Description

    Field of the invention
  • The present invention relates to a connecting device for connecting an outlet of a beverage dispensing system via a dispensing line 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.
  • Background art
  • 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.
  • Furthermore, 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. Thus, the safety of the user of the dispensing device and the hygiene of the device have likewise become very important.
  • When dispensing beverage, such as beer, in a bar facility, it may sometimes be difficult for the personal to clean the device properly, or it might just be given a low priority in the daily routines.
  • Furthermore, often during replacement of the beverage container, the dispensing line is being reused without being cleaned. The consequence is that 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.
  • In addition, dispensing systems applying the use of disposable beverage containers are being used more and more frequently. In this regard, a need has arisen for being able to connect the dispensing line with the disposable container in an easy and expedient manner.
  • Summary of the invention

  • Detailed description of the invention
  • Figs. 1-8 show an embodiment of a connecting device 1 according to the present invention. Fig. 1 shows, in a cross-sectional view, the connecting device 1 having an axial extension 2 and comprising a first part 3 having a first end 4 and a second end 5 and a first fluid channel 6 extending between the first end 4 and the second end 5 of the first part 3. At the first end 4, the first part comprises piercing means 7 adapted to pierce a membrane (not shown) of the beverage container. Furthermore, the connecting device 1 comprises a second part 8 having a first end 9 and a second end 10 and a second fluid channel 11 extending between the first end 9 and the second end 10 of the second part 8. The second part 8 comprises a first projecting element 12 arranged at the first end 9 of the second part 8, the first projecting element 12 having a first radial length L1 extending in a radial direction in relation to the second part 8 and the second end 10 of the second part 8 is adapted to be connected with the dispensing line (not shown).
  • The second end 5 of the first part 3 is connected with the first end 9 of the second part 8 for to provide fluid communication between the first fluid channel 6 and the second fluid channel 11. Furthermore, the first part 3 and the second part are connected by the first projecting element 12 of the second part 8 engages into a corresponding recess 13 or groove arranged at the second end 5 of the first part 3. Thus when the second part is connected with the first part, the first projecting element 12 abuts the inner wall of the recess 13, whereby the first part 3 and the second part 8 are mechanically locked to each other. In this embodiment, the first end 9 of the second part 8 is inserted into the second end 5 of the first part 3.
  • Furthermore, a sealing element 14, here in the form of an 0-ring, is arranged above the first projection element 12 of the second element 8, so that the connection between the first fluid channel 6 and the second fluid channel 11 is sealed off.
  • In addition, the first part 3 comprises a second projecting element 15 having a second radial length L2 extending in a radial direction in relation to the first part 3. The second projecting element 15 is adapted to engage into corresponding engagement means (not shown) arranged on the beverage container or a part of the beverage container, and the second radial length L2 is larger than the first radial length L1. Hereby it is obtained that the connection to the beverage container of the first part 3 of the connecting device 1 is greater than the connection between the first part 3 and the second part 8 of the connecting device 1, whereby the second part 8 will be separated from the first part 3 before the first part will be separated from the beverage container. A further advantage is that it will be difficult to reuse the connecting device 1 after the first and second parts have been separated, whereby the connecting device 1 may assist in providing a one-way and disposable dispensing line solution for securing that a new dispensing line will be used each time a beverage container shall be replaced.
  • In Fig. 2, the second part 8 is shown in an outside view. At the first end 9, the first projecting element 12 is arranged. In this embodiment, the first projecting element 12 comprises a plurality of projecting arms projecting radially from the second part 8 and in an angle towards the first part. Due to the design of the projecting arms, they have a spring effect since during assembly of the first part 3 and the second part 8, the projecting arms pressed inwards against the wall of the second part, whereby they do not project radially until they are opposite the recess of the first part, whereby they project again and engage the recess. Furthermore, a special tool is necessary for assembling the first and second parts, whereby the projecting arms also serve to prevent the second part 8 from being inserted into the first part again after they have been separated, since the projecting arms have a larger diameter than the inner diameter of the second end of the first part. At a distance from the first projecting element 12, a circumferential groove 16 is arranged. The groove 16 is adapted to receive the sealing element. Furthermore, in this embodiment, the second part 8 also comprises two radially extending guide collars 17 arranged with a mutual distance for guiding the connecting device 1 in relation to the beverage container. A dispensing line is adapted to be connected at the second end 10.
  • Fig. 3 shows a cross-sectional view of the first part 3. The piercing means 7 is arranged at the first end 4 for piercing the membrane of the beverage container when the first part 3 is being brought into engagement with the beverage container. Preferably, the piercing means 7 have a cutting edge for facilitating the piercing. Above the first fluid channel 6, an insertion area 18 is arranged which is adapted to receive the first end of the second part. In the inner wall of this insertion area 18, the recess 13 is arranged. Furthermore, the second projecting element 15 is arranged on an L-shaped arm 19 extending radially from the first part, so that the projecting element 15 is facing the outer face of the first part and providing a distance between them, thereby defining a space 21. The second projecting element 15 has a triangular shape with a contact face 20 facing up against the L-shaped arm 19. The corresponding engagement means of the beverage container is adapted to be received in the space 21 so that the second projecting element 15 engages these as shown in Fig. 5.
  • Fig. 4 shows the first part 3 in a top view taken from the second end 5. In this embodiment, the first part 3 comprises four L-shaped arms 19 each comprising a second projecting element.
  • Fig. 5 shows, in a cross-sectional view, the connecting device 1 in relation to a cap 22 of a beverage container (not shown). The second part 8 is connected with the dispensing line 23. The guide collars of the second part 8 are positioned in a guide 24 for aligning the connecting device 1 with the beverage container. The first element 3 has been forced downwards against and through a membrane of the cap 22 so that the membrane has been pierced and the inside of the beverage container is in fluid communication with the dispensing line 23.
  • Fig. 6 shows an enlarged view of the area B of Fig. 5. In this view it is easily deducible how the engagement means 25 of the cap 22 have entered into the space so that the second projecting elements 15 engage and mechanically lock each other.
  • Figs. 7 and 8 show the guide 24 assisting in guiding and positioning the connecting device 1 in relation to the cap 22 and thereby beverage container. Figs. 9-11 show another embodiment of a connecting device 1 according to the present invention. This embodiment has substantially the same design and function as the one shown in Figs. 1-8. However, the second part 8 of the connecting device 1 comprises only one guide collar 17 adapted to engage with the guide 24 for positioning the connecting device in relation to the cap 22 as shown in Figs. 10 and 11.
  • Figs. 12-16 show yet another embodiment of a connecting device according to the present invention. Again the connecting device of the present embodiment has substantially the same design and function as the one shown in Figs. 1-8.
  • In Fig. 12, the connecting device 1 is shown in a cross-sectional view. The first part 3 comprises a recess 26 arranged on the outside at the second end 5. The second projecting element 15 is, in this embodiment, arranged in the recess 26, and comprises a ring-shaped element having three radially extending arms arranged around the ring-shaped element with a mutual distance, as shown in Fig. 16.
  • Fig. 13 shows the connecting device 1 inserted in the cap 22 in a top view. Fig. 14 shows, in a cross-sectional view, the connecting device 1 in relation to a cap 22 of a beverage container (not shown). The second part 8 is connected with the dispensing line 23. The guide collar 17 of the second part 8 is positioned in a guide (not shown) for aligning the connecting device 1 with the beverage container. The first element 3 has been forced downwards against and through a membrane of the cap 22, so that the membrane has been pierced and the inside of the beverage container is in fluid communication with the dispensing line 23.
  • Fig. 15 shows an enlarged view of the area B of Fig. 14. In this view it is easily deducible how the second projecting element 15, here in the form of the three radially extending arms, engages the cap 22 and thereby mechanically locks the first part 3 to the cap 22. The ring-shaped element may be made of metal, whereby the second projecting element is 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, which may be made of a plastic material.
  • Figs. 17-20 show an additional embodiment of a connecting device 1 according to the present invention. This embodiment has substantially the same design and function as the one shown in Figs. 12-16.
  • In Fig. 17, the connecting device 1 is shown in a cross-sectional view. The first part 3 comprises a recess 26 arranged on the outside at the second end 5. In this embodiment, the second projecting element 15 is arranged in the recess 26 and comprises a capsule-shaped element extending radially out from the recess 26 and has a substantially vertical extension. On the inside of the vertical extension, engagement means are arranged adapted for engaging corresponding engagement means arranged on the cap as shown in Figs 18 and 19. The capsule-shaped element 15 is shown in Fig. 20 in an outside view.
  • Fig. 18 shows in a cross-sectional view the connecting device 1 in relation to a cap 22 of a beverage container (not shown). The second part 8 is connected with the dispensing line 23. The guide collar 17 of the second part 8 is positioned in a guide (not shown) for aligning the connecting device 1 with the beverage container. The first element 3 has been forced downwards against and through a membrane of the cap 22, so that the membrane has been pierced and the inside of the beverage container is in fluid communication with the dispensing line 23.
  • Fig. 19 shows an enlarged view of the area B of Fig. 18. In this view it is easily deducible how the second projecting element 15, here in the form of the capsule-shaped element, engages the cap 22 and thereby mechanically locks the first part 3 to the cap 22.
  • Figs. 21-23 show a further embodiment of a connecting device 1 according to the present invention. This embodiment has substantially the same design and function as the one shown in Figs. 12-16.
  • In Fig. 21, the connecting device 1 is shown in a cross-sectional view. The first part 3 comprises the second projecting element 15 which, in this embodiment, is extending radially from the first part 3 and in an angle towards the second part 8. Thus, when the connecting device 1 is connected with the cap 22, the second projecting element 15 extends radially out from the first part 3 and towards the second part and thereby the cap 22, as shown in Figs. 22 and 23.
  • Fig. 22 shows, in a cross-sectional view, the connecting device 1 in relation to a cap 22 of a beverage container (not shown). The second part 8 is connected with the dispensing line 23. The guide collar 17 of the second part 8 is positioned in a guide (not shown) for aligning the connecting device 1 with the beverage container. The first element 3 has been forced downwards against and through a membrane of the cap 22, so that the membrane has been pierced and the inside of the beverage container is in fluid communication with the dispensing line 23.
  • Fig. 23 shows an enlarged view of the area B of Fig. 22. In this view it is easily deducible how the second projecting element 15 will engage the cap 22 if pulled out of the cap 22, since the second projecting element 15 will engage the cap 22 and thereby mechanically lock the first part 3 to the cap 22.
  • Fig. 24 shows another embodiment of the connecting device 1. Fig. 24 shows, in a cross-sectional view, the connecting device 1 comprising a first part 3 having a first end 4 and a second end 5, and a first fluid channel 6 extending between the first end 4 and second end 5 of the first part 3. At the first end 4, the first part comprises piercing means 7 adapted to pierce a membrane (not shown) of the beverage container. Furthermore, the connecting device 1 comprises a second part 8 having a first end 9 and a second end 10 and a second fluid channel 11 extending between the first end 9 and second end 10 of the second part 8. The second part 8 comprises a first projecting element 12 arranged at the first end 9 of the second part 8, the first projecting element 12 having a first radial length L1 extending in a radial direction in relation to the second part 8 and the second end 10 of the second part 8 being adapted to be connected with the dispensing line (not shown).
  • The second end 5 of the first part 3 is connected with the first end 9 of the second part 8 to provide fluid communication between the first fluid channel 6 and the second fluid channel 11. Furthermore, the first part 3 and second part are connected by the first projecting element 12 of the second part 8 engaging into a corresponding recess 13 or groove arranged at the second end 5 of the first part 3. Thus, when the second part is connected with the first part, the first projecting element 12 abuts the inner wall of the recess 13, whereby the first part 3 and the second part 8 are mechanically locked to each other. In this embodiment, the first end 9 of the second part 8 is inserted into the second end 5 of the first part 3.
  • In addition, the first part 3 comprises a second projecting element 15 having a second radial length L2 extending in a radial direction in relation to the first part 3. The second projecting element 15 is adapted to engage into corresponding engagement means (not shown) arranged on the beverage container or a part of the beverage container, and the second radial length L2 is larger than the first radial length L1. Hereby it is obtained that the connection to the beverage container of the first part 3 of the connecting device 1 is greater than the connection between the first part 3 and the second part 8 of the connecting device 1, whereby the second part 8 will be separated from the first part 3 before the first part will be separated from the beverage container. A further advantage is that it will be difficult to reuse the connecting device 1 after the first and second parts have been separated, whereby the connecting device 1 may assist in providing a one-way and disposable dispensing line solution for securing that a new dispensing line will be used each time a beverage container shall be replaced.
  • Fig. 25 shows, in a cross-sectional view, a top part of the beverage container 27 with a cap 22 having a membrane 28. The beverage container 27 is arranged below an upper pressing part 29, wherein the connecting device 1 has been arranged and is being positioned in relation to the beverage container by the guide 24. In Fig. 26, the beverage container 27 has been moved towards the upper pressing part 29, so that the membrane of the cap has been moved up against the first part 3 of the connecting device 1 which has then been forced through the membrane and pierced it, so that the inside of the beverage container is in fluid communication with the dispensing line 23.
  • Fig. 27 shows an enlarged view of the area F of Fig. 26. In this view it is easily deducible how the second projecting element 15 of the first part 3 has been moved past the engagement means 25 of the cap 22, so that the second projecting element 15 engages and mechanically locks each other.
  • Furthermore, a ball valve 30 may be arranged inside the second part 8.
  • In Fig. 28, the beverage container 27 has been moved away from the upper pressing part 29, whereby the second part 8 has been separated from the first part 3 according to the inventive idea.
  • In Fig. 29, a beverage dispensing system 100 according to the invention is shown in a cross-sectional view. The system 100 comprises a beverage container 27 having a beverage and propelling means 31 for forcing the beverage out of the container into a dispensing line 23.
