Improvements in the opening and closing systems of containers, characterized essentially by the fact of comprising a previous phase of manufacturing a container by molding thermoplastic material, which is closed to heat, with glue or rubber obtained from this same material and a volatile solvent, resulting in a truncated cone-shaped container inverted in the lower three quarters, and externally threaded cylinder in the upper fourth, its upper base being formed by an annular rim, leaving the central plane of this base in depression, obtaining in the center of said base and in the operation of molding the whole, a slit or weakening of the thickness of the material, which is hidden under a spongy disk located in the mentioned depression and outstanding in its two thirds of thickness.
