Abstract

A dispenser ( 800 ) for dispensing oral care materials comprising: a housing ( 810 ) having a separator wall ( 805 ) forming a first reservoir chamber ( 830 ) containing a first oral care material ( 831 ) and a second reservoir chamber ( 840 ) containing a second oral care material ( 841 ) within the housing ( 810 ); a first nozzle ( 860 ) for dispensing the first oral care material ( 831 ) from the first reservoir chamber ( 830 ) and a second nozzle ( 865 ) for dispensing the second oral care material ( 841 ) from the second reservoir chamber ( 840 ), the first and second nozzles ( 860, 865 ) located on opposite ends of the dispenser ( 800 ); and wherein the first reservoir chamber ( 830 ) circumferentially surrounds the second reservoir chamber ( 840 ) about a longitudinal axis of the dispenser ( 800 ).

First claim

What is claimed is:

1. A dispenser comprising:
a housing having a separator wall forming a first reservoir chamber containing a first oral care material and a second reservoir chamber containing a second oral care material within the housing;
a first nozzle for dispensing the first oral care material from the first reservoir chamber and a second nozzle for dispensing the second oral care material from the second reservoir chamber, the first and second nozzles located on opposite ends of the dispenser;
a first dispensing chamber that is in fluid communication with the first reservoir chamber, the first nozzle extending from the first dispensing chamber;
a second dispensing chamber that is in fluid communication with the second reservoir chamber, the second nozzle extending from the second dispensing chamber; and
wherein the first reservoir chamber circumferentially surrounds the second reservoir chamber about a longitudinal axis of the dispenser.

2. The dispenser according to claim 1 wherein the separator wall is a tubular wall having a closed end and an open end, the open end in fluid communication with the second nozzle.

3. The dispenser according to claim 2 wherein the housing and the separator wall are compressible.

4. The dispenser according to claim 1 further comprising a first cap removably coupled to the dispenser to seal the first nozzle and a second cap removably coupled to the dispenser to seal the second nozzle.

5. The dispenser of claim 4 , wherein the second oral care material is dispensed by compressing the housing while the first cap is maintained on the first nozzle and the second cap has been removed from the second nozzle.

6. The dispenser of claim 1 , wherein the separator wall comprises a cylinder having a substantially constant cross-section.

7. The dispenser of claim 1 , wherein the housing comprises a second cylinder having a substantially constant cross-section.

8. The dispenser of claim 1 , wherein the first dispensing chamber is separated from the first reservoir chamber by a first transverse wall, a first opening being formed in the first transverse wall to enable the first oral care material to flow from the first reservoir chamber into the first dispensing chamber, and wherein the second dispensing chamber is separated from the first reservoir chamber by a second transverse wall, a second opening being formed in the second transverse wall to enable the second oral care material to flow from the second reservoir chamber into the second dispensing chamber.

9. The dispenser of claim 1 , further comprising one or more air ports that provide a one-way passage from the external environment into the second reservoir chamber.

10. The dispenser of claim 9 , wherein the one or more air ports providing a one-way passage into the second reservoir chamber are formed in a wall of the second dispensing chamber.

11. A dispenser comprising:
a housing having a separator wall forming a first reservoir chamber containing a first oral care material and a second reservoir chamber containing a second oral care material within the housing;
a first nozzle for dispensing the first oral care material from the first reservoir chamber and a second nozzle for dispensing the second oral care material from the second reservoir chamber, the first and second nozzles located on opposite ends of the dispenser; and
one or more air ports that provide a one-way passage from the external environment into the first reservoir chamber.

12. An oral care system comprising:
an oral care implement; and
a dispenser detachably coupled to the oral care implement, the dispenser comprising:
a housing having a separator wall forming a first reservoir chamber containing a first oral care material and a second reservoir chamber containing a second oral care material within the housing;
a first nozzle for dispensing the first oral care material from the first reservoir chamber and a second nozzle for dispensing the second oral care material from the second reservoir chamber, the first and second nozzles located on opposite ends of the dispenser; and
wherein the first reservoir chamber circumferentially surrounds the second reservoir chamber about a longitudinal axis of the dispenser.

13. The oral care system according to claim 12 , wherein the oral care implement is a toothbrush.

14. The oral care system according to claim 12 , wherein the dispenser is or can be secured to the oral care implement in an assembled or storage state in which the dispenser forms a portion of a handle of the oral care implement.
