Abstract:
1. A nursing bottle vent system comprising a flexible insert and a flexible capillary tube, the flexible insert in the shape of a wheel with a plurality of spokes, the outside diameter of the flexible insert the same as the outside diameter of the neck of a standard nursing bottle, the flexible insert possessing a cylindrical central housing at the center of the wheel shape, the central housing serving as the hub of the plurality of spokes of the wheel shape, the central housing possessing a cylindrical receptor coaxial with it, the cylindrical receptor and the plurality of spokes connected to each other, the plurality of spokes each possessing a longitudinal tunnel, each tunnel running the length of the spoke and connecting to an opening in the central housing and an opening in the outside of the insert, the flexible capillary tube a hollow tube with a tube tunnel, the diameter of the tube tunnel sufficiently small to create a capillary effect, the outside diameter of the flexible capillary tube the same as the inside diameter of the cylindrical receptor in the central housing, the flexible capillary tube capable of being inserted into the cylindrical receptor and being held in place by friction, the combination of flexible capillary tube inserted into central housing by means of placing within the cylindrical receptor providing a continuous passageway for air from the flexible capillary tube to the plurality of tunnels in the spokes of the flexible insert, the nursing bottle vent system assembled by connecting the flexible capillary tube to the cylindrical receptor in the central housing, placing the assembly of flexible capillary tube and central housing into a standard nursing bottle such flat the flexible capillary tube extends down into the nursing bottle and the flexible insert fits over the neck of the nursing bottle, placing a standard nursing bottle nipple over the flexible insert, and then screwing down a standard nursing bottle nipple cap over the nipple onto the nursing bottle neck, the nursing bottle vent system capable of maintaining equal air pressure between the outside air and the interior of the nursing bottle, the air pressure equalized by means of the continuous air passage from the interior of the bottle to the outside provided by the flexible capillary tube connection to the flexible insert and the plurality of tunnels within the spokes of the flexible insert.
