Definitions

  • the fully vented wide rim nursing bottle with contoured vent tube relates generally to infant serving products. More specifically, the present invention refers to nursing bottles having an internal tube that prevents a vacuum within the bottle and assists an infant to suck liquid from the bottle.
  • a unique aspect of the present invention is an expanding diameter of the venting tube that provides for its full venting during both usage and storage.
  • a nursing bottle features a silicone, latex, rubber or other material as a nipple with a hole in its tip secured across an opening in the top of the nursing bottle.
  • the current nursing bottle gets used by filling the bottle with a liquid, inserting the vent tube, securing the nipple, inverting the bottle, and placing the nipple into the baby's mouth and the baby takes it from there.
  • Vent tubes allow ambient air to enter the bottle generally behind the liquid while the baby suckles.
  • the vent tubes reduce any vacuum created by the suckling baby within the bottle.
  • the vent tube improves the flow of liquid out of the nipple and makes it easier for the baby to suckle. The baby faces less risk of sucking in air and the resulting colic.
  • Infant and infant feeding containers originally had a narrow superior orifice to which the nipple was attached. Caregivers noted that the narrow opening prevented ready access to the interior of the bottle and prevented easy cleaning of the interior of the bottle. Manufacturers then addressed that shortcoming with bottles having larger diameter openings. Those bottles met with sales success on the marketplace.
  • the larger diameter flanges prevented leaks where the nipples joined to the bottles.
  • nipples are designed for suckling to remove fluid from a bottle.
  • Nipples and other feeding accessories therefore have toughened designs to resist chewing. Chewing of nipples arises more often in infants with feeding problems, such as neurological delays or deficits. The neurological delays induce a frequent chewing motion by the infant upon objects placed in the mouth, often nipples.
  • Air introduced into the bottle may increase the pressure upon the interior of the bottle.
  • the increased pressure frequently forces liquid distally into a venting tube located within the bottle.
  • the liquid under pressure traverses the vent insert and the vent tube, exits the bottle, and causes liquid to spill from the bottle.
  • an air bubble trapped in a vent tube makes the liquid in the distal portion of the vent tube unable to traverse the vent tube and exit into the distal end of the bottle.
  • the liquid fails to enter the enlarged reservoir portion of the feeding tube for proper venting by the vent tube. Alas, feeding liquid may then impede the venting function of the tube.
  • venting and internal tubes prevent the formation of partial vacuums during suckling and resisted spills.
  • the '071 patent provides a vented tube extending into a bottle.
  • the vented tube has a hollow cylindrical shape projecting sufficiently downwardly into the bottle.
  • the '796 patent provides a reservoir located above a mark on the bottle. The reservoir communicates with a conduit system to replace suckled liquid with air from the reservoir thus preventing a partial vacuum in the bottle.
  • Nursing bottles of a multitude of designs are available in the prior art. In many instances, frequently a vacuum will be generated within the bottle during dispensing of its contents, as when nursing an infant.
  • a vacuum is believed to cause various physiological impairments to the infant when subjected to this type of condition.
  • the vacuum generated within the bottle due to the infant's sucking, can cause pressure imbalance at the location of various features of the body, such as in the ear canal, and which may lead to fluid, ear infection, speech delay, motor delay, developmental delay, illness, or other predicaments.
  • the presenting of a nursing bottle that incorporates air venting means, so as to prevent the creation of a vacuum inside the bottle has been considered a desirable development in the field of infant serving products.
  • the current invention provides means for venting of any air pressure within the bottle, and to prevent the generation of any vacuum or pressure therein, regardless whether the nursing bottle is being used, stored in an upright position, or partially or fully inverted as during consumption of its contents.
  • DE202004010113U1 (Tung Ling Ind Co [TW]) discloses a device for preventing reflux in baby feeding.
  • TW Tung Ling Ind Co
  • the receptacle has a pointed lower end and is screwed to the deflector element with its cup-shaped upper area.
  • the circular deflector has a hollow cylindrical shaft with radial attached bridges leading to the outer flange. The hollow bridges form reflux openings between them.
  • US2004/118801 A1 (Brown et al. [US]) discloses a nursing bottle, having a container comprising a wide rimmed opening for accommodating a collar, its supported nipple, a vent tube, and a vent insert.
  • the present art overcomes the limitations of the prior art -nipple vented bottles- where a need exists for reducing vacuum inside nursing bottles using vent tubes. That is, the art of the present invention, a tapering vent tube allows air to exit rapidly and distally from a tube and liquid to return promptly to a reservoir thus limiting the formation of a vacuum within a nursing bottle. The enlarged proximal portion of the vent tube minimizes the incidence of leakage from the bottle.
  • the present invention cleans easily, endures inadvertent chewing, and dissipates pressure generated by chewing. The present invention prevents leaks and continuously vents a bottle, thus dissipating any air bubbles in the vent tube.
  • the present invention as claimed improves the vent tube within a nursing bottle by changing the shape of the vent tube.
  • the vent tube has a contoured shape generally and preferably attains a conical shape with the diameter of the cone larger superiorly and smaller inferiorly.
  • the conical shape admits air distally into a bottle while immediately emptying liquid itself into the reservoir of the vent tube.
  • the conical shape prevents entry of liquid into an insert thus venting the bottle immediately and preventing leaks of liquid from the bottle.
  • the present invention provides an improved shape of the vent tube to lower internal pressures of liquids and air. Decreased transmission of pressure from nipple compression is noted at the widened proximal end of the vent tube.
  • the larger diameter of the conical shape prevents the liquid in the bottle from being propelled proximally into the tube of the insert and causing leaks. This is due to the larger diameter of the conical shape, at the proximal end of the tube as compared to the distal end, which dissipates the pressure of the compressed air and allows the liquid to gently flow into the reservoir. Preventing propulsion of liquid into the insert, the conical shape prevents leaks from the bottle.
  • the larger diameter of the conical shaped section increases the capacity of the reservoir. As the infant empties the bottle and the liquid level drops below the maximum, the liquid occupying the reservoir now, more rapidly and effectively exits the reservoir. When a caregiver or infant holds the bottle upright, liquid promptly exits the reservoir into the larger diameter of the conical shaped tube and returns the remaining liquid to the bottle.
  • the larger diameter of the vent tube is approximately 1.524cm (0.60 inches), and the narrow diameter of the vent tube is approximately 0.762cm (0.30 inches).
  • the container has a length from the bottom end to the rim at the top end of the container, and the aspect ratio between the length of the container and the inner diameter of the rim at the top end of the container (length/diameter) is less than about 3.0. Preferably still, the aspect ratio is less than about 2.80.
  • the present invention allows for instant and complete movement of any air bubble introduced by an infant chewing on a nipple to proceed to the distal end of the vent tube. Also, the present invention moves liquid -ahead of an air bubble- proximally into the reservoir of the vent tube.
  • the vent tube hereby functions in an automatic and continuous fashion as intended.
  • This invention establishes a structured relationship between the container or vessel and the formula within a nursing bottle.
  • the nursing bottle has sufficient size so that as the formula is prepared and deposited within the container, the formula's surface will be arranged below the vent port or the vent leading towards the exterior of the container, for venting purposes.
  • the concept of this invention is to provide a container with sufficient bulk and volume, so that the formula or milk as supplied therein, whether it be in the four ounce, six ounce, eight ounce, or any size category, will always leave the identified vent port exposed to attain the attributes of venting, for the nursing bottle, at all times.
  • the container may be shaped in a spherical form.
  • the container will be of a cylindrical shape, but be flattened on the sides.
  • the container may be of the jar shape, or even contain some concavity upon its sides, to facilitate its lifting.
  • the spherical or cylindrical type of container it may have a flattened bottom, to add stability to the nursing bottle, when rested upon a surface.
  • the venting port within the insert cooperates with a vent tube, and lateral vent slots, that are built into the insert that is secured to the top of the container by means of its associated threaded collar that holds the insert, the vent tube within the vessel, and the conventional nipple, in place.
  • the vent port within the insert associated with the vent tube may open directly and downwardly into the vessel, and it may have lateral ports to either side, so as to prevent the entrance of any formula, into the vent tube and allow venting as the container is being inverted during usage.
  • the container, collar, and nipple may be of the conventional type, but having the volumetric sizes from the shaped containers as previously explained, but the vent tube and port within the insert may extend through the surface of the container, rather than cooperate with the collar, in the manner as previously described in the '071 patent.
  • the orientation of the vent port, at its entrance point, leading to the vent tube can be arranged somewhere centrally of the configured container, regardless what shape or structures the containers may possess, so as to allow the formulation to either be below the vent port, or above it, as the nursing bottle is either at rest, or being inverted as during usage, in the manner as previously explained.
  • It is an even still further object of this invention is to provide for structured means within a nursing bottle that provides for continuous venting of any pressure or vacuum generated within its container, regardless of usage or nonusage of the subject bottle.
  • it is another object of this invention is to provide for the structure of a wide rimmed, or other size, collar for use with a standard wide mouth container as structured into a nursing bottle, and useful for feeding formula to an infant.
  • the present art overcomes the prior art limitations by providing a fully vented wide rim, or other size, nursing bottle that provides a tapering vent tube to eliminate vacuum within the container and prevent leakage from the container.
  • the fully vented, wide rim, or other size, nursing bottle preceding this invention is disclosed. It includes a spherical shaped container 1 that has ample volumetric capacity therein, so as to achieve the sought after results for this invention.

  • the formula may rise to the opposite side of the inverted container 1, but yet will have a surface level that will still be below the distal insert and its vent port 4, so that any sucking action generated by the infant, during feeding, and the formation of any vacuum, or partial thereof, within the container, during feeding, will be continuously vented by its vent port 4, through the vent tube 3, and out of the vent insert 7, as previously reviewed.
  • the container 1 of this invention will obviously include a minor flattened surface, as at 8, at its bottom, to allow the free standing of this nursing bottle, as when not in use, when stored, or when being warmed or heated in preparation for consumption of its formula contents.
  • Fig. 2A shows the container 1 and its nursing bottle when inverted, as during a feeding, to disclose how the fluid level 2 will yet remain below the opened vent port 4, so as to not obstruct the venting of any partial vacuum generated therein, during the feeding process.
  • Figs. 3 and 4 disclose a modification to the shape of the container 9 for the shown nursing bottle, with the further modification that the vent tube 10 will be integrally structured with the bottom 11 of the shown container, disposing its vent port generally centrally of the container, as can be noted at 12.

  • This nursing bottle is uniquely capable of reducing pressure increases within a vent tube and prevents leakage from the bottle.
  • This nursing bottle and its various components may be manufactured from many different materials including but not limited to polymers, low density polyethylene, high density polyethylene, polypropylene, glass, nylon, ferrous and non-ferrous metals, their alloys, and composites.
