Abstract
Abstract There is provided an applicator adapted to be employed in removable and communicating relationship with an uprightable hand-manipulatable container of pressurized fluid, such as liquid masking tape, paints, etc., whereby the fluid bands or stripes can be controllably applied from the applicator fore-terminus to upright window panels and other broad working surfaces. The applicator includes a housing extending longitudinally forwardly along a main-axis that intersects the container lengthwise axis, the housing forwardly terminating as an annular lead-end defining a lead-plane which transversely intersects the main-axis; a porous pad firmly abutting the housing lead-end and preferably removably attached to the housing provides the applicator foreterminus. There is a regulatable tubular conduit means extending from its inlet-end (which is transversely offset toward a fluids container) to an outlet-end located slightly rearwardly of the lead-plane and in fluid delivery relationship to the porous pad.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
258 words
An applicator for fluid adapted to be employed in removable and communicating relationship with an uprightable container for pressurizeable fluids whereby the fluid can be forced upwardly along the container lengthwise vertical-axis and expelled through the container upper discharge spout toward the fluid applicator, said fluid applicator being adapted to controllably apply fluid bands upon working surfaces located laterally offset from the container vertical-axis, said fluid applicator comprising: A. A housing extending longitudinally along a substantially horizontal main-axis and including a leading head portion forwardly terminating as an annular polygonal lead-end defining a lead-plane that transversely intersects said main-axis, said housing head portion including a generally transversely extending frontal-wall provided with a bore along said mainaxis, the frontal-wall having a front-side being defined by a plurality of rearwardly convergent triangular planar faces each having an apex at the frontal-wall bore; B. A tubular conduit means attached to the housing and including an outlet-end communicating with the bore of the housing frontal-wall and rearwardly of said lead-plane, said tubular conduit means also including an inlet-end downwardly transversely offset from the main-axis and adapted to be attached in communicating relationship with the discharge spout of an underlying upright container reservoir of fluid, the said tubular conduit means including an elongate leading portion extending parallel to said main-axis; and C. A porous pad attached to the housing head portion and providing a fore-terminus for the applicator, said porous pad being located at the housing lead-end so as to lie along said lead-plane thereby being forwardly offset from the conduit means outlet-end.
Claim 2
Dependent Claim
258 words
An applicator for fluid adapted to be employed in removable and communicating relationship with an uprightable container for pressurizeable fluids whereby the fluid can be forced upwardly along the container lengthwise vertical-axis and expelled through the container upper discharge spout toward the fluid applicator, said fluid applicator being adapted to controllably apply fluid bands upon working surfaces located laterally offset from the container vertical-axis, said fluid applicator comprising: A. A housing extending longitudinally along a substantially horizontal main-axis and including a leading head portion forwardly terminating as an annular polygonal lead-end defining a lead-plane that transversely intersects said main-axis, said housing head portion including a generally transversely extending frontal-wall provided with a bore along said mainaxis, the frontal-wall having a front-side being defined by a plurality of rearwardly convergent triangular planar faces each having an apex at the frontal-wall bore; B. A tubular conduit means attached to the housing and including an outlet-end communicating with the bore of the housing frontal-wall and rearwardly of said lead-plane, said tubular conduit means also including an inlet-end downwardly transversely offset from the main-axis and adapted to be attached in communicating relationship with the discharge spout of an underlying upright container reservoir of fluid, the said tubular conduit means including an elongate leading portion extending parallel to said main-axis; and C. A porous pad attached to the housing head portion and providing a fore-terminus for the applicator, said porous pad being located at the housing lead-end so as to lie along said lead-plane thereby being forwardly offset from the conduit means outlet-end.
Claim 3
Dependent Claim
50 words
The fluids applicator of claim 1 wherein at least two sides of the housing polygonal lead-end intersect at an acute angle; and wherein the applicator fore-terminus is defined by a fluid-absorbent fabric pad removably attached to the housing lead-end, said pad being Substantially planar and perpendicular to the housing main-axis.
Claim 4
Dependent Claim
70 words
The fluids applicator of claim 2 wherein the housing annular lead-end is of symmetrical polygonal shape; wherein the frontal-wall front-side comprises a plurality of rearwardly convergent planar faces of substantially isosceles triangular shape; wherein said frontal-wall includes a tubular nipple extending rearwardly therefrom along said main-axis; and wherein the conduit means elongate tubular leading portion is removably frictionally engaged with said nipple and extends rearwardly therefrom along the housing main-axis.
Claim 5
Dependent Claim
100 words
The fluids applicator of claim 1 wherein the housing head portion is provided with a shank commencing at said lead-end and extending rearwardly therefrom for a finite-length, said shank surrounding the main-axis and having therealong a regular cross-sectional shape of a finite-area; and wherein the porous fabric pad has an area exceeding said shank finite-area whereby the periphery of said pad is adapted to extend rearwardly of the lead-end and to lie along said shank, the porous pad at said peripheral portion being removably securely interposed between the said shank and a frictionally engaged removable collar that surrounds said shank.
Claim 6
Dependent Claim
74 words
The fluids applicator of claim 4 wherein the housing shank including the annular lead-end and the collar internal side are of like symmetrical polygonal shape, the housing head portion at the shank rearward end including an abrupt annular shoulder of said symmetrical polygonal shape, the removable annular collar abutting the abrupt shoulder and being of like dimension therewith whereby the housing immediately rearwardly of said shoulder merges at constant elevation with the removable collar.
Claim 7
Dependent Claim
58 words
The fluids applicator of claim 5 wherein the housing includes a substantially horizontal floor-panel located below the main-axis and extending longitudinally rearwardly from the abrupt annular shoulder, said floor-panel remotely rearwardly of the housing lead-end being provided with a vertical opening, said conduit means trailing portion extending upwardly from its inlet-end through the floor-panel rearwardly disposed vertical opening.
Claim 8
Dependent Claim
93 words
The fluids applicator of claim 1 wherein the housing annular lead-end is of regular tetragonal shape; wherein the frontal-wall front-side comprises four rearwardly convergent planar faces each of substantially isosceles triangular shape; wherein the conduit means elongate tubular leading portion is removably engaged with the frontal-wall at the bore and extends rearwardly therefrom along the main-axis; wherein the housing includes a floor-panel provided with a vertical opening located remotely rearwardly of the housing lead-end; and wherein the conduit means trailing portion extends upwardly from its inlet-end through the floor-panel rearwardly disposed vertical opening.
Claim 9
Dependent Claim
