USPTO Abstract

A medicament dispenser for use with at least one medicament carrier carrying multiple distinct medicament dose portions. The medicament dispenser comprises a dispensing mechanism actuable for dispensing the dose portions carried by the at least one medicament carrier; a mouthpiece and a cover for the mouthpiece. The cover being movably mounted to the dispenser for sequential movement from a closed position in which the mouthpiece is at least partially covered, to an open position in which the mouthpiece is uncovered, via a first position, and optionally via a second position between the first position and the closed position that includes the closed position. The cover is adapted to couple with the dispensing mechanism such that movement of the cover from the closed to open position via the first position results in actuation of the dispensing mechanism. A medicament dispenser is also provided comprising a patient manual interface, a rotation control member 120, a driving plate 110, to drive stepwise advancement of dose portions to a dispensing station for inhalation by a patient, the driving plate comprising a camming feature and ratchet teeth and a body 130 comprising a slot. Wherein the rotation control member is driven between a rest state and an actuated state via an intermediate state by reciprocal movement of the patient manual interface between a rest and actuated state.
