Dispensing device
DCFirst Claim
1. A dispensing device for dispensing a medicament from a container, the dispensing device comprising:
- a dispenser housing comprising a support block having a well, said support block defining a longitudinal axis; and
an indicating device comprising;
a housing comprising a first annular wall radially spaced around said longitudinal axis and defining an interior cavity, said first annular wall having a viewing window formed therein;
a single indicator member rotatably mounted in said housing about said longitudinal axis, said single indicator member comprising a second annular wall radially spaced around said longitudinal axis wherein said single indicator member is nested in said interior cavity of said housing, said second annular wall having an outer circumferential surface visible through said viewing window and comprising dosage indicia adapted to indicate the number of dosages of medicament dispensed from or remaining in the container;
an actuator reciprocally moveable relative to said housing along said longitudinal axis; and
a drive mechanism intermittently engageable with said single indicator member, wherein said drive mechanism is operable to advance said single indicator member an incremental amount when said drive mechanism is engaged with said single indicator member, and wherein said single indicator member remains stationary and is free of engagement from said drive mechanism for at least some of said reciprocal movements of said actuator.

Abstract
An indicating device for indicating the number of dosages of medicament dispensed from a container includes a housing, a single indicator member nested the housing, an actuator and a drive mechanism. The drive mechanism is periodically engageable with the single indicator member. The drive mechanism is operable to advance the single indicator member an incremental amount when the drive mechanism is engaged with the single indicator member. The single indicator member remains stationary and is free of engagement from the drive mechanism for at least some reciprocal movements of the actuator. A dispensing device and a dispensing system are also provided.

9. A system device for dispensing a medicament from a container, the system comprising:
-
a dispenser housing comprising a support block having a well, said support block defining a longitudinal axis; a container disposed in said dispenser housing and comprising a valve stem received in said well of said support block, wherein said container is reciprocally moveable along said longitudinal axis relative to said dispenser housing; an indicating device disposed adjacent an end of said container, said indicator device comprising; a housing comprising a first annular wall radially spaced around said longitudinal axis and defining an interior cavity, said first annular wall having a viewing window formed therein; a single indicator member rotatably mounted in said housing about said longitudinal axis, said single indicator member comprising a second annular wall radially spaced around said longitudinal axis wherein said indicator is nested in said interior cavity of said housing, said second annular wall having an outer circumferential surface visible through said viewing window and comprising dosage indicia adapted to indicate the number of dosages of medicament dispensed from or remaining in the container; an actuator reciprocally moveable relative to said housing along said longitudinal axis in response to said reciprocal movements of said container relative to said dispenser housing; and a drive mechanism intermittently engageable with said single indicator member, wherein said drive mechanism is operable to advance said single indicator member an incremental amount when said drive mechanism is engaged with said single indicator member, and wherein said single indicator member remains stationary and is free of engagement from said drive mechanism for at least some of said reciprocal movements of said actuator. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
