Beverage dispenser and stand therefore for use with beverage containing bottles

An apparatus for dispensing liquids directly from a vertically oriented inverted container comprises a body to secure to the mouth of the container. The body defines a pair of first and second chambers that communicate with a pair of first and second passageways. A pair of valves is adapted to selectively open and close the first and second chambers. Finally, a valve control mechanism is operative linked to the valves and sequentially opens the second valve and the first valve.

TECHNICAL FIELD 
This invention relates to an apparatus and stand for the selectively 
dispensing of carbonated and uncarbonated beverages from a disposable 
bottle. 
BACKGROUND OF THE INVENTION 
One of the common complaints of individuals or entities about group events 
where beverages are served from bottles such as the one and two liter soft 
drink bottles to a large number of guests or patrons is the time involved 
in serving each individual. Unless the server uses expensive beverage 
serving equipment, for example, pump or pressure driven devices such as 
often found in taverns or the like, considerable time is involved in 
identifying the appropriate container, pouring the beverage in a suitable 
receptacle, and serving the beverage. Spillage often occurs and is 
particularly exacerbated if the user is a child trying to cope with the 
relative large size of the bottle. Additionally, attendant waste is likely 
to occur since frequently more bottles than necessary are opened. Even 
where bottles containing carbonated beverages only partially consumed are 
recapped, the remaining liquids become less effervescent due to escape of 
the constituent gas into the now larger ullage volume of the bottles. 
Thus, it is very desirable that the opened bottles be consumed in close 
time proximity of opening and that other bottles be kept in reserve until 
actually needed. 
There have been numerous attempts to cope with this nettlesome problem 
through the use of beverage dispensers that dispense the beverage 
selectively and maintain a seal on the container to preserve the freshness 
of the liquid during the selective dispensing operation. One example is 
found in U.S. Pat. No. 4,722,463 issued Feb. 2, 1988 to Anderson. The 
Anderson patent describes an apparatus containing a spring biased plug 
element that has an annular groove with a significant axial length. The 
plug element is axially movable through the manual manipulation of a 
lever. The groove communicates with both the interior of the bottle and a 
spout mechanism when a lever cams the plug into an open position. The 
spout mechanism is used to divert and direct the flow of a liquid into an 
awaiting receptacle such as a glass. Release of the lever causes the plug 
to return to its closed position under the bias exerted by the spring, 
taking the annular groove out of communication with the spout. The 
beverage in the bottle is caused to change direction several times while 
flowing under gravity from the container to the spout. For example, the 
beverage must flow from the bottle into the groove, out of the groove into 
the spout, and then into the glass. Carbonated beverages, however, are 
adversely affected when the downward moving liquid impacts various 
internal barriers to the flow, causing it to release its carbonation. Due 
to the small diameter and volume of the passageways within the prior art 
dispenser, considerable build up in the gas pressure can occur quickly 
causing a rapid expulsion of the gas and a concomitant noise. If the 
venting passageways cannot accommodate quickly enough the gaseous 
equilibration between the ullage volume of the container and the 
atmosphere, the liquid itself may be expelled through the liquid 
passageways under pressure causing splatter and undesirable quantities of 
foam. 
Still another example is found in U.S. Pat. No. 4,715,516 issued Dec. 29, 
1987 to Salvail. This patent recognizes the desirability to allow the gas 
in the ullage volume of the bottle to equilibrate prior to allowing the 
liquid to flow out of the bottle. The sequence is accomplished through the 
use of valves opening and closing the passageways between the bottle and 
the spout egress from the dispensing apparatus to the awaiting beverage 
receptacle. Each valve is separately spring biased into the closed 
position and are opened sequentially by a lever camming against the bottom 
of the valve stems. The valve stem of the vent passageway is longer than 
the valve stem of the liquid passageway and is contacted by the lever 
prior to contact with the liquid valve stem, thus allowing the pressure in 
the ullage volume to equilibrate prior to the liquid being allowed to 
egress. It should be noted, however, that the structure of the Salvail 
device, like that of the Anderson dispensing device, requires the liquid 
to abruptly change direction at least twice as it flows toward the spout. 
Again, the abrupt change in direction of the liquid caused by the impact 
thereof against various internal members results in the constituent gas in 
the unstable carbonated liquid to be undesirable released prior to 
consumption, giving rise to excess foam and flat tasting beverages. 
Salvail further is typical of prior art devices in which the liquid and 
air mix at a point somewhere in the device, causing carbonated liquids to 
cavitate and prematurely release its carbonation. 
Salvail also describes a stand, typical of other prior art stands, that is 
connected to the bottle about its neck. It is noted that the stand is 
subjected to considerable torque due to the displacement of the center of 
gravity from the point of contact with the stand. This represents a 
possible unstable condition as the stand and bottle can easily be tipped 
over by outside forces. Additionally, it may be difficult to accommodate 
bottles of different dimensions. 
It is therefore one object of the present invention to provide for a 
beverage dispensing apparatus for the rapid flow of beverage from bottle 
to receptacle without undue creation of foam or causing the beverage to 
taste "flat". 
It is still another object of the present invention to provide for a 
beverage dispenser for the sequential, unimpeded equilibration of the 
ullage volume of a container and the unimpeded dispensing of the liquid 
therein in a direct unimpeded vertical flow to the receptacle. 
It is a further object of the present invention to provide for a beverage 
dispenser that is compact and provides for liquid and venting chambers 
large enough to ensure that the pressure in the ullage volume is fully 
dissipated before the liquid is permitted to flow to the receptacle. 
It is still a further object of the present invention to provide for a 
beverage dispenser capable of accommodating and dispensing liquid from an 
open and inverted beverage bottle that is vertically positioned above a 
receptacle. 
It is still another object of the present invention to provide for a 
combination stand and beverage dispenser in which the stand directly 
supports a dispenser that is sealed to the opening of an inverted bottle 
containing a beverage. 
SUMMARY OF THE INVENTION 
To accommodate the objects of the invention listed above, an apparatus for 
dispensing liquids directly from a vertically oriented inverted container 
containing a liquid comprises a body adapted to receive and secure the 
open mouth of the container. The body further defines a pair of spaced 
chambers with a first chamber communicating directly through the mouth 
with the liquid in the container and the second chamber communicating 
directly with the ullage volume of the container via a hollow tube-like 
member. The body further defining first and second spaced passageways that 
communicate with the respective chambers. The first passageway is 
vertically aligned beneath said first chamber so as to permit unimpeded 
flow of liquid therethrough when open. A pair of valves is adapted to 
selectively open and close the first and second passageways. Finally, a 
valve control mechanism is operative linked to the valves and sequentially 
opens the second valve and then the first valve. The sequential operation 
permits the unimpeded equilibration of the pressure in the ullage volume 
prior to the unimpeded dispensing of fluid from the bottle to the awaiting 
receptacle. 
Still another feature of the present invention is a stand used in 
combination with the beverage dispenser that connects directly to one or 
more beverage dispensers and permits one or more bottles to be inverted 
and positioned substantially vertical with respect to the horizontal for 
the dispensing of liquids. The stand includes an upright column mounted on 
a pedestal positioned on a horizontal support surface such as a counter 
top. A pair of arms mounted to the top of the upright member extend 
horizontally outward from the column in opposite directions. Each arm is 
bent so as to form a rounded right angle bend creating forward extending 
arm portion. The distal ends of the forward extending portions are 
bifurcated into pairs of spaced and parallel fingers, thus providing a 
yoke-like dispenser grasping member. The spacing between the fingers of 
the member is large enough to allow the dispenser to slide therebetween. 
The dispenser is provided with a pair of flanges, the underneath surface 
thereof resting against the top surface of the fingers thereby providing a 
support for the dispensing apparatus and the connected bottle. Because the 
stand directly supports the body of the dispensing apparatus, it is 
independent of the size and shape of the bottle and accommodates the use 
of all sizes of bottles. 
Other objects of the present invention will become readily apparent to 
those skilled in the art from the following description and appended 
drawing wherein there is shown and described a preferred embodiment of the 
present invention. As it will be realized, the invention is capable of 
other and different embodiments, and its several details are capable of 
modifications in various, obvious aspects, all without departing from the 
invention. Accordingly, the drawing and descriptions will be regarded as 
illustrative in nature and not as restrictive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
As illustrated by FIG. 1, a pair of dispensing apparatus 10 are supported 
by a stand 12. One apparatus 10 is connected to an inverted bottle 14 with 
its sealing cap removed and contains a liquid 16. While FIG. 1, for clarity 
shows a single bottle in position, stand 12 is capable of two dispensing 
apparatus 10, each adapted to be connected to a bottle. The open mouth of 
bottle 14 is secured within annular boss or collar 18 fixed to top wall 20 
of apparatus 10. Collar 18 is provided with internal threads to mesh with 
the external threads about the throat of bottle 14. 
Top wall 20 extends beyond the body 26 to form a flange 21. Spaced beneath 
flange 21 a predetermined distance is a second flange or ridge 21a (best 
seen in FIG. 2). As discussed below, flange 21 serves as a supporting 
element of apparatus 10 by stand 12. Ridge 21a prevents accidental tipping 
of bottle 14 and apparatus 10 when positioned on stand 12. 
Stand 12, adapted to be positioned on a horizontal surface by C or U-shaped 
pedestal 13, supports apparatus 10 and indirectly bottle 14 through 
dispenser 10. A vertical support column 15 is removably secured at its 
lower end within adjustable socket connection 17 located at the midpoint 
of pedestal 13. Extending in opposite directions from removable sleeve 
member 19 encapsulating the top end of column 15 are a pair of arms 22. As 
best shown in FIG. 1A, each arm 22 is bent at a right angle forming 
parallel but horizontal arm extensions 22a. The extensions 22a are 
bifurcated at the distal ends thereof into a pair of spaced and parallel 
fingers 24 forming a yoke. The spacing between fingers 24 is sufficiently 
large to permit the opposite walls of dispensing apparatus 10 to slide 
therebetween and permitting the dispensing apparatus to be supported on 
fingers 24 by flange 21. The second flange 21a is spaced beneath flange 21 
a distance slightly greater than the vertical width of fingers 24. 
A major advantage of the combination is that the dispensing apparatus 10, 
and not bottle 14, is supported directly by stand 12. Because the bottle 
14 is held in a vertical position, not only saving space and more 
efficiently using the force of gravity for dispensing purposes, the prior 
art problem of torque exerted on the stand by the center of gravity of the 
bottle being displaced from the central axis is avoided. Stand 12 provides 
a stable base for one or more bottles 14 that is not easily tipped over by 
the user. A second pair of flanges or extensions 21a (shown in dashed 
lines) positioned below the flanges 21 may be provided to prevent a 
tilting of the bottle 14 and apparatus 10. 
While the figures herein disclose the use of a stand 12 in which the 
dispenser grasping yoke has a shape to accommodate a dispensing apparatus 
having a rectangular cross section, other yoke shapes may be employed as 
well depending upon the shape of the dispensing apparatus. For example, 
the cross section of the dispensing apparatus could be a circle in which 
the yoke would have a complimentary shape, i.e., a circle. Additionally, 
the stand could be provided with a single arm projecting forward and split 
into a pair of subarms, each bifurcated into a yoke configuration for 
supporting a dispensing apparatus. Additionally, the stand could be 
provided with a multiplicity of arms, each with a dispenser grasping yoke, 
thus accommodating a multiplicity of dispensers and associated bottles. 
The schematic of FIG. 2 illustrates the operative components of the 
dispensing apparatus of the present invention in a simplified perspective. 
The body 26 of the apparatus 10 defines a pair of spaced chambers 38 and 
40, preferably cylindrical, having respective longitudinal axis 38a and 
40a thereof arranged vertical with respect to the horizontal support 
surface when apparatus 10 is secured to stand 12 as shown in FIG. 1. 
Chamber 38 communicates at its upper end with mouth or opening 42 defined 
by collar 18 and receives liquid from beverage bottle 14. Chamber 40, 
however, is sealed about hollow tube 39 at its upper end, communicating 
solely through tube 39 with the ullage volume of bottle 14. At its lower 
end, chamber 38 communicates with passageway 44 leading to an open cavity 
48 defined by the extension of the sidewalls of the dispensing apparatus 
10. Similarly, chamber 40 is open at its lower end and communicates with 
passageway 46 that also leads to cavity 48. Passageway 44 has a vertical 
axis 42a which is essentially coaxial with axis 38a, this allowing the 
liquid to flow downwardly unimpeded from chamber 38 through passageway 44 
when open into cavity 48. Thus, passageway 38 and chamber 44 define a 
vertical channel extending from mouth or opening 42 to opening or cavity 
48. Positioned below opening 48 is a receptacle 51 for receiving the 
liquid passing through the vertical channel. From a review of FIGS. 1, 2, 
3, and 5, it may be seen that hollow tube 39 is eessentially parallel and 
closely positioned to vertical axis 42a. Thus, tube 39 extends straight 
through the liquid 16 when dispensing device 10 is being screwed to the 
mouth of the container 14 and thus there is little linear movement of tube 
39 relative to liquid 16 during the rotation motion involved when attaching 
dispensing device 10. 
It is important that the volumes of the chambers communicating with the 
container and ullage volume be maximized to the greatest extent possible 
within the constraints imposed by the dimensions of the body. Thus, 
chambers 38 and 40 collectively have volumes preferably greater than one 
half, to about two thirds, of the volume of the section of body 26 
defining the chambers. The large volumes of the chambers permit large 
volume flows of liquid and rapid expansion of gases accumulated in the 
ullage volume without a detrimental impact on the flow of the liquid and 
an undesirable liquid and gas expulsion noise along with attendant 
spraying effect. Selective release of the accumulated gas by careful 
opening of the valves is not necessary as is prevalent with prior art 
dispensing devices. 
Cavity 48 serves primarily to house the various operative components of the 
dispensing apparatus. Shaft 50 spans the width of cavity 48 and is 
rotatably journaled into and supported by opposing walls 52 and 54 of 
cavity 48. One end of shaft 50 extends through wall 52 and is connected to 
a manually operated handle 56. A cross bar 58 is secured substantially 
normal to shaft 50 at about the midpoint thereof and extends across the 
depth of cavity 48 where it is secured substantially normal at its other 
end to an arm 60 at about the midpoint thereof. 
A pair of tapered valve plugs or elements 62 and 64 are positioned 
respectively in the complimentarily tapered mouths of passageways 44 and 
46. Elements 62 and 64 are preferably made from elastomeric material 
compatible with the liquid contents of bottle 14 such as thermoplastic 
material acceptable for use in the food and beverage industry and suitable 
to seal the mouths of passageways 44 and 46 against fluid flow. Extending 
downwardly from elements 62 and 64 are respective valve stems 66 and 68 
coupled by respective slots 70 and 72 to the ends of arm 60. Slot 70 
vertically is larger than slot 72 providing stem 66 a lost motion coupling 
with arm 60. A spring 74 is connected to cross bar 58 and biases cross bar 
58 downwardly, thus via connecting arm 60 and valve stems 66 and 68, 
pulling valve elements 62 and 64 downward against the mouths of 
passageways 44 and 46. Passageways 44 and 46 are therefore normally sealed 
against fluid flow. 
Before handle 56 is turned, it may be seen from a brief review of FIGS. 2 
and 3 that arm 60 rests against the bottom of slots 70 and 72 due to the 
bias exerted by spring 74. When handle 56 is rotated clockwise, however, 
as shown by arrow 76 in FIGS. 1 and 2, arm 60 is rotated in the direction 
of the tops of slots 70 and 72. Because slot 70 is vertically longer than 
slot 72, arm 60 will first abut the top of slot 72, moving stem 68 and 
associated valve element 64 up and providing initial communication between 
the ullage volume and the atmosphere through now connecting chamber 40, 
passageway 46 and cavity 48. The pressure in the ullage volume will 
quickly equilibrate with atmospheric pressure before valve element 62 is 
raised. When valve element 62 is raised, liquid will flow directly 
downward through chamber 38 and passageway 44 container 51 unimpeded and 
without any change of direction of the liquid. The operating components 
offer very little resistance to the flow of the liquid and surprisingly 
create minimal foam when the liquid is carbonated. It should also be noted 
that the dispensing apparatus requires no spout to further direct the flow 
of liquid to a container. 
Once container 51 is filled to a desired level, handle 56 is released. 
Spring 74 under compression causes cross bar 58 to move downward, thus 
causing valve elements 62 and 64 to return to their sealed positions in 
the mouths of passageways 44 and 46. 
Referring now to FIG. 3 it may be seen that each valve element 62, 64 is 
provided with a respective valve guide 80 and 82 that has a diameter 
slightly less than the diameter of the respective chamber 38 and 40 in 
which it is positioned. When valve elements 62 and 64 are moved, guides 80 
and 82 prevent "off axis" motion of the valve elements. FIG. 7 shows a top 
elevation view of guide 80. It can be seen that the configuration will 
allow for the free flow of liquids through spaces 84 between the wall 38b 
of chamber 38 and guide 80. The structural relationship of guide 80 with 
respect to wall 38b is clearly shown in FIG. 2. 
FIG. 6 illustrates the spring biasing feature of the present invention. One 
end of helical spring 74 is secured within bore 86 in the top wall 88 of 
cavity 48 and the other end to cross bar 58. Thus, as seen in FIG. 3, when 
handle 56 is turned clockwise, cross bar 58 compresses spring 74 into bore 
86 where the stored potential energy is available to move cross bar 58 
back once handle 56 is released. It should be understood that the type of 
spring may be varied as desired. For example a leaf spring could be 
employed requiring little structural modification. Additionally, the 
spring could be mounted so as to create the bias through extension of the 
spring rather than through compression. 
FIG. 8 illustrates an alternate structure of the present invention in which 
the ullage equilibration is accomplished through the use of a separate hole 
to the atmosphere into cavity 48. Passageway 46 is sealed from cavity 48 by 
upper wall 88 of cavity 48. As illustrated, valve stem 68 slides through 
upper wall 88. However, a small hole 90 permits passageway 46 to 
communicate with the atmosphere. When valve element 64 is raised, ullage 
volume can effectively equilibrate as before. An advantage of this 
structure is that the valve guide for element is not needed since stem 68 
is effectively constrained for vertical movement only by wall 88. 
From the above it can now be appreciated that dispensing apparatus and 
stand therefore of the present invention provide considerable advantages. 
First, because the liquid flows vertically downwardly essentially 
unimpeded from bottle to awaiting glass, little foam is generated in 
contrast to many prior art devices. Additionally, the operating components 
housed within open cavity 48 are easily reachable and cleanable. Finally, 
none of the operating components require sealing against channeling of the 
liquid in undesirable directions since all are housed within an open cavity 
and do not extend through walls containing a flow of liquid. 
In this disclosure, there is shown and described only the preferred 
embodiment of the invention, but it is understood that the invention is 
capable of changes and modifications within the scope of the inventive 
concept as expressed herein.
