Abstract

A tube-shaped assembly, a tube-shaped part and an associated method of manufacturing the same are provided. In regards to a method, a glass or plastic tube is provided that has a maskant positioned upon an interior region of the tube to define a window. The method also includes coating an interior surface of the tube with a tinted anti-splinter material having a dye or pigment mixed therein. The method also includes curing the tinted anti-splinter material and removing the maskant such that the interior region is free of the tinted anti-splinter material. A tube-shaped part is also provided that includes a glass or plastic tube and a maskant positioned upon an interior region of the tube to define a window. The tube-shaped part also includes a tinted anti-splinter material having a dye or pigment mixed therein.

Claims

1. An apparatus comprising:

a glass or plastic seamless tube;

a tinted antisplinter material having a colorant mixed therein that coats an interior surface of the tube, wherein the tinted antisplinter material positioned upon an interior region of the tube to define a window;

an optical clear adhesive on at least a portion of the window; and

an internal electronic component within the tube and secured to the optical clear adhesive in at least partial alignment with the window.

2. An apparatus according to claim 1 wherein the tinted antisplinter material has a dye or pigment mixed therein.

3. An apparatus according to claim 1 wherein the tube extends along a length between opposed longitudinal ends, wherein the tube is closed along its length and seamless along its length.

4. An apparatus according to claim 3 wherein the opposed ends are open.

5. An apparatus according to claim 1 wherein the optical clear adhesive extends beyond the window.

6. An apparatus according to claim 5 wherein edges of the optical clear adhesive overlap with the tinted antisplinter material.

7. An apparatus according to claim 1 wherein the internal electronic component comprises at least one of a display or a touch stack.

8. An apparatus according to claim 3, wherein the glass or plastic tube comprises opposed planar surfaces extending along the length and opposing arcuate side surfaces there between.

9. An apparatus according to claim 3, wherein the tube comprises an extruded tube that is cut to length.

10. An apparatus according to claim 3, wherein the tube comprises a polished exterior surface.

11. An apparatus according to claim 1, wherein the tube is tempered.

12. An apparatus according to claim 1, wherein the tube is atomic layer deposit strengthened.

13. An apparatus according to claim 1, wherein the anti-splinter material comprises a thickness of between about 0.01 millimeters and 0.20 millimeters.

14. An apparatus according to claim 1, wherein the anti-splinter material is an ultraviolet-cured anti-splinter material.

15. An apparatus according to claim 1, wherein the anti-splinter material comprises a resin and a catalyst.
