Definitions

  • the present invention relates to a portable and stand-alone device suitable for dispensing foamed liquids such as beverages with a foamed 'head'. It is useful, for example, in dispensing foamed cold-brew coffee, cold tea, novelty cocktails and other cold beverages which would otherwise be served flat. It is also useful for the dispensing of foamed dairy products such as a cream and milk.
  • US2013270722 describes a carbonation chamber in which gas and liquid are mixed axially in response to a metering member.
  • Other approaches to ensuring the carbon-dioxide and liquid are intimately mixed have been described in inter alia WO2007112892, DE10160397,
  • DE202017005461U1 describes an in-line dispensing nozzle system comprising a pipe section and a tapered outlet spout.
  • the spout is characterized in that, between the inlet side of the pipe and the outlet of the spout, there is provided a component for mixing the beverage and a gas.
  • the system can be used to produce nitrogenized coffee or beer.
  • a portable device for dispensing foamed liquids characterised by comprising:
  • a foam-dispensing nozzle assembly including a dispensing unit comprising a means for creating a laminar flow of the foamed mixture and/or one or more gas— liquid mixing element(s) located upstream thereof and
  • the container is an elongate flask with a threaded end which may be attached to a lid on which the reservoir, and/or the dispensing unit and/or the trigger may be mounted.
  • the lid may further include a pressure-release valve to ensure the device is not over-pressurised.
  • the container may be wholly or partially transparent enabling the user to determine the level of liquid within. If desired, the container may be double-walled akin to a vacuum flask thereby enabling the liquid contents to be maintained warmer or colder than ambient temperature.
  • the reservoir is attached to the container directly or via the lid; for example by means of a threaded coupling optionally provided with an O-ring seal or the like.
  • the reservoir can be detached from the device as required for the purpose of refilling or re- pressurising.
  • the reservoir comprises an outer housing capable of withstanding pressure and adapted to receive one or more separate cartridges of pressurised gas which after use can then be recycled or simply thrown away.
  • cartridges will comprise a piercing zone of weakness to release the gas into the container when the housing and/or cartridge is connected to the lid.
  • this piercing means will create a fluid communication between the cartridge and container and will optionally include a non-return pressure-valve which will close the line of communication when the internal pressure of the container and the cartridge are equalised.
  • the pressure in the container may be topped-up as required; multiple cartridges of lower pressure applied in series to create an overall higher pressure within the container or the device transported without the cartridge or housing being attached. In this latter case, the housing may then simply be replaced by a screw-cap.
  • the piercing zone of weakness is adapted to be resealable when the cartridge is detached from the container or lid.
  • the reservoir may be provided with a pressure regulation device to ensure that the container is not over-pressurised and/or to ensure that the same pressure is applied to the container in each dispensing cycle. By this means a consistency in the quality of the foam at the outlet is maintained for each dispensing.
  • the compressed gas employed in the reservoir or cartridge is one which has a low solubility in the liquid contents of the container.
  • examples include air, nitrogen, nitrous oxide carbon dioxide or mixtures thereof.
  • the gas employed is nitrogen, air or a mixture thereof.
  • the foam-dispensing nozzle assembly in one embodiment this is hollow and is attached to the lid by means of a screw-thread.
  • the dispensing unit enables the dispensing of the foamed liquid from the nozzle assembly to a suitable external vessel, typically a glass or cup. It generally comprises a suitable outlet, or nozzle, by which the foamed liquid can exit the nozzle assembly.
  • the nozzle assembly will comprise a housing tapered in the direction of its outlet and will comprise a means for creating a laminar flow of the foamed mixture and/or one or more gas-liquid mixing element(s) located upstream thereof.
  • the means for creating the laminar flow will suitably comprise a perforated element enabling multiple streams of the gas/liquid mixture to be dispensed as a foam under conditions of laminar flow.
  • a perforated element enabling multiple streams of the gas/liquid mixture to be dispensed as a foam under conditions of laminar flow.
  • this perforated element will be located immediately upstream of the nozzle by means of a seating which enables it to be easily removed for cleaning.
  • this element may be a perforated disc of metal, plastic or ceramic with associated perforations large enough to facilitate laminar flow but small enough to prevent particulate matter of significant size to exit the device.
  • the gas-liquid mixing element(s) in one embodiment these may comprise one or more Venturi mixers where acceleration of liquid flow through a hollow tubing (e.g.
  • the elements may comprise Coanda mixers.
  • these elements may comprise one or more jet-mixing elements akin to an aerator of the type used in household taps to aerate or mix hot and cold water streams.
  • such element(s) comprise hollow perforated plastic inserts which are arranged in series along the axis of liquid flow and located in the body of the assembly thereby making them easily removable for cleaning or replacement purposes.
  • the gas-liquid mixer(s) and means for creating the laminar flow are located in separate sub-components of the foam-dispensing nozzle assembly which are adapted to connect one another; e.g. by means of a screw thread or snap-fit.
  • the device may include a particle filter between the container and the foam- dispensing nozzle assembly to filter out coffee grounds or similar sediments found in other beverages.
  • the trigger mechanism is one which conveniently is hand-operated, for example by squeezing, and operable to control ingress of the gas and/or liquid into the dispensing unit and/or egress of the gas-liquid mixture from the foam-dispensing assembly.
  • the device of the present invention can be used for dispensing any of the beverages described in the preamble above. This list is provided for exemplification purposes only and therefore not be regarded as exhaustive.
  • the device can also be used to rejuvenate flat beer and the like.
  • the device is especially useful for dispensing cold- brewed coffee; preferably where the average particle size of the fines within the coffee brew are less than a hundred microns.
  • foamed tea, coffee or other cold beverages which have been augmented with various flavourings; for example with spices, herbs or the like which have been introduced into the container along with the beverage or one of its components before the device is used.
  • foamed dairy products such as foamed cream or milk can easily be produced when the dispensing nozzle assembly is used separately; especially using nitrogen gas which has previously been problematic. This makes the device and the foam-dispensing nozzle assembly very environmentally friendly and particularly suitable for use in coffee shops and other retail outlets selling foamed dairy drinks.
  • the device of the present invention will now be exemplified by the attached Figure which shows a sectional view of a cold-brew coffer dispenser whose components are manufactured out of stainless steel.
  • 1 comprises a threaded flask containing a high-quality filtered cold-brewed coffee (fines ⁇ 25 microns). Its nozzle assembly 7 is generally tapered towards its top and attached by a screw-thread/O ring arrangement (not shown) to lid 2. Attached to 2 by a further threaded connector (also not shown) is housing 3 which is adapted to be a snug-fit for a generally tubular metal cartridge 4 containing nitrous oxide or nitrogen gas at high pressure.
  • the threaded connector includes a needle tube which has pierced a piercing zone of weakness on 4 enabling pressurised gas to flow into 1 until the pressures are equalised.
  • trigger 5 which when actuated by squeezing enables pads to cease bearing on the orifices in release valve 8 comprising a banjo fitting screwed into sealing adapter 6.
  • 6 is screwed into nozzle assembly 7 which may include a perforated plate, flow-directing elements and a tape aerator element of the type described above (not shown).
