ABSTRACT:
A container for dispensing a fluid with no contraction/expansion “glug, glug” effect has a cover forming a sealed top with a pouring spout on top of the cover and at least one elongated handle on top of the cover. The elongated handle extends longitudinally away from the pouring spout and has a distant end coupled to a vacuum manifold formed under the cover as a void space distant from the pouring spout and above fluid within the fluid tight container. A pouring spout has a circular aperture leading into the fluid tight container. The circular aperture has a central axis; the circular aperture is bordered by a peripheral circular sealing surface that extends radially away from the aperture. An air vent opening is positioned on the circular aperture's highest radial central position on the circular sealing surface. A dual air vent bypass channel delivers air entering the air vent opening via a top channel through the elongated handle to the vacuum manifold, and via a bottom channel under the cover to the vacuum manifold.
