A coffee machine has a filter holder receiving a filter cup adapted to hold a suspension of hot water and grounds. A generally horizontal filter forming a floor of the cup. The hot water infused by the grounds passes down through the filter as coffee. A side wall formed with a screwthread is provided on the cup underneath and generally perpendicular to the filter. A dispenser on the cup underneath the filter has an outlet directed generally perpendicularly at the side wall for spraying the coffee substantially perpendicularly against the screwthread and thereby generating froth.

The invention claimed is: 1. In combination with a coffee machine, a filter holder; a filter cup in the holder and adapted to hold a suspension of hot water and grounds; a generally horizontal filter forming a floor of the cup, whereby the hot water infused by the grounds passes down through the filter as coffee; a side wall formed with a screwthread on the cup underneath and generally perpendicular to the filter; and dispenser means on the cup underneath the filter having an outlet directed generally perpendicularly at the side wall for spraying the coffee substantially perpendicularly against the screwthread and thereby generating froth. 2. The combination according to claim 1, characterized in that it comprises an enhanced air passage defined between said cup and said filter holder. 3. The combination according to claim 2, characterized in that said enhanced passage comprises at least one groove at a free edge of said cup and a space between said cup and said filter holder. 4. The combination according to claim 1, further comprising a bent tab protruding from a portion of a free edge of said filter holder and inserted in a grooved seat of said cup. 5. The combination according to claim 1, characterized in that said dispenser means comprises a self-cleaning device. 6. The combination according to claim 5, characterized in that said self-cleaning device comprises a disk element having at its center a passage for housing a valve for closing said passage, the outlet being between said valve and said disk element. 7. The combination according to claim 6, characterized in that said valve has a disk which is mobile in said cup relative to and by means of the action of elastic means. 8. The combination according to claim 7, characterized in that it has an annular gasket between said disk element with said filtering wall. 9. The combination according to claim 8, characterized in that it comprises a bushing for attaching said disk element and said filter to said filter and forming the side wall. 10. The combination according to claim 9, characterized in that said bushing has a base and at least two outlet slits the coffee. 11. The combination according to claim 9, characterized in that the threads of said bushing are arranged in front of said outlet hole in a direction substantially perpendicular to said surface. 12. The combination according to claim 2, characterized in that it comprises at least one first chamber inside said filter holder, and a second chamber interposed between the filter of said filter holder and said dispenser means. 13. The combination according to claim 2, characterized in that said filter is connected to the inside of said filter holder, and a base of said filter holder has at least one opening for the passage of said coffee to said dispenser means. 14. The combination according to claim 2, characterized in that in correspondence with discharge openings of said coffee formed on a base of said cup, said cup has raised ribs for guiding said coffee. 15. The combination according to claim 14, characterized in that said ribs are arranged perpendicular to the flow of said coffee. 16. The combination according to claim 2, characterized in that said dispenser comprises at least one passage having at least one first substantially converging portion. 17. The combination according to claim 16, characterized in that at least said first portion of said passage is formed in an element made out of elastically ductile material. 18. The combination according to claim 16, characterized in that said passage has at least one second portion which is inclined with respect to said first portion. 19. The combination according to claim 2, characterized in that said dispenser means comprises a rigid element, connected to said filter holder, suitable for at least partially containing said elastically ductile element. 20. The combination according to claim 2, characterized in that at least one portion of said passage is bound by said rigid element. 21. The combination according to claim 2, characterized in that said elastically ductile element is removably connected between a base of said filter holder and said rigid element. 22. The combination according to claim 2, characterized in that said rigid element is removably connected on guides integral with said filter holder. 23. The combination according to claim 2, characterized in that it comprises a handle connected to said cup, said handle carrying a rotatable hook suitable for locking a portion of said filter holder against a corresponding portion of said cup when the grounds contained in said filter holder are discharged.
