Pressure-rupturable plug for containers of different kinds, characterized by a hollow body with substantially thin walls, having a peripheral zone provided with a lateral cylindrical wall large enough to surround the neck of the container, with a central convex tea surrounded by said zone peripheral, extending from the outside, and with at least one line of weak resistance, diametrically extending from the edge of said side wall to the central convex said, so that a more or less sudden pressure exerted on said convex cap and tending to flatten it by deformation, causes the cap to break along the breakage, and, consequently, open.
