Definitions

  • This invention provides improved closures for use in connection with food or beverages.
  • One application is in relation to closures for wine bottles.
  • corks made from natural cork material.
  • this material can be subject to initial flaws, or deteriorate in use, resulting in contamination or spoilage of the wine.
  • oxidation of the wine due to permeation of oxygen through the cork into the wine, results in vinegar flavour.
  • vinegar flavour due to the presence of trichloro-anisoles (TCA) and other undesirable flavour-active or odour-active compounds in the cork, imparts a musty or mouldy smell and flavour to the wine.
  • TCA trichloro-anisoles
  • Leakage can also be a problem.
  • cork is a relatively expensive material, as most supplies still come from Portugal.
  • Synthetic "corks” and screw-cap stoppers have been used in the wine industry, but have not yet been tested adequately over the prolonged storage periods of quality red wines. There is some indication, however, that synthetic "corks” may impart flat flavours to wines. Furthermore, there is considerable consumer resistance to use of synthetic "corks” and screw-cap stoppers, particularly for quality wines. A further disadvantage is that synthetic "corks” are generally far more difficult to remove, using a hand-operated corkscrew, than natural corks.
  • the first cork coatings were simply lubricants such as paraffin and Vaseline. These merelv ensured that the cork was easier to insert into the bottle and later remove, without disintegration. The other problems associated with cork stoppers were not addressed.
  • materials used in surface treatment of corks include oils and silicone resins, emulsions of various formulations, as well as some synthetic coatings. These coatings do prevent leakage of the wine, but do not provide a barrier against taint and oxidation.
  • Hybrid corks have been moulded from natural cork and synthetic cork cells made from a synthetic polymer.
  • the synthetic cells fill the gaps between the cork cells, and a binding agent (such as polyurethane) is used to bind the cells together.
  • a binding agent such as polyurethane
  • hybrid corks have to date proved unsatisfactory, as they often leak and can disintegrate and be difficult to extract from a bottle.
  • the present invention provides an improved closure having a surface coating or diffusion layer comprising an appropriate polymer.
  • This coating or diffusion layer has many properties which are of benefit when used (for example) in relation to corks (either natural or synthetic) for wine bottles.
  • the coating or diffusion layer limits oxygen permeability, inhibits or prevents the diffusion of rrichloro-anisoles (TCA) and other flavour-active or odour-active compounds from the cork to the alcoholic beverage, adheres strongly to the cork and/ or penetrates into the surface of the cork, is sufficiently flexible to be capable of withstanding compression and decompression during the corking process, enables the coated cork to be readily extracted from the bottle, reduces or prevents wine leakage, is resistant to sulphur dioxide, and has long life under alcoholic beverage conditions.
  • TCA rrichloro-anisoles
  • These coatings or diffusion layers are also applicable to substrates other than cork (eg packaging and wrapping materials) which are in contact with food products or beverages.
  • an appropriate polymer which forms a physical barrier to gases (eg oxygen) and flavour-active or odour-active compounds (eg TCA), is applied as a surface coating or diffusion layer to a substrate for use in contact with food products or beverages.

  • flavour-active or odour-active compounds eg TCA
  • Polymeric materials the molecular structure and/ or morphology of which help to prevent permeation of gases and vapours (such as oxygen) and flavour-active or odour-active compounds (commonly know as taint compounds), can be classed as barrier polymers.
  • Barrier polymers with low oxygen permeability see RTajima, A.Banba, M. Takanori, T.
  • the present invention provides a method for producing a coating or diffusion layer on a substrate (eg a cork) for use in contact with a food product or beverage, said coating or diffusion layer preventing or inhibiting passage therethrough (eg from a cork to an alcoholic beverage) of flavour-active or odour-active compounds, and said method comprising applying to the surface of said substrate an effective amount of a barrier polymer, said barrier polymer being a polymeric material, the molecular structure and/ or morphology of which prevents or inhibits passage therethrough (eg from a cork to an alcoholic beverage) of flavour-active or odour-active compounds.
  • the present invention provides a coated substrate, and in particular a coated natural or synthetic cork, produced according to that method.

  • the polymer is selected so as to form a physical barrier to the passage of gases and flavour-active or odour-active compounds.
  • the polymer coating or diffusion layer of the present invention will prevent any flavour- active or odour-active compounds migrating from a cork to an alcoholic beverage. It must also adhere strongly to the substrate and/ or penetrate into the surface of the substrate, and be sufficiently flexible for its proposed use (eg to withstand compression and decompression during the corking process, if the substrate is a cork).
  • the polymer coating or diffusion layer must enable the coated cork to be readily extracted from the bottle, prevent wine leakage, and have long life under alcoholic beverage conditions.

  • the corks were immediately dipped into the solution and allowed to cure in an oven at 80 C for 30 minutes.
  • a bistriethoxysilane (BTSE) solution was prepared by adding ethanol to a 5% BTSE-in-water solution adjusted to a pH of 10 with acetic acid. The solution was allowed to hydrolyse for 48 hours.
  • a TCA spiked cork was dipped into this solution and quickly dried with compressed air. Next, the cork was dipped into a 2% amino propyltriethoxysilane-in- water solution, which had been allowed to hydrolyse for 48 hours. The cork was then cured in an 80°C oven for 10 minutes.
  • the coating formulation consisted of a mixture of 75mL of polyvinyiacetate emulsion (PVA) and 25mL of polymethylhydrogen siloxane emulsion. 100 corks were placed into a tumbler and 20mL of the coating formulation was distributed casually over the corks.

  • Corks were dipped into this coating and allowed to cure in an oven at 40 C for 24 hours.
  • the polymer was diluted to 25% (v/v) with ethanol and the cork was dipped into this coating and then dried at 40 C for 24 hours.
  • Polyethylene vinyl alcohol (EVOH) film (9g) was placed into a reaction vessel and purged with nitrogen for several minutes. Toluene (280mL), isocyanatopropyltriethoxysilane (lOmL) and dibutyltin dilaurate (lmL) were added and the reaction was allowed to proceed under nitrogen at 50 C for 24 hours. The film samples was then washed with tetrahydrofuran (THF) (3xl5mL), tert-butyl alcohol (2xl5mL), toluene (2xl5mL) and dried under vacuum (10 hours). The film was wrapped around the cork, and then sealed with a heat gun.

  • the cork was dipped into a solution consisting of 75% Polyvinylidene chloride and 25% polymethylhydrogen siloxane emulsion. The coating was then cured in an oven at 38 C for 1 hour.
  • Corks can be rinsed or soaked with hot or cold water, alcohol, or a mixture of both water and alcohol, before the coating is applied. This reduces the occurrence of taint and other unwanted odours by washing away any taint compounds already on the surface of the cork. It is thought that any surface taint could mix with the coating during the coating process and remain on the surface of the coating, thus contributing to, rather than preventing, the taint problem. Accordingly, it is preferable to carry out a washing procedure, eg as in Example A, B, C or D below, prior to coating corks. The corks are then dried, eg in an oven at 40 C for 24 hours, prior to being coated.
  • a washing procedure eg as in Example A, B, C or D below
  • Corks spiked with lOOmg/L of TCA in absolute ethanol were arranged in a single layer and passed through streams of hot water for 30 seconds and then allowed to dry.
  • Corks spiked with lOOmg/L of TCA in absolute ethanol were arranged in a single layer and passed through streams of liquid containing cold water and absolute ethanol and then allowed to dry.
  • Corks spiked with lOOmg/L of TCA in absolute ethanol were completely immersed in a solution of hot water for 30 minutes and allowed to dry.
  • Corks spiked with lOOmg/L of TCA in absolute ethanol were completely immersed in a solution containing a mixture of cold water and absolute ethanol.
  • the simplest application method is dip coating, involving a container filled with the coating formulation into which the substrate (such as a cork) is immersed and then withdrawn.
  • a typical dip coating unit consists of a bath, filled with the coating formulation, and a mechanism on which the substrate is mounted for immersion and withdrawal. It is often necessary to circulate and filter the coating to maintain a homogeneous mixture.
  • a fixing mechanism must be designed to ensure the proper orientation of the substrate during immersion into and withdrawal from the fluid.
  • the fluid is atomised into fine droplets for application to the substrate.
  • the size of the droplets formed during atomisation can be controlled by such properties as fluid flow, fluid pressure, air pressure, solution viscosity, and surface tension.
  • a number of different nozzle designs are used in industry, such as compressed air spray nozzles, airless spray nozzles, and hot spray systems.
  • Slot coating and curtain coating are more appropriate techniques for a continuous operation.
  • the methods involve a stationary die, which delivers a layer of coating onto a substrate moving beneath it.
  • the difference between the methods is in the way that the coating is transferred from the die to the moving substrate.
  • the coating is spread by the slot method when the die slot is close to the substrate; but changing the orientation of the die slot relative to the conveyor and allowing the formulation to cascade is referred to as curtain coating.
  • Multiple slots in the die face or converging feed to a single slot can produce multilayer coatings.
  • Roll coating is another method used in continuous manufacturing operations primarily for coating films.
  • a substrate is fed between two rotating cylinders, while simultaneously directing the coating into the space between the cylinders.
  • Formulation viscosity, speed of the substrate, coating flow rate, and distance between the rolls all contribute to coating thickness and uniformity. Although these systems are limited in the types of substrate that can be coated, they can rapidly produce a very uniform product.
  • UV light One of the most popular techniques used to initiate cross-linking is irradiation by ultraviolet light. It can be a more rapid process than thermal curing, sometimes taking less than a second to act. Very little heat is generated during the exposure, which can often be carried out at room temperature.
  • Electron beam (E-beam) radiation shares the same benefits as UN radiation, without the need for a photoinitiation.
  • the exposure forms free radicals that cause the chain reaction.
  • Cycle times for Y-ray systems can be longer than for E-beam, at least for conventional polymer matrices, but for curing hydrophilic coatings this does not present a problem.
  • Thin polymer films can be deposited onto various substrates through the use of plasma polymerisation.
  • a plasma is generated by means of electron excitation, with a gas mixture and an organic monomer.
  • These thin films can be between a few hundred angstroms to a micrometre in thickness.
  • Cross-linking density is usually greater than in conventionally applied coatings, and thin films exhibiting good adhesion can be laid down on virtually any type of substrate.
  • Surface grafting techniques incorporate some of the same general concepts as coating and curing operations but may be more appropriate where exceptionally thin surface layers are desired. Points that distinguish surface grafting from "wet" coating operations are related mainly to the formation of the modified surface layer and the general molecular structures that result.
  • a continuous phase is formed by the reactions of the monomeric or polymeric ingredients, and is adhered to the substrate surface through secondary molecular interactions such as hydrogen bonding, London dispersive forces or acid-base interactions. Primary covalent bonding is also possible if the substrate has been pre-treated with molecular groups.
  • the monomeric (or polymeric with reactive end groups) components react directly with a polymeric substrate.
  • Various forms of radiation such as UV, electron beam, and Y-rays, may be used to cause the formation of peroxide groups on the polymer surface. These are unstable so decompose, and cause initiation of polymerisation in the process.
