Description

本発明はコーヒーの他、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、バッグの把手の先端部を引き起こすと先端部と中間部が、それぞれ中間部及び把手保持部対して２重のＶ字状に伸縮できる構造を有する。このため広範なサイズ及び形状のカップに密着させることが可能となる。これにより、抽出用バッグの保持性及び抽出性を高めるように構成された嗜好性飲料抽出用バッグである。   The present invention relates to a bag for extracting tea such as tea, sencha, oolong tea and other health teas in addition to coffee. More specifically, when the leading end portion of the handle of the bag is raised, the leading end portion and the intermediate portion can be expanded and contracted in a double V shape with respect to the intermediate portion and the handle holding portion, respectively. For this reason, it becomes possible to make it contact | adhere to the cup of a wide size and shape. Thereby, it is a taste drink extraction bag comprised so that the holding | maintenance property and extraction property of an extraction bag might be improved.

近年コーヒーをペーパーフィルターによるドリップ方式で入れて飲む習慣が一般的となり、抽出時フィルターをカップ上に安定した状態に保持すると共に、コーヒー等の抽出性を高めるための支持具も使用される様になっている。この目的で開発された支持具も既に幾つか開示されている。しかし尚、抽出時の安定性や微粒子・油脂の漏出等取扱上にも多くの問題点が残されている。   In recent years, it has become common practice to drink coffee using a paper filter drip method, and while holding the filter in a stable state on the cup, a support tool for enhancing the extractability of coffee etc. is also used. It has become. Several supports that have been developed for this purpose have already been disclosed. However, many problems still remain in handling such as stability during extraction and leakage of fine particles and fats and oils.

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

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た方式が開示されている。 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. Furthermore,
Japanese Patent No. 6-315435 discloses a method in which a handle having a notch on the side of the filter and an auxiliary handle are provided to improve stability when the filter is held on the edge of the cup.

更に特開平10-85136号公報には、嗜好性飲料抽出用バッグ及びバッグをカップ上に保持するための紙製支持具からなる支持具付バッグを使用する時、表裏のシートの間隔を拡げバッグを開口させてカップ上に乗せる際、支持具の下部に設けられた４ケ所の切片の下端がカップの縁と接触する部分に打抜部分を設け、カップの縁を打抜部分に嵌め合わせて、打抜部分の突き当たりに設けられた円形の空隙にカップの縁を嵌め込んで固定することにより、バッグをカップ上で安定した状態で保持できる上置式支持具付バッグが開示されている。   Furthermore, in Japanese Patent Application Laid-Open No. 10-85136, when using a bag with a support tool comprising a bag for extracting a palatable beverage and a paper support tool for holding the bag on the cup, the bag between the front and back sheets is widened. When the cup is opened and placed on the cup, a punching part is provided in the part where the lower end of the four sections provided in the lower part of the support comes into contact with the edge of the cup, and the edge of the cup is fitted to the punching part. There is disclosed a bag with an upper support that can hold the bag in a stable state on the cup by fitting and fixing the edge of the cup into a circular gap provided at the end of the punched portion.

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。また、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。

Recently, a bag with a complicated plastic or cardboard holding mechanism has been added, and when used, almost the entire bag is placed on the edge of the upper part of the cup. Is popular. However, these are complicated and 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.

上置式の嗜好性飲料抽出用バッグにおける支持具の構造を改良して、広範囲の口径や形状を有するカップの何れを使用しても、常に安定した状態に保持することができると共に、バッグの底部迄充分に広げて抽出性を高めることができ、更にカップとバッグとの間の構造部分を改善して、抽出操作の間より安定した状態に保持して抽出性を高め得る、嗜好性飲料用抽出バッグを提供しようとするものである。   By improving the structure of the support in the top-type palatable beverage extraction bag, it can always be kept stable regardless of the cup having a wide range of calibers and shapes, and the bottom of the bag It can be fully expanded to improve the extractability, and further improve the structure part between the cup and the bag and keep it more stable during the extraction operation to enhance the extractability. It is intended to provide an extraction bag.

本発明者等はコーヒー、紅茶等のディスポーザブルタイプの抽出用バッグをドリップ方式で使用する場合、広範囲な口径を有するカップの何れに使用する場合でも、バッグの口を充分に開かせることの他、更にカップの形状に拘わらず常に安定した状態に保持することができ抽出性を高めることを目的として、支持具の材質と構造について研究した。その結果、紙製支持シートとカップの縁を保持するための把手との中間に側面から見た場合、Ｖ字状に折り畳まれ伸縮自在な接続部が２重に介在する構成に到達した。   When the present inventors use a disposable type extraction bag such as coffee or tea in the drip method, in addition to sufficiently opening the mouth of the bag, when using any of the cups having a wide range of calibers, In addition, the material and structure of the support were studied for the purpose of improving the extractability by maintaining a stable state regardless of the shape of the cup. As a result, when viewed from the side in the middle between the paper support sheet and the handle for holding the edge of the cup, a configuration has been reached in which double-folded connecting portions that are folded in a V shape are interposed.

更に支持シートのＶ字状の折り目がカップの縁に掛かる部分が分割された構造を有すると共に、支持シートのカップの縁から外側に垂れる部分に鰭または、一つ或いは複数の突起を設けることにより、広範囲の口径や形状有するカップの何れにも充分に適合できるように構成されたものである。また、前記の支持シートのカップの縁から外側に垂れる部分に設けられた鰭の代わりに、一つ或いは複数の突起を設けた構造を有する抽出バッグも本発明に含まれている。これらの知見に基づいて本発明に到達した。   In addition, the support sheet has a structure in which the portion where the V-shaped fold of the support sheet hangs on the edge of the cup is divided, and by providing a ridge or one or a plurality of protrusions on the portion of the support sheet that hangs outward from the edge of the cup It is configured so as to be fully compatible with any cup having a wide range of apertures and shapes. Further, the present invention also includes an extraction bag having a structure in which one or a plurality of protrusions are provided in place of the bag provided on the portion of the support sheet that hangs outward from the edge of the cup. The present invention has been reached based on these findings.

Also included is a bag for extracting a palatable beverage according to claim 1 or 2 provided with a).

ここで、「紙製支持シート(3) 、(3′) 」の様に同じ番号に′を付けたものは、それぞれ表側、裏側の対称の位置にある同一の構造部分を示している。以下、本発明について詳しく説明する。   Here, the same number, such as “paper support sheets (3), (3 ′)”, with the same number indicates the same structural portion at the symmetrical position on the front side and the back side. The present invention will be described in detail below.

本発明の支持具付嗜好性飲料バッグの材質は、濾過性を有するシートであれば特に限定せず、広範囲の素材が使用可能である。この中、繊維径が約0.02μm 以下の超極細繊維を含む不織布は抽出性が優れているためより好ましい。例えば、コーヒーの苦すぎる原因となり易い抽出残渣や油脂の除去性に優れているためである。   The material of the palatable beverage bag with a support of the present invention is not particularly limited as long as it is a sheet having filterability, and a wide range of materials can be used. Among these, a nonwoven fabric containing ultrafine fibers having a fiber diameter of about 0.02 μm or less is more preferable because of its excellent extractability. For example, it is because it is excellent in the removal property of the extraction residue and fats and oils which are the cause of too much coffee.

抽出用バッグの形状は特に限定しないが、開口面積を大きくするためバッグの側面にギャザーを設けた形状も含まれている。更にバッグの下部の断面はＶ字形になっていると液切れが良好となるため好ましい。本発明のバッグには内容物を封入せずオープンの状態として、使用時適宜コーヒー粒子等内容物を入れてお湯を注入して使用するバッグの他、予めコーヒー粒子等がバッグの内部に封入されていて、使用時ミシン目等を引き裂いてバッグの口を開き、お湯を注入して使用するものも含まれている。   The shape of the extraction bag is not particularly limited, but includes a shape in which a gather is provided on the side surface of the bag in order to increase the opening area. Further, it is preferable that the cross section of the lower part of the bag is V-shaped because liquid breakage is improved. In the bag of the present invention, the contents are not encapsulated, but in an open state, the contents of coffee particles and the like are appropriately put in use, and the bag is used by injecting hot water, and coffee particles are encapsulated in the bag in advance. In addition, there are those that are used by tearing perforations and the like when in use, opening the mouth of the bag, and pouring hot water.

本発明の嗜好性飲料抽出用バッグはディスポーザブルで、ドリップタイプのコーヒー、紅茶等の抽出用バッグに紙製支持シートを取り付けたものである。使用前は紙製支持シートの構造部分が折り畳まれた形状となっている。使用時折り畳まれた紙製支持シートの先端部分をバッグを膨らませるように互いに反対方向に引っ張って、逆Ｖ字状の部分をカップの縁に掛けると、バッグとカップとの間に２重のＶ字状構造が形成される。また紙製支持シートの表裏のカップの縁に掛けられた部分が、図に示すようにそれぞれ分離された構造となっている。更にカップの外面を保持する鰭または突起及び、先端部の下端両側に斜めに内側へ折り返した部分の作用とも相まって、広範囲なサイズ及び形状を有する何れのカップに適用しても、高い密着性及び抽出時の安定性を保持できる。このため通常のコーヒー或いは紅茶用カップの他、デミタス型、ガラスコップ、朝顔型カップその他更に個性的な変形カップ等広範囲の形状を有するカップに適用しても高い抽出時の安定性が保持される特徴を有する。   The palatable beverage extraction bag of the present invention is disposable, and a paper support sheet is attached to an extraction bag for drip coffee or tea. Before use, the structural part of the paper support sheet is folded. Pulling the tip of the folded paper support sheet in the opposite direction so as to inflate the bag, and hanging the inverted V-shaped part on the edge of the cup, double the gap between the bag and the cup. A V-shaped structure is formed. Moreover, it has the structure where the part hung on the edge of the cup on the front and back of the paper support sheet was separated as shown in the figure. Furthermore, combined with the action of the ridges or protrusions that hold the outer surface of the cup and the part that is folded inwardly on both sides of the lower end of the tip, it can be applied to any cup having a wide range of sizes and shapes, The stability during extraction can be maintained. For this reason, even when applied to cups with a wide range of shapes such as demitas, glass cups, morning glory cups, and other unique cups in addition to ordinary coffee or tea cups, high stability during extraction is maintained. Has characteristics.

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微妙な影響を与える。例えば、香りやコク味が優れたコーヒーを入れるために、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 is a subtle difference in filterability depending on the material and structure of the bag, which has a subtle effect on the flavor of the resulting palatability beverage. For example, the most important property required for a filter in order to put coffee having 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、前記の様に広範囲な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得る素材として、繊維径が約0.02μm
以下の超極細繊維を含む不織布が好ましい。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、ポリエステル、ポリ乳酸、ポリプロピレン、ポリエチレン等が使用可能である。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も可能であり、ろ過性・抽出性と共にろ布に高い機械的性質を付与し得る特性がある。 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. However, as a material that can prevent the leakage of fine particles and improve the adsorption of fats and oils, the fiber diameter is 0.02μm
Nonwoven fabrics containing the following ultrafine fibers are preferred. The ultrafine fibers can be produced from, for example, a thermoplastic polymer by a melt blow method. As a kind of thermoplastic polymer, polyester, polylactic acid, polypropylene, polyethylene, or the like can be used. It is also possible to use such a nonwoven fabric layer of ultra-fine fibers and a composite nonwoven fabric of a support layer made of fibers of normal thickness, giving high mechanical properties to the filter fabric as well as filterability and extractability. There are characteristics to get.

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 coffee particles, tea, etc. can be enclosed inside and immersed in hot water or poured into hot water, as is generally used conventionally. 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及び弾性と共に、変形させた時その形状に保持できる可塑性も有するシートの意味である。例えば、少し厚みがある紙、例えばケント紙或いはプラスチックシート等も使用可能である。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. “Happy” means a sheet having a certain degree of rigidity and elasticity, such as Kent paper, and also having a plasticity that can be held in its shape when deformed. For example, a slightly thick paper such as Kent paper or a plastic sheet can be used. Moreover, since the handle holding part is normally used in the state immersed in hot water, the material which has water resistance is preferable.

従来抽出用バッグの紙製支持シートは、把手とそのベースとなる把手保持部との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等を介して接続された構造部分が挿入されている。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、中間部を介して２つのＶ字形に伸縮する構造が形成される。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、バッグが変形等の影響を受けることなく取り付けも容易で最適な状態に保持できる特徴がある。   Conventionally, a paper support sheet for an extraction bag has been composed of two parts, a handle and a handle holding part serving as a base thereof. In the present invention, a perforation or the like is interposed between the handle holding part and the handle. The connected structural parts are inserted. For this reason, when the handle is caused, a structure is formed between the handle and the handle holding portion so as to expand and contract in two V shapes via the intermediate portion. For this reason, regardless of the distance between the extraction bag and the lip of the cup, the bag can be easily mounted and maintained in an optimum state without being affected by deformation or the like.
