Abstract
A hand-held device for metered dispensing of sprayable substances, in particular inhaler medicaments, includes a housing and a cartridge which can be displaced into a dispensing position by a pressure application relative to the housing, wherein the housing has a mouthpiece, wherein the cartridge can be displaced initially into a ready-to-dispense position and a dispensing spray process can be triggered by sucking in, wherein the displacement of the cartridge can be executed by tensioning a spring supported on the housing and acting on the cartridge. The spring is displaced into the position to perform a spraying process, but is hindered by a counterforce that can be deactivated by application of a negative pressure through the mouthpiece of the hand-held device A valve flap is moved by the negative pressure and cancels a mechanical block of the movement of the cartridge.
