ABSTRACT:
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.degree. to 15.degree. 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.
