Abstract

A molded resin product includes a design layer including a decorative layer having a first color, a shielding layer having a second color different from the first color, and a resin base layer. A cover layer formed of a polymer film is disposed close to one end of the design layer. Part of the decorative layer exposed from the shielding layer serves as an exposed region. The exposed region and part of the shielding layer constitute a pattern portion presenting a predetermined figure or character when viewed in plan through the cover layer. The rest of the shielding layer constitutes a base portion. The layer thickness of the base portion is set smaller than the layer thickness of the pattern portion in a region thereof where the shielding layer is formed.

First claim

What is claimed is:

1. A molded resin product comprising:
a cover layer formed of a polymer film;
a design layer disposed close to a lower surface of the cover layer and visible through the cover layer, wherein the design layer includes:
a decorative metal layer, wherein the metal layer allows for passing of radio waves without being interfered;
a shielding layer having a color different from that of the metal layer, the shielding layer covering a part of the metal layer forming a shielded region of the metal layer and an exposed region of the metal layer exposed from the shielding layer when viewed in plan through the cover layer; and

a resin base layer disposed between the cover layer and the design layer, covering the shielding layer and the exposed region of the metal layer,
wherein the exposed region and a part of the shielded region constitute a pattern portion presenting a predetermined figure or character when viewed in plan through the cover layer and the resin base layer,
wherein a remaining part of the shielded region constitutes a plain base portion when viewed in plan through the cover layer and the resin base layer, and
wherein a total thickness of the base portion is smaller than a total thickness of the pattern portion where the part of the shielded region informed and the total thickness of the base portion is larger than a total thickness of the pattern portion in a region where the exposed region is formed.

2. The molded resin product according to claim 1 , wherein a layer thickness of the resin base layer where the base portion is formed is smaller than a layer thickness of the resin base layer where the part of the shielded region is formed.

3. The molded resin product according to claim 2 , wherein the layer thickness of the resin base layer where the base portion is formed is larger than a layer thickness of the resin base layer where the exposed region is formed.

4. The molded resin product according to claim 3 , wherein the exposed region is formed as protruding above a surface of the shielded region.

5. The molded resin product according to claim 1 , further comprising a holding layer adjacent to the design layer, disposed below the metal layer.

6. The molded resin product according to claim 1 , wherein the shielded layer is a print layer.

7. The molded resin product according to claim 6 , wherein the color is black.

8. The molded resin product according to claim 6 , wherein the resin base layer comprises an ultraviolet curable resin.

9. The molded resin product according to claim 6 , wherein a percentage of elongation of the resin base layer is about 1-100% and a percentage of elongation of the print layer is 1-200%, wherein the percentage elongation of the print layer is higher than that of the resin base layer.

10. The molded resin product according to claim 6 , wherein a Shore D hardness of the resin base layer is about 60-90 and a Shore D hardness of the print layer is about 70-90, wherein the Shore D hardness of the print layer is lower than that of the resin base layer.

11. The molded resin product according to claim 1 , further comprising:
an object joined to the base portion via a joint body.

12. The molded resin product according to claim 11 , wherein:
the object includes a protrusion protruding toward the design layer, and a depression hollowed relative to the protrusion; and
the depression is joined to the base portion via the joint body, and a guide body brought into contact with the protrusion is provided in the base portion.

13. The molded resin product according to claim 12 , wherein a thickness of the joint body is larger than a thickness of the guide body.

14. The molded resin product according to claim 12 , wherein the joint body and the guide body are separated from each other.

15. The molded resin product according to claim 12 , wherein the joint body is a double-sided tape, and the guide body is a single-sided tape.
