Abstract

Abstract A dispensing pen includes a cylindrical body formed with a conically tapered forward end, with the forward end including a spherical or brush applicator. The cylindrical body includes an end cap threadedly mounted thereon, with the end cap housing a piston, with the piston biased within the cylindrical body to effect pressurizing of a fluid reservoir contained within the cylindrical body to direct such fluid through the applicator brush or spherical member of the applicator. The pressurizing piston mounted within the end cap includes a biasing means and a regulator to maintain pressurizing of the fluid, wherein alternatively, the piston includes a piston body that is externally threaded mounted within an internally threaded interior wall of the end cap to effect pressurizing of the reservoir.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 350 words
A correction fluid dispensing pan, comprising, a coaxially aligned cylindrical body, and a coaxially aligned end cap selectively securable to the cylindrical body at a rear terminal end of the cylindrical body, and the cylindrical body including a conically tapered forward end, and a forward cap securable to the forward end, wherein the forward cap defines a forward cap cavity, and the forward cap cavity is complementarily configured to the forward end of the cylindrical body, and the forward cap cavity includes a forward cap sealing ring mounted within the forward cap cavity orthogonally oriented relative to a forward cap axis, and the cylindrical body including a fluid reservoir contained coextensively throughout the cylindrical body containing an eradicator fluid therewithin, and a fluid conduit directing fluid from the cylindrical body through the forward end of the cylindrical body, and an applicator brush matrix mounted within the forward end of the cylindrical body, and a support tube contained within the fluid conduit securing a brush matrix therewithin, wherein the brush matrix extends forwardly of the forward end of the cylindrical body, and wherein the end cap includes a fluid piston, the fluid piston including a piston body, wherein the piston body is coaxially aligned relative to the fluid piston and extends within the end cap, and the piston body includes a piston sealing ring circumferentially mounted about the piston body, wherein the sealing ring is in frictional engagement with an interior surface of the cylindrical body to effect application of pressure to the eradicator fluid contained within the fluid reservoir, and wherein the piston body includes spaced toothed members defining a toothed side wall, and the end cap includes an end cap opening radially directed through the end cap, with the toothed side wall in confronting relationship relative to the end cap opening, and a pressure regulating rib projecting through the end cap opening in engagement with the toothed side wall, the pressure regulating rib orthogonally and integrally mounted to a support leg, the support leg mounted rearwardly of the end cap opening to an exterior surface of the end cap.
Claim 2
Dependent Claim 350 words
A correction fluid dispensing pan, comprising, a coaxially aligned cylindrical body, and a coaxially aligned end cap selectively securable to the cylindrical body at a rear terminal end of the cylindrical body, and the cylindrical body including a conically tapered forward end, and a forward cap securable to the forward end, wherein the forward cap defines a forward cap cavity, and the forward cap cavity is complementarily configured to the forward end of the cylindrical body, and the forward cap cavity includes a forward cap sealing ring mounted within the forward cap cavity orthogonally oriented relative to a forward cap axis, and the cylindrical body including a fluid reservoir contained coextensively throughout the cylindrical body containing an eradicator fluid therewithin, and a fluid conduit directing fluid from the cylindrical body through the forward end of the cylindrical body, and an applicator brush matrix mounted within the forward end of the cylindrical body, and a support tube contained within the fluid conduit securing a brush matrix therewithin, wherein the brush matrix extends forwardly of the forward end of the cylindrical body, and wherein the end cap includes a fluid piston, the fluid piston including a piston body, wherein the piston body is coaxially aligned relative to the fluid piston and extends within the end cap, and the piston body includes a piston sealing ring circumferentially mounted about the piston body, wherein the sealing ring is in frictional engagement with an interior surface of the cylindrical body to effect application of pressure to the eradicator fluid contained within the fluid reservoir, and wherein the piston body includes spaced toothed members defining a toothed side wall, and the end cap includes an end cap opening radially directed through the end cap, with the toothed side wall in confronting relationship relative to the end cap opening, and a pressure regulating rib projecting through the end cap opening in engagement with the toothed side wall, the pressure regulating rib orthogonally and integrally mounted to a support leg, the support leg mounted rearwardly of the end cap opening to an exterior surface of the end cap.
Claim 3
Dependent Claim 71 words
An apparatus as set forth in claim 1 wherein the end cap includes an end cap rear wall orthogonally oriented relative to an axis defined by the end cap, and the piston body includes a piston body rear end plate oriented parallel relative to the end cap rear wall, and a spring member captured between an interior surface of the end cap rear wall and the piston body rear end plate.
Claim 4
Dependent Claim 19 words
An apparatus as set forth in claim 2 wherein the end cap and the cylindrical body are coaxially aligned.
