Abstract

A toothbrush comprising a body comprising a handle portion, a head portion and a longitudinal axis; a plurality of tooth cleaning elements extending from the head portion; a depression formed in an outer surface of the handle portion of the body, the depression comprising a floor; a power source disposed within the body; an electromagnetic radiation (EMR) source disposed within the handle portion and operably coupled to the power source, the EMR source configured to emit EMR from the floor of the depression; and a cover coupled to the handle portion so as to be alterable between: (1) a storage state in which the depression is enclosed by the cover; and (2) a use state in which the floor of the depression is exposed.

First claim

What is claimed is:

1. A toothbrush comprising:
a body comprising a handle portion, a head portion and a longitudinal axis;
a plurality of tooth cleaning elements extending from the head portion;
a depression formed in an outer surface of the handle portion of the body, the depression comprising a floor;
a power source disposed within the body;
an electromagnetic radiation (EMR) source disposed within the handle portion and operably coupled to the power source, the EMR source configured to emit EMR from the floor of the depression; and
a cover coupled to the handle portion so as to be alterable between: (1) a storage state in which the depression is enclosed by the cover; and (2) a use state in which the floor of the depression is exposed.

2. The toothbrush according to claim 1 wherein the depression is longitudinally elongated.

3. The toothbrush according to claim 1 wherein the floor of the depression is concave.

4. The toothbrush according to claim 1 wherein an outer surface of the handle portion is substantially flush with an outer surface of the cover when the cover is in the storage state.

5. The toothbrush according to claim 1 further comprising a bite guard protruding from the floor of the depression, the EMR source configured to emit EMR from the floor of the depression adjacent the bite guard.

6. The toothbrush according to claim 5 wherein the EMR source comprises a first EMR source portion and a second EMR source portion, the bite guard located between the first and second EMR source portions.

7. The toothbrush according to claim 1 wherein the depression is located in a proximal section of the handle portion, the head portion coupled to a distal end of the handle portion.

8. The toothbrush according to claim 1 further comprising a store of oral care material, wherein the oral care material has an efficacy that is increased or activated by EMR generated by the EMR source.

9. The toothbrush according to claim 8 wherein the store of oral care material is disposed within an internal cavity of the body, the toothbrush further comprising an applicator comprising a dispensing orifice coupled to the body.

10. The toothbrush according to claim 9 wherein the applicator protrudes from a proximal end of the handle portion.

11. The toothbrush according to claim 8 wherein the store of oral care material is disposed in a dispenser that is coupled to the body, the dispenser comprising an applicator comprising a dispensing orifice.

12. The toothbrush according to claim 8 wherein the store of oral care material is disposed in the cover, the cover comprising an applicator comprising a dispensing orifice.

13. The toothbrush according to claim 1 further comprising a switch, the switch operably coupled to the EMR source and the power source to turn the EMR source off and on.

14. The toothbrush according to claim 13 wherein the switch is inaccessible to a user when the cover is in the storage state.

15. The toothbrush according to claim 13 wherein the switch is automatically maintained or actuated to an open state when the cover is in the storage state.
