Description

抽出バッグ用シートExtraction bag seat
　本発明は、ティーバッグなどの抽出用バッグの製造に使用される抽出バッグ用シートに関する。 The present invention relates to an extraction bag sheet used for manufacturing an extraction bag such as a tea bag.
　抽出バッグとしては、例えば、紅茶のティーバッグがあり、簡単に紅茶を抽出することができ、廃棄なども容易に行うことができるため、広く普及している。このような簡便さから、紅茶以外にも緑茶、コーヒーなど嗜好飲料用の抽出バッグが販売されている。
　このような抽出バッグは、ロール状に巻き取った抽出バッグ用シートを自動ティーバッグ包装機に装着して製造されることが多く、この抽出バッグ用シートは、長尺帯状の通水性濾過シートの長手方向に所定間隔で、先端に摘み片を備えた吊り糸を横断させて配したものが一般的に用いられている。 As an extraction bag, for example, there is a tea bag of black tea, and it can be easily extracted, and can be easily disposed of. Because of such simplicity, extraction bags for beverages such as green tea and coffee are sold in addition to black tea.
Such an extraction bag is often manufactured by mounting an extraction bag sheet wound up in a roll shape on an automatic tea bag packaging machine, and this extraction bag sheet is a long band-shaped water-permeable filtration sheet. In general, a string that is arranged by traversing a hanging thread provided with a knob at the tip at a predetermined interval in the longitudinal direction is used.
　例えば、このような抽出バッグ用シートとして、下記特許文献１には、透液性を有した長尺なシートと、先端にタグが取り付けられ、このタグと後端とがシートに止着されることにより、シートを横断するようにシートに取り付けられた摘み糸とを備え、前記摘み糸の中間部分に弛み部が設けられていることを特徴とする包材が開示されている。 For example, as a sheet for such an extraction bag, in Patent Document 1 below, a long sheet having liquid permeability, a tag is attached to the front end, and the tag and the rear end are fixed to the sheet. Thus, there is disclosed a packaging material comprising a pick thread attached to a sheet so as to cross the sheet, and a slack portion is provided in an intermediate portion of the pick thread.
　下記特許文献２には、通液性を有した長尺なシートと、吊り糸及びタグを有し、吊り糸の一端がタグに止着され、中間部分がタグに巻回された状態でシートを横断するように前記タグ及び吊り糸の他端がシートに止着された吊り下げ用部材とを備えていることを特徴とする包材が開示されている。 The following Patent Document 2 includes a long sheet having liquid permeability, a hanging thread and a tag, one end of the hanging thread being fixed to the tag, and a middle part wound around the tag. A wrapping material is disclosed, characterized in that the tag and the hanging thread are attached to the sheet at the other end of the tag and the hanging thread so as to cross.
　下記特許文献３には、吊し糸と接着したタグが通水濾過性シートの長手方向に所定間隔で複数取り付けられている抽出バッグ用シートであって、タグが複数列に配置されている抽出バッグ用シートが開示されている。 Patent Document 3 listed below is an extraction bag sheet in which a plurality of tags bonded to a hanging thread are attached at predetermined intervals in the longitudinal direction of a water-permeable filter sheet, and the tags are arranged in a plurality of rows. A bag seat is disclosed.
特開平１０－１５７７１０号公報JP-A-10-157710 特開２００２－２１１６４１号公報JP 2002-211641 A 特開２００８－６８８９１号公報JP 2008-68891 A
　抽出バッグ用シートは、上記特許文献１～３に開示されているように、吊り糸を通水性濾過シート上に横断させてあり、吊り糸が露出しているため、抽出バッグ製造時にシートとともに吊り糸が切断されるおそれがあった。特に吊り糸を長くした場合は、製造時に切断されるおそれが高まるものであった。
　また、上記特許文献１～３に記載の抽出バッグ用シートは、吊り糸の基端部とタグを超音波溶着などでシ－ト上に止着し、吊り糸をシートの幅方向に架け渡してあるため、抽出バッグ用シートをロール状に巻き取った場合、きつく巻き取るとシートが歪み、吊り糸が剥がれ落ちてしまうおそれがあった。そのため、緩く巻き取らなければならず、ロール径が膨らみ巻数が少なくなる。そのため、包装機に装着できるロ－ル径は一定であるため、一つのロールから製造できる抽出バッグの数も少量になってしまうものであった。 As disclosed in the above-mentioned patent documents 1 to 3, the extraction bag sheet is crossed on the water filtration sheet and the hanging thread is exposed. Therefore, the extraction bag sheet is suspended together with the sheet when the extraction bag is manufactured. There was a risk of the yarn being cut. In particular, when the hanging thread is lengthened, the possibility of being cut at the time of manufacture is increased.
The extraction bag sheet described in Patent Documents 1 to 3 has the base end of the hanging thread and the tag fixed on the sheet by ultrasonic welding or the like, and the hanging thread is bridged in the width direction of the sheet. Therefore, when the extraction bag sheet is wound up in a roll shape, the sheet may be distorted if it is wound up tightly, and the hanging thread may be peeled off. Therefore, it must be wound up loosely, the roll diameter swells and the number of windings decreases. For this reason, since the roll diameter that can be mounted on the packaging machine is constant, the number of extraction bags that can be manufactured from one roll is also small.
　そこで、本発明の目的は、吊り糸を長くしても、抽出バッグ製造時に吊り糸が切断され難い抽出バッグ用シートを提供せんとするものである。 Therefore, an object of the present invention is to provide an extraction bag sheet in which the hanging thread is difficult to be cut during the manufacture of the extraction bag even if the hanging thread is lengthened.
　本発明の抽出バッグ用シートは、先端部に摘み片を固着し、基端部を長尺帯状の通水性濾過シート上に固着した吊り糸を、螺旋状に纏めて通水性濾過シート上に配し、この吊り糸を覆うように摘み片を通水性濾過シート上に剥離可能に固着したことを特徴とする。 The sheet for an extraction bag of the present invention has a thread attached to a distal end portion, and a hanging thread having a proximal end portion fixed to a long band-shaped water-permeable filtration sheet is spirally arranged on the water-permeable filtration sheet. The picking piece is fixed to the water filtration sheet so as to cover the hanging thread so as to be peeled off.
　本発明の抽出バッグ用シートは、摘み片で吊り糸を覆うようにしたため、吊り糸が露出せず、抽出バッグ製造時に吊り糸が切断されるおそれがない。そのため、吊り糸を１６０ｍｍ以上など長くしても切断されるおそれがない。
　また、従来では、吊り糸をシートの幅方向に架け渡していたため、シートをロ－ル状に強く巻き取ると吊り糸の張力によりシ－トが歪み、摘み片が剥がれ落ちてしまうことがあったが、本発明の抽出バッグ用シートは、通水性濾過シートと摘み片の間に吊り糸を収容したため、強く張力をかけてもシ－トが歪み難く、摘み片も剥がれ落ち難く、抽出バック用シートをロ－ル状に強く巻き取ることができ、従来と比べて一つのロールあたりの巻数を増加させることができ、製造できる抽出バッグの数を増やすことができる。 In the extraction bag sheet of the present invention, the hanging thread is covered with the knob, so that the hanging thread is not exposed, and there is no possibility that the hanging thread is cut when the extraction bag is manufactured. Therefore, there is no possibility of being cut even if the hanging thread is made longer than 160 mm.
In addition, conventionally, the hanging thread is stretched in the width direction of the sheet. Therefore, if the sheet is strongly wound in a roll shape, the sheet may be distorted due to the tension of the hanging thread and the knob may be peeled off. However, since the sheet for the extraction bag of the present invention accommodates the hanging thread between the water-permeable filtration sheet and the knob, the sheet is not easily distorted even when a strong tension is applied, and the knob is not easily peeled off. The sheet for use can be strongly wound in a roll shape, the number of windings per roll can be increased as compared with the conventional sheet, and the number of extraction bags that can be manufactured can be increased.

　以下、本発明の一実施形態の抽出バッグ用シートについて説明する。但し、本発明は、この実施形態に限定されるものではない。 Hereinafter, an extraction bag sheet according to an embodiment of the present invention will be described. However, the present invention is not limited to this embodiment.
　本発明の一実施形態の抽出バッグ用シート１は、先端部に摘み片４を固着し、基端部３ａを長尺帯状の通水性濾過シート２上に固着した吊り糸３を、螺旋状に纏めて通水性濾過シート２上に配し、この吊り糸３を覆うように摘み片４を通水性濾過シート２上に剥離可能に固着したものである。 The sheet 1 for an extraction bag according to an embodiment of the present invention has a hanging thread 3 in which a knob 4 is fixed to a distal end portion and a base end portion 3a is fixed on a long water-permeable filtration sheet 2 in a spiral shape. They are collectively arranged on the water-permeable filtration sheet 2 and the knob 4 is fixed to the water-filtration sheet 2 so as to be peeled off so as to cover the hanging thread 3.
　通水性濾過シート２の材質は、透水性を備えていれば任意である。例えば、ポリエステル、ナイロン、ポリエチレン、ポリプロピレン等の合成繊維、または不織布、多孔質フィルムなどからなるシート乃至フィルムを用いることができる。中でも、吊り糸及び摘み片を熱溶着又は超音波溶着などの融着によって固着できる材質が好ましい。
　通水性濾過シート２は、三角錐状（テトラ状）や平型状などに製袋し、内部に緑茶葉、紅茶葉、烏龍茶葉、コーヒー豆、削り節などの抽出物を充填して抽出バッグを製造することができる。
　通水性濾過シート２は、幅１２０ｍｍ～１８０ｍｍのものを用いることができ、また、厚み０．０１ｍｍ～０．１６ｍｍ、好ましくは厚み０．０６ｍｍ～０．１０ｍｍのものを用いることができる。 The material of the water-permeable filtration sheet 2 is arbitrary as long as it has water permeability. For example, a synthetic fiber such as polyester, nylon, polyethylene, or polypropylene, or a sheet or film made of a nonwoven fabric or a porous film can be used. Among them, a material capable of fixing the hanging thread and the knob piece by fusion such as heat welding or ultrasonic welding is preferable.
The water-permeable filtration sheet 2 is formed into a triangular pyramid shape or a flat shape, and filled with extracts such as green tea leaves, black tea leaves, oolong tea leaves, coffee beans, shavings, etc. Can be manufactured.
The water-permeable filter sheet 2 can have a width of 120 mm to 180 mm, and can have a thickness of 0.01 mm to 0.16 mm, preferably 0.06 mm to 0.10 mm.
　吊り糸３の材質は、特に限定するものではない。例えばポリエステル、ナイロン、ポリエチレン、ポリプロピレン等の熱溶着又は超音波溶着が可能な合成繊維からなる糸を用いることができる。なかでも、巻いても折り跡が付きにくく、元の直線状態に戻り易い糸を使用するが好ましく、直線回復性を測定することで確認できる。 The material of the hanging thread 3 is not particularly limited. For example, it is possible to use a thread made of synthetic fiber that can be thermally welded or ultrasonically welded, such as polyester, nylon, polyethylene, and polypropylene. Among them, it is preferable to use a thread that hardly folds even when wound and easily returns to the original straight state, and this can be confirmed by measuring the straight line recoverability.
　吊り糸３は、マグカップなどでも使い易いように、長さ１６０ｍｍ以上にするのが好ましく、長さ１６０ｍｍ～２６０ｍｍにするのが特に好ましく、１７０ｍｍ～２００ｍｍにするのがより好ましい。 The hanging thread 3 is preferably 160 mm or longer, particularly preferably 160 to 260 mm, and more preferably 170 to 200 mm so that the hanging thread 3 can be easily used in a mug or the like.
　吊り糸３は、通水性濾過シート２の一方の縁部に沿い、適宜間隔で配することができる。この間隔は、３０ｍｍ～１００ｍｍ、特に４５ｍｍ～８０ｍｍが好ましい。また、図３に示すように、両方の縁部に沿い長手方向に交互に配することもできる。 The hanging thread 3 can be arranged along the one edge of the water-permeable filtration sheet 2 at appropriate intervals. This interval is preferably 30 mm to 100 mm, particularly 45 mm to 80 mm. Moreover, as shown in FIG. 3, it can also arrange | position alternately along a longitudinal direction along both edges.
　吊り糸３の先端部には、摘み片４を固着してある。
　摘み片４は、指で摘んで抽出バッグ１を持ち上げるための部材であり、指先で摘み易い形状であるのが好ましい。例えば平面視した際に、円形状、ハート形、クローバ形、長円状、正方形状又は長方形状などの形状を呈するシート状又は平板状に形成することができる。
　摘み片４の材質は任意である。例えば、紙の片面にポリエチレンなどの樹脂をラミネートした熱溶着又は超音波溶着が可能なラミネート紙片を用いるのが好ましい。
　摘み片４の厚みは、好ましくは０．０９ｍｍ～０．３６ｍｍ、より好ましくは０．１８ｍｍ～０．２１ｍｍである。 A knob 4 is fixed to the tip of the hanging thread 3.
The knob 4 is a member for picking up with the finger and lifting the extraction bag 1 and preferably has a shape that can be easily picked up with the fingertip. For example, it can be formed in a sheet shape or a flat plate shape having a circular shape, a heart shape, a clover shape, an oval shape, a square shape or a rectangular shape when viewed in plan.
The material of the knob 4 is arbitrary. For example, it is preferable to use a laminated paper piece capable of thermal welding or ultrasonic welding in which a resin such as polyethylene is laminated on one side of the paper.
The thickness of the knob 4 is preferably 0.09 mm to 0.36 mm, more preferably 0.18 mm to 0.21 mm.
　吊り糸３は、例えば図２に示すように、螺旋状に纏めてシート２の表面上に配するのが好ましい。このように吊り糸３を螺旋状に纏めて配すれば、摘み片４を持ち上げた際に、絡み合うことなく、吊り糸３を伸ばすことができる。
　ただし、ここでの「螺旋状」には、例えば図２に示すように、円形乃至長円形が旋回方向と直交する方向にズレながら連続する螺旋状のほか、旋回方向の同心円方向にズレながら連続する渦巻状なども包含する意味である。
　また、吊り糸３同士ができるだけ重ならないように纏めるのが好ましい。例えば、図２に示すように、長円形を横にずらせて纏めるのが好ましい。
　さらにまた、基端部３ａをシート２の表面に固着した部分を覆うように、吊り糸３を纏めてもよいが、吊り糸を直線状態に戻り易くする観点から、図２に示すように、基端部３ａをシート２の表面に固着した部分から離れた位置で吊り糸３を纏めるのが好ましい。
　通水性濾過シ－ト２を、ロ－ル状に巻き取る際の安定性の観点から吊り糸３の基端部３ａの取り付け位置は、シ－ト２の幅を１００とした時、長手方向の一方の縁部から５～４５の位置が好ましく、特に１２～４５の位置が好ましい。
　また、１ロ－ルあたりから製造できる抽出バッグの数を増やすためには、図３に示すように、吊り糸３の基端部３ａを長手方向の両縁部から５～４５の位置に交互に取り付けることで、ロ－ル径が小さくなり、ロ－ル形状も安定する。 For example, as shown in FIG. 2, the hanging thread 3 is preferably arranged on the surface of the sheet 2 in a spiral shape. Thus, if the hanging thread 3 is arranged in a spiral shape, the hanging thread 3 can be stretched without being entangled when the knob 4 is lifted.
However, in this “spiral shape”, for example, as shown in FIG. 2, a circular shape or an oval shape is continuous while being shifted in a direction perpendicular to the turning direction, and continuously being shifted in a concentric direction of the turning direction. It also includes a spiral shape.
Further, it is preferable that the hanging yarns 3 are gathered together so as not to overlap as much as possible. For example, as shown in FIG. 2, it is preferable that the ellipses are gathered by shifting horizontally.
Furthermore, the hanging thread 3 may be bundled so as to cover the portion where the base end portion 3a is fixed to the surface of the sheet 2, but from the viewpoint of facilitating the return of the hanging thread to the linear state, as shown in FIG. It is preferable that the hanging yarns 3 are gathered at a position away from a portion where the base end portion 3 a is fixed to the surface of the sheet 2.
From the viewpoint of stability when winding the water-permeable filtration sheet 2 in a roll shape, the attachment position of the base end portion 3a of the hanging thread 3 is the longitudinal direction when the width of the sheet 2 is 100 A position of 5 to 45 from one edge portion of these is preferable, and a position of 12 to 45 is particularly preferable.
In order to increase the number of extraction bags that can be manufactured per roll, as shown in FIG. 3, the base end portion 3a of the hanging thread 3 is alternately placed at positions 5 to 45 from both edges in the longitudinal direction. By attaching to the roll, the roll diameter is reduced and the roll shape is stable.
　摘み片４は、上述のように纏めた吊り糸３を覆うように、シート２の表面に剥離可能に固着してある。
　このようにすることにより、このシート１から抽出バッグを製造した際、摘み片４を持ち上げれば、吊り糸３が伸び、バッグ部を吊り下げることができ、従来のように、吊り糸を解いたりする手間がかからず操作性がよくなる。 The knob 4 is detachably fixed to the surface of the sheet 2 so as to cover the hanging thread 3 gathered as described above.
In this way, when the extraction bag is manufactured from this sheet 1, if the knob 4 is lifted, the hanging thread 3 can be extended and the bag portion can be hung. The operability is improved because there is no time and effort required.
　ただし、摘み片４により、吊り糸３の全部が覆われる必要はなく、吊り糸３の一部は露出していてもよい。このように吊り糸３が摘み片４により覆われていれば、吊り糸３が製造時に切断されるおそれがない。 However, it is not necessary to cover the entire hanging thread 3 with the knob 4, and a part of the hanging thread 3 may be exposed. Thus, if the hanging thread 3 is covered with the knob 4, there is no possibility that the hanging thread 3 is cut during manufacture.
　摘み片４をシート２の表面に固着する手段は任意であるが、熱溶着又は超音波溶着などを採用するのが好ましい。
　また、摘み片４をシート２の表面に固着する少なくとも２つの固着部５，５で前記吊り糸３を挟むようにするのが好ましい。このようにすれば、吊り糸３が自然に解けてしまうことを防ぐことができる。 A means for fixing the knob 4 to the surface of the sheet 2 is arbitrary, but it is preferable to employ heat welding or ultrasonic welding.
Further, it is preferable that the hanging thread 3 is sandwiched between at least two fixing portions 5 and 5 that fix the knob 4 to the surface of the sheet 2. In this way, it is possible to prevent the hanging thread 3 from being naturally unwound.
　摘み片４は、吊り糸３を覆いながらシート２の表面に剥離可能に固着した状態において、図４に示すように、摘み片４の膨らみｔが、表面から３ｍｍ以内にするのが好ましく、２ｍｍ以内にするのがより好ましい。これにより、巻数を増加させることができ、従来と比べて一つのロールから製造できる抽出バッグの数を増やすことができる。例えば、上記したように、吊り糸３同士ができるだけ重ならないように、円形乃至長円形を横にずらせながら纏めることにより上記膨らみにすることができる。 As shown in FIG. 4, in the state where the knob 4 is peelably fixed to the surface of the sheet 2 while covering the hanging thread 3, it is preferable that the bulge t of the knob 4 is within 3 mm from the surface. It is more preferable to make it within. Thereby, the number of windings can be increased, and the number of extraction bags that can be manufactured from one roll can be increased as compared with the prior art. For example, as described above, the swollen yarns 3 can be brought into the bulge by gathering them while shifting the circular shape or the oval shape to the side so that they do not overlap each other as much as possible.
　抽出バッグ用シート１は、先端部に摘み片４を固着し、基端部３ａを長尺帯状の通水性濾過シート２上に固着した吊り糸３を、螺旋状に纏めて通水性濾過シート２上に配した後、この吊り糸３を覆うように摘み片４を通水性濾過シート２上に剥離可能に固着して製造することができる。
　例えば、先端部に摘み片４を固着した吊り糸３を絡ませず且つ重ならないように纏めるため、円柱状の棒材などに少しずつずらしながら螺旋状に巻き付けておき、吊り糸３の基端部３ａの取り付け位置は、通水性濾過シート２の幅を１００とした時、一方の長手縁部に近い方から好ましくは５～４５の位置、より好ましくは１２～４５の位置に超音波溶着などで固着した後、棒材を抜き取り、摘み片４を吊り糸３上に被せながら摘み片４を超音波溶着などで固着することにより製造することができる。この棒材を平板状にしたり、複数本にしたりすれば吊り糸３を長円状にしやすくなる。また、固着部５は、少なくとも２つ設け、吊り糸３を挟み込む位置に設けるのが好ましい。 The extraction bag sheet 1 is a water-permeable filtration sheet 2 in which a hanging piece 3 having a knob 4 fixed to a distal end portion and a base end portion 3a fixed on a long band-like water-permeable filtration sheet 2 is spirally collected. After being arranged on the top, the knob 4 can be peeled and fixed on the water filtration sheet 2 so as to cover the hanging thread 3.
For example, in order to collect the hanging thread 3 with the knob 4 fixed to the tip part so as not to be entangled and overlapped with each other, it is spirally wound around a cylindrical bar or the like, and the proximal end of the hanging thread 3 3a is attached by ultrasonic welding or the like, preferably from 5 to 45, more preferably from 12 to 45, from the side closer to one longitudinal edge when the width of the water-permeable filtration sheet 2 is 100. After fixing, it can be manufactured by pulling out the bar and fixing the knob 4 by ultrasonic welding or the like while covering the knob 4 on the hanging thread 3. If this bar is formed into a flat plate shape or a plurality of bars, the hanging thread 3 can be easily formed into an oval shape. Moreover, it is preferable to provide at least two fixing portions 5 at positions where the hanging thread 3 is sandwiched.
　抽出バッグ用シート１を、従来からある包装充填機に装着して稼働させることにより、図５に示すような内部に抽出物を収容した三角錐状などの抽出バッグ６を製造することができる。この際、通水性濾過シート２は、図１又は図３に示す一点鎖線部分で切断されていく。
　抽出バッグ６は、図６に示すように、摘み片４を剥離して持ち上げれば、吊り糸３を伸ばすことができ、操作性がよいものである。 By attaching the extraction bag sheet 1 to a conventional packaging and filling machine and operating it, an extraction bag 6 having a triangular pyramid shape in which the extract is accommodated as shown in FIG. 5 can be manufactured. At this time, the water-permeable filtration sheet 2 is cut along the alternate long and short dash line portion shown in FIG. 1 or FIG.
As shown in FIG. 6, the extraction bag 6 can extend the hanging thread 3 if the knob 4 is peeled off and lifted, and has good operability.
　抽出バッグ用シート１は、吊り糸３が摘み片４で覆われているため、吊り糸４があまり露出せず、抽出バッグ製造時に吊り糸３が切断される恐れがない。そのため、吊り糸を１６０ｍｍ以上など長くしても切断されるおそれがないものである。
　また、本発明の抽出バッグ用シートは、通水性濾過シートと摘み片の間に吊り糸を収容したため、強く張力をかけても吊り糸が剥がれ落ち難く、抽出バック用シートを、ロ－ル状に強く巻き取り、巻数を増加させることができる。そのため、従来と比べて一つのロールから製造できる抽出バッグの数を増やすことができるものである。 In the extraction bag sheet 1, the hanging thread 3 is covered with the knob 4, so that the hanging thread 4 is not exposed so much and there is no fear that the hanging thread 3 is cut when the extraction bag is manufactured. Therefore, there is no possibility of being cut even if the hanging thread is made longer than 160 mm.
In addition, the extraction bag sheet of the present invention accommodates the hanging thread between the water-permeable filtration sheet and the knob, so that the hanging thread is not easily peeled off even when a strong tension is applied. Winding up strongly, the number of turns can be increased. Therefore, the number of extraction bags that can be manufactured from one roll can be increased as compared with the prior art.
　なお、本発明において、「Ｘ～Ｙ」（Ｘ，Ｙは任意の数字）と記載した場合、特にことわらない限り「Ｘ以上Ｙ以下」を意図し、「Ｘより大きくＹよりも小さいことが好ましい」旨の意図も包含する。 In the present invention, “X to Y” (X and Y are arbitrary numbers) is intended to mean “X or more and Y or less” unless otherwise specified, and may be “greater than X and less than Y”. The intention of “preferably” is also included.
