Abstract:
A paint applicator comprising;a flexible walled paint container;an applicator head cap assembly threadably attachable to said paint container; anda transparent applicator head sealing cap threadably sealable over said applicator head assembly;said paint container having a paint reservoir therein and a neck opening defined by an exteriorly threaded neck portion having a top rim;said applicator head cap assembly including:a head cap member having an internally threaded bottom portion companionately threaded to thread onto said exteriorly threaded neck portion of said paint container, said internally threaded bottom portion having an integral top wall that contacts said top rim of said neck portion and substantially blocks said neck opening when said head cap member is threaded onto said neck portion,an externally threaded portion,a horizontally oriented, semi-cylindrical roller cavity formed in a head cap member top surface, the bottom portion of said roller cavity having a continuous opening across the length thereofa one-way valve positioning cavity within said head cap member in connection with said roller cavity, the top wall of said internally threaded bottom portion of said head cap member forming the bottom wall of said one-way valve positioning cavity, the upper portion of the positioning cavity being coextensive with the continuous opening of the bottom portion of the roller cavity for continuous, unobstructed flow therebetween;a paint passageway formed in said top wall of said internally threaded bottom portion of said head cap assembly to form a fluid pathway from said paint reservoir into said one-way valve positioning cavity when said head cap member is threaded fully onto said exteriorly threaded neck portion of said paint container;a resilient duck bill one-way valve installed within said one-way valve positioning cavity and on top of said bottom wall thereof in a manner to allow paint flow from said paint reservoir, through said one-way valve positioning cavity, and into said roller cavity, and prevent back flow of paint from said roller cavity into said paint reservoir; anda cylinder-shaped paint applicator roller member rotatably entrapped within said roller cavity having greater than fifty percent of the volume thereof positioned within said roller cavity and a remaining portion thereof extending past said head cap member top surface;said transparent applicator head sealing cap having an internally threaded bottom portion companionately threaded to thread onto said externally threaded portion of said head cap member and an internal cavity sized and shaped such that an internal top surface defining said top of said internal cavity is in contact with said paint applicator roller member when said transparent applicator head sealing cap is fully threaded onto said externally threaded portion of said head cap member;said paint container having sidewalls sufficiently flexible to allow a compression force to be developed by squeezing to force paint within said paint reservoir through said duck bill one-way valve into said roller cavity.
