Definitions

  • This invention covers a method for lubrication and sealing of cork stoppers and for the organoleptic preservation of the contents of these containers.
  • cork stoppers were coated with hydrocarbon based lubricating agents such as paraffin and vaselin to facilitate stoppering and later removal of the corks and to guarantee perfect sealing and organoleptic preservation of the product.
  • this invention has the aim further to improve on known techniques by a new method based upon a peculiar association of products and their preparation.
  • paraffins were used for cork stopper lubrication, but these paraffins cannot be used for pasteurization purposes because of their low melting point.
  • paraffins have proved to be excellent and harmless lubricants and sealants for cork stoppers, so that this invention has the aim to ensure their re-utilization by batching them with suitable other products in order to create a thermostable product having good lubrication and sealing characteristics.
  • Stabilization of the two main constituents in the batch i.e. silicone fluid and paraffin, which are chemically incompatible since they are mutually insoluble, non emulsifiable in absence of solvents and are having completely different melting points, is achieved by adding pyrolitic silica gel acting as a thickener of the silicone fluid and a mix of finely homogenized, thermal and physically stable constituents.
  • the paraffin is oxystabilized, for instance, by adding butyloxyanisole or a synergic mixture of butyloxyanisole and dodecylgallate.
  • Metal stearates like lithium, magnesium, sodium, calcium etc. will also be added as anti stick-slip agents to ensure dynamic and static balancing of the friction coefficient of the cork stopper at a rational average value.
  • the dynamic component has indeed the aim to provide for smooth stoppering and unstoppering of the bottles, whereas the static component shall provide for a perfect seal and prevent the liquid from seeping along the cork surface into the bottle when no proper steps are taken to keep the bottles in upright position for at least 24 hours after stoppering to allow for re-expansion of the cork stoppers.
  • pigments such as titanium bioxide and iron oxides may be added, to dye the processed corks in various shades, according to specific requirements.
  • plastic polymers like tetrafluorethylene (TFE) suitable for foodstuffs may also be added.
  • TFE tetrafluorethylene
  • Preparation of the compound subject matter of this invention can be by hot or cold processing.
  • the hot process is sequenced as follows:
  • paraffin may be substituted by F.U. viscous Vaseline or soft white vaseline which requires no powdering.
