  • Liquid herbicide applicator
    Patent number: 8418400
    Abstract: A liquid herbicide applicator includes a length adjustable handle member and a reservoir removably coupled to the handle member, the reservoir defining an inlet for receiving a liquid and an outlet from which to dispense liquid. The applicator includes a valve assembly coupled to the reservoir outlet operative between an open configuration that allows the liquid to flow through the outlet and a closed configuration that prevents the liquid from flowing through the outlet. The valve assembly is biased toward the closed configuration. A dispenser assembly having a cap portion is operatively coupled to the valve assembly and includes an application portion connected to the cap portion, the cap portion being selectively movable closer to the valve assembly so as to urge the valve assembly to the open configuration and away from the valve assembly so to allow the valve assembly to return to the closed configuration.
