Abstract

A blending system is shown and described herein. The blending system may include a base including a motor, a blade assembly selectively and operably engaged with the base, where the motor drives the blade assembly, and a container having a cavity. The container includes a flute protruding from an inner surface. An exaggerated flute may extend closer to the blade assembly than the flute.

Claims (28)

1. A blade assembly for a blender system, the blade assembly comprising:

a top blade comprising a first wing extending outwardly from an axis, and a second wing extending outwardly from the axis, wherein the first wing comprises a first tab extending from a body of the first wing, and the second wing comprises a second tab extending from a body of the second wing; and

a bottom blade comprising a first bottom wing and a second bottom wing,

wherein the first bottom wing comprises:

a trailing edge substantially removed of material such that the trailing edge forms a first convex curve and a concave curve adjacent to and vertically offset from the first convex curve;

a radially outermost edge, wherein the radially outermost edge forms a second convex curve adjacent to and vertically offset from the concave curve of the trailing edge, and

a first offset portion on a first plane disposed below a plane of a mounting portion of the bottom blade in a system vertical direction, and

wherein the second bottom wing comprises a second offset portion on a second plane disposed above the plane of the mounting portion of the bottom blade in the system vertical direction.

2. The blade assembly of claim 1 , wherein the body of the second wing is pitched relative the body of the first wing.

3. The blade assembly of claim 1 , wherein the first plane and the second plane are not coplanar.

4. The blade assembly of claim 1 , wherein the concave curve of the trailing edge of the first bottom wing is positioned on the first offset portion, wherein the second bottom wing comprises a second trailing edge that forms a concave curve positioned on the second offset portion vertically offset from the first offset portion.

5. The blade assembly of claim 1 , wherein the first tab extends at an angle relative a plane of the body of the first wing.

6. The blade assembly of claim 5 , wherein the first wing further comprises a wing tip extending from the body of the first wing, wherein the wing tip extends at an angle in an opposed direction with the first tab.

7. The blade assembly of claim 6 , wherein the second tab extends at an angle relative the plane of the body of the first wing.

8. A blade assembly for a blender system, the blade assembly comprising:

a top blade comprising a first wing extending outwardly from an axis, and a second wing extending outwardly from the axis, wherein the first wing comprises a first tab extending from a body of the first wing, and the second wing comprises a second tab extending from a body of the second wing; and

a bottom blade comprising a first bottom wing and a second bottom wing,

wherein the first bottom wing comprises:

a leading edge extending in a direction substantially perpendicular to the top blade;

a trailing edge forming a first convex curve and a concave curve adjacent to and vertically offset from the first convex curve;

a radially outermost edge disposed between the leading edge and the trailing edge, wherein the radially outermost edge forms a second convex curve adjacent to and vertically offset from the concave curve of the trailing edge, and

a first offset portion on a first plane disposed below a plane of a mounting portion of the bottom blade in a system vertical direction, and

wherein the second bottom wing comprises a second offset portion on a second plane disposed above the plane of the mounting portion of the bottom blade in the system vertical direction.

9. The blade assembly of claim 8 , wherein the body of the second wing is pitched relative the body of the first wing.

10. The blade assembly of claim 8 , wherein the first plane and the second plane are not coplanar.

11. The blade assembly of claim 8 , wherein the first tab extends at an angle relative a plane of the body of the first wing.

12. The blade assembly of claim 11 , wherein the first wing further comprises a wing tip extending from the body of the first wing, wherein the wing tip extends at an angle in an opposed direction with the first tab.

13. The blade assembly of claim 12 , wherein the second tab extends at an angle relative the plane of the body of the first wing.
