However, when the support piece (61) is overlapped and joined to the lower surface of the protruding piece (62), the upper surface of the two adjacent lid receiving pieces (57) and (58) is connected at the connecting portion by the joint. A step (65) is generated due to the thickness of the protruding piece (62). These lid receiving pieces (57) (58) (5
9) Since the upper surface of (60) is the joint surface with the lid,
If there is a step on the upper surface of the lid receiving pieces (57), (58), (59), and (60), a gap is created between the lid and the lid when the lid is welded and joined. Cannot be packaged in a sealed state.

That is, in a conventional packaging container in which a specific lid receiving piece is supported from below by a supporting piece provided at an end of an adjacent lid receiving piece, a lid receiving piece having a supporting piece is provided. On the upper surface of the adjacent lid receiving piece, a step is generated due to the paper thickness of the lid receiving piece, and the upper surface of the lid receiving piece having the support piece is lower than the upper surface of the adjacent lid receiving piece. When overlapping, a gap is generated between the lid and the lid receiving piece having the support piece, but in the packaging container of the present invention, the lid receiving piece having the support piece or the lid Since either one is provided with a ridge for eliminating steps,
Since the lid can be overlapped in a state where the step is eliminated, the article to be packaged can be packaged in a sealed state.
