Definitions

  • the present invention relates to an effervescent-beverage pouring device.
  • the foam is preferably a fine one so as to delay the escape of the carbon dioxide from the drink and the oxidation of the drink. Further, the fine foam can keep the drink delicious.
  • beer stored in kegs is poured into containers by a specialized server and then provided to the customers.
  • expert skill is required for various operations such as adjusting the angle of the container when pouring the beer, the opening degree of the stopcock, the amount poured, and/or the gas pressure and other various operations.
  • Patent Literature 1 discloses a tap for pouring an effervescent-beverage in which an ultrasonic wave generating element is embedded in the discharge outlet.
  • Patent Literature 2 discloses a pouring device for beer used attached to a pitcher. This device comprises an ultrasonic wave element set at a bottom side of a cross-section of a nozzle.
  • Patent Literature 3 discloses a pouring device for an effervescent-beverage used attached to a pitcher or other portable container. This device comprises a vibrating device for imparting vibration to a drink flowing through a passage inside the device.
  • an ultrasonic wave generating element is used for a pitcher, can, bottle, or other portable container in which a drink is poured at a slow flow rate by mainly gravity, a fine foam will be sufficiently produced, but if an ultrasonic wave generating element is used for a drink server in which a drink is poured at a fast flow rate, there is a possibility that a fine foam will not be sufficiently produced,
  • the present invention has as its object the provision of an effervescent-beverage pouring device able to produce fine foam.
  • One embodiment of the present disclosure is an effervescent-beverage pouring device comprising a first tube for supplying the effervescent-beverage, a second tube harder than the first tube and to be inserted inside of the first tube, and an element for applying ultrasonic waves to the first tube at a position where the first tube and the second tube are superposed.
  • the inventors discovered that by inserting a second tube into a first tube to thereby form a constricted part with a small passage cross-sectional area and apply ultrasonic waves to that constricted part, it is possible to transmit the ultrasonic waves to the passage as a whole and therefore possible to produce a fine foam.
  • ultrasonic waves are applied to the above such constricted part combining the first tube and the second tube.
  • the inventors discovered that if transmitting vibration to a drink (that is, a liquid), by transmitting the vibration from the second tube, which is harder than the first tube, compared to when transmitting vibration from the first tube, it is possible to efficiently transmit vibration to the drink without allowing the vibration to be absorbed. Therefore, it is possible to produce fine foam.
