Indicating device
First Claim
1. An indicating device for a dispenser that dispenses metered dosages of a substance from a container having a valve moveable between a closed position and an open position, said container dispensing said metered dosage when said valve is moved to the open position, said indicating device comprising:
- a housing comprising at least one engagement member;
a plurality of indicator members coaxially mounted in said housing and comprising at least a first and second indicator member, at least one of said first and second indicator members having dosage indicia, at least one of said first and second indicator members comprising an advancement member and at least the other of said first and second indicator members comprising a plurality of teeth, wherein said engagement member is selectively engaged with said advancement member, wherein said engagement member biases said advancement member into operable engagement with at least one of said plurality of teeth of said at least the other of said first and second indicator members as said first indicator member is rotated relative to said second indicator member, whereby said advancement member causes said second indicator member to rotate an incremental amount.

Abstract
An indicating device for use with a dispensing device that dispenses metered dosages of a medicament from a container having a valve moveable between an open and closed position. In a preferred embodiment, the container is reciprocally moveable within the housing along a longitudinal axis. The housing preferably has a well adapted to receive a valve stem and an exhaust port. The well communicates with the port such that the metered dosage of medicament is dispensed through the port when the valve is moved to the open position. An indicator assembly comprises an indicator member that includes dosage indicia visible to a user. In a preferred embodiment, the indicator assembly is provided in an indicator module. A method for dispensing measured dosages is also provided, along with a kit capable of being assembled as an inhalation device. A delivery system having a key member and a key entry passageway is also provided.
