摘要：
It has proven difficult to provide dispensers with dose counters that reliably “count” the release of medicament doses from containers. It is highly undesirable for any movements to not be counted since this will lead to the counter indicating a higher number of doses remaining than is actually the case, typically this problem is caused by parts in the counter mechanism and its connection with the dispenser mechanism. In one or more aspects a dispenser for dispensing a dose of a gaseous, gas borne or droplet substance from a substance source is provided, in particular dispensers which attempt to address the above stated problem by including a bistable portion being biased into position and accounting for the difference in position of the top of the dispenser cap that it closes； or at least provide the public with a useful choice. The dispenser for dispensing a dose of a gaseous, gas borne or droplet substance from a substance source comprising: a body for receiving a substance source, the body having a mouthpiece； a junction member slideably arranged in the body for movement in a longitudinal axis of the body to release a dose of a substance from a substance source, the junction member comprising a socket for receiving a spout of a substance source； a dispenser driver for moving the junction member in the longitudinal axis of the body to release a dose of a substance from a substance source, the dispenser driver comprising a pivot shaft and a cam arranged on the shaft, the dispenser driver being arranged within the body such that rotation of the pivot shaft causes the cam to rotate and apply a force to the junction member so as to move the junction member in the longitudinal axis； a cam follower slideably arranged within the body, the cam follower comprising a base and a substantially rigid protrusion extending from the base, the protrusion being arranged between the dispenser driver and the junction member such that a force applied by the cam of the dispenser drive
