Definitions

  • This invention relates to kegs or like containers for pressure dispensed liquids such as beer.
  • Beer kegs are subject to rough handling in use and may have to contain pressures of up to 413 kNm -2 (60 psig) exerted by the gas that displaces the beer to empty the keg.
  • pressures up to 413 kNm -2 (60 psig) exerted by the gas that displaces the beer to empty the keg.
  • Conventional kegs are therefore of expensive, rugged construction and are only economic if they are refilled and reused many times. Hence they are designed to be free draining, readily washable/sterilisable and may incorporate features aiding repair, such as replaceable end chimes, further adding to manufacturing costs.
  • the costs of keg cleaning and repair and the capital cost tied up in the kegs themselves can account for a significant proportion of beer delivery costs.
  • GB 510 069 proposes a double walled cask of stainless steel/galvanised iron construction. Again this design is not intended for use in pressure dispense systems; besides which it is complex and expensive to manufacture.
  • the present invention provides a single or limited usage container for pressure dispensed liquids such as beer, comprising a hollow mild steel body provided internally with a protective polymeric lacquer and which is capable of containing service pressures of 400 kNm -2 .
  • the expression "limited usage container” as used herein means a container intended to be used only once, or to be used and refilled only a few times, in contrast to a conventional keg which is refilled many times.
  • the lacquer is a phenolic resin lacquer of per se known kind, as used to line the interior of aluminium kegs, baked onto the inside of the container.
  • the container body may comprise two halves, each formed as a deep drawn pressing, united by a circumferential weld.
  • the container may be provided with an end chime formed from steel wire or rod, welded to the container top.
  • a similar end chime may be provided at the container bottom, allowing both ends of the container to be convex and therefore inherently resistant to internal pressure, as well as containing no "dead spaces" and therefore being free draining, readily washed and sterilised.
  • the container bottom may be generally concave, sufficiently dished and having a peripheral stiffening channel to resist internal pressure, the channel also providing a stable base upon which the container can stand.
  • a transverse, preferably diametral, channel in the container bottom may communicate with the peripheral channel and form a well or sump into which an extractor spear extends in use, allowing the container to be drained substantially completely.
  • the extractor spear may have an offset bottom end, communicating with the peripheral channel.
  • the bottom or, where present, the bottom end chime, of the container is preferably configured to interengage with the top end chime of an identical container, allowing two or more such containers to be stably stacked.
  • the illustrated kegs 10, 20 comprise two deep drawn mild steel pressings 12, 14 of approximately 1.0 mm thickness, sufficient to resist internal pressures as stipulated for example in the relevant United Kingdom Allied Brewery Traders Association test specification.
  • the pressings 12, 14 form the two ends of the keg and are united by a circumferential weld 16.
  • Mild steel is cheaper than stainless steel or aluminium of equivalent strength, and as the keg is only intended to have limited usage, its construction need not be as rugged as is conventional, leading to further materials savings.
  • low cost end chimes 18, 22 formed from thick steel wire or rod are welded to the pressings 12, 14 respectively.
  • a keg neck 24 is welded in an aperture in the pressing 12.
  • the end chime 22 is omitted and the pressing 14 is provided with a concave end 26, a peripheral stiffening channel 28 that also serves as a stable base for the keg, and a diametral sump forming channel 30 aligned with the neck 24 axis and communicating with the channel 28.
  • This embodiment may be more difficult to wash than the figure 3 embodiment, and is primarily intended for single use only, i.e. not for refilling.
  • the diametral channel may be omitted to provide a plain concave keg bottom as indicated by dotted line 32.
  • An extractor spear having an offset end communicating with the peripheral channel 28 is then used to fully drain the keg contents.
  • the wire or rod top end chime 20 of figure 3 is replaced by an end chime 33 fabricated in mild steel sheet, welded at 34 to the top of the keg body 12.
  • the end chime 33 has a rolled lip 36, and circumferentially spaced drainage holes 38.
  • a similar end chime (not shown) may replace the wire or rod bottom end chime 22 of figure 1.
  • the keg interior is cleaned/degreased e.g. using a phosphate based cleaner, and then covered in phenolic resin lacquer (not shown) such as EPIKOTE MD2019, available from Holdens Surface Coatings Ltd., Birmingham, England, baked on at a temperature of 210°C for 20 minutes.
  • phenolic resin lacquer such as EPIKOTE MD2019, available from Holdens Surface Coatings Ltd., Birmingham, England
