Definitions

  • This invention relates to a tamperproof cap for a keg spear, as provided on beer kegs.
  • a keg spear is screw-engaged in a keg and has an external access portion comprising a peripheral wall defining a recess, an access device being provided in the recess.
  • the peripheral wall is provided with an outwardly extending annular projection and a tamper-evident cap has a ring of teeth, which can be snap-engaged over the annular projection to cover the recess and prevent the keg contents being accessed without removal of the cap.
  • the keg spears are generally made with the peripheral walls of the same diameter, within tolerances.
  • the annular projections are made of different profiles by different manufacturers and the different profiles have, for example, varying axial depths. This makes it difficult to produce a cap, which is satisfactory with all keg spears.
  • the cap has to be sufficiently resilient to snap over the annular projections of different profiles, but must be brittle enough for the cap to break, if an attempt is made to remove the cap. This has proven to be difficult to achieve in practice.
  • brittle materials means that different caps have to be made for different profiles and/or there are numerous failures when the caps are applied, whereas use of less brittle materials enables the cap to be removable without damage. This is sometimes achieved by gently warming the cap, if it is thermoplastic, so that it becomes easier to remove.
  • One tamper-evident cap relies on brittleness of the material, so that the teeth, snap-engaged over the annular projection, break when an attempt is made to remove the cap. This is unsatisfactory for several reasons.
  • the cap is not usable with all keg spears, because of poor tolerances.
  • the brittleness of the material means that tolerances have to be small.
  • the cap is preferably made of high density polyethylene, or polypropylene, which provides sufficient resilience for fitting different keg spear profiles, but which make it very difficult to re-adhere the tamper-evident ring in its correct position, without causing obvious damage as evidence of tampering.
  • the cap With a keg spear, the cap is non-removably fixed on the keg spear, removal only being possible by destruction of the cap.
  • the cap is rotatable on the keg-spear. The problem to be met is not to provide tamper evidence of rotation, but to provide tamper evidence of levering off of the cap.
