　外装フィルム９１は、底辺９４、第一側辺９５、第二側辺９６および天辺９７を有している。底辺９４は、パウチ容器Ｘが店頭等において陳列される際に、鉛直方向下方に位置して陳列棚などに接することが意図された辺である。天辺９７は、底辺９４とは反対側に位置する辺である。第一側辺９５および第二側辺９６は、底辺９４および天辺９７をそれぞれ繋いでいる。第一側辺９５は、底辺９４に対して垂直である。第二側辺９６は、垂直部９６１および傾斜部９６２を有している。垂直部９６１は、底辺９４側に位置しており、底辺９４に対して垂直である。傾斜部９６２は、天辺９７側に位置しており、底辺９４に対して傾いている。底側フィルム９２は、底辺９４に平行に折り畳まれた状態で、一対の外装フィルム９１に挟まれている。底側フィルム９２は、底辺９４と一致する一対の底辺を有している。 The exterior film 91 has a base 94, a first side 95, a second side 96, and a top 97. When the pouch container X is displayed at a storefront or the like, the bottom side 94 is a side that is intended to be in contact with a display shelf or the like by being positioned vertically downward. The top side 97 is a side located on the side opposite to the bottom side 94. The first side 95 and the second side 96 connect the bottom 94 and the top 97, respectively. The first side 95 is perpendicular to the bottom 94. The second side 96 has a vertical part 961 and an inclined part 962. The vertical portion 961 is located on the base 94 side and is perpendicular to the base 94. The inclined portion 962 is located on the top side 97 side and is inclined with respect to the bottom side 94. The bottom film 92 is sandwiched between a pair of exterior films 91 in a state of being folded in parallel with the bottom 94. The bottom film 92 has a pair of bottom sides that coincide with the bottom side 94.
　底側シール部９４ａは、外装フィルム９１と底側フィルム９２とが、底辺９４に沿って接合された部分である。第一側方シール部９５ａは、一対の外装フィルム９１同士が、第一側辺９５に沿って接合された部分である。第二側方シール部９６１ａは、一対の外装フィルム９１同士が、垂直部９６１に沿って接合された部分である。一対の外装フィルム９１の傾斜部９６２同士の間にはスパウト９３の挿入部９３ａが挿入されている。スパウトシール部９６２ａは、スパウト９３の挿入部９３ａを挟んで一対の外装フィルム９１同士がスパウトシール部９６２ａに沿って部分である。天側シール部９７ａは、一対の外装フィルム９１同士が天辺９７に沿って接合された部分である。パウチ容器Ｘの製造工程においては、たとえば天側シール部９７ａ以外の前記シール部を形成した後に、内容物を充填し、その後に天側シール部９７ａが形成される。 The bottom seal portion 94 a is a portion where the exterior film 91 and the bottom film 92 are joined along the bottom side 94. The first side seal portion 95 a is a portion where a pair of exterior films 91 are joined along the first side 95. The second side seal portion 961 a is a portion where a pair of exterior films 91 are joined along the vertical portion 961. An insertion portion 93 a of a spout 93 is inserted between the inclined portions 962 of the pair of exterior films 91. The spout seal portion 962a is a portion along the spout seal portion 962a between the pair of exterior films 91 with the insertion portion 93a of the spout 93 interposed therebetween. The top seal portion 97 a is a portion where a pair of exterior films 91 are joined along the top side 97. In the manufacturing process of the pouch container X, for example, after forming the seal portion other than the top seal portion 97a, the contents are filled, and then the top seal portion 97a is formed.
　スパウト９３は、前記内容物を注出するためのものであり、全体として前記内容物を通過させる筒状の部分を有している。このため、スパウトシール部９６２ａのうちスパウト９３の挿入部９３ａが挟まれた部分は、一対の外装フィルム９１が挿入部９３ａを迂回するようにして挿入部９３ａに接合されている。一対の外装フィルム９１が迂回する長さは、スパウト９３の大きさに依存する。たとえば、パウチ容器Ｘの内容物として、粉体などが選択された場合、スパウト９３は、液体の内容物を注出する場合と比べて、内径がより大きい大型のものとなる。このようなスパウト９３を挟んだ状態でスパウトシール部９６２ａを形成すると、一対の外装フィルム９１が迂回する長さがより長くなる。この結果、天辺９７の図中左端が斜め下方に引き寄せられることとなり、天辺９７が底辺９４（図中水平線）に対して角度θだけ傾いてしまう。この角度θが過大であると、パウチ容器Ｘを陳列した際に、天辺９７が水平線に対して傾いてしまい、パウチ容器Ｘの外観が損なわれる。また、パウチ容器Ｘの製造工程において内容物を充填する際や天側シール部９７ａを形成する際には、天辺９７が位置決めの基準として用いられやすい。この天辺９７が意図せず傾いていると、内容物の充填や天側シール部９７ａの形成を適切に行えないことが懸念される。 The spout 93 is for pouring out the contents, and has a cylindrical portion that allows the contents to pass through as a whole. For this reason, a portion of the spout seal portion 962a where the insertion portion 93a of the spout 93 is sandwiched is joined to the insertion portion 93a so that the pair of exterior films 91 bypass the insertion portion 93a. The length that the pair of exterior films 91 detour depends on the size of the spout 93. For example, when powder or the like is selected as the contents of the pouch container X, the spout 93 becomes a large-sized one having an inner diameter larger than that when the liquid contents are poured out. When the spout seal portion 962a is formed with the spout 93 interposed therebetween, the length of the detouring of the pair of exterior films 91 becomes longer. As a result, the left end of the top side 97 in the figure is drawn obliquely downward, and the top side 97 is inclined by an angle θ with respect to the base 94 (horizontal line in the figure). If the angle θ is excessively large, the top 97 is inclined with respect to the horizontal line when the pouch container X is displayed, and the appearance of the pouch container X is impaired. In addition, when filling the contents in the manufacturing process of the pouch container X or when forming the top seal portion 97a, the top 97 is easily used as a positioning reference. If the top edge 97 is unintentionally inclined, there is a concern that the filling of the contents and the formation of the top seal part 97a cannot be performed appropriately.

　本発明は、上記した事情のもとで考え出されたものであって、美麗な外観のパウチ容器を適切に製造することが可能なパウチ容器用包材およびパウチ容器の製造方法を提供することをその課題とする。 The present invention has been conceived under the circumstances described above, and provides a packaging material for a pouch container and a method for manufacturing the pouch container that can appropriately manufacture a pouch container having a beautiful appearance. Is the subject.
　本発明の第一の側面によって提供されるパウチ容器用包材は、互いに反対側に位置する底辺および天辺と該底辺および該天辺を繋ぐ第一側辺および第二側辺とを各々が有する一対の外装フィルムを備え、前記第一側辺に沿って前記一対の外装フィルムが互いに接合された第一側方シール部と、前記第二側辺のうち前記底辺寄り部分に沿って前記一対の外装フィルムが互いに接合された第二側方シール部と、前記第二側辺のうち未接合である部分によって形成された側方開口部と、前記天辺によって形成された天側開口部と、を有しており、前記天辺は、前記第二側辺に向かうほど前記底辺からの距離が大となるように前記底辺に対して傾いていることを特徴としている。 The packaging material for a pouch container provided by the first aspect of the present invention includes a pair of bases and tops that are opposite to each other, and a first side and a second side that connect the bases and the tops. A first side seal portion in which the pair of exterior films are joined to each other along the first side, and the pair of exteriors along the bottom side portion of the second side A second side seal part in which the films are joined together, a side opening part formed by an unjoined part of the second side part, and a top side opening part formed by the top part. The top side is inclined with respect to the bottom side so that the distance from the bottom side becomes larger toward the second side side.
　本発明の好ましい実施の形態においては、前記第二側辺は、前記底辺側に位置するとともに前記底辺に対して垂直である垂直部と、前記天辺側に位置するとともに前記天辺に向かうほど前記第一側辺に近接するように傾いた傾斜部と、を有しており、前記第二側方シール部は、前記第二側辺の前記垂直部に沿って前記一対の外装フィルムが互いにシールされており、前記側方開口部は、前記第二側辺の前記傾斜部によって形成されている。 In a preferred embodiment of the present invention, the second side is located on the bottom side and is perpendicular to the bottom side, and the second side is located on the top side and closer to the top side. And the second side seal portion is configured such that the pair of exterior films are sealed to each other along the vertical portion of the second side edge. The side opening is formed by the inclined portion of the second side.
　本発明の好ましい実施の形態においては、前記底辺に平行に折り畳まれた状態で前記一対の外装フィルムの間に位置し、前記一対の外装フィルムの前記底辺に沿う一対の底辺を有する底側フィルムをさらに備え、前記一対の外装フィルムと前記底側フィルムとが各々の前記底辺に沿って接合された一対の底側シール部を具備する。 In a preferred embodiment of the present invention, a bottom film that is positioned between the pair of exterior films in a state of being folded in parallel with the bottom sides and has a pair of bottom sides along the bottom sides of the pair of exterior films, And a pair of bottom-side seal portions in which the pair of exterior films and the bottom-side film are joined along the bottom sides.
　本発明の第一の側面によって提供されるパウチ容器の製造方法は、本発明の第一の側面によって提供されるパウチ容器用包材を用意する工程と、前記側方開口部にスパウトを挿入した状態で前記側方開口部を接合することにより、スパウトシール部を形成する工程と、前記天側開口部から内容物を充填する工程と、前記天側開口部を接合することにより、天側シール部を形成する工程と、を備えることを特徴としている。 The method for manufacturing a pouch container provided by the first aspect of the present invention includes a step of preparing a packaging material for a pouch container provided by the first aspect of the present invention, and inserting a spout into the side opening. A step of forming a spout seal portion by joining the side openings in a state, a step of filling the contents from the top opening, and a joining of the top opening, And a step of forming a portion.
　本発明の好ましい実施の形態においては、前記パウチ用包材を用意する工程においては、各々が２つの前記パウチ用包材の前記外装フィルムを形成する幅を有する一対の外装フィルム材料を重ね合わせるとともに、前記各外装フィルム材料の幅方向において、２つの前記外装フィルムを互いの前記天辺が平行に対向するように設定する。 In a preferred embodiment of the present invention, in the step of preparing the pouch packaging material, a pair of exterior film materials each having a width that forms the exterior film of the two pouch packaging materials are overlapped. In the width direction of each of the exterior film materials, the two exterior films are set so that the top sides thereof face each other in parallel.
　前記パウチ容器用包材の前記側方開口部にスパウトを挿入し、このスパウトを挟んで前記一対の外装フィルムを接合すると、前記第二側辺の平面視における見かけの長さが短くなる。しかし、本発明によれば、前記天辺が前記第二側辺に向かうほど前記底辺との距離が大となるように前記底辺に対して傾いている。このため、前記スパウトを挟んで前記一対の外装フィルムを接合した後に、前記天辺を前記底辺に対して平行か、より平行に近い状態とすることができる。この結果、前記パウチ容器用包材を用いて製造したパウチ容器において、前記底辺が前記天辺に対して不当に傾いてしまうことを防止することができる。したがって、前記パウチ容器の外観をより美麗に保つことができる。また、内容物の充填工程や、前記一対の外装フィルムを前記天側開口部に沿って接合する工程においては、前記天辺を充填作業や形成作業の位置決めに用いることが一般的である。この天辺が前記底辺に対して不当に傾いておらず、前記底辺に対して平行か、より平行な状態とされていることにより、前記充填工程や前記シール工程を適切に行うことができる。 When a spout is inserted into the side opening of the packaging material for the pouch container and the pair of exterior films are joined with the spout sandwiched therebetween, the apparent length in plan view of the second side is shortened. However, according to this invention, it inclines with respect to the said base so that the distance with the said base may become so large that the said top part goes to the said 2nd side. For this reason, after joining a pair of exterior films on both sides of the spout, the top can be made into the state where it is parallel or nearer parallel to the bottom. As a result, in the pouch container manufactured using the packaging material for the pouch container, it is possible to prevent the bottom side from being unduly inclined with respect to the top side. Therefore, the appearance of the pouch container can be kept more beautiful. In addition, in the content filling step and the step of joining the pair of exterior films along the top opening, it is common to use the top side for filling operation or positioning operation. Since the top side is not unreasonably inclined with respect to the bottom side and is parallel or more parallel to the bottom side, the filling step and the sealing step can be appropriately performed.
　本発明のその他の特徴および利点は、添付図面を参照して以下に行う詳細な説明によって、より明らかとなろう。 Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the accompanying drawings.

　図２および図３は、パウチ容器用包材Ａ１を用意する工程の一例を示している。この工程においては、一対の外装フィルム材料１Ａおよび一対の底側フィルム材料２Ａを用いる。一対の外装フィルム材料１Ａおよび一対の底側フィルム材料２Ａは、複数のパウチ容器用包材Ａ１を順次製造するためのものである。すなわち、一対の外装フィルム材料１Ａから複数対の外装フィルム１が形成され、底側フィルム材料２Ａから複数の底側フィルム２が形成される。一対の外装フィルム材料１Ａは互いに重ね合わされており、各々が図２における図中左右方向を長手方向とし、図中上下方向を幅方向とする帯状である。一対の底側フィルム材料２Ａは、一対の外装フィルム材料１Ａの間に位置しており、図中上下方向に離間して配置されている。図３に示すように、各底側フィルム材料２Ａは、折り返し部２２において折り畳まれている。また、同図に示された例においては、底側フィルム材料２Ａの一対の端縁が外装フィルム材料１Ａの端縁と一致している。また、各底側フィルム材料２Ａには、複数の切り欠き部２５が予め形成されている。 2 and 3 show an example of a process for preparing the packaging material A1 for a pouch container. In this step, a pair of exterior film materials 1A and a pair of bottom film materials 2A are used. The pair of exterior film materials 1A and the pair of bottom film materials 2A are for sequentially manufacturing a plurality of pouch container packaging materials A1. That is, a plurality of pairs of exterior films 1 are formed from a pair of exterior film materials 1A, and a plurality of bottom films 2 are formed from the bottom film material 2A. A pair of exterior film materials 1A are overlapped with each other, and each has a strip shape in which the left-right direction in the drawing in FIG. 2 is the longitudinal direction and the up-down direction in the drawing is the width direction. A pair of bottom film material 2A is located between a pair of exterior film materials 1A, and is spaced apart in the up-down direction in the figure. As shown in FIG. 3, each bottom film material 2 </ b> A is folded at the folded portion 22. Moreover, in the example shown by the figure, a pair of edge of 2 A of bottom film materials corresponds with the edge of exterior film material 1A. Each bottom film material 2A has a plurality of notches 25 formed in advance.
　図２に示すように、一対の外装フィルム材料１Ａおよび一対の底側フィルム材料２Ａからは、図中上下方向（外装フィルム材料１Ａの幅方向）に２列に並べられた複数のパウチ容器用包材Ａ１が形成される。複数のパウチ容器用包材Ａ１を形成するためのシール工程および切断工程に際しては、複数のパウチ容器用包材Ａ１が図示された配置で設定される。すなわち、外装フィルム材料１Ａの幅方向に、２つの外装フィルム１が設定される。これらの外装フィルム１は、一方の外装フィルム１を１８０°回転させると他方の外装フィルム１と一致する。また、２つの外装フィルム１の天辺１２同士が、互いに平行に対向している。 As shown in FIG. 2, from a pair of exterior film materials 1A and a pair of bottom film materials 2A, a plurality of pouch container packages arranged in two rows in the vertical direction (width direction of the exterior film material 1A) in the figure. Material A1 is formed. In the sealing step and the cutting step for forming the plurality of pouch container packaging materials A1, the plurality of pouch container packaging materials A1 are set in the illustrated arrangement. That is, two exterior films 1 are set in the width direction of the exterior film material 1A. These exterior films 1 coincide with the other exterior film 1 when one exterior film 1 is rotated by 180 °. Further, the top sides 12 of the two exterior films 1 face each other in parallel.
　図示された一対の外装フィルム材料１Ａおよび一対の底側フィルム２に対して、底側シール部１５、第一側方シール部１６および第二側方シール部１７１を形成するためのシール工程と、底辺１１、天辺１２、第一側辺１３および第二側辺１４を形成するための切断工程とを行う。これにより、図１に示したパウチ容器用包材Ａ１が得られる。なお、パウチ容器用包材Ａ１を得るための前記シール工程と前記切断工程の順序は特に限定されないが、前記シール工程を行った後に、前記切断工程を行う構成が合理的である。 A sealing step for forming the bottom side seal part 15, the first side seal part 16 and the second side seal part 171 with respect to the pair of exterior film materials 1A and the pair of bottom side films 2 shown in the figure, A cutting process for forming the base 11, the top 12, the first side 13 and the second side 14 is performed. Thereby, the packaging material A1 for pouch containers shown in FIG. 1 is obtained. The order of the sealing step and the cutting step for obtaining the packaging material A1 for the pouch container is not particularly limited, but the configuration in which the cutting step is performed after the sealing step is rational.
　次いで、図４に示すように、スパウト３をパウチ容器用包材Ａ１の側方開口部１７０に挿入する。スパウト３は、パウチ容器用包材Ａ１を用いたパウチ容器において内容物を注出するためのものである。スパウト３の材質は特に限定されないが、一般的には樹脂からなる。また、スパウト３の具体的構成は特に限定されないが、本実施形態においては、スパウト３が筒部３１、拡幅部３２およびキャップ３３を有する場合を例に説明する。筒部３１は、略円筒形状の部位であり、前記内容物を通過させるためのものである。拡幅部３２は、筒部３１の一部の外形が特定方向に広げられた部位である。本実施形態の拡幅部３２は、筒部３１の中心軸に対して直角な方向において両側に延出する羽状の部分が設けられている。キャップ３３は、ねじなどによって筒部３１に嵌合する部位である。 Next, as shown in FIG. 4, the spout 3 is inserted into the side opening 170 of the packaging material A1 for the pouch container. The spout 3 is for pouring the contents in the pouch container using the packaging material A1 for the pouch container. The material of the spout 3 is not particularly limited, but is generally made of resin. Moreover, although the specific structure of the spout 3 is not specifically limited, in this embodiment, the case where the spout 3 has the cylinder part 31, the wide part 32, and the cap 33 is demonstrated to an example. The cylinder part 31 is a substantially cylindrical part and is used for allowing the contents to pass therethrough. The widened portion 32 is a portion where a part of the outer shape of the cylindrical portion 31 is widened in a specific direction. The widened portion 32 of the present embodiment is provided with wing-like portions extending on both sides in a direction perpendicular to the central axis of the cylindrical portion 31. The cap 33 is a part that fits into the cylindrical part 31 with a screw or the like.
　ここで、上述したパウチ容器用包材Ａ１のマージンＭｇの設定例について述べる。本例においては、底辺１１と天辺１２との平均的な距離が１５０ｍｍ～２００ｍｍ程度である。また、スパウト３の拡幅部３２の平面視における幅寸法が３８ｍｍ程度であり、拡幅部３２のうち一方の外装フィルム１に接合される接合長さが４７ｍｍ程度である。すなわち、拡幅部３２を挟んで一対の外装フィルム１を接合すると、拡幅部３２の前記幅寸法と前記接合長さとの差だけ、傾斜部１４２の平面視長さが見かけ上短くなる。このため、本例においては、図１においてマージンＭｇの長さを拡幅部３２の前記幅寸法と前記接合長さとの差である９ｍｍに設定し、これに整合するように天辺１２を底辺１１に対して傾斜させる。このような設定が施されたことを前提に、パウチ容器用包材Ａ１を用いたパウチ容器の製造方法の説明を以下に継続する。 Here, an example of setting the margin Mg of the packaging material A1 for the pouch container described above will be described. In this example, the average distance between the base 11 and the top 12 is about 150 mm to 200 mm. Moreover, the width dimension in planar view of the wide part 32 of the spout 3 is about 38 mm, and the joining length joined to one exterior film 1 among the wide parts 32 is about 47 mm. That is, when the pair of exterior films 1 are joined with the widened portion 32 interposed therebetween, the length in plan view of the inclined portion 142 is apparently shortened by the difference between the width dimension of the widened portion 32 and the joining length. For this reason, in this example, the length of the margin Mg in FIG. 1 is set to 9 mm which is the difference between the width dimension of the widened portion 32 and the joint length, and the top side 12 is set to the bottom side 11 so as to match this. Tilt against. On the assumption that such a setting has been made, the description of the method for manufacturing a pouch container using the pouch container packaging material A1 will be continued below.
　側方開口部１７０にスパウト３の拡幅部３２を挿入した状態で、図５および図６に示すように、一対の外装フィルム１同士を、スパウト３の拡幅部３２を挟んで垂直部１４１に沿ってヒートシール等によって接合する。これにより、スパウトシール部１７２が形成される。図６に示すように、スパウトシール部１７２の両端寄り部分においては、一対の外装フィルム１同士が接合されている。一方、スパウトシール部１７２のうち拡幅部３２が挟まれた部分においては、外装フィルム１と拡幅部３２とが気密状態で接合されている。
スパウトシール部１７２を形成すると、一対の外装フィルム１がスパウト３の拡幅部３２を迂回する形状となる。このため、傾斜部１４２は、図５に示すように、拡幅部３２を迂回する分だけ平面視における長さが短くなる。ただし、パウチ容器用包材Ａ１においては、天辺１２の形状を設定する際に、上述したマージンＭｇが考慮されている。このため、スパウトシール部１７２を形成した後は、図示されたように、天辺１２が底辺１１に対して平行となるか、あるいは形成前よりも平行に近い状態となる。 In a state where the widened portion 32 of the spout 3 is inserted into the side opening 170, the pair of exterior films 1 are arranged along the vertical portion 141 with the widened portion 32 of the spout 3 interposed therebetween, as shown in FIGS. 5 and 6. Join by heat sealing. Thereby, the spout seal | sticker part 172 is formed. As shown in FIG. 6, a pair of exterior films 1 are joined to each other at the end portions of the spout seal portion 172. On the other hand, in the portion of the spout seal portion 172 where the widened portion 32 is sandwiched, the exterior film 1 and the widened portion 32 are joined in an airtight state.
When the spout seal portion 172 is formed, the pair of exterior films 1 have a shape that bypasses the widened portion 32 of the spout 3. For this reason, as shown in FIG. 5, the inclined portion 142 has a shorter length in plan view as much as it bypasses the widened portion 32. However, in the packaging material A1 for the pouch container, the margin Mg described above is taken into consideration when setting the shape of the top 12. For this reason, after forming the spout seal part 172, as shown in the figure, the top 12 is parallel to the base 11 or is more nearly parallel than before formation.
　次いで、図７に示すように、パウチ容器用包材Ａ１に内容物４を充填する。内容物４の充填は、たとえば天側開口部１８０からノズルＮｚを挿入し、このノズルＮｚから内容物４を吐出することによって行う。この充填工程においては、パウチ容器用包材Ａ１とノズルＮｚとを正確に位置決めすることが必要である。この位置決めは、天辺１２の傾きや天辺１２の両端の位置などを所定のセンサ等を用いて検出することによって適切に行うことができる。 Next, as shown in FIG. 7, the contents 4 are filled into the packaging material A1 for the pouch container. The filling of the contents 4 is performed, for example, by inserting the nozzle Nz from the top opening 180 and discharging the contents 4 from the nozzle Nz. In this filling step, it is necessary to accurately position the pouch container packaging material A1 and the nozzle Nz. This positioning can be appropriately performed by detecting the inclination of the top 12 or the positions of both ends of the top 12 using a predetermined sensor or the like.
　内容物４を充填した後は、一対の外装フィルム１を天辺１２に沿って接合する。これにより、図８に示すように天側シール部１８が形成され、パウチ容器Ｂ１が得られる。天側シール部１８を形成するためのシール工程においては、ヒートシールによって接合するための金型とパウチ容器用包材Ａ１とを正確に位置決めすることが必要である。この位置決めにおいても、天辺１２の傾きや天辺１２の両端の位置などを所定のセンサ等を用いて検出することを利用できる。パウチ容器Ｂ１は、たとえば粉体等の内容物４を収容しており、この内容物４を気密状態で比較的長期間保持可能である。また、パウチ容器Ｂ１から内容物４を注出する際には、スパウト３のキャップ３３を取り外すことにより、筒部３１から内容物４を抽出することができる。 After filling the contents 4, the pair of exterior films 1 are joined along the top 12. Thereby, as shown in FIG. 8, the top seal part 18 is formed, and the pouch container B1 is obtained. In the sealing step for forming the top seal portion 18, it is necessary to accurately position the mold for bonding by heat sealing and the packaging material A1 for the pouch container. Also in this positioning, it is possible to use detection of the inclination of the top 12 and the positions of both ends of the top 12 using a predetermined sensor or the like. The pouch container B1 contains a content 4 such as powder, and can hold the content 4 in an airtight state for a relatively long period of time. Further, when the content 4 is poured out from the pouch container B1, the content 4 can be extracted from the cylindrical portion 31 by removing the cap 33 of the spout 3.
　次に、パウチ容器用包材Ａ１およびパウチ容器用包材Ａ１を用いたパウチ容器の製造方法の作用について説明する。 Next, the operation of the pouch container packaging material A1 and the method of manufacturing the pouch container using the pouch container packaging material A1 will be described.
　上述した通り、図１に示すパウチ容器用包材Ａ１の側方開口部１７０に図４に示すようにスパウト３を挿入し、このスパウト３を挟んで一対の外装フィルム１を接合すると、図４と図５との比較から理解されるように、傾斜部１４２の平面視における見かけの長さが短くなる。しかし、本実施形態によれば、図１および図４に示すように、天辺１２が第二側辺１４に向かうほど底辺１１との距離が大となるように底辺１１に対して傾いている。
このため、スパウトシール部１７２を形成した後に、天辺１２を底辺１１に対して平行か、より平行に近い状態とすることができる。この結果、パウチ容器用包材Ａ１を用いて製造した図８に示すパウチ容器Ｂ１において、底辺１１が天辺１２に対して不当に傾いてしまうことを防止することができる。したがって、パウチ容器Ｂ１の外観をより美麗に保つことができる。また、図７に示す内容物４の充填工程や、図８に示すパウチ容器Ｂ１の天側シール部１８を形成する工程においては、天辺１２を充填作業や形成作業の位置決めに用いることが一般的である。この天辺１２が底辺１１に対して不当に傾いておらず、底辺１１に対して平行か、より平行な状態とされていることにより、前記充填工程や前記シール工程を適切に行うことができる。 As described above, when the spout 3 is inserted into the side opening 170 of the pouch container packaging material A1 shown in FIG. 1 as shown in FIG. 4 and the pair of exterior films 1 are joined with the spout 3 sandwiched therebetween, FIG. As can be understood from the comparison between FIG. 5 and FIG. 5, the apparent length of the inclined portion 142 in plan view is shortened. However, according to the present embodiment, as shown in FIGS. 1 and 4, the top side 12 is inclined with respect to the bottom side 11 so that the distance from the bottom side 11 becomes larger as it goes to the second side side 14.
For this reason, after forming the spout seal | sticker part 172, the top 12 can be made into the state parallel to the base 11 or a near parallel state. As a result, in the pouch container B1 shown in FIG. 8 manufactured using the packaging material A1 for the pouch container, the bottom 11 can be prevented from being unduly inclined with respect to the top 12. Therefore, the appearance of the pouch container B1 can be kept more beautiful. In addition, in the filling process of the contents 4 shown in FIG. 7 and the process of forming the top side seal portion 18 of the pouch container B1 shown in FIG. 8, the top 12 is generally used for positioning of filling work and forming work. It is. Since the top 12 is not unreasonably inclined with respect to the bottom 11 and is parallel or more parallel to the bottom 11, the filling step and the sealing step can be appropriately performed.
　特に、内容物４が粉体である場合に内容物４をスムーズに注出するには、スパウト３の筒部３１の内径をより大きくする必要がある。パウチ容器用包材Ａ１の外形寸法、とくに傾斜部１４２の長さに対してスパウト３が大きいほど、スパウトシール部１７２を形成することによる傾斜部１４２の見かけの短縮が顕著となる。本実施形態によれば、パウチ容器用包材Ａ１の各部の寸法とスパウト３の寸法とから、上述したマージンＭｇを合理的かつ正確に設定することが可能であり、パウチ容器Ｂ１において天辺１２を底辺１１に対して平行か、より平行な状態に保つことができる。 Especially, when the contents 4 are powder, in order to smoothly pour the contents 4, it is necessary to increase the inner diameter of the cylindrical portion 31 of the spout 3. As the spout 3 is larger than the outer dimensions of the packaging material A1 for the pouch container, particularly the length of the inclined portion 142, the apparent shortening of the inclined portion 142 due to the formation of the spout seal portion 172 becomes more remarkable. According to the present embodiment, it is possible to set the margin Mg described above reasonably and accurately from the dimensions of the respective parts of the packaging material A1 for the pouch container and the dimensions of the spout 3, and the top 12 in the pouch container B1. It can be kept parallel or more parallel to the base 11.
　図２に示すように、パウチ容器用包材Ａ１を用意する工程においては、外装フィルム材料１Ａの幅方向において２つの外装フィルム１を、互いの天辺１２が平行に対向するように設定する。これにより、天辺１２が底辺１１に対して傾いているため、外装フィルム材料１Ａの幅方向端縁に対して天辺１２が傾いているにも関わらず、外装フィルム材料１Ａの幅方向において対向しあう２つの外装フィルム１同士の距離を、底辺１１が天辺１２と平行である場合と同程度に近づけることができる。これにより、外装フィルム材料１Ａに外装フィルム１とならなり無駄な部分が生じることを回避することができる。 As shown in FIG. 2, in the step of preparing the packaging material A1 for the pouch container, the two exterior films 1 are set in the width direction of the exterior film material 1A so that the top sides 12 face each other in parallel. Thereby, since the top 12 is inclined with respect to the bottom 11, the top 12 faces in the width direction of the exterior film material 1 </ b> A even though the top 12 is inclined with respect to the edge in the width direction of the exterior film material 1 </ b> A. The distance between the two exterior films 1 can be made as close as the case where the base 11 is parallel to the top 12. Thereby, it can avoid that the exterior film material 1A becomes the exterior film 1, and a useless part arises.
　図９～図１２は、本発明の変形例および他の実施形態を示している。なお、これらの図において、上記実施形態と同一または類似の要素には、上記実施形態と同一の符号を付している。 9 to 12 show a modified example and other embodiments of the present invention. In these drawings, the same or similar elements as those in the above embodiment are denoted by the same reference numerals as those in the above embodiment.
　図９は、パウチ容器用包材Ａ１の変形例を示している。本変形例においては、天辺１２が非直線状とされている。より具体的には、天辺１２は、複数の凹凸によって構成される波線形状とされている。本変形例においても、上述したマージンＭｇの設定方法に則って、天辺１２が底辺１１に対して傾いた構成とされている。天辺１２が波線形状である場合、たとえば天辺１２のうち図中上方の複数の凸部の頂点の包括線を規定する。そして、この包括線（図中想像線）と底辺１１との関係を、上述した傾いた関係とすればよい。図１０は、図９に示すパウチ容器用包材Ａ１の変形例を用いたパウチ容器Ｂ１を示している。
このパウチ容器Ｂ１においては、天辺１２の包括線（図中想像線）と底辺１１とが平行か、より平行に近い状態となっている。この包括線が底辺１１と平行であるほど、パウチ容器Ｂ１を陳列した際などにパウチ容器Ｂ１の外観を美麗に保つことができる。 FIG. 9 shows a modification of the packaging material A1 for a pouch container. In the present modification, the top 12 is non-linear. More specifically, the top 12 has a wavy shape constituted by a plurality of irregularities. Also in the present modification, the top 12 is inclined with respect to the bottom 11 in accordance with the above-described margin Mg setting method. When the top 12 is a wavy line shape, for example, a comprehensive line at the apexes of a plurality of convex portions on the top of the top 12 in the figure is defined. Then, the relationship between the inclusion line (imaginary line in the figure) and the base 11 may be the inclined relationship described above. FIG. 10 shows a pouch container B1 using a modification of the pouch container packaging material A1 shown in FIG.
In this pouch container B1, the inclusive line (imaginary line in the figure) of the top 12 and the bottom 11 are parallel or closer to parallel. The more parallel this inclusion line is to the bottom 11, the more beautiful the appearance of the pouch container B1 is when the pouch container B1 is displayed.
　本変形例から理解されるように、本発明においては天辺１２の形状は直線状に限定されない。上述したように非直線状の天辺１２であっても、その形状の特徴をなす部位の包括線や、中心線などが規定される場合、これらの包括線や中心線と底辺１１との関係がパウチ容器Ｂ１の外観に顕著な影響を与える。したがって、非直線状の天辺１２についても本発明における構成を適用することにより、パウチ容器Ｂ１の外観をより美麗に保ち、このようなパウチ容器Ｂ１を適切に製造できるという効果を奏する。この点は、以下に説明する実施形態についても同様である。 As can be understood from the present modification, the shape of the top 12 is not limited to a straight line in the present invention. As described above, even in the case of the non-linear top 12, when a comprehensive line, a center line, or the like of a part that characterizes the shape is defined, the relationship between these comprehensive lines or the central line and the base 11 is Significantly affects the appearance of the pouch container B1. Therefore, by applying the configuration of the present invention also to the non-linear top 12, the appearance of the pouch container B1 can be kept more beautiful, and such a pouch container B1 can be appropriately manufactured. This also applies to the embodiments described below.
　図１１は、本発明の第二実施形態に基づくパウチ容器用包材を示している。本実施形態のパウチ容器用包材Ａ２は、第二側辺１４の構成が上述した実施形態と異なっている。本実施形態においては、第二側辺１４は、垂直部１４１および天側垂直部１４３からなる。
垂直部１４１は、底辺１１側に位置し、底辺１１に対して垂直である。天側垂直部１４３は、天辺１２側に位置し、底辺１１に対して垂直である。すなわち、第二側辺１４は、全体として底辺１１に垂直な直線状とされている。垂直部１４１と天側垂直部１４３とは、幾何形状に由来する区別は特に無く、第二側辺１４のうち第二側方シール部１７１が形成された部分が垂直部１４１と定義される。 FIG. 11 shows a packaging material for a pouch container according to the second embodiment of the present invention. The packaging material A2 for the pouch container of the present embodiment is different from the above-described embodiment in the configuration of the second side 14. In the present embodiment, the second side 14 includes a vertical part 141 and a top vertical part 143.
The vertical portion 141 is located on the base 11 side and is perpendicular to the base 11. The top vertical part 143 is located on the top 12 side and is perpendicular to the bottom 11. That is, the second side 14 is linearly formed perpendicular to the bottom 11 as a whole. The vertical portion 141 and the top side vertical portion 143 are not particularly distinguished from each other due to the geometric shape, and the portion of the second side 14 where the second side seal portion 171 is formed is defined as the vertical portion 141.
　パウチ容器用包材Ａ２を用いたパウチ容器の製造方法においても、側方開口部１７０にスパウト３の拡幅部３２が挿入される。この拡幅部３２を挟んで一対の外装フィルム１を接合すると、上述した実施形態と同様に、天側垂直部１４３が平面視において見かけ上短縮される。このため、本実施形態においても、パウチ容器用包材Ａ２には、マージンＭｇが上述した設定例と同様の思想によって設定されており、天辺１２が底辺１１に対して傾いた構成とされている。図１２は、このようなパウチ容器用包材Ａ２を用いて製造されたパウチ容器Ｂ２を示している。パウチ容器Ｂ２においても、天辺１２が底辺１１に対して平行か、平行により近い状態とされている。したがって、パウチ容器Ｂ２の外観を美麗にするとともに、パウチ容器Ｂ２を適切に製造することができる。 Also in the manufacturing method of the pouch container using the packaging material A2 for the pouch container, the widened portion 32 of the spout 3 is inserted into the side opening 170. When the pair of exterior films 1 are bonded with the widened portion 32 interposed therebetween, the top vertical portion 143 is apparently shortened in a plan view as in the above-described embodiment. For this reason, also in this embodiment, the margin Mg is set in the pouch container packaging material A2 based on the same idea as in the setting example described above, and the top 12 is inclined with respect to the bottom 11. . FIG. 12 shows a pouch container B2 manufactured using such a pouch container packaging material A2. Also in the pouch container B <b> 2, the top side 12 is parallel to or closer to the base 11. Therefore, the appearance of the pouch container B2 can be made beautiful, and the pouch container B2 can be appropriately manufactured.
　本発明に係るパウチ容器用包材およびパウチ容器の製造方法は、上述した実施形態に限定されるものではない。本発明に係るパウチ容器用包材およびパウチ容器の製造方法の具体的な構成は、種々に設計変更自在である。 The pouch container packaging material and the method for manufacturing the pouch container according to the present invention are not limited to the above-described embodiments. The specific structure of the packaging material for a pouch container and the method for manufacturing the pouch container according to the present invention can be changed in various ways.
