Description

FIELD OF THE INVENTION

The fully ventilated feeding bottle with a wide rim and a profiled ventilation pipe generally refers to infant care products. More specifically, the present invention relates to feeding bottles having an inner pipe that prevents the formation of a vacuum inside the bottle and helps the infant suck out the liquid from the bottle.

BACKGROUND OF THE INVENTION

A unique feature of the present invention is a ventilation pipe with an increasing diameter, due to which it is fully ventilated both during use and storage.

In children, there is an instinct to suck milk from the mother's breast. However, for various reasons, children are often given other liquids to drink. Children are not able to drink from ordinary glasses and cups without spilling liquid. Therefore, children are fed from feeding bottles. The feeding bottle has a nipple made of silicone, latex, rubber or other material with an opening at the end, attached to the neck of the feeding bottle. Existing feeding bottles are filled with liquid, a ventilation pipe is inserted, the nipple is fixed, the bottle is turned over, the nipple is placed in the child’s mouth and the child drinks from it.

The feeding bottles ventilated through the rim of the nipple are tightly closed, with the exception of the opening in the nipple. As the child drinks, the volume of liquid in the bottle decreases and the vacuum increases proportionally, due to which the liquid becomes contaminated. However, the ventilation pipes allow atmospheric air to enter the bottle usually behind the liquid while the child is drinking. Ventilation pipes reduce the vacuum generated in the bottle during use. Ventilation pipes increase fluid flow from the nipple and make it easier for the baby to suck it out. A child is less likely to absorb air and cause colic (abdominal pain).

The infant feeding containers initially had a narrow opening at the top to which the nipple was attached. According to the observations of infant care specialists, the narrow opening prevented easy access to the inside of the bottle, and also prevented easy cleaning of the bottle from the inside. Then the manufacturers eliminated this shortcoming by starting the production of bottles with a larger diameter hole. These bottles have been successfully marketed.

Wider openings required the release and use of nipples and horns for feeding with larger flanges corresponding to the diameter of the opening in the bottle. Larger flanges prevented leakage at the junction with the bottle. However, larger diameter nipples with the same distance from the upper end to the lower end of the nipple had greater volumetric capacity.

In addition, infants often chew nipples, although the nipples are designed to suck out fluid from the bottle. In this regard, the nipples and other devices for feeding have a hardened structure that can withstand chewing. Nipples most often chew babies that are problematic in terms of feeding, such as babies with neurological disorders or disorders. Neurological disorders or disorders in infants cause rapid chewing of objects that enter the mouth, usually the nipples.

During rapid chewing of a nipple for feeding, especially having a larger diameter and internal volume, the baby pushes the air deeper into the bottle itself. Air entering the bottle can increase pressure inside the bottle. Due to the increased pressure, the liquid often forcibly enters the distal end of the vent pipe located inside the bottle. Liquid under pressure passes through the ventilation insert and the ventilation pipe, leaves the bottle and spills.

Chewing leakage also occurs when entrained air stops midway inside the cylindrical ventilation pipe. Due to the pressure inside the cylindrical ventilation pipe, part of the liquid may be trapped in the pipe by an air bubble resulting from the baby's chewing nipple. Ideally, the air bubble that usually enters the nozzle when the bottle is turned over to feed the baby should be forced out.

However, an air bubble trapped in the ventilation nozzle does not allow fluid in the far part of the nozzle to pass through the nozzle and enter the far part of the bottle. The liquid cannot enter the enlarged part of the supply pipe for its corresponding discharge by the ventilation pipe. Consequently, the supply fluid may then impair the ventilation function of the nozzle.

Many attempts have been made to create a feeding bottle with a vent to reduce the formation of vacuum during use. Still in US patent US 598231, issued in the name of Roderick, a feeding bottle with a C-shaped pipe is proposed. However, when an ordinary child lifted the bottle, a portion of the liquid remained in the C-way nozzle. The remaining liquid blocked the nozzle and prevented atmospheric air from releasing the vacuum inside the bottle. Other patents have proposed similar methods and means for discharging air from within a container, as described in US Pat. No. 927,013. In addition, other means for discharging air from within a feeding bottle are described in US Pat. No. 1,441,623 and US Pat. No. 2,061,477.

In previous US patents US 5779071 and US 5570796, issued in the name of the applicants of this application, describes the ventilation and internal nozzles that prevent the formation of partial vacuum during use and prevent spillage. US Pat. No. 5779071 proposes a vent pipe extending inside a bottle. The ventilation pipe has the shape of a hollow cylinder that protrudes sufficiently downward into the bottle. US Pat. No. 5,570,796 teaches a reservoir located above a label on a bottle. The reservoir communicates with a system of tubes for replacing the suction fluid with air from the reservoir, thereby preventing the formation of a partial vacuum in the bottle. Bottles for feeding multiple designs are known in the art. In many cases, inside the bottle while consuming its contents, for example when feeding a baby, a vacuum often forms. It is believed that the vacuum is the cause of various physiological disorders in the infant, which is exposed to it. The vacuum created inside the bottle when the baby sucks the liquid out of the bottle can cause an imbalance in pressure at the location of various organs of the body, such as the ear canal, and cause ear infections, speech delay, delayed motor activity, developmental delay, illness, or other difficulties. Thus, one of the tasks in the production of products for the care of infants is to create a bottle for feeding with a ventilation tool to prevent the formation of vacuum inside the bottle. In previous patents US 57790071 and US 557079696, issued in the name of the applicants of this application, such a bottle is proposed having a vent pipe located outside the cap at the upper end of the bottle, extending into the bottom of the bottle and acting as a ventilation pipe during use of the contents of the bottle when it is partially or completely inverted.

At the same time, the present invention provides a means of relieving air pressure inside the bottle and preventing the formation of vacuum or pressure therein, regardless of whether the bottle is used, whether it is stored in an upright position, or partially or completely turned upside down, as is the case when the contents are used.

Other US patents related to the subject of the present invention include US 189691, US 345518, US 679144, US 834014, US 1600804, US 2156313, US 2239275, US 2610755, US 2742168, US2744696, US 3059707, US 5570796 and others. In addition, the relevant UK patents GB 273185 and GB 454053 are known.

The present invention overcomes the disadvantages of the prior art ventilated nipple feeding bottles, in which it is necessary to reduce the vacuum inside the bottle using ventilation tubes. Thus, the present invention proposes a tapering ventilation pipe, allowing quickly and at a distance from the pipe to release air and return fluid in a timely manner to the container, thereby limiting the formation of vacuum inside the feeding bottle. The enlarged proximal vent portion minimizes the possibility of leakage from the bottle. The bottle of the present invention is easy to clean, withstands arbitrary chewing of the nipple and relieves the pressure generated by chewing. In the present invention, leakage is prevented and the bottle is continuously ventilated, whereby air bubbles are dispersed in the vent pipe.

Summary of the invention

Accordingly, the present invention provides a vent pipe for a feeding bottle, which is improved by changing its shape. The ventilation pipe has a profiled, generally and preferably conical shape, with a diameter greater in the upper part and less in the lower part. Due to the conical shape, it is possible to let air into the bottle at a distance and immediately release the liquid into the capacity of the ventilation pipe. The conical shape prevents liquid from entering the liner, due to which the bottle is directly ventilated and leakage of liquid from it is prevented.

In addition, the present invention provides an improved ventilation duct for reducing the internal pressure of a liquid and air. At the expanded proximal end of the ventilation pipe, pressure transmission due to compression of the nipple is reduced. When the milk bottle is squeezed and the milk rises, falling into the ventilation pipe, the compression force is lost due to the ventilation pipe expanding upward. Due to the expanding conical shape, the ejection of liquid from the bottle directly into the ventilation insert and the occurrence of leaks are prevented. This is due to the fact that the pipe has a conical shape with an expanding distal end, which allows you to dissipate the pressure of the compressed air and gradually enter the fluid into the container. By preventing the ejection of fluid into the liner, the conical shape prevents leakage from the bottle.

Moreover, due to the expanding conical part, the capacity of the container increases. As the baby empties the bottle and the liquid level drops below the maximum, the liquid in the container quickly and efficiently leaves the container. When the person caring for the baby or the baby holds the bottle upright, the liquid immediately leaves the container in the expanded part of the conical pipe, and the rest of the liquid returns to the bottle.

The present invention provides for the instantaneous and complete movement of any air bubble resulting from a baby chewing a nipple into the distal end of the vent pipe. The present invention also provides for the movement of the liquid in front of the air bubble into the capacity of the ventilation pipe. Due to this, the ventilation pipe operates in a given automatic and continuous mode.

The present invention establishes a constructive relationship between the container or vessel and the mixture inside the bottle for feeding. The feeding bottle is large enough so that as the mixture is prepared and placed in the container, the surface of the mixture remains below the ventilation opening or the opening leading out of the container to provide ventilation. In addition, even when the container is turned upside down by the infant or the caretaker during feeding, the liquid mixture in any position does not approach the far opening of the liner. Thus, it is an object of the present invention to provide a container with sufficient capacity and volume so that, regardless of the dose (113 g, 170 g, 227 g or any other quantity) entering the container of the mixture or milk, the aforementioned ventilation opening always remains open and retains the ability to Ventilate the feeding bottle under any conditions.

Thus, a significant positive or negative pressure cannot be created in the container, since the ventilation hole is open to provide an exhaust when the bottle is in an upright position, for example, when it is heated or heated, it is prepared for feeding, and even when the bottle is turned upside down, for example, feeding time, as a result of which any negative pressure created inside the container is released when the baby sucks the contents of the bottle.

This feature of a container with sufficient internal volume is ensured by the use of containers with excess dimensions, for example, wide spherical containers or cylindrical containers with flattening of each surface, or containers whose size corresponds to the size of a jar with a screw cap. In one case, the container may have a spherical shape. In another embodiment, the container has a cylindrical shape, but with flattening on the sides. In an additional embodiment, the container may be in the form of a jar or even be slightly concave on the sides to facilitate grip. In addition, when using containers of a spherical or cylindrical shape, they can have a flattened bottom to stabilize the feeding bottle when it rests on any surface.

In a preferred embodiment, the ventilation hole inside the insert communicates with the ventilation pipe and side ventilation slots in the insert, which is attached to the top of the container with a corresponding ring with an internal thread holding the insert, the ventilation pipe in the container, and a conventional nipple in place. The ventilation hole in the liner associated with the ventilation pipe may lead directly down to the vessel, which may have side holes on each side to prevent the mixture from entering the ventilation pipe and to allow ventilation when the container is turned over during use.

In an additional embodiment, the container, ring and nipple can be made as standard, but have a volume like that of the figured containers described above, and the ventilation pipe and the hole in the liner can pass through the surface of the container rather than communicating with the ring, as described in US Pat. No. 5779071 .

At the same time, the ventilation opening leading to the ventilation pipe can be located approximately in the center of the container, regardless of the shape or design of the container, due to which the mixture is lower or higher than the ventilation hole when the feeding bottle is in its original position or turned upside down during use, as This is described earlier.

Thus, the object of the invention is the creation of a new and improved ventilation nozzle of bottles for feeding infants.

An additional objective of the present invention is the dispersion of pressure on the liquid in the bottle in order to prevent liquid from entering the liner and thereby eliminate leaks.

Another additional objective of the present invention is to provide a direct exit of air bubbles when the bottle is turned over.

Another additional objective of the present invention is to provide a noticeable increase in the volume of the tank by increasing the diameter of the conical shape, whereby the liquid immediately spills out of the tank.

Another additional objective of the present invention is to provide a volumetric container for use as a feeding bottle, including a ventilation pipe with a liner, which is located approximately in its center, due to which the mixture or milk inside does not cover the ventilation hole inside the liner, when the bottle is used for feeding the baby or when it rests on the base, for example, during storage, when heated or in its original position.

Another additional objective of the present invention is the creation of a structured means inside the bottle for feeding, providing a continuous release of pressure or vacuum created inside its container, regardless of whether the appropriate bottle is used.

Finally, another objective of the present invention is the creation of a ring with a wide rim or other design for use with a standard wide-necked capacity in the form of a bottle for feeding and applicable for feeding a baby formula.

Data and other tasks will become clearer for specialists in this field of technology after reading the description of the invention and the preferred option in combination with the attached drawings.

Preferred Embodiment

The present invention overcomes the disadvantages of the prior art and proposes a fully ventilated feeding bottle with a wide rim or other size, having a tapering ventilation pipe to eliminate the vacuum inside the tank and prevent leakage from the tank. In the drawings, in particular, FIGS. 1 and 2, a fully ventilated feeding bottle with a wide rim or a different size is proposed in the present invention. It includes a spherical container 1 of large capacity, due to which a solution to the claimed problems of the invention is provided. In other words, when the container is filled with a mixture, for example, indicated by position 2, in an amount usually sufficient to feed the infant, it will fill the container only to a level located significantly below the lower end of the ventilation pipe 3, and, more accurately, as can be seen, away from the insert and its ventilation hole 4.

Thus, if the pressure inside the container rises when the feeding bottle is heated, it will immediately be released to atmospheric pressure, since the ventilation hole 4 of the distal liner is open and absorbs any generated pressure, regardless of how small it is, leading it to the outside atmosphere specified bottle for feeding. Nipple 5, a ring with an internal thread 6 and a ventilation insert 7, which are screwed onto the upper end of the container 1, can be manufactured by the method described in US Pat. No. 5779071, except that these elements are expanded in accordance with the design of the wide rim of the hole the specified capacity 1, due to which the feeding bottle has a large capacity even when using a standard size nipple, and provides a relationship between the elements of its design, such as the liner and its ventilation hole the level of any standard amount of the mixture, wherein it is filled during use, providing the advantages of the present invention. In addition, when the feeding bottle of the present invention is turned over to feed the infant, the level of the mixture on the opposite side of the inverted container may increase, but still remain below the distal insert and its ventilation opening 4, so any suction action that the baby creates during feeding time, and the vacuum or partial vacuum generated inside the container during feeding is continuously withdrawn using the ventilation hole 4 through the ventilation pipe to 3 and from the vent insert as described previously. It should be noted that the container 1 proposed in the present invention, of course, has a small flattened surface at the bottom, for example, indicated by 8, which allows the bottle to stand freely when not in use during storage or when heating or heating to prepare for use in it mixtures.

Fig. 2A shows a container and bottle for feeding in an inverted position, as during feeding, to illustrate how liquid level 2 still remains below the level of the open air vent 4 and does not prevent the removal of any partial vacuum created internally during feeding.

Figures 3 and 4 show a container 9 of a feeding bottle, in which the shape has been improved and the ventilation pipe 10 has been improved, which is made as a whole with the bottom 11 of the container, while its ventilation hole, indicated by 12, is located in the whole center capacities. Thus, regardless of the position of the container 9 of this bottle for feeding, the level 13 of the mixture does not block the flow of air into the ventilation hole 12 for ventilation in this case from the lower opening 14 of the shown container. It does not matter if the container 9 is in a vertical position, as during storage or feeding, as shown in figure 3, or upside down. In this particular case, in order to increase the capacity of the feeding bottle during use and to achieve the results desired and necessary in this particular embodiment, the ring 15 with internal thread and the nipple 16 are connected to the wide rim 17 of the container 9 by means of a common thread. In addition, the wide rim of the container 9 has a generally spherical shape, as shown in figure 3, and flattened front and rear surfaces, as shown in figure 4, but provides the desired and necessary in this embodiment property of the mixture.

In FIG. 5 and 6 show a rear view and a front view of the improved feeding bottle described previously with reference to FIG. 3 and 4.

7-9 show an additionally improved feeding bottle according to the present invention, in which the container 18 is made like a jar with a screw cap and has a neck with a wide rim 19 located on the upper end for installing the ventilation pipe 20, the receiving part 25, the ventilation insert 21, the nipple 22 and the ring 23 with an internal thread, wherein all of the listed elements are fixed to the tank shown by the thread 24. The design of the said elements 20-23 and 25 is close to the design of the elements OF DATA in US Patent 5779071, except that the data elements extended in accordance with the design of the neck with a wide rim 19 of said container 18.

The ventilation pipe is in communication with the upper inner receiving part 25 in the form of a tank, as noted above, on which the ventilation pipe 26, whose function is previously described in US Pat. No. 5,777,071, is installed and placed in it. However, in this particular case, it should be noted that in order to provide the advantages and results claimed in the present invention, the ventilation hole 27 of the ventilation structure, which is entirely attached to the wide rim of the tank 18, after installation and located approximately in the center of internal space shown container 18. Therefore, the level of the mixture 28 in tank 18 will always be below the entrance to the vent hole 27 to prevent it from blocking, regardless of whether vessel 18 is in the rest position, as shown in FIG. 7, or tilted at any angle, or upside down, is on its side or in any position, as during feeding. This allows you to always release into the atmosphere the reduced pressure generated inside the container during feeding from the bottle. In addition, it should be noted, especially taking into account the patent US 5779071, that after installing the ventilation pipe and the liner of this design on the wide rim and fastening them using the ring 23, the distal liner and the ventilation pipe 26 communicate from the inside with the side ventilation ducts 29 and communicate with the atmosphere from the inside of the ring 23, ensuring its constant ventilation in accordance with the stated objectives and advantages of the present invention.

FIG. 8 also shows that the container 18 may have concave side surfaces indicated at 30 to facilitate gripping and holding the large bottle during use.

10-13, a larger capacity feeding bottle is shown having a container 31 of a generally rectangular shape. It has a neck with a wide rim, indicated by 32, for mounting the shown ring 33, the teat resting on it, the ventilation pipe 35 and the ventilation insert 36.

On Fig and 15 shows in more detail the ventilation insert and it is seen that the ventilation hole 37 is open from the bottom, and ventilation is provided through the side hole 38, which reaches the front and rear sides of the ventilation pipe, whereby the shown capacity is ventilated from the inside. In addition, the side opening 38 is located approximately at the midpoint of the volume of the bottle. In addition, the side opening 38 prevents the mixture 39 from getting into it when the bottle is turned over during feeding. However, as shown in FIG. 13, the level of the mixture is always at a certain distance from the lower end of the ventilation pipe 35 in accordance with the objectives of the present invention. In addition, as shown in FIG. 15 and indicated in US Pat. Nos. 5,777,071 and 5,570,796, the ventilation insert 36 has side openings 38 that communicate with the nozzle 35, thereby releasing vacuum, pressure, and the like created inside the bottle for feeding during use, to the atmosphere outside the bottle in accordance with the stated objectives and advantages of the present invention.

On Fig shows a feeding bottle with a hemispherical capacity 40 and made as a whole wide rim 41, on which the ring 42, the nipple 43 and the ventilation insert 44 are mounted. In addition, it is shown that the ventilation pipe 45 passes downward into the container 40, with this lower end is also located approximately at the midpoint of the volume of the bottle for feeding in accordance with the claimed advantages of the invention.

On Fig shows a bottle for feeding a spherical shape with a capacity of 61 and a wide rim 62, on which a ring 63 and a nipple 64 are fixed using thread.

In this case, the ventilation pipe 65 is made integrally with a capacity of 61, extends upward from its bottom and exits from the inside from the bottom of the bottle to the outside, and side vents 66 are located at its upper end. These vents are also located approximately at the midpoint of the volume shown containers in accordance with the claimed advantages of the invention.

FIGS. 18 and 19 show an improved feeding bottle according to the present invention, in which the container 51 has a generally rectangular shape in one dimension and an oval sectional shape 52. On the wide rim 56, made as a unit with the capacity 51 of the bottle for feeding, with the help of the ring 53 the nipple 54 and the ventilation pipe 55 are fixed. The distal insert with the ventilation pipe 57 extends downward and is extended by the ventilation pipe 58, located at its lower end the ventilation hole 59 is also located at approximately the midpoint of the volume of the shown capacity of the bottle 51 for feeding. Thus, any inside of the feeding mixture 60 will always be below the ventilation hole 59, regardless of whether the feeding bottle is upright, as shown in FIG. 18, or is turned upside down during feeding.

In Fig.20 shows a feeding bottle, similar to the bottle shown in Fig.16, but with the difference that its capacity 47 has an upwardly extending ventilation pipe 49, which is made integrally with its flattened bottom 48 and has an upper end 50 forming a ventilation hole and also located approximately at the midpoint of the volume of the shown capacity.

On Fig-25 shows the design options proposed in the present invention, the ventilation pipe. On Fig shows a feeding bottle with a capacity of 67, on which is mounted a wide rim 68, a ring 69 with an internal thread and a nipple 70. In this particular embodiment, the ventilation pipe 71 for ventilation is made in one piece with a capacity of 67 and passes inside in the radial direction at an oblique angle approximately to the center of the shown tank, where its ventilation hole 72 is located.

Thus, the mixture inside 73 in the amount normally fed to the infant will always be below the entrance to the ventilation hole 72 and will not spill. It does not matter if the bottle for feeding is in an upright position, as during storage, or upside down, as during feeding.

On Fig shows a feeding bottle with a hemispherical capacity 74. The bottle has a wide rim 75, to which is attached a ring 76 with an internal thread and a nipple 77.

In this case, as in the case of the bottle shown in Fig. 21, the ventilation pipe 78 is made integrally with the container, passes obliquely inside it and has a ventilation hole 79 and, more precisely, internal side ventilation holes 80 located approximately in the midpoint of the volume of the shown capacity in accordance with the claimed advantages of the invention.

On Fig shows a feeding bottle, similar to the bottle shown in Fig.21, but with the difference that the ventilation pipe 82 is offset lower along the tank 81 and communicates with the atmosphere in the position indicated by the position 85, and its ventilation hole is located approximately in the midpoint of the volume of the displayed capacity 81.

On Fig shows a feeding bottle, the design of which is similar to the design of the bottle shown in Fig.22, but in this particular case, the ventilation pipe 86, made in the form of a single unit with a capacity of 85, is shifted lower along the tank to the position indicated by 87. It can be integral and structurally combined, for example, by means of flanges with an opening 89 in the wall of the container 85. At the inner end of the ventilation pipe 86, a ventilation hole 90 is provided, which is also located approximately in the middle It point volume container shown in accordance with the stated objects and advantages of the present invention.

Figures 25 and 26 show an additionally improved feeding bottle according to the present invention, which has a rectangular oval-shaped container 91 in cross section, as indicated by 92 in Fig. 26.

Since it has sufficient capacity, the level of the mixture in it, indicated by 93, will always be below the ventilation pipe 94 and its ventilation hole 95, regardless of the position of the feeding bottle during use. As shown in FIGS. 25 and 26, in this embodiment, the ventilation pipe 94 has lateral openings 96 extending laterally to the ventilation insert 97 and allowing the pressure or vacuum generated in the container 91 to be released into the atmosphere through a thread 101, as described in our previous patents.

As is known from the patents '071 and 796', the ventilation insert has several support blades 98 with an intermediate space 99 for the receipt of the mixture when the bottle for feeding is turned over, as during feeding. The side openings 96 are in communication with the ventilation pipe 94, allowing pressure or lack thereof to be released to the atmosphere through a partial seal formed by a threaded connection between the ring 100 and the thread 101 of the container 91 with a wide rim of the feeding bottle shown. However, the position of the ventilation hole 95 at approximately the midpoint of the volume of the container 91 shown is essential to prevent leakage from the container regardless of whether the bottle is used, stored, heated or turned upside down, as during feeding.

The bottle components shown in FIG. 27 are similar to the components illustrated in FIGS. 13-15. On Fig shows the image of the components in disassembled form with the exception of containers or bottles for liquids. A nipple 115 extends from the ring 116 attached to the bottle 1. A ventilation insert 117 is located between the ring and the bottle and grabs the rim of the bottle 1. The ventilation insert is in the form of a hollow cylinder with a low outer wall 123. The ventilation insert 117 has a lateral nozzle 119 transversely arranged across the diameter with a centered hole facing in the direction of the bottle, as shown in figa, 27B. The side pipe has two opposing openings 118 for exchanging air between the bottle 1 and the atmosphere. The insert 117 has a large protrusion 121 and a small protrusion 122 located concentrically and slightly below the large protrusion 121, as shown in figv. Below the wall of the ventilation insert 117, 123 is located a large protrusion 121, also in the form of a hollow cylinder adjacent to the ventilation insert, but having a slightly smaller size. Due to this, the ventilation insert can be sealed inside the rim of the bottle to prevent leakage in addition to air release according to the requirements for the design of the insert and its applicability in the feeding bottle. Reference numeral 114 denotes an opening in a shaped ventilation pipe 113, which in a preferred embodiment has a conical shape, although other shapes are possible. In addition, in this case, the ventilation pipe usually ends near the bottom of any feeding bottle on which the ventilation structure of the present invention is mounted, whether the bottle is standard, has a wide rim and the like. The large protrusion has an annular thickening 124, the diameter of which slightly exceeds the diameter of the large protrusion. The thickening of the large protrusion serves as a seal between the liner and the inner diameter of the bottle. The outer diameter of the large protrusion corresponds to the inner diameter of the bottle. Below the side pipe 119 of the ventilation insert 117 is a small protrusion 122 in the form of a hollow cylinder of a smaller diameter than the diameter of the large protrusion. Small protrusion 122 has an annular thickening 125, the diameter of which slightly exceeds the diameter of the small protrusion. The outer diameter of the small protrusion corresponds to the inner diameter of the tank. A small protrusion serves as a seal between the reservoir 126 of the ventilation pipe and the ventilation insert 117.

The ventilation pipe 113 has a reservoir 126 in the form of a hollow cylinder with an open top 127 and a partially closed bottom 128. The bottom is smoothed and rounded as it moves away from the top. A hole 129 is located in the center of the bottom 128 for the ventilation pipe 113 connected to the bottom. The ventilation pipe has the shape of a hollow truncated cone, facing with its large diameter 130 to the reservoir 126 and the smaller diameter 131 down.

Located on the same axis as the ventilation pipe 113, the ventilation insert 117 has a distal insert or an internal ventilation pipe 120 in the center of the hole in the side pipe 119 and perpendicular to the side pipe opposite the wall 123 of the insert. The internal ventilation pipe 120 is in the form of a hollow cylinder whose length exceeds its diameter. According to the present invention, the internal ventilation pipe 120 passes air, but not the nutrient mixture, from the side pipe 19 into the tank 126 of the ventilation pipe 113.

On Fig separately shows the ventilation pipe 113, while its large diameter 130, which corresponds to the diameter of the bottom 128 of the tank 126, it is adjacent to the bottom 128. Further, the ventilation pipe 113 comes on a cone, at the end of which has a smaller diameter 131. In a preferred embodiment the implementation ratio of a larger diameter 130 and a smaller diameter 131 is approximately 2: 1.

FIG. 28 also shows separately the vent pipe 113, but its larger diameter 130 is substantially smaller than in previous embodiments. In this embodiment, the larger diameter 130 is at least one-eighth larger than the smaller diameter 131. Ventilation pipe 113 also converges to a cone at the end of which has a smaller diameter 131. In this embodiment, the larger diameter 130 is slightly larger than the smaller diameter 131, and their ratio is approximately 1.1: 1.0.

On Fig shows a well-known from the prior art bottle, lowered below the horizontal level to facilitate its capture by the infant during feeding. Bottle 1 has a cylindrical pipe with a constant diameter. When the bottle is tilted down, the tube contacts the nutrient mixture. When the nipple is quickly squeezed, as when chewing, compressed air above the liquid for a short time creates excessive pressure of the liquid inside the container. Compressed air passes from the nipple through the blades of the liner and enters the tank, creating excessive pressure in it. The injected air pushes the liquid up into the prior art ventilation pipe, which has straight walls and a constant diameter. The fluid in the vent pipe suddenly and abruptly enters the liner and exits the bottle through the side openings of the liner. The escaping fluid is then spilled onto the child or the carer.

Proposed in the present invention, the conical ventilation pipe, which is shown in Fig. 31, disperses the liquid nutrient mixture that is sucked into it. A profiled pipe, in particular a conical shape, disperses the pressure on the liquid inside the pipe as it expands, and the liquid feed mixture smoothly enters the tank instead of a sharp leak from the ventilation holes, as is known from the prior art. If the bottle 1 shown in FIG. 31 has a cone-shaped ventilation pipe, the diameter of which increases from the narrow distal end 131 to the wide proximal end 130, the baby, compressing the nipple 5, creates excessive pressure of the liquid 2, but due to the increasing diameter of the ventilation pipe the increase in volume inside the tube is reduced and the nutrient mixture 2 is prevented from leaving bottle 1 through liner 119 and leaking from ring 6. Due to the increasing diameter of the ventilation pipe, the increase is limited the pressure inside the bottle and, thus, is prevented from leaking from the bottle according to the present invention.

Above is a fully ventilated feeding bottle with a wide rim or other diameter. This feeding bottle has the unique ability to reduce the increasing pressure inside the ventilation pipe and prevent leakage from the bottle. A feeding bottle and its various components can be made of a variety of materials, including without limitation polymers, low density polyethylene, high density polyethylene, polypropylene, glass, nylon, ferrous and non-ferrous metals, their alloys and composites.

Specialists in the art who are familiar with the described invention can make various changes and improvements to it. Such changes, if they are not outside the scope of the invention, are considered to be within the scope of the present invention. The description of the preferred embodiment, as well as the images in the drawings, are for illustrative purposes only.
