Description

Technical Field

[0001] This invention relates to an oxidation treatment of the surface color and gloss of metal components for cosmetic storage containers. In particular, it relates to a multi-layered oxidation process for color and gloss on the surface of metal components for cosmetic storage containers. Background Technology

[0002] The surface treatment of metal components in cosmetic storage containers (such as lipstick tubes and powder compacts) not only needs to meet functional requirements such as corrosion resistance and wear resistance, but also bears an important decorative mission, being key to enhancing the product's appearance and aesthetics. Currently, the surface treatment processes for metal components in this field mainly rely on the following two technical approaches. The first common process involves first anodizing the metal component (such as aluminum alloy) to form an oxide film on its surface, then obtaining a base color through dyeing, and finally using printing technology (such as screen printing) to print specific patterns onto the oxide film surface.

[0003] However, this process has obvious drawbacks: the ink used for printing has a significantly different texture from the luster and feel of the metal substrate itself, making it difficult to realistically imitate the unique luster of metal, resulting in a stiff decorative effect of the pattern and a lack of sophistication.

[0004] Furthermore, the introduction of inks has led to the problem of material diversity. When recycling waste products, it is necessary to separate the ink layer from the metal substrate, which increases the complexity and cost of the recycling process. In addition, some inks may contain environmentally unfriendly chemicals, which goes against the trend of green and environmentally friendly development.

[0005] The second process involves first creating a pattern on the metal blank using laser engraving or similar methods, and then performing overall anodizing and dyeing.

[0006] While this method avoids the use of ink, its inherent drawback is that after oxidation and dyeing, the overall gloss color of the component tends to be consistent with the gloss color of the laser-engraved pattern area, making it impossible to form an effective visual distinction. This results in low contrast between the pattern and the background, which also weakens the aesthetic appeal and sense of layering of the decoration.

[0007] In conclusion, existing surface treatment technologies have significant shortcomings in meeting the comprehensive demands of cosmetic packaging for high-quality metallic textures, complex color effects, and environmental friendliness. Therefore, there is an urgent need for a new technological solution that can achieve flexible, exquisite, and environmentally friendly surface decoration effects with a variety of colors and glosses while preserving the excellent texture of the metal itself. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an oxidation process for the surface of metal parts of cosmetic storage containers that can achieve flexible, exquisite and environmentally friendly surface decoration effects with multiple colors and glosses.

[0009] The technical solution adopted in this invention is: an oxidation process for multi-layered color and gloss on the surface of metal parts of cosmetic storage containers. This process involves performing several oxidation treatments and printing processes on the surface of the metal parts of the cosmetic storage container to create a multi-layered metallic gloss and color pattern on the product surface. Specifically, the process includes the following steps:

[0010] 1) Formed blank metal parts, the surface of the blank is the original color of the metal blank;

[0011] 2) Perform the first oxidation process to apply the first gloss and color to the original color of the metal blank on the surface of the blank metal part;

[0012] 3) Print a first protective ink at a set position on the surface of the blank metal part with the first gloss and color, so as to cover and protect the first gloss and color at the set position by the first protective ink.

[0013] 4) Perform an alkaline washing process to remove the first gloss and color adhering to the blank metal parts, revealing the original color of the metal blank. At this time, since the first protective ink does not react chemically with the alkaline washing process, the first protective ink on the blank metal parts and the first gloss and color covered by the first protective ink continue to exist.

[0014] 5) Perform a second oxidation process to attach a second gloss and color to the original color of the metal blank on the surface of the blank metal part. Since the first protective ink does not react chemically with the oxidation process, the first protective ink and the first gloss and color covered by the first protective ink on the surface of the blank metal part continue to exist.

[0015] 6) Print a second protective ink at a set position on the surface of the blank metal part with the second gloss and color attached. The second protective ink is used to cover and protect the second gloss and color at the set position.

[0016] 7) Perform an alkaline washing process to remove the second gloss and color attached to the blank metal parts, revealing the original color of the metal blank. At this time, since the first protective ink and the second protective ink do not react chemically with the alkaline washing process, the first protective ink and the first gloss and color covered by the first protective ink, as well as the second protective ink and the second gloss and color covered by the second protective ink, continue to exist on the blank metal parts.

[0017] 8) A third oxidation process is carried out to attach a third gloss and color to the original color of the metal blank on the surface of the blank metal part. Since the first protective ink and the second protective ink do not react chemically with the oxidation process, the first protective ink and the first gloss and color covered by the first protective ink, as well as the second protective ink and the second gloss and color covered by the second protective ink, continue to exist on the surface of the blank metal part.

[0018] 9) Print a third protective ink at a set position on the surface of the blank metal part with the third gloss and color attached. The third protective ink is used to cover and protect the third gloss and color at the set position.

[0019] 10) Perform an alkaline washing process to remove the third gloss and color adhering to the blank metal parts, revealing the original color of the metal blank. At this time, since the first, second, and third protective inks do not react chemically with the alkaline washing process, the first, second, and third protective inks on the blank metal parts, as well as the first, second, and third gloss and color, the second, and third gloss and color covered by the first, second, and third protective inks, continue to exist.

[0020] 11) A fourth oxidation process is performed to apply a fourth gloss and color to the original color of the metal blank on the surface of the blank metal part. Since the first, second and third protective inks do not react chemically with the oxidation process, the first, second and third protective inks on the surface of the blank metal part, as well as the first, second and third gloss and color, the second and third gloss and color covered by the first, second and third protective inks, continue to exist.

[0021] 12) The first, second and third protective inks on the surface of the blank metal parts are removed by the ink removal process, revealing the first, second and third gloss and color, along with the fourth gloss and color, to form a product with multiple gloss and color effects arranged side by side.

[0022] The cosmetic storage container of this invention utilizes a multi-layered oxidation process on the metal components to achieve various colors and lusters. This process gives the surface patterns a metallic sheen, and the juxtaposition and nesting of different colors and lusters enhances aesthetics and contrast. The manufacturing process is simple, reliable, and suitable for production. The use of a single metal component is environmentally friendly and recyclable. In the past, consumer spending primarily focused on meeting basic needs. However, with advancements in society and increased material wealth, consumers are now seeking higher-quality, more personalized goods and services, creating a vast market for personalized consumption. As people's aesthetic sensibilities become more sophisticated, product design must cater to popular tastes and the pursuit of individuality, such as through the combination of different colors and lusters. This demand allows for the creation of patterns with various lusters and colors to meet market needs, enhancing the product's perceived quality and aesthetics, and facilitating sales.
