【発明の属する技術分野】
本発明は、スナック菓子類、チョコレート、ケーキ菓子等の壊れやすく、しかもバラで収納される包装袋に関し、詳しくは開封時に内容物を破損させずに、かつ開口部を大きく開けることが可能で、内容物が取り出し易い開封容易な包装体に関するものである。
【0002】
【従来の技術】
従来より、スナック菓子類やチョコレート、或いはケーキ状の菓子等の壊れやすい内容物をバラで収納する包装袋や、この包装袋と外箱の組合せによる包装体がよく知られている。
例えば、図4(A)に示すような、ピロー袋が知られており、その開封は天地のシール部t,t又は背シールhを左右に引っ張るように開封するもの、或いは図4(B)に示すように、シール部tにノッチnを設けこの部分から切り裂き開封するようにしたものがある。
また、図5に示すように、外箱30に入ったアルミニウム蒸着フィルム等による内袋33を背シールのノッチnから開封するようにしたものがある。
さらには、図示はしないが、ピロー袋の包装材料の表面に全面傷加工を施し、任意の箇所から開封することができるようにした包装体が知られている。
【0003】
しかしながら、前述したピロー袋等の包装袋の場合には、流通過程、或いは開封時に袋を押さえることになり内容物が壊れやすい。また、外箱入りの場合、外箱の開封とともに内袋の開封が必要となり、内容物の取り出しが複雑となり、しかも製造コストが高くなる。さらに任意の箇所から開封可能とした包装体の場合には、開封口が様々な形状となり、開封口の形状により内容物の取り出しが不便となる場合があり、さらに開封時の押圧により内容物が壊れるといった問題があった。
【0004】
【発明が解決しようとする課題】
そこで本発明は、上記問題に鑑みなされたもので、その目的とするところは、内容物を保護することができ、しかも弱い力でも容易に開封することができる包装体であって、その際、内容物を壊すことがなく、かつ開封口を大きくし内容物の取り出しが容易となる開封容易な包装体を提供することにある。
【0005】
【課題を解決するための手段】
本発明に於いて上記目的を達成するために、請求項1の発明では、樹脂フィルム11の両側部a,aの内側に、該樹脂フィルム11の上下端部に達しない長さのバリア性を有する側板12,12を縦方向に貼着し、該樹脂フィルム11の中央部には前記側板に対して直交する方向に蓋板14を設けてなり、前記樹脂フィルム11を側板12,12の両側に沿って折り曲げて、中央近傍で両端部のシール部t,tを合わせて背シールhを施し、さらに内容物を充填した後、上下の端部p,pを接着又は融着してなる包装袋であって、前記側板12の中央部で、かつ樹脂フィルム11のいずれか一方の側板12下に、該側板12に対して直交する方向に半円形状の切り欠きkによる開封片15を側板12の範囲内に設けたことを特徴とする開封容易な包装体である。
【0006】
請求項2の発明では、請求項1に記載の開封容易な包装体において、
少なくとも開封片15側の前記側板12シーラントの内面側に、ガスバリア性フィルムが位置することを特徴とする。
【0007】
請求項3の発明では、請求項1又は請求項2に記載の開封容器な包装体において、少なくと開封片15側の前記側板12シーラントにイージーピールフィルムを用いたことを特徴とする。
請求項4の発明では、請求項1、2又は請求項3に記載の開封容器な包装体において、樹脂フィルム11への側板12,12の縦方向への貼着は、側板の周辺を部分貼着してなることを特徴とする。
【0008】
【発明の実施の形態】
本発明の開封容易な包装体は、アルミニウム、アルミナ、酸化ケイ素等の金属蒸着を施した樹脂フィルム11の両側部a,aの内側に、樹脂フィルムの上下端部に達しない長さの側板12,12を縦方向に部分貼着すると共に、この樹脂フィルム11の中央部には、側板12,12に対して直交する方向(横方向)に前記側板と同構成の蓋板14を設けたもので、この組立ては、樹脂フィルム11を側板12,12の両側に沿って内側に折り曲げ、中央近傍でフィルム両端のシール部t,tを合わせて背シールを施し、さらに内容物を充填した後、フィルムの上下端部p,pを接着又は融着した包装袋である。この際、包装袋には予めいずれか一方の側板12中央部で、かつ樹脂フィルム11の一方の側板12下に、この側板12に対して直交する方向に半円形の切り欠きkによる開封片15を設けたもので、この開封片を摘み包装袋の上面部分を横方向に引き裂き、開封するものである。
【0009】
図に基づきさらに本発明の実施例を説明する。
図1は、本発明の開封容易な包装体の展開図であり、図2(A)は、組み立てた包装体の一例を示す斜視図であり、(B)は、開封片から引き裂き開封した状態を示す斜視図である。
図中11はアルミニウム等の金属蒸着が施された樹脂フィルム、12は台紙である側板を示し、14は同様に蓋板、15は開封片、tは樹脂フィルムの両側部のシール部、pは同じく上下端部の接着又は融着部分を示す。
【0010】
本発明で用いる樹脂フィルム11の積層構成例を示すと、例えば、
・二軸延伸ポリプロピレン20μm(HSOPP)/アルミ蒸着未延伸ポリプロピレン25μm(VMCPP)であり、
・HSOPP20μm/横一軸高密度ポリエチレン(HDPE)18μm(例えば、カラリヤンY、東洋化学株式会社製)/VMCPP25μmであり、
・ポリエチレンテレフタレート12μm(PET)/アルミニウム箔7μm/CPP25μmであり、
・酸化ケイ素蒸着ポリエステル12μm(GLPET)/CPP25μmである。
以上に示すように、いずれもドライラミネーションにより積層し包装材料としたもので、表面の印刷適性、横裂き性、バリヤ性等の目的に応じて適宜な積層構成のフィルムを用いることができる。
【0011】
また、台紙である側板12及び蓋板14の構成例として、バリヤ性を必要とする場合には、
・PET12μm/ポリエチレン15μm(SPE)/紙190g/ m2 /SPE15μm/酸化ケイ素蒸着ポリエステル12μm(GLPET)/イージーピールポリプロピレン25μm(PP)である。
これに対し防湿性のみの場合には、
・ポリプロピレンシート300μm/イージーピールポリプロピレン25μm(PP)構成の台紙が使用できる。
【0012】
上記構成のフィルム及び台紙を適宜選択し本発明の包装体を作製するもので、図1に示すように、樹脂フィルム11の一方の側部aの内側中央部に、半円形状の切り欠きkによる開封片15を形成し、このフィルム11の両側部a,a内側に折り部e,e,e,eを介して側板12,12を部分貼着したものである。この部分貼着は、側板12,12の周囲を接着又は融着により貼着し、側板の中央部は貼着しない。この際、側板12,12はフィルム11の上下端部p,pに達しない長さとする。また、一方の側板12の下側中央部分に切り欠きkによる開封片15が位置するように側板12を部分的に貼り付ける。
さらに側板12,12に挟まれた樹脂フィルム11の中央部には、側板に対して直交する方向(横方向)に蓋板14を貼り付ける。この蓋板14は、図1に示すように、開封片15の幅より僅かに内側に位置するように短い寸法としたものである。
なお、開封片15を形成する切り欠きkは、側板12の範囲内とする。この範囲を越えて設けると、内容物が直接外部と接触し問題となる。また包装体をガスバリア性を有するフィルムで構成しても、この部分から外気と通じてしまい、包装体にガスバリア性がなくなる。
【0013】
この包装材料の組立ては、シートを流れ方向に進めて側板12,12の両側に沿って折り部e,e,e,eから内側に折り曲げ、フィルム11両側端のシール部t,tを中央部近傍で合わせて融着による背シールhを施す。さらに上方又は下方よりスナック菓子類、クッキー等の内容物を充填した後、フィルム上下の端部p,pを接着又は融着することにより内容物が密封された包装体が得られる(図2(A)を参照)。
【0014】
なお、本発明の包装体の作製をシート状の樹脂フィルム11により説明したが、実作業工程においては、図示はしないが、ロール状のフィルムを送り出し、切り欠きkの形成、側板12,12、蓋板14の台紙の貼着、背シールh、内容物の充填、天地のシールと切断工程を連続して行い製造することができる。
【0015】
この包装体の開封は、図2(B)に示すように、貼着されていない開封片15を摘み上方に引き上げ包装体の上面を反対側に引っ張ると、包装材が引き裂かれ開封することができる。
【0016】
本発明の包装体における開封片15は適宜な形状とすることができるが、図3に示すように、好ましくは切り欠きkによる半円形状の開封片とすることにより、摘み易く、しかも開封し易くなる。またこの開封片の幅を広くすることにより開口部を大きくすることができる。
【0017】
また、本発明の包装体における特徴は、図4の概略図に示すように、側板12,12を樹脂フィルム11に全面貼着するものではなく、側板の周辺12aを部分貼着し、その中央部分12bは貼着しないほうが良い。
これにより開封片15の先端部分は貼着されずに、基部が貼着された状態となる。従って、開封する際は開封片を摘み易く、基部が貼着されていても側板12のシーラントとしてのイージーピールフィルムにより剥離することが容易で、開封片15を引き上げるだけで剥離し、さらに反対側に引っ張ることにより、開封片15の幅寸法で包装体の上面を蓋板14に沿って引き裂くことができる。
【0018】
【発明の効果】
本発明は以上の構成であるから、下記に示す如き効果がある。
すなわち、本発明の包装体は開封片の大きさを変えることで、開封口の大きさを広くすることも、又狭くすることも可能で、さらには形状も変化させることができる。
また開封性は、台紙のシーラントにイージーピールフィルムを使用しているので容易に開封することができ、また横一軸高密度ポリエチレンフィルムが積層されているので、包装材の引き裂きも子供の弱い力で簡単に行える。
さらにガラス蒸着フィルムを使用した包装材料によりバリヤ性を保持することが容易となる。
【0019】
さらに加えて、従来の包装体の製造と同様の製造工程により作製することができるので、内容物の自動充填、連続製造が可能となるので、包装材料、製造コストを低く抑えることができる。

As described above, all of them are laminated by dry lamination to form a packaging material, and a film having an appropriate laminated structure can be used according to purposes such as surface printability, lateral tearability, and barrier properties.
[0011]
In addition, as a configuration example of the side plate 12 and the cover plate 14 that are mounts, when barrier properties are required,
PET 12 μm / polyethylene 15 μm (SPE) / paper 190 g / m 2 / SPE 15 μm / silicon oxide-deposited polyester 12 μm (GLPET) / easy peel polypropylene 25 μm (PP).
On the other hand, if only moisture-proof,
-A mount of polypropylene sheet 300 μm / easy peel polypropylene 25 μm (PP) can be used.
[0012]
A film and mount having the above-described structure is appropriately selected to produce the package of the present invention. As shown in FIG. 1, a semicircular cutout k is formed at the inner central portion of one side portion a of the resin film 11. Is formed, and side plates 12 and 12 are partially attached to both sides a and a of the film 11 via folding parts e, e, e, and e. In this partial attachment, the periphery of the side plates 12 and 12 is attached by adhesion or fusion, and the central portion of the side plate is not attached. At this time, the side plates 12 and 12 have a length that does not reach the upper and lower ends p and p of the film 11. Further, the side plate 12 is partially affixed so that the opening piece 15 by the notch k is positioned at the lower center portion of the one side plate 12.
Further, a lid plate 14 is attached to the central portion of the resin film 11 sandwiched between the side plates 12 and 12 in a direction (lateral direction) orthogonal to the side plates. As shown in FIG. 1, the cover plate 14 has a short dimension so as to be located slightly inside the width of the opening piece 15.
The notch k forming the opening piece 15 is within the range of the side plate 12. If the content exceeds this range, the contents directly come into contact with the outside, causing a problem. Further, even if the package is formed of a film having a gas barrier property, it is communicated with the outside air from this portion, and the gas barrier property of the package is lost.
[0013]
This packaging material is assembled by advancing the sheet in the flow direction and bending it inward from the folded portions e, e, e, e along both sides of the side plates 12, 12, and sealing portions t, t on both sides of the film 11 at the center. A back seal h by fusion is applied in the vicinity.

[0015]
As shown in FIG. 2 (B), the package can be opened by picking the unsealed unsealed piece 15 and pulling it upward and pulling the upper surface of the package to the opposite side. it can.
[0016]
The opening piece 15 in the package of the present invention can have an appropriate shape. However, as shown in FIG. 3, it is preferable to use a semicircular opening piece with a notch k so that it can be easily picked and opened. It becomes easy. The opening can be enlarged by increasing the width of the opening piece.
[0017]
In addition, as shown in the schematic diagram of FIG. 4, the feature of the package of the present invention is that the side plates 12 and 12 are not adhered to the resin film 11 as a whole, but the periphery 12a of the side plate is partially adhered, and the center It is better not to stick the part 12b.
Thereby, the front-end | tip part of the opening piece 15 will not be stuck, but will be in the state to which the base was stuck. Therefore, when opening, it is easy to pick the opening piece, and even if the base is stuck, it is easy to peel off with an easy peel film as the sealant of the side plate 12, peeling by simply pulling up the opening piece 15, and the other side By pulling to the top, the upper surface of the package can be torn along the cover plate 14 with the width dimension of the opening piece 15.
[0018]
【The invention's effect】
