In a closure device with pouring nozzle and metering stopper, the pouring nozzle is formed of a pouring spout of closed periphery, extending partly inside a sheath and protruding beyond the sheath. The sheath is in turn extended by a rotating ring provided for its fixation and orientation on end of a neck of the container and having its outer wall serving for retaining a skirt formed about a lower portion of a body of the metering stopper with a pouring spout forming a cover and covering the pouring spout of the pouting nozzle.
