<p>An actuator (70) and corresponding base assembly, as well as a system for applying a mark onto a surface which incorporates such components. The actuator (70) has upper and lower ends and a passage therethrough which terminates in an orifice (76) through which material travels upon discharge from the container (20), the orifice (76) located at the lower end of the actuator (70), comprising an actuator body having an axis (A-A) which passes through the upper and lower ends thereof, and at least one pair of wings (74,75) which extend from the actuator body, each wing having a lower edge (77,78), the lower edge curving continuously outwardly and upwardly from the body. The base assembly comprises, in combination, a base surface at least partially disposed in a base plane and having an opening (41), the contents of the aerosol container (20) being dischargeable through the orifice (76) and the opening when the aerosol container actuator is seated within the base assembly, at least one wall (97,48) extending upward from the base surface and defining two actuator-orienting guides (43,44) , the guides being defined by substantially arcuate-shaped profiles substantially disposed in respective guide planes, the guide planes (43,44) being disposed at an angle to one another of less than 180 DEG and at an angle of less than 90 DEG to the base plane, the guides (43,44) being capable of contacting the actuator as it is received in the base assembly, the guides being disposed relative to one another such that they rotate the actuator (70) to guide the actuator into the seated position. The system comprises an aerosol container (20) having an actuator (70) which effects the discharge of marking material from the container (20), advantageously the aforesaid actuator of the present invention, and a movable marking device (10) comprising the base of the present invention. Another system is also provided by the present invention which allows for an operator to vary the width of a mark from its initial dimension. <IMAGE></p> |
