Abstract
An oral care implement that delivers a fluid from a reservoir to an applicator by capillary action. The oral care implement may include a head and a handle, the head having tooth cleaning elements extending therefrom. There may also be a reservoir storing a fluid and an applicator on the head. Finally, a delivery member may extend from the reservoir to the applicator. The delivery member may include a capillary tube that draws the fluid from the reservoir to the applicator by capillary action.
Claims15
An oral care implement comprising:
- a head and a handle, the head having at least one tooth cleaning element extending from a front surface of the head;
- a reservoir storing a fluid;
- an applicator in or on the head;
- and
- a delivery member extending from the reservoir to the applicator, the delivery member comprising a capillary tube that draws the fluid from the reservoir to the applicator solely by capillary action;
- wherein at least a portion of the applicator is located within an opening formed in a rear surface of the head such that a perimeter of the rear surface of the head surrounds the applicator, wherein an outer surface of the applicator is flush with an outer surface of the head.
An oral care implement comprising:
- a head and a handle, the head having a front surface and an opposing rear surface, a plurality of tooth cleaning elements extending from the front surface and the rear surface being free of tooth cleaning elements;
- a reservoir storing a fluid;
- an applicator in or on the rear surface of the head, the applicator formed from a porous or fibrous material;
- and
- an opening fluidly connecting the fluid in the reservoir with the applicator so that the fluid can flow from the reservoir to the applicator;
- wherein the applicator is at least partially located within an opening in the rear surface of the head.
An oral care implement comprising:
- a head and a handle, the head having a front surface and a rear surface, at least one tooth cleaning element extending from the front surface of the head, the rear surface being free of tooth cleaning elements;
- a reservoir storing a fluid;
- an outlet on the rear surface of the head;
- and
- a delivery member extending from the reservoir to the outlet, the delivery member comprising a capillary tube that draws the fluid from the reservoir to the outlet by capillary action.
