A dispensing container for application of a fluid film forming substance to a surface, particularly a therapeutic film to a users skin comprising a reservoir of a fluid film forming substance, a dispensing nozzle for the film forming substance, and a pump to send the substance from the reservoir through the dispensing nozzle. The dispensing nozzle comprises an elongate slot shaped aperture, and the dispensing container is adapted, particularly by a support extending from the side of the dispenser, so the nozzle can move adjacent to the surface in a direction transverse to the length direction of the slot whilst the substance is flowing through the aperture.
