1. A capsule for preparing beverages, comprising: a housing at least partially filled with a substance to be extracted and/or dissolved, wherein the housing is provided with a supply side for pressing a liquid such as water into the capsule, and with a discharge side located a distance from the supply side for discharging liquid containing extract and/or dissolved substance and guided through the capsule, wherein the supply side and/or the discharge side of the housing is initially sealed by a foil;a laterally protruding engaging edge connected to the housing to enable clamping of the capsule in a capsule holder of a device for preparing beverages; andat least one annular resilient sealing element arranged at least on the engaging edge and/or the housing for sealing a space between the capsule holder and the capsule during clamping of the capsule in the capsule holder, wherein at least one absorption cavity is formed by an annularly extending groove and is wholly enclosed by at least the sealing element. 2. The capsule as claimed in claim 1, wherein the at least one absorption cavity is wholly enclosed by the sealing element and the engaging edge and/or the housing. 3. The capsule as claimed in claim 1, wherein a part of the sealing element enclosing the at least one absorption cavity is provided with at least one weakening zone. 4. The capsule as claimed in claim 1, wherein the at least one absorption cavity is a plurality of absorption cavities and the sealing element at least partially encloses some of the plurality of absorption cavities. 5. The capsule as claimed in claim 1, wherein an absorption cavity of the at least one absorption cavity is filled with air. 6. The capsule as claimed in claim 5, wherein the at least one absorption cavity comprises at least two absorption cavities at least one of said absorption cavities which is in communication with the atmosphere surrounding the capsule. 7. The capsule as claimed in claim 1, wherein an absorption cavity of the at least one absorption cavity is at least partially filled with liquid and/or gel. 8. The capsule as claimed in claim 1, wherein an absorption cavity of the at least one absorption cavity is given a bubble-like form. 9. The capsule as claimed in claim 1, wherein the resilient sealing element is manufactured at least partially from a porous material. 10. The capsule as claimed in claim 1, wherein a side of the sealing element remote from the engaging edge is provided with at least one protruding edge. 11. The capsule as claimed in claim 10, wherein a side of the sealing element remote from the engaging edge is provided with a plurality of protruding edges. 12. The capsule as claimed in claim 11, wherein the protruding edges are oriented concentrically relative to each other. 13. The capsule as claimed in claim 1, wherein the sealing element forms at least a part of the engaging edge. 14. The capsule as claimed in claim 1, wherein the sealing element forms at least a part of the housing. 15. The capsule as claimed in claim 1, wherein the sealing element is at least partially manufactured from a thermoplastic polyolefin (TPO). 16. The capsule as claimed in claim 15, wherein the sealing element comprises a composition of polyolefins, the composition comprising: polypropylene and an elastomeric copolymer comprising units of ethylene and units of an α-olefin. 17. The capsule as claimed in claim 15, wherein the sealing element is at least partially manufactured from polypropylene. 18. The capsule as claimed in claim 1, wherein the sealing element is connected non-releasably to another part of the capsule. 19. The capsule as claimed in claim 18, wherein the sealing element is welded to another part of the capsule. 20. The capsule as claimed in claim 1, wherein the sealing element is arranged releasably on another part of the housing. 21. The capsule as claimed in claim 1 wherein foil is adapted as a filter. 22. The capsule as claimed in claim 1, wherein the foil initially seals the housing substantially tightly, such that the foil deforms under pressure. 23. The capsule as claimed in claim 22, wherein the capsule comprises a perforation structure coupled substantially rigidly to the engaging edge and/or the housing, which perforation structure is provided with at least one perforation element facing toward the foil for perforating the foil, and which perforation structure is positioned substantially on a side of the foil remote from the housing, wherein perforation of the foil is caused by deformation of the foil during pressing of the liquid through the capsule. 24. The capsule as claimed in claim 23, wherein the perforation structure is positioned at least partially in a volume enclosed by the housing. 25. The capsule as claimed in claim 23, wherein the capsule comprises a perforation structure coupled to the engaging edge and/or the housing and provided with at least one perforation element facing toward the foil, which perforation structure is positioned substantially on a side of the foil remote from the housing, and which perforation structure is displaceable from a first position, in which the foil is substantially intact, to a second position in which the at least one perforation element perforates the foil, whereby discharge of liquid from the capsule is possible. 26. The capsule as claimed in claim 25, wherein the perforation structure is initially connected in the first position via at least one breakable connection to the engaging edge, wherein the perforation structure is displaceable to the second position by breaking the connection between the perforation structure and the engaging edge. 27. The capsule as claimed in claim 26, wherein the at least one breakable connection is rigid and resists bending by light hand pressure. 28. The capsule as claimed in claim 26, wherein the perforation structure is initially positioned such that the connection between the engaging edge and the perforation structure will be broken during clamping of the capsule in the device. 29. An assembly of a capsule as claimed in claim 1 with a device for preparing beverages, which device comprises a capsule holder for receiving the capsule. 30. The assembly as claimed in claim 29, wherein the capsule holder comprises a plurality of holder parts which are mutually displaceable between an opened state, in which the capsule can be placed in the capsule holder, and a closed state in which the engaging edge and the sealing element of the capsule are clamped substantially liquid-tightly by the holder parts.
