Description
本考案は、一般に熱収縮性包装用袋に関するものであり、より特定的には、装着した状態で自立可能な角型包装体を与える熱収縮性包装用袋に関する。本考案は、またそのような熱収縮性包装用袋で包装された角型包装体に関する。 The present invention generally relates to a heat-shrinkable packaging bag, and more particularly to a heat-shrinkable packaging bag that provides a square package that can be self-supported in a mounted state. The present invention also relates to a square package packaged in such a heat-shrinkable packaging bag.
図３は、従来の角型電池用の熱収縮性包装用袋の製造工程及び得られた熱収縮性包装用袋を角型電池に装着して熱収縮させる工程を示す図である。 FIG. 3 is a diagram showing a conventional process for producing a heat-shrinkable packaging bag for a square battery and a process for attaching the obtained heat-shrinkable packaging bag to a square battery and performing heat shrinkage.
図３（Ａ）を参照して、押出機先端の環状ダイスから押し出された筒状の溶融樹脂が、一旦冷水にて冷却固化され、加熱された後空気を吹き込まれてチューブ状に延伸され、そのまま冷却され、ロールに巻き取られてなる熱収縮性チューブ１を準備する。図３（Ａ）、（Ｂ）を参照して、フィルムの流れ方向Ｄに対して直角の方向に熱溶断シールすることにより熱シール部３を形成し、ナイフでチューブカットして、熱収縮性包装用袋２を製造する。図３（Ｃ）を参照して、被包装体である角型電池４を準備する。図３（Ｄ）を参照して、角型電池４の底部が熱収縮性包装用袋２の底部に包まれるように、角型電池４を熱収縮性包装用袋２内に挿入する。次いで、熱収縮させて角型電池４に熱収縮性包装用袋２を装着させると、角型包装体５が完成する。従来の方法では、熱収縮性チューブ２の底部にせびれ状の硬い熱シール部３が現れる。また、角立ち６が残る。 With reference to FIG. 3 (A), the cylindrical molten resin extruded from the annular die at the end of the extruder is once cooled and solidified with cold water, heated and then blown into air to be drawn into a tube, A heat-shrinkable tube 1 that is cooled as it is and wound up on a roll is prepared. Referring to FIGS. 3A and 3B, heat seal portion 3 is formed by heat fusing and sealing in a direction perpendicular to film flow direction D, and the tube is cut with a knife, and heat shrinkability is achieved. The packaging bag 2 is manufactured. With reference to FIG.3 (C), the square battery 4 which is a to-be-packaged body is prepared. With reference to FIG. 3D, the square battery 4 is inserted into the heat-shrinkable packaging bag 2 so that the bottom of the square battery 4 is wrapped in the bottom of the heat-shrinkable packaging bag 2. Next, when the heat shrinkable packaging bag 2 is attached to the square battery 4 by heat shrinking, the square package 5 is completed. In the conventional method, a numbing hard heat seal portion 3 appears at the bottom of the heat-shrinkable tube 2. Moreover, the corner stand 6 remains.
図４は、図３（Ｄ）におけるＡ部拡大図である。さて、従来の角型包装体５では、必然的に、底面に硬い熱シール部３が残ってしまうので、この熱シール部３により、電池を鉛直方向に立てることができないという問題があった。また、チューブの側面の余り部分が角立ちし、熱収縮しても、図３（Ｄ）及び図４に示すように、角立ち６が残り綺麗に仕上がらないという問題があった。このような問題は、角型電池だけでなく、角型の被包装体の全ての場合に生じていた。 FIG. 4 is an enlarged view of part A in FIG. Now, the conventional square package 5 inevitably has a hard heat-sealed portion 3 left on the bottom surface, so that there is a problem that the heat-sealed portion 3 cannot stand the battery in the vertical direction. Moreover, even if the excess part of the side surface of the tube is angulated and heat shrinks, there is a problem that the angling 6 remains and is not finished cleanly as shown in FIGS. Such a problem has occurred not only in the prismatic battery but also in all cases of the rectangular package.
この考案は上記のような問題点を解決するためになされたもので、包装体を鉛直方向に立てることができるように改良された熱収縮性包装用袋を提供することを目的とする。 The present invention has been made to solve the above-described problems, and an object thereof is to provide a heat-shrinkable packaging bag which is improved so that the packaging body can be erected in the vertical direction.
この考案の他の目的は、チューブの余り部分が角立ちしないように改良された熱収縮性包装用袋を提供することにある。 Another object of the present invention is to provide a heat-shrinkable packaging bag which is improved so that the excess portion of the tube does not stand.
この考案の他の目的は、そのような熱収縮性包装用袋で包装された角型包装体を提供することにある。 Another object of the present invention is to provide a square package packaged in such a heat-shrinkable packaging bag.
この考案に係る熱収縮性包装用袋は、底部にガゼット（マチ）が入れられ、両側部が熱シールされてなることを特徴とする。 The heat-shrinkable packaging bag according to the present invention is characterized in that a gusset (gusset) is placed at the bottom and both sides are heat-sealed.
底部に入れられたガゼットは、包装体を挿入したとき、押し広げられ、その面は平坦になる。硬い熱シール部は、両側部にでき、底部に熱シール部が残らない。また、側部のチューブ余り部分は、内側に折り畳まれ、収縮する。 The gusset placed in the bottom is spread when the package is inserted, and its surface becomes flat. Hard heat seals can be made on both sides, leaving no heat seals at the bottom. Further, the excess portion of the side tube is folded inward and contracted.
上記包装用熱収縮性チューブは、熱可塑性樹脂で形成され、ポリエチレンテレフタレート系樹脂又はポリプロピレン系樹脂が好ましく用いられる。特にポリエチレンテレフタレート系樹脂が好ましい。 The packaging heat-shrinkable tube is formed of a thermoplastic resin, and a polyethylene terephthalate resin or a polypropylene resin is preferably used. Polyethylene terephthalate resin is particularly preferable.
上記ガゼットは、角型被包装体の底幅の１／２幅程度を折り込んでなるのが好ましい。これにより、チューブの余り部分の量が少なくなる。 The gusset is preferably formed by folding about a half width of the bottom width of the rectangular package. Thereby, the quantity of the excess part of a tube decreases.
この考案の他の局面に従う角型包装体は、上記特徴を有する熱収縮性包装用袋に、その底部が上記ガゼット部に包まれて装着されてなる。 A square package according to another aspect of the present invention is formed by attaching a bottom portion of a wrapping bag to the heat-shrinkable packaging bag having the above characteristics.
側部のチューブ余り部分は、内側に折り畳まれて収縮しているので、綺麗に仕上がる。 The extra tube part on the side is folded inward and shrunk, resulting in a beautiful finish.
本考案に係る熱収縮性包装用袋によれば、底部に入れられたガゼットは、包装体を挿入したとき、押し広げられ、その面は平坦になる、かつ硬い熱シール部は、両側部にでき、底部に熱シール部が残らない形状であるので、装着した状態で角型被包装体を立てることができる。また、側部のチューブ余り部分は、内側に折り畳まれ、収縮で綺麗に仕上がる。 According to the heat-shrinkable packaging bag of the present invention, the gusset placed in the bottom is spread when the package is inserted, the surface becomes flat, and the hard heat-sealed portion is formed on both sides. In addition, since the heat seal portion does not remain at the bottom, the rectangular package body can be erected in the mounted state. In addition, the side tube excess part is folded inward and finished beautifully by contraction.
包装体を鉛直方向に立てることができるように改良された熱収縮性包装用袋を得るという目的を、底部にガゼットが入れられ、両側部が熱シールされてなる熱収縮性包装用袋を形成することによって実現した。以下、本考案の実施の形態を図を用いて説明する。なお、各図中、同一又は相当する部分には同一の参照番号を付し、その説明を繰り返さない。 For the purpose of obtaining a heat-shrinkable packaging bag that has been improved so that the package can stand in the vertical direction, a heat-shrinkable packaging bag is formed in which a gusset is placed at the bottom and both sides are heat-sealed. Realized by doing. Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and the description thereof will not be repeated.
図１は、本考案の実施例に係る角型電池包装用の熱収縮性チューブの製造工程及び得られた熱収縮性包装用袋を角型電池に装着して熱収縮させる工程を示す図である。 FIG. 1 is a diagram illustrating a process for manufacturing a heat-shrinkable tube for rectangular battery packaging according to an embodiment of the present invention and a process for heat-shrinking the obtained heat-shrinkable packaging bag attached to a square battery. is there.
図１（Ａ）を参照して、押出機先端の環状ダイスから押し出された筒状の溶融樹脂が、一旦冷水にて冷却固化され、加熱された後空気を吹き込まれてチューブ状に延伸され、そのまま冷却され、ロールに巻き取られてなる熱収縮性チューブ１を準備する。この熱収縮性チューブを沸騰水で３０秒間処理した際の熱収縮率は、熱収縮性チューブの流れ方向で３５〜５５％であり、熱収縮性チューブの周方向で５〜１５％である。熱収縮性チューブの材質は、ポリエチレンテレフタレート樹脂であり、例えば、株式会社ベルポリエステルプロダクツ製ベルペット等を例示できる。 Referring to FIG. 1 (A), the cylindrical molten resin extruded from the annular die at the tip of the extruder is once cooled and solidified with cold water, heated and then blown into air to be drawn into a tube, A heat-shrinkable tube 1 that is cooled as it is and wound up on a roll is prepared. When this heat-shrinkable tube is treated with boiling water for 30 seconds, the heat shrinkage rate is 35 to 55% in the flow direction of the heat-shrinkable tube and 5 to 15% in the circumferential direction of the heat-shrinkable tube. The material of the heat-shrinkable tube is polyethylene terephthalate resin, and examples thereof include Bell Polypet Products made by Bell Polyester Products.
図１（Ａ）を参照して、フィルムの流れ方向Ｄに沿って、底部となる部分にチューブ折り込みを行う。チューブ折り込みは、被包装体例えば角型電池の底幅の１／２幅を折り込む。これにより、底部にガゼット７が形成される。次いでフィルムの流れ方向Ｄに対して直角の方向に２箇所を熱溶断シールすることにより、後述する熱シール部３を形成する。２箇所の熱シール部３の間隔は、被包装体の長手方向の幅に略等しくする。チューブカット開きは、チューブの上部開口部を形成するためのもので、ガゼットを設ける部分の反対側の辺をナイフ１０により切り開く（側縁部分を細くトリミングする場合もある）。これらの工程を経て、図１（Ｂ）に示す、底部にガゼット７が入れられ、両側部が熱シールされた熱シール部３を有する熱収縮性包装用袋２が形成される。 Referring to FIG. 1A, the tube is folded into the bottom portion along the flow direction D of the film. In the tube folding, a half width of the bottom width of a packaged object, for example, a square battery is folded. Thereby, the gusset 7 is formed in the bottom. Subsequently, the heat sealing part 3 mentioned later is formed by carrying out hot-melt sealing of two places in the direction orthogonal to the flow direction D of a film. The space | interval of the two heat seal parts 3 is made substantially equal to the width | variety of the longitudinal direction of a to-be-packaged body. The tube cut opening is for forming the upper opening of the tube, and the side opposite to the portion where the gusset is provided is cut open by the knife 10 (the side edge portion may be trimmed narrowly). Through these steps, a heat-shrinkable packaging bag 2 having a heat seal portion 3 in which a gusset 7 is placed at the bottom and both sides are heat sealed is formed as shown in FIG.
従来の方法では、フィルムの流れ方向Ｄに対して直角な面を有する開口部ができたが、本考案に係る包装用熱収縮性チューブでは、開口部８はフィルムの流れ方向Ｄに対して平行な面を有する。すなわち、得られた熱収縮性包装用袋２の主収縮方向が、従来のものと本考案に係るものとでは、互いに直行するのも特徴である。また、本考案に係る熱収縮性包装用袋２では、熱収縮性包装用袋２の側部に熱シール部３が現れる。 In the conventional method, an opening having a surface perpendicular to the film flow direction D was formed, but in the packaging heat-shrinkable tube according to the present invention, the opening 8 is parallel to the film flow direction D. It has a nice surface. That is, the main shrinkage direction of the obtained heat-shrinkable packaging bag 2 is also characterized in that the conventional one and the one according to the present invention are perpendicular to each other. Moreover, in the heat-shrinkable packaging bag 2 according to the present invention, the heat seal portion 3 appears on the side portion of the heat-shrinkable packaging bag 2.
図１（Ｃ）を参照して、被包装体である角型電池４を準備する。図１（Ｃ）、（Ｄ）を参照して、角型電池４の底部が熱収縮性包装用袋２の底部に包まれるように、角型電池４を熱収縮性包装用袋２内に挿入する。次いで、熱収縮させて角型電池４に熱収縮性包装用袋２を装着させると、その底部がガゼット部７に包まれて装着されてなる角型包装体５が完成する。ガゼット部７は収縮して電池の底面に密着すると平坦な面になるので、角型包装体５は立つことができる。 With reference to FIG.1 (C), the square battery 4 which is a to-be-packaged body is prepared. Referring to FIGS. 1C and 1D, the prismatic battery 4 is placed in the heat-shrinkable packaging bag 2 so that the bottom of the prismatic battery 4 is wrapped in the bottom of the heat-shrinkable packaging bag 2. insert. Next, when the heat-shrinkable packaging bag 2 is attached to the square battery 4 by heat-shrinking, the square package 5 in which the bottom part is wrapped and attached to the gusset part 7 is completed. Since the gusset portion 7 contracts and becomes a flat surface when it closely contacts the bottom surface of the battery, the square package 5 can stand.
図２は、図１（Ｄ）におけるＢ部拡大図である。本考案に係る熱収縮性包装用袋によれば、硬い熱シール３部はチューブの両側部にでき、底部に熱シール部が残らない形状である。また、底部に形成されたガゼット部７は収縮して電池の底面に密着すると平坦な面になるので、角型包装体５は立つことができる。さらに、側部のチューブ余り部分９は、内側に折り畳まれ、収縮で綺麗に仕上がる。 FIG. 2 is an enlarged view of a portion B in FIG. According to the heat-shrinkable packaging bag of the present invention, the hard heat seal 3 parts can be formed on both sides of the tube, and the heat seal part does not remain on the bottom. Moreover, since the gusset part 7 formed in the bottom part shrink | contracts and it adheres to the bottom face of a battery, it will become a flat surface, Therefore The square package 5 can stand. Further, the side tube surplus portion 9 is folded inward and finished finely by contraction.
