A universal single piece venting insert for a container, the insert, when applied, holding a vent tube in position within the container, and extending in proximity with its interior bottom, the vent insert forming a cylindrical member, having an integral flange, the cylindrical member extends through the lid of the container, and the flange is otherwise adhered or held contiguously against the exterior of the lid, to function as a support for the venting structure. The interior of the venting insert, and more specifically its cylindrical member, has a series of communicating channels, a first tapered channel extending upwardly from its bottom, a second flaring portion extending further upwardly within the member, and the remainder being a cylinder forming the vent reservoir, where liquid may accumulate when the container is inverted during consumption of its fluids.
