A container stopper essentially characterized in that it has a body of plastic material, threaded to receive a plug which can be inserted into an opening in the wall of a metal container and which has, for sealing against said wall, a flange made by molding and a peripheral bored circular rim, provided internally with a ring that establishes a rigid reinforcement that maintains this rim in its shape, the annular edge of said opening of said wall being tight between this rim and the flange, the aforementioned body having a bottom closing the shutter and is intended to be torn when the shutter is to be opened, characterized in that this separable bottom has in its peripheral region an annular part in the form of a bellows, to limit the amplitude of the stresses in said bottom, due to temperature variations, thanks to the deformation of such an annular part.
