Definitions

  • the present invention relates to a connecting device for connecting an outlet of a beverage dispensing system via a dispensing line having a first inner diameter to a beverage container.
  • the present invention also relates to a dispensing line and a beverage dispensing system as well as to a method for connecting an outlet of a dispensing line with a beverage container and a method for disconnecting an outlet of a dispensing from a beverage container.
  • Dispensing of beverage such as beer, has become more in focus with the consumer due to the fact that beer consumers have become increasingly aware of the quality of the beer and tend to base their beer label preferences on the final impression of the beer, i.e. the dispensed beer.
  • the impression of a newly dispensed beer is influenced by the taste and how it appears to the consumer. Also, the taste of the beer may change as the temperature of the beer varies. In view of this, it is of high importance that the dispensing devices serve the purpose of dispensing beer within the right temperature range and with the right amount of CO2 in the beer.
  • the amount of CO2 in a newly dispensed beer is influenced by the amount of CO2 applied to the beer at the time of manufacture and also by the conditions under which the beer has been stored.
  • the amount of CO2 applied to the beer will migrate out of the beer if the beer is not kept under pressure in the beer keg. Therefore, it is very important that the pressure of the CO2, besides being adequate for dispensing the beer, is also adequate for keeping the pressure balance in the beer keg, hence keeping the beer fizzy and foamy after dispensing.
  • beer dispensing devices have become within the reach of more consumers and are increasingly being installed in private homes, companies, sports facilities etc., where no trained personal is operating the dispensing devices.
  • the safety of the user of the dispensing device and the hygiene of the device have likewise become very important.
  • the dispensing line is being reused without being cleaned.
  • the dispensing line may contain old beverage and that for instance bacteria are present. This may result in a bad taste of the beverage, or even, in some instances, constitute a health risk for the consumer.
  • dispensing systems applying the use of disposable beverage containers are being used more and more frequently.
  • a need has arisen for being able to connect the dispensing line with the disposable container in an easy and expedient manner.
  • a further object of the present invention is to provide a connecting device which ensures that a dispensing line may be used only once for one beverage container.

  • first projecting element may comprise one or more projecting arms.
  • the second projecting element may be made of a different material than that of the first projecting element, the different material being less flexible than that of the first projecting element.
  • first projecting element along the radial direction may have a first thickness and the second projecting element along the radial direction may have a second thickness, the second thickness being larger than the first thickness.
  • the piercing means may have a cutting edge.
  • the sealing element may be arranged above the first projection element of the second element.
  • the second projecting element may be arranged on a projecting arm which projects radially from the first part.
  • the second projecting element may be extending radially from the first part and in an angle towards the second part.
  • the first projecting element may project radially from the second part and in an angle towards the first part.
  • the second projecting element may be adapted to engage into corresponding engagement means arranged on the beverage container or a part of the beverage container.
  • first and/or the second projecting elements may be extending around the first part or the second part, respectively.
  • the second part may comprise a centre tube part, the centre tube part having a second inner diameter, the second inner diameter being larger than the first inner diameter of the dispensing line.
  • the centre tube part may have a first wall thickness and the centre tube part may comprise a measuring area having a second wall thickness, the second wall thickness being smaller than the first wall thickness, whereby a pressure of the beverage in the centre part is measured via the measuring area.
  • the present invention also relates to a dispensing line comprising a tube section having an inlet end and an outlet end, the inlet end being connected with the connecting device as described above.
  • Said outlet end in the dispensing line as described above may be connected with a spout and/or a valve.
  • the present invention relates to a beverage dispensing system comprising a beverage container having a beverage and propelling means for forcing the beverage out of the container into a dispensing line, wherein the dispensing line and the beverage container are connected via the connecting device as described above.
  • the propelling means may be mechanical pressure means.
  • the beverage container may comprise a cap arranged in connection with an opening in the beverage container, the cap comprising a membrane to be pierced by the piercing means, and engagement means adapted to engage the second projecting element of the first part of the connecting device.
  • the present invention also relates to a method for connecting an outlet of a beverage dispensing system via a dispensing line with a beverage container, comprising the steps of:
  • the present invention relates to a method for disconnecting an outlet of a dispensing line from a beverage container, comprising the steps of:
  • the method for disconnecting an outlet of a dispensing line from a beverage container as described above may also comprise the step of providing access to the second part of the connecting device, before pulling the second part and/or the beverage container.
  • the propelling means may be an upper pressing part and a lower pressing part, the second part of the connecting device being mounted in the upper pressing part, the method comprising the further step of releasing the beverage container from the upper pressing part by means of a dismantling tool when the lower pressing part is moved away from the upper pressing part and at the same time separating the second part from the first part of the connecting device.
