Abstract:
In an adjustable brush cap apparatus having a fluid container, the fluid container defined by a container wall and a container floor, and the container including a housing cavity, and the housing cavity bounded at its lower end by the housing cavity floor, and the container including an externally threaded container conduit formed to an upper portion of the container wall with the upper portion spaced from the housing cavity floor, and including a cap assembly, the cap assembly including a cap assembly bottom floor with an internally threaded cap cavity coaxially directed into the cap assembly floor, the cap cavity threadedly securable to the externally threaded container conduit, and plunger means coaxially and reciprocatably mounted to the cap assembly, including a brush rod coaxially mounted to the plunger means, and a brush member mounted to a lower terminal end of the brush rod, wherein the brush assembly is arranged for extension from a first position, wherein the brush member is spaced from the housing cavity floor to a second position, wherein the brush member is in contact with the housing cavity floor, and wherein the cap assembly includes an upper cap bore coaxially aligned with the cap assembly and defined by a first diameter, and the cap bore in communication with a cap bore neck coaxially aligned with the cap bore and extending upwardly from the cap bore through a top wall of the cap assembly, wherein the cap bore neck is defined by a second diameter less than the first diameter, and the plunger means includes a cylindrical plunger body slidably mounted within the cap bore neck, and the plunger body including a cylindrical plunger shoulder defined by a third diameter less than the first diameter and greater than the second diameter to capture the plunger shoulder within the cap bore, and a spring member captured between a bottom surface of the plunger shoulder and a cap bore floor formed at a bottom terminal end of the cap bore, with the brush rod coaxially mounted medially of the spring, and wherein the brush member includes a bottom surface, wherein the bottom surface includes a central planar surface, a right arcuate surface and a left arcuate surface defining the bottom surface, and the brush member further including an arcuate right side and arcuate left side, and the brush member further defined by a convex outer surface and a convex inner surface directed between the arcuate right side and arcuate left side and the bottom surface, and wherein the cap assembly includes an externally threaded upper end and internally threaded cover cap coaxially aligned with the cap assembly securably and removably mounted to the threaded cap upper end, the improvement comprising:incorporating an annular sealing ring encircling an inside of the lower section of the cap, wherein said sealing ring is in intimate circumferential contact with brush stem wherein said annular sealing ring comprises a conically shaped cylindrical collar circumscribing said brush rod; a lowermost diameter sufficiently narrow to full insert and completely penetrate said externally threaded container conduit and enter said fluid chamber; an uppermost diameter sufficiently wide as to be prevented from inserting into the threaded container conduit such that as said cap assembly is threadingly engaged onto said bottle, said sealing ring is impinged against an inner surface of said conduit in such a manner as to form a seal there between such as to allow the fluid chamber to remain leak-proof, even under moderate pressure; and sealing means incorporated between said brush rod and an inner channel of said annular ring.
