A vent prevents a vacuum from forming within an inverted container of liquid when the liquid is dispensed. The vent is a double vent, formed of a vent tube, upon which a reservoir and its integral vent tube locate, the reservoir securing with the vent tube that extends through the reservoir upper surface, to achieve the double venting of the interior of the container. The container is a nursing bottle, with a collar and nipple applied to the top, and the vent tube being integrally formed extending downwardly from the collar, and securing the reservoir and its integral tube thereon, when assembled for usage. The bottle may be formed of a transparent material, tinted to one coloration, while the reservoir and its reservoir tube may be tinted to a different coloration, which when they are assembled, exhibits a third coloration for the reservoir tube when viewed from exteriorly of the tinted nursing bottle during its application.
