Abstract

An inhaler includes a main body having a canister housing, a medicament canister retained in a central outlet port of the canister housing, and a dose counter having an actuation member for operation by movement of the medicament canister. The canister housing has an inner wall, and a first inner wall canister support formation extending inwardly from a main surface of the inner wall. The canister housing has a longitudinal axis X which passes through the center of the central outlet port. The first inner wall canister support formation, the actuation member, and the central outlet port lie in a common plane coincident with the longitudinal axis X such that the first inner wall canister support formation protects against unwanted actuation of the dose counter by reducing rocking of the medicament canister relative to the main body of the inhaler.

Abstract

A dose counter for a metered dose inhaler includes an incremental counting system for counting doses. The incremental counting system has a main body, an actuator arranged to be driven in response to canister motion and to drive an incremental output member in response to canister motion. The actuator and incremental output member are configured to have predetermined canister fire and count configurations in a canister fire sequence. The canister fire configuration is determined by a position of the actuator relative to a datum at which the canister fires medicament and the count configuration is determined by a position of the actuator relative to the datum at which the incremental count system makes an incremental count. The actuator is arranged to reach a position in the count configuration at or after a position in the canister fire configuration.
