Abstract

A nursing bottle formed of a large volume container, incorporating a vent tube that extends to vent pressure at all times. The nursing bottle may have a cylindrical shape or other configuration that prevents formula placed therein from blocking the vent tube regardless of its angular disposition. The vent tube extends distally from the vent insert, operatively associated with a collar, that holds the vent structures and the nipple to the wide rimmed opening. In addition, the vent tube has a conical shape of decreasing diameter distally toward the center of the bottom to dissipate the pressure that may cause leakage from the bottle. Further, the vent insert has a major and minor seal that prevents leaks out of the collar and onto an infant.

Description

The broad edge feeding bottle of ventilation fully with contoured vent tube

Technical field

The broad edge feeding bottle of ventilation fully with given shape (contoured) breather relates generally to articles for babies.More specifically, the present invention relates to the feeding bottle of pipe in having, said interior pipe prevents the vacuum in the bottle and helps the baby from bottle, to suck liquid.

Background technology

Unique aspect of the present invention is the enlarged diameter of breather, and it is using and depositing the ventilation completely that breather is provided in the process.

The baby has the instinct of sucking milk from their mother there.But because a variety of causes, the baby is often from other source of supply drinkable liquid.The baby lacks the ability of from simple glass bottle and cup, drinking and not overflowing.Therefore, use breast bottle or feeding bottle to feed to baby's liquid.Feeding bottle is characterised in that with silicones, latex, rubber or other material as nipple, nipple has the hole and is fixed to the opening that crosses baby bottle top at its tip.At present feeding bottle uses through following obtaining: with liquid be full of feeding bottle, insert breather, fixedly nipple, inversion feeding bottle, place baby's mouth and baby to drink liquid nipple from nipple.

The feeding bottle of nipple edge ventilation is by closely sealing, but nipple is an opening.When nurture during the baby, liquid volume reduces in the bottle, and the vacuum in the bottle increases pro rata, thereby has polluted liquid.But when the baby sucked, breather allowed surrounding air to get into bottle and is positioned at the liquid back substantially.Breather has reduced any vacuum that in bottle, produces owing to baby's sucking.Breather has improved liquid and has flowed out from nipple, and the baby is sucked more easily.The danger that makes the baby face littler suction air and cause suffering from abdominal pain.

At first, the Infants'feeding container have up, attached on it narrow and small mouthful of nipple.The nursing staff notices that narrow and small opening has hindered rapid inside near feeding bottle, and makes feeding bottle inside be not easy to clean.Manufacturer has then overcome said defective with the bottle that has than the major diameter opening.These feeding bottles have been obtained on market and have been sold successfully.

Bigger opening need be made and use the nipple and nursing mouth that has than larger diameter flange, so that cooperate with the opening of feeding bottle.Larger-diameter flange has prevented that nipple is engaged to the position appearance leakage of feeding bottle.But, with the upper end of nipple and bottom keep same distance, larger-diameter nipple has the bigger volume that nipple holds.

And although nipple is design to be used for sucking with liquid removing from feeding bottle, the baby often chews nipple.Therefore, nipple is fed adnexa with other and is had tough and tensile design and chew with opposing.Chewing there being feeding problem of nipple, for example neurological postpones or the baby of defective is more frequent.Neurological postpones to cause the frequent chewing of baby when object is placed in the mouth, chews nipple usually.

To feeding nipple, particularly those have than frequently the chewing in the process of the nipple of major diameter and internal capacity, and the baby is pushed into the air of far-end in the feeding bottle self.The air that is incorporated in the feeding bottle can increase the feeding bottle pressure inside.Increased pressure often is pushed into the breather that is arranged in feeding bottle with the liquid of far-end.Liquid under the pressure passes ventilation insert and breather, leaves feeding bottle and liquid is overflowed from feeding bottle.

Because chewing the leakage that causes also takes place when the air of introducing is parked in the centre position of cylindrical shape breather.Because the pressure in the cylindrical shape breather, some liquid can be chewed the bubble that causes through the baby and caused in the breather.Ideally, be inverted and be in baby's nursing position and must be discharged from when entering in the pipe at feeding bottle when bubble usually.

But, capture the far-end that bubble in the breather makes liquid in the distal portions of breather can not pass breather and is drawn out to feeding bottle.Liquid fails to enter into the increase reservoir part of feeding tube, so that suitably discharge through breather.Nursing liquid then can hinder the ventilatory function of pipe.

Done many trials the feeding bottle with passage is provided, in order to reduce the vacuum that produces in the sucking process.The early stage patent No.598 that authorizes Roderick, 231 provide a kind of feeding bottle with U-shaped pipe.But general baby is when lifting feeding bottle, and some liquid residues are in the U-shaped pipe.Residual liquid has stopped up breather and has stoped surrounding air to discharge any vacuum in the feeding bottle.Other patent shows the technology of correlation type, and as appreciable in the United States Patent(USP) No. of authorizing VanCleave 927,013, the device that is used for from the internal tank air-out is provided.In addition, authorize the patent No.1 of Davenport, 441,623 and the patent No.2 that authorizes Perry, 061,477 patent illustrates other device of air-out in the feeding bottle.

In these applicants' previous work, promptly at patent Nos.5, in 779,071 and 5,570,796, pipe has prevented in sucking process, to form partial vacuum and prevented to overflow in the ventilation.' 071 patent provides a kind of breather that extends in the bottle.Said breather has the drum of hollow, and puts in the bottle fully downwards.' 796 patent provides and has been positioned at bottle reservoir (reservoir) of scale top.Said reservoir is communicated with conduit system, so that use the liquid of sucking from the air displacement of reservoir, thereby prevents in bottle, to produce partial vacuum.The feeding bottle that has multiple design in the prior art is available.In many cases, in the process of the content that distributes bottle, promptly when feeding the baby with milk, produce vacuum through regular meeting in the bottle.When the baby stood this situation, vacuum was considered to cause each the physiology's infringement to the baby.Because the vacuum that baby's sucking produces in bottle can cause the unbalanced pressure of the position at a plurality of positions (for example in the auditory meatus) at health, this can cause fluid infection, delayed speech, nervus motorius delay, development delay, sick or other predicament of ear.Therefore, provide and comprise that breather is to prevent that vacuum feeding bottle is considered to ideal development in the articles for babies field in bottle.This can find out in the applicant's ' 071 draw of patent formerly ' 769; The reservoir that is used to ventilate pipe wherein is provided; It is near the bottle cap outside is arranged in top and extend to the lower part of container so that partially or even wholly be inverted at bottle, when its content is consumed as passage.

On the other hand; This invention provides a kind of device, and this device is used to discharge any air pressure in the bottle, and is used for preventing producing any vacuum or pressure at bottle; And no matter said feeding bottle uses, deposits with stand up position, partially or completely be inverted in the still tolerant within it consumption process.

Other United States Patent (USP) that relates to theme of the present invention comprises the United States Patent(USP) No. 189,691 of authorizing Briere, the United States Patent(USP) No. 345,518 of authorizing Lelievre, the United States Patent(USP) No. 679,144 of authorizing Hardesty, the United States Patent(USP) No. 834 of authorizing Lyke; 014, authorize Donaldson United States Patent(USP) No. 1,600,804, authorize the United States Patent(USP) No. 2,156 of Schwab; 313 and No.2,239,275, authorize the United States Patent(USP) No. 2,610 of Gits; 755, authorize Panetti United States Patent(USP) No. 2,742,168, authorize the United States Patent(USP) No. 2 of Blackstone; 744,696, authorize the United States Patent(USP) No. 3,059 of Wilkinson; 707, authorize the United States Patent(USP) No. 5,570,796 etc. of Brown.In addition, BP No.273,185 and No.454,053 illustrates relevant research and development.

Present technique has overcome the restriction of prior art for the feeding bottle of nipple ventilation, wherein need use breather to reduce the vacuum in the feeding bottle.Promptly in technology of the present invention, the breather of tapered allows air to discharge fast and away from breather and liquid, so that be back to reservoir rapidly, in feeding bottle, forms vacuum thereby limited.The near-end of the increase of breather minimizes the incidence rate that feeding bottle leaks.The present invention cleans easily, can tolerate the pressure of chewing unintentionally and disperseing to produce owing to chewing.The present invention has prevented to leak and feeding bottle is ventilated continuously, thereby disperses any bubble in the breather.

Summary of the invention

Therefore, the present invention improves the breather in the feeding bottle through the shape that changes breather.Breather is roughly given shape, and preferably is embodied as conical by its shape, and wherein the diameter of cone is either large or small.Conical by its shape makes the air admission of far-end in feeding bottle, at once liquid itself is emptied in the reservoir of breather simultaneously.Conical by its shape has prevented that liquid from entering in the insert, thereby feeding bottle is ventilated at once, and has prevented that liquid from leaking from feeding bottle.

In addition, the invention provides the breather that improves shape, to reduce the internal pressure of liquid and air.The pressure transmission that reduces that causes owing to the nipple compression in the proximal end of widening of breather should obtain noting.When pressure is applied to milk and milk in the feeding bottle and is increased in the breather, milk owing to breather at an upper portion thereof the characteristic of widening of relative broad range reduce its power.Thereby larger-diameter conical by its shape has prevented liquid in the feeding bottle and in near-end is discharged to the pipe of insert, has caused leaking.This is to have larger-diameter conical by its shape because the near-end of pipe is compared with far-end, thereby disperses compressed-air actuated pressure and allow liquid to flow in the reservoir gradually.In case the solution stopping body is pushed in the insert, said conical by its shape has prevented the leakage of feeding bottle.

And larger-diameter tapering part has increased the capacity of reservoir.The liquid level of inhaling empty feeding bottle and liquid as the baby descends and when being lower than maximum, liquid will occupy reservoir, thereby faster and more effectively be discharged to outside the reservoir.When nurture person or baby gripped feeding bottle vertically, liquid was discharged reservoir rapidly and is entered into larger-diameter conical pipe, and makes remaining liq be back to feeding bottle.

The present invention allows owing to the baby chews any bubble generation moment and whole the moving that nipple is introduced, so that enter into the far-end of breather.And the present invention makes the liquid of bubble front move into the reservoir of breather to near-end.Breather is to work like desired automatic and successive mode thus.

Set up structural relation between the milk replacer of the present invention in container or vessel and feeding bottle.Feeding bottle has enough sizes to make milk replacer in container, be produced and is deposited in the container, and the surface arrangement of milk replacer becomes to be lower than towards external container directed blow vent or passage, to be used to the purpose of ventilating.In addition, even in the nursing process, by baby or nurture person vessel are inverted, liquid formula still can be near the far-end insert of any position.Therefore; Design of the present invention provides a kind of have enough volumes and volumetrical container; So that milk replacer or milk no matter with four ounces, six ounces, eight ounces still any big or small rank supply in the container; To always let determined blow vent expose, so that always obtain to be used for the ventilation attribute of feeding bottle.

Therefore; In container, can not form considerable malleation or negative pressure, this is because remain on vertical direction when feeding bottle, simultaneously by warm or heating so that for feeding when preparing; Even and feeding bottle is when being inverted in the nursing process; Blow vent will be opened, and to be used to the purpose of ventilating, any negative pressure that therefore allows to produce in inside owing to baby's act of sucking in the container is discharged from.

Provide the characteristic of the internal capacity of enough sizes to have very large-sized container to container and realize through use, for example bigger spherical shape, perhaps drum and each surface are straight, perhaps size equates with Mason's bottle (Mason jar).In one case, container can be spherical form.In another embodiment, container has drum, but its side is straight.In another embodiment, container can be doleiform, even comprise depression conveniently to lift in its side.In addition, when using sphere or cylindrical vessel, this container can have straight bottom, is used for when feeding bottle is shelved on the surface, increasing the stability of feeding bottle.

In a preferred embodiment; Blow vent in the insert and breather, the conventional nipple that is formed at horizontal communication groove, the breather in the container in the insert and is in the appropriate location match, and wherein said insert keeps the thread ring of insert to be fixed to the top of container through continuous being used to.Being positioned at the blow vent that links to each other with breather of insert can be directly and lead to container downwards, and each side can have lateral port, enters into breather to prevent any milk replacer, and ventilates when allowing container in use to be squeezed.

In another embodiment; Container, the collar and nipple can be traditional types; But has volume size like the forming containers of previous explanation; But breather and the extensible surface of passing container of passage in the insert, rather than with ' 071 patent that before existed in the same way as described cooperate with the collar.

But; At breather entrance place and the location of the blow vent of guiding breather can be arranged in the somewhere of structure container center; And tubular container can not have what kind of profile or structure; Thereby static or at feeding bottle owing to using when being inverted, can allow milk replacer to be below or above blow vent with the identical mode of previous explanation.

Therefore, the purpose of this invention is to provide a kind of new and the improved breather that is used for baby bottle.

Another object of the present invention is to disperse the pressure on the liquid in the feeding bottle, in case the solution stopping body is introduced in the insert, thereby has prevented leakage.

Another purpose of the present invention is when feeding bottle is inverted, and bubble is discharged at once.

Another purpose of the present invention provides the container that a kind of volume that causes owing to larger-diameter conical by its shape obviously increases, thus can be from container evacuation of liquid at once.

Another purpose of the present invention provides a kind of container of certain volume size; This container is as feeding bottle and have breather; Said breather has the insert that approximately is arranged in its center, thereby no matter be in the use when feeding infant, in the non-use when still container is located with its bottom; For example in depositing process, be heated or when static, the blow vent in the insert has all prevented to be contained in any milk replacer or the covering of milk wherein.

A purpose more of the present invention is that a kind of constructing apparatus is provided in feeding bottle, and said constructing apparatus is discharged any pressure or the vacuum that produce in the container continuously, no matter feeding bottle is also be in the non-use using.

At last, another object of the present invention is that the structure for broad edge or other size provides the collar, and this collar uses with the standard large container in being configured to feeding bottle the time, and is used for feeding infant.

The specific embodiment

The feeding bottle of broad edge or other size of present technique through ventilation is provided has fully overcome the restriction of prior art, and this feeding bottle is provided with the breather of convergent, in order to eliminate the vacuum in the container and to prevent the leakage of container.With reference to accompanying drawing, particularly Fig. 1 and 2 discloses the aforementioned broad edge of ventilation fully of the present invention or the feeding bottle of other size.Said feeding bottle comprises spherical container 1, in container, has enough volumes, thereby realizes very popular result of the present invention.Just; When for example milk replacer 2 is applied in the container and said milk replacer when applying for baby's feeding volume with regular supply; Said milk replacer is filling containers to the liquid level of the bottom that is lower than breather 3 only; And more specifically, as what can notice, said milk replacer is away from insert and blow vent 4 thereof.

Therefore; When feeding bottle is heated; Just in its container, form any pressure, because the blow vent 4 of far-end insert is in open mode, therefore said pressure will be discharged in the environment at once; With any pressure (no matter how little said pressure is) that absorb to produce, and allow said pressure be discharged to shown in the external environment condition of feeding bottle.Nipple 5, thread ring 6 and the ventilation insert 7 that is applied to the top edge of container 1 with screwing with ' 071 patent that before existed in the same way as described make; Except following aspect; Be that these parts are made and have wideer size; So that on the opening of the broad edge style of container shown in being assembled to 1; Even adopt standard-sized nipple that the feeding bottle of enough volume type also can be provided for feeding bottle thus, realizing feeding bottle member (for example insert and blow vent thereof) and in use to put on the relation between the milk replacer liquid level of any standard supply in the feeding bottle, thereby realize advantage of the present invention.In addition, when feeding bottle of the present invention was squeezed with feeding infant, milk replacer can be elevated to the opposite side of inverted container 1; But its surperficial liquid level will be lower than far-end insert and blow vent 4 thereof; Like this, any sucking action that in the nursing process, produces by the baby, and in the nursing process, be formed at any vacuum or the partial vacuum in the container; To discharge continuously through breather 3 and by its blow vent 4, and as aforementioned, be discharged to outside the ventilation insert 7.What should be noted that is, container 1 obviously of the present invention comprises the less flat surface 8 that is positioned at its bottom, is not using, deposits, or can freely stood during with the milk replacer content of ready-to-consume feeding bottle by warm or heating to allow feeding bottle.

Fig. 2 A illustrates container 1 and the feeding bottle thereof when being inverted in the nursing process, how will keep below the blow vent of opening 4 thereby disclosed fluid level 2, so that in the nursing process, do not hinder the discharge of any part vacuum that produces in the container.

A kind of modification of the shape of the container 9 of feeding bottle shown in Fig. 3 and 4 discloses, wherein further modification is: breather 10 with shown in the bottom 11 of container integrally construct, its blow vent 12 is arranged on the center of container substantially.Therefore, no matter where the container 9 of this feeding bottle possibly be in, the surperficial liquid level 13 of milk replacer can not hinder any air flow to enter into blow vent 12 so that discharge yet, shown in this example, being discharged to outside the bottom opening 14 of vessel.Tubular container 9 is not vertical location of that kind as shown in Figure 3 in depositing process, still in the nursing process, as understandable, is inverted, and is not always the case.In this particular example, thread ring 15 is conventional with nipple 16, and they are threaded into the broad edge 17 of container 9, so that in use increase the volume of feeding bottle, and is used to obtain the desired result with needs of these specific research and development.In addition; Like what can notice among Fig. 3, the structure of broad edge container 9 is roughly sphere, but disclosed like Fig. 4; Broad edge container 9 is straight with the back at its front surface on the surface, and still realizes the volume of milk replacer the desired and needs like these research and development.

Fig. 5 and 6 provides the rearview and the vertical view of the feeding bottle of the modification shown in previous Fig. 3 and 4.

Fig. 7 to 9 illustrates the feeding bottle of further modification of the present invention; The structure of the container 18 of feeding bottle wherein with Mason's bottle style; Thereby the end provides the opening 19 of broad edge style above that; Be used to hold breather 20, acceptance division 25, ventilation insert 21, nipple 22 and thread ring 23, shown in they all are threaded on the screw thread 24 of container.Parts described in ' 071 patent that these parts 20-23 and 25 structurally with before exists are closely similar, except these parts are manufactured into the size of broad, so that on the broad edge opening 19 of container shown in being accommodated in 18.

Receiving unit 25 is communicated with in breather and its top, thereby forms the structure of the similar reservoir of being mentioned, and 26 of the internal ventilation pipes of ventilation insert 21 on it with its in so that work with the same way as of being explained in ' 071 before in patent.But; In this particular example; What should be noted that is; Because all parts all are mounted to the broad edge of measuring volumetrical container 18, thus the blow vent 27 of ventilation member when it inserts, be arranged on substantially shown in the center of inner space of container 18 so that realize like advantage and result to the present invention laid down a definition.Therefore; The surperficial liquid level 28 that puts on the milk replacer in the container will always be lower than the inlet of blow vent 27; Thereby tubular container 18 is not to remain on resting position as shown in Figure 7; Still in the nursing process, work as the container lean certain angle,, be placed in its side or any position and all avoided the inlet of blow vent blocked if perhaps container is inverted.This allows in the process with bottle feeding, and the pressure that reduces that in container, produces always is discharged to surrounding.In addition especially when looking back ' 071 patent; What should be noted that is; These breathers are inserted on the broad edge and through the collar 23 with ventilation insert structure and remain on the appropriate location, and wherein far-end insert and breather 26 are communicated with horizontal communication passage 29 inner, and surrounding is led in the inside of the collar 23; So that always provide its ventilation, thereby realize objects and advantages of the present invention.

What in Fig. 8, it is further noted that is that the side of container 18 can have whole recess 30, is used for gripping and keeping in the use of container the feeding bottle of large-size.

Figure 10 to 13 discloses has bigger volumetrical feeding bottle, and this feeding bottle has the container 31 of the rectangular configuration of being roughly.Said container has broad edge opening 32, the collar 33 shown in this broad edge opening is used for when installing, holding, nipple 34, breather 35 and ventilation insert 36 that the collar supported.

Figure 14 and 15 illustrates in greater detail the ventilation insert, and can find out that the bottom of blow vent 37 is openings, and wherein ventilation is to realize through the transverse holes 38 that extends to the breather front and back, with realize from shown in the internal ventilation of container.In addition, transverse holes 38 approximately is arranged in the volumetrical centre position of feeding bottle (midpoint).In addition, when feeding bottle was inverted in the nursing process, transverse holes 38 had prevented that any milk replacer 39 from entering into wherein.But like what in Figure 13, can see, the liquid level of milk replacer always is positioned at and the place at a distance of a segment distance, the bottom of breather 35, to realize the object of the invention.And; Like what in Figure 15, can see; And like what notice the patent of ' 796 from ' 071 draw; Ventilation insert 36 has the horizontal communication mouth 38 that is communicated with breather 35, so that in use the interior any vacuum that produces of feeding bottle, pressure etc. are discharged in the outside environment of feeding bottle, to realize advantage of the present invention and result.

Figure 16 illustrates a feeding bottle, and this feeding bottle comprises hemispheric container 40, and has the collar 42, nipple 43 and ventilation insert 44 on the broad edge 41 of the integral body that is installed in container.In addition, breather 45 extends downward in the container 40, and likewise, the bottom 46 of breather approximately is arranged in the volumetrical centre position of feeding bottle, to realize advantage of the present invention.

Figure 17 discloses spheric feeding bottle, and wherein the container 61 of feeding bottle has and is threadably engaged the collar 63 and nipple 64 that is mounted to container broad edge 62.

In this example, breather 65 from the bottom integrated of container 61 extend upward and the inner environment that leads to outside the feeding bottle bottom, and the end has horizontal communication mouth 66 above that.And about centre position of vessel volume shown in these blow vents are arranged in is to realize advantage of the present invention.

Figure 18 and 19 discloses a modification of feeding bottle of the present invention, and wherein the container 51 of feeding bottle is roughly rectangular configuration on one dimension, but vertically arranges to have elliptical shape 52 along it.The collar 53 supports nipple 54, and ventilation insert 55 is inserted into the whole broad edge 56 of the container 51 that is used for feeding bottle.Said far-end insert and breather 57 thereof be to extending below, and comprise the breather 58 of extension, thus likewise, the blow vent 59 of breather its bottom approximately be arranged in shown in milk bottle container 51 volumetrical about centre positions.Therefore, always any milk replacer 60 that is used to feed that is contained in the container will be lower than the position of blow vent 59, and, still be as in the nursing process, being inverted no matter feeding bottle is that kind shown in figure 18 is upright static.

Figure 20 illustrates the feeding bottle with the similar style of Figure 16; But in this example; The container 47 of feeding bottle is formed with upwardly extending breather 49 in its straight bottom 48 integral body, likewise, and about centre position of vessel volume shown in the upper end 50 of the formation blow vent of breather is arranged in.

Figure 21 to 25 illustrates the various modification that breather of the present invention is arranged.As mentioned, in Figure 21, shown feeding bottle make its container 67 be installed in container broad edge 68, thread ring 69 and shown in nipple 70 on.For the purpose of ventilating, in this particular example, breather 71 and container 67 whole formation, and about centre position of container shown in extending radially inwardly to along an oblique angle, wherein blow vent 72 approximately is arranged on like mentioned position.

Therefore, any milk replacer 73 Infants'feeding amount, that offer in the feeding bottle will always be lower than the inlet of blow vent 72 usually, and can not cause any leakage of feeding bottle.No matter feeding bottle is stored still to be inverted in use and is not always the case.

The container 74 of the hemispherical style of feeding bottle shown in Figure 22 illustrates.Said feeding bottle has broad edge 75, and thread ring 76 is attached on this broad edge with nipple 77.

In this example; Similar with feeding bottle shown in Figure 21; Breather 78 forms with integral container, and is arranged in the container obliquely, so that with the blow vent 79 of breather; About centre position of internal tank, vessel volume shown in more specifically the horizontal communication hole 80 of breather being arranged in is to realize advantage of the present invention.

The feeding bottle of Figure 23 and structure shown in Figure 21 is similar; But in this example, like what can notice, the breather 82 of container 81 be arranged to shown in container side more downward; Lead to environment at 83 places, and the blow vent 84 of breather be arranged on shown in about centre position of container 81.

Figure 24 illustrates the structure that is similar to the feeding bottle of before in Figure 22, explaining, but in this particular example, breather 86 integral body of container 85 form shown in container side 87 more downward.This can wholely form, and perhaps structurally puts on container side through the opening 89 that flange 88 is adhered to the wall formation of passing container 85.Likewise, about centre position of vessel volume shown in the blow vent 90 of the breather of breather 86 inner ends is arranged in is to realize result of the present invention and advantage.

Figure 25 and 26 discloses the another modification of feeding bottle of the present invention, and wherein the container with rectangular configuration 91 of feeding bottle vertically has oval outward appearance, and this illustrates with 92 in Figure 26.

Said container provides enough volumes, always will be lower than breather 94 and blow vent 95 thereof so that be added into the surface 93 of the milk replacer in the container, and no matter the residing in use position of feeding bottle.According to the structure of the dimensional characteristics of these research and development and as in Figure 25 and 26, can find out; Breather 94 has the lateral horizontal communication pipe 96 that extends laterally to ventilation insert 97; And said breather is because the screw thread 101 through constructing; Can any pressure or the vacuum that form in the container 91 be discharged to environment, this can obtain understanding from previous patent.

As from ' 071 draw ' 796 patent known, the ventilation insert 97 comprise a series of support blades (supporting vanes) 98, this support blade provides intermediate space 99, when feeding bottle was inverted in the nursing process, milk replacer can flow through said intermediate space.But; Horizontal communication pipe 96 is communicated with breather 94; Thereby allow any pressure or insufficient pressure through said breather; Thereby the inadequate sealing that is threaded and forms between the screw thread 101 of the container 91 of the collar 100 through feeding bottle shown in the process and broad edge structure, and be discharged to environment.But; The criticality in the 91 volumetrical centre positions of container shown in blow vent 95 is positioned at substantially is essential; Milk replacer to prevent to put in the container leaks from container, thereby makes ventilation to take place effectively, and no matter feeding bottle is using, depositing, heats or in the nursing process, is being inverted.

Milk bottle member shown in Figure 27 is with previous similar at those parts that assemble shown in Figure 13-15.Figure 27 illustrates the decomposition view of the less parts of liquid container or feeding bottle.Nipple 115 stretches out from the collar 116 that is fixed to feeding bottle 1.Between the collar and feeding bottle, ventilation insert 117 is the edge of feeding bottle 1 promptly.The ventilation insert is roughly the drum of hollow, and it has the circle wall 123 of lower height.Cross diameter, ventilation insert 117 has horizontal communication hole 119, after state passage and have the centre bore shown in Figure 27 A, 27B towards the feeding bottle direction.The horizontal communication hole has two opening opposing 118, the air communication between said opening cardinal principle and feeding bottle 1 and the environment.Shown in Figure 27 B, insert 117 has big antelabium 121 with concentric and be positioned at the microcheilia edge 122 of big antelabium 121 belows slightly.Dangle from wall 123, the big antelabium 121 of ventilation insert 117 has successive hollow cylinder shape equally, but its diameter is slightly littler than the ventilation insert.By this way, the ventilation insert can be applied in the edge of feeding bottle by tight seal in its installation process, has prevented any leakage of ventilation insert thus, except the use of the required air ventilation of the structure of insert and its suitability and feeding bottle.This hole is arranged on 114 places, and with the breather 113 that is used for given shape, although said in a preferred embodiment hole is depicted as taper, other shape also is fine.In addition, in this example, the bottom of breather ends at ventilation device of the present invention usually and applies near the interior bottom portion of any feeding bottle on it, and no matter be standard feeding bottle, broad edge feeding bottle etc.Big antelabium has the circumferential protrusion 124 of somewhat larger in diameter in it.The convexity of big antelabium is sealed to insert the internal diameter of feeding bottle.The external diameter of big antelabium equals the internal diameter of feeding bottle.Dangle from horizontal communication hole 119, the microcheilia edge 122 of ventilation insert 117 is the hollow cylinder shape of diameter less than big antelabium.Microcheilia edge 122 has the circumferential protrusion 125 of somewhat larger in diameter in it.The external diameter of little antelabium equals the internal diameter of reservoir.The microcheilia edge is sealed to ventilation insert 117 with the reservoir of breather of the present invention.

Breather 113 has the reservoir 126 that is roughly the hollow cylinder shape, and said reservoir has the top 127 and partially enclosed bottom 128 of opening.Said bottom is level and smooth and along with its descends and becomes circle away from the top.128 the center in the bottom, hole 129 provide the passage that leads to the breather 113 that is connected to the bottom.Said breather then is embodied as the hollow frustoconical, and it is positioned at far-end than major diameter 130 towards reservoir 126 location and minor diameter 131.

Coaxial with breather 113, ventilation insert 117 has far-end insert or internal ventilation pipe 120, and this internal ventilation pipe is positioned at the center of horizontal communication hole 119 mesopores, and perpendicular to the horizontal communication hole 119 relative with insert wall 123.Internal ventilation pipe 120 is a hollow circular cylinder, and its length surpasses its diameter.Internal ventilation pipe 120 and air communication, but can liquid be supplied to the reservoir of breather 113 from horizontal communication hole 119 in the present invention.

Figure 28 illustrates independent breather 113, this breather have with the diameter of the bottom 128 of reservoir 126 near and similarly than major diameter 130.113 of breathers towards minor diameter 131 to the far-end convergent.In the preferred embodiment, approximately be the twice of minor diameter 131 than major diameter 130, promptly the ratio between them is about 2: 1.

Figure 29 illustrates breather 113 once more separately, but it is than major diameter 130 basic diameters less than previous embodiment.In this embodiment, than major diameter 130 than minor diameter 131 greatly 1/8.Breather 131 as aforementioned towards minor diameter 131 to the far-end convergent.In this embodiment, bigger slightly than minor diameter 131 than major diameter 130, the ratio between them is about 1.1: 1.0.

Figure 30 be prior art by chewing the feeding bottle that the baby is using, feeding bottle dropped to and was lower than the baby and prepares the horizontal level below that grips this moment.This feeding bottle 1 has the cylindrical tube of constant diameter.Through downward-sloping feeding bottle, said pipe contacts with nursing liquid.When nipple was pushed rapidly, for example when chewing, the compressed air on the liquid was exerted pressure to the liquid in the container momently.Compressed air sucks and blade through insert from nipple, enters into container subsequently and it is exerted pressure.Air pressurized force liquid rise to having of prior art straight with the breather constant diameter wall.Liquid in the breather enters into suddenly in the insert, and liquid is discharged to outside the feeding bottle through the lateral port of insert herein.The liquid of discharging then leaks on one's body baby or the tender.

The breather of convergent of the present invention shown in Figure 31 disperses to be incorporated into the nursing liquid in the breather.Because the enlarged-diameter of pipe, and since feed liquid flow in the reservoir gradually rather than as prior art unexpected leaking into outside the blow vent, the pipe of given shape, particularly conical pipe are applied to the pressure on the liquid in pipe with dispersion.Feeding bottle 1 among Figure 31 has the taper breather; And its diameter increases from the near-end 130 of narrower far-end 131 to broad; The baby chews nipple 5 and will exert pressure to liquid 2; But the diameter increase of breather has reduced volume gain in the pipe, and has prevented that nursing liquid 2 from discharging and let out from the collar 6 from feeding bottle 1 at insert 119 places.Any pressure that the diameter increase of breather of the present invention has limited in the feeding bottle 1 increases, and has prevented the feeding bottle leakage.

Aforementioned specification has been described the broad edge of ventilation fully or the feeding bottle of other diameter.The unique distinction of said feeding bottle is to reduce the pressure increase in the breather and prevents the leakage of feeding bottle.This feeding bottle and each parts thereof can be by multiple different materials manufacturings, and said material includes but not limited to polymer, low density polyethylene (LDPE), high density polyethylene (HDPE), polypropylene, glass, nylon, iron content and do not conform to iron material, their alloy and complex.
