Abstract

A beverage is brewed by infusing heated liquid with a dry beverage medium contained in a first chamber of a disposable cartridge. The cartridge is internally subdivided by a permeable filter separating the first chamber from a second chamber, with both chambers being closed by piercable lid on one side of the cartridge. During a brew cycle, the cartridge is clamped between confronting arms, an the cartridge lid is pierced by inlet and outlet probes carried by a platen and arranged to communicate respectively with the first and second cartridge chambers. Heated liquid is admitted in to the first chamber via the inlet probe for infusion with the dry beverage medium, and the resulting brewed beverage permeates through the filter into the second chamber from which it exits via the outlet probe.

Claims

1. In an apparatus for brewing a beverage by infusing heated liquid with a beverage medium contained in a first chamber of a disposable single serve cartridge, said cartridge being internally subdivided by a permeable filter separating said first chamber from a second chamber, both of said chambers being closed by a piercable lid on one side of said cartridge, a holder for retaining said cartridge during a brew cycle, said holder comprising:

a pair of mutually spaced confronting arms defined opposite sides of a brewing chamber;

first operating means for shifting said arms in opposite directions between retracted positions accommodating insertion and removal of one of said cartridges into and out of said chamber, and advanced position clamping the said one cartridge therebetween;

a platen;

inlet and outlet probes carried by said platen; and

second operating means for shifting said platen in opposite directions between a retracted position at which said inlet and outlet probes are outside of said brewing chamber and spaced from the lid of a cartridge clamped between said arms, and an advanced position at which said inlet and outlet probes pierce said lid and communicate respectively with said first and second chambers, whereupon heated liquid may be admitted into said first chamber via said inlet probe for infusion with said beverage medium, with the resulting brewed beverage permeating through said filter into said second chamber for removal therefrom via said outlet probe.

2. The holder of claim 1 wherein the direction of movement of said platen is orthogonal with respect to the direction of movement of said arms.

3. The holder of claim 1 wherein said platen is provided with multiple inlet probes.
