  • Patent number: 6622340
    Abstract: A paint tray that can be used in the vertical as well as horizontal position to hold paint for use with a roller. Formed longitudinally inside the tray is an inclined bottom surface designed to return excess paint to the basin when the paint tray is disposed horizontally. Formed on the inclined surfaces is a plurality of parallel raised contact surfaces that provides a directional contact surface used to remove excess paint from the roller and return the excess paint to the basin. The length of the inclined surface is sufficient to create freeboard for use in the vertical position without risk of spillage. The paint tray is equipped with a pair of legs attached to its distal end that allows the paint tray to rest vertically on the rung(s) of a ladder or step(s) of a stepladder, or horizontally on the ladder shelf as traditional paint trays. Aligned longitudinally on the distal end of the paint tray is a rigid handle for easy transport of the paint tray in the vertical position.
