Abstract: The adapter is useful in providing overhead gravity feed of paint to a conventional air spray paint gun having a bottom paint inlet port. The adapter includes a paint receptacle with a closable top lid and a bottom outlet. The receptacle can be transparent and bear volume indicia so that the amount of paint left in the receptacle can be estimated as spraying proceeds. The receptacle lid can be hinged and bear a releasable latch plate. The adapter also includes a conduit, the upper end of which is releasably connected to the receptacle at the outlet. The conduit depends from the receptacle and is adapted to support it in the upright position directly above an air spray paint gun.
