Coated abrasives having a blend of abrasive particles and increased tear resistance

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.

Method of using a paint cup assembly

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.

Paint cup assembly with an extended ring

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.
