Description

Scratch gift certificate having improved security and concealment}

The present invention relates to a scratch gift certificate, and more particularly, to a scratch gift certificate with improved concealability and security.

Gift certificates are bearer bonds with a fixed amount that can be exchanged for products, such as cultural gift certificates and department store gift certificates. Gift certificates are provided in the form of printed paper with the amount, number (fin number) and barcode. When a user directly uses a gift certificate offline, there is little possibility of a problem arising from exposure of the gift certificate number. However, in the case of gift certificates that are frequently used online (eg, cultural gift certificates, game gift certificates, etc.), they are provided in the form of scratch gift certificates with concealment means applied to prevent unnecessary exposure of the gift certificate number in the distribution stage. In particular, in the case of a high-priced gift certificate such as a department store gift certificate, since special paper to which various security elements are applied is used, lithographic printing and intaglio printing are performed on a sheet-type paper instead of a roll-type paper, and the concealment means is applied.

Korean Patent Publication No. 2011-0135607 proposes a scratch foil applied to gift certificates and the like. After the scratch foil is printed to hide confidential information, winning information, or information such as text or pictures, such as gift certificates, coupons, or lottery tickets, scrape the hidden information with a coin or a fingernail to check it. However, even if the conventional scratch gift certificate is covered with a scratch foil, it is possible to read the gift certificate information by illuminating a light source such as a lantern with increased output and straightness. In addition, even if a scratch hologram with a hologram is used, it is unavoidable to read the voucher information by the strong light of the light source. A conventional scratch gift certificate may have perforations, and gift certificate information can be read by applying a small amount of work to the perforations. When the gift certificate information is read, the function of the gift certificate disappears.

The problem to be solved by the present invention is to provide a scratch gift certificate with improved concealment security so that gift certificate information is not read through strong light and perforation.

A scratch gift certificate with improved concealment security for solving the problems of the present invention includes an information confirmation unit disposed on the paper. In the information confirmation unit, a scratch layer, a protective layer, an information layer and a hiding layer are sequentially stacked, and the hiding layer is made of a white polymer film to which white inorganic particles are added.

In the gift certificate of the present invention, the protective layer may be any one selected from a deposition layer by deposition or a metal foil or a polymer film by stamping. The hiding layer may include fine pores. The hiding layer may include a coated color layer or a pigment or dye or a combination thereof to express color. The hiding layer may include a reflective layer that reflects the incident light incident from the paper direction.

In a preferred gift certificate of the present invention, the concealing layer may include a concealing pattern, a reflective pattern and an adhesive pattern. The reflective pattern may be disposed perpendicular to the paper to reflect the incident light incident from the paper direction at a reflection angle. The hiding layer may include an uneven reflective layer formed on the uneven layer.

According to the scratch gift certificate with improved concealment security of the present invention, by applying a concealing layer between the information layer and the paper, information such as a gift certificate number is not read through strong light and perforation. In addition, by including a reflective layer or a reflective pattern or a concave-convex reflective layer in the concealment layer, information is blocked from being read by means such as strong light.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments described below may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described in detail below. The embodiments of the present invention are provided to more completely explain the present invention to those of ordinary skill in the art. Meanwhile, in the drawings, thicknesses of films (layers, patterns) and regions may be exaggerated for clarity. Further, when it is said that a film (layer, pattern) is on, on, on, under, or on one side of another film (layer, pattern), it may be formed directly on the other film (layer, pattern) or other films (layers, patterns) may be formed between them. A film (layer, pattern) may be interposed.

An embodiment of the present invention proposes a scratch gift certificate with improved concealment security so that information such as a gift certificate number is not read through strong light and perforation by applying a hiding layer between the information layer and the paper. To this end, a detailed description will be given of a scratch gift certificate including a concealing layer, and a process of preventing information such as a gift certificate number from being read by the concealing layer. Here, the concealment security refers to preventing information such as a gift certificate number from being read by means such as strong light. The gift certificate according to an embodiment of the present invention is preferably applied to a high-priced gift certificate such as a department store gift certificate, and the gift certificate may be extended to a coupon, a lottery ticket, or the like.

1 is a plan view showing a scratch gift certificate 100 according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line II-II of FIG. However, the drawings are not expressed in a strict sense, and there may be components not shown in the drawings for convenience of description.

1 and 2 , the scratch gift certificate 100 includes an information confirmation unit 20 disposed in a predetermined area of the paper 10 . The location of the information confirmation unit 20 is set in advance according to the type and size of the gift certificate 100 . The paper 10 is not particularly limited, and may be made of a conventional material such as paper or a film made of synthetic resin material. The paper 10 uses special paper to which various security elements are applied, and lithographic printing and intaglio printing are performed on the sheet 10 in the form of a sheet.

The information confirmation unit 20 includes a scratch layer 21 , a protective layer 22 , an information layer 23 , and a first hiding layer 30 , and is disposed on the paper 10 . The scratch layer 21 prevents the information layer 23 from being exposed, and when a user scratches with a coin or fingernail, the information contained in the information layer 23 can be checked. The scratch layer 21 includes a hologram, so that the authenticity of the gift certificate can be checked only by the hologram itself, and the security can be further improved so that the information of the information layer 23 is not exposed. That is, the hologram of the scratch layer 21 hides the information of the information layer 23 and prevents the information from being read through light transmission. Since the scratch layer 21 does not have a perforation unlike in the prior art, it fundamentally blocks the reading of the information made by applying an operation to the perforation with a sharp needle.

The scratch layer 21 may form a pattern and a hologram by a hot stamping method according to the purpose and type of the gift certificate. The high-temperature stamping method is to print by attaching metal foils such as gold foil, silver foil, aluminum foil, and ink foil at high temperature and high pressure. In particular, the ink leaf makes the pattern of the scratch layer 21 and the image of the hologram look luxurious. Since it is already known to apply various patterns and holograms to the scratch layer 21, a detailed description thereof will be omitted.

The protective layer 22 has a degree of transparency that allows information of the information layer 23 to be confirmed. The protective layer 22 protects the gift certificate information by enabling the scratch layer 21 to be easily peeled off when the surface of the paper 10 is not smooth and preventing the gift certificate information from being damaged by contamination. The protective layer 22 can be formed in various ways, but is preferably formed by a deposition method such as an electron beam or a high-temperature stamping method. The protective layer 22 by the deposition method is a deposition layer in which a metal such as aluminum or copper is deposited to a thin thickness to the extent that transmittance is secured. The protective layer 22 by the high-temperature stamping method can attach a metal foil such as aluminum, copper, etc. at high temperature and high pressure to the extent that transmittance is ensured.

In some cases, the protective layer 22 may be formed by bonding a transparent polymer film. The transparent polymer film is made of a thermoplastic resin, preferably PET (PolyEthylene Terephthalate), PEN (PolyEthylene Naphthalate), PES (PolyEther Sulfone), PI (PolyImide), PAR (PolyARylate), PC (PolyCarbonate), PMMA (PolyMethyl MethAcrylate) ), PU (PolyUrethane), TAC (Tri-Acrtyl-Cellulose), or COC (CycloOlefin Copolymer) may be at least one selected from. The polymer film is attached to the information layer 23 with an adhesive such as an optically clear adhesive (OCA), and the adhesive is an acrylic resin, silicone resin or urethane resin, thermosetting resin, or UV curable resin mixed with a crosslinking agent, or a mixture thereof. Or it may be any one selected from their copolymers.

The information layer 23 contains exchange information for confirming a predetermined amount to be exchanged for a product. The exchange information consists of numbers, letters, patterns, or a combination thereof, and in the case of a pattern, it may be in the form of an animal or a plant replacing the exchange information. The exchange information may be expressed in various colors as well as black, and saturation and transparency may be variously adjusted.

The first hiding layer 30 is basically made of a white polymer film. It is made by adding a large amount of white inorganic particles to a polymer film. The first hiding layer 30 is prepared by adding white inorganic particles having a size of about 0.01 to 15 μm to the resin constituting the base film. The size of the white inorganic particles is to control optical properties such as light transmittance and color, and surface properties of friction coefficient and surface roughness. When the size of the white inorganic particles is smaller than 0.01 μm, the effect of improving optical properties and surface properties is insignificant, and when it exceeds 15 μm, the surface roughness of the film becomes excessively large, giving a rough feeling. The white inorganic particles may be any one selected from the group consisting of barium sulfate, titanium, a titanium compound, silicon dioxide, calcium carbonate, magnesium oxide and talc, or a mixture of at least one selected from the group.

The base film may be made of a polyester-based resin alone, a copolymer of a polyester-based resin and a polyolefin resin, or a polypropylene resin. In particular, when a polyolefin resin is copolymerized with a polyester resin, the texture of the white polymer film can be preserved and its own density can be reduced. When copolymerization is performed, fine pores are formed on the surface and inside of the film due to poor compatibility between resins. In addition, when a polyester-based resin or a polypropylene-based resin is used, fine pores can be generated in the film due to the difference in the elongation ratio between the white inorganic particles and the resin during the stretching process. Therefore, the fine pores can be formed by two methods, either due to poor compatibility between the resins or by the difference in elongation between the white inorganic particles and the resin.

When the fine pores are formed in the base film, the information layer 23 may be directly printed on the first hiding layer 30 . The fine pores allow the information of the information layer 23 to be easily printed. In other words, the first hiding layer 30 according to the embodiment of the present invention may be put into the manufacture of the gift certificate 100 in a state in which the information of the information layer 23 is printed.

The first hiding layer 30 may have a color. Specifically, the color may be coated with a separate color layer on the white polymer film, or a pigment, dye, or the like expressing color may be added to the white polymer film. The color of the first hiding layer 30 may be variously set in consideration of the color of the information of the information layer 23 . For example, the colors of the information of the first hiding layer 30 and the information layer 23 may form a complementary color relationship. In addition, the first hiding layer 30 may be mixed with a special ink, such as a UV discoloration ink or colorless fluorescent ink, in order to enhance security. In the case of coating, a gravure coater or a reverse coater was used depending on the application amount, and the application amount is preferably 5-12 g/m2 in consideration of color and hiding properties.

If necessary, although not shown, a reflective layer may be formed on the first hiding layer 30 . The reflective layer is formed by physical vapor deposition or chemical vapor deposition, preferably physical vapor deposition. The physical vapor deposition may use various methods such as an electron-beam, an ion-beam, sputtering, and a method using an excimer laser. The material of the reflective layer is preferably a metal, and the metal is at least one layer selected from the group consisting of Al, Ag, Cu, Au, Pt, Pd, Rh, Ni, W, Mo, Cr, Sn, Ti, or their It may be a composite layer. Suitably, either Ag or Al or an Ag-Al alloy is preferred. When the information confirmation unit 20 is irradiated with a strong light or the like, the incident light is reflected by the reflective layer to block the reading of information on the information layer 23 .

3 is a perspective view for explaining the second hiding layer 40 applied to the scratch gift certificate 100 according to the embodiment of the present invention. At this time, except for the second hiding layer 40, the scratch gift certificate 100 is the same as described above.

Referring to FIG. 3 , the second hiding layer 40 includes a concealing pattern 41 , a reflective pattern 42 , and an adhesive pattern 43 . The concealing pattern 41 has the same material as that of the first concealing layer 30 except for the pattern state of the first concealing layer 30 described above. The reflective pattern 42 is formed by physical vapor deposition or chemical vapor deposition, preferably physical vapor deposition. The physical vapor deposition may use various methods such as an electron-beam, an ion-beam, sputtering, and a method using an excimer laser. The material of the reflective pattern 42 is preferably a metal, and the metal is at least one selected from the group consisting of Al, Ag, Cu, Au, Pt, Pd, Rh, Ni, W, Mo, Cr, Sn, and Ti. layer or a composite layer thereof. Suitably, either Ag or Al or an Ag-Al alloy is preferred.

The reflective pattern 42 is disposed perpendicular to the paper 10 , and reflects incident light incident from the paper 10 direction at various angles. If a strong light is irradiated from the direction of the paper 10 to the direction of the information confirmation unit 20 , the incident light transmitted through the paper 10 is varied by the reflection pattern 42 before reaching the information layer 23 . reflected at the angle of reflection. The reflected light reflected by the reflective pattern 42 blurs the image of the information layer 23 so that the information cannot be read.

The adhesive pattern 43 is made of an adhesive, and may be formed by coating any one of an acrylic resin, a silicone resin, an epoxy resin, a urethane resin, or a composite resin thereof. Meanwhile, the adhesive pattern 12 of the present invention is preferably made of a heat seal material. Since the heat-adhesive material is adhered by heat and pressure, it is advantageous for manufacturing the second hiding layer 40 . The heat-adhesive material is, for example, a polyethylene/polypropylene copolymer having excellent adhesion to metal, random polypropylene, maleic acid graft polypropylene, maleic acid graft polypropylene/polyethylene copolymer, acrylic acid polyethylene/polypropylene copolymer, There are ionomer resins or carboxylated resins, ethylene vinyl acetate, polyvinyl butyral, and the like.

4 is a cross-sectional view for explaining the third hiding layer 50 applied to the scratch gift certificate 100 according to the embodiment of the present invention. At this time, except for the third hiding layer 50, the scratch gift certificate 100 is the same as described above.

Referring to FIG. 4 , the third hiding layer 50 includes an uneven layer 51 and an uneven reflective layer 52 . The material of the concave-convex layer 51 is the same as that of the first hiding layer 30 , except that the concavo-convex layer 51 is formed with concavities and convexities. The unevenness is a general term for imparting roughness to the surface by not being flat but having a curve. The curvature is angled, curvature, or a combination thereof. For example, the unevenness of the concave-convex layer 51 may be in the form of a band having a certain width, or a polygonal pyramid such as a cylinder, a hemisphere, or a triangular pyramid, a polygonal truncated pyramid such as a triangular truncated pyramid, and a combination of the above shapes. In other words, the unevenness of the uneven layer 51 may be variously modified within the scope of the present invention.

The uneven reflective layer 52 is formed by physical vapor deposition or chemical vapor deposition, preferably physical vapor deposition. The physical vapor deposition may use various methods such as an electron-beam, an ion-beam, sputtering, and a method using an excimer laser. A metal is preferable, and the metal may be at least one layer selected from the group consisting of Al, Ag, Cu, Au, Pt, Pd, Rh, Ni, W, Mo, Cr, Sn, Ti, or a composite layer thereof. Suitably, either Ag or Al or an Ag-Al alloy is preferred. When the information confirmation unit 20 is irradiated with a strong light or the like, the incident light is reflected by the concave-convex reflective layer 52 to block the reading of information on the information layer 23 .
