Description

[Detailed Description of the Invention] The present invention relates to a beautiful and strong decorative article such as a buckle for a band or a pendant, in which a transparent material is coated on the outer surface of a decorative substrate.

Traditionally, to decorate the surface of buckles for bands and other pendants, letters, figures, and other pictures have been printed directly on the surface of the substrate, or decorative stickers with such figures and pictures have been attached. There are also those with three-dimensional markings on the substrate surface.

However, stamping is too expensive for inexpensive products, and decorative stickers are cheap but lack a three-dimensional effect, and
Contamination due to friction was likely to occur. Therefore, in order to enhance the three-dimensional effect of such inexpensive decorative stickers, it is common practice to cover the surface of the sticker with a transparent resin. However, the biggest drawback in this case is that when the decorative sticker is pasted onto the substrate, a very small amount of air gets trapped between the sticker and the substrate, and this is heated by the superheated molten resin used for resin coating. As a result, the air trapped inside expands to form bubble-like air pockets, which are clearly visible in the transparent resin coat and often result in products of extremely poor quality, resulting in poor product yields and being uneconomical.

Therefore, the present invention aims to provide a decorative item that does not generate bubbles on the inner surface when resin coating is applied using such a decorative seal.

That is, the most important feature is that pores are provided on the desired decorative surface to which the decorative sticker is attached, so that air from the adhesive surface escapes to the back surface.

To explain the example shown below, the substrate 1 of the buckle 5 or pendant 6 for a band
A very slight indentation is provided in the front part, holes 4, 4, etc. are bored in the appropriate places, and an adhesive decorative sticker 3 with an appropriate design or picture is pasted thereon, and the decorative sticker is A transparent body 2 made of epoxy resin or the like having a high refractive index is integrally formed by covering the substrate 1 and covering the substrate 1.

Incidentally, in order to enhance the three-dimensional effect, it is desirable that the surface of the transparent body 2 be formed as curved as possible.

In the band buckle shown in FIG. 1, the substrate is a metal plate, but in the pendant 6 shown in FIGS. 2 and 3, the substrate 1 may be made of a synthetic resin other than metal. However, in this case, it is necessary to use a resin material for the substrate that does not undergo thermal deformation depending on the forming temperature of the transparent resin.

As described above, when the surface of the decorative sticker pasted on the substrate 1 is covered with epoxy resin,
The air trapped between the decorative seal 3 and the substrate 1 is discharged to the back side from the pores 4, 4 provided in the substrate 1 under the pressure applied when the transparent resin is applied, and can be trapped inside after molding. Therefore, the transparent resin does not generate any air bubbles, so the designs, pictures, etc. printed on the decorative seal surface stand out vividly with a three-dimensional effect due to the optical effect of the resin, further enhancing the decorative effect. Moreover, since air does not get trapped in the adhesive surface, it has good adhesion and is strong, and there is no generation of defective products due to air bubbles as in the past, so it is extremely efficient and economical, and is suitable for mass production. Furthermore, the decorative seal is completely isolated from the outside by a transparent coating, which protects the decorative pattern surface, and is a highly practical device with many excellent effects.
