Abstract:
A vent prevents a vacuum within an inverted container of liquid and eliminates components found in other container vents. The vent utilizes a conical or other shaped venting tube extending from the closure or a reservoir with reservoir extension and an air conduit extending inferiorly from a closure. The closure is either a leak resistant or leak proof seal. The superior aspect of the reservoir contains an inferiorly projecting air conduit, opening at the volumetric center of the reservoir. The reservoir extension projects distally into the container to reach the inferior aspect of the container. The vent provides an airway between the outside and the interior of the container so air freely passes to the distal aspect of the container without contaminating the liquid. Any liquid within the reservoir extension then collects in the reservoir during inversion of the container and then returns to the container when upright.

     FIELD OF THE DISCLOSURE 
       [0002]    This disclosure relates to a range of proportions for a vent and a pouring aperture working in combination to fully vent a container in a fashion that is complete, continuous, non-leaking, and without aerating and contaminating the liquid. Additionally, the vent provides a positive pressure in the container to assist in promoting release of the liquid on demand. This disclosure further describes a vent for containers to prevent contamination of liquid in the container. More particularly, this disclosure relates to a vent that prevents the creation of a vacuum inside the container, including containers for liquor, wine, sports drinks, rehydration drinks, water and cola, and other liquids. The disclosure prevents introduction of air into the liquid when poured, thus preventing oxidation and other untoward reactions with the liquid of the container, which alter the taste and quality of the liquid in the container when dispensed. 
       BACKGROUND OF THE DISCLOSURE 
       [0003]    The bottom, or distal, end of containers, particularly liquor, and wine, and other liquid containers is moved upwardly to pour liquid from the bottle, or container, and a vacuum forms during the pour. Air enters the container to fill the vacuum so that more liquid may pour from the container. The air that enters a conventional container in the pouring position is lighter than the liquid in the container and thus, seeks and travels to the most superior portion of the container, that is, its highest point, or its inverted bottom in this pouring position, which is the distal aspect of the container. In traveling to the distal portion of the container, the air contaminates the liquid as it mixes with it, and precipitates chemical reactions within the liquid. Any air that also mixes into the liquid is another untoward outcome of pouring that occurs from prior art containers. 
         [0004]    Many liquids require precise ingredients, and these ingredients are manufactured or grown under strictly controlled conditions. The combining of these ingredients also undergoes close monitoring in a controlled environment, as does the handling of the ingredients and the product in every stage of manufacturing. Also, the handling of the final product has similar tight controls for optimization. Liquors, wines, and other beverages serve as prime examples of the precision and excellence found in a particular industry; The growers of the ingredients of many types of liquor, particularly wine, and the processors of liquors and other liquids, take many precautions to ensure the maximal quality during every step of the production process. But, oxidation of many of the ingredients of wine may occur and diminish the quality of the wine, possibly to the point of consumer rejection. Other unfavorable chemical reactions occur due to the introduction of air into other conventional containers of liquid, such as cola, including the introduction of other airborne chemicals, pollutants, particulates, and the like that may co-contaminate the liquid. Unfortunately, these unfavorable reactions occur repeatedly to the remaining liquid in a conventional container with each pour. The undesirable effects increase many times over as air is frequently reintroduced, with continuing contamination of the liquid. Manufacturers of other liquids have similar and significant need to prevent the contamination of liquids by air. 
       DESCRIPTION OF THE PRIOR ART 
       [0005]    Prior art containers that hold and pour liquids and have disadvantages such as leaking, introducing air into the liquid, not pouring on demand, not venting the container, not providing a positive pressure inside the container, and utilizing more than one component to the vent. Some containers utilize a vent, including liquor bottles and other liquid containers. Frequently, however, such prior art vents require an orientation of the vent, in an upward position, such as U.S. Pat. No. 3,168,221 to Parker. If the vent is not oriented correctly, a significant amount of liquid is spilled from the vent to the outside of the container and typically onto the user of the container. Prior art containers may leak because of container or container component compression in any container direction. Containers may increasingly leak from an increasing amount of pressure on the container or its components and increasing dispenser size. Leaks often take place with the prior art container&#39;s reservoir being in an inverted position. Leaks also appear when the neck size increases. 
         [0006]    One prior art vent terminates at the wall of the reservoir, which requires an orientation of the container to prevent leakage. Another prior art container, when in the dispensing position with a portion of the vent tube directed toward the bottom of the container and submersed in the liquid, introduces air into the liquid and only limited venting takes place, and only after a vacuum has formed. Many prior art containers introduce a multitude of air bubbles into the liquid in the container. Prior art containers also suffer a prolonged lack of venting due to the capillary action of a small vent tube and may trigger a partial vacuum. Further, over tightening of a collar upon an existing container leads to a complete vacuum. Also, prior art containers may trigger the occurrence of negative pressure in the container. Some of the prior art containers utilize a check valve to slow or prevent liquid from leaking from the container, but a negative pressure must form in the container in order for the valve to open, which introduces other negative effects. Prior art containers also prevent the beneficial effect of formation of positive pressure formation in the container. 
         [0007]    During pouring from a prior art container, the path of the liquid stream frequently becomes erratic, thereby making measurement of the liquid dispensed difficult. Prior art containers, especially those of glass, are more difficult to manufacture. Other prior art containers require drilling a hole into the neck of a narrow-neck container as a separate operation. Some other prior art containers attach their reservoirs to the container, utilizing a needle nose pliers, grasping the short vent tube and inserting it into the hole in the neck of the container. Sometimes a ring is attached to the reservoir in order to center the reservoir. However, a reservoir with an attached ring becomes impossible to insert into any size container because the ring centers the reservoir in the center of the neck, preventing insertion of the small vent tube into the neck of the container. If the ring is omitted, the above venting mechanism only has support from the small vent tube in the neck of the container. Tightening the closure too tightly on many prior art containers seals the vent closed, making it inoperable. Further, improper sealing at the closure then may lead to leakage outside the container. A fair number of prior art containers cannot be completely disassembled, which prevents cleaning and results in bacterial buildup and residue, and therefore prevents reuse. Prior art containers also take few steps to prevent the problems associated with air blending with the liquids in the containers. Alas, prior art containers alter the quality of liquid product contained therein as air enters the liquid. Each usage of a prior art container brings in a volume of air that leads to oxidation and other contamination of liquid. Usage and air entrainment lead to the chemical reactions that change the liquid regarding smell, color, taste, and air content among other things. These changes may accumulate and adversely affect the value of the liquid, leading ultimately to its removal from store shelves. 
         [0008]    During pouring from prior art containers, liquid within the venting tube may frequently leak from the container. Liquid also lags and remains in the venting tube, that is, slowly evacuates from the venting tube and returns to the container during inversion and usage of the container. In using prior art containers, the users often do not have the desired rate of pouring of liquid out of the container and also do not have an even rate of pouring of liquid. Prior art containers with vents exhibit a hesitancy of initial liquid flow as the liquid pours from the container upon inversion. Also, the reservoir extension, avoids seeking the distal and lateral aspect of the container, which may lead to contact of the liquid with air, thus degrading the liquid in the container. 
         [0009]    Also, one version of a prior art vent 3168221 to Parker, which is slightly smaller than the pouring spout, is cylindrical and extends from the outside of the container to the bottom of the container, and leaks a significant amount of fluid from the vent when poured, due to the lack of a significant air pressure stream in the vent to propel the liquid in the air vent back into the container before it leaks to the exterior of the container. In another version of the vent to Parker, the vent is much smaller in relation to the liquid pouring spout and liquid either pours slower than desired from the liquid spout or won&#39;t pour at all due to lack of venting relative to the rate of liquid being poured. Also, in the patent to Parker, as well as those to others, the vent doesn&#39;t extend to the bottom of the container, which minimizes the venting of the container, as liquid overlying the exit of the vent prohibits air entry into the vent and container, until a sufficient detrimental vacuum has formed in the container. In all of the versions of the patent to Parker, contamination of the liquid by the air entering the container occurs, and no desirable positive pressure is present in the container at the onset of pouring. 
         [0010]    Some current containers utilize no venting at all into the container and attempt to vent through the drinking aperture of the container while the user is drinking the liquid. If a large aperture at the top of the container is used to drink from, in order to mimic a cup, spilling easily occurs, especially with children and anyone engaging in any type of movement while attempting to drink. 
         [0011]    Some containers have resorted to a smaller aperture in the container, which also introduces multiple disadvantages. The primary disadvantage to that arrangement is that air must enter the container through the liquid as the liquid exits, which aerates the liquid exiting the container as well as the liquid remaining in the container. Aeration has multiple significant disadvantages, as is outlined. Another disadvantage of a small drinking aperture in an unvented container is that a vacuum is present in the container, which slows liquid flow and doesn&#39;t allow for control of removing the liquid. 
       SUMMARY OF THE DISCLOSURE 
       [0012]    Liquid occupies a container, preferably closed at its aperture to prevent spillage, unless opened for pouring. The closure of the container may be of any type, either locating on the interior of the aperture of the container or on the exterior of the container over the aperture. Both closures locations typically provide a spill-resistant or spill-proof closure. 
         [0013]    The first aperture conducts liquid and typically has two ends: proximal and distal. The proximal end typically extends to the superior and lateral surface of the closure and may be of any configuration to assist in pouring the liquid from the container. The distal end of the liquid aperture typically ends at the distal end of the closure. Any portion of this aperture may contain a hollow conduit for optimization of the direction and amount of the fluid flow. A liquid conduit may be inserted into the liquid aperture of the closure at any time during preparation or usage of the container to assist in pouring. A liquid conduit may also come already attached to the closure to assist in pouring. The liquid conduit may be fixed or adjustable in its configuration. The second aperture contains an air aperture vent. 
         [0014]    The preferred embodiment of this disclosure consists of only one additional part, a reservoir and its extension, which is attached to a container and its closure. The disclosure may consist of the reservoir with its extension; the closure and the reservoir with its extension; or, alternatively, the container, the closure, and reservoir with its extension. The reservoir is typically larger than the extension and the extension is typically conical and larger superiorly. An internal venting tube, which is molded as an extension of the closure, has its superior aspect open to the outside ambient air and its inferior aspect open to the volumetric center of the reservoir, thereby providing double venting. The internal venting tube eliminates the need for an additional component for the flow of air, which is unique to this disclosure. Previously, the internal venting tube, which required the attachment of another component for functioning, is now a component of the closure, thereby eliminating the need for attachment of another component for proper functioning. 
         [0015]    In the preferred embodiment, the disclosure operates when liquid is introduced into the container, which then is sealed during manufacturing. Optionally, the container may be filled by the consumer. As the container is inverted and liquid pours from the container though the liquid aperture and any attached liquid conduit, air enters the air conduit. The air then proceeds into the reservoir and its extension and enters the distal aspect of the container, avoiding contact with the liquid in the container. Air, while traversing the reservoir and its preferable conical extension, expels any liquid remaining in the reservoir extension, thereby allowing uninterrupted venting of the container. A small amount of liquid may enter and be contained in the proximal aspect of the reservoir during pouring of the liquid, and this liquid is returned to the container upon resumption of the upright positioning of the container. A volume of air, equal to the volume of liquid removed, is introduced into the superior aspect of the container during pouring of the liquid from the container, to eliminate the vacuum in the container. 
         [0016]    Several embodiments of the current disclosure may be seen. The venting mechanism of the present disclosure includes various shapes. The components of the embodiments may reside in different locations within the disclosure and relative to one another. 
         [0017]    In another embodiment, a venting tube is conically shaped along its entire length. Alternatively, the venting tube may be cylindrical though its length. 
         [0018]    In embodiments of the current disclosure, the venting tube extends from outside the container or closure to the distal, internal aspect of the container, such that it is preferably above the level of the liquid in the container when the container is inverted to empty the liquid from the container. This ensures continuous and full venting of the container without aeration and contamination of the liquid in the container. It also ensures that a positive pressure is present in the container, so that the liquid may be withdrawn from the container on demand, without the interference of vacuum, which is present in traditional containers. Alternatively, the venting tube may be of any size or shape and any reservoir present may be of any size or shape and may contain an optional internal vent tube. Also, any venting tube may contain a flange to retain the venting tube in position and may also contain an internal flange to retain liquid and prevent leakage. Leakage is also prevented due to the diameters of the vent and pouring apertures. The range of proportions of internal diameters of the venting tube to the pouring aperture, approximately 1:2.5 (venting tube internal diameter: liquid aperture) allows for rapid and simultaneous reentry of the liquid inside the venting tube into the container followed by air entry above the level of liquid when the container is inverted. 
         [0019]    Thus, for the first time, utilizing a one piece—venting mechanism, continuous and full venting, without leaking, without aerating, and without contaminating the liquid in the container takes place, while providing a positive pressure in the container, for removal of liquid on demand without the interference of vacuum, as seen in traditional containers. An additional embodiment shows a flange at the superior aspect of the venting tube to retain the tube in position and a thickening of the internal wall of the superior wall of the vent, which may help retain fluid within the venting tube during unusual situations. Preferably the vent tube has a generally conical shape throughout its entire length. In other embodiments, a conical shape may extend for a variable distance of the tube and it may have a distinct shape at and for any portion of its length, and may be attached in any fashion, either directly or indirectly, to the closure, dispenser, or body of the container. 
         [0020]    Alternatively, the container vent locates superiorly to the closure or in another position on the container or associated parts and includes a double-venting reservoir with an associated reservoir extension projecting inferiorly from the inferior aspect of the reservoir to approximate the inferior and lateral edge of the container. The vent may be variably shaped. An air conduit extends distally from the superior aspect of the reservoir preferably into the volumetric center of the reservoir and is in contact with the ambient air outside the liquid container. The reservoir is larger in diameter than its extension. The reservoir and its extension may consist of one or more pieces. The reservoir extension projects to the inferior aspect of the container, and may be attached to the reservoir with a press fit and may be of any length to adjust to the size of the container. The reservoir and its extension may be of any size and shape. Preferably, the extension of the reservoir is not linear to the air conduit of the reservoir. This prevents any liquid that may enter the reservoir during usage from access to the air conduit in the superior aspect of the reservoir. The reservoir and its accompanying superiorly located air conduit and inferiorly located extension are attached or preassembled to the closure or other aspects of the container or associated parts. 
         [0021]    Both the extension of the reservoir and the venting tube embodiments may be preferably composed of a buoyant material or a material that is shaped to seek the superior aspect of the container while in the inverted position, which is accomplished by them floating, by their shapes leading to the airspace, or any other means of positioning themselves to reside in the airspace of the container during usage, to minimize any contact of the liquid with air. Different combinations of these components would be preferable in certain containers. 
         [0022]    In another embodiment, the second aperture communicates with the venting tube, with the tube approximating the aperture and extending into the container, preferable to the inferior aspect of the container, and preferably superior to the liquid of the container when the container is inverted. 
         [0023]    Alternatively, the second aperture of the closure approximates the reservoir with its air conduit and the extension of the reservoir and extends through the length of the container from the proximal to the distal ends. The reservoir may have a position on the superior aspect of the closure, but may have a position in any location, including the interior of the container. Any ends of the apertures and conduits may contain caps. The reservoir and its extension, as well as a venting tube, may be packaged individually or together to be used with a closure, container, air and/or fluid conduits, or any combination thereof. 
         [0024]    In the venting tube embodiment of the disclosure, while in the upright position, has liquid in the venting tube, and when the container is inverted during usage, the inwardly moving air expediently evacuates this liquid into the interior of the container and conducts the air concurrently to the superior aspect of the inverted container, while ensuring no contamination of the liquid in the container with air. In this embodiment, the venting tube, with its preferred conical shape, ensures that the liquid within it, while in the upright position, remains in the tube. Also, the tube assures that during usage, liquid does not exit the container because the liquid is rapidly evacuated from the conically or otherwise shaped venting tube back into the container during inversion and usage of the container. This is accomplished by air quickly entering the tube to vent the container during usage. Both the volume of air in the superior aspect of the conically or otherwise shaped tube and the differential amounts of air in the two ends of the conically or otherwise shaped venting tube along with the approximate ratio of the venting tube to pouring aperture contribute to the unique ability of the venting tube to quickly evacuate the liquid within the tube. The venting tube resting in the airspace of the container during inversion and usage also contributes to venting, as the liquid in the venting tube doesn&#39;t have to displace any liquid overlying the venting tube in order to enter the container. 
         [0025]    Also, in one embodiment, the superior aspect of the conical or other shape of the venting tube assists in holding any remaining liquid in the venting tube when the container is inverted for usage. This may be done by any reservoir or material in the internal portion of superior aspect of the venting tube. In addition, the vent ensures that the desired rate of pouring of liquid to the exterior of the container is obtained, that an even rate of pouring of liquid out of the container is obtained, that the liquid comes out the container upon inversion of the container during usage without hesitancy, and that there is no initial large egress of liquid from the container with initial inversion of the container. Another embodiment consists of the conical or otherwise shaped vent located on the interior of the container, contoured to the container, closure, or liquid dispenser, ending in the inferior aspect of the container, such that air is channeled to the inferior aspect of the container. Another embodiment shows a check valve in one or more portions in order to prevent the flow of liquid out of the vent, and subsequently the container, while the vent allows for the entry of air into the container as liquid is removed from the container. Also, the disclosure and its embodiments preferably seek the superior aspect of the container during usage to minimize any contact of the liquid with air. Flanges may be present in any configuration externally to assist with tube positioning and internally to assist in prevention of leakage of fluid from the container in certain embodiments. In addition, all surfaces of the disclosure may consist of various textures, various degrees of smoothness, and various shapes in order to enhance the return of liquid to interior of the container during usage.

       DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0126]    The present disclosure overcomes the prior art by providing a venting tube enabling return of any liquid in the venting tube back into the container without leakage out of the container. The present disclosure provides a vent to overcome the disadvantages of the prior art by providing a liquid aperture, an air aperture, and a venting mechanism of various shapes and proportions to simultaneously vent a container and prevent leakage from the container while utilizing a preferably conical mechanism and utilizing only one additional part to the container and closure. Additionally, double venting and a reservoir are utilized. 
         [0127]    Another embodiment of the present disclosure overcomes the prior art limitations by providing a closure, venting, and related components that fit on or within the neck of a liquid container, such as a wine bottle, sports bottle, or other container, and minimizes the mixing of air with liquid not yet poured from the container while eliminating spillage from the container during pouring. 
         [0128]    Another embodiment utilizes a vent tube. The vent tube extends from the exterior of the container to the interior inferior aspect of the container. 
         [0129]      FIG. 1  illustrates a liquid container B, which is illustrative of the prior art, with liquid L placed therein. The liquid has a surface S denoting the top of the liquid, above which any air in the container collects. The container B has a narrow neck N generally centered upon the container and extending outwardly from the main portion of the container. The container has a closure as at C upon the neck that retains the liquid within the container following manufacture and keeps air out of the container prior to opening. 
         [0130]    To consume the liquid in a prior art container, a user removes the closure C and then grasps the container. During usage of a container B, that is, pouring, a user tips the container and orients the container with the neck N generally downward as shown in  FIG. 2 . With the neck downward, the bottom of the container B is generally upward which moves the liquid L towards the neck and the surface S in the direction of the bottom. As the liquid exits the neck into a glass G, air enters the neck N and travels through the liquid L and breaks the surface S to locate above the liquid. As described above, air passing through the liquid in most of the prior art introduces various reactants and pollutants into the liquid, which is particularly detrimental in those individuals who are rehydrating and consuming large amounts of liquids. This affects most particularly those in sports that are intense and require optimal heart rate control, as air introduction into the stomach, which causes stomach distension, disrupts the body&#39;s automatic heart rate adjustments that are necessary for optimum performance. Also, those with a discriminating palate can detect alterations to the liquid brought on by the passage of air through the liquid. 
         [0131]      FIG. 3 , the preferred embodiment, a closure  5  is noted. The closure allows for passage of both air and fluid through appropriate passages without fluid entering the air passage and vice versa. If mixing of air and liquid do occur, as they do in the prior art, leaks and ingestion of air during intake occur. The closure  5  turns upon the neck in a threaded connection to the container. The closure  5  has a perimeter flange  12  with internal threads that engage the threads of the neck. The closure has its surface  2 , visible to the user, generally perpendicular to the perimeter flange. The surface has a spout  4  formed therein for passage of fluids from the container to a user. The spout is here shown as a round cylinder as seen by a user. Spaced away from the spout, generally centered in the closure, the closure has its aperture  15  for venting of the container during usage, that is, the passage of air. Generally, all embodiments of the disclosure preferably have the venting mechanism located in the center of the closure. In this embodiment, the aperture represents the exterior opening of an internal venting tube  8 . The internal venting tube  8  approximates the surface  2  and passes through the closure  5 . The internal venting tube  8  generally has a constant diameter and hollow construction for passage of air there through. Opposite the spout  4 , the closure has an accepting flange  7  that extends inferiorly from the closure. The accepting flange is generally round, though here shown as two spaced apart walls in a section view. The accepting flange has a frusto-conical interior shape with a curved recess  17  approximately half way along the depth of the accepting flange. The curved recess defines a plane generally parallel to the surface  2  and extends around the internal circumference of the accepting flange. 
         [0132]    The accepting flange receives a reservoir  6 , generally a hollow cylinder with an open top  19  and a partially closed bottom  20 . The bottom has an aperture  21  from which extend a conically shaped reservoir extension  18 . The reservoir in combination with the reservoir extension  18  extends the vent to proximate the bottom of a container. The reservoir has its top slightly beveled inwardly as at  19   a  where the bevel generally matches the interior frusto-conical shape of the accepting flange. The reservoir superior side wall also includes at least one detent  19   b  here shown as two protrusions outwardly from the beveled portion of the top as at  19   a . The detents can have the form of separate spaced apart protrusions. Preferably, the detents form a ring upon the perimeter of the superior side wall so that the detent fits into the recess  17  of the accepting flange. Alternatively, the reservoir may attach by friction fit or any other attachment to the accepting flange. The detent and the recess cooperate to secure the reservoir to the accepting flange of the closure. The internal venting tube  8  extends into the reservoir when secured to the accepting flange. The internal venting tube generally opens at the volumetric center of the reservoir so that the internal venting tube allows passage of air regardless of the angle of the reservoir, that is, the internal venting tube remains above the surface of any liquid within the reservoir. 
         [0133]      FIG. 3A  shows an alternate embodiment of the closure  5  where it has an internal venting tube  8  having a aperture  15  on the surface  2 . Offset from the aperture, the closure may have a truncated spout  4  having a height above the surface opposite the internal venting tube of approximately the thickness of the closure or consist of any other type of aperture. The closure has an aperture to receive a typical spout, nipple or other aperture  23  typically having a flat flange  23   a  from which extends a spout, nipple or other aperture  23   b . Alternatively, the spout or other form of drinking aperture may come attached to the closure or otherwise be associated with the closure. When installed as shown, the  3  nipple passes its elongated spherical tip through the spout or other aperture  4  and away from the closure. The flat flange of the nipple then abuts the closure opposite the surface  2 . The closure has sufficient diameter to provide for the internal venting tube and the accepting flange  7  and the diameter of the flat flange  23   a  of the spout, nipple or other aperture. 
         [0134]    Then  FIG. 3B  shows another alternate embodiment of the closure  5  with a generally flat surface  2  and a depending perimeter flange  12  as previously described, where it has an internal venting tube  8  having a flush aperture  15  with the surface  2 . Centered upon the surface of the closure, this alternate embodiment has a shortened spout or other aperture  4  which may have a height above the surface. The closure has an aperture to receive a typical spout, nipple or other aperture  23  having a flat flange  23   a  from which extends a spout, nipple or other aperture, and which may consist of an elongated spherical tip  23   b  as known in the art. When installed as shown, the nipple passes its elongated spherical tip through the spout  4  and away from the closure. The flat flange of the nipple then abuts the closure opposite the surface  2 . The closure has sufficient diameter to provide for the internal venting tube and the accepting flange  7  and the diameter of the flat flange  23   a  of the nipple. The accepting flange is generally round and concentric with the internal vent tube. The accepting flange  7  has the recesses  17  partially along its length that receive the detents  19   b  from the reservoir as shown. 
         [0135]      FIG. 4  shows, as above, the reservoir  6  fits its top  19  into the accepting flange  7  with the internal venting tube  8  extending into the volumetric center of the reservoir. The top of the reservoir secures to the accepting flange as the detent  19   b  engages the recess  17 . Offset from the aperture  15 , this embodiment of the closure has its spout  4  typically of greater diameter than the internal venting tube  8 . The spout extends generally perpendicular to the surface  2  of the closure with the majority of the spout outwardly from the surface. The spout also extends generally parallel to the internal venting tube  8  and within the perimeter flange  12 . The spout has two opposite ends, one end opening to the atmosphere away from the closure and another end locating into the closure. The other end of the spout includes an optional check valve  22 . The check valve allows passage of liquids outwardly from the closure but prevents introduction of liquids and gases through the spout and the check valve into the container. Typically, the check valve forms integrally with the closure. In an alternate embodiment, the check valve is a separate component attached to the closure during manufacturing. 
         [0136]      FIG. 5  shows the side view of the liquid container and demonstrates the preferably conical venting tube extending from the top of the container to the inferior aspect of the container. Here, the closure  5  secures upon a neck N of the container, here shown as a bottle, though other containers are foreseen. The neck extends upwardly from an end, generally the top, of the bottle. The neck has external threads that engage internal threads  11  upon the interior of a perimeter flange  12  of the closure. The flange extends around the perimeter of the closure generally perpendicular to a surface  2  of the closure through which pass the vent  1  and the spout  4 . In this view, the vent passes flush through the closure, as at  13 , and enters the container. The vent is generally elongated, hollow, and tapered as it extends beyond the closure inferiorly to proximate the bottom, as at B′, of the bottle. The vent typically tapers at least ½ of 1% from the closure towards its tip, as at  14 , but may taper any amount. The tip also has a slight bevel, that is, angled cut to prevent clogging proximate the bottom. Further, the closure  5  has the spout  4  extending upwardly from the surface  2  or opposite the neck N. In this embodiment, the spout remains integral with the closure while alternatively the spout may be a separate piece inserted into the closure. As in  FIG. 1 , the spout preferably has an area, here represented by its internal diameter, approximately 2.5 times that of the vent. Generally, when a reservoir is not present, the preferred ratio of the fluid aperture to the venting aperture is 2.5:1 in various embodiments of the disclosure. 
         [0137]    Another embodiment, demonstrated in  FIG. 6 , shows the top aspect of the liquid container and demonstrates one proportion in the range of proportions of the internal diameters of the pouring aperture and the superior aspect of the preferably conical venting tube. This figure shows the top of a closure for a container B, a vent  1  in the closure  5 , and a spout  4  proximate the vent that minimizes the mixing of air with liquid not yet poured from the container. The vent and spout have a proportional relationship generally where the diameter of the spout is generally 2.5 times that of the diameter of the vent. Here the vent and the spout are shown being round so the proportion of the area is reflected in their diameters. Though a round vent and a round spout are shown, the Applicants foresee alternate shapes for the openings provided the ratio of areas remains similar.  FIG. 6  generally shows the proportions of the internal diameters of the spout  4  and the superior aspect of the vent  1 . Though a closure  5  is shown, the Applicants foresee that the vent and the spout of the disclosure can be inserted directly into a completely closed top of a container and function similarly provided the proportions of the disclosure are maintained. 
         [0138]      FIG. 7  shows the side view of the liquid container and demonstrates the preferably conical venting tube extending from the top to the bottom of the container. Also demonstrated are optional flanges  9 ,  10 . Optional flange  9  is external to the diameter of the venting tube and may help maintain the position of the venting tube. Optional flange  10  is internal to the venting tube and may help with retention of any fluid in the venting tube while the container is in use. In an alternate embodiment of the disclosure,  FIG. 7  shows the container B as a bottle as in  FIG. 5  with a closure  5  upon the neck N. The closure has an integral spout  4  as before. The closure though has an aperture  15  in the surface  2 . The aperture allows venting of the container in combination with the spout as is commonly known. This alternate embodiment though provides a vent  1  placed through the aperture generally tapered as before but with a stop flange  9  upon one end of the vent with the other end of the vent having a beveled cut, as at  14 , as previously described. The stop flange extends around the perimeter of the vent and outwardly from the vent. The stop flange prevents the vent from falling through the aperture and into the bottle. Further, the stop flange continues inwardly as a retainer flange  10  that partially closes the vent. The retainer flange holds residual fluid in the vent when the container is inverted during usage. 
         [0139]      FIG. 8  shows the side view of the liquid container and demonstrates the cylindrical venting tube extending from the top of the container to the inferior aspect of the container.  FIG. 8  then shows the closure  5  secured upon a neck N of the bottle but with an alternate embodiment of the vent. As before, the neck extends upwardly from the top of the bottle. The neck has external threads that engage internal threads  11  upon the interior of a perimeter flange  12  of the closure. The flange extends around the perimeter of the closure, perpendicular to the surface  2  of the closure through which pass an alternate embodiment of the vent as at  16  and the spout  4 . In this view, the vent passes flush through the closure, as at  13 , and enters the container. The vent is generally an elongated, hollow cylinder of constant diameter that extends beyond the closure inferiorly to proximate the bottom, as at B′, of the container. The alternate embodiment of the vent  16  has its tip  14 , also with a slight bevel for clog prevention typically close to the bottom. As before, the spout  4  extends upwardly from the surface  2  or opposite the neck N for ease of use. In this embodiment, the spout remains integral with the closure but may also be provided as a separate piece for insertion during manufacturing or by the end user through the closure. All embodiments may utilize a spout integral to the closure, or may attach any spout to the closure. As in  FIG. 6 , the spout has an area, here represented by its internal diameter, approximately 2.5 times that of the vent. 
         [0140]      FIG. 9  shows the top aspect of the liquid container and demonstrates one proportion in the range of proportions of the internal diameters of the pouring aperture and the superior aspect of the cylindrical venting tube. This figure shows the top of a closure for a container C, a vent  1  in the closure  5 , and a spout  4  along with the vent, that minimizes the mixing of air with liquid not yet poured from the container. The vent and spout have a proportional relationship generally where the area of the spout is approximately 2.5 times that of the area of the vent. Here the vent and the spout are shown being round so the proportion of the area is reflected in their diameters. Though a round vent and a round spout are shown, the Applicants foresee alternate shapes for the openings provided the ratio of areas remains similar.  FIG. 9  generally shows the proportions of the internal diameters of the spout  4  and the superior aspect of the vent  1 . Though a closure  5  is shown, the Applicants foresee that the vent and the spout of the disclosure can be inserted directly into a completely closed top of a container and function similarly provided the proportions of the disclosure are maintained. 
         [0141]      FIG. 10  shows the side view of the liquid container and demonstrates a cylindrical vent tube extending from the top to the bottom of the container. Also demonstrated are optional flanges  9 ,  10 . Optional flange  9  is external to the diameter of the venting tube and may help maintain the position of the venting tube. Optional flange  10  is internal to the venting tube and may help with retention of any fluid in the venting tube while the container is in use. Here this figure shows the container B as a bottle with a closure  5  upon the neck N. The closure has its integral spout  4  and its aperture  15  in the surface  2 . This alternate embodiment though provides the vent  16  placed through the aperture generally cylindrical as before but with a stop flange  9  upon one end of the vent with the other end of the vent having a beveled cut, as at  14 , as previously described. The stop flange extends around the perimeter of the vent and outwardly from the vent, generally having a greater diameter than the diameter of the aperture  15 . The stop flange prevents the vent from falling through the closure and into the bottle. Further, the stop flange continues inwardly as a retainer flange  10  that partially closes the vent, similar to  FIG. 7 . 
         [0142]      FIG. 11  demonstrates an alternate embodiment of the disclosure where the container B has a generally narrow neck N. The neck has a closure  5  threadedly engaged to the neck. The closure has its surface  2  as before that has an aperture  24  that vents air into the container and a nearby aperture  25  that passes fluid. This embodiment has a short section of tube utilized as an optional fluid conduit  26  placed through the fluid aperture  25 . The closure also admits an external venting tube  27  through the aperture  24 . The venting tube is generally elongated and narrow as it extends from the closure into the neck of the container. The venting tube merges with a conical or otherwise shaped ( FIG. 11A ) reservoir  6 , generally at the proximal or wide end, of the reservoir. Distal to the reservoir, extension  18  extends proximate to the distal end of the container. The reservoir extension typically has a length greater than the reservoir and a generally conical shape with a beveled opening proximate the bottom B′ of the container.  FIG. 11A  shows a similar embodiment to  FIG. 11 , and demonstrates a cylindrical rather than conical reservoir  6 . 
         [0143]      FIG. 12  demonstrates another alternate embodiment of the disclosure with a narrow neck N upon a container B. The neck has a closure  5  threadedly engaged to it. The neck extends upwardly from an end, generally the top, of the container. The neck has external threads that engage internal threads  11  upon the interior of a perimeter flange  12  of the closure. The flange extends around the perimeter of the closure generally perpendicular to a surface  2  of the closure through which pass the internal vent  28  and the optional fluid conduit  26 . The closure has its surface  2  with the air aperture  24  and a nearby aperture  25  that passes fluid. This embodiment has a short section of tube utilized as an optional fluid conduit  26  placed through the fluid aperture  25 . The closure also admits a shortened internal venting tube as at  28  through the aperture  24 . The air conduit  28  maintains communication with ambient air outside the container B. The air aperture  24  passes the ambient air into the venting tube  1 . In this view, the air conduit  28  passes through the closure and enters the container. The vent, as at  1 , is generally elongated, hollow, and tapered as it extends beyond the closure inferiorly to proximate the bottom, as at B′, of the bottle. The vent typically tapers at least ½ of 1% from the closure towards its tip, as at  14 . The tip also has a slight bevel, that is, angled cut to prevent clogging proximate the bottom. In this embodiment, the air conduit and optional fluid conduit  26  may both be integral to the closure or may be separate pieces. As before, the aperture  25  for liquid passage has an diameter approximately 2.5 times that of the aperture  24  for venting air. 
         [0144]      FIG. 13  shows a similar container B with a closure  5  having an aperture  25  for passing liquid through an optional fluid conduit  26  and venting air through an aperture  15  in the surface  2  of the closure. The aperture  15  allows for venting of air through closure  12  but without an air conduit, thus eliminating one part. This figure shows an optional liquid conduit  26  extending into the container. The vent, as at  1 , is generally elongated, hollow, and tapered as it extends beneath the closure inferiorly to proximate the bottom, as at B′, of the bottle. The vent typically tapers at least ½ of 1% from the closure towards its tip, as at  14 . The tip also has an angled cut to prevent clogging proximate the bottom. As before, the aperture  25  for liquid passage has an area approximately 2.5 times that of the aperture  15  for venting air. 
         [0145]      FIG. 14  shows another embodiment of the current disclosure where the internal venting tube is preferably conical in a distal portion of its length, as at  29 , and inserted into the container B. It may be inserted into any aspect of the container or closure. This version of the current disclosure has an additional advantage in that a current container need only be modified by providing a liquid aperture, an aperture on the surface of container, cap, plug, or similar device, and associating a preferably conical vent to the air aperture. Many parts, costs, assemblies, leaks, time to assemble, and other disadvantages of the prior art vanish when utilizing this version. This figure shows the side view of the liquid container B and demonstrates the conically shaped internal venting tube  29  extending from the surface  2  of the closure to the inferior aspect of the container. As before, the closure  5  secured upon a neck N of the container using threads, internal threads  11  upon the interior of a perimeter flange  12  of the closure. The flange extends around the perimeter of the closure, perpendicular to the surface  2  of the closure through which connects the venting tube as at  15  and the spout  4  shown as a short section of tube extending above and beneath the surface of the closure. In this view, the vent passes through the closure and enters the container. The external venting tube is generally an elongated, hollow cone of various diameters that extends beyond the closure inferiorly to approximate the bottom, as at B′, of the container. This embodiment of the vent  29  has its tip  14 , also with a slight bevel for clog prevention so close to the bottom. In this embodiment, the spout remains integral with the closure but may also be provided as a separate piece for insertion during manufacturing or by the end user through the closure. As in  FIG. 5 , the spout has an area, here represented by its internal diameter, approximately 2.5 times that of the vent. 
         [0146]      FIG. 14A  demonstrates the addition of an optional stop flange  9  to the superior aspect of the internal venting tube  29 . The stop flange extends outwardly from the aperture  15  and prevents the tube  29  from slipping into the container when as a separate piece from the closure. Any of the venting tubes or other portions of any versions may be cleaned and reused or may be disposable. 
         [0147]    In  FIG. 15 , the preferably conical vent is situated such that the superior aspect vents as at  15  from the closure  5  and contains a preferably conical aspect in the proximal region as at  30  with a cylindrical vent extension  31  depending from the conical aspect. The vent extension has a length that allows for its opening as at  14  proximate the bottom B′ of the container. The preferably conical aspect may be in any location of the container or closure, as shown in  FIGS. 16 ,  17 ,  18 , or any proportion or aspect of the tube as later shown in  FIG. 19 .  FIG. 16  shows the proximal region  30  opening as at  15  in the threaded region of the neck.  FIG. 17  provides an opening  15  beneath the neck N where the proximal region  30  opens and has a stop flange  9  upon its perimeter. The proximal region extends downwardly and inwardly into the container B with the reservoir extension  31  further extending towards a corner of the bottom B′.  FIG. 18  next provides the opening  15  of the vent well below the neck N and generally in a wall W. As before, the proximal region  30  of the conical vent opens and utilizes its stop flange  9  to prevent the vent from falling into the container B. The proximal region extends downwardly and inwardly into the container B with the reservoir extension  31  further extending preferably into the airspace of B′. 
         [0148]      FIG. 19  then shows the proximal vent  27  opening as at  15  in the threaded region of the neck. This alternate embodiment of the disclosure has the closure  5  threadily engaged to the neck. The closure has its surface  2  as before that has an aperture  25  that passes fluid but not an aperture that vents air as in previous embodiments. This embodiment has a short section of tube utilized as an optional fluid conduit  26  placed through the fluid aperture  25 . The neck N of the container admits an external venting tube  27  that opens as at  15 . The external venting tube is generally elongated, narrow and curved as it extends from proximate the closure and into the neck of the container. The external venting tube merges with a conically shaped reservoir  6 , generally at its wide end as shown. Opposite the external venting tube, the reservoir narrows in diameter to the reservoir extension  18  which typically have a length greater than the reservoir. The generally cylindrical reservoir extension has a beveled opening  14  proximate the bottom B′ of the container. Any combination of the previously described arrangements of closure  5 , opening  15 , neck N, and the various venting tubes with and without reservoirs meet the performance characteristics of the disclosure.  FIG. 20  further shows the combination of the closure  5  upon a threaded neck N where the external venting tube  27  opens below the threaded portion of the neck. The external venting tube then continues downwardly into the wide end of the reservoir  6  and its depending reservoir extension  18  as shown. And,  FIG. 21  has a container B with a neck N closed by the closure  5 . This embodiment though has the opening  15  in the wall W of the container. The opening admits the external venting tube  27  for venting air from the atmosphere to the container. The external venting tube then continues to the wide end of the reservoir  6  which then continues to the reservoir extension  18  as shown. In the various embodiments previously shown and described, an optional flange as at  9  and optional internal proximal thickening as at  10  may be present, also in any configuration. 
         [0149]      FIG. 22  shows a plug  2 , or closure. The plug has a generally round shape to accommodate the shape of a round neck. However, the plug may have an alternate shape to accommodate necks or container openings of other shapes. The venting aperture and pouring aperture are generally located upon a diametrical line across the plug in this embodiment. Alternatively, the venting aperture may have a location spaced away from the pouring aperture so long as air can entered the vent tube. 
         [0150]      FIG. 23  then shows a section view of one embodiment of an embodiment of the present disclosure removed from a container B. The disclosure, shown in top view in  FIG. 22 , has a plug  40 , generally round, to fit the neck N of a container. The plug is generally an elongated cylinder with at least three flanges  40   a , generally mutually parallel and extending outwardly from the cylinder. The flanges have an outside diameter generally that of the inside diameter of the neck. Opposite the flanges and upon one end, the plug has its top  40   b  that has a diameter at least slightly more than the inside diameter of the neck. Preferably the top has a diameter that exceeds the outside diameter of the neck. The plug has two parallel lengthwise apertures that receive the liquid conduit  41 , and the air conduit  42 . 
         [0151]    The liquid tube  41 , which is in contact with the liquid aperture  25 , has a cap  41   a  outwardly from the plug which a user can remove to begin the flow of liquid from within the container. The vent tube also has its cap  42   a  that fits upon the vent tube also outwardly from the plug. A user can remove the cap  42   a  from the vent tube to begin the flow of air into the container to eliminate the vacuum beyond the surface of the liquid therein. Preferably, the caps  41   a ,  42   a  have a common tether  42   b  secured to the plug that prevents inadvertent loss. The internal venting tube  42  has a generally elongated hollow cylindrical form. The internal venting tube  42 , or air conduit, preferably extends from slightly above the top  40   b  of the plug, through the plug, and well below the plug as at  42   c . Away from the plug, opposite the top, the vent tube, as at  42   c , has a slight bulge outwardly as at  43 . Preferably the bulge has a rounded outer surface and a diameter slightly more than the outside diameter of the vent tube. Beneath the bulge  43 , the vent tube continues at its outside diameter and hollow construction, as at  42   d.    
         [0152]    The bulge  43  of the vent tube  42  receives a stem  48   a  of a reservoir plug  48 . The stem  48   a  is a generally hollow, elongated cylinder with an inside diameter slightly larger than the outside diameter of the vent tube. The stem has sufficient length to slide over the bulge  43  in the vent tube  42  thus securing the reservoir plug  48  to the vent tube. The reservoir plug is generally cylindrical. In one embodiment, the reservoir plug has a flange  48   b  with a slightly larger diameter than the remainder of the reservoir plug. The reservoir plug has an aperture there through that admits the vent tube. The reservoir plug has a generally solid construction outside of the aperture to prevent migration of fluids and gases through the reservoir plug. The stem  48   a  is generally an integral part of the reservoir plug  48  and centered thereon. 
         [0153]    The reservoir plug  48  receives the reservoir  6  inwardly of the flange  48   b . The reservoir is generally hollow and cylindrical in shape. The reservoir has an open superior end as at  47  and an opposite partially hemispherical inferior end as at  20 . The inferior end has an aperture therein  21  that open to a reservoir extension  18  that narrows to a tip as at  14 . In this embodiment, a flexible air conduit or hollow tubing  46  extends from the reservoir  6  to the surface of liquid within a container B when the container is in the inverted position. The free end  49  of the tubing generally approximates the bottom of the container or follows the surface of the liquid when inverted while its opposite fixed end as at  50  fits upon the outside surface of the tip  14 . The tubing may have buoyancy and sufficient length to exceed the height of the container B and to avoid kinking of the tubing. It may also approximate the air space of the container B while in the inverted position. Air is free to enter the container through the air aperture  24 , which typically contains an air tube  42 , into the reservoir and then into the reservoir extension, above the surface of the liquid remaining in the container B when inverted. The reservoir has sufficient volume to contain liquid from the reservoir extension when the container is inverted. 
         [0154]      FIG. 24  shows a similar venting tube to  FIG. 11 , with the exception of a stopper or plug  40  utilized to seal the container B, rather than the cap like closure  5  seen in  FIG. 11 .  FIG. 24  demonstrates an alternate embodiment of the disclosure where the container B has a generally narrow neck N. The neck has a plug  40  inserted within the narrow neck. The plug has its surface  2  as before that has an aperture  24  that vents air into the container and a nearby aperture  25  that passes fluid. This embodiment has a short section of tube utilized as an optional fluid conduit  41  placed through the fluid aperture  25 . The liquid conduit is generally elongated and narrow as it extends from above the plug, though the plug, and preferably flushes with the bottom of the plug. The air aperture  24  admits an internal venting tube  42  that extends from slightly above the surface, through the plug, and into the container. The internal venting tube  42  extends into the container as at  42   c . This portion of the internal venting tube bulges outward slightly as described in  FIG. 23 . Over the bulges, the internal venting tube receives a grooved section, as at  6   a , extending above the reservoir  6 . The grooved section extends outwardly from the wide end of the reservoir as shown. Opposite the grooved section, the reservoir narrows in diameter to a reservoir extension  18 . The reservoir extension typically has a length greater than the reservoir and a generally conical shape, but may be any shape, with a beveled opening proximate the bottom B′ of the container. 
         [0155]      FIG. 25  shows similar construction and assembly of this alternate embodiment as in  FIG. 24 . However, the reservoir  6  has a greater length than in  FIG. 24 , and generally exceeds the length of the reservoir extension  18 . The reservoir extends the preferably conical aspect of itself over a longer aspect of the vent of this embodiment. 
         [0156]      FIG. 26  shows similar construction and assembly as  FIGS. 24 and 25 , but the reservoir  6  again increases its length in proportion to the reservoir extension  18 . The reservoir has a length of at least twice that of the reservoir extension. The reservoir retains its generally conical shape for its length, narrowing from a wide end proximate the internal venting tube to its merge with the reservoir extension.  FIG. 27  then shows a reservoir  6  having a generally conical shape but without a reservoir extension as shown in  FIGS. 24-26 . The reservoir has a wide end proximate the internal venting tube  42   c  and the reservoir then tapers to its beveled opening as at  14 . 
         [0157]    Building on the top view in  FIG. 22 ,  FIG. 28  shows an embodiment of the present disclosure employed in a container B to eliminate the blending of air in the liquid as shown in  FIG. 2 . This embodiment has its plug  40  installed in the neck N of an inverted container B. The container B has a quantity of liquid therein with a surface S locating away from the neck and towards the bottom of the container B. The plug has a pouring aperture and liquid conduit  41  extending through its length and into the neck. Generally parallel and near the liquid conduit  41 , the venting aperture and air conduit  42  extends through the plug and into the vent. The internal vent tube, which is in contact with the venting aperture, bulges slightly, as at  43 , for securement of a reservoir  6 . The reservoir has a generally elongated cylindrical form rounded upon its inferior end as at  20 . The inferior end of the reservoir provides a connection for a section of the preferably conical tubing  46 . The tubing may have inherent buoyancy, that is, a density less than the liquid, may elongate, and then may float upon the surface S. The tubing opens at the surface, as at its free end  49 , either through buoyancy or through its direction, and allows introduction of air above the surface but not through the liquid remaining in the container B. 
         [0158]      FIG. 29  demonstrates an alternate embodiment of the disclosure that has a venting mechanism as previously shown in  FIG. 24 . This venting mechanism has a preferably conically reservoir  6  with a grooved section  6   a  extending above the wide end of the reservoir towards the plug  40 . The grooved section slips over the internal venting tube as at  6   a . Opposite the grooved section, the reservoir tapers and connects at its distal aspect to the end  50  of a flexible vent extension  46 , or tube. The free end  49  of the flexible reservoir extension can move within the container. The flexible vent extension typically has a length at least twice that of the reservoir as shown. 
         [0159]    Slightly different than  FIG. 29 ,  FIG. 30  has a reservoir  6  in communication with the internal venting tube  42  through an enlarged section  6   a . The reservoir, similar to  FIG. 25 , has a wide end from which the grooved section extends and a taper over its length. The reservoir in  FIG. 30  has a greater length than in  FIG. 29 , approximately the same length as the flexible vent extension  46 . As before, the end  50  connects to the narrow tip of the conical reservoir and the free end  49  moves within the container during usage, particularly inversion of the container. 
         [0160]      FIG. 31  also differs slightly from  FIG. 30  by increasing the portion of the reservoir  6  of conical shape. The reservoir connects at its tip to the end  50  of the flexible vent extension  46 . This reservoir has a length that greatly exceeds the length of the flexible vent extension as shown. 
         [0161]    And,  FIG. 32  provides a perspective view of the bottom of a closure  5  generally for a wide neck container though adaptable to a narrow neck bottle. The closure  5  has its surface  2  that has an aperture for passing liquids  24  and an aperture for venting air from a container as at  25 . The liquid aperture  24  opens through a spout  4  integrally formed with the closure. The spout is generally a hollow tubular shape. The spout extends away from the surface  2  and opposite the perimeter flange  12 . The spout opens flush at the surface within the flange  12 . In this embodiment, the spout has an internal diameter of its round shape. The spout receives an optional check valve  52 , generally of silicone, and a hollow cylinder. The check valve has two ends, one open and the other opposite end partially closed. The opposite end has two flaps separated by a slit  52   a . The slit widens and the flaps move outwardly upon application of a partial vacuum by a user, such as a suckling infant. Without a partial vacuum, the slit closes the check valve which prevents liquid from passing through the spout. The liquid aperture  24  and hence the spout  4  are generally off center of the closure. Moving to the venting aperture  25 , this aperture is generally centered upon the closure and extends beneath the surface  2  as an optional raised boss  51 . The raised boss has a round cylindrical shape with a thickness less than its diameter. The raised boss forms integrally with the closure. The diameter of the raised boss provides for a press fit connection of a reservoir  6 . The reservoir has its length and then narrows to a reservoir extension  18  as previously described. The venting aperture  25  extends through the surface and the thickness of the raised boss. 
         [0162]    In operation, one connects reservoir  6  to the closure or associated components or aspects, if it is not already present. The reservoir extension is preferably above the level of the liquid in the container B when the container is inverted to empty the liquid from the container. 
         [0163]    This ensures continuous and full venting of the container without aeration and contamination of the liquid in the container. It also ensures the presence of a positive pressure in the container, so that the liquid may be withdrawn from the container on demand, without the interference of vacuum, which is present in traditional containers, other than those of the current inventors. Leakage is also prevented due to the diameters of the pouring aperture, or liquid aperture,  25  and the venting aperture, or air aperture  24 . One range of proportions of internal diameters of the pouring aperture to the venting tube is approximately 2.5:1 (liquid aperture: venting tube internal diameter) and allows for rapid and simultaneous reentry of the liquid inside the venting tube into the container B followed by air entry above the level of liquid when the container is inverted. Optional flanges as at  9 ,  10  are shown. Optional flange  9 , the stop flange, is external to the diameter of the venting tube and maintains the position of the venting tube and reservoir  6 . Optional flange  10 , the retainer flange, is internal to the venting tube and retains any fluid in the venting tube or reservoir  6  while the container is in use. 
         [0164]      FIGS. 3 and 4  are the preferred embodiment of the infant feeding version of the disclosure. The internal venting tube provides an air conduit while keeping the liquid and the air flows separate during usage as the reservoir retains any liquid that moves proximally into the venting tube. The container may contain any type of desired substance and the substance may be dispensed using any type of dispensing device. Some common dispensing devices are nipples in infant feeding bottles and spouts for containers with sports liquids. Any liquid conduit or simply an aperture is frequently used with liquor containers. Any type of dispensing device may be used. Also, the liquid aperture may dispense a solid or liquid substance onto a surface where any amount may accumulate and subsequently be presented at any time and at any desired rate. An example of this type of dispensing is allowing formula or any other liquid to drop onto a spoon shaped device  60  to a certain amount and then feeding an infant with a desired amount of the liquid at a certain rate, as in  FIG. 33 . Alternatively, an aperture in the container or closure or other portion of the substance containing device may be utilized. In all embodiments, all portions of both the air and liquid apertures and their associated components may be integral to various portions of the container or its associated parts, or come in any combination separately or attached. All portions of the apertures and their associated parts may be of any size or configuration that fulfills the requirements of the disclosures. 
         [0165]    Variations or modifications to the subject matter of this disclosure may occur to those skilled in the art upon reviewing the summary as provided herein, in addition to the description of its preferred embodiments. Such variations or modifications, if within the spirit of this development, are intended to be encompassed within the scope of the disclosure as described herein. The description of the preferred embodiment, as well as all embodiments, as provided, and as shown in the drawings, is set forth for illustrative purposes only. 
         [0166]    From the aforementioned description, a container venting mechanism has been described. Thus, for the first time, as demonstrated in all versions of the current disclosure and without utilizing a horizontal air conduit, this vent mechanism is uniquely capable of continuous and full venting, without leaking, and without aerating and contaminating the liquid in the container, while providing a positive pressure in the container, so that liquid may be removed on demand without the interference of vacuum, as seen in traditional containers. This vent mechanism and its various components may be manufactured from many materials, including, but not limited to singly or in combination, polymers, polyester, polyethylene, polypropylene, polyvinyl chloride, nylon, ferrous and non-ferrous metals and their alloys, and composites.
