  • Patent number: 11369760
    Abstract: The invention is directed to an inhalation atomizer comprising a counter and a blocking function. Counter rotates each time the atomizer is actuated. The blocking function includes a first protrusion on the counter and a second protrusion on a lower unit of the atomizer. Once the predetermined number of actuations has been achieved, the first protrusion encounters the second protrusion and prevents further rotation of the counter so that the atomizer is blocked from further use.

  • Patent number: 6149054
    Abstract: A metering apparatus for metering for example a medicament requires a device with which the number of metering portions is displayed. The known display devices however are not suitable for a metering apparatus having two housing portions which are rotatable relative to each other. The mechanical counter for a metering apparatus of that kind comprises at least one spindle with rotary locking, whose axis extends in parallel relationship with the axis of the metering apparatus and which is disposed in the region of a peripheral surface of the apparatus. The spindle is automatically driven by way of a transmission assembly when the metering apparatus is actuated. The number of metering portions already discharged and the number of petering portions permitted in total is quasi-continuously displayed by the mechanical counter. The transmission ration of the transmission assembly can be designed to cover a wide range. The cursor serving for display purposes can be reset on the spindle.
