Abstract

A method of sanitizing a toothbrush. The method may include delivering a sanitizing fluid from a reservoir of a toothbrush that comprises a store of the sanitizing fluid to bristle tufts of the toothbrush solely via capillary action, wherein each of the bristle tufts comprises a plurality of bristle filaments so that the sanitizing fluid wicks upwardly along the bristle tufts within spaces between the bristle filaments to sanitize the bristle filaments.

First claim

What is claimed is:

1. A method of sanitizing a toothbrush comprising:
delivering a sanitizing fluid from a reservoir of a toothbrush that comprises a store of the sanitizing fluid to bristle tufts of the toothbrush solely via capillary action, wherein each of the bristle tufts comprises a plurality of bristle filaments so that the sanitizing fluid wicks upwardly along the bristle tufts within spaces between the bristle filaments to sanitize the bristle filaments;
wherein the reservoir of the toothbrush is located in a handle of the toothbrush, at least one capillary member extending from the handle of the toothbrush to the bristle tufts; and
wherein the at least one capillary member comprises a main body and a plurality of fibers extending between the main body and the plurality of bristle filaments.

2. The method according to claim 1 further comprising:
rinsing the bristle tufts with a rinse fluid to remove the sanitizing fluid from the bristle tufts; and
after the rinsing, applying a toothpaste to the bristle tufts of the toothbrush and brushing teeth with the bristle tufts.

3. The method according to claim 2 wherein the rinse fluid is tap water.

4. The method according to claim 2 further comprising, after brushing the teeth with the bristle tufts, allowing the toothbrush to rest idly for a period of time during which the sanitizing fluid is delivered from the reservoir to the bristle tufts solely via capillary action to sanitize the bristle filaments in between toothbrushing sessions.

5. The method according to claim 1 wherein the bristle tufts have distal ends, and wherein the sanitizing fluid wicks upwardly along the bristle tufts towards the distal ends.

6. The method according to claim 1 wherein the bristle filaments are non-hollow and formed from a non-porous material such that the sanitizing fluid cannot pass through or along the bristle filaments individually.

7. The method according to claim 1 wherein the sanitizing fluid is selected from the group consisting of hydrogen peroxide, Sodium bicarbonate, Sodium hypochlorite, Sodium perborate, and Potassium peroxymonosulfate.

8. A method of sanitizing a toothbrush in between toothbrushing sessions, the method comprising:
after a first toothbrushing session, delivering a sanitizing fluid from a reservoir of a toothbrush that comprises a store of the sanitizing fluid to bristle tufts of the toothbrush solely via capillary action to sanitize the bristle tufts;
applying a toothpaste to the bristle tufts of the toothbrush;
conducting a second toothbrushing session with the bristle tufts having the toothpaste thereon; and
after completion of the second toothbrushing session, allowing the toothbrush to rest idly for a period of time during which the sanitizing fluid is delivered from the reservoir to the bristle tufts via capillary action to sanitize the bristle tufts in between toothbrushing sessions;
wherein the sanitizing fluid is delivered from the reservoir of the toothbrush via a capillary member extending between a handle of the toothbrush and the bristle tufts of the toothbrush, the capillary member comprising a main body and a plurality of fibers extending from the main body; and
wherein the plurality of fibers of the capillary member extend between the main body and a proximal end of each of the bristle tufts.

9. The method according to claim 8 further comprising, prior to applying the toothpaste to the bristle tufts of the toothbrush, rinsing the bristle tufts with a rinse fluid to remove the sanitizing fluid from the bristle tufts.

10. The method according to claim 9 wherein the rinse fluid is tap water.

11. The method according to claim 8 wherein each of the bristle tufts comprises a plurality of bristle filaments, and wherein delivering the sanitizing fluid from the reservoir to the bristle tufts comprises wicking the sanitizing fluid upwardly along the bristle tufts within spaces between the bristle filaments.

12. The method according to claim 11 wherein the bristle filaments are non-hollow and formed from a non-porous material such that the sanitizing fluid cannot pass through or along the bristle filaments individually.

13. The method according to claim 8 wherein the sanitizing fluid is selected from the group consisting of hydrogen peroxide, Sodium bicarbonate, Sodium hypochlorite, Sodium perborate, and Potassium peroxymonosulfate.

14. The method according to claim 8 wherein the bristle tufts have distal ends, and wherein the sanitizing fluid wicks upwardly along the bristle tufts to the distal ends.
