Integrated cartridge for extracting a beverage from a particulate substance

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 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 lid port defining a first passage for percolation fluid substances, the base of said cup portion comprising a cup port defining a second passage for percolation fluid substances,
• further comprising a disc of porous material arranged between said filtering means and the base of said cup portion, so as to support said filtering means and said particulate substance and to define a fine canalization between said filtering means and said cup port,
• wherein at least one of said cup port or said lid port comprises fluid flow hurdles formed on its internal surface or mounted therein, for breaking direct fluid flow passing through said cup port or said lid port, respectively.

• said lid portion comprising a lid port defining a first passage for percolation fluid substances, the base of said cup portion comprising a cup port defining a second passage for percolation fluid substances,
• further comprising a disc of porous material arranged between said filtering means and the base of said cup portion, so as to support said filtering means and said particulate substance and to define a fine canalization between said filtering means and said cup port,
• wherein said lid portion comprises a plurality of ridges directly formed on its inner side and protruding towards the internal volume of the cartridge, so as to support said filtering means and said particulate substance and to define a fine canalization between said filtering means and said lid port.

• wherein said cup port comprises valve means resiliently openable under pressure of said percolation fluid substances so as to allow passage of said percolation fluid substances through said cup port,
• wherein said valve means comprise a pad or disc of a resilient material selected from the group comprising rubbers, elastomers, flexible plastics, said pad comprising a through slit 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, and
• wherein said pad or disc comprises surface ribs for supporting said particulate substance and said filtering means and for allowing fluid passage therebetween.
