PROBLEM TO BE SOLVED: To facilitate attachment and detachment of the lid of a packaging container designed, for example, for take-out use, ensure fitting of the lid, and hinder condensation on the rear of the lid. SOLUTION: Rectangular annular flange 4 is formed around an opening 2 defined at the top of a container main body 1. The four corners 6 of the lid 3 for covering the opening 2 at the top are bent down along creases 7 in a manner of chamfering the corners. The lid 3 is locked over the container main body 1 by allowing the corners 4a of the flange 4 of the container main body 1 to stick out through slits 8 formed along the creases 7. The lid 3 is formed from a corrugated board. Thus, selling date and time, etc., can be directly printed on the surface. Moisture absorbent paper is used as a liner for the rear of the corrugated board in order to absorb condensation. |
