Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a decorative structure such as a compact having a border pattern rich in glitter.

[Conventional technology]

Generally, as a decorative body having an end face rich in glitter,
There is a sheet-like material made of transparent resin containing fluorescent dye pigment. This type of sheet-like material has the function of absorbing ultraviolet rays in the invisible region through the action of the above-mentioned fluorescent dyes and pigments, converting them into visible light, and emitting them. Since visible light is added and radiated from the end face, the end face appears to shine. Further, from this end surface, the effect of the fluorescent dye pigment contained in the length direction of the sheet-like body is strongly expressed, and the end surface appears darker and brighter than other parts. The sheet-like material having such characteristics has a special aesthetic appearance because its end surfaces appear to shine and are darker than other parts due to the action of the ultraviolet-converted visible light and the concentration of fluorescent dye and pigment. It is used for miscellaneous goods, toys (for example, name tags and nameplates), etc. However, such sheet-like objects are flat, and even if the end faces appear bright and dark, the entire surrounding end faces cannot be seen at the same time, and the end faces face downward. Sometimes you can't see the edge.

[Problem that the invention seeks to solve]

As mentioned above, sheet-shaped decorations containing fluorescent dye pigments have the above-mentioned restrictions on their aesthetic appreciation, so their use is limited to the above-mentioned miscellaneous goods, toys, etc. The reality is that it has not yet been used for any other purpose.
It is desired to expand the range of its application.

This invention was made in view of the above circumstances, and it applies decorative bodies containing fluorescent colorants such as the above-mentioned fluorescent dyes and pigments to a wide range of uses, such as cosmetic bags, caps, and accessories, to create beautiful and beautiful objects. The purpose is to provide a border pattern with rich glitter.

[Means for solving problems]

In order to achieve the above object, the decorative structure of the present invention includes:
The end portion of the transparent resin molded body containing the fluorescent colorant or the wall surface of the uneven portion is formed into an inclined surface, and the inclined surface is formed as a reflective surface.

Next, this invention will be explained in detail.

FIG. 1 provides a detailed explanation of the invention. In the figure,
1 is a transparent sheet-like molded product containing a fluorescent colorant, and is made of a transparent resin. The end face of this transparent sheet-like molded product 1 is formed into a downwardly inclined surface, and the inclined surface becomes a reflective surface 2 by metal plating. Light incident from one end face travels inside the end face in a straight line as indicated by the arrow, is reflected by the reflective surface 2 on the other end face 1a, and travels upward to be identified by the naked eye 3.On the other hand, fluorescent coloring A part of the light that enters the inside of the transparent sheet-like molded body 1 from the surface thereof is reflected by the reflective surface 2 while repeating total reflection inside the sheet-like molded body 1 as shown by arrow B, and is reflected by the reflective surface 2, and becomes the refracted light A. In this case, the inclination of the upward reflecting surface 2 is determined by two angles θ and 2 between the center line of the transparent sheet-like molded body 1 and the reflecting surface, as shown in FIG. The angle θ′ with the larger value among θ′ is an obtuse angle, especially 100 to 150
A setting in the range of 100° will give good results. and,
In the transparent sheet-like molded article 1 containing a fluorescent colorant, as mentioned above, the fluorescent colorant converts the invisible ultraviolet rays of the incident light into visible light, which is added to the normal visible light. and reaches the other end 1a, and from the end face 1a, the effect of the fluorescent colorant distributed in the length direction is strongly expressed, so that the reflective surface 2 of the end face 1a is exposed to the incoming visible light and All of the fluorescent colorant molecules are reflected, and this is reflected from the surface of the transparent sheet-like molded product 1.
Through the sheet-like molded body 1, the color appears darker than other parts, and moreover, it appears to shine as if it were dotted. Therefore, even if the other end surface 1a is facing downward as in the sheet-like molded article 1 and the end surface 1a is not directly visible to the naked eye, the brightness and dark color of the end surface will be the same as that of the reflective surface. 2, and the entire outer peripheral end surface of the sheet-like molded body 1 can be seen at the same time. As a result, the outer periphery of the sheet-like molded object 1 shines like dots. A band of eyebrow color appears, forming a beautiful border pattern.

As a result, the present invention extends the scope of application of the above-mentioned fluorescent coloring-containing decorations not only to flat plate-like items such as name tags and nameplates, but also to caps, compacts, toys, accessories, etc. It was possible to expand it to something with a three-dimensional shape. □ The transparent resin molded article containing a fluorescent colorant used in this invention is a dry type, thermosetting, or thermoplastic transparent resin (including not only completely transparent but also translucent), a fluorescent dye, and a fluorescent pigment. It can be manufactured by blending a fluorescent coloring agent such as, for example, and performing coating and drying in a sheet form, casting hardening, lamb molding, or the like. Examples of the dry transparent resin include nitrocellulose (also known as collodion liquid) and polyvinyl alcohol, and examples of the thermosetting transparent resin include unsaturated polyester resin and diethylene glycol bisallyl carbonate.
-, acrylic ultraviolet curable resin, etc. Examples of thermosetting transparent resins include polycarbonate, polymethacrylate transparent ABS resin, polyvinyl chloride 5 polyvinyl acetate, polyacrylnidonyl, etc. alone or copolymers; Coalescence (ethylene-vinyl acetate, ethylene-ethyl acrylate,
Ethylene-acrylic copolymers, propylene-ethylene copolymers) can also be used.

Among these, polycarbonate 1-
．． Polymethacrylenide, polyvinyl acetate, ethylene copolymers, etc. are suitable, and using a resin containing an acid component (terephthalic acid, acrylic acid) will bond with the fluorescent dye pigment and improve the durability of the system. This is more suitable from this point of view.

As the fluorescent colorants such as the fluorescent pigments and dyes mentioned above, known ones sold by Chiha-Geigy, IC1, Mitsui Chemicals, etc. can be used. In the transparent resin molded article containing the fluorescent colorant as described above, the concentration of the fluorescent colorant is set to 3% by weight (hereinafter abbreviated as "%") or less. More preferably 0.0 OS to 0.3%
That's about it.

Setting within this range will give the most favorable results.

In addition, the reflective surface 2 of the fluorescent colored diagonally filled transparent resin molded body
is formed by pasting metal foil such as aluminum foil or copper foil on the end surface 1a, or by applying metal plating to the end surface 1a.
Alternatively, it can be carried out by applying a paint containing metal foil powder, or by applying a silver nitrate solution and sipping. In this case, the thickness of the metal film forming the reflective surface is set to 0.
When the thickness is set within the range of 0.01 to 50 μm, good results can be obtained in forming a border pattern.

〔Example〕

Next, an example in which the present invention is applied to a cosmetic compact will be described. FIG. 3 shows the appearance of the cosmetic compact, and FIG. 4 shows its partial section. In these figures, 5 is a lid made of transparent polymethacrylate containing fluorescent dye, 6 is a mirror provided on the back side of the lid 5, 7 is a container body made of white ABS resin, and 8 is the container body made of white ABS resin. A middle frame is housed inside, and 9 is a solid cosmetic with a tray 10 housed in the middle frame 8. The downward end face of the end of the lid body 5 made of the fluorescent colored diagonal resin is formed into a reflective surface 5a by metal plating.
Dark, dot-like shining shape B reflected in a (Visible light incident from the surface and sides of the lid + UV-converted visible light)
is visible through the lid 5 from the surface of the transparent lid 5. As a result, a beautiful pattern that is darker than the color of the lid 5 and shines like dots is formed in the portion 5a indicated by the broken line in FIG. A very beautiful border pattern appears.

FIG. 5 shows the appearance of another embodiment, and FIG. 6 shows its cross section. In these figures, reference numeral 11 denotes a lid made of ABS resin, which is formed with a recessed part in the center, and a sheet-like molded body 12 made of transparent polycarbonate having a fluorescent pigment is placed in the recessed part by undercut bonding and ultraviolet bonding. It is attached by sonic bonding, adhesive bonding, etc. The end surface of this sheet-like molded body 12 is formed into a downwardly inclined surface, and becomes a reflective surface 12a by vapor deposition of metal. Reference numeral 13 indicates a mirror disposed in the center of the interior of the lid body 11, and reference numeral 14 indicates a container body made of ABS resin, in which the cosmetics 1 housed in the dish body 15 are stored.
6 is included.

In this cosmetic compact, the reflective surface 12a of the end surface 12a of the sheet-like molded body 12 reflects the dark, shining state of the end surface 12a, as shown by the diagonal lattice in FIG. A dark colored border pattern is formed on the outer periphery of the body 12, which shines as if dotted.

FIG. 7 shows an embodiment in which the present invention is applied to a mood lighting device. In the figure, reference numeral 17 denotes a dome-shaped cover made of a transparent resin molded with fluorescent dye, and its lower end surface is formed as a reflective surface 17a.

18 is a base that supports the dome-shaped cover 17.

19 is a light bulb disposed within the dome, and 20 is a lead wire for supplying power to it.

In this lighting fixture, the light from the light bulb 19 passes through the cover 17 and irradiates the surrounding area to form a soft light area, and the light from the light bulb I9 gathers on the end face of the cover 17, which is reflected by the reflective surface 1.
7a, the bottom of the dome-shaped cover 17 shines like dots along its circumference, giving it an extremely beautiful appearance.

FIGS. 8 and 9 show an embodiment in which the present invention is applied to a cap for a cosmetic container. This cap has a metal reflector 2 on the circumferential surface of a fluorescent dye transparent resin molded body 19.
0 is embedded, and its reflective surface 20a forms a border pattern both when the cap is put on and when it is taken off.

FIG. 10 shows an embodiment in which the present invention is applied to a pendant. In this pendant, a metal reflector 22 is embedded in a main body 21 made of fluorescent dye transparent resin, and a border pattern is formed by the reflective surface 22a of the metal reflector 22.

The structure of the fluorescently colored plastic molded article and the form of its reflective surface may be changed to those shown in FIGS. 11 to 13. That is, in FIG. 11, the sheet-like fluorescent colorant human molded body 30 is formed into two layers, one layer 30a being light blue and the other layer 30b being pink.

As a result, the light emitted through the reflective surface 30C has gray in addition to light blue and pink.

That is, a portion of the light emitted from the pink layer 30b is reflected by the reflective surface, passes through the light blue layer 30a as shown by arrow C, and becomes gray. This is because pink and light blue are complementary colors, so when pink light passes through the light blue layer 30a, it becomes gray light. 12th
In the figure, pearl pigments or metal small cylinder pieces are dispersed near the end face of a sheet-like fluorescent colorant molded body 30, thereby causing diffused reflection and improving brightness. In FIG. 13, fine irregularities are formed on the surface of the reflective surface 30c, and the light reflected from the nonconforming surface 30C is diffusely reflected by the fine irregularities to improve brightness.

In the above embodiment, a reflective surface is formed on the end surface of the fluorescently colored plastic molded product to form a border pattern, but as shown in FIGS. 14 to 16, the transparent cosmetic compact A laminate 41a of a plurality of fluorescent-colored transparent resin vacuum-formed sheets 41 is adhered to the transparent resin lid 40, the end surfaces of which are inclined upward as shown in FIG. 15, and the slanted end surfaces 41b form a border. A pattern may also be formed. In the figure, 42 is an opaque resin backing material, 43 is a mirror, 44 is a container body, and 45 is a cosmetic contained in a dish body 46 and fitted in the container body 44. In addition, as shown in FIGS. 17 and 18, the transparent resin M40 of the cosmetic compact is
A fluorescently colored transparent resin vacuum-formed sheet 41 having partially grooved grooves on the back side is provided, and this is coated with an opaque resin backing material 42.
The dark colored glitter state appearing on the four sloped surfaces of the back surface of the sheet 41 may be made visible from the outside through the transparent resin M40. The other parts of the compact are the same as the compact shown in FIG. 15.

Further, the present invention can be applied not only to the above-mentioned articles but also to all articles requiring aesthetic elements such as toys and accessories.
