Abstract
A dose counter attached or attachable to the base of a pressurised canister for a metered dose inhaler and comprising a spring-loaded cap (14) which may be depressed in relation to a second part (1) mounted on the domed base of the canister (C). Within the cap (14) is a pair of independently rotatable rings, each carrying on its upper surface indicia visible through a window (13) in the cap. For each depression of the cap (14) relative to the canister, the first ring (4) is indexed in rotation, and for each complete revolution of the first ring (4), the second ring (8) is indexed in rotation. The first ring (4) carries the numbers 0 to 9 and the second ring (8) carries the numbers 00 to 20 so that the device counts down progressively from 200 to 000 thus providing an incremental indication of the number of doses remaining in the canister.
