Abstract: A tray for coating fluids and paints for use with a roller comprising a deep well section, a gradually-sloped section, a brush rest section, tray legs extending downward along a slanted vertical line, horizontal extensions at the bottom of said tray legs, substantially vertical walls terminating in a wall lip at a uniform height, said tray being characterized by an underside which is generally complementary to the configuration of the top side, said tray being stabilized by a plurality of ribs extending generally longitudinally of said tray beneath the brush rest section, whereby a plurality of said trays may be nested within each other when not in use, and being further characterized by an excellent rigidity of structure and minimal deformation when said tray is in use and filed with a coating fluid.
