Overpressure valve, characterized by being constituted on the basis of a body that forms a central neck that traverses with ease a corresponding hole made in the lid or in the side wall of the container whose internal pressure is treated: to control, and two extreme sized heads of so that they can not pass through the indicated hole, limiting in both directions the possibilities of displacement of the expressed body with respect to it, completing the assembly with an elastic force acting on the head that is located to the outside, applying it constantly against the wall in which the orifice has been made, in which position the hermetic seal of the latter is made, until the internal overpressure, which acts in the opposite direction on said head, exceeds the force developed by the spring, and determines the axial displacement of the body and consequently the opening.
