Abstract
A fluid dispensing toothbrush (100). In one aspect, the toothbrush comprises a body (105) having a reservoir (135) containing an oral care fluid (136) therein, the oral care fluid being delivered to an applicator (132) via capillary action. The toothbrush comprises an actuator (130) for moving either the applicator and/or the reservoir between different positions.
Claims26
A toothbrush having a longitudinal axis comprising:
- a body comprising a handle, a head coupled to a distal end of the handle, and an internal reservoir containing an oral care fluid;
- a channel in the body extending from the reservoir to an opening in an outer surface of the body;
- an applicator comprising a capillary material;
- an actuator operably coupled to the applicator to move the applicator between:
- (1) a protracted position in which a portion of the applicator protrudes from the opening;
- and (2) a retracted position in which the portion of the applicator is retracted into the channel via the opening;
- and
- wherein the applicator is in fluid communication with the oral care fluid within the reservoir in both the protracted position and the retracted position so that the oral care fluid is delivered to the applicator via capillary action.

A toothbrush having a longitudinal axis comprising:
- a body comprising a handle, a head coupled to a distal end of the handle, and an internal cavity;
- a reservoir housing disposed within the internal cavity of the body and containing an oral care fluid;
- an applicator comprising a capillary material affixed to an outer surface of the body;
- a channel in the body extending from the internal cavity to the applicator;
- an actuator operably coupled to the reservoir housing for moving the reservoir housing within the internal cavity between:
- (1) a first position in which the applicator is removed from fluid communication with the oral care fluid within the reservoir housing;
- and (2) a second position in which the applicator is in fluid communication with the oral care fluid within the reservoir housing so that the oral care fluid is delivered to the applicator via capillary action.
