Description

包装容器の製造法及び包装容器Packaging container manufacturing method and packaging container
本発明は、牛乳、ジュース、アルコール飲料、ミネラルウォータ、緑茶など他、液体製品を充填する包装容器の製造方法及びその包装容器に関するに関する。 The present invention relates to a method for producing a packaging container filled with a liquid product, such as milk, juice, alcoholic beverage, mineral water, green tea, and the like, and the packaging container.
柔軟性に富んだ紙製包装積層材料は多年にわたって液体食品の他、液体製品を包装するために用いられてきた。牛乳、ジュース、清酒、焼酎、ミネラルウォーター及びその他飲料のための図１０に示すような包装容器２０は、例えば、繊維質基材（例えば、紙など）／プラスチック積層体に折目線が付けられたウェブ状包装積層材料を、その長手方向の縦シールによりチューブ状に成形し、チューブ状に成形された包装材料内に被充填物を充填し、チューブ状包装材料を横断方向に横シールし、枕状の包装体（一次形状容器）に成形する。 Flexible paper packaging laminates have been used for many years to package liquid products as well as liquid foods. A packaging container 20 such as that shown in FIG. 10 for milk, juice, sake, shochu, mineral water and other beverages, for example, is creased in a fibrous base material (eg, paper, etc.) / Plastic laminate. A web-like packaging laminate material is formed into a tube shape by a longitudinal seal in the longitudinal direction, the filling material is filled into the tube-shaped packaging material, the tube-like packaging material is transversely sealed in the transverse direction, and a pillow Into a package (primary shape container).
枕状の包装体を横シール部分で容器１個分ごとに切断し、折目線に沿って山折り若しくは谷折に折畳んで、図１０に示すような、側壁を形成するパネル２１ａ、２１ｂ、縦シール部２２、フィンの横シール部２３、頂壁を形成するパネル２４、側壁等にシールされるフラップ（頂壁や底部を形成する際に生じる折り込み片）２５などからなるレンガ状の容器２０が成形される。 Panels 21a, 21b that form side walls as shown in FIG. 10 by cutting a pillow-shaped package into one container at a horizontal seal portion and folding it into a mountain fold or a valley fold along the fold line. A brick-like container 20 comprising a vertical seal portion 22, a fin horizontal seal portion 23, a panel 24 forming a top wall, a flap (folded piece generated when forming a top wall or a bottom portion) 25 sealed to a side wall or the like. Is formed.
ゲーブルトップ状（屋根型）の紙製包装容器では、紙製包装材料を所定の形状に切断し、容器縦方向にシールしたブランクスを得、充填機内でブランクスの底をシールした後に上部開口から牛乳、ジュース又はその他の飲料の被充填物を充填し、上部をシールして得られる。これらの包装材料には、その表面に包装容器製品の外観デザインが印刷される。 For gable-top (roof-type) paper packaging containers, cut the paper packaging material into a predetermined shape, obtain blanks sealed in the container vertical direction, seal the bottom of the blanks in the filling machine, and then milk from the top opening Filled with juice or other beverage filling and sealed at the top. These packaging materials have the appearance design of the packaging container product printed on the surface thereof.
ウェブ状包装材料は、容器１個分の折れ目線が繰返し連続的に施される。容器１個分の部分的な包装材料を示す図１１を参照する。折目線が付けられたウェブ状包装材料は、容器１個分の包装材料２７に、縦シール用のシール領域２８、チューブ状包装材料の横断方向に横シールを施す横シール領域２９、容器器壁を形成するフロントパネル２１ａ、サイドパネル２１ｂ、容器の頂壁を形成するトップパネル２４ａ、２４ｂ、２４ｃ、容器底壁を形成するボトムパネル、折り畳まれて側壁若しくは底部にシールされるフラップ２５を形成するフラップパネル２５ａ、２５ｂ、２５ｃからなり、それらのパネルの境には、それぞれに折目線２６が形成されている。 The web-shaped packaging material is repeatedly and continuously provided with a fold line for one container. Reference is made to FIG. 11 which shows a partial packaging material for one container. The web-shaped packaging material with a crease line is composed of a packaging material 27 for one container, a sealing region 28 for vertical sealing, a lateral sealing region 29 for lateral sealing in the transverse direction of the tubular packaging material, a container wall. Forming a front panel 21a, side panels 21b, top panels 24a, 24b, 24c forming the top wall of the container, bottom panels forming the bottom wall of the container, and a flap 25 that is folded and sealed to the side wall or bottom.

In addition, the paper packaging containers are usually arranged on a merchandise display shelf with a short back in a retail store, and the consumer can easily take out by holding the side walls on both sides.
この発明の別の態様である三角形状上部パネル３６ａに大型の注出口４０を設けた包装容器の第３実施例を、図８を参照して説明する。
図８では、大型のスクリューキャップ４０を取り付けた容器例を示す。この態様では、包装容器３０は、折目線に沿って折畳んで形成された頂壁３１、側壁３２及び底壁３３を持ち、この折畳みの過程で形成されたフィン３４及びフラップ３５は、上部フラップ及びフィンが三角形状上部パネルへ付けられ、下部フラップ及びフィンが底壁へ付けられる。三角形状上部パネル３６ａへキャップ４０が付けられた様子を図８に示す。 A third embodiment of a packaging container in which a large spout 40 is provided in a triangular upper panel 36a according to another aspect of the present invention will be described with reference to FIG.
In FIG. 8, the example of a container which attached the large sized screw cap 40 is shown. In this embodiment, the packaging container 30 has a top wall 31, a side wall 32, and a bottom wall 33 formed by folding along a fold line, and the fins 34 and the flaps 35 formed in the folding process are formed as upper flaps. And fins are attached to the triangular top panel, and lower flaps and fins are attached to the bottom wall. FIG. 8 shows a state in which the cap 40 is attached to the triangular upper panel 36a.
図８の側面図に示すように、頂壁３１及び底壁が、包装容器３０が直立した際に、実質的に水平である。
図８の側面図に示すように、シンプルであるが新規斬新な容器外観となる。
この態様においては、三角形状上部パネル３６ａに大型のスクリューキャップ４０が設けられている。
大型の注出口によって、容易に液体製品を注ぎ出すことができる。
前面の張出しによって、この張出しから消費者が容易に注ぎ出すことができる。すなわち、張り出しによって、手が小さい幼児子供が消費者であっても、比較的に把持し易い。また、通常、紙製包装容器は、小売店舗で背の低い奥のある商品陳列棚に並べられ、消費者が、両側の側壁を把持して容易に取り出すことができる。 As shown in the side view of FIG. 8, the top wall 31 and the bottom wall are substantially horizontal when the packaging container 30 stands upright.
As shown in the side view of FIG. 8, the appearance of the container is simple but novel.
In this embodiment, a large screw cap 40 is provided on the triangular upper panel 36a.
The liquid product can be easily poured out by a large spout.
The front overhang allows the consumer to easily pour out from this overhang. That is, even if the infant child with a small hand is a consumer by overhanging, it is comparatively easy to hold. In addition, the paper packaging containers are usually arranged on a merchandise display shelf with a short back in a retail store, and the consumer can easily take out by holding the side walls on both sides.
第１実施例の包装容器３０の製造法の一例を、枕状包装体１３から成形される工程を示す図９を参照して具体的に説明する。
図９に示す成形ステップ（ａ）において、図１２に示すように、液体製品がチューブ状包装積層材料１内に充填され、横シールされ、切断されて形成された枕状包装体１３を得て、折目線に沿って予備的に折込まれた枕状包装体１３を準備する。
この準備ステップにおいて、充填は、チューブ状包装材料内の断面積を調整して最終形状の包装容器の一定容量に相当する容量の液体製品を包装材料内に充填する。具体的には、チューブ断面形状が、楕円状、瓢箪状、略三菱状などである。
更に、横シールにおいて、上記の一定容量を維持して密封する。
成形ステップ（ｂ）において、上下の横シール部分（フィン）３４の両端を左右側に突き出す。
成形ステップ（ｃ）において、上の横シール部分（フィン）３４を三角形状上部パネル３６ａ側に倒し、上方の２つの折り込み片（フラップ）３５を形成し、三角形状上部パネル３６の壁面上に付け、下方の２つの折り込み片（フラップ）３５を形成し底壁パネル３３の壁面上に付ける。
上記の成形ステップにおいて、包装体の器壁を内側に変形させて一定容量を維持する。例えば、器壁面積の広い側壁側を圧して窪みを形成して維持する。
包装材料が可撓性を持つので、包装容器に損傷、欠陥を与えず、効果的に成形することができる。 An example of the manufacturing method of the packaging container 30 of the first embodiment will be specifically described with reference to FIG.
In the molding step (a) shown in FIG. 9, as shown in FIG. 12, a pillow-shaped packaging body 13 is obtained that is formed by filling a liquid product into the tubular packaging laminate material 1, transversely sealing, and cutting. Then, a pillow-shaped package 13 that is preliminarily folded along the fold line is prepared.
In this preparation step, the filling is performed by adjusting the cross-sectional area in the tubular packaging material to fill the packaging material with a liquid product having a volume corresponding to a certain volume of the final-shaped packaging container. Specifically, the cross-sectional shape of the tube is an ellipse shape, a bowl shape, a substantially Mitsubishi shape, or the like.
Further, in the horizontal seal, the above-mentioned constant volume is maintained and sealed.
In the forming step (b), both ends of the upper and lower horizontal seal portions (fins) 34 are protruded to the left and right sides.
In the forming step (c), the upper horizontal seal portion (fin) 34 is tilted to the triangular upper panel 36a side to form two upper folded pieces (flaps) 35, which are attached to the wall surface of the triangular upper panel 36. Two lower folding pieces (flaps) 35 are formed and attached to the wall surface of the bottom wall panel 33.
In the molding step, the container wall of the package is deformed inward to maintain a constant capacity. For example, the side wall having a large vessel wall area is pressed to form and maintain a depression.
Since the packaging material has flexibility, the packaging container can be effectively molded without causing damage and defects.
なお、本発明は前記実施の形態に限定されるものではなく、本発明の趣旨に基づいて種々変形させることが可能であり、それらを本発明の範囲から排除するものではない。 In addition, this invention is not limited to the said embodiment, It can change variously based on the meaning of this invention, and does not exclude them from the scope of the present invention.
この発明は、液体食品の包装充填の製造に適用することができる。 The present invention can be applied to the manufacture of liquid food packaging.
