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 drip-type extraction bag for regular coffee or the like that is placed and set on a drinking container, and is a filter bag made of a sheet material having water permeability and a filterable property and having an opening at the top. A support made of a member such as thick paper that has been waterproofed is attached to this filter bag, and the filter bag is supported and placed on the mouth of a drinking container such as a cup. It is related to the drip extraction bag used by pouring hot water into the coffee powder in this bag and extracting and dripping it.

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 and place it in place, the support attached to the filter bag is a flexible filter bag with a rigid support and a cup mouth support on the cup mouth. However, the bag is held on the mouth of the cup while forming the bag shape of the bag, but the type of extraction bag that can use this support a lot has the filter bag placed high on the cup. The extraction bag, which is a bag-making method, has a high drip property without touching the hot water surface in the cup, but on the other hand, a support is attached to the filter sheet in advance and attached, and this sheet-shaped filter bag is folded in half. Then, the ends of the three sides other than the creases are sealed, and coffee powder is filled inside. Since this bag making method has a process of sealing the three sides, the ends of the three sides are pasted together. Since it is necessary to secure a space for the bag and the size of the support is limited only within the range inside this space, a large support area cannot be used, and a high filtration bag is placed on the cup mouth. It is not possible to improve the floating drip property, and there is a tendency to use a hanging method in which the mouth of the cup is caught and the filter bag is positioned inside the cup. Although there were many problems and restrictions such as being unsuitable for use, the bag-making method type has a product cost of about 1/10 compared to the type in which the support can extend outward more than the filter bag type. In terms of it, there was a big advantage.

特許第２５０５９５９号Patent No. 2505959 特開平１１－１７８７２０Japanese Patent Application Laid-Open No. 11-178720 特許第３７２７２７０号Patent No. 3727270 特開２００４－１３０１０４JP-A-2004-130104 特開２００９－９６５０７JP 2009-96507 特願２０１８－２１７７４５Japanese Patent Application No. 2018-217745 特願２０１８－２３６７８４Japanese Patent Application No. 2018-236784

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。
（二）特願２０１８－２１７７４５や特願２０１８－２３６７８４に示す様に、支持体２で構成する箱状形の中に位置する袋部２５を下から支える支持柱１１が右折り目２１と左折り目１９の前後の方向に長く左右方向に中の狭い形状で構えており、その左右両側に各、折り曲げ線１３から伸びた折り下げ辺１２を有しており、これが支持体２が箱形を形成した時には、下方に折れ下がり同時に袋部２５の角部１５も下がりポケット部１６を形成するが、支持柱１１が細長く構える事で両側の各、折り下げ辺１２を大型としているためにポケット部１６も大型となり、お湯を注いだ時の重量が大きくなり下方に下がろうとするポケット部１６の力で支持体２の箱形全体が変形しやすい問題が生じた。It had the following problems.
(B) In the type (Japanese Patent Laid-Open No. 2004-130104) and (Japanese Patent Laid-Open No. 2009-96507) in which the filter bag is located on the cup, the position of the bag is high, and the lower part of the bag does not soak in the hot water in the cup, and the drip property is achieved. Although it is good, it will be a large coffee bag as a whole, and the production equipment will be large, so the cost will be high.
(B) Compared to that, in the case of the bag making method such as (Patent No. 2505959), (Japanese Patent Laid-Open No. 11-178720) and (Patent No. 3727270), the production equipment is about 1/10, which is a low cost advantage. However, as a feature of the bag making method, the sheet material with the support attached in advance is folded in half and combined with the sheet material having filterability. Since it is a method of filling coffee powder, it is a support of a size within the inner range that leaves space at the end of the three sides to be sealed around the sheet material, so this limited area and size It was difficult to improve the drip property by constructing a structure that holds the filter bag high on the cup so that the bag part is not soaked in the hot water in the cup by forming the whole shape three-dimensionally with the support of. ..
(C) Further, (Patent No. 3727270) extends the folds of the support to form a trapezoidal shape on the cup, and (Japanese Patent Laid-Open No. 2004-130104) and (Japanese Patent Laid-Open No. 2009-96507) form a boat shape with the support. The mouth of the bag is opened and held on each cup, but in (Patent No. 3727270), the fold of the support is extended and fixed at the folded side in order to extend and fix the crease of the support, but it is folded back. In the method, the folded side may return to the original position, and (Japanese Patent Laid-Open No. 2004-130104) and (Japanese Patent Laid-Open No. 2009-96507) are triangular and have a small folding portion to open and fix the support in a boat 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, the bending force cannot be fixed as it is in the folded direction.
(2) As shown in Japanese Patent Application No. 2018-217745 and Japanese Patent Application No. 2018-236784, the support pillar 11 that supports the bag portion 25 located in the box shape formed by the support 2 from below has a right fold 21 and a left fold. It is long in the front-back direction of 19 and has a narrow shape in the left-right direction, and each has a folding side 12 extending from the bending line 13 on both the left and right sides thereof, and the support 2 forms a box shape. At the same time, the corner portion 15 of the bag portion 25 also lowers to form the pocket portion 16, but the pocket portion 16 is formed because the support pillar 11 is held long and slender and the folded sides 12 on both sides are large. Also became large, and the weight when hot water was poured became large, and there was a problem that the entire box shape of the support 2 was easily deformed by the force of the pocket portion 16 trying to lower.

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の中央部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部として中央部に支持柱１１を設け、シート材料１で構成する袋部２５の底部側の左右の角部１５をそれぞれ左右の側方に位置させ底部の中央部に、支持柱１１を前後方向に構えて袋部２５の底部を下から支え位置しており、箱型の前後の側壁は、前後方向に構えた支持柱１１の前部側の端に設けた左折り目１９を介し支持辺６を伸び出て設け有し、後部側の端には右折り目２１を介し支持辺６が同じく伸び出て設け有している、この各、支持辺６は下部側は左右両方向に伸び出た支持アーム１０を有し設け広巾であり、その下端部には外ガード７と内ガード８の間に設けた受け部９を設けており、さらにこの各、支持辺６の上部側の左右端部には折り目２０から各、左右側に、それぞれ伸び出て、箱型の左右側壁となる側辺５が設けられ有している、さらに支持柱１１は、左折り目１９と右折り目２１の間の巾で両側に設けた各、折り曲げ線１３から両側方向に伸び出た折り下げ辺１２を各、有し設けている、このシート材料１と支持体２で構成した全体を、二つ折り部線１８から折り曲げ、シート材料１の他の３辺の端部３どうしを合わせ一体に封じて、シート材料１により袋部２５を構成しており、袋部２５の上方口２４は上方側の端部３の下側に左右方向にミシン目４を設けている。In the present invention, a support 2 formed by preliminarily waterproofing thick paper or the like on a sheet material 1 having water permeability and filterability is provided with an end portion 3 around the sheet material 1 and a sticking portion 22 is provided. A double-folded portion line 18 for folding the entire sheet material 1 in half, which is attached to the sheet material 1 by attaching the support 2 to the sheet material 1 in half, is provided through the center of the support 2 to the left and right. The support 2 is provided with a support pillar 11 in the center as a bottom portion constituting the box shape, and the left and right corner portions 15 on the bottom side of the bag portion 25 composed of the sheet material 1 are positioned on the left and right sides, respectively.

The support side 6 is provided so as to extend through the left crease 19 provided in the above, and the support side 6 is also provided so as to extend through the right crease 21 at the rear end. The lower side has a support arm 10 extending in both the left and right directions and is wide, and a receiving portion 9 provided between the outer guard 7 and the inner guard 8 is provided at the lower end thereof. The left and right ends on the upper side of the support side 6 are provided with side sides 5 extending from the crease 20 on the left and right sides to form box-shaped left and right side walls. Further, the support pillar 11 has a support pillar 11. The sheet material 1 and the support 2 are provided with each of the width between the left crease 19 and the right crease 21 provided on both sides, and each of the folded sides 12 extending in both sides from the folding line 13. The entire configuration is bent from the bi-folded portion line 18, the other three side ends 3 of the sheet material 1 are aligned and sealed integrally, and the bag portion 25 is composed of the sheet material 1 to form the bag portion 25. The upper opening 24 is provided with a perforation 4 in the left-right direction on the lower side of the upper end portion 3.

側辺５は、袋部２５の上方口４側から下方に伸びて側壁を構成し、さらに袋部２５の左右下端の角部１５まで伸びて達した細長部３０を有し設けている。The side side 5 is provided with an elongated portion 30 extending downward from the upper opening 4 side of the bag portion 25 to form a side wall, and further extending to the corner portions 15 at the lower left and right ends of the bag portion 25.

支持柱１１の両サイドの折り曲げ線１３から各、伸び出た折り下げ辺１２は折り曲げ線１３から支持柱１１の支持面３７側に伸び出て構成した押し上げ凸部１４を有している。Each of the folded-down sides 12 extending from the bending lines 13 on both sides of the support pillar 11 has a push-up convex portion 14 extending from the bending line 13 to the support surface 37 side of the support pillar 11.

支持体２が箱形を形成したとき、底部を構成する支持柱１１の両サイド側に位置する袋部２５の左右の角部１５が、支持柱１１の両サイド側で下方に折り下がり構成している折り下げ辺１２の外側の側方に位置して下方に向いたポケット部１６を構成している。When the support 2 forms a box shape, the left and right corners 15 of the bag portion 25 located on both side sides of the support pillar 11 constituting the bottom portion are configured to be folded downward on both side sides of the support pillar 11. The pocket portion 16 is located on the outer side of the folded-down side 12 and faces downward.

支持柱１１の両サイドに有する折り曲げ線１３から伸び出た折り下げ辺１２は、固定部２９から曲がり部２８と伸び、先端を押え辺２６で構成した折り下げ辺１２であり、曲がり部２８から切断線２７で先端方向に中央部で左右に分離している折り下げ辺１２である。The folding side 12 extending from the bending line 13 on both sides of the support pillar 11 is a folding side 12 extending from the fixed portion 29 to the bending portion 28 and having the tip formed of the holding side 26, and is a folding side 12 extending from the bending portion 28. It is a folded side 12 separated to the left and right at the central portion in the tip direction by the cutting line 27.

支持柱１１の支持面３７に穴部３１を設けている。A hole 31 is provided in the support surface 37 of the support pillar 11.

支持柱１１の両サイドの折り曲げ線１３から各、伸び出て設けた折り下げ辺１２に於いて、先端側の押さえ辺２６から固定部２９に向け伸びた切断線２７は、曲がり部２８からＵ字部３２を構成し、二つ折り部線１８の両サイド側に伸びて先端部３３が固定部２９に達してＵ字部３２構成している切断線３４である。In the folding side 12 extending from the bending lines 13 on both sides of the support pillar 11, the cutting line 27 extending from the holding side 26 on the tip side toward the fixed portion 29 is U from the bending portion 28. It is a cutting line 34 that constitutes a character portion 32, extends to both sides of the bi-fold portion line 18, and the tip portion 33 reaches the fixed portion 29 to form a U-shaped portion 32.

支持柱１１は袋部２５の底部の下面側に位置して、左折り目１９と右折り目２１の間を前後方向の巾とし、左右方向の巾は両サイドの折り曲げ線１３の間を両サイド方向の巾としており、この両サイド方向の巾を広巾の支持柱１１として、大きな支持面３７を構成しており、さらに、その両サイドの折り曲げ線１３から外方向に伸び出た折り下げ辺１２の長さを小さくした形状の折り下げ辺１２としている。The support pillar 11 is located on the lower surface side of the bottom of the bag portion 25, and the width in the front-rear direction is between the left crease 19 and the right crease 21, and the width in the left-right direction is the width between the bending lines 13 on both sides in both sides. The width in both side directions is used as the wide support pillar 11 to form a large support surface 37, and the folding side 12 extending outward from the bending lines 13 on both sides thereof. The folded side 12 has a shape with a reduced length.

（Ａ）箱形を形成した支持体２の底部を構成する支持柱１１の前後に各設けた支持辺６の下端部の左右に設けた受け部９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の両辺は、二つ折り部線１８の折り目を伸ばしながら支持柱１１との三辺で、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は、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巾であり又、さらに支持柱１１が前後に構えている両サイド側に位置し構えているため折り下げ辺１２となり二つ折り部線１８を伸ばし固定する作用が構成される。
（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を下方に下がって位置し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でポケット部１６を構成させ支持柱１１の両サイド側の折り下げ辺１２の外側に位置させ設けることができる。
（Ｆ）支持体２の前後の支持辺６の上部側から左右に伸びて構成する側辺５で箱形の側壁を形成したとき、側辺５の下方に伸びる細長部３０が角部１５まで伸びてポケット部１６の外側に位置して設けており、ポケット部１６とその内側に位置する折り下げ辺１２も一緒に下方に細長部３０は押し下げポケット部１６も構成させながら折り下げ辺１２も下方に押し下げ固定することができ支持辺６を前後方向に開くだけで箱形状となりカップへのセット状態になる。
（Ｇ）箱型を形成したとき、側辺５の下方の細長部３０が角部１５を外側から押し下げ、ポケット部１６を下方向きにさせたときポケット部１６内のコーヒー粉や、お湯の重量でさらにポケット部１６が下方向きに位置し安定した状態になり、この時ポケット部１６の重量と細長部３０の作用とで下方に向き位置している折り下げ辺１２が外側からポケット部１６に押えられて支持柱１１の二つ折り部線１８を平面形に固定化していることで、側辺５や支持辺６の側壁も同時に固定されて、箱形状を固定化した状態に保てる。
（Ｈ）折り下げ辺１２の先端側の、押え辺２６と曲がり部２８側が、切断線２７により先端方向に向け左右に分離していることと、曲がり部２８の柔軟性とで、左右の押え辺２６が左右に分離して、それぞれポケット部１６をとらえながら自在に、折り下げ辺１２が動き柔軟に折り下がれる様になるため、折り下げ辺１２が、折れ下がる時の箱部に生じる衝撃を分散して衝撃を和らげる事ができ、又このとき生じる細長部３０の折れ曲がりも和らげて防げる。
（Ｉ）支持柱１１の支持面３７の形状が前後の左折り目１９と右折り目２１の間の巾と両サイドに設けた折り下げ辺１２の間の巾と同等程度として上方口２４と同じ正四角形に近い形状となり支持面３７の面積が拡大した分袋部２５内の重量の多くを支持面３７が支え両サイドの巾が拡大した分の両サイドに設けた折り下げ辺１２の両サイド方向の長さが小さくなりその分の袋部２５の下部両端側の角部１５が下方に下がり構成するポケット部１６が小さくなり、お湯の入る量が少ない分ポケット部１６の重量が小さくなりポケット部１６の重量で下方に下がろうとする力が小さくなり箱形を形成保持する支持体２の箱形状がお湯を注いだ時のポケット部１６内の重量で生じさせる変形を小さくできる。(A) The mouth portion of the cup 17 is captured by the receiving portions 9 provided on the left and right of the lower end portions of the support sides 6 provided before and after the support pillar 11 constituting the bottom portion of the support body 2 having a box shape. Therefore, since the support pillar 11 is located at the height of the mouth portion 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 hot water surface in the cup 17.
(B) Both sides of the folded sides 12 on both sides of the support pillar 11 are three sides with the support pillar 11 while extending the crease of the bi-folded portion line 18, and have a downward U-shaped box shape. Since it is formed, the support pillar 11 can form a high strength that supports the weight of the bag portion 25.
(C) The folded sides 12 on both sides for extending the central bi-folded portion line 18 of the support pillar 2 and keeping the support pillar 11 flat are the width between the left fold 19 and the right crease 21 of the support pillar 11. The width is configured, and since the support pillars 11 are located on both sides of the front and rear, the folded sides 12 are formed, and the function of extending and fixing the bi-folded portion line 18 is configured.
(D) When a box shape is formed by the support 2, the pocket portion 16 is located and provided on the outside of the folded-down side 12 which is folded downward, and is provided in the pocket portion 16. When coffee powder or hot water enters, the folded side 12 cannot be restored after being folded and can be fixed.
(E) Since the support pillar 11 supports only the central portion of the bottom of the bag portion 25 from below, the pocket portion 16 is formed by the left and right corner portions 15 on the bottom side of the bag portion 25, and the support pillar 11 is folded down on both sides. It can be provided so as to be located on the outside of the side 12.
(F) When a box-shaped side wall is formed by the side side 5 extending from the upper side of the front and rear support sides 6 of the support body 2 to the left and right, the elongated portion 30 extending below the side side 5 extends to the corner portion 15. It is extended and provided so as to be located on the outside of the pocket portion 16, and the pocket portion 16 and the folding side 12 located inside the pocket portion 16 are also provided downward. It can be pushed down and fixed, and just by opening the support side 6 in the front-back direction, it becomes a box shape and is set in the cup.
(G) When the box shape is formed, when the elongated portion 30 below the side side 5 pushes down the corner portion 15 from the outside and the pocket portion 16 faces downward, the weight of the coffee powder and hot water in the pocket portion 16 Further, the pocket portion 16 is positioned downward and becomes a stable state. At this time, the folded side 12 that is positioned downward due to the weight of the pocket portion 16 and the action of the elongated portion 30 is moved from the outside to the pocket portion 16. By being pressed and fixing the bi-folded portion line 18 of the support column 11 in a planar shape, the side walls 5 and the side walls of the support side 6 are also fixed at the same time, and the box shape can be kept fixed.
(H) The left and right pressers due to the fact that the presser side 26 and the bent portion 28 side on the tip side of the folded side 12 are separated left and right toward the tip direction by the cutting line 27 and the flexibility of the bent portion 28. Since the sides 26 are separated to the left and right so that the folded side 12 can move freely while grasping the pocket portion 16 and can be flexibly folded down, the folded side 12 is generated in the box portion when the side is folded down. The impact can be dispersed and the impact can be softened, and the bending of the elongated portion 30 that occurs at this time can also be softened and prevented.
(I) The shape of the support surface 37 of the support pillar 11 is the same as that of the upper opening 24 so that the width between the front and rear left creases 19 and the right crease 21 and the width between the folded sides 12 provided on both sides are about the same. The shape close to a square and the area of the support surface 37 is expanded. Most of the weight in the bag portion 25 is supported by the support surface 37, and the width of both sides is expanded. The length of the pocket portion 25 becomes smaller, the corners 15 on both ends of the lower end of the bag portion 25 are lowered downward, and the pocket portion 16 constituting the pocket portion 16 becomes smaller. With the weight of 16, the downward force is reduced, and the box shape of the support 2 that forms and holds the box shape can reduce the deformation caused by the weight in the pocket portion 16 when hot water is poured.

（４）この支持柱１１は前後方向に構えた左右の両サイド方向には支持柱１１の左右に設けた折り曲げ線１３を介しそれぞれ両サイド方向に各、伸び出させた折り下げ辺１２を設け、これは左折り目１９と右折り目２１の間を有する広巾で、大型の折り下げ辺１２を構成させて各、左右に設け有しており、さらに支持柱１１の、この前後方向の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を有したこの各折り目から、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、それぞれ伸び出て側辺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り、さらに、この側辺５は下方の角部１５まで伸びた細長部３０を設け有しており袋部２５の角部１５が構成するポケット部１６の外側に構えシート材料１に一体に細長部３０は貼着されて設け有している。
（６）さらに、この支持辺６の下部側の両側部には左右に伸び出た支持アーム１０を、それぞれ有し、広巾となり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ている。
（７）さらに支持柱１１は、左右に有した折り曲げ線１３から左右下方に折り下げた折り下げ辺１２により、二つ折り部線１８を平たく伸ばし支持柱１１を平たく固定し、シート材料１で構成した袋部２５を下から支える、下方向きのコの字型の底部を構成し、上方向きの支持辺６やその側辺５で箱型の側壁面を構成し、これを支え保持してカップ口部をとらえながら箱形をカップ口部上に袋部２５を形成保持するものである。
（８）支持柱１１は前後方向に、構えることでその両サイドに折り曲げ線１３を各設けて、両サイド方向に伸びた折り下げ辺１２が構成できる様にしており、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の外側の位置で袋部２５の底部の左右の角部１５が下方に下がりポケット部１６を構成できる様にしている。
（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であり、折り曲げ線１３から下方に折り下がった状態で支持柱１１と両サイド側の折り下げ辺１２との両辺で下方向きのコの字型の箱状の形状を構成していることで支持柱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は袋部２５の底部をカップ１７の口部の高さの位置で支えながら、その重量を支える高い支持力を下方向きのコの字形の箱形状で構成させている。
（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、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ポケット部１６を構成している、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とともに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側の押え辺２６を、とらえ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）支持柱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側の面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柱１１とシート材料１との間に一定の透き間を部分的に構成し袋部２５からのお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。
（１４）支持体２で、この箱形を形成するとき、図７に示す様に、一時的に支持柱１１と両サイドの折り下げ辺１２が全体に平たい状態になる過程を経て、初めて折り曲げ線１３から左右の各、折り下げ辺１２が下方に折り下がることが出来る為、側辺５の下方に伸びて設けた、折り下げ辺１２を下方に押し下げる為の細長部３０がポケット部１６の外側に位置してポケット部１６と一緒に折り下げ辺１２を下方に折し下げたとき、支持柱１１と同じ水平の平たい状態から一気に左右の折り下げ辺１２が折り下がる為め一定の振動が支持柱１１に生じ中のコーヒー粉が上方口２４から多少、飛散することがあり、これを防ぐ為め、折り下げ辺１２が支持柱１１の、折り曲げ線１３から伸び出て構成するとき、二つ折り部線１８を伸ばし固定するのに必要な最小限の折り下げ辺１２の作用を固定部２９で作用を確保し、中間部の曲がり部２８から先端部側の押え辺２６が切断線２７で左右に分離した構成の折り下げ辺１２とすることで、側辺５の細長部３０によりポケット部１６と一緒に押し下げられた折り下げ辺１２の曲がり部２８から押え辺２６側に左右に開き折れ曲がり自在にポケット部１５を受け止め一気に折り下がらず徐徐に、柔軟に折り下がる様にしており、又押し下げようとする細長部３０が折れて機能しなくなることも防ぎ、又折り下げ辺１２が曲がり部２８と先端部の押え辺２６とで構成した折り下げ辺１２であることで容易に細長部３０が、てこ、の原理で押し下げれる様にしている。
（１５）支持柱１１に設けた穴部３１は支持柱１１面に溜ったコーヒー液を流下させるもので、押し上げ凸部１４も支持柱１１側に穴部を構成するため同じ作用がある。
（１６）支持柱１１の両サイドに設けた折り下げ辺１２は、折り曲げ線１３から、各伸び出て、固定部２９を形成し中間部を曲がり部２８として、その先端側に押え辺２６を有し構成しており、この固定部２９から伸びでて、曲がり部２８と押え辺２６の部分が左右に分離して左右が自在に動く為に左右の根元側の固定部２９の中央に位置する二つ折り部線１８の折り目の部分に左右、上下に引っ張られる作用が集中するため、この折り目からの亀裂や切断が生じると、支持柱１１を折り下げ辺１２で平たく保てなくなるため、これを防ぐため、図８に示す様に、二つ折り部線１８の部分だけを固定部２９の巾を大きくして強度を高めており又、折り下げ辺１２の先端側の押え辺２６から曲がり部２８に伸びる切断線３４の先端部３３が左右に分離して二つ折り部線１８の両サイド側に伸びＵ字部３２を構成し固定部２９に達する様にして、二つ折り部線１８の折り目に集中して力が作用しない様にしており、左右に分離した折り下げ辺１２の左辺３５と右辺３６が自在に、それぞれ動く力を二つ折り部線１８の折り目部に達し集中しない様にしている。
（１７）支持柱１１は袋部２５の底部の下面側に位置して、左折り目１９と右折り目２１の間を前後方向の巾とし、左右方向の巾は両サイドの折り曲げ線１３の間を両サイド方向の巾としており、この両サイド方向の巾を広巾の支持柱１１として、大きな支持面３７を構成しており、さらに、その両サイドの折り曲げ線１３から外方向に伸び出た折り下げ辺１２の長さを小さくした形状の折り下げ辺１２としている。
（１８）支持柱１１の支持面３７の形状が前後の左折り目１９と右折り目２１の間の巾と両サイドに設けた折り下げ辺１２の間の巾と同等程度として上方口２４と同じ正四角形に近い形状となり支持面３７の面積が拡大した分袋部２５内の重量の多くを支持面３７が支え両サイドの巾が拡大した分の両サイドに設けた折り下げ辺１２の両サイド方向の長さが小さくなりその分の袋部２５の下部両端側の角部１５が下方に下がり構成するポケット部１６が小さくなり、お湯の入る量が少ない分ポケット部１６の重量が小さくなりポケット部１６の重量で下方に下がろうとする力が小さくなり箱形を形成保持する支持体２の箱形状がお湯を注いだ時のポケット部１６内の重量で生じさせる変形を小さくできる。Hereinafter, embodiments of the present invention will be described.
(1) A support 2 formed by preliminarily waterproofing thick paper or the like on a sheet material 1 having a breathable filter property is provided with an end portion 3 around the sheet material 1 and a sheet is provided at each of the pasting portions 22. The support 2 is attached to the material 1 and attached integrally.
(2) A bi-fold portion line 18 for folding the sheet material 1 to which the support 2 is attached in half is provided in the center of the support 2 so as to penetrate in the left-right direction.
(3) The support 2 is provided with a support pillar 11 forming a bottom surface for forming a box shape, and when the sheet material 1 is folded in half to form a bag portion 25, the support 2 is formed. It is located on the outer surface side of the bag 25 and supports and holds the bottom of the bag 25 from below. It is located on the lower surface of the bottom of the bag 25, holds the center of the bottom in the front-rear direction, and supports the bag 25. It is a support pillar 11.
(4) The support pillar 11 is provided with folded sides 12 extending in both side directions via bending lines 13 provided on the left and right sides of the support pillar 11 in the left and right side directions held in the front-rear direction. , This is a wide width having a space between the left crease 19 and the right crease 21, and is provided on each side by forming a large folding side 12, and further, the front side of the support pillar 11 in the front-rear direction. The left crease 19 is provided at the end of the fold, and the right crease 21 is provided at the rear end.
(5) Side sides 5 are provided on the left and right sides of the upper side of the support side 6 via end creases 20, and the side sides 5 extend further downward to the upper opening 24 of the bag portion 25. The bag portion 25 and the support 2 form a side wall on the left and right sides when the bag portion 25 and the support 2 form a box shape, and the side side 5 is an elongated portion extending to the lower corner portion 15. 30 is provided and is provided on the outside of the pocket portion 16 formed by the corner portion 15 of the bag portion 25, and the elongated portion 30 is integrally attached to the sheet material 1.
(6) Further, each of the support arms 10 extending to the left and right is provided on both sides of the lower side of the support side 6, and the width is wide, and the lower end thereof is an outer guard for catching the mouth of the cup. A receiving portion of a cup mouth portion including a receiving portion 9 provided between the 7 and the inner guard 8 is configured and provided.
(7) Further, the support pillar 11 is composed of the sheet material 1 by extending the bi-folded portion line 18 flatly and fixing the support pillar 11 flatly by the folding side 12 folded downward from the folding lines 13 held on the left and right. A downward U-shaped bottom that supports the bag portion 25 from below is formed, and a box-shaped side wall surface is formed by the upward support side 6 and its side side 5, and the cup is supported and held. The bag portion 25 is formed and held on the cup mouth portion in a box shape while grasping the mouth portion.
(8) The support pillar 11 is provided with bending lines 13 on both sides of the support pillar 11 by holding the support pillar 11 in the front-rear direction so that a folding side 12 extending in both side directions can be formed. Since the support pillar 11 captures only the central portion on the bottom side of the bag portion 25 when folded downward, the left and right corner portions 15 on the bottom side of the bag portion 25 are lowered downward, and the position outside the folded side 12 The left and right corners 15 of the bottom of the bag portion 25 are lowered downward so that the pocket portion 16 can be formed.
(9) The support pillar 11 is formed and held flat by extending the bi-folded portion line 18 in the central portion. It is supported by forming a downward U-shaped box shape on both sides of the support pillar 11 and the folded sides 12 on both sides in a state of being folded downward from the bending line 13. The support pillar 11 supports the weight of the support pillar 11 while supporting the bottom of the bag portion 25 at the height of the mouth portion of the cup 17 between the support side 6 sides where the pillar 11 catches the cup mouth portion at the front and rear ends. The high bearing capacity is composed of a downward U-shaped box shape.
(10) At this time, since the folded side 12 is bent, the action of the restoring force that tries to return to the original action acts, and the folded side 12 is vertically oriented toward the pocket portion 16 side from the lower side, so that it is on the upper surface of the support column 11. When a large downward force is applied, the folded side 12 basically bends in either the vertical downward direction, but the folded side 12 tries to return from the bending line 13 to the bent pocket portion 16. Since the repulsive force always faces the pocket portion 16, the corner portions 15 at both ends on the bottom side of the bag portion 25 are positioned to descend to the outside of each folded side 12 to form the pocket portion 16. When coffee powder or hot water enters the pocket portion 16, it becomes a great deterrent, and the action of the folded side 12 trying to return to its original state is suppressed by the weight inside the pocket portion 16 and the extended folded side 12 is used. Therefore, the pocket portion 16 can easily catch and hold the holding side 26 on the folded side 12 side by the principle of the lever, and the folded side 12 is fixed in a state of being folded downward and cannot be completely returned. ..
(11) Each folding side 12 provided on both sides of the support pillar 11 has a push-up convex portion 14 extending from the bending line 13 to the surface on the support pillar 11 side, respectively. The bottom of the bag portion 25 is floated to partially form a certain gap between the support pillar 11 and the sheet material 1, which has the effect of smoothing the flow of hot water from the bag portion 25.
(12) The sheet material 1 is provided with a perforation 4 for forming the upper opening 24, which penetrates the left and right widths at a position inside the upper end portion 3.
(13) The packaging material composed of the sheet material 1 and the support 2 is folded in half from the bi-folded part line 18 and the whole is bent. The part 3 is sealed to form a bag-making shape.
(14) When the support 2 forms this box shape, as shown in FIG. 7, it is bent for the first time after the support pillar 11 and the folded sides 12 on both sides are temporarily flattened as a whole. Since each of the left and right folded sides 12 can be folded downward from the line 13, the elongated portion 30 provided extending below the side side 5 for pushing down the folded side 12 is the pocket portion 16. When the folded side 12 is folded downward together with the pocket portion 16 located on the outside, constant vibration is generated because the left and right folded sides 12 are folded down at once from the same horizontal flat state as the support column 11. The coffee powder generated in the support pillar 11 may be slightly scattered from the upper opening 24, and in order to prevent this, when the folded side 12 is configured to extend from the bending line 13 of the support pillar 11, two. The minimum folding side 12 required to extend and fix the folded portion line 18 is secured by the fixing portion 29, and the holding side 26 on the tip side from the bending portion 28 in the middle portion is formed by the cutting line 27. By forming the folded side 12 separated into left and right, the folded side 12 is pushed down together with the pocket portion 16 by the elongated portion 30 of the side side 5, and is bent left and right from the bent portion 28 to the holding side 26 side. The pocket portion 15 is freely received and does not fold down at once, but is gradually and flexibly folded down. It also prevents the elongated portion 30 to be pushed down from breaking and not functioning, and the folded-down side 12 is a bent portion 28. Since the folded side 12 is composed of the holding side 26 at the tip portion, the elongated portion 30 can be easily pushed down by the principle of the lever.
(15) The hole portion 31 provided in the support pillar 11 allows the coffee liquid accumulated on the surface of the support pillar 11 to flow down, and the push-up convex portion 14 also has the same function because it forms a hole portion on the support pillar 11 side.
(16) The folded sides 12 provided on both sides of the support pillar 11 extend from the bent line 13 to form a fixed portion 29, the intermediate portion is used as a bent portion 28, and the holding side 26 is provided on the tip end side thereof. It is located in the center of the fixed part 29 on the left and right root side because it extends from this fixed part 29 and the bent part 28 and the holding side 26 are separated to the left and right and move freely to the left and right. Since the action of pulling left and right and up and down is concentrated on the crease portion of the bi-fold portion line 18, if cracks or cuts occur from this crease, the support column 11 cannot be kept flat on the folded side 12, so this As shown in FIG. 8, the width of the fixing portion 29 is increased only at the portion of the bi-folded portion line 18 to increase the strength, and the bent portion from the holding side 26 on the tip side of the folded side 12 is bent. The tip portion 33 of the cutting line 34 extending to 28 is separated to the left and right to form an extending U-shaped portion 32 on both sides of the bi-folded portion line 18 so as to reach the fixed portion 29, and the fold of the bi-folded portion line 18 is formed. The left side 35 and the right side 36 of the folded side 12 separated to the left and right freely reach the crease part of the bi-fold part line 18 so that the force does not concentrate on the fold. There is.
(17) The support pillar 11 is located on the lower surface side of the bottom of the bag portion 25, and the width in the front-rear direction is between the left crease 19 and the right crease 21, and the width in the left-right direction is between the bending lines 13 on both sides. The width in both sides is defined as the width in both sides, and the width in both sides is used as the wide support pillar 11 to form a large support surface 37, and further, the folding is extended outward from the bending lines 13 on both sides. The folded side 12 has a shape in which the length of the side 12 is reduced.
(18) The shape of the support surface 37 of the support pillar 11 is the same as that of the upper opening 24 so that the width between the front and rear left creases 19 and the right crease 21 and the width between the folded sides 12 provided on both sides are about the same. The shape close to a square and the area of the support surface 37 is expanded. Most of the weight in the bag portion 25 is supported by the support surface 37, and the width of both sides is expanded. The length of the pocket portion 25 becomes smaller, the corners 15 on both ends of the lower end of the bag portion 25 are lowered downward, and the pocket portion 16 constituting the pocket portion 16 becomes smaller. With the weight of 16, the downward force is reduced, and the box shape of the support 2 that forms and holds the box shape can reduce the deformation caused by the weight in the pocket portion 16 when hot water is poured.
