Claim:
A molded elastomer pour spout device comprising: an outer front flange panel having an upper region, an inner rear flange panel having an upper region, and an upper sector rim integrally joined to said front flange panel's upper region and to said rear flange panel's upper region while maintaining a predetermined distance and thereby forming a sector slot of predetermined width between said flange panels, said sector slot having its uppermost region bridged by said upper sector rim integrally joining the upper regions of said flange panels, leaving all other peripheral regions of said sector slot open, a shallow central spout protruding forward from said upper rim beyond said front flange panel, the upper rim and both flange panels being formed with a convexly curved shape, with both flange panels having radii of curvature about an axis perpendicular to the upper plane defined by the upper sector rim in said convexly curved shape, while maintaining said predetermined sector slot width, whereby said molded elastomer pour spout device is removably attachable to a sector of the rim of a liquid container vessel having a circular open upper vessel rim by lowering the elastomer pour spout's sector slot into sliding tractive telescoping engagement with said open upper vessel rim until said open upper vessel rim is substantially seated in contact with the uppermost region of said sector slot, where it is held by the flanges forming the slot being flexibly distorted to match the flanges, radii of curvature to those of the liquid container's open upper vessel rim, in cooperation with the tractive seated engagement of the outer flange and the inner flange resiliently telescoped over said open upper vessel rim, wherein said inner rear flange panel has a lower edge extending downward, with its lowest terminal lateral edge portions laterally spaced apart, leaving a higher central web portion between them.
