Long distance marking devices and related method

A device for propelling a non-aerosolized liquid stream to long distances comprising

• a container,
• a liquid residing within said container comprising water, a surfactant, a polymer, a pigment, and a coalescing solvent, said polymer being selected from the group consisting of poly (vinyl acetate), acrylics, vinyl acrylics, and mixtures thereof,
• a propellant residing within said container which remains gaseous when subjected to pressure within said container and which discharges said liquid from said container, said propellant being a member selected from the group consisting of nitrogen, carbon dioxide, nitrous oxide, argon, helium, and mixtures thereof,
• valve means comprising an inlet and an outlet for controlling the discharge of said liquid from said container, said valve means being biased in a closed position and being movable to an open position in response to external pressure thereto, wherein the inlet of said valve means is in communication with said container such that said liquid can flow from said container through said valve means, and
• an actuator in communication with the outlet of said valve means such that said liquid can flow from the outlet of said valve means through said actuator and outwardly from said device, said actuator comprising a cylindrical tube having a length and an outlet at one end of said tube, wherein the inside diameter of said tube remains constant along its length and is equal to the diameter of the tube outlet from which the liquid exits the device,
• wherein the combination of said valve means, said actuator, and said propellant cooperate to discharge said liquid from said container as a non-aerosolized liquid stream to a distance of from about ten to about twenty-five feet when said valve means is moved into the open position.
