A nursing bottle (1) formed of a large volume container, incorporating a vent tube (3) that extends inwardly of the container, having a vent port (4) arranged approximately at the volumetric midpoint (12) of the container, so as to allow for venting of pressure, whether of excessive or vacuum, to the atmosphere, at all times. The volumetric capacity of the nursing bottle container may be formed of a spherical shape (1), hemispherical shape (40), cylindrical shape (18), or to other configurations that provide for the internal volumetric capacity so that any formula placed therein will be prevented from blocking the vent port (4), the vent tube (3), regardless of the angular disposition undertaken by the nursing bottle during usage. The vent tube (10), with its disposed vent port (12), may either extend upwardly within the container, or extend downwardly (3) from its connection with the vent insert (7), operatively associated with a collar (6), that holds both the vent structures and the nipple (5) to the wide rimmed opening (19) for these type containers. In addition, as an alternative, the vent tube may be integrally formed, or connected by a flange, through the surface of the nursing bottle container, either at its bottom (14), or along a side (74), and either extend upwardly, or obliquely radially inwardly (82), so as to dispose its vent port (84) at that desired location approximately at the volumetric midpoint of the nursing bottle.

1. A wide-rim, fully vented nursing bottle adapted to be filled with liquid, wherein the bottle prevents a vacuum from being formed within the bottle when tilted or inverted during usage, and wherein the wide-rim of the bottle is facile of cleaning the bottle, the nursing bottle comprising: a container having a wide-rim at an open top, the wide-rim having a diameter slightly less than the width of the container, and the container being adapted to contain a quantity of liquid therein, the container having a volumetric capacity;a threaded collar, a nipple suitable for an infant feeding upon liquid from within said bottle, and a vent insert, said collar, said nipple and said vent insert cooperating and capable of application to the open top of the wide-rim container to provide venting to the interior of the nursing bottle when used, said vent insert provided for sealing upon the top of the wide-rim container and sealed therewith by the tightening of the threaded collar thereon, and said vent insert pressure fitting for sealing within the wide-rim of the container, an internal vent tube integrally extending downwardly from said vent insert, said vent insert having a lateral passage therethrough for venting to the atmosphere outside of said nipple between the threaded collar as applied to the container wide-rim, said vent insert further having a major lip and a minor lip, a vent receptacle portion adapted to be sealed to the vent insert and the minor lip, said internal vent tube having a lower end ending within said vent receptacle portion, a vent tube having an upper end integrally connecting with the vent receptacle portion and an opposite lower end terminating approximately at the bottom of said container such that when said container is maintained upright or inverted any liquid contained within the nursing bottle remains outside of said vent tube and below the bottom of said inverted integral vent tube within the vent receptacle portion;said threaded collar, vent insert, and vent receptacle providing a double seal within the wide-rim of the nursing bottle, said vent tube has an opening port in the vicinity of its distal lower end, and said vent tube having a generally tapered shape;an airway in the vent receptacle portion and through said internal vent tube and said vent insert and communicating the interior of the bottle to atmosphere when the nursing bottle is tilted or inverted during usage; andwherein the minor lip comprises a hollow cylindrical shape and the minor lip depends downwardly from the vent insert, said minor lip has a diameter, wherein the major lip comprises a hollow cylindrical shape and the major lip depends downwardly from the vent insert, the major lip has a diameter and the diameter of the major lip is greater than the diameter of the minor lip, the minor lip has a circumferential bulge on an exterior side of the minor lip with the bulge for receiving the vent receptacle portion for sealing the vent receptacle portion to the minor lip, and the major lip has a circumferential bulge on an exterior side of the major lip with the bulge for sealing the vent insert within an interior of the container. 2. The nursing bottle according to claim 1 wherein said collar, vent insert, and said internal vent tube are integrally structured. 3. The nursing bottle of claim 1 wherein said vent tube having a generally hollow contoured shape, a larger diameter of the contoured shape of said vent tube locating proximal to said reservoir, and a narrower diameter of the contoured shape of said vent tube locating distally from said reservoir and in proximity with the bottom end of said container, and said vent tube being centered upon said internal vent.
