Abstract

A hair dye device includes a barrel, wherein the barrel includes a hollow center and a hook extending from one end of the barrel and an absorbent material impregnated with hair dye, wherein the absorbent material is configured to extend beyond the one end of the barrel, wherein a tip of the absorbent material moves toward the hook to provide a loop to capture hair within the loop.

Claims

1. A hair dye device, comprising:

a barrel, wherein the barrel includes a hollow center and a hook extending from one end of the barrel; and

an absorbent material impregnated with hair dye, wherein the absorbent material is configured to extend beyond the one end of the barrel, wherein a tip of an extended absorbent material rests at an apex of the hook to provide a loop to capture hair within the loop, wherein a closed loop is formed when the tip of the absorbent material rests at the apex, wherein a dimension across the absorbent material is less than a dimension across the hook measured at a hook end, and the closed loop includes a space along an inside of the hook between the extended absorbent material and the hook from a start of the hook at the barrel to near the apex of the hook.

2. The hair dye device of claim 1, wherein the absorbent material is configured to retract within the hollow center.

3. The hair dye device of claim 1, wherein the hook is an extension of the barrel.

4. The hair dye device of claim 1, wherein the hook extends from the one end of the barrel and curves from one side of the barrel toward the opposite side, and crosses over the hollow center.

5. The hair dye device of claim 1, wherein the hook extends from the one end of the barrel and curves from one side of the barrel toward the opposite side, and crosses over the barrel center, and the absorbent material extends from the hollow center toward the hook.

6. The hair dye device of claim 1, wherein the hollow center extends in the axial direction.

7. The hair dye device of claim 1, wherein the hook and absorbent material form the loop with a side of the absorbent material impregnated with dye facing the interior of the loop.

8. The hair dye device of claim 1, wherein the hook and absorbent material form a fully closed loop when the absorbent material is touching the hook.

9. The hair dye device of claim 1, wherein the hook and absorbent material form a partly open loop when the absorbent material is not touching the hook.

10. The hair dye device of claim 1, wherein the barrel is on the device exterior, and the absorbent material is on the interior of the barrel.

11. The hair dye device of claim 1, wherein the absorbent material includes fibers, bristles, paper, pulp, animal hairs, felt, or a combination thereof.

12. The hair dye device of claim 1, further comprising a reservoir connected to the absorbent material.

13. A method of making a hair dye device, comprising:

providing a barrel, wherein the barrel includes a hollow center and a hook extending from one end of the barrel;

providing an absorbent material; and

assembling the absorbent material in the hollow center of the barrel, wherein the absorbent material is configured to extend beyond the one end of the barrel, wherein a tip of an extended absorbent material rests at an apex of the hook to provide a loop to capture hair within the loop, wherein a closed loop is formed when the tip of the absorbent material rests at the apex, wherein a dimension across the absorbent material is less than a dimension across the hook measured at a hook end, and the closed loop includes a space along an inside of the hook between the extended absorbent material and the hook from a start of the hook at the barrel to near the apex of the hook.

14. The method of claim 13, further comprising impregnating the absorbent material with a hair dye.

15. The method of claim 14, further comprising replacing a depleted absorbent material with a freshly impregnated absorbent material.

16. The method of claim 14, further comprising filling a hair dye reservoir in the barrel.

17. A method of dying hair, comprising:

providing an absorbent material impregnated with hair dye within a barrel having a hollow center and a hook extending from one end of the barrel, wherein the absorbent material is configured to extend beyond the one end of the barrel; and

moving the absorbent material to rest a tip of the extended absorbent material at an apex of the hook to provide a loop to capture hair within the loop, wherein a closed loop is formed when the tip of the absorbent material rests at the apex, wherein a dimension across the absorbent material is less than a dimension across the hook measured at a hook end, and the closed loop includes a space along an inside of the hook between the extended absorbent material and the hook from a start of the hook at the barrel to near the apex of the hook.

18. The method of claim 17, further comprising moving the barrel with the hair captured in the loop along a length of the hair.

19. The method of claim 17, wherein the hair is captured in the loop and the absorbent material impregnated with hair dye is facing toward the interior of the loop.
