Description

本発明は、液体などの流動性を有する内容物を密封収納するパウチに関し、使用時には内容物をボトルなどの他の容器に移し替えて使用する詰替え用のパウチに関する。更に詳細には、内容物をボトルなどの口径の小さな容器にも安全かつ容易に移し替えられるように、パウチ上部の一部に狭い幅の注出路部を設けるとともに、注出口部の形状を工夫して開口した注出口を移し替える対象の空容器にスムーズに差込むことの出来る、開口性と操作性の改善されたスタンディングパウチ等の詰替え用パウチに関する。   The present invention relates to a pouch for hermetically storing a fluid content such as a liquid, and to a refill pouch that is used by transferring the content to another container such as a bottle during use. More specifically, in order to safely and easily transfer the contents to bottles and other small-bore containers, a narrow pour-out channel is provided at the top of the pouch and the shape of the pour-out port is devised. In addition, the present invention relates to a refilling pouch such as a standing pouch that can be smoothly inserted into an empty container to be transferred and has improved openability and operability.

従来、液状などの流動性を有する内容物を密封包装する詰替え用容器としては、自立性があり立体容器としての特徴も一部備えているスタンディングパウチが主に採用され、かつ、開封時に内容物を外にこぼすことなく他の容器に安全に移し替えられるよう、パウチ上部の一部に幅を狭くした注出路を形成してその先端近傍で開口して注出口を設ける方法があり、さらには、別に作成したプラスチック成形体などの注出口部品をパウチ上部の一部に熱接着して取り付ける方法などが採られていた。   Conventionally, as a refilling container for hermetically wrapping liquid contents such as liquid, a standing pouch that is self-supporting and has some features as a three-dimensional container has been mainly adopted, and the contents when opened There is a method of forming a pour channel with a narrow width in a part of the upper part of the pouch and opening it near the tip so that it can be safely transferred to another container without spilling outside, For example, a method of attaching a spout part such as a separately formed plastic molding to a part of the upper part of the pouch by heat bonding was employed.

近年、シャンプー・リンスなどの詰替え容器に代表される包装袋は、様々な機能が付与されている為、形状や構成が複雑化している。とりわけ内容物を簡単に素早く詰替えることの出来る包装袋に対する市場要望は高く、注出口付近にプラスチック成形物を熱溶着して注出時の内部空洞を確保したり、真空成形等により注出口付近にエンボス加工と呼ばれる凹凸を設けたり、注出口自身をプラスチック成形物にしたりなどの様々な方法が実施されている。   In recent years, packaging bags typified by refill containers such as shampoos and rinsers have been given various functions and thus have complicated shapes and configurations. In particular, there is a high market demand for packaging bags that can easily and quickly refill the contents. Plastic moldings are thermally welded near the spout to secure an internal cavity during pouring, or near the spout by vacuum molding, etc. Various methods such as embossing, which is called embossing, and the spout itself is made into a plastic molding are being implemented.

しかし、求められる要求が高くなるにつれて製袋時の工程が多く複雑になり、製造コストも高くなることは避けられなかった。更には、プラスチック成形物を溶着する方法では加工の際にピンホールが発生したり、エンボス加工により凹凸を設ける方法では成形時にピンホールが発生したりするなどの異常が起こる場合があり、ピンホール部分からの内容物漏れも報告されている。   However, it has been unavoidable that as the demands are increased, the bag-making process becomes more complicated and the manufacturing cost increases. Furthermore, abnormalities such as pinholes may occur during processing in the method of welding plastic moldings, and pinholes may occur during molding in the method of providing irregularities by embossing. Content leakage from parts has also been reported.

詰替え用のパウチでは上記のような付加的な手法を用いないで液状内容物を簡単に素早く詰替えることが出来るように、パウチ上部の一隅の注出路をカットして開口した注出口からボトル等の他の容器に詰替えるという方法が一般に行われていた(特許文献1、2、3)。   In the refilling pouch, it is possible to refill the liquid contents easily and quickly without using the additional method as described above. The method of refilling with other containers etc. was generally performed (patent document 1, 2, 3).

液状内容物を簡単に素早く詰替えるという点から見ると、この場合の従来のパウチでの問題点は開口した注出口とその回りの形状が詰替え作業の障害になる場合が多いことであり、具体的には、パウチ上部をカットした時にそれに連なっている断片が注出中に内容物に触れて内容物を外にこぼしたりすることがあり、また、開口した注出口が小さい場合は内容物の注出速度が遅く逆に大きい場合には移し替える先のボトル等の開口部にスムーズに入らないためにいらいらするということが問題となっていた。   From the point of view of refilling the liquid contents easily and quickly, the problem with the conventional pouch in this case is that the open spout and the shape around it often obstruct refilling work, Specifically, when the upper part of the pouch is cut, the fragments connected to the pouch may touch the contents during pouring and spill out of the contents, and if the opened spout is small, the contents When the dispensing speed is slow and conversely large, it has been a problem that it is frustrated because it does not smoothly enter the opening of the bottle or the like to be transferred.

パウチ上部の一隅に注出路をカットして注出口を形成する上記の方法でカットした断片が注出中に内容物に触れる問題については、断片を注出口から完全に切り離してゴミとして捨てることで回避することが出来るが、パウチを開口した注出口がボトル等の開口部にスムーズに入らないという問題は詰替え作業を行う人にとってはより深刻な問題となっていた。   Cut the pouring channel at the top corner of the pouch to form the spout.For the problem that the piece cut by the above method touches the contents during pouring, the piece is completely separated from the spout and discarded as garbage. Although it can be avoided, the problem that the spout opening the pouch does not smoothly enter the opening of a bottle or the like has become a more serious problem for those who perform refilling work.

詰替え用パウチがスタンディングパウチの場合、上記の注出口のカット位置は殆どが正面から見て左側上部のコーナーに付いていて開封時のカット開始位置を指示するノッチ(切断開始のための切り欠き)が設けられカット方向を指示する切断誘導線が印刷されているのが普通である。
パウチから内容物をボトルに詰替える際には、切断誘導線端部のノッチから切断誘導線に沿って注出路を横断して直線的にカットして注出口を開口する。次にパウチを持ち上げて左に傾けて開口された注出口の部分をボトルの口に差込んで内容物をボトルに詰替える。
When the refilling pouch is a standing pouch, most of the above-mentioned spout cut positions are attached to the upper left corner when viewed from the front and indicate the cut start position at the time of opening (notch for starting cutting) In general, a cutting guide line indicating the cutting direction is printed.
When refilling the contents from the pouch into a bottle, the outlet is opened by cutting linearly across the extraction path from the notch at the end of the cutting guide line along the cutting guide line. Next, the pouch is lifted and tilted to the left, and the opened spout portion is inserted into the mouth of the bottle to refill the contents with the bottle.

パウチの注出口を切断誘導線よりカットして注出口を開口した時点では、注出口部は閉塞している場合が多く、注出口部の幅が差込まれるボトルの口径より大きくなるとボトルへの差込みが困難となる。   When the pouch spout is cut from the cutting guide line and the spout is opened, the spout portion is often closed, and when the width of the spout portion is larger than the diameter of the inserted bottle, Insertion becomes difficult.

また、ボトルの口径に合わせてパウチの注出口部を狭くすると注出の流量が減少してシャンプーやコンディショナーのような高粘度の液体では注出口部で詰まって注ぎ終わるのに多大な時間を要してしまい、取扱者は詰替えにストレスを感じてしまう。   In addition, if the pouch outlet is narrowed to match the bottle diameter, the flow rate of the pouch is reduced, and for high-viscosity liquids such as shampoos and conditioners, it takes a long time to clog and finish pouring at the outlet. As a result, the handler feels stressful about refilling.

さらに、パウチの注出口を形成するための切断誘導線は印刷に加えて従来はレーザー加工のハーフカット等で直線状に入れていたので、開口後に注出口部分をボトルに差込んだ際に注出口開口部上端内側の輪郭がボトル口径部に当たりやすく差込みがし難いという問題があった(図3(B)および図6参照)。   In addition, the cutting guide line for forming the pouch outlet has been linearly formed by laser cutting half-cut in addition to printing, so when the outlet part is inserted into the bottle after opening, There was a problem that the inner contour of the upper end of the outlet opening easily hits the bottle caliber and is difficult to insert (see FIGS. 3B and 6).

移し替え用のパウチのコーナー部などのパウチの一部を切り取って開口部を形成する方法は簡便ではあるが、内容物の注出が安定しにくく、移し替えの容易性と安全性の点で問題があった。   Although it is simple to cut out a part of the pouch, such as the corner of the transfer pouch, to form the opening, it is difficult to pour out the contents, making transfer easier and safer. There was a problem.

さらに、パウチ上部の一部に幅を狭くした注出路を設けて開封時に開口して注出口を形成する方法では、単にコーナー部を切り取って開口部を形成する方法に比べれば、内容物を他の容器に移し替える際の操作性と安全性は向上するが、開封された注出口の口が開きにくく注出口の開口部の保持性が確保されない場合もあるためボトルへの差し込みや注出の際に不便であり移し替えの容易性の点で問題があった。   Furthermore, in the method of forming a spout by opening a pouch with a narrow width at a part of the upper part of the pouch and opening it at the time of opening, the contents are different from the method of simply cutting off the corner and forming the opening. The operability and safety when transferring to a container are improved, but the opening of the opened spout is difficult to open, and the retainability of the spout opening may not be secured. Inconvenient and sometimes problematic in terms of ease of transfer.

本発明は従来技術の問題に鑑みてその解消を意図してなされたものであり、液状内容物が充填されるパウチにおいて、プラスチック成形物を付設することなく、注出口による内容物の移し替えが容易に出来る詰替え用パウチを提供する事を課題としている。   The present invention has been made in view of the problems of the prior art, and is intended to solve the problem. In a pouch filled with a liquid content, the content can be transferred by the spout without attaching a plastic molded product. The problem is to provide a refillable pouch that can be easily made.

本発明は上記課題を解決するために成されたものであり、請求項1の発明は、対向した表裏2枚のフィルムを周縁シール部にて溶着し、その上部一隅に注出路形成シール部により形成された注出路と注出路の先端部に注出口を設けたパウチであって、

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. The invention of claim 1 is such that two opposed front and back films are welded together at a peripheral seal portion, and a pour-out path forming seal portion is provided at one upper corner thereof. A pouch having a pouring outlet formed at the tip of the pouring path and the pouring path formed,
A cutting guide wire is provided in the vicinity of the tip of the pouring path so as to cross the pouring path, an opening start portion (notch) is provided on the side seal part side of the cutting guiding line, and the other side of the cutting guide line is in the middle of the pouring path The refilling pouch with a spout is characterized in that the cutting guide line is bent downward from a position beyond the spout path.

請求項2の発明は、切断誘導線がパウチの外表面にレーザー加工により設けられたハーフカット線であることを特徴とする請求項1に記載の注出口付き詰替えパウチである。   The invention according to claim 2 is the refillable pouch with a spout according to claim 1, wherein the cutting guide wire is a half-cut wire provided on the outer surface of the pouch by laser processing.

請求項3の発明は、注出路に、断面が外側に凸または内側に凸となるエンボスを設けことを特徴とする請求項1または2に記載の注出口付き詰替えパウチである。   A third aspect of the present invention is the refillable pouch with a spout according to the first or second aspect, characterized in that an embossment whose cross section is convex outward or convex inward is provided in the pouring path.

請求項4の発明は、パウチが底部にガゼット部を設けたスタンディングパウチの形態であることを特徴とする請求項1から3のいずれか1項に記載の注出口付き詰替えパウチである。   The invention according to claim 4 is the refillable pouch with a spout according to any one of claims 1 to 3, wherein the pouch is in the form of a standing pouch having a gusset portion at the bottom.

本発明の請求項1の発明によれば、対向した表裏2枚のフィルムを周縁シール部にて溶着し、その上部一隅に注出路形成シール部により形成された注出路と注出路の先端部に注出口を設けた注出口付き詰替えパウチであって、注出路の先端近傍に切断誘導線を注出路を横断するように設け、切断誘導線の側部シール部側には開封開始部(ノッチ)を設け、切断誘導線の反対側は注出路の途中ないし注出路を越えた位置から切断誘導線が下方に屈曲していることによって、カット後の注出口をボトル等の空容器の口に差込むときにパウチ注出口の内側の角がボトルの口に引っ掛かることが避けられるので、取扱者は安心して容易にパウチの注出口をボトルに差し込むことが出来るのでスムーズに内容物の詰替えを行うことが可能となる。   According to the invention of the first aspect of the present invention, the two facing front and back films are welded at the peripheral seal portion, and the pouring passage formed at the upper corner by the pouring passage forming seal portion and the tip portion of the pouring passage. A refilling pouch with a spout provided with a spout, provided with a cutting guide wire in the vicinity of the tip of the spout passage so as to cross the spout passage, and at the side seal portion side of the cutting guide wire, an opening start portion (notch ) And the other side of the cutting guide wire is bent downward from the middle of the pouring route or from the position beyond the pouring route, so that the spout after cutting is turned into the mouth of an empty container such as a bottle. The inside corner of the pouch spout can be prevented from being caught by the mouth of the bottle when plugging in, so the operator can easily insert the pouch spout into the bottle without worrying about refilling the contents smoothly. Can be done.

また、本発明の注出口付き詰替えパウチでは、ボトル等の口へ差込み易くするためにパウチの注出口の幅を狭くする必要がないので、液体内容物の詰替え時に内容物の流量が減少することもなく高粘度の液体の場合でも詰替え作業にストレスを感じることはなくなる。   In addition, in the refill pouch with a spout of the present invention, it is not necessary to narrow the width of the pouch spout to facilitate insertion into the mouth of a bottle or the like, so the flow rate of the content decreases when refilling the liquid content. In the case of a highly viscous liquid, there is no stress in the refilling operation.

さらに、本発明の注出口付き詰替えパウチでは、プラスチック成型物などによる別個の注出口や開口補強のための治具等をパウチに装着する必要もないので、成形物の注出口等をパウチに取り付けたことによる不具合、たとえば、パウチ自身の形状が複雑になり保管や運搬の手間が増えるだけでなく、使用後の廃棄にあたってもその費用が割高になること等々の成形物起因の不具合は発生しない。これにより、製造コストを大幅に抑えることが可能である。   Furthermore, in the refillable pouch with a spout of the present invention, it is not necessary to attach a separate spout for plastic molding or a jig for reinforcing the opening to the pouch. Defects caused by attachment, for example, the shape of the pouch itself is complicated and not only increases storage and transportation, but also does not cause defects caused by the molded product, such as high costs for disposal after use. . As a result, the manufacturing cost can be significantly reduced.

さらに、本発明の注出口付き詰替えパウチは、パウチの構成材料としては開口部保持の目的でアルミニウム箔を使用する必要が必ずしもないため、詰替え終了後の焼却時の残渣による問題もなく容易に廃棄可能であり、金属探知機による密封後の異物検査も可能である。   Furthermore, the refillable pouch with a spout of the present invention does not necessarily use an aluminum foil as a constituent material of the pouch for the purpose of holding an opening, and thus is easy without problems due to residues during incineration after completion of refilling. In addition, it can be discarded, and foreign matter inspection after sealing with a metal detector is also possible.

また、本発明の注出口付き詰替えパウチは、機械や設備の改造をすることなく従来の設備でレーザー加工によるハーフカットの形状を変更するだけで必要な効果が得られるので製袋時の工程数も従来の注出口付き詰替えパウチと変わらず、大幅なコストアップも発生しない。   In addition, the refilling pouch with a spout of the present invention is a process at the time of bag making because the necessary effect can be obtained simply by changing the shape of the half cut by laser processing with conventional equipment without modifying the machine or equipment. The number is the same as the conventional refilling pouch with a spout, and there is no significant cost increase.

請求項2の発明に係る注出口付き詰替えパウチによれば、切断誘導線がパウチの外表面にレーザー加工により設けられたハーフカット線であることによって、内容物の保存性に影響を及ぼすことなく、湾曲した形状の切断が容易に可能になり、また複数本のハーフカット線を入れることによって湾曲した形状での注出口開口部の形成がより容易で確実になる。   According to the refillable pouch with a spout according to the invention of claim 2, the cutting guide line is a half-cut line provided by laser processing on the outer surface of the pouch, thereby affecting the preservability of the contents. In addition, the curved shape can be easily cut, and the formation of the spout opening in the curved shape is easier and more reliable by inserting a plurality of half-cut lines.

請求項3の発明に係る注出口付き詰替えパウチでは、注出口開口部と注出路の注出中の断面閉塞を防止するために、注出路に、断面が外側に凸または内側に凸となるエンボスを設けている。これにより、パウチの運搬時や内容物封入時および注出口開口時と内容物移し替え時に発生しやすい表裏フィルムの密着による注出口の断面閉塞とそれにより注出に時間がかかる、あるいは注出が途切れてしまう等によって詰替え時間がかかってしまう等の不具合をなくすことが出来る。   In the refilling pouch with a spout according to the invention of claim 3, the cross section of the spout is convex outward or inward in order to prevent cross-section blockage during spout of the spout opening and the spout. Embossing is provided. This makes it possible to block the cross section of the spout due to the close contact of the front and back films, which is likely to occur when transporting the pouch, filling the contents, opening the spout, and transferring the contents. It is possible to eliminate problems such as taking time for refilling due to interruption.

請求項4の発明に係る注出口付き詰替えパウチでは、袋が底部にガゼット部を設けたスタンディングパウチの形態であることから使用時の自立性があるので保管時に置きやすいのみならず詰替え作業のときにパウチが倒れて内容物がこぼれないように使用途中でも一時的に立てて置くことが出来る。   In the refilling pouch with a spout according to the invention of claim 4, since the bag is in the form of a standing pouch with a gusset portion at the bottom, it is self-supporting during use, so it is easy to place during storage and refilling work During the use, the pouch can be placed upright temporarily during use so that the contents will not fall out.

以上のように、本発明の注出口付き詰替えパウチでは、液状内容物が充填されるパウチにおいて、プラスチック成形物を付設することなく、注出口による内容物の移し替えが容易に出来る詰替え用パウチを提供する事が出来る。   As described above, in the refill pouch with the spout of the present invention, the refill can be easily transferred by the spout without attaching a plastic molding in the pouch filled with the liquid content. Pouch can be provided.

すなわち、本発明の注出口付き詰替えパウチを用いることによって、注出口を開封した直後に口が開き、取り扱い者はスムーズにパウチの注出口をボトル等に差し込むことが出来、口が閉塞することがないので安定して容易に内容物を詰替えることが出来る。   That is, by using the refillable pouch with the spout of the present invention, the mouth opens immediately after opening the spout, and the operator can smoothly insert the pouch spout into a bottle or the like, and the mouth is closed. The contents can be refilled stably and easily.

以下に本発明を実施するための形態の一例について、図を参照しながら具体的に説明する。
図1は本発明の注出口付き詰替えパウチの一例の正面から見た概略図である。
Hereinafter, an example of an embodiment for carrying out the present invention will be specifically described with reference to the drawings.
FIG. 1 is a schematic view of an example of a refillable pouch with a spout according to the present invention as seen from the front.

図1に示した概略図では、注出口付き詰替えパウチを構成する表フィルム(2)と裏フィルム(3)の積層体を用いて周知の方法により製袋された自立包装袋の、サイドシール部(10)、底シール部(4)、注出口シール部(7)およびそれによって形成された注出路(6)、内容物封入後にトップシール部となる充填口(33)、開封時の切断誘導線(13)および開封し易くするためのノッチ(14)、を示しており、充填口(33)は内容物充填後にシールされる。   In the schematic shown in FIG. 1, the side seal of the self-supporting packaging bag made by a well-known method using the laminate of the front film (2) and the back film (3) constituting the refillable pouch with a spout Part (10), bottom seal part (4), spout seal part (7) and pour channel (6) formed thereby, filling port (33) which becomes the top seal part after filling the contents, cutting at the time of opening A guide wire (13) and a notch (14) for ease of opening are shown, and the filling port (33) is sealed after filling the contents.

切断誘導線(13)はノッチ(14)から注出路近辺まではほぼ直線でよいが、切断誘導線のノッチの反対側は注出路の途中ないし注出路を越えた位置から下方に屈曲していて切断終点A(36)に至っている。比較のために従来の注出口付き詰替えパウチの場合の直線状の切断誘導線(13)の切断終点B(35)も図に示した。   The cutting guide line (13) may be substantially straight from the notch (14) to the vicinity of the pouring path, but the opposite side of the cutting guide line notch is bent downward from the middle of the pouring path or beyond the pouring path. The cutting end point A (36) is reached. For comparison, the cutting end point B (35) of the linear cutting guide line (13) in the case of a conventional refilling pouch with a spout is also shown in the figure.

さらに図示していないエンボス部(11)と開封時の切断誘導線(13)の近辺にこれに沿った方向でフィルム表面にレーザー加工で付けられた、開封のときの開裂線が曲線に
なるように補助するための、曲率半径Rで切断線終点A(36)に至るハーフカット線は図4の拡大説明図に示した。
Furthermore, the embossed part (11) (not shown) and the cutting guide line (13) at the time of opening are laser-processed on the film surface in the direction along the cutting line so that the tearing line at the time of opening becomes a curve. The half-cut line that reaches the cutting line end point A (36) with the radius of curvature R is shown in the enlarged explanatory view of FIG.

図2は図1に示した本発明の注出口付き詰替えパウチの一例の注出口近辺の拡大説明図である。   FIG. 2 is an enlarged explanatory view of the vicinity of the spout of the example of the refillable pouch with the spout of the present invention shown in FIG.

図2に示した拡大説明図では、注出口の位置をパウチの正面から見て左側上のコーナー部(7)とした場合を示してあるが、以降の説明は注出口の位置がパウチの正面から見て右側上コーナー部である場合も左右対称で同様である。   The enlarged explanatory view shown in FIG. 2 shows the case where the position of the spout is the left upper corner portion (7) when viewed from the front of the pouch. In the following description, the position of the spout is the front of the pouch. The same applies to the upper right corner as viewed from the right and left.

図2では、注出口を形成する切断誘導線(13)の切断開始点はパウチの左サイドシール側のノッチ(14)で切断終点は注出路(6)に関してノッチの反対側のシール右端部の切断終点部A(36)である。   In FIG. 2, the cutting start point of the cutting guide line (13) forming the spout is the notch (14) on the left side seal side of the pouch, and the cutting end point is at the right end of the seal opposite the notch with respect to the pouring path (6). Cutting end point A (36).

注出口の形成の際に、従来はノッチ(14)からシール右端部の切断終点部B(35)までを直線状にカットする切断誘導線に沿ってカットして注出口を形成するが、本発明の注出口付き詰替えパウチにおいては、ノッチ(14)からシール右端部の切断終点部B(35)までを右下がりの曲線形状にカットして右端に角のない注出口を形成する。切断終点部Bとなるシール右端部B(35)までを直線状にカットする場合に形成される開口部内側コーナー部の角となる部分は、切断終点部A(36)までを曲線状にカットすることによって注出口の角の内側コーナー部(37)が除かれて詰替え時にボトルの口に引っ掛かることのない滑らかな注出口とすることが出来る。   When forming the spout, conventionally, the spout is formed by cutting along the cutting guide line that cuts straight from the notch (14) to the cutting end point B (35) at the right end of the seal. In the refilling pouch with the spout of the present invention, the notch (14) to the cut end point B (35) at the right end of the seal are cut into a downwardly curved shape to form a spout without a corner at the right end. When cutting up to the right end of the seal B (35), which is the end point of cutting B, in a straight line, the corner that is the corner of the inner corner of the opening is cut up to the end of cutting A (36) in a curved line By doing so, the inner corner portion (37) of the corner of the spout can be removed, and a smooth spout that does not get caught in the mouth of the bottle at the time of refilling can be obtained.

この曲線状のカットを容易にするためにレーザー加工によるハーフカットをノッチ(14)からシール右端部の切断終点部A(36)まで施し、これを切断誘導線とする。この切断誘導線に沿ってカットすると切断終点部A(36)近くのシール部を斜め下に向けてR形状でカットするのでシール右端部は角がとれて滑らかになる。   In order to make this curvilinear cutting easy, a half cut by laser processing is performed from the notch (14) to the cutting end point A (36) at the right end of the seal, which is used as a cutting guide line. When cutting along the cutting guide line, the seal portion near the cutting end point A (36) is cut in an R shape so as to be inclined downward, so that the right end portion of the seal is rounded and smooth.

図4に示したように、上記のレーザー加工によるハーフカットはパウチの注出方向に略直交する注出路上にレーザー加工によるR形状のハーフカットを複数入れることで可能になる。また、カット性を良くするためにはレーザー加工によるハーフカットは3本を平行に、切断終点部A(36)に向けて収束する形で施すのが望ましい。   As shown in FIG. 4, half cutting by the laser processing described above can be performed by putting a plurality of R-shaped half cuts by laser processing on the extraction path that is substantially orthogonal to the extraction direction of the pouch. Further, in order to improve the cutting performance, it is desirable that the half-cut by laser processing is performed in such a manner that three pieces are parallel and converge toward the cutting end point A (36).

また、上記のレーザー加工によるハーフカットの形状は曲率半径(R)が25mmから50mmであることが望ましい。   Further, it is desirable that the half-cut shape by the laser processing has a curvature radius (R) of 25 mm to 50 mm.

図4には本発明の注出口付き詰替えパウチの注出路に、断面が外側に凸または内側に凸となるエンボス(11)を設けている領域の図を示した。このエンボス(11)は型押しや真空成形等の周知の方法で設けることが出来る。   FIG. 4 shows a diagram of a region in which an embossing (11) whose section is convex outward or convex inward is provided in the extraction path of the refillable pouch with the injection outlet of the present invention. This emboss (11) can be provided by a known method such as embossing or vacuum forming.

図3にはパウチに内容物封入の後に詰替え作業を開始する時の、注出口形成後の注出口近辺の説明図を本発明の注出口付き詰替えパウチの場合(A)と従来の注出口付き詰替えパウチの場合(B)に分けて示した。   FIG. 3 is an explanatory view of the vicinity of the spout after the spout is formed when the refilling operation is started after filling the contents in the pouch. In the case of the refill pouch with a spout of the present invention (A) and the conventional note. In the case of a refillable pouch with an outlet, it is shown separately in (B).

本発明の注出口付き詰替えパウチでは図3(A)に注出部開口部(8)の切り口を示したように注出口部の右側端部に角がないので、開口後パウチを持ち上げて注出口部根元の部分(38)をボトル(39)の口縁に接触させてここを支点としてパウチを左に傾けて注出口部をボトルの口に差し込むときに角がボトルの口に引っ掛かることがなくスムーズに差込むことが可能になる(図6参照)。   In the refilling pouch with the spout of the present invention, the right end of the spout has no corners as shown in FIG. 3A, and the pouch after the opening is lifted. When the base of the spout part (38) is brought into contact with the mouth edge of the bottle (39) and the pouch is tilted to the left with this point as a fulcrum, the corner is caught in the mouth of the bottle. It becomes possible to insert smoothly (see FIG. 6).

これに対して、注出口のカットを直線状に行う従来の注出口付き詰替えパウチの場合では図3(B)に注出口開口部(8)の切り口を示したように注出口部の右側端部が角になるので、パウチを持ち上げて注出口部根元(38)の部分をボトル(39)の口縁に接触させてここを支点としてパウチを左に傾けて注出口部をボトルの口に差し込むときにこの注出口角(37)がボトルの口に引っ掛かってしまうということが起こる。   On the other hand, in the case of a conventional refilling pouch with a spout that cuts the spout in a straight line, the right side of the spout is as shown in FIG. 3B. Since the end becomes a corner, the pouch is lifted and the base of the spout part (38) is brought into contact with the mouth edge of the bottle (39). When inserting into the bottle, this spout angle (37) is caught in the mouth of the bottle.
