PURPOSE: A leverage lid is provided to reduce the risk of conventional metallic lids for a bottle container, and to safely separate the lid from the container using the leverage principle. CONSTITUTION: A leverage lid uses the leverage principle for removing the compression applied to the lid when installing the lid to a bottle container. The leverage lid includes a leverage(2) extended from the lid, a bearing with the enough intensity and size for supporting the strength applied to the leverage, and a weakening portion(4) for weakening the compression of the lid.
