The present invention relates to a capsule (1) for obtaining infusions, such as espresso, or beverages from water-soluble products, comprising an internal out flow duct (3) and being adapted to be hermetically sealed by means of a sealing element (10), wherein, by injecting water under pressure into the capsule (1), the sealing element (10) is lifted becoming detached from the top (7) of the internal out flow duct, opening the internal through hole (4) of the internal out flow duct (3) so that the infusion or beverage flows outwards through the internal through hole (4). Moreover, the present invention relates to a machine (17) for using capsules (1) according to the present invention and comprising housing means for housing at least one capsule during the dispensing phase and injection means (11) for injecting water under pressure into the capsule through the sidewall (2) of the capsule so as to obtain an infusion or beverage flowing out from the capsule through the internal through hole of the capsule.

1. Capsule injection moulded or thermoformed for obtaining a beverage from products placed therein, the capsule comprising an internal outflow duct comprising an internal through hole for an outflow of the infusion beverage through the internal through hole from the capsule and a differentially attached sealing element, the capsule comprising an upper surface having a closed perimeter for supporting said differentially attached sealing element so as to hermetically seal the capsule by means of said differentially attached sealing element, wherein a top of said internal outflow duct is substantially on the same level as said upper surface of the capsule and placed within the closed perimeter of the upper surface of the capsule so that said top supports said differentially attached sealing element when the capsule is sealed so as to seal said internal through hole and said differentially attached sealing element is welded to said upper surface of the capsule and said top of said internal outflow duct with differential detachment welding,wherein said differential detachment welding allows for lifting of said differential attached sealing element from said top of the internal outflow duct opening the internal through hole and at the same time keeping said differentially attached sealing element fixed to the closed perimeter of the upper surface of the capsule,whereby by injecting water under pressure into the capsule, said differentially attached sealing element is lifted becoming detached from the top of the internal outflow duct, opening said internal through hole of said internal outflow duct so that the beverage flows outwards through said internal through hole and said differentially attached sealing element remains welded to the closed perimeter of said upper surface. 2. Capsule according to claim 1, wherein said differentially attached sealing element comprises a peelable barrier film sealing membrane. 3. Capsule according to claim 1, wherein said internal outflow duct is substantially perpendicular to a bottom of the capsule. 4. Capsule according to claim 1, wherein said top of said internal outflow duct is flat. 5. Capsule according to claim 1, wherein the internal outflow duct has substantially a conical shape. 6. Capsule according to claim 1, wherein the internal outflow duct ends with a cylindrical portion. 7. Capsule according to claim 1, wherein the internal outflow duct comprises a terminal protruding portion protruding with respect to an adjacent portion of an external surface of a bottom of the capsule so as to hinder a flow along the external surface of the bottom of the capsule of the beverage flowing through said internal through hole. 8. Capsule according to claim 1, further comprising a lower filtering element applied in proximity to a bottom of the capsule so as to form a room for entry of water under pressure into the capsule. 9. Capsule according to claim 8, wherein said lower filtering element has a larger unfolded diameter than an inner diameter of the capsule so as to comprise an outer edge which is folded so as to adhere to a portion of an inner surface of the sidewall of the capsule. 10. Capsule according to claim 1, further comprising an upper filtering element applied between said top of said internal outflow duct and said differentially attached sealing element so that the beverage flows through said upper filtering element before lifting said differentially attached sealing element, and the beverage flows through said upper filtering element again before flowing out through said internal through hole. 11. Capsule according to claim 10, wherein said upper filtering element is welded to the upper surface of the capsule and to the top of the internal outflow duct and said differentially attached sealing element is welded to the upper surface of the capsule and to the top of the internal outflow duct so that a lower surface of said differentially attached sealing element adheres to an upper surface of said upper filtering element. 12. Capsule according to claim 10, wherein at least one or both of said lower filtering element and said upper filtering element comprises permeable and filtering thermosealable material. 13. Capsule according to claim 1, wherein the internal outflow duct comprises a terminal portion in proximity to a bottom of the capsule so as to form a protrusion inside the capsule. 14. Capsule according to claim 1, wherein, a filtering wheel having a hole with the top of the internal outflow duct placed within the hole and sitting on a circular groove of the capsule. 15. Capsule according to claim 1, wherein said internal through hole comprises a plurality of filtering holes in proximity to said top of said internal outflow duct. 16. Capsule according to claim 1, further comprising a flat surface, having a lower thickness than a thickness of a sidewall of the capsule, said flat surface formed on a portion of the sidewall of the capsule. 17. Capsule according to claim 1, wherein a bottom of the capsule comprises a strengthening structure for keeping said bottom substantially flat. 18. A capsule assembly for creating a beverage from a product placed within the capsule assembly when a fluid is injected into the capsule assembly under pressure comprising: a capsule having an open top with an upper surface and a bottom, said upper surface forming a perimeter;an internal outflow duct placed within the perimeter extending from the bottom to the open top of said capsule, said internal outflow duct having a flat top and a through hole;a product placed within said capsule; anda differentially attached sealing element, said differentially attached sealing element unreleasably fixed to the perimeter of the upper surface of said capsule and releasably attached to the flat top of said internal outflow duct covering and hermetically sealing the open top of said capsule,whereby said differentially attached sealing element is lifted from the flat top of said internal outflow duct so as to open the through hole when the fluid is injected into the capsule assembly under a predetermined pressure limited so that said differentially attached sealing element lifts off the flat top of said internal outflow duct yet remains fixed to the upper surface of said capsule. 19. A capsule assembly as in claim 18 further comprising: a filter placed between the open top and said differentially attached sealing element. 20. A capsule assembly as in claim 18 further comprising: a flat surface, placed in said capsule, having a reduced thickness relative to a thickness of said capsule,whereby said flat surface is adapted to receive an injection means for injecting the fluid into said capsule.
