本発明は、包装材料をシールする装置、ジュースや牛乳などの液体食品などを充填する包装容器用包装充填装置及び包装材料のシール方法に関する。 The present invention relates to an apparatus for sealing a packaging material, a packaging filling apparatus for a packaging container for filling liquid food such as juice and milk, and a sealing method for the packaging material.
牛乳、ジュース、ミネラルウォーターなどの飲料、流動食品などの常温保存可能な紙包装容器は、例えば、熱可塑性材料最外層、紙基材層、導電性バリア層（例えば、アルミ箔）、ヒートシール性最内層からなる包装積層材料から得られる。 Paper packaging containers that can be stored at room temperature, such as beverages such as milk, juice, mineral water, and liquid foods, are, for example, outermost layers of thermoplastic materials, paper base layers, conductive barrier layers (for example, aluminum foil), heat sealability It is obtained from a packaging laminate material consisting of the innermost layer.
図６に液体食品用紙包装容器の例を示す。
この液体食品用紙包装容器には、頂面６１に開封部６２を有する紙製包装容器と、液体食品を注ぎ出すための再封止可能な開封装置６３を備える包装容器とがある。通常、開封装置はポリエチレン、ポリプロピレン、ポリスチレンなどのプラスチックから成形されている。
図６（Ａ）、（Ｂ）の液体食品用紙包装容器の例では、紙容器１４（図６（Ａ））とプラスチック開封装置６３をも備える容器１（図６（Ｂ））とがある。
プラスチック開封装置６３を備える紙容器１は、頂面６１に、開封装置取付前の紙製包装容器の斜視図をも示す図６（Ａ）のように、開封部６２を有する。開封部６２は、容易に開封されるように、弱め線若しくはパンチ穴にフィルムが貼られたプリラミネートホール（ＰＬＨ）からなる。開封装置６３は、注出口とこれを覆う再封止可能なキャップと、開封部６２の外周面と接合される下面が取付面のフランジとからなる。使用（開封）時には、開封装置６３が開封部６２を破断して開封する。
FIG. 6 shows an example of a liquid food paper packaging container.
This liquid food paper packaging container includes a paper packaging container having an opening 62 on the top surface 61 and a packaging container having a resealable opening device 63 for pouring out liquid food. Usually, the opening device is molded from plastics such as polyethylene, polypropylene, and polystyrene.
In the example of the liquid food paper packaging container of FIGS. 6A and 6B, there is a paper container 14 (FIG. 6A) and a container 1 (FIG. 6B) also including a plastic opening device 63.
The paper container 1 provided with the plastic opening device 63 has an opening portion 62 on the top surface 61 as shown in FIG. 6A which also shows a perspective view of the paper packaging container before the opening device is attached. The opening portion 62 is made of a pre-lamination hole (PLH) in which a film is attached to a weakening line or a punch hole so as to be easily opened. The unsealing device 63 includes a spout, a resealable cap that covers the spout, and a flange whose attachment surface is a lower surface joined to the outer peripheral surface of the unsealing portion 62. At the time of use (opening), the opening device 63 breaks and opens the opening part 62.
図３に、図６に示す包装容器を製造する装置の一例を示す。
その例に示す充填機では、紙基材層の内外層に熱可塑性材料層を有しロール状に巻かれた包装材料ウェブ１を巻き出し、ローラにより充填機内を搬送し、シーリングテープ２を包装材料縁部に接合するアプリケータ３を経て、滅菌剤槽４内で包装材料ウェブを滅菌し、エアナイフ５で滅菌剤が除去され、無菌室４０に入り、成形ローラ６によりチューブ状に成形し、包装材料の両端部を重ねてオーバーラップを形成し、オーバーラップで縦線方向に縦シールエレメント８によりチューブ縦方向にシールし、そのチューブ内に充填パイプ７から内容液の液体食品を充填し、このチューブを液面下で包装容器１個分に相当する長さ分だけ下方に送りながら、横シール装置１０のシールジョーとカウンタージョーにより横断方向に横シールし、同時に枕状予備成形体に連続的に成形し、繋がった枕状予備成形体１２のシール帯域の中間をナイフなどの切断手段により切断して個々の枕状予備成形体１３に切り離し、最終成形装置１５で枕状予備成形体の上下のフラップを折り曲げて最終形態の包装充填容器１４に成形する。
FIG. 3 shows an example of an apparatus for manufacturing the packaging container shown in FIG.
In the filling machine shown in the example, a packaging material web 1 having a thermoplastic material layer on the inner and outer layers of a paper base material layer is unwound, and the inside of the filling machine is conveyed by a roller, and the sealing tape 2 is packaged. Via the applicator 3 joined to the material edge, the packaging material web is sterilized in the sterilant tank 4, the sterilant is removed by the air knife 5, enters the sterilization chamber 40, and is formed into a tube shape by the forming roller 6, Both ends of the packaging material are overlapped to form an overlap, and the overlap is sealed in the vertical direction of the tube by the vertical seal element 8 in the vertical direction, and the liquid food of the content liquid is filled into the tube from the filling pipe 7, While this tube is sent downward by a length corresponding to one packaging container under the liquid level, it is transversely sealed in the transverse direction by the sealing jaw and counter jaw of the transverse sealing device 10 and simultaneously Continuously molded into a pillow-shaped preform, and the middle of the seal band of the connected pillow-shaped preform 12 is cut by a cutting means such as a knife and separated into individual pillow-shaped preforms 13, and a final molding device 15.
