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).

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.

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.

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. A front panel 21a, a side panel 21b, a top panel 24a, 24b, 24c that forms a top wall of the container, a bottom panel that forms a bottom wall of the container, and a flap 25 that is folded and sealed to the side wall or bottom. It consists of flap panels 25a, 25b, 25c, and a crease line 26 is formed at the boundary between these panels.

In addition to the brick container and gable roof container, there are a single-flow roof container, a pentagonal container, a hexagonal container, and an octagonal container. (See patent literature)
