<p>The present invention relates to a functional cap for fluid leak prevention that is disposed at the mouth of a container so as to prevent the leaking of a fluid out of a container. The functional cap for fluid leak prevention according to the present invention comprises: a main body that is disposed at the mouth of the container, has a fluid passage inside, and exposes the passage outside through an opened upper portion; a valve that is connected to the opened upper portion of the main body and is configured to control the discharge of the fluid by closing or opening the passage, a control rod being disposed so as to control the closing or opening of the passage; and a control ball that is placed at a position away from the control rod when the fluid is not poured and approaches the control rod when the container is tilted to pour the fluid so as to control the movement of the control rod. One of the control rod and the control ball is made of a magnet and the other is made of a magnetic body so that the control rod is moved by a magnetic force and the passage is opened in a case where the control ball approaches the control rod. According to the functional cap for fluid leak prevention of the present invention, the valve does not oscillate and the passage is not opened even in a case where the container is tilted by being dropped or falling and an impact is applied to the container and thus, there is no concern of an unintended fluid leak.</p> |
