Description

[DESCRIPTION]

[Invention Title]

STICKER HAVING GENUINE PRODUCT IDENTIFICATION FUNCTION AND

METHOD OF MANUFACTURING THE SAME

[Technical Field]

The present invention relates to a sticker provided with a genuine product

identification function and a method of manufacturing the same, whereby the sticker

includes a hologram of a pattern or design for genuine product identification and forgery

prevention and the sticker connot be reused once it is peeled off from a product.

[Background Art]

With the development of diverse copying technologies, company logos or designs as

well as products have been forged increasingly, and forgeries have been sold fraudulently.

Since only a distributor has all information on the marketing channel of a product and a

consumer cannot directly check up the manufacturing process of the product, it is not easy

for the consumer to check whether the product is genuine. In particular, counterfeits of

expensive goods, foreign imports, exports, or counterfeit brands have been produced and

illegally distributed. If a consumer misconceives and purchases a counterfeit having an

inferior quality as a genuine one, it causes financial and mental losses to the

consumer. Since it is not easy to keep control over illegal counterfeits, the resultant disadvantages are directly shifted to the consumers. Further, due to the distribution and

selling of the illegal counterfeits, genuine manufacturers are at pains to pick up the illegal

counterfeits, and the reliability of the manufacturers' brands may deteriorate with financial

losses.

A method for identifying a genuine article is disclosed in International Publication

No. WO 2003/053708. A safety label disclosed in the publication includes one recording

medium, and on the surface of the recording medium, there are arranged an overt area

formed by an overt technology and a covert area formed by a covert technology. The

safety label can be adhered onto a target object, such as a product or a package thereof, by

an adhesive layer. Since the overt area is visually identified, the overt area may be

forged. The covert area is not visually identified, but can be identified through a separate

identifying device such as black light. Therefore, there is a problem that it is difficult to

discriminate the genuineness.

An example of employing a forgery-free hologram is disclosed in Korean Patent

Unexamined Publication No. 2003-0021483 which relates to a forgery-free label and a

method of manufacturing the same. The hologram is made by preparing a master film of

hologram and transferring recesses of the master film onto a hologram film using heat and

pressure. The hologram is attached onto products or goods in the form of a sticker or label

to show an excellent function of restraining the manufacture and/or distribution of the counterfeits. However, since the hologram is distinguishable with the naked eye, the

hologram can be almost similarly forged. A common consumer can hardly distinguish the

counterfeit having the forged hologram from the genuine.

[Disclosure]

[Technical Problem]

Accordingly, the present invention has been made to solve the above-mentioned

problems occurring in the prior art, and an object of the present invention is to provide a

sticker provided with a genuine product identification function and a method of

manufacturing the same, whereby information printed in the sticker does not appear on the

surface of the sticker and cannot be identified with the naked eye, so that the sticker can be

prevented from being forged, and a consumer can easily identify whether the product is

genuine from the printed information when he/she directly peels off the sticker from the

product.

Another object of the present invention is to provide a sticker provided with a

genuine product identification function and a method of manufacturing the same, whereby

the sticker cannot be reassembled and reused once it is peeled off, thereby preventing the

illegal copying of it.

Additional advantages, objects, and features of the invention will be set forth in part

in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the

invention.

[Technical Solution]

In order to accomplish these objects, there is provided a method of manufacturing a

sticker provided with a genuine product identification function, according to the present

invention, which includes the steps of printing a pattern or design for genuine product

identification on a resin-based film which is made of at least one selected from a group

consisting of a polyester film, an oriented polypropylene (OPP) film, and a cast

polypropylene (CPP) film, a paper, and a synthetic paper; forming a thin resin layer on the

resin-based film printed with the pattern or design by coating a plastic resin mixed with a

pigment on the resin-based film; forming a hologram layer on the resin layer; forming a

metal deposited layer on the hologram layer; and forming an adhesive layer on the metal

deposited layer.

In the method of manufacturing the sticker provided with the genuine product

identification function, the step of forming the hologram layer and the step of forming the

metal deposited layer may be performed in a reverse order.

In the method of manufacturing the sticker provided with the genuine product

identification function, the plastic resin used to form the resin layer is made of at least one

selected from a group consisting of thermoplastic polyurethane resin, polyurethane, polyvinylchloride (PVC), vinylacetate copolymer, polyamide, polycarbonate, cellulose

ester, fluoride resin, polyacetal resin, and polyimide resin.

The method of manufacturing the sticker provided with the genuine product

identification function may further include the step of forming a resin layer on the resin-

based film before printing the pattern or design for the genuine product identification on the

resin-based film.

The step of printing the pattern or design for the genuine product identification may

be performed using a resin made of at least one selected from a group consisting of wax,

silicon wax, silicon, silicon resin, and fluorocarbon resin.

According another aspect of the present invention, there is provided a sticker

provided with a genuine product identification function, including a resin-based film on

which a pattern or design for genuine product identification is printed, the resin-based film

being made of at least one selected from a group consisting of a polyester film, an oriented

polypropylene (OPP) film, and a cast polypropylene (CPP) film, a paper, and a synthetic

paper; a thin resin layer formed on the resin-based film printed with the pattern or design by

coating a plastic resin mixed with a pigment on the resin-based film; a hologram layer

formed on the resin layer; a metal deposited layer formed on the hologram layer; and an

adhesive layer formed on the metal deposited layer. [Advantageous Effects]

According to the sticker provided with the genuine product identification function

as constructed above, information recorded on the rear surface of the sticker is not exposed

to an outside, and thus the sticker is prevented from being forged. When a consumer or

purchaser directly peels off the sticker from the product, a part of the sticker is detached

from the product, and the remaining part of the sticker on the surface of the product shows

the hologram of the pattern or design for the genuine product identification.

Once the sticker is peeled off, the hologram layer and the metal deposition layer are

broken and thus the sticker cannot be reassembled to prevent the forging of the sticker.

[Best Mode]

Hereinafter, preferred embodiments of the present invention will be described in

detail with reference to the accompanying drawings.

FIG. 1 is a perspective view illustrating a product B to which a sticker A having a

genuine product identification function according to the present invention is adhered. FIG.

2 is a perspective view explaining a genuine product identification function of a sticker

according to the present invention.

If a consumer or purchaser peels off a film 60 of the sticker from the product B, a

hologram of a specified pattern or design 50, which is used by a manufacture for the

genuine product identification, appears from the surface of the product B. Thus, the consumer or purchaser can identify the product as a genuine product, thereby providing the

effects of genuine product identification and forgery prevention.

A resin layer is coated on the outer surface of the sticker A, and information or

design to be transferred to the consumer or purchaser is printed on the resin layer, so that

the consumer or purchaser can primarily identify the information printed on the sticker

A. If the consumer or purchaser peels off the film 60 of the sticker A from the product B,

the hologram of the specified pattern or design 50 appears on the surface of the product B.

FIGs. 3 and 4 are views explaining the process of manufacturing a sticker according

to embodiments of the present invention.

In FIG. 3, the resin-based film 60 is the uppermost layer of the sticker A, and

through the resin-based film, the consumer or purchaser can see the information or design

to be transferred to the consumer. The resin-based film may be at least one selected from a

group consisting of a polyester film, such as a polyesthylene terephthalate film or

polybutylene terephthalate, a polyamide film, a polyacrylate film, a polycarbonate film, a

cellulose ester film, an ester film, a fluoride resin-based film, a polyacetal film, and a

polyimide film, and preferably, it may be the polyester film, oriented polypropylene film

(OPP), or a cast polypropylene film (CPP). A paper or synthetic paper may also be

applicable thereto. The resin-based film 60 is printed with the pattern or design 50 for identifying the

genuine product, and is made of at least one selected from a group consisting of wax,

silicon wax, silicon, silicon resin, and fluorocarbon resin, preferably, silicone, and silicone

resin. The silicon resin is a polymer resulted from condensation reacting organosilicon

intermediate, in which silicon has a good heat resistance and water repellency, and has

superior characteristics to those of an organic substance in electric insulation, chemical

resistance, anti-aging, and non-volatility.

The printed pattern or design is dried by hot blast of 100 to 150^°C . The pattern or

design for identifying the genuine product according to the present invention is printed by a

screen printing method or a gravure printing method.

A resin layer 40 is formed on the pattern or design 50 for identifying the genuine

product, and is made of plastic resin, which serves as a support layer for forming a

hologram layer 30. The plastic resin layer is made of at least one selected from a group

consisting of polyamide, polycarbonate, cellulose ester, fluoride resin, polyacetal, and

polyimide resin, and preferably, it is made of one selected from a group consisting of

thermoplastic polyurethane resin, polyurethane, polyvinylchloride (PVC), and vinylacetate

copolymer. When the resin layer 40 is formed, the material of the resin layer may be

mixed with pigment so that the resin layer shows various colors. After the plastic resin is mixed with the pigment, it is coated on the resin-based film as a thin film, and then is dried

by hot blast of 100 to 150⁰C .

The hologram layer 30 is formed on the resin layer 40, and then a metal deposition

layer 20 is formed on the hologram layer 30. The hologram layer 30 and the metal

deposition layer 20 may be formed in a reverse order.

The metal deposition layer 20 provides an effect of reflecting light, in which a

reflective metal substance such as aluminum is deposited in vacuum.

In the case where the metal deposition layer 20 is formed on the resin layer 40 and

then the hologram layer 30 is formed on the metal deposition layer 20, the hologram

appears clearly and colorfully by the reflection of light from the metal.

Then, the metal deposition layer 20 is coated with an adhesive layer 10, and a

release paper C is attached onto the adhesive layer. If the release paper C is peeled off, the

sticker is adhered to the product B by the adhesive layer. The adhesive layer 10 may be

coated by a hot-melt adhesive, as well as a acrylic-based adhesive and a rubber-based

adhesive. The hot-melt adhesive is a nonpolluting thermovision adhesive which is

composed of thermoplastic resin as a base polymer, without using water or solvent, which

is made by mixing a tackifier, an antioxidant, and a filler with a main component of wax for

reducing viscosity at fusion, and which is applied on the surface of an adherent and then is

solidified to provide an adhesive force. Specifically, after the hot-melt adhesive is applied by melting solid thermoplastic resin of 100% only, without dissolving or dispersing a solid

state material with a solvent at room temperature, applying the molted thermoplastic resin,

and heating the adherent or the circumstance around the adherent to solidify the adhesive

for a short time. As compared with other solvent adhesives or aqueous dispersion-type

adhesive, a drying process is not required, and thus a working space is reduced with an

increased adhering speed.

The release paper C is attached onto the adhesive layer 10. Although the release

paper C is positioned under the sticker A, it is detached from the sticker A when the sticker

is adhered onto the product B (see FIG. 5).

Referring to FIG. 4, the resin layer 40 is formed on the resin-based film 60, the

pattern or design 50 for identifying the genuine product is printed on the resin layer, and the

resin layer 40 is formed on the pattern or design 50. Logo characters can be stably formed

according to the attaching method.

layer 20 is formed on the hologram layer 30. As shown in FIG. 3, prior to the forming of

the hologram layer 30, the metal deposition layer 20 may be formed on the resin layer 40.

Then, the metal deposition layer 20 is coated with the adhesive layer 10, and the

sticker is adhered to the product B by the adhesive layer. FIGs. 5 and 6 are cross-sectional views illustrating the structure of the sticker

according to the present invention.

More specifically, the sticker A shown in FIG. 5 includes the adhesive layer 10,

metal deposition layer 20, hologram layer 30, resin layer 40, pattern or design 50, and

resin-based film 60, thereby providing the sticker with the genuine product identification

function. In this case, the hologram layer 30 and the metal deposition layer 20 may be

formed in a reverse order.

The sticker A shown in FIG. 6 includes the adhesive layer 10, metal deposition layer

20, hologram layer 30, resin layer 40, pattern or design 50, resin layer 40, and resin-based

film 60. The resin layer 40 is added between the resin-based film 60 and the pattern or

design 50, thereby providing the sticker with the genuine product identification

formed in a reverse order.

When the sticker A provided with the genuine product identification function is

applied to the product B, the sticker is adhered onto the production in such a way that the

resin-based film 60 faces upward (see FIG. 7).

Therefore, the manufacturing sequence is identical to that as illustrated in FIGs. 3

and 4, and the construction of the completed sticker A is identical to that as illustrated in

FIGs. 5 and 6. FIG. 7 is a cross-sectional view explaing a genuine product identification function of

a sticker according to the present invention. In order to adhere the sticker A onto the

product B, the release C is firstly peeled off from the adhesive layer 10, and the adhesive

layer 10 is positioned and adhered onto the wanted part of the genuine product B. Since

the pattern or design layered and printed in the sticker does not appear on the surface of the

sticker, the content cannot be identified with the naked eye. Accordingly, the sticker can

be prevented from being forged.

When the consumer or purchaser who has purchased the genuine product intends to

identify whether the product is genuine, he/she directly peels off the sticker A provided

with the genuine product identification function from the product B. At this time, as the

resin-based film 60 is detached from the sticker, and the pattern or design 50 appears in a

hologram fashion to identify the genuine product. That is, the sticker A is broken

according to the uneven adhesive of the adhesive layer 10. Specifically, a part of the

sticker is detached from the product together with the resin-based film 60, and the

remaining part of the sticker on the surface of the product shows the hologram of the

pattern or design 50 for the genuine product identification, thereby identifying whether the

product B is genuine.

Once the sticker A is peeled off, the hologram layer and the metal deposition layer

are partially ruptured, and thus it is impossible to reuse the sticker. Consequently, the sticker is prevented from being forged or reused by other persons, and the consumer can

easily identify the genuine product.

[Industrial Applicability]

In case of applying the sticker of the present invention to the products generally

purchased, the consumers can easily identify whether the product is genuine with the naked

eye, and the manufacturers can prevent the forgery of their products. The sticker provided

with the genuine product identification function according to the present invention may be

applied to diverse printed matters, such as mail matters, bank notes, securities, and identity

cards.

Although preferred embodiments of the present invention have been described for

illustrative purposes, those skilled in the art will appreciate that various modifications,

additions and substitutions are possible, without departing from the scope and spirit of the

invention as disclosed in the accompanying claims.
