Definitions

  • the present invention relates to a cooling device, a keg in combination with the cooling device and a method of using the cooling device.
  • assemblies for dispensing beverages from kegs into glasses e.g. draught beer dispensing assemblies at pubs or bars, are widely known and used.
  • DraughtMasterTM a professional draught beer system
  • DraughtMasterTM comprising a beverage dispensing system and a chill chamber in which the replaceable keg or pack containing carbonate beer is received.
  • the keg or pack containing carbonated beer comprises a flexible bottle or bag, which is exposed to an elevated pressure from the outside for dispensing the beer.
  • mains supply of 240 V AC need be supplied to an electrically powered compressor generating and maintaining the pressure.
  • the mains supply is needed to generate and provide cooling of the keg from the chill chamber.
  • Self-chilling vessels are based mainly on two different principles, where the first principle uses a closed system separated from the product to be cooled and upon activation initiates an endothermic reaction, which cools the product.
  • US Patent No. 6,266,879 and US Patent No. 6,178,753 describe containers based on this principle.
  • the second principle is based on a closed two-chamber system separated from the product to be cooled, where one chamber comprises an evaporation unit and the second chamber comprises an absorbing unit. When a valve is opened between the two chambers a drop-in pressure causes fluid to evaporate from the evaporation chamber and thereby removing heat from the evaporator. A heat removing material in the second chamber absorbs heat of vaporisation.
  • US Patent No. 6,829,902 describes a self-cooling can based on the phase-change principle.
  • a drawback related to self-chilling vessels designed according to the prior art is the need of specially designed containers which containers comprise the cooling elements inside.
  • the need of specially made containers with certain pressurised cavities with specific materials inside makes the manufacturing process very expensive.
  • thermoelectric cooling device from which a wall assembly extends, said wall assembly being configured to retain a beverage in use.
  • thermoelectric device With the solution mentioned above, it is possible to cool a standard beverage can without special measures.
  • the need for electricity to supply the thermoelectric device with electrical power dramatically limits the use of such holder since either the electricity need be provided from a battery or from an external power supply source, e.g. a mains supply.
  • a cooling device uses evaporation of a cooling fluid and has a cooling mantle fitting around the outside of a drinks container made of a material which material holds the cooling fluid.
  • the cooling fluid is fed to the cooling mantle from a cooling fluid reservoir via flow openings in the mantle.
  • the level and timing of the cooling is controlled via a dosing element which dosing element controls the transfer of the cooling fluid from the cooling reservoir to the cooling mantle.
  • the cooling device has hangers which hangers allow the cooling device to be suspended in free air.
  • a drinks container is known.
  • the container is an evaporatively cooled drinks container especially for a motor cyclist, a runner or a mountain biker.
  • the drinks container has a neoprene casing absorbing fluid for cooling and provides insulation for contents with colour change temperature indication.
  • a dispensing device for dispensing carbonated beverages bottled in plastic or other flexible packaging material is known.
  • the dispensing device has pump which pump applies fluid pressure to enable collapse of a flexible container when a valve is opened to dispense beverage from the container.
  • no efficient cooling of the carbonated beverages bottled in plastic be the case.
  • US 5240144 discloses an apparatus for dispensing of beverages contained in deformable bottles, particularly family-size conventional PET bottles of more than one brand or taste.
  • the apparatus comprises a housing with one or more beverage dispensing valves at the outside, an openable lid, and one or more pressure vessels with openable lid(s) thereinside.
  • Each pressure vessel is configured to receive one or more of the bottle(s) in an upright position.
  • a fitting is mountable to the bottle(s), and is extended by a conduit leading to the respective dispensing valve(s). Air pressure introduced into the vessel(s) cause the squeezing of the bottle(s) thereunder following discharge of the contents of the respective bottle(s) through the dispensing valve.
  • no efficient cooling of the bottles be the case.
  • a beverage such as beer and/or a soft drink
  • a beverage served in a glass at a temperature lower than the surrounding temperature of 20 - 25 degrees, typically the preferred temperature of the beer is 5°-7° C.
  • beer supplied from the keg received in the cooling device is cooled to the preferred temperature of 5°-7° C.
  • Such cooling device provides the advantage that the beverage from the keg is dispensed at the desired temperature, and accordingly user satisfaction when drinking the beer is well.
  • a requirement in a competitive world is that such a cooling device need to be user friendly to operate and constituted of simple and easy manufactureable parts.
  • cooling device should only be supplied with a fluid and/or elements for the cooling which is easy to buy or already present in the household or available in the neighbourhood area.
  • the cooling device should be applicable outside the home e.g. on a picnic or on other places outside the house, e.g. in the garden, on the terrace, on the beach or on a primitive camping site where any electrical supply is different to obtain but where there is access to tap water.
  • the cooling device should be able to be operated as stand-alone equipment only with the need to continuously supply tap water, which is needed to maintain a pressure on a collapsible keg - with e.g. beer - received within the cooling device.
  • a cooling device for containing a collapsible beverage keg to be cooled to a temperature of e.g. 5°-7° C the cooling device comprising:
  • cooling device it is further being provided with a one-way release valve type for releasing any captured air from within the cooling device, the valve being positioned at the container.
  • the thermally insulating container being made of double walls, alternatively of a foamed lightweight material.
  • the keg being a plastic bag, preferably made of polypropylene and/or polyethylene.
  • the lid being connected to the housing through a hinged connection or through a bayonet coupling and optionally the connector comprising a quick release snap fit connector and/or a valve for controlling the tap water.
  • the beverage in the keg comprises beer such as carbonised beer.
  • the method of cooling the keg may comprise the step of
  • the cooling device can be produced at a low cost and requires no hazardous substances in order to operate, i.e. only ice or slush ice and tap water are consumed which make the cooling device environmentally friendly and suitable for disposable systems, since no hazardous substance are left over in the interior, i.e. on the inner surfaces of the cooling device.
  • Figs. 1a, 1b and 1c show a first embodiment of a cooling device according to the present invention in various stages during its operation from an initial situation to the cooling device in operation for dispensing beer at the desired temperature.
  • Fig. 1a is a cross sectional view of the cooling device designated the reference numeral 10 prior to use.
  • the cooling device 10 serves the purpose of cooling any beer present in a keg 12 to a temperature of e.g. 5°-7° C.
  • the cooling device 10 comprises a thermally insulating container 14, which container 14 comprises a bottom wall 18 as a base portion on which the keg 12 is positioned.
  • the thermally insulating container 14 is preferably made of a foamed lightweight material.
  • An outer wall 20 extends upwardly from the bottom wall 18 and surrounds the keg 12 and defines an upper open end of the container 14.
  • a lid 22 is mounted on top of the upper open end of the container 14 and is sealed to the container 14 by means of a hinge 23.. Alternatively the lid 22 is mounted to the container 14 by means of a bayonet coupling or a threaded connection.
  • a waterproof sealing is provided.
  • the waterproof sealing between the lid 22 and the container 14 may allow any air under pressure to escape from the interior of the cooling device 10.
  • an air-escape valve 32 is provided in the lid 22.
  • the keg 12 is initially, i.e. prior to use, filled with a beverage, preferably carbonised beer and contains a specific beverage volume such as 5 litres of beer.
  • a beverage preferably carbonised beer and contains a specific beverage volume such as 5 litres of beer.
  • the keg 12 is initially in a non-collapsed state.
  • the cooling device 10 is provided with a connector 24 mounted in the outer wall 20 of the container 14.
  • An external water hose 25 shown in Figs. 1 a and 1 b is connectable to the connector 24. Accordingly, through the connector 24 tap water may be introduced into the interior of the container 14.
  • the tap water which acts as a pressure medium - when the water is supplied to the container 14 and when the lid 22 is closed and sealed - sets the collapsible keg 12 under pressure and in turn sets the beer contained in the keg 12 under pressure.
  • the beer under pressure is then deliverable out of the keg 12 and may be discharged through means of an external tapping cock 26 as is per se well known in the art.
  • the tapping cock 26 is provided with a tapping handle 27.
  • the tapping cock 26 is connected to one end of a dispensing line 30.
  • the other end of the dispensing line 30 is connected to the keg 12.
  • Fig. 1b is a cross sectional view of the cooling device according to a first embodiment of the invention when supplied with ice.
  • a ice 28 or slush ice or a combination thereof is poured into the cooling device 10 through the upper open end of the container 14 as shown in Fig. 1 b.
  • any free space available within the cooling device i.e. the space between the keg 12 and the outer wall 20 and the space between the keg 12 and the upper open end of the container 14 is partly or preferably entirely filled with the ice 28, ice cubes and/or the slush ice.
  • the lid 22 is closed whereby the lid 22 seals off the container 14.
  • the applicant company has by experiments surprisingly discovered that the above mentioned 'free space available within the cooling device', i.e. a residual volume for receiving the ice 28 as the cooling medium being the difference between a specific inner volume of the container 14 when no keg 12 is present and the already mentioned specific beverage volume, constitutes less than 20% of the specific inner volume. With this relative low amount of the ice a sufficient and effective cooling of the beer inside the keg 12 is achieved.
  • the specific beverage volume i.e. the volume of the beer inside the keg 12 - when completely filled and delivered to the consumer - is 5 litres and the volume of the ice (to be poured in the residual volume) is 0,88 litres giving the ratio between the residual volume, i.e. the volume of ice, and the beverage volume of 5 litres equals 0,88 litres divided with 5 litres which is 17.6 %.
  • Fig. 1c is a cross sectional view of the cooling device according to a first embodiment of the invention in operation.
  • the lid 22 is closed and seals off the container 14, and tap water, e.g. from a water tap with a municipal water supply outlet, is supplied to the container 14 by means of the water hose 25.
  • the tap water is typically delivered with a pressure between 3 - 5 bar and causes the ice 28 as illustrated in Fig. 1c to float on top of the water filling out the above described residual volume by water and ice. Further, the ice slowly melts to water and the volumetric reduction through the melting of ice to water is replaced by tap water.
  • Fig. 2 is a cross sectional view of the cooling device according to a second embodiment of the invention.
  • the cooling device 10' according to the second embodiment of the invention also serves the purpose of discharging cold beer at a temperature of e.g. 5°-7° C from the collapsible beer keg 12' and utilises the same principle of working as discussed above in the three foregoing figures.
  • the water hose 25' is connectable to the cooling device 10' by means of a connector 24' mounted in the lid 22'.
  • the collapsible beer keg 12' and the beer therein is also under pressure from the mixture of water and ice 28' since the lid 22' is closed and sealed as the water hose 25' is connected to the cooling device 10' in order to supply water under pressure to the above described residual volume.
  • the container 14' has an outer wall 20' and the cooling device 10' utilises a principle known from a thermos, since the keg 12' is positioned initially within an inner thermally insulating container 21 having a double wall, i.e. a wall 21 a and a wall 21 b separated from one another by means of air. Alternatively, vacuum or an isolating material separates the walls 21 a and 21 b.
