This application discloses a dose counter device of the type for use on an aerosol dispensing assembly having an aerosol container and an actuator. The dose counter device is used for indicating the release of a dose of aerosol medication caused by the application of a force, in an axial direction, on the aerosol dispensing assembly. The dose counter device has a cap, a slider and a first counter ring. The cap is moved in a first direction along an axis of the container, which causes movement of the slider in a first linear direction laterally, relative to the axis of the container, as a function of the movement of the cap in the first direction. The first counter ring is rotated through a first arc in a first circumferential direction about the axis of the container, as a function of the movement of the slider in the first linear direction. The cap is then moved in a second opposite direction, which causes the slider to move in a second opposite linear direction, which in turn causes rotation of the first counter ring through a second arc in the first circumferential direction about the axis of the container. A sum of the first and second arcs of movement of the first counter ring defines a circumferential extent of movement of the first counter ring relative to the cap that indicates a single dose of aerosol medication dispensed from the container.Linvention concerne un dispositif de compteur de doses du type à utiliser sur un ensemble de distribution daérosol comprenant un réservoir daérosol et un actionneur. Le dispositif de compteur de doses est utilisé pour indiquer la libération dune dose dun médicament en aérosol provoquée par lapplication dune force, dans une direction axiale, sur lensemble de distribution daérosol. Le dispositif de compteur de doses comprend un couvercle, un curseur et un premier anneau de compteur. Le couvercle est enlevé dans une première direction le long dun axe du réservoir, ce qui entraîne le déplacement du curseur latéralement dans
