A cartridge, particularly for espresso coffee machines, for extracting a beverage from a particulate substance contained therein by means of water under pressure is provided. The cartridge comprises a main body with a cup portion and a lid portion. The cup portion comprises a base, a sidewall and a rim opposed to the base, while the lid portion is fixedly attached to the rim of the cup portion so as to define an internal volume of the cartridge. The internal volume of the cartridge houses the particulate substance comprised within filtering means for retaining the particulate substance and for percolating fluid substances therethrough. The lid portion comprises a normally closed lid port defining a first passage for percolation fluid substances when it is opened. The cartridge further comprises a tappet arranged inside the internal volume so as to pierce the base when a pressure is applied to the base towards the internal volume, thus opening a normally closed cup port.

1. A cartridge, particularly for espresso coffee machines, for extracting a beverage from a particulate substance contained therein by means of water 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 particulate substance comprised within filtering means for retaining said particulate substance and for percolating fluid substances therethrough,said lid portion comprising a normally closed lid port defining a first passage for percolation fluid substances when it is opened,further comprising a tappet arranged inside said internal volume so as to pierce said base when a pressure is applied externally to said base towards said internal volume, thus opening a normally closed cup port of said base. 2. The cartridge according to claim 1, wherein the base of said cup portion forms a substantially conical hollow volume with said particulate substance and said filtering means, said conical hollow volume housing said tappet that holds on said normally closed cup port. 3. The cartridge according to claim 1, wherein said tappet comprises a disc-like supporting portion on which said particulate substance and said filtering means lean and a spike protruding out from the supporting portion on its side opposite to said particulate substance and said filtering means, so that said tappet holds on said cup port when it is closed and said spike pierces said cup port when said pressure is applied. 4. The cartridge according to claim 3, wherein the bottom side of said tappet comprises radial ribs protruding towards the base of said cup portion, for keeping a gap between said base and said tappet should said base buckle due to said pressure. 5. The cartridge according to claim 1, wherein said main body has a substantially cylindrical shape with a conically protruding base. 6. The cartridge according to claim 1, wherein it is made of any material selected from the following: thermoplastics, aluminum, rubber, polylaminate plastics, thermosetting compositions, and any combination thereof. 7. The cartridge according to claim 1, wherein said particulate substance is selected from the group comprising: ground coffee, roasted ground coffee, instant coffee, tea, powdered chocolate, powdered milk, instant based brews or soups. 8. 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, said cartridge holder holding a cartridge according to claim 1. 9. The extraction assembly of claim 8, wherein said cartridge holder has an internal shape substantially corresponding to the external shape of said cartridge so that said cartridge can tightly fit within said holder. 10. A cartridge, particularly for espresso coffee machines, for extracting a beverage from a particulate substance contained therein by means of water 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 particulate substance comprised within filtering means for retaining said particulate substance and for percolating fluid substances therethrough,said lid portion comprising a normally closed lid port defining a first passage for percolation fluid substances when it is opened,further comprising a tappet arranged inside said internal volume so as to pierce said base when a pressure is applied to said base towards said internal volume, thus opening a normally closed cup port;wherein said tappet comprises a disc-like supporting portion on which said particulate substance and said filtering means lean and a spike protruding out from the supporting portion on its side opposite to said particulate substance and said filtering means, so that said tappet holds on said cup port when it is closed and said spike pierces said cup port when said pressure is applied; andwherein said supporting portion comprises a plurality of through holes evenly distributed on its top surface. 11. An extraction assembly to be mounted on beverage extraction machines, characterized in that it comprises: a support connectable to a water outlet of a beverage extraction machine; anda bayonet cartridge holder securable to said support; anda cartridge for extracting a beverage from a particulate substance, said cartridge being held inside said bayonet cartridge holder;said 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 particulate substance comprised within filtering means for retaining said particulate substance and for percolating fluid substances therethrough,said lid portion comprising a normally closed lid port defining a first passage for percolation fluid substances when it is opened,a tappet being arranged inside said internal volume so as to pierce said base when a pressure is applied externally to said base towards said internal volume, thus opening a normally closed cup port of said base,said bayonet cartridge holder being internally shaped so as to apply said external pressure to the base of said cartridge towards said internal volume when the bayonet cartridge holder is secured by rotation thereof to said support.
