A notch is provided at the rear end of the container body, and a connecting part is hung from the rear end of the lid into the notch to hinge-connect, and a through hole is vertically formed in the connecting part. A U-shaped synthetic resin spring material is attached to the through hole with the U-shaped bifurcated portion facing upward, and one of the U-shaped bifurcated portions of the spring material is attached to the lid body. The structure is such that one part is abutted and the other part is abutted against a part of the container body in a compressed state.

[0006]

[Action]

 That is, the compact of this invention has a connecting part hung from the rear end of the lid in a notch formed in the rear end of the container body and hinge-connected to a through hole vertically formed in the connecting part. A U-shaped synthetic resin spring material is attached with the U-shaped bifurcated portion facing upward, and one of the U-shaped bifurcated portions of the spring material is contacted with a part of the lid body. In addition, the other is pressed against a part of the container body in a compressed state. Therefore, in order to change from the closed state (the state in which the engaging portion provided on the front end portion of the container body is engaged with the engaging claw that is vertically provided on the front end portion of the lid body) to the open lid state, the above engagement is released. In this case, the bifurcated portion of the compressed spring material is extended, and this extension pushes the lid body toward the opening side and rotates it backward (that is, upward). For this reason, a gap is formed between the container body and the lid, and it becomes easy to lift the front surface or both left and right side surfaces of the lid with fingers. Moreover, the work of attaching the spring material to the lid can be performed simply by aligning the spring material with the lower end opening of the through hole formed in the connecting portion of the lid and pushing the spring material into the through hole as it is. Unlike the conventional example, it does not require fine movements of the hands, and automation is easy.
