Definitions

  • the present invention relates to dispensing beverages. More specifically, the present invention relates to preparing beverages with a base liquid and an additive.
  • a beverage dispenser is a device that prepares a beverage from one or more beverage sources.
  • beverage sources that include concentrates and/or powders are mixed with a liquid (e.g., water) to prepare the beverage.
  • a liquid e.g., water
  • Some types of dispensers dispense relatively cold beverages (e.g., soft drinks), requiring concentrates, while other types of dispensers dispense relatively hot beverages (e.g., coffees, teas, and hot chocolates), such as using powders.
  • a traditional cold-beverage dispenser is disclosed in U.S. Pat. No. 5,960,997.
  • the dispenser dispenses a base beverage, such as a soft drink syrup, and an agent for diluting that syrup into a cup.
  • the dispenser also dispenses a flavoring into the cup simultaneously with and throughout the dispensing of the base beverage so as to maintain a constant ratio between the volume of the base beverage and the volume of the flavoring. While keeping the ratio constant, this results in a less than ideal mixing.
  • a traditional hot-beverage dispenser is disclosed in U.S. Pat. No. 6,419,120. This dispenser has multiple flavoring dispensers and prepares a flavored beverage by dispensing a base powder, water, and one or more of the flavorings into a cup.
  • a dispenser and a dispensing method are therefore needed to provide improved mixing of an additive with a base liquid during preparation of a flavored beverage
  • the present invention relates to beverage dispensers and dispensing methods that provide improved mixing of one or more additives (e.g., flavorings) with a base liquid. For instance, by varying the dispensed proportion of the additive, the mixing is improved as the base is dispensed. Varying the ratio of additive to base liquid is especially advantageous, for example, when the ratio is varied, preferably with a reduced amount of additive compared to base, at one or both of the beginning and end of the beverage dispensing.
  • a dispenser constructed according to the invention can deliver a very elevated level of flavor mixing, whether the beverage is hot or cold.

  • the dispensing of the additive is commenced after commencing the dispensing of the base liquid.
  • the dispensing of the base liquid is commenced at least about 1 second before commencing the dispensing of the additive.
  • the dispensing of the base liquid can be stopped at the same time as or later than, but preferably not earlier than, the stopping of the dispensing of the flowable additive.
  • the dispensing of the base liquid is preferably stopped after the dispensing of the flowable additive is stopped for varying the additive concentration in the base liquid after the additive dispensing is stopped.
  • the dispensing of the base liquid can be stopped after a stopping time period after stopping the dispensing of the additive, in which the stopping time period is proportional to the duration of the additive dispensing.
  • the dispensing of the base liquid and the additive can be controlled by operating a dispensing control.
  • the base liquid and the additive can be dispensed for predetermined time periods in response to operation of the dispensing control.
  • the base liquid can be automatically dispensed for a predetermined period longer than the additive after operation of the dispensing control.
  • the additive is preferably dispensed during the dispensing of the base liquid to mix with the base liquid.
  • the additive can be mixed in the base liquid in a relative concentration typically between 1:1000 to 1:25 volume of additive to base liquid.

Preferably, this concentration is from about 0.1 mL additive per 250 mL base liquid to as much as about 2 mL additive per 250 mL base liquid for coffee products, and from about 5 mL and 10 mL of additive per 250 mL base liquid in nutritional supplements or texture improving compounds.
  • concentration of additive in base liquid will depend on the types of additive and base liquid and beverage to be prepared and other factors known to those of ordinary skill in the art.
  • controller 145 causes the additive to be dispensed continuously into container 150 , i.e., dispensed in a continuous stream throughout the duration of additive dispensing.
  • Controller 145 can be configured to continuously dispense the additive based on instructions that are stored in the storage media and/or instructions that are received from an user via a user interface (e.g., based on the “push and hold” operation previously described herein).
  • controller 145 causes the additive to be dispensed intermittently or “pulsed” into container 150 .
  • Controller 145 can be configured to pulse the additive based on instructions that are stored in the storage media, e.g., instructions indicating a number of pulses, the durations of each pulse, the durations between each pulse, the start time of pulsing relative to start time of base liquid dispensation, and the end time of pulsing relative to start time and/or end time of base liquid dispensation.
  • the dispensation of the base liquid can be paused during pulsing, i.e., can terminate prior to additive pulsing, and recommence after additive pulsing.
  • the base liquid is dispensed throughout additive pulsing so as to enhance mixing between the base liquid and the additive.
  • controller 145 can cause the additive to be pulsed based on instructions that are received from a user via a user interface (e.g., based on the “push” operation previously described herein).
  • the features of the pulsing e.g., number of pulses, durations, durations between, start times, and stop times
  • the user inputs such as the particular beverage and additive(s) selected.
  • controller 145 causes the dispensation of the additive to terminate ( 360 in FIG. 3 ) and the dispensation of the base liquid to terminate ( 370 in FIG. 3 ).
  • the controller controls the dispensation periods so that the base liquid is dispensed for a time period T 1 and the additive is dispensed for a time period T 2 , in which time period T 2 commences after the start of time period T 1 and terminates not later than the termination of time period T 1 .
  • the additive dispensing terminates before the termination of the base liquid dispensing (i.e., the time period T 2 terminates before the termination of time period T 1 ) so as to enhance mixing between the additive and the base liquid and prevent or inhibit splashing of the additive from the surface of the dispensed beverage.
  • the additive dispensation will terminate within about 2 seconds of the termination of the base liquid dispensation.
  • the base liquid dispensation can be terminated at a time period (the “stopping time period”) after the termination of the additive dispensing. The duration of that time period can be proportional to the additive dispensation time period T 2 .
  • controller 145 controls dispensation of the base liquid so that, during at least a portion of the period of that dispensation (preferably, during a terminal portion of that period), the base liquid is whipped by whipper 176 prior to being dispensed into container 150 .
  • controller 145 can cause the base liquid to be whipped by whipper 176 towards the end of the dispensation period of the base liquid so as to provide a layer of foam on the liquid beverage in container 150 (e.g., a layer of foam for a coffee beverage, such as a cappuccino or a latte).
  • the whipping period can be based on instructions in the storage media and/or can be determined based on instructions received from an operator via a user interface.
  • controller 145 can cause one or more additives to be dispensed into container 150 ( 340 in FIG. 3 ).
  • controller 145 and/or a user via a user interface can control the dispensation features of each additive, e.g., the start time of dispensation, the end time of dispensation, etc.
  • the start times and the end times at which two or more additives are dispensed overlap, so that the additives are dispensed simultaneously, thereby enhancing blending among the additives.
  • the start times and/or the end times can be different, so as to prevent or inhibit cross-contamination that could occur during simultaneous dispensation.
  • the disclosed beverage dispensers have been described with respect to beverage components that are stored in “storage chambers” and “additives” that are stored in “containers,” the disclosed beverage dispensers are not limited to such storage media and can be suitably modified so as to store the beverage components and/or the additives in other types of storage media, such as, but not limited to, bags, cartons, cylinders, hoppers, and the like.
  • references herein to storage chambers and containers are for convenience only, and are to be understood more generally as references to storage media for storing beverage components and additives.
