Description

本発明はコーヒー及び紅茶、煎茶、ウーロン茶その他健康茶等お茶類の抽出用バッグに関するものである。更に詳しく述べると、バッグの把手を引き起こすと接続部及び把手が、それぞれ把手保持部及び接続部に対してくの字状に伸びる機能を有する。更に把手の切込み部分にカップの縁を挿入する時、切込み部分の両側に設けられた、鰭の作用によりカップへのフィット性が高められたコーヒー等の抽出用バッグである。このため広範囲のサイズ及び形状のカップに適用した場合にも安定した抽出性を有する。 The present invention relates to a bag for extracting tea such as coffee and black tea, sencha, oolong tea and other health teas. More specifically, when the handle of the bag is caused, the connecting portion and the handle have a function of extending in a dogleg shape with respect to the handle holding portion and the connecting portion, respectively. Furthermore, when inserting the edge of a cup into the notch part of a handle, it is an extraction bag for coffee or the like, which is provided on both sides of the notch part and has an improved fit to the cup by the action of a ridge. For this reason, even when applied to a wide range of cup sizes and shapes, it has a stable extractability.

従来からコーヒーの抽出方法はドリップ方式が多く、最近はペーパー・ドリップ方式が最も広範囲に使用される様になっている。しかしながら、微粒子や油脂の漏出等抽出性の他取扱上にも尚多くの問題点があり、これらの点を改善するためバッグの形状や材質についても多くの試みが開示されている。 Conventionally, there are many drip methods for extracting coffee, and recently, the paper drip method is most widely used. However, there are still many problems in handling in addition to extractability such as leakage of fine particles and fats and oils, and many attempts have been disclosed for the shape and material of the bag in order to improve these points.

例えば、実開昭55-123480 号公報にはフィルターに把手を付け、カップ等の縁に掛けて抽出できる形状のフィルターが開示され、また特開平3-210214号及び3-218711号公報、実開平 7-223号公報にはフィルター側面に、切れ込みがある把手を設け、長時間カップの縁に掛けたままで抽出出来るフィルターが開示されている。更に、特開平 6-315435 号公報にはフィルター側面に切れ込みがある把手及び補助用の小把手を設けて、フィルターをカップの縁にかけて保持する時の安定性を高める方式が開示されている。しかし、フィルターの上部からお湯を注入する方式で使用する場合には、フィルター内部のコーヒー粒子等のろ過層の厚さを均一にすること及び充分な安定性の確保については尚問題があった。 For example, Japanese Utility Model Laid-Open No. 55-123480 discloses a filter having a shape that can be extracted by attaching a handle to a filter and hung it on the edge of a cup or the like, and Japanese Patent Laid-Open Nos. 3-210214 and 3-218711. JP-A-7-223 discloses a filter that can be extracted while being provided on the side of the cup for a long time by providing a handle with a notch on the side of the filter. Further, JP-A-6-315435 discloses a method for improving stability when a filter is held on the edge of a cup by providing a handle having a notch on the side of the filter and an auxiliary handle. However, when using the method in which hot water is injected from the upper part of the filter, there is still a problem in making the thickness of the filtration layer such as coffee particles inside the filter uniform and ensuring sufficient stability.

最近プラスチックまたは厚紙の複雑なバッグ保持機構を付加したバッグで、使用時バッグのほぼ全体がカップ上部の縁の上に載せられ、抽出性も優れ且つ安定性も高められたコーヒーバッグが急速に普及している。しかし、これらは構造が複雑で高価であり、またディスポーザブルの日用品としては環境保護の観点からも問題が指摘されている。またコーヒーの他、紅茶、煎茶、ウーロン茶、健康茶等お茶類の抽出用に使用する場合も種々な点で改善の余地が残されている。

However, these have complicated structures and are expensive, and problems have been pointed out from the viewpoint of environmental protection as disposable daily necessities. In addition to coffee, there is still room for improvement in various points when used for extraction of teas such as black tea, sencha, oolong tea, and health tea.
Japanese Utility Model Publication No.55-123480 Japanese Patent Laid-Open No. 3-210214 JP-A-3-218711 Japanese Utility Model Publication No.7-223 JP-A-6-315435

これらの抽出用バッグの問題点にかんがみ、コーヒー、紅茶、煎茶等お茶類を抽出する場合、バッグの側面に取り付けた把手、補助用の小把手の構造及び機能を更に工夫することによって、より広範囲なカップのサイズ及び形状を有する場合にも、抽出用バッグのカップへのフィット性を高めると共に、抽出時にバッグの開口を最大の状態に保持し、抽出時にバッグの位置及び形状を最適に保持できる、抽出用バッグを開発して提供しようとするものである。 In view of the problems of these extraction bags, when extracting teas such as coffee, tea, sencha, etc., by further devising the structure and function of the handle attached to the side of the bag and auxiliary handle, a wider range Even when the cup has a large cup size and shape, it improves the fit of the extraction bag to the cup and keeps the opening of the bag in the maximum state during extraction, so that the position and shape of the bag can be optimally maintained during extraction. It is intended to develop and provide an extraction bag.

コーヒー、紅茶等のカップの形状は広範囲にわたっている。特に上端開口部のサイズが広範囲にわたる場合と、口縁部の垂直断面が種々な形状を有する場合への適用性を高める必要がある。上端開口部のサイズの大小に対しては、従来抽出用バッグは把手保持部と把手との２つの部分から構成されていたが、把手保持部と把手との間にミシン目を介して接続された接続部を挿入することによって、解決可能となる。抽出用バッグをこのような構造とすれば、把手を引き起こすと把手と把手保持部との間に、接続部を介して図３に示すように、２つの「くの字」形に伸びた構造が形成される。このため、抽出用バッグとカップの口縁部との間隔の大小に拘わらず、バッグの変形等の影響を受けることなく取り付けることが可能となる。 Cups such as coffee and tea have a wide range of shapes. In particular, it is necessary to increase the applicability when the size of the upper end opening is wide and when the vertical cross section of the mouth edge has various shapes. For the size of the upper end opening, the conventional extraction bag is composed of two parts, a handle holding part and a handle, but is connected through a perforation between the handle holding part and the handle. This can be solved by inserting the connected portion. If the extraction bag has such a structure, when the handle is raised, a structure extending between the handle and the handle holding portion and extending in two “shapes” via the connecting portion as shown in FIG. Is formed. For this reason, regardless of the size of the gap between the extraction bag and the mouth edge of the cup, the bag can be attached without being affected by the deformation of the bag.

更に把手は従来は抽出用バッグを開口させる時の「つまみ」との意識が強いため、カップの口縁部が挿入される切込み線と付け根のミシン目との間隔が狭く設けられていた。その間隔を広げることによってカップの内径の大小への適応性を一層高めることが可能となった。 Furthermore, since the handle has a strong awareness of the “knob” when the extraction bag is opened, the gap between the cut line into which the lip of the cup is inserted and the perforation at the base is narrowly provided. By widening the interval, the adaptability to the size of the inner diameter of the cup can be further enhanced.

カップの口縁部の断面は非常に多くの形状にわたっている。特に口縁部が外側へ大きく開いている場合には、抽出用バッグを取り付ける把手の切込み線の傾斜が、口縁部断面口の開く傾斜とかなり相違がある場合には、切込み線が歪んだ形となって、切込み線と口縁部との間にかなりの隙間ができる。この影響を受けて抽出用バッグが変形するため、抽出時にバッグの位置及び形状を最適に保持することができない。これを改善するため把手の切込み線の両側には屈曲可能なミシンを介して、それぞれ一対の鰭(7) 、(7) ′及び(8) 、(8) ′を設けた。更に、接続部がカップの内面に接触する部分にも、鰭(11)、(11)′を設けた。これらの付加された構造部分によって、図３に示すようにカップの口縁部が外側へ大きく開いている場合にも、抽出用バッグの位置及び形状を常に最適な状態に保持することができることを見出した。 The cross-section of the lip of the cup spans many shapes. Especially when the mouth edge is wide open to the outside, if the inclination of the cut line of the handle to which the extraction bag is attached is considerably different from the inclination of the mouth edge cross-section mouth, the cut line is distorted. Due to the shape, there is a considerable gap between the score line and the mouth edge. Since the extraction bag is deformed under this influence, the position and shape of the bag cannot be optimally maintained during extraction. In order to improve this, a pair of scissors (7), (7) 'and (8), (8)' are provided on both sides of the handle cut line via bendable sewing machines, respectively. Furthermore, the hooks (11) and (11) 'are also provided in the portion where the connecting portion contacts the inner surface of the cup. With these added structural parts, the position and shape of the extraction bag can always be kept in an optimal state even when the mouth edge of the cup is wide open outward as shown in FIG. I found it.

更に本発明に付加した、把手保持部の一部と抽出用バッグとの未接着部分、接続部の抉り(10)、(10)′はカップの口縁部に掛けて、抽出用バッグを最も良好な状態に保持する機能を有するものであり、更にミシン目(12)、(12)′及び(13)、(13)′は接続部のカップ内面に接触する部分の変形を容易にすることによって、抽出用バッグを最大限に開口した形状である、正方形〜円形に保持する機能を有することも見出した。これらの知見に基づいて本発明に到達した。 Further, the unattached portion between the grip holding portion and the extraction bag, and the connection portion ridges (10) and (10) ' added to the present invention are hung on the mouth edge of the cup, and the extraction bag is It has a function to keep it in good condition, and the perforations (12), (12) 'and (13), (13)' make it easy to deform the part of the connecting part that contacts the cup inner surface. It has also been found that it has a function of holding the extraction bag in a square to circular shape, which is a shape with the maximum opening. The present invention has been reached based on these findings.

Furthermore, in the present invention, a roll-shaped filter sheet folded flat is fused at regular intervals, and then wound up with a roll to be filled with a certain amount of coffee or as an extraction empty bag. Also included are bags for coffee or tea extraction for the raw material for bag processing.

本発明の抽出用バッグはコーヒー、紅茶等お茶類の抽出に使用するものであるが、これらのカップの形状やサイズは広範囲にわたっている。抽出用バッグとカップの口縁部との接続部分の構造を、把手保持部と把手との間にミシン目を介して接続された接続部を挿入することによって、抽出用バッグとカップの口縁部との間隔の大小に拘わらず、バッグの変形等の影響を及ぼすことなく取り付けることが可能となる。更に、抽出用バッグの把手の切込み線の両側には屈曲可能なミシン目を介して、それぞれ一対の鰭を設けた。更に、接続部がカップの内面に接触する部分にも、鰭(11)、(11)′を設けた。これらの構造部分によって、カップの口縁部が外側へ大きく開いている場合にも、抽出用バッグの位置及び形状を常に最適な状態に保持することができる。 The extraction bag of the present invention is used for extraction of teas such as coffee and tea, but the shapes and sizes of these cups are wide-ranging. The structure of the connection part between the extraction bag and the lip of the cup is inserted into the lip of the extraction bag and the cup by inserting a connection part connected through a perforation between the handle holding part and the handle. The bag can be attached without being affected by deformation of the bag regardless of the distance from the portion. Furthermore, a pair of ridges were provided on both sides of the cut line of the handle of the extraction bag via a bendable perforation. Furthermore, the hooks (11) and (11) 'are also provided in the portion where the connecting portion contacts the inner surface of the cup. With these structural portions, the position and shape of the extraction bag can always be kept in an optimum state even when the mouth edge of the cup is greatly opened outward.

本発明の抽出用バッグに使用される原料はコーヒー粒子及び紅茶、煎茶、ウーロン茶、健康茶の他、麦茶、昆布茶等のお茶類が広く含まれている。 In addition to coffee particles and black tea, sencha, oolong tea, health tea, tea materials such as barley tea and kelp tea are widely included as raw materials used in the extraction bag of the present invention.

本発明の抽出用バッグは、濾過性を有する柔軟なシートでつくられたものである必要があり、その素材は特に限定せず織物、編み物、不織布、紙或いはこれらの複合材料ならば広く使用出来る。バッグの材質や組織によりろ過性には微妙な相違があり、得られた嗜好性飲料の風味に影響することがある。例えば、香りやコク味が優れたコーヒーをいれるために、フィルターに要求される最も重要な性質は、コーヒーの微粒子が液中に漏れ出さないことである。更にコーヒー液中に含まれている油脂を吸着除去して、カップの表面に油膜が浮かない様にすることが必要である。これらはいずれもコーヒーの味を著しく阻害する要素で、微粒子が混入すれば舌触りが悪く感じられ、またカップの表面に油脂が浮くとギラギラ光るため好まれない。 The extraction bag of the present invention needs to be made of a flexible sheet having filterability, and the material is not particularly limited and can be widely used if it is a woven fabric, knitted fabric, non-woven fabric, paper or a composite material thereof. . There are subtle differences in filterability depending on the material and structure of the bag, which may affect the flavor of the resulting palatability beverage. For example, the most important property required for a filter in order to make coffee with a good aroma and richness is that fine particles of coffee do not leak into the liquid. Further, it is necessary to absorb and remove the oil and fat contained in the coffee liquid so that the oil film does not float on the surface of the cup. All of these are factors that significantly impair the taste of coffee. If fine particles are mixed in, it feels bad to the touch, and if oil or fat floats on the surface of the cup, it is not preferred.

本発明に使用するコーヒー等の抽出用バッグの素材は特に限定せず前記の様に広範囲のフィルタークロスが使用出来るが、微粒子の漏出防止及び油脂の吸着性を高める素材として、繊度が約 0.2デニール以下の超極細繊維を含む不織布が知られている。従って、本発明のバッグにはこの様な素材が好ましい。超極細繊維は例えば、メルトブロー法により熱可塑性ポリマーから製造することができる。熱可塑性ポリマーの種類としては、ポリプロピレン、ポリエチレン等がある。またこの様な超極細繊維の不織布層と、通常の太さの繊維からなる支持層の複合不織布を使用することにより、ろ過性及びろ布の機械的性質を一層向上させることが出来る。 The material of the extraction bag such as coffee used in the present invention is not particularly limited, and a wide range of filter cloths can be used as described above. Nonwoven fabrics containing the following ultrafine fibers are known. Therefore, such a material is preferable for the bag of the present invention. The ultrafine fibers can be produced from, for example, a thermoplastic polymer by a melt blow method. Examples of the thermoplastic polymer include polypropylene and polyethylene. Further, by using such a nonwoven fabric layer of super extra fine fibers and a composite nonwoven fabric of a support layer made of fibers having a normal thickness, the filterability and the mechanical properties of the filter fabric can be further improved.

バッグ本体(1) の形状は図１に示す様に長方形で、従来から一般に使用されている様にコーヒー粒子、紅茶等を内部に封入してお湯に浸漬し或いはお湯を注いで使用することもできる。尚、特に長方形に限定する必要はなく正方形でも勿論使用可能である。最近コーヒー粒子を封入したバッグにプラスチックまたは厚紙の複雑なバッグ保持機構を付加した方式も使用されている。抽出時バッグをカップの上に保持してバッグの下端と抽出液がたまるカップの液面が接触することがなく、常に抽出液がバッグの下端から滴下する様にして使用されている。 The shape of the bag body (1) is rectangular as shown in Fig. 1, and it is also possible to enclose coffee particles, tea, etc. inside and immerse them in hot water or pour hot water as is generally used. it can. In addition, it is not necessary to limit to a rectangle in particular, and a square can of course be used. Recently, a method in which a complicated bag holding mechanism of plastic or cardboard is added to a bag enclosing coffee particles is also used. During extraction, the bag is held on the cup so that the lower end of the bag does not come into contact with the liquid level of the cup where the extract is collected, and the extract is always dripped from the lower end of the bag.

また、把手保持部及び把手は腰があるシートで作られたものが好ましい。「腰がある」とは、例えばケント紙のようにある程度の剛性と弾性と共に、変形させた時その形状に保持できる性質を有するシートである。少し厚みがある紙或いはプラスチックシート等である。また、把手保持部は通常はお湯に浸漬された状態で使用されるため、耐水性を有する材質が好ましい。 Further, the handle holding part and the handle are preferably made of a seat with a waist. “Having a waist” is a sheet that has a certain degree of rigidity and elasticity, such as Kent paper, and has the property of being held in its shape when deformed. Paper or plastic sheet with a little thickness. Moreover, since the handle holding part is normally used in the state immersed in hot water, the material which has water resistance is preferable.

従来抽出用バッグは把手保持部と把手との２つの部分から構成されていたが、本発明においては、把手保持部と把手との間にミシン目を介して接続された接続部が挿入されている。このため把手を引き起こすと把手と把手保持部との間に、接続部を介して、２つの「くの字」形に伸びた構造が形成される。このため、抽出用バッグとカップの口縁部との間隔の大小に拘わらず、バッグの変形等の影響を受けることなく取り付けることが可能となる。 Conventionally, an extraction bag is composed of two parts, a handle holding part and a handle, but in the present invention, a connecting part connected through a perforation is inserted between the handle holding part and the handle. Yes. For this reason, when the handle is caused, a structure extending in two “shapes” is formed between the handle and the handle holding portion via the connecting portion. For this reason, regardless of the size of the gap between the extraction bag and the mouth edge of the cup, the bag can be attached without being affected by the deformation of the bag.

本発明の抽出用バッグは内容物を封入した後上端をシールし、使用時開口してその部分からお湯を注入して使用することも出来るし、或いは開口状態のバッグに使用時適宜コーヒー粒子等内容物を入れ、上からお湯を注入して使用することも出来る。以下、実施例を挙げて本発明を更に具体的に説明する。 The extraction bag of the present invention can be used by sealing the upper end after filling the contents, opening it when in use and pouring hot water from that part, or appropriately using coffee particles etc. when using the bag in the open state The contents can be put in and hot water can be poured from above. Hereinafter, the present invention will be described more specifically with reference to examples.

図１に本発明のコーヒーまたはお茶類抽出用バッグの一態様の正面図を示す。抽出用バッグ(1) はバッグ本体(2) と把手保持部(3) 、(3) ′からなっている。抽出用バッグ本体(2) の正面形状は縦長の長方形で、２層の不織布積層体よりなっている。また、バッグの容量を大きくするため両サイドにギャザーが入った態様のバッグも使用できる。把手保持部(3) 、(3) ′はバッグの表裏両面の対称的な位置に取り付けられ、その内部には屈曲可能なミシン目を介して接続部(4) 、(4) ′が、更に同様な屈曲可能なミシン目を介して把手(5) 、(5) ′が設けられている。その材質は総て耐水性があり腰がある厚めの紙からなっている。把手保持部(3) 、(3) ′の部分はヒートプレスでバッグの表面に融着されているが、その内部に設けられミシン目を介して接続されている、接続部(4) 、(4) ′及び把手(5) 、(5) ′は、バッグ表面には融着されていない。 FIG. 1 shows a front view of one embodiment of a coffee or tea extraction bag of the present invention. The extraction bag (1) is composed of a bag body (2) and handle holding portions (3) and (3) ′. The front shape of the extraction bag body (2) is a vertically long rectangle, which is a two-layer nonwoven fabric laminate. Moreover, in order to enlarge the capacity | capacitance of a bag, the bag of the aspect which entered the gathers in both sides can also be used. The grip holders (3) and (3) 'are attached to symmetrical positions on both the front and back sides of the bag, and inside thereof there are connecting parts (4) and (4)' through bendable perforations. Handles (5), (5) 'are provided through similar bendable perforations. The material is all made of thick paper with water resistance and waist. The grip holders (3) and (3) ′ are fused to the surface of the bag with a heat press, but are connected to each other through the perforations provided inside the connection parts (4) and (4). 4) 'and the handles (5) and (5)' are not fused to the bag surface.

把手(5) 、(5) ′の内部には下方が開いた切込み(6) 、(6) ′が設けられ、切込みの両側には屈曲可能なミシン目を介して、切込み(6) 、(6) ′に対して左右ほぼ対称的な形状の鰭(6) 、(6) ′及び、(7) 、(7) ′が設けられている。これらの鰭はミシン目を介して把手に屈曲可能に接続されているため、カップの口縁部の断面形状と、把手の切込み(6) 、(6) ′の傾斜とが或る程度差異がある場合でも、これらの鰭の弾力性によって充分にフィットして、安定した状態にカップ上に保持できる機能を有する。 The handles (5), (5) 'are provided with incisions (6), (6)' open at the bottom, and the notches (6), ( 'fin almost symmetrical shape lateral relative (6), (6)' 6) and (7), is provided with (7) '. Since these hooks are connected to the handle via the perforation so that they can be bent, there is some difference between the cross-sectional shape of the lip of the cup and the inclination of the notches (6) and (6) '. Even in some cases, it has a function that can be sufficiently fitted by the elasticity of these heels and held on the cup in a stable state.

抽出用バッグの使用時、把手(5) 、(5) ′を指先でつまんで引き起こすと、接続部(4) 、(4) ′及び把手(5) 、(5) ′がそれぞれ把手保持部及び接続部に対してくの字状に折れ曲がって伸びる。このため切込み(6) 、(6) ′にカップの縁を挿入する時、鰭(6) 、(6) ′及び(7) 、(7) ′の屈曲性と相まって、カップへのフィット性が高められ、抽出用バッグの開口部は正方形ないしほぼ円形に大きく開口され、カップ上に安定した状態に保持される。 When using the extraction bag, if the handle (5), (5) 'is picked up with the fingertip, the connection (4), (4)' and the handle (5), (5) ' It bends and extends in a U shape against the connection. For this reason, when inserting the edge of the cup into the notches (6) and (6) ', the fitting property to the cup is combined with the flexibility of 鰭 (6), (6)' and (7), (7) '. The opening of the extraction bag is greatly opened in a square or almost circular shape, and is kept stable on the cup.

この際、把手(5) 、(5) ′及び接続部(4) 、(4) ′は、前述のようにそれぞれ屈曲可能なミシン目を介して、くの字状に折れ曲がって伸び、または縮むことも可能なため、カップ口縁部の口径が相当変動しても、抽出用バッグは容易にフィットするため、適用可能となる特徴を有する。抽出用バッグの内部に粉末状または粒状のコーヒーを挿入し、熱湯を注入すればバッグ内で抽出されたコーヒー液が、バッグで濾過されてカップ内に滴下して飲料が調整される。 At this time, the grips (5) and (5) ′ and the connecting portions (4) and (4) ′ are bent and stretched or contracted in a dogleg shape through the bendable perforation as described above. Therefore, even if the diameter of the cup mouth edge varies considerably, the extraction bag fits easily and thus has a feature that can be applied. If powdered or granular coffee is inserted into the extraction bag and hot water is poured, the coffee liquid extracted in the bag is filtered by the bag and dropped into the cup to prepare a beverage.

図２に本発明のコーヒーまたはお茶類抽出用バッグの一態様の正面図を、図３にこの抽出用バッグをコーヒーカップに装着した場合の斜視図を示す。抽出用バッグ(1) はバッグ本体(2) と把手保持部(3) 、(3) ′からなっている。抽出用バッグ本体(2) の正面形状は縦長の長方形で、２層の不織布積層体よりなっている。把手保持部(3) 、(3) ′はバッグの表裏両面の対称的な位置に取り付けられ、その内部には屈曲可能なミシン目を介して接続部(4) 、(4) ′が、更に同様な屈曲可能なミシン目を介して把手(5) 、(5) ′が設けられている。その材質は総て耐水性があり腰がある厚めの紙からなっている。 FIG. 2 shows a front view of one embodiment of the coffee or tea extraction bag of the present invention, and FIG. 3 shows a perspective view when the extraction bag is attached to a coffee cup. The extraction bag (1) is composed of a bag body (2) and handle holding portions (3) and (3) ′. The front shape of the extraction bag body (2) is a vertically long rectangle, which is a two-layer nonwoven fabric laminate. The grip holders (3) and (3) 'are attached to symmetrical positions on both the front and back sides of the bag, and inside thereof there are connecting parts (4) and (4)' through bendable perforations. Handles (5), (5) 'are provided through similar bendable perforations. The material is all made of thick paper with water resistance and waist.

把手保持部(3) 、(3) ′の部分はヒートプレスでバッグの表面に融着されているが、その内部に設けられたミシン目を介して接続されている、接続部(4) 、(4) ′及び把手(5) 、(5) ′は、バッグ表面には融着されていない。但し把手保持部(3) 、(3) ′の一部、(9) 、(9) ′は抽出用バッグ(1) と未接着状態に保持されている。これは使用時にバッグを最大限に拡張せるための構造の一部である。接続部(4) 、(4) ′には抉り(10)、(10)′及びミシン目を介して鰭(11)、(11)′、ミシン目(12)、(12)′及び(13)、(13)′が設けられている。 The grip holders (3), (3) 'are fused to the surface of the bag with a heat press, but are connected through perforations provided in the interior, the connecting parts (4), (4) 'and the handles (5) and (5)' are not fused to the bag surface. However, a part of the handle holding portions (3) and (3) ′, (9) and (9) ′ are held in an unbonded state with the extraction bag (1). This is part of the structure for maximum expansion of the bag in use. The connecting parts (4), (4) 'are connected to the ridges (11), (11)', perforations (12), (12) 'and (13 ), (13) ′.

これらの鰭やミシン目は抽出用バッグの使用時に接続部(4) 、(4) ′がカップの内面に接触する部分となるため、抉り(10)、(10)′はカップの口縁部に嵌め合わされて、抽出用バッグの姿勢の安定性を高め、その他の鰭やミシン目はその弾力性によって抽出用バッグとカップのフィット性が高められる。このため使用時に生ずる把手保持部及び接続部の歪みを遮断して、バッグを最大限に拡張した状態でカップ上に保持する機能を有する。 Since these ridges and perforations are the parts where the connecting parts (4), (4) 'come into contact with the inner surface of the cup when the extraction bag is used, the ridges (10), (10)' And the stability of the posture of the extraction bag is enhanced, and the fit of the extraction bag and the cup is enhanced by the elasticity of other folds and perforations.

Since these hooks are connected to the handle via the perforation so that they can be bent, there is some difference between the cross-sectional shape of the lip of the cup and the inclination of the notches (6) and (6) '. Even in some cases, it has a function that can be sufficiently fitted by the elasticity of these heels and held on the cup in a stable state. The functions of these wrinkles and perforations are apparent from the perspective view shown in FIG.

抽出用バッグの使用時、把手(5) 、(5) ′を指先でつまんで引き起こすと、接続部(4) 、(4) ′及び把手(5) 、(5) ′がそれぞれ把手保持部及び接続部に対してくの字状に折れ曲がって伸びる。このため切込み(6) 、(6) ′にカップの縁を挿入する時、鰭(6) 、(6) ′及び(7) 、(7) ′によりカップへのフィット性が高められ、抽出用バッグの開口部は正方形ないしほぼ円形に大きく開口され、カップ上に安定した状態に保持される。 When using the extraction bag, if the handle (5), (5) 'is pinched with a fingertip, the connection (4), (4)' and the handle (5), (5) ' It bends and extends in a U shape with respect to the connection part. For this reason, when inserting the edge of the cup into the notches (6), (6) ', the fit to the cup is enhanced by the ridges (6), (6)' and (7), (7) '. The opening of the bag is greatly opened in a square or almost circular shape, and is held in a stable state on the cup.

この際、把手(5) 、(5) ′及び接続部(4) 、(4) ′は、前述のようにそれぞれ屈曲可能なミシン目を介して、くの字状に折れ曲がって伸び、または縮むことも可能なため、カップ口縁部の口径が相当変動しても、抽出用バッグは容易にフィットするため、適用可能となる点が本発明の最も大きな特徴である。 At this time, the grips (5) and (5) ′ and the connecting portions (4) and (4) ′ are bent and stretched or contracted in a dogleg shape through the bendable perforation as described above. Since the extraction bag fits easily even if the caliber of the cup lip is considerably fluctuating, the most significant feature of the present invention is that it can be applied.
