ABSTRACT:
A pen-like dispenser for applying rust converting liquid including a cap having an outer abrading surface adapted to scrape loose paint and rust from a surface to which the liquid is to be applied; and a liquid dispensing part including an elongate fluid reservoir having resiliently flexible walls, and a dispensing tip assembly. The tip assembly includes a valve member normally closing the tip assembly and having a tip projecting through an outlet passageway through the housing under the influence of a spring. The valve member may be moved to an open position by pressing its tip against a rusted substrate to afford outflow of the liquid, which flow can be controlled and aided by pressing inwardly on the flexible walls of the reservoir.
