Description
Metal card having a three-dimensional glass effect and method for manufacturing the same
[0001] The present invention relates to a metal card and a method for manufacturing the same, and more particularly, to a metal card and a method for manufacturing the same, which are configured to form a design and pattern on a sheet of synthetic resin material, perform mirror deposition to implement a front mirror body that provides excellent reflectivity and three-dimensionality, and to laminate the front mirror body to a rear metal body, thereby enhancing the three-dimensionality of the pattern and design formed on the surface of the card and creating a three-dimensional glass effect that further enhances the luxuriousness of the metal card.
[0002] Credit cards are used for identification, payment, and credit extension. Because most users carry them with them at all times, their shapes and designs are becoming more elaborate, imbuing them with artistic value and the functionality of accessories. Furthermore, the shape and design of credit cards, along with their services, discounts, and reward points, are crucial factors in selecting a credit card. Accordingly, card manufacturers are striving to meet the diverse needs of customers by developing cards that differ significantly in shape, design, and functionality.
[0003] As one of these efforts, various attempts have been made to create a more splendid card design by adding a three-dimensional pattern to the surface of the credit card to provide a three-dimensional effect.
[0004] Korean Patent Publication No. 10-2012-0120520, a patent application filed by the applicant and published by the present invention, discloses a “method for manufacturing a special pattern card,” and proposes a technique for manufacturing a special pattern sheet having a three-dimensional pattern corresponding to a special pattern using a pattern mold having a three-dimensional pattern formed thereon, and laminating sheets including the special pattern sheet and then thermally compressing them to form a bond. The technique is characterized by enabling the formation of a detailed pattern on a card using the special pattern sheet. However, when the special pattern sheet of the technique is manufactured on a PVC sheet, the PVC sheet has low transmittance, which causes a problem in that the three-dimensional effect of the three-dimensional pattern of the special pattern sheet is reduced.
[0005] Meanwhile, with the trend toward increasingly flashy shapes and designs, credit cards, previously primarily made of plastic, are increasingly diversifying in materials to meet consumer tastes and demands. One such material is metal cards. Metal cards offer a distinctive metallic sheen and a comfortable weight, along with a distinctive texture, enhancing the user experience and solidifying their position as high-quality credit cards.
[0006] Meanwhile, the applicant of the present invention has proposed a "metal card with a glass body" in Korean Patent No. 10-2561968. The patent implements a new type of metal card that can enhance the three-dimensionality of the pattern and increase the sense of luxury by mounting a front glass body made of a glass material sheet on the card surface. However, the metal card according to the patent has a problem in that it is easily broken by external forces such as impact or bending due to the nature of the glass contained in the front glass body. In addition, if the glass body made of glass material breaks or is damaged, there is a problem that accidents such as injury to the cardholder may occur due to glass fragments.
[0007] Accordingly, the present invention proposes a method for improving the three-dimensionality of a pattern, like a conventional metal card with a glass body, while preventing the glass from being broken by an external force or an accident caused by the glass being broken.
[0008] In order to solve the above-mentioned problems, the present invention provides a metal card and a method for manufacturing the same, which can enhance the three-dimensional effect of the pattern without worrying about glass breakage or accidents caused by forming a design and pattern on the surface of a sheet of synthetic resin material and depositing a mirror to produce a front mirror body capable of providing a glass effect with excellent reflectivity and three-dimensionality, and by laminating the front mirror body on the surface of a rear metal body, thereby creating a glass effect on the surface of the card.

[0032] Hereinafter, a metal card having a glass effect and a method for manufacturing the same according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.
[0033] FIG. 1 is a perspective view and a cross-sectional view taken along the line AA of an embodiment of a metal card having a glass effect according to a preferred embodiment of the present invention. Referring to FIG. 1, the metal card (1) according to the present invention includes a front mirror body (10), a rear metal body (20), and a first adhesive layer (30) disposed between the front mirror body and the rear metal body. The front mirror body (10) is a module in which a design and a pattern are formed on a sheet of synthetic resin material and a mirror is deposited, and is characterized in that it provides a glass effect having excellent reflectivity and a three-dimensional effect for the pattern. The rear metal body (20) is characterized in that it includes a metal sheet made of a metal material plate having a preset card size. The first adhesive layer (30) may be completed by applying an adhesive, formed by applying a UV-curable material and then curing it, or formed of an adhesive film such as a hot-melt film. By laminating a front mirror body to the upper surface of the rear metal body, a glass effect with excellent reflectivity is provided on the surface of the metal card, thereby enhancing the three-dimensionality of the pattern and design on the surface of the card and enhancing the luxuriousness of the metal card. Hereinafter, the configuration of the front mirror body and the rear metal body will be described in detail.
[0034] Fig. 4 is an exploded perspective view showing the structure of a front mirror body (10) during a manufacturing process in a metal card having a glass effect according to a preferred embodiment of the present invention. Referring to Fig. 4, the front mirror body (10) has a front printing layer (13), a pattern layer (14), and a mirror deposition layer (16) sequentially formed on the back surface of an upper substrate sheet (12), a second adhesive layer (17) formed on the surface of the mirror deposition layer, and a lower buffer sheet (19) mounted on the surface of the second adhesive layer.
[0035] The upper substrate sheet (12) is made of a sheet of transparent synthetic resin material, and has a glossy surface. The synthetic resin material constituting the upper substrate sheet may be made of one of polyvinyl chloride (PVC), polyethylene terephthalate (PET), polyethylene terephthalate glycol (PET-G), and polycarbonate (PC). Meanwhile, among the aforementioned synthetic resin materials, it is most preferable that PET, which has excellent transparency, be used for the upper substrate sheet. The front printing layer (13) is formed by printing a predetermined design or pattern on the back surface of the upper substrate sheet. The pattern layer (14) is formed by forming a predetermined pattern on the surface of the front printing layer. The patterns formed on the pattern layer include spin, lenticular, hologram, hairline, Fresnel, and stripe. The pattern layer further enhances the three-dimensional effect of the design or pattern of the front printing layer. The mirror deposition layer (15) is formed by depositing a predetermined metal material on the surface of the pattern layer. The mirror deposition layer provides a glass effect with excellent reflectivity for the pattern and design. The metal material constituting the above mirror deposition layer can further increase reflectivity by including aluminum (Al). Meanwhile, the metal material constituting the above mirror deposition layer may further include titanium (Ti), indium (Indium), etc. in addition to aluminum (Al).
[0036] The second adhesive layer (17) is a completed layer formed by applying a transparent UV-curable material to the surface of the mirror deposition layer and then curing it, and is formed between the mirror deposition layer and the lower buffer sheet (19) to bond them together.
[0037] The lower buffer sheet (19) is made of a sheet of synthetic resin material and is mounted on the surface of the second adhesive layer (17). The synthetic resin material constituting the lower buffer sheet may be made of one of polyvinyl chloride (PVC), polyethylene terephthalate (PET), polyethylene terephthalate glycol (PET-G), and polycarbonate (PC). Meanwhile, it is most preferable that the lower buffer sheet be made of PET, which has excellent transparency among the synthetic resin materials mentioned above. In addition, it is preferable that the lower buffer sheet be made of a glossy sheet with gloss. As described above, since the lower buffer sheet is made of a sheet having transparency and gloss properties, the reflective properties of the surface of the metal card can be further increased and the three-dimensional effect of the pattern can be further improved. In general, since the surface of a metal sheet is not smooth and has poor flatness, the reflective properties of the pattern placed on the upper part of the metal sheet are reduced. Accordingly, the metal card according to the present invention can improve the reflectivity of the pattern on the front by mounting the lower buffer sheet (19) constituting the front mirror body (10) on the surface of the metal sheet of the rear metal body (20) to improve the flatness of the surface of the metal sheet.
[0038] The rear metal body (20) constituting the metal card according to the present invention may be configured in various ways, including at least one or two or more metal sheets. Fig. 7 is an exploded perspective view illustrating one embodiment of the rear metal body during the manufacturing process in a metal card having a glass effect according to a preferred embodiment of the present invention. Referring to Fig. 7, the first embodiment of the rear metal body (20) is configured by sequentially stacking a metal sheet (21) made of a metal material plate having a preset card size, an EMI absorbing sheet (22), an antenna inlay sheet (23), a rear printing sheet (24), and a rear protection sheet (25), and third adhesive layers (27) having electrical insulation are arranged between the metal sheets, the EMI absorbing sheet, and the antenna inlay sheets. The third adhesive layer may be configured by applying an adhesive, or an adhesive film such as a hot-melt film that has the property of melting and adhering by heating and pressurization may be used.
[0039] The metal sheet (21) has a main body made of a metal sheet and has an insertion hole formed in a predetermined area of the main body. A chip module for a combination card that allows the metal card to communicate in both a contact and non-contact manner may be mounted in the insertion hole of the metal sheet, or a chip module for a contact card that allows contact communication may be mounted. Metal materials used as the metal sheet (21) may include steel, gold, silver, copper, titanium, duraluminium, aluminum, aluminum alloy, carbon, etc., including SUS.
[0040] The above EMI absorption sheet (22) may be composed of an electromagnetic wave absorption sheet having the property of absorbing electromagnetic waves or a ferrite sheet made of a ferromagnetic material having the property of shielding electromagnetic waves, and is placed between the metal sheet and the antenna inlay sheet. The electromagnetic wave absorption sheet is a sheet manufactured to a preset thickness by mixing powders of materials having the property of absorbing electromagnetic waves and a binder, and is composed of 1 to 10 wt%, 1 to 10 wt%, 70 to 90 wt%, and 5 to 15 wt% of silicon (Si), chromium (Cr), iron (Fe), and a binder, respectively, and the binder may be composed of a urethane series resin.
[0041] The above antenna inlay sheet (23) is a sheet whose main body is made of synthetic resin material and whose surface is patterned with antenna wiring that is connected to a card chip module. Both ends of the card chip module are electrically connected to both ends of the antenna wiring.
[0042] The above rear printing sheet (24) is a sheet made of a synthetic resin material, and is characterized by having a design, pattern, or design printed on its surface. The above rear protection sheet (25) is made of a transparent synthetic resin material, and is placed on the exposed surface of the rear printing sheet to protect the surface of the rear printing sheet. A magnetic strip may be attached to the back surface of the rear protection sheet.
[0043] Meanwhile, the second embodiment of the rear metal body (20) is configured by sequentially laminating a metal sheet, an antenna inlay sheet, a rear printing sheet, and a rear protection sheet, and an adhesive layer having electrical insulation is disposed between the metal sheet and the antenna inlay sheet. Unlike the first embodiment, the rear metal body according to the second embodiment does not have an EMI absorption sheet. In addition, the remaining components of the rear metal body according to the second embodiment, excluding the metal sheet, are the same as the corresponding components of the rear metal body of the first embodiment, except that the shape of the metal sheet is different from the corresponding components of the first embodiment. The metal sheet of the rear metal body according to the second embodiment is characterized in that it has an insertion hole for mounting a card chip module in a predetermined area of the main body, and has a slit formed by cutting between a corner of the main body of the metal sheet and a side surface of the insertion hole. The chip module for a card mounted in the insertion hole of the metal sheet of the rear metal body according to the second embodiment may be configured as a chip module for a combination card or a chip module for a contactless card, similar to the second embodiment.
[0044] Hereinafter, with reference to the attached drawings, a method for manufacturing a metal card having a glass effect according to a preferred embodiment of the present invention will be described in detail.
