Abstract
A nursing bottle formed of a large volume container, incorporating a vent tube that extends to vent pressure at all times. The nursing bottle may have a cylindrical shape or other configuration that prevents formula placed therein from blocking the vent tube regardless of its angular disposition. The vent tube extends distally from the vent insert, operatively associated with a collar, that holds the vent structures and the nipple to the wide rimmed opening. In addition, the vent tube has a conical shape of decreasing diameter distally toward the center of the bottom to dissipate the pressure that may cause leakage from the bottle. Further, the vent insert has a major and minor seal that prevents leaks out of the collar and onto an infant.
