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 blade assembly operatively attached to a blender system, the blade assembly comprising:
a generally planar body, the body comprising:
first and second sides;
a generally cylindrical sidewall perpendicular with the first and second sides;
a plurality of apertures formed through the body that operatively allows a liquid to pass from the first side of the body to the second side of the body, wherein the plurality of apertures each comprises a first edge and a second edge, and wherein at least one of the first edge or the second edge comprises a tapered portion, wherein the plurality of apertures are arranged in an X-shape on the body; and
at least one paddle protruding from the second side of the body;

wherein the at least one aperture froths the liquid.

2. The blade assembly of claim 1 , wherein the plurality of apertures each comprises an aperture wall and the at least one paddle comprises a paddle wall, and wherein the aperture wall seamlessly transitions into the paddle wall.

3. The blade assembly of claim 1 , wherein the body further comprises an aperture configured to receive a drive shaft.

4. The blade assembly of claim 1 , wherein the body represents a disk shape.

5. The blade assembly of claim 1 , wherein the at least one paddle comprises a wedge shape.

6. The blade assembly of claim 1 , wherein the body comprises a food-grade plastic.

7. The blade assembly of claim 1 , wherein the body comprises a plurality of wings.

8. A whipping blade for a blender system, the whipping blade comprises:
a body comprising a first side, a second side, a cylindrical peripheral edge, and a plurality of apertures formed through the first side to the second side, wherein at least one aperture of the plurality of apertures is disposed proximal a perimeter of the body and comprise a tapered portion proximal to at least one of the first side or second side of the body and wherein the peripheral edge is generally perpendicular with the first and second sides and the plurality of apertures are arranged in an X-shape on the body in line with a central point on the body; and
wherein the plurality of apertures froth a liquid.

9. The whipping blade of claim 8 , wherein the body further comprises a flattened portion and a raised portion.

10. The whipping blade of claim 9 , wherein the flattened portion transitions to the raised portion via a curved surface.

11. The whipping blade of claim 9 , wherein the flattened portion is closer to a bottom of a blending container than the raised portion when the whipping blade is operatively attached to the blending container.

12. The whipping blade of claim 8 , wherein the body further comprises at least one paddle protruding from the body.

13. The whipping blade of claim 8 , wherein the body comprises a generally circular shape.

14. The whipping blade of claim 8 , wherein the plurality of apertures are disposed generally equal distance from each other and generally about a center of the body.

15. The whipping blade assembly of claim 8 , wherein the plurality of apertures are generally normal with a surface of the body.

16. The whipping blade of claim 8 , wherein the body is generally solid apart from the apertures and wherein the body has a planar top and bottom.

17. The blade assembly of claim 1 further comprising a plurality of elongated apertures arranged on the body out of line with a central axis of the body.

18. The whipping blade of claim 8 further comprising a plurality of elongated apertures arranged on the body out of line with the central axis of the body.
