カップ上にセットして使用するコーヒーバッグの袋の口部形は円形に近いほどコーヒーの抽出にむらが少なく、又口部の中央にお湯を注ぎその位置から袋部のあらゆる方向のフィルター面までの距離が均等であることも抽出むらを小さくする、この袋をカップ上に位置して支持するための支持体構成によっては袋の口部形が三角型や舟型等など口部形上に於いて鋭角部が生じることや又大型になるケースなどでも抽出むらの一因となった。〔特開２００４−２４７６３〕 As the mouth shape of the bag of the coffee bag set on the cup is closer to a circle, there is less unevenness in coffee extraction, and hot water is poured into the center of the mouth from the position to the filter surface in all directions of the bag Even if the distance of the bag is uniform, the unevenness of the extraction is reduced, and depending on the structure of the support for positioning the bag on the cup, the mouth shape of the bag may be on the mouth shape such as a triangle shape or a boat shape. However, the occurrence of sharp corners and large cases also contributed to uneven extraction. [JP 2004-24763]

袋部をカップ上に浮かせ保持する支持体はカップ口径より大きい構成であり袋部はカップ口径より小さいため通常の上のせドリップタイプのコーヒーバッグの場合にこれらを生産する設備の工程は袋部を構成し袋内にコーヒー粉を充填し袋部より大きな支持体を構成したものを袋部と一体化する工程となり工程数の多い大型の生産設備となりコスト高となった。〔特開２０００−２７９３２３〕 The support body that floats and holds the bag portion on the cup is configured to be larger than the cup diameter, and the bag portion is smaller than the cup diameter. It was a process of filling the coffee powder in the bag and forming a support larger than the bag part and integrating it with the bag part, resulting in a large-scale production facility with many processes and high costs. [JP 2000-279323]

これに比較し通水濾過性を有した帯状のシートにあらかじめ袋部より小さい小型の支持体を取り付けて２枚折りにした中にコーヒー粉を充填しながら三辺をヒートシール等で熱融着させる充填生産設備では工程も少なく生産設備も簡略化できコスト的に有利であるが次の様な課題があった。 Compared to this, a small sheet support smaller than the bag part is attached to a band-shaped sheet that has a water-passing filterability in advance and folded into two sheets. The filling production facility to be used has few processes and the production facility can be simplified, which is advantageous in terms of cost, but has the following problems.

通水濾過性を有した帯状シートの三辺をヒートシール等により熱融着する製袋方式の充填設備で生産する場合はカップの口部を２ヶ所とらえてセットする２点支持方式の支持体が小型になり袋部より小さく小型の支持体でありコーヒー粉を充填し袋の三辺を製袋するのに適するが支持体が小型であるため袋部の大部分をカップ内に入れ重心を低くしなければ安定してセットできず又袋部の大半がカップ内のお湯に浸るためドリップ性が低い問題も生じた〔実開平７−２２３〕 A two-point support system in which the mouth of the cup is set at two locations when it is produced in a bag-making type filling facility in which three sides of a belt-like sheet having water-passability are heat-sealed by heat sealing or the like. Is a small support that is smaller than the bag and suitable for filling coffee powder and making three sides of the bag, but because the support is small, most of the bag is placed in the cup and the center of gravity is increased. If it is not lowered, it cannot be set stably, and the bag part is soaked in hot water in the cup.

袋部をカップ上に浮かせてセットする支持体ではカップの口部をとらえる係止部に一定の強度を必要とするため支持体に使用する部材は厚手の硬性を有したものを使用しなければならず製袋方式の充填機の場合帯状のシートにあらかじめ支持体を取り付けてロール状に巻き充填機にセットして引き出しながら帯状シートを２枚折した三辺をヒートシールするためこの工程の中で硬性を有した支持体では折れ曲がり変形するなどして支持体としての機能に問題が生じやすくカップ上にセットするため支持体が大型になる事も変形し折れ曲がりやすく製袋方式の充填機には適さなかった。〔特開２００２−２３８７６７〕 In the support body that floats and sets the bag part on the cup, the locking part that catches the mouth part of the cup needs a certain strength. Therefore, the member used for the support body must be thick and hard. In the case of a bag-making type filling machine, a support is attached to the belt-like sheet in advance, the roll is wound on the filling machine, and the three sides of the belt-like sheet folded while being pulled out are heat sealed. In the case of a bag-filling type filling machine, it is easy to bend and deform when the support is hard and is deformed. It was not suitable. [JP 2002-238767]

通水濾過性を有した帯状のシートをヒートシール等により三辺を封じる製袋方式による充填設備には帯状のシートあらかじめ取り付けてある支持体は柔軟性を有した支持体が適しているが柔軟性を有した支持体の部材でカップ上に袋部を浮かせセットするには全体を支える大きな支持力を必要としこの支持力を支持体に構成させるには袋部全体を被覆するほどの大きな面積の支持体としなければならずコスト高となった。〔特開２００４−１７８５〕 For the filling equipment using a bag-making system that seals three sides of a belt-like sheet with water-passability by heat sealing etc., a flexible support is suitable for the support that is already attached to the belt-like sheet. In order to float and set the bag part on the cup with the support member having the property, a large support force is required to support the whole, and in order to configure this support force on the support body, the area large enough to cover the entire bag part It has to be used as a support body, and the cost is high. [JP 2004-1785]

そして本発明は上記目的を達成するために柔軟性を有した薄手の厚紙等の支持体で袋の外寸法と同じサイズで構成する事で生産工程を簡略化する製袋方式で生産できる方式タイプでありながら袋部をカップ上に浮かせて支持する高い支持力を構成する支持体とするために次の様にした、通水濾過性を有する柔軟なシートでフィルター袋２を構成し、これは底部に折り込み部１０を設けている、袋部支持体５はフィルター袋２の下部側を外側から２枚で前後からはさみ被覆しフィルター袋２の外壁面と一体化しておりフィルター袋２の両サイドの端部３で接続して構成したフィルター袋２は２枚の袋部支持体５の両側部１３をフィルター袋２の左右の端部３に達して筒状の袋部支持体５を構成しフィルター袋２の袋形を形成保持し、この袋部支持体５は中心の縦方向に位置したセンターフレーム８の折り曲げ部１１から左右に各伸び出た２枚の支持アーム１０を有しこの支持アーム１０の下部の先端側には下方に向いたカップの口部をとらえる切り込み溝１２を各有している、この袋部支持体５はセンターフレーム８から左右に伸び出た支持アーム１０の周囲を上端フレーム９とサイドフレーム６と底フレーム７で構成しフィルター袋２の外壁面と一体化してフィルター袋２の下部側で筒型を構成してフィルター袋２の袋型を保持しながら同時に左右に伸び出る支持アーム１０をセンターフレーム８で支えている、この袋部支持体５は柔軟性を有した薄手の厚紙等の部材で構成しながら袋部全体をカップ上に袋型を保持し支える大きな支持力を構成させるために巾が狭く細長いこの上端フレーム９やサイドフレーム６及び底フレーム７とセンターフレーム８でも高い形成保持力を生じさせるためにフィルター袋２の外壁面に一体に取り付けてフィルター袋２自体の引っ張り強度との構成により袋形を保持する保持力を高めている同時にセンターフレーム８の固定性も高まり支持アーム１０の支持性も高める支持アーム１０の周囲に構成したこの上端フレーム９やサイドフレーム６及び底フレーム７を巾の狭い細長い構成配置として支持アーム１０に大きな面積を確保して支持アーム１０を大型化することで袋部をカップ上に保持する支持アーム１０の支持力も高め又大型化にする事で折り曲げ部１１から下端に設けたカップの口部をとらえる切り込み溝１２までの距離も大きくなるため支持アーム１０の開き加減でカップ口径の大小に適応させている、さらにフィルター袋２は下部側を袋部支持体５に袋型を保持され上方に伸び出て必要な袋容量を構成し形成している。 And the present invention is a system type that can be produced by a bag making system that simplifies the production process by configuring it with the same size as the outer dimension of the bag with a flexible support such as thin cardboard to achieve the above object However, the filter bag 2 is composed of a flexible sheet having water-passing filterability as described below in order to make a support body that has a high supporting force for floating and supporting the bag portion on the cup. The bag support 5 provided with a folded portion 10 at the bottom is covered with two pieces of the lower side of the filter bag 2 from the outside and is integrated with the outer wall surface of the filter bag 2 on both sides of the filter bag 2. The filter bag 2 constructed by connecting the end portions 3 of the two ends of the two bag portion support bodies 5 reaches the left and right end portions 3 of the filter bag 2 to form a cylindrical bag portion support body 5. The bag shape of the filter bag 2 is formed and held, and this bag part support The body 5 has two support arms 10 each extending left and right from the bent portion 11 of the center frame 8 positioned in the longitudinal direction of the center, and a cup facing downward is provided at the lower end side of the support arm 10. Each of the bag support members 5, each having a notch groove 12 for catching the mouth portion, is constituted by a top frame 9, a side frame 6, and a bottom frame 7 around a support arm 10 extending from the center frame 8 to the left and right. A cylindrical frame is formed on the lower side of the filter bag 2 so as to be integrated with the outer wall surface of the filter bag 2, and the support arm 10 extending left and right is supported by the center frame 8 while holding the bag shape of the filter bag 2. The bag support 5 is formed of a member such as thin cardboard having flexibility, and has a narrow and narrow width so as to form a large support force for holding and supporting the bag mold on the cup. The frame 9, the side frame 6, the bottom frame 7, and the center frame 8 are also integrally attached to the outer wall surface of the filter bag 2 in order to generate a high holding force, and the bag shape is maintained by the configuration of the tensile strength of the filter bag 2 itself. The upper frame 9, the side frame 6, and the bottom frame 7 that are formed around the support arm 10 that increases the holding force and at the same time enhances the fixability of the center frame 8 and increases the supportability of the support arm 10. As the arrangement, the support arm 10 has a large area and the support arm 10 is enlarged to increase the support force of the support arm 10 that holds the bag portion on the cup. Since the distance to the notch groove 12 that catches the mouth of the cup is also increased, the opening of the support arm 10 can be used to adjust the cup diameter. Further, the filter bag 2 is formed so as to form a necessary bag capacity by holding the bag shape with the bag support 5 on the lower side and extending upwards.

フィルター袋２の袋形を保持するための袋部支持体５が柔軟性を有した薄手の厚紙等の部材で構成した上端フレーム９やサイドフレーム６及び底フレーム７さらにセンターフレーム８からなる巾の狭い細長の形状で構成していても高いフィルター袋２の袋形の形成及びその保持力を生じさせるためこの内壁面とフィルター袋２の外壁面とを一体に取り付けてフィルター袋２の部材の引張り強度との組み合わせによりフィルター袋２の袋形の形成及び保持力を構成させた袋部支持体５としてカップ上にセットした時の支持アーム１０を保持するセンターフレーム８の支持力も同時に高められている。 The bag support 5 for holding the bag shape of the filter bag 2 has a width composed of a top frame 9, a side frame 6, a bottom frame 7, and a center frame 8 made of a member such as thin cardboard having flexibility. In order to generate a bag shape of the high filter bag 2 and its holding force even if it is constituted by a narrow and slender shape, the inner wall surface and the outer wall surface of the filter bag 2 are attached integrally to pull the member of the filter bag 2 The support force of the center frame 8 that holds the support arm 10 when it is set on the cup as the bag portion support body 5 that forms the bag shape and the holding force of the filter bag 2 by the combination with the strength is simultaneously enhanced. .

フィルター袋２の袋形を保持しカップ上にセットして支持する袋部支持体５は巾が狭く細長い上端フレーム９やサイドフレーム６及び底フレーム７さらにセンターフレーム８で構成しフィルター袋２の部材の引っ張り強度との組み合わせで高い硬性強度を構成しているため袋部支持体５の全体面積内で支持アーム１０に使用する面積を大きく取り構成し確保できるため袋部支持体５の部材が柔軟性を有した薄手の厚紙等であってもカップ上にセットした時に必要な大きな支持力を支持アーム１０に構成でき同時にカップ口径の大小に対しても支持アーム１０が大型であるため支持アーム１０の折り曲げ部１１からの開き加減でセット範囲を大きく変化させて対応できる様になる。 The bag support 5 that holds the bag shape of the filter bag 2 and supports it by setting it on the cup comprises a narrow and narrow upper end frame 9, side frame 6, bottom frame 7, and center frame 8, and a member of the filter bag 2. Since it has a high hardness strength in combination with the tensile strength of the bag, the area used for the support arm 10 can be made large and secured within the entire area of the bag support 5, so that the member of the bag support 5 is flexible. The support arm 10 can be configured to have a large support force necessary for setting it on a cup even if it is a thin cardboard having the property, and the support arm 10 is large even with respect to the size of the cup caliber. The set range can be greatly changed by opening and subtracting from the bent portion 11 of the lens.

フィルター袋２の外壁面に一体に取り付け設けた２枚の袋部支持体５がフィルター袋２の左右の端部３を接合して構成したフィルター袋２を介してフィルター袋２の下部側で筒状の支持体を構成しているためフィルター袋２の口部１を開きフィルター袋２の下部側の袋部支持体５を筒状に形成する時２枚の袋部支持体５自体の左右両端部どうしを接合して筒形を形成する場合に比較して口部１及び袋部支持体５を筒型に開き形成する事がフィルター袋２の部材が袋部支持体５の部材より柔軟であるため容易になり又、生産工程上も２枚の袋部支持体５の左右両側部１３を接合した場合はフィルター袋２の左右両端部３の接合工程も含めて２重の端部接合工程となるが２枚の袋部支持体５をフィルター袋２の外壁面に取り付けてフィルター袋２の左右の両端部３だけを接合する場合は同時に２枚の支持体５も筒状に構成でき端部接合工程が一工程に簡略する事が可能になる。 Two bag portion supports 5 integrally attached to the outer wall surface of the filter bag 2 are joined to the left and right end portions 3 of the filter bag 2 and the tube is formed on the lower side of the filter bag 2 through the filter bag 2. Since the mouth portion 1 of the filter bag 2 is opened and the bag portion support 5 on the lower side of the filter bag 2 is formed into a cylindrical shape, the left and right ends of the two bag portion supports 5 themselves are formed. The member of the filter bag 2 is more flexible than the member of the bag part support 5 by forming the mouth part 1 and the bag part support body 5 in a cylindrical shape as compared with the case where the parts are joined to form a cylindrical shape. In the production process, when the left and right side portions 13 of the two bag portion supports 5 are joined, the double end portion joining step including the joining step of the left and right end portions 3 of the filter bag 2 is facilitated. However, the two bag support members 5 are attached to the outer wall surface of the filter bag 2 so that the filter bag 2 Configuration can end joining step at the same time the two support 5 also cylindrical in the case of joining only the right and left end portions 3 becomes possible to simplify one step.

フィルター袋２の底部に折り込み部４を設けているため下部側に設けた袋部支持体５を筒状に開いた時フィルター袋２の底面積分をこの折り込み部４が開き底面を構成するため、袋部支持体５より下方にフィルター袋２が伸び出て位置し底面積分を構成する必要がなくお湯を注いだ時にカップ内の湯面にフィルター袋２の底部が袋部支持体５の下端部より下方に伸び出ないためにカップ内の湯面にフィルター袋２の底部が接する事がなくドリップ性が確保できる。 Since the folding part 4 is provided at the bottom of the filter bag 2, the bottom part integration of the filter bag 2 is formed when the bag part support 5 provided on the lower side is opened in a cylindrical shape, so that the folding part 4 opens and constitutes the bottom surface. The filter bag 2 extends below the bag support 5 and does not need to constitute a bottom integral, so that when the hot water is poured, the bottom of the filter bag 2 is the bottom of the bag support 5 when the hot water is poured into the cup. Since it does not extend further downward, the bottom of the filter bag 2 does not come into contact with the hot water surface in the cup, and drip properties can be secured.

フィルター袋２の下部側を袋部支持体５が筒型を形成し４辺の支持アーム１０がカップ口部をとらえ支持しフィルター袋２の下部側を固定支持しているため袋部支持体５から上方にフィルター袋２が伸び出て袋の上部側を構成して必要な袋容量を確保構成しており従来の様に袋部全体を被覆構成した支持体がカップ口部より大きな構成の支持体など又、袋の口部を形成し、さらに支持体が下方に伸び出て構成した支持体は多くの支持体面積を必要とするのに比較しフィルター袋２の下部側だけに袋部支持体５を構成配置するため支持体面積が少なく低コスト化になる。 Since the bag portion support 5 forms a cylindrical shape on the lower side of the filter bag 2 and the support arms 10 on the four sides catch and support the cup mouth portion, and support the lower side of the filter bag 2 fixedly, the bag portion support 5 The filter bag 2 extends upward from the upper side to constitute the upper side of the bag to secure the necessary bag capacity, and the support that covers and covers the entire bag portion as in the past is larger than the cup mouth portion. In addition, the support formed by forming the mouth part of the bag and extending the support downward further supports the bag part only on the lower side of the filter bag 2 as compared to requiring a large support area. Since the body 5 is configured and arranged, the support area is small and the cost is reduced.

以下、本発明の実施の形態を図１〜図５に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to FIGS.
