A nursing bottle formed of a container, incorporates a reservoir and venting tube that eliminates vacuum. The nursing bottle has a cylindrical shape or other configuration that prevents formula therein from blocking the venting tube when held at any angle. The venting tube extends distally from the insert and alternatively may be in separate pieces. The insert has a flange on its perimeter, extending inferiorly and securing the insert to the superior and lateral aspects of the neck of the container. The vent opens at the volumetric center of the reservoir above the conically shaped venting tube depending from the reservoir, where the venting tube has a conical shape of decreasing diameter.
