The invention relates to a capsule and a device for preparing an infusion beverage, such as coffee, tea, or milk beverages. The capsule comprises two parallel extending wall sections, which are connected to each other by a sealing connection. A pressurized liquid or gaseous medium can be conducted through an access to the sealing connection of the capsule with the aid of a supply line in a holder of the device such that the sealing connection is partially undone. As a result, an opening is produced in the capsule. An infusion fluid can be conducted through the opening, wherein the fluid can then become mixed with a powder or granules present in the capsule into an infusion beverage. The infusion beverage can be discharged through a further opening.

1. A capsule for infusion beverages, comprising two parallel wall portions which are connected at least in part by a sealing connection, whereas the sealing connection has a region to which there is an access from the outside, so that at least a part of the sealing connection can be undone by introducing a pressurized liquid or gaseous medium through this access, to create an opening for introducing an infusion liquid into the capsule, wherein said access is arranged to run substantially perpendicular to the parallel main faces of the two wall portions in the region of the sealing connection. 2. The capsule as claimed in claim 1, the capsule being assembled from two parts, the two parts being connected by the sealing connection. 3. The capsule as claimed in claim 1, whereas a first of the wall portions is dimensionally stable in the aforementioned region of the sealing connection and the second of the wall portions is flexible in this region. 4. The capsule as claimed in claim 3, whereas the first, dimensionally stable wall portion is made of a flexible material which is reinforced with the aid of a second, dimensionally stable layer. 5. The capsule as claimed in claim 4, whereas the first wall portion pertains to the wall of a dimensionally stable container and the second wall portion pertains to the wall of a flexible, substantially flat foil. 6. The capsule as claimed in claim 3, whereas the first wall portion pertains to the wall of a dimensionally stable container and the second wall portion pertains to the wall of a flexible, substantially flat foil. 7. The capsule as claimed in claim 6, the container and the foil being substantially rotationally symmetrical and the wall portions a peripheral flange, so that the sealing connection runs annularly. 8. A capsule for infusion beverages, comprising two parallel wall portions which are connected at least in part by a sealing connection, whereas the sealing connection has a region to which there is an access from the outside, so that at least a part of the sealing connection can be undone by introducing a pressurized liquid or gaseous medium through this access, to create an opening for introducing an infusion liquid into the capsule, whereas a first of the wall portions is dimensionally stable in the aforementioned region of the sealing connection and the second of the wall portions is flexible in this region and wherein the access to the sealing connection is provided by at least one aperture in the dimensionally stable wall portion of the capsule. 9. The capsule as claimed in claim 8, whereas a plurality of set-apart apertures are present in the dimensionally stable wall portion of the capsule. 10. A device for preparing an infusion beverage using comprising a capsule, the capsule comprises two parallel wall portions which are connected at least in part by a sealing connection, whereas the sealing connection has a region to which there is an access from the outside, so that at least a part of the sealing connection can be undone by introducing a pressurized liquid or gaseous medium through this access, and a holder for the capsule and at least one feed line for a pressurized liquid or gaseous medium, the feed line being embodied in such a way that, when the capsule is inserted into the holder of the device, the medium is guided through the access of the capsule to a sealing connection between the two parallel wall portions of the capsule, allowing at least a part of the sealing connection to be undone, an opening being created for introducing an infusion liquid into the capsule. 11. The device as claimed in claim 10, whereas the holder is embodied in such a way that the capsule can be at least partially held by the wall portions which are connected at least in part by the sealing connection. 12. The device as claimed in claim 10, comprising a receiving space in which the wall portions of the capsule can be at least partly received, the wall portions being connected by the sealing connection, the receiving space being embodied in such a way that the parallel wall portions are enclosed on both sides in an outer region in such a way that detachment of the sealing connection is prevented outward and allowed inward. 13. A method for preparing an infusion beverage using a capsule, where the capsule comprises two parallel wall portions which are connected at least in part by a sealing connection, whereas the sealing connection has a region to which there is an access from the outside, the method comprises supplying a pressurized liquid or gaseous medium through the access of the capsule to the sealing connection between the two parallel wall portions of the capsule, as a result of which at least a part of the sealing connection is undone, so that an opening is created for introducing an infusion liquid into the capsule. 14. The method as claimed in claim 13, whereas the pressurized liquid or gaseous medium is supplied at a pressure in the range of from 10 bar to 20 bar, in particular from 13 bar to 16 bar. 15. The method as claimed in claim 14, whereas the medium for undoing the sealing connection is identical to the infusion liquid used for preparing the infusion beverage. 16. The method as claimed in claim 13, whereas the medium for undoing the sealing connection is identical to the infusion liquid used for preparing the infusion beverage.
