Description

本発明は、包装体の開口部を開閉自在とし、かつ開口形状を維持することが可能なジッパを形成した、開口保形機能を有するジッパ付き包装体に関する。   The present invention relates to a package with a zipper having an opening retaining function, in which a zipper capable of opening and closing the opening of the package and maintaining the opening shape is formed.

従来、粉体、固体のみならず液体、流動食等の内容物を密封包装した包装体（パウチ）の開口部分を開閉封自在に形成されたジッパを有するジッパ付き包装体が知られている（例えば、特許文献１）。
このジッパは、直線状の凹部と対向する直線状の凸部とがそれぞれ凹凸嵌合することにより、前記開口部を水平に開閉封自在な構成としている。特に、包装体の開口部にジッパを形成することにより、別部材からなるキャップ等を用いることなく、開口部が平面形状を維持しつつ開口部の密閉若しくは開封が可能となる。 2. Description of the Related Art Conventionally, a package with a zipper having a zipper in which an opening portion of a package (pouch) in which contents such as powder and solid as well as liquid and liquid food are hermetically packaged is freely opened and closed is known ( For example, Patent Document 1).
The zipper has a configuration in which the opening is horizontally openable and closable by fitting the linear concave portion and the linear convex portion facing each other into an irregular shape. In particular, by forming a zipper at the opening of the package, it is possible to seal or open the opening while maintaining the planar shape of the opening without using a cap made of another member.

このような、ジッパ付き包装体においては、パウチの開口部は、積層フィルム等の柔軟性のある材料であるため、ジッパを開封後においても、開口部の開口形状が安定しないという問題があった。さらには、開口部を開封した後、内容物を取り出す際において、フィルムに比べ剛性の高いジッパにより、開口が直ちに閉じてしまうという問題がある。よって、常に、開口部を手で補助して開口形状を維持する必要があり、内容物の取り出しに手間がかかるという問題があった。   In such a package with a zipper, since the opening of the pouch is a flexible material such as a laminated film, there is a problem that the opening shape of the opening is not stable even after the zipper is opened. . Furthermore, when the contents are taken out after opening the opening, there is a problem that the opening is immediately closed by a zipper having a higher rigidity than the film. Therefore, it is always necessary to assist the opening with the hand to maintain the opening shape, and there is a problem that it takes time to take out the contents.

また、ジッパ付き包装体においては、初期開封時において、包装体の上方部分のフィルムを、ノッチ等を起点として水平方向に切除することにより初期開封を行なうが、切除部分のフィルムがくっつきやすく、開口部分を閉塞してしまい、ジッパ上方フィルムの開封操作が困難であった。   In addition, in the package with a zipper, at the time of initial opening, the film in the upper part of the package is opened in the horizontal direction starting from a notch or the like, but the film in the cut part is easy to stick. The portion was blocked, and the opening operation of the zipper upper film was difficult.

特に、初期開封時に、ジッパ上方のフィルムを、はさみ、包丁またはナイフなどの鋭利な道具を用いて切除すると、さらにジッパ上方の前後のフィルムがくっつきやすく、これらのフィルムを引き離すために、切除部分のフィルムを注視して指先で慎重に、引き離す必要があった。よって、お年寄りや、子供にとっては、困難な作業を伴うものである。   In particular, when the film above the zipper is cut with a sharp tool such as scissors, a knife or a knife at the time of initial opening, the front and rear films above the zipper are more likely to stick together, and in order to separate these films, It was necessary to watch the film and carefully pull it away with the fingertips. Therefore, it is a difficult task for the elderly and children.

Opening 11 is formed. Further below the opening 11 after the initial opening, the zipper 3 is concavo-convexly fitted and hermetically seals the accommodating portion 2, and the zipper 3 is opened by separating the front and rear films 8 above the zipper, thereby opening the accommodating portion. 2 contents can be taken out.

次に、前記ジッパ３の構成について説明する。
前記ジッパ３は、図２（ａ）（ｂ）に示すように、ジッパ３中央に形成された直線状の凹部６および凸部５が対向しており、これらを凹凸嵌合することにより、ジッパ３を閉封するとともに、ジッパ３の開封時においては、ジッパ上方の前後のフィルム８をそれぞれつまみ、互いに引き離すことにより、凹部６および凸部５の凹凸嵌合が開放されてジッパ３を開封するものである。
そして、ジッパ３の凹部６および凸部５の上方部分である上スカウト部７は、外方へと凸形状をなす凸面７Ｗを形成しており、特に、図２（ｂ）に示すように、凸面は湾曲形状をなす湾曲面７Ｗを形成している。この湾曲面７Ｗにより、後述する、ジッパ開封時において、湾曲面７Ｗの一部が平面形状７Ｈへと変形して開口形状を維持する開口保形機能を有するものである。よって、ジッパ開封後の内容物の取り出しを容易かつ安定して行なうことが可能である。 Next, the configuration of the zipper 3 will be described.
As shown in FIGS. 2A and 2B, the zipper 3 has a linear concave portion 6 and a convex portion 5 formed at the center of the zipper 3 facing each other. 3 and when the zipper 3 is opened, the front and rear films 8 above the zipper are respectively picked up and separated from each other, so that the concave and convex fitting of the concave portion 6 and the convex portion 5 is released and the zipper 3 is opened. Is.
And the upper scout part 7 which is the upper part of the recessed part 6 and the convex part 5 of the zipper 3 forms the convex surface 7W which makes a convex shape outward, in particular, as shown in FIG. The convex surface forms a curved surface 7W having a curved shape. The curved surface 7W has an opening shape retaining function for maintaining a shape of the opening by deforming a part of the curved surface 7W into a planar shape 7H when the zipper is opened, which will be described later. Therefore, it is possible to easily and stably take out the contents after opening the zipper.

次に、ジッパ開封後の、開口保形機能について説明する。
前述のとおり、包装体１０の開封時、包装体１０上部の前後のフィルム８をつまんで引き離すことにより、ジッパ３を開封するが、このとき、一定量のフィルム開封に伴い、図３（ａ）（ｂ）（ｃ）に示すように、前記ジッパ３の上スカウト部７の湾曲面７Ｗが平面形状７Ｈへと変形することとなる。 Next, the opening shape retaining function after opening the zipper will be described.
As described above, when the package 10 is opened, the zipper 3 is opened by pinching and separating the front and rear films 8 on the upper portion of the package 10. At this time, with the opening of a certain amount of film, FIG. (B) As shown in (c), the curved surface 7W of the upper scout portion 7 of the zipper 3 is deformed into a planar shape 7H.

特に、上スカウト部７の中央部分の凸面７Ｗの一部が平面形状７Ｈへと変形するとともに、以後この状態を維持する（開口保形機能）ことが可能である。
また、ジッパ３の剛性によっては、前記湾曲面７Ｗが一旦平面形状７Ｈへと変形した後、徐々に元の湾曲面７Ｗへと戻るため、開封後直ちに閉封してしまうことなく、時間的な猶予を生じることが可能である。 In particular, a part of the convex surface 7W at the center portion of the upper scout portion 7 is deformed into the planar shape 7H, and this state can be maintained thereafter (open shape retaining function).
Further, depending on the rigidity of the zipper 3, the curved surface 7W is once deformed into the planar shape 7H and then gradually returns to the original curved surface 7W. It is possible to create a grace period.

このように、本発明の開口保形機能を有するジッパ付き包装体１０は、ジッパ３の上スカウト部７を湾曲面７Ｗとすることにより、開封時に開口形状を維持する開口保形機能を有することが可能である。
しかしながら、ジッパ３の初期開封時において、ジッパ上方の前後のフィルム８が互いに接しやすく、このため、図４（ａ）に示すように、ジッパ上方のフィルム８間が閉塞Ｘしてしまい、ジッパ開封時にジッパ上方のフィルム８をつまみづらいという問題がある。 Thus, the zippered packaging body 10 having the opening shape retaining function of the present invention has the opening shape retaining function for maintaining the opening shape at the time of opening by forming the upper scout portion 7 of the zipper 3 as the curved surface 7W. Is possible.
However, when the zipper 3 is opened for the first time, the front and rear films 8 above the zipper are easily in contact with each other, and as a result, the gap between the films 8 above the zipper is closed X as shown in FIG. There is a problem that it is sometimes difficult to pinch the film 8 above the zipper.

このため、本発明の開口保形機能を有するジッパ付き包装体１０は、図４（ｂ）に示すように、ジッパ上方部分の前後のフィルム８に、内方へと凸形状の凸部９を形成することにより、常にジッパ上方の前後のフィルム８間に隙間１２を形成するため、前後のフィルム８がくっつくことなく、それぞれのフィルム８をつまんで、ジッパ３の開封をしやすくなる開封補助機能を有することが可能である。   For this reason, as shown in FIG. 4 (b), the package 10 with a zipper having the opening shape retaining function of the present invention has a convex portion 9 convex inwardly on the film 8 before and after the upper portion of the zipper. By forming, a gap 12 is always formed between the front and rear films 8 above the zipper, so that the front and rear films 8 do not stick together, and each film 8 can be pinched and the zipper 3 can be opened easily. It is possible to have

例えば、図５（ａ）（ｂ）（ｃ）に示すように、ジッパ上方のフィルム８に、内方へと凸形状の凸部９を複数個形成することにより、前記凸部９の高さ分の隙間をジッパ上方のフィルム８間に形成することが可能であり、ジッパ上方のフィルム８を指先等でつまみやすくなる効果がある。よって、ジッパ３の開封操作をよりスムースに行なうことが可能である。   For example, as shown in FIGS. 5A, 5B, and 5C, by forming a plurality of convex portions 9 inwardly on the film 8 above the zipper, the height of the convex portions 9 is increased. It is possible to form a minute gap between the films 8 above the zipper, and it is easy to pinch the film 8 above the zipper with a fingertip or the like. Therefore, the opening operation of the zipper 3 can be performed more smoothly.

前記凸部９は、前記ジッパ上方のフィルム８に、パンチ等により内方へと凸形状からなる凸部９を形成すればよく、凸部９の形状や形成方法は限定されるものではない。
また、前記凸部９は、少なくともジッパ上方の前後のフィルム８の何れか一方に形成すればよいが、より好ましくは、前後のフィルム８にそれぞれ凸部９を形成し、かつ凸部９が互いに対向する位置に形成することにより、ジッパ上方のフィルム８間にさらに大きな隙間１２を形成することが可能である。 The convex portion 9 may be formed by forming a convex portion 9 having a convex shape inwardly by punching or the like on the film 8 above the zipper, and the shape and forming method of the convex portion 9 are not limited.
The protrusions 9 may be formed on at least one of the front and rear films 8 above the zipper. More preferably, the protrusions 9 are formed on the front and rear films 8, respectively. By forming them at opposing positions, it is possible to form a larger gap 12 between the films 8 above the zipper.

以上のように、本発明の開口保形機能を有するジッパ付き包装体１０は、ジッパ３の上スカウト部７に、外方へと凸形状を有する凸面７Ｗを形成する簡単な構成により、開封時の開口形状を維持する開口保形機能を有することが可能である。さらには、ジッパ上方のフィルム８に、内方へと凸形状の凸部９を形成する簡単な構成により、ジッパ３の開封をしやすい開封補助機能を有することが可能である。よって、ジッパ３を開封操作から内容物の取り出しまでの一連の操作をスムースかつ簡単に行なうことが可能なジッパ付き包装体１０を提供することが可能である。   As described above, the zippered packaging body 10 having the opening retaining function of the present invention has a simple configuration in which the convex surface 7W having a convex shape outward is formed on the upper scout portion 7 of the zipper 3 at the time of opening. It is possible to have an opening shape-retaining function for maintaining the opening shape. Furthermore, it is possible to have an opening assisting function that facilitates opening of the zipper 3 by a simple configuration in which the convex portion 9 that is convex inward is formed on the film 8 above the zipper.

前記ＰＥＴフィルムやＯＮフィルムは、基材フィルムとして作用し、パウチに機械的強度のほか耐熱性、印刷適性などを付与する。また、中間層のアルミニウム箔、ＥＶＯＨフィルム、（シリカまたはアルミナ蒸着層）ＯＮフィルムは、パウチにガスバリヤー性を付与することが可能である。一軸延伸ＰＰフィルムは、本発明の包装体１０では、その延伸方向がパウチの開口部のフィルムを開封するための切取り線５の方向と一致するように積層することにより、開口部のフィルムを切除する際、切取り線５に沿って容易に引き裂いて開封できるようになる。   The PET film and the ON film act as a base film, and give the pouch not only mechanical strength but also heat resistance and printability. Further, the intermediate layer aluminum foil, EVOH film, and (silica or alumina deposited layer) ON film can impart gas barrier properties to the pouch. In the packaging body 10 of the present invention, the uniaxially stretched PP film is laminated so that the stretch direction thereof coincides with the direction of the tear line 5 for opening the film of the pouch opening, thereby cutting the film of the opening. In doing so, it can be easily torn and opened along the tear line 5.

そして、最内層のＣＰＰフィルムは、ヒートシール用のシーラント層として作用すると共に、耐熱性、低臭性に優れるので、パウチごと加圧加熱殺菌される流動食用のパウチには好ましく用いられる。尚、上述した各フィルム材と同様な作用効果を有するものであれば、前記の積層構成に限定されるものではなく、適宜変更して使用することができる。   The innermost CPP film acts as a sealant layer for heat sealing and is excellent in heat resistance and low odor. Therefore, it is preferably used for a liquid food pouch that is sterilized by heating and heating together with the pouch. In addition, if it has the same effect as each film material mentioned above, it will not be limited to the said laminated structure, It can change suitably and can be used.

また、本発明のジッパ３は、前記熱接着性樹脂層との熱接着性および加圧加熱殺菌に耐える耐熱性が必要であり、単独の樹脂では、ポリプロピレンを成形したものを用いることができ、また、４−メチルペンテン−１とプロピレンの共重合体、或いは、４−メチルペンテン−１の重合体とポリプロピレンなどとのブレンド樹脂を成形したものも用いることができる。   In addition, the zipper 3 of the present invention requires heat adhesion with the heat-adhesive resin layer and heat resistance that can withstand pressure heat sterilization, and a single resin can be molded polypropylene. Moreover, what shape | molded the blend resin of the copolymer of 4-methylpentene-1 and a propylene, or the polymer of 4-methylpentene-1 and a polypropylene can also be used.

また、初期開封時において開口部のフィルムを切除する際の起点となる前記ノッチ４を設ける方法のほか、レーザー光照射などによるハーフカット線を設ける方法、或いは、パウチの積層フィルムの中間層などに一軸延伸フィルムを積層する方法（この場合、一軸延伸フィルムは、その延伸方向が袋の開封方向と一致するように用いる）などがあり、これらは単独で用いてもよく、また、例えば、ノッチとハーフカット線、更には一軸延伸フィルムの積層などを組み合わせて用いることもできる。   In addition to the method of providing the notch 4 as a starting point when cutting the film of the opening at the time of initial opening, a method of providing a half cut line by laser light irradiation or the like, or an intermediate layer of a laminated film of pouches, etc. There is a method of laminating a uniaxially stretched film (in this case, the uniaxially stretched film is used so that its stretch direction coincides with the opening direction of the bag), and these may be used alone. A combination of a half-cut line and a laminate of uniaxially stretched films can also be used.

前記のノッチ４は、通常、Ｉ字形やＶ字形などのノッチが利用されているが、形状は特に限定されず、切り取り方向に鋭角部分を有する形状であれば何でも使用することができる。また、ハーフカット線を設ける場合も、直線状のハーフカット線に限らず、ミシン目状など断続的なハーフカット線で設けることもできる。更に、このようなハーフカット線は、１本でもよいが、引き裂き方向がずれた場合を想定して、中心のハーフカット線の両側に各１本、または各２本など複数本のハーフカット線を平行または中心のハーフカット線に収束する形状などに設けることもできる。更にこれらの複数を適宜組み合わせて設けたものであってもよい。   The notch 4 is usually a notch such as an I-shape or a V-shape, but the shape is not particularly limited, and any shape having an acute angle portion in the cutting direction can be used. Moreover, when providing a half cut line, it is not limited to a straight half cut line, and may be provided by an intermittent half cut line such as a perforation. Furthermore, the number of such half-cut lines may be one, but assuming that the tearing direction is deviated, a plurality of half-cut lines such as one or two on each side of the center half-cut line. Can be provided in a shape that converges to a parallel or central half-cut line. Further, a plurality of these may be provided in appropriate combination.
