1. A roller liquid compound applicator for applying a coating of a liquid compound to a target surface, wherein the applicator is configured to threadably attach to a liquid compound supply container having an externally threaded neck which defines and surrounds an external opening into the container, wherein the neck is configured to have a flat end as its distalmost surface and at least one of internal and external rims that deflect the surface of the flat end into respective internal and threaded external surfaces that form surfaces of the neck, wherein the roller liquid compound applicator comprises a U-shaped roller support frame comprising arms for support of a roller axle, a dispenser coupling cap and a drip guard attached to or integrated with the dispenser coupling cap, and a roller axle that is rotatably retained by arms of the roller support frame which provide an axis, and a liquid compound roller sleeve secured to or integrated with the roller axle and capable of rotating about the drip guard surface and the axis of the roller axle, wherein the roller support sleeve is positioned adjacent or contacting the drip guard;wherein the dispenser coupling cap comprises an internal threaded cavity that is defined by a cylindrical threaded surface for attaching the liquid compound supply container, an opening at one end that is continuous with the opening in the externally threaded neck of the attached liquid supply container, and an opposite base end comprising a flat annular base, an annular conical wall projecting from the base and an opening in the base surrounded by the conical wall to form a liquid flow path from the liquid supply container through the threaded cavity to a liquid reservoir within the cap;wherein the liquid reservoir is open to two or more flow ports that open into and are connected by a liquid compound distribution channel which is configured as a recessed channel in the drip guard upper surface such that the liquid compound can exit the flow ports into the liquid compound distribution channel and onto the roller sleeve, whereby the distribution channel and the drip guard act in concert to regulate the flow of the liquid compound and to evenly distribute the liquid compound over the liquid compound roller sleeve external surface for transfer onto the target surface; andwherein the conical wall projects from the base cap surface and is sized and configured to partially project into the opening of the neck of the attached liquid supply container and has an oblique surface, whereby the oblique surface bears and seals against the inner rim of the neck, and wherein the neck end may bear against an optional O-ring that is forced against the flat annular base of the roller liquid compound applicator between the conical wall and cylindrical threaded surface. 2. The roller liquid compound applicator of claim 1, wherein the roller support frame comprises a first L-shaped support frame arm attached to the dispenser coupling cap and a second L-shaped support frame arm attached to the dispenser coupling cap. 3. The roller liquid compound applicator of claim 2, wherein the liquid compound roller sleeve is disposed on a roller axle having a first end rotatably secured to the first support frame arm and a second end rotatably secured to the second support frame arm. 4. The roller liquid compound applicator of claim 1, wherein the drip guard comprises a concave surface that lies adjacent or touching the liquid compound roller sleeve and permitting rotation of the roller sleeve. 5. The roller liquid compound applicator of claim 1, wherein the dispenser coupling cap comprises a threaded cavity that is sized and configured for attachment to the liquid supply container. 6. The roller liquid compound applicator of claim 1, wherein the base end of the coupling cap comprises a flat annular base bounded by a conical wall an outward-facing bevel, wherein of the threaded neck of the liquid supply container engages the flat annular base via an O-ring and the beveled wall engages the inner rim of the threaded neck when the dispenser coupling cap is screwed onto the threaded neck of the liquid supply container and the rim contacts the beveled wall forming a liquid-tight searl. 7. The roller liquid compound applicator of claim 1, wherein the threaded cavity comprises, instead of a single annular conical wall, an annular groove having two concentric annular beveled walls, each having an oblique surface facing the other beveled wall, wherein the smaller diameter annular wall is an inner beveled wall and larger diameter annular wall is an outer beveled wall, wherein the walls are configured such that the beveled surfaces face toward each other and wherein the inner and outer rims of the neck of the liquid supply container respectively engage the inner beveled wall and the outer beveled wall when the dispenser coupling cap is screwed onto the threaded neck of the liquid supply container, thereby accommodating a circumference and wall thickness range of the neck end defined by the relative minimum and maximum diameters of the two annular beveled walls. 8. A roller liquid compound applicator for conveying a predetermined amount of a liquid compound from a liquid supply container to a target surface, wherein the liquid supply container comprises an inner surface capable of containing a liquid and a cylindrical externally threaded neck that opens into the container inner surface at one end and having a flat end as its distalmost surface and at least one of internal and external rims that deflect the surface of the flat end into respective internal and threaded external surfaces that form surfaces of the neck, whereby at least one of the internal or external rims threadably seals to the applicator at the other end, and wherein the roller liquid compound applicator comprises a dispenser coupling cap comprising an internal threaded cavity that is defined by a cylindrical threaded surface that threadably attaches to the liquid supply container and an internal flat annular base end of the threaded cavity that seals against the neck of the container when the dispenser coupling cap is screwed onto the threaded neck of the liquid supply container, wherein a liquid-tight seal is formed between the base end, which comprises an annular outwardly beveled wall projecting from the base end surface and configured so that the beveled surface of the wall mates with the inner rim of the threaded neck of the liquid supply container, wherein the inner rim is a surface deflection from the neck end of the liquid compound supply container into an internal surface of the container, wherein the neck end also may bear against an optional O-ring that is forced against the flat annular base end of the roller liquid compound applicator formed in the applicator between its conical wall and cylindrical threaded surface, andwherein the roller liquid compound applicator further comprisesa U-shaped roller support frame;a drip guard with a concave surface disposed on the dispenser coupling cap;a liquid compound roller sleeve secured to the roller support frame, wherein the roller sleeve has a convex surface and the liquid compound roller sleeve is partially enclosed by the drip guard concave surface;a liquid compound conveyance path that extends from the liquid supply container to the liquid compound roller sleeve, wherein the conveyance path comprises a liquid conduit that leads through the threaded cavity base end of the dispenser coupling cap from the liquid supply container and into a liquid reservoir;the liquid reservoir that holds a predetermined quantity of the liquid compound, wherein the reservoir is disposed between the base end of the dispenser coupling cap and at least two liquid compound flow ports;the liquid compound flow ports which extends from the liquid reservoir to within a liquid compound distribution channel recessed into the drip guard concave upper surface; andthe liquid compound distribution channel which provides a liquid flow path between the liquid compound flow ports, whereby the liquid compound distribution channel aids to evenly distribute and minimize dripping of the liquid compound received from the liquid compound flow ports between the drip guard concave upper surface and across the convex external surface of the roller liquid compound applicator. 9. The roller liquid compound applicator of claim 8, wherein the roller support frame comprises a first and a second L-shaped support frame arm, both of which are attached to the dispenser coupling cap. 10.
