BACKGROUND

The present invention relates to a quick-install cleaning nozzle or cap for cleaning a diffuser of a manual beverage dispenser such as a beverage gun. More specifically, the present invention relates to a cleaning nozzle or cap for creating a high pressure fluid flow in a chamber around the diffuser or dispensing port of the manual beverage dispenser to clean the beverage dispenser easily.

Various beverage dispensers such as those found in restaurants, bars and other entertainment venues and/or food service establishments typically have a manual beverage dispenser. The dispenser may be hand-held dispenser sometimes referred to as a “soda gun.” In conventional dispensing systems with a dispensing gun, the dispensing gun is connected to a number of beverage concentrate supply sources via lines designed to deliver a specific beverage concentrate to the dispensing gun. The lines also deliver a charged water or carbonated water flow to the dispenser.

These manual beverage dispensers typically are used to dispense various liquids including those drinks having a sugar content. The manual beverage dispensers have a dispensing nozzle that covers an outlet for the liquid flow, usually through a diffuser that accumulates bacteria quickly. It is time consuming and undesirable for workers to manually clean the beverage dispenser nozzle nightly or even weekly. Cleaning generally requires disassembly of the gun to fully remove bacterial buildup or even mold that grows in the dispensing nozzle and on the diffuser. Cleaning these devices is imperative for overall sanitization and cleanliness, but also to preserve the original taste of the beverages dispensed.

DETAILED DESCRIPTION

A nozzle cap for cleaning and optionally sanitizing a diffuser of a beverage dispenser is described herein. The nozzle cap is a removable and reusable assembly configured to couple to the diffuser or outlet end of the beverage dispenser for cleaning and/or sanitizing. Most beverage dispensers are connected to a water line where the water line may be charged water and/or carbonated water. By dispensing a liquid, such as charged or carbonated water, with the beverage dispenser, the nozzle cap coupled to the beverage dispenser produces a cleaning flow which can safely and effectively flush clean the diffuser and the surface area behind and/or around the diffuser which directs fluid flow from the outlet for beverage delivery from the system.

The cleaning flow is an actual change to the fluid flow dynamics of the fluid leaving the beverage dispenser, generally through the diffuser or similar flow control element. That is, the cleaning flow physically removes built up debris on surfaces of the beverage dispenser diffuser and when a sanitizing component is provided therewith, also sanitize the surfaces. The flow from the beverage dispenser is a generally laminar flow through a diffuser mechanism, wherein the cleaning flow generated by the nozzle cap described herein may be a non-laminar flow, a flow with eddies, swirls, or currents normal to the flow itself, a turbulent flow, or in some embodiments a vortex. The flow is sufficiently pressurized and/or turbulent within the cleaning nozzle and as directed by the cleaning nozzle surfaces to clean the diffuser of the beverage dispenser.

In one or more embodiments, the nozzle cap is also configured to support a supply of sanitizer therein such that the cleaning chamber can be provided with a sanitizing material for coupling to the beverage dispenser. The sanitizing material is then used with the liquid cleaning flow to clean and sanitize the beverage dispenser, diffuser, and its surface areas where bacteria, mold and other organic material may accumulate. The sanitizing material may be a tablet or solid material that dissolves in water to sanitize surfaces by wiping or soaking the surface with the sanitizing solution formed.

The nozzle cap has one or more internal surfaces that produce the cleaning flow when liquid is dispensed from the beverage dispenser. The liquid flow from the beverage dispenser through its outlet and/or diffuser is not adjusted, but rather exits the beverage dispenser and is directed into and against one or more internal surfaces of the nozzle cap, which change the fluid flow from the beverage dispensing diffuser into a non-laminar, turbulent fluid flow or other physical cleaning flow. The cleaning flow is formed inside the cleaning nozzle coupled to the beverage dispenser and the fluid thus surrounds and contacts the diffuser surfaces at one or more angles, including at least the inner surfaces of the diffuser where bacteria and mold may accumulate. The cleaning flow thus physically removes built up material on these beverage dispensing and/or diffuser surfaces. In embodiments where a sanitizing material is provided to the nozzle cap, the cleaning flow is also a sanitizing cleaning flow which further cleans and sanitizes the inner surfaces of the beverage dispenser including the diffuser.

The nozzle cap is a cleaning and sanitizing device that is removable and reusable. The nozzle cap cleans a preexisting beverage dispensing diffuser, without removal of the diffuser from the beverage dispensing system and without requiring modification to the normal operation of the beverage dispensing system. The diffuser may be provided with a dispensing nozzle over the diffuser, which may or may not be removed when the cleaning nozzle cap is coupled to the beverage dispenser. The nozzle cap is removably coupled to the dispensing end and/or around the diffuser end of the beverage dispenser and charged or carbonated water is dispensed from the dispenser and into the cleaning nozzle cap. The nozzle cap uses the beverage dispensing systems own water flow rate and water pressure in combination with the internal structure and surfaces of the nozzle cap to create a change in the fluid flow into the cleaning flow within the cleaning nozzle to remove bacteria, mold, and other grime or buildup inside and around the diffuser and to flush the dispenser diffuser and surfaces therearound clean. Optionally, detergents or other sanitizing products can be provided to the nozzle cap for sanitizing the diffuser connected thereto. The nozzle cap can be coupled to the beverage dispenser and removed from the dispenser manually and without the use of additional tools or hardware. The cleaning nozzle cap is secured to the beverage dispenser by a mechanism capable of withstanding the pressure generated from the fluid flow from the beverage dispenser without popping off the beverage dispenser.

The cleaning nozzle cap described herein effectively throttles the fluid flow from the beverage dispenser and directs at least some of the fluid flow direction back towards the diffuser for cleaning. The fluid is drained from the outlet end of the cleaning nozzle cap during cleaning but the flow through the nozzle cap is distinct from the flow generally ejected from the beverage dispenser without the cleaning nozzle cap coupled thereto.

In one or more embodiments illustrated herein the beverage dispenser is a manual beverage dispenser and more specifically is a hand-held beverage dispenser. The nozzle cap described in one or more embodiments herein may be used with any such beverage dispenser having a fluid dispensing outlet, which includes a diffuser or like element for fluid flow control, including hand-held beverage dispensing “guns.”

In one or more embodiments and referring toFIGS.1-3, the nozzle cap10is a housing12having a base end14with opening or inlet16configured for receiving a diffuser30of a beverage dispenser therein. An interior surface of the base end14may comprise one or more surface elements or mechanisms26for securing the nozzle cap10to the diffuser30inserted therein.

A tip end18of the housing12may be conical in shape along its length and truncated at a terminal end thereon. The tip end18supports one or more internal surfaces20which generate or form a turbulent fluid flow in the liquid ejected from the diffuser30inserted into the nozzle cap10.

The tip end18may have an opening or a drain port28in the terminal end. The tip end18may also have one or more spaces configured for receiving and/or supporting the addition of a sanitizing material such as a powder, tablet, or fluid within the nozzle cap10. The nozzle cap10may support the addition of sanitizing material within the cap10such that the fluid flow from the diffuser30contacts, dissolves and/or carries the sanitizer in the fluid and in the non-laminar and/or turbulent flow to sanitize and clean interior surfaces of the diffuser30. Sanitizer may be provided at or near the drain port28or held by the one or more internal surfaces20which generate or form the turbulent fluid flow in the liquid.

In the embodiment illustrated inFIGS.1-3, the one or more internal surfaces20comprise a conical surface21having a length that extends from the tip end18of the nozzle cap10towards the base end12and wherein this conical surface21has dimensions such that the conical surface21is positioned within the interior of the tip end18and an outlet end24of the conical surface21is positioned at, near or partially extending into an outlet of the diffuser30to direct the fluid ejected therefrom into the turbulent flow. The conical surface may have an interior and exterior surface configuration such that the turbulent flow generated is a cleaning flow34within the interior of the diffuser30as shown inFIG.3.

The surface elements or mechanisms26for securing the nozzle cap10to the diffuser30inserted therein may comprise spaced apart tabs or protrusions from the interior surface of the base end12such that these spaced apart tabs26couple to the external surface geometry of the diffuser30to securely but removably couple the nozzle cap10to the beverage dispenser32. The mechanism for coupling the nozzle cap10to the beverage dispenser32may also include threaded fastening means or other means sufficient to retain a sealed connection between the nozzle cap10and the beverage dispenser32while high pressure flow is generated during cleaning. Fluid is generally ejected from the diffuser30of a beverage dispenser32at a flow rate in the range of 1.25-3.8 oz/second and the pressure on the fluid line in manual beverage dispensing systems can operationally be in the range of 130-150 PSI. Using charged water or carbonated water as the fluid dispensed from the diffuser30, the otherwise laminar water flow from diffuser30is directed into a cleaning flow34by the coupling of the nozzle cap10to the beverage dispenser32during fluid dispensing. The charged or carbonated water is dispensed for a selected amount of time and the cleaning flow34generated within the diffuser30for cleaning and optionally sanitizing as well.

The nozzle cap10according to one or more embodiments can be coupled to the beverage dispenser32to clean the diffuser and adjacent surfaces without significantly adjusting the fluid flow of the fluid dispensed through the diffuser. That is, the cleaning flow is generated by the cleaning nozzle cap under normal or standard beverage dispensing settings. No additional equipment or pumps are needed to increase the pressure or flow rate of the dispensed fluid for cleaning. The nozzle cap10cleans the dispenser30by way of dispensing the fluid, generally water, from the nozzle with the cap10thereon for a selected duration of time that may be adjusted based on the extent of buildup on the nozzle surfaces for example. The cap10may be coupled to the nozzle and fluid dispensed from the beverage dispenser through the nozzle for a time in the range of about 2 seconds to 5 minutes or more, and optionally in the range of about 3 to 5 seconds. In one or more embodiments, cleaning of the nozzle is completed with a fluid dispensing time of under about 5 minutes, under about 2 minutes, under about 30 seconds or under about 5 seconds with the cap10coupled to the beverage dispenser32.

A sanitizing material, for example, a tablet can be inserted into the cap10and dissolved by the water flow though the cap10and into the diffuser30. The duration of the cleaning may then be dependent on the contact time or “soaking time” required by the specific sanitizing chemical to effectuate sanitizing of the surfaces of the nozzle.

In one embodiment as illustrated inFIGS.4-5, the nozzle cap10is cylindrical along the base12with an open interior and the tip end18is a truncated cone with an interior surface36that may also be sloped along the length of the tip end18towards the drain port28. The cleaning flow creator20is also a truncated cone wherein the opening24extends near the base end12of the nozzle cap10. The conical surface21may have a sloped length that extends from the terminal end or drain port28of the nozzle cap10inwardly towards the base end12of the nozzle cap wherein the length of the conical surface is in the range of about ½ to about ⅓ the overall length of the nozzle cap10.

The tip end18has an interior surface36that may be sloped in a manner that corresponds to the exterior surface dimensions of the tip end18. The interior surface36may further have a curvature. The direction of the slope of the conical surface21may be opposite to the direction of the slope of the exterior surface of the tip end18and may further be opposite the direction of the slope of the interior surface36of the tip end18. There remains an open interior cavity or space38between the interior surface36and the vortex creator20within the tip end18.

In one or more embodiments, the nozzle cap10is a unitary and monolithic housing formed by injection molding with a hard plastic material. In one or more embodiments the nozzle cap10is generally a housing12having a first end with an opening16for connecting or coupling to the diffuser30of a beverage dispenser32and comprising a cleaning chamber18and a cleaning flow creator20with a drain port28in a second end of the housing12. The nozzle cap10has a mechanism26to securely and removably couple the nozzle cap10the diffuser30. The mechanism26may comprise one or more tabs or openings in the surface that frictionally engage with the exterior surface of the diffuser30.

In the embodiment illustrated inFIG.6, the nozzle cap10may comprise a tab40or other surface extending from an exterior surface of the cap10and having an aperture42therein which allows for connection of a lanyard or other mechanism or accessory, and/or allows the cap10to by hung on a hook or the like for drying or storage via connection with the aperture10.

The nozzle cap according to one or more embodiments herein allows for a quick cleaning of the diffuser and/or adjacent surfaces of the beverage dispenser and thus eliminates an environment that attracts fruit flies, which can be especially prominent in warmer climates. Use of the nozzle cap also eliminates the need for overnight or long soaking of hand-held beverage dispensers. For example, one practice used may be to soak the hand-held beverage dispenser or “bar gun” in a pitcher of water with cleaning agent overnight. This practice can result in damage to the beverage gun and nozzle including pitted stem controls and/or cause leaks. This practices further fails to remove built up materials. Use of the cleaning nozzle as described here eliminates the need for such a practice and can extend the useful life of the beverage dispenser.
