Abstract
An improved paint cup for a suction feed hand held spray gun having a jar and a removable cap. A resilient unitary molded check valve either is positioned within or is positioned to cover a vent opening extending through the cap to allow exterior air to flow into the jar while inhibiting paint flow from the jar through the vent opening when the spray gun is tilted.
