Abstract: A dry powder inhaler comprises a shell having upper and lower shell parts, and an inhalation piece, through which a user can inhale medicament. The inhalation piece is coupled to the lower shell part and the upper shell part is moveable between a closed configuration, coupled to the lower shell part and covering the inhalation piece, and an open configuration in which the inhalation piece is exposed. An actuation button is coupled to the lower shell part and biased by a first biasing mechanism acting between the actuation button and the lower shell part towards a projected position projecting from the surface of the lower shell part and moveable to a retracted position. Movement of the actuation button causes medicament to be dispensed for subsequent inhalation through the inhalation piece.

Abstract: There is disclosed an inhaler, such as a dry powder inhaler, comprising a shell having an upper shell part and a lower shell part, and an inhalation piece, such as a mouthpiece or nosepiece, through which a user can inhale medicament. The inhalation piece is coupled to the lower shell part and the upper shell part is moveable between a closed configuration in which it is coupled to the lower shell part and covers the inhalation piece, and an open configuration in which the inhalation piece is exposed. The inhaler also comprises an actuation button coupled to the lower shell part and biased by a first biasing device acting between the actuation button and the lower shell part towards a projected position in which it projects from the surface of the lower shell part and moveable to a retracted position. In use, movement of the actuation button from the projected position towards the retracted position causes medicament to be dispensed for subsequent inhalation through the inhalation piece.
