However, in the case where the content easily penetrates into the sealant layer, it is preferable to laminate by the dry lamination method.

次に、本願発明の特徴である、注出口における注出補助部材について、その具体的構
成を説明する。図5は注出補助部材の正面図(a)および斜視図(b)、図6は注出補助部材が2層からなるときの平面断面図である。図2や図4に示すように、この注出口3aの内側であって、ハーフカット線11よりもやや下方から本体2内側方に向けて積層フィルム4,4´の内側面に、注出補助部材14が熱成形などして取付けられる。なお、上述したように、注出補助部材14上端部の位置が、ハーフカット線11の位置と重複しないように、注出補助部材14が注出口3aの内側に取付けられる。
Next, the specific configuration of the dispensing auxiliary member at the spout, which is a feature of the present invention, will be described. FIG. 5 is a front view (a) and a perspective view (b) of the extraction assisting member, and FIG. 6 is a plan sectional view when the extraction assisting member has two layers. As shown in FIG. 2 and FIG. 4, on the inner surface of the laminated film 4, 4 ′ inside the spout 3 a and slightly below the half-cut line 11 toward the inner side of the main body 2, The member 14 is attached by thermoforming or the like. As described above, the extraction assisting member 14 is attached to the inner side of the outlet 3a so that the position of the upper end portion of the extraction assisting member 14 does not overlap the position of the half-cut line 11.

この注出補助部材14は、図5〜6に示すように、長手方向に開放部14a(隙間)を有する、全体が樋状(断面視略C字)の弾性部材からなるものである。また、注出補助部材14は開放部14aと対向する部分から積層フィルム4に取り付けられるが、そのとき、積層フィルム4には注出補助部材14の開放部14aに向かって、引っ張られる力が働く。注出補助部材14が開放部14aを有し、且つ弾性体であることにより、注出補助部材14が弾性変形して取り付ける前の状態の外径より小さくなり、積層フィルム4に掛かる引張力や外力を軽減させることができるため、積層フィルム4の損傷や皺の発生を防止することができる。積層フィルム4´についても同様である。注出補助部材14が筒状体のような開放部14aを有しない形状では、弾性変形しても外径を小さくさせることができず(外周の周長を短くすることができず)、積層フィルム4,4´に掛かる引張力や外力を軽減させることができない。また、注出補助部材14は取り付けられる前の状態より外径が小さくなるように取り付けられるため、常に外向きの力が働き、注出口における内容物の注出経路の開口性と保形性を経時的に安定維持でき、内容物の注出性を向上することができる。なお、注出補助部材14の開放部14aを含む中央の空洞部が内容物を注出する流体の流通経路(図4の斜線部)となる。なお、注出補助部材14の開放部14aを含む中央の空洞部が内容物を注出する流体の流通経路(図4の斜線部)となる。そして、この注出補助部材14は、その製造工程において、長尺の巻取状に作製されたものを、後述する図14に示すようなローラーR間におけるこれらローラーRに沿って牽引搬送し、このローラーR上で必要な長さに切断されて、注出口付包装袋1に取付けられる。   As shown in FIGS. 5 to 6, the dispensing auxiliary member 14 is made of an elastic member having an open portion 14 a (gap) in the longitudinal direction and having a generally bowl shape (substantially C-shaped in cross section). In addition, the extraction assisting member 14 is attached to the laminated film 4 from a portion facing the opening portion 14a. At that time, a pulling force acts on the laminated film 4 toward the opening portion 14a of the dispensing auxiliary member 14. . Since the extraction auxiliary member 14 has an open portion 14a and is an elastic body, the extraction auxiliary member 14 is elastically deformed to be smaller than the outer diameter in the state before being attached, and the tensile force applied to the laminated film 4 can be reduced. Since external force can be reduced, damage to the laminated film 4 and generation of wrinkles can be prevented. The same applies to the laminated film 4 ′. If the dispensing auxiliary member 14 has a shape that does not have an open portion 14a such as a cylindrical body, the outer diameter cannot be reduced even if elastically deformed (the circumference of the outer periphery cannot be shortened). The tensile force and external force applied to the films 4 and 4 'cannot be reduced. Moreover, since the pouring auxiliary member 14 is attached so that the outer diameter is smaller than the state before being attached, an outward force always acts, and the opening property and the shape retaining property of the pouring route of the contents at the pouring port are improved. It can be stably maintained over time, and the contents can be poured out. The central cavity including the open portion 14a of the extraction auxiliary member 14 serves as a fluid flow path (shaded portion in FIG. 4) for extracting the contents. The central cavity including the open portion 14a of the extraction auxiliary member 14 serves as a fluid flow path (shaded portion in FIG. 4) for extracting the contents. And in this manufacturing process, this extraction auxiliary member 14 pulls and conveys what was produced in a long winding shape along these rollers R as shown in FIG. It is cut into a required length on the roller R and attached to the packaging bag 1 with a spout.

図10は他の形状の注出補助部材を例示した平面図である。この図10に示すように、注出補助部材14´,14´´,14´´´の開放部14aに対向する部分の長手方向に薄肉部14bを設けた場合は、薄肉部14bを中心として両側の厚肉部14dが左右に弾性変形しやすくなり、より一層積層フィルム4,4´に掛かる引張力や外力を軽減させることができる。図10(a)及び(b)は略円形の一部分が欠けた形状、図10(c)は略楕円形の一部分が欠けた形状となっている。これら図10(a)〜(c)は、積層フィルム4,4´に取付けることで、弾性変形によって、欠けた面積が全体の面積の半分未満となり、注出口における内容物の注出経路の開口性と保形性および内容物の排出性をより一層向上させることができる。なお、図10(a)の注出補助部材14´では、積層フィルム4,4´に取付けた状態で弾性変形により、欠けた面積が全体の面積の半分未満となるため、注出口3a(流通経路)の開口面積を広くすることができ、例えば高粘度を有する内容物などの注出性に優れる。また、図10(c)のように注出補助部材14´´´を略楕円形とした場合は、注出口付包装袋1を整列させた際に並べ易くなる。また、薄肉部14bは外面を凹状あるいは略平坦にしてもよい。薄肉部14bの外面を平坦にした場合は、注出補助部材14〜14´´´を積層フィルム4の内側面により確実に取り付けることができる。   FIG. 10 is a plan view illustrating another shape of the extraction assisting member. As shown in FIG. 10, when the thin portion 14b is provided in the longitudinal direction of the portion facing the opening portion 14a of the extraction assisting members 14 ′, 14 ″, 14 ″ ″, the thin portion 14b is the center. The thick wall portions 14d on both sides are easily elastically deformed left and right, and the tensile force and external force applied to the laminated films 4 and 4 'can be further reduced. FIGS. 10A and 10B show a shape in which a part of a substantially circular shape is missing, and FIG. 10C shows a shape in which a part of a substantially elliptical shape is missing. 10 (a) to 10 (c) are attached to the laminated films 4 and 4 ', the chipped area becomes less than half of the entire area due to elastic deformation, and the opening of the content extraction path at the spout Performance, shape retention, and discharge of contents can be further improved. In addition, in the extraction | pouring auxiliary member 14 'of Fig.10 (a), since the chipped area becomes less than half of the whole area by elastic deformation in the state attached to the laminated films 4 and 4', the spout 3a (circulation) The opening area of the route) can be widened, and, for example, the content having a high viscosity is excellent in the pouring property. Moreover, when the extraction | pouring auxiliary | assistance member 14 '' '' is made into a substantially elliptical shape like FIG.10 (c), it will become easy to arrange when the packaging bag 1 with an outlet is aligned. The thin portion 14b may have a concave or substantially flat outer surface. When the outer surface of the thin portion 14 b is flattened, the extraction assisting members 14 to 14 ″ ″ can be reliably attached to the inner surface of the laminated film 4.

なお、この注出補助部材14〜14´´´のサイズ例として、例えば、注出口付包装袋1の注出口3aを構成する積層フィルム4,4´の幅(ヒートシール部を含む)が約11mmである場合には、注出補助部材14〜14´´´の断面における幅aを4mm程度、厚肉部14dの厚みbを0.6mm〜0.7mm程度、薄肉部14bの厚みcを0.3mm〜0.4mmとする。これは詰め替え容器の口部の内径が11mmのものに対応しており、注出口部3aの幅は注出補助部材の幅a(4mm)+注出口シール部9の幅(3mm)+注出口シール部9の幅(3mm)+ノッチの幅(1mm)で決定される。従って、注出口シール部9の幅が3mm、ノッチの幅を1mmとすると、詰め替え容器の口部の内径が15mmの場合は、注出補助部材14の幅aを8mm程度、詰め替え容器の口部の内径が23mmの場合は、注出補助部材14の幅aを16mm程度とすることができる。本願の注出補助部材14は、注出口3aの幅が11〜23mmのような小口径の注出口付包装袋1に最適である。小口径の注出口付包装袋1において、注出補助部材14が筒状体のような開放部14aを有しない形状では曲率半径が小さくなり、積層フィルム4,4´に引張力や外力が掛かりやすくなるため、積層フィルム4,4´が破損しやすく、また、注出補助部材14がフィルムの少なくとも一方の端部に凸条が設けられた形状では注出口シール部をヒートシールしたときに凸条が溶融してしまうため、注出口3aの開口性と保形性が得られなくなる。   In addition, as an example of the size of the pouring auxiliary members 14 to 14 ″, for example, the width (including the heat seal portion) of the laminated films 4 and 4 ′ constituting the pouring port 3a of the packaging bag 1 with the pouring port is about. In the case of 11 mm, the width a in the cross section of the extraction assisting members 14 to 14 ″ ″ is about 4 mm, the thickness b of the thick portion 14 d is about 0.6 to 0.7 mm, and the thickness c of the thin portion 14 b is 0.3 mm to 0.4 mm. This corresponds to the mouth of the refill container having an inner diameter of 11 mm, and the width of the spout portion 3a is the width of the spout auxiliary member a (4 mm) + the width of the spout seal portion 9 (3 mm) + the spout. It is determined by the width of the seal portion 9 (3 mm) + the width of the notch (1 mm). Therefore, when the width of the spout seal 9 is 3 mm and the width of the notch is 1 mm, the width a of the dispensing auxiliary member 14 is about 8 mm and the mouth of the refill container when the inner diameter of the mouth of the refill container is 15 mm. When the inner diameter is 23 mm, the width a of the extraction assisting member 14 can be about 16 mm. The extraction assisting member 14 of the present application is optimal for the packaging bag 1 with an outlet having a small diameter such that the width of the outlet 3a is 11 to 23 mm. In the small-diameter packaging bag 1 with a spout, when the spout auxiliary member 14 does not have an open portion 14a such as a cylindrical body, the radius of curvature is small, and a tensile force or an external force is applied to the laminated films 4 and 4 '. The laminated films 4 and 4 ′ are easily damaged, and the pour-out assisting member 14 is convex when the pour-out seal portion is heat-sealed in a shape in which a ridge is provided on at least one end of the film. Since the strip melts, the opening and shape retention of the spout 3a cannot be obtained.

この注出補助部材14〜14´´´は、弾性を有するが、ここでいう弾性とは、積層フィルム4,4´の剛性よりも低い弾性のことを指す。注出補助部材14の弾性が積層フィルム4,4´の剛性より高いと、積層フィルム4,4´が損傷し、場合によっては裂けてしまう。注出補助部材14の弾性は材質や厚みで決まり、積層フィルム4,4´の剛性より低くなるよう適宜設計することができる。また、注出補助部材14の取り付け方法については特に限定されないが、生産性や高温高湿度下でも接着性が安定していることから、ヒートシールにて取り付けることが好ましい。その場合、注出補助部材14は、積層フィルム4,4´のシーラント層とヒートシールできる材質とし、例えば、中密度ポリエチレン、低密度ポリエチレン、ポリプロピレンなどから構成することができる。成形性の点から、注出補助部材14の材質は積層フィルム4,4´のシーラント層と同じ材質とすることが好ましい。   Although this extraction | pouring auxiliary member 14-14 '' '' has elasticity, the elasticity here refers to the elasticity lower than the rigidity of lamination films 4 and 4 '. If the elasticity of the dispensing auxiliary member 14 is higher than the rigidity of the laminated films 4 and 4 ′, the laminated films 4 and 4 ′ are damaged and may be torn in some cases. The elasticity of the dispensing auxiliary member 14 is determined by the material and thickness, and can be appropriately designed to be lower than the rigidity of the laminated films 4 and 4 ′. Moreover, although the attachment method of the extraction | pouring auxiliary member 14 is not specifically limited, Since adhesiveness is stable under productivity and high temperature and high humidity, it is preferable to attach by heat seal. In that case, the pouring auxiliary member 14 is made of a material that can be heat-sealed with the sealant layer of the laminated films 4 and 4 ′, and can be made of, for example, medium density polyethylene, low density polyethylene, polypropylene, or the like. From the viewpoint of moldability, it is preferable that the material of the extraction assisting member 14 is the same material as the sealant layer of the laminated films 4 and 4 ′.

また、図10(b)の形状を有する注出補助部材14において、その断面における幅aを4mm程度、厚肉部14dの厚みbを0.6mm〜0.7mm程度、薄肉部14bの厚みcを0.3mm〜0.4mm程度、開放部14aの間隔を1.0mm程度、開放部14aの幅を1.0mm程度、材質を密度0.915の低密度ポリエチレンとし、薄肉部14bを上面にして10cm×10cmの板を被せ、注出補助部材14が変形し始める圧縮力を測定したところ、圧縮力は15kgf(0.15kgf/cm2)であった。 Further, in the extraction assisting member 14 having the shape of FIG. 10B, the width a in the cross section is about 4 mm, the thickness b of the thick portion 14d is about 0.6 mm to 0.7 mm, and the thickness c of the thin portion 14b. Is about 0.3 mm to 0.4 mm, the interval between the open portions 14a is about 1.0 mm, the width of the open portions 14a is about 1.0 mm, the material is low density polyethylene with a density of 0.915, and the thin portion 14b is on the top surface. When the compressive force was measured by covering the 10 cm × 10 cm plate and the dispensing auxiliary member 14 started to deform, the compressive force was 15 kgf (0.15 kgf / cm 2 ).

また、注出補助部材14(14´〜14´´´でもよい)は、図6に示すような、少なくとも内側層部14iおよび外側層部14oからなる二層構造で構成してもよい。この場合、外側層部14oを構成する材質を、例えば密度0.915前後、融点100度前後の低密度ポリエチレンとし、内側層部14iを構成する材質を、例えば密度0.930前後、融点130度前後の高密度ポリエチレンとする。   Further, the extraction assisting member 14 (may be 14 ′ to 14 ″ ′) may have a two-layer structure including at least an inner layer portion 14i and an outer layer portion 14o as shown in FIG. In this case, the material constituting the outer layer portion 14o is, for example, low density polyethylene having a density of about 0.915 and a melting point of about 100 degrees, and the material constituting the inner layer portion 14i is, for example, a density of about 0.930 and a melting point of 130 degrees. The front and back high density polyethylene.

このような構成にすることで、内側層部14iの材質は外側層部14oの材質より融点が高いので、注出補助部材14を積層フィルム4,4´の内側面にヒートシールしたときに、内側層部14iは溶融しにくいため、注出口3aが閉塞しにくくなり、注出口3aの開口性および保形性を向上させることができる。また、上述の図10(a)〜(c)に示したような注出補助部材14´〜14´´´では、薄肉部14bの位置する外周部分を平らな形状(後述するローラRの接触面に水平となる水平面を有する)としているため、注出補助部材14´〜14´´´を積層フィルム4の内側面に仮付けする際には、図示しない平坦な上下シールバーを使用し、該下シールバーを積層フィルム4の下面に位置させ、開放部14aから前記上シールバーを注出補助部材14´〜14´´´の開放部14aと対向する部分に押し当てて、この開放部14aと対向する部分の外周部分を積層フィルム4の内側面に安定的に仮付けすることができる。なお、この仮付けする長さは、注出補助部材14´〜14´´´の全長の2/3以下の長さとされる。   By adopting such a configuration, the material of the inner layer portion 14i has a higher melting point than the material of the outer layer portion 14o, so when the heat extraction seal member 14 is heat sealed to the inner surface of the laminated films 4, 4 ′, Since the inner layer portion 14i is difficult to melt, the spout 3a is less likely to be blocked, and the openability and shape retention of the spout 3a can be improved. Further, in the extraction assisting members 14 ′ to 14 ″ ″ as shown in FIGS. 10A to 10C described above, the outer peripheral portion where the thin portion 14b is located has a flat shape (contact with a roller R described later). Since it has a horizontal surface that is horizontal to the surface), when temporarily attaching the extraction assisting members 14 ′ to 14 ″ ″ to the inner surface of the laminated film 4, use flat upper and lower seal bars (not shown), The lower seal bar is positioned on the lower surface of the laminated film 4, and the upper seal bar is pressed from the opening portion 14 a against the portion facing the opening portion 14 a of the extraction assisting members 14 ′ to 14 ″ ″. The outer peripheral part of the part facing 14a can be stably attached to the inner surface of the laminated film 4. Note that the length to be temporarily attached is not more than 2/3 of the total length of the extraction assisting members 14 ′ to 14 ″ ″.

ここで、注出補助部材14を積層フィルム4,4´の内側面にヒートシールして取付け
る方法について説明する。図7は包装袋一側の内側面に注出補助部材を取付ける成形工程の平面模式図、図8は包装袋他側の内側面に注出補助部材を取付ける成形工程の平面模式図(a)および成形を終えた完成図(b)、図9はシール型のシール位置により積層フィルムの緊張に伴う注出補助部材の撓みを示す注出補助部材の平面図(a)および弾性により注出補助部材が元の形状に戻った注出補助部材の平面図(b)、図10はシール型のシール位置により積層フィルムの緩みに伴う注出補助部材の収縮を示す注出補助部材の平面図(a)および弾性により注出補助部材が元の形状に戻った注出補助部材の平面図(b)である。
Here, the pouring auxiliary member 14 is heat-sealed and attached to the inner surface of the laminated films 4 and 4 '.
The method to be described is explained. FIG. 7 is a schematic plan view of the molding process for attaching the extraction assisting member to the inner side of the packaging bag. FIG. 8 is a schematic plan view of the molding process for attaching the extraction auxiliary member to the inner side of the other side of the packaging bag. FIG. 9 is a completed drawing (b), and FIG. 9 is a plan view of the pouring auxiliary member showing the deflection of the pouring auxiliary member due to the tension of the laminated film depending on the sealing position of the seal mold, and the pouring assist by elasticity FIG. 10 is a plan view of the dispensing auxiliary member in which the member has returned to its original shape, and FIG. It is a top view (b) of the extraction assistance member which the extraction assistance member returned to the original shape by a) and elasticity.

まず、図7に示すように、注出口3aを構成する表側(または裏側)の積層フィルム4の内側面に、開放部14aから注出補助部材14の内側部に向けて凸型の成形金型15aを挿入した注出補助部材14の開放部14aと対向位置(図10の注出補助部材であれば薄肉部14b)を、成形金型15aにより押圧するとともに、開放部14aと対向位置(図10の注出補助部材であれば薄肉部14b)が位置する積層フィルム4の外側面は、凹型の成形金型15bの凹部に成形金型15aの押圧により嵌合させ、積層フィルム4の内側面と、注出補助部材14の周面とを熱プレス成形により溶着させる。   First, as shown in FIG. 7, a convex mold is formed on the inner side surface of the laminated film 4 on the front side (or back side) constituting the spout 3a from the open portion 14a toward the inner side of the pouring auxiliary member 14. The opening portion 14a of the pouring auxiliary member 14 into which 15a has been inserted is opposed to the open portion 14a (thin wall portion 14b in the case of the pouring auxiliary member of FIG. 10) by the molding die 15a, and the opening portion 14a is opposed to the open portion 14a (see FIG. The outer surface of the laminated film 4 on which the thin portion 14b) is positioned is fitted into the concave portion of the concave molding die 15b by pressing the molding die 15a. And the peripheral surface of the pouring auxiliary member 14 are welded by hot press molding.

このとき、上述したように、注出補助部材14に、外面が平坦な薄肉部14bを有していれば、その外面の平坦部が、積層フィルム4,4´の内側面に熱成形で平面的に固定されるため、注出補助部材14を積層フィルム4,4´の内側面に確実に溶着固定させることができる。なお、成形金型15a,15bは周知技術であるため、それら詳細な説明は省略する。   At this time, as described above, if the dispensing auxiliary member 14 has the thin portion 14b whose outer surface is flat, the flat portion of the outer surface is flat on the inner surface of the laminated films 4 and 4 'by thermoforming. Therefore, the dispensing auxiliary member 14 can be reliably welded and fixed to the inner surface of the laminated films 4 and 4 ′. Since the molding dies 15a and 15b are well-known techniques, their detailed description is omitted.

次いで、図8(a)に示すように、注出口3aを構成する裏側(または表側)の積層フィルム4´の内側面に、注出補助部材14の開放部14a側を接触させるとともに、これら開放部14a側が位置する積層フィルム4´の外側面を、凹型の成形金型15cの凹部に嵌合させ、積層フィルム4´の内側面と、注出補助部材14の開放部14a側における所定の長さの周面とを熱プレス成形により溶着させる。そして、図8(b)に示すように、注出補助部材14は取り付けられる前の状態より外径が小さくなるため、開放部14aの間隔も取り付けられる前の状態より狭くなっている。開放部14aは取り付けられたときに閉じてもよいが、取り付けられた状態でも開放部14aがある場合は、注出口3aの開口面積を広くすることができ、注出量を増やすことができるため、例えば、内容物を高粘度のものとしたときに有効である。   Next, as shown in FIG. 8A, the opening portion 14a side of the pouring auxiliary member 14 is brought into contact with the inner side surface of the laminated film 4 'on the back side (or the front side) constituting the spout 3a, and these openings are opened. The outer surface of the laminated film 4 ′ on which the portion 14 a side is located is fitted into the recess of the concave molding die 15 c, and a predetermined length on the inner surface of the laminated film 4 ′ and the opening portion 14 a side of the dispensing auxiliary member 14 The peripheral surface is welded by hot press molding. And as shown in FIG.8 (b), since the outer diameter of the extraction assistance member 14 becomes smaller than the state before being attached, the space | interval of the open part 14a is also narrower than the state before being attached. The open portion 14a may be closed when attached, but if the open portion 14a is present even in the attached state, the opening area of the spout 3a can be increased and the amount of pouring can be increased. For example, it is effective when the contents are made of high viscosity.

このように、積層フィルム4,4´の内側面に注出補助部材14を成形シール後、冷却するとともに、上述したように注出口部3を注出口シール部9でヒートシールして注出口付包装袋1が成形される。   As described above, the casting auxiliary member 14 is molded and sealed on the inner side surfaces of the laminated films 4 and 4 ′ and then cooled, and as described above, the outlet 3 is heat-sealed with the outlet sealing portion 9 and the outlet is attached. A packaging bag 1 is formed.

ここで、例えば、図9に示すように、内側面に注出補助部材14を固定させた積層フィルム4,4´の成形金型15b,15cによるヒートシール位置がずれた場合などには、シール位置のずれに伴い積層フィルム4,4´の引っ張りに追従して、注出補助部材14が、薄肉部14bを中心として両側の厚肉部が左右に弾性変形することで、積層フィルム4,4´が応動する。従って、積層フィルム4,4´に無理な張力がかからず、積層フィルム4,4´の破断を防ぐことができる。   Here, for example, as shown in FIG. 9, when the heat sealing position by the molding dies 15b and 15c of the laminated films 4 and 4 ′ having the pouring auxiliary member 14 fixed to the inner surface is shifted, the sealing is performed. Following the pulling of the laminated films 4 and 4 ′ with the displacement, the pouring auxiliary member 14 elastically deforms the thick parts on both sides centering on the thin part 14 b to the left and right, so that the laminated films 4 and 4. 'Responds. Therefore, excessive tension is not applied to the laminated films 4 and 4 ′, and breakage of the laminated films 4 and 4 ′ can be prevented.

また、上記とは異なる形状の成形金型15b´,15c´(図示しない)によりヒートシールすることもできるため、一つの注出補助部材14で様々な形状に対応することができる。   In addition, since heat sealing can be performed with molding dies 15b 'and 15c' (not shown) having shapes different from the above, various shapes can be accommodated by the single dispensing auxiliary member 14.

なお、注出補助部材14の形状は、上述した形状に限定されない。   In addition, the shape of the extraction | pouring auxiliary member 14 is not limited to the shape mentioned above.

さらに、注出口3aへの注出補助部材14の取付方向も上述に限定しない。図11は
補助部材の他の取付例を示す注出口付近の拡大側面図である。
Furthermore, the mounting direction of the pouring auxiliary member 14 to the pouring port 3a is not limited to the above. FIG. 11 is an enlarged side view of the vicinity of the spout showing another example of attachment of the auxiliary member.

この場合、注出補助部材14は、図11に示すように、開放部14aを、注出口3aを構成する積層フィルム4,4´のヒートシールされた溶着部の方向(図例では、右方向だが、左方向でもよい)を向くようにして、上述同様に積層フィルム4,4´の内側面に注出補助部材14を熱プレス成形により溶着させてもよい。   In this case, as shown in FIG. 11, the pouring assisting member 14 opens the opening portion 14a in the direction of the heat-sealed welded portion of the laminated films 4 and 4 ′ constituting the pouring port 3a (in the example, the right direction). However, the pouring auxiliary member 14 may be welded to the inner side surfaces of the laminated films 4 and 4 ′ by hot press molding in the same manner as described above.

このような構成にすることで、注出補助部材14の中央空洞部が、開放部14aを介して注出補助部材14外方である、積層フィルム4,4´のヒートシールされた溶着部までの隙間と連通するため、内容物の流通面積を大きくでき、注出性をいっそう向上させることができる。   By adopting such a configuration, the central hollow portion of the pouring auxiliary member 14 is outside the pouring auxiliary member 14 through the open portion 14a, up to the heat-sealed welded portion of the laminated films 4 and 4 ′. Therefore, the distribution area of the contents can be increased, and the pouring property can be further improved.

以上詳述したように、この例の注出口付包装袋1は、積層フィルム4,4´からなる包装袋の一端部に、開封手段(ハーフカット線11およびノッチ12)を備える注出口部3を設け、この注出口部3を開封して形成した注出口3aの内側には、積層フィルム4,4´の内側面に取付けた注出補助部材14を備え、注出口3aから注出補助部材14を介して包装袋の内容物を注出させるとともに、この注出補助部材14は、長手方向に開放部14aを有する樋状の弾性部材からなるものである。   As described above in detail, the packaging bag with spout 1 of this example has a spout portion 3 provided with an opening means (half-cut line 11 and notch 12) at one end of the packaging bag made of the laminated films 4 and 4 '. The inside of the spout 3a formed by opening the spout 3 is provided with a spout auxiliary member 14 attached to the inner surface of the laminated films 4 and 4 '. The contents of the packaging bag are poured out via 14, and the dispensing auxiliary member 14 is made of a bowl-shaped elastic member having an open portion 14 a in the longitudinal direction.

次に、上述したように注出補助部材14は、その製造工程において、長尺の巻取状に作製されたものを、後述する図14に示すようなローラーR間であって、このローラーRに沿って牽引搬送され、ローラーR上で必要な長さに切断される。   Next, as described above, in the manufacturing process, the extraction assisting member 14 is formed in a long winding shape between rollers R as shown in FIG. And is cut to a required length on the roller R.

以下の記載では、この注出口付包装袋1の製造を、より迅速かつ容易にしたものである。   In the following description, the manufacture of the packaging bag 1 with a spout is made quicker and easier.

図12は板状部材からなる幅の狭い突部を備える注出補助部材の断面側面図(a)、幅広の突部を備える注出補助部材の断面側面図(b)および一方向に設けた突部を備える注出補助部材の断面側面図(c)、図13は積層フィルムにヒートシールさせた、注出口シール部に達しない幅の狭い突部を備える注出補助部材の断面側面図(a)および注出口シール部に達する幅広の突部を備える注出補助部材の断面側面図(b)である。   FIG. 12 is a cross-sectional side view (a) of a pouring auxiliary member having a narrow protrusion made of a plate-like member, a cross-sectional side view (b) of a pouring auxiliary member having a wide protrusion, and provided in one direction. FIG. 13 is a cross-sectional side view of a dispensing auxiliary member having a protrusion, and FIG. 13 is a cross-sectional side view of a dispensing auxiliary member having a narrow protrusion that does not reach the spout sealing portion, heat-sealed to the laminated film. It is a cross-sectional side view (b) of the extraction assistance member provided with the wide protrusion which reaches a) and a spout seal part.

この注出補助部材は、例えば、上述した図10(b)に示す形状のものを例に用い、その外周縁部に、外側方に向けて突出させた突部を設けたものである。   For example, the above-described extraction assisting member has the shape shown in FIG. 10B described above, and is provided with a protruding portion that protrudes outwardly on the outer peripheral edge thereof.

この場合、例えば図12(a)に示すように、注出補助部材16として、開放部14aに対向する部分(薄肉部14b)から注出補助部材16の外周縁部oにおける、図示する接線Lに沿い左右両側方に向けて略均等に、板状部材からなる突出幅fおよび厚みeを有する突部w1が、注出補助部材16の長さ方向(搬送方向)に亘って取付けられる。そして、この突部w1は、左右各突出幅fを1.0mm程度、厚みeを0.2〜0.3mm程度とすることができる。さらに、この場合の注出補助部材16の幅aを4.0mm程度、厚肉部14dの厚みbを0.6mm〜0.7mm程度、薄肉部14bの厚みcを0.3mm〜0.4mmとすることができる。なお、注出補助部材16本体の幅gは4.6mm程度、左右の突出幅fと開放部14aに対向する部分(薄肉部14bの長さ)を足した長さdを5.0mm程度とすることができる。このように突部w1を注出補助部材16本体に対して左右均等に突設させているため、注出補助部材16を、後述する図14に示すローラーR上で安定的に搬送させることができる。   In this case, for example, as shown in FIG. 12 (a), the tangent L shown in the figure from the portion (thin portion 14b) facing the opening 14a to the outer peripheral edge o of the extraction auxiliary member 16 as the extraction auxiliary member 16. A protrusion w1 made of a plate-like member having a protrusion width f and a thickness e is attached over the length direction (conveyance direction) of the dispensing auxiliary member 16 substantially uniformly toward the left and right sides. And this protrusion w1 can make each right-and-left protrusion width f about 1.0 mm, and thickness e about 0.2-0.3 mm. Further, in this case, the width a of the extraction assisting member 16 is about 4.0 mm, the thickness b of the thick portion 14d is about 0.6 mm to 0.7 mm, and the thickness c of the thin portion 14b is 0.3 mm to 0.4 mm. It can be. It should be noted that the width g of the pouring auxiliary member 16 main body is about 4.6 mm, and the length d obtained by adding the left and right protruding widths f and the portion facing the open portion 14a (the length of the thin portion 14b) is about 5.0 mm. can do. Thus, since the protrusion w1 is provided so as to protrude evenly with respect to the main body of the extraction auxiliary member 16, the extraction auxiliary member 16 can be stably conveyed on a roller R shown in FIG. it can.

この突部w1(後述するw2〜w7を含む)は、上述した注出補助部材16(後述する16´〜16´´を含む)の材質と同じ材質を用いてもよく、また、これら突部を、注出補助部材と一体成形させたり、あるいは別個に成形したものを後の工程で互いに溶着させるなど、その製造方法は限定しない。   The protrusions w1 (including w2 to w7 described later) may be made of the same material as the above-described extraction assisting member 16 (including 16 ′ to 16 ″ described later), and these protrusions The manufacturing method thereof is not limited, for example, integrally molding with the dispensing auxiliary member, or separately molding them together in a later step.

また、図12(b)に示すように、上述した突部w1よりも左右の各突出幅fを長くした、厚みeを有するw2を設けた注出補助部材16´とすることもできる。   Moreover, as shown in FIG.12 (b), it can also be set as the extraction assistance member 16 'provided with w2 which has the thickness e which extended each protrusion width f on either side rather than the protrusion part w1 mentioned above.

なお、これら突部w1,w2の左右の各突出幅fは、図12(b)に示す広い場合で、両端部が注出口シール部9に到達するまで(注出口シール部9を超えて、外方にはみ出さない長さまで)の幅を有するものであり、図12(a)に示す狭い場合には、図14に示すようなローラーR上で注出補助部材を同じ向き(姿勢)で保てるように安定的に支持可能とする幅(短かすぎると注出補助部材を安定支持できない)であればよい。また、注出補助部材16´では、突部w2の左右各突出幅fが、注出補助部材16の突部w1の左右各突出幅fより長いため、ローラーRとの接触面積を大きくできることから、注出補助部材16に比べてさらに安定性を有するものである。   The left and right protrusion widths f of the protrusions w1 and w2 are wide in the case shown in FIG. 12 (b) until both ends reach the spout seal 9 (over the spout seal 9) In the case of the narrowness shown in FIG. 12 (a), the dispensing auxiliary member is placed in the same direction (posture) on the roller R as shown in FIG. It is sufficient that the width can be stably supported so that it can be maintained (if it is too short, the dispensing auxiliary member cannot be stably supported). Moreover, in the extraction | pouring auxiliary member 16 ', since each right-and-left protrusion width f of the protrusion w2 is longer than each right-and-left protrusion width f of the protrusion w1 of the extraction auxiliary member 16, it can enlarge a contact area with the roller R. Further, it is more stable than the extraction assisting member 16.

また、厚みeが薄すぎると、注出補助部材を安定支持させることができず、厚みeが厚すぎると、注出口3aを構成する積層フィルム4,4´の内側面にヒートシールする際、ヒートシール性を阻害してしまうほか、注出補助部材の厚肉部14dよりも厚い場合には、注出補助部材の弾性変形を妨げてしまうおそれがあるため、これらのことを勘案し、厚みeを30μm〜注出補助部材の厚肉部14dの厚みb未満とすることが好ましい。   Further, if the thickness e is too thin, it is not possible to stably support the dispensing auxiliary member, and if the thickness e is too thick, when heat-sealing to the inner surface of the laminated films 4 and 4 ′ constituting the spout 3 a, In addition to hindering heat sealability, there is a possibility that elastic deformation of the extraction assisting member may be hindered when the thickness is thicker than the thick portion 14d of the extraction assisting member. It is preferable that e is less than 30 μm to a thickness b of the thick portion 14d of the extraction assisting member.

また、図12(c)に示す注出補助部材16´´のように、開放部14aに対向する部分(薄肉部14b)から注出補助部材16の外周縁部oにおける、図示する接線Lに沿い左右のいずれか一側方に向けて板状部材からなる左右各突出幅fおよび厚みeを有する突部w3を、注出補助部材16の長さ方向に亘って取付けたものにしてもよい。なお、この場合も、突部w3の突出幅fは、先端が注出口シール部9に到達する位置から、注出補助部材16´´をローラーR上に安定支持可能とするまでの幅を有するものとされる。   Further, as shown in FIG. 12 (c), from the portion (thin wall portion 14b) facing the opening 14a to the tangent L shown in the figure at the outer peripheral edge o of the dispensing auxiliary member 16 A protrusion w3 having left and right protrusion widths f and thickness e made of a plate-shaped member toward one of the left and right sides along the side may be attached over the length direction of the dispensing auxiliary member 16. . In this case as well, the protrusion width f of the protrusion w3 has a width from the position where the tip reaches the spout seal 9 to the time when the discharge auxiliary member 16 ″ can be stably supported on the roller R. It is supposed to be.

そして、このような突部w1,w2,w3を備える注出補助部材16,16´,16´´にすることで、注出口付包装袋1の製造工程において、長尺の巻取状に作製しておいた注出補助部材16,16´,16´を、ローラーR上で必要な長さに切断する際、突部w1,w2,w3を、ローラーR面に接触させることで、ローラーR上で任意の外周方向(搬送方向に対して左右側方)に転位せず、注出補助部材16,16´,16´´がローラーR上で安定な姿勢を保ち、開放部16aを一定方向に揃えて注出補助部材16,16´,16´´を搬送することができる。   And by making into the extraction auxiliary | assistance member 16,16 ', 16' 'provided with such protrusions w1, w2, w3, in the manufacturing process of the packaging bag 1 with an outlet, it is produced in a long winding shape. When cutting out the extraction assisting members 16, 16 ′, 16 ′ that have been made to the required length on the roller R, the protrusions w <b> 1, w <b> 2, w <b> 3 are brought into contact with the roller R surface, so that the roller R It does not shift in any outer peripheral direction (left and right side with respect to the conveying direction) above, and the dispensing auxiliary members 16, 16 ′, 16 ″ maintain a stable posture on the roller R, and the opening 16a is in a certain direction. The extraction assisting members 16, 16 ′, 16 ″ can be conveyed in a uniform manner.

特に、突部w1,w2,w3は、開放部14aに対向する部分に設けた板状部材であるので、突部w1,w2,w3のローラーR面への接触面積を大きくすることで、注出補助部材16,16´,16´をローラーR上で、より安定支持することができる。また、この例のように、開放部14aに対向する部分(薄肉部14b)も平坦にした場合は、更にローラーRとの接触面積が増えるため、安定支持することができる。   In particular, since the protrusions w1, w2, and w3 are plate-like members provided in a portion facing the open portion 14a, the contact area of the protrusions w1, w2, and w3 with the roller R surface is increased. The output auxiliary members 16, 16 ', 16' can be supported more stably on the roller R. Moreover, since the contact area with the roller R increases further when the part (thin wall part 14b) which opposes the open part 14a is also flat like this example, it can support stably.

このため、ローラーR上での注出補助部材16,16´,16´´の搬送速度を低下させることなく、注出補助部材16,16´,16´´を所定の長さで迅速に切断できる結果、注出補助部材16,16´,16´´および注出口付包装袋1の生産速度が上がり、注出口付包装袋1の生産効率を向上させることができる。   Therefore, the dispensing auxiliary members 16, 16 ′, 16 ″ are quickly cut to a predetermined length without reducing the conveying speed of the dispensing auxiliary members 16, 16 ′, 16 ″ on the roller R. As a result, the production speed of the extraction assisting members 16, 16 ′, 16 ″ and the packaging bag 1 with the spout increases, and the production efficiency of the packaging bag 1 with the spout can be improved.

なお、この突部を備える注出補助部材を、注出口3aを構成する積層フィルム4,4´の内側面に上述した成形金型15a,15b,15cを用いてヒートシールする際には、例えば、突出幅fが短く、注出口シール部9まで達しない突出幅fを有する突部w1を備えた注出補助部材16の場合、図13(a)に示すように、突部w1が注出補助部材16の外周縁部oに沿って外周縁部o中途部まで、注出補助部材16の外周面と積層フィルム4の内側面との間にヒートシールされる。   In addition, when heat-sealing the pouring auxiliary member provided with the protrusion using the above-described molding dies 15a, 15b, and 15c on the inner surface of the laminated films 4 and 4 ′ constituting the pouring port 3a, for example, In the case of the extraction assisting member 16 having the protrusion w1 having a protrusion width f that has a short protrusion width f and does not reach the spout seal portion 9, the protrusion w1 is discharged as shown in FIG. 13 (a). Heat sealing is performed between the outer peripheral surface of the extraction auxiliary member 16 and the inner surface of the laminated film 4 along the outer peripheral edge o of the auxiliary member 16 up to the middle portion of the outer peripheral edge o.

また、例えば、突出幅fが長く、注出口シール部9まで達する突出幅fを有する突部w2を備えた注出補助部材16´の場合、図13(b)に示すように、突部w2が、注出補助部材16の外周縁部oに沿って、注出補助部材16の外周面と積層フィルム4の内側面との間にヒートシールされるとともに、突部w2の先端部は、注出口シール部9中途部の積層フィルム4,4´内側面間にヒートシールされる。   Further, for example, in the case of the extraction assisting member 16 ′ having a protrusion w 2 having a long protrusion width f and a protrusion width f reaching the spout seal 9, as shown in FIG. 13B, the protrusion w 2. However, while being heat-sealed between the outer peripheral surface of the extraction auxiliary member 16 and the inner side surface of the laminated film 4 along the outer peripheral edge o of the extraction auxiliary member 16, the tip of the protrusion w2 is injected. Heat sealing is performed between the inner surfaces of the laminated films 4 and 4 ′ in the middle of the exit seal portion 9.

さらに、上述の図12〜図13に示したような注出補助部材16〜16´´では、開放部14aに対向する部分および突部w1〜w3の底部を平坦な形状(ローラRの接触面に水平となる水平面を有する)としているため、注出補助部材16〜16´´を、上述したように図示しない平坦な上下シールバーを使用し、該下シールバーを積層フィルム4の下面に位置させ、開放部14aから前記上シールバーを注出補助部材16〜16´´の開放部14aと対向する部分を含む突部w1〜w3の底部に押し当てて、この開放部14aと対向する部分を含む突部w1〜w3の底部を積層フィルム4の内側面に仮付けする際、双方平坦部分の押し当てにより、注出補助部材16〜16´´を積層フィルム4の内側面によりいっそう安定的に仮付けすることができる。   Further, in the extraction assisting members 16 to 16 ″ as shown in FIGS. 12 to 13 described above, the portion facing the opening 14a and the bottom of the protrusions w1 to w3 are flat (the contact surface of the roller R). As described above, the upper and lower sealing bars (not shown) are used as the pouring auxiliary members 16 to 16 ″, and the lower sealing bar is positioned on the lower surface of the laminated film 4. The upper seal bar is pressed against the bottom of the protrusions w1 to w3 including the portion facing the opening 14a of the extraction assisting members 16 to 16 ″ from the opening 14a, and the portion facing the opening 14a When temporarily attaching the bottoms of the protrusions w1 to w3 including the inner side surface of the laminated film 4 to the inner side surface of the laminated film 4 by pressing both flat portions, the dispensing auxiliary members 16 to 16 ″ are more stable. To attach to Can do.

そして、上記のように成形金型15b,15cを用いて注出補助部材16〜16´´を積層フィルム4,4´にヒートシール中に、注出補助部材16〜16´´が弾性体であるため、開放部14aの両近傍部分は、積層フィルム4´を介して成形金型15cの押圧に追従し、互いに近づく方向(外径が小さくなるように)に弾性変形することで開放部14aが略閉塞して開放部14a側の注出補助部材16〜16´´がシール成形されるとともに、弾性体である突部w1〜w2も積層フィルム4を介して成形金型15bに追従してシール成形される。このため、積層フィルム4,4´に掛かる引張力や外力を軽減させることで、積層フィルム4,4´の損傷や皺の発生を防止することができる。   Then, as described above, during the heat sealing of the pouring auxiliary members 16 to 16 ″ to the laminated films 4 and 4 ′ using the molding dies 15b and 15c, the pouring auxiliary members 16 to 16 ″ are elastic bodies. Therefore, both open portions 14a follow the pressing of the molding die 15c via the laminated film 4 'and elastically deform in the direction approaching each other (so that the outer diameter becomes small), thereby opening the open portion 14a. Is substantially closed and the discharge assisting members 16 to 16 ″ on the open portion 14 a side are sealed, and the protrusions w 1 to w 2 that are elastic bodies follow the molding die 15 b through the laminated film 4. Seal molded. For this reason, damage and generation | occurrence | production of a flaw can be prevented by reducing the tensile force and external force which are applied to laminated film 4, 4 '.

また、本願注出補助部材の突部は、図14に例示するような形状および取付位置にすることもできる。図14はローラー間における、円柱状部材からなる突部を開放部とは対向位置に2つ備える注出補助部材の断面側面図(a)、板状部材からなる突部を開放部とは対向位置に備える注出補助部材の断面側面図(b)、円柱状部材からなる突部を3つ備える注出補助部材の断面側面図(c)および円柱状部材からなる突部を開放部近傍に2つ備える注出補助部材の断面側面図(d)である。   Further, the protrusions of the application assisting member of the present application can have a shape and an attachment position as illustrated in FIG. FIG. 14 is a cross-sectional side view (a) of a dispensing auxiliary member provided with two protrusions made of a columnar member between the rollers at positions opposite to the opening part, and the protrusions made of a plate member facing the opening part. Cross-sectional side view (b) of the pouring auxiliary member provided at the position, cross-sectional side view (c) of the pouring auxiliary member provided with three protrusions made of the cylindrical member, and the protrusion made of the cylindrical member in the vicinity of the open portion It is a cross-sectional side view (d) of the extraction assistance member provided with two.

この場合、例えば(a)に例示すように、注出補助部材17aの開放部14aに対向する部分(薄肉部14b)に位置する両端の外周縁部oに、円柱状の突部w4を、注出補助部材17aの長さ方向に亘って設け、この突部w4を介してローラーR面上に注出補助部材17aを安定載置させてもよい。   In this case, for example, as illustrated in (a), columnar protrusions w4 are formed on the outer peripheral edge portions o at both ends located at the portion (thin wall portion 14b) facing the opening portion 14a of the dispensing auxiliary member 17a. It may be provided over the length direction of the extraction assisting member 17a, and the extraction assisting member 17a may be stably placed on the surface of the roller R via the protrusion w4.

また、(b)に例示すように、注出補助部材17bの開放部14aに対向する部分(薄肉部14b)の外周縁部oから外側方へ垂直向きに板状の突部w5を、注出補助部材17bの長さ方向に亘って設け設けることもできる。この場合、例えば、ローラーR内側の所定位置に規制部材18を設けてもよく、注出補助部材17bが転位しようとしても、突部w5が規制部材に接触して、注出補助部材17bの転位を防ぐため、ローラーR間で、注出補助部材17bの搬送姿勢を一定に保つことができる。   Further, as illustrated in (b), a plate-like protrusion w5 is poured vertically outwardly from the outer peripheral edge o of the portion (thin wall portion 14b) facing the open portion 14a of the dispensing auxiliary member 17b. It can also be provided over the length direction of the output assisting member 17b. In this case, for example, the regulating member 18 may be provided at a predetermined position inside the roller R, and even if the extraction assisting member 17b tries to shift, the protrusion w5 comes into contact with the regulating member and the shifting of the dispensing assisting member 17b. In order to prevent this, it is possible to keep the conveying posture of the dispensing auxiliary member 17b constant between the rollers R.

また、(c)に例示すように、注出補助部材17cの厚肉部14dにおける外周縁部oの所定位置に複数個所で円柱状の突部w6を、注出補助部材17cの長さ方向に亘って設けたり、あるいは(d)に例示すような注出補助部材17dの開放部14a近傍の両外周縁部oに円柱状の突部w7を、注出補助部材17dの長さ方向に亘って設けてもよく、上記同様にそれら突部w6または突部w7を介して注出補助部材17c,17dを安定載置し、注出補助部材17c,17dの搬送姿勢を一定に保つことができる。   Further, as illustrated in (c), columnar protrusions w6 are provided at predetermined positions on the outer peripheral edge o of the thick portion 14d of the extraction assisting member 17c at a plurality of positions, and the length direction of the extraction assisting member 17c. Or cylindrical protrusions w7 on both outer peripheral edges o in the vicinity of the opening 14a of the extraction assisting member 17d as shown in FIG. 4D in the length direction of the extraction assisting member 17d. In the same manner as described above, it is possible to stably place the extraction assisting members 17c and 17d via the projections w6 or the projections w7 and to keep the delivery posture of the extraction assisting members 17c and 17d constant. it can.

なお、これら突部w4〜w7は、上述した突部w1〜w3の材質および成形方法と同じものであり、また、その大きさも、ヒートシール性を阻害せずに注出補助部材17a〜17dの姿勢を一定に保ち、安定支持できる大きさに適宜することができるものであって、それら大きさおよび形状は限定されるものではない。   In addition, these protrusions w4 to w7 are the same as the material and molding method of the protrusions w1 to w3 described above, and the size of the protrusions 17a to 17d does not hinder the heat sealability. The posture can be kept constant and can be appropriately adjusted to a size that can be stably supported, and the size and shape are not limited.

従って、このような突部w4〜w7を備える注出補助部材17a〜17dにすることで、注出口付包装袋1の製造工程において、長尺の巻取状に作製しておいた注出補助部材17a〜17dを、ローラーR上で必要な長さに切断する際、突部w4〜w7を、ローラーR面に接触させることで、注出補助部材17a〜17dがローラーR上で安定な姿勢を保ち、開放部14aを一定方向に揃えて注出補助部材17a〜17dを搬送することができるため、ローラーR上での注出補助部材17a〜17dの搬送速度を低下させることなく、注出補助部材17a〜17dを所定の長さで迅速に切断できる結果、注出補助部材17a〜17dおよび注出口付包装袋1の生産速度が上がり、注出口付包装袋1の生産効率を向上させることができる。   Therefore, by using the extraction assisting members 17a to 17d provided with such protrusions w4 to w7, in the manufacturing process of the packaging bag 1 with an outlet, the extraction assisting prepared in a long winding shape is used. When cutting the members 17a to 17d to the required length on the roller R, the pouring auxiliary members 17a to 17d are in a stable posture on the roller R by bringing the protrusions w4 to w7 into contact with the roller R surface. , And the discharge assisting members 17a to 17d can be transported with the opening portion 14a aligned in a certain direction, so that it is possible to dispense without reducing the transport speed of the dispensing assisting members 17a to 17d on the roller R. As a result that the auxiliary members 17a to 17d can be quickly cut to a predetermined length, the production speed of the extraction auxiliary members 17a to 17d and the packaging bag 1 with a spout increases, and the production efficiency of the packaging bag 1 with a spout increases. Can do.

なお、この発明は、流動性を有する内容物を密閉包装し、注出口より内容物を注出させる、上述したスタンディングパウチのほか、平パウチでもよく、また、注出口部の位置や形状も限定されない、注出口部を備えるあらゆる包装袋に適用することができる。   In addition, the present invention may be a flat pouch in addition to the above-described standing pouch, in which the fluid content is hermetically packaged and the content is poured out from the spout, and the position and shape of the spout portion are also limited. Not applicable, it can be applied to any packaging bag having a spout portion.
