연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A cartridge 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 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. The cartridge further comprises a disc of porous material arranged between the filtering means and the base of the cup portion, 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.

The cartridge according to claim 1, wherein said cup port protrudes from the base of said cup portion outwardly with respect to said internal volume, so as to convey the extracted beverage into an external cup without contaminating any component of a beverage extraction machine. 3. The cartridge according to claim 1, wherein said lid port protrudes from said lid portion and has a substantially cylindrical shape. 4. The cartridge according to claim 1, wherein said lid port comprises a rubber seal having a central pierceable portion and a peripheral thicker portion for providing a radial fluid-tight seal when cartridge is installed into a beverage extraction machine. 5. The cartridge according to claim 1, wherein said main body has a substantially cylindrical shape and the cup base comprises a flange axially aligned with the sidewall of the cartridge and protruding outwardly with respect to the internal volume of the cartridge, so as to surround said cup port. 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, soups. 8. The cartridge according to claim 1, wherein the lid port or the cup port are of the female type, so as to be able to receive therein a water injection nozzle of a beverage extraction machine during a beverage extraction phase. 9. An extraction assembly to be mounted on beverage extraction machines, further comprising a support connectable to a water outlet of a beverage extraction machine and a cartridge holder securable to said support for holding a cartridge according to claim 1. 10. The extraction assembly of claim 9, 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. 11. 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. 12.
