Abstract

A lid for a food processing device with a rotating blade within a vessel has an one-way valve for allowing air to escape the vessel.

First claim

What is claimed is:

1. A lid for a vessel of a food or beverage processing device, the lid comprising:
a body portion having a peripheral seal that contacts the vessel;
the lid having a one-way valve for air, the one-way valve oriented to allow air to escape from the vessel;
the one-way valve being incorporated into a measuring cup that is received by an opening in the lid;
the one-way valve comprising a lip seal, the opening having a surface that cooperates with the lip seal.

2. The lid of claim 1 , wherein:
bayonet features extend between the lid and the measuring cup.

3. The lid of claim 1 , wherein:
the one-way valve is located within a well so as to flush mount with respect to an upper surface of the lid.

4. The lid of any one of claim 3 , wherein:
the lid has a pull tab to facilitate its removal from the vessel.

5. The lid of claim 1 , wherein:
the lid has a vacuum relieve valve.

6. The lid of claim 5 , wherein:
the relief valve is incorporated into a pull ring.

7. The lid of claim 1 , wherein:
the measuring cup has relief areas that act as finger grips for installing and removing the cup.

8. The lid of claim 1 wherein:
the opening further comprises a tapered pilot surface.

9. The lid of claim 1 , wherein:
the vessel is a blender jug.

10. In combination, the lid of claim 1 , and:
a vessel having an internal rotating blade, the vessel being sealed by the lid.

11. The lid of claim 1 , wherein:
the measuring cup has a circumferential seal.

12. The lid of claim 11 , wherein:
the circumferential seal extends outward and downward.

13. The lid of claim 12 , wherein:
the lid has a pilot surface against which the circumferential seal flexes when in a fully installed orientation.

14. The lid of claim 13 , wherein:
the measuring cup has a fully installed orientation where the seal operates as a check valve.

15. The lid of claim 13 , wherein:
the circumferential seal has a lip that exerts a force on the pilot surface that assists in a removal of the measuring cup.

16. The lid of claim 1 wherein:
the measuring cup is received within a cylindrical opening in the lid;

a lower rim of the cylindrical opening having ramped portions that cooperate with a male bayonet feature on the measuring cup.

17. The lid of claim 1 , wherein:
the measuring cup is received within a cylindrical opening in the lid;

a lower rim of the cylindrical opening having a ramped portion that cooperates with a male bayonet feature on the measuring cup;
rotation of the measuring cup causing the ramped portion to draw the measuring cup into engagement with a lower portion of the cylindrical opening comprising an internal shelf.

18. The lid of claim 1 , wherein:
a gap external to the measuring cup forms a passageway for air to flow towards the lip seal.
