FULLY VENTED WIDE RIM NURSING BOTTLE WITH CONTOURED VENT TUBE

摘要

A nursing bottle having a vent tube (113) that extends to vent pressure at all times. The vent tube extends distally from the vent insert (117), 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 (124) and minor seal (125) that prevents leaks out of the collar and onto an infant.
