Description

本発明は、注出補助部材およびその注出補助部材を袋の注出口部に貼着した注出口部付き袋に関し、更に詳しくは、袋の注出口部に貼着することにより、注出口部の開口性とその保形性を向上させ、また、注出口部の折れ曲がりなどによる閉塞を防止し、袋に充填された内容物の注出を容易にできる注出補助部材を袋の注出口部に貼着して内容物の注出適性を向上させた注出口部付き袋に関する。
The present invention relates to a pour-out auxiliary member and a pouch with a pour-out portion in which the pour-out auxiliary member is stuck to a pour-out portion of a bag, and more specifically, by sticking to a pour-out portion of a bag. The pour-out part of the bag improves the opening and shape retention of the bag, prevents the blockage of the pour-out part from being bent, and makes it easy to pour out the contents filled in the bag. It is related with the bag with a spout part which adhered to the inside and improved the pouring ability of the contents.

従来、液状などの流動性を有する内容物を密封包装し、内容物を使用する際に、ボトルなどの他の容器に移し替えて使用するような詰め替え用の容器としては、内容物の他の容器への移し替えを容易に且つ安全に行えると同時に、安価で空容器が嵩張らず使用後の廃棄処理なども容易に行えることが望ましく、簡単なものでは、例えば、積層フィルムをヒートシールして形成した平袋や自立袋などの袋の周縁の一部に、外周をヒートシールしてなる狭い幅の注出口部を設けた袋が使用されてきた。
しかし、このような注出口部付き袋は、安価で生産性に優れる点では好ましいが、注出口部の開口性や開口部の保形性が悪く、内容物注出の途中などで注出口部が閉塞しやすく、内容物の注出適性の点では劣る問題があった。
Conventionally, as a container for refilling that is used by sealing and wrapping liquid contents such as liquid and transferring the contents to other containers such as bottles when using the contents, other contents It is desirable that the transfer to the container can be performed easily and safely, and at the same time, it is desirable that the empty container is not bulky and can be easily disposed of after use, etc. A bag having a narrow spout portion formed by heat-sealing the outer periphery has been used on a part of the periphery of a bag such as a formed flat bag or a self-supporting bag.
However, such a bag with a spout portion is preferable in terms of low cost and excellent productivity, but the spout portion and the shape retaining property of the spout portion are poor, and the spout portion is in the middle of pouring the contents. However, there was a problem that the contents were poorly sealed.

このような問題を解決するために種々改善策が研究され、注出口部の開口性や開口部の保形性など、内容物の注出適性を改善した袋が提案されている。
具体例として、例えば、(1)袋の注出口部のフィルム材料に流路を形成するための溝状の窪みを設け、その溝状の窪みにプラスチック製などの小管を固定して、流路が潰れるのを防止すると共に、前記小管を通して中味を空にできるようにした袋がある(特許文献1参照)。
また、(2)パウチの上部の一部に注出口部を設け、その注出口部の内面に、装着時は偏平な形状で、使用時に筒状に起こして注出口部を開口できる補強部材を装着した詰め替え用パウチがある(特許文献2参照)。
特開平5−132069号公報(第2頁〜第3頁、図1) 特開平11−79195号公報(第2頁〜第7頁、図1、図3)
In order to solve such a problem, various improvement measures have been studied, and a bag with improved contents pouring aptitude such as the opening property of the spout part and the shape retaining property of the opening part has been proposed.
As a specific example, for example, (1) a groove-like depression for forming a flow path is provided in the film material of the spout portion of the bag, and a small tube made of plastic or the like is fixed to the groove-shaped depression, and the flow path There is a bag which prevents the crushing and allows the contents to be emptied through the small tube (see Patent Document 1).
Also, (2) a pour-out part is provided in a part of the upper part of the pouch, and a reinforcing member is formed on the inner surface of the pour-out part so that it has a flat shape when mounted and can be raised in a cylindrical shape when used to open the spout part There is a refillable pouch attached (see Patent Document 2).
JP-A-5-132069 (pages 2 to 3, FIG. 1) Japanese Patent Laid-Open No. 11-79195 (pages 2 to 7, FIGS. 1 and 3)

前記(1)に記載された発明の袋によれば、注出口部のフィルム材料に、流路として溝状の窪みを設け、その窪みにプラスチックの成形体などによる小管を固定しているので、小管は硬さがあり、確実に流路が潰されるのを防止できると共に、その小管を通して袋に充填された内容物を注出することができる。
しかし、このような袋でも、その製造の際、注出口部のフィルム材料に深絞り成形などで溝状の窪みを設け、その中に前記小管を挿入してスポット溶接などで固定しているので、製造の工程数が増し、製造装置が複雑になると同時に生産速度も抑制される。また、前記小管は、円筒状で硬さがあり、その外径が5mm程度以上は必要となるため、袋の注出口部のみが嵩張り、空袋の取り扱いや保管が厄介になるほか、内容物を充填する際の充填シール機における空袋の供給装置についても特別な装置が必要となり、全体として設備費の増大と生産速度の抑制などコストアップの要因が多く、更に品質面においても小管が硬いため、その端部で袋のフィルム材料が傷つけられやすいという問題があった。
According to the bag of the invention described in the above (1), a groove-like depression is provided as a flow path in the film material of the spout portion, and a small tube such as a plastic molded body is fixed to the depression. The small tube is hard and can reliably prevent the passage from being crushed, and the contents filled in the bag can be poured out through the small tube.
However, even in such a bag, since the film material of the spout portion is provided with a groove-like depression by deep drawing or the like, and the small pipe is inserted therein and fixed by spot welding or the like. The number of manufacturing steps increases, the manufacturing apparatus becomes complicated, and at the same time the production speed is suppressed. In addition, the small tube is cylindrical and hard, and its outer diameter is required to be about 5 mm or more, so that only the bag spout is bulky, making it difficult to handle and store empty bags. A special device is also required for the empty bag supply device in the filling and sealing machine when filling things, and there are many factors that increase costs such as an increase in equipment costs and a reduction in production speed as a whole. Since it was hard, there was a problem that the film material of the bag was easily damaged at the end.

また、前記(2)に記載された発明の詰め替え用パウチによれば、パウチの上部の一部に注出口部を設け、その注出口部の内面に、装着時は偏平な形状で、使用時に筒状に起こして注出口部を開口できる補強部材を装着しているので、その補強部材を、プラスチック等の剛性シートを用いて、図3のA−1、B−1、C−1に示したように加工することにより、この状態では偏平であり、この補強部材を注出口部の内面に所定の部分で貼着しておいて、使用時に、例えば両側から中心部に向けて押圧することにより、それぞれ図3のA−2、B−2、C−2に示したように角形に起こされ、注出口部を保形性よく角筒状に開口させることのできる詰め替え用パウチとすることができる。
しかし、このような詰め替え用パウチでも、製造後、保存日数が数カ月以上の長期になると、徐々に補強部材の起こしトルクが高くなり、使用時に注出口部を角筒状に起こしにくくなる問題があり、必ずしも満足できるものではなかった。
Further, according to the refillable pouch of the invention described in (2) above, a spout part is provided in a part of the upper part of the pouch, and the inner surface of the spout part has a flat shape at the time of mounting. Since a reinforcing member that can be raised in a cylindrical shape to open the spout portion is attached, the reinforcing member is shown in A-1, B-1, and C-1 in FIG. 3 using a rigid sheet such as plastic. In this state, the reinforcing member is flat in this state, and the reinforcing member is stuck to the inner surface of the spout portion at a predetermined portion and, for example, pressed from both sides toward the center portion during use. As shown in FIGS. 3A-2, B-2, and C-2, the pouch for refilling is formed in a square shape and can open the spout portion into a rectangular tube shape with good shape retention. Can do.
However, even with such a refillable pouch, if the storage period is longer than several months after manufacture, the raising torque of the reinforcing member gradually increases, and there is a problem that it becomes difficult to raise the spout portion into a rectangular tube shape during use. It was not always satisfactory.

本発明は、このような問題点を解決するためになされたものであり、その課題は、液状などの流動性を有する内容物を密封包装し、内容物を使用する際には、ボトルなどの他の容器に移し替えて使用される注出口部付き袋の分野において、袋の注出口部に貼着することにより、特に注出口部を嵩張らせることがなく、注出口部の開口性とその保形性を経時的にも安定して向上させることができ、また、注出口部の折れ曲がりなどによる閉塞も防止でき、袋に充填された内容物の注出を確実に容易にできる注出補助部材と、その注出補助部材を袋の注出口部に貼着して内容物の注出適性を向上させた注出口部付き袋を生産性よく提供することである。   The present invention has been made in order to solve such problems, and the problem is that when the contents having fluidity such as liquid are sealed and used, the contents such as bottles are used. In the field of bags with spout parts that are used by transferring to other containers, sticking to the spout part of the bag does not make the spout part particularly bulky, and the openability of the spout part and its Dispensing assistance that can stably improve shape retention over time and can prevent clogging due to bending of the spout, etc., and can easily dispense the contents filled in the bag.

本発明において、前記のような注出補助部材は、長尺の巻き取り状に作製しておいて、袋の注出口部に貼着する際に、巻き取りから引き出しながら必要な長さに切断して貼着することが好ましい。このような方法を採ることにより、袋の製袋とインラインで注出補助部材を袋の注出口部に貼着することができるので、注出補助部材が貼着された注出口部付き袋を生産性よく製造することができる。
注出補助部材を袋の注出口部に貼着する方法は、ホットメルト接着剤などの接着剤を用いて貼着することもできるが、ヒートシール方式などの熱接着方式で貼着することが接着の安定性および生産性の両面で優れる点で一層好ましい。
また、注出補助部材は、特に限定はされないが、異形押し出し成形法などにより生産性よく製造することができる。その場合、前記テープ基材と凸条の全体を単一の樹脂で形成してもよいが、例えば、テープ基材を2層以上の多層で形成することがより好ましい。
In the present invention, the above-described extraction assisting member is prepared in a long winding shape, and when sticking to the spout portion of the bag, it is cut to a required length while being pulled out from the winding. It is preferable to stick it. By adopting such a method, the extraction assisting member can be attached in-line with the bag making of the bag to the spout outlet portion of the bag. It can be manufactured with high productivity.
The method of sticking the dispensing auxiliary member to the spout part of the bag can be stuck using an adhesive such as a hot melt adhesive, but it can be stuck by a heat bonding method such as a heat seal method. This is more preferable in terms of excellent adhesion stability and productivity.
Further, the pouring auxiliary member is not particularly limited, but can be manufactured with high productivity by a modified extrusion molding method or the like. In that case, although the tape base material and the entire protrusion may be formed of a single resin, for example, it is more preferable that the tape base material is formed of two or more layers.

特に、注出補助部材を熱接着方式で袋の注出口部に貼着する場合には、注出補助部材の袋の注出口部に熱接着される側の面、即ち、前記テープ基材の凸条を設けていない側の面を袋の注出口部に熱接着可能な樹脂の層で形成し、その反対側の面、即ち、前記テープ基材の凸条を設けた側の面を前記熱接着可能な樹脂よりも融点の高い樹脂の層で形成することにより、一層高い温度での熱接着が可能となるので、袋の注出口部への注出補助部材の貼着速度を高めることができる。
注出補助部材のテープ基材と凸条の全体を単一の樹脂で形成し、熱接着方式で袋の注出口部に貼着する場合、その樹脂としては、袋の貼着面(通常はシーラント層)の材質に応じて、それに熱接着可能な樹脂を選定するが、例えば、低密度ポリエチレン、直鎖状低密度ポリエチレン、中密度ポリエチレン、高密度ポリエチレン、ポリプロピレンのほか、エチレン共重合体やプロピレン共重合体などを使用することができる。
これらのうち、中密度ポリエチレン、高密度ポリエチレン、ポリプロピレン、プロピレン共重合体を用いた場合は、耐熱性に優れているので、注出口部付き袋に内容物を密封した後、レトルト処理を施すような用途にも使用することができる。
また、前記テープ基材を2層以上の多層で形成する場合の具体例として、2層で形成する場合は、例えば、袋の注出口部に熱接着される側の面を低密度ポリエチレンの層で形成し、もう一方の面を中密度ポリエチレンの層で形成することができる。また、3層で形成する場合は、例えば、袋の注出口部に熱接着される側の面を低密度ポリエチレンの層で形成し、その反対側の面をポリプロピレンの層で形成し、中間層は両者の接着性を向上させるプロピレン共重合体などの接着性樹脂の層で形成することができる。
また、テープ基材を多層で形成することにより、注出補助部材を前記品質管理の目的で着色する場合でも、いずれか一層を着色すればよいので全層を着色するよりもコストアップを抑制することができる。着色する色は、光学的に検知できる色であれば特に限定はされないが、青色、赤色などを好適に使用することができる。
In particular, when sticking the pouring auxiliary member to the bag spout portion by the thermal bonding method, the surface of the pouring auxiliary member that is thermally bonded to the spout portion of the bag, that is, the tape base material The surface on which the ridges are not provided is formed of a resin layer that can be thermally bonded to the spout portion of the bag, and the opposite surface, that is, the surface on which the ridges of the tape base material are provided is the surface. By forming the resin layer with a higher melting point than the heat-bondable resin, it becomes possible to heat-bond at a higher temperature, thus increasing the sticking speed of the pouring auxiliary member to the bag spout. Can do.
When the entire tape base and ridges of the dispensing auxiliary member are made of a single resin and are attached to the bag outlet by the thermal bonding method, the resin is attached to the bag (usually, Depending on the material of the sealant layer, a resin that can be thermally bonded is selected. For example, low density polyethylene, linear low density polyethylene, medium density polyethylene, high density polyethylene, polypropylene, ethylene copolymer, A propylene copolymer or the like can be used.
Among these, when medium density polyethylene, high density polyethylene, polypropylene, and propylene copolymer are used, they are excellent in heat resistance, so that the contents are sealed in a bag with a spout portion and then retort-treated. It can be used for various purposes.
Further, as a specific example of the case where the tape base material is formed of two or more layers, in the case where the tape base material is formed of two layers, for example, the surface to be thermally bonded to the spout part of the bag is a low-density polyethylene layer. And the other side can be formed of a layer of medium density polyethylene. In the case of forming with three layers, for example, the surface to be thermally bonded to the spout portion of the bag is formed with a low-density polyethylene layer, and the opposite surface is formed with a polypropylene layer. Can be formed of a layer of an adhesive resin such as a propylene copolymer that improves the adhesion between the two.
In addition, by forming the tape base material in multiple layers, even if the dispensing auxiliary member is colored for the purpose of quality control, it is only necessary to color any one layer, so the cost increase is suppressed compared to coloring all layers. be able to. The color to be colored is not particularly limited as long as it is an optically detectable color, but blue, red, and the like can be suitably used.

次に、図7は、本発明の注出補助部材を袋の注出口部に貼着した注出口部付き袋の第1の実施例の構成を示す模式平面図である。
図7に示した注出口部付き袋100は、前後の壁面フィルム(積層フィルム)1、1′の上下左右四方の端縁部を、上部シール部8と下部シール部13、および側部シール部6a 、6b でヒートシールしてなる四方シール形式の袋において、下部シール部13は内容物の充填口とするため内容物の充填前は未シールの開口部とすると共に、上部の一方のコーナー部(図において左側のコーナー部)を内容物の注出口部10として、その開封位置にハーフカット線11とその両側の端部にノッチ12a 、12b を設け、更に、注出口部10の壁面フィルム1、1′の内側の面に、その中心線Cに沿って、前記開封位置のハーフカット線11から袋100の中心部に向けて、注出補助部材50を注出補助部材貼着部55a 、55b に示すようなパターンで貼着して構成したものである。
尚、上記注出補助部材50としては、前記図1〜図6に示した構成の注出補助部材50a 〜50f のうち、いずれの構成の注出補助部材を用いてもよい。
また、注出補助部材50を注出口部10の壁面フィルム1、1′の内側の面に貼着する際の貼着パターンは、例えば、図1〜図6に示した注出補助部材50a 〜50f の構成においてテープ基材51の略全面で貼着してもよいが、図7の注出補助部材貼着部55a 、55b に示すように、注出口部10の開封位置、即ち、ハーフカット線11に近い部分を除いた領域で、且つ、2本の帯状に分割して貼着することが更に好ましい。
これは注出補助部材をそのテープ基材51の略全面で貼着すると、例えば、注出補助部材50の貼着位置が注出口部10の先端側にずれて、注出補助部材50とハーフカット線11とが交差した場合、ハーフカット線11による開封が注出補助部材50に邪魔されて開封できなくなるが、ハーフカット線11に近い部分を除いた領域で貼着することにより、注出補助部材50の貼着位置が注出口部10の先端側にずれて、注出補助部材50とハーフカット線11とが交差したとしても、数mm程度であれば問題なくハーフカット線11で引き裂いて注出口部10を開封できるためである。また、注出補助部材50の貼着パターンを注出補助部材貼着部55a 、55b のように2本の帯状に分割することにより、注出補助部材のテープ基材51に、その流れ方向の中心線に沿って、前記筋押しによる折り曲げ線53や薄肉部による折り曲げ線54を設けた場合でも、その折り曲げ効果が損なわれることがなくなる。
Next, FIG. 7 is a schematic plan view showing the configuration of the first example of the bag with the spout port portion in which the spout auxiliary member of the present invention is attached to the spout port portion of the bag.
The bag 100 with a spout part shown in FIG. 7 includes upper and lower seal parts 13 and 13 and side seal parts at the edge parts of the front and rear wall films (laminated films) 1, 1 ′. In the four-side sealed bag formed by heat sealing at 6a and 6b, the lower seal portion 13 is used as a filling port for the contents, so that it is an unsealed opening before filling the contents and one upper corner portion. (The left corner in the figure) is the content outlet 10, the half cut line 11 is provided at the opening position, and notches 12 a, 12 b are provided at both ends, and the wall film 1 of the outlet 10 is further provided. 1 'on the inner surface along the center line C from the half-cut line 11 at the unsealing position toward the center of the bag 100, the dispensing assisting member adhering portion 55a, Putter as shown in 55b In is constructed by stuck.

In the configuration of 50f, the tape base material 51 may be attached to almost the entire surface. However, as shown in the extraction auxiliary member attachment portions 55a and 55b in FIG. It is more preferable to divide and paste into two strips in a region excluding the portion close to the line 11.
For example, when the pouring auxiliary member is attached to substantially the entire surface of the tape base 51, for example, the sticking position of the pouring auxiliary member 50 is shifted to the distal end side of the pouring port 10, and the pouring auxiliary member 50 and the half of the pouring auxiliary member 50 are half. When the cut line 11 intersects, the opening by the half cut line 11 is obstructed by the extraction assisting member 50 and cannot be opened, but by sticking in the region excluding the part close to the half cut line 11 Even if the sticking position of the auxiliary member 50 is shifted to the distal end side of the spout part 10 and the pouring auxiliary member 50 and the half-cut line 11 intersect each other, the half-cut line 11 is torn without any problem if it is about several mm. This is because the spout 10 can be opened. Moreover, by dividing the sticking pattern of the pouring auxiliary member 50 into two strips like the pouring auxiliary member sticking portions 55a and 55b, the tape base material 51 of the pouring auxiliary member is arranged in the flow direction. Even when the folding line 53 by the muscle push or the folding line 54 by the thin portion is provided along the center line, the bending effect is not impaired.

図11の(イ)は、注出口部10の両面の壁面フィルム1、1′のうち、片面の壁面フィルム1に外側に膨らむエンボス部Sを設け、その内側に前記図4に示した構成の注出補助部材50d を挿入して貼着した例を示す図である。
この場合、図示したA−A線の断面部では、注出補助部材50d は、壁面フィルム1の内側の面に貼着されておらず、エンボス部Sの内部に収納された状態である。
このように注出口部付き袋300a 〔図10の(イ)参照〕の注出口部10に注出補助部材50d を貼着することにより、注出口部10の両面の壁面フィルム1、1′の間には注出補助部材50d により確実に空隙部が形成されるので、袋300a に充填された内容物を注出する際、注出口部10の先端部をハーフカット線11に沿って開封することにより、自動的に注出口部10が開口し、次いで、両側の注出口部シール部7を中心部に向けて両側から押圧することにより、注出口部10を筒状に容易に開口させることができる。この時、注出補助部材50d は、そのテープ基材51が長手方向に樋状に湾曲するので、筒状に開口した注出口部10の保形性も向上され、最後までスムーズに内容物を注出することができる。
(A), (b), (c), and (d) of FIG. 11 are enlarged cross-sectional views taken along line A-A of FIG. 10 (a), respectively, to the spout portion of the spout assisting member. It is a figure which shows the example of sticking.
FIG. 11 (a) shows an embossed portion S that bulges outward on one side of the wall film 1, 1 ′ on both sides of the spout 10 and has the configuration shown in FIG. It is a figure which shows the example which inserted and stuck the extraction | pouring auxiliary member 50d.
In this case, in the cross-sectional portion taken along the line A-A in the figure, the extraction assisting member 50d is not attached to the inner surface of the wall film 1 and is housed in the embossed portion S.
Thus, by sticking the pouring auxiliary member 50d to the pouring port portion 10 of the bag 300a with the pouring port portion (see (a) of FIG. 10), the wall films 1, 1 'on both sides of the pouring port portion 10 are adhered. Since the gap is surely formed by the dispensing auxiliary member 50d in between, the tip of the spout 10 is opened along the half-cut line 11 when the contents filled in the bag 300a are poured out. Thus, the spout 10 is automatically opened, and then the spout 10 is easily opened in a cylindrical shape by pressing the spout seals 7 on both sides toward the center from both sides. Can do. At this time, since the tape base 51 is bent in a longitudinal shape in the longitudinal direction, the pouring auxiliary member 50d is improved in the shape retaining property of the pouring port portion 10 opened in a cylindrical shape, and the contents can be smoothly transferred to the end. Can be dispensed.

図11の(ロ)は、注出口部10の両面の壁面フィルム1、1′にそれぞれ外側に膨らむエンボス部Sを設け、その内側に前記図4に示した構成の注出補助部材50d をその凸条同士が対向するように挿入して貼着した例を示す図である。
この場合も、図示したA−A線の断面部では、両側の注出補助部材50d は、壁面フィルム1、1′の内側の面に貼着されておらず、それぞれエンボス部Sの内部に収納された状態である。この点は以下の(ハ)、(ニ)に示す図においても同様である。
図11の(ロ)に示したように注出補助部材50d を袋300a の注出口部10に貼着することにより、注出口部10の両面の壁面フィルム1、1′に注出補助部材50d が貼着されているので、注出口部10の両面の壁面フィルム1、1′の間には、前記図11の(イ)の場合よりも更に大きな空隙部が形成され、注出口部10をハーフカット線11で開封することにより、自動的に一層大きく注出口部10が開口する。そして、両側の注出口部シール部7を両側から中心部に向けて押圧することにより、両側の注出補助部材50d が、それぞれ外側に樋状に湾曲するので、注出口部10を円筒状に容易に開口させることができ、また、円筒状に開口した注出口部10の保形性も一層優れたものになり、最後まで一層スムーズに内容物を注出できるようになる。
11 (b) is provided with embossed portions S that bulge outward on the wall surface films 1, 1 'on both sides of the spout portion 10, and the dispensing auxiliary member 50d having the structure shown in FIG. It is a figure which shows the example inserted and stuck so that convex stripes might oppose.
Also in this case, in the cross-sectional portion of the AA line shown in the figure, the extraction assisting members 50d on both sides are not attached to the inner surfaces of the wall surface films 1, 1 ', and are housed in the embossed portions S, respectively. It is the state that was done. The same applies to the following drawings (c) and (d).
As shown in FIG. 11 (b), the extraction assisting member 50d is attached to the outlet 10 of the bag 300a so as to adhere to the wall films 1, 1 'on both sides of the outlet 10. Is attached between the wall surface films 1, 1 ′ on both sides of the spout portion 10, so that a larger gap is formed than in the case of FIG. By opening with the half cut line 11, the spout part 10 automatically opens larger. Then, by pressing the spout portion seal portions 7 on both sides toward the center from both sides, the spout assisting members 50d on both sides are curved outwardly in a bowl shape, so that the spout portion 10 is made cylindrical. It can be easily opened, and the shape retaining property of the spout portion 10 opened in a cylindrical shape is further improved, so that the contents can be poured out more smoothly to the end.

図11の(ハ)は、注出口部10の両面の壁面フィルム1、1′のうち、片面の壁面フィルム1に外側に膨らむエンボス部Sを設け、その内側に前記図6に示した構成の注出補助部材50f を挿入して貼着した例を示す図である。
このように注出補助部材50f を注出口部10の片側の壁面フィルム1の内側の面に貼着した場合も、図11の(イ)の場合と同様に、注出口部10の両面の壁面フィルム1、1′の間には注出補助部材50f により確実に空隙部が形成されるので、注出口部10をハーフカット線11で開封することにより、自動的に注出口部10が開口する。そして、注出口部10の両側の注出口部シール部7を中心部に向けて両側から押圧することにより、注出口部10を筒状に容易に開口させることができる。この時、注出補助部材50f は、そのテープ基材51の幅方向の中央部にその流れ方向に沿って薄肉部による折り曲げ線54が設けられているのでV字状に外側に折り曲げられ、そのリブ効果により、筒状に開口した注出口部10の保形性も向上され、最後までスムーズに内容物を注出することができる。
(C) in FIG. 11 is provided with an embossed portion S that swells outward on one side wall film 1 out of the wall surface films 1 and 1 ′ on both sides of the spout portion 10, and has the configuration shown in FIG. It is a figure which shows the example which inserted and stuck the extraction | pouring auxiliary member 50f.
Thus, also when sticking out the auxiliary member 50f on the inner surface of the wall film 1 on one side of the spout portion 10, the wall surfaces on both sides of the spout portion 10 are the same as in the case of FIG. Since the void portion is surely formed between the films 1 and 1 'by the dispensing auxiliary member 50f, the dispensing portion 10 is automatically opened by opening the dispensing portion 10 with the half-cut line 11. . And the spout part 10 can be easily opened to a cylinder shape by pressing the spout part seal | sticker part 7 of the both sides of the spout part 10 toward a center part from both sides. At this time, the dispensing auxiliary member 50f is bent outward in a V shape because the folding line 54 is formed by a thin portion along the flow direction at the center of the tape base 51 in the width direction. Due to the rib effect, the shape retaining property of the spout portion 10 opened in a cylindrical shape is also improved, and the contents can be smoothly poured out to the end.

図11の(ニ)は、注出口部10の両面の壁面フィルム1、1′にそれぞれ外側に膨らむエンボス部Sを設け、その内側に前記図6に示した構成の注出補助部材50f をその凸条同士が対向するように挿入して貼着した例を示す図である。
このように注出補助部材50f を注出口部10の内側の面に貼着することにより、図11の(ロ)の場合と同様に、注出口部10の両面の壁面フィルム1、1′の間には両側の注出補助部材50f により大きな空隙部が形成されるので、注出口部10をハーフカット線11で開封することにより、自動的に注出口部10が大きく開口する。次いで、注出口部10の両側の注出口部シール部7を中心部に向けて両側から押圧することにより、両側の注出補助部材50f が、その薄肉部による折り曲げ線54でそれぞれV字状に外側に折り曲げられ、注出口部10が角筒状に容易に保形性よく開口され、袋に充填された内容物を最後までスムーズに注出することができる。
11 (d) is provided with embossed portions S that bulge outward on the wall surface films 1, 1 'on both sides of the spout portion 10, and the dispensing auxiliary member 50f having the structure shown in FIG. It is a figure which shows the example inserted and stuck so that convex stripes might oppose.
By sticking the pouring auxiliary member 50f to the inner surface of the spout portion 10 in this way, the wall films 1, 1 'on both sides of the spout portion 10 are similar to the case of FIG. Since a large gap is formed by the extraction assisting members 50f on both sides, the opening 10 is automatically opened largely by opening the outlet 10 with the half-cut line 11. Next, by pressing the spout portion seal portions 7 on both sides of the spout portion 10 toward the center from both sides, the spout assisting members 50f on both sides are respectively V-shaped at the folding lines 54 by the thin portions. The outlet 10 is easily opened in a square tube shape with good shape retention, and the contents filled in the bag can be smoothly poured out to the end.

Further, the ridges 52a and 52b provided at the edge portions on both sides were formed so that the height including the tape base 51 was 1.6 mm and the width was 1.5 mm.
In addition, this pouring auxiliary member is produced by a modified co-extrusion molding method.
(4) Size of Bag with Spout Portion The size of the bag was 130 mm in overall width, 190 mm in total length, and 38 mm in folding length of the bottom gusset portion 4.
The spout portion 10 has the shape shown in the drawing, and its opening position, that is, the full width of the position where the half cut line 11 is provided is 26 mm, and the length from the half cut line 11 to the line B indicating the base of the spout portion is about 20 mm, and the taper angle of the spout 10 was 38 °.
In addition, the sticking length to the spout part 10 of the said spout auxiliary member 50d is the position which further exceeds the opening position of the spout part 10, ie, the line B which shows the base part of a spout part from the half cut line 11. The total length was 35 mm.
Further, as shown in FIG. 11A, the sticking auxiliary member 50d is attached to the spout portion 10 as shown in FIG. Went to 1 only. However, it differs from (a) in FIG. 11 in that the embossed portion S is not provided.

前記実施例1の注出口部付き袋の構成において、注出補助部材50d の注出口部10への貼着のみを、図11の(ロ)に示すように注出口部10の両面の壁面フィルム1、1′にその凸条同士が対向するように貼着したほかは、総て実施例1と同様に作製して実施例2の注出口部付き袋とした。   In the configuration of the bag with the spout portion of Example 1, only the sticking of the spout auxiliary member 50d to the spout portion 10 is performed on the wall surface films on both sides of the spout portion 10 as shown in FIG. A bag with a spout part of Example 2 was produced in the same manner as Example 1 except that the protruding strips 1 and 1 'were stuck so as to face each other.

前記実施例1の注出口部付き袋の構成において、注出口部10に貼着した注出補助部材50d のみを、図6に示した構成の注出補助部材50f に変更して貼着した〔図11の(ハ)参照〕ほかは総て実施例1と同様に作製して実施例3の注出口部付き袋とした。   In the configuration of the bag with the spout portion of Example 1, only the spout auxiliary member 50d attached to the spout portion 10 was changed to the spout auxiliary member 50f having the configuration shown in FIG. The other parts were produced in the same manner as in Example 1 to obtain a bag with a spout part in Example 3.

前記実施例1の注出口部付き袋の構成において、注出口部10に貼着した注出補助部材50d を、図6に示した構成の注出補助部材50f に変更すると共に、図11の(ニ)に示すように注出口部10の両面の壁面フィルム1、1′にその凸条同士が対向するように貼着したほかは、総て実施例1と同様に作製して実施例4の注出口部付き袋とした。   In the configuration of the bag with the spout portion in Example 1, the spout assisting member 50d adhered to the spout portion 10 is changed to a spout assisting member 50f having the configuration shown in FIG. As shown in d), all of the films were prepared in the same manner as in Example 1 except that the protruding films 10 were adhered to the wall surface films 1, 1 ′ on both sides of the spout part 10 so that the ridges face each other. It was set as the bag with a spout part.

(試験およびその結果)
以上のように作製した実施例1、2、3、4の注出口部付き袋の注出適性を評価するため、それぞれの注出口部付き袋に、未シールの上部シール部8から内容物として液体シャンプーを約400ml充填した後、上部シール部8をヒートシールして袋を密封した。
上記のように作製した実施例1、2、3、4の注出口部付き袋による包装体は、いずれも安定した自立性を有し、外観もよく取り扱い性にも優れていた。
また、各包装体に充填された液体シャンプーの注出適性試験を行うため、先ず、各包装体の注出口部10の先端部を摘んでノッチ12a を始点としてハーフカット線11に沿って引き裂いたところ、いずれもハーフカット線11に沿ってきれいに引き裂いて注出口部10を開封することができた。この時、ハーフカット線11に沿って注出補助部材の切断端部が存在していたため、これが引き裂き方向のずれ防止にも寄与したものと考えられる。
(Test and results)
In order to evaluate the pouring aptitude of the bag with the spout part of Examples 1, 2, 3, and 4 produced as described above, the contents from the unsealed upper seal part 8 to each bag with the spout part After filling about 400 ml of liquid shampoo, the upper seal 8 was heat sealed to seal the bag.
The packaging bodies with bags with spout portions of Examples 1, 2, 3, and 4 produced as described above all had stable self-supporting properties, had good appearance, and were excellent in handleability.
In addition, in order to perform the dispensing suitability test of the liquid shampoo filled in each package, first, the tip of the spout 10 of each package is picked and torn along the half-cut line 11 starting from the notch 12a. However, it was possible to open the spout 10 by tearing cleanly along the half-cut line 11. At this time, since the cut end portion of the extraction assisting member was present along the half-cut line 11, it is considered that this also contributed to prevention of displacement in the tearing direction.

そして、注出口部10の開封と同時に、図11の(イ)、(ロ)、(ハ)、(ニ)で説明したように、いずれの包装体も自動的に注出口部10が開口し、更に、手で注出口部シール部7を両側から中心部に向けて軽く押圧するだけで、容易に注出口部10を筒状に開口させることができた。
特に、実施例2および実施例4の包装体は、注出口部10の両面の壁面フィルム1、1′に注出補助部材が貼着されているので、筒状に開口した開口部の保形性が優れており、安定した筒状の開口部を形成していた。
Simultaneously with the opening of the spout 10, the spout 10 is automatically opened in any package as described in (a), (b), (c) and (d) of FIG. 11. Furthermore, the spout part 10 could be easily opened in a cylindrical shape simply by lightly pressing the spout part seal part 7 from both sides toward the center.
In particular, the packaging bodies of Example 2 and Example 4 have the shape of the opening that is opened in a cylindrical shape because the pouring auxiliary members are adhered to the wall surface films 1, 1 ′ on both sides of the spout 10. The properties were excellent, and a stable cylindrical opening was formed.

次いで、開口させた注出口部10を別に用意したボトルの口部(口部の内径は26mm)に差し込んで、充填された液体シャンプーの注出を行ったところ、いずれの包装体も注出の途中で注出口部10が、その基部近辺で折れ曲がって閉塞するようなこともなく、最後までスムーズに液体シャンプーを注出することができ、注出適性に優れていた。   Next, the opened spout 10 was inserted into the mouth of a separately prepared bottle (the inner diameter of the mouth was 26 mm) and the filled liquid shampoo was poured out. The spout portion 10 did not bend and close in the vicinity of the base portion on the way, and the liquid shampoo could be smoothly poured out to the end, which was excellent in pourability.

本発明の注出補助部材を袋の注出口部に貼着した注出口部付き袋は、例えば、シャンプー、コンディショナー、ボディーソープ、家庭用液体洗剤、その他液体調味料、食用油、各種の飲料など、液状の内容物を密封包装し、内容物を使用する際に、ボトルなどの他の容器に移し替えて使用するような詰め替え用の包装袋に使用するのに特に適しているが、用途に関しては特に制限はない。
