ABSTRACT:
TECHNICAL FIELD
This invention relates to brewing apparatus and more particularly to brewing apparatus having a prepackage unbrewed drink ingredients.
BACKGROUND OF THE INVENTION
Brewing apparatus typically include a prepackage set of ingredients (coffee, tea, etc.) that are placed in a brewing basket or bin which is a component of the brewing apparatus. The maker adds water to the brewing apparatus in a chamber that is designed to heat the water and cause the heated water to flow over the prepackaged ingredients. The process of preparing the brewed drink consists of 1. opening the brewing bin, 2. inserting a filter or a prepackaged mix, 2
a
. measuring the ingredients for the brew if not prepackaged, 3. adding a measured amount of water, 4. close the brewing bin, 5. place the carafe on the apparatus in a position to collect the brewed beverage, and turn on the brewing apparatus.
To accomplish this process many different designs of coffee makers have been proposed. All require the above process to make household type coffee. All of the prior art devices have an on board water tank, brew bin and require a filter. Filling the water tank has vulnerability for spillage. Filling the brew bin with coffee grounds allows the possibility to spill grounds outside the filter either on the counter, floor, or between the filter and the inner wall of the brew bin which introduces coffee grounds into the finished product.
Two ingredients water and coffee grounds influence the quality and consistency of a cup of coffee. Tap water is usually used for consumer coffee making. Tap water flavor varies depending on the treatment of the water and the region. Using the exact volume of water to a constant measurement of coffee is the only way to assure a consistent cup of coffee still vulnerable to the quality of the water and coffee.
Ground coffee is typically sold by the pound in resealable cans and bags. The can or bag of coffee is typically vacuum-sealed and after opening oxygen begins to affect the quality of the coffee grounds. The freshest cup of coffee produced is after the coffee container is first open and the quality deteriorates thereafter.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an improved beverage brewing apparatus and method.
In one aspect of the present invention, brew ingredients and water are pre-measured and sealed in a cartridge. In another aspect of the present invention, the water and brew ingredients are sealed in separate compartments of the cartridge. In yet another aspect of the present invention, a housing with a heating unit.
In still another aspect of the present invention, the brewing chamber has a shape complementary to at least a portion of the cartridge. In yet still another aspect of the present invention, the cartridge has a cap or cover portion adapted to seal against a rim portion of the housing. In a further aspect of the present invention, a valve assembly is installed in a lower portion of the housing to pierce the water compartment and control the flow of water over the heating unit.
In a yet further aspect of the present invention, a second piercing element is positioned to pierce the brew ingredients compartment to permit the passage of heated water to flow from the heating unit to the brew ingredients compartment. In a stir further aspect of the present invention, a third piercing element is positioned to pierce the brew ingredients chamber to direct the flow of a brewed beverage from the brew ingredients chamber to a drinking vessel. In a yet still further aspect of the present invention, the housing has a sensor positioned to initiate the brewing process when the cartridge is firmly and properly installed on the housing.
In a still further aspect of the present invention, a separate water cartridge and separate brew ingredients cartridge can be utilized to permit the user to combine any of the brew ingredients with any water cartridge or to heat water only.
In accordance with the object and aspects, the present invention:
Provides a prepackaged cartridge of water and brew ingredients,
Provides a housing in which to secure the prepackaged cartridge,
Provides a fresh brewed beverage.
