PURPOSE:To prevent a lid from opening from a main body by providing locking holes on one of the main body and the lid and providing, on the other, locking bodies which are in contact with two or more locking holes for expanding the locking holes. CONSTITUTION:A container body 1 and a lid 2 are integrally formed of a thin synthetic resin material, wherein the lid 2 is made to freely open/close by bending a coupling 3 between them. Locking holes 4 are provided on a flange 1a of the container body 1 provided on a side rim facing the coupling 3, and locking bodies 5 which are in contact with two or more of the locking holes 4 for pressing the holes 4 to expand them are provided on a flange 2a of the lid 2. When the lid 2 is closed and the locking bodies 5 are fitted into the locking holes 4, the locking holes 4 are expanded and the locking bodies are pushed back at contact positions between the holes 4 and the bodies 5, so that they are forced to be fitted with each other with both deformed slightly. Therefore they are difficult to be disengaged, and the lid 2 can be prevented from opening from the container body 1, thereby improving operativity and preventing the lid 2 from naturally opening. |
