PROBLEM TO BE SOLVED: To allow a lid to be opened by easy operation from a fitting state between a container body and the lid.SOLUTION: A container body includes a flange part which projects from an outer peripheral surface of a mouth and is a guide surface widening downward. A lid includes a lid body formed by a guide hole vertically penetrating an outer peripheral part of the lid body closing the mouth and a claw piece whose claw part fitted below the flange part protrudes inward at a lower part of a claw support piece part projecting downward from the lid body outside the guide hole. In order to open the lid, a press lid includes a press lid body which is arranged apart above the lid body, can lower when moving forth, and can rise when moving back with respect to the lid body, and a press piece which protrudes from the press lid body to a guide surface via the guide hole. A gap between the claw support piece part and the guide surface becomes narrow as it goes downward, and the press piece arranged in the gap elastically deforms the claw support piece part so as to cancel the fitting between the flange part and the claw part as it lowers along the guide surface, and presses and spreads it outward. |
