Abstract

A reaction and delivery implement (100) that includes a handle (103) configured for user manipulation, a head (102) having a plurality of agent housing regions (120,130), the first agent housing region (120) housing a first agent and the second agent housing region (130) housing a second agent, the first and second agents being different is described. 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.

Claims5

Dependent claims

A toothbrush, comprising:

a handle configured for user manipulation;
a head having a front surface and containing a plurality of cleaning elements extending from the front surface;
a first containment structure located on the front surface of the head for retaining a first agent, and a second containment structure located on the front surface of the head for retaining a second agent, the first and second agents being different, the first and second containment structures positioned on the front surface of the head as abutted and adjacent structures;
a removable barrier positioned on the front surface of the head that separates the first and second containment structures to prevent intermixing of the first and second agents that are housed on opposing sides of the removable barrier in a storage mode;
and
wherein in a delivery mode, the barrier is removed to enable intermixing of the first and second agents so as to produce and apply a third agent to a surface.
