PROBLEM TO BE SOLVED: To prevent troubles in handling and wrapping by a method wherein tabs for releasing the state of internal fitting for a lid body are formed integral ly at a part of the outer periphery of the lid body and dents for accepting respectively the entire body of each of the tabs are formed at a flange of a container main body. SOLUTION: Each of dents 13 for accepting each of tabs 30 of a lid body 20 formed respectively at flange parts 11 constituting both of long sides of a packaging container at positions punctually symmetrical to the center of the packaging container comprises gentle slopes 13c on the right and left smoothly extending from the upside of each of the flange parts 11 and a horizontal bottom face 13a placed between both of the gentle slopes 13c at a position lower than the flange part 11. Thereby, when the lid body 20 is fitted internally into a container main body 10, each of the tabs 30 formed integrally at the lid body is positioned at the horizontal bottom face 13a, being guided by each of the slopes 13c. Then, each of the tabs 30 is completely accepted into each of the dents 13, being mounted on each of the horizontal bottom faces 13a.
