PROBLEM TO BE SOLVED: To facilitate attachment and detachment of a lid body to and from a container body, and to stably hold the lid body in the opened state.SOLUTION: A plate portion 22 of the lid body 2 is fitted to a narrow portion 12 between protrusions 11 of the container body 1, and attachment/detachment to/from the container body 1 can be facilitated. A hinge part 21 is provided on the lid body 2, and thereby, the lid body can be freely opened and closed. When the lid body 2 is turned, the lid body abuts on the protrusion 11 of the container body 1, and when the lid body starts to fall backward, the plate portion 22 is pulled up by the lid body, and abuts on a narrow width part of the narrow portion 12, and is bent upward while having the contact point therebetween. By the elastic force of the plate portion 22 bending, the impact force caused by abutting of the plate portion to the narrow portion 12 is eased, and coming off from the narrow portion 12 or excess falling backward of the plate portion can be prevented. A plurality of protrusions 11 are provided on a surface of the plate portion 22, and rigidity of the plate portion can be adjusted in a well-balanced state. |
