Abstract
A tensioning arrangement for an aerosol dispenser is presented where the tensioning arrangement has a conveying tube; an elastic member arranged to store mechanical energy from a substantially axial tensioning movement of the conveying tube; a rotatable member; a transmission mechanism configured to transmit a tensioning rotation of the rotatable member to the tensioning movement of the conveying tube, wherein the transmission mechanism has a cam profile and a cam follower arranged to follow the cam profile, wherein the cam profile has at least one priming structure; and wherein the tensioning arrangement is configured such that the conveying tube makes a temporary priming movement towards an initial position when the cam follower passes each priming structure during the tensioning movement of the conveying tube by means of the tensioning rotation of the rotatable member. An aerosol dispenser is also provided.
