A container produced of plastic material by blow-molding in a blow- molding device has an upper wall and a bottom connected to one another by a sidewall. A filling/pouring spout is located at the sidewall. The filling/pouring spout has an outer thread and a continuous circular sealing surface. A venting channel for providing a uniform, continuous outflow of a liquid contained in the container is provided. The venting channel is separated by a stay from the upper wall of the container. The stay is produced by squeezing edges of the blow-molding device. The venting channel has an inlet located within the filling/pouring spout. The upper end of the inlet is positioned at a level of the uppermost, continuous thread winding of the outer thread. The venting channel extends substantially horizontally above the upper wall in the form of a closed conduit from the inlet toward a portion of the sidewall opposite the filling/pouring spout into a vacuum space of the container in which, upon pouring of the liquid, a vacuum is created when no pressure compensation is provided. The venting channel has an underside extending downwardly at an angle of 2 to 15 relative to the horizontal. The thread windings of the outer thread below the uppermost thread winding have discontinuities resulting from the squeezing edges of the blow-molding device for forming the stay. Portions of the thread windings extend across the backside of the inlet of the venting channel between the discontinuities.
