Description

縦型製袋充填包装機、内容物入り包装袋の製造方法、内容物入り包装袋Vertical bag filling and packaging machine, manufacturing method of packaging bag with contents, packaging bag with contents
　本発明は、縦型製袋充填包装機、内容物入り包装袋の製造方法、内容物入り包装袋に関する。 The present invention relates to a vertical bag-making filling and packaging machine, a method for manufacturing a packaging bag containing contents, and a packaging bag containing contents.
　食品を封入した包装袋が流通している。このような包装袋は、パウチ袋と呼ばれている。調理の手間を省くために、包装袋から食品を取り出すことなく、包装袋に封入されたままの状態で食品を電子レンジで加熱調理できるものもある。この包装袋には、電子レンジで加熱したときに発生する蒸気（内部圧力）を外部に逃がす蒸気抜き口が熱溶着シールに形成される。
　包装袋には、固形と液体が混合した食品（内容物）が封入されることが多い。 Packaging bags containing food are on the market. Such a packaging bag is called a pouch bag. In order to save the trouble of cooking, some foods can be cooked in a microwave oven while they are still enclosed in the packaging bag without removing the food from the packaging bag. In this packaging bag, a steam vent is formed in the heat welding seal to release steam (internal pressure) generated when heated in a microwave oven to the outside.
Foods (contents) that are a mixture of solids and liquids are often enclosed in packaging bags.
　食品を封入した包装袋には、スタンディングパウチと呼ばれる自立包装袋もある。自立包装袋は、立てた姿勢にして陳列棚に展示できるので、高いディスプレイ効果が得られる。自立包装袋は、立てた姿勢で袋上部から食品を取り出すことができるので、包装袋をそのまま食器（容器）として使用することもできる。 There is also a self-standing packaging bag called a standing pouch in the packaging bag that encloses food. Since the self-standing packaging bag can be displayed on the display shelf in an upright position, a high display effect can be obtained. Since the self-standing packaging bag can take out food from the upper part of the bag in an upright position, the packaging bag can be used as it is as tableware (container).
特開２０１８－０５８６０３号公報Japanese Unexamined Patent Publication No. 2018-058603 特開２００５－２３１７２２号公報Japanese Unexamined Patent Publication No. 2005-231722 特開２００１－２０６３０７号公報Japanese Unexamined Patent Publication No. 2001-206307
　特許文献１の自立包装袋では、その頂部の熱溶着シール（縦シール）に蒸気抜き口が形成される。この包装袋では、サイドシールになる部位を開口させて、内容物を投入（充填）する。しかし、縦シールやガセットを形成するときにサイドシールの一部も同時に形成しているため、内容物を充填する開口を大きく広げることが難しい。このため、内容物に固形物が含まれると、充填時間が長くなり製造効率が低下してしまう。 In the self-standing packaging bag of Patent Document 1, a steam vent is formed in the heat welding seal (vertical seal) at the top. In this packaging bag, the part to be the side seal is opened and the contents are charged (filled). However, since a part of the side seal is also formed at the same time when the vertical seal or the gusset is formed, it is difficult to greatly widen the opening for filling the contents. Therefore, if the content contains a solid substance, the filling time becomes long and the production efficiency decreases.
　特許文献２の包装袋では、サイドシールに沿う方向の中央に配置された背貼りシールに蒸気抜き口が形成される。この包装袋を電子レンジに平置きして加熱調理すると、包装袋の中央が大きく膨れ上がり、背貼りシールが包装袋の表面に向かって倒れて密着する。このため、蒸気抜き口が開口されづらくなり、内圧が高くなる。蒸気抜き口が開口するときの内圧（開口圧）が特許文献１，３等の包装袋に比べて２倍以上になってしまう。したがって、蒸気抜き口よりも先にサイドシールが破壊されてしまうおそれがある。
　特許文献２の包装袋では、内容物を取り出すときに、包装袋を立てた姿勢にして、包装袋を背貼りシールに沿う方向に切り裂いて開封口を形成する。しかし、包装袋を立てた姿勢にするときに、袋内で内容物（液面）が背貼りシールよりも高い位置に移動して、蒸気抜き口から高温の内容物（液体）が吹き出てしまうおそれがある。 In the packaging bag of Patent Document 2, a steam vent is formed in the backing seal arranged in the center in the direction along the side seal. When this packaging bag is placed flat in a microwave oven and cooked, the center of the packaging bag swells greatly, and the backing seal falls toward the surface of the packaging bag and adheres to it. For this reason, it becomes difficult to open the steam vent, and the internal pressure increases. The internal pressure (opening pressure) when the steam vent is opened is more than double that of the packaging bags of Patent Documents 1 and 3. Therefore, the side seal may be destroyed before the steam vent.
In the packaging bag of Patent Document 2, when the contents are taken out, the packaging bag is placed in an upright posture and the packaging bag is torn in the direction along the backing seal to form an opening. However, when the packaging bag is placed in an upright position, the contents (liquid level) move to a position higher than the backing seal inside the bag, and the high-temperature contents (liquid) are blown out from the steam vent. There is a risk.
　特許文献３では、サイドシールに沿う方向の端部に配置された背貼りシール（上端シール）に蒸気抜き口が形成される。この包装袋を電子レンジに平置きして加熱調理すると、包装袋の中央が大きく膨れ上がって、包装袋の姿勢が不安定になりやすい。このため、蒸気抜き口が袋内の内容物（液面）よりも低い位置に移動してしまい、蒸気抜き口から高温の内容物（液体）が吹き出てしまうおそれがある。 In Patent Document 3, a steam vent is formed in a backing seal (upper end seal) arranged at the end in the direction along the side seal. When this packaging bag is placed flat in a microwave oven and cooked by heating, the center of the packaging bag swells greatly, and the posture of the packaging bag tends to become unstable. Therefore, the vapor vent may move to a position lower than the contents (liquid level) in the bag, and the high temperature contents (liquid) may be blown out from the vapor vent.
　特許文献１－３では、包装袋を切り裂く際に開封口が曲がって形成されてしまうと、包装袋をそのまま容器として使用するときに見栄えが悪くなる等のおそれがある。
　特許文献２では、開封口の近傍に背貼りシールが存在するため、開封口が扁平に閉じやすく、包装袋から内容物を取り出しづらくなってしまう。スプーンやフォーク、箸等のカトラリー類を使って包装袋から内容物を取り出すことが難しくなってしまう。 According to Patent Document 1-3, if the opening is bent and formed when the packaging bag is torn, the appearance may be deteriorated when the packaging bag is used as it is as a container.
In Patent Document 2, since the backing seal exists in the vicinity of the opening, the opening is easily closed flat and it becomes difficult to take out the contents from the packaging bag. It becomes difficult to remove the contents from the packaging bag using cutlery such as spoons, forks, and chopsticks.
　本発明は、固形と液体が混合した内容物であっても効率的に封入でき、包装袋を切り裂く際に開封口を曲がらずに直線状に形成しやすい内容物入り包装袋、縦型製袋充填包装機、内容物入り包装袋の製造方法を提供することを目的とする。 INDUSTRIAL APPLICABILITY The present invention can efficiently enclose even a mixture of solid and liquid contents, and when tearing the packaging bag, it is easy to form a straight opening without bending the opening. It is an object of the present invention to provide a packaging machine and a method for manufacturing a packaging bag containing contents.
　本発明は、立てた姿勢にしてそのまま容器として使用するときに、内容物の取り出しやすい大きな開封口を形成できる内容物入り包装袋、縦型製袋充填包装機、内容物入り包装袋の製造方法を提供することを目的とする。 The present invention provides a packaging bag containing contents, a vertical bag-making filling packaging machine, and a method for manufacturing a packaging bag containing contents, which can form a large opening for easily taking out the contents when the contents are used as a container in an upright position. The purpose is to do.

〔第一実施形態：フィルム包装袋１００〕
　図１から図３は、第一実施形態に係る内容物入りフィルム包装袋１００を示す図である。図１は正面図、図２は加熱調理前の状態を示す斜視図、図３は加熱調理中の状態を示す斜視図である。 [First Embodiment: Film packaging bag 100]
1 to 3 are views showing a film packaging bag 100 containing contents according to the first embodiment. 1 is a front view, FIG. 2 is a perspective view showing a state before cooking, and FIG. 3 is a perspective view showing a state during cooking.
　フィルム包装袋（ピロー形包装袋）１００は、いわゆるピロー袋であって、帯状のフィルムＦを熱溶着（熱シール）して形成される。フィルム包装袋１００には、食品等の内容物Ｘが充填される。
　フィルム包装袋１００では、内容物Ｘを取り出すことなく、内容物Ｘが封入されたままの状態で電子レンジ等により加熱調理される。 The film packaging bag (pillow-shaped packaging bag) 100 is a so-called pillow bag, and is formed by heat-welding (heat-sealing) a strip-shaped film F. The film packaging bag 100 is filled with the contents X such as food.
In the film packaging bag 100, the contents X are not taken out and are cooked by heating in a microwave oven or the like with the contents X enclosed.
　フィルム包装袋１００のサイドシール１１０に沿う方向を長手方向（第一方向）という。
　フィルム包装袋１００の背貼りシール１２０に沿う方向（長手方向に直交する方向）を短手方向（第二方向）という。
　長手方向と短手方向に直交する方向を厚み方向（第三方向）という。 The direction along the side seal 110 of the film packaging bag 100 is called the longitudinal direction (first direction).
The direction along the backing seal 120 of the film packaging bag 100 (the direction orthogonal to the longitudinal direction) is referred to as the lateral direction (second direction).
The direction orthogonal to the longitudinal direction and the lateral direction is called the thickness direction (third direction).
　フィルム包装袋１００は、後述する縦型製袋充填包装機１により製袋されると同時に、内容物Ｘが充填される。
　フィルムＦは、ナイロンやポリエステル等の高強度フィルムを積層したラミネートフィルムである。フィルムＦは、内面同士が溶着するが、外面同士が溶着しないように各種フィルムが積層される。 The film packaging bag 100 is bag-made by the vertical bag-making filling and packaging machine 1 described later, and at the same time, the content X is filled.
The film F is a laminated film in which a high-strength film such as nylon or polyester is laminated. In the film F, various films are laminated so that the inner surfaces are welded to each other but the outer surfaces are not welded to each other.
　フィルム包装袋１００は、長手方向の長さが例えば２００ｍｍ、短手方向の長さが例えば１５０ｍｍである。フィルム包装袋１００の厚み方向の長さは、内容物Ｘの種類等により異なり、例えば１０～３０ｍｍである。
　フィルム包装袋１００には、空気を含まないように、内容物Ｘが充填される。フィルム包装袋１００の満注容量（最大充填量）に対する内容物Ｘの充填量の割合は、例えば５０～８０％である。 The film packaging bag 100 has a length in the longitudinal direction, for example, 200 mm, and a length in the lateral direction, for example, 150 mm. The length of the film packaging bag 100 in the thickness direction varies depending on the type of the content X and the like, and is, for example, 10 to 30 mm.
The film packaging bag 100 is filled with the content X so as not to contain air. The ratio of the filling amount of the content X to the full filling capacity (maximum filling amount) of the film packaging bag 100 is, for example, 50 to 80%.
　フィルム包装袋１００は、短手方向の両端にそれぞれサイドシール１１０を有する。サイドシール１１０は、フィルム包装袋１００において、長手方向の全長に亘って延在する。サイドシール１１０の幅（シール幅）は、例えば１２ｍｍである。
　フィルム包装袋１００の長手方向の両端（第一端１０３および第二端１０４）は、フィルムＦが折り返される（フィルムＦの内面同士が対向する外折り）。第一端１０３および第二端１０４は、折り端とも呼ばれる。 The film packaging bag 100 has side seals 110 at both ends in the lateral direction. The side seal 110 extends over the entire length in the longitudinal direction in the film packaging bag 100. The width (seal width) of the side seal 110 is, for example, 12 mm.
The film F is folded back at both ends (first end 103 and second end 104) of the film packaging bag 100 in the longitudinal direction (outer folding with the inner surfaces of the film F facing each other). The first end 103 and the second end 104 are also referred to as folded ends.
　フィルム包装袋１００は、表面１０１に背貼りシール１２０を有する。背貼りシール１２０は、短手方向の全長に亘って延在する。背貼りシール１２０の幅（シール幅）は、例えば１０ｍｍである。
　背貼りシール１２０は、長手方向の中央Ｃよりも第一端１０３側（中央Ｃと第一端１０３の間）に配置される。具体的には、背貼りシール１２０は、第一端１０３から第二端１０４側に１０～９０ｍｍの位置に配置される。
　特に、背貼りシール１２０は、長手方向の中央Ｃと第一端１０３のほぼ中間に配置される。具体的には、背貼りシール１２０は、第一端１０３から第二端１０４側に４０～６０ｍｍの位置に配置される。例えば、背貼りシール１２０は、第一端１０３から第二端１０４側に５０ｍｍの位置に配置される。
　背貼りシール１２０の両端は、それぞれサイドシール１１０に接続する。背貼りシール１２０は、第一端１０３側に折り倒される。背貼りシール１２０は、サイドシール１１０に溶着されないため、表面１０１から離して立てることができる。 The film packaging bag 100 has a backing seal 120 on the surface 101. The backing seal 120 extends over the entire length in the lateral direction. The width (seal width) of the backing seal 120 is, for example, 10 mm.
The backing seal 120 is arranged on the side of the first end 103 (between the center C and the first end 103) with respect to the center C in the longitudinal direction. Specifically, the backing seal 120 is arranged at a position of 10 to 90 mm from the first end 103 to the second end 104 side.
In particular, the backing seal 120 is arranged substantially in the middle between the center C in the longitudinal direction and the first end 103. Specifically, the backing seal 120 is arranged at a position of 40 to 60 mm from the first end 103 to the second end 104 side. For example, the backing seal 120 is arranged at a position of 50 mm from the first end 103 to the second end 104 side.
Both ends of the backing seal 120 are connected to the side seal 110, respectively. The backing seal 120 is folded down toward the first end 103 side. Since the back seal 120 is not welded to the side seal 110, it can be erected away from the surface 101.
　サイドシール１１０の第一端１０３側には、切り裂き用のノッチ（開封用ノッチ）１１２が設けられる。ノッチ１１２は、背貼りシール１２０よりも第二端１０４側に配置される。ノッチ１１２は、背貼りシール１２０から第二端１０４側に約１０～１２ｍｍ程度の範囲内に配置される。
　このノッチ１１２を起点にしてフィルムＦを切り裂いて、フィルム包装袋１００の第一端１０３側を短手方向に沿って切り落とす。フィルム包装袋１００を短手方向に沿って切り取ることで、フィルム包装袋１００に開封口Ｐ（図９参照）が形成される。
　開封口Ｐを形成するときに、ノッチ１１２よりも上方側の部位を完全に切り取ってもよいし、ノッチ１１２よりも上方側の部位を切り取らずにフィルム包装袋１００の一部（側部）を切り裂くだけでもよい。 A notch (opening notch) 112 for tearing is provided on the 103 side of the first end of the side seal 110. The notch 112 is arranged on the second end 104 side of the backing seal 120. The notch 112 is arranged within a range of about 10 to 12 mm from the backing seal 120 to the second end 104 side.
The film F is torn from the notch 112 as a starting point, and the first end 103 side of the film packaging bag 100 is cut off along the lateral direction. By cutting the film packaging bag 100 along the lateral direction, an opening P (see FIG. 9) is formed in the film packaging bag 100.
When forming the opening P, the portion above the notch 112 may be completely cut off, or a part (side portion) of the film packaging bag 100 may be cut off without cutting off the portion above the notch 112. You can just tear it apart.
　サイドシール１１０の第一端１０３側には、加熱調理後のフィルム包装袋１００を把持する把持領域１１５が設けられる。把持領域１１５は、ノッチ１１２と背貼りシール１２０の間に配置される。背貼りシール１２０、把持領域１１５、ノッチ１１２が、長手方向（第一方向）において、ほぼ隙間なく近接して配置される。
　把持領域１１５は、サイドシール１１０の一部に印刷を施すことにより指示（設定）されている。把持領域１１５は、背貼りシール１２０の直下（第二端１０４側）に配置されている。把持領域１１５は、背貼りシール１２０から第二端１０４側に約０～１０ｍｍ程度の範囲に設定される。把持領域１１５の一部（第一端１０３側）が背貼りシール１２０に重なるように設定してもよい。把持領域１１５の幅を他のサイドシール１１０の幅よりも大きく形成してもよい。 A gripping region 115 for gripping the film packaging bag 100 after cooking is provided on the first end 103 side of the side seal 110. The grip area 115 is arranged between the notch 112 and the backing seal 120. The backing seal 120, the gripping area 115, and the notch 112 are arranged in close proximity to each other in the longitudinal direction (first direction) with almost no gap.
The gripping area 115 is instructed (set) by printing a part of the side seal 110. The gripping region 115 is arranged directly below the backing seal 120 (on the side of the second end 104). The gripping area 115 is set in a range of about 0 to 10 mm from the backing seal 120 to the second end 104 side. A part of the gripping area 115 (on the side of the first end 103) may be set so as to overlap the backing seal 120. The width of the grip area 115 may be formed larger than the width of the other side seal 110.
　背貼りシール１２０には、蒸気口（蒸気抜き部）１２５が設けられる。蒸気口１２５は、短手方向の中央に配置される。蒸気口１２５は、フィルム包装袋１００を電子レンジで加熱すると開口する。蒸気口１２５は、フィルム包装袋１００の内部圧力の上昇に伴って開口する。具体的には、内容物Ｘから蒸気が発生すると、フィルム包装袋１００の内圧が上昇して背貼りシール１２０の一部分に応力が集中する。そして、この一部分のシール（熱溶着）が破れて、蒸気口１２５が開口する。
　蒸気口１２５は、消費者が背貼りシール１２０の一部を切り裂く等して開口させてもよい。 The backing seal 120 is provided with a steam port (steam venting portion) 125. The steam port 125 is arranged in the center in the lateral direction. The steam port 125 opens when the film packaging bag 100 is heated in a microwave oven. The steam port 125 opens as the internal pressure of the film packaging bag 100 increases. Specifically, when steam is generated from the content X, the internal pressure of the film packaging bag 100 rises and stress is concentrated on a part of the backing seal 120. Then, the seal (heat welding) of this part is broken, and the steam port 125 opens.
The steam port 125 may be opened by the consumer by tearing a part of the backing seal 120 or the like.
　内容物Ｘは、固体（固形物）、液体または液体と固体の混合物である。液体には、ペースト体やジェル体も含まれる。内容物Ｘは、例えば食品であり、スープと具材（肉類や野菜、麺類）、水と米等である。内容物Ｘは、例えば、豚汁、肉じゃが、モツ煮、豚角煮、煮物、汁物である。
　フィルム包装袋１００は、ピロー袋であるため、内容物Ｘに大きな固形物が含まれる場合であっても、円滑かつ効率的に充填される。 The content X is a solid (solid), liquid or a mixture of liquid and solid. The liquid also includes a paste body and a gel body. The content X is, for example, food, soup and ingredients (meat, vegetables, noodles), water, rice, and the like. The content X is, for example, pork soup, meat potato, motsuni, pork kakuni, simmered dish, and soup.
Since the film packaging bag 100 is a pillow bag, the film packaging bag 100 is smoothly and efficiently filled even when the content X contains a large solid substance.
　上述したように、フィルム包装袋１００では、内容物Ｘを取り出すことなく、内容物Ｘが封入されたままの状態で電子レンジ等により加熱調理される。フィルム包装袋１００は、内容物Ｘを加熱調理するとき、平置きされる。フィルム包装袋１００は、背貼りシール１２０のある面（表面１０１）を上方に向けて平置きされる。 As described above, in the film packaging bag 100, the contents X are not taken out and are cooked by heating in a microwave oven or the like with the contents X enclosed. The film packaging bag 100 is laid flat when the content X is cooked. The film packaging bag 100 is laid flat with the side (surface 101) of the backing seal 120 facing upward.
　フィルム包装袋１００は、内容物Ｘが加熱調理されると、内圧上昇により膨れ上がる。特に、フィルム包装袋１００の中央付近の厚みが大幅に増加する（表面１０１、裏面１０２が大きく湾曲する）。 When the content X is cooked, the film packaging bag 100 swells due to an increase in internal pressure. In particular, the thickness near the center of the film packaging bag 100 is significantly increased (the front surface 101 and the back surface 102 are greatly curved).
　フィルム包装袋１００が膨れ上がると背貼りシール１２０も湾曲する。しかし、背貼りシール１２０は、長手方向の中央Ｃよりも第一端１０３側に配置されているため、中央付近よりも湾曲が小さい（曲率が小さい）。このため、背貼りシール１２０は、第一端１０３側に折り倒されている状態から表面１０１から離間するように自然に立ち上がる。これにより、蒸気口１２５に内圧がかかりやすくなる。そして、フィルム包装袋１００の内圧が過度に上昇することなく、蒸気口１２５が円滑に開口して、蒸気が噴き出る。 When the film packaging bag 100 swells, the backing seal 120 also bends. However, since the backing seal 120 is arranged on the first end 103 side of the center C in the longitudinal direction, the curvature is smaller (the curvature is smaller) than in the vicinity of the center. Therefore, the backing seal 120 naturally stands up so as to be separated from the surface 101 from the state of being folded down toward the first end 103 side. As a result, internal pressure is likely to be applied to the steam port 125. Then, the steam port 125 smoothly opens and steam is ejected without the internal pressure of the film packaging bag 100 rising excessively.
　フィルム包装袋１００は、内容物Ｘに液体が多い場合であっても、平置きの状態で加熱調理することができる。
　上述したように、フィルム包装袋１００は、表面１０１を上方に向けて平置きされ、内容物Ｘが加熱調理されると、内容物Ｘから蒸気が発生し、内圧上昇により膨れ上がる。
　フィルム包装袋１００が膨れ上がったとき、フィルム包装袋１００の姿勢が不安定になる。特に、フィルム包装袋１００が短手方向に転倒（回転）しやすくなる。しかし、サイドシール１１０がフィルム包装袋１００の短手方向に突出しているので、短手方向への転倒を防止するストッパーとして機能する。そして、フィルム包装袋１００の表面１０１側に蒸気が溜まり、背貼りシール１２０の蒸気口１２５が開口する。蒸気は、蒸気口１２５から上方向に向けて噴出する。
　このため、フィルム包装袋１００を平置きした状態で内容物Ｘを加熱調理しても、蒸気口１２５から内容物Ｘ（特に液体）が吹きこぼれづらい。 The film packaging bag 100 can be cooked in a flat state even when the content X contains a large amount of liquid.
As described above, the film packaging bag 100 is placed flat with the surface 101 facing upward, and when the content X is cooked, steam is generated from the content X and the film packaging bag 100 swells due to an increase in internal pressure.
When the film packaging bag 100 swells, the posture of the film packaging bag 100 becomes unstable. In particular, the film packaging bag 100 tends to tip over (rotate) in the lateral direction. However, since the side seal 110 protrudes in the lateral direction of the film packaging bag 100, it functions as a stopper for preventing the film packaging bag 100 from tipping over in the lateral direction. Then, steam collects on the surface 101 side of the film packaging bag 100, and the steam port 125 of the backing seal 120 opens. The steam is ejected upward from the steam port 125.
Therefore, even if the content X is cooked by heating with the film packaging bag 100 placed flat, the content X (particularly liquid) is unlikely to spill out from the steam port 125.
　内容物Ｘに液体が少ない場合も、フィルム包装袋１００を平置きの状態で内容物Ｘが加熱するのが好ましい。例えば、内容物Ｘが固体やペースト、ジェルの場合である。
　フィルム包装袋１００を平置きすると内容物Ｘが水平方向に広がって、フィルム包装袋１００の厚みが薄くなる。このため、内容物Ｘに熱が伝わりやすくなり、内容物Ｘの加熱時間を短縮することができる。 Even when the content X contains a small amount of liquid, it is preferable that the content X heats the film packaging bag 100 in a flat state. For example, when the content X is a solid, a paste, or a gel.
When the film packaging bag 100 is placed horizontally, the contents X expand in the horizontal direction, and the thickness of the film packaging bag 100 becomes thin. Therefore, heat is easily transferred to the content X, and the heating time of the content X can be shortened.
　図４は、内容物入りフィルム包装袋１００の開封中の状態を示す図である。
　フィルム包装袋１００は、内容物Ｘを取り出す開封口Ｐを形成するとき、立てた姿勢で消費者に把持される。フィルム包装袋１００は、第一端１０３側が上方になるように把持される。フィルム包装袋１００には高温になった内容物Ｘが封入されているため、フィルム包装袋１００は、サイドシール１１０の把持領域１１５を指でつままれて把持される。
　蒸気口１２５が開口したフィルム包装袋１００を立てた姿勢にしたときに、内容物Ｘ（液面）が背貼りシール１２０よりも下方に位置するように充填されている。好ましくは、フィルム包装袋１００を立てた姿勢にしたときに、内容物Ｘがノッチ１１２よりも下方に位置するように充填されている。
　消費者が把持領域１１５を指でつまんでフィルム包装袋１００を支持すると、指が背貼りシール１２０に触れて、背貼りシール１２０（蒸気口１２５）が上方（第一端１０３側）を向く姿勢になる。したがって、蒸気口１２５から高温の内容物Ｘ（特に液体）が漏れ出すことなく、火傷を回避できる。 FIG. 4 is a diagram showing a state in which the film packaging bag 100 containing the contents is being opened.
The film packaging bag 100 is held by the consumer in an upright posture when forming the opening P for taking out the contents X. The film packaging bag 100 is gripped so that the first end 103 side faces upward. Since the high temperature content X is enclosed in the film packaging bag 100, the film packaging bag 100 is gripped by pinching the gripping region 115 of the side seal 110 with a finger.
When the film packaging bag 100 with the steam port 125 opened is placed in an upright position, the content X (liquid level) is filled so as to be located below the backing seal 120. Preferably, the content X is filled so as to be located below the notch 112 when the film packaging bag 100 is placed in an upright position.
When the consumer pinches the grip area 115 with his / her fingers to support the film packaging bag 100, the finger touches the back sticker seal 120, and the back sticker seal 120 (steam port 125) faces upward (first end 103 side). become. Therefore, the high temperature content X (particularly the liquid) does not leak from the steam port 125, and burns can be avoided.
　サイドシール１１０には、把持領域１１５の直下（第二端１０４側）にノッチ１１２が設けられる。このため、消費者は、把持領域１１５を例えば右手の親指と人差し指でつまみながら、さらにノッチ１１２の下方側のサイドシール１１０も左手の親指と人差し指でつまむ。そして、両手を前後方向に離間させる（相反する方向に移動する）ことにより、ノッチ１１２を起点にしてフィルムＦを切り裂くことができる。
　このとき、把持領域１１５の直上（第一端１０３側）に背貼りシール１２０が配置されているため、消費者の力（フィルムＦを切り裂く力）が背貼りシール１２０を介して開封口Ｐ（裂け目）の先端に効率よく伝わる。消費者が把持領域１１５を指（例えば右手の親指と人差し指）でつまむと、必然的に背貼りシール１２０の短手方向の端部もつまんでしまうからである。背貼りシール１２０はフィルムＦ同士を熱溶着しているため、フィルムＦ自体よりも硬くなっているからである。
　したがって、開封口Ｐが背貼りシール１２０に沿って真っすぐに形成される。開封口Ｐが途中で下方向に曲がらずに、背貼りシール１２０に対してほぼ平行に形成される。これにより、開封中に内容物Ｘが開封口Ｐからこぼれ落ちて火傷をするおそれがない。 The side seal 110 is provided with a notch 112 directly below the grip region 115 (on the side of the second end 104). Therefore, the consumer pinches the gripping area 115 with, for example, the thumb and index finger of the right hand, and further pinches the side seal 110 on the lower side of the notch 112 with the thumb and index finger of the left hand. Then, by separating both hands in the front-rear direction (moving in opposite directions), the film F can be torn from the notch 112 as a starting point.
At this time, since the backing seal 120 is arranged directly above the gripping area 115 (on the side of the first end 103), the consumer's force (force to cut through the film F) is applied to the opening P (the force to cut through the film F) through the backing seal 120. Efficiently transmitted to the tip of the crevice). This is because when the consumer pinches the grip area 115 with fingers (for example, the thumb and index finger of the right hand), the end of the backing seal 120 in the lateral direction is inevitably pinched. This is because the backing seal 120 is harder than the film F itself because the films F are heat-welded to each other.
Therefore, the opening P is formed straight along the backing seal 120. The opening P is formed substantially parallel to the backing seal 120 without bending downward in the middle. As a result, there is no risk of the contents X spilling from the opening P during opening and causing burns.
　内容物Ｘ（液面）がノッチ１１２よりも下方に位置するように充填されている場合は、内容物Ｘをこぼすことなく、ノッチ１１２よりも上方側の部位を完全に切り取って開封口Ｐを形成することができる。これにより、火傷をすることなく、内容物Ｘを開封口Ｐから良好に取り出すことができる。
　内容物Ｘが背貼りシール１２０の直下まで充填されている場合は、フィルム包装袋１００を立てた姿勢から傾けて開封口Ｐを形成する。例えば右側のノッチ１１２が左側のノッチ１１２よりも上方になるようにフィルム包装袋１００を傾けて、内容物Ｘを右側のノッチ１１２よりも下方に移動させる（内容物Ｘを左側のノッチ１１２よりも上方に移動させる）。そして、右側のノッチ１１２からフィルム包装袋１００の側部を切り裂いて、内容物Ｘをこぼすことなく、開封口Ｐを形成する。これにより、火傷をすることなく、内容物Ｘを開封口Ｐから良好に取り出すことができる。 When the content X (liquid level) is filled so as to be located below the notch 112, the portion above the notch 112 is completely cut off without spilling the content X, and the opening P is opened. Can be formed. As a result, the content X can be satisfactorily taken out from the opening P without causing burns.
When the content X is filled up to just below the backing seal 120, the film packaging bag 100 is tilted from the upright position to form the opening P. For example, the film packaging bag 100 is tilted so that the notch 112 on the right side is above the notch 112 on the left side, and the content X is moved below the notch 112 on the right side (the content X is moved below the notch 112 on the left side). Move it upwards). Then, the side portion of the film packaging bag 100 is cut from the notch 112 on the right side to form the opening P without spilling the content X. As a result, the content X can be satisfactorily taken out from the opening P without causing burns.

The cutter portion 70 includes a cutter 72 and a cutter receiving groove (not shown). The cutter 72 is provided in the heater bar 62 on the front side, and the cutter receiving groove is provided in the heater bar 62 on the rear side.
The cutter portion 70 cuts the side seal 110 formed on the tube film Fc over the entire length in the left-right direction. As a result, the film packaging bag 100 is cut off from the tube film Fc.
　縦型製袋充填包装機１は、フィルム包装袋１００を製袋し、内容物Ｘをフィルム包装袋１００に充填する。フィルム包装袋１００がピロー袋であるため、例えば内容物Ｘに直径３０ｍｍ程度の固形物が含まれる場合であっても、フィルム包装袋１００に内容物Ｘを円滑かつ効率的に充填することができる。
　特に、縦型製袋充填包装機１は、背貼りシール１２０が長手方向の中央Ｃと第一端１０３の間に配置された内容物入りフィルム包装袋１００を連続して製造することができる。 The vertical bag-making filling and packaging machine 1 creates a film packaging bag 100 and fills the content X in the film packaging bag 100. Since the film packaging bag 100 is a pillow bag, for example, even when the content X contains a solid substance having a diameter of about 30 mm, the film packaging bag 100 can be smoothly and efficiently filled with the content X. ..
In particular, the vertical bag-making filling and packaging machine 1 can continuously manufacture a film packaging bag 100 containing contents in which the backing seal 120 is arranged between the center C in the longitudinal direction and the first end 103.
　セーラー部１１は、中心軸Ｊを基準にして、真正面（装置正面）から時計周りと反時計周りにそれぞれ９０°まで回転させた位置（姿勢）に配置（設定）される（図７参照）。これに伴い、搬入回転方向転換部９０（第一ローラー９１、第二ローラー９２）の設置角度が変更される。
　例えば、セーラー部１１が装置正面から時計周りに３０°回転した位置（姿勢）に配置された場合には、第一ローラー９１が装置背面から時計周りに１５°回転させた位置、第二ローラー９２が装置背面から時計周りにさらに１５°回転させた位置に配置される。
　例えば、セーラー部１１が装置正面から時計周りに６０°回転した位置（姿勢）に配置された場合には、第一ローラー９１が装置背面から時計周りに３０°回転させた位置、第二ローラー９２が装置背面から時計周りにさらに３０°回転させた位置に配置される。
　このように、第一ローラー９１、第二ローラー９２は、セーラー部１１の中心軸Ｊ周りの回転角度をローラー本数（２本）で均等割した角度で互いに交差するように配置される。 The sailor unit 11 is arranged (set) at a position (posture) rotated clockwise and counterclockwise by 90 ° from the front (front of the device) with respect to the central axis J (see FIG. 7). Along with this, the installation angle of the carry-in rotation direction changing portion 90 (first roller 91, second roller 92) is changed.
For example, when the sailor unit 11 is arranged at a position (posture) rotated 30 ° clockwise from the front of the device, the first roller 91 is rotated 15 ° clockwise from the back of the device, the second roller 92. Is placed at a position further rotated 15 ° clockwise from the back of the device.
For example, when the sailor unit 11 is arranged at a position (posture) rotated by 60 ° clockwise from the front of the device, the first roller 91 is rotated by 30 ° clockwise from the back of the device, the second roller 92. Is placed at a position further rotated 30 ° clockwise from the back of the device.
In this way, the first roller 91 and the second roller 92 are arranged so as to intersect each other at an angle obtained by evenly dividing the rotation angle around the central axis J of the sailor portion 11 by the number of rollers (2).
　図７に示すように、セーラー部１１の中心軸Ｊ周りの回転角度は、装置正面から時計周りまたは反時計周りに２０°から７５°の範囲が好ましい。さらに、４０°から６０°の範囲が好ましい。特に、４５°から５５°が好ましい。
　セーラー部１１の中心軸Ｊ周りの回転角度を調整して、背貼りシール１２０の第一方向の位置を設定する。そして、フィルム包装袋１００を第一端１０３が上方になるように立てた姿勢にしたときに、背貼りシール１２０よりも下方側（第二端１０４側）に内容物Ｘが位置するようにする。
　好ましくは、フィルム包装袋１００を立てた姿勢にしたときに、内容物Ｘがノッチ１１２よりも下方側に位置するように、背貼りシール１２０の第一方向の位置を設定する。
　内容物Ｘの充填量に対応して、背貼りシール１２０とノッチ１１２の第一方向の位置を調整してもよし、逆に背貼りシール１２０とノッチ１１２の第一方向の位置に対応して、内容物Ｘの充填量（充填率）を調整してもよい。 As shown in FIG. 7, the rotation angle of the sailor portion 11 around the central axis J is preferably in the range of 20 ° to 75 ° clockwise or counterclockwise from the front of the apparatus. Further, a range of 40 ° to 60 ° is preferable. In particular, 45 ° to 55 ° is preferable.
The rotation angle around the central axis J of the sailor portion 11 is adjusted to set the position of the backing seal 120 in the first direction. Then, when the film packaging bag 100 is placed in an upright position with the first end 103 facing upward, the content X is positioned below the backing seal 120 (second end 104 side). ..
Preferably, the position of the backing seal 120 in the first direction is set so that the content X is located below the notch 112 when the film packaging bag 100 is placed in an upright position.
The positions of the backing seal 120 and the notch 112 in the first direction may be adjusted according to the filling amount of the content X, and conversely, the positions of the backing seal 120 and the notch 112 in the first direction may be adjusted. , The filling amount (filling rate) of the content X may be adjusted.
　図８は、ツイストセーラーのセーラー部１１Ｔを示す正面図である。
　製袋ガイド１０のセーラー部１１は、ツイストセーラーとも呼ばれるセーラー部１１Ｔを用いてもよい。
　ツイストセーラーのセーラー部１１Ｔは、上流側（平板状の部位）が縦型製袋充填包装機１の真後ろ（装置背面）を向く。一方、このセーラー部１１Ｔの正面は、縦型製袋充填包装機１の正面ではなく、左斜め前方（正面から左側に４５°回転した位置）を向く。ツイストセーラー（セーラー部１１Ｔ）を用いた場合には、搬入回転方向転換部９０が不要になる。 FIG. 8 is a front view showing the sailor portion 11T of the twist sailor.
As the sailor portion 11 of the bag making guide 10, a sailor portion 11T, which is also called a twist sailor, may be used.
The upstream side (flat plate-shaped portion) of the sailor portion 11T of the twist sailor faces directly behind the vertical bag-making filling / packaging machine 1 (the back surface of the device). On the other hand, the front surface of the sailor portion 11T is not the front surface of the vertical bag-making filling / packaging machine 1, but faces diagonally forward to the left (position rotated by 45 ° from the front to the left side). When a twist sailor (sailor unit 11T) is used, the carry-in rotation direction changing unit 90 becomes unnecessary.
〔内容物入りフィルム包装袋１００の製造方法〕
　次に、縦型製袋充填包装機１を用いて、内容物入りフィルム包装袋１００を製造する工程について説明する。 [Manufacturing method of film packaging bag 100 containing contents]
Next, a process of manufacturing the film packaging bag 100 containing the contents by using the vertical bag-making filling and packaging machine 1 will be described.
　内容物入りフィルム包装袋１００を製造する工程は、製袋ガイド工程Ｓ１、フィルム搬送工程Ｓ２、背貼りシール工程Ｓ３（サイドシール工程Ｓ６）、内容物充填工程Ｓ４、矯正工程Ｓ５、サイドシール工程Ｓ６（背貼りシール工程Ｓ３）、袋体切離工程Ｓ７の順に、繰り返し行われる。 The steps for manufacturing the content-containing film packaging bag 100 include a bag making guide step S1, a film transfer step S2, a backing sealing step S3 (side sealing step S6), a content filling step S4, a straightening step S5, and a side sealing step S6 ( The backing sealing step S3) and the bag body cutting step S7 are repeated in this order.
〈製袋ガイド工程Ｓ１〉
　製袋ガイド工程Ｓ１は、製袋ガイド１０が帯状のフィルムＦをチューブ状に折り込む工程である。
　製袋ガイド１０は、フィルム供給部５から供給されたフィルムＦに密着して、フィルムＦをチューブ状に折り込む。
　製袋ガイド１０は、搬送方向を前方向から下方向に方向転換して、チューブ状のフィルムＦ（チューブフィルムＦｃ）を下方向に吊り下げた状態で保持する。そして、フィルムＦは、縦型製袋充填包装機１の正面左側（斜め前方）において、その側縁同士が密着する。 <Bag making guide process S1>
The bag-making guide step S1 is a step in which the bag-making guide 10 folds the strip-shaped film F into a tube shape.
The bag making guide 10 is in close contact with the film F supplied from the film supply unit 5, and the film F is folded into a tube shape.
The bag making guide 10 changes the transport direction from the front direction to the downward direction, and holds the tube-shaped film F (tube film Fc) in a state of being suspended downward. The side edges of the film F are in close contact with each other on the front left side (obliquely forward) of the vertical bag-making filling and packaging machine 1.
〈フィルム搬送工程Ｓ２〉
　フィルム搬送工程Ｓ２は、フィルム搬送部（不図示）がチューブ状のフィルムＦ（チューブフィルムＦｃ）を間欠搬送する工程である。
　フィルム搬送部は、複数の搬送ローラーを回転させて、チューブフィルムＦｃを下方に搬送する。フィルム搬送部によるチューブフィルムＦｃの間欠搬送量（フィルム搬送量）は、フィルム包装袋１００の短手方向の長さ（例えば１５０ｍｍ）と同一である。 <Film transfer process S2>
The film transport step S2 is a step in which the film transport unit (not shown) intermittently transports the tubular film F (tube film Fc).
The film transport unit rotates a plurality of transport rollers to transport the tube film Fc downward. The intermittent transfer amount (film transfer amount) of the tube film Fc by the film transfer unit is the same as the length (for example, 150 mm) in the lateral direction of the film packaging bag 100.
〈背貼りシール工程Ｓ３〉
　背貼りシール工程Ｓ３は、背貼りシール部３０がチューブ状に折り込まれたフィルムＦに背貼りシール１２０を形成する工程である。
　背貼りシール工程Ｓ３は、フィルムＦが停止しているときに行われる。背貼りシール工程Ｓ３は、フィルム搬送工程Ｓ２とは異なるタイミングで行われる。背貼りシール工程Ｓ３と同時に、サイドシール工程Ｓ６が行われる。
　背貼りシール部３０は、一対のヒーターバー３１の間に挿入されたフィルムＦの側縁同士を熱溶着する。そして、フィルム搬送部がチューブフィルムＦｃを下方に搬送することにより、背貼りシール１２０が隙間なく連続して形成される。 <Back pasting seal process S3>
The backing seal step S3 is a step of forming the backing seal 120 on the film F in which the backing sealing portion 30 is folded into a tube shape.
The backing sealing step S3 is performed when the film F is stopped. The backing sealing step S3 is performed at a timing different from that of the film transporting step S2. The side sealing step S6 is performed at the same time as the backing sealing step S3.
The backing seal portion 30 heat-welds the side edges of the film F inserted between the pair of heater bars 31. Then, the film transport portion transports the tube film Fc downward, so that the backing seal 120 is continuously formed without a gap.
〈内容物充填工程Ｓ４〉
　内容物充填工程Ｓ４は、充填部４０がチューブフィルムＦｃの内部に内容物Ｘを投入する工程である。充填部４０は、いわゆる２パート充填を行う。充填部４０は、ノズル（不図示）から液体（内容物Ｘ）を吐出する。パイプ部１２とノズルの間に固形物（内容物Ｘ）を投入する。これにより、チューブフィルムＦｃの内部に、液体と固形物を含む内容物Ｘが供給される。
　チューブフィルムＦｃの内部に投入される内容物Ｘの量（充填量）は、所定量に設定（調整）される。具体的には、内容物Ｘが封入されたフィルム包装袋１００を、第一端１０３が上方になるように立てた姿勢にしたときに、内容物Ｘが背貼りシール１２０（好ましくはノッチ１１２）よりも下方側（第二端１０４側）になるように設定される。フィルム包装袋１００の満注容量（最大充填量）に対する内容物Ｘの充填量の割合は、例えば５０～８０％である。 <Content filling step S4>
The content filling step S4 is a step in which the filling portion 40 puts the content X into the inside of the tube film Fc. The filling unit 40 performs so-called two-part filling. The filling unit 40 discharges a liquid (content X) from a nozzle (not shown). A solid substance (content X) is charged between the pipe portion 12 and the nozzle. As a result, the content X containing the liquid and the solid is supplied to the inside of the tube film Fc.
The amount (filling amount) of the content X charged into the tube film Fc is set (adjusted) to a predetermined amount. Specifically, when the film packaging bag 100 in which the content X is enclosed is placed in an upright posture with the first end 103 facing upward, the content X is a backing seal 120 (preferably a notch 112). It is set to be on the lower side (second end 104 side). The ratio of the filling amount of the content X to the full filling capacity (maximum filling amount) of the film packaging bag 100 is, for example, 50 to 80%.
〈矯正工程Ｓ５〉
　矯正工程Ｓ５は、内容物Ｘが投入されたチューブフィルムＦｃを矯正部５０が前後方向から挟持・扱く工程である。
　矯正部５０は、チューブフィルムＦｃに内容物Ｘが十分に充填されると、一対の矯正板５４によりチューブフィルムＦｃを前後方向から押圧する。これにより、チューブフィルムＦｃの底部に充填された内容物Ｘが押し上げられる。矯正板５４は、内容物Ｘが充填されて膨張したチューブフィルムＦｃ（フィルム包装袋１００）を一定の厚みに矯正する。
　矯正板５４がチューブフィルムＦｃの形状を矯正すると、内容物Ｘがシゴキローラー５２よりも上方まで押し上げられて、内容物Ｘに含まれていた空気がシゴキローラー５２よりも上方に移動する。これにより、チューブフィルムＦｃの下方側には、空気を含まない内容物Ｘが配置（充填）される。
　そして、矯正部５０は、一対のシゴキローラー５２によりチューブフィルムＦｃを前後方向から搾る。矯正部５０は、一対のシゴキローラー５２を密着させてシゴキローラー５２を挟持して、内容物Ｘを上下方向に分断する。
　これにより、チューブフィルムＦｃが封緘されて、シゴキローラー５２の直下に、内容物Ｘのみが充填された袋体（上端が未封止のフィルム包装袋１００）が出現する。
　一対のシゴキローラー５２が密着したら、矯正板５４をチューブフィルムＦｃから離間させる。一対のシゴキローラー５２は、サイドシール工程Ｓ６が終了するまで、チューブフィルムＦｃを封緘する。 <Correction step S5>
The straightening step S5 is a step in which the straightening portion 50 sandwiches and handles the tube film Fc into which the content X is charged from the front-rear direction.
When the tube film Fc is sufficiently filled with the content X, the straightening portion 50 presses the tube film Fc from the front-back direction by the pair of straightening plates 54. As a result, the content X filled in the bottom of the tube film Fc is pushed up. The straightening plate 54 straightens the tube film Fc (film packaging bag 100) filled with the content X and expanded to a certain thickness.
When the straightening plate 54 corrects the shape of the tube film Fc, the content X is pushed up above the shigoki roller 52, and the air contained in the content X moves above the shigoki roller 52. As a result, the content X containing no air is arranged (filled) on the lower side of the tube film Fc.
Then, the straightening portion 50 squeezes the tube film Fc from the front-back direction by a pair of shigoki rollers 52. The straightening section 50 brings the pair of shigoki rollers 52 into close contact with each other to sandwich the shigoki rollers 52, and divides the content X in the vertical direction.
As a result, the tube film Fc is sealed, and a bag body filled with only the content X (a film packaging bag 100 whose upper end is unsealed) appears directly under the shigoki roller 52.
When the pair of shigoki rollers 52 are in close contact with each other, the straightening plate 54 is separated from the tube film Fc. The pair of shigoki rollers 52 seal the tube film Fc until the side sealing step S6 is completed.
　矯正工程Ｓ５を経ることにより、フィルム包装袋１００に内容物Ｘがエアレス充填される。内容物Ｘをエアレス充填するのは、内容物入りフィルム包装袋１００の製造後に行われる内容物Ｘの加熱殺菌処理の実効性（殺菌効率）を高めるためである。加熱殺菌処理時に蒸気口１２５が開口することを回避するためである。 By going through the straightening step S5, the content X is airlessly filled in the film packaging bag 100. The reason why the content X is airlessly filled is to enhance the effectiveness (sterilization efficiency) of the heat sterilization treatment of the content X performed after the production of the film packaging bag 100 containing the content. This is to prevent the steam port 125 from opening during the heat sterilization treatment.
〈サイドシール工程Ｓ６〉
　サイドシール工程Ｓ６は、サイドシール部６０がチューブフィルムＦｃ（上端が未封止のフィルム包装袋１００）にサイドシール１１０を形成する工程である。
　サイドシール部６０は、ヒーターバー６２により、チューブフィルムＦｃを左右方向にわたって熱溶着してサイドシール１１０を形成する。
　サイドシール１１０が形成されると、チューブフィルムＦｃが密閉されて、その最下端がフィルム包装袋１００になる。フィルム包装袋１００は、チューブフィルムＦｃの下端に吊り下げられる。 <Side sealing process S6>
The side seal step S6 is a step in which the side seal portion 60 forms the side seal 110 on the tube film Fc (the film packaging bag 100 whose upper end is unsealed).
The side seal portion 60 heat-welds the tube film Fc in the left-right direction by the heater bar 62 to form the side seal 110.
When the side seal 110 is formed, the tube film Fc is sealed, and the lowermost end thereof becomes the film packaging bag 100. The film packaging bag 100 is suspended from the lower end of the tube film Fc.
〈袋体切離工程Ｓ７〉
　袋体切離工程Ｓ７は、カッター部７０がチューブフィルムＦｃから内容物入りフィルム包装袋１００を切り落とす工程である。
　カッター部７０は、ヒーターバー６２に内蔵されたカッター７２により、フィルム包装袋１００の上方側のサイドシール１１０を左右方向にわたって切断する。カッター７２でサイドシール１１０を上下方向に二分割するように切断する。これにより、チューブフィルムＦｃの下端から内容物入りフィルム包装袋１００が切り離される。 <Bag body cutting step S7>
The bag body cutting step S7 is a step in which the cutter portion 70 cuts off the film packaging bag 100 containing the contents from the tube film Fc.
The cutter portion 70 cuts the side seal 110 on the upper side of the film packaging bag 100 in the left-right direction by the cutter 72 built in the heater bar 62. The side seal 110 is cut by the cutter 72 so as to be divided into two in the vertical direction. As a result, the film packaging bag 100 containing the contents is separated from the lower end of the tube film Fc.
　以上により、内容物入りフィルム包装袋１００を製造する工程が完了する。
　縦型製袋充填包装機１は、内容物入りフィルム包装袋１００を製造する工程を繰り返す。これにより、縦型製袋充填包装機１は、複数の内容物入りフィルム包装袋１００を連続して製造する。 This completes the process of manufacturing the film packaging bag 100 containing the contents.
The vertical bag-making filling and packaging machine 1 repeats the process of manufacturing the film packaging bag 100 containing the contents. As a result, the vertical bag-making filling and packaging machine 1 continuously manufactures a plurality of film packaging bags 100 containing contents.
　この内容物入り包装袋の製造方法は、フィルム包装袋１００を製袋し、内容物Ｘをフィルム包装袋１００に充填する。フィルム包装袋１００がピロー袋であるため、例えば内容物Ｘに直径３０ｍｍ程度の固形物が含まれる場合であっても、フィルム包装袋１００に内容物Ｘを円滑かつ効率的に充填することができる。
　特に、この内容物入り包装袋の製造方法によれば、背貼りシール１２０が長手方向の中央Ｃと第一端１０３の間に配置された内容物入りフィルム包装袋１００を連続して製造することができる。 In this method of manufacturing a packaging bag containing contents, a film packaging bag 100 is made and the contents X are filled in the film packaging bag 100. Since the film packaging bag 100 is a pillow bag, for example, even when the content X contains a solid substance having a diameter of about 30 mm, the film packaging bag 100 can be smoothly and efficiently filled with the content X. ..
In particular, according to this method for manufacturing a package containing contents, it is possible to continuously manufacture a film packaging bag 100 containing contents in which the backing seal 120 is arranged between the center C in the longitudinal direction and the first end 103. ..
〔第二実施形態：フィルム包装袋２００〕
　図９は、第二実施形態に係る内容物入りフィルム包装袋２００を示す図であって、（ａ）立てた姿勢の斜視図、（ｂ）開封後の状態の斜視図である。説明の都合上、図９は、内容物Ｘの充填量が僅かな場合を示している。
　フィルム包装袋１００と同一の部位等には、同一の符号を付してその説明を省略する。 [Second embodiment: film packaging bag 200]
9A and 9B are views showing the film packaging bag 200 containing the contents according to the second embodiment, which are (a) a perspective view of an upright posture and (b) a perspective view of a state after opening. For convenience of explanation, FIG. 9 shows a case where the filling amount of the content X is small.
The same parts and the like as the film packaging bag 100 are designated by the same reference numerals, and the description thereof will be omitted.
　フィルム包装袋２００は、第二端１０４にフィルムＦが二重（Ｍ字形）に折り込まれた底ガセット１５０を備える。底ガセット１５０は、前底フラップ１５１と後底フラップ１５２からなる。前底フラップ１５１と後底フラップ１５２は、長手方向の長さＬ１，Ｌ２が同一（例えば２０ｍｍから３０ｍｍ）である。
　前底フラップ１５１と後底フラップ１５２の短手方向（横方向）の両端同士は互いに溶着されていない。このため、前底フラップ１５１と後底フラップ１５２をそれぞれ前後方向に折り曲げることにより、フィルム包装袋２００を側方から見ると、逆Ｔ字形にすることができる。これにより、底ガセット１５０を底（下方）にして、フィルム包装袋２００を安定して自立させることができる。
　したがって、フィルム包装袋２００は、自立させた状態で陳列できる。さらに、フィルム包装袋２００は、自立された状態で電子レンジや湯煎により内容物Ｘを加熱調理できる。 The film packaging bag 200 includes a bottom gusset 150 in which the film F is double-folded (M-shaped) at the second end 104. The bottom gusset 150 comprises a front bottom flap 151 and a rear bottom flap 152. The front bottom flap 151 and the back bottom flap 152 have the same lengths L1 and L2 in the longitudinal direction (for example, 20 mm to 30 mm).
Both ends of the front bottom flap 151 and the rear bottom flap 152 in the lateral direction (lateral direction) are not welded to each other. Therefore, by bending the front bottom flap 151 and the rear bottom flap 152 in the front-rear direction, the film packaging bag 200 can be formed into an inverted T shape when viewed from the side. As a result, the bottom gusset 150 can be set to the bottom (downward), and the film packaging bag 200 can be stably made to stand on its own.
Therefore, the film packaging bag 200 can be displayed in an independent state. Further, the film packaging bag 200 can heat and cook the contents X in a microwave oven or a water bath in a self-supporting state.
　フィルム包装袋２００を自立させたときに、背貼りシール１２０の位置は、内容物Ｘ（液面）よりも第一端側になるように配置される。これにより、自立させた状態で内容物Ｘを加熱調理しても、蒸気口１２５が内容物Ｘよりも上方（第一端１０３側）に位置するので、蒸気口１２５から内容物Ｘが吹きこぼれない。
　内容物Ｘに液体が多い場合は、フィルム包装袋２００を自立させた状態で加熱するのが好ましい。これにより、内容物Ｘの液体が開口Ｐ（蒸気口１２５）から吹きこぼれにくい。フィルム包装袋２００を自立させると、内容物Ｘの液体が対流しやすくなる。内容物Ｘが水と米のときは、水（湯）と米が対流して、米が斑なく加熱される。これにより、良好な炊飯が可能になる。 When the film packaging bag 200 is made to stand on its own, the position of the backing seal 120 is arranged so as to be on the first end side of the content X (liquid level). As a result, even if the content X is cooked in a self-supporting state, the steam port 125 is located above the content X (on the side of the first end 103), so that the content X does not spill out from the steam port 125. ..
When the content X contains a large amount of liquid, it is preferable to heat the film packaging bag 200 in a self-supporting state. As a result, the liquid of the content X is less likely to spill out from the opening P (steam port 125). When the film packaging bag 200 is made to stand on its own, the liquid of the content X is easily convected. When the content X is water and rice, the water (hot water) and rice convection, and the rice is heated without spots. This enables good rice cooking.
　フィルム包装袋２００は、第一端１０３側を切り落とすと、そのまま深さのある容器として使用することができる。フィルム包装袋２００から内容物Ｘを取り出して皿に盛り付ける必要がない。第一端１０３側を切り落としたフィルム包装袋２００を食卓に自立させて、食器として使用する。これにより、食後の食器洗いの負担を大幅に軽減することができる。
　背貼りシール１２０が上下方向（長手方向）の中央よりも上方側に配置されているので、フィルム包装袋２００の開封口Ｐが高い位置に形成される。したがって、フィルム包装袋２００は、深さがあって容量の大きな食器（ボウルや鉢、椀）として使用できる。 The film packaging bag 200 can be used as a deep container as it is by cutting off the 103 side of the first end. It is not necessary to take out the content X from the film packaging bag 200 and serve it on a plate. The film packaging bag 200 with the first end 103 side cut off is allowed to stand on the table and used as tableware. As a result, the burden of washing dishes after meals can be significantly reduced.
Since the backing seal 120 is arranged above the center in the vertical direction (longitudinal direction), the opening P of the film packaging bag 200 is formed at a high position. Therefore, the film packaging bag 200 can be used as deep and large-capacity tableware (bowl, bowl, bowl).
　フィルム包装袋２００では、消費者のフィルムＦを切り裂く力が背貼りシール１２０を介して開封口Ｐの裂け目の先端に伝わる。このため、開封口Ｐが背貼りシール１２０に沿って真っすぐに形成される。したがって、フィルム包装袋２００は、開封後の見栄えがよく、食器として好適に使用できる。
　フィルム包装袋２００は、開封口Ｐを形成する際に背貼りシール１２０も切り落とされる。このため、フィルム包装袋２００は、食器として使用するときに、開封口Ｐを大きく開いた状態を維持できる。したがって、スプーンやフォーク、箸等のカトラリー類を用いて、フィルム包装袋２００から内容物Ｘを取り出し易くなる。 In the film packaging bag 200, the force of tearing the film F of the consumer is transmitted to the tip of the crevice of the opening P via the backing seal 120. Therefore, the opening P is formed straight along the backing seal 120. Therefore, the film packaging bag 200 has a good appearance after opening and can be suitably used as tableware.
In the film packaging bag 200, the backing seal 120 is also cut off when the opening P is formed. Therefore, when the film packaging bag 200 is used as tableware, the opening port P can be kept wide open. Therefore, it becomes easy to take out the content X from the film packaging bag 200 by using cutlery such as a spoon, a fork, and chopsticks.
〔第三実施形態：フィルム包装袋３００〕
　図１０は、第三実施形態に係る内容物入りフィルム包装袋３００を示す図であって、（ａ）立てた姿勢の斜視図、（ｂ）加熱調理中の状態の模式側面である。説明の都合上、図１０（ａ）は、内容物Ｘの充填量が僅かな場合を示している。
　フィルム包装袋１００，２００と同一の部位等には、同一の符号を付してその説明を省略する。 [Third Embodiment: film packaging bag 300]
FIG. 10 is a diagram showing a film packaging bag 300 containing contents according to a third embodiment, in which (a) a perspective view of an upright posture and (b) a schematic side view of a state during cooking. For convenience of explanation, FIG. 10A shows a case where the filling amount of the content X is small.
The same parts as those of the film packaging bags 100 and 200 are designated by the same reference numerals and the description thereof will be omitted.
　フィルム包装袋３００は、第二端１０４に底ガセット１５０を備える。底ガセット１５０は、長手方向において、前底フラップ１５１の長さＬ１が大きく（長い）、後底フラップ１５２の長さＬ２が小さい（短い）。例えば前底フラップ１５１の長さＬ１は３０ｍｍ、後底フラップ１５２の長さＬ２は２０ｍｍである。
　フィルム包装袋３００は、平置きして内容物Ｘを加熱調理すると、内圧上昇により膨れ上がる。このとき、前底フラップ１５１は膨らみが大きいが、後底フラップ１５２は膨らみが小さい。このため、フィルム包装袋３００が長手方向前方側に傾いて第一端１０３側が低くなることを回避できる。したがって、背貼りシール１２０の蒸気口１２５が開口したときに、蒸気口１２５から内容物Ｘ（特に液体）が吹きこぼれづらい。 The film packaging bag 300 includes a bottom gusset 150 at the second end 104. In the bottom gusset 150, the length L1 of the front bottom flap 151 is large (long) and the length L2 of the rear bottom flap 152 is small (short) in the longitudinal direction. For example, the length L1 of the front bottom flap 151 is 30 mm, and the length L2 of the rear bottom flap 152 is 20 mm.
When the film packaging bag 300 is placed flat and the contents X are cooked by heating, the film packaging bag 300 swells due to an increase in internal pressure. At this time, the front bottom flap 151 has a large bulge, but the rear bottom flap 152 has a small bulge. Therefore, it is possible to prevent the film packaging bag 300 from tilting toward the front side in the longitudinal direction and lowering the first end 103 side. Therefore, when the steam port 125 of the backing seal 120 is opened, it is difficult for the contents X (particularly liquid) to spill out from the steam port 125.

FIG. 11 is a diagram showing a film packaging bag 400 containing contents according to a fourth embodiment, in which (a) a perspective view of an upright posture and (b) a schematic side view of a state during cooking. For convenience of explanation, FIG. 11A shows a case where the filling amount of the content X is small.
The same parts as those of the film packaging bags 100 to 300 are designated by the same reference numerals and the description thereof will be omitted.
　フィルム包装袋４００は、底ガセット１５０に加えて、第一端１０３に天ガセット１６０を備える。天ガセット１６０は、前天フラップ１６１と後天フラップ１６２からなる。
　前天フラップ１６１と後天フラップ１６２は、長手方向の長さＬ３，Ｌ４が同一（例えば２０ｍｍから３０ｍｍ）である。前天フラップ１６１と後天フラップ１６２の短手方向（横方向）の両端同士は互いに溶着されていない。このため、前底フラップ１５１と後底フラップ１５２をそれぞれ前後方向に折り曲げることにより、フィルム包装袋４００の上部を側方から見ると、Ｔ字形にすることができる。
　さらに、後底フラップ１５２の長手方向の長さＬ２と後天フラップ１６２の長手方向の長さＬ４は、同一である。 The film packaging bag 400 includes a top gusset 160 at the first end 103 in addition to the bottom gusset 150. The heavenly gusset 160 is composed of an anterior flap 161 and an acquired flap 162.
The anterior flap 161 and the acquired flap 162 have the same lengths L3 and L4 in the longitudinal direction (for example, 20 mm to 30 mm). Both ends of the anterior flap 161 and the acquired flap 162 in the lateral direction (lateral direction) are not welded to each other. Therefore, by bending the front bottom flap 151 and the rear bottom flap 152 in the front-rear direction, the upper portion of the film packaging bag 400 can be formed into a T-shape when viewed from the side.
Further, the longitudinal length L2 of the rear bottom flap 152 and the longitudinal length L4 of the acquired flap 162 are the same.
　フィルム包装袋４００は、平置きして内容物Ｘを加熱調理すると、内圧上昇により膨れ上がる。このとき、底ガセット１５０の後底フラップ１５２と天ガセット１６０の後天フラップ１６２の膨らみはほぼ同一になる。このため、フィルム包装袋４００が長手方向前方側に傾きいて第一端１０３側が低くなることを回避できる。したがって、背貼りシール１２０の蒸気口１２５が開口したときに、蒸気口１２５から内容物Ｘ（特に液体）が吹きこぼれづらい。
　底ガセット１５０の後底フラップ１５２と天ガセット１６０の後天フラップ１６２の長さが同一であればよく、前底フラップ１５１と前天フラップ１６１の長さは任意である。 When the film packaging bag 400 is placed flat and the contents X are cooked by heating, the film packaging bag 400 swells due to an increase in internal pressure. At this time, the bulges of the rear bottom flap 152 of the bottom gusset 150 and the posterior flap 162 of the heaven gusset 160 are almost the same. Therefore, it is possible to prevent the film packaging bag 400 from tilting toward the front side in the longitudinal direction and lowering the first end 103 side. Therefore, when the steam port 125 of the backing seal 120 is opened, it is difficult for the contents X (particularly liquid) to spill out from the steam port 125.
The lengths of the rear bottom flap 152 of the bottom gusset 150 and the posterior flap 162 of the heaven gusset 160 may be the same, and the lengths of the front bottom flap 151 and the front heaven flap 161 are arbitrary.

　図１２は、第五実施形態に係る内容物入りフィルム包装袋５００を示す図であって、（ａ）立てた姿勢の斜視図、（ｂ）加熱調理中の状態の模式側面である。説明の都合上、図１２（ａ）は、内容物Ｘの充填量が僅かな場合を示している。
　フィルム包装袋１００～４００と同一の部位等には、同一の符号を付してその説明を省略する。 [Fifth Embodiment: Film packaging bag 500]
FIG. 12 is a diagram showing a film packaging bag 500 containing contents according to a fifth embodiment, in which (a) a perspective view of an upright posture and (b) a schematic side view of a state during cooking. For convenience of explanation, FIG. 12A shows a case where the filling amount of the content X is small.
The same parts as those of the film packaging bags 100 to 400 are designated by the same reference numerals and the description thereof will be omitted.
　フィルム包装袋５００は、底ガセット１５０と天ガセット１６０を備える。底ガセット１５０は、長手方向において、前底フラップ１５１の長さＬ１が大きく（長く）、後底フラップ１５２の長さＬ２が小さい（短い）。
　一方、天ガセット１６０は、長手方向において、前天フラップ１６１の長さＬ３が小さく（短く）、後天フラップ１６２の長さＬ４が大きい（長い）。例えば前底フラップ１５１と後天フラップ１６２は３０ｍｍ、後底フラップ１５２と前天フラップ１６１は２０ｍｍである。 The film packaging bag 500 includes a bottom gusset 150 and a top gusset 160. In the bottom gusset 150, the length L1 of the front bottom flap 151 is large (long) and the length L2 of the rear bottom flap 152 is small (short) in the longitudinal direction.
On the other hand, in the heaven gusset 160, the length L3 of the anterior flap 161 is small (short) and the length L4 of the posterior flap 162 is large (long) in the longitudinal direction. For example, the front bottom flap 151 and the acquired flap 162 are 30 mm, and the rear bottom flap 152 and the acquired flap 161 are 20 mm.
　フィルム包装袋５００は、平置きして内容物Ｘを加熱調理すると、内圧上昇により膨れ上がる。
このとき、底ガセット１５０の後底フラップ１５２の膨らみに比べて、天ガセット１６０の後天フラップ１６２の膨らみは小さくなる。このため、フィルム包装袋４００が長手方向後方側に傾いて第一端１０３側が高くなる。したがって、背貼りシール１２０の蒸気口１２５が開口したときに、蒸気口１２５から内容物Ｘ（特に液体）が吹きこぼれづらい。
　底ガセット１５０の後底フラップ１５２の長さが天ガセット１６０の後天フラップ１６２の長さに比べて小さければよく、前底フラップ１５１と前天フラップ１６１の長さは任意である。 When the film packaging bag 500 is placed flat and the contents X are cooked by heating, the film packaging bag 500 swells due to an increase in internal pressure.
At this time, the bulge of the rear flap 162 of the heaven gusset 160 is smaller than the bulge of the rear bottom flap 152 of the bottom gusset 150. Therefore, the film packaging bag 400 is tilted to the rear side in the longitudinal direction, and the first end 103 side is raised. Therefore, when the steam port 125 of the backing seal 120 is opened, it is difficult for the contents X (particularly liquid) to spill out from the steam port 125.
The length of the rear bottom flap 152 of the bottom gusset 150 may be smaller than the length of the posterior flap 162 of the ceiling gusset 160, and the lengths of the front bottom flap 151 and the front ceiling flap 161 are arbitrary.
　図１３は、天ガセット形成部８１および底ガセット形成部８２を示す模式平面図である。
　フィルム包装袋２００～５００を製造するために、縦型製袋充填包装機１は、一対の案内針１４に代えて、天ガセット形成部８１、底ガセット形成部８２を備える。すなわち、内容物入りフィルム包装袋１００の製造方法において、製袋ガイド工程と背貼りシール工程の直後に、天ガセット形成工程や底ガセット形成工程を行う。
