Description

Drinking container, exhaust system and method

This application requires to enjoy the U.S. Provisional Patent Application NO.60/617 that submitted on October 8th, 2004,375 rights and interests.

Technical field

The present invention relates to a kind of drinking container and by container provide with leakage-preventing and do not have to overflow and to spill the method for the flow of liquid that container uses, leakage-preventing and do not have to overflow and does not spill container such as children's goblet and feeding bottle.

Background technology

The special-purpose feeding bottle of manufacturing is designed to have attempts to reduce zero to the feature near four months infant's eilema symptoms.Especially, US Patent NO.5, in 570.796 and 5,779,071, they be designed to eliminate mixing air and enter baby milk because can increase the risk that produces eilema like this.Simultaneously, owing to be applied in too much " suckings " action, can cause increasing the possibility that children produce sense of hearing infection (ear infection) like this greater than the nipple of four months the required bottle of children.

US Patent NO.5,570.796 and 5,779,071 device that discloses comprises a liquid storage pipe, have the tube portion that is attached to reservoir, like this as a liquid header effect, a plug-in unit is combined to be used on the liquid storage pipe to provide air from the passage of bottle outside to internal circulation.When the bottle in conjunction with those patent characteristics was reversed fully, reservoir (liquid header) comprised liquid storage pipe in-to-in liquid, prevented that liquid from entering the opening of plug-in unit, because the opening of plug-in unit is positioned on the contained fluid level of reservoir.It should be noted that the volume of reservoir volume greater than tube portion, therefore, liquid can all be included in the liquid header under the operating conditions of narrow orifice.Yet bottle can not be filled liquid to the liquid height that is higher than the insert aperture height, and when bottle is reversed, liquid will directly flow to air exhaust port.

On the other hand, because these bottles are discharged fully, when putting upside down fully, liquid will freely flow to liquid outlet, not need children's sucking.If bottle is tilted and will produces the problem that liquid freely overflows and spills like this, even during infant enters deep sleep, liquid also can trickle, and has so just caused that children suffocate.

Further, US Patent NO.5,570.796 and 5,779,071 described device need carefully clean its many required parts and annex.Regrettably, many parts have inner and trickle zone, and cleaning pipe fitting or analogue that this need be out of shape clean.Or even so implement, being difficult to also guarantee that its interior zone is cleaned, most of keepers have no stomach in complexity like this and expensive cleaning way.In addition, be difficult to determine by the sight control interior zone whether it cleans.

And, US Patent NO.5,570.796 and 5,779, in the 071 described device, when bottle is overflowed, also can run into the problem of leakage,, make liquid enter plug-in unit and the final inside that arrives bottle here because described liquid storage pipe and liquid header are filled the volume above liquid header.In addition, the problem that the described device of these patents the time also can occur revealing with regard to extruding when bottle, if the nipple that is connected on the bottle is extruded, if when shaking the bottle with the blended baby milk powder, if liquid is heated when surpassing 45 ℃, if or bottle changed by bar pressure to do the time spent, same, in these cases, liquid also can be flowed out by air outlet passage.

The solution of some problems is described in the PCT of Pyun application WO2004/075810 to some extent like this.This application has been described a kind of feeding bottle, and it has makes extraneous air be introduced in the air intake unit of bottle body, thereby regulates the amount that extraneous air enters bottle.Described air intake unit comprises upper end division board and lower end division board, and an air intake pipe.Division board upper end comprises an air intake slit that is formed by plastics, and the bottom division board covers as one and covers the air intake slit fully, and it is to be fabricated from a silicon and to be equipped with to be used to prevent first test valve of suckling and flowing out round about from air by-pass passage.There is such problem in this structure, and the sealing nipple is exerted pressure down to the institute of air intake unit, and the base plate deformable of silicon materials is so that completely or partially hinder the air intake slit at upper head plate, so has hindered the free-flowing of the air that enters bottle.

The air intake pipe is connected to the bottom surface of lower end division board, and by this way, air admission upper end division board air intake slit is introduced into the body of bottle when outside sucking masterpiece is used the air intake pipe.Second test valve is connected to the air intake pipe, and first test valve allows the air admission bottle, and second dissipates steam or hot air from bottle.Therefore, although described second test valve of the application of Pyun is used to prevent that milk from flowing out from reversing sense, it can not use separately, because allow the rejected heat air on air intake slotted opening direction.In actual applications, the air intake pipe is used to prevent that liquid from passing through second valve and revealing, and is actual as liquid memory use, as top patent is described.Therefore this device does not have the air intake pipe just can not use, because liquid will flow out by the air intake slit.

Summary of the invention

The present invention relates to a kind of beverage device, this device comprises that one is detachably attached to the exhaust system on bottle or the drinking container, described exhaust system comprises a plate-like part, an and body portion, has a check valve on being completed into it on this body portion, exhaust system provides and makes the passage of air from container outer flow feeding internal tank, and valve allows the air admission container, but does not allow liquid through the exhaust system amount discharge container.In these a plurality of embodiments that will introduce body portion, comprise that one has the embodiment of duckbill valve (duck-bill valve).

Can in exhaust system, use a selectable anti-bubbler tube.Anti-bubbler tube makes air admission reversing container arrive the air pocket (air pocket) that forms at container bottom, when using container, is increased on container nozzle or the nipple.This air pocket person of being to use turns by nozzle or nipple, and container produces.By the passage that provides air directly to arrive air pocket, the air of introducing do not allow with container in liquid mixing and in liquid, produce bubble.

Exhaust system can be used to the multiple leakage-preventing and essentially no drinking container that overflows and spill, such as children's goblet, feeding bottle, adult's amusement drinking container, and other drinking container.Will will be appreciated that selectable anti-bubbler tube only is used to feeding bottle, other containers with exhaust system of the present invention also can offer leakage-preventing or not have the container that overflows and spill, or even can not manage.

Exhaust system, anti-bubbler tube and valve play one " diving bell (diving bell) " effect jointly, when being in basic vertical position, drinking container can prevent generally that liquid from entering anti-bubbler tube, this is to be collected into the cause that anti-bubbler tube is opened and just escapes up to valve by air, that is to say, collect air as preventing that liquid from entering the barrier of anti-bubbler tube.The diving bell effect uses container to produce by the user, when the user puts exhaust system (additional have anti-bubbler tube) to container the time.The effect of diving bell makes the user acutely rock container and does not reveal or do not reveal to the vessel filling boiling water.But just complete filling liquid of container like this, that is, container is not filled with can having limitation.

When container reversed and liquid when container is poured out, produce vacuum pressure at internal tank at once, the valve air admission container that is opened.Because air is directed into container, valve discharges " newly " air and enters the collection volume of air to anti-bubbler tube.Should can replace some collection air by " newly " air, therefore compressing is collected air to preventing bubbler tube.In this position, " diving bell " effect is not kept in anti-bubbler tube.Under any circumstance, anti-bubbler tube is finalized and is connected to the exhaust system body portion, only allows small amount of liquid to enter anti-bubbler tube by this way.Therefore, liquid does not cover valve usually.Yet even liquid covers valve, valve prevents that liquid from entering the air inlet passage of exhaust system, although lack the diving bell effect, bottle is still to be operated under the mode of freely revealing.

Selectable anti-bubbler tube is important to neonatal use, because swallow down air the risk that produces big eilema symptom can be arranged.Yet when the baby grew up, this invention also allowed the user to remove anti-bubbler tube and still keeps leakage-preventing exhaust system.

Exhaust system makes the baby inhale drink by nipple or the nozzle that is attached on the bottle at an easy rate from bottle of the present invention, does not increase some vacuum pressures in bottle.Meanwhile, when bottle was reversed or is in obliquity, the valve of exhaust system reduced the possibility that liquid is revealed through exhaust system from bottle, so valve prevents the flow direction exhaust system.Valve is so designed, and having increased when the application force that produces flows out liquid from bottle does not need to apply higher suction, and like this, person capable of reducing using causes the risk of middle ear infection.On the other hand, needs for liquid flow out to be sucked, like this when bottle or container can imitate the chest conveying and prevent that the excessive of liquid from spilling when being reversed.

According to the present invention, small amount of liquid has produced minimum vacuum pressure like this by nipple or nozzle flow container in container when container is reversed or places a certain angle.When children sucked nipple or nozzle, exhaust system can be disposed in the container air environment, and the operation of minimum degree of vacuum is provided.This minimum vacuum pressure produces in container of the present invention and is poured out container guiding air as liquid and enters container up to produce balance between internal tank and atmosphere from air environment.Therefore, container of the present invention need an additional sucking power be accepted the process that liquid can imitate chest to carry like this so that the user provides from container.Yet the vacuum pressure of failing to recognize produces in container owing to discharge in using container processes.

Used in this, " freely revealing " meaning is that container is freely to reveal by exhaust system.Because exhaust system provides exhaust, for prevent by the time the leakage valve be necessary, all embodiment of the present invention implement in the mode of freely revealing.

Used in this, " do not have overflow spills " means by the overflowing of container nipple or nozzle, and certain embodiments of the invention are not implemented there to be the mode of spilling of overflowing.

Exhaust system of the present invention is convenient to clean especially, does not therefore need special cleaning apparatus because body portion and plate-like part do not comprise inner or small ungetable zone.On the contrary, all zones of body portion and plate-like part are to arrive at an easy rate.Therefore, the various assemblies of exhaust system can touch fully to be used for cleaning.In addition, the various assemblies of exhaust system can pass through sight control in cleaning.

Exhaust system of the present invention can append on some available container in the commercial production of nipple.In other embodiments of the invention, exhaust system also can combinedly be used for " suction cup " and the nozzle that children use, and this suction cup also can comprise flexible nozzle.The nothing that device of the present invention can all use with the people of institute's has age is overflow and to be spilt container and use, for example, bicyclist and other sportsmen and motion participant can from use freely reveal basically do not have the excessive container that spills benefited.
