PROBLEM TO BE SOLVED: To provide a packaging container which can be unsealed by easily gripping tabs of a lid member and a bottom member which become a trigger for the unsealing of an unsealing port in the sealed packaging container having sealability for the preservation or the protection of a content, and easy openability in use. SOLUTION: In this sealed packaging container, forming of which the depth is from 0.6 mm to 3.0 mm is performed at two locations or more in a range which is 50% or more of a bottom material section to be formed into an unsealing port of the container which is continuously formed on the sealed section. Thus, the unsealing port is made to be easier to grip by reducing the joining between the lid member and the bottom member for the packaging container. COPYRIGHT: (C)2005,JPO&NCIPI
