The adapter 3 includes a ring-shaped mounting portion 3a, and a protruding portion 3b is further formed on the mounting surface. By forming the protrusion 3b, the extraction filter can be easily suppressed.
　アダプタ３の裏面側には、リング状の位置決め凹部３ｃが形成されている。この位置決め凹部３ｃが突出壁２３ａに挿入されることで、アダプタ３を確実に位置決めすることができる。また、リング状載置部３ａの中央部には円形の挿入孔が形成され、後述の抽出フィルターのフィルター部を挿入することができる。 A ring-shaped positioning recess 3 c is formed on the back side of the adapter 3. The adapter 3 can be reliably positioned by inserting the positioning recess 3c into the protruding wall 23a. In addition, a circular insertion hole is formed in the center of the ring-shaped mounting portion 3a, and a filter portion of an extraction filter described later can be inserted.
　図５は、エスプレッソコーヒー抽出用フィルターを装着するためのアダプタ３０を示す図であり、（ａ）は平面図（ｂ）は断面図を示す。アダプタ３０も、リング状の載置部３０ａを備えており、その載置面の上にはさらに突出部３０ｂが形成されている。ドリップコーヒー用アダプタ３とは異なり、中央部に挿入孔は形成されず、代わりに小さな小孔が多数形成されたフィルター３１が取り付けられている。 FIG. 5 is a view showing an adapter 30 for mounting an espresso coffee extraction filter, and FIG. 5A is a plan view and FIG. 5B is a cross-sectional view. The adapter 30 also includes a ring-shaped mounting portion 30a, and a protruding portion 30b is further formed on the mounting surface. Unlike the drip coffee adapter 3, no insertion hole is formed at the center, and instead a filter 31 having a large number of small holes is attached.
　アダプタ３は、好ましくは、ステンレス等の金属をプレス成型することで制作することができる。あるいは、樹脂成型により製作してもよい。 The adapter 3 can be preferably produced by press molding a metal such as stainless steel. Or you may manufacture by resin molding.
　＜抽出フィルターの構成＞
　次に、アダプタ３とともに使用される抽出フィルターの構成を説明する。この抽出フィルターは、本来はドリップコーヒー用であり、ドリップマシンに装着することができる。また、この抽出フィルターを図１のエスプレッソマシンでも使用できるように、構造上の工夫がある。 <Extraction filter configuration>
Next, the configuration of the extraction filter used with the adapter 3 will be described. This extraction filter is originally for drip coffee and can be attached to a drip machine. Further, there is a structural device so that this extraction filter can be used in the espresso machine of FIG.
　図６は、抽出フィルターの断面形状を示す図である。図７は、抽出フィルターを構成する要素を示す分解斜視図である。抽出フィルター４は、コーヒー粉末（嗜好品に相当）が収容されるフィルター部４０と、このフィルター部４０の上部に取り付けられる平板状の蓋部４１とから構成される。 FIG. 6 is a diagram showing a cross-sectional shape of the extraction filter. FIG. 7 is an exploded perspective view showing elements constituting the extraction filter. The extraction filter 4 includes a filter part 40 in which coffee powder (corresponding to a favorite product) is accommodated, and a flat lid part 41 attached to the upper part of the filter part 40.
　蓋部４１は、フィルター部４０側に位置し、透水性を有していない第１シート部材４２と、この第１シート部材４２の上に積層され、透水性を有する第２シート部材４３と、の二層構造により構成される。フィルター部４０は、不織布により形成され、好ましくは、スパンボンド不織布により形成される。フィルター部４０の上部には空間部Ｓが形成される。この空間部Ｓにより、湯で膨張したコーヒー粉末と湯が滞留接触し、十分な抽出を行うことができる。 The lid portion 41 is located on the filter portion 40 side, and has a first sheet member 42 that does not have water permeability, a second sheet member 43 that is laminated on the first sheet member 42 and has water permeability, It is constituted by the two-layer structure. The filter part 40 is formed of a nonwoven fabric, and preferably is formed of a spunbond nonwoven fabric. A space S is formed in the upper part of the filter unit 40. By this space S, the coffee powder swollen with hot water stays in contact with hot water, and sufficient extraction can be performed.
　第１シート部材４２は、一層もしくは多層の樹脂フィルムにより形成される。第２シート部材４３は、スパンボンド不織布等の不織布により形成される。フィルター部４０には、フランジ４０ａが形成され、このフランジ４０ａにて蓋部４１と接着される。また、第１シート部材４２と第２シート部材４３も、周縁部Ａ（図５の斜線部参照）のみで接着されており、中央部Ｂは接着されていない。従って、中央部Ｂにおいて、第１シート部材４２と第２シート部材４３の間は接着されていないので、それらの間に空間部（あるいは隙間）を形成させることができる。 The first sheet member 42 is formed of a single layer or multilayer resin film. The second sheet member 43 is formed of a nonwoven fabric such as a spunbond nonwoven fabric. The filter portion 40 is formed with a flange 40a, and is bonded to the lid portion 41 with the flange 40a. Moreover, the 1st sheet member 42 and the 2nd sheet member 43 are also adhere | attached only by the peripheral part A (refer the shaded part of FIG. 5), and the center part B is not adhere | attached. Accordingly, since the first sheet member 42 and the second sheet member 43 are not bonded at the central portion B, a space (or a gap) can be formed between them.
　第１シート部材４２の中央には舌片状の孔部４２ａが形成される。かかる孔部４２ａは、製造工程において、第１シート部材４２にカットラインＣＬを入れることで形成することができる。カットラインＣＬを入れるのではなく、打ち抜きにより孔部４２ａを形成してもよいが、その場合、小さな廃棄片が発生し、異物混入のトラブルを引き起こす原因となる。そこで、上記カットラインＣＬを形成することで、廃棄片の発生を防止し、上記トラブルの発生を未然に防止することができる。孔部４２ａの大きさは、直径３ｍｍ相当である。 A tongue-like hole 42 a is formed at the center of the first sheet member 42. The hole 42a can be formed by inserting a cut line CL in the first sheet member 42 in the manufacturing process. The hole 42a may be formed by punching instead of entering the cut line CL. However, in that case, a small waste piece is generated, which causes a problem of foreign matter contamination. Therefore, by forming the cut line CL, it is possible to prevent generation of waste pieces and to prevent occurrence of the trouble. The size of the hole 42a is equivalent to 3 mm in diameter.
　また、第１シート状部材４２と第２シート状部材４３には、それぞれ手で持ちやすくするためのつまみ部４２ｃ，４３ａが一体形成される。 Also, the first sheet-like member 42 and the second sheet-like member 43 are integrally formed with knob portions 42c and 43a for easy holding by hand.
　カットラインＣＬについては、本実施形態ではＣ字状（所定形状に相当）としているが、Ｖ字状等の適宜の形状を採用することができる。 The cut line CL is C-shaped (corresponding to a predetermined shape) in this embodiment, but an appropriate shape such as a V-shape can be adopted.
　第１シート部材４２の素材については、例えば、ＣＰＰ（無延伸ポリプロピレン）フィルム（厚さ５０μｍ）の一層構造、ＰＥ（ポリエチレン）／ＰＰ（ポリプロピレン）／ＰＥフィルムの三層構造（トータル厚さ５０μｍ）、ＰＰ／ＰＰ／ＰＰフィルムの三層構造（トータル厚さ５０μｍ）等により形成することができる。抽出液の品質、接着性、強度等を考慮して適切な素材を選択することができる。 As for the material of the first sheet member 42, for example, a single layer structure of a CPP (unstretched polypropylene) film (thickness 50 μm), a three layer structure of PE (polyethylene) / PP (polypropylene) / PE film (total thickness 50 μm) , PP / PP / PP film three-layer structure (total thickness 50 μm), etc. An appropriate material can be selected in consideration of the quality, adhesiveness, strength, etc. of the extract.
　フィルター部４０を構成する素材としては、例えば、旭化成せんい株式会社製のスパンボンドＹ２５２００を用いることができる。第２シート部材４３を構成する素材としては、例えば、大紀商事株式会社製のオキロンＣＥＷ－３０を使用することができる。 As a material constituting the filter unit 40, for example, Spunbond Y25200 manufactured by Asahi Kasei Fibers Corporation can be used. As a material constituting the second sheet member 43, for example, Okiron CEW-30 manufactured by Daiki Shoji Co., Ltd. can be used.
　＜ドリップコーヒー抽出時の動作＞
　次に、図６に示す抽出フィルターでコーヒーを抽出するときの動作を説明する。図８は、ドリップマシンで抽出する場合の動作を示す。注湯は注湯針５を介して行われる。図８（ａ）は、抽出開始前の状態を示す。抽出時は、注湯針５が下降し、蓋部４１を貫通する。蓋部４１のうち、第２シート部材４３については、穿孔しつつ下降し、第１シート部材４２については、舌片状の孔部４２ａを下方に折り曲げながら下降する。所定位置まで加工した後、注湯針５の先端から注湯する。これにより、コーヒーカップＣにコーヒーを抽出させることができる。 <Operation when extracting drip coffee>
Next, the operation when extracting coffee with the extraction filter shown in FIG. 6 will be described. FIG. 8 shows the operation when extracting with a drip machine. The pouring is performed through the pouring needle 5. FIG. 8A shows a state before the start of extraction. At the time of extraction, the pouring needle 5 descends and penetrates the lid portion 41. Of the lid portion 41, the second sheet member 43 descends while being perforated, and the first sheet member 42 descends while bending the tongue-shaped hole portion 42a downward. After processing to a predetermined position, the hot water is poured from the tip of the pouring needle 5. Thereby, coffee can be extracted to the coffee cup C.
　次に、図９により、エスプレッソマシンでドリップコーヒーを抽出する場合の動作を説明する。まず、図２に示すフィルター装着具２の操作部２２を操作して、載置部２３を露出させる（図３）。次に、突出壁２３ａにアダプタ３の位置決め凹部３ｃを挿入して、抽出フィルターをセットする。抽出フィルターを載置したのち、操作部２２を元の位置に戻すと、押え部２４により、抽出フィルターの蓋部４１の周辺部を押圧することができる。図９（ａ）は、抽出フィルターをセットした時の断面図（セット完了時）を示している。 Next, the operation when extracting drip coffee with an espresso machine will be described with reference to FIG. First, the operation part 22 of the filter mounting tool 2 shown in FIG. 2 is operated to expose the placement part 23 (FIG. 3). Next, the positioning recess 3c of the adapter 3 is inserted into the protruding wall 23a, and the extraction filter is set. After the extraction filter is placed, when the operation unit 22 is returned to the original position, the pressing portion 24 can press the peripheral portion of the lid portion 41 of the extraction filter. FIG. 9A shows a cross-sectional view when the extraction filter is set (when the setting is completed).
　次に、エスプレッソマシンに設けられた注湯ボタン等の操作で、図９（ａ）に示すように、蓋部４１の全面にわたって注湯される（矢印Ｄ参照）。蓋部４１の周辺部から供給されるお湯は、（ｂ）に示すように、できるだけ中央の孔部４２ａの方に向かうように作用する。蓋部４１の上面側の第２シート部材４３は、不織布で形成されているので、お湯が染み込みやすく、蓋部４１の上部に溜まることはない。 Next, as shown in FIG. 9A, hot water is poured over the entire surface of the lid portion 41 by an operation of a hot water button provided on the espresso machine (see arrow D). The hot water supplied from the peripheral part of the lid part 41 acts as far as possible toward the central hole part 42a as shown in FIG. Since the second sheet member 43 on the upper surface side of the lid portion 41 is formed of a nonwoven fabric, hot water is likely to permeate and does not accumulate on the upper portion of the lid portion 41.
　また、第１シート部材４２と第２シート部材４３は、周縁部のみで接着されているので、お湯の圧力により空間部Ｅ（隙間）が形成されやすい。この空間部Ｅに導入されるお湯の呼び水効果により、蓋部４１の上面の湯だまりを軽減させることができる。 Further, since the first sheet member 42 and the second sheet member 43 are bonded only at the peripheral edge portion, the space portion E (gap) is easily formed by the pressure of hot water. Due to the priming effect of the hot water introduced into the space E, the hot water pool on the upper surface of the lid 41 can be reduced.
　仮に、蓋部４１を第２シート部材４３のみの一層構造にすると、全面からお湯が注湯されてしまい、味の薄いコーヒーとなり風味が損なわれる。しかし、本発明の場合、中央の孔部４２ａから注湯されるので、加水が均一になり、再現性の高いコーヒー抽出が可能になる。また、エスプレッソマシンを使用した場合でも品質が安定し、かつ風味のあるドリップコーヒーを抽出させることができる。 Temporarily, if the cover part 41 is made into the single layer structure of only the 2nd sheet | seat member 43, hot water will be poured from the whole surface and it will become a coffee with a light taste and a flavor will be impaired. However, in the case of the present invention, since the hot water is poured from the central hole 42a, the water becomes uniform and the coffee extraction with high reproducibility becomes possible. Further, even when an espresso machine is used, it is possible to extract a drip coffee having a stable quality and a flavor.
　＜エスプレッソコーヒー抽出＞
　次に、エスプレッソコーヒーの抽出を行う場合について説明する。図１０は、図１に示すエスプレッソマシンに使用されるエスプレッソコーヒー抽出フィルターを示す図であり、（ａ）は外観斜視図（ｂ）は断面図を示す図である。エスプレッソコーヒー抽出フィルターは、上下対称的に下部フィルター部５０と上部フィルター部５１により構成される。ドリップコーヒー抽出フィルターに比べて、下部フィルター部５０の高さが低くなっている。また、フィルター部５０，５１は、通常の一重構造である。 <Espresso coffee extraction>
Next, the case where espresso coffee is extracted will be described. FIG. 10 is a view showing an espresso coffee extraction filter used in the espresso machine shown in FIG. 1, and (a) is an external perspective view (b) is a cross-sectional view. The espresso coffee extraction filter is configured by a lower filter unit 50 and an upper filter unit 51 symmetrically in the vertical direction. Compared with the drip coffee extraction filter, the height of the lower filter part 50 is low. The filter units 50 and 51 have a normal single structure.
　エスプレッソコーヒー抽出フィルターをセットするときは、図５に示すアダプタ３０が使用される。セットするまでの動作は、ドリップコーヒーを抽出する場合と同じである。図１１は、実際に抽出するときの様子を示す図である。 When the espresso coffee extraction filter is set, the adapter 30 shown in FIG. 5 is used. The operation until setting is the same as when drip coffee is extracted. FIG. 11 is a diagram showing a state when actual extraction is performed.
　＜別実施形態＞
　図１２は、アダプタ３の別実施形態を示す図である。載置部３ａに突出部を設ける代わりに、ゴムシート３ｄ（摩擦係数の高い素材に相当）を設けた例である。これにより、抽出フィルターの蓋部４１が滑らないように確実に保持させることができる。 <Another embodiment>
FIG. 12 is a diagram showing another embodiment of the adapter 3. This is an example in which a rubber sheet 3d (corresponding to a material having a high friction coefficient) is provided instead of providing the protruding portion on the mounting portion 3a. Thereby, it can hold | maintain reliably so that the cover part 41 of an extraction filter may not slip.
　本実施形態に係るアダプタ３に取っ手を設けて操作しやすいようにしてもよい。 A handle may be provided on the adapter 3 according to this embodiment so that it can be operated easily.
　本実施形態では、ドリップコーヒー用の抽出フィルターをエスプレッソマシンで使用する場合の例を説明したが、本発明は、これに限定されるものではない。例えば、紅茶やお茶の抽出フィルターをエスプレッソマシン、あるいは、そのほかの抽出用マシンに使用してもよい。 In this embodiment, an example in which an extraction filter for drip coffee is used in an espresso machine has been described, but the present invention is not limited to this. For example, a tea or tea extraction filter may be used in an espresso machine or other extraction machine.
