Description

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

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

In general, the term "pendant" refers to an ornament that is attached to an accessory such as a necklace, earring, or bracelet to make the wearer's appearance stand out. Since ancient times, people have worn various accessories such as necklaces and earrings with pendants on their bodies, creating a style that differentiates them from others and expressing their beauty.

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

On the other hand, there are various pendants that are excellent in terms of aesthetics, but the pendants that give special meaning to the wearer are limited. In order to give meaning to accessories, special letters are engraved on the exterior of the pendant or various birthstones are placed. However, since such pendants are in a state where letters and jewelry are always exposed to the wearer, the freshness and mystery of such a pendant 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 characteristics of the material, and there is a limitation in giving a special meaning to the wearer. Therefore, a pendant that continuously gives a special meaning to the wearer fresh and capable of various presentations is required.

An object of the embodiment is to provide a pendant and a necklace including the same, in which a message giving a special meaning to a wearer is displayed by changing color according to a contact temperature.

The problems to be solved in the embodiments are not limited to the problems mentioned above, and other problems that are not mentioned will be clearly understood by those skilled in the art from the following description.

A pendant whose color changes according to temperature according to an embodiment and a necklace including the same will be described.

The pendant according to an embodiment is formed on the base portion, on one surface of the base portion, and is formed on the message layer including an image or text, and is formed on the message layer and is opaque so that the message layer is not visible when the contact temperature is less than 30°C. It is composed of a discoloration layer including a reversible Zion pigment that exhibits one color and changes color to be transparent when the temperature is 30°C or higher.

According to one side, the color change layer may be a layer formed on the message layer in the form of a film to which an enamel paint including Zion pigment is applied. In addition, the color change layer may be a layer formed by directly applying an enamel paint including Zion pigment on the message layer.

According to one side, the enamel paint contains 5 to 30 parts by weight of Zion pigment based on the total weight. The enamel paint is first dried at a temperature of 50° C. for 3 to 5 minutes, and secondary drying at a temperature of 100° C. to 150° C. for 30 minutes.

According to one side, the base portion is formed of natural mother-of-pearl or a mother-of-pearl, which is a kind of natural mother-of-pearl.

According to one side, the message layer is made of an opaque material so that the base portion is not exposed, and the message is included in the form of ink or intaglio on the opaque material.

According to one side, the pendant further includes an edge portion made of a metal material, and the edge portion is formed to cover all sides in a state in which the base portion, the message layer, and the color change layer are stacked.

A necklace including a pendant whose color changes according to temperature according to an exemplary embodiment includes a chain worn on a wearer's neck, a pendant detachably provided on the chain, and a pendant whose color changes according to temperature and a message appears. The pendant has an opaque color so that the message layer is not visible when the base portion, the message layer including an image or text, and a contact temperature of less than 30° C. is formed on one surface of the base portion and the base portion. , It is configured to include a discoloration layer containing a reversible Zion pigment that changes color to be transparent when the temperature is 30°C or higher.

As seen above, according to the embodiments,

A message appears as the color changes according to the temperature at which the front surface of the pendant touches, and can give a special meaning to the wearer.

Also, a message appears according to the temperature on the front side, while the back side is made of natural mother-of-pearl, so it is possible to produce various displays depending on the situation.

In addition, it is the only special gift in the world to beloved family members, lovers, and friends, and it can also provide fun and satisfy the needs of consumers.

Unless otherwise stated, the description of one embodiment may be applied to other embodiments, and a detailed description will be omitted in the overlapping range.

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

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

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

Referring to FIG. 1, the necklace 1 includes a pendant 10, a ring 11 and a chain 12.

Here, the pendant 10 refers to an ornament that is attached to an accessory such as a necklace, earring, or bracelet to make the wearer's appearance stand out.

A message appears as the color of the front surface of the pendant 10 changes to be transparent according to the contact temperature. 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 portion 11 is provided on one side of the rim portion 103 formed to cover all sides of the pendant 10 on the outside of the pendant 10.

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

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

2 is a cross-sectional view showing a part 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 portion 100, the message layer 101, and the color change layer 102 are stacked.

The base portion 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, a kind of natural mother-of-pearl. However, the type of the base part 100 is not limited to pearl pads, and conch pads or red pads may be used.

The message layer 101 includes an image or text, and is formed on one surface of the base portion 100. At this time, the message layer 101 is made of an opaque material so that the base portion 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.

Images or characters included in the message layer 101 may be printed with black ink. The printing method may include a message desired by the wearer by, for example, a silk printing method. In addition, the message can be engraved not only in print, but also in the form of a color engraved intaglio. In this way, a variety of ways to put a message are possible. The color is also not limited to the above-described black, and various colors in which a 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 phrases are possible only within the range that can be included in the area of the message layer 101.

The color change layer 102 is formed on the message layer 101 and becomes the front surface of the pendant 10.

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

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

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

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

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

At this time, when the temperature in contact with the color change layer 102 is less than 30° C., the pendant 10 exhibits a black color as shown in FIG. 1. Since the contacted temperature does not reach the discoloration temperature, the solvent in the microcapsules is present in a solid state, and the discolored substances are bonded to each other to present the existing color.

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

In this way, due to the characteristics of the Zion pigment used in the color change layer 102, the front surface of the pendant 10 may exhibit an opaque color according to a change in contact temperature, or change to be transparent, so that the message layer 101 may 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 change layer 102 in the form of a paint. First of all, when the Zion pigment is a powder type, the paint is mixed in 5 to 30 parts by weight of 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. When 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 an uneconomical formulation. However, when the Zion pigment is an emulsion type, the Zion pigment may be mixed in 6 to 30 parts by weight of the total weight of the paint.

Here, the paint may further include carbon nanotubes in an amount of 0.3 to 1.0 parts by weight of the total weight. The electrical conductivity of carbon nanotubes is similar to that of copper, and the thermal conductivity of carbon nanotubes is similar to that of diamond, which improves the reaction rate of Zion pigments.

The color change layer 102 may be a layer formed by directly applying the above-described paint on the message layer 101. In addition, the color change layer 102 may be a layer formed by being attached to the message layer 101 in the form of a film.

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

The color change 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 off 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. The film may be a rigid plastic film such as oriented polypropylene (OPP), polyethylene terephthalate (PET), and acrylic film. After the paint is applied, the film is similarly subjected to a paint drying process. After drying of the paint, the film is compressed while passing through a pair of high-pressure rollers to produce a laminating process. In addition, to be attached to the message layer 101, it includes an adhesive layer on one side.

Although not shown in FIG. 2, after the base portion 100, the message layer 101, and the color change layer 102 are sequentially stacked, the edge portion 103 covers all of the stacked sides, and the pendant 10 Forms the appearance of. The rim portion 103 is made of a metal material such as gold, platinum, silver, etc. to prevent the pendant 10 from being damaged.

On the other hand, the above-described pendant 10 may be provided not only in the necklace 1 but also in various accessories such as earrings or bracelets.

According to embodiments, the pendant 10 is provided in various accessories such as a necklace 1, an earring or a bracelet, and the color may change according to a temperature at which the front surface of the pendant 10 contacts. As the color changes to transparent, hidden messages become visible and give special meaning to the wearer. In addition, the back side is made of natural mother-of-pearl, so it can be displayed in various ways depending on the situation. With the pendant 10 that changes depending on the temperature, it is possible to provide only one meaningful gift to a loved one, a lover, or a friend, and can also provide fun and satisfy the needs of consumers.

As described above, although the embodiments have been described by the limited drawings, various modifications and variations are possible from the above description to those of ordinary skill in the art. For example, the described techniques are performed in a different order from the described method, and/or components such as the described structure, device, etc. are combined or combined in a form different from the described method, or in other components or equivalents. Even if substituted or substituted by, appropriate results can be achieved.
