Indicating device
DCFirst Claim
1. A dispensing device for dispensing metered dosages of a medicament from a container:
- a dispenser housing comprising a support block having a well, said support block defining a longitudinal axis;
an indicator housing disposed at least partially around said support block, said indicator housing engaged with said dispenser housing so as to be non-rotatable about said longitudinal axis;
an actuator comprising a central, cylindrical hub portion adapted to be engaged by the container and centered about said longitudinal axis, said actuator moveable along said longitudinal axis relative to said indicator housing, said actuator comprising a resilient arm;
a drive gear rotatably disposed in said indicator housing, wherein said drive gear is rotatable in response to successive engagements by said resilient arm of said actuator; and
an indicator rotatably disposed in said indicator housing, wherein said indicator is rotatable in response to said rotation of said drive gear, said indicator comprising dosage indicia.

Abstract
A dispensing device for dispensing metered dosages of a medicament from a container includes a dispenser housing having a support block defining a longitudinal axis and an indicator housing disposed at least partially around the support block. An actuator includes a central, cylindrical hub portion adapted to be engaged by the container and centered about the longitudinal axis. The actuator is moveable along the longitudinal axis relative to the indicator housing and includes a resilient arm. A drive gear is rotatably disposed in the indicator housing and is rotatable in response to successive engagements by the resilient arm. An indicator is rotatably disposed in the indicator housing and is rotatable in response to the rotation of the drive gear. The indicator includes dosage indicia. A dispensing system and indicating device are also disclosed.
