Abstract
A medicament dispensing device for dispensing metered dosages of a medicament includes an actuator housing having a longitudinally extending cavity and a container disposed in the cavity and having a cylinder with a first outer diameter. The cylinder is adapted to hold the medicament. The container is reciprocally moveable relative to the actuator housing along a longitudinal axis. An indicating device includes an indicator housing having a tubular portion connected to said container, with the indicating device being reciprocally moveable with the container relative to the actuator housing. The tubular portion has a second outer diameter that is of substantially the same diameter as the first outer diameter. A longitudinally extending side wall has a viewing window formed therein. An indicator is rotatably mounted in the indicator housing, with a surface thereof having indicia visible through the viewing window.
