  • Patent number: 4875781
    Abstract: A paint container is set forth wherein internal mixing of paint is effected by an oscillation of the paint can by means of the associated bail or handle pivotally secured thereon. A plurality of diametrically opposed arcuate vanes are integrally secured opposed to one another to an interior surface wall of a paint container. The vanes are of a height less than that of the internal shape defined by a radius equal to that of said paint container. The vanes are formed with a matrix of apertures therethrough to enhance the flow and turbulence of the paint within the container to effect the mixing of the paint.
