Abstract
A dispenser for dispensing metered dosages of a substance from a container includes a dispenser housing having a top, a bottom, and a wall defining an elongated cavity open at the top and extending along a longitudinal axis. An indicating device includes a face member defining a viewing window. The face member is snap-fitted to the dispenser housing wall. The indicating device further includes an indicator member having a surface visible through the viewing window. The surface includes dosage indicia. The indicator member is rotatable about an axis substantially perpendicular to the longitudinal axis. An indicator actuator has at least a portion disposed in the cavity. The actuator is adapted to be moved by an actuation of the container, with the actuator adapted to rotate the indicator member upon a predetermined number of actuations of the container.
