Decorative film and outer casing using the decorative film

The present invention relates to a decorative film and an outer casing using the decorative film.

In-mold decoration is a technique widely used in the manufacture of plastic housings. In the process of applying the in-mold decoration to manufacture the plastic shell, the decorative film is attached to the mold wall of the injection molding mold, and when the plastic is injection molded, the decorative film is bonded to the molten plastic, and after cooling, the plastic shell is integrally formed. . Generally, the decorative film needs to have a certain decorative pattern. The decorative pattern is more often a screen-like pattern design. However, the sieve pattern of the conventional decorative film is formed by printing ink, and the pattern formed by printing the ink is a flat pattern, and the decorative effect is relatively monotonous.

In view of the above, it is necessary to provide a decorative film having a mesh pattern of a multi-layer color.

In addition, it is necessary to provide an outer casing using the decorative film.

A decorative film comprising a first decorative layer and a second decorative layer in contact with the first decorative layer, the first decorative layer is provided with a plurality of first decorative holes, the second decorative layer Forming a plurality of second decorative holes, the first decorative holes are offset from the second decorative holes, and the first decorative layer is a transparent or translucent colored plastic film.

An outer casing comprising a base body and a decorative film combined with the base body, the decorative film comprising a first decorative layer and a second decorative layer conforming to the first decorative layer, the first Decorative layer a first decorative hole, the second decorative layer is formed with a plurality of second decorative holes, the first decorative hole is offset from the second decorative hole, and the first decorative layer is a transparent or translucent colored Plastic film.

Compared with the prior art, the decorative film of the present invention adopts a double-layer decorative layer, and the double-layer decorative layer is respectively formed with a first decorative hole and a second decorative hole, through the first decorative hole and the first Two decorative holes are used to achieve the contrast between the first decorative layer and the second decorative layer, thereby obtaining a mesh-like pattern effect having a multi-layered three-dimensional effect.

Referring to FIG. 1 and FIG. 2, the outer casing 100 of the preferred embodiment of the present invention includes a decorative film 10 and a base 13 injection molded on the decorative film 10.

The decorative film 10 includes a first decorative layer 11 and a second decorative layer 12 that is in contact with the first decorative layer 11.

The first decorative layer 11 can be a translucent or transparent colored plastic film. A plurality of first decorative holes 112 are defined in the first decorative layer 11. The first decorative aperture 112 can be circular, triangular, square, or other geometric figure. The plurality of first decorative apertures 112 are preferably arranged in an array.

The second decorative layer 12 can be a translucent or transparent colored plastic film. A plurality of second decorative holes 122 are defined in the second decorative layer 12. The second decorative aperture 122 can be circular, triangular, square, or other geometric figure. The second decorative apertures 122 can be arranged in the same array as the first decorative apertures 112.

The first decorative layer 11 is bonded to the second decorative layer 12 by thermoforming. After the first decorative layer 11 and the second decorative layer 12 are attached, the first decorative hole 112 and the second decorative hole 122 are mutually offset, that is, the first decorative hole 112 and The vertical projections of the second decorative apertures 122 in the first decorative layer 11 or the second decorative layer 12 are offset from one another.

The decorative film 10 can be formed by the first decorative hole 112 of the first decorative layer 11 and the second decorative hole 122 of the second decorative layer 12 respectively to form a color contrast between the first decorative layer 11 and the second decorative layer 12, thereby obtaining a sieve. Mesh pattern and multi-layered three-dimensional color effect. Preferably, the first decorative layer 11 is different in color from the second decorative layer 12, so that a more conspicuous screen pattern can be obtained.

The base 13 is formed by injection molding of an injection molding material, which may be polyethylene, polycarbonate, acrylonitrile-styrene-butadiene copolymer, polymethyl methacrylate or polyparaphenylene. Any of ethylene formate, polyvinyl chloride resin and silicone. The base 13 may be combined with the first decorative layer 11 of the decorative film 10 by injection molding or may be combined with the second decorative layer 12 of the decorative film 10. In this way, a screen pattern and a multi-layered three-dimensional color effect outer casing can be obtained.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
