Carbonated Fluid Dispenser with Ultrasonic Foaming Mechanism

Abstract

The embodiment relates to beverage dispensing, and more particularly to the dispensing of a carbonated beverage, from any container into a vessel, providing a portion of the beverage as foam atop the dispensed beverage. To avoid the reduction of absorbed carbon dioxide in a carbonated beverage, increased atmospheric pressure is employed to move the beverage from the container through the apparatus and into the vessel. An oscillating means provides a sonic wave through the conduit and the liquid therein; the sonic wave initiates the reaction between the carbon dioxide and the ingredients in the beverage to cause the liquid to foam prior to dispensing into the vessel. Iterations include an adaptable apparatus for a beer tap and a means for passing the liquid to be dispensed through a permeable container filled with soluble material or a permeable container filled with a filtration means.

DESCRIPTION

[0019] As discussed in greater detail below, an apparatus and method providing dispensed liquid and dispensed, foamed liquid is described. In general, a beverage container is placed in the body with the conduit inserted into the liquid that is in the container. With the upper housing closed and creating a fluid-tight, or in this case, an air-tight seal, over the open side of the body, the control lever may be moved in the first direction wherein the pump increases the air pressure inside the body. The increased air pressure in the body moves the beverage by the property of displacement, through the conduit and into the container. When the lever is moved to a second position the high frequency oscillation means produces a sonic wave through the conduit and hence through the liquid being dispensed. The high frequency produces a fine, dense foam that floats on top of the dispensed beverage. The lever may subsequently be moved to a third position wherein the control circuit opens a valve so as to dispel the relatively higher pressure air in the interior of the body, thus returning the pressure to that of the ambient pressure.

[0020] Referring to FIG. 1, an example embodiment 100 comprises a base 110 engaged with a body 112 that is further engaged by way of a gasket 114 with an upper housing 116. One skilled in the art will understand that there are a number of methods for securing the upper housing with the body such as methods including threaded or clamping closure methods.

[0021] The body 112 is a hollow chamber closed on all but one side. The open side is engaged with a gasket 114 which is further engaged with the upper housing. A conduit 118 extends from the proximal end in the interior of the body 112 where it is intended to be inserted into the liquid 124 to be dispensed, through the upper housing where the distal end forms a spout 119. The upper housing 116 contains a control lever 125, a power source 121, a pump 120, a valve 115, a high frequency oscillation means, otherwise referred to as an oscillator 122, and a control circuit 123. The control circuit 123 directs power to the aforementioned components to achieve the following described method.

[0022] A beverage container 130 is inserted into the body 112 and the conduit 118 is inserted into the beverage 124. The upper housing 116 is closed over the body 112 and sealed against the gasket 114. The operation means or lever 125, is moved to the position relative to the dispensing of the liquid. The control circuit 122 turns the valve 115 to allow air from the pump 120 into the interior of the body 112. The control circuit 122 then turns on the pump 120 that transfers air into the interior of the body 112. As the air pressure increases inside the body 112, the liquid in the beverage container 124 is moved through the conduit 118 by the property of displacement, and out the spout 119, into the glass 126. When the user chooses to create a foamed liquid, the lever 125 is moved to the position relative to the foaming of the liquid. The control circuit 123 turns on the oscillator 122 that produces an oscillatory wave through the conduit 118 and hence through the carbonated liquid, thus causing it to foam. The oscillatory wave agitates the liquid, increasing the reaction between the carbon dioxide and the proteins and starches in the liquid producing foam 132 that floats on top of the dispensed liquid 128. When the beverage and foam have been dispensed, the lever 125 is moved to a neutral position wherein the control circuit 123 switches the valve 115 to open the purge conduit 117 so that the pressure in the body 112 exits through the purge conduit 117, thus returning the pressure inside the body 112 to that of the ambient environment. The upper housing is opened and the empty beverage container 130 removed.

[0023] In an iteration of the embodiment, a beverage container is placed in the body with the conduit inserted into the liquid that is in the container. With the upper housing closed and creating a fluid-tight, or in this case, an air-tight seal, over the open side of the body, air is pumped into the interior of the body wherein the increased the air pressure moves the beverage by the property of displacement, through the conduit and into the container. A switch sends power to a high-frequency oscillation means produces a sonic wave through the conduit and hence through the liquid being dispensed. The high frequency waves produce a fine, dense foam that floats on top of the dispensed beverage. A manually operated valve is opened to dispel the relatively higher pressure inside the body so that the air in the interior of the body may return to ambient pressure.

[0024] Referring to FIG. 2, an example embodiment 200 comprises a base 210 engaged with a body 212 that is further engaged by way of a gasket 214 with an upper housing 216. One skilled in the art will understand that there are a number of methods for securing the upper housing with the body such as methods including threaded or clamping closure methods.

[0025] The body 212 is a hollow chamber closed on all but one side. The open side is engaged with a gasket 214 which is further engaged with the upper housing. A conduit 218 extends from the proximal end in the interior of the body 212 where it is intended to be inserted into the liquid 224 to be dispensed, through the upper housing where the distal end forms a spout 219. The upper housing 216 contains a pumping lever 221, a power source 221, a pump 220, a valve 215, and a high frequency oscillation means, otherwise referred to as an oscillator 222.

[0026] A beverage 224 is poured into the body 212 and the proximal end of the conduit 218 is inserted into the beverage 224. The upper housing 216 is closed over the body 212 and sealed against the gasket 214. The valve 215 is moved to a position that closes the purge conduit 217 and opens the pump conduit 219, to allow air from the pump 220 into the interior of the body 212. The pump lever 225, is moved so as to pump air into the body 212. As the air pressure increases inside the body 212, the liquid in the beverage container 224 is moved through the conduit 218 by the property of displacement, and out the distal end, otherwise referred to as a spout 219, into the glass 226. When the user chooses to create a foamed liquid, a switch 223 is turned on, providing power from the power source 221 to the oscillator 222, thus powering the oscillator 222 that produces an oscillatory wave through the conduit 218 and hence through the carbonated liquid, thus causing it to foam. The oscillatory wave agitates the liquid, increasing the reaction between the carbon dioxide and the proteins and starches in the liquid producing foam 232 that floats on top of the dispensed liquid 228. The user may then move the valve 215 to the position wherein the purge conduit 217 is opened and conduit 219 is closed, so that the pressure in the body 212 exits through the purge conduit 217, thus returning the pressure inside the body 212 to that of the ambient environment.

[0027] Referring to FIG. 3 an iteration of the embodiment is illustrated. A base 310 supports a vessel 326 and the body 312 of the embodiment. Clamps 315 engage the upper housing 316 with the body 312. An operation means, or lever 325 actuates the control circuit that in turn operates the internal components, illustrated in FIG. 4.

[0028] Referring to FIG. 4, an example embodiment 300 comprises a base 310 engaged with a body 312 that is further engaged by way of a gasket 314 with an upper housing 316. At least one clamping means 315 engages with a portion of the upper housing 316 and the body 312. One skilled in the art will understand that there are a number of methods for securing the upper housing with the body such as methods including threaded or clamping closure methods.

[0029] The body 312 is a hollow chamber closed on all but one side. The open side is engaged with a gasket 314 which is further engaged with the upper housing 316. A conduit 318 extends from the proximal end in the interior of the body 312 where it is intended to be inserted into a container 330 that holds a carbonated beverage to be dispensed, through the upper housing 316 where the distal end forms a spout 319. The upper housing 316 comprises a lever 325, a power source 321, a control circuit 323, a pump 320, a valve 315, and a high frequency oscillation means, otherwise referred to as an oscillator 322. One skilled in the art will understand that a control circuit and subsequently engaged switches, actuators, solenoid valves and the like are powered by a cord intended for engagement with a wall outlet or a battery operated power source.

[0030] A beverage in a container 330 is placed inside the body 312 and the proximal end of the conduit 318 is inserted into the beverage container 330. The upper housing 316 is closed over the body 312 and sealed against the gasket 314 by engaging clamps 334. Movement of the lever 325 actuates a switch 323 that engages the control circuit 323 that in turn moves the valve 315 to a position that closes a purge conduit and opens a pump conduit, to allow air from the pump 320 into the interior of the body 312. As the air pressure increases inside the body 312, the liquid in the beverage container 330 is moved through the conduit 318 by the property of displacement, and out the distal end, otherwise referred to as a spout 319, into the glass 326. When the user chooses to create a foamed liquid, the lever 325 is moved to a third position wherein a signal to the control circuit, provides power from the power source 321 to the oscillator 322, thus powering the oscillator 322 that produces an oscillatory wave through the conduit 318 and hence through the carbonated liquid, causing it to foam. The oscillatory wave agitates the liquid, increasing the reaction between the carbon dioxide and the proteins and starches in the liquid producing foam 332 that floats atop the dispensed liquid 328 in the glass 326. The user may then move the lever 325 to the final position, signaling the control circuit to open the valve 315 to purge the pressure from inside the body 312, thus returning the pressure inside the body 312 to that of the ambient environment.

[0031] Referring to FIG. 5 and FIG. 6, an iteration of the embodiment is illustrated in a perspective view in FIG. 5 and a side, section view in FIG. 6. The example embodiment is intended as an integral design to be engaged with a tap 401. The tap 401 comprises a valve that allows carbonated liquid to flow from a pressurized vessel such as a keg, along a conduit 418 to the spout 419. The embodiment includes a housing 405 that contains a power supply 421 that supplies power to an oscillator 422, through momentary switch 425. The oscillator produces an oscillatory wave through the conduit 418 and hence through the carbonated liquid, causing it to foam. The oscillatory wave agitates the liquid, increasing the reaction between the carbon dioxide and the proteins and starches in the liquid producing foam 432 that floats atop the dispensed liquid 428 in the glass 426.

[0032] Referring to FIG. 7, an example embodiment 500 comprises a base 510 engaged with a body 512 that is further engaged by way of a gasket 514 with an upper housing 516. One skilled in the art will understand that there are a number of methods for securing the upper housing with the body such as methods including threaded or clamping closure methods.

[0033] The body 512 is a hollow chamber closed on all but one side. The open side is engaged with a gasket 514 which is further engaged with the upper housing. A conduit 518 extends from the proximal end in the interior of the body 512 where it is intended to be inserted into the liquid 524 to be dispensed, through the upper housing where the conduit 518 passes through a vessel 550 that may contain a filter or flavored infusion pod 552 wherein it continues to the distal end that forms a spout 519. The upper housing 516 contains a control lever 525, a power source 521, a pump 520, a valve 515, a high frequency oscillation means, otherwise referred to as an oscillator 522, and a control circuit 523. The control circuit 523 directs power to the aforementioned components to achieve the following described method.

[0034] A beverage container 530 is inserted into the body 512 and the conduit 518 is inserted into the beverage 524. The upper housing 516 is closed over the body 512 and sealed against the gasket 514. The operation means or lever 525, is moved to the position relative to the dispensing of the liquid. The control circuit 522 turns the valve 515 to allow air from the pump 520 into the interior of the body 512. The control circuit 522 then turns on the pump 520 that transfers air into the interior of the body 512. As the air pressure increases inside the body 512, the liquid in the beverage container 524 is moved through the conduit 518 by the property of displacement, and through the vessel 550 where it interacts with the filter and/or infusion pod 552 and continues out the spout 519, into the glass 526. When the user chooses to create a foamed liquid, the lever 525 is moved to the position relative to the foaming of the liquid. The control circuit 523 turns on the oscillator 522 that produces an oscillatory wave through the conduit 518 and hence through the carbonated liquid, thus causing it to foam. The oscillatory wave agitates the liquid, increasing the reaction between the carbon dioxide and the proteins and starches in the liquid producing foam 532 that floats on top of the dispensed liquid 528. When the beverage and foam have been dispensed, the lever 525 is moved to a neutral position wherein the control circuit 523 switches the valve 515 to open the purge conduit 517 so that the pressure in the body 512 exits through the purge conduit 517, thus returning the pressure inside the body 512 to that of the ambient environment. The upper housing is opened and the empty beverage container 530 removed. One skilled in the art understands that an infusion pod 552 may contain flavors or additives for enhancing the liquid and foam or for enhancing only the liquid or only the foam dispensed. One skilled in the art understands that an infusion pod may be replaced with a filter for the purpose of removing contaminants from the dispensed liquid.

[0035] Although embodiments describe liquid under pressure, one skilled in the art can understand that the invention may also work with liquid flowing through a conduit at ambient pressure.
