Blending system

1. A blending system comprising:

a base encasing a motor and a splined coupler;

a blade assembly comprising a first side and a second side, the first side comprising one or more blades and the second side comprising a spline, wherein the spline operatively interfaces with the splined coupler, and wherein the blade assembly is selectively engagable with the base;

a container selectively engaged with the blade assembly; and

a gasket operatively positioned between the container and blade assembly, the gasket comprising at least one protrusion extending from a narrow portion and positioned between the container and blade assembly,

wherein the at least one protrusion and the narrow portion operatively create an air-tight seal between the blade assembly and container at a first pressure and allow gas to exit between the container and blade assembly at a second pressure while operatively generally preventing solids from exiting between the container and the blade assembly.

2. The blending system of claim 1 , wherein the gasket has a generally X-shaped cross-section.

3. The blending system of claim 2 , wherein the generally X-shaped cross-section of the gasket has a diameter of the narrow portion, d N , and a diameter of a distended portion including the at least one protrusion, d D , wherein d N< d D .

4. The blending system of claim 3 , wherein the first pressure is less than the second pressure.

5. The blending system of claim 1 , wherein the first pressure is less than the second pressure.

6. The blending system of claim 1 , wherein the gasket operatively prevents liquids from exiting between the container and blade assembly at the second pressure.

7. A blending system comprising:

a container comprising an open end and a closed end;

a blade assembly comprises one or more blades and a spline, wherein the blade assembly is selectively engagable with the open end of the container such that the one or more blades extend within the container and the spline extends away from the open end; and

a gasket operatively positioned between the container and blade assembly, the gasket comprising a generally distended portion extending from a general center, and

wherein the gasket operatively prevents liquids and solids from exiting between the container and blade assembly while allowing gas to exit the container at a threshold pressure level.

8. The blending system of claim 7 , wherein the generally distended portion comprises one or more protrusions.

9. The blending system of claim 7 , wherein the generally distended portion extending from the general center forms a generally X-shaped cross-section.

10. The blending system of claim 7 , wherein the generally distended portion comprises rounded edges.

11. The blending system of claim 10 , wherein intersections of the generally distended portion are generally concave.

12. The blending system of claim 7 , wherein the gasket is operatively positioned between the container and the blade assembly, and

wherein at least one side of the gasket is uncovered when the blending system is in operation.

13. A blending system comprising:

a base encasing a motor;

a container;

a blade assembly selectively engaged with an open end of the container, wherein the blade assembly is selectively positioned between the base and the container in an operative position; and

a gasket positioned between the container and blade assembly,

wherein the gasket operatively creates an air-tight seal between the blade assembly and container at a first pressure and allows gas to exit between the container and blade assembly at a second pressure during operation of the motor such that the blending system remains operational.

14. The blending system of claim 13 , wherein the gasket transitions from a first state defined by allowing gas to exit to a second state defined by preventing gas from exiting as pressure changes from the second pressure to the first pressure.
