DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 through 7 thereof, a new mixer embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 7, the fluid mixing apparatus 10 generally comprises a circular lid 16 for engaging an open top 14 of a cylindrical container 12, such as a conventional paint can or a five-gallon paint bucket. The lid 16 has a top side 18, a bottom side 20, a center and a perimeter edge 24. Adjacent the perimeter edge 24, the lid 16 has a spout 26 opening that extends through into the top side 18 and outwardly of the bottom side 20 to permit fluid to be poured from the container 12.

A shaft 28 is rotatably positioned through the lid 16 for rotation about a shaft axis. The shaft 28 extends through an aperture 30 at the center of the lid 16. The shaft 28 has a proximal end 32 and a distal end 34 with respect to the lid 16 in which the proximal end 32 extends upwardly above the top side 18. The proximal end 32 has a handle engaging portion 36 that can engage a handle 38 or a power tool chuck. The length of the shaft 28 may range from approximately 7 inches to approximately 32 inches, or may be approximately 9.5 inches. The length of the shaft 28 may vary depending on the height of the container 12. For example, in a conventional paint can, an approximately 9.5 inch long may be employed. In a conventional five-gallon paint bucked, however, a shaft 28 having a length of approximately 24 to 32 inches may be employed.

A mixer 40 is attached to the shaft 28 adjacent the distal end 34 for rotating with the shaft 28 in a plane that is perpendicular to a longitudinal axis of the shaft 28 extending through the proximal and distal ends. The mixer 40 has a front surface 42, a back surface 44, a top side 46, a bottom side 48, and two lateral sides 50. The top side 46 has an aperture 30 that removably receives the shaft 28. Legs 54 are attached to the bottom side 48 of the mixer 40, extending downwardly adjacent the lateral sides 50. The mixer 40 has a length defined by a distance between the lateral sides 50. The length may be between approximately 4 inches and 7 inches. The mixer 40 has a fixed portion 56 and a hinged portion 58 hingedly connected to the fixed portion 56 for adjusting the length. The hinged portion 58 is movable between a first position and a second position to alter the length between a first length and a second length. The first length may be from approximately 3 inches to 6 inches, or approximately 4.375 inches. The second length may be from approximately 5 to 7 inches, or approximately 6.375 inches.

An agitator 60 is mounted to the shaft 28 for agitating a fluid when the apparatus 10 is mounted in a container 12. The agitator 60 is located between the handle engaging portion 36 and the mixer 40, and can be selected from a variety of agitator 60 configurations. In one configuration, the agitator 60 includes a plurality of U-shaped blades 62 attached to and extending radially outward from the shaft 28 so that the mixer 40 has a U-shaped cross-section taken perpendicular to a longitudinal axis of the mixer 40 extending through the lateral sides 50. In another configuration, the agitator 60 may include a plurality of paddles 64 having a substantially rectangular shape and a chamfer. The paddles 64 may have a configuration of apertures therein for agitating liquid as the agitator 60 is rotated within a liquid.

In use, the apparatus 10 is engaged to the open top 14 of a container 12 (e.g., a conventional paint container 12) and a manually actuated or a powered rotating device rotates the shaft 28 on the shaft axis, and the mixer 40 and agitator 60 attached thereto. This rotation causes agitation in the fluid (e.g., paint) and the fluid is mixed.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure.
