Description

FIELD



[0001] The invention relates to a metal decorative product, and more specifically to a metal decorative product to be used for packaging of high-class goods such as wine and cosmetics and having metallic luster.

BACKGROUND



[0002] For the boxes of high-class goods such as wine, cosmetics and the like and the signs of high-class clothing, the design of metallic luster is sometimes used to show the high-class feel of commodities. As a technology for forming the metallic luster, paper laminated with metal foil such as aluminum foil, and paper laminated with metal evaporated film such as aluminum evaporated film were used in the past.

[0003] On the other hand, in order to carry out brand protection, tracking and tracing, and theft prevention for such high-class commodities, RFID tags, anti-theft tags and other devices that use electromagnetic waves are needed.

[0004] However, since materials using the above-described metal foil or metal evaporated film have the characteristics of reflecting or attenuating electromagnetic waves, it may have a adverse effect on the utilization of electromagnetic wave device. For example, Figure 5 is a schematic diagram showing the status where the parts pasted with electromagnetic wave device are contained in the existing metal decorative products, Figure 6 is an enlargement view of Area Y in Figure 5, and Figure 7 is a partial sectional view of the existing metal decorative product. Figures 5-7 are used to explain the effect on the communication of electromagnetic wave device. Metal foil is massively formed on the surface of substrate 101 of a wine packaging (which is a metal decorative product 100) as a metallic luster decoration coated packaging 301, and a printing layer is formed on the metallic luster decoration coated packaging 301. Further, a wine bottle is contained in the metal decorative product 100 as a part 200, on which an RFID tag is attached as an electromagnetic wave device 201. As shown by the arrow in Figure 5, the electromagnetic wave generated by the electromagnetic wave device 201 is reflected by the metallic luster decoration coated packaging 301, so that it cannot be radiated outside the metal decorative product 100. Therefore, it cannot be read with a reader (not illustrated).

[0005] In the past, in order to improve the adverse effects caused by the above-described metal foil or metal evaporation, various technologies to avoid forming a conductor surface continuously consisting of metal films were proposed.

[0006] For example, same problem exists in millimeter wave radar equipped on the marking part of cars. As a way to solve this problem, there is a method to form striped evaporation by controlling the evaporation of tin and other metals so as to solve the problem.

[0007] Further, in RFID, removel of metal part (i.e., demetallizing process), by means of etching, etc., is also adopted in products integrated with holograms. Thus, similar strategies are utilized.

[0008] By utilizing the above strategies, the continuity of the conductor surface can be destroyed so as to avoid the reflection or attenuation of electromagnetic waves.

[0009] US 2009/096609 A1 and CN 101 430 772 A relate to a packaging material with a printed decorative pattern and a RFID tag. An ink layer (such as an ink used for forming various decorative or advertising patterns or images) is printed on the internal side of a surface material a packaging material that comprises a surface material and a substrate.

SUMMARY


Technical Problem to be Solved by the Present Disclosure



[0010] However, the existing special evaporation technology or demetallizing process cannot be easily applied in manufacturing and cause cost increase due to the limitation of evaporated metal materials or the need for special manufacturing equipment.

[0011] The present invention is implemented in view of the above-mentioned problem, and its purpose is to provide a metal decorative product that can achieve metallic luster without affecting the performance of electromagnetic wave device and can be easily manufactured at a lower cost.

Technical Measures for Solving the Technical Problem

DETAILED DESCRIPTION



[0022] In the following descriptions, the first embodiment of the present disclosure will be illustrated with reference to Figures 1-3.

[First Embodiment]



[0023] Figure 1 is a schematic diagram for illustrating the structure of a metal decorative product involved in the first embodiment of the present disclosure. Figure 2 is an enlarged view of Area X shown in Figure 1. Figure 3 is a partial sectional view of the metal decorative product involved in the first embodiment of the present disclosure. As shown in Figure 1, a metal decorative product 10 is for example a box for wine or other high-class commodities, and contains therein a part 20 such as a wine bottle that is attached with an electromagnetic wave device 21 namely an RFID tag. Further, as shown in Figure 3, the metal decorative product 10 is composed of a substrate 11 such as paper. The surface of the substrate 11 has a metallic luster decoration coated packaging 31 formed thereon, a printing layer is formed on the metallic luster decoration coated packaging 31.

[0024] Figure 2 shows the status of the ink that forms the metallic luster decoration coated packaging 31 of the metal decorative product. As shown in Fig. 2, a large amount of metal powder 1 is dispersed in the ink 2 which forms the metallic luster decoration coated packaging 31, and the metal powder 1 is arranged in a tightly dense state. However, since there exists a large amount of insulating ink 2 in a state that covers the surface of the metal powder 1, the insulation between metal powders 1 can be basically ensured.

[0025] Also, as shown in Figure 2, there is situation where a portion of the metal powders tightly contact with each other to form a metal powder connection 3. In the past, such connection is actively used to further connect the metal powders 1 and the metal powder connections 3 so as to form conductive ink, and the conductive ink is printed to form a conductive loop. In contrast, the present disclosure tries to avoid this connection state and uses the ink 2 to make the metal powders 1 and the metal powder connections 3 separately insulated and independent with each other.

[0026] With the above-described structure a metallic luster can be achieved, and electromagnetic waves generated by the electromagnetic wave device 21 are allowed to pass through the metallic luster decoration coated packaging 31 and radiate outside the metal decorative product 10 as shown by the arrow in Figure 1 so as to be read by using a reader (not shown).

[0027] Further, in order to more efficiently allow electromagnetic waves generated by the electromagnetic wave device 21 to pass through, from the point of view regarding electrical performance, the metallic luster decoration coated packaging 31 formed by ink mixed with metal powder 1 and metal powder connection 3 made of metal powder 1 needs to separately and independently formed in a status where the electrical length is very short,. As a condition for the above-described electrical length, for example in the case where the electromagnetic wave device 21 is a radio wave device, it is required that the electrical length of the metal powder 1 and the metal powder connection 3 formed by the metal powder 1 shall be shorter enough than that of the radio wave device. Further, in the case where the electromagnetic wave device 21 is a magnetic device, it is required that the physical length of the metal powder 1 and the metal powder connection 3 formed therefrom shall be very short. Therefore, in any case, the electrical length of the metal powder 1 and the metal powder connection 3 formed by the metal powder 1 is preferably less than or equal to 5mm.

[0028] Below, a comparison between the metal decorative product illustrated in embodiments of the present disclosure and an existing product as a comparison example is described.

[0029] First of all, smoothness of the substrate surface shall be ensured to have metallic luster. Therefore, one side of a paperboard is coated to form a coating so as to form a coated paper. The paperboard, which is the substrate, is about 80g/m2 ~ 300g/m2. A coating surface of the above-described coated paper, which has a coating on one side, is coated with silver ink by means of relief printing so as to form a film shape and make a silver paper with metal effect. The silver ink contains scaly metal powder made of aluminum. The diameter of the particles in the aluminum powder in the above ink is about 2 µm ~ 50 µm, preferably less than or equal to 20 µm. Further, the thickness of one piece of the above metal powder is preferably less than or equal to 50nm. The silver paper is used as a substrate, on which design printing for decoration is implemented in a manner of offset printing. Next, various decorations are implemented through foil pressing or screen printing. Then, a paper lamination machine is used to laminate the paper. Demoulding and other processings are then implemented so as to make the metal decorative product in the embodiments of the present disclosure. Also, in the process of the above-described coating of silver ink, one time brushing and two times brushing (overlapping brushing) are attempted.

[0030] Next, as a comparison example, a silver paper making use of the existing laminations is utilized to make aluminum foil product which serves as the metal decorative product.

[0031] Then, the metal decorative product in the embodiments of the present disclosure is compared with the aluminum foil product in the above comparative example. In a state that the metal decorative product is containing RFID tags in UFH band, the communication performance of the RFID is acknowledged. As a result, the RFID in the existing aluminum foil product as comparative example cannot perform communication. On the other hand, the communication performance of the RFID in the metal decorative product as recited in the embodiments of the present disclosure does not deteriorate, and can perform communication. Also, the results remain the same, either with one time brushing or two times brushing.

[0032] Further, the metal decorative product in the embodiments of the present disclosure is compared with the aluminum foil product in the above comparative example with respect to the metallic luster of appearance. The result is that both of them have the same metallic luster.

[0033] Next, the second embodiment of the present disclosure is illustrated with reference to Figure 4.

[Second Embodiment]



[0034] Figure 4 is a schematic diagram for illustrating the structure of the metal decorative product involved in the second embodiment. Similarly as described in Figure 3, the metal decorative product 10 is consisting of a substrate 11 such as paper. A metallic luster decoration coated packaging 31 is formed on the surface of the substrate 11. A printing layer is formed on the metallic luster decoration coated packaging 31. Electromagnetic wave device 21' such as RFID tag and the like are adhered to the surface of the metallic luster decoration coated packaging 31, with the printing layer intervening.

[0035] In addition, the status of the ink forming the metallic luster decoration coated packaging 31 is the same as that described in the first embodiment, thus is omitted herein.

[0036] When an RFID tag is attached to the surface of metal foil of a box, which is an existing metal decorative product, the electromagnetic wave generated by the RFID tag will cause eddy currents in the metal foil so that the electromagnetic wave device cannot perform communication.

[0037] On the other hand, in the metallic luster decoration coated packaging 31 of the metal decorative product 10 involved in the second embodiment, the metallic luster decoration coated packaging 31 is formed by coating an ink which is mixed with metal powder 1 and metal powder connection 3 formed by the metal powder 1. With ink 2, the metal powder 1 and the metal powder connection formed by the metal powder 1 are insulated and independent from each other so as to inhibit the generation of eddy currents in the metallic luster decoration coated packaging 31. Thus, as shown by the arrow in Figure 4, even if the electromagnetic wave device 21' such as RFID tags are attached to the surface of the metallic luster decoration coated packaging 31, the electromagnetic wave generated by the electromagnetic wave device 21' can still be radiated out so that the electromagnetic wave device 21' can perform communication.

[0038] Although the first and second embodiments of the present disclosure are described above, various omissions, replacements and modifications can be made without departing from the scope of the idea of the present disclosure.

[0039] Further, in the first and second embodiments, while a wine bottle packaging, which is a box shaped product, is exemplified as an example of the metal decorative product of the present disclosure, the present disclosure is not limited to this but can also be applied to bag shaped products and laminated products. For example, as an example of the laminated product, there is "IC card" or "IC ticket", wherein a component namely RFID insert is laminated at both front side and back side using a sheet shaped substrate having a metallic luster decoration coated packaging.

[0040] Besides, in the first and second embodiments, printing methods such as stereoscopic printing, dot printing, etc. can be enumerated as a method of forming the metallic luster decoration coated packaging 31 on the surface of the substrate 11.

[0041] Besides, apart from "coated paper", "resin film" (such as PET, PVC, PE, PP, etc.) and "wood" can also be used as the substrate of the metal decorative product.

[0042] As an example of the structure that the metallic luster decoration coated packaging is formed on a substrate, for example, the metallic luster decoration coated packaging is formed in a manner of film coating on at least one side of a resin film which an extented polyethylene terephthalate (PET) resin film, an extended polypropylene (PP) resin film, an acrylic acid resin film, a cellulosic resin film, a vinyl chloride resin film, or other transparent film.

[0043] Further, the resin film which is an extented polyethylene terephthalate (PET) resin film, an extended polypropylene (PP) resin film, an acrylic acid resin film, a cellulosic resin film, a vinyl chloride resin film, or other transparent film can also be laminated with other substrates to form a composite substrate, and the metallic luster decoration coated packaging is formed in a manner of film coating on an outer surface of a film side of the laminated composite substrate, that is, on a surface of a side of the resin opposite to the side facing to said other substrate.

[0044] Further, the resin film which is an extented polyethylene terephthalate (PET) resin film, an extended polypropylene (PP) resin film, an acrylic acid resin film, a cellulosic resin film, a vinyl chloride resin film, or other transparent film can also be laminated with paper substrates to form a composite substrate, and the metallic luster decoration coated packaging is formed in a manner of film coating on an inner surface of a film side of the laminated composite substrate, that is, on a surface of a side of the resin facing to the paper substrate.

[0045] Further, in the first and second embodiments, the surface resistivity (surface resistance) of the coating is preferably greater than or equal to 100 Ω/sq in order to ensure the transmittance of the radio wave.

[0046] Further, Figures 1 and 4 show the situation where the metallic luster decoration coated packaging 31 is formed on the entire surface of the substrate 11, but it is not limited to this. The metallic luster decoration coated packaging 31 can also be formed on a portion of the surface of the substrate 11. Also, the metallic luster decoration coated packaging 31 can also be formed on the back of the substrate 11, or on both front side and back side of the substrate 11.
