Abstract

Provided is an injection-molded product manufactured of a synthetic resin having light permeability, the injection-molded product including a pattern structure formed on an inner surface of the injection-molded product and a coupling structure formed on the pattern structure, in which the coupling structure is hidden by the pattern structure from an outer surface of the injection-molded product. The injection-molded product may be manufactured of a transparent material so that the coupling structure or reinforcing structure, can be hidden visually. Various colors can be used in the surface treatment, such as painting or deposition, on the injection-molded product.

Claims

1. An injection-molded product manufactured of a synthetic resin having light permeability, comprising:

a pattern structure formed on an inner surface of the injection-molded product; and

a coupling structure formed on the pattern structure,

wherein the coupling structure is hidden by the pattern structure from an outer surface of the injection-molded product.

2. The injection-molded product of claim 1, wherein the coupling structure formed in the injection-molded product and the coupling structure formed in a second injection-molded product are connected to each other face-to-face such that the injection-molded product is coupled and fixed to the second injection-molded product, the second injection-molded product comprising the pattern structure and the coupling structure.

3. The injection-molded product of claim 1, wherein the pattern structure is in a shape of a band in which protruding portions and recessed portions are alternately formed in succession.

4. The injection-molded product of claim 1, wherein the pattern structure is formed such that protruding portions and recessed portions are alternately formed on the entire inner surface of the injection-molded product.

5. The injection-molded product of claim 1, wherein the pattern structure is formed of lattice patterns which consecutively protrude at least in adjacent to an edge of the inner surface of the injection-molded product.

6. The injection-molded product of claim 1, wherein the pattern structure is in a shape in which the coupling structure is consecutively formed.

7. The injection-molded product of claim 1, wherein the pattern structure is one of O shape, a zigzag shape, V shape, and + shape.

8. A device for enclosing components of a portable electronic device, comprising:

a first case and a second case,

the first and second cases having a pattern structure formed on an inner surface therein and a coupling structure integrally formed on the pattern structure via injection molding process,

wherein the first case and the second case interlocks to each other via the respective coupling structures and the coupling structure is hidden by the pattern structure from an outer surface.

9. The device of claim 8, wherein the pattern structure is in a shape of a band in which protruding portions and recessed portions are alternately formed in succession.

10. The device of claim 8, wherein the pattern structure is formed such that protruding portions and recessed portions are alternately formed on the entire inner surface therein.

11. The device of claim 8, wherein the pattern structure is formed of lattice patterns which consecutively protrude at least in adjacent to an edge of the inner surface therein.

12. The device of claim 8, wherein the pattern structure is in a shape in which the coupling structure is consecutively formed.

13. The device of claim 18, wherein the pattern structure is one of O shape, a zigzag shape, V shape, and + shape.
