The present invention relates to a safety lid, the main configuration of the present invention is coupled to the inlet of the container containing the contents, in the safety lid consisting of the inner lid and the outer lid, the inner lid is a protrusion projecting upward on the upper side ; A plurality of locking hooks receiving rotational force only in the locking direction on the outer circumferential upper portion of the protrusion; A plurality of opening hooks which receive rotational force only in the opening direction at the lower periphery of the protrusion; And, a water inclined surface protruding to the lower outer periphery, the outer diameter is wider toward the lower; It comprises, and the outer lid, extending downward from the inner upper, having an inner circumference corresponding to the outer circumference of the protrusion, and in contact with the locking hook normally and apply a rotational force only in the locking direction, and lowered by an external force A plurality of operating pieces that contact with the opening hooks to apply rotational force in the opening direction; An inclined surface having an inner diameter widened downward to correspond to a water inclined surface of the inner lid at an inner lower portion thereof; And a locking part formed to protrude inwardly at an inner lower end to contact a lower portion of the water inclined surface of the inner lid and to maintain a coupling between the inner lid and the outer lid. Characterized in that comprises a. Therefore, the present invention, the operation piece of the outer lid is normally in contact with the locking hook to apply a rotational force only in the locking direction, thereby preventing the safety lid to be opened arbitrarily to prevent the leakage of unnecessary contents, thereby the contents as well as possible There is an effect that can be utilized.
