本発明は、抽出飲料調製用濾過器に関し、具体的には、透明度が高く、かつ雑味が生じにくい抽出飲料を迅速に調製可能で、経済性に優れ、手入れも容易な抽出飲料調製用濾過器に関する。 TECHNICAL FIELD The present invention relates to a filter for preparing an extracted beverage, and more specifically, a filter for preparing an extracted beverage that can quickly prepare an extracted beverage that has high transparency and is less likely to cause unpleasant taste, is economical, and is easy to maintain. Concerning vessels.

コーヒー、日本茶、中国茶、紅茶などの抽出飲料は、焙煎コーヒー豆、茶葉など被抽出物を湯や水などに一定時間浸漬して、被抽出物の成分を湯や水に抽出した後、茶漉し器など濾過器（金網）を用いて濾過されて調製される。 Extracted beverages such as coffee, Japanese tea, Chinese tea, and black tea are prepared by immersing roasted coffee beans, tea leaves, etc. in hot water or water for a certain period of time, and extracting the components of the extract in hot water or water. , is prepared by filtering using a filter (wire mesh) such as a tea strainer.

このような濾過器としては、たとえば、特許文献１では、「急須や湯呑の口縁部に掛止させるフランジ部１ａ又は把手３を設けた合成樹脂製の筒状本体１と、該筒状本体１の解放下端を塞ぐ漉し網２とを備え、漉し網２の周縁部分が、射出成形された筒状本体１の下端部に包埋されていることを特徴とする茶漉し器」が開示されている（実用新案登録請求の範囲）。さらには、この茶漉し器によれば、従来の合成樹脂製の茶漉し器に比べて「筒状本体に漉し網を張設する甚だ面倒な作業が不要になる。」などの効果が奏される旨開示されている（明細書段落［００１７］など） As such a filter, for example, in Patent Document 1, "a synthetic resin cylindrical body 1 provided with a flange portion 1a or a handle 3 to be hooked to the rim of a teapot or tea cup, and the cylindrical body 1 and a strainer 2 closing the open lower end of the tea strainer, wherein the peripheral portion of the strainer 2 is embedded in the lower end of an injection-molded tubular body 1. (Scope of utility model registration claims). Furthermore, according to this tea strainer, compared with conventional tea strainers made of synthetic resin, there are effects such as "no need for the extremely troublesome work of setting a strainer net on the cylindrical main body." (paragraph [0017] of the specification, etc.)

また、抽出飲料の風味などの良否は、茶葉など被抽出物の品質、水や湯の水質などの条件によることが大きいが、被抽出物から成分の抽出過程（抽出飲料の調製過程）の条件にも少なからず影響を受ける。
たとえば、急須内において、茶葉の成分が湯に抽出される際に、茶葉自体は、湯に攪拌されている状態（茶葉が均一に分散されている状態）が望ましい一方で、急須を揺らすなど、静的な状態が動的な状態になると、渋味や雑味が生じてしまう。このように、茶の調製には、複雑な条件を満たす必要があるため、渋味や雑味を低減させた高品質な茶を調製することは、従来の調製技術では容易ではなかった。 In addition, the quality of the flavor of the extracted beverage depends largely on the conditions such as the quality of the extracted material such as tea leaves and the quality of the water or hot water, but the conditions of the process of extracting the components from the extracted material (the preparation process of the extracted beverage) are also affected to a lesser extent.
For example, when the components of the tea leaves are extracted into the hot water in the teapot, it is desirable that the tea leaves themselves are stirred in the hot water (a state in which the tea leaves are evenly dispersed), but the teapot may be shaken. When a static state becomes a dynamic state, astringency and miscellaneous taste occur. As described above, since it is necessary to satisfy complicated conditions for the preparation of tea, it has not been easy to prepare high-quality tea with reduced astringency and unfavorable taste using conventional preparation techniques.

たとえば、茶漉しを備える一般的な急須では、上記のような条件を満たすことは困難であるため、上述のような渋みや雑味が生じやすい傾向にある。 For example, since it is difficult to satisfy the above conditions in a common teapot equipped with a tea strainer, it tends to have an astringent or off-taste as described above.

登録実用新案公報第３００９９８３号公報Registered Utility Model Publication No. 3009983

上述のように、茶漉しなど濾過器の構造が抽出過程の条件に影響を与えるという点を考慮すると、濾過器の改善を通じて、抽出飲料の風味などの向上を図る余地があるといえる。
そこで、本発明者らは、抽出飲料の調製に使用される濾過器の構造を鋭意検討した結果、筒状本体部の内部に特定形状を有する内蓋部が遊嵌されている等の構造を採用することで、下記３つの効果が発揮されることを見出した。 Considering that the structure of a filter such as a tea strainer affects the extraction process conditions as described above, it can be said that there is room for improving the flavor of the extracted beverage by improving the filter.
Therefore, the inventors of the present invention have made intensive studies on the structure of a filter used for preparing an extracted beverage, and have found a structure in which an inner lid having a specific shape is loosely fitted inside a cylindrical main body. It has been found that the following three effects are exhibited by adopting it.

（１）被抽出物から成分の抽出過程（抽出飲料の調製過程）において透明度が高く抽出飲料を調製でき、当該抽出飲料に雑味が生じにくくすることができること。
（２）濾過器中に被抽出物の滞留（濾過部分の目詰まりが発生すること）を、柱状体(a3)を摘まみ上げることで、抽出飲料の濾過器の通過速度の低下を防ぐことができるため、迅速に抽出飲料を調製できること。
（３）濾紙などの消耗品や金網など手入れが煩雑な部材を使用しなくとも、被抽出物が濾過器外に流出せず、ろ過機能を発揮できるとともに、消耗品や手入れが煩雑な部材を使用する必要がないため、経済性に優れ、手入れが容易であること。 (1) It is possible to prepare an extracted beverage with high transparency in the process of extracting components from the material to be extracted (process of preparing an extracted beverage), and to prevent the extracted beverage from having an unpleasant taste.
(2) By picking up the pillars (a3), it is possible to prevent the extraction beverage from slowing down through the filter in order to prevent the substance to be extracted from remaining in the filter (clogging of the filtration part). to be able to quickly prepare an extracted beverage.
(3) Even if consumables such as filter paper and members that require complicated maintenance such as wire mesh are not used, the substance to be extracted does not flow out of the filter, and the filtration function can be exhibited. Since it does not need to be used, it should be economical and easy to maintain.

すなわち、本発明は、透明度が高く、雑味が生じにくい抽出飲料を迅速に調製可能で、経済性に優れ、手入れも容易な抽出飲料調製用濾過器を提供することを目的とする。 It is therefore an object of the present invention to provide a filter for preparing an extracted beverage, which can quickly prepare an extracted beverage having high transparency and less unpleasant taste, is excellent in economic efficiency, and is easy to maintain.

また、「被抽出物」とは、水や湯により成分を抽出される対象であり、たとえば、焙煎されたコーヒー豆や、日本茶、中国茶、紅茶などの各種茶葉などが挙げられる。 In addition, the "extracted material" is an object from which components are extracted with water or hot water, and examples thereof include roasted coffee beans and various tea leaves such as Japanese tea, Chinese tea, and black tea.

本発明に係る抽出飲料調製用濾過器は、図１の付番ＡおよびＢ示されるように、筒状本体部（Ａ）および内蓋部（Ｂ）を必須構成要件として備え、たとえば、図１の付番Ｄに示されるように、筒状本体部（Ａ）の上部（供給口（ａ１））を覆うための蓋部（Ｄ）など、目的に応じて適宜任意部材を有していてもよい。 A filter for preparing an extracted beverage according to the present invention comprises a cylindrical body (A) and an inner lid (B) as essential components, as indicated by numbers A and B in FIG. As shown in the number D of , it may have an arbitrary member as appropriate according to the purpose, such as a lid (D) for covering the upper part (supply port (a1)) of the cylindrical main body (A) good.

各部材の材質は特に限定されるものではなく、プラスチック、ガラス、陶器などが挙げられる。この中でも、被抽出物の滞留による吐出部の閉塞（詰まり）を有効に防止し、抽出飲料を迅速かつ安定的に調製が可能になるという観点からは、各部材の材質は、陶器（例：密度 2.１～2.９[g/cm³]）であることが望ましい。 The material of each member is not particularly limited, and examples thereof include plastic, glass, ceramics, and the like. Among these, the material of each member is ceramic (e.g. It is desirable that the density is 2.1 to 2.9 [g/cm ³ ]).

また、各部材の材質を、陶器とする場合、製造過程において釉薬を使用しない、半磁土からなることが望ましい。また、各部材の製造にあたり、予め部材の形状を象った後、筒状本体部（Ａ）となる部分と内蓋部（Ｂ）となる部分とを、結合させた状態で、焼結工程（合わせ焼き）に供することが望ましい。 Also, when the material of each member is ceramic, it is desirable that the member is made of semi-magnetic clay that does not use glaze in the manufacturing process. In addition, in manufacturing each member, after shaping the shape of the member in advance, the portion to be the cylindrical main body portion (A) and the portion to be the inner lid portion (B) are joined in a sintering step. It is desirable to serve for (cooking).

なお、蓋部（Ｄ）には、後述する柱状体（ｂ３）の上部を収容するための溝部（ｄ１）を有していてもよい。 Note that the lid (D) may have a groove (d1) for accommodating the upper portion of the columnar body (b3) described later.

図３（Ａ）は、筒状本体部（Ａ）の断面図である。当該図に示されるように、筒状本体部（Ａ）は、供給口（ａ１）および吐出口（ａ２）を有する。供給口（ａ１）は、被抽出物と、湯又は水（抽出溶媒）を供給するための口である。また、吐出口（ａ２）は、抽出飲料を下方向（鉛直方向）に吐出するための口である。 FIG. 3(A) is a cross-sectional view of the tubular main body (A). As shown in the figure, the tubular main body (A) has a supply port (a1) and a discharge port (a2). The supply port (a1) is a port for supplying the material to be extracted and hot water or water (extraction solvent). Also, the ejection port (a2) is an opening for ejecting the extracted beverage downward (vertical direction).

図２（Ａ）に示されるように、内蓋部（Ｂ）は、円形扁平板部（ｂ１）と遊嵌凸部（ｂ２）と柱状体（ｂ３）とを有する。 As shown in FIG. 2(A), the inner lid portion (B) has a circular flat plate portion (b1), a loose fitting projection portion (b2), and a columnar body (b3).

ここで、図２（Ａ）に示されるように、遊嵌凸部（ｂ２）は、当該扁平板部（ｂ１）の扁平面（下側扁平面）に設けられる一方、柱状体（ｂ３）は、当該遊嵌凸部（ｂ２）が設けられた扁平面の反対側の扁平面（上側扁平面）の周縁部に設けられている。 Here, as shown in FIG. 2(A), the loose fitting convex portion (b2) is provided on the flat surface (lower flat surface) of the flat plate portion (b1), while the columnar body (b3) is It is provided on the peripheral edge of the flat surface (upper flat surface) on the opposite side of the flat surface on which the loose fitting protrusion (b2) is provided.

図２（Ｂ）は、本発明に係る抽出飲料調製用濾過器および抽出飲料調製器の断面図を示す。当該図に示されるように、内蓋部（Ｂ）の遊嵌凸部（ｂ２）は、筒状本体部（Ａ）の吐出口（ａ２）に遊嵌されている。ここで、「遊嵌」とは、遊嵌凸部（ｂ２）と吐出口（ａ２）とが隙間を生じている状態で挿入（篏合、連結）され、遊嵌凸部（ｂ２）と吐出口（ａ２）とが遊び（隙間）を有しながら嵌め合う状態にある。すなわち、遊嵌凸部（ｂ２）が左右方向（筒状本体部（Ａ）の側面方向）には動きが制限されるものの、上下方向（筒状本体部（Ａ）の供給口（ａ１）方向および吐出口（ａ２）方向）には動きが制限されていない状態において、内蓋部（Ｂ）が筒状本体部（Ａ）の内部に保持されている。 FIG. 2B shows a cross-sectional view of an extracted beverage preparation filter and an extracted beverage preparation device according to the present invention. As shown in the figure, the loose fitting protrusion (b2) of the inner lid (B) is loosely fitted into the discharge port (a2) of the tubular main body (A). Here, "loosely fitting" means that the loosely fitting convex portion (b2) and the discharge port (a2) are inserted (fitted and connected) in a state in which a gap is generated, and the loosely fitting convex portion (b2) and the discharge port (a2) The outlet (a2) is in a fitted state with play (gap). That is, although the movement of the loose fitting projection (b2) is restricted in the left-right direction (side direction of the tubular main body (A)), it is restricted in the vertical direction (in the direction of the supply port (a1) of the tubular main body (A)). and the discharge port (a2 direction)), the inner lid portion (B) is held inside the cylindrical body portion (A).

また、図２（Ｂ）に示されるように、上記遊嵌による連結により、内蓋部（Ｂ）が筒状本体部（Ａ）の内部に保持（収容）され、吐出口（ａ２）が、円形扁平板部（ｂ１）に覆われている。 Further, as shown in FIG. 2(B), the inner cover portion (B) is held (accommodated) inside the cylindrical main body portion (A) by the loose fitting connection, and the discharge port (a2) is It is covered with a circular flat plate portion (b1).

柱状体（ｂ３）は、当該遊嵌凸部（ｂ２）が設けられた扁平面の反対側の扁平面（上側扁平面）における周縁部に設けられているため、内蓋部（Ｂ）の壁面に接触しているか、近傍にある。なお、「周縁部」とは、上側扁平面（円形形状）の中心から離れた部分をいう。 Since the columnar body (b3) is provided on the peripheral edge of the flat surface (upper flat surface) on the opposite side of the flat surface on which the loose fitting protrusion (b2) is provided, the wall surface of the inner lid portion (B) in contact with or in the vicinity of In addition, the "periphery" refers to a portion away from the center of the upper flat surface (circular shape).

図１および図２（Ａ）に示されるように、本発明に係る抽出飲料調製器は、上述の抽出飲料調製用濾過器と、容器部（Ｃ）とを備え、当該抽出飲料調製用濾過器が、容器部（Ｃ）の内部に掛止されていることを特徴とする。 As shown in FIGS. 1 and 2(A), an extracted beverage preparation apparatus according to the present invention includes the extracted beverage preparation filter described above and a container portion (C). is hooked inside the container part (C).

ここで、「掛止」とは、容器部（Ｃ）の内部に、抽出飲料調製用濾過器が、フランジ部などで引っ掛かりながら保持されていることをいう。なお、図２（Ｂ）では、付番ａ３で示されるように、抽出飲料調製用濾過器の供給口（ａ１）の周囲に設けられたフランジ部（ａ３）が、掛止手段として機能しているが、掛止手段としては特に限定されるものではない。 Here, the term "hooking" means that the filter for preparing an extracted beverage is held inside the container portion (C) while being caught by the flange portion or the like. In FIG. 2(B), as indicated by number a3, the flange portion (a3) provided around the supply port (a1) of the filter for preparing extracted beverage functions as a hooking means. However, the latching means is not particularly limited.

次いで、図３を適宜参照しながら、発明に係る抽出飲料調製器を用いた、抽出飲料の調製手順について説明する。なお、図３は、容器部（Ｃ）の図示を省略している。 Next, a procedure for preparing an extracted beverage using the extracted beverage preparation device according to the invention will be described with appropriate reference to FIG. In addition, FIG. 3 omits illustration of the container portion (C).

図３（Ａ）および（Ｂ）に示されるように、まず、内蓋部（Ｂ）を筒状本体部（Ａ）の内部に収容する。ここで、上述したように、内蓋部（Ｂ）の遊嵌凸部（ｂ２）は、筒状本体部（Ａ）の吐出口（ａ２）に遊嵌されることになる。 As shown in FIGS. 3A and 3B, first, the inner lid portion (B) is accommodated inside the cylindrical body portion (A). Here, as described above, the loose fitting projection (b2) of the inner lid (B) is loosely fitted into the discharge port (a2) of the tubular main body (A).

次に、図３（Ｃ）に示されるように、供給口（ａ１）から被抽出物（日本茶、中国茶、紅茶など）と、湯又は水（抽出溶媒）を供給して、被抽出物Ｅの抽出成分を湯又は水Ｆに溶出させる抽出工程を実施する。ここで、詳細なメカニズムは不明であるが、筒状部（Ａ）の供給口（ａ１）から被抽出物と水又は湯が供されると、被抽出物由来の抽出成分を含む水又は湯（抽出飲料）は、鉛直方向への水圧を生じる。 Next, as shown in FIG. 3(C), the material to be extracted (Japanese tea, Chinese tea, black tea, etc.) and hot water or water (extraction solvent) are supplied from the supply port (a1) to obtain the material to be extracted. An extraction step of eluting the extracted components of E into hot water or water F is carried out. Here, although the detailed mechanism is unknown, when the material to be extracted and water or hot water are supplied from the supply port (a1) of the cylindrical part (A), the water or hot water containing the extraction component derived from the material to be extracted (brewed beverage) creates vertical water pressure.

そして、抽出飲料Ｇは、遊嵌凸部（ｂ２）と吐出口（ａ２）との遊嵌部分（隙間）に流入し、抽出飲料が鉛直方向（下方向、容器部方向）に流出する。一方で、茶葉が当該遊嵌部分に集積して目詰まりが発生する（茶葉により遊嵌部分が塞がれる）ことで、次第に、容器部への流出が抑制されることになる。
この場合、柱状体（ｂ３）を、「つまみ」として上部へ若干移動することで、再度、遊嵌部分に隙間が生じ、容器部への流出を回復することができる。 Then, the extracted beverage G flows into the loosely fitted portion (gap) between the loosely fitted convex portion (b2) and the discharge port (a2), and the extracted beverage flows out in the vertical direction (downward, toward the container portion). On the other hand, tea leaves accumulate in the loose fitting portion and clogging occurs (the loose fitting portion is blocked by tea leaves), thereby gradually suppressing the outflow to the container portion.
In this case, by slightly moving the columnar body (b3) upward as a "knob", a gap is generated again in the loose fitting portion, and the outflow to the container portion can be restored.

この一連の操作においては、被抽出物（茶葉等）の攪拌状態（均一に拡散された状態）から被抽出物（茶葉等）は、徐々に鉛直方向（下方向）に沈降して、図３の付番Ｅに示されるように、内蓋部（図３付番Ｂ）上に堆積することになる。ここで、容器部の底部堆積した非抽出物は、フィルターとしての機能を発揮し、抽出飲料の透明度を高くでき、かつ、抽出飲料に雑味が生じにくくすることができる。 In this series of operations, the object to be extracted (tea leaves, etc.) is gradually sedimented in the vertical direction (downward) from the stirring state (uniformly dispersed state) of the object to be extracted (tea leaves, etc.). will deposit on the inner lid (FIG. 3, B), as indicated by the E number in FIG. Here, the non-extracted matter deposited on the bottom of the container part functions as a filter, and can increase the transparency of the extracted beverage and prevent the extracted beverage from having an unpleasant taste.

更には、本発明に係る抽出飲料調製器は、上述のような内蓋部（Ｂ）の働きによって、濾紙などの消耗品や、抽出飲料（特に、日本茶）の風味を劣化させる金網などを用いなくても、十分に濾過機能を発揮することができる。そして、濾紙などの消耗品や金網など手入れが煩雑な部材を使用しなくてもよいので、経済性に優れ、手入れが容易であるといえる。 Furthermore, the extracted beverage preparation device according to the present invention uses the function of the inner lid portion (B) as described above to remove consumables such as filter paper and wire mesh that deteriorates the flavor of the extracted beverage (especially Japanese tea). Even if it is not used, the filtering function can be fully exhibited. In addition, since consumables such as filter paper and members requiring complicated maintenance such as wire mesh need not be used, it can be said to be economical and easy to maintain.

本発明に係る抽出飲料調製用濾過器によれば、抽出飲料調製器に使用することで、透明度が高く、かつ雑味が生じにくい抽出飲料を迅速に調製が可能で、経済性に優れる抽出飲料調製用濾過器を提供することができる。 INDUSTRIAL APPLICABILITY According to the filter for preparing an extracted beverage according to the present invention, it is possible to quickly prepare an extracted beverage with high transparency and less unpleasant taste by using it in an extracted beverage preparation device, and the extracted beverage is excellent in economic efficiency.
