Self-supporting packaging bags are increasingly used for refilling liquid contents such as body soaps, liquid detergents and toiletries represented by softeners into plastic containers that are used repeatedly.

この自立性包装袋では、底が船底型にシールされたスタンディングパウチ形式のものが一般的に用いられている。このような自立性包装袋でも用いる包装材料の腰が不足すると、商品陳列時に自立性が不足したりする恐れがあり、更に検討の余地があった。   In this self-supporting packaging bag, a standing pouch type whose bottom is sealed in a ship bottom type is generally used. If the packaging material used in such a self-supporting packaging bag is insufficient, the self-supporting property may be insufficient at the time of product display, and there is room for further study.

そのため、例えば、スタンディングパウチ形式によって形成され、且つ、袋の胴部及び底部を形成する周縁シール部内、または周縁シール部以外の内容物収納部に隣接する場所に意図的に設けられたシール部に、内容物収納部とは異なる、片方のサイドシール部から注出口先端近傍に至る位置まで内容物の注出経路に沿う形で設けたサイドシール部と、もう一方のサイドシール部及び底部が連通した独立充填室が設けられている自立性包装袋がある(特許文献1)。   Therefore, for example, a seal part formed by a standing pouch type and intentionally provided in a peripheral seal part that forms the body part and bottom part of the bag or in a place adjacent to a content storage part other than the peripheral seal part. Different from the contents storage part, the side seal part provided along the content extraction path from one side seal part to the position near the tip of the spout, and the other side seal part and bottom part communicate with each other There is a self-supporting packaging bag provided with an independent filling chamber (Patent Document 1).

しかし、この自立性包装袋においては、底部の周縁シール部が独立充填室により膨らんでいるため、二つ折りして底部に挟み込んだ底部材が広がることができずに、自立性が損なわれる恐れがある。   However, in this self-supporting packaging bag, since the peripheral seal portion of the bottom portion is inflated by the independent filling chamber, the bottom member folded in half and sandwiched between the bottom portions cannot spread, and the self-supporting property may be impaired. is there.

公知文献を以下に示す。   Known documents are shown below.

Hereinafter, embodiments for carrying out the present invention will be described.
FIG. 1 is an explanatory view schematically showing an example of the self-supporting packaging bag of the present invention on the front side. FIG. 2 is an explanatory view schematically showing a state where the independent filling chamber is inflated in an example of the self-supporting packaging bag of the present invention, in the XX section of FIG. 1. FIG. 3 is an explanatory view schematically showing the shape of the independent filling chamber of the bottom member of another example of the self-supporting packaging bag of the present invention.

本例の自立性包装袋100は、図1の正面図、図2の断面図に示すように、重ね合わせた表フィルム1と裏フィルム2の下端に、二つ折りした底部材3が、折り部を上にして挟み込まれ、周縁部がシールされている。   As shown in the front view of FIG. 1 and the cross-sectional view of FIG. 2, the self-supporting packaging bag 100 of the present example has a folded bottom member 3 at the lower end of the superposed front film 1 and back film 2. The peripheral part is sealed.

本例の自立性包装袋100は、底部材3を挿入した底部が、周縁部が船底型にシールされていて、船底型シール部4になっていて、スタンディングパウチ形式になっている。尚、二つ折りした底部材3の両端には、切り欠き部5が設けられていて、この切り欠き部5で表フィルム1と裏フィルム2が互いにシールされていて、底部の両端が開かないようになっている。   In the self-supporting packaging bag 100 of this example, the bottom part into which the bottom member 3 is inserted is sealed at the periphery with a ship bottom mold, and is a ship bottom mold seal part 4, which is in a standing pouch form. In addition, the notch part 5 is provided in the both ends of the bottom member 3 folded in half, and the front film 1 and the back film 2 are mutually sealed by this notch part 5, and the both ends of a bottom part are not opened. It has become.

底部材3は、少なくとも外面側フィルム3aと内面側フィルム3bからなる積層フィルムからなっていて、自立性包装袋100の底になる位置に未積層部が設けられていて、この未積層部の層間に内容物収納部とは別の独立充填室6が設けられている。本例では独立充填室6は、底部材3の周縁シールを除いた部分の略全面に設けられている。   The bottom member 3 is composed of a laminated film composed of at least an outer surface side film 3a and an inner surface side film 3b, and a non-laminated portion is provided at a position that becomes the bottom of the self-supporting packaging bag 100. In addition, an independent filling chamber 6 separate from the contents storage portion is provided. In this example, the independent filling chamber 6 is provided on substantially the entire surface of the bottom member 3 excluding the peripheral seal.

本例では、独立充填室6を底部材3の周縁シールを除いた部分の略全面に設けたが、必ずしも全面に設けなくとも、底部材3の周縁シールを除いた部分に設ければ良い。例えば、図3の底部材31のように、底部材31の周縁シールを除いた部分に底部材31の広がる方向に、細長い複数の棒状とそれらをつなぐ直交方向の棒状を組み合わせて形状にしても良い。   In this example, the independent filling chamber 6 is provided on substantially the entire surface of the bottom member 3 excluding the peripheral seal. However, the independent filling chamber 6 may be provided on the entire surface of the bottom member 3 excluding the peripheral seal. For example, like the bottom member 31 in FIG. 3, the bottom member 31 is formed by combining a plurality of elongated rods and orthogonal rods connecting them in the direction in which the bottom member 31 extends in a portion excluding the peripheral seal. good.

また、船底型シール部4には、独立充填室6に連通する連絡路7と、連絡路7を外部と連絡させ、独立充填室6に充填物を充填するための充填口8が設けられている。連絡路7は、独立充填室6と同様に未積層部でなっている。また、充填口8は、独立充填室6に充填物を充填後、接着剤やシーラント層を設けた封止ラベルを貼着して封止してもよい。   Further, the ship bottom type seal portion 4 is provided with a communication path 7 communicating with the independent filling chamber 6 and a filling port 8 for connecting the communication path 7 to the outside and filling the independent filling chamber 6 with a filling material. Yes. Similarly to the independent filling chamber 6, the communication path 7 is a non-laminated portion. The filling port 8 may be sealed by sticking a sealing label provided with an adhesive or a sealant layer after filling the independent filling chamber 6 with a filling material.

このようにして、独立充填室6に充填物を充填して膨らませることにより、二つ折りされていた底部材3が開いて、自立性包装袋100の底を形成し、自立性を確保することができる。   In this way, by filling and filling the independent filling chamber 6 with the filler, the bottom member 3 folded in half is opened to form the bottom of the self-supporting packaging bag 100 to ensure self-supporting.

Moreover, liquids, such as water and oil, can be used. Furthermore, solids such as inorganic powder and foamed resin can be filled together with these.

特に独立充填室6に気体を充填しておくと、内容物が液体で落下などの衝撃を受けた場合に、衝撃により発生した圧力が液体では、そのまま全方向に向かうが、独立充填室6に充填された気体が、体積変化して圧力を緩和することができる。そのため、落下などの衝撃に対しての耐性が向上する。   In particular, when the independent filling chamber 6 is filled with a gas, when the contents are impacted by a drop such as liquid, the pressure generated by the impact is directed in all directions as it is in the liquid. The filled gas can change its volume to relieve pressure. Therefore, resistance to impacts such as dropping is improved.

周縁部のシールのうちサイドシール部9には、自立性包装袋100を開封するためのノッチ10を設けている。ノッチ10は本例では一方のサイドシール部9に設けているが、左右両方のサイドシール部9、9に設けても良い。また、開封するためのハーフカット線を一方のサイドシール部から他方のサイドシール部の両端まで設けても良い。   The side seal portion 9 of the peripheral portion seals is provided with a notch 10 for opening the self-supporting packaging bag 100. The notch 10 is provided in one side seal portion 9 in this example, but may be provided in both the left and right side seal portions 9 and 9. Moreover, you may provide the half cut line for opening from one side seal part to the both ends of the other side seal part.

船底型シール部4にも、独立充填室6を切断し、開放するためのノッチ11が設けられている。本例では、ノッチを設けているが、ハーフカット線などの他の易切断機構を設けても良い。これにより、使用済みの自立性包装袋100を廃棄するときに、独立充填室をつぶすことができ、減容化させて、自立性包装袋100を廃棄することができる。   The ship bottom type seal portion 4 is also provided with a notch 11 for cutting and opening the independent filling chamber 6. In this example, a notch is provided, but other easy cutting mechanisms such as a half-cut line may be provided. Thereby, when discarding the used self-supporting packaging bag 100, the independent filling chamber can be crushed, the volume can be reduced, and the self-supporting packaging bag 100 can be discarded.
