened at the moment it is expelled. To realize these individual containers, various variants have been proposed, such as an elongated strip of blisters or several blisters arranged on a rotating disc. Any type of inhaler described above and existing has advantag...
