Description

A pendant that changes color depending on temperature and a necklace including it {COLOR CHANGING PENDANT AND A NECKLACE COMPRISING THE SAME}

The following description relates to a pendant that changes color according to temperature and a necklace including the same.

In general, the pendant (pendant) refers to a decoration that enhances the appearance of the wearer by attaching to accessories such as necklaces, earrings, and bracelets. Since ancient times, people have worn various accessories such as necklaces and earrings with pendants on their bodies to express their beauty and differentiate themselves from others.

Pendants of various accessories to enhance the wearer's appearance are mainly manufactured by processing precious metals such as gold, platinum, and silver in various shapes. In addition, various jewelry such as diamonds, rubies, pearls, and amber are additionally added to add beauty.

On the other hand, although aesthetically excellent pendants are diverse, pendants that give special meaning to the wearer are limited. To give meaning to the accessory, special characters are engraved on the exterior of the pendant or various birthstones are inserted. However, since such a pendant is always in a state in which the writing or jewelry is exposed to the wearer, the fresh feeling or mysterious feeling decreases as time passes.

In addition, in the case of a conventional pendant, the color of the pendant is equally limited at every moment due to the nature of the material, and there is a limitation in giving a special meaning to the wearer. Therefore, there is a need for a pendant that can continuously give a special meaning to the wearer and can be produced in a variety of ways.

Hereinafter, with reference to the accompanying drawings, a description will be given of the necklace 1 that changes color according to the temperature according to the embodiment.

1 is a perspective view showing the front of the necklace 1 before the temperature change according to an embodiment.

In the present specification, the front side of the necklace 1 refers to the side that changes color according to the temperature as the front side. And, the opposite side is called the back side of the necklace (1).

Referring to FIG. 1 , the necklace 1 is configured to include a pendant 10 , a ring portion 11 and a chain 12 .

Here, the pendant 10 refers to a decoration that is attached to accessories such as necklaces, earrings, and bracelets to enhance the appearance of the wearer.

The front side of the pendant 10 changes color to transparent depending on the temperature it comes into contact with and a message appears. In addition, the back side of the pendant 10 is made of natural mother-of-pearl. The shape of the pendant 10 is not limited to a circular shape, as shown in FIG. 1 , and may have various shapes.

The ring part 11 is provided on one side of the rim part 103 formed to surround all the side surfaces of the pendant 10 on the outside of the pendant 10 .

The chain 12 is provided through the ring portion 11 so that the wearer can wear the pendant 10 on the neck.

Hereinafter, with reference to FIG. 2, the pendant 10 constituting the necklace 1 will be described in detail.

2 is a cross-sectional view showing a portion of the side of the pendant 10 constituting the necklace 1 according to an embodiment.

The pendant 10 is configured in a state in which the base part 100 , the message layer 101 , and the color change layer 102 are stacked.

The base part 100 is the back side of the pendant 10, and is made of natural mother-of-pearl. For example, the base part 100 may be a mother-of-pearl (mop shell), which is a kind of natural mother-of-pearl. However, the type of the base unit 100 is not limited to pearl shells, and conch shells or red shells may be used.

The message layer 101 includes an image or text, and is formed on one surface of the base unit 100 . At this time, the message layer 101 is made of an opaque material so that the base part 100 is not exposed at all. For example, the message layer 101 may be a white acrylic plate or a rubber plate. However, the material of the message layer 101 is not limited to the above-described example.

An image or text included in the message layer 101 may be printed with black ink. The printing method may include, for example, a message desired by the wearer in a silk printing method. In addition, the message can be engraved in the form of a colored engraving as well as printing. In this way, various methods are possible for the method of inserting the message. The color is also not limited to the above-mentioned black, and various colors in which the message can be seen are possible.

The image or text of the message layer 101 is not limited to a specific shape or text. All shapes and texts are possible only within the range that can be included in the area of the message layer 101 .

The color-changing layer 102 is formed on the message layer 101 , and becomes the front side of the pendant 10 .

The color-changing layer 102 includes a reversible Zion pigment so that the color changes according to the temperature with which it is contacted. As the Zion pigment, any known Zion pigment material may be used without limitation. For example, the Zion pigment has the form of microcapsules having a size of 1 to 10 μm in which a thermochromic material is encapsulated. In this case, the discoloration material of the Zion pigment may be black, and the discoloration temperature may be 30°C.

Here, with reference to FIGS. 1 and 3 , the necklace 1 that changes according to the temperature change of the color-changing layer 102 will be described in detail.

1 is a perspective view showing the front side of the necklace before the temperature change according to an embodiment, as described above, and FIG. 3 is a perspective view showing the front side of the necklace after the temperature change according to an embodiment.

Here, the pendant 10 shown in FIGS. 1 and 3 is also the front side.

According to the above-described embodiment, the color-changing material of the reversible Zion pigment applied to the color-changing layer 102 that is the front side of the pendant 10 is black, and the color-changing temperature is 30°C.

At this time, when the temperature in contact with the color-changing layer 102 is less than 30° C., the pendant 10 exhibits a black color as shown in FIG. 1 . This is a phenomenon in which the contact temperature does not reach the discoloration temperature, so the solvent in the microcapsules is present in a solid state, and the discoloration materials exist in combination with each other, resulting in an existing color.

On the other hand, when the contact temperature is 30° C. or higher, the color-changing layer 102 becomes transparent, and the hidden message layer 101 is visible as shown in FIG. 3 . This is a phenomenon in which the contact temperature reaches the discoloration temperature, the solvent in the microcapsule changes to a liquid state, and the bonding of the discoloration material is separated and appears transparent. In addition, at a temperature of 30° C. or higher, the color-changing layer 102 may become more transparent as the temperature increases.

As such, due to the characteristics of the Zion pigment used in the color-changing layer 102, the front surface of the pendant 10 may exhibit an opaque color depending on the temperature change to which it is contacted, or it may change to be transparent so that the message layer 101 can be seen. .

Returning to FIG. 2 again, the configuration of the color-changing layer 102 will be described in detail.

The above-described reversible Zion pigment is mixed with enamel to form the color-changing layer 102 in the form of a paint. First, when mixing the paint, when the Zion pigment is a powder type, the Zion pigment is mixed in an amount of 5 to 30 parts by weight based on the total weight of the paint. When the Zion pigment is mixed with the enamel paint and used, when the Zion pigment is mixed in the above-described parts by weight, the effect of discoloration can be economically confirmed. If the Zion pigment is mixed in less than 5 parts by weight, the discoloration effect may be lowered, and mixing in more than 30 parts by weight is uneconomical formulation. However, when the Zion pigment is an emulsion type, the Zion pigment may be mixed in an amount of 6 to 30 parts by weight based on the total weight of the paint.

Here, the paint may further include carbon nanotubes in 0.3 to 1.0 parts by weight based on the total weight. The electrical conductivity of carbon nanotubes is similar to that of copper, and the thermal conductivity is similar to that of diamond, improving the reaction rate of the Zion pigment.

The discoloration layer 102 may be a layer formed by directly applying the above-described paint on the message layer 101 . In addition, the color-changing layer 102 may be a layer formed by attaching the message layer 101 in the form of a film.

When the enamel paint including the Zion pigment is directly applied on the message layer 101, the paint goes through a drying process. To prevent cracking, it is first dried at a temperature of 50° C. for 3 to 5 minutes, and for complete drying, it is dried secondarily at a temperature of 100° C. to 150° C. for 30 minutes.

The discoloration layer 102 may be formed in the form of a film attached to the message layer 101 in order to prevent it from being easily peeled or scratched. When formed in the form of a film, first, an enamel paint including the above-described Zion pigment is applied on the film. For the film, a rigid plastic film such as Oriented Polypropylene (OPP), Polyethylene Terephthalate (PET), or an acrylic film may be used. After the paint is applied, the film goes through a paint drying process as well. After the paint is dried, the film passes through a pair of high-pressure rollers and is pressed, and is manufactured including the process of laminating. In addition, in order to be attached on the message layer 101, it includes an adhesive layer on one surface.

Although not shown in FIG. 2, after the above-described base portion 100, message layer 101, and color-changing layer 102 are sequentially stacked, the edge portion 103 surrounds all the stacked side surfaces of the pendant 10. form the appearance of The rim portion 103 is made of a metal material such as gold, platinum, or silver to prevent damage to the pendant 10 .

On the other hand, the above-mentioned pendant 10 may be provided in various accessories such as earrings and bracelets as well as the necklace 1 .

According to embodiments, the pendant 10 is provided in various accessories such as the necklace 1, earrings, or bracelet, and the color may change according to the temperature at which the front surface of the pendant 10 contacts. As the color changes to transparent, a hidden message becomes visible, giving the wearer a special meaning. In addition, the back side is made of natural mother-of-pearl, so various productions are possible depending on the situation. With the pendant 10 that changes according to the temperature, it is possible to give a unique and meaningful gift to a loved one, family, lover, or friend, to give fun, and to satisfy the needs of consumers.

As described above, although the embodiments have been described with reference to the limited drawings, various modifications and variations are possible from the above description by those of ordinary skill in the art. For example, the described techniques are performed in an order different from the described method, and/or the described components of structures, devices, etc. are combined or combined in a different form than the described method, or other components or equivalents are used.
