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 ### Claim 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 having protruding portions and recessed portions forming a pattern visible on an outer surface of the injection-molded product; and a coupling structure formed on one or more protruding portions of the pattern structure and extending substantially perpendicular from an adjoining surface of the pattern structure, said coupling structure extending along said one or more protruding portions of the adjoining surface of the pattern structure without covering any recessed portions of the pattern structure, wherein the coupling structure having a width and a length that is less than a width and a length of the adjoining surface of the pattern structure, and wherein the coupling structure is formed within an area defined by the adjoining surface of the pattern structure along the inner surface of the injection molded product to block visibility of the coupling structure from the outer surface of the injection-molded product. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 1) The injection-molded product of claim 1, wherein the pattern structure is in a shape of a band in which the protruding portions and the recessed portions are alternately formed in succession. ### Claim 4 (depends on 1) The injection-molded product of claim 1, wherein the pattern structure is formed such that the protruding portions and the recessed portions are alternately formed on the entire inner surface of the injection-molded product. ### Claim 5 (depends on 1) The injection-molded product of claim 1, wherein the pattern structure is formed of lattice patterns which consecutively protrude at least adjacent to an edge of the inner surface of the injection-molded product. ### Claim 6 (depends on 1) The injection-molded product of claim 1, wherein the pattern structure is in a shape in which the coupling structure is consecutively formed. ### Claim 7 (depends on 1) The injection-molded product of claim 1, wherein each of the recesses has a predetermined shape which is one of an O shape, a zigzag shape, a V shape, and a + shape. ### Claim 8 A device for enclosing components of a portable electronic device, comprising: a first case and a second case, wherein each of the first and second cases includes: a pattern structure formed on an inner surface of the respective case, and having protruding portions and recessed portions forming a pattern visible on an outer surface of the respective case; and a coupling structure formed on one or more protruding portions of the pattern structure and extending substantially perpendicular from an adjoining surface of the pattern structure, said coupling structure extending along said one or more protruding portions of the adjoining surface of the pattern structure via an injection molding process without covering any recessed portions of the pattern structure, wherein the coupling structure having a width and a length that is less than a width and a length of the adjoining surface of the pattern structure, and wherein the coupling structure is formed within an area defined by adjoining surface of the pattern structure along the inner surface of the injection molded product to block visibility of, the coupling structure from the outer surface of the injection-molded product; and wherein the first case and the second case interlocks to each other via the respective coupling structures. ### Claim 9 (depends on 8) The device of claim 8, wherein the pattern structure is in a shape of a band in which the protruding portions and the recessed portions are alternately formed in succession. ### Claim 10 (depends on 8) The device of claim 8, wherein the pattern structure is formed such that the protruding portions and the recessed portions are alternately formed on the entire inner surface therein. ### Claim 11 (depends on 8) The device of claim 8, wherein the pattern structure is formed of lattice patterns which consecutively protrude at least adjacent to an edge of the inner surface therein. ### Claim 12 (depends on 8) The device of claim 8, wherein the pattern structure is in a shape in which the coupling structure is consecutively formed. ### Claim 13 (depends on 8) The device of claim 8, wherein each of the recesses has a predetermined shape which is one of an O shape, a zigzag shape, a V shape, and a + shape.
