Abstract: In a method for the relative orientation of the spray-discharge valve actuator and actuator nozzle of a container with respect to a protective cover which is designed to operate the valve actuator, the cover is brought closer to the actuator in coaxial relation thereto, the cover and actuator are brought into the desired relative orientation with friction between a radial lug carried by the actuator and a helical ramp carried by the cover and inclined at an angle of slope of at least 45.degree. with respect to the axis. The cover is then brought in a movement of axial displacement to a position of operation of the actuator on the container.
