Abstract

A blade assembly for a blending system is shown and described. The blade assembly may include apertures formed through a body. The body may include paddles extending from the body. The blade assembly may be rotated to force a fluid through the apertures. The fluid may be frothed by the apertures.

First claim

What is claimed is:

1 . A whipping blade, comprising:
a body defining a central point through which a central axis extends, the body comprising a first side, a second side, and a peripheral edge extending between the first side and the second side, wherein: four first apertures are formed in the body through the first side to the second side and arranged along a first diameter of the body; four second apertures are formed in the body through the first side to the second side and arranged along a second diameter of the body, and the four first apertures are distinct from the four second apertures; a plurality of elongated apertures are formed in the body through the first side to the second side; each of the plurality of elongated apertures comprises a first arcuate edge positioned a first distance from the central axis, a second arcuate edge positioned a second distance from the central axis, and a pair of straight edges extending therebetween; and the first distance is different from the second distance.

2 . The whipping blade according to claim 1 , wherein the first and second sides are planar surfaces which each meet the peripheral edge at an angle of approximately 90 degrees.

3 . The whipping blade according to claim 1 , wherein the first apertures and the second apertures are circular.

4 . The whipping blade according to claim 1 , wherein each of the first and second apertures are configured such that rotation of the body about the central axis by a blending device forces liquid through the first and second apertures.

5 . The whipping blade according to claim 3 , wherein each of the first and second apertures are configured such that rotation of the body about the central axis by a blending device forces liquid through the first and second apertures.

6 . The whipping blade according to claim 4 , wherein each of the plurality of elongated apertures are configured such that rotation of the body about the central axis by a blending device forces liquid through the plurality of elongated apertures.

7 . The whipping blade according to claim 4 , wherein forcing the liquid through the first and second apertures froths the liquid.

8 . The whipping blade according to claim 1 , wherein the plurality of elongated apertures are arranged such that none of the plurality of elongated apertures intersect with the first and/or second diameters.

9 . The whipping blade according to claim 1 , wherein the first side and the second side are free from protrusions.

10 . The whipping blade according to claim 1 , wherein each of the plurality of elongated apertures includes a major axis and a minor axis, and
wherein no reference line passing through any major axis or minor axis intersects the central axis.

11 . The whipping blade according to claim 1 , wherein the plurality of elongated apertures is four elongated apertures.

12 . The whipping blade according to claim 1 , wherein the whipping blade is provided with only four elongated apertures.

13 . The whipping blade according to claim 1 , wherein the plurality of elongated apertures comprises:
a first elongated aperture through which a first major axis extends, a second elongated aperture through which a second major axis extends; wherein the first elongated aperture is defined opposite the first elongated aperture; and wherein the first major axis and the second major axis do not intersect.

14 . A whipping blade, comprising:
a planar body having a central point through which a central axis extends, the planar body comprising:
a first side,
a second side,
four first circular apertures formed in the planar body through the first side to the second side and arranged along a first diameter of the planar body,
four second circular apertures formed in the planar body through the first side to the second side and arranged along a second diameter of the planar body, wherein the four first circular apertures are distinct from the four second circular apertures,
a plurality of elongated apertures formed through the first side to the second side,
wherein the plurality of elongated apertures are arranged such that none of the plurality of elongated apertures intersect with the first and/or second diameters.

15 . The whipping blade according to claim 14 , wherein none of any elongated apertures provided in the planar body intersect with the first and/or second diameters.

16 . A blender system comprising:
a whipping blade comprising a planar body having a central point through which a central axis extends, wherein: the planar body comprises a first side, a second side, four first circular apertures, four second circular apertures, and a plurality of elongated apertures; the four first circular apertures are formed in the planar body through the first side to the second side and arranged along a first diameter of the planar body; the four second circular apertures are formed in the planar body through the first side to the second side and arranged along a second diameter of the planar body, and the four first circular apertures are distinct from the four second circular apertures; the plurality of elongated apertures are formed through the first side to the second side and arranged such that none of the plurality of elongated apertures intersect with the first and/or second diameters; and in a state in which the whipping blade is installed in the blender system, each of the four first circular apertures, the four second circular apertures, and the plurality of elongated apertures are unobstructed.
