Abstract

Bottles made up of large volumes of containers always have vent tubes extending to vent pressure. The bottle may have a cylindrical shape or other shape that prevents the flow located within the container from blocking the vent tube regardless of each arrangement of the container. The vent tube extends distal from the vent insert and is operatively associated with a collar that holds the nipple in the vent structure and the wide rim opening. In addition, the vent tube has a conical shape that decreases in diameter as it moves toward the center of the bottom to disperse the pressure that may cause leakage from the bottle. The vent insert also has a large seal and a small seal that prevent leakage to the outside of the collar and to the infant.

Fully ventilated wide rim bottles with contour vent tubes generally relate to infant care products. More specifically, the present invention relates to a baby bottle having an inner tube that prevents vacuum in the baby bottle and helps the infant to suck up liquid from the baby bottle.

A particular embodiment of the present invention is an enlarged diameter of the vent tube that provides complete aeration during use and storage.

Babies have an instinct to suck milk from their mother. For various reasons, babies often drink liquids from other sources. Babies lack the ability to drink with regular glasses and cups without spilling. Thus, the liquid is fed to the baby using a baby bottle or baby bottle. The bottle is a nipple with a hole in the end of the bottle fixed in the opening of the top of the bottle and is made of silicone, latex, rubber or other material. Current bottles are used by filling the bottle with liquid, inserting vents, fixing the nipple, flipping the bottle, placing the nipple in the baby's mouth, and the baby drinking liquid from the nipple.

The bottle, vented from the rim of the nipple, is tightly sealed except for the nipple opening. When caring for a baby, the volume of the liquid in the bottle is reduced and the bottle's vacuum increases proportionately to contaminate the liquid. However, the vent tube allows ambient air to generally enter the bottle from behind the liquid while the baby sucks the bottle. The vent holes reduce the vacuum created by the baby sucking the bottle inside the bottle. The vent holes improve the flow of liquid out of the nipple and make it easier for the baby to suck the bottle. The risk of babies sucking in the air is reduced, which in turn reduces the babies crying.

Infants and hydraulic feeding vessels originally had narrow, superior orifices with nipples attached. Caregivers pointed out that narrow openings prevented rapid access to the inside of the bottle and prevented easy cleaning of the inside of the bottle. Producers have argued that bottles with large diameter openings have disadvantages. These bottles have been successful in the market.

Larger openings required the production and use of nipples and feeding tubes with flanges of larger diameter that matched the openings of the bottle. However, larger diameter nipples having the same distance from the top to the lower end of the nipple had a larger volume contained by the nipple.

In addition, babies often chew nipples, even if the nipples are designed to be sucked to remove fluid from the bottle. Therefore, nipples and other feeding accessories must be rigid in design to withstand chewing. By chewing nipples, feeding problems such as neurological delays or deficiencies occur more frequently in infants. Neurological delays lead to the movement of an object placed in the mouth, such as a nipple, frequently chewed by an infant.

While frequently chewing feed nipples, especially those with larger diameters and internal volumes, the infant promotes air spread within the bottle itself. Air introduced into the bottle can increase the pressure inside the bottle. The increased pressure forces liquid spreading in the vent tube located in the bottle. Under pressure, the liquid exits the bottle across the vent insert and the vent tube, causing the liquid to exit the bottle.

Also, when the introduced air stops in the middle of the cylindrical vent tube, a leak occurs by chewing action. Due to the pressure in the cylindrical vent tube, some liquid may be trapped in the vent tube by air bubbles caused by the chewing behavior of the infant. As the bottle turns over and enters the tube when it is in the feeding position for the infant, air bubbles must be released.

However, air bubbles trapped in the vent tube prevent the liquid at the distal end of the vent tube from crossing the vent tube to the end of the bottle. Prevents liquid from entering the enlarged reservoir of the transfer tube for proper aeration by the vent tube. The conveying liquid then interferes with the aeration function of the tube.

Many attempts have been made to provide air vents that reduce the generation of vacuum while in bottles. Initial US Pat. No. 598,231 to Roderick has a baby bottle with a U-shaped tube. However, when lifting the bottle, the average baby left some liquid in the U-shaped tube. The remaining liquid blocked the tube so that the ambient air could not remove the vacuum in the bottle. As can be seen in US Patent No. 927,013 to Van Cleve, another patent demonstrates a related type of technology and provides a means for venting air from the interior of the vessel. In addition, US Pat. No. 1,441,623 to Daveport and US Pat. No. 2,061,477 to Perry show other means of venting air from a bottle.

In previous studies of this application, the venting and inner tubes of US Pat. No. 5,779,071 and US Pat. No. 5,570,796 prevent the formation of partial vacuum during sucking to prevent spilling. The '071 patent provides a vent tube extending into the bottle. The vent tube has a hollow cylindrical shape that protrudes sufficiently downward in the bottle. The '796 patent provides a reservoir positioned over the marking on the bottle. The reservoir communicates with a conduit system that exchanges sucked liquid with air from the reservoir, thereby preventing the formation of a partial vacuum in the bottle. Numerous designs of bottles are available in the prior art. In many cases, when nursing an infant, vacuum is frequently generated in the bottle while consuming the contents. When affected by this type of condition, it is believed that vacuum causes a variety of physical damage to infants. Vacuums generated within a bottle due to infant's sucking behavior can cause pressure imbalances at various body parts, such as the ear canal, leading to body fluids, ear disease, speech delays, delays in development, delayed development, illness, or other situations. Can be. Therefore, in order to prevent the creation of a vacuum inside the bottle, the presence of the bottle incorporating the aeration means has been considered a desirable development in the field of baby care products. This is disclosed in the Applicant's '071 Patent and' 769 Patent of Applicant, where the storage tube provided for venting out of the bottle cap near the top is partially or fully folded over into the vent hole while the contents of the bottle are consumed. It extends to the bottom of the container to function.

On the other hand, the present invention includes means for aeration of air pressure in the bottle, so that the bottle is vacuumed or pressured in the bottle regardless of whether it is used, stored in an upright position or partially or completely turned over while consuming the contents. To prevent the occurrence of.

Other U.S. patents relating to the subject matter of the present invention are U.S. Patent No. 189,691 to Brier, U.S. Patent No. 345,518 to Lelivre, U.S. Patent No. 679,144 to Hardesti, U.S. Patent No. 834,014 to Riquet U.S. Pat. US Pat. No. 2,744,696 to US Pat. No. 3,059,707 to Wilkinson et al., US Pat. No. 5,570,796 to Brown et al. In addition, British Patents 273,185 and 454,053 show related techniques.

The current technology overcomes the limitations of the prior art nipple aeration bottle. It is necessary to reduce the vacuum inside the bottle using the vent tube. That is, the tapered vent tube of the present invention limits the formation of a vacuum inside the bottle by allowing air to be expelled quickly and away from the tube and immediately returning the liquid to the reservoir. The enlarged adjacent portion of the vent tube minimizes the occurrence of leaks from the bottle. The present invention can be easily cleaned, withstands unintended chewing behavior and dissipates the pressure created by the chewing behavior. The present invention prevents leaks and continuously vents the bottle, thereby eliminating any air bubbles in the vent tube.

Accordingly, the present invention improves the vent tube inside the bottle by changing the shape of the vent tube. The vent tube generally has a contour shape, preferably conical shape with the diameter of the cone, which is predominantly larger and inferiorly smaller. The conical shape empties the liquid itself in the reservoir of the vent tube while pushing the air away from the bottle. The conical shape prevents liquid from entering the insert, thereby venting the bottle directly and preventing leakage of liquid from the bottle.

The present invention also provides an improved form of the vent tube to lower the internal pressure of the liquid and air. When pressure is applied to the bottle's milk and rises in the vent tube, the milk loses strength due to the widening characteristics of the vent tube in the upper wider. The larger diameter of the cone shape prevents the liquid in the bottle from propelling close to the tube of the insert and causing a leak. This is due to the larger diameter of the cone shape at the near end of the tube as compared to the far end, reducing the pressure of the compressed air and allowing the liquid to flow into the reservoir. By preventing the propulsion of liquid in the insert, the cone shape prevents leakage from the bottle.

In addition, the larger diameter of the conical section increases the capacity of the reservoir. When the infant emptyes the bottle and the liquid level drops below its maximum value, the liquid occupying the reservoir exits the reservoir more quickly and efficiently. When the caregiver or infant is upright, the liquid immediately exits the reservoir within the larger diameter of the conical tube and returns the remaining liquid to the bottle.

The present invention contemplates an infant and completes the movement of the air bubbles introduced by the infant's chewing action on the nipple to advance to the far end of the vent tube. The invention also moves the liquid (in front of the air bubbles) close to the reservoir of the vent tube. As intended, the vent tube functions in an automatic and continuous manner.

The present invention establishes structured relationships between containers or bowls and formulas in feeding bottles. Since the bottle is of sufficient size, the formula is prepared and placed in the container. A flowable surface is disposed below the vent port for directing the vent port or exterior of the vessel for venting purposes. Also, even when the container is turned upside down by the infant or caregiver during feeding, the liquid fluid does not approach the insertion vents remote from any position. Thus, the concept of the present invention is to provide a container with sufficient volume and volume, so that either 4 ounces, 6 ounces, 8 ounces, or whatever size range is supplied, the fluid or milk supplied is the same to achieve the characteristics of aeration for the bottle. Will remain in the vent port.

Therefore, no positive or negative pressure can be established in the container because the vent port is open for discharge purposes when the bottle is held in the upright direction. The preparation for feeding takes into account the aeration of negative pressure generated internally in the container resulting from the infant's sucking behavior, even when heated or heated, and even when the bottle is turned over during feeding.

The feature of providing the container with sufficient internal volumetric size is achieved through the use of a container having a large spherical shape or cylinder and having excessive dimensions such as flattened on each surface or having a size equivalent to the size of the Mason bottle. In yet another embodiment, the container is cylindrical but flattened on the side. In other embodiments, the container may be in the form of a bottle or may include some cavities on the sides of the container to facilitate lifting. In addition, when the spherical or cylindrical of the container is used, it may have a flat bottom to add stability to the bottle when placed on the surface.

In a preferred embodiment, the vent port in the insert cooperates with a vent tube in place, a lateral vent slot made in the insert fixed to the top of the vessel by a threaded collar holding the insert, a vent tube in the vessel and a conventional nipple. do. The vent port in the insert associated with the vent tube can open straight up and down in the vessel and prevent the infant fluid from entering the vent tube and provide a lateral port on the side to enable venting when the vessel is flipped during use. Can have

In other embodiments, the container, collar and nipple may be in conventional form and have a volumetric size from the shaped container as described above. However, since the vent port is opened to drain the contents when the bottle is held in the upright direction, the vent tube and port in the insert are directed through the surface of the container rather than cooperate with the collar in the same manner as described in the '071 patent. Can be stretched out.

Nevertheless, in the manner described above, the entry and exit of the vent port leading the vent tube, regardless of what form or structure the container possesses, so that the infant fluid is below or above the vent port when the bottle is placed or flipped during use. The orientation of the vent ports at the points may be arranged in the direction of the center of the shaped container.

Accordingly, it is an object of the present invention to provide a new and improved vent tube for infant bottles.

It is another object of the present invention to remove the pressure on the liquid phase of the bottle which stops leakage by preventing the introduction of liquid into the insert.

It is another object of the present invention to provide immediate release of air bubbles when the bottle is upside down.

It is another object of the present invention to immediately empty the liquid from the reservoir by providing a clear increase in the volume of the reservoir caused by the large diameter of the conical shape.

During the period of use for feeding the infant or during the period of nonuse during which the bottle is placed at its base, during storage, heating or rest, the venting port in the insert may be out of range from either liquid or milk contained in the container. It is an object of the present invention to provide a container of a capacity size for use as a feeding bottle integrating an insert with a vent tube arranged centrally.

It is an object of the present invention to provide rescue means in a bottle which provides continuous aeration of pressure or vacuum generated in the container, with or without the bottle.

Finally, it is an object of the present invention to provide a structure of a wide rim or other sized collar that, when structured in a baby bottle, is used with standard wide mouse containers and useful for feeding infants a formula.

These objects will be apparent to those skilled in the art in view of the present invention and the study of the description of the preferred embodiments as set forth below in connection with the drawings.

The present invention overcomes the limitations of the prior art by providing a fully ventilated wide rim or other sized bottle with a tapered vent tube that removes vacuum in the vessel and prevents leakage from the vessel. Referring to the drawings, in particular Figures 1 and 2, a fully ventilated, wide rim, or other sized bottle prior to the present invention is disclosed. It comprises a spherical container 1 having a sufficient volume capacity in the container to achieve studying the results of the present invention. In other words, when the infant formula of reference numeral “2” is placed in the container so as to be generally suitable for the amount of food to be supplied to the infant, the container is filled with the water level below the bottom of the vent tube 3, more specifically, the insertion. Distance from the sieve and vent port 4.

Thus, when the bottle is being heated and the pressure is increased in the vessel, the atmosphere is open due to the opening of the vent port 4 of the distal insert which, however small, will absorb the generated pressure and allow it to vent out of the illustrated bottle. As soon as it is ventilated. The nipple 5, threaded collar 6 and vent insert 7, which are threaded on the upper edge of the container 1, are preceded by the '071 patent with the exception that these components are manufactured in wider dimensions. Standard volume levels of fluids that are all manufactured in the manner described and fit into structures and inserts, such as inserts and vent ports, even though standard nipples are adopted by fitting to the wide rim style of the opening for the container 1 shown. Provide a form of sufficient volume capacity for the bottle to achieve the relationship between. It allows to achieve the advantageous effects of the present invention during use. In addition, as previously discussed, when the bottle of the present invention is turned upside down to feed food to an infant, the fluid may occur on opposite sides of the inverted container 1, but below the end insert and vent port 4 By having a surface level of water, the sucking action caused by the infant during food feeding and the formation of a vacuum or partial vacuum in the container during food feeding through the vent tube 3 to the outside of the vent insert 7 It is continuously vented by (4). The container 1 of the present invention has a small flattened surface 8 at the bottom of the container to freely stand the bottle when not in use, when heated or warmed during storage or in preparation for consumption of the liquid content. Include.

FIG. 2A shows the method of feeding the container 1 and food to disclose a method of maintaining the fluid level 2 below the open vent port 4 so as not to block the venting of the partial vacuum generated in the container during the food feeding process. Shows a bottle of upside down container.

3 and 4 are in the form of a container 9 for feeding bottles with further modifications in which the vent tube 10 is integrally formed with the bottom 11 of the container with the vent port 12 positioned at the center of the container. The modified example is shown. Thus, irrespective of where the container 9 of this bottle is attached, the liquid surface level 13 for the purpose of venting out of the bottom opening of the container shown is air in the vent port 12. Do not disturb the flow of water. This does not matter whether the container 9 can be positioned vertically or flipped over as shown in FIG. 3 during storage or eating. In this particular case, the threaded collar 15 and the nipple 16 are conventional and have a wide rim 17 of the container 9 in order to increase the volumetric capacity of the bottle and to obtain the desired and required result for a particular development. And screw them together. In addition, the structure of the wide rim container 9 is generally spherical as shown in Fig. 3, but is flat on the front and rear surfaces as shown in Fig. 4 so that it is flowable as desired and required for this development. Volumetric capacity is obtained.

5 and 6 provide a back and top view of the modified bottle as described previously in FIGS. 3 and 4.

7-9 illustrate a modified feeding bottle of the present invention wherein the vessel 18 has a mason vessel style, such that a vent tube 20 is screwed onto the screws 24 of the vessel shown, A wide rim 19 style of opening for receiving the reservoir portion 25, the vent insert 21, the nipple 22 and the threaded collar 23 is supplied to the upper end. Components 20 and 23 and 25 are described in the '071 patent with the exception that the components are manufactured in wider dimensions for being received on the wide rim opening 19 of the container 18. It is very similar in terms of components and structure.

The vent tube communicates with an upper internal reservoir portion 25 that forms a reservoir-like shape, which is located on and within the inner vent tube 26 of the vent insert 21 and described in the '071 patent. It works in the same way. In this particular case, however, since it is mounted on the wide rim of the volume vessel 18 at the time of insertion, in order to achieve the advantageous effects and results as described for the present invention, the vent port 27 of the vent structure is It is arranged approximately in the center of the internal space of 18). Therefore, the liquid surface level 28 being filled in the vessel is always below the entrance to the vent port 27, so that the vessel is tilted or flipped at any angle, as shown in FIG. Whether it is placed on the side or in any position during the food feeding process, it is possible to avoid the disturbance by the liquid. This ensures that there is always aeration into the atmosphere so that the pressure generated in the container during feeding with the bottle is reduced. In addition, there is an indication in the review process of the '071 patent. In order to achieve the objects and advantages of the present invention, such a vent tube and vent insert structure is inserted on the wide rim and held in place by the collar 23 so that ventilation is always provided, and the end insert and vent tube Reference numeral 26 internally communicates with the side vent passage 29 and opens to the atmosphere inside the collar 23.

As shown in FIG. 8, the side of the vessel 18 may be integrally concave as in reference numeral 30. This is to hold or hold a larger bottle during use.

10-13 disclose a larger dose sized feeding bottle with a generally rectangular shaped container 31. The installation has a wide rim opening 32 for receiving a collar 33, a supported nipple 34, a vent tube 35 and a vent insert 36.

The vent insert is shown in detail in FIGS. 14 and 15. The bottom of the vent port 37 is open and the vent is through a side vent 38 extending forward and backward of the vent tube to achieve vent from the interior of the vessel. In addition, the side vents 38 are approximately disposed at the midpoint of the volume of the bottle. In addition, when the bottle is turned over during feeding, the side vents 38 prevent entry of the fluid 39. Nevertheless, as shown in Fig. 13, the liquid level is always at a position spaced from the bottom of the vent tube 35 to achieve the object of the present invention. Also shown in FIG. 15 and as can be seen from the '071 and' 796 patents, the vent insert 36 to allow for the release of atmospheric pressure, ie, a vacuum or pressure generated within the bottle during use outside of the bottle. ) Has a side vent 38 in communication with the vent tube 35 to achieve the advantageous effects and results of the present invention.

Fig. 16 discloses a spherical form of a bottle, in which the container 61 of the bottle is mounted to the wide rim 62 by screwing the collar 63 and the nipple 64 together.

In this case, the vent tube 65 extends upwardly integrally from the bottom of the container 61, integrally ventilates in the atmosphere outside the bottom of the bottle, and has a side vent port 66 at the top of the vent tube. It is provided. This vent port is also arranged at approximately an intermediate point of the volumetric capacity for the vessel in order to achieve the advantages of the present invention.

18 and 19 disclose a variant of the feeding bottle of the present invention, wherein the container 51 of the feeding bottle has a generally rectangular shape in one dimension, but has an elliptical shape 52 when viewed along a vertical arrangement. The collar 53 supports the vent insert 55 against the nipple 54 and the wide rim 56 of the unitary container 51 against the bottle. The distal insert and the vent tube 57 extend downward and include an extended vent tube 58 so that at the bottom end the vent port 59 is approximately positioned at the volume midpoint of the container 51 for the bottle. . Thus, as shown in FIG. 19, the fluid 60 contained in the container for feeding is always under the arrangement of the vent port 59, whether the bottle is upright or turned over during feeding.

Figure 20 illustrates a bottle in a style similar to that of Figure 16, but in this embodiment, the container 47 is formed integrally with a flattened bottom 48 and an aeration tube 49 extending upwardly. have. The upper end 50 of the vent tube forming the vent port is disposed at approximately the volumetric midpoint of the vessel.

21 to 25 show a modification of the apparatus of the vent tube of the present invention. In Figure 21, the bottle has a container 67, a threaded collar 69, and a nipple 70 mounted on a wide rim 68. For venting purposes, in this particular embodiment, the vent tube 71 is integrally formed with the vessel 67 and extends radially inwards along an inclined slope at approximately an intermediate point of the vessel. The vent tube has a vent port 72 disposed at a generally midpoint position.

Thus, the flow 73 provided in the container in an amount generally fed to the infant is always below the entrance to the vent port 72 and does not cause leakage of the flow. It does not matter whether the bottle is stored or turned over during use.

22 shows a hemispherical style container 74 for a baby bottle. The bottle has a wide rim 75 and a threaded collar 76 and a nipple 77 are attached to the wide rim.

In an embodiment, a vent tube 78, similar to the vent tube of a baby bottle as described in FIG. 21, is integrally formed with the vessel, and the vent port (integral to the approximately volume midpoint of the vessel is integrated to achieve the advantages of the present invention). 79) and more specifically inclined arrangement in the vessel to place the lateral port 80.

Figure 23 is similar to a baby bottle structured as described in Figure 21, but in this embodiment the container 81 is arranged below the side of the container and opened 83 to the atmosphere and provided at approximately mid-point of the container 81. With a vent tube 82 having a port 84

Figure 24 illustrates a structure for a bottle similar to a bottle as described above in Figure 22, but in this particular embodiment the container 85 has a vent tube 86 formed integrally below the side 87 of the container. . This may be structurally adopted by the attachment of the flange 88 to the opening 89 formed integrally or provided through the wall of the container 85. In order to achieve the advantages and effects of the present invention, the inner end of the vent tube 86 has a vent port 90 disposed approximately at the volumetric midpoint of the vessel.

25 and 26 disclose further modifications to the feeding bottle of the present invention, as shown in FIG. 26, the rectangular container 91 has an oval appearance 92 when viewed along the vertical direction.

In order to provide sufficient volume capacity, the fluid surface 93 added to the container is always below the vent tube 94 and vent port 95 regardless of the position occupied by the bottle in use. According to the structure of the ventilation characteristic of the present invention, as shown in Figs. 25 and 26, the vent tube 94 extends laterally from the side of the vent insert 97 by passing through the shape threading 101 and the container A side vent 96 is provided that provides for venting any pressure or vacuum developed within 91 to the atmosphere.

As can be seen from the '071 patent and the' 796 patent, the vent insert 97 includes a series of support vanes 98 that provide an intermediate space 99 and flow through the bottle when the bottle is turned upside down during feeding. . However, the lateral vent 96 communicates with the vent tube 94 allowing or disallowing any pressure to pass therethrough. The lateral vents are vented to the atmosphere by passing through an incomplete seal formed by threaded connections between the collar 100 of the bottle and the threaded portion 101 of the wide rim structure of the container 91. Nevertheless, the criticality of the location of the vent port 95 at approximately the volumetric midpoint of the vessel 91 is essential, so that the bottle is used, stored, heated or fed by preventing leakage from the vessel when the fluid is filled in the vessel. Even if it is upside down, aeration can occur effectively.

The bottle component shown in Figure 27 shares similarities with the bottle assembled earlier in Figures 13-15. 27 is an exploded view of fewer components than a liquid container or bottle. The nipple 115 extends outward from the collar 116 secured to the baby bottle 1. Between the collar and the bottle, the vent insert 117 grips the rim of the bottle. The vent insert has a generally hollow cylindrical shape with a low height peripheral wall 123. Across the diameter, the vent insert 117 has a side vent 119 having a center hole in the direction of the bottle as shown in Figs. 27A and 27B. The side vents have two opposing openings 118 which are generally in communication with the air between the bottle 1 and the atmosphere. As shown in Figure 27B, the insert 117 has a large lip 121 and a small lip 122 concentric with and slightly below it. The vent insert 117 has an adjacent hollow cylindrical shape but a larger diameter than the vent insert and has a large lip 121 suspended from the wall 123. In this way, the aeration insert can be applied to a tight seal within the rim of the bottle during installation, thereby preventing leakage from the aeration insert rather than the air aeration required from the application and use of the insert and the bottle. prevent. Although this hole may be of other shapes, a preferred embodiment is provided with reference numeral 114 for the contoured vent tube 113 shown as conical. In addition, in an embodiment, the bottom of the vent tube is completed so as to be close to the inner bottom of the bottle that the vent structure of the present invention employs, whether it is a standard bottle or a wide rim bottle. The large lip has a circumferential bulge 124 of slightly larger diameter than the large lip. The bulge of the large lip seals the insert against the inside diameter of the bottle. The large lip has an outer diameter relative to the inner diameter of the bottle. As viewed from the side vent 119, the vent insert 117 has a hollow cylindrical shaped small lip 122 of smaller diameter than the large lip. The small lip has an outer diameter of the inner diameter of the reservoir. The small lip seals the reservoir 126 of the vent tube of the present invention against the vent insert 117.

The vent tube 113 has a generally hollow cylindrical reservoir 126 having an open top 127 and a partially closed bottom 128. The bottom is smoothly rounded away from the top. At the center of the bottom 128, the hole 129 provides a passage to the vent tube 113 connected to the bottom. The vent tube forms a hollow truncated cone shape with a large diameter portion 130 positioned toward the reservoir 126 and a narrow diameter portion 131 positioned away. The large diameter is 0.60 inch (1.524 cm) and the narrow diameter is 0.30 inch (0.762 cm).

Coaxially with the vent tube 113, the vent insert 117 is a distal insert perpendicular to the side vent 119 opposite the insertion wall 123 centered on the hole of the side vent 119. Or inner vent tube 120. The inner vent tube 120 is a hollow cylinder of length beyond the diameter. The inner vent tube 120 communicates with air but does not supply the liquid of the present invention from the side vent 119 into the reservoir 126 of the vent tube 113.

FIG. 28 shows only the vent tube 113 having a large diameter 130 close to and similar in diameter to the bottom 128 of the reservoir 126. The vent tube 113 tapers away toward the narrow diameter portion 131. In a preferred embodiment, the large diameter portion 130 is approximately twice as large as the narrow diameter portion 131 at a ratio of about 2: 1.

29 also illustrates a vent tube 113 having a larger diameter portion 130 that is substantially smaller than the previous embodiment. In this embodiment, the large diameter portion 130 is at least 1/8 times larger than the diameter of the narrow diameter portion 131. Towards the narrow diameter portion 131, the vent tube 113 is tapered away as before. In this embodiment, the large diameter portion 130 is slightly larger than the narrow diameter portion 131 at a ratio of about 1.1: 1.0.

30 shows a prior art feeding bottle in use by an infant chewing the nipple with the feeding bottle tilted down a horizontal orientation while being held by the infant. This feeding bottle 1 has a cylindrical tube of constant diameter. In the bottle tilted down, the tube is in contact with the feeding liquid. By chewing, when the nipple is rapidly compressed, the compressed air above the liquid compresses the liquid in the container. The compressed air travels from the nipple through the vanes of the insert into the container to compress the liquid. Compressed air forces liquid up into the prior art vent tube that is straight and has a constant diameter wall. The liquid in the vent tube suddenly enters the insert and exits the bottle through the side port of the insert. Thus, the discharged liquid leaks to the infant or caregiver.

The tapered vent tube of the present invention shown in FIG. 31 disperses the conveyed liquid introduced into the vent tube. Contour tubes, in particular conical tubes, distribute the pressure acting on the liquid in the tube because the tube diameter expands to allow the liquid to be conveyed to flow smoothly in the reservoir instead of suddenly leaking out of the vent port as in the prior art. The bottle 1 of FIG. 31 has a vent tube that increases in diameter from the conical, ie narrow distal end 131 to the wide proximal end 130. The infant chewing the nipple 5 compresses the liquid 2, but due to the increasing diameter of the vent tube, the increasing volume of the inside of the vent tube is reduced and the conveyed liquid 2 is transferred from the insert 119 to the bottle ( Release from 1) prevents leakage to the outside of the collar 6. Since the increasing diameter of the vent tube limits the increase in pressure in the bottle 1, leakage from the bottle is prevented by the present invention.

From the above description, fully ventilated wide rims or bottles of different diameters have been described. Such bottles can reduce the increase in pressure in the vent tube to prevent leakage from the bottles. These bottles and various components can be made from many different materials, but are not limited to polymers, low density polyethylene, high density polyethylene, polypropylene, glass, nylon, ferrous and nonferrous metals, alloys and mixtures thereof.

Variations and modifications to the technical subject matter of the present invention can occur to those skilled in the art by reviewing the development as described herein. Within the scope of this development, modifications are included within the principles of the present invention. The description of the preferred embodiment and the illustrations of the drawings merely illustrate exemplary purposes.

The present invention improves the vent tube inside the bottle by changing the shape of the vent tube. The vent tube generally has a contour shape, preferably conical shape with the diameter of the cone, which is predominantly larger and inferiorly smaller. The conical shape empties the liquid itself in the reservoir of the vent tube while pushing the air away from the bottle. The conical shape prevents liquid from entering the insert, thereby venting the bottle directly and preventing leakage of liquid from the bottle.

The present invention also provides an improved form of the vent tube to lower the internal pressure of the liquid and air. When pressure is applied to the bottle's milk and rises in the vent tube, the milk loses strength due to the widening characteristics of the vent tube in the upper wider. The larger diameter of the cone shape prevents the liquid in the bottle from propelling close to the tube of the insert and causing a leak. This is due to the larger diameter of the cone shape at the near end of the tube as compared to the far end, reducing the pressure of the compressed air and allowing the liquid to flow into the reservoir. By preventing the propulsion of liquid in the insert, the cone shape prevents leakage from the bottle.
