Description

本発明は、パウチ本体にスパウトを取り付けたスパウト付きパウチに関する。   The present invention relates to a pouch with a spout in which a spout is attached to a pouch body.

従来のこの種のスパウト付きパウチは、剛性の高いスパウトとしなやかなフィルムによって構成されるパウチ本体とを熱融着させて結合している。
図４には、従来の一般的なスパウト付きパウチを示している。すなわち、このスパウト付きパウチは、可撓性のフィルムを重ね合わせて成形される袋体であって継ぎ目となるフィルム端部間が熱溶着されてシールされるパウチ本体１０１と、パウチ本体１０１のフィルム端部間に装着されフィルム端部と共に熱溶着されてシールされるスパウト１０３と、を備えた構成となっている。 This type of conventional pouch with a spout is bonded to a pouch body constituted by a highly rigid spout and a flexible film by heat fusion.
FIG. 4 shows a conventional general pouch with a spout. That is, this pouch with a spout is a pouch body 101 formed by superposing flexible films, and a film end of the pouch body 101 is sealed by heat-sealing between the film end portions that become seams. And a spout 103 mounted between the end portions and thermally welded together with the film end portions to be sealed.

しかし、パウチ本体１０１内部の収納空間に面する変形自在のフィルム部１０４と、型成形品であるスパウト１０３との間には剛性差があるために、内容物の圧力が上昇したり、落下時などの衝撃により、パウチ本体１０１の内圧が高くなった際に、フィルム部１０４が大きく膨らみ、スパウトシール部１０２とフィルム部１０４との境界部１０５に応力が集中しやすい。特に、スパウト１０３の左右のエッジ部１０３ａとスパウトシール部１０２の内縁部に位置する境界部１０５との交点Ｐ付近に応力が集中し、この付近においてフィルムが破断するおそれがある。さらに、スパウト１０３のスパウトシール部１０２は、熱溶着時の熱と圧力によりフィルムが薄肉化しており、応力集中と相俟ってフィルムが破断するおそれが高い。
このように、スパウト付きパウチは、スパウトを装着していないパウチに比べて耐圧性及び耐落下衝撃性に劣るという問題があった。 However, since there is a difference in rigidity between the deformable film portion 104 facing the storage space inside the pouch body 101 and the spout 103 which is a molded product, the pressure of the contents increases or falls. When the internal pressure of the pouch main body 101 increases due to an impact such as the above, the film portion 104 swells greatly, and stress tends to concentrate on the boundary portion 105 between the spout seal portion 102 and the film portion 104. In particular, stress concentrates in the vicinity of the intersection P between the left and right edge portions 103a of the spout 103 and the boundary portion 105 located at the inner edge of the spout seal portion 102, and there is a possibility that the film breaks in this vicinity. Further, the spout seal portion 102 of the spout 103 has a thin film due to heat and pressure at the time of heat welding, and there is a high possibility that the film breaks due to stress concentration.
Thus, the pouch with a spout has a problem that it is inferior in pressure resistance and drop impact resistance compared to a pouch not equipped with a spout.

また、従来のスパウト付きパウチでは、スパウト１０３近傍は内容物を取り出す際に、パウチ本体１０１の表裏面のフィルム部１０４がくっついて自己閉塞を起こしやすく、内容物を取り出しにくいという問題もあった。
自己閉塞を防止するために、従来は板状あるいは棒状の自己閉塞防止具１０６が挿入されているが、その分だけ部品点数が増大すると共にコストも嵩む。また、自己閉塞防止具はスパウトと一体に成形されることもあり成形が困難である。 Further, in the conventional pouch with a spout, when the contents are taken out in the vicinity of the spout 103, the film portions 104 on the front and back surfaces of the pouch main body 101 stick to each other, so that self-occlusion easily occurs, and the contents are difficult to take out.
In order to prevent self-occlusion, a plate-like or bar-like self-occlusion prevention device 106 is conventionally inserted. However, the number of parts increases and the cost increases accordingly. In addition, the self-occlusion prevention device is sometimes molded integrally with the spout and is difficult to mold.

スパウトのエッジ部の応力集中を防止する技術としては、従来から特許文献１に記載のようなものが知られている。この特許文献１では、熱溶着されるスパウトの内縁部の形状を中央部からエッジ部に向けて凹となるように円弧状とし、応力を円弧形状の部分に分散させてエッジ部に集中しないように構成している。
しかし、特許文献１に記載のものでは、スパウトを特別の形状に加工する必要があり、既存のスパウト付きパウチに適用することができない。また、スパウト付近の自己閉塞に関しても解決することができなかった。
特開平０７−２５１８８１号公報 As a technique for preventing stress concentration at the edge of the spout, a technique as described in Patent Document 1 has been known. In Patent Document 1, the shape of the inner edge portion of the spout to be thermally welded is an arc shape so as to be concave from the center portion toward the edge portion, and stress is distributed to the arc shape portion so as not to concentrate on the edge portion. It is configured.
However, in the thing of patent document 1, it is necessary to process a spout into a special shape, and cannot apply to the existing pouch with a spout. In addition, self-occlusion near the spout could not be solved.
Japanese Patent Laid-Open No. 07-251881

本発明は上記した従来技術の課題を解決するためになされたもので、主たる目的は、簡単な構成でスパウトシール部の境界部に集中する応力を分散させ得るスパウト付きパウチを提供し、もって、耐圧性，耐落下衝撃性を向上させることにある。   The present invention has been made to solve the above-described problems of the prior art, and a main object is to provide a pouch with a spout that can disperse stress concentrated on the boundary portion of the spout seal portion with a simple configuration, The purpose is to improve pressure resistance and drop impact resistance.

上記目的を達成するために、本発明は、可撓性のフィルムを重ね合わせて成形される袋体であって継ぎ目となるフィルム端部間が熱溶着されてシールされるパウチ本体と、該パウチ本体のフィルム端部間に装着されフィルム端部と共に熱溶着されてシールされるスパウトと、を備えたスパウト付きパウチにおいて、
前記パウチ本体外面に、スパウトの熱溶着部とパウチ本体の収納空間に面する変形自在のフィルム部との境界部を跨いで、スパウトの熱溶着部と変形自在のフィルム部の双方を部分的に覆うように貼り付けられる応力分散片を設けたことを特徴とする。 In order to achieve the above object, the present invention provides a pouch body that is formed by stacking flexible films and is sealed by heat-sealing between film end portions that become seams, and the pouch. In a pouch with a spout equipped with a spout attached between the film end portions of the main body and thermally welded and sealed together with the film end portions,
The outer surface of the pouch body partially spans the boundary between the heat-welded part of the spout and the deformable film part facing the storage space of the pouch body, and partially covers both the heat-welded part of the spout and the deformable film part. It is characterized by providing a stress dispersion piece to be attached so as to cover it.

応力分散片は、スパウトの左右エッジ部と、スパウトの熱溶着部とフィルム部との境界部との交点を覆うように設けられていることが好ましい。
また、応力分散片はスパウトの形状に倣った立体形状を有していることが好適である。 さらに、応力分散片の変形自在のフィルム部側に貼り付けられる部分の外周形状は滑らかな曲線形状となっていることが好ましい。 The stress dispersion piece is preferably provided so as to cover the intersection of the left and right edge portions of the spout and the boundary portion between the heat welded portion of the spout and the film portion.
Moreover, it is preferable that the stress dispersion piece has a three-dimensional shape that follows the shape of the spout. Furthermore, it is preferable that the outer peripheral shape of the portion attached to the deformable film portion side of the stress dispersion piece is a smooth curved shape.

応力分散片表面にエンボス部あるいは穴の滑り止め手段を設けてもよい。
また、応力分散片に剛性を調整する剛性調整手段を設けてもよい。
この場合、応力分散片の変形自在のフィルム部側に貼り付けられる部分について、外周縁に向かって剛性が小さくなる構成とすることが好ましい。
剛性を小さくする手段としては、応力分散片のフィルム部側に貼り付けられる部分の外周縁に多数のスリットを設けてもよいし、肉厚が外周縁に向かって徐々に薄肉となるように構成してもよい。
また、応力分散片はパウチ本体と同材質の材料によって構成することが好適である。 An embossed part or a hole slip prevention means may be provided on the surface of the stress dispersion piece.
Moreover, you may provide the rigidity adjustment means which adjusts rigidity to a stress distribution piece.
In this case, it is preferable that the portion of the stress dispersion piece that is affixed to the deformable film portion side has a configuration in which the rigidity decreases toward the outer peripheral edge.
As means for reducing the rigidity, a large number of slits may be provided on the outer peripheral edge of the portion to be affixed to the film portion side of the stress dispersion piece, and the thickness is gradually reduced toward the outer peripheral edge. May be.
Further, it is preferable that the stress dispersion piece is made of the same material as the pouch body.

本発明によれば、内容物の熱膨張や落下時の衝撃によりパウチ本体の内圧が上昇しても、応力分散片によって応力が分散され、スパウトの熱溶着部とフィルム部の境界部、特にスパウトの左右エッジ部と境界部との交点に集中せず、フィルムの破断を防止できる。
また、応力分散片を設けることにより適度な剛性が生じるので、スパウト付け根部のパウチ本体の自己閉塞を防止できる。
さらに、応力分散片の剛性により、応力分散片をパウチを手に持つ際の把持部として用いることができ、使い勝手がよい。
また、応力分散片をパウチ本体の外面に装着するため、応力分散片の材質により内容物へ影響を与えることがない。
また、応力分散片の形、色、さらに加飾を施すことにより、差別化を図ることもできる。
特に、応力分散片を、スパウトの左右エッジ部とスパウトの熱溶着部の交点を覆うように設ければ、フィルムの破断を効果的に防止することができる。 According to the present invention, even if the internal pressure of the pouch body increases due to the thermal expansion of the contents or the impact at the time of dropping, the stress is dispersed by the stress dispersion piece, and the boundary portion between the heat welded portion of the spout and the film portion, particularly the spout The film can be prevented from breaking without being concentrated at the intersection of the left and right edge portions and the boundary portion.
Moreover, since moderate rigidity arises by providing the stress dispersion piece, the self-occlusion of the pouch body at the base portion of the spout can be prevented.
Furthermore, due to the rigidity of the stress dispersion piece, the stress dispersion piece can be used as a gripping part when holding the pouch in the hand, which is easy to use.
Further, since the stress dispersion piece is mounted on the outer surface of the pouch body, the contents are not affected by the material of the stress dispersion piece.
Differentiation can also be achieved by applying a shape, color, and decoration of the stress dispersion piece.
In particular, if the stress dispersion piece is provided so as to cover the intersection of the left and right edge portions of the spout and the heat welded portion of the spout, it is possible to effectively prevent the film from being broken.

応力分散片をスパウトの形状に倣った立体形状としておけば、貼り付け作業が容易である。
また、応力分散片のフィルム部側に貼り付けられる部分の外周縁形状を角部の無いなめらかな曲線にしておくことにより、応力分散片の外周縁部に応力が集中するおそれが無い。 さらに、応力分散片表面に滑り止め手段を設けることにより、応力分散片を手で握った際に滑りにくく、より使い勝手が向上する。 If the stress dispersion piece has a three-dimensional shape following the shape of the spout, the pasting operation is easy.
In addition, by making the shape of the outer peripheral edge of the portion attached to the film portion side of the stress dispersion piece a smooth curve having no corners, there is no risk of stress concentration on the outer peripheral edge portion of the stress dispersion piece. Furthermore, by providing a non-slip means on the surface of the stress dispersion piece, it is difficult to slip when the stress dispersion piece is gripped by hand, and the usability is further improved.

また、スリットや穴加工等の剛性調整手段によって、簡単に応力分散片の柔軟性をコントロールできる。
特に、応力分散片のフィルム部側に貼り付けられる部分の外周縁部に、スリットを設けたり、肉厚を徐々に薄肉としておくことにより、フィルム部の柔軟性を損なうことなく、応力を効率的に分散させることができる。
応力分散片をパウチ本体と同材質とすれば、廃棄時の分別の問題が無い。 Further, the flexibility of the stress dispersion piece can be easily controlled by means of stiffness adjustment such as slitting or hole machining.
In particular, by providing slits on the outer peripheral edge of the part to be attached to the film part side of the stress dispersion piece or by gradually reducing the thickness, stress can be efficiently applied without losing the flexibility of the film part. Can be dispersed.
If the stress dispersion piece is made of the same material as the pouch body, there is no problem of separation at the time of disposal.

以下に本発明を図示の実施の形態に基づいて説明する。
実施例１
図１は本発明の実施例１に係るスパウト付きパウチを示している。
このスパウト付きパウチは、可撓性のフィルムを重ね合わせて成形される袋体であって継ぎ目となるフィルム端部間が熱溶着されてシールされるパウチ本体１と、パウチ本体１のフィルム端部間に装着されフィルム端部と共に熱溶着されてシールされるスパウト３と、を備えている。パウチ本体１外面には、スパウト３の熱溶着部としてのスパウトシール部２とパウチ本体１の内部空間に面する変形自在のフィルム部５との境界部６を跨いで、スパウト３のスパウトシール部２と変形自在のフィルム部５の双方を部分的に覆うように貼り付けられる応力分散片としての応力分散パッチ４が設けられている。 The present invention will be described below based on the illustrated embodiments.
Example 1
FIG. 1 shows a pouch with a spout according to a first embodiment of the present invention.
This pouch with a spout is a pouch body formed by overlapping flexible films, and a pouch body 1 that is heat-sealed between the film end portions that become seams and sealed, and a film end portion of the pouch body 1 And a spout 3 which is attached between and thermally welded together with the film end. On the outer surface of the pouch body 1, the spout seal portion of the spout 3 is straddled across the boundary portion 6 between the spout seal portion 2 as a heat welding portion of the spout 3 and the deformable film portion 5 facing the inner space of the pouch body 1. A stress distribution patch 4 is provided as a stress distribution piece that is affixed so as to partially cover both the film 2 and the deformable film part 5.

パウチ本体１は、図示例ではいわゆるガゼット袋形式で、図１（Ｃ）に示すように、表裏一対の平面フィルム１１，１１と、左右側面の縦に折り曲げられた二つ折りの側面フィルム１２，１２とから構成されている。
平面フィルム１１，１１の左右側縁に二つ折りの側面フィルム１２，１２の前後縁部が熱溶着されて側辺シール部１３，１３が構成されている（図１（Ａ），（Ｂ）参照）。平面フィルム１１，１１の側辺は、底辺側の下方部分が内側に向けて斜めに屈曲する屈曲形状となっている。 In the illustrated example, the pouch body 1 is in the form of a so-called gusset bag. As shown in FIG. 1 (C), the pair of front and back flat films 11 and 11 and the side films 12 and 12 folded in half vertically on the left and right sides. It consists of and.
The front and rear edge portions of the folded side films 12 and 12 are thermally welded to the left and right side edges of the flat films 11 and 11 to form side seal portions 13 and 13 (see FIGS. 1A and 1B). ). The sides of the flat films 11 and 11 have a bent shape in which the lower part on the bottom side is bent obliquely inward.

一方、側面フィルム１２，１２の上側縁は平面フィルム１１，１１の上側縁に熱溶着されて上辺シール部１４が形成され（図１（Ａ）参照）、左右の上辺シール部１４，１４の間の平面フィルム１１，１１の上側縁中央部に、スパウト３が熱溶着されてスパウトシール部２が形成されている。このスパウトシール部２は左右の上辺シール部１４，１４と連続している。
また、平面フィルム１１，１１の下側縁の中央部が熱溶着されて底辺シール部１５が形成されている。
パウチ本体１を構成するフィルム材は特に限定されないが、フィルムがアルミ箔層を含まない構造の場合にエッジ切れが生じやすいので、アルミ箔層を含まないフィルム材に好適である。 On the other hand, the upper edges of the side films 12 and 12 are thermally welded to the upper edges of the flat films 11 and 11 to form the upper side seal portion 14 (see FIG. 1A), and between the left and right upper side seal portions 14 and 14. The spout 3 is thermally welded to the center portion of the upper edge of the flat films 11 and 11 to form the spout seal portion 2. The spout seal portion 2 is continuous with the left and right upper side seal portions 14 and 14.
Moreover, the bottom part seal part 15 is formed by heat-welding the center part of the lower edge of the flat films 11 and 11.
Although the film material which comprises the pouch main body 1 is not specifically limited, Since edge cut | disconnection tends to produce in the case of the structure where a film does not contain an aluminum foil layer, it is suitable for the film material which does not contain an aluminum foil layer.

スパウト３は、図１（Ａ），（Ｂ）に示すように、横断面形状が舟形あるいは紡錘形状の基部３１と、この基部３１から上方に突出する注出筒３２とを備え、注出筒３２がキャップ３３によって閉塞されるように構成されている。
基部３１は、図１（Ｃ）に示すように、注出孔３４が貫通している中央部３５から左右両端の尖ったエッジ部３ａ，３ａに向かって徐々に厚みが薄肉になるように延びる延出部３６を備えており、スパウトシール部２のフィルム端部は基部３１の横断面形状に倣って舟形あるいは紡錘形状となっている。 As shown in FIGS. 1 (A) and 1 (B), the spout 3 includes a base 31 having a boat-shaped or spindle-shaped cross section, and a pouring cylinder 32 protruding upward from the base 31. 32 is configured to be closed by a cap 33.
As shown in FIG. 1C, the base 31 extends from the central portion 35 through which the pouring hole 34 penetrates toward the sharp edge portions 3a, 3a at both the left and right ends so that the thickness gradually decreases. The extending portion 36 is provided, and the film end portion of the spout seal portion 2 has a boat shape or a spindle shape following the cross-sectional shape of the base portion 31.

応力分散パッチ４は、図１（Ａ）に示すように、円弧部４１と円弧部４１の両端を結んだ直線部４２で囲まれる円弧面形状のプラスチックス製の小片によって構成されている。直線部４２の長さはスパウトシール部２だけでなく、左右の上辺シール部１４，１４の端までパウチ本体１のほぼ全幅分の長さを有し、円弧部４１側がスパウトシール部２及び上辺シール部１４と変形自在のフィルム部５との境界部６を越えてフィルム部５側に所定寸法だけ張り出し、スパウト３の左右のエッジ部３ａ，３ａとスパウトシール部２の内縁部である境界部６の交点部分Ｐを含め、スパウトシール部２と上辺シール部１４の境界部６付近の領域を大きく覆っている。もっとも、応力を分散させる構成であればよく、たとえば、図１（Ｄ）に示すように、エッジ部３ａと境界部６の交点部分Ｐに対応する部分に透孔４４が設けられていてもよい。   As shown in FIG. 1A, the stress distribution patch 4 is configured by a small piece made of plastic having an arc surface shape surrounded by an arc portion 41 and a straight portion 42 connecting both ends of the arc portion 41. The length of the straight line portion 42 is not only the spout seal portion 2 but also the length of almost the entire width of the pouch body 1 up to the ends of the left and right upper side seal portions 14, 14. A boundary portion that protrudes beyond the boundary portion 6 between the seal portion 14 and the deformable film portion 5 to the film portion 5 side by a predetermined dimension and is an inner edge portion of the left and right edge portions 3a, 3a of the spout 3 and the spout seal portion 2. The region near the boundary portion 6 between the spout seal portion 2 and the upper side seal portion 14 including the intersection portion P of 6 is greatly covered. Of course, any structure may be used as long as the stress is dispersed. For example, as shown in FIG. 1D, a through hole 44 may be provided in a portion corresponding to the intersection P between the edge portion 3 a and the boundary portion 6. .

また、応力分散パッチ４には、図１（Ｃ）に示すように、スパウト３の形状に倣った立体形状、図示例ではスパウト３の基部３１の横断面形状に倣った半紡錘形状あるいは半舟形形状の立体形状部４Ｔを備え、スパウトシール部２に密接している。
応力分散パッチ４の貼り付けは、接着剤，粘着剤によって貼り付けられる。両面テープによって貼り付けてもよく、材料によっては熱融着してもよい。要するに、パウチ本体１の表面に密着して剥がれなければよい。
図示例では、応力分散パッチ４の外周形状は、一つの円弧部４１と一つの直線部４２で構成されて円弧面形状となっているが、フィルム部側に貼り付けられる部分の外周形状が滑らかな曲線で構成されていればよい。たとえば、図１（Ｅ）に示すように、円弧部４１と直線部４２が左右直線部４３，４３を介してつながるような形状でもよいし、図１（Ｆ）に示すように、円弧部の代わりに直線部４２と平行なフィルム部側直線部４５を有し、左右直線部４３，４３とフィルム部側直線部４５の角部を丸めて円弧部４６とした角丸の四角形状としてもよいし、その他種々の形状を採用し得る。 Further, as shown in FIG. 1C, the stress distribution patch 4 has a three-dimensional shape that follows the shape of the spout 3, and in the illustrated example, a semi-spindle shape or a half-boat shape that follows the cross-sectional shape of the base 31 of the spout 3. A solid three-dimensional part 4T is provided and is in close contact with the spout seal part 2.
The stress dispersion patch 4 is attached with an adhesive or a pressure-sensitive adhesive. You may affix with a double-sided tape, and depending on material, you may heat-seal. In short, it is only necessary that the pouch body 1 is not in close contact with the surface of the pouch body 1 and peeled off.
In the illustrated example, the outer peripheral shape of the stress distribution patch 4 is formed by one arc portion 41 and one linear portion 42 and has an arc surface shape, but the outer peripheral shape of the portion to be attached to the film portion side is smooth. What is necessary is just to be comprised by a simple curve. For example, as shown in FIG. 1 (E), the arc portion 41 and the straight portion 42 may be connected via the left and right straight portions 43, 43, or as shown in FIG. Instead, the film portion side straight portion 45 parallel to the straight portion 42 may be provided, and the corners of the left and right straight portions 43 and 43 and the film portion side straight portion 45 may be rounded to form a rounded square shape having an arc portion 46. In addition, various other shapes can be adopted.

応力分散パッチ４の材料としては、たとえば、ポリプロピレン，ポリエチレン等の各種プラスチック材が適用可能であるし、複数の材料を積層した積層体構造としてもよい。プラスチック材に限定されるものではなく、応力を分散できる程度の剛性がある材料であれば、紙，ゴム，金属、木材，布等、種々の材料が利用可能である。もっとも、パウチ本体１、スパウト３に使用する材料と同材質の樹脂材を用いれば、廃棄時の分別の問題が無く、廃棄性に優れている。   As a material of the stress dispersion patch 4, for example, various plastic materials such as polypropylene and polyethylene are applicable, and a laminated structure in which a plurality of materials are laminated may be used. The material is not limited to a plastic material, and various materials such as paper, rubber, metal, wood, and cloth can be used as long as the material has rigidity sufficient to disperse stress. However, if a resin material of the same material as that used for the pouch body 1 and the spout 3 is used, there is no problem of separation at the time of disposal, and the disposal property is excellent.

応力分散パッチ４の厚さは適度の剛性を有する厚みがあればよく、材質，大きさ等を勘案して適宜設定される。厚すぎると剛性が大きくなりすぎて応力分散パッチとフィルム部側貼り付け部の外周円に応力が集中する結果となるし、薄すぎると応力分散効果が小さくなってしまう。種々検討した結果、パウチの容量が１００ｍｌ程度であって、パッチの材質がプラスチックの場合には０．５ｍｍ程度が好適である。また、応力分散パッチ４に、図２（Ａ）に示すように、剛性調整手段としての複数の穴４７を形成すれば、簡単に応力分散パッチ４の柔軟性をコントロールできるとともに、持った時の滑り止め効果もある。   The thickness of the stress dispersion patch 4 may be a thickness having an appropriate rigidity, and is appropriately set in consideration of the material, size, and the like. If it is too thick, the rigidity becomes too large, resulting in stress being concentrated on the outer periphery circle of the stress dispersion patch and the film portion side application portion, and if it is too thin, the stress dispersion effect is reduced. As a result of various investigations, when the capacity of the pouch is about 100 ml and the material of the patch is plastic, about 0.5 mm is preferable. In addition, as shown in FIG. 2A, if the stress distribution patch 4 is formed with a plurality of holes 47 as rigidity adjusting means, the flexibility of the stress distribution patch 4 can be easily controlled, and when it is held There is also a non-slip effect.

上記実施例に係るスパウト付きパウチによれば、内容物の熱膨張や落下時の衝撃によりパウチ本体１の内圧が上昇してパウチ本体１が膨らんでも、応力分散パッチ４によってパウチ本体１のスパウト３の左右エッジ部３ａ，３ａとスパウトシール部２とフィルム部５との境界部６との交点部Ｐ周辺のフィルム部分５の変形が押さえられ、応力が左右エッジ部３ａ，３ａと境界部６の交点部Ｐに集中しないので、境界部６から交点部Ｐ周辺でのエッジ切れを防止できる。
また、応力分散パッチ４のフィルム部５に張り出す部分の外周形状が円弧部４１で、角部の無いなめらかな曲線形状となっているので、応力分散パッチ４の外周に応力が集中するおそれも無い。 According to the pouch with a spout according to the above embodiment, even if the internal pressure of the pouch body 1 rises due to the thermal expansion of the contents or the impact at the time of dropping, the pouch body 1 swells, and the spout 3 of the pouch body 1 by the stress distribution patch 4. The deformation of the film portion 5 around the intersection P between the right and left edge portions 3a and 3a, the spout seal portion 2 and the boundary portion 6 of the film portion 5 is suppressed, and stress is applied to the left and right edge portions 3a and 3a and the boundary portion 6. Since it does not concentrate on the intersection P, it is possible to prevent edge breakage from the boundary 6 around the intersection P.
In addition, since the outer peripheral shape of the portion of the stress dispersion patch 4 that protrudes from the film portion 5 is a circular arc portion 41 and has a smooth curved shape without corner portions, there is a possibility that stress concentrates on the outer periphery of the stress distribution patch 4. No.

応力分散パッチ４のフィルム部側貼り付け部外周縁の円弧部４１に応力が集中しないように、図２（Ｂ）に示すように、多数のスリット４８を設けて剛性を小さくしたり、図２（Ｃ）に示すように、肉厚ｔを外周に向かって徐々に薄肉として剛性が小さくなる構成としてもよい。
また、応力分散パッチ４を設けることにより適度な剛性が生じるので、内容物を注出して内圧が減少しても、応力分散パッチ４によってフィルム部５が保持され、スパウト付け根部におけるパウチ本体１の自己閉塞も防止できる。したがって、従来用いられていた自己閉塞防止具が不要となる。 As shown in FIG. 2 (B), a large number of slits 48 are provided to reduce the rigidity so that the stress does not concentrate on the arc portion 41 on the outer peripheral edge of the film portion side attaching portion of the stress dispersion patch 4. As shown in (C), the thickness t may be gradually reduced toward the outer periphery to reduce the rigidity.
In addition, since moderate rigidity is generated by providing the stress distribution patch 4, the film portion 5 is held by the stress distribution patch 4 even if the content is poured out and the internal pressure is reduced, and the pouch body 1 of the spout base portion is maintained. Self-occlusion can also be prevented. Therefore, the conventionally used self-occlusion prevention tool becomes unnecessary.

さらに、応力分散パッチ４が適度な剛性を有しているので、応力分散パッチ４を手で把持する把持部としても用いることができ、また、持つ位置も広がる。応力分散パッチ４表面には、エンボス部加工等により凹凸を付けておけば、滑り止め手段として機能として一層持ちやすくなる。
応力分散パッチ４はパウチ本体１の外表面に装着するため、既存のすべてのスパウト付きパウチに対して適用可能であるし、応力分散パウチ２の材質により内容物へ影響を与えることがない。
また、応力分散パッチ４の形、色、さらに加飾を施すことにより差別化を図ることもできる。 Furthermore, since the stress distribution patch 4 has appropriate rigidity, the stress distribution patch 4 can be used as a grip portion for gripping the stress distribution patch 4 by hand, and the position of the stress distribution patch 4 is also widened. If the surface of the stress distribution patch 4 is uneven by embossing or the like, it becomes easier to have a function as a non-slip means.
Since the stress distribution patch 4 is attached to the outer surface of the pouch main body 1, it can be applied to all existing pouches with a spout, and the contents are not affected by the material of the stress distribution pouch 2.
Differentiation can also be achieved by giving the shape and color of the stress distribution patch 4 and further decoration.

図２（Ｄ），（Ｅ）は応力分散パッチの変形例を示している。
上記実施例では、応力分散パッチ４は、スパウトシール部だけでなく左右の上辺シール部１４，１４とフィルム部６との境界部５全体を広く覆うように構成されているが、図２（Ｄ）のようにスパウト３の左右のエッジ部３ａ，３ａと境界部５の交点Ｐ付近のみを覆うようにしてもよい。 2D and 2E show modifications of the stress distribution patch.
In the above embodiment, the stress distribution patch 4 is configured to cover not only the spout seal portion but also the entire boundary portion 5 between the left and right upper side seal portions 14 and 14 and the film portion 6, but FIG. Only the vicinity of the intersection P between the left and right edge portions 3a, 3a and the boundary portion 5 of the spout 3 may be covered as shown in FIG.

この変形例の応力分散パッチ１４０は略Ｔ字形状で、スパウトシール部２から左右の上辺シール部１４，１４の端部付近まで延びる横方向パッチ片部１４１と、スパウトシール部に対応する幅の中央の縦方向パッチ片部１４２とによって構成されている。縦方向パッチ片部１４２はスパウトシール部２の境界部６を越えて所定寸法だけ変形自在のフィルム部５側に延びている。横方向パッチ片部１４１の下側辺はスパウトシール部２及び左右の上辺シール部１４の下側辺に沿って延びており、縦方向パッチ片部１４２の左右側縁は凹状の円弧形状となっている。円弧形状部１４３はほぼ４分の１円弧で、一端が縦方向パッチ片部１４２の角部に位置し、他端が横方向パッチ片部１４１の下側縁につながる滑らかな曲線形状となっている。縦方向パッチ片部１４２の角部も丸めておくことが好適である。
円弧形状部１４３によって、スパウト３の左右のエッジ部３ａ，３ａと境界部６の交点Ｐ周辺が覆われている。
このようにすれば、パウチ本体１が内圧上昇により膨れた場合に、スパウトシール部２の境界部６付近のフィルム部の変形は応力分散パッチ４の縦方向突出部１４２によって押さえられ、応力が円弧形状部１４３に沿って分散されるので、フィルムのエッジ切れを防止することができる。 The stress distribution patch 140 of this modification is substantially T-shaped, and has a lateral patch piece portion 141 extending from the spout seal portion 2 to the vicinity of the end portions of the left and right upper side seal portions 14, and a width corresponding to the spout seal portion. It is constituted by a central longitudinal patch piece 142. The longitudinal patch piece 142 extends beyond the boundary portion 6 of the spout seal portion 2 to the side of the film portion 5 that can be deformed by a predetermined dimension. The lower side edge of the lateral patch piece portion 141 extends along the lower side edge of the spout seal portion 2 and the left and right upper side seal portion 14, and the left and right side edges of the vertical patch piece portion 142 have a concave arc shape. ing. The arc-shaped portion 143 is a substantially one-quarter arc, and has a smooth curved shape in which one end is located at the corner of the vertical patch piece 142 and the other end is connected to the lower edge of the horizontal patch piece 141. Yes. It is also preferable to round the corners of the longitudinal patch piece 142.
The arc-shaped portion 143 covers the periphery of the intersection P between the left and right edge portions 3 a and 3 a and the boundary portion 6 of the spout 3.
In this way, when the pouch body 1 swells due to an increase in internal pressure, the deformation of the film portion in the vicinity of the boundary portion 6 of the spout seal portion 2 is suppressed by the longitudinal projecting portion 142 of the stress dispersion patch 4, and the stress is circulated in an arc. Since it is dispersed along the shape portion 143, it is possible to prevent the edge of the film from being cut.

図２（Ｅ）は、応力分散パッチ１５０を略逆Ｔ字形状としたもので、縦方向に延びる縦方向パッチ片部１５１と、縦方向パッチ片部１５１の下端部から左右に延びる横方向パッチ片部１５２と、を備えている。縦方向パッチ片部１５１はスパウト３とほぼ同一幅で、スパウトシール部２の境界部６から所定量フィルム部５側に延びている。横方向パッチ片部１５２は、外周円弧部１５２ａと、外周円弧部１５２ａの左右両端から縦方向パッチ片部１５１の左右側縁に向かって斜めに延びる斜辺部１５２ｂとを有している。横方向パッチ片部１５２の左右両端部はスパウト３の中心線に対してスパウト３の左右エッジ部３ａ，３ａより外側に位置し、スパウト３の左右のエッジ部３ａ，３ａと境界部６の交点Ｐを横方向パッチ片部１５２と縦方向パッチ片部１５１と上辺シール部とによって３方を取り囲んでいる。
このようにすれば、パウチ本体１が内圧上昇により膨らんでも、スパウトシール部２の境界部６付近のフィルム部５の変形は、応力分散パッチ１５０の縦方向パッチ片部１５１と横方向パッチ片部１５２によって押さえられ、応力が横方向パッチ片部１５２全体に分散されるので、フィルムのエッジ切れを防止することができる。 FIG. 2E shows the stress distribution patch 150 having a substantially inverted T-shape. The longitudinal patch piece 151 extends in the longitudinal direction, and the lateral patch extends from the lower end of the longitudinal patch piece 151 to the left and right. One piece 152. The longitudinal patch piece 151 has substantially the same width as the spout 3 and extends from the boundary portion 6 of the spout seal portion 2 to the film portion 5 side by a predetermined amount. The lateral patch piece portion 152 has an outer circumferential arc portion 152a and an oblique side portion 152b extending obliquely from the left and right ends of the outer circumferential arc portion 152a toward the left and right side edges of the longitudinal patch piece portion 151. The left and right end portions of the lateral patch piece portion 152 are located outside the left and right edge portions 3 a and 3 a of the spout 3 with respect to the center line of the spout 3, and the intersection of the left and right edge portions 3 a and 3 a of the spout 3 and the boundary portion 6. P is surrounded on three sides by a lateral patch piece portion 152, a longitudinal patch piece portion 151, and an upper side seal portion.
In this way, even if the pouch body 1 swells due to an increase in internal pressure, the deformation of the film portion 5 in the vicinity of the boundary portion 6 of the spout seal portion 2 causes the longitudinal patch piece portion 151 and the lateral patch piece portion of the stress dispersion patch 150 to be deformed. Since the film is pressed by 152 and the stress is dispersed throughout the lateral patch piece 152, it is possible to prevent the edge of the film from being cut.

実施例２
図３は、本発明の実施例２に係るスパウト付きパウチを示している。
このスパウト付きパウチは、剛性の高い外装容器に収納され、スパウト２０３で外装容器２０７と固定するような構成となっており、外装容器２０７内に収納された状態でパウチが減容化される。
スパウト付きパウチは、可撓性のフィルムを重ね合わせて成形される袋体であって継ぎ目となるフィルム端部間が熱溶着されてシールされるパウチ本体２０１と、パウチ本体２０１のフィルム端部間に装着されフィルム端部と共に熱溶着されてシールされるスパウト２０３と、を備えている。 Example 2
FIG. 3 shows a pouch with a spout according to the second embodiment of the present invention.
This pouch with a spout is housed in a highly rigid exterior container and is fixed to the exterior container 207 with the spout 203, and the volume of the pouch is reduced while being housed in the exterior container 207.
A pouch with a spout is a pouch formed by stacking flexible films, and the pouch body 201 between the film end portions that become the seam is thermally welded and sealed between the film end portions of the pouch body 201. And a spout 203 which is thermally welded together with the film end and sealed.

パウチ本体２０１は、平板状フィルムを折り曲げて、前後一対の平面フィルム２１１，２１１と、平面フィルム２１１，２１１の両側縁間に折り込まれた一対の側面フィルム２１２，２１２とを形成し、平板状フィルムの折り曲げ方向両端部をサイドシール部２１３にて封止して筒状体とし、両端部を側面フィルム２１２，２１２が折り込まれた状態のまま一対の端部シール部２１５，２１５にて封止したガセット袋によって構成され、直方体に開いた形状で使用される。
すなわち、直方体に開いた形状は、スパウト２０３を上に向けた状態で、前後一対の側面部Ａ,Ａと、左右一対の端面部Ｂ，Ｂと、上面部Ｃと、底面部Ｄの６面体で、側面部Ａ，Ａ及び端面部Ｂ、Ｂは、パウチ本体２０１を構成する平面フィルム２１１，２１１を折曲することによって構成され、上面部Ｃと底面部Ｄは側面フィルム２１２，２１２によって構成される。 端部シール部２１５は端面部Ｂ，Ｂの中央に上下方向に延び、サイドシール部２１３は、一方の側面部Ａの上縁に沿って左右両端まで延び、さらに端面部Ｂ，Ｂの上縁に回りこんで端面部Ｂ，Ｂの上縁中央部に位置する端部シール部２１５まで延びている。
減容化する際には、端面部Ｂ，Ｂ、上面部Ｃ及び底面部Ｄが内側に折り込まれ、側面部Ａ，Ａ間の間隔が互いに平行に狭まる方向に収縮する。 The pouch body 201 folds a flat film to form a pair of front and rear flat films 211 and 211 and a pair of side films 212 and 212 folded between both side edges of the flat films 211 and 211. Both ends in the folding direction are sealed with side seals 213 to form a cylindrical body, and both ends are sealed with a pair of end seals 215 and 215 while the side films 212 and 212 are folded. It is composed of gusset bags and is used in a shape that opens in a rectangular parallelepiped.
That is, the shape opened to the rectangular parallelepiped is a hexahedron of a pair of front and rear side surfaces A, A, a pair of left and right end surfaces B, B, a top surface C, and a bottom surface D with the spout 203 facing upward. Thus, the side surface portions A and A and the end surface portions B and B are formed by bending the flat films 211 and 211 constituting the pouch body 201, and the upper surface portion C and the bottom surface portion D are formed by the side surface films 212 and 212. Is done. The end seal portion 215 extends vertically in the center of the end surface portions B and B, the side seal portion 213 extends to the left and right ends along the upper edge of one side surface portion A, and further the upper edge of the end surface portions B and B And extends to the end seal portion 215 located at the center of the upper edge of the end surface portions B and B.
When the volume is reduced, the end surface portions B and B, the upper surface portion C, and the bottom surface portion D are folded inward, and the space between the side surface portions A and A contracts in a direction narrowing in parallel with each other.

サイドシール部２１３は、平面フィルム２１１，２１１と側面フィルム２１２，２１２の一つの角部稜線に沿って設けられ、このサイドシール部２１３にスパウト２０３が熱溶着され、スパウトシール部２０２が構成されている。すなわち、側面部Ａの上側縁の一方の端面部Ｂ側に片寄った位置の平面フィルム２１１と側面フィルム２１２のフィルム端部間にスパウト２０３が差し込まれてフィルムと共に熱溶着されてスパウトシール部２０２が構成されている。スパウトシール部２０２はサイドシール部２１３と連続している。
熱溶着されるスパウト２０３の基部２３１は、図３（Ｃ）に示すように、横断面形状が舟形あるいは紡錘形状で、基部２３１から上方に注出筒２３２が突出している。スパウトシール部２０２についても、スパウト２０３の基部２３１の横断面形状に倣って舟形あるいは紡錘形状となっている。
このスパウト２０３が取り付けられる側面部Ａの外面に応力分散パッチ２０４が貼り付けられている。応力分散パッチ２０４は、実施例１と同様に、スパウトシール部２０２とパウチ本体２０１の内部空間に面する変形自在のフィルム部２０５との境界部２０６を跨いで、スパウトシール部２０２と変形自在のフィルム部２０５の双方を部分的に覆うように貼り付けられる。 The side seal part 213 is provided along one corner ridge line of the flat films 211 and 211 and the side films 212 and 212, and the spout 203 is thermally welded to the side seal part 213 to form the spout seal part 202. Yes. That is, the spout 203 is inserted between the film film end portions of the flat film 211 and the side film 212 at a position offset to one end surface portion B side of the upper edge of the side surface portion A, and the spout seal portion 202 is thermally welded together with the film. It is configured. The spout seal part 202 is continuous with the side seal part 213.
As shown in FIG. 3C, the base portion 231 of the spout 203 to be heat-welded has a cross-sectional shape of a boat shape or a spindle shape, and a dispensing cylinder 232 protrudes upward from the base portion 231. The spout seal portion 202 also has a boat shape or a spindle shape following the cross-sectional shape of the base portion 231 of the spout 203.
A stress distribution patch 204 is attached to the outer surface of the side surface portion A to which the spout 203 is attached. Similar to the first embodiment, the stress distribution patch 204 extends over the boundary portion 206 between the spout seal portion 202 and the deformable film portion 205 facing the internal space of the pouch body 201, and is deformable with the spout seal portion 202. The film portion 205 is pasted so as to partially cover both sides.

実施例１と異なる点は、実施例１では、応力分散パッチ４がパウチ本体１の表裏両面に貼り付けられていたが、この実施例２では、通常の使用状態で上面部Ｃがスパウトシール部２０２に対して直角に開いているので、側面部Ａにのみ貼り付けられている。
また、スパウト２０３がサイドシール部２１３の一端に片寄って取り付けられているので、応力分散パッチ２０４の平面形状は、四半円弧形状の円弧部２４１と、横方向に延びる直線部２４２と、縦方向に延びる直線部２４３で囲まれた扇形状で、横方向直線部２４２がスパウトシール部２０２及びサイドシール部２１３に貼り付けられ、円弧部２４１側の部分が変形自在のフィルム部５に貼り付けられている。また、縦方向直線部２４３は側面部Ａの側縁に沿って配置されている。 The difference from the first embodiment is that, in the first embodiment, the stress distribution patches 4 are attached to both the front and back surfaces of the pouch body 1, but in this second embodiment, the upper surface portion C is a spout seal portion in a normal use state. Since it opens at a right angle to 202, it is attached only to the side surface portion A.
In addition, since the spout 203 is attached to one end of the side seal portion 213, the planar shape of the stress dispersion patch 204 includes a quadrangular arc portion 241, a laterally extending straight portion 242, and a longitudinal direction. In the fan shape surrounded by the extending straight part 243, the horizontal straight part 242 is attached to the spout seal part 202 and the side seal part 213, and the part on the arc part 241 side is attached to the deformable film part 5. Yes. Further, the vertical straight line portion 243 is disposed along the side edge of the side surface portion A.

この応力分散パッチ２０４についても、内容物の熱膨張や落下時の衝撃によりパウチ本体２０１の内圧が上昇してパウチ本体２０１が膨らんでも、応力分散パッチ２０４によってパウチ本体２０１のスパウト２０３の左右エッジ部２０３ａ，２０３ａとスパウトシール部２０２とフィルム部２０５との境界部２０６との交点部Ｐ周辺のフィルム部分２０５の変形が押さえられ、応力が左右エッジ部２０３ａ，２０３ａと境界部２０６の交点部Ｐに集中しないので、エッジ切れを防止できる。
また、応力分散パッチ２０４のフィルム部２０５側の貼り付け部の外周形状が角部の無いなめらかな円弧部２４１となっているので、応力分散パッチ２０４の外周に応力が集中するおそれも無い。
この応力分散パッチ２０４についても、図２（Ｂ），（Ｃ）に示したように、フィルム部２０５に貼り付けられた円弧部２４１に応力が集中しないように、スリットを設けたり、外周に向かって徐々に薄肉として剛性が小さくなる構成することが好ましい。
また、応力分散パッチ２０４を設けることにより適度な剛性が生じるので、減容化による折り畳み時に、側面部Ａが保持され、スパウト付け根部におけるパウチ本体２０１の自己閉塞を防止できる。したがって、従来用いられていた自己閉塞防止具が不要となる。 Also for the stress distribution patch 204, even if the internal pressure of the pouch body 201 rises due to the thermal expansion of the contents or an impact when dropped, the pouch body 201 swells, and the left and right edge portions of the spout 203 of the pouch body 201 by the stress distribution patch 204 203a, 203a, the spout seal portion 202, and the boundary portion 206 between the film portion 205, the deformation of the film portion 205 around the intersection portion P is suppressed, and the stress is applied to the intersection portion P between the left and right edge portions 203a, 203a and the boundary portion 206. Since it does not concentrate, it is possible to prevent edge breakage.
Further, since the outer peripheral shape of the application portion on the film portion 205 side of the stress distribution patch 204 is a smooth arc portion 241 having no corner portions, there is no possibility that stress is concentrated on the outer periphery of the stress distribution patch 204.
As shown in FIGS. 2B and 2C, the stress dispersion patch 204 is also provided with slits or directed toward the outer periphery so that the stress is not concentrated on the arc portion 241 attached to the film portion 205. It is preferable that the thickness is gradually reduced to reduce the rigidity.
In addition, since moderate rigidity is generated by providing the stress distribution patch 204, the side surface portion A is held at the time of folding due to volume reduction, and the self-occlusion of the pouch body 201 at the spout root portion can be prevented. Therefore, the conventionally used self-occlusion prevention tool becomes unnecessary.

応力分散パッチ２０４はパウチ本体２０１の外表面に装着するため、応力分散パウチ２の材質により内容物へ影響を与えることがない。また、応力分散パッチ４の形、色、さらに加飾を施すことにより差別化を図ることもできる。
応力分散パッチの変形例については、実施例１と同様である。
なお、上記各実施例では、パウチ本体の構造としてはガゼット袋タイプのものについて説明したが、ガゼット袋に限定されるものではなく、三方袋、４方袋等の平面構成でもよいし、自立形のスタンディングパウチの構成にも適用可能であり、パウチの構成は問わない。 Since the stress distribution patch 204 is attached to the outer surface of the pouch body 201, the material of the stress distribution pouch 2 does not affect the contents. Differentiation can also be achieved by giving the shape and color of the stress distribution patch 4 and further decoration.
A modification of the stress distribution patch is the same as in the first embodiment.
In each of the above-described embodiments, the structure of the pouch body has been described with respect to the gusset bag type, but is not limited to the gusset bag, and may be a planar configuration such as a three-sided bag, a four-sided bag, or the like. The configuration of the standing pouch is applicable, and the configuration of the pouch is not limited.
