Abstract
An aerosol dispenser for use with an aerosol vial. The dispenser contains an assembly that indicates the quantity of doses dispensed from or remaining in the aerosol vial. The assembly comprises a rotatable indicator comprising a circumferential rack that is engaged by a worm-gear. Reciprocal movement of an aerosol vial within the dispenser causes rotation of the worm-gear which in turn causes rotation of the rack.
