There is disclosed a capsule for the preparation of a beverage using an extractable and/or dissolvable product and a quantity of hot and/or pressurized liquid. The capsule comprises a circumferential wall having on one end a bottom adapted to allow entrance of the liquid, and on an opposite end a lid closing said end of the circumferential wall. The circumferential wall, bottom and lid enclosing an inner space containing the product. At least one of the lid and/or bottom comprises at least one first portion and at least one second portion separated by at least one slit and having different moving mechanics when under pressure. At least a layer of tearable material covers said slit.

1. A capsule for the preparation of a beverage using an extractable and/or dissolvable product and a quantity of hot and/or pressurized liquid, comprising: a circumferential wall having on one end a bottom configured to allow entrance of the liquid, and on an opposite end a lid closing said end of the circumferential wall and configured to allow exit of the beverage, the circumferential wall, bottom and lid enclosing an inner space containing the product, at least one of the lid and bottom comprising at least one first portion and at least one second portion separated by at least one slit and having different moving mechanics when under pressure so that the first and second portions of the at least one of the lid and bottom will then move relatively at least at the position of the at least one slit, and comprising at least a layer of tearable material, made from a foil, permanently attached to at least a part of an inner or outer surface of the first and second portions, covering said slit and thereby fully closing the inner space, said at least a layer of tearable foil material being configured to be torn by the first and second portions moving relatively at the position of the at least one slit when under pressure. 2. The capsule according to claim 1, wherein the rigidity of the first and second portions is substantially greater than that of the layer of tearable material. 3. The capsule according to claim 1, wherein the first and second portions are configured such that the at least one first portion at least partly moves outwardly with respect to the at least one second portion which may remain substantially stationary when under pressure. 4. The capsule according to claim 1, wherein the at least first and second portions are partly connected to each other by at least one connection locally bridging the at least one slit. 5. The capsule according to claim 4, wherein the first and second portions are interconnected by a plurality of connections determining the relative movement of the first and second portions. 6. The capsule according to claim 4, wherein at least a part of the connections act as a plastically and/or elastically deformable hinge. 7. The capsule according to claim 1, wherein the at least one first portion comprises a plurality of first portions configured to move independently. 8. The capsule according to claim 1, wherein the at least one first portion comprises a plurality of interconnected first portions each having at least a connection to the at least one second portion. 9. The capsule according to claim 1, wherein the at least one first portion comprises one deformable first portion comprising a plurality of connections to the second portion which are spaced and distributed around the deformable first portion. 10. The capsule according to claim 1, wherein the at least one slit is serpentine shaped so as to enlarge its length and be distributed across the area of the lid or bottom. 11. The capsule according to claim 1, wherein the first and/or second portion are provided with at least a pointed area. 12. The capsule according to claim 1, wherein the first and second portions are made mainly of plastic material. 13. The capsule according to claim 1, wherein the at least a layer of tearable material, made from the foil, is part of a laminate also including a layer of tearable plastic material. 14. The capsule according to claim 13, wherein the thickness of at least one of the first and second portions is increased adjacent to the slits, by a rib formed along the circumference of the inner surface of the first portion and/or the outer surface of the second portion(s), and wherein at least one of the first and second portions includes a plurality of local protrusions distributed over the length of the at least one slit and protruding towards the other of the first and second portions, and extending the thickness of the first or second portion. 15. The capsule according to claim 1, wherein the relative movement between the first and second portions relative to the thickness of the first and second portions at the position of the at least one slit is so small that the first and second portions remain overlapping in their direction of movement in the opened position of the lid and/or bottom during use. 16. The capsule according to claim 1, wherein the lid and/or bottom is part of a separate element that is attached to the circumferential wall by welding. 17. The capsule according to claim 1, wherein the lid and/or bottom is part of a separate element that is attached to the circumferential wall by heat sealing. 18. The capsule according to claim 1, wherein the lid and/or bottom is part of a separate element that is attached to the circumferential wall by gluing. 19. The capsule according to claim 1, wherein the lid and/or bottom is part of a separate element that is attached to the circumferential wall by mechanically connecting.
