ABSTRACT:
A combination pouring spout and flat lid for attachment to the top of a viscous liquid container, including a short, conically-shaped pouring spout having a narrow diameter upper end and a wider diameter lower end allowing it to pass upward through an aperture formed in the flat lid for fixable engagement therewith, a flange extending outward about the lower end of the spout containing construction for absorbing shock from use of the spout and from extraneous impacts thereagainst, an annular planar mating surface formed on the upper portion of the flange for contact with the underside of the lid, a constricted throat portion formed in the spout having a swollen, ring-shaped portion formed in the spout above the throat of an outside diameter slightly greater than the diameter of the aperture and an upwardly and inwardly slanted outer surface formed about the ring-shaped portion for centering the ring-shaped portion in the aperture to bring the mating surface into contact with the lid and lock the spout firmly in the aperture.
