PROBLEM TO BE SOLVED: To improve reliability and sealability held in a closed state by providing a protrusion on a hinge for connecting a lid and a container body which are made of a thin synthetic resin and forming, on an upper part of a peripheral wall of the container body, a shelf with which a summit of the protrusion formed outside an opening periphery of the lid comes into contact when the container is closed. SOLUTION: The fitting package container comprising lid 1 and a container body 2 which are connected via a hinge 3 has a protrusion 12 provided along a periphery of an opening 11 of the lid 1 and an outer peripheral wall 121 extended along an outer periphery of the protrusion 12. A flange 13 is provided at an end rim of the outer peripheral wall 121, while a flange 23 is provided along a periphery 21 the container body 2. An upper part of a peripheral wall 24 of the container body 2 is made to protrude outward from the body 1, while a lower part of the peripheral wall 24 of the body 2 is recessed inside the body 2 to provide a swell inside the body 2. An upper face of the swell is formed to be approximately in parallel to a bottom face of the container body 2, thereby providing its upper face as a shelf 242. The hinge 3 makes a protrusion 35 protrude at a tip which is a center line in a long axial line direction of a center strip. |
