DESCRIPTION

Fully ventilated wide flange bottle with contoured vent tube Technical field

The fully ventilated wide flange bottle with contoured ventilation tube refers, in general, to products for serving infants. More specifically, the present invention relates to bottles that have an internal tube that prevents a ford into the bottle and assists an infant to suck liquid from the bottle.

Prior art

A unique aspect of the present invention is an expansion diameter of the ventilation tube that provides full ventilation during both use and storage.

Infants have the instinct to breastfeed their mothers' milk. For a variety of reasons, however, infants often drink fluids from other sources. Infants do not have the ability to drink from normal glasses and cups without spilling them. Thus, liquids are fed to infants using bottles for infants or bottles. A bottle has silicone, latex, rubber or other material such as a nipple with a hole in its end secured through an opening in the top of the bottle. In the current bottle it is customary to fill the bottle with a liquid, inserting the ventilation tube, securing the nipple, inverting the bottle, and placing the nipple in the infant's mouth and the infant takes from there

The bottles, vented on the flange of the nipple, are tightly closed, except for the opening in the nipple. As the infant is fed, the volume of liquid in the bottle decreases and the ford in the bottle increases proportionally thus contaminating the liquid. However, the ventilation tubes allow ambient air to enter the bottle usually behind the liquid, while the infant is breastfeeding. The ventilation tubes reduce any vacuum created by the infant inside the bottle. The ventilation tube improves the flow of liquid from the nipple and makes it easier for the suckling infant. The infant faces a lower risk of aspirating air and resulting colic.

The infant and infant feeding vessels originally fear a narrow upper hole to which the nipple was attached. Doctors noted that the narrow opening prevented easy access to the inside of the bottle and prevented easy cleaning of the inside of the bottle. The manufacturers then addressed that deficiency with bottles that fear openings of greater diameter. These bottles presented a successful sales in the market.

The larger openings called for the manufacture and use of teats and feeding mouths with flanges of greater diameter to coincide with the opening of the bottle. The larger diameter flanges prevent leaks where the teats are attached to the bottles. However, the larger diameter teats, maintaining the same distance from the upper end to the lower end of the nipple, fear a greater volume contained by the teats.

In addition, infants often chew the teats although the teats are designed for infants to extract liquid from a bottle. The teats and other feeding accessories, therefore, have hardened their designs to resist chewing. The chewing of the teats occurs more frequently in infants with feeding problems, such as delays or neurological deficiencies. Neurological delays induce a frequent chewing movement by the infant over objects placed in the mouth, often teats.

During frequent chewing of the feeding nipple, especially those with larger diameters and internal volumes, the infant drives air distally in the bottle itself. The air introduced into the bottle can increase the pressure inside the bottle. The increase in pressure often distally forces the liquid into a vent tube located inside the bottle. The liquid under pressure passes through the ventilation insert and the ventilation tube, leaves the bottle, and causes the liquid to spill from the bottle.

Leaks from chewing also arise when the introduced air stops midway inside a cylindrical ventilation tube. Due to the pressures inside the cylindrical ventilation tube, some liquid can be trapped in the ventilation tube by an air bubble caused by the chewing of the infant. The air bubble should be forced out, ideally when it normally enters the tube when the bottle is inverted and in a feeding position for the infant.

However, an air bubble trapped in a vent tube makes the liquid in the distal portion of the vent tube unable to pass through the vent tube and out at the distal end of the bottle. The liquid cannot enter the enlarged reservoir portion of the feed tube for adequate ventilation by the vent tube. Unfortunately, the feed liquid can then impede the ventilation function of the tube.

Many attempts have been made to provide a bottle with an air outlet to reduce the creation of a ford during suction. An earlier Roderick patent, No. 598,231 has a bottle with a U-shaped tube. However, the average infant, when raising a bottle, has some liquid retained in the U-shaped tube. The retained liquid blocks the tube and prevents ambient air from releasing any ford inside the bottle. Other

Patents show related types of technology, and provide means to vent the air from inside a container, as can be seen in US Patent for Van Cleave, No. 927.013. In addition, the Davenport patents, No. 1,441,623 and Perry, No. 2,061,477, show other means of venting the air from inside a bottle.

In the previous work of these applicants, patents Nos. 5,779,071 and 5,570,796, ventilation and internal tubes prevent the formation of partial fords during lactation and resist spillage. The patent

5,779,071 provides a vent tube that extends into a bottle. The vent tube has a hollow cylindrical shape that projects sufficiently down into the bottle. Patent 5,570,796 provides a deposit located above a mark on the bottle. The reservoir communicates with a duct system to replace the liquid lacto with air from the reservoir thus avoiding a partial ford in the bottle. Bottles of a multitude of designs are available in the prior art. In many cases, the ford is often generated inside the bottle during dispensing of its contents, such as when an infant is breastfed. It is believed that a ford causes various physiological alterations to the infant when they undergo this type of condition. The ford generated inside the bottle, due to the sucking of the infant, can cause imbalance of pressure in the location of the various features of the body, such as in the ear canal, and that can lead to infection of the fluid of the finger, delay in the speech, motor retardation, developmental delay, illness, or other predicaments. Therefore, the presentation of a bottle incorporating air ventilation means, in order to avoid the creation of a ford inside the bottle, has been considered a desirable development in the field of children's products. This can be seen in the previous patents of applicants 5,779,071 and 5,570,796, wherein the reservoir tube that provides ventilation, outside the bottle cap in a close proximity, extends at the bottom of the container, so that it works as ventilation while the contents of the bottle are being consumed, when partially or totally reversed.

The present invention, on the other hand, provides means for the ventilation of any air pressure inside the bottle, and to prevent the generation of any ford or pressure therein, regardless of whether the bottle is being used, stored in a position. vertical, or partially or totally inverted, such as during the consumption of its contents.

Other US patents that relate to the subject matter of the present invention include US Pat. de Briere, No. 189,691; U.S. Patent No. 345,518, of Lelievre; U.S. Patent No. 679,144, of Hardesty; U.S. Patent No. 834,014, of Lyke; U.S. Patent No. 1,600,804 of Donaldson; US patents No. 2,156,313, and No. 2,239,275 to Schwab; US patent No. 2,610,755, of Gits; No. 2,742,168, of Panetti; U.S. Patent No. 2,744,696, of Blackstone; U.S. Patent No. 3,059,707, of Wilkinson, et al .; U.S. Patent No. 5,570,796, of Brown, et al. In addition, British patents No. 273,185 and No. 454,053 show related developments.

Document DE202004010113U1 (Tung Ling Ind Co [TW]) discloses a device for the prevention of reflux in infant feeding. When the infant releases the nipple, bubbles enter the interior space of the bottle. They are guided through openings to a baffle element in a bubble collection element and are prevented from returning to the exit when the infant takes the next sip. The receptacle has a pointed bottom end and is screwed to the deflector element with its top cup-shaped area. The circular baffle has a hollow cylindrical shaft with attached radial bridges leading to the outer flange. Hollow bridges form reflux openings between them.

Document US2004 / 118801 A1 (Brown et al. [USA]) discloses a bottle, which has a container comprising a wide beaded opening for housing a collar, its supported nipple, a ventilation tube, and a ventilation insert.

The current technique overcomes the limitations of the prior art - ventilated teat bottles - where there is a need to reduce the ford inside the bottles using ventilation tubes. That is, the technique of the present invention, a narrowing vent tube allows the air to flow quickly and distally from a tube and the liquid quickly returns to a reservoir thus limiting the formation of a ford within a bottle. The enlarged proximal portion of the ventilation tube minimizes the incidence of bottle leakage. The present invention is easily cleaned, overcomes involuntary chewing, and dissipates the pressure generated by chewing. The present invention prevents leaks and continuously vents a bottle, thus dissipating air bubbles in the ventilation tube.

Summary of the invention

Accordingly, the present invention as claimed improves the ventilation tube within a bottle by changing the shape of the ventilation tube. The ventilation tube has a general contoured shape and preferably reaches a conical shape with the diameter of the largest cone at the top and smaller at the bottom. The conical shape admits air distally in a bottle, while the liquid immediately flushes into the reservoir of the ventilation tube. The conical shape prevents liquid from entering an insert thereby ventilating the bottle immediately and preventing liquid leaks from the bottle.

Additionally, the present invention provides an improved form of the vent tube to reduce internal pressures of liquids and air. The decrease in the transmission of the compression pressure of the nipple is observed at the enlarged proximal end of the vent tube. When pressure is exerted on the milk in the bottle, and it rises in the ventilation tube, the milk loses its strength due to the widening characteristics of the ventilation tube when reaching its wider upper part. The larger diameter of the conical shape prevents liquid in the bottle from being propelled proximally into the insertion tube and causing leaks. This is because the larger diameter of the conical shape, at the proximal end of the tube compared to the distal end, dissipates the pressure of the compressed air and allows the liquid to flow smoothly into the reservoir. By preventing liquid propulsion in the insert, the conical shape prevents leakage from the bottle.

In addition, the larger diameter of the conical section increases the capacity of the tank. As the infant empties the bottle and the liquid level drops below the maximum, the liquid that occupies the tank now, comes out more quickly and efficiently from the tank. When a caregiver or an infant holds the bottle in an upright position, the liquid quickly comes out of the reservoir into the largest diameter of the tube conically and returns the remaining liquid to the bottle.

Preferably, the largest diameter of the ventilation tube is approximately 1,524 cm, and the narrow diameter of the ventilation tube is approximately 0,762 cm. Also, in a preferred embodiment, the container has a length from the lower end to the flange at the upper end of the container, and the relationship of dimensions between the length of the container and the inside diameter of the flange at the upper end of the container (length / diameter) is less than about 3.0. Preferably still, the ratio of dimensions is less than about 2.80.

The present invention allows the instant and complete movement of any air bubble introduced by a child chew on a nipple to proceed to the distal end of the ventilation tube. In addition, the present invention moves the liquid - ahead of an air bubble - proximally in the reservoir of the ventilation tube. The ventilation tube works like this in an automatic and continuous way as planned.

The present invention establishes a structured relationship between the container or container and formulates it in a bottle. The bottle has a sufficient size so that the formula is prepared and deposited inside the container, the surface of the formula will be arranged below the ventilation hole or the ventilation port that leads to the outside of the container, for ventilation purposes . Furthermore, even when the container is inverted, by the infant or the caregiver, during feeding, the liquid formula will still not approach the ventilation of the distal insert in any position. Therefore, the concept of the present invention is to provide a container with sufficient mass and volume, so that the formula or milk as supplied therein, whether in 113.40 g, 170.10 g, 226 , 80 g, or any size category, will always leave the identified ventilation port exposed to reach the ventilation attributes, for the bottle, at all times.

Therefore, no appreciable positive or negative pressure will build up in the ventilation port, since the ventilation port will open, with the escape purposes, when the bottle is held in a vertical direction, such as while it is warming or heats, during the preparation for a feed, and even while the bottle can be reversed, as during a feed, as well as to allow the ventilation of any negative pressure, generated internally inside the container, which can occur as a result of the suction action of the infant.

This feature of providing sufficient internal volumetric size to the container is achieved by using containers that are of excessive dimensions, such as being large and spherically shaped, or cylindrical and flattened on each surface, or having a size equivalent to from a Mason jar. In one case, the container may be shaped in a spherical shape. In another embodiment, the container will be cylindrical in shape, but flattened on the sides. In a further embodiment, the container can be in the form of a bottle, or even contain some concavity on its sides, to facilitate its elevation. In addition, when the type of spherical or cylindrical container is used, it can have a flattened bottom, to add stability to the bottle, when resting on a surface.

In the preferred embodiment, the ventilation port within the insert cooperates with a ventilation tube, and lateral ventilation slots, which are integrated in the insert that is fixed to the top of the container by means of its associated threaded collar which It contains the insert, the vent tube inside the container, and the conventional nipple, instead. The ventilation port inside the insert associated with the ventilation tube can be opened directly and downwards in the container, and can have side ports on each side, in order to prevent the entry of any formula, into the ventilation tube and allow the ventilation when the container is being inverted during use.

In a further embodiment, the container, the neck, and the nipple may be of the conventional type, but with the volumetric sizes of the containers formed as explained above, but the ventilation tube and the port within the insertion may extend to through the surface of the container, instead of cooperating with the collar, in the manner as previously described in patent 5,779,071.

However, the orientation of the ventilation port, at its point of entry, which leads to the ventilation tube, may be arranged somewhere in the center of the configured container, regardless of what shape or structures the containers may possess, so that allow the formulation to be either below the ventilation hole, or above it, when the bottle is either at rest, or inverted as during use, in the manner as explained above.

Therefore, it is an object of the invention is to provide a new and improved ventilation tube for baby bottles.

It is a further object of the present invention to dissipate the pressure on the liquid with a bottle, preventing the introduction of liquid into the insert, thus stopping leaks.

It is a further object of the present invention to provide an immediate exit of air bubbles when a bottle is inverted.

It is a further object of the present invention to provide an apparent increase in volume of the receptacle caused by the larger diameter of the conical shape thereby immediately emptying the liquid from the receptacle.

It is a further object of the present invention to provide a volumetric size container for use as a bottle, and incorporating a vent tube with an insert that is disposed approximately in the center thereof, such that the vent hole within the insert avoids the coverage of any formula or milk contained in it, either during use when the infant is fed, or during non-use when the bottle has been fixed on its base, such as during storage, while it is heated, or When it is at rest.

It is a still further object of the present invention to provide structured means within a bottle that provide continuous ventilation of any pressure or vacuum generated within its container, regardless of the use or non-use of said bottle.

Finally, it is another object of the present invention to provide the structure of a broad flange collar, or of another size, for use with a standard wide-mouth container structured in a bottle, and useful for feeding the formula to a infant

These and other objects may become more apparent to those skilled in the art after reviewing the invention as described herein, and on conducting a study of the description of their preferred embodiment, when viewed in conjunction with the drawings. .

Best way to carry out the invention

The present technique overcomes the limitations of the prior art by providing a fully ventilated wide flange bottle, or of another size, which provides a narrowing vent tube to eliminate the vacuum inside the container and prevent leakage from the container. With reference to the drawings, and in particular figures 1 and 2, the fully ventilated, wide-edged or other size bottle is disclosed prior to the present invention. It includes a spherical container 1 that has a large volumetric capacity therein, in order to achieve the results sought for the present invention. That is, when a formula, such as in 2, is applied in the container, with the formula being applied in an amount that normally provides a feeding for the infant, it will only fill the container to a level that is still below the bottom of the ventilation tube 3, and more specifically distal to the insert and its ventilation port 4, as can be seen.

Therefore, when the bottle is heated, and if any pressure builds up in its container, it will be

immediately vented to the atmosphere, due to the opening of the vent port 4 of the distal insert, to absorb any pressure generated, no matter how slight, and allow it to vent to the atmosphere, outside the bottle shown. The nipple 5, the threaded collar 6, and the vent insert 7, which are threaded to the upper edge of the container 1, are all manufactured in the manner as previously described in the patent

5,779,071 with the exception that these components are manufactured in a wider dimension, so that they fit over a wide-style flange of the opening of the container 1 shown, thereby providing the type of large volumetric capacity for the bottle, although the standard teat size can be used, to achieve the relationship between its structure, such as the insert and its ventilation port, and the level of any standard amount of formulation applied therein, during use, to achieve the benefits of the present invention. In addition, when the bottle of the present invention is inverted for feeding an infant, the formula may rise to the opposite side of the inverted container 1, but will still have a surface level that will still be below the distal insert. and its ventilation port 4, so that any suction action generated by the infant, during feeding, and the formation of any or part of it, inside the container, during feeding, will be continuously ventilated through its orifice of ventilation 4, through the ventilation tube 3, and the ventilation insert 7, as previously checked. It should be noted that the container 1 of the present invention will obviously include a smaller flattened surface, as in 8, in its lower part, to allow this bottle to stand free, as when not in use, when stored, or when it is warm or heated in preparation for the consumption of its formula content.

Figure 2A shows the container 1 and its bottle when inverted, since during a feeding, it discloses the way in which the liquid level 2 will still be kept below the open vent hole 4, so as not to obstruct the ventilation of any partial ford generated in it, during the feeding process.

Figures 3 and 4 describe a modification of the shape of the container 9 of the bottle shown, with the additional modification that the ventilation tube 10 will be integrally structured with the bottom 11 of the container shown, with its ventilation port generally arranged in the center of the container, as can be seen in 12. Therefore, no matter what position the container 9 of this bottle can take, the level of the surface 13 of the formula will not obstruct the entry of any air flow into the hole of ventilation 12, for ventilation purposes, in this case, outside the lower opening 14 of the container shown. This is so regardless of whether the container 9, as during storage, or feeding, can be placed vertically, as shown in Figure 3, or inverted, as can be understood. In this particular case, the threaded collar 15 and the nipple 16 are conventional, and are threadedly coupled to the wide flange 17 of the container 9, in order to improve the volumetric capacity of the bottle, during use, and to obtain the desired results and required for this particular development. In addition, the structure of the wide flange container 9 is generally spherical, as can be seen in Figure 3, but flattened on its front and rear surfaces, as described in Figure 4, and yet reaches the volumetric capacity of the formula , as desired and required for this development.

Figures 5 and 6 provide both a rear view, and a top view, of the modified bottle as previously described in Figures 3 and 4.

Figures 7 to 9 show an additional modified bottle of the present invention, in which its container 18 has a Mason jar configuration style, thereby providing the wide flange opening style 19, at its upper end, to accommodate the vent tube 20, the receptacle portion 25, the vent insert 21, the teat 22, and the threaded collar 23, which are all threadedly engaged in the threads 24 of the container shown. These components 20 to 23 and 25 are very similar in structure to those previously described in the patent.

5,779,071 with the exception that the components are manufactured to a larger dimension, in order to accommodate the wide flange opening 19 of the container shown 18.

The ventilation tube communicates with its upper inner receptacle portion 25, forming the configuration as a deposit as noted, and positioning it above and locating in the internal ventilation tube 26 of the ventilation insert 21, to function in the manner explained above in patent 5,779,071. But in this particular case, it should be noted that the ventilation hole 27 of the ventilation structure, already all mounted on the wide flange of the volumetric container 18, when inserted, is disposed approximately in the center of the internal space of the container 18 shown , in order to achieve the benefits and results, as explained for the present invention. Therefore, the level of the surface 28 of the formula applied therein will always be below the inlet of the ventilation port 27, in order to avoid its obstruction, regardless of whether the container 18 is kept in its position of resting, as shown in figure 7, or when the container is tilted at any angle, or should be inverted, placed on one side or in any position, such as during the feeding process. This allows the reduced pressure generated inside the container, during feeding with the bottle, to always be vented to the atmosphere. In addition, it is to be noted, in particular after the revision of patent 5,779,071, that wherever these configurations of the ventilation tube and the ventilation insert are inserted into the wide flange and held in position by means of collar 23, that the distal insert and tube ventilation 26 communicate internally with the lateral ventilation passages 29 and open to the atmosphere internally to the collar 23, to provide the ventilation thereof, at all times, to achieve the purposes and advantages of the present invention.

It can also be seen in Figure 8 that the sides of the container 18 can be integrally concave, as in 30, for the grip and holding of the larger size bottle, during use.

Figures 10 to 13 describe a larger volumetric size bottle, which has a container 31 that is generally of a rectangular configuration. It has a wide flange opening, as in 32 to accommodate the neck 33 shown, its supported nipple 34, the vent tube 35 and the vent insert 36 when installed.

The ventilation insert is shown more carefully in Figures 14 and 15, and it can be seen that the lower part of the ventilation port 37 is open, and the ventilation is achieved through the side port 38 which extends to the front and rear of the ventilation tube, to achieve ventilation from inside the container shown. In addition, the side port 38 is disposed approximately at the middle volumetric point of the bottle. In addition, the side ventilation port 38 prevents the entry of any formula 39 therein, such as when the bottle is inverted during feeding. However, as can be seen in Figure 13, the level of the formula will always be in a position separate from the bottom of the vent tube 35, to achieve the purposes of the present invention. In addition, as can be seen in Figure 15, and as noted in patents 5,779,071 and 5,570,796, the vent insert 36 has the side vents 38 that communicate with the opening 35, to allow discharge of any void. , pressure or the like, generated inside the bottle during use, to the atmosphere, outside the bottle, in order to achieve the benefits and results of the present invention.

Figure 16 shows a bottle incorporating a hemispherical container 40, and after having mounted on its integral wide flange 41, the collar 42, the nipple 43, and the vent insert 44 as noted. In addition, the vent tube 45 extends downwardly in the container 40, with the bottom portion 46 of the vent tube being arranged approximately once again at the approximate midpoint of the volumetric capacity of the bottle, to achieve the benefits of The present invention.

Figure 17 discloses a spherical form of a bottle in which the container 61 has been mounted to its wide flange 62 by means of the threaded coupling of the collar 63 and the nipple 64, as noted.

The ventilation tube, in this case, as in 65, extends integrally upwards from the bottom of the container 61, and internally ventilates into the atmosphere, from the bottom of the bottle, and has its side ventilation ports upper end 66 as indicated. Again, these ventilation holes are arranged at the approximate midpoint of the volumetric capacity of the vessel shown, to achieve the benefits of the present invention.

Figures 18 and 19 disclose a modification of the bottle of the present invention, in which the container 51 is generally rectangular of the configuration in one dimension, but has an oval shape 52 along its vertical arrangement. Its neck 53 supports the teat 54, and the vent insert 55 to the wide flange 56 of the integral container 51, for the bottle. The distal insert and its vent tube 57 extend downward, and include an extended vent tube 58, in which its vent hole 59 at its lower end is disposed approximately once again at the volumetric midpoint of the container. shown 51 for the bottle. Therefore, any formula 60 contained therein for feeding will always be below the arrangement of the ventilation port 59, regardless of whether the bottle is supported in a vertical position, as shown in Figure 18, or inverted , as during the feeding.

Figure 20 shows a similar style of bottle, as in Figure 16, but in this case, its container 47 has integrally formed from its flattened lower part 48 an upwardly extending vent tube 49, whose upper end 50, forming the ventilation port, it is arranged once again at the approximate volumetric midpoint of the container shown.

Figures 21 to 25 show variations of the arrangement of the ventilation tube of the present invention. As noted, in Fig. 21 the bottle shown has its container 67 mounted from its wide flange 68, its threaded collar 69, and the nipple shown 70. For ventilation purposes, in this particular embodiment, the tube of ventilation 71 is formed integrally of the container 67, and extends radially inwardly, along an oblique angle, at the approximate midpoint of the container shown, which has its ventilation port 72 disposed approximately in this place, as has been indicated.

Therefore, any formula 73 provided therein, in the amount normally provided to an infant, will always be below the inlet of the ventilation port 72, and does not cause any leakage thereof. This is so regardless of whether the bottle is stored or inverted as during use.

Figure 22 shows the hemispherical style of the container 74 for the bottle shown. The bottle has a wide flange 75, and to which the threaded collar 76 and the nipple 77 are attached.

In this case, similar to that of the bottle as described in Figure 21, the ventilation tube 78 is formed integrally of the container, and is arranged obliquely therein, to arrange its ventilation port, as in 79, and more specifically its side vents 80, internally at the approximate volumetric midpoint of the container shown, to achieve the benefits of the present invention.

Figure 23 is similar to the structured bottle as described in Figure 21, but in this case, as can be seen, the container 81 has its ventilation tube 82 disposed below on the side of the container shown, the opening to the atmosphere as in 83, and having its ventilation port 84 provided at the approximate midpoint of the vessel 81 shown.

Figure 24 shows a bottle structure similar to what was explained previously in Figure 22, but in this particular case, the container 85 has its ventilation tube 86 formed integrally below on the side of the container shown, as can be seen in 87. It may be formed integrally, or structurally applied thereto, as by adhesion of the flanges 88 to the opening 89 provided through the wall of the vessel 85. The inner end of the vent tube 86, has its ventilation port 90, arranged, once again, at the approximate volumetric midpoint of the container shown, in order to achieve the results and benefits of the present invention.

Figures 25 and 26 disclose a further modification to the bottle of the present invention, in which its rectangular configuration container 91 has an oval appearance along the vertical, as can be seen in Figure 26, as in 92.

Sufficient volumetric capacity is provided so that the surface of the formula added thereto, as in 93, will always be below the vent tube 94, and its vent port 95, regardless of the position taken by the bottle, when used. According to the structure of the ventilation features of this development, and as can be seen in Figures 25 and 26, the ventilation tube 94 has lateral vents 96 extending laterally to the sides of the ventilation insert 97, and which allows the ventilation of any pressure or ford developed within the vessel 91 into the atmosphere, passing through the configured threads 101, as can be understood from our previous patents.

As is known from patents 5,779,071 and 5,570,796, the vent insert 97 includes a series of support vanes 98 that provide intermediate spacing, as in 99, and through which the formula can flow, when reversed the bottle, as during a feeding. But, the side vents 96 communicate with the vent tube 94, to allow the passage of any pressure, or lack thereof, through said vent holes, to be discharged into the atmosphere, through the passage through the closure imperfect seal formed by the threaded connection between the collar 100, and the threads 101 of the wide flange structure of the container 91, of the bottle shown. However, the criticality regarding the location of the vent hole 95, at the approximate volumetric midpoint of the container shown 91, is essential in order to avoid any leakage from it, when the formula is applied therein, so that Ventilation can be produced effectively, regardless of whether the bottle is being used, stored, heated, or inverted, such as during feeding.

The bottle components shown in Figure 27 share similarities with those shown previously mounted in Figures 13-15. Figure 27 shows an exploded view of the components minus the liquid tank or bottle. A nipple 115 extends outwardly from a collar 116 that holds the bottle 1. Between the collar and the bottle, a vent insert 117 holds the edge of the bottle 1. The vent insert has a generally hollow cylindrical shape with a low height of the penimeter wall 123. Through the diameter, the vent insert 117 has a side vent 119 with a hole centered toward the direction of the bottle as shown in Figures 27A, 27B. The side vent hole has two opposite openings 118 that generally communicate air between the bottle 1 and the atmosphere. The insert 117 has a main lip 121 and a minor lip 122 concentric and slightly below the main lip 121 as shown below in Figure 27B. Depending on the wall 123, the ventilation insert 117 has the main lip 121 also a contiguous hollow cylindrical shape but slightly smaller in diameter than the ventilation insert. In this way, the ventilation insert can be applied in a tight seal within the edge of the bottle, during its installation, and thus avoid any leakage from the ventilation insert other than the desired air ventilation from the structure. of the insert and its applicability and use in a bottle. This opening is provided at 114, by the contoured ventilation tube 113, which is shown in the preferred embodiment as conical, although other shapes are possible. In addition, the lower part of the vent tube normally ends, in this case, in the vicinity of the inner bottom of any bottle on which the ventilation structure of the present invention is applied, regardless of whether it is the standard bottle , of a wide flanged bottle, or the like. The main lip has a circumferential protuberance 124 of slightly larger diameter than the main lip. The protrusion of the main lip seals the insert with the inside diameter of the bottle. The main lip has an outer diameter than the inner diameter of the bottle. Depending on the lateral ventilation 119, the ventilation insert 117 has the smaller lip 122 as a hollow cylindrical shape of smaller diameter than the main lip. The minor lip 122 has a circumferential protuberance 125 of slightly larger diameter than the minor lip. The lower lip has an outside diameter of the inside diameter of the tank. The labia minora seal the reservoir 126 of the vent tube of the present invention to the vent insert 117.

The ventilation tube 113 has a reservoir 126 which has a generally hollow cylindrical shape with an open upper part 127 and a partially closed lower part 128. The lower part is smoothed and rounded as it descends distally from the upper part. In the center of the lower part 128, an opening 129 provides the passage for the ventilation tube 113 attached to the lower part. The ventilation tube below,

it reaches a hollow truncated conical shape with the larger diameter 130 located towards the reservoir 126 and the narrow diameter 131 located distally.

Coaxial with the vent tube 113, the vent insert 117 has the distal insert or inner vent tube 120 centered in the hole in the vent side 119 and perpendicular to the side vent 119 opposite the insert wall 123. The tube of internal ventilation 120 is a hollow cylinder of a length greater than its diameter. The internal ventilation tube 120 communicates air, but not supply liquid in the present invention, from the lateral ventilation 119 in the reservoir 126 of the ventilation tube 113.

Figure 28 shows the ventilation tube 113 alone and having a large diameter 130 in the vicinity of and similar in diameter to the bottom 128 of the reservoir 126. The ventilation tube 113 then narrows distally next, towards the narrow diameter 131. In the preferred embodiment, the larger diameter 130 is approximately twice that of the narrow diameter 131, a ratio of approximately 2: 1.

Figure 29 shows again the vent tube 113 alone, but with the larger diameter 130 substantially smaller than previous embodiments. In this embodiment, the larger diameter 130 reaches at least one octave more than the diameter of the narrow diameter 131. Towards the narrow diameter 131, the ventilation tube 113 narrows distally as before. In this embodiment, the largest diameter 130 is slightly larger than the narrow diameter 131, a ratio of approximately 1.1: 1.0.

Figure 30 shows a prior art bottle in use by a chewing infant with the bottle lowered below a horizontal orientation ready to be picked up by the infant. This bottle 1 has a constant diameter cylindrical tube. With a bottle tilted down, the tube contacts the feed liquid. When the nipple is compressed quickly, as during chewing, compressed air above the liquid pressurizes the liquid briefly into the container. Compressed air advances from the nipple through the vanes of the insert and into the container, pressurizing it. Pressurized air forces the liquid through the prior art ventilation tube that has straight walls and a constant diameter. The liquid in the ventilation tube suddenly and abruptly enters the insert where it exits the bottle through the side ports of the inserts. The liquid that has come out is then filtered to an infant or a caregiver.

The conical vent tube of the present invention, shown in Figure 31, dissipates the induced feed liquid in the vent tube. A contoured tube, particularly conically, dissipates the pressure on the liquid inside the tube when the diameter of the tube expands and the feed liquid flows smoothly into the reservoir instead of abruptly escaping through the ventilation holes as in the technique previous. When a bottle 1 in Figure 31 has a vent tube of a conical shape and an increasing diameter from the narrow distal end 131 to the widest proximal end 130, a baby chewing on the teat 5 pressurizes liquid 2, but the increase in diameter of the ventilation tube reduces the incremental volume inside the tube and discourages the supply liquid 2 from leaving the bottle 1 in the insert 119 and filtering from the collar 6. The diameter of the increasing ventilation tube limits any increase in pressure inside the bottle 1 and therefore the leaks of the bottle are avoided by the present invention.

From the above description, a fully ventilated wide flange bottle, or other diameter, has been described. This bottle is only capable of reducing pressure increases inside a ventilation tube and prevents leakage of the bottle. This bottle and its various components can be manufactured from many different materials, including but not limited to, low density polyethylene polymers, high density polyethylene, polypropylene, glass, nylon, ferrous and non-ferrous metals, their alloys and compounds .

Variations or modifications to the subject matter of the present invention may occur to those skilled in the art when reviewing the development as described herein. Such variations, if within the scope of this development, are intended to be encompassed within the principles of the present invention, as explained herein. The description of the preferred embodiment, in addition to the representation within the drawings, is set forth for illustrative purposes only.
