Abstract

A beverage is prepared employing a package containing at least one beverage ingredient, e.g. roast and ground coffee. The package (10;200) is located at a brewing station, the package is pierced by a tool (49;248) to form an outlet opening (38;202) in the package, an aqueous medium, e.g. hot water, is introduced into the package, the aqueous medium is allowed to commingle with the beverage ingredient, and the beverage so formed is collected through the outlet formed in the package. The piercing tool is employed both to form the outlet opening, and to fold the material (117;204) surrounding the opening out of the path of the beverage which subsequently emerges through the outlet opening.

Claims

1. A method of preparing a beverage employing a package having a sealed outlet with a counterbore containing at least one beverage ingredient comprising locating said package at brewing station;

piercing the sealing material of said package at said sealed outlet with a tool to form an outlet opening in the package;

introducing through an inlet means an aqueous medium into the package allowing the aqueous medium to co-mingle with the beverage ingredient and collecting the beverage so formed through the outlet opening formed in the package;

wherein the piercing tool is employed both to form the outlet opening and to fold within the counterbore of said outlet opening the sealing material surrounding said opening out of the path of the beverage which subsequently emerges through the outlet opening.

2. A method as claimed in claim 1 wherein prior to introducing the aqueous medium, the piercing tool is withdrawn both from the outlet opening and out of the path of the beverage which emerges through the outlet.

3. A method as claimed in claim 1, wherein the sealed outlet has a trough adjacent the outlet, and the piercing action of the tool folds the material covering the outlet into the trough thereby moving the material out of the path of the beverage which emerges through the outlet.

4. A method as claimed in claim 1 wherein the package is pierced by the tool from below.

5. A method as claimed in claim 1 wherein the package is engaged at a point of entry and conveyed to the brewing station.

6. A method as claimed in claim 1 wherein the package is clamped at the brewing station prior to the package being pierced to form the outlet opening.

7. A method as claimed in claim 1 wherein the passage of the aqueous medium is followed by a burst of compressed air thorugh the package.

8. A method as claimed in claim 1 wherein the package after use is ejected from the brewing station.
