Abstract
Abstract An apparatus for mixing liquids by hand is described comprising a handle having an upper and a lower portion. Extending from the lower portion is slotted mixing blade means and terminating the lower portion there is provided a salient surface for preventing the slotted blade means from rubbing against an underlying surface and for reducing friction between the apparatus and the surface when the apparatus is placed against and rotated about a line perpendicular to the surface.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
128 words
An apparatus for mixing liquids, comprising: a handle having an upper and a lower portion, said lower portion terminating in a salient surface; and one or more slotted mixing blades attached to the lower portion of the handle; wherein said one or more slotted mixing blades are first, second and third blades, said first slotted mixing blade forms an outer circular ring and is planar with its plane perpendicular to said handle and its center concentric with the center of the handle, and said second and third slotted mixing blades are rectangular and planar, and perpendicular and parallel to the handle, and the second and third blades bisect the handle and the handle bisects the second and third blades, and the first blade forms an outer circular ring.
Claim 2
Independent Claim
128 words
An apparatus for mixing liquids, comprising: a handle having an upper and a lower portion, said lower portion terminating in a salient surface; and one or more slotted mixing blades attached to the lower portion of the handle; wherein said one or more slotted mixing blades are first, second and third blades, said first slotted mixing blade forms an outer circular ring and is planar with its plane perpendicular to said handle and its center concentric with the center of the handle, and said second and third slotted mixing blades are rectangular and planar, and perpendicular and parallel to the handle, and the second and third blades bisect the handle and the handle bisects the second and third blades, and the first blade forms an outer circular ring.
Claim 3
Independent Claim
68 words
An apparatus for mixing liquids, comprising: a handle having an upper and a lower portion, said lower portion terminating in a salient surface; and one or more slotted mixing blades attached to the lower portion of the handle; wherein said one or more slotted mixing blades is one circular mixing blade with its plane perpendicular to said handle and its center concentric with the center of the handle.
Claim 4
Independent Claim
68 words
An apparatus for mixing liquids, comprising: a handle having an upper and a lower portion, said lower portion terminating in a salient surface; and one or more slotted mixing blades attached to the lower portion of the handle; wherein said one or more slotted mixing blades is one circular mixing blade with its plane perpendicular to said handle and its center concentric with the center of the handle.
Claim 5
Dependent Claim
17 words
The apparatus of claim 2 wherein said circular mixing blade has one or more deflectors attached thereto.
Claim 6
Dependent Claim
17 words
The apparatus of claim 2 wherein said circular mixing blade has one or more flaps attached thereto.
Claim 7
Dependent Claim
19 words
The apparatus of claim 2 wherein said circular mixing blade is corrugated by alternating upward and downward radial bends.
Claim 8
Independent Claim
75 words
An apparatus for mixing liquids, comprising a hollow cylindrical handle sealed in a fluid-tight manner on all surfaces, having an upper and a lower portion, said lower portion terminating in a conical surface, said upper portion having a friction surface so that the handle may be rapidly rotated by hand, and one or more mixing blades attached to the lower portion of the handle, each of said mixing blades containing one or more internal slots.
Claim 9
Independent Claim
75 words
An apparatus for mixing liquids, comprising a hollow cylindrical handle sealed in a fluid-tight manner on all surfaces, having an upper and a lower portion, said lower portion terminating in a conical surface, said upper portion having a friction surface so that the handle may be rapidly rotated by hand, and one or more mixing blades attached to the lower portion of the handle, each of said mixing blades containing one or more internal slots.
Claim 10
Dependent Claim
112 words
A hand-operated apparatus for mixing comprising: an elongated hollow tubular member; a friction surface covering a portion of one end of the tubular member for reducing the force which would otherwise be required to rotate the tubular member between a person's palms; slotted blade means extending outwardly from a portion near the opposite end of the tubular member; and means forming a conically shaped pivot surface terminating the opposite end of the tubular member for preventing the slotted blade means from rubbing against an underlying surface and for reducing friction between the apparatus and the surface when the mixing apparatus is placed against and rotated about a line perpendicular to the surface.
Claim 11
