Description

Coating a layer containing an antioxidant, a container for consumer goods

The present invention relates to a container comprising a coating comprising an antioxidant, in particular towards the interior of the container. The container is in particular filled with consumer goods, in particular food, beverage or other food, personal care or medical products. It specifically has an inner coating comprising an antioxidant. The invention further relates to a method of making such a container, to the use of the container for storing consumer goods, and to the use of an antioxidant as an additive to the coating of such a container.

For centuries, consumer goods have been stored in a variety of containers, including wood, hides, pottery and leather.

In the past decade, alternative packaging forms, such as metal containers, plastic containers such as polyethylene (PE), polypropylene (PP), polyethylenetetraphthate (PET) or other The popularity of polymers and their blends and paper or cardboard containers has increased. It offers the advantage of less weight, however its properties are not suitable for long-term storage in many cases, especially for products that are sensitive to oxidation.

This oxidation-sensitive commodity is associated with consumer goods (consumables) in all areas, especially foods such as food and beverages, but also pharmaceutical products or drugs, medical With veterinary products and cosmetics and personal care products. In many cases, problems arise also due to the relatively active nature of these goods or products. These problems occur in both liquid and solid consumer goods. As a result of the interaction of the product with the container or the compound entering the container (e.g., oxygen), the quality of the product is compromised and/or the shelf life of the consumer product and the stability of the storage are degraded.

In order to ensure product integrity, longevity and compliance with consumer requirements for sustainable packaging, and to maintain the quality of the product under a variety of global storage and transportation conditions, the development of a strong packaging system, especially for refined products (consumption) In terms of sex goods, it is considered to be needed.

As globalization and the global market demand for consumer goods increase, it is necessary to maintain the integrity and stability of these goods while transporting them globally. In addition, due to the current global economic situation, manufacturers of consumer goods are forced to package their products in several countries around the world. These products become sensitive to a variety of regional conditions, including water quality and chemical composition, climatic conditions, etc., all of which have a significant potential impact on product integrity, stability and longevity.

For example, products such as wine that are extremely easy and constantly interacting with their environment need to maintain their internal chemical balance so that the integrity of the product can be delivered to the consumer in a complete and sustainable manner as the brewer wishes. As the global market opens, brewers hope to deliver their products to consumers around the world in the form of the wine they make. In a globalized market, this goal is extremely difficult with changing weather conditions, temperature fluctuations, the quality of the logistics system and the ability to maintain the integrity of the wine until it reaches the consumer.

In addition, for a complete wine packaging system and a product that provides a precise balance of global transportation, the wine can be transported from the brewer to the consumer, regardless of Where the fee is located, maintaining its complete balance and appearance and stable inventory life (up to 12 months) is already commercially long-lasting, but it is also necessary to reduce its overall carbon footprint to The minimum is friendly to the environment.

As the demand for wine in the global market increases, the need to maintain wine integrity and safety during global transportation and an additional application of a more environmentally stable beverage package is needed. The need for a closed loop, fully recyclable product capability to develop an integrated wine and beverage packaging system that encompasses a wide range of products that are transported globally through a variety of storage and transportation conditions has emerged.

In order to meet the increasing environmental awareness of consumers and the requirements for product integrity, there is a need for aluminum containers that are free of canned contamination, so that consumers can safely bring high-value goods such as wine from other sources. Packaging systems that are less environmentally friendly are over-represented in this environmentally friendly form of packaging.

Consumer assurance relies on factors such as product packaging that does not have tin flavor (canned contamination) in aluminum containers, stability of inventory life, and product integrity that needs to be maintained through product packaging in aluminum containers.

Traditionally, canners have applied paint to the inside of an aluminum can to form a barrier between the product and the can body prior to being filled. In order to allow the beverage to be maintained in an aluminum container for a short period of 3-6 months, these conventional lacquers are applied to the inside of the beverage can.

The general methods of construction and coating used by beverage can/container manufacturers today do not address wine issues and wine product shelf life stability and product integrity. Many manufacturers of beverage cans or other beverage containers are experiencing deterioration in product integrity, including reduced flavor characteristics, reduced freshness, product taste, aroma and color changes, and can coating failure. The defeat leads to perforation and deterioration. Finally, internal product collapses may occur, further jeopardizing the reputation of aluminum containers as a premium beverage container and environmental alternative.

It is generally accepted in the industry that it is known that when wine and wine products are filled into cans/cans using the current general paint, etc., within a short period of time (6 months) these products are damaged and accompanied by loss of product integrity. The internal guidelines owned by the beverage can manufacturer are only recommended for a stable inventory life of 6 months, after which it is guessed based on the individual product's time test evaluation.

Manufacturers of aluminum beverage containers have received significant consumer complaints about canned beverages that have "tinky", "oxidized" or "boring", "no taste" or "flat taste". This is because the product itself suffers from a loss of integrity through the interaction between the product and the coating and the aluminum container through the coating or even the disintegration of the paint. This results in a product that is considered to be inferior in the aluminum container when the consumer compares it to the same wine in the glass package, especially for high value products such as wine.

The perceived difference in taste creates a negative perception of the potential of aluminum containers for the delivery of wines with integrity and consistent quality and wine-based products. Because glass is less recyclable than aluminum, it has a greater negative impact on the environment.

In today's highly competitive market, manufacturers are looking for ways to reduce costs and remain competitive in the marketplace. Beverage manufacturers demand lower-priced packaging options from their suppliers, forcing canners to use the least amount of aluminum and lacquer to provide a competitive product to their customers.

Since the mid-1990s, there has been a clear shift towards the use of thinner standard aluminum to make aluminum cans. Aluminum beverage container manufacturers are looking for ways to reduce the cost of aluminum beverage containers, and one way to achieve this is to reduce the aluminum thickness of the aluminum rolls used to make the cans.

The action of moving to a thinner aluminum thickness reduces overall cost while also reducing the amount of metal required and the energy required to make a can. However, these thinner cans present some significant problems with the products they carry, which is a big consideration for cans and beverage manufacturers and consumers. It is more susceptible to external damage and lacquer damage during manufacturing, filling, packaging, storage, transportation and throughout the supply chain.

Treatment of these products may result in damage through dents and, depending on their location on the can, may also cause damage to the internal can coating (cracking and breaking), while subsequent wines cause product contamination of the aluminum material. With deterioration. Such damage has the potential to disrupt the transportation of the entire product via the leakage of the aluminum container from the surrounding product and cause significant commercial damage.

In addition, due to today's global economic conditions, beverage manufacturers are forced to package their products in several countries around the world. These products are susceptible to a variety of regional conditions, including water quality and chemical composition, climatic conditions, etc., all of which have a significant potential impact on product integrity, stability and longevity.

Preferably, the antioxidant used has a Trolox equivalent unit of at least 0.1, preferably at least 0.2, preferably at least 0.5, preferably at least 0.75.

Further, the coated container with the antioxidant unexpectedly effectively suppresses or minimizes the deterioration of the quality of the packaged consumer goods, specifically, the quality deterioration due to oxidation.

The container according to the invention unexpectedly helps to maintain and even promote the quality and/or longevity of the consumer product. Surprisingly, we have found that the use of antioxidants in the containers of the present invention not only provides protection to the consumer material relative to the container material, but it also enhances the benefits within the consumer product. Without assuming, without limitation, a theory that an antioxidant involves a beneficial interaction between the container (inner surface) and the consumer product, and may also neutralize the replacement of harmful substances that should otherwise occur on the surface of the container wall. For example, oxygen, other oxides or corrosive substances.

The present invention causes any interaction or reaction with a packaging material or with a compound present in the container, such as air or, in particular, oxygen, causing degradation or decomposition of the packaging material and/or the packaged product, and ultimately resulting in such consumption. The packaging of corrupt consumer goods for sexual goods is effective.

If the consumer product reacts with the inner coating of the container, it causes a problem of spoilage of the consumer product caused by the packaging material, and therefore it is important to prevent degradation and decomposition of the packaging material.

The inventors have surprisingly found that a portion of the antioxidant applied as the inner wall of the container protects and prevents such degradation and decomposition.

According to an embodiment of the invention, without being bound by theory, it is assumed that the antioxidant present in the coating of the container may be on the surface of the coating that faces and contacts the consumer product, And in the coating (which may also act as a reservoir for long-term release of the antioxidant) and from the coating to the consumer product as an active ingredient in the consumer product.

It has been observed that as part of the present invention, the antioxidant may have additional desirable functions, such as inhibiting undesired reactions or degradation of the consumer commodity within the container. Therefore, for example, excessive growth of microorganisms can cause deterioration of the taste, aroma, and integrity of the food. In addition, metabolites of microorganisms can exacerbate the problem of rupture of the packaging material.

By creating a positive barrier to antioxidants, we were surprised to find that it protects the consumer goods and increases its stability and longevity.

According to one aspect of the invention, the presence of an antioxidant is beneficial in the coating of the container prior to the addition of a consumer product to the container. According to this particular embodiment, the container of the present invention refers to an empty container prior to filling the consumer product. According to a specific embodiment, the container of the present invention is an unused container, i.e., never used to fill a consumer product. This provides a protective barrier to the inner wall of the container as described above, for example from the beginning, i.e., when filling the container, resists the high activity, corrosivity, acidity and oxidation of the consumer product. The composition of the character, as well as providing a protective and advantageous surface with the coating. In accordance with an embodiment of the present invention, this initial protection is particularly important to maintain the integrity of the coating from the first contact with the consumer product, but also to protect the long-term quality and perfection of the consumer product.

In a preferred embodiment of the invention, the coating layer comprises an antioxidant having a concentration of at least 0.0001% by weight, preferably at least 0.001% by weight, more preferably at least 0.01% by weight, still more preferably at least 0.1% by weight. The percentage, more preferably at least 1 weight percent, still more preferably at least 10 weight percent, still more preferably at least 30 weight percent.

In another preferred embodiment of the invention, the coating layer comprises a concentration of up to More than 70% by weight of the antioxidant, preferably up to 30% by weight, more preferably up to 10% by weight, still more preferably up to 1% by weight, still more preferably up to 0.1% by weight, still more preferably up to 0.01% by weight More preferably, it is at most 0.001% by weight.

In a particularly preferred embodiment of the invention, the coating layer according to the invention comprises an antioxidant in a concentration of from 0.0001 to 10% by weight, in a more preferred embodiment from 0.1 to 5% by weight, It is preferably from 0.5 to 1% by weight, and in another more preferred embodiment, from 0.001 to 0.05% by weight, preferably from 0.005 to 0.01% by weight.

According to a particular embodiment of the invention, the above weight percentage ranges are based on the total weight of the antioxidant-containing coating layer. If more than one coating layer is present in the container, in accordance with an embodiment of the invention, the above weight percentages are based on the total weight of all coating layers. According to another embodiment of the invention, the above weight percentage ranges are based on the total weight of the coating layer containing only the antioxidant.

According to one aspect of the invention, the concentration of the antioxidant may also vary across the cross-section of the coating layer. For example, according to a particular embodiment, the concentration of the antioxidant at or near the surface of the coating layer facing the consumer product may be higher than the portion of the coating that is further from the surface. As such, in accordance with an embodiment of the present invention, it is possible to enhance the protective effect of the surface of the coating layer, for example, in an unused container prior to filling the consumer product, such that when the consumer product is filled into the container There is an advantageous protective layer inside. According to another embodiment, a longer concentration reservoir of antioxidants may also be provided in the coating layer in an opposite concentration arrangement.

The container according to the present invention provides an improved method of packaging its merchandise by manufacturers and packagers of consumer goods.

The internal barrier containing the antioxidant and the application method thereof can be an integral packaging system As part of the system, the system has the ability to be applied to any container during normal container manufacturing.

Furthermore, the container according to the invention can transport the end product containing sensitive consumer goods in a non-refrigerated shipping container, thus reducing the carbon footprint.

In a preferred embodiment, the container comprises or is made of a metal, a polymeric material such as a plastic material, paper, paperboard, glass, or a combination thereof, and in a more preferred embodiment is aluminum. The present invention is effective for the storage of any of the consumer goods referred to herein, including such acid, corrosive, oxidizing, or capable of reacting with the packaging material in any manner, and the presence of such environmental factors The compound in the container is sensitive. As noted above, the container used herein encompasses any packaging or packaging material for consumer goods in a rigid or resilient form. The container may have a suitable form or shape for packaging individual items. The container may be, for example but not limited to, cans, bags, cans, cans, troughs, bowls, bottles, buckets or the like. According to a specific embodiment, the container is a package for a drug. According to a specific embodiment, the container may also be in the form of a bubble wrap and the antioxidant may be present on the metal foil and/or on the plastic film of the bubble wrap.

In a preferred embodiment of the invention, the coating acts as a bi-directional barrier. A two-way barrier is understood in the context of the present invention to not only protect the consumer product from undesired interactions with the packaging material, but also to degrade or alter the quality of the consumer product; in addition, the barrier should also Protecting the packaging material from undesired interactions with the consumer product creates a possible hazard to the container or its integrity.

According to several aspects of the invention, the containers, steps and applications according to the invention may in particular reduce the chance of food poisoning (especially from canned food) or increase the shelf life of the product (life and stability of the product). It can also help to achieve a variety of consumer-oriented packaging A variety of suitable transportation conditions for several global climatic conditions. It may further reduce the need for preservatives, such as salt/sodium based preservatives, or for example sorbic acid as a preservative in canned foods. It can also, for example, prevent harmful corrosive effects on the container or its lining. In many cases, they may maintain or stabilize the natural flavor or increase the natural flavor of the food as a consumable commodity. The formation of free radicals can be achieved by, for example, reducing/eliminating the formation of bacteria that are useless in food. Therefore, the chance of infection can be reduced. For pharmaceutical products, it can increase its stability and quality.

According to a particular embodiment, in principle all coating compositions or lacquers known to those skilled in the art can be used as coating layers in the present invention. Examples of the general methods of preparation and the application of the exemplary coatings are disclosed in European Patent Application Publication No. EP 2457840 A1 ""Packaging Materials 7. Metal Packaging for Food" (ILSI European Special Committee for Packaging Materials) , September 2007, can be found at https://europa.eu/sinapse/sinapse/index.cfm?fuseaction=lib.attachment&lib_id=C5C03DA0-ED72-0D54-309D55AA14F6C62F&attach=LIB_DOC_EN) or "Preliminary Industry Description: Canned Metals Manufacturing - Surface Coating" (US Environmental Protection Agency publication, September 1998, available at http://www.epa.gov/ttnatw01/coat/mcan/pic-can.pdf ).
