Abstract

The present invention addresses the problem of providing a packaging container with a novel triangular cross section and a production method for said container. [Solution] A packaging container obtained by: forming a tube by vertically sealing a web-shaped packaging material; filling the tube-shaped packaging material; horizontally sealing the tube-shaped packaging material in the transverse direction thereof; forming pillow-shaped packaging bodies; cutting off individual pillow-shaped packaging bodies; and forming the same into a final shape by folding along creases to form a top wall, side walls, and a bottom wall and attaching formed fins and flaps to said walls. The top wall and bottom wall have a triangular shape; and the cross-section in the transverse direction of a packaging container main body formed by three ridgelines that connect the triangulation points of the top wall and the triangulation points of the bottom wall is a triangular prism shape.

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、緑茶などの他、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 liquid products in addition to milk, juice, alcoholic beverages, mineral water, green tea, and the like, and to 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、クッション形若しくは枕状の包装体（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. The web-like packaging laminate material is formed into a tube shape by the longitudinal seal in the longitudinal direction, the filling material is filled into the packaging material formed in the tube shape, the tube-like packaging material is laterally sealed in the transverse direction, and cushioned. Molded into a shaped or pillow-shaped package (primary shape container).

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 reducing the cross-sectional area in the tubular packaging material and filling the packaging material with a liquid product having a volume corresponding to a fixed 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 molding step (b), the side wall on the side wall 32b is pressed inward so that both ends of the upper and lower horizontal seal portions (fins) 34 protrude toward the side wall 32b.
In the molding step (c), the upper and lower horizontal seal portions (fins) 34 are tilted toward the rear side wall 32c to form two upper folding pieces (flaps) 35, which are attached to the wall surface of the side wall panel 32b, and the lower two One folding piece (flap) 35 is formed and attached on the wall surface of the side wall panel 32b.
In the molding step, the container wall of the package is deformed inward to maintain a constant capacity. For example, as shown in FIG. 9B, the side wall 32c or / and 32b side having a large vessel wall area is pressed and formed to maintain a depression.
Since the packaging material has flexibility, the packaging container can be effectively molded without causing damage and defects.
