Description

本発明は液体調味料、液体化粧料、液体洗剤などの詰め替え用の液体を収容する用途に用いられ、詰め替えに際しての作業性を向上させる包装袋に関するものである。 The present invention relates to a packaging bag that is used for storing refillable liquids such as liquid seasonings, liquid cosmetics, and liquid detergents, and improves workability during refilling.

従来から詰め替え用の液体を収容する包装袋においては、柔軟なフィルムからなる袋があり、袋上部の一隅を注出路部とするとともに、その先端部分を注出口部とし、切断にて注出口を開いた注出口部を相手容器の差し込むなどして収容されている液体を移し替えることができるようにしたパウチタイプや、スタンディングパウチタイプの袋が多く流通している。 Conventionally, packaging bags that store liquids for refilling include bags made of flexible film, with one corner of the upper part of the bag as the pouring path and the tip of the bag as the spout, and the spout is cut by cutting. There are many pouch-type and standing pouch-type bags in the market that allow the liquid contained in the container to be transferred by inserting the opening spout into the mating container.

また昨今においては、スタンディングタイプの包装袋であって、袋胴部の袋前面にこの袋胴部と分岐した状態で注出路部を備える構造の包装袋が提案されている。そして、注出路部なとどする分岐部分を袋胴部と同一のフィルムで形成する方法としては、袋前面のフィルムを袋上部側の位置で前方に折り出すようにして分岐部分を形成したり、特許文献１や特許文献２に示されているように、袋上部からのフィルムと袋下部からのフィルムとのそれぞれを延長して、袋上部からのフィルムの延長部分と袋下部からのフィルムを分岐の位置で折り返しながら延長した延長部分とを重ね合わせて、前記分岐部分としての注出路部を形成する方法があった。 Further, in recent years, a packaging bag which is a standing type packaging bag and has a structure in which a pouring path portion is provided on the front surface of the bag body portion in a state of being branched from the bag body portion has been proposed. Then, as a method of forming the branch portion to be traced to the pouring path portion with the same film as the bag body portion, the branch portion is formed by folding the film on the front surface of the bag forward at the position on the upper side of the bag. , As shown in Patent Document 1 and Patent Document 2, the film from the upper part of the bag and the film from the lower part of the bag are extended, respectively, and the extended portion of the film from the upper part of the bag and the film from the lower part of the bag are extended. There has been a method of forming an injection path portion as the branch portion by superimposing the extended portion that is folded back at the branch position.

特許第４６１７８６６号公報Japanese Patent No. 4617866 特開２００５−０８８８９４号公報Japanese Unexamined Patent Publication No. 2005-088894

上述した袋胴部から注出路部を分岐している包装袋では、袋胴部自体の収容容積を損なわずに注出路部を流れる部分の長さを確保し易いことから、収容物を注ぎ出しているときの流れを安定させることができる。 In the packaging bag in which the pouring path is branched from the bag body as described above, it is easy to secure the length of the portion flowing through the pouring path without impairing the accommodating volume of the bag itself. It is possible to stabilize the flow when it is being used.

一方でこの包装袋では、最初に収容物を注出するときには、注出路部の先端の注出口部を切断して注出口を開いてから注出路部を上方に引き起こしたり、或いは注出路部を上方に引っ張って起こしながら、注出口部を切断する作業が必要になる。このように未開封の場合、この包装袋から収容物を最初に注ぎ出すまでに二工程の作業が必要であって、収容物を注ぎ出すまでの作業が煩雑であるという問題があった。 On the other hand, in this packaging bag, when the contents are first poured out, the spouting port at the tip of the pouring path is cut to open the spout and then the pouring path is raised upward, or the pouring path is opened. It is necessary to cut the spout while pulling it upward to raise it. As described above, in the case of unopened, there is a problem that two steps are required to first pour out the contents from the packaging bag, and the work to pour out the contents is complicated.

そこで本発明は上記事情に鑑み、袋胴部の袋前面に注出路部を分岐させている包装袋において、注出口部の引き起こしと、注出口部の切断による注出口の形成、即ち開封とが連続した作業で行えるようにすることを課題とし、この包装袋において、開封して最初に収容物を注ぎ出すための作業を簡単な作業にすることを目的とするものである。 Therefore, in view of the above circumstances, in the packaging bag in which the pouring path portion is branched on the front surface of the bag of the bag body, the spouting port is raised and the spouting port is formed by cutting the spouting port, that is, the opening is performed. The object is to enable continuous work, and the purpose of this packaging bag is to simplify the work of opening and first pouring out the contents.

（請求項１の発明の効果）
請求項１の発明によれば、袋胴部から分岐している注出路部の張り出し方向の前方に、指先差し入れ孔部を有する引き起こし片が設けられているので、引き起こし片に指先を掛けて上方に引っ張ることで、注出路部が袋高さ方向上方に向けて起きるようになる。 (Effect of the invention of claim 1)
According to the invention of claim 1, since a raising piece having a fingertip insertion hole is provided in front of the ejection path portion branching from the bag body in the overhanging direction, the raising piece is hung on the raising piece and upward. By pulling to, the pouring path will rise upward in the bag height direction.

さらに引き起こし片の外周縁が注出口部の開封予定線の位置に連続しているので、この引き起こし片で注出路部を起こしている状態から続けて注出口部を切断する動作に連続して移ることができ、開封までの作業が一工程となってスムーズなものとなるという効果を奏する。 Furthermore, since the outer peripheral edge of the raised piece is continuous with the position of the planned opening line of the spout, the operation of cutting the spout continuously from the state where the spouting path is raised by this raised piece is continuously performed. This has the effect that the work up to opening becomes a single process and becomes smooth.

また容器への収容物の詰め替えを行なうにあたって、注出路部を袋上下方向上方に向けて引っ張ることで注出路部が起き上がり、注出口部を切断することで収容量に影響を及ぼすことなしに立体的で開口面積の大きい注出口を得ることができるようになる。 In addition, when refilling the container, the pouring path is pulled upward in the vertical direction of the bag to raise the pouring path, and the spout is cut to form a three-dimensional structure without affecting the capacity. It will be possible to obtain a spout with a large opening area.

また注出口部を上方に向けた状態での切断となるので、注出口から収容物が漏れたり飛び散ることを防止できる。 Further, since the cutting is performed with the spout portion facing upward, it is possible to prevent the contained material from leaking or scattering from the spout.

そして注出路部自体をロート状に先細りする形にすることも可能であり、容器の口部に差し込み易く、収容物を最後まで安定した状態で注出できて迅速に収容物の注ぎ出しを行なうことができる注出路部を備えるものとすることができる。また、構造が簡単であることから、袋製造に際して複雑な加工を必要とせず、低コストにて製造することができるという効果を奏する。
また、袋胴部の袋前面から注出路部が分岐した先行技術の包装袋にあっては、注出路部が袋胴部の真上に立ち上がるように起きて注出口が開封されると、注出路部でのフィルム同士が密着し、注出路部の収容物通路が塞がる状態になる場合がある。
この点に対して、請求項１の発明によれば、袋胴部の左右（辺部側）の注出路部通路形成手段の間となる部分あっては、注出路部の引き上げに抗する部分とならないため、分岐前面フィルムと分岐後面フィルムの非ヒートシール領域を含めて袋前面と袋後面での注出路部通路形成手段の間となるフィルムに、折り返し線の方向に交差して外方に折り出る山折り部分が生じるようになり、これによって注出路部の分岐前面フィルムと分岐後面フィルムとの間が開いて通路が形成され、注出路部を収容物がスムーズに流れるようになる。 It is also possible to taper the pouring path itself into a funnel shape, and it is easy to insert it into the mouth of the container, and the contents can be poured out in a stable state until the end, and the contents can be quickly poured out. It can be provided with a pouring path that can be provided. Further, since the structure is simple, there is an effect that the bag can be manufactured at low cost without requiring complicated processing.
In addition, in the case of the packaging bag of the prior art in which the pouring path is branched from the front of the bag of the bag body, when the pouring path rises directly above the bag body and the spout is opened, Note The films at the outlet may come into close contact with each other, and the container passage at the outlet may be blocked.
With respect to this point, according to the invention of claim 1, there is a portion between the left and right (side side) of the bag body portion between the injection path portion passage forming means, which is a portion that resists the pulling up of the injection path portion. Therefore, the film that is between the injection path passage forming means on the front surface of the bag and the rear surface of the bag, including the non-heat-sealed area of the branch front film and the branch rear film, intersects the direction of the folding line and goes outward. A mountain fold portion that folds out is generated, which opens a gap between the branch front film and the branch rear film of the injection path portion to form a passage, so that the contents can flow smoothly through the injection path portion.

（請求項２の発明の効果）
請求項２の発明によれば、袋胴部から分岐している注出路部の辺部に分断可能に配されている引き起こし片は、上記発明と同様に指先差し入れ孔部を有しているので、この引き起こし片に指先を掛けて上方に引っ張ることで、注出路部が袋高さ方向上方に向けて起きるようになる。 (Effect of the invention of claim 2)
According to the invention of claim 2, since the raising piece distributably arranged on the side portion of the pouring path portion branching from the bag body portion has a fingertip insertion hole portion as in the above invention. By hanging the fingertip on this raising piece and pulling it upward, the pouring path portion rises upward in the bag height direction.

そして注出路部の辺部と引き起こし片との間の分断線が注出口部の開封予定線の位置に連続しているので、この引き起こし片で注出路部を起こしている状態から続けて注出口部を切断する動作に連続して移ることができ、開封までの作業が一工程となってスムーズなものとなるという効果を奏する。 And since the dividing line between the side of the pouring path and the raising piece is continuous at the position of the planned opening line of the spouting piece, the spouting port is continued from the state where the pouring path is raised by this raising piece. It is possible to continuously move to the operation of cutting the part, and the work up to opening becomes one step and becomes smooth.

また上記請求項１の発明と同様に、容器への収容物の詰め替えを行なうにあたって、注出路部を袋上下方向上方に向けて引っ張ることで注出路部が起き上がり、注出口部を切断することで収容量に影響を及ぼすことなしに立体的で開口面積の大きい注出口を得ることができるようになる。 Further, as in the invention of claim 1, when refilling the contents in the container, the pouring path portion is raised by pulling the pouring path portion upward in the vertical direction of the bag, and the pouring port portion is cut. It becomes possible to obtain a three-dimensional spout with a large opening area without affecting the capacity.

そして注出路部自体をロート状に先細りする形にすることも可能であり、容器の口部に差し込み易く、収容物を最後まで安定した状態で注出できて迅速に収容物の注ぎ出しを行なうことができる注出路部を備えるものとすることができる。また、構造が簡単であることから、袋製造に際して複雑な加工を必要とせず、低コストにて製造することができるという効果を奏する。
また、袋胴部の袋前面から注出路部が分岐した先行技術の包装袋にあっては、注出路部が袋胴部の真上に立ち上がるように起きて注出口が開封されると、注出路部でのフィルム同士が密着し、注出路部の収容物通路が塞がる状態になる場合がある。
この点に対して、請求項２の発明によれば、袋胴部の左右（辺部側）の注出路部通路形成手段の間となる部分あっては、注出路部の引き上げに抗する部分とならないため、分岐前面フィルムと分岐後面フィルムの非ヒートシール領域を含めて袋前面と袋後面での注出路部通路形成手段の間となるフィルムに、折り返し線の方向に交差して外方に折り出る山折り部分が生じるようになり、これによって注出路部の分岐前面フィルムと分岐後面フィルムとの間が開いて通路が形成され、注出路部を収容物がスムーズに流れるようになる。 It is also possible to taper the pouring path itself into a funnel shape, and it is easy to insert it into the mouth of the container, and the contents can be poured out in a stable state until the end, and the contents can be quickly poured out. It can be provided with a pouring path that can be provided. Further, since the structure is simple, there is an effect that the bag can be manufactured at low cost without requiring complicated processing.
In addition, in the case of the packaging bag of the prior art in which the pouring path is branched from the front of the bag of the bag body, when the pouring path rises directly above the bag body and the spout is opened, Note The films at the outlet may come into close contact with each other, and the container passage at the outlet may be blocked.
With respect to this point, according to the invention of claim 2, the portion between the left and right (side side) of the bag body portion and the means for forming the injection path portion passage is a portion that resists the pulling up of the injection path portion. Therefore, the film that is between the injection path passage forming means on the front surface of the bag and the rear surface of the bag, including the non-heat-sealed area of the branch front film and the branch rear film, intersects the direction of the folding line and goes outward. A mountain fold portion that folds out is generated, which opens a gap between the branch front film and the branch rear film of the injection path portion to form a passage, so that the contents can flow smoothly through the injection path portion.

The pouring path portion 9 has a substantially tapered shape that tapers downward in the vertical center line direction (XX-ray direction) of the bag, and the closed pouring outlet portion 10 is a portion of the overhanging tip.

袋前面２は、袋上部８側のフィルム１１と袋下部６側のフィルム１２とからなるもので、図２の断面で示されているように、前記フィルム１１、１２により、注出路部９を有する状態で袋前面２が形成されている。 The bag front surface 2 is composed of a film 11 on the bag upper portion 8 side and a film 12 on the bag lower portion 6 side, and as shown in the cross section of FIG. 2, the pouring path portion 9 is formed by the films 11 and 12. The front surface 2 of the bag is formed while holding the bag.

袋上部８側のフィルム１１にあっては、注出路部９が分岐している高さ位置Ａから袋下方に延長されている部分を有し、袋下部６側の前記フィルム１２にあっては、注出路部９が分岐している高さ位置Ａから折り返されて袋下方に延長されている部分を有している。 The film 11 on the upper 8 side of the bag has a portion extending downward from the height position A where the pouring path 9 branches, and the film 12 on the lower 6 side of the bag has a portion. , The pouring path portion 9 has a portion that is folded back from the branching height position A and extends downward of the bag.

フィルム１１は上記延長部分を分岐前面フィルム１３として有し、フィルム１２は上記延長部分を分岐後面フィルム１４として有している。そして前記分岐前面フィルム１３と分岐後面フィルム１４とが重ね合わされ、袋左右（袋幅方向）にある側方辺部１５の位置、及び張り出し先端にあって前記側方辺部１５に連続する先端辺部１６の位置で、分岐前面フィルム１３と分岐後面フィルム１４とがヒートシールされている。 The film 11 has the extension portion as the branched front surface film 13, and the film 12 has the extension portion as the branched rear surface film 14. Then, the branched front film 13 and the branched rear film 14 are overlapped with each other, and the positions of the side side portions 15 on the left and right sides of the bag (in the bag width direction) and the tip side at the overhanging tip and continuous with the side side portions 15. At the position of the portion 16, the branched front film 13 and the branched rear film 14 are heat-sealed.

注出路部９の張り出し先端である注出口部１０が上記先端辺部１６の位置でのヒートシールによって閉じられている。そしてこの第一の実施例では、先端辺部１６のヒートシール部分が、注出路部９の張り出し方向前方（袋下方）に向けて延長されて略円板状に拡大され、この拡大部分を引き起こし片１７にしている。 The spout portion 10, which is the overhanging tip of the spouting path portion 9, is closed by a heat seal at the position of the tip side portion 16. Then, in this first embodiment, the heat-sealed portion of the tip side portion 16 is extended toward the front (lower side of the bag) in the overhanging direction of the injection path portion 9 and is enlarged in a substantially disk shape, causing this enlarged portion. It is made into one piece 17.

（引き起こし片）
注出路部９の張り出し方向にこの注出路部９自体がテーパー状に先細していて、上記引き起こし片１７は上述したように注出路部９の張り出し方向の前方、即ち、注出口部１０の張り出し方向の前方の部分であって上記先端辺部１６を拡大した部分に設けられている。この引き起こし片１７も分岐前面フィルム１３と分岐後面フィルム１４とがヒートシールにて重ね合わされている部分であって、ある程度の強度を有する。 (Cause piece)
The dispensing path 9 itself is tapered in a tapered shape in the overhanging direction of the pouring path 9, and the raising piece 17 is in front of the pouring direction of the pouring 9 as described above, that is, the spouting port 10 is overhanging. It is provided in a portion in front of the direction in which the tip side portion 16 is enlarged. The raising piece 17 is also a portion where the branched front film 13 and the branched rear film 14 are overlapped by a heat seal, and has a certain degree of strength.

そして引き起こし片１７は、注出路部９を袋胴部５から袋上下方向上方側に向けて起こすときに用いられるものであり、略円板状としたこの引き起こし片１７に、注出口部１０の領域に重ならないようにして一つの指先差し込み孔部１８が設けられている。 The raising piece 17 is used when the pouring path portion 9 is raised from the bag body portion 5 toward the upper side in the vertical direction of the bag. One fingertip insertion hole 18 is provided so as not to overlap the region.

（指先差し込み孔部）
指先差し込み孔部１８は、分岐前面フィルム１３と分岐後面フィルム１４とを貫くようにして引き起こし片１７に略Ｃ字状に切り込みを入れて、この切り込みによって形成されたフラップにて開放可能に閉じられている透孔形成部分１８ａであり、指先を通す前には閉じた状態とされている。 (Fingertip insertion hole)
The fingertip insertion hole 18 is raised so as to penetrate the branch front film 13 and the branch rear film 14, and a substantially C-shaped notch is made in the piece 17, and the flap formed by this notch closes the fingertip insertion hole 18 so as to be openable. It is a through-hole forming portion 18a that is closed before passing through a fingertip.

注出路部９を上方に引き上げるときには、透孔形成部分１８ａに指先を当てて前記フラップを倒し込み、指先差し込み孔部１８にその指先を掛けるようにして差し込み、指先を差し込んだ状態で引き起こし片１７を袋上下方向上方に向けて引っ張ることで、注出路部９が袋胴部５の袋前面２から前記上方に向けて起きるようにしている。 When pulling up the injection path portion 9, the flap is pushed down by putting a fingertip on the through-hole forming portion 18a, and the flap is inserted so as to hang the fingertip on the fingertip insertion hole portion 18, and the piece 17 is raised with the fingertip inserted. Is pulled upward in the vertical direction of the bag so that the pouring path portion 9 rises upward from the front surface 2 of the bag of the bag body portion 5.

（指先差し込み孔部の大きさ、形状等）
指先差し込み孔部１８は指先が掛かって引き起こし片１７の上方への引き上げが確実に行えるものであればよく、大きさや形状が限定されているものではないが、例えば直径が約１０ｍｍ〜約３０ｍｍとなる円形としたり、長軸が約１０ｍｍ〜約３０ｍｍで短軸が長軸の長さより短かい楕円形とすることが良好である。 (Size, shape, etc. of fingertip insertion hole)
The fingertip insertion hole 18 may be any as long as it can be raised by the fingertip and can be reliably pulled upward, and the size and shape are not limited. For example, the diameter is about 10 mm to about 30 mm. It is preferable to make an elliptical shape having a long axis of about 10 mm to about 30 mm and a short axis shorter than the length of the long axis.

上記指先差し込み孔部１８については、切り込み形成されたフラップにより開け閉め可能に閉じられている透孔形成部分１８ａとして図示しているが、この図示の例に限定されるものではない。指先差し込み孔部１８は、引き起こし片１７の分岐前面フィルム１３と分岐後面フィルム１４とを貫通する透孔であってもよい。透孔である場合の指先差し込み孔部１８の大きさや形状も、例えば直径が約１０ｍｍ〜約３０ｍｍとなる円形としたり、長軸が約１０ｍｍ〜約３０ｍｍで短軸が長軸の長さより短かい楕円形とすることが良好であり、この点は指先差し込み孔部１８を透孔形成部分１８ａとする上記の例と同様である。 The fingertip insertion hole portion 18 is shown as a through-hole forming portion 18a that can be opened and closed by a flap formed by a notch, but the present invention is not limited to this illustrated example. The fingertip insertion hole portion 18 may be a through hole that penetrates the branch front surface film 13 and the branch rear surface film 14 of the raising piece 17. The size and shape of the fingertip insertion hole 18 in the case of a through hole may be, for example, a circle having a diameter of about 10 mm to about 30 mm, or a major axis of about 10 mm to about 30 mm and a minor axis shorter than the length of the major axis. It is preferable to have an elliptical shape, and this point is the same as the above example in which the fingertip insertion hole portion 18 is used as the through hole forming portion 18a.

（開封予定線）
注出口部１０には、この注出口部１０の張り出し方向に交差するようにして開封予定線１９が設けられている。そして図示されているように引き起こし片１７の外周縁２０が、上記開封予定線１９の位置に連続している。 (Scheduled opening line)
The spout portion 10 is provided with a planned opening line 19 so as to intersect the spout portion 10 in the overhanging direction. Then, as shown in the drawing, the outer peripheral edge 20 of the raised piece 17 is continuous with the position of the planned opening line 19.

そして引き起こし片１７を袋上下方向上方に向けて引いて注出路部９を袋前面２から離れるように起こし、さらに注出路部９が袋上下方向上方に向けて起きてからも引き起こし片１７を引き続けることにより、開封予定線１９における引き起こし片１７の外周縁が達している箇所から切れ目が発生して、裂けが開封予定線１９に進んで注出口部１０を切断して注出口を開かせることができるようにしている。 Then, the raising piece 17 is pulled upward in the vertical direction of the bag to raise the pouring path portion 9 away from the front surface 2 of the bag, and even after the pouring path portion 9 is raised upward in the vertical direction of the bag, the raising piece 17 is pulled. By continuing, a cut is generated from the part where the outer peripheral edge of the raising piece 17 reaches the scheduled opening line 19, the tear proceeds to the scheduled opening line 19, the spout portion 10 is cut, and the spout is opened. I am trying to do it.

このように指先差し込み孔部１８に指先を掛けながら引き起こし片１７を上方に引っ張ることで、注出路部９の起こし作業と注出口部１０の切断作業とが連続して開封がスムーズに行えるものとなる。 By pulling the raising piece 17 upward while hanging the fingertip on the fingertip insertion hole portion 18 in this way, the raising work of the pouring path portion 9 and the cutting work of the pouring outlet portion 10 can be continuously opened smoothly. Become.

開封予定線１９は、注出口部１０の分岐前面フィルム１３と分岐後面フィルム１４とにレーザー照射するハーフカット加工を施した線状部分とすることが良好であり、このハーフカット加工によって易開封性を向上させることができる。 It is preferable that the planned opening line 19 is a linear portion in which the branch front film 13 and the branch rear film 14 of the spout portion 10 are subjected to a half-cut process of irradiating the laser, and the half-cut process makes it easy to open. Can be improved.

また注出路部９のヒートシール部分に及ぶ開封予定線１９の両端部には、切り込みを施してノッチ２１が設けられており、この切り込みによっても易開封性が向上されており、指先差し込み孔部１８に指先を掛けながら引き起こし片１７を袋上下方向上方に向けて引いたときに、注出口部１０の切断がより一層スムーズになるようにしている。 Further, notches 21 are provided at both ends of the planned opening line 19 extending to the heat-sealed portion of the pouring path portion 9, and the easy-opening property is also improved by these notches, and the fingertip insertion hole portion. When the piece 17 is pulled upward in the vertical direction of the bag while being raised while hanging the fingertip on 18, the spout portion 10 is cut even more smoothly.

（注出路部通路形成手段）
上記第一の実施例では注出路部９が張り出し方向前方に向けてテーパー状に先細りしていて、この注出路部９の分岐前面フィルム１３と分岐後面フィルム１４とが相対して形成される通路２２も張り出し方向前方に向けてテーパー状に先細りした形状である。そして注出口部１０を切断して注出口が得られるときに、前記分岐前面フィルム１３と分岐後面フィルム１４とが離れた状態となって通路２２が閉塞しないように図られている。 (Means for forming a passage in the pouring path)
In the first embodiment, the injection path portion 9 is tapered toward the front in the overhanging direction, and the branch front film 13 and the branch rear film 14 of the ejection path 9 are formed so as to face each other. 22 also has a shape that tapers toward the front in the overhanging direction. Then, when the spout portion 10 is cut to obtain the spout, the branch front film 13 and the branch rear film 14 are separated from each other so that the passage 22 is not blocked.

そしてこの第一の実施例では、注出路部９の分岐前面フィルム１３と分岐後面フィルム１４とを離れた状態にして通路２２を閉塞させないようにするための注出路部通路形成手段２３が、袋胴部５から注出路部９が分岐する分岐の高さ位置Ａでの左右辺部側に設けられていて、分岐前面フィルム１３における分岐の高さ位置での左右辺部側の部分それぞれを直接、袋後面のフィルム２４にヒートシールして、引き起こし片１７を上方に引っ張る作業を行なっても、注出路部９の左右の辺部側が開かないようにしている。 Then, in this first embodiment, the pouring path portion passage forming means 23 for keeping the branch front film 13 and the branch rear surface film 14 of the pouring path portion 9 apart from each other so as not to block the passage 22 is a bag. It is provided on the left and right side portions at the branch height position A where the pouring path portion 9 branches from the body portion 5, and each of the left and right side portions at the branch height position on the branch front film 13 is directly provided. Even if the film 24 on the back surface of the bag is heat-sealed to pull the raising piece 17 upward, the left and right side portions of the pouring path portion 9 are prevented from opening.

具体的には、注出路部９の上記側方辺部１５となるヒートシール領域２５それぞれは、注出路部９の先細り部位に対応する湾曲部分から袋幅方向側方に向けて延びて袋辺部７まで達しているとともに、袋辺部７側での分岐の高さ位置Ａを跨ぐようにして袋上部８側にかかるように設けられている。また上述したように分岐の高さ位置Ａで袋下部側のフィルム１２が折り返されて上記分岐後面フィルム１４が延長されていて、この折り返し部分の端部それぞれにおいて、折り返し部分（分岐の高さ位置Ａに対応する箇所）の谷折り線を跨ぐようにしてフィルムを除去したフィルム除去部２６が設けられている。 Specifically, each of the heat-sealed regions 25, which is the lateral side portion 15 of the pouring path portion 9, extends from the curved portion corresponding to the tapered portion of the pouring path portion 9 toward the side in the bag width direction and is a bag side. It is provided so as to reach the portion 7 and to straddle the height position A of the branch on the bag side portion 7 side so as to cover the bag upper portion 8 side. Further, as described above, the film 12 on the lower side of the bag is folded back at the branch height position A to extend the branch rear surface film 14, and at each end of the folded portion, the folded portion (branch height position) is formed. A film removing portion 26 is provided in which the film is removed so as to straddle the valley fold line of the portion (corresponding to A).

そして、分岐前面フィルム１３と袋後面３のフィルム２４との間に上記フィルム除去部２６を位置させた状態でヒートシールすることによって、分岐前面フィルム１３が袋後面３のフィルム２４に直接ヒートシールされて上記注出路部通路形成手段２３が形成されている。 Then, the branched front film 13 is directly heat-sealed to the film 24 on the back surface of the bag 3 by heat-sealing the film removing portion 26 between the branch front film 13 and the film 24 on the back surface 3 of the bag. The above-mentioned injection path portion passage forming means 23 is formed.

このように袋胴部５での分岐の高さ位置Ａでの左右の袋辺部７側にそれぞれ注出路部通路形成手段２３が設けられているので、指先差し込み孔部１８に指先を掛けて引き起こし片１７を上方に引いて注出路部９を上方に起きるように引き上げると、このとき前記注出路部通路形成手段２３の部分自体は分岐前面フィルム１３と袋後面３のフィルム２４とが離れずに、この分岐前面フィルム１３と袋後面３のフィルム２４との間が開かないように注出路部９の引き上げに対して抗する部分となる。 As described above, since the pouring path portion passage forming means 23 is provided on each of the left and right bag side portions 7 at the branch height position A in the bag body portion 5, the fingertip is hung on the fingertip insertion hole portion 18. When the raising piece 17 is pulled upward and the pouring path portion 9 is pulled up so as to rise upward, at this time, the branch front film 13 and the film 24 of the bag rear surface 3 are not separated from each other in the pouring path portion passage forming means 23 itself. In addition, it is a portion that resists the pulling up of the pouring path portion 9 so that the space between the branch front film 13 and the film 24 on the back surface 3 of the bag is not opened.

一方、この注出路部通路形成手段２３の間となる部分にあっては、袋前面２のフィルム１２（袋下部６側）から分岐後面フィルム１４が単に折り返されているだけであるため、分岐後面フィルム１４の上方への開きを抑えるような注出路部９の引き上げに対して抗する部分とならない。 On the other hand, in the portion between the pouring path portion passage forming means 23, the branch rear surface film 14 is simply folded back from the film 12 (bag lower portion 6 side) of the bag front surface 2, and therefore the branch rear surface. It does not serve as a portion that resists the pulling up of the injection path portion 9 that suppresses the upward opening of the film 14.

そして注出路部９での分岐前面フィルム１３と分岐後面フィルム１４との非ヒートシール領域を含めて、袋前面２と袋後面３での左右の注出路部通路形成手段２３の間となるフィルムの部分に、谷折り線の方向に交差して外方に折り出る山折り部分が生じるようになる。 Then, including the non-heat-sealed region between the branched front film 13 and the branched rear film 14 at the pouring path portion 9, the film between the left and right pouring path passage forming means 23 at the bag front surface 2 and the bag rear surface 3 In the part, a mountain fold part that intersects in the direction of the valley fold line and folds outward will occur.

この山折りが、注出路部９の通路２２における分岐前面フィルム１３と分岐後面フィルム１４とに張り出し方向に通ることとなる。よって注出路部９の分岐前面フィルム１３と分岐後面フィルム１４との間が開いて通路２２が形成され、注出路部９を収容物がスムーズに流れるようになる。（図３） This mountain fold passes through the branch front film 13 and the branch rear film 14 in the passage 22 of the injection path portion 9 in the overhanging direction. Therefore, the gap between the branch front film 13 and the branch rear film 14 of the pouring path portion 9 is opened to form a passage 22, so that the contents can smoothly flow through the pouring path portion 9. (Fig. 3)

（第二の実施例）
上記包装袋１では、注出路部９を袋胴部５から袋上下方向上方に起こす引き起こし片１７をその注出路部９の張り出し方向前方に配した略円板状のものとし、引き起こし片１７が一つの指先差し込み孔部１８を有しているものとして説明したが、これに限定されるものではなく、引き起こし片１７の構成と、指先差し込み孔部１８の位置、個数を変更することが可能である。引き起こし片１７の構成と、指先差し込み孔部１８の位置、個数が変更されている例を第二の実施例として以下に説明する。 (Second Example)
In the packaging bag 1, the raising piece 17 that raises the pouring path portion 9 upward from the bag body portion 5 in the vertical direction of the bag is formed into a substantially disk shape in which the pouring piece 17 is arranged in front of the pouring path portion 9 in the projecting direction, and the raising piece 17 is formed. Although it has been described as having one fingertip insertion hole portion 18, the present invention is not limited to this, and the configuration of the raising piece 17 and the position and number of the fingertip insertion hole portions 18 can be changed. be. An example in which the configuration of the raising piece 17 and the position and number of the fingertip insertion holes 18 are changed will be described below as a second embodiment.

図４は第二の実施例の包装袋１を袋前面側から見た平面を示していて、第一の実施例の図１と同様に収容物が未充填で扁平な状態を表している。上述したように第一の実施例と第二の実施例とは引き起こし片１７の構成、指先差し込み孔部１８の位置と数が相違している。 FIG. 4 shows a flat surface of the packaging bag 1 of the second embodiment as viewed from the front side of the bag, and shows an unfilled and flat state of the contents as in FIG. 1 of the first embodiment. As described above, the configuration of the raising piece 17 and the position and number of the fingertip insertion holes 18 are different between the first embodiment and the second embodiment.

包装袋１において、図４に示されているように袋上部８側のフィルム１１を分岐の高さ位置Ａから袋下方に向けて延長した分岐前面フィルム１３と、袋下部６側のフィルム１２を同じく分岐の高さ位置Ａで折り返して袋下部６側に延長した分岐後面フィルム１４とは、共に袋上下方向の長さが、袋幅方向に亘って同じとされていて、この分岐前面フィルム１３と分岐後面フィルム１４とが重なっている領域の平面の形状が矩形となっている。 In the packaging bag 1, as shown in FIG. 4, the branch front film 13 in which the film 11 on the upper 8 side of the bag is extended from the height position A of the branch toward the lower side of the bag and the film 12 on the lower 6 side of the bag are formed. Similarly, the branch rear surface film 14 which is folded back at the branch height position A and extended to the bag lower portion 6 side has the same length in the bag vertical direction over the bag width direction, and the branch front film 13 The shape of the plane of the region where the branch rear film 14 and the branch rear film 14 overlap is rectangular.

（引き起こし片）
上記分岐前面フィルム１３と分岐フィルム１４とを重ねた領域中に、上記第一の実施例と同様に、袋胴部５の縦中心線（Ｘ−Ｘ線）が通る位置で下方に向けてテーパー状に先細りした注出路部９が、分岐の高さ位置Ａから設けられているとともに、前記領域中での注出路部９を除いた部分を引き起こし片１７として設けられている。即ち、第一の実施例では引き起こし片を、注出路部の張り出し方向の前方であって略円板状としているが、第二の実施例では袋幅方向に亘る大きさの引き起こし片を備えている。 (Cause piece)
Similar to the first embodiment, the bag body portion 5 is tapered downward at a position where the vertical center line (XX line) passes through the region where the branched front film 13 and the branched film 14 are overlapped. The pouring path portion 9 tapered in a shape is provided from the height position A of the branch, and is provided as a raised piece 17 by raising a portion of the region excluding the pouring path portion 9. That is, in the first embodiment, the raising piece is in front of the overhanging direction of the pouring path portion and has a substantially disk shape, but in the second embodiment, the raising piece having a size extending in the bag width direction is provided. There is.

（分断線）
そして注出路部９の先細りする箇所に対応する湾曲部分から袋胴部５の左右の袋辺部７に延びて上記注出路部通路形成手段２３を含む側方辺部１５に対し、引き起こし片１７は、連続または不連続の分断線２７を介して分離可能に連接されている。なお、前記分断線２７自体は分岐前面フィルム１３と分岐後面フィルム１４とを貫く切り込みである。また分断線２７それぞれは、第一の実施例と同じように注出口部１０の開封予定線１９の位置に連続している。 (Breaking line)
Then, the raising piece 17 extends from the curved portion corresponding to the tapered portion of the pouring path portion 9 to the left and right bag side portions 7 of the bag body portion 5 with respect to the side side portion 15 including the pouring path portion passage forming means 23. Are separably connected via a continuous or discontinuous dividing line 27. The dividing line 27 itself is a notch that penetrates the branched front film 13 and the branched rear film 14. Further, each of the dividing lines 27 is continuous at the position of the planned opening line 19 of the spout portion 10 as in the first embodiment.

第二の実施例において、引き起こし片１７の分岐前面フィルム１３と分岐後面フィルム１４とは重ね合わされた状態で全体的にヒートシールされており、注出口部１０の先端を閉じる先端辺部１６が、この引き起こし片１７の領域中で独立して形成されてはいない。勿論、上記側方辺部１５と連続する状態にしながら引き起こし片１７の領域中に独立して存在するようにしてもよい。 In the second embodiment, the branched front film 13 of the raising piece 17 and the branched rear film 14 are heat-sealed as a whole in a state of being overlapped with each other, and the tip side portion 16 that closes the tip of the spout portion 10 is formed. It is not formed independently in the region of this cause piece 17. Of course, it may be made to exist independently in the region of the raising piece 17 while being continuous with the side side portion 15.

（指先差し入れ孔部）
また指先差し込み孔部１８は、注出口部１０の前方（張り出し方向前方）には配置されていない。この指先差し込み孔部１８は、引き起こし片１７での注出口部１０の前方部分を間にして左右に一つずつ対称にして配置されており、袋上下方向では注出口部１０の前方となる位置の高さに揃う配置としている。 (Fingertip insertion hole)
Further, the fingertip insertion hole portion 18 is not arranged in front of the spout portion 10 (front in the overhanging direction). The fingertip insertion hole portion 18 is symmetrically arranged one by one on the left and right sides of the raising piece 17 with the front portion of the spout portion 10 in between, and is positioned in front of the spout portion 10 in the vertical direction of the bag. It is arranged so that it is aligned with the height of.

図示した第二の実施例における指先差し込み孔部１８それぞれは、袋下部側を連続部分としながら環状の切り込みを入れてフラップにより開閉可能に覆われた透孔形成部分１８ａからなるものとしており、図示の第一の実施例と同様である。そして、指先差し入れ孔部１８自体は大きさ、形状は限定されるものではなく、一例として良好な大きさ、形状は第一の実施例で説明したものと同じである。さらに指先差し入れ孔部１８が透孔とすることが可能である点も第一の実施例での説明と同じである。 Each of the fingertip insertion hole portions 18 in the illustrated second embodiment is composed of a through-hole forming portion 18a covered with a flap so as to be openable and closable by making an annular notch while making the lower part of the bag a continuous portion. It is the same as the first embodiment of. The size and shape of the fingertip insertion hole 18 itself are not limited, and as an example, a good size and shape are the same as those described in the first embodiment. Further, the point that the fingertip insertion hole portion 18 can be a through hole is the same as the description in the first embodiment.

また指先差し入れ孔部１８は、注出口部１０の前方となる位置の高さに揃う配置である必要は必ずしもなく、また左右の何れか一つのみとすることも可能である。 Further, the fingertip insertion hole portion 18 does not necessarily have to be arranged so as to be aligned with the height of the position in front of the spout portion 10, and it is also possible to have only one of the left and right portions.

この第二の実施例の包装袋１においても、引き起こし片１７を上記指先差し込み孔部１８に指先を掛けながら上方に引っ張ることで、引き起こし片１７での先端辺部１６につながった状態で注出路部９が起き上がり、引き起こし片１７を引き続けることで、また引き続けながらひねるなどすることで、開封予定線１９の端部側から切れが生じて注出口部１０が切断され、開封されることとなる。（図６） Also in the packaging bag 1 of the second embodiment, the raising piece 17 is pulled upward while hanging the fingertip on the fingertip insertion hole portion 18, so that the raising piece 17 is connected to the tip side portion 16 of the raising piece 17 and is connected to the pouring path. By raising the portion 9 and continuing to pull the raised piece 17, or by twisting while continuing to pull it, a cut occurs from the end side of the planned opening line 19, and the spout portion 10 is cut and opened. Become. (Fig. 6)

なお、分断線２７が図４に示すように不連続な線とされている場合、引き起こし片１７を引き上げるときに側方辺部１５と細幅で連続している箇所が切断するように設けられている。さらに、分断線２７の袋胴部５における左右の袋辺部７の位置にあっては、引き起こし片１７を引き上げていない状態でこの引き起こし片１７の側辺の折り返し側がめくれるなどして他の物品に引っかかるなどしないように、分断線２７の端部が左右の袋辺部７の端縁までには達しておらず、側方辺部１５への細幅の連続部分が存在する。この連続部分も引き起こし片１７の引き上げをするときに切断されることになる。 When the dividing line 27 is a discontinuous line as shown in FIG. 4, it is provided so that a narrow continuous portion with the side side portion 15 is cut when the raising piece 17 is pulled up. ing. Further, at the positions of the left and right bag side portions 7 on the bag body portion 5 of the dividing line 27, other articles such as the folded side of the side side of the raising piece 17 being turned over in a state where the raising piece 17 is not pulled up. The end portion of the dividing line 27 does not reach the edge of the left and right bag side portions 7 so as not to be caught in the side portion 15, and there is a narrow continuous portion to the side side portion 15. This continuous portion is also caused and will be cut when the piece 17 is pulled up.

なお、分断線自体はレーザー照射するハーフカット加工を施してなるものとすることも可能である。 It is also possible that the dividing line itself is subjected to a half-cut process of irradiating with a laser.
