以下、本発明を実施するための第1の実施形態について詳細に説明する。
図1は、第1の実施形態にかかる濾過具1の使用状態を示す斜視図であり、図2は、使用前の濾過具1の正面図である。
図1に示すように、濾過具1は、コーヒー、紅茶等嗜好性飲料の被抽出材101を収容する濾過袋10と、内部に濾過袋10を保持する支持具20とを有して構成される。そして、濾過具1は、カップ等の容器100の開口側上縁に載置される。
(First embodiment)
Hereinafter, a first embodiment for carrying out the present invention will be described in detail.
FIG. 1 is a perspective view showing a use state of the filter 1 according to the first embodiment, and FIG. 2 is a front view of the filter 1 before use.
As shown in FIG. 1, the filter 1 includes a filter bag 10 that contains a material to be extracted 101 of a coffee or tea-preferred beverage, and a support 20 that holds the filter bag 10 inside. The And the filter 1 is mounted in the opening side upper edge of containers 100, such as a cup.

ここで、濾過袋10は、例えば、濾紙、不織布、又は、ポリプロピレン及びポリエチレン繊維の少なくともいずれか一つをパルプに混和し抄紙した材料等で構成される。濾過袋10は、1枚の材料が底辺11にて折られ側面12にて熱接合されて、袋形状を構成している。濾過袋10は、開口部13側が底辺11側に対してやや広がった台形形状を有している。濾過袋10は、内部に、例えば、紅茶、ウーロン茶、緑茶、麦茶等の茶葉や焙煎粉砕したコーヒー豆等の被抽出材101が収納される。
支持具20は、例えば、ポリエチレン等で防水加工を施した厚紙、プラスチック製シート等の可撓性を有する材料で構成される。支持具20は、横長帯状の台紙(略長方形状の薄板)が中央で折られ重ねられ(後述)、短辺21側にて接合されて環形状に拡開可能に構成される。尚、支持具20の展開形状は図3を用いて後述する。
Here, the filter bag 10 is made of, for example, a filter paper, a non-woven fabric, or a material obtained by making paper by mixing at least one of polypropylene and polyethylene fibers with pulp. The filter bag 10 has a bag shape in which one material is folded at the bottom 11 and thermally bonded at the side surface 12. The filter bag 10 has a trapezoidal shape in which the opening 13 side is slightly expanded with respect to the base 11 side. The filter bag 10 contains therein an extraction material 101 such as tea leaves such as black tea, oolong tea, green tea, and barley tea, and roasted and ground coffee beans.
The support 20 is made of, for example, a flexible material such as cardboard or plastic sheet that has been waterproofed with polyethylene or the like. The support 20 is configured such that a horizontally long belt-like mount (substantially rectangular thin plate) is folded and overlapped at the center (described later) and joined on the short side 21 side so as to expand into a ring shape. The developed shape of the support 20 will be described later with reference to FIG.

図2に示すように、支持具20の上側の長辺23側には、濾過袋10の開口部13側が接着されている。尚、濾過袋10の支持具20への取り付け方法は、接着に限定されない。例えば、融着であってもよい。支持具20がポリマー樹脂でラミネートされた紙で構成され、濾過袋10が熱溶融性を有する材料で構成される場合、熱融着によって取り付けられることが好ましい。
濾過袋10の開口部13は、一部が支持具20の上側の相対する2つの長辺23に接着されている。より具体的には、拡開されたときの支持具20の拡開面の幅(後述する台紙の第1の折り目の一例としての第1のミシン目31の長さ)が濾過袋10の接着されない部分の長さとほぼ同じとなるように、濾過袋10の開口部13の接着部分の長さ(接着されない部分の長さ)が決定される。これにより、濾過具1が拡開されたとき、濾過袋10の開口部13を安定的に広く開口できる。
As shown in FIG. 2, the opening 13 side of the filter bag 10 is bonded to the upper long side 23 side of the support tool 20. In addition, the attachment method to the support tool 20 of the filter bag 10 is not limited to adhesion | attachment. For example, fusion may be used. When the support 20 is made of paper laminated with a polymer resin and the filter bag 10 is made of a material having heat melting property, it is preferably attached by heat fusion.
A part of the opening 13 of the filter bag 10 is bonded to two opposing long sides 23 on the upper side of the support 20. More specifically, the width of the expanded surface of the support 20 when expanded (the length of the first perforation 31 as an example of a first fold of the mount to be described later) is the adhesion of the filter bag 10. The length of the bonded portion of the opening 13 of the filter bag 10 (the length of the unbonded portion) is determined so as to be approximately the same as the length of the unbonded portion. Thereby, when the filter 1 is expanded, the opening part 13 of the filtration bag 10 can be stably opened widely.

支持具20(濾過具1)の下側の長辺22は、中央から左右に同じ深さの2つの凹部24,25が形成されている。濾過具1が拡開されて容器100に載置されたとき、この凹部24,25に容器100の上側の縁が入り込んで、濾過具1が容器100に安定的に載置される(図1参照)。
支持具20の中央には孔26が穿かれており、その孔26の下側部分に形成された舌部27にて支持具20と濾過袋10とが接着される。これにより、濾過具1(支持具20)が拡開されたとき、濾過袋10の開口部13だけではなく下方部分も拡開されて、濾過袋10の内部空間を広げる。濾過袋10の開口部から熱湯等の抽出媒体が注入される際、抽出媒体の自重によって濾過袋10の内部空間が狭められることはない。抽出媒体は濾過袋10内で対流し被抽出材101に均等に接触するので、抽出効果を高めることができる。抽出された嗜好性飲料の抽出液は容器100内に流下する(図1参照)。
On the long side 22 on the lower side of the support 20 (filter 1), two concave portions 24 and 25 having the same depth are formed from the center to the left and right. When the filter 1 is expanded and placed on the container 100, the upper edge of the container 100 enters the recesses 24 and 25, and the filter 1 is stably placed on the container 100 (FIG. 1). reference).
A hole 26 is formed in the center of the support tool 20, and the support tool 20 and the filter bag 10 are bonded to each other by a tongue portion 27 formed in a lower portion of the hole 26. Thereby, when the filter 1 (support tool 20) is expanded, not only the opening part 13 but the lower part of the filter bag 10 is expanded, and the internal space of the filter bag 10 is expanded. When an extraction medium such as hot water is injected from the opening of the filtration bag 10, the internal space of the filtration bag 10 is not narrowed by the weight of the extraction medium. Since the extraction medium convects in the filter bag 10 and contacts the material 101 to be extracted evenly, the extraction effect can be enhanced. The extracted extract of the palatable beverage flows down into the container 100 (see FIG. 1).

以上の構成を有する濾過具1を実現するための支持具20の展開図を図3を用いて説明する。
図3は、支持具20の展開図である。
図3に示すように、支持具20は、略長方形状の台紙(薄板)の上側の長辺23から約3分の1の高さの位置に、短辺21を起点として中央に向かって所定の長さの第1の折り目の一例としての第1のミシン目31が形成されている。第1の実施形態では、形状の製作を容易にするため、第1のミシン目31を短辺21に対して垂直に形成している。
A developed view of the support 20 for realizing the filter 1 having the above configuration will be described with reference to FIG.
FIG. 3 is a development view of the support tool 20.
As shown in FIG. 3, the support 20 has a predetermined height from the long side 23 on the upper side of the substantially rectangular mount (thin plate) about one third to the center starting from the short side 21. A first perforation 31 is formed as an example of a first fold having a length of. In the first embodiment, the first perforation 31 is formed perpendicular to the short side 21 in order to facilitate the production of the shape.

第1のミシン目31の端部31aから台紙の第1の長辺の一例としての下側の長辺22まで第2の折り目の一例としての第2のミシン目32が形成され、第1のミシン目31の端部31aから台紙の第2の長辺の一例としての上側の長辺23まで切込み部33が形成されている。端部31aから上側の長辺23までを折り目ではなく切込み部33とすることで、折り曲げ部分を少なくし、拡開作業の負荷を軽減できる。
また、支持具20は、環形状に接合されるために、図3の右側の短辺21に糊代部28が形成されている。ここで、この糊代部28には、拡開面の凹んだ形状(後述)を実現するために、第1のミシン目31に対応する位置に隙間29が形成されている。支持具20を環形状とするために、折返し線で折り返して1箇所の糊代部28で接合するので、支持具20の製造コストを軽減できる。また、隙間29により、拡開時の第1のミシン目31の位置での折り曲げ負荷(拡開作業の負荷)を軽減できる。
A second perforation 32 as an example of the second fold line is formed from the end 31a of the first perforation 31 to the lower long side 22 as an example of the first long side of the mount, A cut portion 33 is formed from the end portion 31a of the perforation 31 to the upper long side 23 as an example of the second long side of the mount. By using the cut portion 33 instead of the fold line from the end portion 31a to the upper long side 23, the bent portion can be reduced and the load of the expansion work can be reduced.
Further, since the support 20 is joined in an annular shape, a margin part 28 is formed on the short side 21 on the right side of FIG. Here, a gap 29 is formed in the glue margin 28 at a position corresponding to the first perforation 31 in order to realize a concave shape (described later) of the spread surface. In order to make the support tool 20 into a ring shape, it is folded back by a folding line and joined at one glue margin 28, so that the manufacturing cost of the support tool 20 can be reduced. Further, the clearance 29 can reduce the bending load (expansion work load) at the position of the first perforation 31 at the time of expansion.

第1のミシン目31の長さは、濾過具1が拡開されたときに形成される拡開面34(図1参照)の幅を決定する。第1のミシン目31の長さは、上述した濾過袋10の接着されない部分の長さや濾過具1が載置される容器100(図1参照)の大きさとの関係から決定される。
第1の実施形態では、第2のミシン目32と切込み部33とは第1のミシン目31の端部31aで連続した円弧を描くように決定されており、第1のミシン目31の端部31aにおける円弧の接線は第1のミシン目31に対して直角に形成されている。これにより、拡開されて形成される拡開面34は、第1のミシン目31の位置で最も幅広となり、濾過具1が拡開した形状を安定的に維持している。
尚、ここでは、1枚の台紙を糊代部28にて環形状に接合して支持具20を構成する例を説明したが、これに限定されるものではない。例えば、同じ形状の2枚の台紙を糊代部にて接合して環形状の支持具20を構成するようにしても良い(図示省略)。拡開されるとき糊代部をバランスよく配置できる。
The length of the 1st perforation 31 determines the width | variety of the expansion surface 34 (refer FIG. 1) formed when the filter 1 is expanded. The length of the first perforation 31 is determined from the relationship between the length of the portion of the filtration bag 10 that is not bonded and the size of the container 100 (see FIG. 1) on which the filter 1 is placed.
In the first embodiment, the second perforation 32 and the notch 33 are determined so as to draw a continuous arc at the end 31 a of the first perforation 31, and the end of the first perforation 31 is determined. A tangent line of the arc in the portion 31 a is formed at a right angle to the first perforation 31. Thereby, the expansion surface 34 formed by being expanded becomes the widest at the position of the first perforation 31, and the shape in which the filter 1 is expanded is stably maintained.
In addition, although the example which joins one board | substrate in the ring shape in the glue margin part 28, and comprised the support tool 20 was demonstrated here, it is not limited to this. For example, two ring-shaped mounts having the same shape may be joined at the margin portion to form the ring-shaped support 20 (not shown). When spread, the adhesive margin can be arranged in a well-balanced manner.

(濾過具の使用方法)
以上に説明した濾過具1の使用方法について以下に説明する。
図4は、濾過具1を拡開する途中の状態を説明するための図である。
図4に示すように、濾過具1の拡開面方向から濾過具1を挟む方向(図の矢印の方向)に指(図示省略)で押すと、支持具20は第1及び第2のミシン目31,32と切込み部33の位置を基準として変形し、濾過具1が拡開される。具体的には、第1のミシン目31が谷折りとなり、第2のミシン目32が山折りとなって変形し、濾過具1が拡開される。
(How to use the filter)
The usage method of the filter 1 demonstrated above is demonstrated below.
FIG. 4 is a view for explaining a state in the middle of expanding the filter 1.
As shown in FIG. 4, when pressing with a finger (not shown) in the direction (in the direction of the arrow) sandwiching the filter 1 from the direction of the expansion surface of the filter 1, the support 20 is the first and second sewing machines. The filter 1 is expanded by deforming with reference to the positions of the eyes 31 and 32 and the notch 33. Specifically, the first perforation 31 is a valley fold, the second perforation 32 is a mountain fold, and the filter 1 is expanded.

上述したように、濾過袋10の下方が支持具20の舌部27に接着されているので、濾過具1(支持具20)の拡開に合わせて濾過袋10は開口される。
拡開面方向から押し続けられて、表側(図4の手前側)の台紙が第2のミシン目32の位置で山折りとなって形成される拡開面と裏側(図4の奥側)の台紙の拡開面とが同一平面(拡開面34)を構成するとき、第1のミシン目31を基準にして上側の拡開面35が外側に倒れる。このとき、第1のミシン目31の位置がリブとして機能し、濾過具1は形状を安定的に維持する(図1に示す状態となる)。
As described above, since the lower portion of the filter bag 10 is bonded to the tongue portion 27 of the support tool 20, the filter bag 10 is opened in accordance with the expansion of the filter tool 1 (support tool 20).
An expanded surface and a back side (back side in FIG. 4) formed by the front side (front side in FIG. 4) being folded in the position of the second perforation 32 while being pushed from the direction of the expanded surface. When the expansion surface of the mount forms the same plane (expansion surface 34), the upper expansion surface 35 falls to the outside with respect to the first perforation 31. At this time, the position of the 1st perforation 31 functions as a rib, and the filter 1 maintains a shape stably (it will be in the state shown in FIG. 1).

このように、濾過具1の短辺を両側から挟むように押すことで、濾過具1は拡開されて形状を安定的に維持することが可能となる。また、折り目をミシン目とすることで、折り曲げ位置を定めることが可能となり、折り曲げ作業(拡開作業)の負荷を軽減できる。
これにより、ユーザは、濾過具1を容器100に載置して、濾過袋10に予め収納された、或いは、開口された後に入れられた被抽出材101に対して、熱湯等の抽出媒体を注ぎ込むことが可能になる。ユーザは煩わされることなく、嗜好性飲料を楽しむことができる。
Thus, by pushing so that the short side of the filter 1 may be pinched | interposed from both sides, the filter 1 can be expanded and it can maintain a shape stably. Further, by making the folds into perforations, it is possible to determine the folding position, and the load of the bending work (expansion work) can be reduced.
Thus, the user places the filter 1 on the container 100 and puts an extraction medium such as hot water on the material to be extracted 101 that is stored in the filter bag 10 in advance or after being opened. It becomes possible to pour. The user can enjoy a palatability drink without bothering.

(第2の実施形態)
図5は、第2の実施形態にかかる濾過具2の斜視図である。図1に示す濾過具1と同一の構成要素は、同一の符号を付すことで説明を省略する。
図5に示すように、濾過具2の支持具40は、切込み部43が第1のミシン目31の端部31aから台紙の上側の長辺23に向かう途中まで形成されている点で、切込み部33が第1のミシン目31の端部31aから台紙の上側の長辺23まで形成された第1の実施形態にかかる濾過具1の支持具20と相違する(図2参照)。上側の長辺23がつながっているので、上側の拡開面35が外側に大きく開いて倒れることがない。よって、熱湯等の抽出媒体を注ぎ込むときに、注ぎ口(図示省略)が上側の拡開面35に引っかかる恐れが少なくなり、使い勝手が向上する。
(Second Embodiment)
FIG. 5 is a perspective view of the filter 2 according to the second embodiment. The same components as those of the filter 1 shown in FIG.
As shown in FIG. 5, the support tool 40 of the filter tool 2 is cut in that the cut portion 43 is formed halfway from the end portion 31 a of the first perforation 31 toward the upper long side 23 of the mount. The part 33 is different from the support tool 20 of the filter tool 1 according to the first embodiment in which the portion 33 is formed from the end 31a of the first perforation 31 to the long side 23 on the upper side of the mount (see FIG. 2). Since the upper long side 23 is connected, the upper expanded surface 35 is not greatly opened outward and falls down. Therefore, when an extraction medium such as hot water is poured, there is less possibility that the spout (not shown) will be caught by the upper expansion surface 35, and usability is improved.

(第3の実施形態)
図6は、第3の実施形態にかかる濾過具3の斜視図である。
図6に示すように、濾過具3の支持具50は、第1のミシン目31の端部31aから下側の長辺22まで形成された第2の折り目の一例としての第2のミシン目52と、端部31aから上側の長辺23まで形成された第3の折り目の一例としての第3のミシン目53とが、直線で形成されている点で、第1及び第2の実施形態にかかる濾過具1,2の支持具20,40と相違する。このとき、端部31aにおいて、第2のミシン目52や第3のミシン目53は第1のミシン目31に対して直角又は鋭角に形成されることが好ましい。第2及び第3のミシン目52,53を直線とすることで支持具50の製作が容易となり、第2又は第3のミシン目52,53を第1のミシン目31に対して直角又は鋭角に形成することで拡開により形成される拡開面34が濾過具3の内側に向かって凹んだ形状となり方形状を安定的に維持する。
(Third embodiment)
FIG. 6 is a perspective view of the filter 3 according to the third embodiment.
As shown in FIG. 6, the support tool 50 of the filter 3 includes a second perforation as an example of a second fold formed from the end 31 a of the first perforation 31 to the lower long side 22. First and second embodiments in that 52 and a third perforation 53 as an example of a third fold formed from the end 31a to the upper long side 23 are formed in a straight line. It differs from the support tools 20 and 40 of the filter tools 1 and 2 concerning. At this time, the second perforation 52 and the third perforation 53 are preferably formed at a right angle or an acute angle with respect to the first perforation 31 at the end 31 a. By making the second and third perforations 52 and 53 straight, the support 50 can be easily manufactured, and the second or third perforations 52 and 53 are perpendicular or acute to the first perforation 31. In this way, the expanded surface 34 formed by the expansion becomes a concave shape toward the inside of the filter 3, and the square shape is stably maintained.

(第4の実施形態)
図7は、第4の実施形態にかかる濾過具4の使用状態を示す斜視図、図8は、濾過具4(図7)の支持具60の展開図、図9は、支持具60(図8)が環形状に接合されるときの接合領域79付近の部分拡大図である。
図7に示すように、濾過具4は、濾過袋10と、濾過袋10を保持する支持具60とを有して構成される。濾過具4は拡開されて、容器100に載置される。濾過具4の支持具60において、第1のミシン目71は谷折りにされ、第2のミシン目72は山折りにされて、支持具60を拡開形状に維持している。このとき、拡開されて形成される拡開面64は、支持具60の内側に向けて凹状に湾曲する。これに対して、第1の切込み部75(図8)から上側の長辺63(図8)までの上縁部65は、支持具60の外側に向けて凸状に湾曲する。
(Fourth embodiment)
FIG. 7 is a perspective view showing a use state of the filter 4 according to the fourth embodiment, FIG. 8 is a development view of the support 60 of the filter 4 (FIG. 7), and FIG. 8) is a partially enlarged view of the vicinity of a joining region 79 when joining in a ring shape.
As shown in FIG. 7, the filtering tool 4 includes a filtering bag 10 and a support tool 60 that holds the filtering bag 10. The filter 4 is expanded and placed on the container 100. In the support tool 60 of the filter 4, the first perforation 71 is valley-folded, and the second perforation 72 is mountain-folded to maintain the support tool 60 in an expanded shape. At this time, the expanded surface 64 formed by expanding is curved concavely toward the inside of the support tool 60. On the other hand, the upper edge portion 65 from the first cut portion 75 (FIG. 8) to the upper long side 63 (FIG. 8) is curved convexly toward the outside of the support tool 60.

以上に説明した濾過具4の形状を実現するための支持具60の展開図を図8を用いて説明する。
図8に示すように、支持具60は、略長方形状の台紙(薄板)の縦方向中央付近のやや上方の位置に、短辺61(又は折返し線70)を起点とする第1のミシン目71が形成されている。第4の実施形態では、図8の中央の第1のミシン目71は、拡開前に短辺61を構成する折返し線70に対称で、下側の長辺62に向かって凸に形成されている。また、第1のミシン目71の端部71aと下側の長辺62との間に、第2のミシン目72が形成されている。第2のミシン目72は、下側の長辺62に向かって凸に(略円弧状に)形成されている。
A developed view of the support 60 for realizing the shape of the filter 4 described above will be described with reference to FIG.
As shown in FIG. 8, the support 60 is a first perforation starting from the short side 61 (or the folding line 70) at a position slightly above the center in the vertical direction of the substantially rectangular mount (thin plate). 71 is formed. In the fourth embodiment, the first perforation 71 in the center of FIG. 8 is symmetrical to the fold line 70 that forms the short side 61 before spreading, and is convex toward the long side 62 on the lower side. ing. Further, a second perforation 72 is formed between the end 71 a of the first perforation 71 and the lower long side 62. The second perforation 72 is formed so as to protrude toward the lower long side 62 (substantially in an arc shape).

上側の長辺63と第1のミシン目71との間に、第1の切込み部75が形成されている。第4の実施形態では、第1の切込み部75は、上側の長辺63に平行に(折返し線70に垂直に)形成されている。また、端部71aと第1の切込み部75との間に、第2の切込み部76が形成されている。第4の実施形態では、端部71a付近の第2の切込み部76は、第1のミシン目71が延長されて形成され、拡開時の端部71a付近の応力を分散している。これにより、ユーザの拡開作業が容易になり、拡開後に台紙の破れを防ぎ、形状が安定する。尚、第1の切込み部75は上側の長辺63に平行でなくても良い。凸状に湾曲する上縁部65(図7)と凹状に湾曲する拡開面64(図7)とが形成されるように、例えば、上側の長辺63に平行ではなく沿って形成されても良い。
支持具60は、図8の右側の短辺61に糊代部68が形成されている。糊代部68は、下側の長辺62に向かって凸の(略円弧状の)外形を有し、被接合部77(後述)に接合されるとき第2のミシン目72を避けている。これにより、糊代部68は、拡開時に第2のミシン目72が山折りされるのを妨げない。糊代部68は、拡開面64(図7)の半幅より更に小さい幅を有して形成されている。
A first cut portion 75 is formed between the upper long side 63 and the first perforation 71. In the fourth embodiment, the first cut portion 75 is formed in parallel to the upper long side 63 (perpendicular to the folding line 70). In addition, a second cut portion 76 is formed between the end portion 71 a and the first cut portion 75. In the fourth embodiment, the second cut portion 76 in the vicinity of the end portion 71a is formed by extending the first perforation 71, and disperses the stress in the vicinity of the end portion 71a during expansion. This facilitates the user's expansion work, prevents the mount from being torn after the expansion, and stabilizes the shape. The first cut portion 75 may not be parallel to the upper long side 63. For example, the upper edge portion 65 (FIG. 7) curved in a convex shape and the widened surface 64 (FIG. 7) curved in a concave shape are formed, for example, along the upper long side 63 instead of in parallel. Also good.
As for the support tool 60, the margin part 68 is formed in the short side 61 of the right side of FIG. The margin portion 68 has an outer shape that is convex (substantially arc-shaped) toward the lower long side 62, and avoids the second perforation 72 when joined to the joined portion 77 (described later). . Thereby, the margin part 68 does not prevent the second perforation 72 from being folded in a mountain at the time of expansion. The margin portion 68 is formed to have a width that is smaller than the half width of the spread surface 64 (FIG. 7).

糊代部68には、第1のミシン目71が折返し線70に対称となるように延長されて形成されている。また、糊代部68には、接合時に第1の切込み部75に対応する位置に隙間69が形成されている。隙間69は、拡開時に対応する第1の切込み75に対して充分な幅を有して形成されている。
支持具60は、図8の左側に、糊代部68が接合される被接合部77が形成されている。被接合部77は、図8の中央に示された拡開面64(図7)の折返し線70の右側部分と同様、第2のミシン目72と第1の切込み部75と第2の切込み部76とを有して構成される。そして、被接合部77は、第2のミシン目72から所定の幅D1の略円弧状の外形線と、糊代部68の隙間69に対して所定の幅D2(図9)の外形線とで構成される逃げ領域78(図8では仮想的に破線の斜線領域として表示した)を中央付近に有する。逃げ領域78は、支持具60が環形状にされるとき、糊代部68に形成された第1のミシン目71に対応する位置となる(後述)。
A first perforation 71 is formed in the glue margin 68 so as to be symmetric with respect to the folding line 70. In addition, a gap 69 is formed in the glue margin 68 at a position corresponding to the first notch 75 at the time of joining. The gap 69 is formed to have a sufficient width with respect to the first cut 75 corresponding to the expansion.
The support 60 is formed with a joined portion 77 to which the adhesive margin portion 68 is joined on the left side of FIG. Similar to the right side portion of the fold line 70 of the expanded surface 64 (FIG. 7) shown in the center of FIG. 8, the joined portion 77 has a second perforation 72, a first cut portion 75, and a second cut. Part 76. The joined portion 77 has a substantially arcuate outline having a predetermined width D 1 from the second perforation 72 and an outline having a predetermined width D 2 (see FIG. 9) with respect to the gap 69 of the glue margin 68. A relief area 78 composed of a line (shown virtually as a dashed hatched area in FIG. 8) is provided near the center. The relief area 78 is a position corresponding to the first perforation 71 formed in the glue margin 68 when the support tool 60 is ring-shaped (described later).

以上に説明した支持具60が環形状に接合されるときの接合領域79付近を図9を用いて説明する。
図9に示すように、第4の実施形態では、支持具60が環形状にされ、短辺61に平行に所定の幅D3だけホットプレスされて、糊代部68と被接合部77とは熱融着される。即ち、糊代部68と被接合部77とは、面全体が接合されない。接合される幅D3は、濾過具4(図7)として使用に耐えられるだけの充分な接合力が得られるよう決定される。
糊代部68は隙間69を挟んで上下に分かれており、被接合部77は第1の切込み部75を挟んで上下に分かれているから、これに対応して接合領域79は上下に分かれる。また、上述の通り、被接合部77には逃げ領域78が形成され、接合される領域は逃げ領域78より幅が狭いので、第1の切込み部75から下の接合領域79は、逃げ領域78を挟んで二つに分かれる。支持具60が環形状にされるとき、糊代部68に形成された第1のミシン目71は逃げ領域78に対応するので、糊代部68と被接合部77との接合の影響を受けることなく、糊代部68の第1のミシン目71は谷折りにできる。よって、第1のミシン目71の位置で谷折りして拡開するので、ユーザは拡開作業を簡易に行うことが可能となる。
The vicinity of the joining region 79 when the support 60 described above is joined in a ring shape will be described with reference to FIG.
As shown in FIG. 9, in the fourth embodiment, the support 60 is formed into an annular shape and hot-pressed by a predetermined width D 3 parallel to the short side 61, Are heat-sealed. In other words, the entire surface of the margin portion 68 and the joined portion 77 are not joined. The width D 3 to be joined is determined so as to obtain a joining force sufficient to withstand use as the filter 4 (FIG. 7).
Since the margin portion 68 is divided into upper and lower portions with a gap 69 therebetween, and the bonded portion 77 is divided into upper and lower portions with the first cut portion 75 interposed therebetween, the bonding region 79 is divided into upper and lower portions corresponding thereto. Further, as described above, the escape region 78 is formed in the joined portion 77, and the region to be joined is narrower than the escape region 78, so the junction region 79 below the first cut portion 75 is the relief region 78. Divided into two parts. When the support tool 60 is ring-shaped, the first perforation 71 formed in the glue margin portion 68 corresponds to the relief region 78, and is therefore affected by the joining of the glue margin portion 68 and the joined portion 77. The first perforation 71 of the margin allowance 68 can be valley-folded. Therefore, since the valley folds and expands at the position of the first perforation 71, the user can easily perform the expansion work.

第1のミシン目71と上側の長辺63との間に第1の切込み部75が形成されている。拡開時、第1の切込み部75の下側に、支持具60の内側に向けて凹状に湾曲した拡開面64(図7)が形成され、支持具60の形状を保つ。第1の切込み部75の上側に、支持具60の外側に向けて凸状に湾曲した上縁部65(図7)が形成される。上方から見るとき、支持具60の上縁部65は楕円形状を形成し、ユーザに良好な美観を提供する。
図3に示す隙間29が第1のミシン目31(図3)に対応する位置に幅狭に形成されているのに対して、第4の実施形態では、隙間69は、拡開時に対応する第1の切込み75に対して充分な幅を有して形成されている。これにより、支持具60が環形状にされるとき、第1の切込み75との厳格な位置合わせを必要としない。
隙間69が充分な幅を有するので、上縁部65(図7)の糊代部68は幅狭になる。その結果、上縁部65(図7)において、接合後の折返し線70の両側で可撓性(剛性)は同程度になる。また、被接合部77に逃げ領域78が形成されて、糊代部68と被接合部77とが接合される側(短辺61の右側)は、短辺61を挟んだ反対側(左側)と可撓性(剛性)がほぼ同じになっている。よって、拡開されたとき、折返し線70の両側で湾曲状態はほぼ同じになる。逃げ領域78は第1のミシン目71の谷折りを妨げない。これにより、支持具60は短辺61を挟んでほぼ均等に拡開され、バランスの取れた形状を有する支持具60を提供できる。形状は安定し、ユーザが容器100(図7)に載置するときの状態が安定する。
A first cut portion 75 is formed between the first perforation 71 and the upper long side 63. At the time of expansion, an expanded surface 64 (FIG. 7) curved concavely toward the inside of the support tool 60 is formed below the first cut portion 75, and the shape of the support tool 60 is maintained. An upper edge portion 65 (FIG. 7) that is curved in a convex shape toward the outside of the support tool 60 is formed on the upper side of the first cut portion 75. When viewed from above, the upper edge 65 of the support 60 forms an oval shape, providing a good aesthetic to the user.
The gap 29 shown in FIG. 3 is narrowly formed at a position corresponding to the first perforation 31 (FIG. 3), whereas in the fourth embodiment, the gap 69 corresponds to the time of expansion. The first notch 75 is formed with a sufficient width. Thereby, when the support tool 60 is made into a ring shape, strict alignment with the first notch 75 is not required.
Since the gap 69 has a sufficient width, the margin portion 68 of the upper edge portion 65 (FIG. 7) becomes narrow. As a result, in the upper edge portion 65 (FIG. 7), the flexibility (rigidity) is almost the same on both sides of the folded line 70 after joining. Further, the escape region 78 is formed in the joined portion 77, and the side where the adhesive margin portion 68 and the joined portion 77 are joined (the right side of the short side 61) is the opposite side (the left side) across the short side 61. The flexibility (rigidity) is almost the same. Therefore, when expanded, the curved state is substantially the same on both sides of the fold line 70. The escape area 78 does not hinder the valley folding of the first perforation 71. Thereby, the support tool 60 can be spread substantially evenly across the short side 61, and the support tool 60 which has a balanced shape can be provided. The shape is stable, and the state when the user places the container 100 (FIG. 7) is stable.
