Apparatus and method for mixing a fluid dispersion disposed in a container having either a cylindrical or a square shape. The apparatus includes a holding structure having a retaining structure connected to a base. The retaining structure prevents lateral movement of the container both when the container has a cylindrical shape and when the container has a generally square shape with a width substantially equal to the diameter of the cylindrical shape. The apparatus rotates the container about at least one axis.

1. Apparatus for mixing paint, said apparatus comprising:(a) a mixing device comprising:a holding structure having a retainer extending from a base, said retainer including a plurality of interior surfaces at least partially defining an interior holding space having a substantially rectangular cross-section, said interior surfaces including a pair of parallel and substantially planar first surfaces and a pair of parallel and substantially planar second surfaces;a mounting support to which the holding structure is secured; andan electric motor connected to the mounting support for rotating the mounting support and the holding structure about at least one axis; and(b) a plastic container removably disposed in the interior holding space of the holding structure, said container comprising a body defining an interior volume for holding the paint, said body having a plurality of side walls joined at rounded corners to provide said body with a substantially rectangular cross-section. 2. The apparatus of claim 1, wherein the holding space of the retainer has a substantially square cross-section. 3. The apparatus of claim 1, wherein the at least one axis comprises a vertical first axis and a second axis that is non-perpendicular to the first axis. 4. The apparatus of claim 1, wherein the interior holding space is sized to snugly receive a conventional 1 gallon paint container. 5. The apparatus of claim 4, wherein the plastic container has a width between side walls that is substantially the same as the diameter of a conventional 1 gallon paint container. 6. The apparatus of claim 1, wherein the holding structure further comprises a base having a plurality of upwardly extending structures disposed around a floor. 7. The apparatus of claim 6, wherein the upwardly extending structures and the floor define a circular recess. 8. The apparatus of claim 7, wherein the upwardly extending structures are adapted to receive a conventional one gallon paint container and support said conventional one gallon paint container on the floor. 9. The apparatus of claim 8, wherein said upwardly extending structures are adapted to support said plastic container above the floor. 10. The apparatus of claim 6, wherein the floor has an opening extending therethrough for receiving a mounting shaft of the mixing device. 11. The apparatus of claim 1, wherein said retainer comprises 2 pairs of opposing walls, said walls being joined together at four rounded corners. 12. The apparatus of claim 1, wherein the holding structure further comprises at least one clamp for securing the container within the holding structure. 13. An apparatus for mixing paint, said apparatus comprising:(a) a mixing device comprising:a holding structure having a retainer extending from a base, said retainer including a plurality of interior surfaces at least partially defining an interior holding space having a substantially rectangular cross-section, said interior surfaces including a pair of parallel and substantially planar first surfaces and a pair of parallel and substantially planar second surfaces;a mounting support to which the holding structure is secured; andan electric motor connected to the mounting support for rotating the mounting support and the holding structure about at least one axis, wherein the at least one axis comprises a vertical first axis and a second axis that is non-perpendicular to the first axis;(b) a plastic container removably disposed in the interior holding space of the holding structure, said container comprising a body defining an interior volume for holding the paint, said body having a plurality of side wails joined at rounded corners to provide said body with a substantially rectangular cross-section; and(c) a yoke having a balancing arm and a mounting arm to which the mounting support is rotatably connected, said yoke being connected to the electric motor for rotation about the first axis. 14. The apparatus of claim 13, wherein the yoke rotates the hol ding structure in a counter-clockwise direction. 15. An apparatus for mixing paint disposed in a container having a width substantially the equal to the diameter of a conventional one gallon paint container, said apparatus comprising:a holding structure for holding the container during the mixing of the paint, said holding structure comprising:a base having a plurality of upwardly-extending structures disposed around a floor;a retaining structure secured to the base, said retaining structure having a plurality of interior surfaces at least partially defining an interior holding space within which the container is disposed when the holding structure is holding the container, said interior holding space having a substantially rectangular cross section; andwherein the upwardly-extending structures are adapted such that when the retaining structure is holding the container, the container is supported on the floor when the container is a conventional one gallon paint container, and is supported on the upwardly-extending structures, above the floor, when the container has a body with a substantially rectangular cross section; anda mounting support to which the holding structure is secured; andan electric motor connected to the mounting support for rotating the mounting support about at least one axis. 16. The apparatus of claim 15 wherein the interior holding space has a substantially square cross section. 17. The apparatus of claim 15, wherein the upwardly-extending structures and the floor define a circular recess. 18. The apparatus of claim 15, wherein the at least one axis comprises a vertical axis and a second axis that is non-perpendicular to the first axis. 19. The apparatus of claim 15, wherein the base is octagonal. 20. The apparatus of claim 15, wherein the plurality of upwardly extending structures comprises four upwardly extending structures. 21.
