Abstract

An oral care kit comprising an oral care implement and a dispenser. In one aspect, the invention can be an oral care kit comprising at least one toothbrush and a dispenser. The dispenser ( 300 ) comprises a housing ( 309 ) having an internal chamber ( 321 ) containing a plurality of capsules ( 310 ) containing an oral care material; a dispensing conduit ( 322 ) extending from the internal chamber to an exterior of the dispenser; a valve ( 325 ) positioned in the dispensing conduit and biased into a sealed state that prevents moisture from entering the internal chamber; and a dispensing subassembly ( 302, 315, 316, 317 ) configured to dispense one of the capsules from the internal chamber through the valve. The valve is forced into an open state that allows the one capsule to pass therethrough when the one capsule is subjected to a dispensing force imparted by the dispensing subassembly and automatically returns to the sealed state after the one capsule passes therethrough.

First claim

What is claimed is:

1. An oral care dispenser comprising:
a housing haying an internal chamber containing a plurality of capsules containing an oral care material;
a dispensing conduit extending from the internal chamber to an exterior of the dispenser;
a valve positioned in the dispensing conduit, the valve biased into a sealed state that prevents moisture from entering the internal chamber through the dispensing conduit; and
a dispensing subassembly configured to dispense one of the plurality of capsules at a time from the internal chamber through the valve, the valve being forced into an open state that allows the one capsule to pass therethrough when the one capsule is subjected to a dispensing force imparted by the dispensing subassembly, the valve automatically returning to the sealed state after the one capsule passes through the valve;
wherein the dispensing subassembly comprises an actuator and a drive mechanism that imparts the dispensing force onto the one capsule when the actuator is activated by a user; and
wherein the dispensing subassembly further comprises a first resilient member that imparts a loading force onto the plurality of capsules that biases the one capsule into a loading zone of the dispensing conduit.

2. The oral care dispenser according to claim 1 wherein the capsules comprise a moisture degradable shell containing a fluidic oral care material therein.

3. The oral care dispenser according to claim 1 wherein the capsules are substantially spherical beads.

4. The oral care dispenser according to claim 1 wherein the dispensing subassembly further comprises a second resilient member that biases the actuator and drive member into a non-activated state in which the plurality of capsules are prevented from entering the dispensing conduit from the internal chamber.

5. The oral care dispenser according to claim 1 wherein the internal chamber is an elongated passageway in which the plurality of capsules are arranged in single file.

6. The oral care dispenser according to claim 1 wherein the internal chamber is an elongated passageway in which the plurality of capsules are arranged in single file.

7. The oral care dispenser according to claim 6 wherein the plurality of capsules comprise at least a first type of capsules comprising a first oral care material and a second type of capsules comprising a second oral care material, the first oral care material being different than the second oral care material, and the plurality of capsules arranged in the single file so that the first and second types of capsules are in an alternating order.

8. The oral care dispenser according to claim 1 wherein the valve is formed of an elastomeric material.

9. The oral care dispenser according to claim 8 wherein the valve is a duck-billed valve.

10. An oral care kit comprising:
at least one toothbrush; and
a dispenser comprising:
a housing having an internal chamber containing a plurality of capsules containing an oral care material;
a dispensing conduit extending from the internal chamber to an exterior of the dispenser;
a valve positioned in the dispensing conduit, the valve biased into a sealed state that prevents moisture from entering the internal chamber through the dispensing conduit;
a dispensing subassembly configured to dispense one of the plurality of capsules at a time from the internal chamber through the valve, the valve being forced into an open state that allows the one capsule to pass therethrough when the one capsule is subjected to a dispensing force imparted by the dispensing subassembly, the valve automatically returning to the sealed state after the one capsule passes through the valve;

wherein the dispensing subassembly comprises an actuator and a drive mechanism that imparts the dispensing force onto the one capsule when the actuator is activated by a user; and
wherein the dispensing subassembly further comprises a first resilient member that imparts a loading force onto the plurality of capsules that biases the one capsule into a loading zone of the dispensing conduit.

11. The oral care kit according to claim 10 wherein the dispensing subassembly further comprises a second resilient member that biases the actuator and drive mechanism into a non-activated state in which the plurality of capsules are prevented from entering the dispensing conduit from the internal chamber.

12. The oral care kit according to claim 10 wherein the internal chamber is an elongated passageway in which the plurality of capsules are arranged in single file.

13. The oral care kit according to claim 12 wherein the valve is a duck-billed valve.

14. The oral care kit according to claim 10 wherein the valve is formed of an elastomeric material.

15. The oral care kit according to claim 10 wherein the toothbrush comprises a handle and a head, the head having a depression in which the one capsule can nest.

16. The oral care kit according to claim 15 wherein the dispenser further comprises a nozzle that is sized and shaped to be inserted into the depression of the toothbrush.

17. The oral care kit according to claim 15 wherein the toothbrush comprises a means for retaining the one capsule within the depression, and wherein the dispensing force is equal to or greater than a force required to operably insert the one capsule into the retaining means.

18. The oral care kit according to claim 15 wherein the depression is formed into a cleaning element field of the head of the toothbrush.

19. The oral care kit according to claim 10 wherein the capsules comprise a moisture degradable shell containing a fluidic oral care material therein.

20. The oral care kit according to claim 10 further comprising a plurality of the toothbrushes.

21. The oral care kit according to claim 10 wherein the toothbrush and the dispenser are located within a common primary package.

22. The oral care kit according to claim 10 wherein the toothbrush and the dispenser are separate components.

23. The oral care kit according to claim 10 wherein the housing comprises a window for viewing contents of the internal chamber.

24. An oral care kit comprising:
at least one toothbrush; and
a dispenser comprising:
a housing having an internal chamber containing a plurality of capsules containing an oral care material;
a dispensing conduit extending from the internal chamber to an exterior of the dispenser;
a valve positioned in the dispensing conduit, the valve biased into a sealed state that prevents moisture from entering the internal chamber through the dispensing conduit;
a dispensing subassembly configured to dispense one of the plurality of capsules at a time from the internal chamber through the valve, the valve being forced into an open state that allows the one capsule to pass therethrough when the one capsule is subjected to a dispensing force imparted by the dispensing subassembly, the valve automatically returning to the sealed state after the one capsule passes through the valve;

wherein the plurality of capsules comprise a first type of capsules comprising a first oral care material and a second type of capsules comprising a second oral care material, the first oral care material being different than the second oral care material.

25. A method of applying an oral care material to an oral surface comprising:
