PROBLEM TO BE SOLVED: To provide a container capable of improving easy openability more.SOLUTION: A weakened part 26 is formed by pressing a pressing body at an end part of an opening part of a container 20 of a laminated structure having a seal layer 251 and a base material layer 252. In the weakened part 26, the seal layer 251 is provided with a missing part 264, and an upper expansion part 262 expanding toward a side opposite from a bottom is formed at the end part of the opening part 22 of the base material layer 252. Since a boundary surface between the base material layer 252 and the seal layer 251 is bent to an upper side for pulling up a lid 30 when opening the lid 30, the seal layer 251 can easily undergo interfacial peeling. The container 20 which can facilitate opening without damaging the sealability of the lid 30 during opening can be provided.SELECTED DRAWING: Figure 5
