Definitions

  • the present invention refers to an apparatus for enriching a liquid with gas, e.g. for carbonation of a liquid, for example an apparatus for in-line carbonation of water. Further, the present invention refers to a method for dispensing gas enriched liquid.
  • the gas which is used to enrich the respective liquids is typically carbon dioxide (CO 2 ) which is introduced into a beverage container, usually a bottle, via a spout or opening of the container.
  • CO 2 carbon dioxide
  • Examples of apparatuses for enriching gas are for example known from US 2021/0283558 A1 , US 572 779 A or WO 2015/175244 A2 .
  • a further example of such an apparatus is known from EP 0 000 813 B1 in which water may be carbonated in a water-filled pressure vessel into which pressurized CO 2 is introduced.
  • Gas enriched water may be dispensed from the pressure vessel by introducing further (not gas enriched) water into the pressure vessel with a higher pressure than the gas enriched water in the pressure vessel, e.g. due to gravitational force.
  • DE 10 2015 213 843 A1 and US 5,124,088 A both disclose devices for carbonation of water in which pressurized CO 2 is introduced into a water-filled tank. Gas enriched water may be dispensed from this tank by means of the pressure applied by the CO 2 introduced into the tank.
  • These known devices have in common that the amount of gas enriched water which may be dispensed is limited to the volume of the vessel or tank in which the water is carbonated by introducing pressurized CO 2 .
  • EP 3 107 645 B1 discloses a system for in-line carbonation of water.
  • water is fed into a main inlet of a mixing venturi nozzle by means of a pump, wherein pressurized CO 2 is fed to a side inlet of the venturi nozzle.
  • pressurized CO 2 is fed to a side inlet of the venturi nozzle.
  • This allows dispensing larger amounts of gas enriched water as the pump is operated and pressurized CO 2 is fed to the venturi nozzle.
  • the operation of the pump requires an electrical power supply.
  • the present invention is based on the idea of using gas enriched liquid in an inline mixer to which gas and liquid are fed, while the pressure of the gas used for enriching (e.g. carbonation) is further used for feeding the liquid from a tank to the inline mixer unit.
  • This allows operation of the apparatus without requiring electronic components and without an electronic power source.
  • the apparatus has the benefit of being able to dispense a large amount of gas enriched liquid while being operable without connection to a water line. This makes it possible to provide the apparatus as a mobile or portable device. Still further, the relatively simple mechanical operation of the apparatus results in a high reliability.
  • the apparatus for enriching a liquid with gas may substantially comprise a refillable liquid tank, a gas supply port and a mixer unit.
  • the liquid tank may have a liquid outlet and may be releasably locked in the apparatus allowing replacement or refilling of the liquid tank.
  • the mixer unit may have a liquid inlet connectable with the liquid outlet, a mixer gas inlet connectable with a gas supply port and an gas enriched liquid outlet, e.g. with a tap, for dispensing gas enriched liquid.
  • the mixer unit may be an inline mixer for continuously mixing liquid and gas as they flow through the mixer unit.
  • the liquid tank may comprise a tank gas inlet connectable to the gas supply port.
  • the gas supply port is connectable to a gas tank, e.g. a CO 2 bottle.
  • the liquid inlet of the mixer unit is connected with the liquid outlet of the liquid tank via a line which may comprise a check valve and/or blocking means.
  • the mixer gas inlet may be connected with the gas supply port via a line which may comprise a pressure regulator, a control valve, a check valve and/or blocking means.
  • the tank gas inlet may be connected with the gas supply port via a line which may comprise a pressure regulator, a control valve, a check valve and/or blocking means.
  • the connections to the liquid tank may be made releasable permitting easy detachment of the liquid tank for refilling.
  • the gas supply port may permit easy attachment and detachment of a gas tank, like a gas bottle.
  • the apparatus comprises a gas reservoir connectable to a tank gas outlet of the liquid tank.
  • the gas reservoir is a container suitable for temporarily storing pressurized gas.
  • the gas reservoir may comprise a reservoir gas inlet, a reservoir gas outlet and a reservoir space in communication with the reservoir gas inlet and the reservoir gas outlet.
  • the reservoir space may serve to receive pressurized gas fed from the liquid tank to the gas reservoir in order to store the pressurized gas and to permit further use of the pressurized gas at a later point in time, e.g. during a subsequent operation.
  • the gas reservoir may further comprise an internal compartment sealed from the reservoir space by an elastically deformable membrane. This may contribute in storing more pressurized gas in the gas reservoir.
  • the provision of the gas reservoir is based on the idea that feeding liquid from the liquid tank to the mixer unit by means of pressurized gas, results in the liquid tank being substantially filled with the pressurized gas as the liquid tank gets empty.
  • the pressurized gas may be simply dispensed into the ambient air when refilling the liquid tank.
  • the gas reservoir may be connected to the tank gas outlet via a valve and/or a blocking device to be selectively closed at least during dispensing gas enriched liquid and to be selectively opened at least at the beginning of a refilling step.
  • a refilling step may initially comprise unlocking of the liquid tank form the apparatus or its housing, thereby blocking or disconnecting the gas supply port from the tank gas inlet and permitting a fluid communication between the liquid tank and the gas reservoir.
  • the liquid tank may comprise a lid detachable from the liquid tank for refilling, wherein a fluid connection between the liquid tank and the gas reservoir is blocked when the lid is air-tight sealed to the liquid tank and when the lid is fully removed from the liquid tank, and wherein the fluid connection between the liquid tank and the gas reservoir is established when the lid is partially lifted from the liquid tank.
  • the liquid tank comprises an annular sealing surface for sealing abutment with an annular counter sealing surface of the lid wherein the tank gas outlet is arranged in the counter sealing surface.
  • the tank gas outlet is closed by the sealing surface of the liquid tank if the sealing surface of the liquid tank abuts the counter sealing surface of the lid and automatically opens if the counter sealing surface of the lid is lifted from the sealing surface of the liquid tank.
  • the lid may be attached to the liquid tank by means of a bayonet coupling permitting in one relative position of the lid relative to the liquid tank that the lid is slightly lifted from the liquid tank due to the internal pressure of the gas in the liquid tank, while still retaining the lid on the liquid tank. This may occur automatically when unlocking the liquid tank from the apparatus prior to exchanging or refilling the liquid tank.
  • the gas reservoir may comprise a reservoir gas outlet connectable to the tank gas inlet and/or to an optional further tank gas inlet.
  • the connection between the gas reservoir and the liquid tank is established automatically during or after locking the liquid tank in the apparatus.
  • the tank gas inlet and/or to an optional further tank gas inlet comprises a blocking valve which is opened if the sealing surface of the liquid tank abuts the counter sealing surface of the lid, thereby connecting the gas reservoir with the interior of the liquid tank.
  • a second additional or alternative option for using the pressurized gas retained in the gas reservoir is to feed the gas into the inline mixer unit for enriching the liquid.
  • This may include use of the pressurized gas for the inline gas enriching during dispensing gas enriched liquid and/or the use of the pressurized gas as a gas enriching booster in addition to the pressurized gas fed to the mixer unit from the gas supply port, i.e. for increasing the degree of gas enrichment.
  • the gas reservoir comprises a reservoir gas outlet connectable to the mixer gas inlet and/or to a further mixer gas inlet.
  • the mixer gas inlet and/or the further mixer gas inlet may comprise a blocking valve operable by a user operated switch button.
  • a first a pressure regulator is provided between the gas supply port and the tank gas inlet, wherein a second a pressure regulator is provided between the gas supply port and the mixer gas inlet wherein the first pressure regulator is set to a higher pressure than the pressure of the second pressure regulator.
  • the first pressure regulator may be set to about 4.5 bar while the second pressure regulator may be set to about 4.0 bar.
  • the difference between the pressure to which the pressure regulators are set may be above 0.1 bar, e.g. at least 0.2 bar, preferably between 0.3 bar and 2.5 bar.
  • the pressure to which the first pressure regulator is set may be above 1.5 bar, e.g. at least 2.0 bar, preferably between 3.0 bar and 7.0 bar.
  • the apparatus may further comprise a filter provided in the liquid outlet or interposed between the liquid outlet and the mixer liquid inlet.
  • the filter is a replaceable filter cartridge for cleaning the liquid fed from the liquid tank to the inline mixer unit.
  • the apparatus may comprise a housing encasing, at least partially, the refillable liquid tank, the gas supply port, the mixer unit and/or the gas reservoir.
  • the housing may comprise latching means for releasably locking the liquid tank and/or a gas tank into the housing.
  • a tap for dispensing gas enriched liquid from the gas enriched liquid outlet and, optionally, a user operable switch button may be accessible from outside the housing to allow operation of the apparatus.
  • a user may dispense gas enriched liquid from the apparatus simply by opening the tap such that gas enriched liquid is dispensed until either the liquid tank or the gas tank runs empty.
  • An optional booster switch button may be used to increase the degree of gas enrichment by feeding additional pressurized gas and/or gas with higher pressure into the inline mixer unit.
  • a method for producing and dispensing gas enriched liquid comprises the steps of: providing liquid in a refillable liquid tank, providing gas in a gas tank, introducing gas from the gas tank into the liquid tank, thereby dispensing liquid from the liquid tank to an inline mixer unit provided downstream of the liquid tank, introducing gas from the gas tank into the mixer unit, thereby enriching the liquid with gas, and dispensing gas enriched liquid, e.g. by operating a dispensing tap.
