Abstract: A paint cup assembly for a paint sprayer is disclosed and includes a cap, a paint reservoir formed with an air inlet port, and a valve assembly disposed within the paint reservoir and engaged with the air inlet, wherein the valve assembly is configured to be operable from a closed configuration, in which air flow through the air inlet port is prevented, and an open configuration, in which air flow through the air inlet port is permitted, upon actuation of a spray gun.

Abstract: A paint cup assembly for a paint sprayer is disclosed and can include a paint reservoir assembly. The paint reservoir assembly can include a paint reservoir and a cap configured to engage the paint reservoir. The paint reservoir assembly further includes a structural element for engaging a paint spray gun to form a tactile feedback mechanism. The tactile feedback mechanism can provide a tactile indication to a user as the paint reservoir assembly is engaged with the paint spray gun.

Abstract: A method of using a paint cup assembly with a paint sprayer includes filling a paint cup assembly with paint, closing the paint cup assembly, inverting the paint cup assembly, and engaging the paint cup assembly with the paint sprayer. The paint cup assembly includes a spring loaded valve to prevent paint from leaking from the paint cup assembly when the paint cup assembly is inverted.

Abstract: A paint cup assembly for a paint sprayer is disclosed and can include a cap, a paint liner defining a closed proximal end and an open distal end, and a ring configured to fit around the paint liner. The ring can engage the cap and secure the paint liner to the cap. Further, the ring can include an axial extension that can extend toward the proximal end of the paint liner such that the ring can be configured to allow a user to grasp the paint cup assembly without collapsing the paint liner during attachment with a paint sprayer.

Abstract: A paint cup assembly for a paint sprayer is disclosed and can include a paint reservoir, a cap configured to engage the paint reservoir, and a valve assembly disposed within the cap. The cap can include an outlet and the valve assembly can be operable from a closed configuration in which fluid flow through the outlet is prevented to an open configuration in which fluid flow through the outlet is permitted upon engagement with a paint sprayer.

Abstract: An abrasive disc includes a backing layer on a first major surface, a water-impermeable abrasive layer on a second major surface, and a water-absorbable, compressible, resilient, porous foam layer sandwiched in between the backing layer and the abrasive layer. The disc further includes a plurality of perforations. The disc is used to abrade a surface. Fluid is absorbed into the abrasive disc. The fluid is then released to the surface by compressing the abrasive disc against the surface in an abrading motion. The fluid is allowed to mix with and absorb surface swarf; and compression on the abrasive disc is released, reabsorbing the fluid and trapping swarf inside the disc.

Abstract: A paint cup assembly filling station includes an upper paint cup tray formed with at least one upper hole configured to receive a paint cup assembly, a lower paint cup tray formed with at least one lower hole configured to receive a paint cup assembly, and a housing separating the upper paint cup tray from the lower paint cup tray.

Abstract: A paint cup assembly for a paint sprayer is disclosed and includes a cap and a paint liner configured to engage cap. The paint liner includes a hollow body having a proximal end and a distal end. The proximal end is closed and the distal end is open. Further, the paint liner comprises a plurality of indicia spaced apart along a length of the paint liner and each of the indicia represent an incremental change in an internal volume of the paint liner.

Abstract: A paint cup assembly for a paint sprayer can include a cap formed with an external rim and a plurality of threads adjacent to the external rim and a paint reservoir configured to engage the cap. The paint reservoir can include a distal end formed with a hub having threads configured to engage the threads on the cap. Moreover, a seal can be disposed between the external rim of the cap and the distal end of the paint reservoir. The seal can be compressed between the external rim of the cap and the distal end of the paint reservoir as the paint reservoir is threaded around the cap. Further, the seal can prevent air infiltration into the paint reservoir as paint is withdrawn from the paint reservoir by a spray gun.

Abstract: A masking dispenser includes a vertical support, a paper roll, a fixture, and a reel. The paper roll support extends horizontally to the vertical support. The fixture includes a bracket coupled to an extension. The bracket is secured to the vertical support and the extension extends in a direction perpendicular to the paper roll support. The reel is rotatably coupled to the extension and is configured to receive a roll of masking tape and to dispense the masking tape parallel to an edge of a masking paper roll located on the paper roll support.
