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.
  • cork stoppers Accordingly, there have been numerous attempts to improve on natural cork stoppers, by coating or impregnating them.
  • the first cork coatings were simply lubricants such as paraffin and Vaseline. These merely 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 trichloro-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 trichloro-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.
  • a copolymer comprising a flexible component and a retentive component is applied as a surface coating or diffusion layer to a substrate for use in contact with food products or beverages, said flexible component being sufficiently flexible to allow the coated substrate to undergo compression and recovery (eg so as to allow a coated cork according to the present invention to be compressed and then to recover during the bottling process) and said retentive component being able to bind with or otherwise retain flavour-active or odour-active compounds (commonly known as taint compounds).
  • the flexible component of the copolymer may be silicon-based, but the copolymers of the present invention are not restricted to those comprising silicon-based monomers. Other flexible monomers providing the necessary requirements for the coating may also be used. Two or more copolymers may be blended together to achieve the desired properties.
  • the substrate may, for example, be a bottle closure (such as a cork), packaging and wrapping materials (such as packaging for cheese), or a bottle or other container.
  • a bottle closure such as a cork
  • packaging and wrapping materials such as packaging for cheese
  • the copolymer comprises a flexible (eg silicon-based) component and a retentive component that retains flavour-active or odour-active compounds.
  • This multi-component polymer structure acts as a partial physical barrier to the passage of gases and undesirable flavour-active or odour-active compounds, whilst having the physical properties (in particular, flexibility) required during the treatment and packaging processes.
  • the polymer coating or diffusion layer of the present invention will prevent any undesirable flavour-active or odour-active compounds migrating from a cork to an alcoholic beverage.
  • the copolymer is also selected for other advantageous properties, such as adhering strongly to the substrate and/ or penetrating into the surface of the substrate.
  • the copolymer 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 copolymer coating or diffusion layer will also be resistant to sulphur dioxide and changes in pH.
  • copolymers of the present invention may be graft, alternating or block copolymers, or mixtures thereof. Suitable copolymers are described in the following references:
  • copolymers examples include: polyvinylacetate (PVA) copolymers polyurethane copolymers and ionomers terephthalate copolymers styrene-acrylonitrile (SAN)/acrylonitrile-butadiene-styrene (ABS) copolymers

  • PVA and functionalised siloxanes (eg comprising SiH or amino groups) have been found to be particularly suitable components of the copolymers.

  • the cork was dipped into a solution consisting of 75% Polyvinylacetate emulsion and
  • the coating formulation consisted of a mixture of 75mL of polyvinylacetate 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 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.

  • 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.
  • thermal curing One of the most common methods for initiating the cross-linking of a polymer is by heating, and ovens can be incorporated into batch and continuous-mode systems.
  • the main disadvantage in thermal curing is the wasted thermal energy when only a small amount of the applied energy is transferred to the molecules. It can also be difficult to maintain a uniform temperature throughout the oven, so that curing may be uneven.
  • 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 UV 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.

Abstract

Dans un premier aspect, la présente invention concerne un procédé permettant de produire un revêtement ou une couche de diffusion sur un substrat (à savoir un bouchon) qui est mis en contact avec un produit alimentaire ou une boisson. Ce revêtement ou cette couche de diffusion empêche ou inhibe le passage (d'un bouchon vers une boisson alcoolisée) de composants donnant une odeur ou un goût (connu sous le nom de goût de bouchon). Ledit procédé consiste à appliquer à la surface dudit substrat une quantité efficace d'un copolymère comprenant un composant souple et un composant de rétention, ledit composant souple devant être suffisamment souple pour permettre au substrat imprégné de subir une compression et de reprendre élastiquement sa forme (afin de permettre au bouchon imprégné selon la présente invention d'être comprimé et reprendre ensuite sa forme élastiquement durant le processus de mise en bouteille) et le composant de rétention pouvant se lier aux composants donnant une odeur ou un goût ou retenir ces derniers. Dans un second aspect, la présente invention porte sur un substrat imprégné, et en particulier un bouchon synthétique imprégné ou un bouchon en liège naturel imprégné, produit selon ce procédé.
