Abstract

An actuator and corresponding base assembly, as well as related systems for applying a mark onto a surface. The actuator has at least one pair of wings which extend from the actuator body, wherein the entire lower edge of each wing curves continuously outwardly and upwardly from the body. The base assembly comprises a base surface at least partially disposed in a base plane and an opening therethrough, at least one wall extending upward from the base surface and defining two actuator-orienting guides, the guides being defined by substantially arcuate-shaped profiles substantially disposed in respective guide planes, the guide planes being disposed at an angle to one another of less than 180° and at an angle of less than 90° to the base plane, the guides being capable of contacting an actuator as it is received in the base assembly and disposed relative to one another such that they rotate an actuator into a seated position in the base. The system comprises an aerosol container having an actuator and a movable marking device comprising the base of the present invention. Another system allows an operator to vary the width of a mark from an initial dimension.
