PROBLEM TO BE SOLVED: To provide a chicken egg packaging container made of a plastic having insect preventive property which can be accurately and quickly fitted when a lid is placed. SOLUTION: A container main body (A) and a lid body (B) which have an approximately rectangular contour shape on the plane with each other are kept under a fitted state with a fitting protruding step surface (15a) and a fitting indented step surface (15b) which are extended into a rail configuration only along shorter edge edging flanges (2a) and (2b) being in parallel. Longer edge edging flanges (1a) and (1b) extended on an opening/closing hinge (3) side are simply kept under a state being in total surface-contact with each other on the butted surface (L-L). Then, on three edges, the other longer edge edging flange extended on a remaining free end side and both shorter edge edging flanges, a plurality of peripheral partitioning protruding walls (16a) and (16b) which are scattered are set to keep the partial fitted state. At the same time, longer edge edging flanges on the free end side are set to be sealed into a closely joined state with an adhesive tape (10). COPYRIGHT: (C)2004,JPO
