Capsule, system and method for preparing a beverage

A system for preparing a predetermined quantity of beverage suitable for consumption using an extractable product, the system comprising:

• an exchangeable capsule;
• and
• an apparatus comprising a fluid dispensing device for supplying an amount of a fluid, such as water, under a pressure of at least six bar to the exchangeable capsule, and a receptacle for holding the exchangeable capsule;
• wherein the exchangeable capsule comprises
• a circumferential first wall,
• a second wall closing the circumferential first wall at a first end, and
• a flexible sheet-shaped perforate and/or porous third wall closing the circumferential first wall at a second, open, end opposite the second wall,
• wherein the first, second, and third wall enclose an inner space comprising the extractable product,
• wherein the third wall forms an outermost boundary of the capsule in an axial direction thereof, and
• wherein the third wall comprises filtering paper or a nonwoven filtering material;
• wherein the fluid dispensing device is arranged for supplying the fluid to the extractable product through the second wall for forming the beverage;
• and
• wherein the receptacle comprises a support surface, and the third wall is arranged to abut against the support surface for draining the prepared beverage from the capsule through the third wall and through the support surface.

A method for preparing a predetermined quantity of beverage suitable for consumption using an extractable product, the method comprising:

• providing an exchangeable capsule, comprising a circumferential first wall, a second wall closing the circumferential first wall at a first end, and a flexible sheet-shaped perforate and/or porous third wall closing the circumferential first wall at a second, open, end opposite the second wall, wherein the first, second and third wall enclose an inner space comprising the extractable product, wherein the third wall forms an outermost boundary of the capsule in an axial direction thereof, and wherein the third wall comprises filtering paper or a nonwoven filtering material;
• providing an apparatus comprising a receptacle for holding the exchangeable capsule, a fluid dispensing device for supplying an amount of a fluid, such as water, under a pressure of at least six bar to the exchangeable capsule, and an outlet which, in use, is in fluid communication with the capsule for draining the prepared beverage from the capsule and supplying the beverage to a container such as a cup;
• arranging the exchangeable capsule with the third wall in abutment with a support surface of the receptacle;
• and
• supplying the fluid under the pressure to the extractable product for preparing the beverage.
