ABSTRACT:
The baby bottle according to the invention has an opening in the base of the bottle. A spring loaded valve is positioned in the opening and cooperates with an O-ring seal on the base. The valve includes a body having a pair of innerconnected, T-shaped channels forming the air inlet. The valve is further recessed in the bottom of the bottle to avoid inadvertent opening or breaking of the valve if the bottle is dropped.
