On the other hand, since the second lid fitting portion 160 of the lid 100 is provided on the upper portion 141 side of the lid flange portion 140, when the lid 100 is directly attached to the container body 300 as shown in FIG. 5, the container main body 300, the inner plate 200 and the lid 100 do not have a three-layered portion, so that the lid 100 can be deeply covered over the container main body 300 to the innermost side and tightly externally fitted. Therefore, it is difficult for dust and the like to enter the inside of the container main body 300, and high airtightness is provided.

Furthermore, since the container body 300 of the packaging container 400 of the present invention is made of paper and has an outwardly curved curled portion 340 on the periphery of the opening, the curled portion 340 is formed between the lid body 100 and the inner plate 200. It can be used as a fitting portion for external fitting. In particular, when the container body 300 of the present invention is made of paper, if the curled portion 340 that curves outward is provided on the periphery of the opening, the fitting between the lid 100 and the inner plate 200 will occur inside the periphery of the opening. It is difficult to establish a spot. Therefore, in the present invention, the curled portion 340 is effectively used as a fitting portion between the lid 100 and the inner plate 200 .

The packaging container of the present invention is not limited to the above examples, and various modifications and combinations are possible within the scope of the claims and the scope of the embodiments. , the combination is also included in the scope of the right.
