【発明の属する技術分野】
本発明は、濾過具さらに詳しくは、コーヒー、紅茶等の使い捨て可能な濾過具に関する。
【0002】
【従来の技術】
従来より、カップ等の容器上面に載置可能な濾過具本体と、内部にコーヒー、紅茶等を収容可能な袋体とからなる濾過具が幅広く使用されている。この種の濾過具は、容器上面に濾過具本体を載置し、前期袋体に熱湯等を注ぐことにより抽出液を容器内部に流下させるものである。
【0003】
この種の濾過具としては、特許第3032724号公報記載のものが公知である。該公報記載の従来のコーヒー等の濾過具(図5)は、濾過具本体1と濾過袋5からなり、図6に示すように、まず、両帯片2,2を拡開し、環状にして、カップ9等の容器9aの上部の外側面に挟持部4の内側面が当接するよう、濾過具本体1をカップ9に取り付ける。このようにカップ9に濾過具本体1を取り付けた後に、載置片3の中央付近を押し、カップ9の内側方向に載置片3を突出させて載置部3aを形成する。その際、中央の谷折線3c、両端の山折線3d,3dが設けられているので、容易で且つ確実に載置部3aを形成することができる。載置片3の中央付近を押し込み載置部3aを形成した後、該載置部3a下縁をカップ9の開口部上縁に当接させることで、濾過具本体1をカップ9に載置して固定する。
【0004】
このように濾過具本体1をカップ9に載置したのち、濾過袋5にコーヒーの粉末、紅茶等の所定のものを収容して、前記濾過袋5に熱湯等を注ぐことにより、抽出液がカップ9内に流下する。
【0005】
【発明が解決しようとする課題】
前記公報記載の濾過具では、図5に示すように帯片2、2を拡開すると、谷折線3c,山折線3d、3dが設けられているので、濾過袋5の上部が剥離されて、帯片2は環状になるが、載置片3には中央部に谷折線3cが設けられ、且つ、両端部に山折線3d,3dが設けられていて、載置片3の折り曲げが容易且つ確実になるように加工されているものの、上記拡開に際し載置片3も帯片2の輪郭に沿って同時に環状に形成されるという現象が生じた。
【0006】
このため、載置部3aを形成するに至らないため、該載置部3a下縁をカップ9の開口部上縁に当接させ濾過具本体1をカップ9に載置して固定するためには、指先等により載置片3を内側に押す動作が必要になり、使用時の簡便性を売り物にする濾過具においてなお手間を要する点が課題であった。
【0007】
本発明は、以上のような問題点を解決するためになされたもので、拡開してコップ等に極めて取り付け易く且つそのままコップに安定して固定することができる手間の要らない濾過具を提供することを課題とする。
【0008】
【課題を解決するための手段】
上記課題を解決するためになされた本発明に係わる請求項1記載の濾過具は、カップ等の容器(9a)上面に載置可能な濾過具本体(1)と、内部にコーヒー、紅茶等を収容可能な袋体(5a)とからなり、容器(9a)上面に濾過具本体(1)を載置し袋体(5a)に熱湯等を注ぐことにより抽出液を容器内部に流下すべく濾過具本体(1)に袋体(5a)が取り付けられた濾過具であって、濾過具本体(1)は一対の帯片(2)を環状に拡開可能に形成されてなり、帯片(2)には、中央部に夫々容器(9a)上部を外側より挟持可能な一対の挟持部(4)が設けられてなり、且つ、挟持部(4)の上側には容器(9a)の開口部上縁と当接可能な載置部(3a)が突設されてなる濾過具であり、載置部(3a)が載置片(3)から構成され載置部(3a)のほぼ中央部内面と袋体(5a)の外面とが貼着されており、載置片(3)に少なくとも2本の折れ込み筋(3d)を形成してなることを特徴とする。
【0009】
本発明においては、載置片(3)に少なくとも2本の折れ込み筋(3d)が形成されており、複数の折れ込み筋のうち最も内側に形成されている2本の折れ込み筋(3d)の間で載置部(3a)と袋体(5a)とが貼着(3b)されていることが好ましい。
【0010】
このように、載置部(3a)のほぼ中央部内面と前記袋体(5a)とが貼着されているので、そして、載置片(3)には少なくとも2本の折れ込み筋(3d)が形成されているので、帯片2、2を拡開した時載置部(3a)が折れ込み筋(3C,3d)に沿って内側に自動的に退行することで容易に形成することができる。また、載置片(3)と濾過袋(5)を容易に剥離できる程度の強度で接着(3b)することにより、濾過具本体(1)の両帯片(2、2)を拡開し、環状にすると、少なくとも2本の谷折線(3c、3c)の折れ込み線がそれぞれ自動的に形成されることを特徴とする。
【0011】
本発明において、載置片(3)の両端に2本の折れ込み筋(3c)が形成されており、さらにその内側に2本の折れ込み筋(3d)が形成されていて、内側の2本の折れ込み筋(3d)のほぼ中間部において載置部(3a)と袋体(5a)とが貼着(3b)されていることが好ましい。
【0012】
このように、載置片(3)の両端に2本の折れ込み筋(3d)が形成されているので、濾過具本体(1)の両帯片(2、2)を拡開し、環状にすると、山折線(3d、3d)の山折り線と少なくとも2本の谷折線(3c)の折れ込み線がそれぞれ自動的に折れて載置部(3a)が形成されることを特徴とする。
【0013】
さらに、本発明において、折れ込み筋(3c,3d)は、貫通部分と非貫通部分とが交互にあるミシン目からなることが好ましい。このような構成にすることによって、摘み部A,Aを摘んで帯片(2、2)を拡開すると、載置片(3)の内側への折り曲げがさらに容易になる。貫通部分は、折れ込み筋(3c、3d)全体の長さの50%以上であるのが好ましく、75%以上であることがさらに好ましい。
【0014】
本発明において、載置部(3a)と袋体(5a)との接着(3b)は、熱板シール、超音波シール、あるいはホットメルトによりなされることが好ましい。すなわち、帯片2、2を拡開したとき、袋体(5a)に引張られて内側へ折り曲げられた載置片(3)が手指により内側に押す操作がなくても自動的に形成される程度の貼着強度であればよいため、ノリなどでなくとも前記の貼着方法でよいのである。
【0015】
袋体(5a)と貼着する載置部(3a)の貼着面にポリエチレンコートが施されていることが好ましい。
さらに本発明においては、載置部(3a)と接着する部位の袋体(5a)が、不織布またはパルプにポリプロピレンおよび/またはポリエチレンの繊維を混同し抄紙した複合材料シートで構成されることが好ましい。
【0016】
本発明の濾過具において、載置部(3a)と袋体(5a)との貼着部(3b)の形状は直径2〜15mmの大きさのほぼ円形状、3〜12mmのほぼ正方形状、1〜7mmの辺と3〜20mmの辺の長さを有するほぼ長方形状、のいずれかであることが好ましく、接着部の個数は1乃至3個であることが好ましい。
【0017】
【発明の実施の形態】
次に本発明の濾過具の一実施形態について図1、図2に示す如く、濾過具本体1と濾過袋5とからなる濾過具について説明する。
【0018】
濾過具本体1は、二つの帯片(2)が両端部の折曲部(2a)で互いに連結された形態からなる。具体的には、該濾過具本体(1)は、帯状の厚紙、防水加工を施した紙、プラスチックス製シート等の剛性を有する材質のシートを環状に連結して、この環状のシートを前記折曲部(2a)で折り畳むことにより、二つの帯片(2)が環状に拡開するように形成されている。
【0019】
ここで、濾過具本体(1)(帯片2)は復元力を有する材料からなるため、拡開すると元の折り畳まれた状態に戻ろうとして両帯片(2,2)には互いに他の帯片側に向かう力が働く。
【0020】
夫々の帯片(2)には、中央下端より挟持部(4)が突設されており、両帯片(2,2)を拡開して濾過具本体(1)をカップ(9)を挟持するように載置する際に、前記一対の挟持部(4,4)と該一対の挟持部(4,4)の上側付近の帯片(2,2)により、カップ(9)は確実に挟持される。
【0021】
ここで、挟持部(4)と該挟持部(4)の上側付近に位置する帯片(2)の一部は、濾過具本体(1)をカップ(9)に取り付ける際にその内側面がカップ(9)の側面上部に当接し、カップ(9)を挟持する。
【0022】
前記帯片(2)の下側の中央付近には夫々挟持部(4)が設けられ、該挟持部(4)の上側には、窓部(7)が設けられている。また、該窓部(7)の下縁(7a)と一定隙間を開けるべく切欠部(8)が図1の横方向に設けられている。そして、該窓部(7)と前記切欠部(8)の上縁に囲まれた領域に、谷方向(他方の帯片2側)に折り曲げ可能である載置片(3)が形成されている。該載置片(3)には中央部寄りに谷折線(3d、3d)が設けられており、且つ、両端部に山折線(3c、3c)が設けられており、載置片(3)の折り曲げが容易に且つ確実になるように加工されている。
【0023】
そして、このように構成された前記帯片(2)の中央部付近には濾過紙等からなる袋体(5a)(以下、濾過袋(5)という)の取り付け部が夫々貼着されて、濾過袋(5)が貼着部(3b)で帯片(2)に取り付けられている。
【0024】
このように、濾過袋(5)の上縁は帯片(2)の中央部付近に取り付けられているので、一対の帯片(2)の拡開で、焙煎粉砕したコーヒー等を収容した濾過袋(5)はカップ(9)内で中央付近に位置することになり、コーヒー粉末等を収容した濾過袋(5)の自重が帯片(2,2)を引き寄せるのでカップ(9)を挟持する力が更に強くなる。
【0025】
次に、前述のように構成された濾過具の使用方法について図3,4に基づいて説明する。
まず、摘み部(A,A)を摘んで両帯片(2,2)を拡開し、環状にして、カップ(9)等の容器(9a)の上部の外側面に挟持部(4)の内側面が当接するよう、濾過具本体(1)をカップ(9)に取り付ける。このようにカップ(9)に濾過具本体(1)を取り付けると、載置片(3)に設けた複数の折れ込み筋の屈曲でカップ(9)の内側方向に載置片(3)は自動的に突出して載置部(3a)を形成する。その際、山折線(3c、3c)、谷折線(3d,3d)が設けられているので、容易で且つ確実に載置部(3a)を形成することができる。載置部(3a)を形成した後、該載置部(3a)下縁がカップ(9)の開口部上縁に当接されることで、濾過具本体(1)はカップ(9)に載置固定される。
【0026】
本発明では,帯片(2)の載置片(3)と袋体(5a)とが弱い接着力であっても帯片(2)の拡開で載置片(3)が機能する、すなわち折り返りして一旦折り返ればた易くは元に戻らないように構成されている。
【0027】
形状、寸法は限定されるものではないが好適な数値を例示して以下にこの構成を説明する。先ず、載置片(3)の上縁(7a)を曲率半径で約40〜60mm前後にとることで、稍厚手の帯片(2)の載置片(3)は一度の折り返しで戻りにくくなる。また、ミシン目の折れ込み筋(3d)の垂直線に対する角度αを20゜〜40゜にすると載置片(3)は袋体(5a)との接着力で内側に引張られたとき、カップ(9)の入り口に載置部(3a)が入り易い角度に内折れする。
【0028】
この場合折れ込み筋(3d)の角度αと外側に設けられた折れ込み筋(3c)の垂直線に対する角度βとに角度の差をつけ、例えばα=β+約10°で表わされるようにβを10°〜30°にすることが好ましい。このように、ミシン目の折れ込み筋(3c)、(3d)は4本設けることで、貼着部(3b)における接着力で載置片(3)が内折れするとき、屈折による干渉がなくスムーズに折れる。そして、4本の折れ込み筋を有する載置片(3)の下縁(3a)が載置部をなし、この載置部(3a)がカップ(9)の上縁(9b)と接することになる。
【0029】
このように濾過具本体(1)をカップ(9)に載置したのち、コーヒーの粉末、紅茶等の所定のものを収容した濾過袋(5)に熱湯等を注ぐことにより、抽出液がカップ(9)内に流下する。
【0030】
また、図3に示すように、紅茶用のカップ等、カップの上縁が外側に開いた場合には、切欠部(8)があるので、カップの鍔(上縁)(9b)が切欠部(8)に入り込み、上下方向にも安定した状態でカップ(9)に載置することができる。こうして、カップ(9)に対して濾過具本体(1)に上方への力がかかっても、濾過具本体(1)が不用意に傾いたりカップ(9)から脱落することがない。
【0031】
【発明の効果】
本発明の効果として、本濾過具をカップに載せる時、濾過具本体1の両帯片2、2を拡開させると環状になり、併せて谷折線3d、谷折線3d、山折線3c、山折線3cにより載置部(3a)が自動的に形成され、手指で押さなくても簡便に使用できる使い易い濾過具を得た。

Next, a method for using the filter configured as described above will be described with reference to FIGS.
First, the picking part (A, A) is picked and both the strips (2, 2) are expanded to form an annular shape, and the sandwiching part (4) is attached to the outer surface of the upper part of the container (9a) such as the cup (9) The filter body (1) is attached to the cup (9) so that the inner side surface of the filter comes into contact. When the filter body (1) is attached to the cup (9) in this way, the placement piece (3) is moved inwardly of the cup (9) due to the bending of a plurality of folding muscles provided on the placement piece (3). It automatically protrudes to form the mounting portion (3a). At this time, since the mountain fold lines (3c, 3c) and the valley fold lines (3d, 3d) are provided, the mounting portion (3a) can be formed easily and reliably. After forming the mounting portion (3a), the lower edge of the mounting portion (3a) is brought into contact with the upper edge of the opening of the cup (9), so that the filter body (1) is attached to the cup (9). Placed and fixed.
[0026]
In the present invention, even if the placing piece (3) of the strip (2) and the bag (5a) have a weak adhesive force, the placing piece (3) functions by spreading the strip (2). That is, it is configured so that it does not easily return after being folded and once folded.
[0027]
Although the shape and dimensions are not limited, this configuration will be described below by illustrating suitable numerical values. First, by placing the upper edge (7a) of the mounting piece (3) at a radius of curvature of about 40 to 60 mm, the mounting piece (3) of the thick strip (2) is difficult to return after being folded once. Become. Further, when the angle α with respect to the vertical line of the perforation fold line (3d) is set to 20 ° to 40 °, when the placing piece (3) is pulled inward by the adhesive force with the bag (5a), the cup It bends at an angle at which the mounting portion (3a) can easily enter the entrance of (9).
[0028]
In this case, an angle difference is made between the angle α of the folding line (3d) and the angle β with respect to the vertical line of the folding line (3c) provided outside, for example, α = β + about 10 °. It is preferable to set β to 10 ° to 30 °. In this manner, by providing four folding lines (3c) and (3d) of the perforation, when the placing piece (3) is folded inward due to the adhesive force in the sticking part (3b), interference due to refraction occurs. It breaks smoothly. And the lower edge (3a) of the mounting piece (3) having four folding lines forms the mounting portion, and this mounting portion (3a) is in contact with the upper edge (9b) of the cup (9). become.
[0029]
After placing the filter body (1) in the cup (9) in this way, the hot water or the like is poured into the filter bag (5) containing a predetermined thing such as coffee powder or tea, so that the extract is cupped. (9) Flow down.
[0030]
Also, as shown in FIG. 3, when the upper edge of the cup, such as a tea cup, opens outward, there is a notch (8), so the cup's ridge (upper edge) (9b) is the notch. (8) Enters and can be placed on the cup (9) in a stable state in the vertical direction. Thus, even if an upward force is applied to the filter body (1) with respect to the cup (9), the filter body (1) does not inadvertently tilt or drop off from the cup (9).
[0031]
【The invention's effect】
As an effect of the present invention, when the filter is placed on a cup, the two strips 2 and 2 of the filter main body 1 are expanded to form a ring, and at the same time, a valley fold line 3d, a valley fold line 3d, a mountain fold line 3c, a mountain fold The placing part (3a) was automatically formed by the line 3c, and an easy-to-use filter that could be used simply without being pushed by a finger was obtained.
