Title: Device and method for nucleation of a supercooled beverage

Description:
FIELD 
     Embodiments described herein generally relate to devices and methods for forming a slush beverage. Specifically, embodiments described herein relate to devices and methods for causing nucleation of a supercooled beverage in a beverage container using ultrasonic energy to form a slush beverage within the beverage container. 
     BACKGROUND 
     Consumers may choose to purchase a packaged beverage, such as a bottled or canned beverage, rather than a fountain or draft beverage for a variety of reasons. Packaged beverages provide improved portability relative to fountain or draft beverages which are often dispensed into cups, as the packaged beverage, may be sealed and resealed and may be stored in a bag, lunchbox, or the like. Additionally, some consumers may prefer the experience of drinking directly from a can or bottle rather than drinking from a plastic or paper cup. 
     Packaged beverages, however, are typically limited to liquid beverages, and packaged beverages generally do not contain slush beverages. Slush beverages can be desirable where the consumer wishes to enjoy a cool and refreshing beverage with a unique texture. Additionally, a slush beverage may remain cool for a longer period of time than a beverage that has simply been refrigerated. As the slush beverage is partially frozen, the slush beverage is not diluted when the frozen portion of the slush beverage melts. Thus, there is a need in the art for devices and methods for preparing a slush beverage within a beverage container.

     DETAILED DESCRIPTION OF THE INVENTION 
     Reference will now be made in detail to representative embodiments illustrated in the accompanying drawing. It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the claims. 
     A slush beverage may be formed within a beverage container by cooling the beverage to a temperature at or below the freezing point of the beverage, and subsequently agitating the beverage so that the beverage turns into a partial solid or slush. Upon agitating the beverage, the beverage may nucleate causing formation of crystals within the beverage that propagate throughout the beverage, turning the beverage into a slush beverage. 
     Consumers may enjoy the ability to select a supercooled beverage and prepare a slush beverage. Consumers may also enjoy the opportunity to view nucleation of the beverage as the beverage transitions from a liquid to a slush beverage. The ability to watch the nucleation process may provide consumers with a unique and entertaining experience, and may encourage consumers to make additional purchases. 
     However, nucleation of the beverage may be difficult to view depending on the method of agitation. For example, it may be difficult or impossible for a consumer to view the nucleation of the beverage within the beverage container if the beverage is nucleated by dropping the beverage container onto a surface or by shaking the beverage container. Further, some devices for nucleating a beverage may obscure parts of the beverage container such that the nucleation of the beverage cannot readily be viewed. Additionally, other methods of nucleating a beverage, such as striking the beverage may dent or otherwise damage the beverage container. Thus, there is a need for a device that can nucleate a beverage within a beverage container that allows a consumer to view the nucleation process. 
     Further, existing devices for nucleating supercooled beverages within a beverage container may require the consumer to carry out a series of steps to nucleate the beverage. For example, a consumer may be required to select a supercooled beverage, uncap and recap the beverage, and/or to shake the beverage. The consumer may then place the beverage in a nucleation device and perform the steps required to operate the nucleation device. As a result, such devices introduce the risk of user error. If the user is unable to cause nucleation of the beverage to produce a slush beverage, the consumer may have a poor experience and may be unlikely to make additional purchases. Therefore, there is a need in the art for systems and methods that allow consumers to readily produce a slush beverage and that minimizes the risk of user error. 
     Some embodiments described herein relate to a beverage nucleation device that uses ultrasonic energy to cause nucleation of a supercooled beverage within a beverage container. In this way, the beverage nucleation device allows for easy and rapid formation of a slush beverage within a beverage container without having to shake, drop or strike the container, which may cause damage to the container. Further, the use of ultrasonic energy allows the beverage to be nucleated with the beverage container in a static position so that a consumer may more easily view nucleation of the beverage and the transition from liquid to a partial solid or slush. 
     As used herein, the term “beverage container” may refer to a bottle, can, mug, pouch, or other suitable beverage vessel. The beverage container may be composed of glass, plastic, such as polyethylene terephthalate (PET) or polypropylene (PP), or a metal, such as aluminum, among other materials. The beverage container may have any suitable shape. For example, the beverage container may have round sidewalls and may have a generally cylindrical shape, or the beverage container may have flat sidewalls so as to have a generally square transverse cross sectional area. The beverage container may be a sealed container, such as a capped bottle or an unopened can. It is understood that the beverage nucleation device described herein is not limited to use with a specific type or size of beverage container and any of various types of bottles or cans may be used. 
     As used herein, the term “beverage” includes any consumable free-flowing liquid or semi-liquid product, which may be carbonated or non-carbonated, including but not limited to soft drinks, water, carbonated water, dairy beverages, milkshakes, juices, alcoholic beverages, sports drinks, energy drinks, smoothies, coffee beverages, and tea beverages. As used herein, the term, “slush beverage” includes any beverage that is at least partially frozen, such that the beverage is part liquid and part solid. 
     A beverage or other liquid is “supercooled” when the beverage is below a freezing point of the beverage and remains in a liquid state. While the beverage is below its freezing point, the liquid may remain in a liquid state until the liquid is agitated such that nucleation of the beverage occurs. 
     In some embodiments, a beverage nucleation device  100  for nucleating a supercooled beverage in a beverage container  500  includes a beverage container receiving area  118  for receiving a beverage container  500  containing a supercooled beverage, as shown for example in  FIG. 1 . Beverage container  500  containing a supercooled beverage may be retrieved from a cooler or refrigerator configured for storing beverages in a supercooled state (see, e.g.,  FIG. 11 ). Beverage container  500  may be formed from a material that is at least partially transparent or translucent so that the beverage contained therein is visible to the consumer so that the consumer may view nucleation of the beverage. In some embodiments, beverage container  500  may be completely transparent or translucent. In some embodiments, beverage container  500  may be entirely non-transparent or opaque. Beverage nucleation device  100  may be configured as a stand-alone device and can be positioned for use on a countertop, a table, or other support surface. However, in some embodiments, beverage nucleation device  100  may be integrally formed with a cooler for storing supercooled beverages or may be securable to the cooler. 
     Housing  110  of beverage nucleation device  100  may include an upper end  114  opposite a lower end  112 . Housing  110  is shown in  FIG. 1  as tapering from lower end  112  toward upper end  114  so that housing  110  has a trapezoidal shape when viewed from the front. However, housing  110  may have various other shapes or configurations and may be shaped as a rectangular prism, a cube, a cylinder, a semi-cylinder, among various other shapes. 
     Housing  110  defines a beverage container receiving area  118  that is at least partially enclosed by housing  110 . Beverage container receiving area  118  may receive a beverage container  500  to be nucleated. Housing  110  may further include a beverage container support  130  for supporting beverage container  500  within beverage container receiving area  118 . Beverage container support  130  is configured to support beverage container  500  in an upright or standing orientation, e.g., with a lower end or bottom of beverage container  500  positioned on container support  130 . In this way, beverage container  500  is visible to a consumer during the beverage nucleation process so that the consumer can view the transition of the liquid beverage to a slush beverage within the beverage container  500 . In some embodiments, beverage container support  130  may include a platform and pair of upstanding sidewalls  132  defining a recess  134  in which beverage container  500  may be positioned in order to facilitate proper positioning of beverage container  500  within beverage nucleation device  100 . 
     In some embodiments, beverage nucleation device  100  may include one or more gates  138 . In some embodiments, gates  138  may be used for maintaining beverage container  500  on support  130  and within slot  134  and to prevent withdrawal of beverage container  500  from beverage nucleation device  100  during operation of device  100 . Gates  138  may be movable from an open position in which beverage container can be inserted into and removed from beverage nucleation device  100 , and a closed position in which beverage container  500  cannot be withdrawn from beverage nucleation device  100 . When gates  138  are in the closed position (as shown in  FIG. 1 ), gates  138  may provide an indication to a consumer that a beverage container  500  positioned on support  130  of beverage nucleation device  100  should not be removed. Upon completion of the beverage nucleation process, gates  138  may move to the open position to signal that beverage container  500  may be removed, and to allow beverage container  500  to be removed. Gates  138  may move between open and closed positions by pivoting or rotating, such as about a hinge, or gates  138  may extend or retract from support  130 , such as from upstanding sidewalls  132  of support  130 . In some embodiments, as shown for example in  FIG. 1 , beverage nucleation device  100  includes a pair of gates  138  arranged on opposing sides of support  130 . However, in some embodiments, beverage nucleation device  100  may include only a single gate  138 , or beverage nucleation device  100  may include three or more gates. In some embodiments, gates  138  do not entirely cover beverage container  500  so as to avoid obscuring nucleation of the beverage within beverage container  500 . Thus, gates  138  may be compact and have a small profile. In some embodiments, gates  138  may be composed of a transparent material so that beverage container  500  can be viewed through gates  138 . 
     In some embodiments, beverage nucleation device  100  may further include lights  139 , such as a light strip  139 , arranged on support  130 . Light strip  139  may be configured to indicate when beverage nucleation device  100  is ready for use. Further, light strip  139  may be placed so as to partially surround beverage container  500  placed on support  130 . When beverage nucleation device  100  is not in use, light strip  139  may be illuminated in a first color, such as white. When beverage nucleation device  100  is in use, light strip  139  may illuminate in a second color that differs from the first color, such as blue, to indicate that nucleation is in progress. Further, in some embodiments, indicator light  139  may pulse when nucleation is in progress and may stop pulsing when nucleation is complete, or may return to the first color when nucleation is complete. Thus, the light strip  139  may help to guide user in operating beverage nucleation device  100 . 
     Beverage nucleation device  100  may further include an actuator  102  that can be operated by a consumer to begin nucleation of a beverage (i.e., to activate beverage nucleation device  100 ). Actuator  102  may be a push-button, a lever, a switch, a dial, a crank, or a capacitive sensor, among other types of controls or actuators. Actuator  102  may be positioned on housing  110 , such as on a front surface  111  of housing  110  so that actuator  102  is readily accessible to consumers. Thus, a consumer may position a beverage container  500  containing a supercooled beverage on support  130  and can operate actuator  102  to begin the nucleation process, as described in further detail herein. As a result, the process of nucleating the beverage is simple and requires the consumer to perform limited steps (e.g., placing a selected beverage container  500  in beverage container receiving area  118  and operating actuator  102 ). 
     In some embodiments, beverage nucleation device  100  includes an indicator  160  configured to indicate a status of a beverage nucleation process, as shown for example in  FIG. 1 . Indicator  160  may include one or more lights or a display screen, as discussed in further detail herein. Indicator  160  may simply indicate when nucleation is complete, or indicator  160  may continuously provide an indication of the status of a nucleation process. Indicator  160  may be arranged on housing  110  and may face toward a consumer operating beverage nucleation device  100 . However, in alternate embodiments, indicator  160  may be positioned on other portions of housing  110 . 
     Beverage nucleation device  100  may further include a beverage container holder  140  and an ultrasonic transducer  170 , as shown in  FIG. 2 . Container holder  140  and ultrasonic transducer  170  may be arranged within housing  110 , and may further be enclosed within housing  110  by support  130 . When container holder  140  is in a resting position, container holder  140  may be covered by a movable wall or gate so that container holder  140  is not visible from an exterior of beverage nucleation device  100 . Movable wall or gate may provide a continuous appearance with support  130  when used to cover container holder  140 . When container holder  140  is extended into an operational position, movable wall or barrier may move or rotate to allow container holder  140  to move toward and contact beverage container  500  on support  130 . Container holder  140  is configured to secure a beverage container  500  on support  130  so that beverage container  500  does not move during nucleation, and ultrasonic transducer  170  is configured to apply ultrasonic energy to a beverage container  500  arranged on support  130  in order to cause nucleation of the beverage within beverage container  500 . 
     In some embodiments, beverage nucleation device  100  includes an ultrasonic transducer  170  configured to generate ultrasonic energy (also referred to herein as “ultrasound”). In some embodiments, ultrasonic transducer  170  may be a piezoelectric ultrasonic transducer. Ultrasonic transducer  170  may be similar to ultrasonic transducers  170  suitable for use in ultrasonic cleaning baths, as will be understood by one skilled in the art. Ultrasound can be used to agitate a beverage within beverage container  500  so as to cause nucleation of a supercooled beverage. Ultrasound can be applied to beverage container  500  while beverage container  500  is maintained in a static position. By keeping beverage container  500  stationary, the consumer may be able to more easily view the beverage within beverage container  500  undergoing nucleation. Further, nucleation of the beverage can occur without having to physically impact the beverage container, i.e., without having to shake, drop, or strike the beverage container, which may damage the beverage container and reduce the visibility of the beverage undergoing nucleation. 
     In some embodiments, ultrasonic transducer  170  may be configured to apply ultrasound having a frequency 1 kHz to 100 kHz, 10 kHz to 80 kHz, or 20 kHz to 60 kHz to beverage container  500 . As the frequency falls below 1 kHz or increases above 100 kHz, the ultrasonic energy may cause little to no vibration of molecules of the beverage. As a result of lack of vibration of the beverage molecules, nucleation of the beverage may not occur. 
     In some embodiments, ultrasonic transducer  170  may apply ultrasonic energy with a power of 10 W to 100 W, 20 W to 80 W, or 40 W to 60 W. Ultrasonic transducer  170  has sufficient power to allow ultrasonic energy to pass through applicator  172  and beverage container  500  so as to reach beverage within beverage container  500 . When power of ultrasonic transducer  170  drops below 10 W, ultrasonic transducer  170  may not have sufficient power for ultrasonic energy to pass through applicator and walls of beverage container. As nucleation may occur at power is 10 W to 100 W, power greater than 100 W may not yield despite increasing energy use. 
     Ultrasonic transducer  170  may include an applicator  172  for contacting beverage container  500 , as shown for example in  FIGS. 3-4 . Ultrasonic energy may be generated by ultrasonic transducer  170  and applied to beverage container  500  via applicator  172 . In some embodiments, applicator  172  may include a pad or cushion made of a flexible material, such as an elastomer. For example, applicator  172  may include rubber, such as ethylene propylene rubber (EPDM), silicone rubber, fluoroelastomers, polyether block amides (PEBA), or nitrile rubber, among others. The inventors of the present application found that the use of a flexible material, such as elastomeric materials, allows for more efficient transfer of ultrasound energy to beverage containers and promotes nucleation of the beverage within a beverage container compared to stiffer or more rigid materials. Air is a poor transmitter of ultrasound and thus any misalignment or gaps between applicator  172  and beverage container  500  may result in significant loss of power, inhibiting transfer of ultrasound energy to beverage within beverage container  500 , and resulting in loss of power. In some embodiments, applicator  172  may include a material having a Shore A hardness of about 5. Further, in some embodiments, applicator  172  may include a material having a 100% modulus of 14 to 16 psi. 
     Applicator  172  is configured to be placed in contact with a sidewall of beverage container  500  containing a supercooled beverage to be nucleated. Applicator  172  may be sized and shaped accordingly. Applicator  172  may be positioned so as to contact a mid portion of a beverage container  500  between a lower end and an upper end of beverage container  500 . Ultrasound energy may be applied to beverage container  500  in a transverse direction of beverage container  500 . In this way, application of ultrasound to a beverage within beverage container  500  causes nucleation to first occur in a central or middle portion of beverage container  500 . Nucleation of beverage may proceed from the middle of beverage container  500  toward the upper end and toward the lower end of beverage container  500 . Application of ultrasound energy to a sidewall of beverage container  500  is believed to allow nucleation of the beverage to occur more rapidly than application of ultrasound to an upper end or lower end of beverage container  500 . However, in some embodiments, applicator  172  may be configured to contact an upper portion or a lower portion of a sidewall of beverage container  500  such that ultrasonic energy is applied to beverage container in a transverse direction at the upper portion or lower portion of beverage container  500 . In some embodiments, applicator  172  may be configured to contact a top surface or a bottom surface of beverage container  500 . 
     Applicator  172  includes a contact surface  174  configured to be placed in contact with a sidewall of beverage container  500 , as shown for example in  FIGS. 5 and 6 . In some embodiments, contact surface  174  is flat or planar (see, e.g.,  FIG. 6 ) so as to be placed in facing engagement with a flat wall of a beverage container  500 . However, in some embodiments, contact surface  174  may be curved and may have a concave curvature so as to match the curvature of a beverage container having a curved sidewall. Contact surface  174  may be placed in facing engagement with a sidewall of beverage container  500 . 
     In some embodiments, contact surface  174  of applicator  172  may have an area of 0.5 in 2  to 9 in 2 , 1 in 2  to 8 in 2 , or 1.5 in 2  to 7 in 2 . In some embodiments, the contact surface  174  may have an area of about 3 in 2 . Increasing the area of contact of applicator  172  and beverage container  500  may result in more efficient transfer of ultrasonic energy to the beverage. As a result, nucleation of a beverage may occur more rapidly as a contact area increases, and the amount of energy required to nucleate the beverage may be reduced. This may be particularly important for beverage containers having thick sidewalls, such as glass beverage containers. 
     In some embodiments, applicator  172  may be arranged so as to contact a rear wall  504  of beverage container  500  on support  130 , as shown in  FIGS. 3-6 . In this way, beverage container  500  can be viewed by a consumer during nucleation and applicator  172  does not obscure the consumer&#39;s view of beverage container  500 , and specifically a front sidewall  501  of beverage container  500 , from a front of beverage nucleation device  100 . 
     In some embodiments, beverage nucleation device  100  may be configured to apply ultrasonic energy to beverage container  500  via ultrasonic transducer  170  for a predetermined period of time, for example, 1 to 10 seconds. The amount of time ultrasonic energy is applied to cause nucleation of a beverage may depend upon several factors including the power of the ultrasonic transducer, the frequency of the ultrasonic energy, the material of the applicator, the type of beverage container, and the type of beverage, among other factors as will be appreciated by one skilled in the art. While ultrasonic energy may be applied for a predetermined period of time to induce nucleation of the beverage, it is understood that nucleation of the beverage may continue to occur after ultrasonic energy is no longer applied. In some embodiments, the predetermined period of time is determined based on the type of beverage to be nucleated. In such embodiments, beverage nucleation device  100  may include a sensor  133  configured to detect the type of beverage to be nucleated, such as by detecting a label, barcode, or other identifier of a beverage container, and selecting the predetermined period of time based on the type of beverage container as determined by the sensor. 
     In some embodiments, applicator  172  may be configured to move between a resting position and an operational position. In the resting position, as shown in  FIG. 6 , applicator  172  is spaced from a beverage container  500  arranged on support  130 . In the operational position, applicator  172  is moved toward beverage container  500  so that a contact surface  174  of applicator  172  is placed in facing engagement with a sidewall, such as a rear wall  504 , of beverage container  500 . Applicator  172  may be configured to move a predetermined distance from the resting to the operational state, or the applicator  172  may be configured to move a sufficient distance for applicator  172  to contact beverage container  500 . In such embodiments, applicator  172  may include a sensor  136 , such as a pressure sensor or proximity sensor, configured to determine when applicator  172  contacts beverage container  500 . 
     In some embodiments, beverage nucleation device  100  may additionally include a beverage container holder  140  configured to maintain beverage container  500  in a static position during operation of beverage nucleation device  100 . In some embodiments, container holder  140  may be shaped so as to fit closely to a beverage container, such as by a friction fit. In some embodiments, container holder  140  is in a fixed position and a consumer may insert beverage container into container holder  140  so that container is tightly held by container holder  140 . However, in some embodiments, container holder  140  may be movable and is selectively brought into contact with a beverage container  500  during operation of beverage nucleation device  100 . In some embodiments, container holder  140  may be, for example, a clamp that is movable from an open position for receiving a beverage container, and a closed position for securing the beverage container. Container holder  140  may be manually operated so that a consumer can move container holder  140  from an open to a closed position. Alternatively, container holder  140  may be automated so that once a beverage container is positioned in beverage container receiving area, beverage nucleation device  100  automatically moves container holder  140  to a closed position so that beverage container  500  is secured in a static position for nucleation. 
     In some embodiments, beverage nucleation device  100  includes a beverage container holder  140  having one or more arms  142 ,  144 , as shown for example in  FIGS. 3-6 . Beverage container  500  may be positioned in a space  148  between first and second arms  142 ,  144  on beverage container support  130 . In some embodiments, container holder  140  may include a first arm  142  and a second arm  142 , as shown in  FIGS. 3-6 . First arm  142  is arranged opposite second arm  142  such that first and second arms  142 ,  144  face one another and are separated by a space  148  in which beverage container may be positioned. First and second arms  142 ,  144  are linearly movable along a common axis X (see  FIG. 5 ). First and second arms  142 ,  144  are configured to move towards one another for securing a beverage container  500  therebetween, and are further configured to move away from one another for releasing beverage container  500 . First and second arms  142 ,  144  may be configured to move a predetermined distance for contacting a beverage container  500  positioned in space  148  between first and second arms  142 ,  144 . Alternatively, arms  142 ,  144  may be configured to continue to move toward beverage container  500  until each arm  142 ,  144  contacts beverage container  500 . In such embodiments, arms  142 ,  144  may include a sensor, such as a pressure sensor or proximity sensor configured to determine when arms  142 ,  144  contact beverage container  500 . In this way, container holder  140  may secure beverage containers  500  of different sizes, such as bottles of different diameters. For example, a small or skinny bottle may require the arms  142 ,  144  of container holder  140  to move a further distance than a wider or larger bottle in order for arms  142 ,  144  to contact the beverage container  500 . 
     When beverage nucleation device  100  is not in use, beverage container holder  140  is arranged in a resting position, with first and second arms  142 ,  144  separated from one another by a first distance, as shown in  FIG. 5 . When beverage nucleation device  100  is in use, e.g., when a beverage container  500  is placed on support  130  and actuator  102  is actuated, beverage container holder  140  moves into the operational position. In the operational position, first and second arms  142 ,  144  are in contact with opposing sidewalls  502 ,  503  of beverage container  500  and are separated by a second distance that is smaller than the first distance, as shown in  FIG. 6 . 
     In some embodiments, applicator  172  and beverage container holder  140  may move from the resting to the operational position simultaneously or nearly simultaneously. In some embodiments, beverage container holder  140  may move from resting position to operational position and then subsequently applicator  172  is moved from resting position to operational position. In this way, beverage nucleation device  100  may ensure that beverage container  500  is secured prior to moving applicator  172  into contact with beverage container  500 . 
     In some embodiments, beverage nucleation device  100  includes a control unit  150  for controlling operation of beverage nucleation device  100  and its components. Control unit  150  may be in communication with actuator  102  such that when actuator  102  is operated by a consumer, control unit  150  causes beverage nucleation device  100  to carry out a beverage nucleation process. Control unit  150  may further be in communication with a drive mechanism  155 , and drive mechanism  155  may cause movement of beverage container holder  140  from the resting position to the operational position. Drive mechanism  155  may include an electrical motor or a linear actuator, among others. Drive mechanism  155  may also cause movement of applicator  172  from the resting position to the operational position. Further, drive mechanism  155  may cause movement of gates  138  from resting position to operational position. In some embodiments, beverage container holder  140 , applicator  172 , and/or gates  138  may each have a separate drive mechanism operated by control unit  150 . 
     Control unit  150  may cause ultrasonic transducer  170  to generate ultrasonic energy, and to stop generating and applying ultrasonic energy after a predetermined period of time (e.g., 1 to 10 seconds). 
     Control unit  150  may also control operation of light strip  139  and indicator  160 . As discussed above, light strip  139  is configured to indicate when beverage nucleation device  100  is ready for use. Further, indicator  160  is configured to indicate the status or progress of a beverage nucleation process, as shown for example in  FIG. 8 . In one embodiment, indicator  160  includes one or more lights  162 . Lights  162  may include light emitting diodes (LEDs), incandescent lamps, compact fluorescent lamps, or halogen lamps, among other types of lights. Lights  162  may be turned off (not illuminated), and may illuminate once the nucleation process is complete in order to indicate that the beverage is ready to be consumed. 
     In some embodiments, indicator  160  may include a color transition in which lights  162  are originally illuminated in a first color and lights  162  transition to a second color during the nucleation process. Thus, lights  162  may be illuminated in a first color at the outset of the beverage nucleation process and lights  162  may gradually change or transition to a second color that differs from the first color during the nucleation process. For example, lights  162  may be illuminated in a white color and may gradually transition from white to blue, such that when all lights  162  are illuminated in the blue color, the nucleation process is complete. In a further example, all lights  162  may be illuminated in a white color  162 A, and some lights may turn blue  162 B during nucleation process, with an increasing number of lights turning blue as the process progresses, until all lights are blue. A color transition from white to blue is illustrative, and any color transition may be used (e.g., yellow to green, red to purple, etc.). The rate of progress of the color transition may be based on the predetermined time for nucleation. 
     In some embodiments, indicator  160  may include a display  161 , as shown for example in  FIG. 9 . Display  161  may be, for example, a liquid crystal display (LCD), a light emitting diode (LED) display, or an organic LED (OLED) display, among other types of displays  161 . Display  161  may operate in the same manner as lights  162  and thus may display a color transition in which the display or portions thereof illuminate in a first color and transition to a second color during the beverage nucleation process. 
     In some embodiments, display  161  may show a plurality of first icons  164  that transition to second icons  166  during the beverage nucleation process, referred to as an icon transition. For example, first icons  164  may include circles or dots as shown in  FIG. 9 . As beverage nucleation process progresses, first icons  164  may transition from circles or dots to a second icon  166  that differs from the first icon, such as a snowflake. Thus, at the outset of beverage nucleation only first icons  164  are shown, during nucleation both first icons  164  and second icons  166  are shown (or a transitional icon  165  having features of both first and second icons  164 ,  166  may be shown), with an increasing number of second icons  166  being shown as nucleation progresses. Finally, at completion of nucleation, all icons are shown as second icons  166 . 
     In some embodiments, indicator  160  may show or provide both a color transition and an icon transition to illustrate the progress of the nucleation process. For example, icons may be shown as white circles at the beginning of the nucleation process and the icons may transition to blue snowflakes at the end of the nucleation process. 
     In some embodiments, indicator  160  may alternatively or additionally include a timer that shows a countdown of the time remaining in the nucleation process. For example, nucleation may take 10 seconds and timer may display “10 seconds” and count down (e.g., 9 seconds, 8 seconds, 7 seconds, etc.) until nucleation is complete. 
     In some embodiments, beverage container  500  for use with beverage nucleation device  100  may include a label  510  as shown in  FIG. 10 . Label  510  may indicate when beverage container  500  (and beverage contained therein) is at a suitable temperature for nucleation, such as a temperature at or below a freezing point of the beverage. Label  510  may be, for example, a thermochromic label that is configured to change color when a beverage within the container is at or below the freezing point of the beverage. In this way, a consumer may easily determine that a particular beverage is ready for nucleation by viewing the color of the thermochromic label. 
     In such embodiments, beverage nucleation device  100  may include a label reader  190  configured to detect or read label  510  to determine if beverage container  500  is at a temperature suitable for nucleation. Label reader  190  may be, for example, an optical sensor, such as a camera or the like, configured to detect a color of label  510 . If label reader  190  determines that beverage container  500  is at a temperature suitable for nucleation based on a color of label  510 , beverage nucleation device  100  may automatically begin nucleation of beverage within beverage container  500 , or may allow a consumer to begin nucleation by operating actuator  102 . However, if label reader  190  determines that beverage container  500  is not at a temperature suitable for nucleation, beverage nucleation device  100  may not start the nucleation process even if actuator  102  is operated. Beverage nucleation device  100  may further display an error message or audible alert to indicate to the consumer that the selected beverage container  500  is not ready to be nucleated. 
     An exemplary method of nucleating a beverage using a beverage nucleation device  1100  is shown for example in  FIG. 11 . A beverage container containing a supercooled beverage may be secured in a beverage nucleation device  1110 . Once secured in the beverage nucleation device, the beverage container may be contacted by the applicator of the beverage nucleation device  1120 . Ultrasonic energy can then be applied to the beverage container via the applicator to cause nucleation of the supercooled beverage  1130 . 
     An exemplary method of using a beverage nucleation device as described herein to nucleate a beverage  1200  is shown in  FIG. 12 . In operation, a consumer may retrieve a beverage container containing a supercooled beverage, such as from a cooler or refrigerator for storing beverages at or below their freezing points. Consumer may place the beverage container in the beverage nucleation device  1210 , such as on support of the beverage nucleation device within a beverage container receiving area of beverage nucleation device. Consumer may operate the actuator  1220  in order to begin the nucleation process. For example, actuator may be a push-button, and consumer may press the push-button. Upon operating actuator, beverage container may be secured on support by a beverage container holder  1230 . Beverage container holder may include a pair of arms that move from a resting position to an operational position in which the pair of arms contacts opposing sidewalls of the beverage container so as to hold beverage container in a static position. Applicator of ultrasound transducer is moved from a resting position into an operational position in which applicator is in contact with a sidewall of a beverage container, such as a rear sidewall, and ultrasound is applied to beverage container via the applicator to cause nucleation of the beverage  1240 . Applicator may be moved into contact with beverage container at a same time as container holder is moved into the operational position. With applicator in contact with beverage container, ultrasound may be generated by an ultrasonic transducer and applied for a predetermined period of time (e.g., 1 to 10 seconds). After the predetermined period of time elapses, the beverage nucleation device may cease generation and application of ultrasonic energy via ultrasonic transducer  1250 . Applicator may be removed from contact with beverage container, and similarly beverage container holder may move from operational position to resting position so that beverage container is no longer held or supported by beverage container holder  1260 . Applicator and container holder may be moved at the same time or in succession. Beverage container containing a slush beverage may then be removed from beverage nucleation device by the consumer.

Software and data transferred via communication interface  1324  may be in the form of signals, which may be electronic, electromagnetic, optical, or other signals capable of being received by communication interface  1324 . These signals may be provided to communication interface  1324  via a communication path  1326 . Communication path  1326  carries signals and may be implemented using wire or cable, fiber optics, a phone line, a cellular phone link, an RF link or other communication channels.
