Inhalation device
First Claim
1. An inhalation device for use with a medicament pack to be received in the device, in which pack a plurality of containers for medicament in powder form are defined, the device comprisinga body which is generally circular in plan view and has a circular rim and an axis of general rotation symmetry, and a cover mounted on said body for rotational movement about the axis of general rotational symmetry between a first position and a second position;
- an indexer for indexing each of the containers successively to an opening station when a medicament pack is received in said device;
an opener for opening each of the containers at the opening station when a medicament pack is received in said device;
and a mouthpiece formed in said body and located substantially within the generally circular plan view, the mouthpiece communicating with the opened container when a medicament pack is received in said devise, through which mouthpiece a user can inhale medicament in powder form from the opened container, the mouthpiece being exposed for use by movement of said cover from said first position to said second position;
wherein the cover is mounted on said body such that rotational movement thereof slides the cover over the body between the first and second positions, and wherein the cover comprises a side wall portion lying generally perpendicular to said axis and over an adjacent portion of said body, and an arcuate edge portion which extends from said side wall portion and partially around said rim.
