Definitions

  • This invention relates to the dispensing of fluids and, in particular, relates to the dispensing of beer under pressure .
  • Beer drinkers are particularly fond of beer which is dispensed under pressure from a barrel.
  • the beer In commercial facilities, the beer is stored in large barrels and then dispensed under pressure from a beer tap. This is known as draught beer and is particularly popular the world over.
  • a problem with the domestic style of barrel is encountered in ensuring the beer is dispensed consistently at the required pressure .
  • boosters in the form of small, highly pressurised canisters that release a boost of gas, usually nitrogen or carbon dioxide, into the beer as the pressure within the barrel drops . It is these issues that have brought about the present invention.
  • a container for dispensing fluid under pressure having a top and a base having a raised floor supported by a downwardly depending skirt, a dispensing tap located in the container, the floor of the container having an aperture, a high pressure canister being profiled to fit within the skirt under the floor of the container, the canister having projecting therefrom a regulator which is adapted to fit into the aperture with the regulator extending into the container, the regulator having a primer whereby in use when the container is filled with fluid and the interior of the container pressurised the regulator is primed so that as the pressure in the container drops as the fluid is dispensed the regulator activates a valve in the canister to release gas under pressure into the container to elevate the pressure within the container to maintain a substantially constant pressure.
  • a container for dispensing fluid under pressure having a top and a base with a floor raised above the base by a downwardly depending skirt, a high pressure canister being positioned under the floor of the container within the skirt and having a regulator that is adapted to extend through the floor and into the container.
  • a method for preparing a container for dispensing of fluid under substantially constant pressure comprising attaching a pressure control device to the underside of the exterior of the container, the pressure control device having a regulator adapted to extend through the floor of the container into the interior of the container, the regulator including a primer whereby the method comprises securing the pressure control device to the container, filling the container with fluid, pressurising the container to a pressure slightly above the operating pressure via the dispensing tap, the pressure control device either being subsequently pressurised to an excess pressure or being supplied pre-pressurised to the excess pressure.

  • the toroidal canister has inwardly dished top and bottom walls 21 and 22 and has a central aperture 23 that supports a plug 30 that has a central throughway 31, an enlarged upper flange 32 that is welded to the upper surface of the top wall 21 of the canister 20 and a lower flange 33 which projects past the bottom wall 22 of the canister 20 to terminate approximately level with the base 12 of the barrel 10.
  • the throughway 31 is stepped to define a wide opening 36, a threaded portion 37 and an unthreaded passage 35.
  • the opening 36 is closed by a removable end cap 39.
  • a valve body 40 is screwed into the threaded passageway 37 and located in a sealed engagement with the plug 30 via an CD- ring 41.
  • the valve body 40 has a one-way valve including a valve member 42 located by a retainer 43 against a coil spring (not shown) .
  • the end 45 of the valve member 42 projects into a conical space 43 defined within the valve body 40 and the valve member 42 includes a head 47 which seats against an internal bore 48 of the valve member via an 0-ring 49.
  • the one-way valve is used to pressurise the canister 20 and the plug 30 has at least one aperture 46 that communicates with the interior of the canister.
  • the floor 13 of the beer barrel 10 has a centrally positioned aperture 16 and a circular mounting boss 17 with a central partially threaded aperture 18 is welded to the interior of the floor 13 of the barrel to extend across the aperture 16.
  • the upper flange 32 of the plug 30 has an upwardly and outwardly projecting spigot 38 which is externally threaded to screw into the boss 17 welded to the floor 13 of the barrel 10.
  • the spigot 38 in turn has an internally threaded aperture 39 that accommodates a screw threaded spigot 51 formed on the end of a second plug 60 that forms the base of the regulator 50 which extends into the barrel as shown in Figure 2.
  • the centrally located plug 30 welded to the canister 20 is screw threaded through the floor 13 of the beer barrel in the boss 17 with the regulator 50 extending into the interior of the beer barrel .

  • the space between the underside of the piston 73 and the one-way valve 62 is in communication with the interior of the barrel 10 and defines the first pressure chamber 71 and the space between the other side of the piston 73 and the cup seal 75 defines the second pressure chamber 72 or expandable chamber.
  • Projecting axially from the top of the second chamber 72 is the syringe body 81 which includes a piston 82 with a downward projection 83 constituting the primer 80.
  • the chamber seal 75 is annular with a peripheral lip 77 supported by an annular rib 78 with the peripheral lip 77 and annular rib 78 bearing against the wall of the chamber 76.

  • the piston 82 in the syringe body 81 is forced down to force gas past the chamber seal 75 into the second chamber 72.
  • the design of the chamber seal 75 is such that the pressure within the second chamber 72 on one side of the piston 73 is about 3 psi less than the pressure in the first chamber 71 on the other side of the piston 73 which equates to the internal pressure of the barrel 10.
  • the pressure in the first chamber 71 (about 17 psi) becomes greater than the internal pressure of the barrel 10 causing the piston 73 to be displaced downwardly to open the one-way valve 62 which causes release of the high pressure gas within the canister 20 to recharge the barrel 10.
  • the syringe piston 82 primes the cup seal 75 for use at start up to be operable once the barrel has been charged.
  • the one-way valve is activated causing the barrel to be recharged from the high pressure gas contained in the canister 20 in the base of the barrel.
  • the barrel, the pressurised canister and the plug which screws into the base of the barrel are all reusable.
  • the only disposable and redundant component is the regulator and primer.
