Description

本発明は、通水濾過性シート製の袋本体に充填された抽出材料を湯に浸漬して抽出液を得る抽出バッグに関する。 TECHNICAL FIELD The present invention relates to an extraction bag for obtaining an extract by immersing an extraction material filled in a bag body made of a water-permeable filterable sheet in hot water.

従来、緑茶、紅茶、ウーロン茶などの飲料を手軽にいれるために、吊し糸付きの通水性の袋本体にこれらの茶葉が充填されたティーバッグが広く用いられている。コーヒーについても、コーヒー粉に注湯するドリップタイプの抽出バッグの他に、コーヒー粉が充填された袋本体を湯に浸漬させるティーバッグタイプのコーヒー抽出バッグが使用されている。しかしながら、ティーバッグタイプのコーヒー抽出バッグを湯に浸漬しようとしても、コーヒー粉に二酸化炭素が含まれるためにコーヒー粉を充填した袋本体が湯中で浮き上がり易く、コーヒーを十分に抽出することが難しい。そこで、薄板状部材で形成されたフック片を、コーヒー粉を充填する袋本体の片面に取り付けておき、コーヒー粉が充填された袋本体が湯中で浮き上がらないように、フック片をカップの縁に掛止できるようにしたものが提案されている（特許文献１）。 2. Description of the Related Art Conventionally, in order to conveniently brew beverages such as green tea, black tea, and oolong tea, tea bags in which a water-permeable bag body with a hanging string and filled with these tea leaves have been widely used. As for coffee, in addition to a drip-type coffee extraction bag in which hot water is poured into coffee powder, a tea bag-type coffee extraction bag in which a bag body filled with coffee powder is immersed in hot water is used. However, even if a tea bag type coffee extraction bag is immersed in hot water, the coffee powder contains carbon dioxide, so the main body of the bag filled with the coffee powder tends to float in the hot water, making it difficult to extract the coffee sufficiently. . Therefore, a hook piece formed of a thin plate-like member is attached to one side of the bag body to be filled with coffee grounds, and the hook piece is attached to the rim of the cup so that the bag body filled with coffee grounds does not float in hot water. There has been proposed a device that can be hooked to the body (Patent Document 1).

また、薄板状部材を折り曲げてパンタグラフのように伸縮する構造とした把持部を、コーヒー粉が充填された袋本体に取り付け、袋本体が浸漬している湯中で該把持部を上下させることによりコーヒーの抽出を促進させることが提案されている（特許文献２）。 In addition, by attaching a grip portion having a structure in which a thin plate-like member is bent and stretched like a pantograph to a bag body filled with coffee grounds, the grip portion is moved up and down in hot water in which the bag body is immersed. Promoting coffee extraction has been proposed (Patent Document 2).

しかしながら、コーヒー粉が充填された袋本体を湯に浸漬させる従来のコーヒー抽出バッグでは、薄板状部材で形成されたフック片又は把持部を把持し、浮き上がろうとする袋本体を強制的に湯中に沈めようとしても薄板状部材が折れ曲がったり撓んだりして袋本体を湯中に沈めることは困難である。コーヒーの抽出を促進させるために、フック片又は把持部を上下させても、袋本体は湯中で把持部と同様には上下しない。また、一時的に袋本体が湯中に沈んでも、袋本体に充填されたコーヒー粉全体の表層だけが湯で膨潤し、コーヒー粉全体の内部には湯が浸透しにくい。そのため、袋本体を湯に浸漬させるティーバッグタイプの抽出バッグでは、ドリップタイプと同程度の濃さのコーヒー液をドリップタイプと同程度以下の時間で得ることが難しくなっている。 However, in a conventional coffee brewing bag in which a bag body filled with coffee grounds is immersed in hot water, a hook piece or grip formed of a thin plate-like member is gripped to forcibly lift the bag body with hot water. It is difficult to submerge the bag main body in hot water because the thin plate-like member is bent or bent even if it is attempted to be submerged in the hot water. Even if the hook piece or the gripping part is moved up and down in order to facilitate coffee extraction, the bag body does not move up and down like the gripping part in hot water. Also, even if the bag body is temporarily submerged in hot water, only the surface layer of the whole coffee powder filled in the bag body swells with the hot water, and the hot water hardly penetrates into the inside of the whole coffee powder. For this reason, it is difficult for a teabag-type extraction bag in which the bag body is immersed in hot water to obtain a coffee liquid of the same concentration as that of the drip type in less time than that of the drip type.

これに対し、本発明は、コーヒー粉等の抽出材料が充填されている袋本体を湯に浸漬させることにより抽出液を得るティーバッグタイプの抽出バッグであって、袋本体を湯中に沈めたり、湯中で上下させたりすることが容易であり、また、抽出バッグから手を離しても袋本体が湯中に浸漬した状態を安定に保持することができ、十分な濃さの抽出液を簡便に得られるようにすることを課題とする。 In contrast, the present invention is a tea bag type extraction bag that obtains an extract by immersing a bag body filled with extraction material such as coffee grounds in hot water, wherein the bag body is submerged in hot water. , it is easy to move up and down in hot water, and even if you take your hand off the extraction bag, the bag body can be stably maintained in the hot water, and a sufficiently concentrated extract can be obtained. The object is to make it easy to obtain.

本発明者は、抽出材料が充填された袋本体に薄板状部材が取り付けられているティーバッグタイプの抽出バッグにおいて、袋本体の一つの面に袋本体上下方向に伸びた薄板状部材を袋本体の上部で固定し、下部は袋本体から引き起こし可能となるように設け、引き起こし時に把持部が袋本体上下方向の折れ線により把持部の上端から下端まで２つ折りされるようにすると、２つ折りにした把持部の長手方向を袋本体上下方向にまで立てることが容易となることを想到した。また、こうして２つ折りにした把持部は袋本体上部から伸びたリジッドな棒状となり、棒状となった把持部を把持することで袋本体を湯中に沈めたり上下させたりすることができること、また、この把持部の２つ折りにより袋本体内部にスペースが形成され、袋本体内部に湯が入り易くなり、袋本体内の抽出材料の表面だけでなく内部にも湯が浸透しやすくなり、抽出が促進されること、さらに把持部から手を離しても把持部はカップの内壁に支持されて湯から突出した状態を維持することができ、これにより抽出後に把持部を把持して抽出バッグをカップから取り出すことも容易になることを想到し、本発明を完成させた。 The present inventor has proposed a tea bag type extraction bag in which a thin plate-like member is attached to a bag body filled with an extraction material. The upper part of the bag is fixed, and the lower part is provided so that it can be lifted from the bag body. The inventors have conceived that the longitudinal direction of the gripping portion can be easily erected in the up-down direction of the bag body. In addition, the grip part folded in two in this way becomes a rigid rod-shaped part extending from the upper part of the bag body, and by gripping the rod-shaped grip part, the bag body can be submerged in hot water or moved up and down. A space is formed inside the bag body by folding the grip part in two, making it easier for hot water to enter the inside of the bag body. Furthermore, even if the hand is released from the gripping part, the gripping part is supported by the inner wall of the cup and can be maintained in a state of protruding from the hot water. The present invention was completed with the idea that it would be easy to take out.

即ち、本発明は、通水濾過性シートから形成された袋本体、袋本体の外表面に設けられた薄板状部材、袋本体内に充填された抽出材料を有する抽出バッグであって、
袋本体は対向する２面、及び該２面の縁辺となる上辺を有し、
薄板状部材は前記２面の片面に袋本体上下方向に伸びた把持部を有し、
把持部の上部が前記片面の上部に固定され、把持部の下部が該片面から引き起こし可能であり、
把持部には、該把持部を２つ折り可能とする袋本体上下方向の折れ線が、該把持部の幅方向の中央部で該把持部の上端から下端にかけて形成されている抽出バッグを提供する。 That is, the present invention provides an extraction bag having a bag body formed from a water-permeable and filterable sheet, a thin plate member provided on the outer surface of the bag body, and an extraction material filled in the bag body,
The bag body has two opposing surfaces and an upper side that serves as the edge of the two surfaces,
The thin plate-shaped member has a grip portion extending in the vertical direction of the bag body on one of the two surfaces,
The upper part of the grip is fixed to the upper part of the one side, and the lower part of the grip can be raised from the one side,
To provide an extraction bag in which a fold line in the vertical direction of a bag body that allows the gripping part to be folded in two is formed from the upper end to the lower end of the gripping part at the central part in the width direction of the gripping part.

また本発明は、上述の抽出バッグにおいて袋本体に抽出材料が充填されておらず、袋本体に抽出材料充填用の開口部が設けられている手詰め用抽出バッグを提供する。 The present invention also provides a hand-packed extraction bag in which the bag body is not filled with the extraction material in the extraction bag described above, and the bag body is provided with an opening for filling the extraction material.

本発明によれば、抽出材料が充填された袋本体の一つの面に設けられた薄板状部材からなる把持部の下部を袋本体から引き起こし、そこに形成されている袋本体上下方向の折れ線で折ると把持部はその上端から下端までが容易に２つ折りになり、かつ２つ折りになった把持部を袋本体上下方向にまで容易に引き起こすことができる。この２つ折りにした把持部は袋本体の上部に固定されたリジッドな棒状となり、袋本体は上部のみが２つ折りになって袋本体内にスペースが形成される。したがって、棒状にした把持部を把持することで袋本体をカップ内の湯に沈めたり上下させたりすることが可能となる。また、袋本体内にはスペースが形成されていることにより、袋本体をカップ内の湯に沈めたり湯中で上下させたりすると、袋本体内にも容易に湯が通り、袋本体に充填されている抽出材料の表面だけでなく内部にも湯が浸透する。よって、抽出が促進されて抽出速度が速まり、ドリップタイプの抽出方式と同等以上の濃さの抽出液を短時間で簡便に得ることができる。 According to the present invention, the lower part of the grasping part made of a thin plate-like member provided on one surface of the bag body filled with the extraction material is lifted from the bag body, and the fold line formed there in the vertical direction of the bag body When folded, the grip portion can be easily folded in two from the upper end to the lower end, and the folded grip portion can be easily pulled upward and downward of the bag body. The gripping portion folded in two becomes a rigid bar-like shape fixed to the upper part of the bag body, and only the upper part of the bag body is folded in two to form a space inside the bag body. Therefore, by gripping the rod-shaped gripping portion, the bag body can be submerged in the hot water in the cup and moved up and down. In addition, since a space is formed in the bag body, when the bag body is submerged in the hot water in the cup or moved up and down in the hot water, the hot water flows easily into the bag body and the bag body is filled. The hot water permeates not only the surface of the extraction material used but also the inside. Therefore, the extraction is accelerated, the extraction speed is increased, and an extract having a concentration equal to or higher than that of the drip type extraction method can be easily obtained in a short time.

また、カップ内で把持部から手を離しても把持部がカップ内壁で支持され、把持部が湯から突出した状態を維持させることができる。したがって、袋本体を湯に沈めた状態でその場から一旦離れても抽出を進行させることができ、再度把持部を把持して袋本体を湯中で上下させることもでき、抽出後には袋本体を湯から引き上げることも容易となる。 In addition, even if the hand is released from the gripping portion in the cup, the gripping portion is supported by the inner wall of the cup, and the state in which the gripping portion protrudes from the hot water can be maintained. Therefore, even if the bag body is immersed in hot water, the extraction can proceed even if the operator leaves the place once. can be easily pulled up from hot water.

FIG. 1A is a plan view of an extraction bag 1A according to an embodiment of the present invention, showing a state in which the grasping portion of the thin plate-like member is not raised, and FIG. 1B is a rear view thereof. In FIG. 1A , the area filled with oblique lines represents the bonding area A between the thin plate member 10 and the bag body 3 , and the area filled with dots represents the surface of the bag body 3 . In addition, in this invention, the sticking area|region A is not restricted to the illustrated aspect.

この抽出バッグ１Ａは、通水濾過性シートで形成された袋本体３、袋本体３に設けられた薄板状部材１０、袋本体３内に充填された抽出材料を有する。本発明において、袋本体３は対向する２面３ｘ、３ｙと該２面３ｘ、３ｙの縁辺となる上辺３ａを有しており、本実施例では袋本体３は平袋となっている。薄板状部材１０は、袋本体の対向する２面の片面３ｘに設けられており（図１Ａ）、その反対面３ｙには設けられていない（図１Ｂ）。 This extraction bag 1A has a bag body 3 formed of a water permeable filterable sheet, a thin plate-like member 10 provided on the bag body 3, and an extraction material filled in the bag body 3. As shown in FIG. In the present invention, the bag body 3 has two opposing surfaces 3x and 3y and an upper side 3a which serves as the edge of the two surfaces 3x and 3y. In this embodiment, the bag body 3 is a flat bag. The thin plate member 10 is provided on one side 3x of the two opposing sides of the bag body (FIG. 1A), and is not provided on the opposite side 3y (FIG. 1B).

薄板状部材１０は袋本体３の一つの面３ｘに袋本体上下方向に伸びた短冊形の把持部１１を有する。この薄板状部材１０は、袋本体３の上辺３ａ近傍から底辺３ｂ近傍に至る長さを有している。把持部１１は、袋本体３の上辺３ａに沿った部分が幅広に突出しており、その幅広部分も含めて袋本体の上辺３ａに沿った帯状領域が把持部１１と袋本体３との貼着領域Ａとなり、この貼着領域Ａによって把持部１１が袋本体の面３ｘに固定されている。一方、把持部１１の下部、より具体的には、貼着領域Ａよりも袋本体底辺側の部分は袋本体３と貼着されていない。したがって、図２に示すように、把持部１１は袋本体３から引き起こし可能である。 The thin plate-like member 10 has a strip-shaped grip portion 11 extending in the vertical direction of the bag body 3 on one surface 3x of the bag body 3. As shown in FIG. This thin plate-like member 10 has a length from the vicinity of the top side 3a of the bag body 3 to the vicinity of the bottom side 3b. The gripping portion 11 protrudes broadly along the upper side 3a of the bag body 3, and the gripping portion 11 and the bag body 3 are adhered to each other in a band-like region along the upper side 3a of the bag body, including the widened portion. The gripping portion 11 is fixed to the surface 3x of the bag body by the pasting area A. As shown in FIG. On the other hand, the lower portion of the grip portion 11 , more specifically, the portion closer to the bottom side of the bag body than the sticking area A is not stuck to the bag body 3 . Therefore, as shown in FIG. 2, the gripping portion 11 can be raised from the bag body 3 .

また、把持部１１は、その上辺１１ａが袋本体３の上辺３ａから袋本体の面３ｘの外に突出するように設けられている。 The gripping portion 11 is provided so that its upper side 11a protrudes from the upper side 3a of the bag body 3 to the outside of the surface 3x of the bag body.

なお、本発明において把持部の上辺１１ａは袋本体の上辺３ａと重なっていても良く、図６に示す抽出バッグ１Ｂのように、把持部の上辺１１ａが袋本体の上辺３ａよりも袋本体底辺側に位置してもよい。また、袋本体３の上辺３ａに沿った把持部１１の部分を幅広に形成するにあたり、図７に示す抽出バッグ１Ｃのように、把持部の上辺１１ａが把持部の下辺１１ｂに対してなだらかに幅広になっていてもよい。 In the present invention, the upper side 11a of the grip portion may overlap the upper side 3a of the bag body. Like the extraction bag 1B shown in FIG. can be located on the side. Further, in forming the portion of the gripping portion 11 along the upper side 3a of the bag main body 3 to be wide, the upper side 11a of the gripping portion is smoothed with respect to the lower side 11b of the gripping portion as in the extraction bag 1C shown in FIG. It can be wide.

また、図１Ａに示したように、把持部の上辺１１ａが袋本体の上辺３ａよりも突出している場合に、把持部１１の袋本体底辺側の下辺１１ｂは、袋本体の面３ｘ内に収まるように形成されていることが好ましい。これにより、後述するように抽出バッグ１Ａを充填包装機にかけて工業的に製造する場合に縦シールをすることが容易となる。 Further, as shown in FIG. 1A, when the upper side 11a of the gripping portion protrudes from the upper side 3a of the bag body, the lower side 11b of the gripping portion 11 on the bottom side of the bag body fits within the surface 3x of the bag body. It is preferably formed as follows. This facilitates vertical sealing when the extraction bag 1A is industrially manufactured by using a filling and packaging machine as will be described later.

把持部１１には、該把持部１１を２つ折り可能とする袋本体上下方向の折れ線Ｌ１が形成されている。この折れ線Ｌ１は把持部１１の幅方向の中央部で把持部１１の上端から下端にかけて形成されている。一方、把持部１１には、把持部１１の引き起こしの軸となる袋本体幅方向の折れ線は形成されていない。なお、折れ線Ｌ１は、ミシン目、ハーフカット、筋押し等により形成することができる。 The gripping portion 11 is formed with a folding line L1 in the up-down direction of the bag body that allows the gripping portion 11 to be folded in two. The fold line L1 is formed from the upper end to the lower end of the gripping portion 11 at the central portion in the width direction of the gripping portion 11 . On the other hand, the gripping portion 11 does not have a folding line in the width direction of the bag body, which serves as an axis for pulling up the gripping portion 11 . In addition, the polygonal line L1 can be formed by perforation, half-cutting, creasing, or the like.

したがって、片手で把持部１１を摘まみ、折れ線Ｌ１で把持部１１を折り曲げつつ把持部１１を引き起こしていくと、把持部１１全体を容易に片手で２つ折りにすることができる。２つ折りにすることにより把持部１１はその上端から下端までがリジッドな棒状となり、図３に示すように、棒状になった把持部１１を袋本体上下方向に立てることができる。このとき、袋本体３の上端部は、平面図１Ａにおける貼着領域Ａの袋本体底辺側の縁辺Ａａが折り山となって折り畳まれ、袋本体の面３ｘから突出していた把持部１１の上辺１１ａが袋本体の背面３ｙに押し付けられることにより、袋本体３の上辺３ａも袋本体の背面３ｙに押し付けられ、上端部の折り畳まれた状態が安定する。また、袋本体３の折り畳まれた部分は、把持部１１と共に２つ折りになる。これにより、袋本体３内では抽出材料が充填されている部分の上方にスペースＳが形成される。したがって、図４に示すように、カップ１００に袋本体３を入れ、カップ１００内に注湯し、把持部１１で袋本体３を湯Ｗ内に浸漬させ、袋本体３内に湯Ｗを流入させることができる。また、把持部１１を上下させることにより袋本体３を湯Ｗ内で容易に上下させることができ、これにより袋本体３内のスペースＳに湯Ｗが入り易くなり、湯Ｗが抽出材料内に浸透し、抽出材料の抽出が促進される。 Therefore, by picking up the gripping portion 11 with one hand and raising the gripping portion 11 while bending the gripping portion 11 along the fold line L1, the entire gripping portion 11 can be easily folded in half with one hand. By folding in two, the grip portion 11 has a rigid bar shape from the top end to the bottom end, and as shown in FIG. At this time, the upper end of the bag main body 3 is folded at the edge Aa on the bag main body bottom side of the pasting area A in the plan view 1A to form a fold, and the upper edge of the grip portion 11 protruding from the surface 3x of the bag main body is folded. By pressing 11a against the back surface 3y of the bag body, the top edge 3a of the bag body 3 is also pressed against the back surface 3y of the bag body, stabilizing the folded state of the top end. Also, the folded portion of the bag body 3 is folded in two together with the grip portion 11 . As a result, a space S is formed in the bag body 3 above the portion filled with the extraction material. Therefore, as shown in FIG. 4, the bag body 3 is put into the cup 100, hot water is poured into the cup 100, the bag body 3 is immersed in the hot water W by the grip part 11, and the hot water W flows into the bag body 3. can be made In addition, by moving the grip part 11 up and down, the bag body 3 can be easily moved up and down in the hot water W, which makes it easier for the hot water W to enter the space S in the bag body 3, so that the hot water W can enter the brewing material. It penetrates and facilitates the extraction of the extraction material.

また、図５に示すように、２つ折りにした把持部１１から手を離してカップ１００内で抽出バッグ１Ａを放置し、把持部１１がカップ１００の内壁に寄り掛かり、該内壁で支持されるようにしてもよい。把持部１１の袋本体上下方向の長さを袋本体３の上辺３ａ近傍から底辺３ｂ近傍までとし、一般的なカップの径に対して十分長くすることにより、このようにカップ１００の内壁で把持部１１を支持することがきる。この場合、把持部１１は液面から突出しているが、袋本体３は湯に浸漬されている状態が維持されるので、抽出材料の抽出を進行させることができる。また、再度、把持部１１を把持して把持部１１を上下させることで袋本体３を湯Ｗ中で上下させて抽出を促進させることができ、また、把持部１１を引き上げることで袋本体３を湯Ｗから取り出すことも容易である。なお、本発明の抽出バッグでは、抽出材料が袋本体３内に密封された状態で使用されるので、抽出バッグの使用時に抽出材料が袋本体外に散らばることはない。 Also, as shown in FIG. 5, the hand is released from the grip portion 11 folded in two and the extraction bag 1A is left in the cup 100, and the grip portion 11 leans against the inner wall of the cup 100 and is supported by the inner wall. You may do so. By setting the length of the gripping portion 11 in the vertical direction of the bag body from the vicinity of the top side 3a to the vicinity of the bottom side 3b of the bag body 3 and making it sufficiently long with respect to the diameter of a general cup, the inner wall of the cup 100 is gripped in this way. Part 11 can be supported. In this case, the grasping portion 11 protrudes from the liquid surface, but the bag body 3 remains immersed in the hot water, so extraction of the extraction material can proceed. Further, by gripping the gripping portion 11 again and moving the gripping portion 11 up and down, the bag body 3 can be moved up and down in the hot water W to promote extraction. is also easy to take out from the hot water W. In addition, in the extraction bag of the present invention, the extraction material is sealed inside the bag body 3 when used, so that the extraction material does not scatter outside the bag body when the extraction bag is used.

これに対し、図２５に示す抽出バッグ１ｘのように、把持部１１に袋本体幅方向の折れ線Ｌ２が形成されていると、図２６に示すように折れ線Ｌ２が把持部１１の引き起こしの軸となる。この場合に、把持部１１を引き起こしつつ折れ線Ｌ１で把持部１１を２つ折りにしようとしても、折れ線Ｌ２の部分では把持部１１を２つ折りにすることが困難となる。また、折れ線Ｌ２で把持部１１を完全に折り曲げた後に、折れ線Ｌ１で把持部１１を折り曲げることはできるが、この折り曲げ作業は片手でできる作業ではなく、把持部１１の折り曲げ作業が煩雑となる。 On the other hand, as in the extraction bag 1x shown in FIG. Become. In this case, even if an attempt is made to fold the grip portion 11 in half along the fold line L1 while raising the grip portion 11, it is difficult to fold the grip portion 11 in half along the fold line L2. In addition, although the gripping part 11 can be folded along the folding line L1 after the gripping part 11 is completely folded along the folding line L2, this folding work cannot be done with one hand, and the folding work of the gripping part 11 is complicated.

後述するように把持部１１がＵ字形に形成されており、かつ図２７に示すように把持部１１に袋本体幅方向の折れ線Ｌ２が形成されている場合にも図２８に示すように折れ線Ｌ２が引き起こしの軸となる。そして把持部１１を引き起こしつつ折れ線Ｌ１で把持部１１を２つ折りにしようとすると、対向する把持部１１の内側端部１１ｃ同士がぶつかる。よって、この場合にも容易には２つ折りにすることができない。 As will be described later, even when the gripping portion 11 is formed in a U shape and the gripping portion 11 is formed with a folding line L2 in the width direction of the bag body as shown in FIG. is the triggering axis. When an attempt is made to fold the gripping portion 11 in two along the folding line L1 while raising the gripping portion 11, the inner ends 11c of the opposing gripping portions 11 collide with each other. Therefore, in this case as well, the paper cannot be easily folded in two.

（抽出材料）
袋本体３内に充填される抽出材料としては、コーヒー粉、紅茶、緑茶等の茶葉、漢方薬などを挙げることができる。一般に、コーヒー粉を袋本体３内に充填し、湯中に浸漬しようとすると、コーヒー粉に含まれる二酸化炭素により袋本体が浮き上がりやすいので、抽出し難い。しかし、本発明によれば、袋本体の一つの面に設けられた薄板状部材の把持部を把持することで、袋本体の反対面から袋本体を湯中に沈めたり、湯中で上下させたりすることが容易となるので、コーヒー粉を含む種々の抽出材料が、本発明の抽出バッグに充填する抽出材料として好適となる。 (extraction material)
Examples of the extraction material filled in the bag body 3 include coffee powder, tea leaves such as black tea and green tea, and herbal medicines. In general, when coffee grounds are filled in the bag body 3 and immersed in hot water, the carbon dioxide contained in the coffee grounds tends to lift the bag body, making extraction difficult. However, according to the present invention, by gripping the gripping portion of the thin plate-like member provided on one surface of the bag body, the bag body can be submerged in hot water from the opposite side of the bag body or moved up and down in hot water. Various brewing materials including ground coffee are suitable as brewing materials to be filled in the brewing bag of the present invention.

（袋本体）
袋本体３の形状は、本実施例では平袋としている。本発明において袋本体３の形状は平袋に限られず、例えば、底部又は側部にマチを有するガゼット袋としてもよい。袋本体の平面視の形状も矩形に限られず、円形などでもよい。 (bag body)
The shape of the bag body 3 is a flat bag in this embodiment. In the present invention, the shape of the bag body 3 is not limited to a flat bag, and may be, for example, a gusset bag having gussets on the bottom or sides. The shape of the bag body in a plan view is not limited to a rectangle, and may be a circle or the like.

袋本体３の正味の平面寸法は、抽出バッグを用いて抽出液を得る場合に使用するカップ又は容器の大きさに応じて適宜設定することができる。例えば、袋本体３を市販のコーヒーカップに適合した大きさにすればよい。 The net planar dimension of the bag body 3 can be appropriately set according to the size of the cup or container used when obtaining the extract using the extraction bag. For example, the size of the bag body 3 may be adjusted to fit a commercially available coffee cup.

（通水濾過性シート）
袋本体３を形成する通水濾過性シートとしては、抽出材料の抽出に使用できるように通水性及び濾過性を有するものを種々使用することができ、抽出材料の種類に応じて通水濾過性シートの構成材料も適宜選択することができる。例えば、一般に、飲料を抽出するための通水濾過性シートとしては、ポリエステル、ナイロン、ポリエチレン、ポリプロピレン、ビニロン等の合成繊維、レーヨン等の半合成繊維、コウゾ、ミツマタ等の天然繊維の単独又は複合繊維からなる織布あるいは不織布、マニラ麻、木材パルプ、ポリプロピレン繊維等からなる混抄紙、ティーバッグ原紙等の紙類が知られており、本発明においてもこれらを使用することができる。抽出バッグの使用後の廃棄性の点からは、通水濾過性シートに生分解性繊維を含有させることが好ましい。生分解性繊維としては、ポリ乳酸、ポリブチレンサクシネート、ポリエチレンサクシネート等を挙げることができる。また、袋本体内の抽出材料の状態がわかるように、通水濾過性シートに透明性をもたせる点からは、無機系顔料の含有量を低減させること又は無機系顔料が含まれないようにすることが好ましい。 (Water permeable filterable sheet)
As the water-permeable and filterable sheet forming the bag body 3, various types of water-permeable and filterable sheets can be used so that they can be used for extraction of the extraction material. The constituent material of the sheet can also be selected as appropriate. For example, in general, water permeable and filterable sheets for extracting beverages are made of synthetic fibers such as polyester, nylon, polyethylene, polypropylene and vinylon, semi-synthetic fibers such as rayon, and natural fibers such as paper mulberry and mitsumata, either alone or in combination. Papers such as woven fabrics or non-woven fabrics made of fibers, mixed papers made of manila hemp, wood pulp, polypropylene fibers, etc., base paper for tea bags, etc. are known, and these can also be used in the present invention. From the point of disposal after use of the extraction bag, it is preferred that the water permeable filterable sheet contains biodegradable fibers. Examples of biodegradable fibers include polylactic acid, polybutylene succinate, polyethylene succinate, and the like. In addition, in order to give transparency to the water-permeable filter sheet so that the state of the extraction material in the bag body can be seen, the content of inorganic pigments should be reduced or inorganic pigments should not be included. is preferred.

また、ドリップタイプの抽出バッグでは抽出材料へ直接的に湯が注がれるのに対し、本発明の抽出バッグでは、必ず通水濾過性シートを通して抽出材料へ湯が供給されるため、抽出材料の粉漏れが生じない限りで、ドリップタイプの抽出バッグで使用される通水濾過性シートよりも目の粗いものを使用することが好ましい。例えば、コーヒー粉を抽出材料とする場合、通水濾過性シートの通気性は１３０～６００ｃｍ3／ｃｍ2／ｓｅｃ（ＪＩＳ Ｌ１０９６通気性Ａ法（フラジール形通気性試験機を用いる方法））とすることができる。 In addition, in the drip type extraction bag, hot water is directly poured onto the extraction material. As long as powder leakage does not occur, it is preferable to use a more open mesh than the water permeable filter sheet used in the drip type extraction bag. For example, when coffee grounds are used as the extraction material, the air permeability of the water-permeable filter sheet should be 130 to 600 cm 3 /cm 2 /sec (JIS L1096 air permeability method A (method using a Frazier air permeability tester)). be able to.

（薄板状部材）
薄板状部材１０は撥水性を有するものが好ましく、表面に樹脂をラミネートした板紙、プラスチックシート等の薄板状材料の打ち抜きにより形成することができる。抽出バッグ１Ａ使用後の廃棄性の点からは、ポリ乳酸、ポリブチレンサクシネート、ポリエチレンサクシネート等の生分解性材料から形成したものが好ましい。 (Thin plate member)
The thin plate-like member 10 preferably has water repellency, and can be formed by punching out a thin plate-like material such as paperboard or plastic sheet laminated with a resin on the surface. From the standpoint of disposal after use of the extraction bag 1A, it is preferable to use a biodegradable material such as polylactic acid, polybutylene succinate, or polyethylene succinate.

（使用方法）
抽出バッグ１Ａの包装、流通形態としては、図１Ａに示したように、薄板状部材１０が袋本体３上で扁平化している状態が好ましい。そこで、この状態の抽出バッグ１Ａを出発状態として、抽出バッグ１Ａから抽出材料の抽出を行う方法としては、まず、図２に示すように、袋本体３から薄板状部材１０の把持部１１を引き起こし、さらに図３に示すように、把持部１１を折れ線Ｌ１で２つ折りにし、把持部１１がほぼ袋本体上下方向となるように把持部１１を引き起こし、図４に示すように、袋本体３をカップ１００等の容器に入れて注湯し、把持部１１で袋本体３を湯内に押し込んで袋本体３を浸漬させる。 (how to use)
As for the packaging and distribution form of the extraction bag 1A, it is preferable that the thin plate member 10 is flattened on the bag body 3 as shown in FIG. 1A. Therefore, as a method of extracting the extraction material from the extraction bag 1A with the extraction bag 1A in this state as the starting state, first, as shown in FIG. Further, as shown in FIG. 3, the gripping portion 11 is folded in half along the folding line L1, and the gripping portion 11 is lifted so that the gripping portion 11 is substantially in the vertical direction of the bag body, and the bag body 3 is folded as shown in FIG. Hot water is poured into a container such as a cup 100, and the bag body 3 is immersed by pushing the bag body 3 into the hot water with the grip part 11.例文帳に追加

把持部１１を２つ折りにしたことで袋本体３の上辺も２つ折りになり、袋本体３の内部にスペースが形成されるので、湯は袋本体３の表面を流れるだけでなく、袋本体内に流入しやすくなっている。そこで、把持部１１を上下させることにより湯中の袋本体３を上下させると、湯の袋本体３内への流入と袋本体３からの排出が繰り返されるので抽出が促進される。 By folding the grip part 11 in two, the upper side of the bag body 3 is also folded in two, and a space is formed inside the bag body 3. It is easier to flow into Therefore, when the bag body 3 in the hot water is moved up and down by moving the grip part 11 up and down, hot water flows into the bag body 3 and is discharged from the bag body 3 repeatedly, thereby promoting extraction.

あるいは、湯の入ったカップ１００に抽出バッグを入れ、同様に抽出バッグ１Ａを上下させて抽出する。 Alternatively, an extraction bag is placed in a cup 100 filled with hot water, and the extraction bag 1A is similarly moved up and down for extraction.

また、図５に示すように、袋本体３が湯に浸漬した状態で把持部１１から手を離し、把持部１１をカップ１００の内壁で支持させて、抽出バッグ１Ａを放置してもよい。放置している間に抽出を進めることができる。また、再度把持部１１を把持し、把持部１１を上下させることで袋本体３を湯中で上下させ、抽出を促進させてもよい。
上述した抽出方法は冷水で行ってもよい。 Alternatively, as shown in FIG. 5, when the bag body 3 is immersed in hot water, the hand may be released from the grip portion 11, the grip portion 11 may be supported by the inner wall of the cup 100, and the extraction bag 1A may be left alone. Extraction can proceed while left unattended. Alternatively, the gripping portion 11 may be gripped again and moved up and down to move the bag body 3 up and down in hot water to promote extraction.
The extraction method described above may be performed with cold water.

抽出後は、把持部１１を把持してカップ１００内から容易に抽出バッグ１Ａを取り出すことができる。 After the extraction, the extraction bag 1A can be easily taken out from the cup 100 by gripping the grip portion 11. FIG.

こうしてこの抽出バッグ１Ａによれば、簡便に迅速に所望の濃さの抽出液を得ることができる。 Thus, according to this extraction bag 1A, an extract having a desired concentration can be obtained simply and quickly.

（製造方法）
抽出バッグ１Ａの製造方法としては、例えば、図８に示すように、長尺の通水濾過性シート２１の短尺方向に薄板状部材１０の折れ線Ｌ１を合わせた向きで、通水濾過性シート２１に薄板状部材１０を所定間隔で並べて貼着した抽出バッグ製造用シート２０を用意する。図中、二点鎖線で挟まれた領域が抽出バッグ１個分の製造に使用されることとなる。 (Production method)
As a method of manufacturing the extraction bag 1A, for example, as shown in FIG. A sheet 20 for manufacturing an extraction bag is prepared by arranging and adhering thin plate-like members 10 at predetermined intervals. In the figure, the area sandwiched by two-dot chain lines is used for manufacturing one extraction bag.

この抽出バッグ製造用シート２０を包装充填機で用いることにより抽出バッグ１Ａを連続的に製造することができる。この場合、まず図９に示すように、抽出バッグ製造用シート２０の長手方向の両側辺を重ね合わせるように２つ折りにし、その長手方向の側辺同士を溶着して縦シール２２を形成することにより筒状体２４を形成する。次に、筒状体２４を短手方向に溶着する横シール２３の形成と袋本体３内への抽出材料Ｍの充填とを交互に繰り返すことにより抽出バッグ１Ａの袋本体３の側辺で抽出バッグ１Ａが上下に繋がった抽出バッグ連続体を製造し、これを個々の抽出バッグに切り離して抽出バッグ１Ａを得る。あるいは、筒状体の短手方向の横シール２３の形成時に溶断も同時に行い、個々に切り離された抽出バッグ１Ａを連続的に製造する。 By using this brewing bag manufacturing sheet 20 in a packaging and filling machine, the brewing bag 1A can be continuously manufactured. In this case, first, as shown in FIG. 9, the sheet for manufacturing an extraction bag 20 is folded in two so that both sides in the longitudinal direction are overlapped, and the longitudinal sides are welded to each other to form a vertical seal 22 . to form the cylindrical body 24 . Next, by alternately repeating the formation of the lateral seal 23 that welds the cylindrical body 24 in the transverse direction and the filling of the extraction material M into the bag body 3, extraction is performed on the side of the bag body 3 of the extraction bag 1A. A series of extraction bags in which the bags 1A are connected vertically is manufactured, and is cut into individual extraction bags to obtain the extraction bags 1A. Alternatively, when forming the lateral seals 23 in the lateral direction of the cylindrical body, fusion cutting is also performed at the same time to continuously manufacture the individually separated extraction bags 1A.

（変形態様）
本発明の抽出バッグは種々の変更点をもつことができる。例えば、図１０に示した平面図の抽出バッグ１Ｄは、図１Ａに示した平面図の抽出バッグ１Ａに対して、薄板状部材１０が袋本体上下方向に伸びた補強部１２を有する点が異なっている。より具体的には、補強部１２は把持部１１の外周部に形成され、補強部１２の上端が把持部１１と袋本体幅方向の折れ線Ｌ３を介して繋がっており、補強部１２の略全面が袋本体３に貼着している。なお、折れ線Ｌ３を介して補強部１２を把持部１１と連続させず、補強部１２と把持部１１とを離間させて補強部１２を設けても良いが、把持部１１と補強部１２を一枚の薄板状材料の打ち抜きにより形成し、これらを袋本体３の片面に貼着するにあたり、これらの貼着位置のずれをなくす点から補強部１２は把持部１１に折れ線Ｌ３を介して連続させることが好ましい。 (Modification mode)
The extraction bag of the present invention can have various modifications. For example, the brewing bag 1D shown in the plan view of FIG. 10 differs from the brewing bag 1A shown in the plan view of FIG. ing. More specifically, the reinforcing portion 12 is formed on the outer peripheral portion of the gripping portion 11, and the upper end of the reinforcing portion 12 is connected to the gripping portion 11 via a fold line L3 in the width direction of the bag body. is adhered to the bag body 3. The reinforcing portion 12 may be separated from the gripping portion 11 without connecting the reinforcing portion 12 to the gripping portion 11 via the broken line L3. The reinforcing portion 12 is formed by punching out a sheet of thin plate-like material, and when these are attached to one side of the bag body 3, the reinforcing portion 12 is connected to the grip portion 11 via the folding line L3 in order to eliminate the deviation of the attaching position. is preferred.

補強部１２を有する抽出バッグ１Ｄでは、把持部１１を引き起こし、袋本体３をカップ等のカップ１００内で上下させた場合の袋本体３の潰れ方を少なくすることができ、袋本体３に充填されている抽出材料の上に常時スペースを確保しておくことができる。よって、袋本体３内に流れ込む湯量の変化を低減し、抽出速度を安定させることができる。また、図１１に示すように、カップ１００内で把持部１１から手を離した場合にカップ内壁で支持される把持部１１の液面に対する位置や傾きを安定化させることができる。特に、図１２に示すように、トールタイプのカップ１００で抽出を行う場合に、把持部１１から手を離しても把持部１１がカップ内に過度に沈み込むことがなく、再度把持部１１を把持することが容易になる。 The extraction bag 1D having the reinforcing portion 12 can reduce the crushing of the bag body 3 when the gripping portion 11 is raised and the bag body 3 is moved up and down in a cup 100 such as a cup, and the bag body 3 is filled. Space can be reserved at all times on top of the brewing material being used. Therefore, the change in the amount of hot water flowing into the bag body 3 can be reduced, and the extraction speed can be stabilized. In addition, as shown in FIG. 11, when the hand is released from the gripping portion 11 in the cup 100, the position and inclination of the gripping portion 11 supported by the inner wall of the cup with respect to the liquid surface can be stabilized. In particular, as shown in FIG. 12, when performing extraction with a tall type cup 100, even if the hand is released from the grip portion 11, the grip portion 11 does not excessively sink into the cup, and the grip portion 11 is released again. Easier to grip.

把持部１１の外周部に補強部１２を設ける場合に、図１３に示す抽出バッグ１Ｅのように、補強部１２は袋本体３に貼着するが、把持部１１の袋本体３への貼着を省略することができる。この場合にも把持部１１の上部が袋本体３の一つの面３ｘの上部に固定され、把持部の下部がその面３ｘから引き起こし可能となるので、本発明の効果を得ることができる。 When the reinforcing portion 12 is provided on the outer peripheral portion of the grip portion 11, the reinforcing portion 12 is attached to the bag body 3 as in the extraction bag 1E shown in FIG. can be omitted. Also in this case, the upper part of the grip part 11 is fixed to the upper part of one surface 3x of the bag body 3, and the lower part of the grip part can be lifted from the surface 3x, so that the effects of the present invention can be obtained.

図１４に示す抽出バッグ１Ｆのように、把持部１１をＵ字形に形成してもよい。この把持部１１は、Ｕ字形の把持部の上端部が袋本体３の上辺３ａに沿って屈曲しており、この上辺３ａに沿った部分が袋本体の面３ｘと貼着している。また、該把持部１１を袋本体上下方向に折る折れ線Ｌ１がＵ字形の把持部１１の下方で該把持部１１を二等分するように形成されている。 As with the extraction bag 1F shown in FIG. 14, the grip portion 11 may be formed in a U shape. The upper end of the U-shaped grip portion 11 is bent along the upper edge 3a of the bag body 3, and the portion along the upper edge 3a is adhered to the surface 3x of the bag body. Further, a folding line L1 for folding the gripping portion 11 in the vertical direction of the bag body is formed so as to bisect the gripping portion 11 below the U-shaped gripping portion 11 .

図１５に示すように、この抽出バッグ１Ｆの把持部１１を袋本体上下方向の折れ線Ｌ１で２つ折りにするにあたり、折れ線Ｌ１の長さが図１Ａに示した抽出バッグ１Ａよりも短いので、図１Ａに示した抽出バッグ１Ａよりも僅かな力で把持部１１を２つ折りにすることができる。 As shown in FIG. 15, when the grip portion 11 of the extraction bag 1F is folded in two along the vertical folding line L1 of the bag body, the length of the folding line L1 is shorter than that of the extraction bag 1A shown in FIG. The grip part 11 can be folded in two with less force than the extraction bag 1A shown in 1A.

また、把持部１１を２つ折りにした以降は、図１Ａに示した抽出バッグ１Ａと同様に袋本体３内の抽出材料の抽出を行うことができ、図１６に示すように、カップ１００内においた抽出バッグ１Ｆの把持部１１から手を離すこともできる。 Further, after the grip part 11 is folded in two, the extraction material in the bag body 3 can be extracted in the same manner as the extraction bag 1A shown in FIG. It is also possible to release the hand from the grasping portion 11 of the extraction bag 1F.

把持部１１をＵ字形に形成するにあたり、図１７に示す抽出バッグ１Ｇのように、Ｕ字形の把持部１１の内周部分に切り欠き１３を形成してもよい。これにより、図１８に示すように、２つ折りにした把持部１１の切り欠き１３をカップ１００の開口部壁に掛けることが可能となる。 When forming the gripping portion 11 into a U shape, a notch 13 may be formed in the inner peripheral portion of the U-shaped gripping portion 11 as in the extraction bag 1G shown in FIG. As a result, as shown in FIG. 18, the notch 13 of the grip portion 11 folded in two can be hung on the opening wall of the cup 100 .

また、図１９に示す抽出バッグ１Ｈのように、Ｕ字形の把持部１１の外周部に補強部１２を形成してもよい。この場合もＵ字形の把持部１１の袋本体の上辺３ａに沿った部分と補強部２の上端とを折れ線Ｌ３を介して連続させることが好ましい。 Further, as in an extraction bag 1H shown in FIG. 19, a reinforcing portion 12 may be formed on the outer peripheral portion of the U-shaped grip portion 11. As shown in FIG. Also in this case, it is preferable that the portion of the U-shaped gripping portion 11 along the upper side 3a of the bag body and the upper end of the reinforcing portion 2 are connected via the fold line L3.

図２０に示す抽出バッグ１Ｉのように、把持部１１をＯ字形（即ち、環状）に形成してもよい。また、把持部１１をＯ字形に形成する場合、図２１に示す抽出バッグ１Ｊのように、把持部１１の内側に、袋本体３の面３ｘと貼着した補強部１２を設けても良い。この場合、補強部１２の上端と、把持部１１の環状内の上端との間には間隙２５があくように薄板状部材に開口部を設けることが好ましい。これにより、図２２に示すように、把持部１１を袋本体から引き上げ、２つ折りにすることができ、また、袋本体３の形状が過度に潰れないようにすることができる。これに対し、Ｏ字形の把持部１１の内部の間隙２５を無くし、把持部１１の内部の全面を補強部１２として袋本体の面３ｘに貼着すると、袋本体３から引き上げた把持部１１を折れ線Ｌ１で２つ折りにすることができなくなる。 As with the extraction bag 1I shown in FIG. 20, the grip portion 11 may be formed in an O shape (that is, annular). When the gripping portion 11 is formed in an O shape, a reinforcing portion 12 attached to the surface 3x of the bag body 3 may be provided inside the gripping portion 11, as in the extraction bag 1J shown in FIG. In this case, it is preferable to provide an opening in the thin plate-like member so that a gap 25 is formed between the upper end of the reinforcing portion 12 and the upper end of the grip portion 11 in the ring. As a result, as shown in FIG. 22, the grip portion 11 can be pulled up from the bag body and folded in two, and the shape of the bag body 3 can be prevented from being excessively crushed. On the other hand, if the gap 25 inside the O-shaped gripping portion 11 is removed and the entire inner surface of the gripping portion 11 is adhered to the surface 3x of the bag body as the reinforcing portion 12, the gripping portion 11 lifted up from the bag body 3 can be attached. It becomes impossible to fold in half along the folding line L1.
