Summary: | PROBLEM TO BE SOLVED: To provide a packaging container not losing design, even when inner pressure changes relatively to outer pressure.SOLUTION: A packaging container used for sealing and packaging a content and using paper as a portion of a material includes a bottom part, and a cylindrical side surface part higher in rigidity than the bottom part. In the outer surface part of the bottom part, a plurality of ruled lines are disposed radially when seen from the center of the bottom part. When the inner pressure of the packaging container changes relatively to outer pressure, an atmospheric pressure difference is absorbed by expansion and contraction of the bottom part, and the change of the appearance of the side surface part is suppressed. |
