본 발명은 압력하에서 추출되도록 설계되고, 기호음료의 준비용 물질을 수용하며, 베이스와, 실질적인 절두체 원추형 측벽과, 상기 베이스보다 큰 직경의 원형립을 갖는 컵을 포함하는 밀봉 카트리지에 관한 것이다.The present invention relates to a sealing cartridge, which is designed to be extracted under pressure, contains a preparation material for a beverage and has a cup having a base, a substantially frustum conical sidewall, and a circular lip having a diameter larger than the base.

GE-PS 938, 617는, 2개의 격실을 형성하는 내부필터를 구비하며, 추출전 그 상부 및 하부면을 관통하는 시스템에 의해서 추출되도록 한 카트리지를 기술하고 있다. 이 카트리지의 단점은, 상기 면의 두께로 인하여 추출시의 완벽한 청결과 추출의 완료를 용이하게 실현하지 못하는 비교적 위험한 관통시스템의 사용을 필요로 한다는 점이다.GE-PS 938 and 617 describe cartridges that have an internal filter forming two compartments and are allowed to be extracted by a system that penetrates the upper and lower surfaces thereof prior to extraction. The disadvantage of this cartridge is that the thickness of the face requires the use of a relatively hazardous through system which does not readily realize complete cleanliness during extraction and completion of extraction.

무엇보다도, 압력하에서 추출되는 에스프레소형 커피의 분야에서 기호음료의 준비용 캡슐을 사용에는 다수의 이유, 즉 위생, 최적의 커피보존, 사용상의 편리, 얻어진 커피의 우수한 품질관리 및 추출조건의 양호한 재현성이 존재한다. 다수의 가용한 캡슐중에서, 실제로는 주입된 물의 압력의 영향하에서 개봉되는 밀봉 캡슐만이 상기한 요구를 만족시킨다. 이러한 종류의 캡슐은 그 개봉 시스템에 특징이 있다.Above all, in the field of espresso-type coffee to be extracted under pressure, the use of capsules for the preparation of favorite beverages has a number of reasons: hygiene, optimal coffee preservation, ease of use, good quality control of the obtained coffee and good reproducibility of extraction conditions. This exists. Of the many available capsules, only sealed capsules which actually open under the influence of the pressure of the injected water satisfy the above requirements. Capsules of this kind are characteristic of their opening system.

CH 605 293의 캡슐은 압력의 영향하에서 우선적으로 파열되는 약한 존(zone)을 갖는다. 이 해결책은 캡슐의 개봉이 정확하고 재현 가능하려면 사용된 재료들이 매우 정확하게 처리되어야 하므로 캡슐의 가격과 복잡성이 증가하는 단점이 있다.Capsules of CH 605 293 have weak zones that preferentially rupture under the influence of pressure. This solution has the disadvantage of increasing the cost and complexity of the capsule since the materials used must be processed very accurately in order for the opening of the capsule to be accurate and reproducible.

본 발명의 카트리지는 가격이 저렴하며, 제조가 용이하며, 기호음료, 특히 1 ∼ 15바아의 압력하에서 추출되는 에스프레소 커피의 준비물용으로 사용될 수 있다.The cartridge of the present invention is inexpensive, easy to manufacture, and can be used for the preparation of favorite beverages, in particular espresso coffee extracted under pressure of 1 to 15 bar.

본 발명은 압력하에서 추출되도록 설계되고, 기호음료의 준비용 물질을 수용하며, 베이스와, 실질적인 절두체 원추형 측벽고, 상기 베이스 보다 큰 직경의 원형립을 갖는 컵을 포함하는 밀봉 카트리지에 관한 것으로, 이 카트리지는 알루미늄, 알루미늄/플라스틱 복합제, 알루미늄/플라스틱/종이 복합제, 순수 플라스틱 또는 다층 플라스틱으로 구성되는 군에서 선택되는 산소 불침투성의 가요성 재료로 구성되면서 상기 컵의 립의 외연에 용착되는 커버를 포함하고, 상기 커버 또는 베이스는 추출 과정의 개시점에서 추출액의 압력의 영향하에서만 파열된다.The present invention relates to a sealing cartridge, which is designed to be extracted under pressure, contains a material for preparing a beverage and includes a cup having a base, a substantially frustum conical sidewall, and a circular lip having a diameter larger than the base. The cartridge comprises a cover that is welded to the outer edge of the lip of the cup, consisting of an oxygen impermeable flexible material selected from the group consisting of aluminum, aluminum / plastic composite, aluminum / plastic / paper composite, pure plastic, or multilayer plastic. The cover or base ruptures only under the influence of the pressure of the extract at the beginning of the extraction process.

이 카트리지의 장점은 엄밀한 의미에서 필터 또는 약한 존을 갖지 않는다는 것이다.The advantage of this cartridge is that it does not have a filter or weak zone in the strict sense.

본 발명의 카트리지는 유럽 특허출원 제91 107 462.3호에 따른 방법과 시스템에 의해서 추출될 수 있다. 이 특허출원의 추출시스템은 간이 캡슐이 양호한 조건하에서 추출되도록 한다. 캡슐을 추출하는데에는 추출액의 영향하에서 파열되는 컵의 베이스 또는 커버가 있다. 커버일 경우, 추출 시스템내로 카트리지가 도입되는 동안 물주입기에 의해서 컵의 베이스가 먼저 개봉되며, 압력의 증가시 커버가 파열되고, 그리고 사용후 카트리지는 용이하게 제거될 수 있고, 최소의 찌꺼기 커피 그라운드 또는 포장 재료를 남기면서 유지된다.The cartridge of the invention can be extracted by a method and a system according to EP 91 107 462.3. This patented extraction system allows simple capsules to be extracted under good conditions. Extracting capsules includes the base or cover of the cup that is ruptured under the influence of the extract. In the case of a cover, the base of the cup is first opened by the water injector while the cartridge is introduced into the extraction system, the cover ruptures upon increase in pressure, and after use the cartridge can be easily removed and minimal ground coffee ground Or is left while leaving the packaging material.

상기 커버는 보통 열 접착에 의해서 컵의 외연에 용착되며, 용착되는 부분은 그 반대면상에서 용착래커(welding lacquer)를 포함한다. 컵의 하부립은 또한 주름 형성(crimping)을 위하여 커버상으로 뒤로 접혀질 수 있다. 자체만의 또는 주름 형성과 결합된 용착은, 카트리지가 추출공정시 15바에 달하는 압력을 견딜 수 있도록 허용한다.The cover is usually deposited on the outer edge of the cup by thermal bonding, and the welded portion includes a welding lacquer on the opposite side. The lower lip of the cup can also be folded back onto the cover for crimping. The welding itself or in combination with pleat formation allows the cartridge to withstand up to 15 bars of pressure during the extraction process.

카트리지에는 기호음료의 준비용 물질이 채워진다. 이 물질은 로우스트 및 그라운드 커피(ground coffee)가 바람직하지만, 또한 차, 가용성 커피, 그라운드 커피와 가용성 커피의 혼합물, 초콜렛 기재물 또는 그 이외의 탈수된 식용물질 일 수 있다.The cartridge is filled with a substance for preparing a beverage.
