摘要:
1. An inhaler with a mouthpiece upstream of the medicament doses, comprising a circular disk base having at least one or a plurality of sealed cavities containing medicament, a foil portion comprising two sides, one side being attached to the base for sealing the medicament within the cavity, a separating element which is attached to the other side of the foil portion for separating the foil portion from the cavity, the separating element having a first end and an opposite second end, wherein the separating element is movable to an intermediate tilted position in which said first end is moved-away from the cavity, wherein the separating element is further movable from the intermediate tilted position to a removed position in which also said second end is moved-away from the cavity so that the foil portion is removed from the cavity which is thereby uncovered so that medicament contained therein is enabled to become entrained in a fluid flow. An actuator removes the separating element of the foil portion from the cavity by impacting upon it so it forms part of the air flow path. The separating element can be return to its original position once the medicament has been removed from the cavity.
