Abstract

A stylus pen having a plurality of writing tips for writing on a plurality of dissimilar public surfaces, an ink tip configured for dispensing ink while writing on paper, a resistive stylus tip configured for writing on an electronic pad or use on a pin pad and a capacitive stylus tip for writing on a touch screen, all three tips in one stylus pen, for use by an individual, replacing a public pen, a public resistive stylus and eliminating touching a public touch screen with a finger. In one embodiment, each tip has an overcap with an antimicrobial sponge disposed therein, the sponge sanitizing the writing tip when not in use. Stylus pen housing is composed from antimicrobial material such as copper that is sanitary when the stylus pen is in use. An LED (light-emitting diode) light emitting UV light is provided on one overcap.

Claims

1. A stylus pen, for writing on a plurality of dissimilar surfaces, comprising:

a housing having a middle portion, said middle portion having a pair of ends with a writing tip on each end, a first end having an ink tip operative for writing with ink and a second end having a resistive stylus tip operative for writing on an electronic pad, the resistive stylus tip operative for use on a pin pad, the housing having a pair of overcaps, each overcap having a closed end and an open end, the open end operative for covering the ends of the middle portion, a first overcap having a capacitive stylus tip on said closed end, the capacitive stylus tip operative for writing on a touch screen; and

an antimicrobial coating on the middle portion and overcaps, the coating providing a sanitary surface when grasping the stylus pen.

2. The stylus pen as described in claim 1, wherein the coating has an antimicrobial undercoat and an antimicrobial topcoat.

3. The stylus pen as described in claim 2, wherein the antimicrobial undercoat contains a phenoxy phenol.

4. The stylus pen as described in claim 3, wherein the antimicrobial topcoat contains zinc and titanium dioxide.

5. The stylus pen as described in claim 1, wherein the housing is composed of an antimicrobial material, the housing providing a sanitary surface for grasping when writing.

6. The stylus pen as described in claim 5 wherein the antimicrobial material is selected from the group consisting of copper, brass and bronze.

7. The stylus pen as described in claim 6, wherein a second overcap has a protrusion with a bore operative for attaching said overcap through said bore.

8. The stylus pen as described in claim 7, wherein the middle portion has a supply of ink therein for dispensing through the ink tip.

9. The stylus pen as described in claim 8, wherein the each overcap has an antimicrobial sponge disposed in each overcap interior, the antimicrobial sponges contacting the writing tips on the ends of the middle portion when said overcap engages said writing tips, said sponges sanitizing said writing tips when not in use.

10. A stylus pen, for writing on a plurality of dissimilar surfaces, comprising:

a middle portion having a pair of ends with a writing tip on each end, a first end having an ink tip operative for dispensing ink while writing and a second end having a resistive stylus tip operative for writing on an electronic pad, the resistive tip operative for use on a pin pad, said middle portion formed from an antimicrobial material;

a capacitive stylus tip operative for writing on a touch screen;

a plurality of overcaps operative for covering the ends of the tips, each overcap having a closed end and an open end, the open end operative for accessing the cap interior, a first cap having said capacitive stylus on said closed end, said overcaps formed from the antimicrobial material; and

an antimicrobial coating on the middle portion and overcaps, the coating having an antimicrobial undercoat and an antimicrobial topcoat, the coating providing a sanitary surface when grasping the stylus pen.

11. The stylus pen as described in claim 10, wherein the antimicrobial undercoat contains a phenoxy phenol.

12. The stylus pen as described in claim 11, wherein the antimicrobial topcoat contains zinc and titanium dioxide.

13. The stylus pen as described in claim 12, wherein the antimicrobial material is selected from the group consisting of copper, brass and bronze.

14. The stylus pen as described in claim 13, wherein the second overcap has a light-emitting diode (LED) light on the closed end, the LED light emitting sanitizing ultraviolet light when the LED is activated.

15. The stylus pen as described in claim 14, wherein the middle portion has a supply of ink therein for dispensing through the ink tip.

16. A method of making a stylus pen, comprising:

coupling an ink tip to a first end of a middle portion of a stylus pen and coupling a resistive stylus tip to a second end of said middle portion;

providing a plurality of overcaps operative for covering the ends of the middle portion, each overcap having a closed end and an open end, the open end operative for covering the ends of the middle portion;

coupling a capacitive stylus to said closed end of a first overcap; and

coating the middle portion and overcaps with an antimicrobial undercoat and an antimicrobial topcoat providing a sanitary surface for grasping when writing.

17. The method as described in claim 16, wherein the step of coupling an ink tip and a resistive stylus tip to the middle portion is proceeded by the step of forming the middle portion from an antimicrobial material.

18. The method as described in claim 17, wherein the step of providing a plurality of overcaps includes the step of forming the overcaps from the antimicrobial material.

19. The method as described in claim 18, wherein the antimicrobial material is selected from the group consisting of copper, brass and bronze.

20. The method as described in claim 19, wherein the antimicrobial material is further coated with an antimicrobial coating.
