A cartridge for extracting a beverage from an edible substance contained therein by means of a liquid under pressure, the cartridge comprising a main body having a cup portion and a lid portion. The base of said cup portion comprises a cup port defining a passage for the extracted beverage and protruding from the base outwardly with respect to the internal volume of the cartridge. Valve means are fixedly mounted on the internal surface of the cup port and are resiliently openable under pressure of the extracted beverage during a beverage extraction phase. The diameter of the open end of said cup port that is opposite to said cup base is sized so as to allow insertion of the valve means within the cup port. A safety cap is mounted on the external surface of the cup port and partially closes the external open end thereof.

What is claimed is: 1. A cartridge for extracting a beverage from an edible substance contained therein by means of a percolation fluid under pressure, the cartridge comprising: a main body comprising a cup portion and a lid portion, the cup portion comprising a base, a sidewall and a rim opposed to said base, the lid portion being fixedly attached to said rim of the cup portion so as to define an internal volume of said cartridge, the internal volume of said cartridge housing the edible substance, said lid portion comprising a lid port defining a first passage for said liquid under pressure and the base of said cup portion comprising a cup port defining a second passage for the extracted beverage, wherein said cup port protrudes from said base outwardly with respect to said internal volume, the cup port comprising valve means which are mounted within the cup port and which are resiliently openable under pressure of the extracted beverage during a beverage extraction phase, a safety cap which partially closes an external open end of said cup port being secured to the cup port at an external surface thereof, said cap comprises a base and a sidewall, the cap base of said cap partially closing said open end of the cup port and the cap sidewall being fixed to the external surface of the cup port, the base of said cap comprising an inner cylindrical wall which protrudes from the base of the cap and is coaxial to the cap sidewall, said inner cylindrical wall defining a first area and a second annular area of the base, the second annular area comprising at least one bottom aperture for allowing passage of the extracted beverage, the inner cylindrical wall being sized so as to abut against a support of the valve means and comprising at least one aperture for allowing passage of the extracted beverage from the inside to the outside of the volume surrounded by said inner cylindrical wall. 2. The cartridge of claim 1, wherein the valve means are fixedly mounted on the internal surface of the cup port by means of a snap-fit means, the diameter of the open end of said cup port that is opposite to said cup base being sized so as to allow insertion of said valve means within the cup port. 3. The cartridge of claim 1, wherein said valve means are normally closed when no pressure of said percolation fluid substances is applied, so as to insulate the internal volume of said cartridge from external environment when said cartridge is not installed into a beverage extraction machine. 4. The cartridge of claim 1, wherein said valve means are resiliently closable as soon as said pressure of percolation fluid substances drops due to a termination of said beverage extraction phase, so as to retain fluid residuals inside said internal volume. 5. The cartridge according to claim 2, wherein said valve means comprise a septum of a material selected from the group comprising rubbers, elastomers, flexible plastics, said septum comprising a through orifice that is normally closed, for insulating the internal volume of said cartridge from external environment and for retaining fluid residuals inside said internal volume when said beverage extraction has been terminated. 6. The cartridge according to claim 5, wherein said septum is made of a Styrene-Ethylene-Butylene-Styrene rubber. 7. The cartridge of claim 5, wherein said septum is sized so as to fluid-tight fit with the internal surface of the cup port. 8. The cartridge of claim 7, wherein said septum comprises annular ribs on its lateral surface, so as to provide a fluid-tight engagement with the internal surface of the cup port. 9. The cartridge of claim 5, wherein said septum is stacked on an annular support, which comprises said snap-fit means. 10. The cartridge of claim 2, wherein said snap-fit means comprise an annular protrusion which surrounds said valve means and which is engaged with a corresponding annular recess on the internal surface of said cup port. 11. The cartridge of claim 1, wherein said cap sidewall comprises a means for fixedly engaging with the external surface of the cup port. 12. The cartridge of claim 11, wherein said means for fixedly engaging the cap with the external surface of the cup port comprises at least one annular rib which engages with a corresponding annular rib that surrounds the external surface of said cup port. 13. The cartridge according to claim 1, wherein said at least one bottom aperture of said safety cap is partially surrounded by opposite vertical walls extending from said base at said second annular area. 14. The cartridge according to claim 1, wherein said base comprises a plurality of ridges directly formed thereon and protruding towards the internal volume of the cartridge, so as to define a plurality of concentric and radial channels for conveying the extracted beverage to the cup port. 15. The cartridge according to claim 1, wherein said cup port has a substantially cylindrical shape. 16. The cartridge according to claim 1, wherein said main body has a substantially cylindrical shape. 17. The cartridge according to claim 1, wherein said cartridge is made of any material selected from the group comprising: thermoplastics, aluminum, rubber, polylaminate plastics, thermosetting compositions and any combination thereof. 18. The cartridge according to claim 1, wherein said edible substance is selected from the group comprising: ground coffee, roasted ground coffee, instant coffee, tea, powdered chocolate, powdered milk, instant based brews or soups. 19. An extraction assembly to be mounted on beverage extraction machines, comprising a support connectable to a water outlet of a beverage extraction machine and a cartridge holder securable to said support and holding a cartridge according to claim 1.
