Definitions

  • the present invention relates to a dispense head adapted to be coupled to a beverage container above a spear arranged in the beverage container in a dispensing system, the dispense head comprising a piston arranged axially displaceable within a housing, the piston being connected to a handle so that upon activation of the handle, the piston will be displaced axially towards the spear, whereby a top part of the spear will be forced downwards, causing it to open the beverage container, a gas inlet arranged in the housing, which is in fluid communication with a space extending along the piston, the space being sealed at least at a top end with a first sealing and at a bottom end with a second sealing.
  • the present invention also relates to a dispensing system.
  • the beverage is stored in a container, such as a keg, which is connected to a dispensing system during use.
  • the beverage flows from the container through a dispensing line which is typically connected to a dispensing tap where the beverage is dispensed.
  • the flow of beverage may for instance be achieved by a higher than atmospheric pressure inside the container, forcing the beverage into the dispensing line.
  • pressure is usually continuously applied to the inside of the container by means of a pressure medium. It is common to use CO2 as the pressure medium.
  • the pressure medium is usually supplied to the beverage container from a gas cylinder via a dispense head. Also, it is common that the dispense head connects to the beverage outlet of the container, whereby it serves to supply pressure medium, such as CO2, to the beverage container and beverage to the dispensing system.
  • pressure medium such as CO2
  • the pressure medium flow is connected to the dispense head first, and subsequently the beverage flow is connected.
  • One drawback of this is that it entails a risk of foaming once the beverage flow is connected, which is at best messy and at worst dangerous for the user if the pressure is high enough to cause equipment failure.
  • a dispense head which is inexpensive to manufacture and simple yet provides a satisfactory prevention of pressure medium leakage and foaming.
  • CO2 is a hazardous gas if the total content of gas in a room becomes too high. Normal concentration of CO2 in the atmosphere is 0.03 Vol.-%. If the amount of CO2 reaches a level of 2 to 3 Vol.-%, the people in the room will experience higher respiration and higher pulse frequency. This will increase with the increasing level of CO2 and end up in unconsciousness. If the level exceeds 10 Vol.-%, it is deadly, even if the people in the room are exposed for only a short period of time.
  • CO2 is an expensive gas, and thus, leakage of the gas may also be a costly affair.
  • a dispense head according to the preamble of claim 1 is known from US-A-4 450 853 .
  • the dispense head comprising a piston arranged axially displaceable within a housing, the piston being connected to a handle so that upon activation of the handle, the piston will be displaced axially towards the spear, whereby a top part of the spear will be forced downwards, causing it to open the beverage container, a gas inlet arranged in the housing, which is in fluid communication with a space, which space is extending along the piston, the space being sealed at least at a top end with a first sealing and at a bottom end with a second sealing, wherein positioning means is arranged in connection with the piston, enabling the first sealing and the second sealing to be placed in sealing positions during unintended activation of the handle when the dispense head is disconnected from the beverage container.
  • the piston When the handle is activated, the piston is displaced downwards inside the housing. During this displacement, the sealings follow the piston by means of the positioning means so that the space being in fluid connection with the gas inlet is sealed off, whereby gas, i.e. CO2, is unable to escape and leak unintendedly.
  • gas i.e. CO2
  • the positioning means secures that the dispense head is not able to leak CO2 even when it is activated and in a dismounted state.
  • the piston When the dispense head is coupled to the beverage container above the spear and the handle is activated, the piston is displaced downwards inside the housing. During this displacement, the sealings follow the piston by means of the positioning means so that the space being in fluid connection with the gas inlet is sealed off until the piston displaces the top of the spear and thereby opens the beverage container.
  • the internal spring of the spear has more power, i.e. spring force, than the inherent force of the positioning means, meaning that when the dispense head is in the mounted and activated state, the piston will be pressed slightly upwards by the internal spring, or the internal spring of the spear stops the piston in displacing it further downwards during activation so that the gas inlet is in fluid communication with the beverage container.
  • the positioning means may be a resilient element, such as a spring, or may be made of an elastic material.
  • the positioning means may have a predetermined spring force.
  • the positioning means may be arranged above the first sealing.
  • the space may be an annulus extending along the piston.
  • the space may be arranged between an exterior of the piston and the housing, or is arranged within the piston.
  • sealings may be arranged so that they seal radially against a projection either on the housing or within the piston.
  • sealings may be O-rings or other sealing elements.
  • the piston may have an axial bore adapted for a beverage to be led through the dispense head during dispensing.
  • the present invention also relates to a dispense head adapted to be coupled to a beverage container above a spear arranged in the beverage container in a dispensing system, the dispense head comprising:
  • a helically spring may be arranged above the sleeve and adapted to force the sleeve downwards against a main gasket, which may be adapted to force the sleeve upwards when the dispense head is mounted and activated on the beverage container.
  • a sealing e.g. an o-ring, may be arranged between the sleeve and the piston for avoiding unintended gas leak.
  • an additional sealing may be arranged below the opening of the bore for sealing between the sleeve and the bore, when the sleeve is in its lowest position.
  • the present invention further relates to a dispense head adapted to be coupled to a beverage container above a spear arranged in the beverage container in a dispensing system, the dispense head comprising:
  • a helically spring may be arranged above the sleeve for forcing the sleeve downwards.
  • the channel may be arranged within the wall of the sleeve or it may be an axial groove arranged at the inside of the sleeve.
  • the sleeve may comprise a radial flange, which is adapted to abut a main gasket, which may force the sleeve upwards when the dispense head is mounted and activated on the beverage container.
  • a sealing e.g. an O-ring, may be arranged below the opening for sealing between the sleeve and the opening, when the sleeve is in its lowest position.
  • the housing may comprise an upper sealing and a lower sealing arranged with a mutual distance between them.
  • the sealings may be arranged in their own recesses in an interior wall of the housing and may preferably be O-rings.
  • the sealings may be arranged so that they are positioned on each side of the gas inlet.
  • the sleeve may be made of metal or plastic material, or a combination thereof.
  • the present invention also relates to a dispensing system for dispensing beverage, the system comprising a beverage container, which comprises a spear arranged in an opening of the beverage container adapted to function as a valve, the spear having an internal spring having a spring force so that the opening to the beverage container can be kept closed, a gas supply, a dispensing tap, and a dispense head according to any of the above-mentioned technical features.
  • the spring force of the spring element may be smaller than the spring force of the internal spring.

  • the dispensing system 1 comprises a beverage container 2, such as a keg.
  • the beverage container 2 comprises a spear 3 arranged in an opening (not shown) of the beverage container 2 adapted to function as a valve, the spear 3 having an internal spring (not shown) having a spring force enabling the opening to the beverage container 2 to be kept closed.
  • the dispensing system 1 also comprises a gas supply 4.
  • the gas supply 4 may be a CO2 container and may be connected to a dispense head 5 according to the invention.
  • the dispense head 5 will be described in more detail below.
  • a dispensing tap 6 is connected to the dispense head 5 via a dispensing line 7.
  • a cooling device 8 is arranged between the dispensing tap 6 and the dispense head 5 to cool the beverage before dispensing.
  • the gas supply 4 supplies pressurised gas, such as CO2 or other suitable gasses, via the dispense head 5 to the top of the beverage container 2 in order to displace the beverage.

  • the dispense head 5 also comprises a piston 14 which is arranged axially displaceable within the housing 13.
  • the piston 14 is connected to the handle 9 so that, upon activation of the handle 9, the piston 14 will be displaced axially towards the spear (not shown), whereby a top part of the spear (not shown) will be forced downwards, causing it to open the beverage container (not shown). From Fig. 3 , it is easily deduced that the lower part 15 of the piston 14 is displaced downwards in relation to the housing 13.
  • the gas inlet 10 is arranged in the housing 13 and is in fluid communication with a space 16.
  • the space 16 extends along the piston 14 and is in this embodiment positioned within the piston 14.
  • the gas inlet 10 is in fluid communication with the space 16 via one or more openings 17 in the piston wall.
  • the space 16 is sealed at least at a top end with a first sealing 18 and at a bottom end with a second sealing 19.
  • a positioning means 20 is arranged in connection with the piston 14, enabling the first sealing 18 and second sealing 19 to be placed in sealing positions when the handle 9 is activated unintendedly during axial displacement of the piston when the dispense head 5 is dismounted from the beverage container 2.
  • Fig. 4 is an enlarged cross-sectional view of the dispense head of Fig. 3 , wherein the second sealing 19 is in a sealing position even though the dispense head 5 has been activated unintendedly.
  • the sealings 18, 19 are O-rings made of an elastic material. These O-rings extend around an inner piston part 21 and are securely placed in recesses of the inner piston part 21 so that they not are displaceable in an axial direction of the inner piston part 21.
  • projections 22 are arranged on the inner side of piston wall 23 so that the sealings 18, 19 are slightly deformed when being placed opposite the projections 22. In this way, the space 16 is sealed off radially, meaning that no CO2 will leak into the surroundings even though the dispense head 5 has been activated unintendedly.
