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.

A combination pouring spout and flat lid for attachment to the top of a viscous liquid container, comprising: (a) a short, conically-shaped pouring spout, of terminal length, made of a slightly yieldable material, 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; (b) a flange extending outward about said lower end of said spout containing means for absorbing shock from use of said spout and from extraneous impacts thereagainst, said means including a sinusoidal-shaped curved portion formed in said spout between said ringshaped portion and said mating surface; (c) an annular planar mating surface formed on the upper portion of said flange for contact with the underside of the flat lid; (d) a constricted throat portion formed in said spout opposite said mating surface of an outside diameter slightly less than the diameter of said aperture; (e) a swollen, ring-shaped portion formed in said spout above said throat of an outside diameter slightly greater than the diameter of said aperture, said swollen portion spaced above said mating surface a distance of at least the thickness of the lid; and, (f) an upwardly and inwardly slanted outer surface formed about said swollen, ring-shaped portion for centering said portion in said aperture and for yieldingly passing therethrough to bring said mating surface into contact with said lid and lock said spout firmly in said aperture.
