  • Patent number: 8695869
    Abstract: The packaging container includes a bag assembly having first and second sealing sections formed at two opposite sides of four sides, and a third sealing section where one side of the remaining two sides is a folding line, wherein the one remaining side is opened. The opened side is joined together in a state in which an object is placed inside the bag assembly, a fourth sealing section is formed at an angle substantially orthogonal to the third sealing section, a pair of first and second triangles with the fourth sealing section as the shared bottom side are formed, and a pair of third and fourth triangles with the third sealing section as the shared bottom side are formed. The first and second sealing sections located on the vertical lines of the first and second triangles are used as an unsealing guide for tearing.
