Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to beverage dispensing nozzles and, more particularly, but not by way of limitation, to a beverage dispensing nozzle for dispensing multiple flavored drinks from a single nozzle without intermingling flavors.




2. Description of the Related Art




Due to increases in both the number of customers served and the volume of drinks dispensed by the food and drink service industry and counter space being at a premium, standard drink dispensing nozzles fail to meet customer demand. In order to reduce space requirements and also for aesthetic reasons, it is desirable to dispense multiple flavors of drinks from a single nozzle.




In dispensing drinks from a nozzle, it is essential that the flavored syrup be intimately mixed with a mixing fluid, such as carbonated or plain water, so that the resulting drink is of uniform consistency. When the mixing fluid is carbonated water, it is essential that the carbonated water and syrup be mixed in such a manner that the carbon dioxide does not excessively escape and produce undesirable foaming.




One major problem encountered with multiple flavor nozzles is syrup carryover. It is very difficult to completely remove the residual syrup from a previously dispensed drink to avoid carryover into a subsequent, different flavored drink. This carryover causes problems with the flavor, the color, and the smell of dispensed drinks. Even small amounts of carryover syrup which cause only minor problems with odor and taste have a significant effect on the color of clear drinks, which is undesirable.




Another problem that must be addressed is proper mixing of the mixing fluid, such as carbonated or plain water, and syrup. To insure proper mixing, it is necessary to expose the maximum surface area of the syrup to the mixing fluid. If the mixing is to occur outside the nozzle, it is important that the momentum of the syrup stream be substantially equal to or less than the momentum of the mixing fluid stream.




Excessive foaming is another problem when the mixing fluid is carbonated water. To prevent excessive foaming, the carbonated water, which enters the nozzle at a high pressure, must be gently reduced to atmospheric pressure so that a minimum of carbon dioxide will escape solution. At high flow rates, out-gassing of carbon dioxide is particularly troublesome. Consequently, as the carbonated water releases carbon dioxide in both the nozzle and the cup, the released carbon dioxide escaping solution causes excessive foaming of the dispensed beverage. That excessive foaming creates a poor product because the drink is generally “flat”.




Prior attempts to solve the aforementioned problems with multiple flavor nozzles have not been successful. In most instances, as in U.S. Pat. No. 4,928,854, which issued on May 29, 1990, to McCann, the syrup is delivered to the nozzle exit through a separate tubular conduit for each flavor. The syrup flows through a plurality of separate conduits to a discharge opening into a water channel for delivery to the exit end of the nozzle. The total surface area of syrup presented for contact with the mixing fluid is relatively small; thus proper mixing is difficult. The configuration also makes it difficult to eliminate syrup carryover.




SUMMARY OF THE INVENTION




In accordance with the present invention, a beverage dispensing nozzle, includes a cap member having first, second, and third beverage syrup inlet ports coupled to first, second, and third beverage syrup sources and a mixing fluid inlet port coupled to a mixing fluid source. A first annulus, a second annulus, and a third annulus are each coupled with the cap member for discharging from the beverage dispensing nozzle via discharge channels a beverage syrup delivered from a respective first, second, and third beverage syrup inlet port. An outer housing is coupled to the cap member and defines a mixing fluid channel with the first annulus for discharging from the beverage dispensing nozzle a mixing fluid delivered from the mixing fluid inlet port, which is mixed with exiting beverage syrup.




The first annulus, the second annulus, and the third annulus each include a groove therein that receives beverage syrup from a respective first, second, and third beverage syrup inlet port and delivers the beverage syrup to the discharge channels. The cap member comprises a first, second, and third beverage syrup outlet port connected with a respective first, second, and third beverage syrup inlet port and a raised portion, wherein each raised portion fits within a respective groove to couple the first annulus, the second annulus, and the third annulus to the cap member and to communicate beverage syrup to the first annulus, the second annulus, and the third annulus. The cap member further includes a plurality of mixing fluid outlet channels connected to the mixing fluid inlet port and communicating with the mixing fluid channel for circumferentially delivering mixing fluid into the mixing fluid channel.




It is, therefore, an object of the present invention to provide a beverage dispensing nozzle that dispenses a beverage syrup and mixing fluid at a high volume flow to form a dispensed beverage drink.




It is another object of the present invention to provide a beverage dispensing nozzle that eliminates stratification between the beverage syrup and mixing fluid.




It is further object of the present invention to provide a beverage dispensing nozzle that is capable of dispensing multiple flavors while preventing carryover between different flavored syrups.




Still other objects, features, and advantages of the present invention will become evident to those skilled in the art in light of the following.

10


, thereby providing a maximum surface area for contact with mixing fluid also exiting from the beverage dispensing nozzle


10


. Although the preferred embodiment discloses annuluses


17


-


19


, one of ordinary skill in the art will recognize that alternative shapes, such as elliptical or polygonal, may be utilized.




The cap member


11


includes beverage syrup inlet ports


21


-


23


that communicate with a respective beverage syrup outlet port


24


-


26


via a respective connecting conduit


37


-


39


through the cap member


11


(refer to

FIGS. 1

,


2


, and


7


-


9


). The cap member


11


includes protrusion


35


to aid in the securing of the inner housing


16


to the cap member


11


. The beverage syrup outlet ports


24


-


26


snap fit within a respective cavity


41


-


42


of the inner housing to secure the inner housing


16


to the cap member


11


. The gaskets


13


-


15


fit around a respective beverage syrup outlet port


24


-


26


to provide a fluid seal and to assist in the securing of the inner housing


16


to the cap member


11


. In addition, the securing member of the third or inner annulus


18


extending through the opening


44


of the inner housing


16

35


of the cap member


11


to aid in the securing of the inner housing

. With the inner housing


16


secured to the cap member


11


, a beverage syrup path involving the beverage syrup inlet port


21


; the conduit


37


; the beverage syrup outlet port


24


; the cavity


41


; the conduit


45


; and the annular channel


58


, which includes the discharge channels


59


, is created. A beverage syrup path involving the beverage syrup inlet port


22


; the conduit


38


; the beverage syrup outlet port


25

; the beverage syrup outlet port


26


; the cavity


43


; the conduit


47


; the annular channel


64


, which includes the discharge channels


63


; are also created.




The cap member


11


includes a mixing fluid inlet port


27


that communicates with mixing fluid outlet channels


66


-


71


via a connecting conduit


28


through the cap member


11


(refer to

FIGS. 1-3

and


6


). The mixing fluid outlet channels


66


-


71


in this first embodiment are uniformly spaced within the cap member


11


and communicate with an annular cavity


36


defined by a portion of the cap member


11


to deliver mixing fluid along the entire circumference of the annular cavity


36


. In this first embodiment, the preferred mixing fluid is carbonated water, which forms a carbonated beverage drink when combined with a beverage syrup. Nevertheless, one of ordinary skill in the art will recognize that other mixing fluids, such as plain water may be used. Furthermore, although the preferred embodiment discloses the formation of a beverage from a beverage syrup and a mixing fluid, such as carbonated or plain water, one of ordinary skill in the art will recognize that a mixing fluid, such as carbonated or plain water, may be dispensed individually from a beverage path as described above instead of a beverage syrup.




The cap member


20


includes dog ears


29


and


30


that permit the connection of the cap member


11


to a standard dispensing valve using suitable and well known means. Each of the beverage syrup inlet ports


21


-


23


receives a beverage syrup conduit to supply the beverage dispensing nozzle


10


with a beverage syrup. Similarly, the mixing fluid inlet port


27


receives a mixing fluid conduit to supply the beverage dispensing nozzle


10


with a mixing fluid. A fastening clip secured to each of bosses


31


-


33


, utilizing a screw or other suitable means, maintains the beverage syrup conduits coupled with a respective beverage syrup inlet port


21


-


23


and the mixing fluid conduit coupled with the mixing fluid inlet port


27


. The cap member


11


includes a groove


34


for receiving the o-ring


12


therein.




The outer housing


20


snap fits over the cap member


11


, including the o-ring


12


which provides a fluid seal and assists in the securing of the outer housing


16


to the cap member


11


. The outer housing


20


includes flanges


74


and


75


and tabs


76


and


77


to mount the outer housing


20


to a standard dispensing valve in well known manner. The outer housing


20


further includes an inwardly extending lip portion


73


at its exit end. The interior wall of the outer housing


20


in combination with the portion of the cap member


11


defining the annular cavity


36


and the exterior wall of the inner housing define an annular channel


72


. With the outer housing


20


secured to the cap member


11


, a mixing fluid path involving the mixing fluid inlet port


27


, the conduit


28


, the mixing fluid outlet channels


66


-


71


, and the annular channel


72


is created. Although the preferred embodiment contemplates the dispensing of a mixing fluid, such as carbonated or plain water, in combination with a beverage syrup, one of ordinary skill in the art will recognize that the mixing fluid may be dispensed separately to provide the mixing fluid by itself.




In operation, mixing fluid enters the beverage dispensing nozzle


10


through the mixing fluid inlet port


27


and travels through the conduit


28


to the mixing fluid outlet channels


66


-


71


for delivery into the annular cavity


36


(refer to FIGS.


7


-


9


). The annular cavity


36


receives a large volume of mixing fluid to insure the annular channel


72


remains full for uniform flow around the annular channel


72


as the mixing fluid flows downwardly through the annular channel


72


to the discharge end of the annular channel


72


. In the preferred embodiments, the discharge end of the annular channel


72


may be partially closed to increase the momentum of the mixing fluid exiting the annular channel


72


to maintain a uniform distribution of mixing fluid exiting around the entire circumference of the annular channel


72


. The inwardly extending lip portion


73


of the outer housing


20


directs the mixing fluid inwardly toward a beverage syrup stream exiting from one of discharge members


53


,


57


, and


62


. The inward directing of the mixing fluid provides for intimate mixing as well as a means for washing the discharge end of the annular channel


72


to prevent syrup carryover.




The beverage syrup inlet ports


21


-


23


each receive a different flavor of beverage syrup, which is delivered through a conduit by a beverage syrup source (not shown). Each beverage syrup travels through its particular flow path for discharge from the beverage dispensing nozzle


10


as previously described (refer to FIGS.


7


-


9


). Illustratively, a beverage syrup delivered to the beverage syrup inlet port


21


flows through the conduit


37


, the beverage syrup outlet port


24


, the cavity


41


, the conduit


45


, the annular channel


58


, and the discharge channels


59


prior to discharge from the beverage dispensing nozzle


10


. The annular channels


54


,


58


, and


64


provide a large volume of beverage syrup around each of a respective first or outer, second or intermediate, and third or inner annulus for discharge through one of the discharge members


53


,


57


, and


62


. The discharge members


53


,


57


, and


62


restrict the flow of beverage syrup to insure uniform distribution of the beverage syrup as it exits from the beverage dispensing nozzle


10


, thus insuring a maximum surface area for contact with the mixing fluid exiting from the annular channel


72


. Although only one beverage syrup is typically dispensed at a time, it should be understood that more than one beverage syrup may be discharged from the beverage dispensing nozzle


10


at a time to provide a mix of flavors.




An important feature of the beverage dispensing nozzle


10


is the annular discharge of a beverage syrup, whereby the annularly discharged mixing fluid contacts the beverage syrup in mid-air below the dispensing nozzle


10


. The annular discharge shape of the beverage syrup and the mixing fluid significantly increases the contact surface area between the two streams, resulting in more effective mixing. Furthermore, the mixture of the beverage syrup and the mixing fluid outside the beverage dispensing nozzle


10


eliminates the sanitary considerations that occur with a mixing chamber interior to the nozzle; namely, the unsanitary build up of bacteria on the interior of the mixing chamber, which is exacerbated due to the stickiness of the beverage syrup. Although three separate beverage syrup sources with three annuluses have been described, one of ordinary skill in the art will recognize that any number of beverage syrup sources and annuluses could be provided, including a single beverage syrup source and annulus. In addition, the single stream of mixing fluid exiting from the annular channel


72


may be separated into two or more streams.




As illustrated in

FIGS. 10-12

, a second embodiment of the beverage dispensing nozzle


100


is virtually identical in configuration and operation to the first embodiment of the beverage dispensing nozzle


10


. Consequently, components for the beverage dispensing nozzle


100


of like configuration and operation to components of the beverage dispensing nozzle


10


have been referenced with like numerals. The beverage dispensing nozzle


100


is configured and operates as the beverage dispensing nozzle


10


, except the beverage dispensing nozzle


100


includes a conduit


101


coupled to the conduit


28


to communicate mixing fluid into a center conduit


102


of the third or inner annulus


19


. In addition, the third or inner annulus


18


includes an outlet


103


for discharging the mixing fluid interior to a discharged beverage syrup stream. The conduit


28


therefore not only delivers mixing fluid to the mixing fluid outlet channels


66


-


71


but also to the conduit


101


for delivery to the center conduit


102


. The center conduit


102


delivers the mixing fluid through the center of the beverage dispensing nozzle


100


, where it exits inside a beverage syrup stream to enhance mixing of the mixing fluid and beverage syrup. The beverage dispensing nozzle


100


is particularly desirable for use in dispensing single flavor beverage drinks and for use with large volume beverage dispensing nozzles. A diffuser


104


may be positioned within the conduit


101


to direct the mixing fluid onto the sides of the center conduit


102


to prevent a single stream exiting the outlet


103


, thereby improving surface contact between the mixing fluid and beverage syrup.




As illustrated in

FIG. 13

, a third embodiment of the beverage dispensing nozzle


200


is virtually identical in configuration and operation to the first embodiment of the beverage dispensing nozzle


10


. Consequently, components for the beverage dispensing nozzle


200


of like configuration and operation to components of the beverage dispensing nozzle


10


have been referenced with like numerals. The beverage dispensing nozzle


200


is configured and operates as the beverage dispensing nozzle


10


, except, in the beverage dispensing nozzle


200


, the outlet end of the first or outer annulus


17


includes a conical cut-out portion


201


, the outlet end of the second or intermediate annulus


18


includes a conical cut-out portion


202


, and the outlet end of the third or inner annulus


19


includes a conical cut-out portion


203


. When the first or outer annulus


17


, the second or intermediate annulus


18


, and the third or inner annulus


19


are secured within the inner housing


16


, the conical cut-out portions


201


,


202


, and


203


define a reverse conical beverage syrup outlet


204


that aids in preventing beverage syrup carryover by facilitating the formation of a low pressure region at the beverage syrup outlet


204


. During the dispensing of a beverage syrup and a mixing fluid to form a beverage, the low pressure region permits the flow of mixing fluid over the beverage syrup outlet


204


, thereby washing the beverage syrup outlet


204


to remove any carryover beverage syrup.




As illustrated in

FIG. 14

, a fourth embodiment of the beverage dispensing nozzle


300


is virtually identical in configuration and operation to the first embodiment of the beverage dispensing nozzle


10


. Consequently, components for the beverage dispensing nozzle


300


of like configuration and operation to components of the beverage dispensing nozzle


10


have been referenced with like numerals. The beverage dispensing nozzle


300


is configured and operates as the beverage dispensing nozzle


10


, except, in the beverage dispensing nozzle


300


, the outlet end of the first or outer annulus


17


includes a concave cut-out portion


301


, the outlet end of the second or intermediate annulus


18


includes a concave cut-out portion


302


, and the outlet end of the third or inner annulus


19


includes a concave cut-out portion


303


. When the first or outer annulus


17


, the second or intermediate annulus


18


, and the third or inner annulus


19


are secured within the inner housing


16


, the concave cut-out portions


301


,


302


, and


303


define a concave beverage syrup nozzle outlet


304


that aids in preventing beverage syrup carryover by facilitating the formation of a low pressure region at the beverage syrup outlet


304


. During the dispensing of a beverage syrup and a mixing fluid to form a beverage, the low pressure region permits the flow of mixing fluid over the beverage syrup outlet


304


, thereby washing the beverage syrup outlet


304


to remove any carryover beverage syrup.




As illustrated in

FIG. 15

, a fifth embodiment of the beverage dispensing nozzle


400

916


; a respective connecting conduit; the beverage syrup outlet port


919


; a respective cavity defined by the groove


911


; and the discharge channels

; are also created.




The cap member


901


includes a mixing fluid inlet port


923


that communicates with mixing fluid outlet channels


924


via a connecting conduit through the cap member


901


. The mixing fluid outlet channels


924


in this tenth embodiment are uniformly spaced within the cap member


901


and communicate with an annular cavity


925


defined by a portion of the cap member


901


to deliver mixing fluid along the entire circumference of the annular cavity


925


. In this tenth embodiment, the preferred mixing fluid is carbonated water, which forms a carbonated beverage drink when combined with a beverage syrup. Nevertheless, one of ordinary skill in the art will recognize that other mixing fluids, such as plain water may be used. Furthermore, although the preferred embodiment discloses the formation of a beverage from a beverage syrup and a mixing fluid, such as carbonated or plain water, one of ordinary skill in the art will recognize that a mixing fluid, such as carbonated or plain water, may be dispensed individually from a beverage path as described above instead of a beverage syrup.




The cap member


901


includes dog ears


926


-


928


that permit the connection of the cap member


901


to a standard dispensing valve using suitable and well known means. Each of the beverage syrup inlet ports


914


-


916


receives a beverage syrup conduit to supply the beverage dispensing nozzle


900


with a beverage syrup. Similarly, the mixing fluid inlet port


923


receives a mixing fluid conduit to supply the beverage dispensing nozzle


900


with a mixing fluid. A fastening clip secured to each of bosses


929


-


931


, utilizing a screw or other suitable means, maintains the beverage syrup conduits coupled with a respective beverage syrup inlet port


914


-


916


and the mixing fluid conduit coupled with the mixing fluid inlet port


923


. The cap member


901


includes a groove


932


for receiving the o-ring


902


therein.




The outer housing


906


fits over the cap member


901


, including the o-ring


902


which provides a fluid seal and assists in the securing of the outer housing


906


to the cap member


901


, and is held in place via tabs


933


-


935


. The outer housing


906


includes flange


936


that aids in mounting the outer housing


906


to a dispensing valve in well-known manner. The outer housing


906


further includes an inwardly extending lip portion


937


and slots


938


at its exit end. The interior wall of the outer housing


906


in combination with the portion of the cap member


901


defining the annular cavity


36


and the exterior wall of the first or inner annulus


903


define an annular channel. With the outer housing


906


secured to the cap member


901


, a mixing fluid path involving the mixing fluid inlet port


923


, the connecting conduit, the mixing fluid outlet channels


924


, and the annular channel is created. Although the preferred embodiment contemplates the dispensing of a mixing fluid, such as carbonated or plain water, in combination with a beverage syrup, one of ordinary skill in the art will recognize that the mixing fluid may be dispensed separately to provide the mixing fluid by itself.




In operation, mixing fluid enters the beverage dispensing nozzle


900


through the mixing fluid inlet port


923


and travels through the connecting conduit to the mixing fluid outlet channels


924


for delivery into the annular cavity


925


. The annular cavity


925


receives a large volume of mixing fluid to insure the annular channel remains full for uniform flow around the annular channel as the mixing fluid flows downwardly through the annular channel to the discharge end of the annular channel. In the tenth embodiment, the discharge end of the annular channel may be partially closed to increase the momentum of the mixing fluid exiting the annular channel to maintain a uniform distribution of mixing fluid exiting around the entire circumference of the annular channel. The inwardly extending lip portion


937


of the outer housing


906


directs the mixing fluid inwardly toward a beverage syrup stream exiting from one of the first or outer annulus


903


, the second or intermediate annulus


904


, and the third or inner annulus


905


. The inward directing of the mixing fluid provides for intimate mixing as well as a means for washing the discharge end of the annular channel to prevent syrup carryover.




Furthermore, the slots


938


aid in the prevention of syrup carryover by preventing fluid bridging between the first or outer annulus


903


and the outer housing


906


, which could result in beverage syrup being drawn from one of the first or outer annulus


903


, the second or intermediate annulus


904


, and the third or inner annulus


905


. The slots


938


interrupt the surface of the outer housing


906


so that, upon the end of a dispense, any remaining mixing fluid accumulates in a drop on the surface between each individual slot


938


. The drop falls from the outer housing


906


due to gravity, thereby preventing fluid bridging between the first or outer annulus


903


and the outer housing


906


.




The beverage syrup inlet ports


914


-


916


each receive a different flavor of beverage syrup, which is delivered through a conduit by a beverage syrup source (not shown). Each beverage syrup travels through its particular flow path for discharge from the beverage dispensing nozzle


900


as previously described. Illustratively, a beverage syrup delivered to the beverage syrup inlet port


914


flows through the connecting conduit, the beverage syrup outlet port


917


, the cavity defined by the groove


907


, and the discharge channels


908


prior to discharge from the beverage dispensing nozzle


900


. The discharge channels


908


,


910


, and


912


provide beverage syrup around each of a respective first or outer, second or intermediate, and third or inner annulus for discharge from the beverage dispensing nozzle


900


. The discharge channels


908


,


910


, and


912


insure uniform distribution of the beverage syrup as it exits from the beverage dispensing nozzle


900


, thus insuring a maximum surface area for contact with the mixing fluid exiting from the annular channel. Although only one beverage syrup is typically dispensed at a time, it should be understood that more than one beverage syrup may be discharged from the beverage dispensing nozzle


900


at a time to provide a mix of flavors.




An important feature of the beverage dispensing nozzle


900


is the annular discharge of a beverage syrup, whereby the annularly discharged mixing fluid contacts the beverage syrup in mid-air below the dispensing nozzle


900


. The annular discharge shape of the beverage syrup and the mixing fluid significantly increases the contact surface area between the two streams, resulting in more effective mixing. Furthermore, the mixture of the beverage syrup and the mixing fluid outside the beverage dispensing nozzle


900


eliminates the sanitary considerations that occur with a mixing chamber interior to the nozzle; namely, the unsanitary build up of bacteria on the interior of the mixing chamber, which is exacerbated due to the stickiness of the beverage syrup. Although three separate beverage syrup sources with three annuluses have been described, one of ordinary skill in the art will recognize that any number of beverage syrup sources and annuluses could be provided, including a single beverage syrup source and annulus. In addition, the single stream of mixing fluid exiting from the annular channel may be separated into two or more streams.




Although the present invention has been described in terms of the foregoing embodiment, such description has been for exemplary purposes only and, as will be apparent to one of ordinary skill in the art, many alternatives, equivalents, and variations of varying degrees will fall within the scope of the present invention. That scope, accordingly, is not to be limited in any respect by the foregoing description; rather, it is defined only by the claims that follow.
