Description

The present invention relates to chopsticks colored on the surface of the body, and more particularly to colored chopsticks capable of imparting a transparent feeling like glass work, a three-dimensional effect, and a change in shade (gradation) of color.

Since the shape of chopsticks is almost constant, the body of chopsticks can be colored or patterned with lacquer or paint to enhance the decorativeness, or patterns such as animals, plants and landscapes can be added to the material of wood. Ingenuity such as emphasizing the grain and texture has been made since ancient times. In addition, attempts have been made to make the color and pattern of the surface of the body appear three-dimensional by forming irregularities on the body, and to create a sense of quality by pasting gold leaf or silver leaf. In recent years, like the chopsticks described in Patent Document 1, unevenness is formed on the body of the left and right chopsticks so as to mesh with each other, and by coloring the unevenness, a beautiful pattern is formed when the chopsticks are not used. The ones that have been proposed.

Further, Patent Document 2 proposes chopsticks in which a paint whose color changes depending on temperature is applied to a body portion.
Further, Patent Document 3 discloses a technique of winding a heat-shrinkable pattern tube around a body and heating it to form a pattern on the body, and also by stacking a plurality of the pattern tubes and winding them around the body. It has also been proposed to form a multi-layer pattern on the body.

Utility Model Registration No. 3156377 Jitsukaihei 6-15574 (see summary) Japanese Unexamined Patent Publication No. 2012-29749 (see the description of the abstract)

The techniques described in these documents should be noted as proposals for enhancing the design of chopsticks and expanding their variations, but there is a desire to further expand the range of designs such as coloring and patterns.
The present invention was made to meet such demands, and by supporting the three-dimensionality, transparency, and change of shade in the coloring, the design of the chopsticks is further enhanced, and the variation such as coloring is further expanded. The purpose is to provide colored chopsticks that can be used.

In order to solve the above problems, the colored chopsticks of the present invention have a highly reflective layer formed on the surface of the body of the chopsticks and mirror-reflecting external light, and a pigment or a transparent base material as described in claim 1. It has a translucent colored substrate layer formed by raising a colored substrate colored by adding a dye on the surface of the highly reflective layer, and the translucent colored substrate layer has a preset color. And, depending on the thickness of the colored base material from the peripheral portion to the central portion, the shade of the color reflected by the highly reflective layer and transmitted through the colored base material layer changes. It is configured to generate a gradation.

As a guideline, the reflectance of the high-reflecting layer is such that a metal such as gold, silver, or aluminum is smoothed and specularly reflected. According to the present invention, a colored base material layer in which a pigment or a dye is added to a transparent base material such as a resin such as acrylic or glass is sterically raised and formed on a high reflection layer that reflects external light with a high reflectance. In addition, by forming the colored base layer in a raised manner so that the change in color shade (gradation) can be visually recognized from the peripheral portion to the central portion, a bright, transparent and three-dimensional effect like glass work can be obtained. Coloring with varying shades can be applied to the body.

The highly reflective layer may have a gold sheet (including gold foil), a silver sheet (including silver foil), an aluminum sheet (including aluminum foil), or the like attached to the surface of the body, or plated with these metals. It can be formed by applying it to the surface of the body, thermally transferring it, or selecting a highly reflective metal such as gold, silver, or aluminum as the material for forming the body.

Since the colored base material layer is raised and formed on the highly reflective layer and is three-dimensional, it is possible to greatly expand the variation of coloring. For example, as described in claim 2, a plurality of the colored substrate layers are formed on the surface of the highly reflective layer, and the adjacent colored substrate layers have different colors or the same color but different brightness or saturation. This makes it possible to add various colorful three-dimensional patterns to the chopsticks. Further, as described in claim 3, by superimposing and arranging the adjacent colored base materials on a part of the peripheral portion, the overlapped portion can have a color different from that on both sides thereof.

Further, as described in claim 4, one colored base layer is formed by continuously changing the thickness of the colored base layer from one peripheral portion to the other peripheral portion. It is possible to continuously provide parts having different brightness in the interior.
Further, as described in claim 5, by providing the highly reflective layer having a different reflected light color on the surface of the body, it is possible to further expand the variation of coloring in addition to the above.

Preferred embodiments of the present invention will be described in detail with reference to the drawings.
1 to 4 show the first to fourth embodiments of the colored chopsticks of the present invention, and FIGS. 1 to 4 are partial cross-sectional views of the body of the chopsticks, and FIG. 5 shows examples of colors and pattern patterns formed on the colored chopsticks of the present invention. FIG. 6 is a photograph showing an example of the colored chopsticks of the present invention. In the illustrated example, chopsticks having a square cross section are taken as an example, but the present invention can be applied to chopsticks having various cross-sectional shapes such as a circle and a polygon.

[First Embodiment]
As shown in FIG. 1, a high-reflection layer 2 is formed on the surface of the body 1a of chopsticks by a metal such as gold, silver, or aluminum that reflects external light with high reflectance. The highly reflective layer 2 can be formed, for example, by plating the surface of the body portion 1a with these metals, or by selecting these metals as the material of the body portion 1a. In this case, it is advisable to appropriately perform polishing or buffing so that the surface of these metals is smoothed as much as possible to obtain a reflectance having a high degree of specular reflection.
Further, for example, the metal sheet (including the metal foil) having the adhesive layer is placed on the surface of the body portion 1a, and the body is passed through the adhesive layer by thermal transfer so that the metal sheet is not wrinkled. It may be attached to the surface of the portion 1a.

A translucent colored base material layer 3 is formed on the surface of the highly reflective layer 2. The colored base material layer 3 uses a colored base material colored by adding a pigment or a dye to a transparent base material such as glass, in addition to resins such as acrylic resin, epoxy resin, polyester resin, and urethane resin. The thickness of the central portion 3b is large and the thickness of the peripheral portion 3a is small. The colored base material layer 3 has a certain width so that a change in color shade (gradation) can be visually recognized from the peripheral portion 3a to the central portion 3b in cooperation with the reflected light from the surface of the high reflection layer 2. (Width H in the left-right direction of the paper surface in FIG. 1), length (length in the same depth direction), and thickness (thickness T in the same vertical direction) are raised and formed so as to have a gradient.

As a guideline for the width H and the length, 3 mm or more can be mentioned, and as a guideline for the thickness T, 1 mm or more can be mentioned. Further, the magnitude of this change in shade is closely related to the amount of external light incident on the colored substrate layer 3 and reaching the high reflection layer 2, and the amount of the pigment or dye added to the transparent substrate is large. If the amount is too small or too small, the degree of change in the shade will be small. Therefore, the amount of the addition is adjusted so that the change in the shade is appropriate for the design of the chopsticks.

The colored base material layer 3 described above can be formed by applying the colored base material, which has been liquefied by dissolving in a solvent or the like, onto the high-reflection layer 2 by hand coating, and then drying. As shown in FIG. 1, the colored substrate can be applied by extruding the colored base material onto the high-reflection layer 2 from the nozzle N. Further, as another method, there is a method in which the colored base material is attached to the tip of the rod-shaped member and coated on the highly reflective layer 2. In this case, the shape and thickness T of the colored base material layer 3 in a plan view can be variously changed by applying the nozzle N and the rod-shaped member while moving them up and down, left and right, or in the depth direction.

FIG. 5 shows an example in which various planar colored equipment layers 3 are formed on the surface of the body portion 1a.
For example, in the example of FIG. 5A, a plurality of coloring equipment layers 3 (three in the illustrated example) having a linear peripheral edge portion 3a are formed so as to cross the surface of the body portion 1a. The plurality of coloring equipment layers 3 are arranged apart from each other, and the high reflection layer 2 is exposed between the coloring equipment layers 3 and 3.
In the example of FIG. 5B, the coloring equipment layer 3 has a circular or elliptical shape in a plan view, and a plurality of the coloring equipment layers 3 are arranged on the high reflection layer 2 at intervals. In this example, the highly reflective layer 2 is formed on the entire circumference of the body portion 1a, and the colored base material layer 3 is formed not only on the surface but also on the side surface.
Further, in the example of FIG. 5C, a plurality of irregularly shaped coloring equipment layers 3 having different shapes are formed on the high reflection layer 2. In this example, at least a part of the peripheral portion 3a of the colored base layer 3 may be formed so as to overlap with the peripheral portion 3a of another adjacent colored base layer 3.

[Second embodiment]
As shown in FIG. 2, in the second embodiment, the peripheral edge portions 3a of the adjacent colored substrate layers 3 are overlapped (the overlapped portions are indicated by reference numerals 3c). The color of the adjacent colored base layer 3 may be either a similar color or a different color. By making the adjacent colored base layer 3 a similar color but having different shades, it is possible to represent a continuous change in shade from one colored base layer 3 to the next adjacent colored base layer 3. In addition, by using a different color, it is possible to gradually change from one colored base material layer 3 to another color.

[Third embodiment]
As shown in FIG. 3, in the third embodiment, the thickness T of one colored base material layer 3 changes in height in the process from one peripheral edge portion 3a to the other peripheral edge portion 3a. By doing so, it is possible to express a complicated change in shade in one colored base material layer 3.
As described above, such a change in the thickness T can be formed, for example, by applying the nozzle N (see FIG. 1) or the rod-shaped member while moving it up and down, left and right, or in the depth direction. ..

[Fourth Embodiment]
As shown in FIG. 4, in the fourth embodiment, a plurality of highly reflective layers 2a, 2b, 2c, 2d ... With different reflective colors such as gold and silver are formed on the surface of the body portion 1a.
By changing the reflection colors of the high-reflection layers 2a, 2b, 2c, 2d ... By the cooperation between 2c, 2d ... and the colored base material layer 3, it becomes possible to further diversify the change in coloring.

Since the colored chopsticks of the present invention are configured as described above, it is possible to provide chopsticks with new patterns and colors having a three-dimensional effect, transparency and gradation as shown in the photograph of FIG. By variously combining the first to fourth embodiments, it becomes possible to provide chopsticks having extremely various designs. Further, since the colored base material layer 3 is three-dimensional, unevenness is formed on the surface of the chopsticks 1, and a non-slip effect can be obtained.

Although the preferred embodiment of the present invention has been described, the coloring chopsticks of the present invention are not limited to the above description.
For example, in the above description, a plurality of colored base layers 3 are formed, but only one may be formed on the body portion 1a as an accent.
Further, a metal such as gold, silver, or aluminum has been described as an example of the type of the high-reflection layer 2, but the metal is not limited as long as it can reflect external light with a high reflectance as high as specular reflection. ..

Further, the chopsticks 1 to which the present invention is applied can be made of any material such as resin, not only wooden but also metal.
Further, the pigment or dye added to the transparent substrate is not limited to one color, but may be a plurality of colors, and both the pigment and the dye may be added. When one color pigment or dye is used, these may be in a non-uniformly dispersed state in the transparent substrate, and when different color pigments or dyes are used, these may be completely mixed. It may be in a so-called chaotic state.
