Abstract
A spray or injection device that includes a casing or a pusher that includes at least one tab radially moveable between a first radial position, in which the tab does not impede the movement of the pusher with respect to the casing, and a second radial position in which the tab opposes movement of the pusher. The pusher or the casing, respectively, includes at least one ramp-shaped projection configured to bring the tab into the second radial position and then allow it to return to the first radial position. The pusher or the casing further includes at least one stop between the pusher and casing to delineate the end of a first stroke corresponding to a first dose of medicament, and the beginning of a second stroke corresponding to a second dose of medicament.
