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.
