Abstract
A cartridge 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 the base, the lid portion being 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 housing the particulate substance comprised within filtering means for retaining the particulate substance and for percolating fluid substances therethrough, the lid portion comprising a lid port defining a first passage for percolation fluid substances, the base of the cup portion comprising a cup port defining a second passage for percolation fluid substances, wherein the base comprises a plurality of ridges directly formed thereon and protruding towards the internal volume of the cartridge, so as to support the filtering means and the particulate substance and to define a fine canalization between the filtering means and the cup port.

82. 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; and
a cartridge holder securable to said support for holding a cartridge for extracting a beverage from a particulate substance 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 to said base towards said internal volume, thus opening a normally closed cup port, said cartridge holder being internally shaped so as to apply said pressure to the base of said cartridge towards said internal volume when the cartridge holder is secured to said support.
