Description
本発明は、圧力をかけて抽出されるように設計された可撓性密封カートリッジであって、焙煎されて挽かれたコーヒー、インスタント・コーヒー、挽かれたコーヒーとインスタント・コーヒーとの混合物、チョコレート製品、または他の何らかの脱水された消費可能な物質から選択される飲料を調製するための物質が入れられており、間に物質のための空間を残して周辺部の周りで1つに溶着された、円形、楕円形、または多角形の第1および第2シートからなり、第1シートが、濾紙、不織布、および半剛性材料から選択される材料製で、第2シートが、濾紙、不織布、および複合材から選択される材料製であるカートリッジに関する。 The present invention is a flexible sealed cartridge designed to be extracted under pressure, comprising roasted and ground coffee, instant coffee, a mixture of ground and instant coffee, Contains a substance to prepare a beverage selected from chocolate products, or some other dehydrated consumable substance, and welds together around the periphery leaving a space for the substance in between Made of circular, oval or polygonal first and second sheets, wherein the first sheet is made of a material selected from filter paper, nonwoven fabric, and semi-rigid material, and the second sheet is filter paper, nonwoven fabric And a cartridge made of a material selected from composites.
市場にはすでに、圧力上昇の効果によって開く密封カートリッジがある。欧州特許EP512468は、そのようなカートリッジに関するものであるが、それらのカートリッジには、カートリッジの上部に穴を開けるための先の尖った抽出デバイスと、カートリッジの底部を開かせてコーヒーをカップへと流すための陥凹要素および***要素とを必要とするという問題がある。また、欧州特許EP272432の主題をなすものなど、濾紙製のカートリッジもあるが、それらのカートリッジには、大きな圧力上昇がなく、水があまりにも急速にコーヒー層上へと流れるので、コーヒーに良い量の泡が残らないという問題がある。 There are already sealed cartridges on the market that open due to the effects of pressure rise. European Patent EP 51 468 relates to such cartridges, which include a pointed brewing device for perforating the top of the cartridge and a bottom of the cartridge to open the coffee into a cup. There is the problem of requiring recessed and raised elements for flow. There are also filter paper cartridges, such as those that are the subject of European patent EP272432, but these cartridges do not have a large pressure rise and the water flows too quickly onto the coffee layer, so it is good for coffee. There is a problem that no bubbles remain.
本発明の目的は、抽出に、あまり高価でない、より単純なデバイスを必要とし、それでもなお、良い量で良質の泡が残っているコーヒーを与えるカートリッジをユーザに提供することである。 It is an object of the present invention to provide a user with a cartridge that provides a coffee that requires a less expensive, simpler device for extraction, yet still leaves good quality foam in good quality.
本発明は、請求項1のプリアンブルによる可撓性密封カートリッジにおいて、第1シートが、大気圧で、あるいは穴あけ手段で穴をあけることによって水を通過させるようなものであり、第2シートが、前記カートリッジからの抽出時に0.1〜3barの過圧に達したときにだけ水を通過させるようなものである。
The flexible sealing cartridge according to the preamble of
したがって、本発明の目的は、抽出すべき物質を取り囲む材料、すなわち第1シートと第2シートとが同質でないカートリッジを提供することである。この第2シートは、水がコーヒー豆を濡らして膨張させる時間ができるように水を保持しなければならず、この遅延効果がコーヒーの良好な抽出と良好な泡とを与える。遅延効果の持続時間は、給水ポンプによって決まり、すなわち、カートリッジ内の圧力上昇がどのようなものであるかによって決まる。通常、1〜3barの過圧についての遅延効果は、1秒程度である。それでもやはり、圧力上昇の理由から、言うまでもなく、抽出時にはカートリッジの第2シートの下に支持プレートを設ける必要がある。 The object of the present invention is therefore to provide a cartridge in which the material surrounding the substance to be extracted, i.e. the first sheet and the second sheet, are not homogeneous. This second sheet must retain water so that it has time to wet the coffee beans and allow them to swell, and this retarding effect provides good extraction of coffee and good foam. The duration of the delay effect depends on the feed pump, i.e. what the pressure rise in the cartridge is. Usually, the delay effect for an overpressure of 1 to 3 bar is about 1 second. Nevertheless, for reasons of pressure increase, it goes without saying that it is necessary to provide a support plate under the second sheet of the cartridge during extraction.
カートリッジ内にコーヒーが入っている場合、これは、焙煎されて挽かれたコーヒーが、単純にカートリッジ内に置かれたもの、または圧縮されたものである。そのコーヒーの量は、5〜10gの様々な量にすることができる。 If there is coffee in the cartridge, this is simply roasted and ground coffee placed in the cartridge or compressed. The amount of coffee can vary from 5 to 10 g.
第1シートが濾紙または不織布製の場合、水は、単純に重力によってカートリッジ内のコーヒー層内へと流れる。他方、第1シートが半剛性材料製の場合、前記第1シートを開かせるのに、たとえば欧州特許EP242556によるデバイスを備えた穴あけ手段が必要である。濾紙の場合、秤量15〜30g/m2、厚さ0.1〜1mmの紙が使用される。不織布の場合、秤量20〜100g/m2の、ポリプロピレン、ポリエチレン、ポリエチレンテレフタレート、またはポリウレタンが使用される。半剛性材料の場合、厚さ20〜100ミクロンのアルミニウム、任意でEVOHやPVDCなどの酸素バリア層を備えた純粋または多層プラスチック、厚紙、アルミニウム、プラスチック、ボール紙などの多層フィルム、任意でEVOHやPVDCなどの酸素バリア層を備えたプラスチックが使用される。 If the first sheet is made of filter paper or non-woven fabric, the water simply flows by gravity into the coffee layer in the cartridge. On the other hand, if the first sheet is made of a semi-rigid material, a drilling means with a device, for example according to European patent EP 242556, is required to open the first sheet. In the case of filter paper, paper having a weight of 15 to 30 g / m 2 and a thickness of 0.1 to 1 mm is used. In the case of a nonwoven fabric, polypropylene, polyethylene, polyethylene terephthalate, or polyurethane having a weight of 20 to 100 g / m 2 is used. For semi-rigid materials, aluminum with a thickness of 20-100 microns, optionally a pure or multilayer plastic with an oxygen barrier layer such as EVOH or PVDC, multilayer film such as cardboard, aluminum, plastic, cardboard, optionally EVOH or A plastic with an oxygen barrier layer such as PVDC is used.
第1の実施例では、第2シートが、カートリッジ内の圧力が0.1〜3barの値に達したときに開く脆弱な領域を含む。「脆弱な領域」という表現は、予め切れ目が付けられた領域を意味するものと理解される。これらもやはり、濾紙、不織布、またはさらにプラスチック・シートにすることができる。 In the first embodiment, the second sheet includes a fragile area that opens when the pressure in the cartridge reaches a value of 0.1 to 3 bar. The expression “vulnerable area” is understood to mean a previously cut area. Again, these can be filter paper, non-woven fabrics, or even plastic sheets.
第2の実施例では、第2シートが、圧力が0.1〜3barに達したときにだけ水を通過させる、十分に目の細かい濾紙または不織布製である。「十分に目の細かい」という表現は、空気または水の透過性が低いことを意味するものと理解される。 In a second example, the second sheet is made of sufficiently fine filter paper or nonwoven that allows water to pass only when the pressure reaches 0.1-3 bar. The expression “sufficiently fine” is understood to mean a low permeability of air or water.
これら2つの実施例では、第1シートが、濾紙および不織布で作製され、あるいは半剛性材料で作製される。いずれの場合にも、カートリッジが酸素バリアを形成する材料内には包装されないので、カートリッジに外装を設けなければならない。 In these two examples, the first sheet is made of filter paper and non-woven fabric, or made of semi-rigid material. In either case, the cartridge must be provided with an exterior since it is not packaged in the material that forms the oxygen barrier.
第3の実施例では、第2シートが、アルミニウム/プラスチック複合材である。「アルミニウム/プラスチック複合材」という表現は、予め切れ目が付けられたプラスチック・シートをその上に備えたアルミニウム・シートを意味するものと理解される。この事例では、第1シートが濾紙または不織布の場合、外装が必要である。他方、第1シートが半剛性材料製の場合、アルミニウム/プラスチック層が酸素の透過を妨げるので、外装は必ずしも必要でない。 In the third embodiment, the second sheet is an aluminum / plastic composite. The expression “aluminum / plastic composite” is understood to mean an aluminum sheet with a pre-scored plastic sheet thereon. In this case, when the first sheet is filter paper or non-woven fabric, an exterior is necessary. On the other hand, if the first sheet is made of a semi-rigid material, the exterior is not necessarily required because the aluminum / plastic layer prevents oxygen permeation.
第4の実施例では、第2シートが、取り外されるカバーと、圧力が0.1〜3barのときに水を通過させる濾紙または不織布製の層とで構成される。後者の場合にも、外装は必ずしも必要でない。 In the fourth embodiment, the second sheet is composed of a cover to be removed and a filter paper or non-woven fabric layer that allows water to pass through when the pressure is 0.1 to 3 bar. Even in the latter case, the exterior is not necessarily required.
第5の実施例では、第2シートが、ラッカー層でコーティングされた濾紙または不織布製である。 In a fifth embodiment, the second sheet is made of filter paper or nonwoven coated with a lacquer layer.
第6の実施例では、第2シートが、熱処理された不織布製である。 In the sixth embodiment, the second sheet is made of a heat-treated nonwoven fabric.
以後は、図面に即して説明する。 Hereinafter, description will be made with reference to the drawings.
図1によるカートリッジ(1)では、焙煎されて挽かれたコーヒー(2)が、濾紙製の第1シート(3)と、やはり濾紙製の第2シート(4)との間に包装されている。2枚のシートは、前記カートリッジの周辺部の周り(5)で1体に溶着されている。第1シートは、大気圧で水を通過させるが、やはり濾紙製の第2シートは、脆弱な領域を含んでおり、抽出時には、コーヒーが初めに十分に濡らされ、それから十分に膨らみ、前記カートリッジ内の過圧が1bar程度に達したときにだけ液体のコーヒーが流れ出る。したがって、コーヒーの通過に対する遅延効果があり、それが、良い量で上質の泡が残っているコーヒーをもたらす。このカートリッジによって、先の尖ったものなしに、単純にカートリッジを十分に密封して収容し、抽出を達成する手段を備えた、抽出システムを使用することが可能になる。 In the cartridge (1) according to FIG. 1, the roasted and ground coffee (2) is packed between a first sheet (3) made of filter paper and a second sheet (4) also made of filter paper. Yes. The two sheets are welded together around the periphery of the cartridge (5). The first sheet allows water to pass at atmospheric pressure, but the second sheet, also made of filter paper, contains a fragile area, and during extraction, the coffee is initially fully wetted and then fully swelled, the cartridge Liquid coffee flows out only when the internal overpressure reaches about 1 bar. Therefore, there is a delay effect on the passage of coffee, which results in a coffee with a good amount of fine foam remaining. This cartridge makes it possible to use an extraction system that simply has a well-sealed cartridge and is equipped with means to effect extraction without a pointed object.
図2は、焙煎されて挽かれたコーヒー(7)が2枚の不織布シート間に包装されているカートリッジ(6)を示す。第1シート(8)は、大気圧で水を通過させる不織布のシートである。第2シート(9)は、カートリッジ内の過圧が1barに達したときに水を通過させる、目の細かい不織布製である。2枚のシートは、それらの周辺部の周り(10)で1つに接合されている。前述のカートリッジに関するのと同一の抽出システムを使用することができる。 FIG. 2 shows a cartridge (6) in which roasted and ground coffee (7) is wrapped between two nonwoven sheets. The first sheet (8) is a non-woven sheet that allows water to pass through at atmospheric pressure. The second sheet (9) is made of a fine non-woven fabric that allows water to pass through when the overpressure in the cartridge reaches 1 bar. The two sheets are joined together around their periphery (10). The same extraction system as for the aforementioned cartridge can be used.
図3の場合、カートリッジ(11)は、アルミニウムの半剛性材料製の第1シート(12)と、濾紙製の第2シート(13)とを含む。焙煎されて挽かれたコーヒー(14)が、これら2枚のシートの間に置かれている。これらのシートは、その周辺部(15)の周りで接合されている。このカートリッジから抽出するには、第1シートに穴を開けるための針、たとえば欧州特許EP242556の主題をなすものが必要である。濾紙製のシートは、抽出時にカートリッジ内の過圧が1bar程度に達したときにコーヒーを通過させる。 In the case of FIG. 3, the cartridge (11) includes a first sheet (12) made of an aluminum semi-rigid material and a second sheet (13) made of filter paper. Roasted and ground coffee (14) is placed between these two sheets. These sheets are joined around their periphery (15). Extraction from this cartridge requires a needle for piercing the first sheet, for example the subject of European patent EP 242556. The filter paper sheet allows coffee to pass when the overpressure in the cartridge reaches about 1 bar during extraction.
図4は、第3の実施例によるカートリッジ(16)を示す。焙煎されて挽かれたコーヒー(17)は、アルミニウム製の剛性の第1シート(18)と、アルミニウム・シート(19)および予め切れ目が付けられたプラスチック・シート(20)から形成される複合材との間に包装されている。シート(19)および(20)は、(21)のところでシート(18)に接合されている。シート(18)に穴をあけるには、前述の欧州特許に記載の針が必要である。シート(19)の厚さには機械的強度がなく、酸素バリアの働きをする。シート(20)は、カートリッジ内の過圧が1barに達したときに開く。この解決策の利益は、外装が必要ないことである。 FIG. 4 shows a cartridge (16) according to a third embodiment. Roasted and ground coffee (17) is a composite formed from an aluminum rigid first sheet (18), an aluminum sheet (19) and a pre-scored plastic sheet (20). Wrapped between materials. Sheets (19) and (20) are joined to sheet (18) at (21). In order to make a hole in the sheet (18), the needle described in the aforementioned European patent is required. The thickness of the sheet (19) has no mechanical strength and acts as an oxygen barrier. The sheet (20) opens when the overpressure in the cartridge reaches 1 bar. The benefit of this solution is that no exterior is required.
図5は、第4の実施例のカートリッジ(22)を示す。焙煎されて挽かれたコーヒー(24)が、剛性シート(23)と、濾紙層(25)およびカバー(26)から形成された第2シートとの間に包装されている。シート(25)および(26)は、(27)のところでシート(23)に接合されている。抽出するには、カバー(26)を取り外し、前記カートリッジを欧州特許242556に記載のデバイス内に設置する。この場合にも、必ずしも外装を設ける必要はない。 FIG. 5 shows a cartridge (22) of the fourth embodiment. Roasted and ground coffee (24) is packaged between a rigid sheet (23) and a second sheet formed from a filter paper layer (25) and a cover (26). Sheets (25) and (26) are joined to sheet (23) at (27). For extraction, the cover (26) is removed and the cartridge is placed in the device described in European Patent 242556. Also in this case, it is not always necessary to provide an exterior.
