A nursing bottle formed of a small volume container, incorporating a venting tube that extends to dissipate pressure at all times. The nursing bottle may have a cylindrical shape or other configuration that prevents formula placed therein from blocking the venting tube when held at any angle. The venting tube extends distally from the insert portion, operatively associated with a collar that holds the vent structures and the nipple to the neck of the container. The vent opens at the volumetric center of the reservoir above the venting tube. Alternatively, the venting 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.

1. A nursing bottle assembly having a container with a closed bottom end, a top end opposite said bottom end and having an opening therein for receiving liquid into an interior of the container, a rim at the top end also with an inner diameter defining the size of the opening at the top end, a nipple, and a threaded collar to provide sealing between said nipple and said top end while allowing liquid to flow from said container to said nipple, and to provide closure for the opening at the top end, wherein the improvement comprises: a single piece insert generally providing venting to said bottle assembly, having an integral insert portion, an integral vent depending from the center of said insert portion, an integral reservoir depending from the center of said insert portion with said vent within said reservoir, and an integral venting tube in communication with said reservoir and depending from said reservoir;said insert portion sealing to said top end and having a horizontal aperture therethrough for communicating with the inner space of said container;said vent being in communication with said horizontal aperture and having a length approximately one half that of said reservoir;said venting tube having a distal end disposed proximate the bottom of said container and being open to the inner space of the container to facilitate venting;said reservoir having a generally hollow cylindrical shape with an upper end joined below said insert portion and an opposite lower end;said vent having a constant diameter and a distal end, and being generally perpendicular to said insert portion; andan inner space of said reservoir having a volumetric capacity and a volumetric center, and said distal end of said vent generally opening near the volumetric center of said reservoir. 2. The nursing bottle assembly of claim 1 further comprising: said venting tube having a constant diameter. 3. The nursing bottle assembly of claim 1 further comprising: said venting tube having a conical shape with a larger diameter proximally towards said reservoir and a narrow diameter distally. 4. The nursing bottle assembly of claim 3 wherein said larger diameter of said venting tube is no more than the diameter of said reservoir and exceeds the diameter of said vent. 5. The nursing bottle assembly of claim 1 further comprising: a gasket, locating upon said rim and below said single piece insert. 6. A container for dispensing fluids during nursing having a closed bottom end, a top end having an opening therein for receiving liquid into the interior of the container, a rim at the top end also with an inner diameter defining the size of the opening, a threaded collar, a nipple, and said container having a volume suitable for a premature infant, comprising: a single piece insert to generally close and to ventilate the inner space of the container during usage, said insert sealing to said top end, and having an integral insert portion, an integral vent depending from said insert portion with a distal end disposed generally perpendicular to said insert portion and within the inner space of the container, an integral reservoir disposed outwardly from said vent, generally coaxial and depending from said insert portion, and an integral venting tube depending from said reservoir;said insert portion having a horizontal aperture for communicating through said vent to the inner space of said container;said venting tube having a constant diameter and an end away from said reservoir, said end locating proximate the bottom of said container and being open to the inner space of said container;said reservoir having a cylindrical shape, an upper end joined to said insert portion, and a lower end in communication with said venting tube;an inner space of said reservoir having a volumetric capacity and a volumetric center;said vent having a length approximately half that of said reservoir and the end of said vent being disposed generally near the volumetric center;said insert portion having a generally annular shape and a rib extending diametrically across said insert portion;said horizontal aperture extending through said rib and approximate the center of said rib communicating with said vent; andsaid rib widening in the vicinity of the center to receive said upper end of said reservoir. 7. A container for dispensing fluids during nursing having a closed bottom end, a top end having an opening therein for receiving liquid into the interior of the container, a rim at the top end also with an inner diameter defining the size of the opening, a threaded collar, a nipple, and said container having a volume suitable for feeding an infant, comprising: a single piece insert to generally close and to ventilate the inner space of the container during usage, said insert sealing to the top end, and having an integral insert portion, an integral vent depending from said insert portion with a distal end disposed generally perpendicular to said insert portion and within the inner space of the container, an integral reservoir disposed outwardly from said vent, generally coaxial and depending from said insert portion, and an integral venting tube depending from said reservoir;said insert portion having a horizontal aperture for communicating through said vent to the inner space of said container;said venting tube having a conical shape, a larger diameter proximally and a narrow diameter distally and disposed generally near the bottom of said container and being open to the inner space of said container;said reservoir having a cylindrical shape, an upper end joined to said insert portion, and a lower end in communication with said venting tube;an inner space of said reservoir having a volumetric capacity and a volumetric center;said insert portion having a generally annular shape and a rib extending diametrically across said insert portion;said horizontal aperture extending through said rib and proximate the center of said rib communicating with said vent; andsaid rib widening in the vicinity of the center to receive said upper end of said reservoir. 8. The nursing bottle assembly of claim 7 further comprising: a gasket, locating upon said rim and below said single piece insert. 9. The container for dispensing fluids of claim 7 wherein said larger diameter of said venting tube is no more than the diameter of said reservoir and exceeds the diameter of said vent.
