연합인증

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, 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.
