Sealing plug, characterized by comprising a rigid block of greater diameter than the neck, which in the sealing phase is located externally to the neck of the bottle to be sealed and from which part, attached to the same itself by partial housing therein, an elastic expansion frustoconical, prolonged, in turn, in a small portion of inverse conicity to the previous one to facilitate the forced introduction to the neck, which expansion, once introduced forcing it frontally towards the inside of the neck of the bottle, exerts sealing functions due to its natural expansion diametral, said plug comprising a small central hole that constantly maintains the atmospheric pressure inside the bottle.
