     FIELD OF THE INVENTION 
     The present invention relates to beverage dispensers, and in particular to the cleaning of beverage dispensers and to the providing of a clean environment for a beverage dispenser. Specifically, a method and apparatus are disclosed for cleaning a dispenser which dispenses beverages and for maintaining the beverage dispenser in a clean environment. 
     BACKGROUND OF THE INVENTION 
     Restaurants, bars, and other types of food establishments use a dispenser in order to dispense beverages.  FIG. 1  illustrates an exemplary prior art device that is used to dispense beverages and that is identified by several different names including a bar dispenser, a bar gun, and a soda gun. Dispenser  100  includes housing  104  with several pushbuttons  108  mounted thereon. Depending upon which pushbutton  108  is depressed, one of several beverages are dispensed (into a glass for example) via nozzle  106 . 
     Dispenser  100  is coupled to a plurality of different beverages (or beverage ingredients) via inlet hose  102 . Within inlet hose  102 , a plurality of tubes (not shown) receive beverages (or beverage ingredients) from different sources. For example, one of the tubes within inlet hose  102  may be connected to a water source so that water can be dispensed from dispenser  100 . Another tube within inlet hose  102  may be connected to a source of carbonated water. Other tubes within inlet hose  102  may be connected to containers storing concentrated beverage ingredients (e.g. concentrated soda flavorings). Dispenser  100  may mix one of the beverage ingredients with carbonated water to produce various types of flavored sodas (for example). 
     Pushbuttons  108  thus each correspond to various beverages such as water, carbonated water, or various flavored sodas. If pushbutton  108  corresponding to water or carbonated water is depressed, then water or carbonated water is dispensed through nozzle  106 . If pushbutton  108  corresponding to a flavored soda is depressed, then concentrated soda flavoring and carbonated water are mixed within dispenser  100  and dispensed through nozzle  106 . An exemplary dispenser is manufactured by Wunder-bar. A further exemplary dispenser is disclosed in Schroeder, U.S. Pat. No. 7,658,006, which is hereby incorporated by reference in its entirety. 
     At least some of the concentrated soda flavorings received by dispenser  100  include corn syrup as a sweetener. Thus, as various flavored sodas and/or other beverages are dispensed from nozzle  106 , a residue which may include corn syrup remains on various surfaces of nozzle  106 . Over time, the residue builds and nozzle  106  becomes unsanitary. 
     Also, the soda flavorings (and/or residue from the soda flavorings or other beverages) accumulate in a drain that is used to catch soda flavorings that are dispensed by dispenser  100  and that do not enter a glass or cup. For example, when dispenser  100  is resting on a holster when not in use, fluids will typically drip out of nozzle  106  and will flow down a drain. As the flavorings and/or residue flow down the drain, they will sometimes remain on drain surfaces. Consequently, fruit flies are attracted to the drain, multiply, and create an unhealthy environment. If not addressed, the fruit flies will fly out of the drain and into the area where the nozzle rests when not in use (e.g. in a holster). This is undesirable for a restaurant and/or bar venue. The resulting multitude of fruit flies is unclean, unhealthy, and is significantly disliked by both employees and customers. Presence of fruit flies in a bar and/or restaurant may result in reduced customers, reduced profits, and bad social media reviews. 
     Restaurants, bars, and other types of food establishments use a dispenser in order to dispense beverages.  FIG. 19  illustrates an exemplary prior art device which is used to dispense beverages and which is identified by several different names including a beverage dispenser or a soda dispenser. Dispenser unit  50  includes a plurality of dispensers  100 . Each dispenser  100  dispenses a different beverage, such as (for example) water, soda and/or juice. 
     Dispenser unit  50  is coupled to a plurality of different beverages (or beverage ingredients) via respective hoses. For example, one hose may be connected to a water source so that one dispenser  1100  can dispense water. Another hose may be connected to a source of carbonated water. Other hoses may be connected to containers storing concentrated beverage ingredients (e.g. concentrated soda flavorings). Each dispenser  100  may mix one of the beverage ingredients with carbonated water to produce various types of flavored sodas (for example). 
     Each dispenser  1100  may correspond to various beverages such as water, carbonated water, or various flavored sodas. Each dispenser may be labeled with the respective beverage that is dispenses. Each dispenser may include an actuator arm  1107  that controls a respective actuator. When an actuator arm  1107  is pushed backwards (by being pushed, for example, with a cup or glass), the beverage corresponding to the pushed actuator arm is dispensed. Each dispenser includes a respective nozzle from which the dispenser&#39;s respective beverage is dispensed. Pushing the actuator arm  1107  on a dispenser causes a beverage to be dispensed from that dispenser&#39;s respective nozzle  1106 . If actuator arm  1107  corresponding to water or carbonated water is depressed, then water or carbonated water is dispensed through nozzle  1106 . If actuator arm  1107  corresponding to a flavored soda is depressed, then concentrated soda flavoring and carbonated water are mixed within dispenser  1100  and dispensed through nozzle  1106 . An exemplary dispenser is disclosed in U.S. Pat. No. 5,381,926, which is hereby incorporated by reference in its entirety. 
     Other prior art beverage dispensers use push buttons instead of actuator arm in order to dispense beverages. A cup is placed under nozzle  1106 , the push button is pushed, and the beverage is dispensed into the cup. 
     At least some of the concentrated soda flavorings received by dispenser  1100  include corn syrup as a sweetener. Thus, as various flavored sodas are dispensed from nozzle  1106 , a residue which includes corn syrup remains on various surfaces of nozzle  1106 . Over time, the residue builds and nozzle  1106  becomes unsanitary. 
     SUMMARY OF THE INVENTION 
     A method of delivering insecticide comprises the steps of providing an insecticide in a container, allowing the insecticide to flow out of the container, and allowing the insecticide to flow into a drain beginning downstream of an opening in said drain. 
     A method and apparatus cleans a plurality of beverage dispensers which are located within a dispenser unit. A plurality of arms are rotatable with reference to beverage dispensers, respectively, so that a cleaning nozzle attached to each arm is situated under a respective dispenser nozzle. The cleaning nozzles are oriented to spray cleaning solution towards respective dispenser nozzles. At least one fluid valve and/or pump alternatively permits and blocks a cleaning solution to flow to the nozzles, respectively. A power supply provides flow signals to the at least one fluid valve and/or pump, respectively, wherein the valve(s) and/or pump transitions between permitting and not permitting flow of cleaning solution responsive to transitioning of the flow signals, respectively. A transmitter signals the power supply to transition the flow signals to cause the fluid valve(s) and/or pump to permit the cleaning solution to flow to the cleaning nozzles.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 2A  illustrates a further exemplary embodiment of the present invention. 
     As shown in  FIG. 2A  and  FIG. 2B , and as previously described, dispenser  100  has been stored on top of (and partially within) holster  200 . Dispenser  100  includes pushbuttons  108  that may be depressed for dispensing different types of beverages. The various types of beverages flow into dispenser  100  via inlet hose  102 . Holster  200  includes back ledge  210  which may be mounted, for example, to the underside of a countertop such as a bar countertop. 
     During use, and as previously described, beverages flow out of dispenser  100  (and are thus discharged through nozzle  106 ) based on which pushbutton  108  is depressed. Some beverages, however, flow down drain  310  when dispenser  100  is inserted into holster  200  after a beverage has been dispensed (and while discharge from nozzle  106  is still occurring). After a period of time, small quantities of the beverages that have been dispensed from dispenser  100  will accumulate within drain  310 . The beverages that have been dispensed from dispenser  100  typically include corn syrup. Various types of insects, such as fruit flies, are often attracted to corn syrup. Thus, fruit flies will typically accumulate and breed within drain  310 . 
     As previously described, as the fruit flies continue to breed and accumulate within drain  310 , fruit flies will eventually fly out of drain  310  and to the location where drain  310  is connected to holster  200 . The fruit flies will fly out of holster  200  and will begin to fly around the bar and/or restaurant area where dispenser  100  is being used. Such an accumulation of fruit flies is disturbing to both customers and employees. Customers that see fruit flies in a bar and/or restaurant establishment may not return in the future. Thus, the accumulation of fruit flies in the area where dispenser  100  is being used is undesirable. 
     In accordance with an exemplary embodiment of the present invention, container  302  is included. Container  302  includes a chemical or solution  312  that eliminates insects such as fruit flies. Solution  312  may therefore be what is known as an insecticide, namely a substance that kills insects. A small opening may be found at the bottom of container  302  so that solution  312  that is stored in container  302  and that eliminates fruit flies slowly enters drain  310 . As shown, support member  306  is coupled to holster  200 . Container  302  sits within support members  303 ,  306  with the opening of container  302  facing downwards, in the direction of gravity. Solution  312  slowly flows out of container  302 , through drain tube  314 , and into drain  310  at secondary drain opening  316 . While beverages dispensed from dispenser  100  (or having a residual amount dripping out of dispenser  100 ) first enter drain  310  at the point where holster outlet  204  meets drain  310 , solution  312  is first introduced into drain  310  at a location past the point where holster outlet  204  and drain  310  meet. That location past the point where holster outlet  204  and drain  310  meet is considered to be “downstream” from holster outlet  204 . In particular, residue and/or waste moves downstream as follows through drain  310 . Downstream flow through drain  310  normally occurs under the force of gravity, although it may be accomplished with a pump (or suction) as well. Thus, solution  312  first enters drain  310  downstream of where fluid or residue exiting nozzle  106  first enters drain  310 . As solution  312  slowly drips into drain  310 , any fruit flies resident within drain  310  are eliminated. 
     Depending on the composition of solution  312 , solution  312  may be used against insect eggs and larvae. With regard to fruit flies, solution  312  may be used against, for example, fruit fly eggs. 
     In an exemplary embodiment of the present invention, solution  312  is Permethrin. Permethrin is one example of the insecticide that may be used for solution  312 . It is understood, however, that other insecticides may be used in place of, or in addition to permethrin. Exemplary other insecticides that may be used within solution  312  include, for example, Methoprene, Pyrethrin, and Pyrethrum. Again, these are merely exemplary as other insecticides may also be used for solution  312 . 
     Solution  312  slowly drips out of container  302 . Thus, at regular intervals (for example), container  302  is regularly refilled with insecticide so that elimination of fruit flies, and other insects, in drain  310  may occur on a continuous basis. 
     In one exemplary embodiment of the present invention, solution  312  is poured into container  302 , and from there, solution  312  enter drain  310 . Container  302  can be refilled at any desired time, including when container  302  is empty. In particular, container  302  can be removed from support members  303 ,  306 , refilled with solution  312 , and then reinserted into position by support members  303 ,  306 . There are various ways to determine when container  302  may be refilled. In one embodiment, container  302  is refilled on a regular basis (e.g. daily, weekly, etc.). In another embodiment, container  302  is refilled when the level of solution  312  in container  302  has dropped below a certain level (which can be observed through visual inspection or measured using, for example, an electronic sensor). In a further exemplary embodiment of the present invention, an opening is accessible to the interior of container  302  so that container  302  can be filled with solution  312  while remaining in place by support members  303 ,  306 . 
       FIG. 2A  illustrates container  302  attached to the underside of holster  200 . In the exemplary embodiment shown in  FIG. 2A , solution  312  flows into drain  310  via drain tube  314 . Furthermore, in accordance with a further exemplary embodiment of the present invention, backflow prevention device  311  is included. Backflow prevention device  311  prevent solution  312  (which may be an insecticide) from splashing upwards and entering holster interior  240 . 
     In the exemplary embodiment shown in  FIG. 2A  and Fig. to be, cleaning solution flows through fluid to  313  and towards nozzle  106 . In this manner, nozzle  106  is cleaned. The cleaning of nozzle  106  is further described in U.S. patent application Ser. No. 14/935,664 which is hereby Incorporated by reference in its entirety. Thus, cleaning solution flows through fluid tube  313 , and into holster interior  240  via holster inlet  206 . After reaching holster interior  240 , the cleaning solution flows towards nozzle  106  through various methods and/or structures. One exemplary structure is described in U.S. application Ser. No. 14/935,664. Another exemplary structure is described below. 
     As further illustrated in  FIG. 2B , fluid tube  313  is located below container  302 . In  FIG. 2B , it can be seen that solution  312  flows into drain  310  via drain tube  314 . 
       FIG. 3A  illustrates a further exemplary embodiment of the present invention. In  FIG. 3A , and contrast with  FIG. 2A , fluid tube  313  is located on a side of container  302 . This exemplary embodiment enables container  302  to have more vertical depth than the exemplary embodiment illustrated in  FIG. 2A . However, in some situations, the configuration shown in  FIG. 2A  may be preferred. As shown in  FIG. 3A , support member  306  is included for keeping container  302  in place. Furthermore, in the embodiment shown in  FIG. 3A , as container  302  extends all the way down to drain  310 , drain tube  314  may be shortened or possibly eliminated. Also, as shown in  FIG. 3A , optional backflow prevention device  311  may be included similarly as is done in the embodiment illustrated in  FIG. 2A . 
     In  FIG. 3A , container  302  extends all the way down to drain  310 . It is understood, however, that container  302  may have various lengths, widths, and shapes. Container  302  may extend only part way down towards drain  310 . Alternately, container  302  may have a height that does not extend all the way up to back ledge  210 . 
       FIG. 3B  illustrates the exemplary embodiment shown in  FIG. 3A  but from a perspective view. As is again illustrated in  FIG. 3B , fluid tube  313  may extend along the side of container  302 . 
       FIG. 3C  is a top view of holster  200  which again illustrates that fluid tube  313  may be situated along the side of container  302 . 
     Thus, in accordance with the embodiments described above, fluid tube  313  may be situated below container  302 . In a further exemplary embodiment, fluid tube  313  may be situated on either side of container  302 . In yet a further exemplary embodiment of the present invention, fluid tube  313  may be situated above container  302 . 
     In the exemplary embodiments described above, solution  312  may flow into drain  310  via gravity. It is understood, however, that solution  312  may be introduced into drain  310  through the use of other mechanisms, such as a pump. An exemplary pump can be powered through various means including, for example, electricity. 
     Container  302  has been described an illustrated as being attached to, or coupled to holster  200 , however this is merely exemplary. In a further exemplary embodiment of the present invention, container  302  is not attached to holster  200  but is instead in a location that is not in contact with holster  200 . 
     In one exemplary embodiment, the solution/fluid that flows through fluid tube  313  is water. It is understood, however, that other types of solutions may be used as well. Desirable solutions are solutions that are safe for human consumption. Thus, a food grade solution is desirable. Exemplary food grade solutions include chlorine bleach (diluted), hydrogen peroxide (3%), and white distilled vinegar (5%). As explained in U.S. patent application Ser. No. 14/935,664, other solutions may be used as well. The solution flowing through fluid tube  313  does so under pressure. Pressure can be supplied by a municipal water source or by a pump. Such a pump is described, and exemplary control thereof is described in U.S. patent application Ser. No. 14/935,664 
     As previously explained, beverage dispenser  100  normally sits within holster  200  when not in use. A top view of an exemplary holster is shown in  FIG. 4 .  FIG. 4  illustrates holster top member  209  that includes front member  215  and back member  216 . Holster front member  215  includes holster opening  205  into which nozzle  106  is inserted when dispenser  100  is not in use. Back member  216  may be attached to the underside of a counter by driving screws or bolts into faster openings  224  (for example).  FIG. 4  also illustrates gasket  220 . Gasket  220  may be comprised of a material that allows a seal to be formed, such as rubber. When nozzle  106  is inserted into holster opening  205 , and a cleaning solution is sprayed into the interior of nozzle  106  for cleaning purposes, gasket  220  helps to prevent cleaning solution from spraying out of holster  200  through holster opening  205 . 
       FIG. 5  is a side view of holster  200 . Below holster top member  209  and coupled thereto is holster bottom member  218 . Bottom member  218  includes holster inlet  206  which is an opening into the interior of holster  200 . Holster  200  also includes holster outlet  204 . In actual use, a cleaning solution (water or another type of fluid) flows into holster  200  via holster inlet  206 . In an exemplary embodiment of the present invention, after flowing through holster inlet  206 , the cleaning solution flows upwards within holster  200  (i.e. within holster interior  240 ) until the solution reaches nozzle  106 . After being sprayed into nozzle  106 , the fluid then flows out of holster  200  via holster outlet  204 . In  FIG. 5 , gasket  220  is again shown on the top surface of holster  200 . 
       FIG. 6  is a perspective view of holster  200 . Holster inlet  206  is partially shown but mostly obscured in this figure. Back ledge  210  may be attached to the underside of a counter such as a bar counter. Holster outlet  204  appears at the bottom of holster  200  and is an opening through which cleaning solution exits from holster  200  after cleaning solution has been sprayed into nozzle  106 . Gasket  220  is shown on the top surface of holster  200 . Holster opening  205  appears. Nozzle  106  of dispenser  100  is inserted into holster opening  205  when not dispensing beverages. 
       FIG. 7  is a further perspective view of holster  200  which is taken from a point below holster  200 .  FIG. 7  shows that holster  200  is comprised of several components, including top member  209  (that includes back ledge  210 ) and bottom member  218 . Top member  209  and bottom member  234  may each be manufactured separately and then coupled together to form holster  200 . Holster  200  may be formed of a resin such as plastic and the components thereof may be manufactured using a manufacturing process such as injection molding. The composition and method of manufacturing holster  200  are merely exemplary as it is understood that other materials and manufacturing processes may be used. 
       FIG. 8  is a cross-sectional side view of holster  200 . In  FIG. 8 , it can again be seen that holster  200  is comprised of top member  209  and bottom member  218 . Top member  209  and bottom member  218  may be joined together in a variety of different ways. In one exemplary embodiment, top member  209  includes slots  236  which are engaged by tabs that project from the top of lower member  218 . Holster  200  includes interior  201  in which nozzle  106  of dispenser  100  is cleaned. In order to clean nozzle  106 , elbow member  230  may be included within compartment  201 , although the configuration of elbow member  230  is merely exemplary. Also, as illustrated, elbow member  230  is coupled to holster inlet  206 . 
     During actual operation, nozzle  106  of dispenser  100  is inserted into holster  200  via holster opening  205 . In this manner, nozzle  106  directly faces the opening of elbow member  230  that is projecting upwards within compartment  201 . A cleaning solution is allowed to flow into holster inlet  206 . The cleaning solution then flows through elbow member  230  and exits elbow member  230  at a top opening thereof. The cleaning solution (fluid), under pressure, continues to rise within compartment  201  until it reaches nozzle  106 . The cleaning solution continues to be sprayed onto nozzle  106  for a predetermined amount of time, and then flow of the cleaning solution is terminated. As the fluid cleans nozzle  106 , the fluid then drops under the force of gravity to the bottom of compartment  201 . The fluid then exits compartment  201  via holster outlet  204 . The fluid can then be coupled to a municipal drain or to a storage container for later reuse, recycling, or to be discarded. 
     In a further exemplary embodiment of the present invention, cleaning solution is introduced into compartment  201  at another location before making contact with nozzle  106 . For example, cleaning solution may be introduced into compartment  201  at a location that is above holster outlet  204 . As the cleaning solution is under pressure, the cleaning solution will again be sprayed upwards and make contact with nozzle  106  before falling under gravity and exiting holster  200  via holster outlet  204 . 
       FIG. 8  also illustrates the use of cleaning nozzle  250  that while optional is preferred. Cleaning nozzle  250  sprays cleaning solution towards nozzle  106  with a spray pattern. In exemplary embodiments of the present invention, the spray pattern is between a 15 degree and a 30 degree pattern, although a 30 degree pattern is preferred. 
     The previous explanation has described the use of a pump to spray cleaning solution towards nozzle  106  under pressure, although the use of a pump may be optional depending upon the source of the cleaning solution. For example, if the cleaning solution is water that is obtained from a public water source, the water will be pumped under pressure and the water will thus enter elbow member (or enter into interior  201 ) under pressure. A typical public water source will provide water at a pressure of 40 pounds per square inch (psi), and at that pressure the pressure is sufficient to spray water into up to four holsters  200  simultaneously (and to thus clean four nozzles  106  simultaneously). In other words, a minimum of 10 psi of cleaning solution per nozzle  106  is desirable. In such an exemplary embodiment, a valve and solenoid may be used to simply apply the pressurized water to multiple holsters  200 . In such an embodiment, once pressurized water flows through a solenoid operated valve, the water is directed through y-connections (for example) so that it is simultaneously applied to multiple holsters  200  (and to clean multiple nozzles  106 ). To direct the water (or other cleaning solution) at more than four holsters, the use of a pump in order to increase water (or other cleaning solution) pressure is desirable. 
     The use of elbow member  230  is merely exemplary. Other mechanisms may be used for spraying cleaning solution into nozzle  106 , such as is described in U.S. patent application Ser. No. 14/935,664. 
       FIG. 9  is a perspective view of top member  209 . As shown in  FIG. 9 , top member  209  includes slots  236  which are engaged by tabs that extend from the top of bottom member  218 . Again, the use of slots  236  and tabs is merely exemplary as one method of attaching top member  209  and bottom member  218 . 
       FIG. 10  is a top view of top member  209  which again shows exemplary slots  236 . 
       FIG. 11  is a perspective view of top member  209  taken from a point below top member  209 . Again, exemplary slots  236  are shown. 
     In a further exemplary embodiment, a light is included to illuminate container  302 . In this manner, it can be readily seen that a method and/or apparatus is in place to control insects such as fruit flies. Being able to see that container  302  is in place may be comforting to customers and employees. Such lighting may also arouse interest to a prospective purchaser. 
     The holster described above may be used in combination with the method and/or apparatus for cleaning beverage dispensers that is described in U.S. patent application Ser. No. 14/935,664. It is understood, however, that the method and/or apparatus described in Ser. No. 14/935,664 is merely exemplary, and the holster described above may be used in combination with other apparatuses and/or methods. 
     Over time, as dispensers  1100  are used, residue builds on surfaces of nozzles  106 , and that residue may have adverse consequences. Bacteria and/or mold may grow on the residue. The residue may attract insects such as fruit flies. When beverages are contaminated with bacteria, mold or insects, the beverages can cause sickness and disease. Furthermore, the taste of the beverage being dispensed through the residue may be adversely affected. The residue can block beverages flowing through nozzle  1106 , thus reducing the flow rate of beverages being dispensed. This may increase the amount of time needed to dispense beverages. Residue creating a blockage within dispenser  1100  can alter the ratio of carbonated water and concentrated soda flavoring which are mixed together, thus causing a flavored soda to be dispensed which has either not enough flavoring or too much flavoring; the result is the dispensing of a beverage which does not have its expected taste. A buildup of debris over time can also shorten equipment life. 
     The residue which collects on surfaces of nozzles  1106  can thus have numerous consequences, including:
         1) If beverages do not taste good, then customers are dissatisfied, and they may stop purchasing beverages at the establishment that is selling the beverages (or may even stop being customers of the establishment entirely). Furthermore, poor reviews of the establishment may appear on social media if the beverages do not taste good;   2) The residue on the surfaces of the dispenser looks unappealing and unappetizing, and customers will not want to purchase or drink beverages dispensed through the residue;   3) A “board of health” type of inspection of dispenser  1100  may result in a government entity prohibiting use of the dispenser until it has been adequately cleaned;   4) If the residue slows down beverage dispensing, then the rate at which beverages are sold may be reduced. This reduction can adversely affect profits.   5) The residue can cause soda to be dispensed with not enough or too much carbonated water.   6) The residue can shorten equipment life.   7) It is thus desirable for each nozzle  1106  to be clean and for any residue which appears on nozzle  1106  to be removed.       

     In a food service setting, and as shown in  FIG. 12A , dispenser unit  50  includes a cleaning apparatus for cleaning nozzles  1106 . The cleaning apparatus is not visible in  FIG. 1A  because it is in a storage position. In particular,  FIG. 12A  illustrates exemplary doors  188  which may be in a closed position when the cleaning apparatus is not in use. In order to clean nozzles  1106 , doors  188  and the cleaning apparatus is moved into a position for cleaning nozzles  1106  as is more clearly described below. The inclusion of doors  188  is optional. 
     Dispenser unit  50  dispenses beverages by placing a container under the respective nozzle  1106  of a dispenser from which a beverage is desired. In some food service settings, dispenser unit  50  is only available to employees. In that setting, customers tell an employee which beverages they desire and the employee obtains the beverage from the appropriate dispenser  1100 . In other food service settings, the beverages are considered “self-serve” and a customer may directly use dispenser unit  50  in order to obtain a desired beverage. 
     In the configuration shown in  FIG. 12B , doors  188  have been opened and arm  1200  is shown in a first position. This position shown may be considered to be a storage position, namely, this is the position that arm  1200  may be placed into when dispenser unit  50  is being used for dispensing beverages, doors  188  are normally closed and cleaning of nozzles  1106  is not desired. As shown, arm  1200  includes first arm member  1202  and second arm member  1204  which is substantially perpendicular to first arm member  1202 . Cleaning nozzle  1206  is shown near an end of second arm member  1204 . Supply tube  1218  is also included. Supply tube  1218  supplies a cleaning fluid to cleaning nozzle  1206 . First arm member  1202  and second arm member  1204  appear rigid in the figures, but in an exemplary embodiment of the present invention first arm member  1202  and/or second arm member  1204  are telescoping so that they may be stored in compacted form. 
     In the position shown in  FIG. 12B , arm  1200  is being stored because it is not being used. Arm  1200  includes, however, hinge  1208  at an end thereof. Hinge  1208  allows arm  1202  to rotate so that cleaning nozzle  1206  may be situated directly under dispenser nozzle  1106 . 
     Again, doors  188  are illustrated in an open position, although they are ordinarily closed when arm  1200  is in the position shown in  FIG. 12B . When arm  1200  is in the illustrated first position, it may be desirable for arm  1200  to not be visible to a person using dispenser unit  50 . Preventing arm  1200  from being visible when in the first position may be desirable for aesthetic purposes. Furthermore, in the first position, supply tube  1218  is not supplying fluid to cleaning nozzle  1206 . 
     In order for each nozzle  1106  to be cleaned, arm  1200  is desirably rotated so that cleaning nozzle  1206  is under dispenser nozzle  1106 . Rotation of arm  1200  occurs by moving arm  1200  through a variety of different positions until it is in a position that is desirable for dispenser nozzle  1106  to be cleaned. 
     As further explained below, the angle at which arm  1200  appears in  FIG. 12B  is merely exemplary. For example, arm  1200  can be stored in a variety of different positions so that arm  1200  is not obstructing nozzles  1106  while nozzles  1106  are being used to dispense beverages. 
     In  FIG. 12C , rotation of arm  1200  has already begun so that arm  1200  has now been rotated approximately 90° relative to the position in which it appears in  FIG. 12B . In the second position shown in  FIG. 12C , supply tube  1218  is still not providing fluid to cleaning nozzle  1206 . 
     Arm  1200  continues to be rotated until it is in the 3 rd  position shown in  FIG. 12D . As shown in  FIG. 12D , arm  1200  is resting along the front of dispenser  1100 . As a result of being in the position illustrated in  FIG. 12D , cleaning nozzle  1206  is now directly under dispenser nozzle  1106 . In this manner, supply tube  1218  can then provide fluid to cleaning nozzle  1206  so that fluid can flow out of cleaning nozzle  1206  and into dispenser nozzle  1106 . Also, in this position, if first arm member  1202  and second arm member  1204  telescope, these arm members would telescope for the position shown in  FIG. 12D . Specifics of how fluid is provided through supply tube  1218  and through cleaning nozzle  1206  so that dispenser nozzle  1106  may be cleaned is more clearly described below. 
     The first position shown in  FIG. 12B  is exemplary and it is understood that arm  1200  may be stored in other configurations than what is illustrated in  FIG. 12A . For example, in  FIG. 12E , arm  1200  has been rotated approximately 90° from the orientation shown in  FIG. 12B  and in the opposite direction as the orientation shown in  FIG. 12C . Thus, the orientation of arm  1200  that appears in  FIG. 12E  is both exemplary, and optional. 
       FIG. 13A  is a side view of the orientation of armed  200  that is illustrated in  FIG. 1B . As shown in  FIG. 13A , first arm member  1202  is extending substantially vertically upwards relative to dispenser  1106 . Furthermore, supply tube  1218  is again shown. As previously explained, fluid is caused to flow through cleaning nozzle  1206  as a result of being transported to cleaning nozzle  1206  via supply tube  1218 . Furthermore, in one exemplary embodiment of the present invention, supply tube  1218  is attached to arm  1200  beginning at a location near hinge  1208  and extending to dispenser nozzle  106 . In this manner, as arm  1200  rotates into various positions, supply tube  1218  is able to rotate along with arm  1200 . 
       FIG. 13B  illustrates arm  1200  from a side view and in the position that is illustrated in  FIG. 1C . 
       FIG. 13C  is a side view of arm  1200  as illustrated in  FIG. 1D .  FIG. 13C  further illustrates how in the third position, arm  1200  positions cleaning nozzle  1206  so that cleaning nozzle  1206  is directly under dispenser nozzle  1106 . This configuration is desirable for cleaning dispenser nozzle  1106  as more clearly described below. 
     In actual operation, arm  1200  is stored in, for example, the 1 st  position, and behind doors  188  when dispenser unit  50  is being used for dispensing beverages. Typically, however, there are certain times of the day when dispenser unit  50  is not dispensing beverages. For example, dispenser unit  50  may not be dispensing beverages after the food establishments in which dispenser unit  50  has been closed for the day. At that time, since dispensers  1100  will not be dispensing beverages, nozzles  1106  are desirably cleaned. In one exemplary embodiment of the present invention, optional doors  188  are opened and arm  1200  is rotated until it is in the position shown in  FIG. 12D  and  FIG. 13C . Fluid may then be sprayed upwards from cleaning nozzle  1206  into dispenser nozzle  1106 . Spraying of fluid upwards into dispenser nozzle  1106  may be performed in a variety of different manners. In one exemplary embodiment, a timer is used so that fluid is sprayed from cleaning nozzle  1206  into dispenser nozzle  1106  at a predetermined time of the day or night (i.e. when the food establishment is closed). In another exemplary embodiment, a switch is located on or near dispenser unit  50  and activation of that switch causes fluid to be sprayed from cleaning nozzle  1206  to dispenser nozzle  1106 . In a further exemplary embodiment of the present invention, fluid flows through cleaning nozzle  1206  and into dispenser nozzle  106  using both the timer and an activation switch. Thus, if employees forget to lower arm  1200  into the third position shown in  FIG. 1D  prior to the time that a timer causes fluid to flow through cleaning nozzle  1206 , an employee may manually actuate the activation switch after lowering arm  1200  into the third position at a later time. 
     In accordance with a further exemplary embodiment of the present invention, and as shown in  FIG. 14 , the cleaning nozzle may be surrounded by a ring member to catch cleaning solution and prevent splashing as cleaning solution falls towards the beverage dispenser&#39;s drip tray. 
     In accordance with a further exemplary embodiment of the present invention, an interlocking mechanism is included to ensure that arm  1200  is in the third position before fluid is permitted to flow out of cleaning nozzle  1206 . In this manner, for example, if employees forget to lower arm  1200  into the 3 rd  position, fluid will not be permitted to flow out of cleaning nozzle  206  while, for example, arm  1200  is in the first position or the second position. The interlocking mechanism can have a variety of different configurations as is known to one of ordinary skill in the art. For example, the interlocking mechanism can be a switch that is actuated after arm  1200  is placed into the third position. Such a switch can be included within hinge  1208 , situated behind arm  200  when arm  1200  is in the first position, etc. 
     In the third position, arm  1200  is oriented so that cleaning nozzle  1206  is directly below dispenser nozzle  106 . This configuration is shown, for example, in  FIG. 15 . The direction of the fluid stream  1216  is also shown in  FIG. 15 . In the configuration shown in  FIG. 15 , fluid is provided to clean nozzle  1206 , and that fluid is subsequently sprayed up into dispenser nozzle  1106  so that dispenser nozzle  1106  may be cleaned. 
     Dispenser unit  50  desirably includes a drip tray which catches drippings that flow from dispensers  1100 . The drip tray may also be used for catching fluid after it has been sprayed into nozzle&#39;s  1106 . 
     In many restaurants, dispenser unit  50  includes more than one dispenser  1100 . Many restaurants have dispenser unit  50  with multiple dispensers  1100  in order to accommodate the number of customers who wish to be served beverages and the variety of different beverages that customers desire.  FIG. 16  illustrates that valve outlets  312   a - 312   b  provide pressurized fluid to each inlet  206   a - 206   b  respectively. Valve outlets  312   a - 312   b  are described in detail below. 
       FIG. 16  is a block diagram of cleaning apparatus  300  which, in accordance with an exemplary embodiment of the present invention, provides fluid to each cleaning nozzle  1206 . Cleaning apparatus  300  illustrated in  FIG. 16  thus provides fluid under pressure which is received by cleaning nozzle  1206  and which is then propelled upwards towards dispenser nozzle  1106  in order to clean dispenser nozzle  1106 . 
     Cleaning apparatus  300  shown in  FIG. 16  is controlled by transmitter  330 . Transmitter  330  allows fluid to be directed into inlet  106  at one or more specified times. Transmitter  330  may receive instructions from microprocessor based controller  335  which is programmed to instruct transmitter  330  to signal power supply  320 . In an exemplary embodiment of the present invention, controller  335  is a DirectLOGIC Micro Programmable Logic Controller (DL05 PLC) which is manufactured by AutomationDirect. This programmable logic controller (PLC) is programmed in accordance with the DL05 Micro PLC User Manual, volumes 1 and 2, 6 th Edition, Rev. C, February 2013 which is hereby incorporated by reference in its entirety. Transmitter  330  via controller  335  is used to control valves  310   a ,  310   b  which permit fluid to flow into inlets  1206  of respective holsters  1200 , thus cleaning respective nozzles  1206 . Thus, controller  335  has stored therein the current clock time (controller  335  increments the current clock time as time progresses so that the current clock time stored in controller  330  is correct). Basically, when the current clock time stored in controller  330  reaches a predetermined time, controller  330  instructs valves  310   a,b  to open, thus causing fluid to flow into cleaning nozzles  1206 . After a predetermined period of time has elapsed, controller  335  instructs valves  310   a,b  to close, thus causing fluid to cease flowing into cleaning nozzle  1206 . Controller  335  then waits until the next time that valves  310   a,b  are to be opened, and then repeats the cycle of opening and closing valves  310   a,b.    
     Controller  335  instructs valves  310   a,b  to open and close via power supply  320 . In an exemplary embodiment of the present invention, power supply  320  is a PS-6012 manufactured by Altech Corp. and is installed and operated in accordance with the Altech Corp. PS-60 data sheet which is hereby incorporated by reference. 
     Controller  335  signals power supply  320  via controller outputs  331   a,b . Power supply  320  subsequently provides 12 volt signals to valves  310   a, b  responsive to being signaled by outputs  331   a,b  respectively. Thus, a positive signal on controller output  331   a  causes power supply  320  to transmit a 12 volt signal on power supply output  321   a . Furthermore, a positive signal on controller output  331   b  causes power supply  320  to transmit a 12 volt signal on power supply output  321   b . When the positive signal is removed from controller output  331   a , output  321   a  ceases to provide a 12 volt signal. When the positive signal is removed from controller output  331   b , output  321   b  ceases to provide a 12 volt signal. 
     Valves  310   a, b  are valves which regulate flow of liquid. In an exemplary embodiment of the present invention, valves  310   a, b  are 12 VDC solenoid valves (i.e. valves with 12 volt relays) plastic ½″ manufactured by Zilong. When valves  310   a,b  receive 12 volt signals on their respective control inputs, the valves open and fluid provided at the valves&#39; input is allowed to flow out the valves&#39; output. When the 12 volt signals are removed from each valves&#39; control inputs, the valves close and fluid is not permitted to flow out of each valves&#39; output. A desirable flow rate for the output of each valve is, for example, 1 gallon per minute. 
     Thus, power supply outputs  321   a,b  are connected between power supply  320  and valves  310   a, b . When power supply  320  places a 12 volt signal on power supply output  321   a , valve  310   a  opens. When power supply  320  places a 12 volt signal on power supply output  321   b , valve  310   b  opens. When the respective 12 volt signals are removed from each respective power supply output, the respective valve closes. 
     Valves  310   a,b  receive fluid via valve inlets  311   a,b  respectively. Valve inlets may be pipes or tubes (e.g. flexible tubes) having, for example, a diameter of ⅜″. Valve inlets  311   a,b  receive fluid via pressurized fluid source  315 . Pressurized fluid source  315  includes branch  316  which directs fluid under pressure to valve inlets  311   a,b . Thus, when valve  310   a  opens, fluid from valve inlet  311   a  is permitted to flow through valve outlet  312   a . Furthermore, when valve  310   b  opens, fluid from valve inlet  311   b  is permitted to flow through valve outlet  312   b . Valve outlet  312   a  is connected to inlet  206   a  and valve outlet  312   b  is connected to inlet  206   b . Thus, when valves  310   a,b  open, fluid is directed to holsters  200  in order to clean nozzles  106 . 
     Pressurized fluid source  315  delivers pressurized fluid from a pressurized fluid source. The pressurized fluid source can be, for example, pressurized water from a municipal water source. Alternatively, the pressurized fluid source can be otherwise. For example,  FIG. 17A  illustrates an exemplary embodiment of the present invention in which fluid is stored in tank  410 . Pump  414  pumps fluid out of tank  410  via supply tube  412  and into pressurized fluid source  315 . Pump  414  may be actuated by controller  335  (via power supply  320 ). Pump  414  should have sufficient power (suction) to pump fluid out of tank  410  to holster(s)  200 . In an exemplary embodiment of the present invention, pump  414  is a PM300 Perimax pump manufactured by Simply Pumps. 
     The fluid used to clean nozzle  106  may be for example a fluid which is safe for human consumption. Thus, a food grade solution is desirable as the fluid to be stored in tank  410 . Exemplary food grade solutions include chlorine bleach (diluted 1 teaspoon to 1 quart of water, hydrogen peroxide (3%), and white distilled vinegar (5%). Other liquids may be used as the fluid within tank  410 . Exemplary fluids which may be used within tank  410  include, for example: a) citric acid (with an exemplary concentration of between 2.5% and 35%) b) lactic acid (with an exemplary concentration of between 2.5% and 60%); and c) peracetic acid (with an exemplary concentration of between 1% and 22%). Other food sanitizing surface agents may also be used, including Steramine. Water may also constitute a “fluid.” Furthermore, fluid source  315  may optionally include a y-junction  420  and valves  416 ,  418  which allows the fluid flowing into pressurized fluid source  315  to alternate between the fluid stored in tank  410  and water obtained from a commercial water supply  430 . Controller  335  can thus allow solution from tank  410  to clean nozzle(s)  106  for a first amount of time (by actuating valve  416 ), and to then allow water from a commercial water source to clean nozzle  106  for a second amount of time (by actuating valve  418 ). 
     In a further alternative embodiment of the present invention, tank  410  is eliminated and all cleaning is done simply using fluid from water source  430 . Water source  430 , may be, for example, a municipal water source. If the municipal water source is supplying water with sufficient pressure, then the pressure provided by the municipal water source may be sufficient to clean nozzle  106 . 
     In a further exemplary embodiment of the present invention, an additional pump  435  is used with the water from water source  430  in order to increase the pressure of water being received from water source  430 . Pump  435  may be used, for example, on demand. Thus, for example, a water pressure of 40 PSI from water source  430  may be desirable to clean nozzle  106 . Pump  435  may be omitted if the water pressure from water source  430  is approximately 40 PSI or higher, Pump  435  may be included if the water pressure from water source  430  is below 40 PSI. If pump  435  is operated on an on demand basis, the pump  435  is activated if water pressure from water source  430  is below 40 PSI and pump  435  is deactivated (allowing water to pass through without boosting water pressure) if water pressure from water source  430  is 40 PSI or greater. A water pressure of 40 PSI is merely exemplary, and it is understood that a water pressure at which operation of pump  435  is desirable may be higher or lower depending upon individual circumstances. 
     In a further embodiment of the present invention, pump  435  may be used in combination with a fluid pressure detection switch. Thus, for example, if water pressure from the water source drops below a predetermined limit (e.g. 24 PSI) then the fluid pressure switch detects the lower pressure and activates the pump automatically. Thus, fluid is sprayed towards nozzle  106  without a pump assist if fluid pressure from the fluid source is above 24 PSI (for example) and fluid is sprayed towards nozzle  106  with a pump assist if fluid pressure from the fluid source is below 24 PSI (for example). 
       FIG. 16  and  FIG. 17A  illustrate various exemplary valves  310   a ,  310   b  and  418 . One or ordinary skill in the art, however, may replace all of the various valves with a single valve (and/or a single source of fluid pressure). Thus, when the single valve is open (and/or fluid pressure is available), fluid is sprayed to all nozzles  1106 . When the single valve is closed (and/or fluid pressure is not available), fluid is not sprayed to all nozzles  1106  (or to no nozzles  1106 ). Exemplary locations to place a single valve include just prior to branch  316 , or at a point downstream from pump  414  (if pump  414  is included) or pump  435  (if pump  435  is included). 
       FIG. 17B  illustrates an alternative embodiment of the present invention. As shown, fluid is directed under pressure to different nozzles  1106  of respectively different dispensers  1100 . Fluid arrives under pressure via pressurized fluid source  315  and is directed to valve outlets  312   a,b  via branch  316 . There are several ways that fluid under pressure is provided to pressurized fluid source  315 :
         Pump  414  and valve  416  may be provided. Fluid from a source of fluid pumped with pressure via pump  414  to valve  416 . When valve  416  is open, fluid under pressure arrives at pressurized fluid source  315 . When valve  416  is closed, fluid is prevented from arriving at pressurized fluid source  315 . Valve  416  and pump  414  can be controlled by controller  335  and power supply  320  as described above.   Pump  414  may be provided and valve  416  may be omitted. When pump  414  is on, fluid from a source of fluid is pumped with pressure via pump  414  to pressurized fluid source  315 . When pump  414  is off, fluid from a source of fluid (not under pressure) is prevented from arriving at pressurized fluid source  315 . Pump  414  can be controlled by controller  335  and power supply  320  as described above.   Valve  416  may be provided and pump  414  may be omitted. This embodiment may be used if the source of fluid is providing fluid to valve  416  under pressure. Fluid may be provided under pressure if the source of fluid is, for example, a municipal water supply. As previously explained, it is desirable for the amount of pressure in the fluid transmitted to pressurized fluid source to be sufficient to clean residue off of nozzles  106 . Thus, when valve  416  is open, fluid from a source of fluid flows to pressurized fluid source  315 . When valve  416  is closed, fluid from a source of fluid is prevented from arriving at pressurized fluid source  315 .       

     Each of the above alternative embodiments enables pressurized fluid from a single source to arrive at pressurized fluid source  315 , to flow through branch  316 , and to then be sprayed onto multiple nozzles  106  via valve outlets  312   a,b.    
       FIG. 18  is a flow chart diagram which illustrates an algorithm which may be used by controller  335  in accordance with an exemplary embodiment of the present invention. At step  610  a clock is activated with a time (e.g. the current time). At  620 , the time from the clock activated at step  610  is compared with a prestored time. If, at step  630  the clock and the prestored time are the same, then at step  640  controller  335  signals for valves  310   a,b  to open so that fluid flows through valve outlets  312   a,b  and nozzle(s)  106  can be cleaned. The valves are signaled to remain open until, at step  650 , enough time has passed that nozzle(s)  106  are clean. In an exemplary embodiment of the present invention, the valves are opened once a day for 30 seconds. One of ordinary skill in the art, however, will understand that the valves can be opened more than once per day and for more than 30 seconds. At step  660 , processing waits until the following day. Processing then proceeds to step  620  where the loop is repeated. 
     In accordance with an exemplary embodiment of the present invention, it is desirable to allow fluid to be sprayed out of valve outlets  312   a,b  at predetermined times. Thus, when a predetermined time is reached (e.g. 4 AM, 8 AM etc.) valves  310   a,b  are opened and pressurized fluid flows out of valve outlets  312   a,b  and towards nozzle  106 . The predetermined time may be chosen based upon times that beverages are typically not being served from dispenser  100  (such as a when a bar or restaurant is closed). At such times, nozzles  106  are resting in holsters  200  as they are not being used. 
     In an exemplary embodiment of the present invention, in order to ensure that sufficient pressure is delivered to each nozzle  102 , valves  310   a, b  can be opened sequentially instead of at the same time. Thus, valve  310   a  can be opened, kept open, and closed before valve  310   b  is opened, kept open and closed. 
     While the above exemplary embodiment illustrates controller  335 , it is understood that controller  335  can be replaced with other methods and apparatus for controlling cleaning apparatus  300 . For example, controller  335  can be located at a remote site and can communicate with transmitter  330  via a Wi-Fi connection. Thus, a Wi-Fi receiver can receive signals over a wireless connection and can then signal power supply  320  to open and close valves in order to perform nozzle cleaning. It is understood that other forms of communication (wired and wireless) may also be used. 
     In actual practice, it is desirable for power supply  320  and controller  335  (or a Wi-Fi receiver if power supply  320  is controlled remotely) to be mounted in a box, such as a box with a screw on panel, in order to protect power supply  320  and controller  335  from tampering. Valves  310   a  and  310   b  can be mounted, for example, next to such a box and near tank  410  and/or a commercial water supply. The box and valves  310   a,b  can be located away from the bar area in order to avoid unnecessary crowding of the bar area. Valve outlets  312   a,b  can be routed through walls and/or floors to be connected to inlet  206 . In this manner, power supply  320  and controller  335  can be placed in a desirable location in order to clean a plurality of dispensers  100  located in respectively different physical locations. 
     In an alternative embodiment of the present invention, the fluid that is flowing through valve outlets  312   a,b  can be heated. In this manner, effectiveness of the fluid in disinfecting nozzle  106  can be enhanced. A fluid heating mechanism (for example an instant hot water dispenser manufactured by InSinkErator) can be used to heat fluid before it reaches nozzle  106 . Exemplary locations to place an instant hot water dispenser include along valve outlets  312   a,b , valve inlets  311   a,b , or anywhere before or after valve  416  and/or valve  418 . 
       FIGS. 12B-12E and 13A-13C  illustrate only one arm  1200 , however it is understood that a separate arm may be available to clean each beverage dispenser, respectively. Furthermore, it is possible that each arm is separately actuated to pivot and assume a position so that each cleaning nozzle is under a respective beverage nozzle. Alternatively, each arm can be coupled to a neighboring arm so that all arms pivot into position together when any of the individual arms are rotated into position. 
     The above description and illustrations show fluid flowing into two valve outlets  312   a,b  via branch  316 . It is understood, that the description of two valve outlets is merely exemplary, and the actual number of valve outlets may be two or greater. In this manner, two or more cleaning nozzles  206  of respective arms  200  can be included in accordance with the exemplary embodiments set forth above. 
     The above description describes opening valves and/or engaging a pump for a certain amount of time in order to clean nozzles  1106 . One or ordinary skill in the art will recognize that there are methods for determining how much cleaning fluid is sprayed on each nozzle  1106 . For example, instead of measuring the amount of time fluid is being sprayed onto nozzles  1106 , one can spray cleaning fluid onto nozzles  1106  based on the amount of cleaning fluid being sprayed. Thus, for example, a dosing pump can be used to deliver a certain amount of cleaning fluid to nozzles  1106 . Permitting and then stopping cleaning fluid from spraying onto nozzles  1106  can thus be a function of the amount of cleaning fluid sprayed, the amount of time during which cleaning fluid is sprayed, or both. 
     In a further exemplary embodiment of the present invention, an additional tube is directed towards the drain at which holster  1200  drains. This additional tube can direct a sanitizing solution towards the drain to prevent fruit flies from accumulating near the drain. The sanitizing solution can be permitted to flow into the drain by use of the controller described above, and this sanitizing solution can be permitted to flow into the drain at a predetermined time of day. 
     In a further exemplary embodiment of the present invention, an electronic memory stores a record of when cleaning fluid is permitted to flow towards nozzle  106  (and optionally for how long). In this manner, a record is maintained to ensure compliance with a regular cleaning schedule. 
     The method and apparatus described above provides numerous advantages over the prior art:
         The apparatus described above is attached to arm  1200  using tubes. Therefore, the controller, power supply and valves can be located at a location away from dispenser unit  50 . Thus, for example, controller  335  and power supply  320  may be located in a place which is away from customers and/or away from directly behind a bar. Controller  335  and power supply  320  can be housed in a “Bud” box and valves  310   a,b  can be located near the “Bud” box. Valve outlets  312   a,b  can be comprised of many feet of tubing. The tubing can be hidden under a bar counter and the tubing can extend to each dispenser  1100 . In this manner, multiple nozzles  1106  can be cleaned without placing the equipment needed to clean nozzles  1106  in inconvenient locations where a bar tender is attempting to work. The length of the tubing may determine the amount of power desirable in pump  414  to be able to pump fluid to each cleaning nozzle  1206  to clean each dispenser nozzle  1106 .   By streaming fluid at nozzles  1106  when the bar or restaurant is closed, it is unnecessary to clean nozzles  1106  after each use. When the bar or restaurant is closed and nozzles  1106  are not being used, fluid can be directed to nozzles  1106  for an extended period of time without interfering with a bartenders need to use the dispenser, especially during a busy time in the bar or restaurant.       

     The examples that are illustrated show exemplary embodiments of the present invention being used in combination with a beverage dispenser that dispenses by pushing pushbuttons on a front thereof. It is understood, however, that the beverage dispenser may dispense using other structure and methods, such as mechanical arms that pushed by cup as the cup is positioned under the nozzles, sensors that detect when a cup has been positioned under a dispenser, etc.
