Description

  The present invention relates to a plastic cover body used for mobile phones, PDAs, portable video / audio players, and the like, and more particularly to a plastic cover body having a three-dimensional effect.

  Due to advances in science and technology, mobile phones, PDAs, and portable video / audio players have become popular in recent years. We are striving every day to strengthen the sex and to increase the willingness of young people to purchase.

As shown in FIGS. 5 and 6, the plastic cover body (90) used in the portable 3C product such as the conventional cellular phone is transferred onto the surface of the plastic plate (91) by transferring the uneven pattern with a seal. The print layer (92) is formed, and the surface of the print layer (92) is covered with a transparent film (93) having a protective action, or an uneven pattern is printed on the injection molding mold of the plastic cover body (90). And integrally formed.
According to these methods, a concavo-convex pattern can be formed on the surface of the plastic cover body (90) of the portable 3C product, and the printed layer (92) of the plastic cover body (90) exhibits a concavo-convex shape. Can provide.
In addition to the above, for example, Taiwan Utility Model Public Notice No. 544077 “Mobile phone cover body having a three-dimensional pattern” (Patent Document 1), Taiwan Utility Model Public Notice No. 586492 “three-dimensional pattern light can be emitted. ”Structure of decorative plate” (Patent Document 2), Taiwan Utility Model Certificate No. M265218 “Molding Structure of Light Emitting Three-dimensional Pattern” (Patent Document 3) and the like have been filed.

Taiwan Utility Model Notice No. 544077 Taiwan Utility Model Notice 586492 Taiwan Utility Model Certificate No. M265218

However, the plastic cover body (90) used in the above-described conventional portable 3C product is merely provided with a printed layer (92) having a concavo-convex pattern on the surface of the plastic cover body (90). Since the printed layer (92) is easily damaged or peeled off due to friction or collision during use or carrying, there is a risk that the appearance of the portable 3C product may be impaired, and a three-dimensional effect cannot be provided. The steric effect is limited.
Furthermore, when the surface of the plastic cover body (90) is not flat, there is a risk of damaging the texture when gripped.
And, the Taiwan Utility Model Public Notice No. 544077 “a mobile phone cover body having a three-dimensional pattern”, Taiwan Utility Model Public Notice No. 5864492 “Structure of decorative plate capable of emitting three-dimensional pattern light” and Taiwan Utility Model Certificate No. No. M265218 “3D pattern forming structure that emits light” employs a method of providing a laser reflected light print layer on the surface of the plastic cover body, but even in this method, the three-dimensional effect cannot be exhibited effectively, Since the laser reflected light print layer is still easily broken or peeled off, the texture when gripped as a result is impaired.

According to a first aspect of the present invention, there is provided a light-transmitting plastic plate (11), and a light-transmitting thin film layer (12) in which holes are formed at predetermined intervals on the inner surface of the plastic plate (11). And a reflective back layer (13) are provided in order, and the back layer (13) is provided with a concavo-convex pattern according to the arrangement of the holes formed in the thin film layer (12). And provide a plastic cover body
According to a second aspect of the present invention, there is provided the plastic cover body according to the first aspect, wherein an uneven pattern is formed on the surface of the back layer (13) on the plastic plate (11) side. Is,
According to a third aspect of the present invention, a plurality of recesses (131) covering the thin film layer (12) are formed on the surface of the back layer (13) on the plastic plate (11) side, and the plurality of the plurality of recesses (131) are formed. The plastic cover body according to claim 1 or 2, wherein a convex portion (132) coupled to the inner surface of the plastic plate (11) is formed at a position where the hole is disposed.

As described above, the present invention includes a light-transmitting plastic plate, a light-transmitting thin film layer in which holes are formed at predetermined intervals on the inner surface of the plastic plate, and a reflective back layer. And an uneven pattern is formed in the back layer according to the arrangement of the holes formed in the thin film layer, and an uneven pattern is formed on the surface of the back layer on the plastic plate side. Since a plurality of recesses that cover the thin film layer are formed on the surface of the layer on the plastic plate side, and a protrusion that is coupled to the inner surface of the plastic plate is formed at a position where the plurality of holes are disposed, There are the following effects.
<1> A plastic cover body according to the present invention includes a light-transmitting plastic plate, and has a light-transmitting thin film layer in which holes are formed at predetermined intervals on the inner surface of the plastic plate, and has a reflectivity. A back layer is provided in order, and the back layer has a concavo-convex pattern according to the arrangement of holes formed in the thin film layer, and the thin film layer and the light-transmitting plastic plate have a refractive action. Since the plastic cover body can have an excellent three-dimensional effect, the consumer's willingness to purchase can be further enhanced.
<2> Since the thin film layer and the back layer in the present invention are provided on the inner surface of the plastic plate having an excellent structural strength, the thin film layer and the back layer have an excellent protective effect on the thin film layer and the back layer. The thin film layer and the back surface are not damaged or peeled off due to friction, collision or dropping. Therefore, the beauty of the portable 3C product can always be maintained.
