A paint can cover or lid having a paint mixing device rotatably supported therefrom and extending into the interior of the paint can for mixing paint in the can while the cover or lid is in place to form a closure for the can. The mixer includes a paddle rotatably supported from the paint can cover or lid and a rotatable member which extends rotatably through the paint can cover or lid in a sealed manner to prevent leakage of paint and entrance of air with the outer end of the rotatable member having a polygonal socket receiving the output of a power device. In one embodiment of the invention, the paint can lid or cover is provided with an opening therein receiving an adapter secured to and sealed to the cover or lid by a threaded nut with the rotatable member extending through the adapter in sealed relation thereto. In another embodiment of the invention, the paint can cover or lid is of one piece plastic construction with a central adapter portion having an opening sealingly receiving and supporting a rotatable member capable of being connected to a power source at its upper end. In each embodiment of the invention, the rotatable member supports a paddle extending to a position adjacent the bottom and peripheral wall of the paint can for thoroughly agitating and mixing paint prior to its use with the cover forming a sealed closure for the paint can to retain all of the paint in the can while the paint is being mixed.
A paint can cover with mixer comprising a circular member forming a cover for a paint can, a rotatable member extending through said circular member, means rotatably supporting the rotatable member and sealing the rotatable member in relation to the circular member, said rotatable member having an upper end provided with means receiving rotational power from a power source to rotatably drive the rotatable member, and paddle means mounted on a lower end of said rotatable member and extending into a paint can for mixing paint in the can, said circular member including a central adapter portion having said bore formed therein, said adapter portion including a cylindrical body having a generally cylindrical vertical bore receiving said rotatable member with said rotatable member having a bottom extending below said body, said bore including first seal means mounted therein intermediate the ends in sealing engagement with the rotatable member and second seal means bridging the rotatable juncture between the rotatable member and a bottom end of said cylindrical body, each of said seal means being an O-ring seal, said first seal means being positioned in a groove in said body in communication with said bore and sealingly engaging the periphery of said rotatable member, said second seal means being positioned in a groove in the periphery of said rotatable member and sealingly engaging a lower end of said body, said body including a larger diameter bore at the upper end of said bore with the larger diameter bore defining an upwardly facing shoulder, said rotatable member including a peripheral, radially outwardly extending flange at an upper end thereof, said flange being received in the larger diameter bore and engaging said shoulder thereby limiting inward movement of the rotatable member into said body.
A paint can cover with mixer comprising a circular member forming a cover for a paint can, a rotatable member extending through said circular member, means rotatably supporting the rotatable member and sealing the rotatable member in relation to the circular member, said rotatable member having an upper end provided with means receiving rotational power from a power source to rotatably drive the rotatable member, and paddle means mounted on a lower end of said rotatable member and extending into a paint can for mixing paint in the can, said circular member including a generally cylindrical vertical bore receiving said rotatable member, said bore including seal means mounted therein intermediate the ends in sealing engagement with the rotatable member, said circular member including, a central adapter having said bore formed therein, said adapter including a cylindrical body, said circular member having an opening receiving the body therethrough, said body having a peripheral flange at an upper end thereof engaging an upper surface of the circular member adjacent the periphery of the opening therethrough to limit insertion of the body through the opening in the circular member, said body having an externally threaded lower portion having a periphery enabling it to be inserted through the opening in the circular member, an internally threaded nut on the threaded portion of the body member below the circular member, said nut extending radially outwardly beyond said opening and a seal extending peripherally of the opening between the nut and a lower surface of the circular member to form a seal between the adapter and circular member, said body including a larger diameter bore at the upper end of said bore with the larger diameter bore defining an upwardly facing shoulder, said rotatable member including a peripheral, radially outwardly extending flange at an upper end thereof, said flange being received in the larger diameter bore and engaging said shoulder thereby limiting inward movement of the rotatable member into said body, said rotatable member extending downwardly below a bottom end of said nut and body, a peripheral seal bridging the rotatable juncture between the rotatable member and the interior of said bore thus forming a double seal between the rotatable member and body of the adapter.
