Abstract

A single chamber brewing device for brewing beverage has a single brewing chamber for receiving water and a brewing material such as tea, a thermally controlled heating element, and a thermally controlled valve for releasing brewed beverage from the brewing chamber into a container positionable underneath the brewing chamber.

Claims

1. A brewing device for preparing and containing a brewed beverage, the device comprising,

a brewing chamber adapted to receive a brewing material and liquid, the brewing chamber comprising a heat source for supplying heat to liquid in the brewing chamber, whereby the brewing material is brewed in the brewing chamber as the liquid is heated in the brewing chamber, and

a valve disposed in an opening in the brewing chamber, the valve operative to release brewed beverage from the brewing chamber through the opening, and

a brewed beverage container positionable to receive brewed beverage released from the brewing chamber.

2. The brewing device of claim 1 wherein the brewing chamber is supportable by the brewed beverage container.

3. The brewing device of claim 1 wherein the brewing chamber comprises a housing and metal casing within said housing.

4. The brewing device of claim 3 wherein the heat source is an electrical resistance element attached to the metal casing of the brewing chamber.

5. The brewing device of claim 4 further comprising switch means for controlling current to the electrical resistance element.

6. The brewing device of claim 4 further comprising a thermal limiting fuse in a circuit which supplies current to the electrical resistance element.

7. The brewing device of claim 4 further comprising a temperature limiting thermostat which controls the flow of current to the electrical resistance element.

8. The brewing device of claim 3 further comprising a moisture seal between the metal casing and the housing.

9. The brewing device of claim 3 wherein the housing further comprises a handle.

10. The brewing device of claim 1 wherein the valve is thermally responsive to heat generated by the heat source.

11. The brewing device of claim 1 wherein the valve is a bi-metal snap action valve.

12. The brewing device of claim 1 further comprising a cover over the valve adapted to support a brewing material within the brewing chamber.

13. The brewing device of claim 1 wherein a lower portion of the brewing chamber is contoured to engage an upper portion of the brewed beverage container.

14. The brewing device of claim 1 wherein the brewed beverage container further comprises a handle.

15. The brewing device of claim 1 wherein an opening in the brewing chamber is dimensioned substantially the same as an opening in the brewed beverage container.

16. The brewing device of claim 1 further comprising a cover dimensioned to cover an opening in the brewing chamber.

17. A brewing device for preparing brewed beverage comprising a brewing chamber for receiving a brewing liquid and a brewing material, a heat source attached to and in thermal communication with the brewing chamber, and a thermally responsive valve for controlling release of brewed beverage from the brewing chamber through an opening in the brewing chamber.

18. The brewing device of claim 17 wherein the brewing chamber is configured to be engagable with a brewed beverage receptacle.

19. The brewing device of claim 17 wherein the brewing chamber is comprised of a metallic material housed by a plastic material.

20. The brewing device of claim 17 wherein the heat source is an electrical resistance element attached to the metallic material, and further comprising a current controlling circuit connected to the resistance element and within the plastic housing.

21. A brewing device for brewing a beverage by a steeping process wherein a beverage making material is submerged in water which is heated in brewing chamber to a predetermined temperature, the brewing device comprising,

a steeping chamber for receiving a brewing material and a liquid, said steeping chamber having a valve-controlled opening through which brewed beverage can exit the steeping chamber, the valve-controlled opening comprising a valve positioned about an opening in the steeping chamber, the valve operative to open in response to heat,

an electrically powered heat source in thermal communication with the steeping chamber to heat liquid in the steeping chamber, and

a cover for steeping chamber.

22. A brewing device for brewing a beverage by a steeping process in which a brewing material is submerged in liquid which is heated for a period time and to a temperature at which flavor from the brewing material is extracted into the liquid to produce a heated brewed beverage, the brewing device comprising a single chamber for receiving a quantity of a brewing material and a quantity of liquid, a controlled electric heat source in thermal communication with said chamber for heating the liquid in said brewing chamber to brew the brewing material in said chamber, and a thermally responsive valve in said chamber which opens to release brewed beverage from said container in response to heat generated by said heat source.
