Patent ID: 7552885

Claim:
A blender blade for cutting through a working medium provided in a blender pitcher, comprising a body portion having an upper surface and a lower surface, said body portion including an aperture effectively defining an axis of rotation for the blender blade; a first blade wing extending from said body portion and having an upper surface and a lower surface, said upper surface of said body portion smoothly transitioning into said upper surface of said first blade wing; a second blade wing extending from said body portion and having an upper surface and a lower surface, wherein said first blade wing and said second blade wing are asymmetrically oriented with respect to said body portion, said upper surface of said second blade wing being obtusely oriented relative to said body portion; a sharp beveled leading edge provided on said first blade wing and a sharp beveled leading edge provided on said second blade wing, said leading edges thereby being adapted to cut through the working medium during rotation of said blender blade; a trailing edge on said first blade wing opposed to said leading edge on said first blade wing, and a trailing edge on said second blade wing opposed to said leading edge on said second blade wing; a wing flap extending downwardly from said trailing edge of said first blade wing and said trailing edge of said second blade wing, wherein said wing flaps are canted inwardly at a cant angle to control the radial flow of the working medium relative to the axis of rotation; and a wing tip extending upwardly at an obtuse angle from the end of said first blade wing and from the end of said second blade wing.
