Description

本発明は、ドリップ方式でコーヒーや紅茶等を淹れるのに用いる嗜好性飲料抽出バッグに関し、特に注湯時に被抽出物が湯と共に溢れ出することがなく、しかも、風味のよいコーヒーや紅茶等を淹れることができる嗜好性飲料抽出用バッグに関するものである。   The present invention relates to a palatable beverage extraction bag used for brewing coffee, tea, or the like by a drip method, and in particular, an extractable material does not overflow with hot water during pouring, and also has a savory coffee, tea, etc. The present invention relates to a bag for extracting a palatable beverage that can be drunk.

従来より、不織布製等の抽出袋と、抽出袋の開口部側面を覆ってカップの縁に当接する紙製等の支持シートとよりなる嗜好性飲料抽出バッグが知られている。たとえば、特許文献１には、抽出袋１の表面に、抽出袋１よりもやや幅狭の支持シート４ａが設けられ、抽出袋１の裏面に同様の構成の支持シート４ｂが貼着されてなる嗜好性飲料抽出バッグが記載されている。そして、かかる嗜好性飲料抽出バッグを用いてコーヒー等をドリップしたときの状態は、図１に示すとおりである。   2. Description of the Related Art Conventionally, a palatability beverage extraction bag comprising an extraction bag made of non-woven fabric and a support sheet made of paper that covers the side surface of the opening of the extraction bag and abuts the edge of the cup is known. For example, in Patent Document 1, a support sheet 4 a slightly narrower than the extraction bag 1 is provided on the surface of the extraction bag 1, and a support sheet 4 b having the same configuration is attached to the back surface of the extraction bag 1. A palatable beverage extraction bag is described. And the state when drip coffee etc. using this palatability drink extraction bag is as showing in FIG.

かかる嗜好性飲料抽出バッグを用いた場合、抽出袋１の材料として通湯性に劣る材料を用いると、注湯時に湯と共に被抽出物が抽出袋１の口から溢れ出すという欠点があった。また、抽出袋１の材料として、通湯性に優れた材料を用いると、注湯時に被抽出物が溢れ出すことはないが、湯が被抽出物と接触している時間が短く、風味のよいコーヒー等を淹れることができないという欠点があった。   When such a palatable beverage extraction bag is used, if an inferior hot-water-permeable material is used as the material for the extraction bag 1, there is a drawback that the extractable material overflows from the mouth of the extraction bag 1 together with hot water during pouring. Moreover, when the material excellent in hot water permeability is used as the material of the extraction bag 1, the extract does not overflow when pouring, but the time that the hot water is in contact with the extract is short, There was a drawback that it was not possible to brew good coffee.

特開２０１０−１１０３３５号公報JP 2010-110335 A

本発明は、嗜好性飲料抽出バッグの材料を工夫して、注湯時に被抽出物が抽出袋の口から溢れ出すこともなく、また風味のよいコーヒー等を淹れることができる嗜好性飲料抽出バッグを提供するものである。   The present invention devised a material for a palatable beverage extraction bag, so that the extractables do not overflow from the mouth of the extraction bag during pouring, and a palatable beverage extraction that can brew delicious coffee or the like A bag is provided.

すなわち、本発明は、略四辺形の通湯性の抽出袋１と、前記抽出袋１の内面に貼着され、前記抽出袋１の口を封する、前記抽出袋１よりも通湯性に優れる濾過布２と、前記抽出袋１及び前記濾過布２によって密封された嗜好性飲料被抽出物３と、前記抽出袋１の表面に設けられた支持シート４ａ及び４ｂとからなり、前記支持シート４ａ及び４ｂは、カップの縁に係合しうる引き起こし片５ａ及び５ｂを具備しており、前記引き起こし片５ａ及び５ｂをカップの縁に係合して、前記抽出袋１を開いて前記濾過布２へ注湯して抽出しうる構成とするとともに、前記濾過布２の、前記抽出袋１の内面への貼着部位６ａは、前記抽出袋１の内面で、前記支持シート４ａに対向する部分であって前記支持シート４ａの上縁以下の位置に貼着され、前記濾過布２の、前記抽出袋１の内面への貼着部位６ｂは、前記抽出袋１の内面で、前記支持シート４ｂに対向する部分であって前記支持シート４ｂの上縁以下の位置に貼着された嗜好性飲料抽出バッグに関するものである。 That is, the present invention has a substantially quadrilateral hot water extraction bag 1 and is attached to the inner surface of the extraction bag 1 and seals the mouth of the extraction bag 1. The support sheet is composed of an excellent filter cloth 2, the extraction bag 1 and a palatable beverage extract 3 sealed by the filter cloth 2, and support sheets 4a and 4b provided on the surface of the extraction bag 1. 4a and 4b are provided with trigger pieces 5a and 5b that can be engaged with the edge of the cup. The trigger pieces 5a and 5b are engaged with the edge of the cup to open the extraction bag 1 and the filter cloth. The portion 6a of the filter cloth 2 attached to the inner surface of the extraction bag 1 is a portion facing the support sheet 4a on the inner surface of the extraction bag 1 is stuck at a position of the upper edge below the support sheet 4a a is, the Over-fabric 2, bonded portion 6b to the extraction bag 1 inner surface, the inner surface of the extraction bag 1, bonded to the position of the upper edge below the support sheet 4b a portion facing the support sheet 4b The present invention relates to a worn beverage extraction bag.

抽出袋１及び濾過布２の材料としては、不織布や編織物等が用いられる。そして、抽出袋１には通湯性に劣る材料が用いられ、濾過布２には通湯性に優れる材料が用いられる。本発明において、「通湯性に劣る」とか「通湯性に優れる」という意味は、相対的なものであり、抽出袋１の通湯速度が濾過布２の通湯速度よりも遅いということである。通湯速度は、抽出袋１及び濾過布２の材質や物性等で決定される。抽出袋１及び濾過布２共に不織布で構成されている場合、概ね、以下の要因によって通湯速度が決定される。（１）不織布の構成繊維が親水性であると通湯速度は速くなり、疎水性であると通湯速度は遅くなる。（２）不織布の構成繊維相互間の空隙が大きければ大きいほど通湯速度は速くなり、空隙が小さければ小さいほど通湯速度は遅くなる。（３）不織布の空隙率が高くなればなるほど通湯速度は速くなり、空隙率が低くなればなるほど通湯速度は遅くなる。（４）不織布の厚みが薄ければ薄いほど通湯速度は速くなり、厚みが厚ければ厚いほど通湯速度は遅くなる。これらの要因は概ねの要因であり、その他の要因によっても通湯速度は変動する。したがって、これらの各要因を調整して、抽出袋１には通湯速度の遅いもの（通湯性に劣るもの）を採用し、濾過布２には通湯速度の速いもの（通湯性に優れるもの）を採用する。   As a material for the extraction bag 1 and the filter cloth 2, a nonwoven fabric, a knitted fabric, or the like is used. And the material which is inferior to hot water permeability is used for the extraction bag 1, and the material which is excellent in hot water permeability is used for the filter cloth 2. FIG. In the present invention, the meaning of “inferior in hot water passage” or “excellent in hot water passage” is relative, and the hot water passage speed of the extraction bag 1 is slower than the hot water passage speed of the filter cloth 2. It is. The hot water passing speed is determined by the material and physical properties of the extraction bag 1 and the filter cloth 2. When both the extraction bag 1 and the filter cloth 2 are made of non-woven fabric, the hot water passing speed is generally determined by the following factors. (1) When the constituent fibers of the nonwoven fabric are hydrophilic, the hot water passing speed is increased, and when the non-woven fabric is hydrophobic, the hot water passing speed is decreased. (2) The hot water passing speed increases as the gap between the constituent fibers of the nonwoven fabric increases, and the hot water passing speed decreases as the gap decreases. (3) The hot water passing speed increases as the porosity of the nonwoven fabric increases, and the hot water passing speed decreases as the porosity decreases. (4) The thinner the nonwoven fabric is, the faster the hot water passing speed is; the thicker the nonwoven fabric is, the slower the hot water passing speed is. These factors are general factors, and the hot water supply speed varies depending on other factors. Therefore, by adjusting each of these factors, the extraction bag 1 adopts the one having a slow hot water passage speed (inferior in hot water passage property), and the filter cloth 2 has the one having a high hot water passage speed (in the hot water passage property). Adopt an excellent one.

抽出袋１及び濾過布２の材料して不織布を採用した場合、いずれも、熱可塑性繊維で形成されているのが好ましい。これは、抽出袋１及び濾過布２の各縁を熱融着によって封することができるからである。なお、熱融着の手段としては、加熱手段や超音波手段等の従来公知の手段を採用することができる。   When a nonwoven fabric is used as the material for the extraction bag 1 and the filter cloth 2, it is preferable that both are formed of thermoplastic fibers. This is because each edge of the extraction bag 1 and the filter cloth 2 can be sealed by heat sealing. Note that conventionally known means such as heating means and ultrasonic means can be employed as the means for heat fusion.

また、本発明は、前記した嗜好性飲料抽出バッグを作成するためのシートに関するものである。この嗜好性飲料抽出バッグ作成用シートは、略四辺形の通湯性に劣る抽出袋用シート１０の表面上部に支持シート４ａ及び４ｂが設けられてなるシート１０ａ及び１０ｂを、前記支持シート４ａ及び４ｂの上端が対向するようにして間隔を置いて配置し、前記シート１０ａ及び１０ｂの間隔を跨ぎ、前記抽出袋用シート１０の裏面に略四辺形の通湯性に優れる濾過布用シート２０が、その上縁が前記支持シート４ｂが設けられている位置に対応する位置で貼着され、その下縁が前記支持シート４ａが設けられている位置に対応する位置で貼着されている。なお、かかる嗜好性飲料抽出バッグ作成用シートは、一個づつ供給される場合もあり、また、左右に連続して複数個設けられた嗜好性飲料抽出バッグ作成用シート原反の形態で供給される場合もある。   Moreover, this invention relates to the sheet | seat for creating an above-described taste drink extraction bag. This palatable beverage extraction bag making sheet is formed by replacing the support sheets 4a and 10b with the support sheets 4a and 4b provided with support sheets 4a and 4b on the top surface of the extraction bag sheet 10 having a substantially quadrilateral inferior hot water permeability. 4b is disposed so as to be opposed to each other at the upper end, straddling the interval between the sheets 10a and 10b, and on the back surface of the extraction bag sheet 10, a filter cloth sheet 20 having a substantially quadrilateral hot water permeability is provided. The upper edge is attached at a position corresponding to the position where the support sheet 4b is provided, and the lower edge is attached at a position corresponding to the position where the support sheet 4a is provided. The palatable beverage extraction bag creation sheets may be supplied one by one, or in the form of a palatable beverage extraction bag creation sheet raw material that is provided in a plurality on the left and right sides. In some cases.

抽出袋用シート１０及び濾過布用シート２０の材料として不織布を採用した場合、いずれも、熱可塑性繊維で形成されているのが好ましい。かかる不織布を採用した嗜好性飲料抽出バッグ作成用シートを用いて、嗜好性飲料抽出バッグを製造する方法は、以下のとおりである。すなわち、嗜好性飲料抽出バッグ作成用シートの間隔を折り目線として、前記作成用シートの裏面が内面となるように二つ折りし、重合した抽出袋用シート１０及び濾過布用シート２０の左右縁を熱融着した後、重合したシート１０ａ及び１０ｂの下縁同士を開いて、嗜好性飲料被抽出物３を収納し、その後、前記下縁同士を熱融着して前記嗜好性飲料被抽出物３を密封することにより、嗜好性飲料抽出バッグを得ることができる。   When a nonwoven fabric is employed as the material for the extraction bag sheet 10 and the filter cloth sheet 20, it is preferable that both are formed of thermoplastic fibers. A method for producing a palatable beverage extraction bag using the palatable beverage extraction bag making sheet employing such a nonwoven fabric is as follows. That is, the left and right edges of the extracted extraction bag sheet 10 and the filter cloth sheet 20 are folded in half so that the back of the preparation sheet becomes the inner surface, with the interval between the taste beverage extraction bag preparation sheets as the crease line. After heat-sealing, the lower edges of the polymerized sheets 10a and 10b are opened to store the palatable beverage extract 3 and then the lower edges are heat-sealed to form the palatable beverage extract. By sealing 3, a palatable beverage extraction bag can be obtained.

本発明に係る嗜好性飲料抽出バッグは、略四辺形の通湯性の抽出袋１と、前記抽出袋１の内面に貼着され、前記抽出袋１の口を封する、前記抽出袋１よりも通湯性に優れる濾過布２と、前記抽出袋１及び前記濾過布２によって密封された嗜好性飲料被抽出物３と、前記抽出袋１の表面に設けられた支持シート４ａ及び４ｂとからなり、前記支持シート４ａ及び４ｂは、カップの縁に係合しうる引き起こし片５ａ及び５ｂを具備しており、前記引き起こし片５ａ及び５ｂをカップの縁に係合して、前記抽出袋１を開いて前記濾過布２へ注湯して抽出しうる構成とするとともに、前記濾過布２の、前記抽出袋１の内面への貼着部位６ａは、前記抽出袋１の内面で、前記支持シート４ａに対向する部分であって前記支持シート４ａの上縁以下の位置に貼着され、前記濾過布２の、前記抽出袋１の内面への貼着部位６ｂは、前記抽出袋１の内面で、前記支持シート４ｂに対向する部分であって前記支持シート４ｂの上縁以下の位置に貼着されたものである。
このため、この嗜好性飲料抽出バッグの支持シート４ａ及び４ｂから、引き起こし片５ａ及び５ｂを引き起こしてカップの縁に係合すると、抽出袋１が開き濾過布２が現れる。この濾過布２の上に湯を注ぐと、濾過布２は通湯性に優れるので、湯は速やかに濾過布２を通り、内部に浸入する。
しかるに、抽出袋１は、前記濾過布２よりも通湯性に劣るので、湯が抽出袋１内に留まり、こくのある風味のよいコーヒー等を淹れることができる。また、湯を注ぎすぎた場合、湯及び被抽出物３が抽出袋１の口から溢れ出そうとするが、被抽出物３は抽出袋１の口に貼着されている濾過布２によって塞き止められ、被抽出物３が濾過布２の外に溢れ出すことはない。
The palatable beverage extraction bag according to the present invention is a substantially quadrilateral hot water extraction bag 1 and the extraction bag 1 attached to the inner surface of the extraction bag 1 and sealing the mouth of the extraction bag 1. From the filter cloth 2 having excellent hot water permeability, the extraction bag 1 and the palatable beverage extract 3 sealed by the filter cloth 2, and the support sheets 4a and 4b provided on the surface of the extraction bag 1 The support sheets 4a and 4b are provided with raising pieces 5a and 5b that can be engaged with the edge of the cup. The raising pieces 5a and 5b are engaged with the edge of the cup so that the extraction bag 1 is formed. The structure is such that the filter cloth 2 can be extracted by pouring into the filter cloth 2, and the attachment site 6 a of the filter cloth 2 to the inner surface of the extraction bag 1 is the inner surface of the extraction bag 1. position of the upper edge below the support sheet 4a a portion facing to 4a Is adhered, the filter cloth 2, bonded portion 6b to the extraction bag 1 inner surface, the inner surface of the extraction bag 1, the upper edge of the support sheet 4b a portion facing the support sheet 4b It is affixed at the following positions .
For this reason, when the raising pieces 5a and 5b are raised from the support sheets 4a and 4b of the palatable beverage extraction bag and engaged with the edge of the cup, the extraction bag 1 opens and the filter cloth 2 appears. When hot water is poured onto the filter cloth 2, the filter cloth 2 is excellent in hot water permeability, so that the hot water quickly passes through the filter cloth 2 and enters the inside.
However, since the extraction bag 1 is inferior in hot water permeability than the filter cloth 2, the hot water stays in the extraction bag 1, and can be used to make rich coffee with good flavor. In addition, when hot water is poured excessively, the hot water and the extract 3 try to overflow from the mouth of the extraction bag 1, but the extract 3 is blocked by the filter cloth 2 attached to the mouth of the extraction bag 1. It is stopped, and the to-be-extracted material 3 does not overflow the filter cloth 2.

図２は本発明の一例に係る嗜好性飲料抽出バッグの表面図である。この抽出バッグは、通湯性に劣る抽出袋１の表面にカップの縁に係合しうる引き起こし片５ａを具備した支持シート４ａが設けられている。引き起こし片５ａを具備する支持シート４ａは、剛性のある紙等で形成されており、この構成は特許文献１に詳述されている。また、抽出袋１の裏面にも、同様に支持シート４ｂが設けられている。図３は、この嗜好性飲料抽出バッグの中央縦断面図である。嗜好性飲料被抽出物３は、抽出袋１の中に収納されており、抽出袋１の口は、通湯性に優れる濾過布２によって封されている。濾過布２の端部が、抽出袋１表面に設けられている支持シート４ａ及び４ｂに対応する内面の適宜の位置で貼着されることにより、封されている。貼着部位は６ａ及び６ｂで示されている。   FIG. 2 is a surface view of a palatable beverage extraction bag according to an example of the present invention. This extraction bag is provided with a support sheet 4a having a raising piece 5a which can be engaged with the edge of the cup on the surface of the extraction bag 1 which is inferior in hot water permeability. The support sheet 4a provided with the raising piece 5a is formed of rigid paper or the like, and this configuration is described in detail in Patent Document 1. Similarly, a support sheet 4b is provided on the back surface of the extraction bag 1 as well. FIG. 3 is a central longitudinal sectional view of this palatable beverage extraction bag. The palatable beverage extract 3 is stored in the extraction bag 1, and the mouth of the extraction bag 1 is sealed with a filter cloth 2 that has excellent hot water permeability. The end of the filter cloth 2 is sealed by being stuck at an appropriate position on the inner surface corresponding to the support sheets 4a and 4b provided on the surface of the extraction bag 1. The sticking sites are indicated by 6a and 6b.

この嗜好性飲料抽出バッグは、図４及び図１０に示した状態で使用される。すなわち、支持シート４ａ及び４ｂに具備されている引き起こし片５ａ及び５ｂを引き起こして、カップの縁に係合する。そうすると、抽出バッグの口（上部）が開くが、この口には濾過布２が張設されている。そして、この濾過布２の上方から湯を注ぐことによって、湯は抽出袋１及び濾過布２の内部に滞留し、被抽出物３と接して、コーヒー等が淹れられる。   This palatability drink extraction bag is used in the state shown in FIG.4 and FIG.10. That is, the raising pieces 5a and 5b provided on the support sheets 4a and 4b are caused to engage with the edge of the cup. Then, the mouth (upper part) of the extraction bag opens, and the filter cloth 2 is stretched over the mouth. Then, by pouring hot water from above the filter cloth 2, the hot water stays inside the extraction bag 1 and the filter cloth 2, comes into contact with the extraction object 3, and coffee is brewed.

本発明において、通湯性に劣る抽出袋１の材料としては不織布を用いるのが好ましく、特に、ポリプロピレン繊維又はポリエステル繊維等の熱可塑性繊維を構成繊維としたエンボスタイプの不織布を用いるのが、より好ましい。エンボスタイプの不織布は、構成繊維相互間が部分的に圧縮されると共に、圧縮部位で結合されてなるものであり、圧縮部位で構成繊維相互間の空隙が小さくなると共に空隙率が低くなっており、湯を通しにくくなっている。また、通湯性に優れる濾過布２の材料としては不織布を用いるのが好ましく、特に、ポリプロピレン繊維又はポリエステル繊維等の熱可塑性繊維を構成繊維としたスパンボンドタイプの薄手の不織布を用いるのが、より好ましい。薄手の不織布であり、相対的に湯を通しやすくなっている。   In the present invention, it is preferable to use a non-woven fabric as the material of the extraction bag 1 which is inferior in hot water permeability. In particular, it is more preferable to use an embossed type non-woven fabric composed of thermoplastic fibers such as polypropylene fibers or polyester fibers. preferable. The embossed type non-woven fabric is partly compressed between the constituent fibers and bonded at the compression site, and the porosity between the constituent fibers is reduced and the porosity is reduced at the compression site. It is difficult to pass hot water. Moreover, it is preferable to use a nonwoven fabric as a material of the filter cloth 2 excellent in hot water permeability, and in particular, it is preferable to use a spunbond type thin nonwoven fabric having thermoplastic fibers such as polypropylene fibers or polyester fibers as constituent fibers. More preferred. It is a thin non-woven fabric and relatively easy to pass hot water.

抽出袋１及び濾過布２の材料として、熱可塑性繊維を構成繊維とした不織布を用いた場合、抽出袋１の下縁及び左右縁は、この熱可塑性繊維を軟化又は溶融させて熱融着により貼着し、袋を形成するのが好ましい。また、抽出袋１の濾過布２の貼着部位６ａ及び６ｂも、熱可塑性繊維を軟化又は溶融させて熱融着により、貼着するのが好ましい。   When a nonwoven fabric made of thermoplastic fibers is used as the material for the extraction bag 1 and the filter cloth 2, the lower edge and the left and right edges of the extraction bag 1 are softened or melted by thermal fusion to soften or melt the thermoplastic fiber. It is preferable to stick and form a bag. Moreover, it is preferable that the sticking site | parts 6a and 6b of the filter cloth 2 of the extraction bag 1 are also stuck by softening or melting a thermoplastic fiber and heat-sealing.

図５は嗜好性飲料抽出バッグを作成するための作成シートの表面図であり、図６はその裏面図であり、図７はその側面図である。抽出袋１の表面を構成するのがシート１０ａであり、裏面を構成するのがシート１０ｂである。シート１０ａには抽出袋用シート１０の表面に支持シート４ａが設けられており、シート１０ｂには抽出袋用シート１０の表面に支持シート４ｂが設けられている。シート１０ａとシート１０ｂは、支持シート４ａ及び４ｂの上端が対向するようにして間隔を置いて配置され、濾過布用シート２０の幅方向中心線に対して、線対称となるように配置されている。そして、シート１０ａ及び１０ｂは、その裏面において、濾過布用シート２０の下縁及び上縁と貼着部位６ａ及び６ｂで貼着され、一体化されている。すなわち、間隔を置いて配置されているシート１０ａ及び１０ｂを跨いで、濾過布用シート２０が配置され貼着されている。貼着部位６ａはシート１０ａの支持シート４ａに対応する裏面に位置しており、貼着部位６ｂはシート１０ｂの支持シート４ｂに対応する裏面に位置している。また、貼着部位６ａは濾過布用シート２０の下縁が貼着されており、貼着部位６ｂは濾過布用シート２０の上縁が貼着されている。   FIG. 5 is a front view of a creation sheet for creating a palatable beverage extraction bag, FIG. 6 is a back view thereof, and FIG. 7 is a side view thereof. The sheet 10a constitutes the surface of the extraction bag 1, and the sheet 10b constitutes the back surface. The sheet 10 a is provided with a support sheet 4 a on the surface of the extraction bag sheet 10, and the sheet 10 b is provided with a support sheet 4 b on the surface of the extraction bag sheet 10. The sheet 10a and the sheet 10b are arranged at an interval so that the upper ends of the support sheets 4a and 4b face each other, and are arranged so as to be line-symmetric with respect to the center line in the width direction of the filter cloth sheet 20. Yes. And the sheet | seats 10a and 10b are stuck by the lower edge and upper edge of the sheet | seat 20 for filter cloths, and the sticking site | parts 6a and 6b in the back surface, and are integrated. That is, the filter cloth sheet 20 is disposed and stuck across the sheets 10a and 10b disposed at intervals. The sticking part 6a is located on the back surface corresponding to the support sheet 4a of the sheet 10a, and the sticking part 6b is located on the back surface corresponding to the support sheet 4b of the sheet 10b. Moreover, the lower edge of the filter cloth sheet 20 is stuck to the sticking part 6a, and the upper edge of the filter cloth sheet 20 is stuck to the sticking part 6b.

抽出袋用シート１０及び濾過布用シート２０は、抽出バッグが形成された後は、各々、抽出袋１及び濾過布２となるものである。したがって、抽出袋用シート１０は通湯性に劣る不織布で構成され、濾過布用シート２０は通湯性に優れる不織布で構成されているのが好ましい。そして、いずれの不織布も熱可塑性繊維を構成繊維とするのが、より好ましい。抽出袋用シート１０及び濾過布用シート２０として、いずれも熱可塑性繊維を構成繊維とする不織布を用いた場合、貼着部位６ａ及び６ｂは、熱可塑性繊維の軟化又は溶融による熱融着によって、貼着されているのが好ましい。   The extraction bag sheet 10 and the filter cloth sheet 20 become the extraction bag 1 and the filter cloth 2, respectively, after the extraction bag is formed. Therefore, it is preferable that the extraction bag sheet 10 is composed of a non-woven fabric with poor hot water permeability, and the filter cloth sheet 20 is composed of a non-woven fabric with excellent hot water permeability. And it is more preferable for any nonwoven fabric to use thermoplastic fibers as constituent fibers. When both the extraction bag sheet 10 and the filter cloth sheet 20 are nonwoven fabrics comprising thermoplastic fibers as the constituent fibers, the pasting sites 6a and 6b are obtained by thermal fusion by softening or melting the thermoplastic fibers. It is preferable that it is stuck.

嗜好性飲料抽出バッグ作成用シートは、図５乃至図７に示した一個づつの形態で抽出バッグ作成者に供給してもよいが、作成用シートが左右に連続して複数個設けられ巻物となった作成用シート原反の形態で供給してもよい。図８及び図９は、作成用シート原反の一部を示した表面図及び裏面図である。かかる作成用シート原反は、抽出バッグ作成者によって、一個づつの形態に切断されて抽出バッグが作成される。   The palatable beverage extraction bag creation sheet may be supplied to the extraction bag creator in the form of one by one shown in FIG. 5 to FIG. You may supply with the form of the produced sheet raw material. 8 and 9 are a front view and a back view showing a part of the original sheet for production. Such an original sheet for production is cut into individual forms by an extraction bag creator to create an extraction bag.

抽出袋用シート１０及び濾過布用シート２０として、いずれも熱可塑性繊維を構成繊維とする不織布を用いた作成用シートの場合、以下のようにして抽出バッグが製造される。まず、濾過布用シート２０の幅方向中心線に対して線対称に配置されているシート１０ａ及び１０ｂを、シート１０ａ及び１０ｂの裏面が内面となるように、前記中心線を折り目線として二つ折りし、シート１０ａ及び１０ｂを重合する。そして、重合した抽出袋用シート１０及び濾過布用シート２０の左右縁を熱融着する。そうすると、重合したシート１０ａ及び１０ｂの下縁同士が開口している袋が形成される。そこで、この開口から嗜好性飲料被抽出物３を収納した後、シート１０ａ及び１０ｂの下縁同士を熱融着する。以上の方法で、被抽出物３が密封された嗜好性飲料抽出バッグが得られるのである。   As the extraction bag sheet 10 and the filter cloth sheet 20, in the case of a production sheet using a nonwoven fabric having thermoplastic fibers as constituent fibers, an extraction bag is manufactured as follows. First, the sheets 10a and 10b arranged symmetrically with respect to the center line in the width direction of the filter cloth sheet 20 are folded in half with the center line as a crease line so that the back surfaces of the sheets 10a and 10b become the inner surface. Then, the sheets 10a and 10b are polymerized. Then, the right and left edges of the polymerized extraction bag sheet 10 and the filter cloth sheet 20 are heat-sealed. Then, a bag is formed in which the lower edges of the polymerized sheets 10a and 10b are open. Therefore, after storing the palatable beverage extract 3 from this opening, the lower edges of the sheets 10a and 10b are heat-sealed. By the above method, the palatable beverage extraction bag in which the extract 3 is sealed is obtained.
