Abstract
An indicating device suitable for indicating the number of metered dosages that have been dispensed from or remain in a container including a base member, a cap member moveably connected to the base member, an indicator member rotatably mounted to one of the cap member and base member and a drive member. The indicator member comprises a first stop member, and the drive member comprises a second stop member. The first stop member engages the second stop member as the indicator is moved to the final position. The engagement between the first and second stop members prevents the drive member from being rotated about the second axis. In another preferred embodiment, an inhalation device for dispensing metered dosages of medicaments from a container includes a container having a predetermined number of metered doses and the indicating device. A method for indicating the number of metered dosages of medicaments dispensed from or remaining in the container is also provided.
