Abstract

The invention relates to coating or otherwise modifying or changing a surface characteristic, including a surface characteristic of a device for administering an injectable product, wherein the device includes a casing made of multiple casing parts, wherein at least one external surface of at least one of the casing parts is completely or partially provided with one or more surface-refining coatings. The coating may be applied to the casing part after or while the casing part is shaped, and the coating may comprise various materials which may be arranged alongside each other, on top of each other or may be mixed.

Claims

1. A device for administering an injectable product, comprising:

a casing comprising multiple casing parts, at least one of the casing parts including a surface;

a coating, wherein the coating is applied to the surface of the at least one casing part, after or while the casing part is shaped;

wherein

the coating changes a surface characteristic of the surface to which it is applied.

2. The device of claim 1, wherein said changes in surface characteristics comprise at least one of improved individualism or distinctiveness of the device, improved protection and handling of the device, and increased monitoring options when using the device.

3. The device of claim 1, wherein the coating comprises a paint.

4. The device of claim 2, wherein the paint is a fluorescent paint.

5. The device of claim 2, wherein the paint is a metallic dye.

6. The device of claim 2, wherein the coating comprises a material that changes color with a change in temperature.

7. The device of claim 6, wherein the change in color is permanent.

8. The device of claim 2, wherein the coating comprises a material having a higher friction coefficient than a base material of the casing part to which the coating is applied.

9. The device of claim 8, wherein the coating is applied over at least one impact edge of at least one casing part.

10. The device of claim 2, wherein the coating comprises a thermally insulating material.

11. The device of claim 10, wherein the coating comprises a reflective material.

12. The device of claim 10, wherein the coating comprises a fibrous material.

13. The device of claim 2, wherein the coating comprises a material having a lower thermal conductivity coefficient than a material of the casing part to which it is applied.

14. The device of claim 2, wherein the coating comprises a material provided with an odor additive.

15. The device of claim 2, wherein the coating comprises a material provided with a tactile additive.

16. The device of claim 1, wherein the coating comprises a material that forms a holographic representation.

17. The device of claim 1, wherein the surface is completely coated.

18. The device of claim 1, wherein the surface is partially coated.

19. The device of claim 1, wherein a plurality of casing parts are provided with coatings on exterior surfaces thereof and wherein the coatings on the different casing parts are different.

20. The device of claim 1, wherein a first casing part is provided with a coating comprising a thermally insulating material and a second casing part is provided with a coating that changes color with temperature.

21. The device of claim 1, wherein the coating comprises a prefabricated film.

22. The device of claim 1, wherein the coated casing part is arranged, as an additional part, on a functional casing.

23. The device of claim 1, wherein the coating is applied to the casing part by spray-painting, immersion-painting, adhesion, printing, vacuum evaporation, thermo-transfer methods, in-molding methods or airbrush methods.

24. The device of claim 1, wherein the device is an injection apparatus.

25. The device of claim 1, wherein the device is an infusion apparatus.
