Description

本発明は飲用容器上に置きセットして使用する、レギュラーコーヒー等の使い捨てタイプのドリップ式抽出バッグであり、通水性濾過性を有したシート材料で構成した、上方に開口部を有した濾過袋であり、この濾過袋に防水加工をした厚紙等の部材で構成した支持体を取り付て設けており、カップ等の飲用容器の口部上に、この支持体で濾過袋を支持し定置させており、この袋内のコーヒー粉に、お湯を注ぎ入れ抽出ドリップし使用するドリップ抽出バッグに関するものである。 The present invention is a disposable type drip-type extraction bag such as regular coffee, which is set and used on a drinking container, and is a filter bag having an opening portion above, which is made of a sheet material having a water-permeable filterability. The filter bag is provided with a support made of waterproof cardboard or other member, and the filter bag is supported and set on the mouth of a drinking container such as a cup. The present invention relates to a drip extraction bag which is used by pouring hot water into the coffee powder in the bag to perform extraction drip.

従来、濾過袋をカップ口部上に位置させ定置させるために、濾過袋に取り付けた支持体は、柔軟性のある濾過袋を硬性のある支持体でカップ口部上にカップ口部を支持体が、とらえ濾過袋の袋形を形成しながら、カップ口部上に濾過袋を保持するものであるが、この支持体を多く使用できるタイプの抽出バッグは、濾過袋をカップ上に高く位置させカップ内の湯面に接する事なくドリップ性が高いが、他方で製袋方式である抽出バッグは、濾過シートにあらかじめ支持体を取り付けて貼着しており、このシート状の濾過袋を二つ折りにして、折り目以外の三辺の端部を封じ、中にコーヒー粉を充墳しており、この製袋方式は三辺を封じる工程がある為に、この三辺の端部どうしを貼着する為のスペースを確保しなければならず、このスペースの内側の範囲内だけに支持体の大きさに限定されるため、大きな支持体面積を使用できず、カップ口部上に高く濾過袋を浮かせドリップ性を高める事はできずカップの口部を、とらえ濾過袋をカップ内に位置させる、つり下げ方式的になる傾向にあり、袋部が半分お湯に浸す半分ドリップの方式になり完全ドリップには不向きであるなど課題や制約が多かったが、濾過袋形より外側に支持体が大きく伸び出る事のできるタイプに比較し製袋方式タイプは設備費が１０分の１程度と商品コストの面では大きな利点があった。 Conventionally, in order to position the filter bag on the cup mouth part and place it in place, the support attached to the filter bag is a flexible filter bag which is a rigid support and the cup mouth part is supported on the cup mouth part. However, while the filter bag is held on the cup mouth while forming a trapezoidal filter bag, this type of extraction bag that can use many supports has the filter bag placed higher on the cup. The extraction bag, which has a high drip property without coming into contact with the surface of the water in the cup, is a bag-making method.The support is attached to the filter sheet in advance and the filter bag is folded in two. Then, the edges of the three sides other than the fold line are sealed, and the coffee powder is filled inside.Since this bag-making method has a step of sealing the three sides, the edges of the three sides are stuck together. Space must be secured, and since the size of the support is limited only to the inside of this space, a large support area cannot be used and a high filtration bag is placed above the cup mouth. It is not possible to raise the drip property by floating and catch the mouth of the cup and position the filtration bag inside the cup, there is a tendency to be a hanging system, the bag part is a half drip method soaking in hot water There were many problems and restrictions such as being unsuitable for, but compared to the type that the support can greatly extend outside the filter bag type, the bag making method type has about 1/10 of the equipment cost and the product cost. In terms of aspect, there was a great advantage.

特許第２５０５９５９号Patent No. 2505959 特開平１１−１７８７２０Japanese Patent Laid-Open No. 11-178720 特許第３７２７２７０号Patent No. 3727270 特開２００４−１３０１０４JP-A-2004-130104 特開２００９−９６５０７Japanese Patent Laid-Open No. 2009-96507

それには次のような問題点があった。
（イ）濾過袋をカップ上に位置させるタイプの（特開２００４−１３０１０４）や（特開２００９−９６５０７）は袋の位置が高く、カップ内のお湯に袋の下部が浸る事がなくドリップ性は良いが、全体に大型のコーヒーバッグになり又、生産設備も大規模となるため高コストとなる。
（ロ）それに比較し（特許第２５０５９５９号）や（特開平１１−１７８７２０）や（特許第３７２７２７０号）などの製袋方式の場合では生産設備が１０分の１程度であるため低コストな利点があるが、製袋方式の特徴として濾過性を有したシート材料に、あらかじめ支持体を貼り付けてある状態のシート材料を二つ折りにしながら合わせる三辺の端部を封じながら構成する袋内にコーヒー粉を充墳して行く方式であるため、封じる三辺の端部のスペースをシート材料の周囲に残した内側の範囲内の大きさの支持体であるため、この限られた面積とサイズの支持体で立体的に全体形を構成し安定させて袋部をカップ内のお湯に浸らない様に濾過袋をカップ上に高く位置させ保持する構造を構成しドリップ性を高めることは難しかった。
（ハ）又、（特許第３７２７２７０号）は支持体の折り目を伸ばしカップ上に台形型を構成し、（特開２００４−１３０１０４）や（特開２００９−９６５０７）は支持体で舟型を形成し、それぞれカップ上に袋部の口を開き保持しているが、（特許第３７２７２７０号）は支持体の折り目を伸ばし固定するために折り返し辺で支持体の折り目を伸ばし固定しているが折り返し方式では折り返し辺が元に戻る事があり又、（特開２００４−１３０１０４）や（特開２００９−９６５０７）は三角型で小型の折り込み部で支持体を舟型に開き固定しているが、この折り込み方式の場合折り込んだ状態の固定力は弱く又、折り込んだ反発力で固定した状態を保つためその反発力を超える力が作用すると折り込んだ方向にそのまま折れ曲がり固定できなくなる課題があった。It had the following problems.
(A) In the type of (Japanese Patent Application Laid-Open No. 2004-130104) and (Japanese Patent Application Laid-Open No. 2009-96507) in which the filter bag is located on the cup, the bag position is high, and the lower part of the bag is not soaked in the hot water in the cup, and the drip property is maintained. Although it is good, it will be a large coffee bag as a whole, and the production equipment will be large-scaled, resulting in high cost.
(B) In comparison with that, in the case of the bag manufacturing method such as (Japanese Patent No. 2505959), (Japanese Patent Laid-Open No. 11-178720) and (Japanese Patent No. 3727270), the production facility is about 1/10, and the cost is low. However, as a characteristic of the bag making method, the sheet material having the filterability is combined with the sheet material in the state where the support is attached in advance while folding it in half. Since it is a method of filling coffee grounds, it is a support of a size within the inside range that leaves spaces at the ends of the three sides to be sealed around the sheet material, so this limited area and size It was difficult to enhance the drip property by constructing a structure in which the filter bag is positioned high above the cup so that the bag part does not get soaked in the hot water in the cup and is stabilized by constructing the whole shape three-dimensionally with the support of ..
(C) Also, (Patent No. 3727270) extends the folds of the support to form a trapezoidal mold on the cup, and (JP-A-2004-130104) and (JP-A-2009-96507) form a boat-shaped support. Then, the mouth of the bag portion is opened and held on each cup, but in (Patent No. 3727270), the folds of the support are extended and fixed at the folding sides in order to extend and fix the folds of the support. In the method, the folded side may return to the original, and in (JP-A-2004-130104) and (JP-A-2009-96507), the support is opened and fixed in a boat shape by a small fold portion having a triangular shape. In the case of this folding method, the fixing force in the folded state is weak, and in order to maintain the fixed state by the folded repulsive force, there is a problem that if a force exceeding the repulsive force acts, it cannot be bent and fixed as it is in the folded direction.

本発明では、通水性濾過性を有するシート材料１に、あらかじめ厚紙等に防水加工をして構成した支持体２をシート材料１の周囲に端部３を、のこし設けて各、貼着部２２でシート材料１に支持体２を貼着し一体に取り付けている、この支持体２を貼り付けたシート材料１全体を二つ折りにする二つ折り部線１８を支持体２の中央に左右に貫通して設けている、この支持体２は箱型を構成する底面として支持柱１１を有し前後の側壁は支持辺６が構成し左右側壁は側辺５が構成しており支持体２はシート材料１で構成する袋部２５の外面側に貼着されて全体を支持体２の二つ折部線１８から折り曲げ、シート材料１側の他の三辺の端部３どうしを一体にして封じている全体構成とした製袋構造である、支持柱１１は前後方向に構え前部側の端には左折り目１９と後部側の端には右折り目２１を有し各折り目から、前後側の側壁を構成する支持辺６が伸び出て形成し有しており、この支持辺６は上部側の左右には端部折り目２０から、それぞれ側辺５が伸びて設け有しており、この側辺５は、さらに下方に伸び袋部２５の上方口２４から底部側まで位置して、左右側の側壁を構成し、さらに、この支持辺６の下部側には左右に伸び出た支持アーム１０を、それぞれ有し、その下端部には外ガード７と内ガード８、その間に設けた受け部９からなる受け部を構成し設け有している、さらに支持柱１１は、左折り目１９と右折り目２１の間に構え支持柱１１の両サイド側に設けた各折り曲げ線１３から両サイド方向にそれぞれ伸び出た折り下げ辺１２を構成し設けており、この折り下げ辺１２の巾は左折り目１９から右折り目２１までの巾の折り下げ辺１２となっている、又支持柱１１はシート材料１で構成した袋部２５の底部の下面側の中央部に位置し、その両サイド側には袋部２５の底部側の左右の下端にポケット部１６を構成する角部１５が位置し有している又、この折り下げ辺１２は各、支持柱１１側に、折り曲げ線１３から伸び出た凸部１４を設けている、袋部２５を構成するシート材料１には上方口２４を構成するための、ミシン目４を上部側の端部３の内側の位置で左右巾に貫通したミシン目４を設けている。In the present invention, the sheet material 1 having water-permeable filterability is provided with the support body 2 which is made by waterproofing thick paper or the like in advance, and the end portion 3 is provided around the sheet material 1 by a strainer so that the adhesive portions 22 The support 2 is attached to and integrally attached to the sheet material 1 with the sheet material 1 to which the support 2 is attached. This support 2 has a support column 11 as a bottom surface forming a box shape, and front and rear side walls are formed by support sides 6 and left and right side walls are formed by side sides 5, and the support 2 is a sheet. It is attached to the outer surface side of the bag portion 25 made of the material 1 and the whole is bent from the double-folded line 18 of the support body 2 and the end portions 3 of the other three sides on the sheet material 1 side are integrally sealed. The support column 11 is a bag-making structure having the entire structure. The support column 11 is held in the front-rear direction and has a left fold line 19 at the front end and a right fold line 21 at the rear end. The supporting sides 6 constituting the above are formed so as to extend, and the supporting sides 6 are provided on the upper left and right sides from the end folds 20, respectively, and the side sides 5 respectively extend. 5 further extends downward and is located from the upper opening 24 of the bag portion 25 to the bottom side to form left and right side walls, and further, on the lower side of the support side 6, the support arm 10 extending left and right is provided. , Each of which has a receiving portion composed of an outer guard 7 and an inner guard 8 and a receiving portion 9 provided between the outer guard 7 and the inner guard 8, and the supporting column 11 further includes a left fold line 19 and a right fold line. 21. The folding sides 12 extending in the both side directions from the folding lines 13 provided on both sides of the holding support column 11 are formed between the folding lines 21, and the width of the folding side 12 is set to the left fold line 19. To the right fold line 21 and the supporting column 11 is located at the center of the bottom surface of the bottom of the bag portion 25 made of the sheet material 1 and has a bag on both sides. Corners 15 that form pockets 16 are located at the left and right lower ends on the bottom side of the portion 25. Further, each of the folding sides 12 is a projection extending from the folding line 13 toward the support column 11 side. The perforation 4 which penetrates the perforation 4 in the left-right width at a position inside the end 3 on the upper side for forming the upper opening 24 in the sheet material 1 forming the bag portion 25 in which the portion 14 is provided. Is provided.

支持柱１１は左折り目１９と右折り目２１の間に細長で巾の狭い形状であり、支持柱１１の両サイドに有した折り曲げ線１３から、それぞれ伸び出た折り下げ辺１２は、左折り目１９と右折り目２１の巾で両サイド方向に各、長く伸び出た大きな折り下げ辺１２を構成している。 The support column 11 has a narrow and narrow shape between the left fold line 19 and the right fold line 21. The folding lines 12 extending from the folding lines 13 on both sides of the support column 11 have the left fold lines 19 and 19 respectively. The width of the right fold 21 constitutes a large fold-down side 12 extending in each side in both sides.

（Ａ）箱形を形成する支持体２の底部を構成する支持柱１１の前後に設けた支持辺６の下端部に設けたカップの口部受け部でカップ１７の口部を、とらえているため支持柱１１はカップ１７の口部の高さに位置して袋部２５の底面を下から支えているため袋部２５の底部がカップ１７内の湯面上に浮かせて保持できる。
（Ｂ）支持柱１１の両サイドの折り下げ辺１２は二つ折り部線１８の折り目を伸ばしながら支持柱１１と下方向きのコの字型の箱状の形状を形成しているため支持柱１１が袋部２５の重量を支える高い強度を構成できる。
（Ｃ）支持体２の中央の二つ折り部線１８を伸ばし支持柱１１を平たく維持するための両サイドの折り下げ辺１２が支持柱１１の左折り目１９と右折り目２１の間の巾で構成した広巾であり又、さらに支持柱１１が前後に細長い形状で巾を狭くして構えていることで両サイド方向に折り下げ辺１２は長く伸ばして構成できるため折り下げ辺１２は大型の折り下げ辺１２となり二つ折り部線１８を伸ばし固定する作用が高くなる。
（Ｄ）支持体２で箱形を形成したとき下方に折り下げた折り下げ辺１２の外側にポケット部１６を構成し設け有しており、このポケット部１６の中にコーヒー粉やお湯が入ることで折り下げ辺１２は折り下げた後は元に戻らなくなり固定できる。
（Ｅ）支持柱１１は細長で巾の狭い形状で袋部２５の底部の中央部だけを下から支えるため袋部２５の底部側の左右の角部１５を下方に下げてポケット部１６を支持柱１１の両サイド側で折り下げ辺１２の外側に位置させ構成できる。(A) The mouth portion of the cup 17 is caught by the mouth portion receiving portion of the cup provided at the lower end portion of the support side 6 provided before and after the support column 11 that constitutes the bottom portion of the support body 2 forming the box shape. Therefore, since the support column 11 is located at the height of the mouth of the cup 17 and supports the bottom surface of the bag portion 25 from below, the bottom portion of the bag portion 25 can be floated and held on the molten metal surface in the cup 17.
(B) Since the folded-down sides 12 on both sides of the support column 11 form a downward U-shaped box-like shape with the support column 11 while extending the fold line of the folding line 18, Can construct high strength to support the weight of the bag portion 25.
(C) Folding sides 12 on both sides for extending the center fold line 18 of the support 2 and keeping the support pillar 11 flat are configured with a width between the left fold 19 and the right fold 21 of the support pillar 11. In addition, since the supporting column 11 is slender in the front and rear direction and has a narrow width, the folding side 12 can be extended and extended in both side directions. It becomes the side 12, and the action of stretching and fixing the half-folded part line 18 is enhanced.
(D) A pocket 16 is formed and provided outside the folding side 12 folded downward when the support 2 forms a box shape, and coffee powder or hot water enters the pocket 16. As a result, the folding side 12 can be fixed without returning to the original state after being folded.
(E) The support column 11 has an elongated and narrow shape, and supports only the central portion of the bottom of the bag portion 25 from below, so that the left and right corners 15 on the bottom side of the bag portion 25 are lowered to support the pocket portion 16. It can be configured by being positioned outside the folding side 12 on both sides of the pillar 11.

Form for Carrying Out the Invention

以下、本発明の実施形態について説明する。
（１）通気性濾過性を有するシート材料１に、あらかじめ厚紙等に防水加工をして構成した支持体２をシート材料１の周囲に端部３をのこし設けて各貼着部２２でシート材料１に支持体２を貼着し一体に取り付けている。
（２）この支持体２を貼り付けたシート材料１を二つ折りにするための二つ折り部線１８を支持体２の中央に左右に貫通して設けている。
（３）この支持体２は箱形を形成するための、底面を構成する支持柱１１を設けており、これはシート材料１で袋部２５を形成したとき袋部２５の底部を下から支え保持するもので、袋部２５の底部の下面に位置し底部の中央部を前後に巾の狭い細長い形状で構え支えている支持柱１１である。
（４）この支持柱１１は縦方向に細長く巾を狭くして構え左右に大きなスペースを構成して、支持柱１１の、この両サイドに設けたスペースに折り曲げ線１３を介しそれぞれ両サイド方向に各長く伸び出させた左折り目１９と右折り目２１の巾での大型の折り下げ辺１２を構成させて各設け有しており、さらに支持柱１１の、この前後方向に細長い前部側の端部には左折り目１９と後部側の端には右折り目２１を有し各折り目から、さらに前後側の側壁を構成する支持辺６が伸び出て各有している。
（５）この支持辺６の上部側の左右には端部折り目２０を介し、それぞれ側辺５を設けており、この側辺５は、さらに下方に伸び袋部２５の上方口２４から底部側まで伸びており袋部２５と支持体２が箱型を構成したときの左右側の側壁を形成するものである。
（６）さらに、この支持辺６の両側部側には左右に伸び出た支持アーム１０を、それぞれ有し、その下端部にはカップの口部を取らえ受けるための外ガード７と内ガード８、その間に設けた受け部９からなるカップ口部の受け部を構成し設けて有した、この支持辺６は箱形を構成したときの前後側の各側壁面をも構成している。
（７）さらに支持柱１１はシート材料１で構成した袋部２５を下から支える箱型の底部を構成し、支持辺６やその側辺５で各箱型の側壁面を構成する支持辺６や側辺５を支え保持してカップ口部をとらえながら箱形を形成保持するものである。
（８）支持柱１１は左折り目１９と右折り目２１の間に細長い形状で巾を狭く構えることでその両サイドに折り曲げ線１３を各設けて、両サイド方向に長く伸びた折り下げ辺１２が構成できる様にしており、又折り下げ辺１２の巾は、左折り目１９と右折り目２１の巾であり箱型全体の巾を有し両サイド方向にも長く伸び出て構成した大きな折り下げ辺１２であり、この折り下げ辺１２を下方に折り下げたとき、袋部２５の底部側の中央部だけをとらえる支持柱１１であるため袋部２５の底部側の左右の角部１５は下方に下がり折り下げ辺１２の外側の位置でポケット部１６を構成する。
（９）支持柱１１は中央部にある二つ折り部線１８を伸ばし平たく形成保持する両サイドの各折り下げ辺１２が左折り目１９と右折り目２１の巾を有した両サイドの折り下げ辺１２が折り曲げ線１３から下方に折り下がった状態では支持柱１１と両サイド側の折り下げ辺１２の両辺で下方向きのコの字型の箱状の形状になることで支持柱１１が前後の端部でカップ口部をとらえている支持辺６側の間で支持柱１１はカップ１７の口部の高さの位置で袋部２５を支えながら、その重量を支える高い支持力をも構成している。
（１０）このときに、この折り下げ辺１２は折り曲げられたため元に戻ろうとする復元力の働きが作用し垂直、下方より多少ポケット部１６側に向いている状態のため支持柱１１の上面に大きな下方向の力が加わると基本的に折り下げ辺１２は垂直下方向のどちらか向いた方向に曲がって行くが折り下げ辺１２は折り曲げ線１３から折り曲げられたポケット部１６側に戻ろうとする反発力で常にポケット部１６側を向いた状態のため内側方向ではなくポケット部方向に戻ろうとするが、これを止めるため袋部２５の底部側の両端の角部１５が各折り下げ辺１２の外側に下がり位置している、このポケット部１６内にコーヒー粉やお湯が入る事で大きな抑止力となり折り下げ辺１２が元に戻ろうとする作用をポケット部１６内の重量で押さえる又、長く伸び出た折り下げ辺１２であるため、てこの原理でポケット部１６は容易に折り下げ辺１２を押さえることができ折り下げ辺１２は下方向に折り下げられた状態で固定され完全に戻らなくなる。
（１１）支持体１１の両サイドに設けた各折り下げ辺１２は、折り曲げ線１３から支持柱１１側に伸び出て構成した押し上げ凸部１４を各それぞれ設け有しており、これは袋部２５の底部を浮かし支持体１１との間に一定の透き間を部分的に構成し袋部２５からの湯の流下をスムーズにする作用がある。
（１２）シート材料１には上方口２４を構成するためのミシン目４を上部側の端部３の内側の位置で左右巾に貫通したミシン目４を設けている。
（１３）このシート材料１と支持体２で構成した包材を二つ折り部線１８から全体を折り曲げ各端部３の三辺どうしを合わせ中にコーヒー粉等を充墳して三辺の端部３を封じて製袋形を構成している。Hereinafter, embodiments of the present invention will be described.
(1) A sheet material 1 having breathability and filterability is provided with a support body 2 which is made by waterproofing a cardboard or the like in advance, and an edge portion 3 is provided around the sheet material 1 at each sticking portion 22. The support 2 is attached to 1 and attached integrally.
(2) A half-folded part line 18 for folding the sheet material 1 to which the support body 2 is attached in half is provided in the center of the support body 2 so as to penetrate left and right.
(3) This support 2 is provided with a support column 11 forming a bottom surface for forming a box shape, which supports the bottom of the bag portion 25 from below when the bag portion 25 is formed by the sheet material 1. The support column 11 is to be held and which is located on the lower surface of the bottom portion of the bag portion 25 and supports the center portion of the bottom portion in the front and rear in an elongated shape with a narrow width.
(4) The support pillar 11 is slender in the vertical direction and has a narrow width to form a large space on the left and right sides, and the spaces provided on both sides of the support pillar 11 are provided in the both side directions via the bending lines 13. A large folding side 12 having the width of each long fold line 19 and right fold line 21 is formed so as to be provided, and further, an end of the support column 11 on the front side which is elongated in the front-rear direction. A left fold line 19 and a right fold line 21 are provided at the rear end of the portion, and support sides 6 forming side walls on the front and rear sides extend from the fold lines.
(5) Sides 5 are provided on the left and right of the upper side of the support side 6 via end folds 20, and the side 5 extends further downward from the upper opening 24 of the bag portion 25 to the bottom side. The bag portion 25 and the support body 2 extend to the left and right side walls when forming a box shape.
(6) Further, on both sides of the support side 6, there are respectively provided support arms 10 extending to the left and right, and at the lower end portions thereof, an outer guard 7 and an inner guard for receiving and receiving the mouth portion of the cup. 8 and the supporting portion 6 which constitutes and has the receiving portion of the cup mouth portion including the receiving portion 9 provided therebetween, the supporting side 6 also constitutes each of the front and rear side wall surfaces when forming a box shape.
(7) Further, the support pillars 11 form a box-shaped bottom portion that supports the bag portion 25 formed of the sheet material 1 from below, and the support sides 6 and the side edges 5 thereof constitute the side wall surfaces of each box-shaped support side 6. The side edge 5 is supported and held to form a box shape while holding the cup opening.
(8) The supporting pillar 11 has an elongated shape and a narrow width between the left fold line 19 and the right fold line 21 so that folding lines 13 are provided on both sides of the fold line 12 so that the folding side 12 extending long in both side directions is provided. The width of the folding side 12 is the width of the left fold line 19 and the right fold line 21 and has the width of the entire box shape, and is a large folding side formed by extending long in both side directions. When the folding side 12 is folded downward, the support column 11 catches only the central portion on the bottom side of the bag portion 25, so that the left and right corners 15 on the bottom side of the bag portion 25 are lowered. The pocket portion 16 is formed at a position outside the downward folding side 12.
(9) The support pillar 11 extends and folds the double-folded line 18 at the center, and holds each folded side 12 on both sides having the width of the left fold 19 and the right fold 21. In a state in which the support pillar 11 is folded downward from the fold line 13, the support pillar 11 and the folding sides 12 on both sides have a U-shaped box shape that faces downwards. While supporting the bag portion 25 at the height level of the mouth portion of the cup 17 between the support sides 6 side which catches the cup mouth portion with the cup portion, the support pillar 11 also has a high supporting force for supporting the weight thereof. There is.
(10) At this time, since the folding down side 12 is bent, the restoring force that tries to return to the original side acts, and the folding side 12 is vertical and slightly toward the pocket portion 16 side from below. When a large downward force is applied, the folding side 12 basically bends in either vertical downward direction, but the folding side 12 tries to return from the folding line 13 to the side of the folded pocket portion 16. Since the repulsive force always faces the pocket portion 16 side, it tries to return to the pocket portion direction instead of the inward direction, but in order to stop this, the corner portions 15 at both ends on the bottom side of the bag portion 25 have the folding sides 12 of the respective folding sides 12. When coffee powder or hot water enters the pocket 16 which is located at the outer side, it becomes a great deterrent and the folding side 12 tries to return to its original position. Since it is the protruding side 12, the pocket portion 16 can easily press the folded side 12 by the lever principle, and the folded side 12 is fixed in the state of being folded downward and cannot be completely returned.
(11) Each of the folding sides 12 provided on both sides of the support body 11 has a pushing-up convex portion 14 formed by extending from the bending line 13 to the support column 11 side, which is a bag portion.
