Definitions
- the present invention relates generally to devices and methods used for mixing at least two fluids, wherein the fluids may be liquids or gases or a combination of both.
- the present invention relates to a venturi device for use in the aeration of wine and a method of use.
- the present invention is directed to a venturi device for use in the aeration of wine when dispensed from a bladder through a valve, such as that found in boxed wine, but should not be limited to that purpose only.
- Wine connoisseurs often expose wine to air, or aerate the wine, prior to drinking. Aeration may be used by connoisseurs to enhance the taste experience, for example, as a way to open up young wines to make them more balanced and smoother by softening tannins, or to improve the expression, harmony, and smoothness of the wine flavor. Aeration is also known to reduce the high carbon dioxide level often found in young wines and the accompanying odor that masks their true aroma. Many wine connoisseurs believe that the flavor of most wine, particularly red wine, improves with aeration by revealing the true complex personality. One method of wine aeration is to simply uncork the bottle and allow the open bottle to sit for the length of time deemed proper for the particular bottle.
- Another aeration method involves the use of a decanter and an aerating funnel. Since a decanter is essentially a pitcher with a wide opening, the increased decanter surface area permits more rapid aeration. The additional use of an aerating funnel during pouring further aids in aeration.
- the bladder and valve system protects the non-dispensed wine from oxidation, from a taste perspective, the arrangement can also be seen as a disadvantage because, as mentioned, aeration of the wine immediately prior to consumption can greatly improve the character and complexity of the wine's flavor and aroma. Furthermore, such boxed wines are relatively large and difficult to maneuver while dispensing wine into a glass. The handling difficulty therefore encumbers the user from dispensing the wine through a hand-held aerator, such as those mentioned, or even through an aerator supported on a stand. Therefore, there is a need for an aeration device for use with bladder types, or other types of fluid dispensing devices, such as those used with box wine.
- the contemplated device provides an inexpensive, easy to produce and package, easy to handle, and reliable device and method for dispensing aerated wine from a bladder or other type of fluid, container without the need for additional expensive and cumbersome external devices. Additionally, since initial aeration of box wine occurs during dispensation, the contemplated device provides a user friendly device for providing efficient and increased aeration and therefore an enhanced wine consumption experience when consuming box wine.
- the present invention provides a novel aeration device and an aeration device which is integrated with, or in-line with a valve, along with a method of using, to thereby improve the flavor of dispensed box wine and consumer perception of quality therewith.
- the present invention overcomes the shortcomings of known box wine dispensing arrangements, including those having valves, by providing an aeration device in the form of a novel venturi apparatus.
- the novel venturi apparatus includes unique air induction passages that minimize leaks or drips.
- the apparatus may be further integrated with a dispensing valve, such as that used with box wine.
- the apparatus creates new and unexpected results due to its ability to aerate wine that has not been previously exposed to air by using only the internal head pressure provided by the box wine or other container type.
- the present invention is directed to an improved venturi device that may be attachable to, or integrated with, a dispensing valve or spout of a fluid filled bladder, and a method of using.
- the device promotes the assimilation and mixing of the bladder fluid with another fluid, such as during aeration of wine.
- the device preferably includes a central bore and at least one induction passage which is arranged for either radial or tangential fluid connection from the periphery of the device to the central bore.
- the induction passage is preferably positioned at an angle greater than zero from the plane perpendicular to the direction of flow.
- Another objective of the invention is to provide a dispensing valve having an integrally formed, venturi device that is easily produced at low cost using common molding technology.

- FIG. 12 is a partial section view of the device illustrated in FIG. 9 but showing the device integrally molded with a dispensing valve.
- FIG. 13 is a perspective view of another embodiment of the venturi device shown with an alternative attachment means.
- FIG. 1 depicts an embodiment of a venturi device 10 according to the present invention having a body 14 , the body including a first end 16 , a second end 18 , an outer periphery 22 , a central bore 40 A, and at least one induction passage 20 A.
- the first end 16 further includes a mating interface portion 12 .
- the body 14 is preferably cylindrical, however, it should be noted that the body 14 may be fabricated in any number of shapes and designs without affecting the aerating performance of the device 10 or departing from the spirit of the invention.
- the central bore 40 A preferably includes a first diameter D 1 , a second diameter D 2 , and a third diameter D 3 .
- the third diameter D 3 is preferably larger than the second diameter D 2 and the first diameter D 1 is preferably larger than the third diameter D 3 .
- a first induction passage 20 A and a second induction passage 20 B each having an entrance 24 A, 24 B and an exit 26 A, 26 B, respectively, provide pathways from the outer periphery 22 of the body 14 to the central bore 40 A.
- the induction passages 20 A, 20 B are preferably angled, such that their respective entrances 24 A, 24 B are closer than the exits 26 A, 26 B to the first end 16 of the body 14 with the passages 20 A, 20 B being positioned at an angle greater than zero from the plane perpendicular to axis of the central bore 40 A. It may be further noted, and as seen in FIGS. 2B and 2C , that the induction passages 20 A, 20 B may extend radially outward or alternatively, tangentially from the central bore 40 A to the outer periphery 22 .
- the device 10 seen FIG. 1 is shown attached to a dispensing valve 32 A on a box container 50 such as that used, to dispense box wine.
- a container 50 typically houses a fluid retaining bladder 54 and includes known valves 32 A, such as those disclosed in U.S. Pat. No. 6,296,157 and manufactured by Scholle Corporation, or those offered by Rapak, for example.
- the venturi device 10 may be attached to the output portion 13 (see FIG. 6 ) of dispensing valve 32 A. in several acceptable manners.
- the mating interface 12 of device 10 may be provided with a threaded portion 34 .
- the threaded portion 34 may be adapted for mating engagement with a respective threaded portion (not shown) of a mating dispensing valve 32 A.
- the device 10 may include a mating interface 12 manufactured of a flexible elastomer and having a rib 38 or a groove (not shown) for mating engagement with a dispensing valve 32 A having a corresponding groove (not shown) or a rib (not shown), respectively, via a snap-fit.
- Other means of attachment include: friction welding, thermal welding, cementing, or press-fitting the mating interface 12 of the venturi device 10 to the dispensing valve 32 A, by way of non-limiting examples.
- the venturi device 10 , 210 may be integrally molded with the dispensing valve 32 A. Further, and as viewed in FIG. 13 , it is within the scope of the invention to attach the device 310 via external means, as when a beverage dispensing nozzle 52 is used.
- a user's hand 60 is shown dispensing a fluid mixture 36 , such as aerated wine, from the dispensing valve 32 A, through the venturi device 10 , and into a glass 62 .
- a fluid mixture 36 such as aerated wine
- the method of mixing a first and second fluid for dispensing as the fluid mixture 36 shown, is illustrated in detail in the view of FIG. 6 .
- a first fluid 28 such as wine, exits the dispensing valve 32 A in the direction of arrow A, and into the first end 16 of the venturi device 10 .
- first diameter D 1 is relative to the second diameter D 2 the larger the increase in velocity of the first fluid 28 as it passes through the central bore 40 A, and thus the greater the mixing potential with the second fluid 30 .
- the actual diameters D 1 , D 2 , D 3 useful with the present invention may be varied depending on factors such as the required interface of the venturi device 10 with various dispensing valves 32 A, the desired dispensation flow, or manufacturing and machining considerations.
- FIG. 2C a tangential orientation of the induction passages 20 A, 20 B may be seen.
- the tangential arrangement with the central bore 40 A imparts a rotational effect, or vortex v x , in the first fluid 28 (not shown in this view) as it mixes with the second fluid 30 (see FIG. 6 ).
- the vortex v x if properly utilized, can increase the mixing of the two fluids 28 , 30 providing better aeration.
- the device 110 shown in FIGS. 7 and 8 includes a body 14 having a first end 16 , a second end 18 , an outer periphery 22 , a mating interface 12 , and at least one induction passage 20 .
- the embodiment 110 shown includes a second, end 18 having an elongated, tapered portion 48 , and a relatively larger central bore 40 B as compared to the previous embodiment.
- the device 110 may include at least one induction passage, seen in these views as 20 C, which is positioned relatively closer to the first end 16 as compared to passages 20 .
- the location of induction, passage 20 C promotes additional aeration as the head pressure of the first fluid 28 drops due to the emptying of the box wine container 50 (see FIG. 3 ) and thereby enables continued function of the device 110 under the low or falling head pressure head pressure associated with bladder type fluid containers 50 .
- the position of the entrance 24 C of induction passage 20 C in addition to its location nearer the first, end 16 than passage 20 , may be advantageously positioned in the outer periphery 22 in line with the tapered portion 48 , Positioning the entrance 24 C of passage 20 C in line with the tapered portion 48 further facilitates complete dispensation of the fluid mixture 36 after the valve 32 A is closed, as will be further discussed.
- the embodiment 110 illustrated in FIGS. 7 and 8 provides an alternative device for more easily aerating wine from a wine box 50 or other type of bladder container in conjunction with a dispensing valve 32 A.
- the tapered end portion 48 of the device 110 promotes facile and complete wine dispensation after the dispensing valve 32 A (see FIG. 6 ) is closed.
- the tapered portion 48 serves to direct residual mixed fluid 36 remaining in the central bore 40 B along the third, diameter D′ 3 , to thereby collect any residual fluid 36 at the tapered portion 48 and allowing any residual mixed fluid 36 to gain mass and drop.
- This feature reduces post valve 32 A closure dripping of mixed fluid 36 and decreases the likelihood of delayed post dispensing drips and any mess that may follow.
- Improved efficiency of the tapered, portion 48 may be observed when, as mentioned earlier, passage 20 C is positioned in line with the tapered portion 48 , to thereby promote more thorough collection of residual mixed fluid 36 .
- FIGS. 9-11C Another embodiment of the venturi device 210 is shown in FIGS. 9-11C .
- the device 210 shown in FIGS. 9 and 10 , includes a body 14 having a first end 16 , a second, end 18 , an outer periphery 22 , and at least one induction passage 20 A.
- the device 210 further includes a second end 18 having an elongated, tapered end portion 48 .
- FIG. 9 Another embodiment of the venturi device 210 is shown in FIGS. 9-11C .
- the device 210 shown in FIGS. 9 and 10 , includes a body 14 having a first end 16 , a second, end 18 , an outer periphery 22 , and at least one induction passage 20 A.
- the device 210 further includes a second end 18 having an elongated, tapered end portion 48 .
- the device 210 includes a central bore 40 C having a first diameter D′′ 1 and a second diameter D′′ 2 , wherein the first and second diameters D′′ 1 , D′′ 2 are of substantially the same size. As shown, the device 210 may further include induction passages 20 C and 20 D. As viewed particularly in FIG. 12 , the arrangement of alternative embodiment 210 is well suited, to be integrally molded with the dispensing valve 32 A due to manufacturing and molding considerations. For example, with the first and the second diameters D′ 1 , D′ 2 , respectively, of substantially the same size, the use of a single molding pin (not shown) during manufacturing may be utilized. The molding pin may be extracted from the second end 18 after molding to permit a simpler manufacturing process.
- the modification of the device 210 as shown and compared to that in FIG. 1 permits a simpler manufacture since the device 10 would likely require two molding pins (not shown), one for each end 16 , 18 .
- the device 10 , 110 , 210 could be attached to a valve 32 A by way of cementitious bonding, snap fit assembly, thermal, welding, threading, press-fitting, or other attachment means known to those skilled in the art.
- the alternative embodiment 210 includes induction passages 20 C and 20 D to thereby ameliorate the velocity loss caused by the lack of a diameter D′′ 1 , D′′ 2 differential.
- the induction passages 20 C, 20 D cause the rate of induction of the second fluid 30 into the first fluid 28 to increase, and thereby allow the device 210 to provide the required increased aeration.
- FIGS. 11B and 11C further illustrate alternative relative positions of the induction passages 20 C and 20 D and the induction passages 20 A and 20 B to demonstrate that different passage 20 A, 20 B, 20 C, 20 D orientations are possible while remaining under the scope of the present invention.
- the device 310 may be envisioned for use in combination with a beverage dispensing nozzle 52 and for use with an alternative dispenser 32 B.
- the device 310 preferably includes an external attachment means, such as the securing mechanism 42 shown.
- the device 310 shown in FIG. 13 includes a body 14 with a first end 16 and a second end 18 , mating interface 12 at the first end 16 , and an elongated tapered end portion 48 at the second end 18 , and at least one induction passage 20 .
- FIG. 13 the device 310 shown in FIG. 13 includes a body 14 with a first end 16 and a second end 18 , mating interface 12 at the first end 16 , and an elongated tapered end portion 48 at the second end 18 , and at least one induction passage 20 .
- FIG. 13 the device 310 shown in FIG. 13 includes a body 14 with a first end 16 and a second end 18 , mating interface 12 at the first end 16 , and an elongated tapered end portion 48 at the

Abstract
An improved venturi device for facilitating the mixture of fluid substances, such as wine and air. The device may be combined with a dispensing valve to further promote functionality. The improved venturi device is especially effective in drawing a second fluid into the primary flow of a first fluid, and when combined with a dispensing valve it obviates the need for a venturi independent from a valve to accomplish mixing at low flows and low liquid head pressure.
Description
- This application claims the benefit of provisional application Ser. No. 61/443,370 filed 16 Feb. 2011.
- The present invention relates generally to devices and methods used for mixing at least two fluids, wherein the fluids may be liquids or gases or a combination of both. Particularly, the present invention relates to a venturi device for use in the aeration of wine and a method of use. Specifically, the present invention is directed to a venturi device for use in the aeration of wine when dispensed from a bladder through a valve, such as that found in boxed wine, but should not be limited to that purpose only.
- Wine connoisseurs often expose wine to air, or aerate the wine, prior to drinking. Aeration may be used by connoisseurs to enhance the taste experience, for example, as a way to open up young wines to make them more balanced and smoother by softening tannins, or to improve the expression, harmony, and smoothness of the wine flavor. Aeration is also known to reduce the high carbon dioxide level often found in young wines and the accompanying odor that masks their true aroma. Many wine connoisseurs believe that the flavor of most wine, particularly red wine, improves with aeration by revealing the true complex personality. One method of wine aeration is to simply uncork the bottle and allow the open bottle to sit for the length of time deemed proper for the particular bottle. While this method has been used for years, it is inefficient and causes the drinker to wait for the requisite time, and further, the narrow bottleneck may encumber most air from opening up the wine. If time is not a concern, the connoisseur may simply let the wine aerate slowly in a glass. Another aeration method involves the use of a decanter and an aerating funnel. Since a decanter is essentially a pitcher with a wide opening, the increased decanter surface area permits more rapid aeration. The additional use of an aerating funnel during pouring further aids in aeration.
- Other methods of wine aeration include the use of aeration devices marketed specifically for the wine enthusiast. Some, such as those marketed under the RABBIT®, SOIREE™, and RESPIRER® trademarks, provide aeration using a vortex generator to swirl the wine. A popular device, marketed under the trademark VINTURI®, and disclosed, in U.S. Pat. No. 7,614,614, produces an aerated wine using a venturi device that is hand-held or placed in a holding stand while the wine is poured through it. While devices such as this may have some applicability, they can be awkward to manipulate. For example, a drawback to designs such as these is that the user must be especially careful to control and limit, the flow from the bottle to avoid overflow of the entrance section. Another problem is that the user must pour accurately into the entrance section to prevent wine from flowing out of the air entry passages. This creates an unsanitary and unpleasant experience for the user.
- Furthermore, rigid boxes containing a flexible bladder holding a liquid such as wine have become a popular method of marketing and selling such products, The containers are usually sold in 3 liter or larger sizes. While aeration of wine prior to consumption is desirable, oxidation and spoilage may occur if wine is in contact with oxygen for extended periods. Box wines are advantageous since the consumer is able to dispense “fresh” wine over a long period of time as compared with bottled wine which must be consumed relatively quickly or risk spoilage. The advantage of bladder-contained box wine results from the wine in the bladder being protected from exposure to oxygen prior to dispensing. This protection is furthered by incorporation of a valve mechanism that prohibits oxygen from entering the bladder. Although the bladder and valve system protects the non-dispensed wine from oxidation, from a taste perspective, the arrangement can also be seen as a disadvantage because, as mentioned, aeration of the wine immediately prior to consumption can greatly improve the character and complexity of the wine's flavor and aroma. Furthermore, such boxed wines are relatively large and difficult to maneuver while dispensing wine into a glass. The handling difficulty therefore encumbers the user from dispensing the wine through a hand-held aerator, such as those mentioned, or even through an aerator supported on a stand. Therefore, there is a need for an aeration device for use with bladder types, or other types of fluid dispensing devices, such as those used with box wine.
- The contemplated device provides an inexpensive, easy to produce and package, easy to handle, and reliable device and method for dispensing aerated wine from a bladder or other type of fluid, container without the need for additional expensive and cumbersome external devices. Additionally, since initial aeration of box wine occurs during dispensation, the contemplated device provides a user friendly device for providing efficient and increased aeration and therefore an enhanced wine consumption experience when consuming box wine. The present invention provides a novel aeration device and an aeration device which is integrated with, or in-line with a valve, along with a method of using, to thereby improve the flavor of dispensed box wine and consumer perception of quality therewith.
- Venturi devices are well known in the art of measuring fluid flow and mixing fluids. Without exception, they include an entrance section, a constricted middle section, and an exit section. In operation, as a fluid flowing at a certain velocity in the entrance section encounters the constricted middle section, the fluid velocity will correspondingly increase according to the continuity equation: Q=V1A1=V2A2, where Q is the constant flow rate, V is the mean velocity of the flow, and A is the cross sectional area of the flow. Generally, a second fluid may be introduced into the fluid stream at the constricted middle section where the increased velocity has created, a pressure differential between the outside of the venturi and the intermediate fluid passage.
- The present invention overcomes the shortcomings of known box wine dispensing arrangements, including those having valves, by providing an aeration device in the form of a novel venturi apparatus. The novel venturi apparatus includes unique air induction passages that minimize leaks or drips. The apparatus may be further integrated with a dispensing valve, such as that used with box wine. Furthermore, the apparatus creates new and unexpected results due to its ability to aerate wine that has not been previously exposed to air by using only the internal head pressure provided by the box wine or other container type.
- The present invention is directed to an improved venturi device that may be attachable to, or integrated with, a dispensing valve or spout of a fluid filled bladder, and a method of using. The device promotes the assimilation and mixing of the bladder fluid with another fluid, such as during aeration of wine. The device preferably includes a central bore and at least one induction passage which is arranged for either radial or tangential fluid connection from the periphery of the device to the central bore. The induction passage is preferably positioned at an angle greater than zero from the plane perpendicular to the direction of flow.
- It is an objective of the invention to provide a venturi which is adapted for use in providing an aerated fluid as it is dispensed from a container, obviating the need for an independent, secondary aeration device.
- It is another objective of the invention to provide a venturi which is adapted for use in combination with a valve to thereby provide an aerated fluid as it dispensed from a valved container.
- It is a further objective of the invention to provide a method of fluid aeration, at low fluid flows and low head pressure, during fluid dispensing from a bladder type container.
- It is yet another objective of the present invention to combine a valve with an attachable or integrally molded venturi, to provide an aerated fluid as dispensed from a bladder type container.
- Another objective of the invention is to provide a dispensing valve having an integrally formed, venturi device that is easily produced at low cost using common molding technology.

- Referring to the drawings, wherein like numerals represent like parts throughout the views,
FIG. 1 depicts an embodiment of aventuri device 10 according to the present invention having abody 14, the body including afirst end 16, asecond end 18, anouter periphery 22, acentral bore 40A, and at least oneinduction passage 20A. Thefirst end 16 further includes amating interface portion 12, As further illustrated inFIG. 1 , thebody 14 is preferably cylindrical, however, it should be noted that thebody 14 may be fabricated in any number of shapes and designs without affecting the aerating performance of thedevice 10 or departing from the spirit of the invention. - With reference now to
FIG. 2A , a cross-sectional view of theventuri device 10 shown inFIG. 1 may be seen. As viewed, thecentral bore 40A preferably includes a first diameter D1, a second diameter D2, and a third diameter D3. As may be further seen inFIG. 2A , the third diameter D3 is preferably larger than the second diameter D2 and the first diameter D1 is preferably larger than the third diameter D3. As further illustrated, afirst induction passage 20A and asecond induction passage 20B each having anentrance 24A, 24B and anexit outer periphery 22 of thebody 14 to thecentral bore 40A. As shown, theinduction passages respective entrances 24A, 24B are closer than theexits first end 16 of thebody 14 with thepassages central bore 40A. It may be further noted, and as seen inFIGS. 2B and 2C , that theinduction passages central bore 40A to theouter periphery 22. - With particular attention to
FIG. 3 , thedevice 10 seenFIG. 1 is shown attached to a dispensingvalve 32A on abox container 50 such as that used, to dispense box wine. Such acontainer 50 typically houses afluid retaining bladder 54 and includes knownvalves 32A, such as those disclosed in U.S. Pat. No. 6,296,157 and manufactured by Scholle Corporation, or those offered by Rapak, for example. Theventuri device 10 may be attached to the output portion 13 (seeFIG. 6 ) of dispensing valve 32A. in several acceptable manners. For example, and as seen inFIG. 4A , themating interface 12 ofdevice 10 may be provided with a threadedportion 34. As shown, the threadedportion 34 may be adapted for mating engagement with a respective threaded portion (not shown) of amating dispensing valve 32A. Alternatively, and as seen inFIG. 4B , thedevice 10 may include amating interface 12 manufactured of a flexible elastomer and having arib 38 or a groove (not shown) for mating engagement with a dispensingvalve 32A having a corresponding groove (not shown) or a rib (not shown), respectively, via a snap-fit. Other means of attachment include: friction welding, thermal welding, cementing, or press-fitting themating interface 12 of theventuri device 10 to the dispensingvalve 32A, by way of non-limiting examples. Alternatively, and as seen inFIG. 12 , theventuri device valve 32A. Further, and as viewed inFIG. 13 , it is within the scope of the invention to attach thedevice 310 via external means, as when abeverage dispensing nozzle 52 is used. - Turning now to
FIG. 5 , a user'shand 60 is shown dispensing afluid mixture 36, such as aerated wine, from the dispensingvalve 32A, through theventuri device 10, and into aglass 62, The method of mixing a first and second fluid for dispensing as thefluid mixture 36 shown, is illustrated in detail in the view ofFIG. 6 . As shown, afirst fluid 28, such as wine, exits the dispensingvalve 32A in the direction of arrow A, and into thefirst end 16 of theventuri device 10. According to the continuity equation, Q=V1A1=V2A2, the larger the first diameter D1 is relative to the second diameter D2, the greater the velocity increase of thefirst fluid 28 flowing through thecentral bore 40A in the direction of arrow A. Further, with a greater increase in velocity comes a greater reduction in pressure, thus allowing a greater induction of asecond fluid 30, such as ambient air, through theinduction passages mixture 36. Themixture 36 of thefirst fluid 28 and thesecond fluid 30 then exits through thesecond end 18 of theventuri device 10 in the direction of arrow C. It is to be understood that the larger the first diameter D1 is relative to the second diameter D2 the larger the increase in velocity of thefirst fluid 28 as it passes through thecentral bore 40A, and thus the greater the mixing potential with thesecond fluid 30. An example of non-limiting approximate relative diameters workable with thedevice 10 may be D1=0.28″, D2=0.17″, and D3=0.23″. It is to be understood that the listed diameters are meant for illustration only and not to limit the invention. The actual diameters D1, D2, D3 useful with the present invention may be varied depending on factors such as the required interface of theventuri device 10 with various dispensingvalves 32A, the desired dispensation flow, or manufacturing and machining considerations. - Now referring back to
FIG. 2C , a tangential orientation of theinduction passages central bore 40A imparts a rotational effect, or vortex vx, in the first fluid 28 (not shown in this view) as it mixes with the second fluid 30 (seeFIG. 6 ). The vortex vx, if properly utilized, can increase the mixing of the twofluids - With reference now to
FIGS. 7 and 8 , analternative embodiment 110 may be seen. Similar to thedevice 10 shown and discussed with reference toFIGS. 1-6 , thedevice 110, shown inFIGS. 7 and 8 includes abody 14 having afirst end 16, asecond end 18, anouter periphery 22, amating interface 12, and at least oneinduction passage 20. However, and as illustrated inFIGS. 7 and 8 , theembodiment 110 shown includes a second, end 18 having an elongated,tapered portion 48, and a relatively largercentral bore 40B as compared to the previous embodiment. As may be further viewed, thedevice 110 may include at least one induction passage, seen in these views as 20C, which is positioned relatively closer to thefirst end 16 as compared topassages 20. The location of induction,passage 20C promotes additional aeration as the head pressure of thefirst fluid 28 drops due to the emptying of the box wine container 50 (seeFIG. 3 ) and thereby enables continued function of thedevice 110 under the low or falling head pressure head pressure associated with bladdertype fluid containers 50. It may also be seen that the position of theentrance 24C ofinduction passage 20C, in addition to its location nearer the first, end 16 thanpassage 20, may be advantageously positioned in theouter periphery 22 in line with the taperedportion 48, Positioning theentrance 24C ofpassage 20C in line with the taperedportion 48 further facilitates complete dispensation of thefluid mixture 36 after thevalve 32A is closed, as will be further discussed. - The
embodiment 110 illustrated inFIGS. 7 and 8 provides an alternative device for more easily aerating wine from awine box 50 or other type of bladder container in conjunction with a dispensingvalve 32A. Thecentral bore 40B having relatively larger diameters D′1, D′2, D′3, along with the placement, ofpassage 20C, permits an increased flow rate if so desired. An example of non-limiting approximate relative diameters workable with thedevice 110 includes D′1=0.48, D′2=0.203, and D′3=0.30, however, it is to be understood that the actual diameters D′1, D′2, D′3 may be varied, without departing from the invention. Further, thetapered end portion 48 of thedevice 110 promotes facile and complete wine dispensation after the dispensingvalve 32A (seeFIG. 6 ) is closed. The taperedportion 48 serves to direct residualmixed fluid 36 remaining in thecentral bore 40B along the third, diameter D′3, to thereby collect anyresidual fluid 36 at the taperedportion 48 and allowing any residualmixed fluid 36 to gain mass and drop. This feature reduces postvalve 32A closure dripping ofmixed fluid 36 and decreases the likelihood of delayed post dispensing drips and any mess that may follow. Improved efficiency of the tapered,portion 48 may be observed when, as mentioned earlier,passage 20C is positioned in line with the taperedportion 48, to thereby promote more thorough collection of residualmixed fluid 36. - Another embodiment of the
venturi device 210 is shown inFIGS. 9-11C . Similarly to thedevices FIGS. 1-6 and 7 and 8, thedevice 210, shown inFIGS. 9 and 10 , includes abody 14 having afirst end 16, a second, end 18, anouter periphery 22, and at least oneinduction passage 20A. Thedevice 210 further includes asecond end 18 having an elongated,tapered end portion 48. However, and as may be seen particularly inFIG. 11A , thedevice 210 includes acentral bore 40C having a first diameter D″1 and a second diameter D″2, wherein the first and second diameters D″1, D″2 are of substantially the same size. As shown, thedevice 210 may further includeinduction passages FIG. 12 , the arrangement ofalternative embodiment 210 is well suited, to be integrally molded with the dispensingvalve 32A due to manufacturing and molding considerations. For example, with the first and the second diameters D′1, D′2, respectively, of substantially the same size, the use of a single molding pin (not shown) during manufacturing may be utilized. The molding pin may be extracted from thesecond end 18 after molding to permit a simpler manufacturing process. The modification of thedevice 210 as shown and compared to that inFIG. 1 , permits a simpler manufacture since thedevice 10 would likely require two molding pins (not shown), one for eachend device valve 32A by way of cementitious bonding, snap fit assembly, thermal, welding, threading, press-fitting, or other attachment means known to those skilled in the art. Alternatively, it is within the scope of the present, invention to mold, thevalve 32A and thedevice 10 together as a singular unit. - With further reference to
FIG. 11A , thedevice 210 may be seen to includeinduction passages alternative device 210 has a first diameter D′1 of substantially the same dimension as the second diameter D′2, some loss of induction of thesecond fluid 30 into thefirst fluid 28 may be observed. As stated earlier, and with reference toFIG. 6 , according to the continuity equation, Q=V1A1=V2A2, the larger the first, diameter D1 is relative to the second diameter D2, the greater the velocity of thefirst fluid 28 flowing through the central bore 40 in the direction of arrow A and the higher the level of aeration. Without a significant difference in relative diameters D″1, D″2, some aeration may be lost. However, thealternative embodiment 210 includesinduction passages induction passages second fluid 30 into thefirst fluid 28 to increase, and thereby allow thedevice 210 to provide the required increased aeration.FIGS. 11B and 11C further illustrate alternative relative positions of theinduction passages induction passages different passage - Turning now to
FIG. 13 , anotherembodiment 310 is shown. As illustrated, thedevice 310 may be envisioned for use in combination with abeverage dispensing nozzle 52 and for use with analternative dispenser 32B. When used in the manner shown inFIG. 13 , thedevice 310 preferably includes an external attachment means, such as the securingmechanism 42 shown. Similar to thedevices device 310 shown inFIG. 13 includes abody 14 with afirst end 16 and asecond end 18,mating interface 12 at thefirst end 16, and an elongatedtapered end portion 48 at thesecond end 18, and at least oneinduction passage 20. However, as may be seen inFIG. 13 , theembodiment 310 further includes asecuring mechanism 42 to attach thedevice 310 to analternative dispenser 32B, such as thenozzle 52 shown. As illustrated, thedevice 310 preferably includes aportion 52 of thefirst end 16 configured to provide an interface between a portion of theouter periphery 22 and theexternal securing mechanism 42, Additionally, theexternal securing mechanism 42 may be equipped. with interlockingarms 44 or, in the alternative, a continuous loop configuration (not shown) made from an elastomeric material to provide a secure attachment of thedevice 310 to the dispensingvalve 32B. These two non-limiting examples of theexternal securing mechanism 42 further allow for attachment and removal of thedevice 310 from the dispensingvalve 32B. Furthermore, a seal may be provided between thedevice 310 and the dispensingvalve 32B by way of conformable elastomeric sealing means such as a gasket or the o-ring 46 shown. - As previously mentioned, the present invention further provides a method of mixing two fluids and dispensing a mixture of the two fluids. A method according to the present invention, seen in particularly in the view of
FIG. 6 , may include the steps of: providing a first, fluid 28, the first, fluid 28 being confined within a bladder 54; providing the bladder 54 with a dispensing valve 32, the dispensing valve 34 being operable in open and closed positions and including an output portion 13; providing a venturi device 10, the venturi device 10 including a body 14 having a first end 16, a second end 18, a central bore 40, at least one induction passage 20, and an outer periphery 22; providing the first end 16 of the venturi device 10 with a mating interface 12; providing the at least, one induction passage 20 with an entrance 24 and an exit 26, wherein the entrance 24 interfaces with the outer periphery 22 of the device 10 and wherein the exit 26 interfaces with the central bore 40; interfacing the mating interface 12 of the venturi device 10 with the output portion 13 of the dispensing valve 32; opening the dispensing valve 32; moving the first fluid 28 from the bladder 54 through the output 13 of the dispensing valve 32 and into the first end 16 of the venturi device 10; moving the first fluid 28 through the central bore 40 of the venturi device 10; providing a second fluid 30; moving the second fluid 30 through the entrance 24 of the at least one induction passage 20 and toward the central bore 40 of the venturi device 10; mixing the first fluid 28 and the second fluid 30 in the central bore 40 to thereby provide a third, mixed fluid 36; moving the third fluid 36 through the central bore 40 and toward the second end 18; and closing the dispensing valve 32. - As demonstrated, the present invention provides a

Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described. While the preferred embodiment has been described, the details may be changed.
