Abstract

The present invention is related to a device and method for dispensing dual component liquids or concentrates packaged in separate containers to provide protection from effects such as oxidation and moisture loss. The liquids or concentrates can be dispensed through a pumping system, preferably including a peristaltic pump, mixed together, and optionally diluted with another liquid, such as water, to provide a consumable beverage. In addition, the device of the present invention can dispense liquids or concentrates having different viscosities, such that they are mixed together in the proper ratio.

Claims

1. A method for automatically preparing and dispensing a beverage product containing at least two different components, which method comprises:

providing and retaining at least two different components in separate compartments of a single packaging assembly, wherein the components are capable of forming a beverage after being combined;

pumping the at least two different components from the separate compartments of the packaging assembly at a predetermined rate suitable for combining the at least two different components and to withdraw them from the compartments in a uniform manner relative to each other;

combining the at least two pumped components by withdrawing them from the packaging assembly and mixing them together, optionally with a diluent, in relative amounts to form a consumable beverage product; and

dispensing the consumable beverage product for consumption by a consumer.

2. The method of claim 1, wherein the components have different viscosities, and wherein a diluent having a viscosity is combined with the components, with at least one of the components having a viscosity that is greater than double that of the diluent.

3. The method of claim 1, wherein the diluent comprises water, carbonated water, a milk or non-dairy milk product, a solution containing any of these, or a mixture thereof.

4. A method for improving quality of a dispensed coffee beverage containing at least two different components from a dispensation system, which method comprises:

providing and retaining at least two different components in separate compartments of a single removable packaging assembly of the dispensation system, wherein the components are capable of forming a coffee beverage after being combined;

pumping the at least two different components from the separate compartments of the packaging assembly and combining the at least two components by mixing them together, optionally with a diluent, in relative amounts to form a consumable beverage product; and

dispensing the consumable beverage product for consumption by a consumer.

5. The method of claim 4 wherein the at least two different components are pumped from the separate compartments of the packaging assembly at a predetermined rate suitable for combining the at least two different components and to withdraw them from the compartments in a uniform manner relative to each other at substantially the same time.

6. The method of claim 4, wherein the packaging assembly is a single chamber of a polymer film that is divided to form the compartments.

7. The method of claim 4, wherein one component is a coffee base concentrate that is substantially free of coffee aroma, and another component is a coffee aroma.

8. The method of claim 4, wherein handling and loading of the at least two components into the dispensation system is facilitated by providing compartments that are separated but secured together, each compartment comprising a fitment adapted to connect to a complementary gland of the dispensation system.

9. The method of claim 8, wherein the at least two compartments are secured together by heatsealing or using an adhesive.

10. The method of claim 8, wherein the at least two compartments are secured together within a single outer container.

11. A method for dispensing a beverage product containing at least two different components, which method comprises:

providing and retaining at least two different components in separate compartments of a single packaging assembly, wherein the components are capable of forming a beverage after being combined and the compartments contain relative amounts of each component, such that each compartment empties uniformly relative to the other compartment(s) at a determined rate;

combining the at least two components by withdrawing them from the packaging assembly and mixing them together, optionally with a diluent, in an addition chamber operatively associated with the compartments of the packaging assembly to form a mixture; and

dispensing the mixture as a beverage product or beverage-forming product for consumption by a consumer using a pump assembly associated with the addition chamber.

12. The method of claim 11 wherein the system includes means for providing a diluent to the mixture of the least two components to provide a diluted beverage product.

13. The method of claim 12, wherein the means for providing a diluent comprises a diluent tank filled with one of water, carbonated water, a milk or non-dairy milk product, a solution containing any of these, or a mixture thereof.

14. The method of claim 13, wherein the diluent tank is filled with water or an aqueous solution so that the beverage product that is dispensed is a non-carbonated beverage, a coffee or tea beverage, or a creamy beverage.

15. The method of claim 11, wherein the beverage is dispensed through a pump assembly that comprises dual-head or multi-head volumetric positive displacement pumps.

16. The method of claim 15, wherein the volumetric positive displacement pumps are peristaltic pumps.

17. The method of claim 11, wherein the packaging assembly includes dual compartments for retaining the components therein.

18. The method of claim 11, wherein the packaging assembly is a single chamber of a polymer film that is divided to form the compartments.

19. The method of claim 18, wherein each compartment includes a fitment to dispense the components from the compartments.

20. The method of claim 11 wherein the packaging assembly is made of a barrier polymer film that is processed to form separate gas-, liquid-, and light-hermetic compartments.
