Abstract

An oral care implement comprises a head with a plurality of cleaning elements, and a light source incorporated into or adjacent the head. The light source is incorporated prior to the attachment of the cleaning elements. For ease of manufacturing and a cost-effective assembly. The cleaning elements are preferably preformed and attached to the head after the incorporation of the light source so that the provision of the light source does not require any post-processing that might impair the integrity of the head or cleaning elements.

Claims (31)

1. A light-emitting oral care implement comprising:

a) a head and a handle, the head further comprising a socket;

b) a light source in or adjacent the head, the light source being removable and replaceable through an access panel on a rear surface of the head;

c) a pre-formed plurality of cleaning elements secured to a plate that is positioned over the socket;

d) a soft tissue cleaner on a side of the head opposite the cleaning elements;

wherein the light source is defined between the cleaning elements and the socket; and

wherein light from the light source transmits through the plate and through the soft tissue cleaner.

2. The implement of claim 1 , the handle further comprising a power source for powering the light source.

3. The implement of claim 1 , wherein the head further comprises a chamber, the plate positioned over the chamber, and wherein the socket is formed into a floor of the chamber, the light source being seated in the socket.

4. The implement of claim 1 , further comprising at least one opening defined in the plate, the light from the light source transmitting through the opening,

5. The implement of claim 1 , further comprising, a plurality of light passages formed in the plurality of cleaning elements.

6. The implement of claim 5 , the head being formed of a light transmissive material such that light is transmitted through the head in addition to through the plurality of light passages.

7. The implement of claim 1 , the head being formed of a light transmissive material for transmitting light from the light source.

8. A light-emitting oral care implement comprising:

a) a head and a handle, the head further comprising a socket;

b) a light source in or adjacent the head, the light source being, removable through a slot in an edge of the head, the slot forming a passageway from an external environment to the socket;

c) a pre-formed plurality of cleaning elements secured over the socket; and

wherein the light source is defined between the cleaning elements and the socket.

9. The implement of claim 8 , where the slot is in an upper edge of the head.

10. The implement of claim 8 , where the slot is in a side edge of the head.

11. The implement of claim 1 , the light source being a light-emitting diode (LED).

12. The implement of claim 11 , wherein the LED is a surface mounted device LED (SMD LED).

13. The implement of claim 1 , the light source residing on a printed control board (PCB) in the head.

14. The implement of claim 13 , the light source being a LED.

15. The implement of claim 14 , the PCB being removable through the head.

16. The implement of claim 15 , the PCB being removable through a rear surface of the head.

17. The implement of claim 1 , wherein the light source is in the handle and the head emits light to a user's oral cavity during use of the oral care implement.

18. The implement of claim 1 , wherein the plate is welded to the head.

19. The implement of claim 1 , the soft tissue cleaner comprising, at least one light passage.

20. The implement of claim 1 , the soft tissue cleaner conveying at least one benefit in addition to cleaning.

21. The implement of claim 1 , the soft tissue cleaner being formed of a light transmissive material.
