Dispensing device
First Claim
1. A dispensing device comprising:
- a container having a cylindrical side wall, a bottom, a top and a valve stem extending from said top, said container comprising a medicament;
a dispenser connected to said valve stem, wherein said container and said dispenser are moveable relative to each other along a longitudinal direction wherein said container dispenses a metered dosage of said medicament;
an indicating device comprising;
a housing comprising a circumferential skirt extending in said longitudinal direction and surrounding said cylindrical side wall of said container adjacent said bottom of said container;
an indicator member rotatably mounted in said housing about a longitudinal axis extending in said longitudinal direction, said indicator member comprising a plurality of teeth extending from a bottom of said indicator member in said longitudinal direction;
a drive assembly rotatably mounted in said housing about a rotation axis lying substantially perpendicular to said longitudinal axis, said drive assembly comprising a drive member selectively engaged with said plurality of teeth of said indicator member and a ratchet wheel coaxially mounted with said drive member; and
a pawl member selectively engaged with said ratchet wheel.

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.
