  • Patent number: 5207348
    Abstract: An auxiliary paint brush bucket that has a planar front wall, an arcuate rear wall and a bottom wall to form an open top container. The front surface of the front wall has a plurality of conical shaped raised bumps thereon formed in a predetermined pattern so that a paint roller may be squeezed against the front wall surface to remove excess paint and it runs down the channels between the respective bumps. A unique pair of laterally spaced clips are formed on the top edge of the rear wall so that it can be removably installed along the inner surface of either a two gallon or five gallon paint bucket.
