Abstract

The present invention contemplates a fluid applicator useful for applying a fluid in a uniform and discrete manner to a remote surface wherein said applicator has a fibrous pad which is saturated and retains the fluid until applied to a surface, a valve or throttle means to control the amount of fluid in the fibrous pad and a telescoping handle element which can be extended to provide an elongate handle for reaching remote areas and to expose a cylindrical fluid vessel having a flexible wall which is compressed to extrude fluid therefrom and into the fibrous pad.

Claims

1. A fluid applicator comprising a tubular vessel having first and second ends, an elongate axis and a wall extending between said first and second ends, wherein said first end further comprises a port through which a fluid may pass from the interior of said tubular vessel;

said wall having a smooth exterior surface sufficiently flexible to allow the volume of said tubular vessel to be decreased by the application of an external force to said wall to cause the fluid located in said tubular vessel to be extruded through said port, and said wall being biased to return to a position having a substantially circular cross section when said force is removed;

further comprising a tubular sleeve having an elongate axis and first and second ends, which axis is substantially concentric with the elongate axis of said tubular vessel, wherein the inner diameter of said tubular sleeve is sized to slidably engage with the outer diameter of said wall of said tubular vessel and said tubular sleeve is mounted about said tubular vessel in a first position, wherein said tubular sleeve'"'"'s first end is proximate said tubular vessel'"'"'s first end and said tubular sleeve'"'"'s second end is proximate said tubular vessel'"'"'s second end, and has a second position wherein said tubular sleeve'"'"'s first end is proximate said tubular vessel'"'"'s second end and said tubular sleeve'"'"'s second end is extended from said tubular vessel'"'"'s second end; and

the tubular vessel being tapered with the diameter of the tubular vessel larger at its second end than at its first end, and the tubular sleeve being tapered with the diameter of the tubular sleeve larger at its second end than at its first end, with the exterior diameter of the second end of said tubular vessel larger than the internal diameter of the first end of the tubular sleeve so that the first end of the tubular sleeve is prohibited from passing over the second end of the tubular vessel to avoid disengagement of the tubular sleeve from the tubular vessel, and so that the tubular sleeve can be frictionally wedged against the tubular vessel with the first end of the tubular sleeve proximate the second end of the tubular vessel to secure the said tubular sleeve in an extended position.

2. The fluid applicator of claim 1 wherein said tubular sleeve is sufficiently rigid to prohibit said tubular vessel'"'"'s flexible wall from being deformed when said tubular sleeve is in its first position.

3. The fluid applicator of claim 1 wherein said tubular sleeve has an elongate cutout to allow access to said tubular vessel'"'"'s flexible wall when said tubular sleeve is in its first position, permitting said tubular vessel'"'"'s flexible wall to be deformed by the application of pressure thereto through said elongate cutout.

4. The fluid applicator of claim 1 wherein said tubular vessel has a cap assembly attached to its first end, wherein said tubular vessel and cap assembly are sized so as to prohibit the passage of said tubular sleeve from its first position to a position where said tubular sleeve'"'"'s first end is located over said cap.
