Capsule for containing beverage ingredients

Abstract

A capsule for containing beverage ingredients may be designed for insertion in a beverage production device in which a liquid under pressure enters the capsule (in order to interact with the ingredients in the capsule) to drain a beverage from the capsule, wherein the capsule comprises a circumferential first wall, a second wall closing the circumferential first wall at a first end, and a third wall closing the circumferential first wall at a second, open, end opposite the second wall, the first, second and third wall enclosing an inner space comprising the beverage ingredients, wherein the capsule comprises a sealing member for achieving a sealing effect with a beverage production device, wherein at least an external surface of the sealing member comprises a fibrous and/or paperlike material to achieve the sealing effect.

1 . A capsule for containing beverage ingredients, the capsule being designed for insertion in a beverage production device in which a liquid under pressure enters the capsule in order to interact with the ingredients in the capsule to drain a beverage from the capsule, the capsule comprising:
 a circumferential first wall;   a second wall closing the circumferential first wall at a first end; and   a 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 beverage ingredients,   wherein the capsule comprises a sealing member for achieving a sealing effect with a beverage production device, and   wherein at least an external surface of the sealing member comprises a fibrous and/or paperlike material to achieve the sealing effect.   
     
     
         2 . The capsule of  claim 1 , wherein the fibrous and/or paperlike material is paper. 
     
     
         3 . The capsule of  claim 1 , wherein the sealing member consists of the fibrous and/or paperlike material. 
     
     
         4 . The capsule of  claim 1 , wherein the sealing member is provided by at least one sheet that is made of the fibrous and/or paperlike material. 
     
     
         5 . The capsule of  claim 1 , wherein the first, second and/or third wall is provided with the sealing member. 
     
     
         6 . The capsule of  claim 1 , wherein the first, second and/or third wall is substantially made of the fibrous and/or paperlike material, to provide the sealing effect during operation. 
     
     
         7 . The capsule of  claim 1 , wherein the fibrous and/or paperlike sealing member is ring shaped. 
     
     
         8 . The capsule of  claim 1 , wherein the fibrous and/or paperlike sealing member is configured to absorb water during operation. 
     
     
         9 . The capsule of  claim 1 , wherein the sealing member contains a water repellent substance. 
     
     
         10 . The capsule of  claim 1 , wherein the fibrous and/or paperlike material covers at least part of one of the walls of the capsule, for example the third wall. 
     
     
         11 . The capsule of  claim 1 , wherein the sealing member has a laminate structure. 
     
     
         12 . The capsule of  claim 1 , wherein the fibrous and/or paperlike material encloses a radial edge of the capsule. 
     
     
         13 . The capsule of  claim 1 , comprising an exit filter for discharging beverage, wherein the fibrous and/or paperlike material and the exit filter are made in one piece. 
     
     
         14 . A system for preparing a predetermined quantity of beverage suitable for consumption using an extractable product, comprising:
 an exchangeable capsule, and   an apparatus comprising a fluid dispensing device for supplying an amount of a fluid, such as water, under pressure 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 third wall closing the circumferential first wall at a second, open, end opposite the second wall, the first, second and third wall enclosing an inner space comprising the beverage ingredients, wherein the capsule comprises a sealing member for achieving a sealing effect between the capsule and the beverage production device,   wherein the sealing member is made of a fibrous and/or paperlike material.   
     
     
         15 . A method for preparing a predetermined quantity of beverage suitable for consumption using an extractable product, comprising:
 providing an exchangeable capsule;   providing an apparatus comprising a receptacle for holding the exchangeable capsule;   arranging the exchangeable capsule in abutment with a support surface of the receptacle, wherein a fibrous and/or paperlike part of the capsule acts as a sealing member to achieve a fluid tight seal between the capsule and the beverage production device; and   supplying fluid under the pressure to the extractable product for preparing the beverage.
