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. The permissible period of use of a metering apparatus which can be used for a plurality of supply containers can be reliably viewed.
A mechanical counter for a metering apparatus having a first housing portion and a second housing portion coaxially arranged which are rotated relative to each other when the metering apparatus is operated, the mechanical counter comprising:
A metering apparatus having two coaxially arranged housing portions which are rotated relative to each other when the metering apparatus is operated, the metering apparatus having a mechanical counter comprising:
A metering apparatus having two coaxially arranged housing portions which are rotated relative to each other when the metering apparatus is operated, the metering apparatus having a mechanical counter comprising a screwthread spindle mounted in bearing means on one of the housing portions in a peripheral region thereof so that it is rotated by movement of the other housing portion, and a cursor movable, by the screwthread, relative to marker means, the arrangement being such that movement of the cursor with respect to the marker means provides a measure of the number of operations of the apparatus.
