  • Patent number: 7874755
    Abstract: A frustoconically-shaped paint roller (210) to selectively apply paint to surfaces and surface corners. The paint roller has a rolling guide (280) that permits the roller to rotate eccentrically so as to accommodate rough or uneven surfaces. A circular integral guard (260) of predetermined diameter is present to prevent the user from applying excessive force when using the roller and squeezing paint from the roller. When used correctly, the integral guard does not contact the surface to be painted. One embodiment of the invention has a chamber (270) to store paint so that the repeated frequent charging of the roller with paint from a can or tray is avoided.
