Description

塗覆含抗氧化劑之層、用於消費性商品之容器 Coating Antioxidant-Containing Layers, Containers for Consumer Goods

本發明關於一種包含一含抗氧化劑之塗層的容器,具體而言是朝向該容器的內部。該容器具體而言係填充有消費性商品,具體而言為食物、飲料或其他食品、個人護理或醫藥產品。其具體而言具有一包含抗氧化劑的內塗層。本發明進一步涉及製備此容器的方法、使用所述容器以儲存消費性商品的應用及使用抗氧化劑作為添加劑添加至這種容器的塗層的應用。 The present invention relates to a container comprising an antioxidant-containing coating, in particular towards the interior of the container. The container is in particular filled with consumer goods, in particular food, beverages or other food, personal care or medicinal products. In particular, it has an inner coating containing antioxidants. The present invention further relates to a method of making such a container, the application of using said container to store consumer goods, and the use of an antioxidant added as an additive to a coating of such a container.

數個世紀以來,消費性商品已被儲存於各種容器中,包括木材、獸皮、陶器以及皮革。 For centuries, consumer goods have been stored in a variety of containers, including wood, hides, pottery, and leather.

在過去十年中,替代的包裝形式,例如金屬容器、塑膠容器如以聚乙烯(polyethylene,PE)、聚丙烯(polypropylene,PP)、聚對苯二甲酸乙二酯(polyethylenetetraphthate,PET)或其他聚合物及其混合物所製成者及紙或紙板容器的普及性增加。其提供了較少重量的優點,然而其特性在很多情況下,特別是是對氧化作用敏感的商品而言,並不適合長期儲存。 Over the past decade, alternative packaging forms, such as metal containers, plastic containers such as polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET) or other The popularity of those made of polymers and their blends and of paper or cardboard containers has increased. It offers the advantage of less weight, however its properties are in many cases unsuitable for long-term storage, especially for commodities that are sensitive to oxidation.

這種對氧化作用敏感的商品與所有領域的消費性商品(消耗品)相關,特別是食品,例如食物與飲料,但也包括醫藥產品或藥物、醫療 與獸醫製品及化妝品與個人護理產品。在許多情況下,也因這些商品或產品的相對活躍的特性而產生問題。這些問題在液體與固體消費性商品中皆出現。產品與容器或進入該容器的化合物(例如氧氣)交互作用的結果是,該產品品質受損及/或該消費性商品的使用期限與儲存之穩定性減損。 This oxidation-sensitive commodity is relevant to all areas of consumer goods (consumables), especially food, such as food and beverages, but also medicinal products or pharmaceuticals, medical and veterinary products and cosmetic and personal care products. In many cases, problems also arise due to the relatively active nature of these commodities or products. These problems arise in both liquid and solid consumer goods. As a result of the interaction of the product with the container or a compound (eg, oxygen) entering the container, the quality of the product is compromised and/or the shelf life and storage stability of the consumer commodity is compromised.

為了確保產品完整性、使用壽命以及符合消費者對可持續包裝的要求,以及在各種全球儲存與運輸條件之下維持該商品品質的需求,一個強大包裝系統的開發,特別是針對精緻產品(消費性商品)而言,被認為是需要的。 In order to ensure product integrity, longevity and compliance with consumer demand for sustainable packaging and the need to maintain the quality of the product under various global storage and transport conditions, a robust packaging system was developed, especially for delicate products (consumer Sexual Goods) are considered required.

隨著全球化以及全球市場對消費性商品的需求增加,需要在全球性運輸這些商品的同時維持其完整性與穩定性。此外,由於現今的全球經濟狀況,消費性商品的製造商被迫在全球各地的數個國家中包裝其產品。這些產品在製造時變得對各種地區性條件很敏感,包括水質與化學成分、氣候條件等,所有的條件對產品完整性、穩定性以及壽命具有顯著潛在的影響。 With globalization and the increased demand for consumer goods in the global marketplace, these goods need to be transported globally while maintaining their integrity and stability. Furthermore, due to today's global economic conditions, 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 during manufacture, including water quality and chemical composition, climatic conditions, etc., all of which have a significant potential impact on product integrity, stability, and longevity.

例如,如葡萄酒這種極易且不斷地與其環境交互作用的產品,需要維持其內部的化學平衡,使產品的完整性可如釀酒商所願而被完整保持地運送給消費者。隨著全球市場開放,釀酒商希望可將他們的產品以其製造之葡萄酒的樣貌被運送給全球消費者。在全球化市場中,隨著變化的天氣條件、溫度波動、物流系統的品質與維持該葡萄酒的完整性直至到達消費者為止之能力,該目標是極為困難的。 For example, a product such as wine that interacts easily and constantly with its environment needs to maintain a chemical balance within it so that the integrity of the product can be delivered to the consumer intact as desired by the winemaker. As the global market opens up, winemakers want to be able to ship their products to consumers around the world in the form of the wines they make. In a global market, 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, this goal is extremely difficult.

此外,對於一完整的葡萄酒包裝系統以及一種提供全球運輸的精確平衡的產品使得葡萄酒的運輸可以自釀酒商至消費者,且不論該消 費者位於何處,都維持其完整的平衡及外觀以及穩定的庫存壽命(達到且超過12個月)的需求,已是商業上長久所需,但也要對將其整體的碳足跡減至最低以對環境友善。 In addition, for a complete wine packaging system and a precisely balanced product that provides global shipping, wine can be shipped from the winemaker to the consumer regardless of the consumer. The need for consumers to maintain their intact balance and appearance and stable inventory life (up to and beyond 12 months) wherever they are located is a long-term business need, but also to reduce their overall carbon footprint to Minimum to be environmentally friendly.

隨著全球市場對葡萄酒的需求的增加,在全球性運輸時維持葡萄酒完整性與安全性以及一種對環境更穩定的飲料包裝的附加應用是被需要的。對於發展一整合的葡萄酒與飲料包裝系統,裝載透過各種儲存與運輸條件而全球性運輸的多樣產品範圍之一封閉迴路、完全可回收的之產品能力的需要已經出現。 As the demand for wine in the global market increases, the maintenance of wine integrity and safety during global transportation and an additional application for more environmentally stable beverage packaging is required. The need has arisen for the development of an integrated wine and beverage packaging system, the ability to carry a closed loop, fully recyclable product of a diverse product range that is shipped globally through a variety of storage and shipping conditions.

為了滿足日益增加的環境意識消費者的期待加上對產品完整性的要求,需要沒有罐頭污染風險的鋁製容器,以使消費者能安心地將如葡萄酒這種高價值商品從其他目前具有之對環境較不友善的包裝系統過度到這種對環境友善的包裝形式。 In order to meet the expectations of increasingly environmentally conscious consumers coupled with demands for product integrity, aluminum containers without the risk of contamination from cans are needed to allow consumers to confidently transfer high-value commodities such as wine from other currently available Less environmentally friendly packaging systems are overdue to this environmentally friendly form of packaging.

消費者保證係依賴例如在鋁製容器中沒有錫味(罐頭污染)的產品包裝、庫存壽命穩定性以及在鋁製容器中透過產品包裝而需要被維持的產品完整性等因素。 Consumer assurance relies on factors such as product packaging free of tin odor (can contamination) in aluminum containers, shelf life stability, and product integrity that needs to be maintained through product packaging in aluminum containers.

傳統上,罐頭製造商使用漆來塗覆於鋁罐的內側,以在被填充之前形成一介於產品與該罐身之間的屏障。為了讓飲料可以在鋁製容器內維持3-6個月的短暫期間,這些傳統的漆被塗布在飲料罐的內側。 Traditionally, can makers have used paint to coat the inside of aluminum cans to form a barrier between the product and the can body before being filled. These traditional lacquers are applied to the inside of the beverage can in order to allow the beverage to remain in the aluminum container for a brief period of 3-6 months.

現在飲料罐/容器製造商使用的建構及塗布漆的一般方法並不涉及葡萄酒的問題以及葡萄酒產品庫存壽命穩定性與產品完整性。許多飲料罐或其他飲料容器的製造商正面臨產品完整性惡化,有些包括風味特性下降、新鮮度減損、產品的味道、香氣與顏色的改變,以及罐頭塗覆失 敗導致穿孔與變質。最後,可能發生內部產品崩壞,進一步危害鋁製容器作為優質飲料容器與環境替代方案的聲譽。 The general methods of construction and application of paint used by beverage can/container manufacturers today do not address wine issues and wine product inventory life stability and product integrity. Many manufacturers of beverage cans or other beverage containers are facing a deterioration in product integrity, some of which include loss of flavor properties, loss of freshness, changes in product taste, aroma and color, and loss of can coating. Failure leads to perforation and deterioration. Finally, internal product breakdown can occur, further jeopardizing the reputation of aluminum containers as a premium beverage container and an environmental alternative.

在業界一般認為,已知當葡萄酒與葡萄酒產品填充到使用現行一般漆的罐頭/瓶罐等之內,在一短暫期間內(6個月)這些產品會遭受損壞且伴隨產品完整性的喪失。飲料罐製造商擁有的內部指南只建議以6個月作為穩定的庫存壽命,而在此之後就是根據個別產品透過產品時間測試評估來猜測。 It is generally accepted in the industry that when wine and wine products are filled into cans/bottles etc. using current common paints, these products are known to suffer damage with concomitant loss of product integrity for a short period of time (6 months). Beverage can manufacturers have internal guidelines that only recommend a stable stock life of 6 months, after which it is guesswork based on individual product evaluations through product time testing.

鋁製飲料容器製造商收到顯著的消費者抱怨罐裝飲料喝起來「有錫味」、「氧化」或「乏味」、「沒有味道」或「平淡的味道」。這是因為透過產品與塗層及鋁製容器之間的交互作用,經過該塗層或甚至是某種程度漆的崩解,產品本身遭受完整性的喪失。其導致特別是針對高價值產品如葡萄酒而言,當消費者將之與玻璃包裝的相同葡萄酒相比時,消費者認為在鋁製容器中製造的產品是低劣的。 Manufacturers of aluminum beverage containers have received notable complaints from consumers that canned beverages taste "tinny," "oxidized," or "bland," "tasteless," or "bland." This is because the product itself suffers a loss of integrity through the disintegration of the coating or even the paint to some extent through the interaction between the product and the coating and the aluminium container. This results in products manufactured in aluminium containers being perceived by consumers to be inferior when compared to the same wine packaged in glass, especially for high value products such as wine.

感知味覺的差異造成對鋁製容器在運送具有完整性與一致品質的葡萄酒與以葡萄酒為基底的產品上的潛力之負面看法。因為玻璃可回收性不如鋁,如此一來對環境具有造成更大的負面的影響之間接效果。 Differences in perceived taste contribute to negative perceptions of the potential of aluminum containers for the delivery of wine and wine-based products with integrity and consistent quality. Because glass is not as recyclable as aluminum, it has the indirect effect of having a greater negative impact on the environment.

在今日的競爭激烈市場中,製造商尋找降低成本與在市場中保持競爭力的方法。飲料製造商向其供應商要求較低價的包裝選項,迫使罐頭製造商使用最少量的鋁及漆以提供一具有競爭力的產品予其客戶。 In today's competitive marketplace, manufacturers look for ways to reduce costs and remain competitive in the marketplace. Beverage manufacturers are demanding lower-priced packaging options from their suppliers, forcing canners to use a minimum amount of aluminum and paint to provide a competitive product to their customers.

自九十年代中期,已有明顯朝向使用較薄標準的鋁以製造鋁罐的轉變。鋁製飲料容器製造商尋找各種方法以減少鋁製飲料容器的成本,而達到此目標的一種方法是減少用於製造罐頭的鋁輥之鋁厚度。 Since the mid-nineties, there has been a marked shift towards the use of thinner gauge aluminium for the manufacture of aluminium cans. Manufacturers of aluminum beverage containers look for ways to reduce the cost of aluminum beverage containers, and one way to achieve this goal is to reduce the aluminum thickness of the aluminum rolls used to make the cans.

移至較薄鋁厚度的動作降低了整體成本,同時也減少了金屬用量與製造一個罐頭所需的能量。然而,這些較薄的罐頭出現對其所攜帶的產品的一些顯著問題,其對罐頭與飲料製造商及消費者而言是較大的考量。在製造、填充、包裝、儲存、運輸與整個供應鏈過程中,其更容易受到外部損害以及漆的損害。 The move to thinner aluminum thicknesses reduces the overall cost, while also reducing the amount of metal used and the energy required to make a can. However, these thinner cans present some significant problems with the products they carry, which are of great concern to can and beverage manufacturers and consumers. It is more susceptible to external damage and paint damage during manufacturing, filling, packaging, storage, transportation and the entire supply chain.

這些產品的處理可能導致經由凹痕而來的損傷,且視其在罐頭上的位置,可能也會造成內部罐頭漆的損傷(裂開與斷裂),而後續葡萄酒對鋁原料之暴露造成產品污染與變質。這樣的損害具有經由鋁製容器之洩漏感染周圍產品而破壞整個產品運輸的可能並造成顯著的商業損失。 The handling of these products may result in damage via dents and, depending on their location on the can, may also cause damage to the interior can paint (splits and breaks), and subsequent exposure of the wine to the aluminum stock may result in product contamination with metamorphism. Such damage has the potential to infect the surrounding product via a leak from the aluminum container, disrupting the entire product shipment and causing significant business losses.

此外,由於今日的全球經濟狀況,飲料製造商被迫在全球各地的數個國家包裝其產品。這些產品在製造時變得容易受各種地區條件的影響,包括水質與化學成分、氣候條件等,所有的條件對產品完整性、穩定性與壽命具有顯著潛在的影響。 Furthermore, due to today's global economic conditions, beverage manufacturers are forced to package their products in several countries around the world. These products become susceptible to a variety of regional conditions during manufacture, including water quality and chemical composition, climatic conditions, etc., all of which have a significant potential impact on product integrity, stability and longevity.

此外,帶有含有抗氧化劑的塗覆的容器意外地有效率地抑制或最小化包裝的消費性商品的品質惡化,具體而言是起因於氧化作用的品質惡化。 Furthermore, containers with coatings containing antioxidants are surprisingly effective at inhibiting or minimizing the deterioration of the quality of the packaged consumer goods, specifically due to oxidation.

根據本發明之容器意外地有助於維持且甚至是促進該消費性商品的品質及/或壽命。令人驚奇的是,我們發現在本發明之容器中使用抗氧化劑不僅對該消費性商品提供相對於容器材料的保護,且其增強了該消費性商品內的有益效果。非限制性地假設一理論,抗氧化劑涉及介於該容器(內表面)與該消費性商品之間有益的交互作用,且可能亦中和替換若非如此應出現在該容器壁的表面的有害物質,例如氧氣、其他氧化物或腐蝕性物質。 The container according to the present invention unexpectedly helps to maintain and even promote the quality and/or longevity of the consumable commodity. Surprisingly, we have found that the use of antioxidants in the containers of the present invention not only provides protection of the consumer product relative to the container material, but it enhances the beneficial effects within the consumer product. Hypothetically, without limitation, a theory that antioxidants are involved in a beneficial interaction between the container (interior surface) and the consumer commodity, and may also neutralize and replace harmful substances that would otherwise be present on the surface of the container wall , such as oxygen, other oxidizing or corrosive substances.

本發明對任何可能與包裝材料或與存在該容器內的化合物交互作用或反應,例如空氣或具體而言氧氣,造成該包裝材料及/或該被包裝商品的降解或分解,且最終導致該消費性商品的腐敗的消費性商品的包裝是有效的。 The present invention addresses any potential interaction or reaction with the packaging material or with compounds present in the container, such as air or in particular oxygen, resulting in the degradation or decomposition of the packaging material and/or the packaged commodity, and ultimately the consumption Packaging of spoiled consumer goods for sexual goods is effective.

若消費性商品與容器的內塗覆反應,會引起由包裝材料造成的消費性商品腐敗的問題,因此防止該包裝材料的降解與分解是重要的。 If the consumer product reacts with the inner coating of the container, the problem of spoilage of the consumer product caused by the packaging material may be caused, and thus it is important to prevent the degradation and decomposition of the packaging material.

本案發明人驚訝地發現,作為容器的內壁塗覆的一部份的抗氧化劑可以保護且防止這種降解與分解。 The inventors of the present invention have surprisingly found that antioxidants, which are part of the coating of the inner wall of the container, can protect and prevent such degradation and decomposition.

根據本發明之一具體實施例不受理論束縛地假設,存在於容器的塗層的抗氧化劑可能在該面對且接觸該消費性商品的塗層表面上,以 及在該塗層內(其可能亦作為抗氧化劑長期釋放的儲存庫)以及自該塗層遷移至該消費性商品中而在該消費性商品中作為活性成份。 Without being bound by theory, it is assumed in accordance with one embodiment of the present invention that the antioxidant present in the coating of the container may be on the surface of the coating facing and in contact with the consumer good, to and within the coating (which may also act as a reservoir for long-term release of antioxidants) and migrating from the coating into the consumer commodity as an active ingredient in the consumer commodity.

據觀察,作為本發明的一部份,抗氧化劑可能具有附加所欲之功能,例如抑制非期望的反應或在容器內該消費性商品的降解。因此,例如微生物的過度生長可以導致食品的口感、香味及整體性的惡化。此外,微生物的代謝產物可加重該包裝材料破裂的問題。 It is observed that, as part of the present invention, antioxidants may have additional desired functions, such as inhibiting undesired reactions or degradation of the consumer product within the container. Thus, for example, the overgrowth of microorganisms can lead to a deterioration of the taste, aroma and integrity of the food product. Furthermore, microbial metabolites can exacerbate the problem of cracking of the packaging material.

透過創造一種具有正面效果的抗氧化劑的屏障,我們驚奇地發現其保護該消費性商品且增加了其穩定性與壽命。 By creating a barrier of positive antioxidants, we have surprisingly found that it protects the consumer commodity and increases its stability and longevity.

根據本發明之一方面,抗氧化劑存在於將一消費性商品添加至該容器之前的該容器的塗層內係有好處的。根據此一具體實施例,本發明之容器係指在填充消費性商品前的空容器。根據一具體實施例,本發明之容器為未使用過的容器,即從未用於填充消費性商品。這種方式提供了該容器的內壁如上所陳之具有保護作用的屏障,例如自一開始,亦即在填充該容器之時,抵擋該消費性商品之具高活性、腐蝕性、酸性與氧化性的組成份,以及以該塗層提供具有保護性及有利的表面。根據本發明之一具體實施例,此一自始的保護對於自與該消費性商品第一次接觸開始保持該塗覆層完整特別重要,但也保護該消費性商品的長期品質與完美。 According to one aspect of the present invention, it is beneficial for antioxidants to be present within the coating of the container prior to adding a consumer product to the container. According to this embodiment, the container of the present invention refers to an empty container prior to being filled with consumer goods. According to one embodiment, the container of the present invention is a virgin container, ie, never used to fill consumer goods. This way provides a protective barrier for the inner wall of the container as stated above, eg from the very beginning, ie when the container is filled, against the highly reactive, corrosive, acidic and oxidizing properties of the consumer commodity components, and provide a protective and favorable surface with the coating. According to one embodiment of the present invention, this initial protection is particularly important to keep the coating intact from the first contact with the consumer product, but also to protect the long-term quality and integrity of the consumer product.

在本發明之一較佳具體實施例中,該塗覆層包含濃度為至少0.0001重量百分比的抗氧化劑,較佳為至少0.001重量百分比,更佳為至少0.01重量百分比,又更佳為至少0.1重量百分比,又更佳為至少1重量百分比,又更佳為至少10重量百分比,又更佳為至少30重量百分比。 In a preferred embodiment of the present invention, the coating layer contains an antioxidant at a concentration of at least 0.0001 wt %, preferably at least 0.001 wt %, more preferably at least 0.01 wt %, still more preferably at least 0.1 wt % percentage, still more preferably at least 1 weight percent, still more preferably at least 10 weight percent, still more preferably at least 30 weight percent.

在本發明之一尤佳之具體實施例中,根據本發明該塗覆層包含濃度為自0.0001至10重量百分比的抗氧化劑,在一更佳具體實施例中為自0.1至5重量百分比,較佳為0.5至1重量百分比,在另一更佳具體實施例中為自0.001至0.05重量百分比,較佳為0.005至0.01重量百分比。 In a particularly preferred embodiment of the present invention, the coating layer according to the present invention comprises an antioxidant in a concentration of from 0.0001 to 10 weight percent, in a more preferred embodiment from 0.1 to 5 weight percent, and It is preferably 0.5 to 1 weight percent, in another more preferred embodiment, from 0.001 to 0.05 weight percent, preferably 0.005 to 0.01 weight percent.

根據本發明之一具體實施例,上述重量百分比範圍係基於該含有抗氧化劑的塗覆層的總重量。若該容器中存在多於一塗覆層,根據本發明之一具體實施例,上述重量百分比的範圍係基於所有塗覆層的總重量。根據本發明之另一具體實施例,上述之重量百分比範圍係基於僅限含有抗氧化劑的塗覆層的總重量。 According to an embodiment of the present invention, the above weight percentage range is based on the total weight of the antioxidant-containing coating layer. If more than one coating layer is present in the container, according to an embodiment of the present invention, the above weight percentage ranges are based on the total weight of all coating layers. According to another embodiment of the present invention, the above weight percentage ranges are based on the total weight of the coating layer containing only the antioxidant.

根據本發明之一方面,橫越該塗覆層的橫切面,抗氧化劑的濃度亦可能不同。例如,根據一具體實施例,在或接近面對該消費性商品的塗覆層表面的抗氧化劑的濃度可能高於距離該表面較遠的塗層的部分。這麼一來,根據本發明之一具體實施例,可能增進該塗覆層的表面的保護效果,例如,在填充消費性商品之前在未使用的容器中,如此當消費性商品被填充到該容器內時就存在一有利的保護層。根據另一具體實施例,亦可呈現相反的濃度排列而可在該塗覆層中提供抗氧化劑的較長期儲存庫。 According to one aspect of the invention, the concentration of antioxidants may also vary across the cross-section of the coating. For example, according to one embodiment, the concentration of antioxidants may be higher at or near the surface of the coating facing the consumer article than in portions of the coating that are further from the surface. In this way, according to an embodiment of the present invention, it is possible to enhance the protective effect of the surface of the coating, eg, in an unused container before filling the consumer goods, so that when the consumer goods are filled into the container There is an advantageous protective layer inside. According to another embodiment, an inverse concentration arrangement may also be present to provide a longer term reservoir of antioxidants in the coating.

根據本發明之容器提供消費性商品的製造商與包裝商改進的包裝其商品之方法。 Containers according to the present invention provide manufacturers and packers of consumer goods with an improved method of packaging their goods.

該含有抗氧化劑內部屏障及其應用方法可為一整體包裝系 統的一部分,該系統具有在正常容器製造過程中可應用於任何容器的能力。 The antioxidant-containing internal barrier and its application method can be an integral packaging system As part of the system, the system has the capability to be applied to any container during the normal container manufacturing process.

此外,根據本發明之容器可在非冷藏的海運容器內運輸含有敏感消費性商品的終產物,因此減少碳足跡。 Furthermore, containers according to the present invention can transport end products containing sensitive consumer goods in non-refrigerated shipping containers, thus reducing the carbon footprint.
