Abstract:
1. A system for selectively delivering different beverages having different foam levels by injection of a fluid under pressure into a capsule that contains a beverage-forming substance, the capsule including a chamber containing the substance and a beverage dispensing structure adapted to retain an extraction pressure in the chamber before allowing the beverage to flow out of the capsule the system comprising: an extraction device and first and second capsules, wherein the first and second capsules each include a substantially identical external configuration and shape, with a lower portion of each capsule configured and positioned to collect the beverage prior to dispensing it, and wherein the lower portion of each capsule has an opening that forms an outflow passage for dispensing the beverage to the user without contacting or contaminating other portions of the system; the capsules being provided for selective use in the extraction device, with the first capsule having a first beverage dispensing structure so constructed and arranged to retain a first extraction pressure in the capsule, prior to the complete delivery of the beverage, and the second capsule having a second beverage dispensing structure so constructed and arranged to retain a second extraction pressure in the capsule, prior to the complete delivery of the beverage, with the first extraction pressure being greater than the second extraction pressure so that a greater amount of foam is produced upon delivery of the beverage from the first capsule as compared to that produced by the second capsule, so that a user of the system can select a cartridge that produces a beverage with the desired foam content.
