A container including a neck portion leading to an outlet from the neck located outwardly thereof, the cross sectional area of the outlet being greater than the cross sectional area of the neck portion thereby providing a shoulder in the neck which in a pouring operation causes liquid flowing from the container to separate from an upper portion of the outlet and a duct communicating between the neck and the interior of the container whereby as liquid empties from the container in a pouring operation the resulting pressure differential arising between the interior of the container adjacent the inlet of the duct and the atomosphere draws air in an unimpeded manner into the container.

A container having pouring means for dispensing liquid, said means including: a neck portion of diminishing cross-sectional area leading to a peripheral channel of increasing cross-sectional area, said peripheral channel leading to an outlet having a greater cross-sectional area than the cross-sectional area of said neck portion said outlet being axially aligned with the neck but sufficiently larger in diameter so that, in a pouring operation liquid flowing from said container separates from an upper portion of said outlet, an air duct adjacent the upper portion of said outlet communicating with the upper portion of said container interior and of sufficient cross-sectional area throughout its length to maintain the interior of the container at substantially atmospheric pressure to maximize the rate of gulp-free dispensing of the liquid, said neck portion restricting liquid flow into the peripheral channel to maintain unimpeded air flow through said duct.
