Abstract

A reaction and delivery implement that includes a handle configured for user manipulation, a head having a plurality of agent housing regions, the first agent housing region housing a first agent and the second agent housing region housing a second agent, the first and second agents being different. The head is configured to facilitate both prevention of intermixing of the first and second agents in a storage position as well as reaction of the first and second agents through intermixing in a delivery position so as to produce and apply a third agent to a contacted surface when in the delivery position. The reaction and delivery implement may be an oral care implement such as a toothbrush. The implement may also be motorized and may be used with a wide array of reactions.

First claim

What is claimed is:

1. A brush, comprising:
a handle configured for user manipulation; and
a head extending along a longitudinal axis and having a plurality of housing regions including a first housing region having a first agent and a second housing region having a second agent, the first housing region being a first grouping of cleaning elements having the first agent integrated thereon and being free of the second agent and the second housing region being a second grouping of cleaning elements having the second agent integrated thereon and being free of the first agent;
wherein a subset of the cleaning elements of the first grouping is directly adjacent to a subset of the cleaning elements of the second grouping;
wherein the first and second agents are different; and
wherein the head is configured to prevent intermixing of the first and second agents in a storage mode, and during use of the brush, the head enables intermixing of the first and second agents so as to produce and apply a third agent to a surface.

2. The brush of claim 1 , wherein the first grouping of cleaning elements is located on a distal region of the head and the second grouping of cleaning elements is located on a proximal region of the head, wherein the subset of the cleaning elements of the first grouping are the proximal-most cleaning elements of the first grouping, and wherein the subset of the cleaning elements of the second grouping are the distal-most cleaning elements of the second grouping.

3. The brush of claim 1 , wherein the cleaning elements of the first grouping and the cleaning elements of the second grouping are aligned together in longitudinal columns, each longitudinal column having one or more cleaning elements of the first grouping and one or more cleaning elements of the second grouping.

4. The brush of claim 3 , wherein for each longitudinal column, one of the cleaning elements of the first grouping is directly adjacent to one of the cleaning elements of the second grouping.

5. The brush of claim 1 , wherein the first and second groupings of cleaning elements are arranged in rows extending transversely across the head, and wherein at least one of the rows includes cleaning elements of the first grouping and cleaning elements of the second grouping.

6. The brush of claim 5 , wherein in the at least one of the rows that includes cleaning elements of the first grouping and cleaning elements of the second grouping, the cleaning elements of the second grouping are located between the cleaning elements of the first grouping.

7. The brush of claim 5 , wherein only one of the rows includes cleaning elements of the first and second groupings, the remaining rows including only cleaning elements of the first grouping or only cleaning elements of the second grouping.

8. The brush of claim 1 , wherein the first grouping of cleaning elements are housed on a first tuft plate that is coupled to the head and the second grouping of cleaning elements are housed on a second tuft plate that is coupled to the head.

9. The brush of claim 8 , wherein each of the first and second tuft plates is separately removably coupled to the head.

10. The brush of claim 8 , wherein the first grouping of cleaning elements are arranged in a plurality of concentric rows on the first tuft plate and wherein the second grouping of cleaning elements are arranged in a plurality of concentric rows on the second tuft plate.

11. A motorized brush, comprising:
a handle configured for user manipulation; and
a head extending along a longitudinal axis and having a plurality of agent housing regions including a first moveable tuft plate comprising a plurality of first cleaning elements having a first agent thereon and a second moveable tuft plate comprising a plurality of second cleaning elements having a second agent thereon, the plurality of first cleaning elements being free of the second agent and the plurality of second cleaning elements being free of the first agent, the first and second movable tuft plates being axially spaced apart and moving in opposing direction, the first and second agents being different, wherein the head is configured to facilitate both prevention of intermixing of the first and second agents in a storage position as well as reaction of the first and second agents through intermixing in a delivery position by movement of the first and second moveable tuft plates so as to produce and apply a third agent to a contacted surface when in the delivery position.

12. The motorized brush of claim 11 wherein the first cleaning elements are arranged in a plurality of concentric rows on the first moveable tuft plate and the second cleaning elements are arranged in a plurality of concentric rows on the second moveable tuft plate.

13. The brush of claim 11 wherein the first moveable tuft plate has a first center-point and the second moveable tuft plate has a second center-point, and wherein the first and second center-points are axially spaced apart.

14. A brush, comprising:
a handle configured for user manipulation; and
a head having a plurality of cleaning elements extending therefrom, the plurality of cleaning elements comprising a first grouping of cleaning elements arranged in a first loop and a second grouping of cleaning elements positioned within the first loop;
wherein the first grouping of cleaning elements comprise a first agent thereon and the second grouping of cleaning elements comprise a second agent thereon, the first and second agents being different, the first grouping of cleaning elements being free of the second agent and the second cleaning elements being free of the first agent; and
wherein the head is configured to prevent intermixing of the first and second agents in a storage mode, and during use of the brush, the head enables intermixing of the first and second agents to produce a third agent.

15. The brush of claim 14 further comprising a third grouping of cleaning elements arranged in a second loop that surrounds the first loop, the third grouping of cleaning elements comprising the second agent thereon.

16. The brush of claim 15 wherein the first and second loops are concentric.

17. The brush of claim 14 wherein the first grouping of cleaning elements comprises tufts of bristles that retain the first agent directly thereon and wherein the second grouping of cleaning elements comprises tufts of bristles that retain the second agent directly thereon.
