【発明の属する技術分野】
本発明は、飲料抽出バッグに関するものである。更に詳しく述べるならば、本発明は、コーヒー、紅茶、緑茶その他の飲用材料を、水又は熱湯等で抽出するための飲料抽出バッグに関するものである。本発明の飲料抽出バッグは、特に抽出に際し、その上端を開口し、その1対の係止片を引き起してカップ等の容器の上縁部に係止し、バッグの開口状態を安定に維持しながら抽出するのに好適なものである。
【0002】
【従来の技術】
従来の飲料抽出バッグの大多数は、濾紙袋本体内にコーヒー粉、又は茶葉などを収容し、この濾紙袋本体の両面上半部に厚紙製の支持枠を取りつけたものであって、このような飲料抽出バッグは、例えば、特開平4−13568号公報などに開示されている。しかしながら、上記の構成を有する飲料抽出バッグにおいて、その支持枠は、カップなどの容器の上縁部に載置されるだけで係止されていないため、抽出バッグの支持状態が不安定であって、このためその上方から熱湯を注下する際に抽出バッグが滑り、時には容器から外れ易いという不都合があった。また上記のような従来の抽出バッグにおいては、その開口状態を安定に維持することが難しく、抽出操作を円滑に行うことが困難であった。さらに、上記のような従来の抽出バッグにおいては、支持枠の腕部が、濾過袋の外に伸び出しているため、抽出バッグの寸法が大きくなり、従って、それを収容する外装袋の寸法も大きくなり経済的不利を生ずるなどの問題点も有していた。
【0003】
【発明が解決しようとする課題】
本発明は、飲料の抽出操作が簡単容易であり、カップなどの容器の上縁部に安定して係止することができ、かつその開口部を広く安定して維持することができる飲料抽出バッグを提供しようとするものである。
本発明は、さらに、カップなどの容器の上縁部に対する係止状態がきわめて安定しており、このため抽出の際に、バッグ内の被抽出物を攪拌することが可能な飲料抽出バッグを提供しようとするものである。
【0004】
【課題を解決するための手段】
本発明は、飲料抽出バッグの係止片支持部に補強用畝を設け、さらに必要により、係止片にも補強用畝を設けることによって、抽出バッグの係止状態を安定化し、それによって上記課題の解決に成功したものである。
【0005】
本発明の飲料抽出バッグは、通水濾過性シート材料からなり、互いに対向する2面部を有し、かつ上端に開口部を有する濾過袋本体と、前記濾過袋本体の両面にそれぞれ一個ずつ固定された一対の係止部材とを有し、前記一対の係止部材が、前記濾過袋本体の両面に固定された一対の支持体と、この支持体から前記濾過袋の横方向に沿って引き起こし可能に伸び出ている1対の係止片からなり、前記支持体は、前記係止片に連続してこれを支持し、前記濾過袋の縦方向に伸びる係止片支持部と、この係止片支持部の上下端部分から、前記係止片の上辺および下辺に沿って伸び出ている上下1対の保形部とを有し、前記1対の係止片が、それぞれ1個の係止用凹部を有している抽出バッグにおいて、
前記支持体の係止片支持部に、その縦方向に沿って伸びる1個以上の補強用畝が形成されていることを特徴とするものである。
【0006】
本発明の抽出バッグにおいて前記係止片の各々に、その伸び出し方向にほぼ平行に伸びる1個以上の補強用畝が形成されていることが好ましい。
また、本発明の抽出バッグにおいて前記係止片とそれに連続している前記支持体との境界部に1本の折り曲げ用溝が連続して、又は断続して形成されていることが好ましい。
さらに、本発明の抽出バッグにおいて前記濾過袋本体の底部にマチが形成されており、未使用時には内側に折り込まれていることが好ましい。

上記本発明の抽出バッグにおいては、前記被抽出物質がコーヒー粉末であり、前記濾過袋本体の封止上端部に引き裂き用ミシン目が形成されていることが好ましい。
【0007】
【発明の実施の形態】
本発明の飲料抽出バッグの構成を添付図面を参照して詳しく説明する。
図1には、本発明の飲料抽出バッグの一実施態様の正面説明図であって、抽出バッグ1の濾過袋本体2は、通水濾過性シート材料からなり、互に対向する2面部、すなわち表面部3および背面部4を有している。濾過袋本体2の表背面部3,4の各々に、それぞれ1個づつ1対の係止部材5が固定されている。この係止部材5の中心は、濾過袋本体2の表背面部3,4の各々の、中心よりも上側にかたよって配置されていることが好ましい。濾過袋本体2の上端6は、濾過袋本体2中に被抽出物を収容し封止するまでは、開口している。また、濾過袋本体2の底部は、マチ7が形成されていることが好ましく、抽出バッグの未使用状態においては、内側に折り込まれており、この折り込み端7aが、図1において点線により示されている。
【0008】
本発明の抽出バッグにおいて、1対の係止部材5の各々は、図1に示されているように、濾過袋本体2の1面に固定された支持体8と、この支持体から、濾過袋本体の横方向に沿って、引き起し可能に伸び出ている係止片9からなるものである。この支持体8は、係止片9に連続してこれを支持し、濾過袋本体2の縦方向に伸びる係止片支持部8aと、この係止片支持部8aの上下両端部から、係止片9の上辺および下辺に沿って伸び出ている上下1対の保形部8b,8cとを有している。また1対の係止片9の各々には、1個の係止用凹部9aが形成されている。このような係止片9は、係止部材5に係止片9が支持体88係止片支持部8aのみに連続し、保形部8b,8cから分離し得るように切り込みを入れることによって形成することができる。
【0009】
本発明の抽出バッグ1において、支持体8の係止片支持部8aには、その縦方向に沿って伸びる1個以上の、好ましくは1〜3個の、補強用畝10が形成されていて、それによって係止片支持部8aが補強されている。この補強用畝10は、係止片支持部8aの上端部から下端部まで連続して伸びていてもよいし、或は、図1に示されているように2以上の部分に分かれて断続的畝を形成していてもよい。また、補強用畝10は波板状(畝の裏側は溝を形成している)に形成されていてもよい。さらに、係止片9と、それに連続している係止片支持部8aとの境界部には、折り曲げ線が形成されていてもよく、この折り曲げ線は、図1に点線により示されているように折り曲げ用溝11を形成していてもよい。またこの折り曲げ線は連続していてもよく、或は断続していてもよい。
濾過袋本体2内に被抽出材料が収容され、濾過袋本体2の上端開口部6が封止されている場合、この封止上端部分に引き裂き用ミシン目6aを設けて、このミシン目に沿って、封止上端部を引き裂き易いようにしてもよい。或は、上記引き裂き用ミシン目に代えて、表・背面部の上端を剥離可能に接着、又は融着してもよい。
【0010】
本発明の抽出バッグの濾過袋本体を形成する通水濾過性シートは、耐水性のある濾過シート、例えば、メルトブロー法、スパンボンド法又はサーマルボンド法で作られ、かつ抽出原料中に含まれる微粒子の漏出防止や油脂分の吸着除去性に優れている不織布を用いることが好適で、これらを形成する熱可塑性ポリマーとしては、ポリオレフィン系、ポリエステル系、ポリアミド系等を使用することが好ましく、これらの中でもポリエチレン、ポリプロピレン等から選ばれたものが最も好ましい。また、係止部材を形成する材料は、実用上十分な耐水性を有し、変形(湾曲)が容易で、かつその形状を保持できるシート材料、例えば十分な厚みのある白板紙、紙コップ用シート或いはプラスチック製シート等から選ぶことができる。係止部材の支持体は、濾過袋本体に接着されているか、この接着層は、実用上十分な耐水性を有することが必要で、例えば熱接着型のポリオレフィン共重合樹脂、エチレン−アルキルアクリレート共重合樹脂、エチレン−酢酸ビニル共重合樹脂或いはポリエステル共重合樹脂などによって接着されていることが好ましい。
【0011】
本発明の抽出バッグを用いて抽出を行う場合の状況が図2に示されている。図2において、濾過袋本体2の上端が封止されているときは、これを開放し、濾過袋本体2の表面部3および背面部4の1対の係止片9を、係止片支持部8aの折り曲げ線11において外側に折り曲げて、係止片9を引き起す。この係止片9の引き起し操作は、折り曲げ線11を軸にして、係止片9を外側に旋回させ、濾過袋本体2の表・背面部3,4の接続側線12をはさんでその両側外方に引張るように行われるから、この操作により自然に濾過袋上端は開口する。また、濾過袋底部にマチ7が形成されている場合は、係止片9の引き起こしによってこのマチ7も図2に示されているように展張される。しかも、支持部8の上下保形部8b,8cは、濾過袋本体2の拡張に伴って容易に変形し、拡張力が解除されても、濾過袋本体2をその拡張形状に保持することができる。
【0012】
本発明の抽出バッグにおいて、図3に示されているように係止片9の各々に、その伸び出し方向(濾過袋本体の横方向)にほぼ平行に伸びる1個以上の補強用畝13が形成されていることが好ましい。この補強用畝13は、係止片9が引き起され、その係止凹部9aにおいて、カップなどの容器の上縁部に係止され、抽出バッグ、その内容物、および注加された水又は熱湯の重量が係止片9に負荷されたとき、係止片9の変形を防止するようにこれを補強し、抽出バッグを所望の位置および形状に保持するために有効なものである。補強用畝13の数には格別限定はなく、1個以上、好ましくは、互に平行に2〜5個である。補強用畝13は、図3に示されているように、係止片の、係止凹部9aより先端部分のみに形成されていてもよく、或は、これらの補強畝13が、係止片支持部8aとの境界線まで延長されていてもよい。補強畝12は波板状に形成されていてもよい。係止片支持部補強用畝10および係止片補強用畝13を、波板状に形成するには、係止部材5用シートの所定位置に、裏側から所定形状のエンボスを施せばよいが、このエンボス処理により当該畝部は圧縮され、その密度が高くなり従ってその曲げ剛性が増大するため、その補強効果が一層増強される。
【0013】
図4には、本発明の抽出バッグをカップの上縁部に係止して抽出を行う場合の状況が示されている。図4において、抽出バッグ1に被抽出物14(コーヒーなど)が収容されており、その上端部6が封止されているときは、切り取り、引き裂き、又は剥離により封止を開放し、濾過袋本体2の表・背面部3,4の係止部材5から係止片9を引き起す。このとき、前述のように、係止片を介して、表背面部3,4に、それを外側に拡張する力が作用するから、上端部は開口し、折り込まれた底部のマチは展張する。
【0014】
上記の抽出バッグの1対の係止片の係止凹部9aを図4に示されているようにカップ15の上縁部15aに係合すれば、濾過袋本体2は、支持体により、その開口形状に保持され安定してカップ上縁部に係止される。このとき、カップの形状・寸法に応じて、1対の係止片9の開き角度を適宜に調整することにより、カップに適切に係合することができる。
【0015】
抽出バッグに予じめ被抽出材料が収容されている場合は、上部開口端より水又は熱湯を注入すれば、所望の抽出を行うことができる。また、抽出バッグに予じめ被抽出材料が収容されていない場合は、抽出バッグを開口し、容器に係止した後所望量の被抽出材料を濾過袋本体中に入れ、これに水、又は熱湯を注いで抽出する。また、濾過袋本体底部にマチが設けられているときは、濾過袋本体は、円筒状、又は楕円筒状に拡張し、この形状は、係止片支持部に設けられた補強用畝により安定化されているので係止片は、ほぼ垂直姿勢に保持されるからこの係止片による濾過袋本体の支持状態の安定性が向上し、かつ被抽出材料に対し、効率のよい蒸し効果を与えることができる。また、係止片に補強用畝が形成されている場合には、この係止片をさらに補強し、かつその係止状態を一層安定化させることができる。
【0016】
【発明の効果】
本発明の飲料抽出バッグにおいて、係止部材から引き起される係止片を支持する係止片支持部が補強用畝により補強され、かつその形状が安定化されているため、抽出バッグをカップなどの容器の上縁に係止して抽出操作を行うときに抽出バッグの係止状態を安定化し、抽出操作の容易性、迅速性および安全性を著るしく向上させることができる。

In the extraction bag of the present invention, as shown in FIG. 1, each of the pair of locking members 5 includes a support 8 fixed to one surface of the filter bag body 2, and a filtration from the support 8 The locking piece 9 extends so as to be raised along the lateral direction of the bag body. The support body 8 supports the engagement piece 9 continuously, and engages with an engagement piece support portion 8a extending in the longitudinal direction of the filter bag body 2 and both upper and lower ends of the engagement piece support portion 8a. It has a pair of upper and lower shape retaining portions 8b, 8c extending along the upper and lower sides of the stopper piece 9. Each of the pair of locking pieces 9 is formed with one locking recess 9a. Such a locking piece 9 is formed by cutting the locking member 5 so that the locking piece 9 is continuous only with the support 88 locking piece support portion 8a and can be separated from the shape retaining portions 8b and 8c. Can be formed.
[0009]
In the extraction bag 1 of the present invention, the locking piece support portion 8a of the support 8 is formed with one or more, preferably 1 to 3, reinforcing ridges 10 extending along the longitudinal direction. Thereby, the locking piece support portion 8a is reinforced. The reinforcing rod 10 may extend continuously from the upper end portion to the lower end portion of the locking piece support portion 8a, or may be divided into two or more portions as shown in FIG. A target may be formed. Further, the reinforcing ridge 10 may be formed in a corrugated plate shape (a groove is formed on the back side of the ridge). Furthermore, a fold line may be formed at a boundary portion between the locking piece 9 and the locking piece support portion 8a continuous thereto, and this fold line is indicated by a dotted line in FIG. In this way, the bending groove 11 may be formed. Further, the fold line may be continuous or intermittent.
When the material to be extracted is accommodated in the filter bag main body 2 and the upper end opening 6 of the filter bag main body 2 is sealed, a tear perforation 6a is provided at the upper end of the seal, and along the perforation. Thus, the sealing upper end may be easily torn. Alternatively, instead of the tear perforation, the upper ends of the front and back portions may be adhered or fused in a peelable manner.
[0010]
The water-permeable filter sheet forming the filter bag body of the extraction bag of the present invention is a water-resistant filter sheet, for example, fine particles made by a melt blow method, a spun bond method or a thermal bond method and contained in the extraction raw material It is preferable to use a nonwoven fabric that is excellent in preventing leakage of oil and absorbing and removing oil and fat, and as the thermoplastic polymer forming these, it is preferable to use polyolefin-based, polyester-based, polyamide-based, etc. Among these, those selected from polyethylene, polypropylene and the like are most preferable. The material forming the locking member is a sheet material that has sufficient water resistance for practical use, can be easily deformed (curved), and can retain its shape, for example, a sufficiently thick white paperboard, paper cup A sheet or a plastic sheet can be selected. The support of the locking member must be adhered to the filter bag body, or this adhesive layer must have sufficient water resistance for practical use. For example, a heat-bonding type polyolefin copolymer resin or ethylene-alkyl acrylate copolymer is required. It is preferable that they are bonded with a polymer resin, an ethylene-vinyl acetate copolymer resin or a polyester copolymer resin.
[0011]
The situation in the case of performing extraction using the extraction bag of the present invention is shown in FIG. In FIG. 2, when the upper end of the filter bag body 2 is sealed, this is opened, and the pair of locking pieces 9 of the front surface portion 3 and the back surface portion 4 of the filtration bag body 2 are supported by the locking pieces. The locking piece 9 is pulled up by bending outward at a fold line 11 of the portion 8a. The pulling operation of the locking piece 9 is performed by turning the locking piece 9 around the folding line 11 and sandwiching the connection side line 12 between the front and back surfaces 3 and 4 of the filter bag body 2. Since it is performed so as to be pulled outward on both sides, the upper end of the filter bag is naturally opened by this operation. When the gusset 7 is formed at the bottom of the filter bag, the gusset 7 is also extended as shown in FIG. In addition, the upper and lower shape retaining portions 8b and 8c of the support portion 8 are easily deformed as the filter bag body 2 is expanded, and can hold the filter bag body 2 in its expanded shape even when the expansion force is released. it can.
[0012]
In the extraction bag of the present invention, as shown in FIG. 3, each of the locking pieces 9 is provided with one or more reinforcing rods 13 extending substantially parallel to the extending direction (lateral direction of the filter bag main body). Preferably it is formed. The reinforcing bar 13 is raised by the locking piece 9 and is locked to the upper edge of a container such as a cup in the locking recess 9a, so that the extraction bag, its contents, and the added water or When the weight of hot water is applied to the locking piece 9, it is reinforced to prevent the locking piece 9 from being deformed, and is effective for holding the extraction bag in a desired position and shape. The number of reinforcing bars 13 is not particularly limited, and is 1 or more, preferably 2 to 5 in parallel with each other. As shown in FIG. 3, the reinforcing bar 13 may be formed only on the tip of the locking piece from the locking recess 9a. Alternatively, the reinforcing bar 13 may be a locking piece. You may be extended to the boundary line with the support part 8a. The reinforcing rod 12 may be formed in a corrugated plate shape. In order to form the locking piece supporting portion reinforcing rod 10 and the locking piece reinforcing rod 13 in a corrugated plate shape, it is only necessary to emboss a predetermined shape from the back side at a predetermined position of the locking member 5 sheet. The embossing process compresses the collar, increasing its density and thus increasing its bending rigidity, thereby further enhancing its reinforcing effect.
[0013]
FIG. 4 shows a situation in which extraction is carried out by locking the extraction bag of the present invention to the upper edge of the cup. In FIG. 4, when an extraction object 14 (coffee or the like) is accommodated in the extraction bag 1 and its upper end 6 is sealed, the sealing bag is opened by cutting, tearing, or peeling, and a filter bag. The locking piece 9 is pulled up from the locking member 5 of the front and back portions 3 and 4 of the main body 2. At this time, as described above, a force for expanding the front and back surface portions 3 and 4 to the outside acts on the front and back surface portions 3 and 4 through the locking pieces, so that the upper end portion is opened and the folded bottom gusset is expanded. .
[0014]
When the engaging recess 9a of the pair of engaging pieces of the extraction bag is engaged with the upper edge 15a of the cup 15 as shown in FIG. 4, the filter bag body 2 is supported by the support. It is held in the opening shape and is stably locked to the upper edge of the cup. At this time, it is possible to appropriately engage the cup by appropriately adjusting the opening angle of the pair of locking pieces 9 according to the shape and dimensions of the cup.
[0015]
When the material to be extracted is stored in the extraction bag in advance, desired extraction can be performed by injecting water or hot water from the upper opening end.
