Indicating device
First Claim
1. A device for dispensing metered dosages of a substance comprising:
- a dispenser housing comprising a support block;
a container holding a plurality of metered dosages of substance, said container comprising a valve stem extending from said container, wherein said container and said valve stem are moveable from a disengaged position, wherein said valve stem is not coupled to said support block, to an engaged position, wherein said valve stem is coupled to said support block, and wherein said valve stem defines a longitudinal axis;
an indicating device coupled to said dispenser housing, wherein said indicating device is non-rotatable relative to said dispenser housing about said longitudinal axis, said indicating device comprising an indicator housing having an opening; and
an actuator coupled to said container and moveable with said container from said disengaged position to said engaged position, wherein said actuator is inserted through said opening in said indicator housing when said container and said valve stem are moved to said engaged position, wherein said actuator interfaces with said indicating device through said opening such that said actuator is non-rotatable relative to said indicating device about said longitudinal axis and such that said actuator is maintained in an operable position relative to said indicating device.

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.
