However, in the above conventional packaging container, in order to complete the fitting state of the lid to the container body, the engagement concave portion on the lid side is formed over the entire circumference of the lid body. Although the fitting state is complete, it is very difficult to remove the lid. In particular, this type of packaging container is formed using a thin material such as a synthetic resin sheet as described above, and the lid is made of a transparent sheet material so that the contents can be visually confirmed. For this reason, it is difficult to find a boundary portion between the container body and the lid body fitted to each other. Even if the boundary portion is found, it is difficult for an infant or an elderly person to put a finger between them, and as a result, it is difficult to remove the lid from the container body.
[0005]
Therefore, the present inventor has made various studies on how to eliminate the above-described difficulty in removing a packaging container comprising a container body of this type and a lid fitted to the container body. As a result of repeating the above, in short, it may be partial, so that it is sufficient to form an “opening” for opening, and the present invention has been completed.
