Claims for Patent: 6,435,372

Title: Delivery system for a medicament and method for the assembly thereof
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.
