This patent relates to a dilute parallelepiped type packaging container and a herringbone top type packaging container for containing liquids such as milk. This patented product is made by folding and sealing multiple layers of packaging material, including two planar sections and four vertical panels. The packaging container formed by the vertical wall panel, the main wall panel and the auxiliary wall panel between the two wall panels is larger in volume when the packaging material used is the same as the existing packaging container. The auxiliary wall is formed by straight vertical fold lines, and each of the upper and lower end portions also has a pair of oblique broken lines intersecting at one point. In the blank used for the packaging container, most of the length of the panel is formed by straight, parallel, vertical fold lines.
