Abstract
Abstract A fluid applicator has a fluid absorbant dispensing roller mounted by an applicator head having inlet means for releasably connecting the roller in fluid communication with a disposable fluid storage container and fluid pressure responsive valve means in the applicator head for restricting fluid flow to the roller normally whereby the roller is applied with fluid by manually squeezing the container.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
186 words
A fluid applicator having a fluid absorbant dispensing roller and a squeezable, disposable fluid storage container comprising: an applicator head having means for rotably mounting said roller; inlet means on said head for releasably connecting said container to said head; fluid passage means in said applicator head for communicating fluid from said inlet means to said roller; fluid pressure responsive valve means in said fluid passage means for restricting fluid flow to said roller whereby said roller may be supplied with fluid by manually squeezing said container, wherein said valve means comprises: a hollow cone of flexible plastic material having a pin hole at the apex thereof, said cone opening toward said container with the apex end pointing downstream of said fluid passage means, said pin hole being of a predetermined size to permit fluid flow therethrough normally only in response to pressurizing of fluid upstream of said cone as by said squeezing of said container; and an extensible handle means on said container wherein said handle means comprises: a split cylinder of resilient material slip fitted snugly about said container and manually slidable relative thereto.

A fluid applicator having a fluid absorbant dispensing roller and a squeezable, disposable fluid storage container comprising: an applicator head having means for rotably mounting said roller; inlet means on said head for releasably connecting said container to said head; fluid passage means in said applicator head for communicating fluid from said inlet means to said roller; fluid pressure responsive valve means in said fluid passage means for restricting fluid flow to said roller whereby said roller may be supplied with fluid by manually squeezing said container, wherein said valve means comprises: a hollow cone of flexible plastic material having a pin hole at the apex thereof, said cone opening toward said container with the apex end pointing downstream of said fluid passage means, said pin hole being of a predetermined size to permit fluid flow therethrough normally only in response to pressurizing of fluid upstream of said cone as by said squeezing of said container; and an extensible handle means on said container wherein said handle means comprises: a split cylinder of resilient material slip fitted snugly about said container and manually slidable relative thereto.
Claim 3
Dependent Claim
197 words
A fluid applicator having a fluid absorbant dispensing roller and a disposable, squeezable fluid storage container comprising: an applicator head having a plurality of fluid dispensing ports in a generally linear array and roller mounting means for mounting said roller adjacent and aligned to said ports; manifold means within said head in fluid communication with each of said ports; fluid inlet means in said head releasably connectable with said container for receiving fluid from said container into said head; fluid pressure responsive valve means in said head adjacent said inlet means for normally preventing fluid flow therethrough but allowing same under fluid pressure developed by manually squeezing said container; fluid passage means in said head for communicating fluid from said valve means to said manifold means, wherein said roller mounting means comprise a pair of resiliently bendable spaced arms formed integrally of said head whereby said roller may be assembled or disassembled through manual spreading of said arms; and wherein said fluid dispensing ports are positioned symetrically about a center line through said applicator head and are spaced from each other in increasingly greater spacings between successive ports as the ports progress outwardly of said center line.
