Description

本発明は、フィルムで構成された容器であって、底面に折り込み部を有し、内容物が少なくなっても注出しやすい自立可能な包装容器に関する。   The present invention relates to a self-supporting packaging container that is formed of a film and has a folded portion on the bottom surface and can be easily poured out even when the content is reduced.

ブローボトルのような自立性があり、樹脂使用量が少ないフィルムで構成される自立性容器は、中間フィルムを底側、あるいは側面などに折り込んで設けることにより開発され、簡単な機構を組み込むことによって、製袋機械で生産が可能である。
特に、下側に折り込み部を設けた自立性容器は、自立性も高く、製造し易い上に、内容物を収納前ではコンパクトに畳められることから、ボトル代替用包装体として、積極的に利用されている。
これらは、シャンプーやリンス、液体洗剤などのトイレタリーの詰め替え容器としても用いられると共に、醤油など一次容器としても使用されるようになっている。
A self-supporting container made of a film that is self-supporting like a blow bottle and uses a small amount of resin is developed by folding the intermediate film on the bottom side or side surface, and by incorporating a simple mechanism. It can be produced by a bag making machine.
In particular, a self-supporting container with a folding part on the lower side is highly self-supporting and easy to manufacture, and the contents can be folded compactly before storage. It's being used.
These are used not only as refill containers for toiletries such as shampoos, rinses and liquid detergents, but also as primary containers such as soy sauce.

しかし、表裏一対の外装シートと、両外装シートの下端部から内側に折り込まれてボトムガセット部を形成するボトムガセット容器において、充分に内容物が充填された状態では問題ないものの、内容物を注出して、内容物が少なくなって来た時には、容器全体が折れ曲がり、自立性が損なわれると共に、注ぎ性が悪化する問題があった。
例えば、縦断面が図5−1のように、満充填状態において、容器は表フィルムや裏フィルムに内圧が掛かり、充分に自立することができる。しかし、半分以上排出した場合には、図5−2のように、表フィルムや裏フィルムに対する内圧が低下し、容器の中央部分で折れてしまい、上部が垂れてくる。このように上部が垂れると、下端の底近傍の折り込み部近傍がピンと踏ん張る力が無く、重心が垂れた注出口の方に寄ってしまうので、バランスがとれず、容器が倒れてしまう問題があった。
さらに、自立性が無くなると、注出する為に容器を傾ける時にも、形状を保てず、注出口近傍と共に、底部側も持ち上げなければならず、両手を使用しないと注出しにくいなどの問題も発生する。
However, in a pair of front and back exterior sheets and a bottom gusset container that is folded inward from the lower ends of both exterior sheets to form a bottom gusset part, there is no problem if the contents are sufficiently filled, but the contents are poured. When the contents are reduced and the contents are reduced, the entire container is bent, and there is a problem that the independence is impaired and the pouring property is deteriorated.
For example, as shown in FIG. 5-1, the container can be sufficiently self-supported when the inner film is applied to the front film and the back film when the container is fully filled. However, when discharging more than half, as shown in FIG. 5B, the internal pressure with respect to the front film and the back film is lowered, the container is broken at the center portion, and the upper part is dropped. When the upper part hangs down in this way, the vicinity of the folding part near the bottom of the lower end does not have a force to pinch, and the center of gravity approaches the spout where it hangs down. It was.
In addition, if the independence is lost, when the container is tilted for pouring, the shape cannot be maintained, and the bottom side must be lifted together with the vicinity of the pouring outlet. Also occurs.

このような問題に対し、例えば、特許文献1では、基材とシーラント層を少なくとも有する1枚の積層体を、容器上辺においてシーラント層を内側にして折り曲げて、折り曲げ部と本体表面積層体と本体裏面積層体を形成し、サイドシール部と底シール部によって周縁をシール(融着)してなる詰替え容器であって、前記折り曲げ部の前端は、注出ノズルシール部および抜き加工部シール部と共に、内容物を注出するための注出ノズルを形成しており、該注出ノズルの先端は注出ノズル先端シール部によってシールされており、開封予定線に沿って切り離すことにより注出口を形成するものであり、前記折り曲げ部の後端は、該折り曲げ部と、前記サイドシール部と、これらのそれぞれに交わる気室形成シール部を3辺とする独立気室を形成したことを特徴とする詰替え容器を提案している。さらに、上記詰替え容器において、独立気室として、独立気室内に空気追い出しシール部を設け、空気追い出しシール部によって追い出された空気が溜まった、空気の膨らみを形成したことを特徴とする詰替え容器も提案している。   For such a problem, for example, in Patent Document 1, a laminate having at least a base material and a sealant layer is bent with the sealant layer inside on the upper side of the container, and the bent portion, the main body surface laminate, and the main body are bent. It is a refill container formed by forming a back surface laminate and sealing (fusing) the periphery with a side seal part and a bottom seal part, wherein the front end of the bent part is a dispensing nozzle seal part and a punching part seal part In addition, a pouring nozzle for pouring the contents is formed, and the tip of the pouring nozzle is sealed by the pouring nozzle tip seal portion, and the pouring port is separated by cutting along the planned opening line. The rear end of the bent portion forms an independent air chamber having three sides of the bent portion, the side seal portion, and an air chamber forming seal portion that intersects each of them. It has proposed a refill container, characterized in that was. Further, in the above refilling container, as an independent air chamber, an air expelling seal portion is provided in the independent air chamber, and the air expelled by the air expelling seal portion is accumulated to form an air bulge. A container is also proposed.

しかしながら、この詰め替え容器は、内容物が少なくなって来ると、内容物を収納していた収納部に膨らみが無くなる。この時、上辺の折り曲げ部と、サイドシール部と、これらのそれぞれに交わる気室形成シール部を3辺とする独立気室があっても、底部のある底面近傍まで独立気室が設けられていない。
その為、内容物が少なくなって来ると、詰め替え容器は全体に折れ曲がり、自立性がなくなってしまうという問題があった。
However, when the contents of the refill container are reduced, the storage portion that has stored the contents disappears. At this time, even if there is an independent air chamber having three sides of a bent portion on the upper side, a side seal portion, and an air chamber forming seal portion that intersects each of them, the independent air chamber is provided to the vicinity of the bottom surface with the bottom portion. Absent.
Therefore, when the contents are reduced, there is a problem that the refill container is bent over and loses its independence.

また、特許文献2では、液体、固液混合体、粘体、粉体、粒体、固体などを収納する自立袋であって、該袋が、スタンディングパウチ形式によって形成され、且つ、該袋の胴部を形成する外縁シール部内に、内容物収納部とは別の取っ手機能を有する室が設けられており、
取っ手機能を有する前記室と内容物収納部とは、両者の間の外縁シール部に設けられた開口部を介して連通していて、内容物収納部から開口部を通してこの室に気体を送り込み、開口部をシールすることによりこの室を独立気室とすることができるように構成されていることを特徴とする自立袋を提案している。
Patent Document 2 discloses a self-supporting bag for storing a liquid, a solid-liquid mixture, a viscous body, a powder, a granule, a solid, and the like, the bag being formed in a standing pouch type, and the body of the bag. A chamber having a handle function different from the contents storage portion is provided in the outer edge seal portion forming the portion,
The chamber having a handle function and the content storage portion communicate with each other through an opening provided in an outer edge seal portion between them, and gas is sent from the content storage portion to the chamber through the opening, It proposes a self-supporting bag characterized in that this chamber can be made an independent air chamber by sealing the opening.

この自立袋は、胴部を形成する外縁シール部内に独立気室を設けるので、内容物が少なくなって来ても、自立性は確保し易い。
しかしながら、外縁シール部内に独立気室を設けている。容器から内容物を注出する時、独立気室の周囲をつかんで持ち上げることになる。この時、図4−4に示すように、外縁シール部は表裏二枚のフィルムをシールして形成している為に、フィルム端部600が鋭利で硬い角部を形成していて、この鋭利で固い角部が手に当たり、容器を持ち上げる時に、痛いという問題が発生していた。特に、そのような外縁シール長さ620は、通常、7mm以上のシール部を必要としていたので、硬く、強度も高かくなり、痛かったのである。
さらに、内容物の保護性能を向上させる為に、アルミ箔やエチレン・酢酸ビニル共重合体鹸化物、ポリアミドなどのバリア性を高めるフィルム構成にすることが多い。しかし、バリア性が高いフィルムで容器を製造した場合、フィルム硬度が高まり、外形を切断されたフィルム端部は非常に硬い鋭利な角部を生じる。そのような側面の外縁シール端部は、鋭い鋭利な角部を発生し、手に当たると、特に痛い問題が発生していた。
Since this self-supporting bag is provided with an independent air chamber in the outer edge seal portion that forms the body portion, the self-supporting bag is easy to ensure even if the contents are reduced.
However, an independent air chamber is provided in the outer edge seal portion. When the contents are poured out of the container, it will be lifted by grabbing around the independent air chamber. At this time, as shown in FIG. 4-4, since the outer edge seal portion is formed by sealing the front and back two films, the film end portion 600 forms a sharp and hard corner portion. However, there was a problem that it was painful when the container was lifted by a hard corner hitting the hand. In particular, such an outer edge seal length 620 usually required a seal portion of 7 mm or more, so it was hard, high in strength, and painful.
Furthermore, in order to improve the protection performance of the contents, a film structure that enhances barrier properties such as aluminum foil, saponified ethylene / vinyl acetate copolymer, and polyamide is often used. However, when a container is manufactured with a film having a high barrier property, the film hardness is increased, and the film edge portion whose outer shape has been cut produces sharp and sharp corners. The outer edge seal end portion on such a side surface has a sharp and sharp corner, and a particularly painful problem occurs when it hits the hand.

そこで、内容物の残量が少なくなっても、容器の自立性が損なわれず、かつ、注出する時につかむ独立気室部分が、つかんでも痛くない独立気室を形成してなる自立性フィルム容器を得ることが本発明の課題である。   Therefore, even if the remaining amount of the contents is reduced, the self-supporting film container is formed so that the self-supporting property of the container is not impaired, and the independent air chamber part that is grasped when pouring out forms an independent air chamber that is not painful to grasp. It is an object of the present invention to obtain the above.

The self-supporting film container of the present invention can be self-supporting even when the content is reduced, and the self-supporting container does not break in the middle, so that self-supporting property can be ensured even when it is not used up all at once. In addition, the outer periphery of the independent air chamber that is grasped when the container is poured out does not have a cut end face of a hard and sharp fused film that becomes painful when it is strongly struck. Therefore, the container is very easy to handle.

以下、本発明の自立性容器の実施形態例について、図を用いて詳細に説明する。
図1は本発明の自立性容器の一例で、その外観を示す斜視図である。
フィルム容器のおもて部1と、うら部2との間には、底部側に底面折り込みフィルム3が挟み込まれるように融着している。
この為、底面折り込みフィルム3が広がることによって、底部が形成される。それと共に、底面折り込みフィルム3と表裏フィルムのおもて部1とが重なった底表融着部31と、底面折り込みフィルム3と表裏フィルムのうら部2とが重なって融着された底裏融着部32が、底側に突き出して形成され、安定的な底部になっている。
Hereinafter, embodiments of the self-supporting container of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing an appearance of an example of a self-supporting container according to the present invention.
Between the front part 1 and the back part 2 of the film container, the bottom folded film 3 is fused so as to be sandwiched between the bottom part side.
For this reason, a bottom part is formed when the bottom fold film 3 spreads. At the same time, a bottom front fusion part 31 where the bottom folded film 3 and the front part 1 of the front and back films overlap, and a bottom bottom fusion where the bottom folded film 3 and the back part 2 of the front and back films are fused. The landing part 32 protrudes to the bottom side and forms a stable bottom part.

同時に、上側は、表裏フィルムのおもて部1とうら部2との上面融着部4と、その端部に注出口5が挟むように融着され、上部が形成されている。
この注出口5が融着されている所は、上面と側面との境に面取りをし、その面取りした傾斜部に注出口を融着している。
もちろん、上面の端部や中央に、注出口5を融着してもかまわないが、面取りした上面融着部4と側面融着部6との境に注出口5を設けると、残留する内容物の量を最小にすることができる。
注出口5は、熱可塑性の融着可能な樹脂で成形されていて、かつ、融着部は断面が船形になっていて、融着時に表裏フィルムとの隙間が発生しにくいように形成されている。
At the same time, the upper part is fused so that the upper surface fusion part 4 of the front part 1 and the back part 2 of the front and back films and the spout 5 are sandwiched between the upper part and the upper part is formed.
The place where the spout 5 is fused is chamfered at the boundary between the upper surface and the side surface, and the spout is fused to the chamfered inclined portion.
Of course, the spout 5 may be fused at the end or center of the upper surface, but if the spout 5 is provided at the boundary between the chamfered upper surface fused portion 4 and the side surface fused portion 6, the remaining contents will remain. The amount of objects can be minimized.
The spout 5 is formed of a thermoplastic fusing resin, and the fusing portion has a ship-shaped cross section so that a gap between the front and back films is less likely to occur during fusing. Yes.

さらに、表裏フィルムのおもて部1とうら部2が側面の左右に側面融着部6を形成している。
この側面融着部6の下方は底面折り込みフィルム3に左右とも融着して底面部を形成している。
底面部の左右では、一部底面折り込みフィルム3に穴を開け、表フィルム1と裏フィルム2が直接融着して、底表融着部31と底裏融着部32が繋がるようにすると、より底面部近傍の強度が向上できる。
Further, the front portion 1 and the back portion 2 of the front and back films form side fusion portions 6 on the left and right sides.
Below the side fusion part 6, the left and right sides are fused to the bottom folding film 3 to form a bottom part.
On the left and right sides of the bottom portion, when a part of the bottom folded film 3 is pierced, the front film 1 and the back film 2 are directly fused, and the bottom front fused portion 31 and the bottom back fused portion 32 are connected. The strength near the bottom can be improved.

さらに、注出口5が融着されていない側面融着部6は、表裏フィルムがおもて部1とうら部2に折り返し部12で折り返されていて、上面側と底面側の間に、独立気室61を形成し、内部に空気などの気体を注入している。この独立気室61の太さは、直径が10mm〜50mmが適当である。
10mm以下の場合、容器の自立性が小さくなって、内容物が少なくなって来ると、自立できなくなってしまう。
また、50mm以上になると、独立気室61をつかんで容器を傾け、注出する場合、大きすぎて、つかみにくい問題が発生するので、独立気室61の太さは、直径が10mm〜5
0mmが良い。
また、独立気室61は、底面折り込みフィルムの融着上端位置から、上面折り込みフィルムの融着下端位置との間に、気体を封じた中空部を設けている。
独立気室61の下端を底面折り込みフィルムの融着上端位置より低い位置まで設けると、折り込みフィルムの融着が非常に難しくなり、落下強度や耐荷重強度に問題が発生し易い。
逆に、独立気室61の下端を底面折り込みフィルムの融着上端位置よりかなり高い位置にしてしまうと、自立性が低下し、内容物が少なくなると、倒れてしまいやすい。
独立気室61の上端は、上面折り込みフィルムの融着下端位置近傍にする。できるだけ、高い位置にすることによって、内容物が少なくなっても、注出口5の重みで、容器が折れて、その荷重で倒れにくくする。
Further, in the side surface fusion part 6 where the spout 5 is not fused, the front and back films are folded back to the front part 1 and the back part 2 by the folded part 12, and are independent between the upper surface side and the bottom surface side. An air chamber 61 is formed, and a gas such as air is injected therein. The thickness of the independent air chamber 61 is suitably 10 mm to 50 mm in diameter.
In the case of 10 mm or less, when the self-supporting property of the container becomes small and the content becomes small, it becomes impossible to self-support.
In addition, if the container is tilted and poured out by grabbing the independent air chamber 61 when it is 50 mm or more, the problem is that the size of the independent air chamber 61 is 10 mm to 5 mm.
0 mm is good.
Further, the independent air chamber 61 is provided with a hollow portion sealed with gas between the fusion upper end position of the bottom folded film and the fusion lower end position of the top folded film.
If the lower end of the independent air chamber 61 is provided at a position lower than the fusion upper end position of the bottom folded film, it becomes very difficult to fuse the folded film, and problems with drop strength and load bearing strength are likely to occur.
On the contrary, if the lower end of the independent air chamber 61 is set to a position considerably higher than the fusion upper end position of the bottom folded film, the self-supporting property is lowered, and if the contents are reduced, the independent air chamber 61 tends to fall down.
The upper end of the independent air chamber 61 is set near the fusion lower end position of the top folded film. By setting the position as high as possible, even if the contents are reduced, the container is broken by the weight of the spout 5 and is not easily collapsed by the load.

図2は、本発明の自立性容器で、図1のA面における縦断面図である。
表裏フィルムのおもて部1とうら部2が底部側は底面折り込みフィルム3を介在して融着され、底面折り込みフィルム3が前後に広がり、安定した底面部を形成している。
また、上面融着部4と側面融着部6とが交差する端部近傍には、おもて部1とうら部2のフィルム間に注出部5が入って融着されている。
FIG. 2 is a self-supporting container according to the present invention, and is a vertical cross-sectional view of the A plane of FIG.
The front part 1 and the back part 2 of the front and back films are fused on the bottom side with a bottom folded film 3 interposed therebetween, and the bottom folded film 3 spreads back and forth to form a stable bottom part.
Further, in the vicinity of the end portion where the upper surface fusion portion 4 and the side surface fusion portion 6 intersect, the pouring portion 5 is inserted and fused between the films of the front portion 1 and the back portion 2.

図3は、本発明の自立性容器で、それぞれ、図2のaから見た平面図と、b,c,dで切断した横断面図である。
図3−1は注出口を設けた上面部の上方におけるaの上方から見た平面図で、表裏フィルムのおもて部1とうら部2とのシール部の右端部に注出口5を融着している。
FIG. 3 is a plan view seen from a in FIG. 2 and a cross-sectional view cut along b, c and d, respectively, in the self-supporting container of the present invention.
FIG. 3A is a plan view of the upper surface portion where the spout is provided, as viewed from above a. In FIG. I wear it.

図3−2は、bで切断した容器の胴部断面図で、表裏フィルムのおもて部1とうら部2とが左右に側面融着部6を形成し、内容物が入る胴部を形成していて、かつ、左の側面融着部6の中央に独立気室61を設けている。
独立気室61のある側面融着部6端部が、表裏フィルムを折り曲げて形成されているので、先端は丸くなっている。
この独立気室61には空気を充填しているが、窒素ガスやヘリウムガスなど、他の気体であってもかまわない。もちろん、水のような液体でもかまわないが、重くなると、内容物が減少した時に、倒れ易い問題が発生し易いので、気体が好ましい。
FIG. 3-2 is a cross-sectional view of the body section of the container cut at b. An independent air chamber 61 is provided at the center of the left side fusion part 6.
Since the end of the side fusion part 6 with the independent air chamber 61 is formed by bending the front and back films, the tip is rounded.
The independent air chamber 61 is filled with air, but other gases such as nitrogen gas and helium gas may be used. Of course, a liquid such as water may be used, but if it becomes heavier, a problem is likely to occur when the contents are reduced, so gas is preferred.

図3−3は、cで切断した容器の底部近傍の胴部断面図である。
折り込みフィルムは、折り込んで合わさる内層表面は2軸延伸されたポリエチレンテレフタレートフィルムや2軸延伸ポリプロピレンフィルムなどを用い、融着しにくいフィルムにしておく。
そして、表裏フィルムに合う面には低密度ポリエチレンなどの融着性の高い材料を外層に使用している。
その為、折り込みフィルムを挟んで表裏フィルムのおもて部1とうら部2を融着すると、折り込まれた折り込みフィルムの内面同士は融着せず、折り込みフィルムの外側の融着性の高い外層とおもて部1やうら部2との間だけが融着する。
そして、折り込みフィルムがない左右端部では、直接、おもて部1とうら部2が融着している。
これらのフィルムは、通常のドライラミネーション機、エクストルーダーラミネート機などを使用して、貼り合わせることにより製造することができる。
また、折り込みフィルムにおいて、左右の一部に折り込みフィルム穴を開け、部分的に表フィルム1と裏フィルム2を融着して、底表融着部31と底裏融着部32が直接融着するようにしても良い。
FIG. 3-3 is a cross-sectional view of the trunk portion near the bottom of the container cut at c.
The folded film is made of a film that is difficult to fuse by using a biaxially stretched polyethylene terephthalate film, a biaxially stretched polypropylene film, or the like on the inner layer surface to be folded.
And the material which has high meltability, such as low density polyethylene, is used for the outer layer on the surface which matches the front and back films.
Therefore, when the front part 1 and the back part 2 of the front and back films are fused with the folded film interposed therebetween, the inner surfaces of the folded folded film do not fuse with each other, and the outer layer having a high fusibility between the folded film and the outer layer is formed. Only the front part 1 and the back part 2 are fused.
The front portion 1 and the back portion 2 are fused directly at the left and right end portions where there is no folded film.
These films can be produced by pasting together using an ordinary dry lamination machine, an extruder laminating machine or the like.
Also, in the fold film, fold film holes are made in the left and right parts, the front film 1 and the back film 2 are partially fused, and the bottom surface fused part 31 and the bottom back fused part 32 are directly fused You may make it do.

図3−4は、dで切断された容器の底融着部の断面図である。
底面折り込みフィルム3と表裏フィルムのおもて部1との底表融着部31や、底面折り込みフィルム3と表裏フィルムのうら部2との底裏融着部32と、底面折り込みフィルム3のない左右の側面融着部6で構成されて、それらが繋がっている。
繋がっていて、かつ、厚みもあるので、強度の高い底面を形成している。
FIG. 3-4 is a cross-sectional view of the bottom fusion part of the container cut at d.
There is no bottom surface fusion part 31 between the bottom folded film 3 and the front part 1 of the front and back film, no bottom fused part 32 between the bottom folded film 3 and the back part 2 of the front and back film, and no bottom folded film 3 The left and right side fusion parts 6 are connected to each other.
Since it is connected and thick, it forms a strong bottom surface.

図4−1は、本発明の一例で、表裏フィルムのおもて部1とうら部2を融着して独立気室61を形成しているが、独立気室61のある側面融着端部60が、折り返し部12になっていて、表裏フィルムを折り曲げて形成されているので、先端は丸くなっていて、強く手でつかんでも痛くない。
FIG. 4 is an enlarged cross-sectional view of the vicinity of the independent air chamber in the cross section of the container cut in FIG.
FIG. 4A is an example of the present invention, and the front and back films of the front part 1 and the back part 2 are fused to form the independent air chamber 61. Since the portion 60 is the folded portion 12 and is formed by folding the front and back films, the tip is rounded and does not hurt even if it is strongly held by the hand.

図4−2は、本発明の他の一例で、表裏フィルムのおもて部1とうら部2を融着して独立気室61を形成しているが、独立気室61を設けた側面シール部の独立気室外側端部は、表裏フィルムのシールが無く、折り返しだけで独立気室を形成しているので、痛くなる融着部が無く、つかみやすい。   FIG. 4-2 is another example of the present invention, and the independent air chamber 61 is formed by fusing the front portion 1 and the back portion 2 of the front and back films, but the side surface on which the independent air chamber 61 is provided. Since the independent air chamber outer end portion of the seal portion does not have the seal of the front and back films and forms the independent air chamber only by folding, there is no fused portion that hurts and it is easy to grasp.

図4−3は、本発明の別の一例で、表裏フィルムのおもて部1とうら部2を融着して独立気室61を形成しているが、独立気室を設けた側面端部シール幅621が狭く、外側の端部には、表裏フィルムの未シール部63が形成されている。
未シール部63は、あくまでシールが無く、表裏フィルムが折り返しているだけになり、独立気室61から離れて形成されているので、側面端部は柔らかく、丸みも帯びている。その為、独立気室61全体を強くつかんでも全く痛くない。
FIG. 4-3 is another example of the present invention, in which the front part 1 and the back part 2 of the front and back films are fused to form the independent air chamber 61, but the side end provided with the independent air chamber The part seal width 621 is narrow, and an unsealed part 63 of the front and back films is formed at the outer end part.
