Interdental cleaning device
An interdental cleaning device that delivers an oral care fluid to a cleaning element via capillary action. The invention can be an interdental cleaning device comprising: a housing forming an internal reservoir containing an oral care fluid; an applicator extending from the housing, the applicator comprising a stem and at least one cleaning element extending from the stem; and wherein the stem comprises a capillary material that extends into the reservoir to be in fluid communication with the oral care fluid so that the capillary material of the stem delivers the oral care fluid from the reservoir to the at least one cleaning element via capillary action.
1. An interdental cleaning device comprising:
a housing forming an internal reservoir containing an oral care fluid;
a mass of capillary material disposed in the reservoir and containing at least a portion of the oral care fluid;
an applicator extending from the mass of capillary material, the applicator comprising a stem extending along a longitudinal axis and a plurality of cleaning elements extending from the stem in opposing directions transverse to the longitudinal axis, and wherein an entirety of the stem that extends beyond a top surface of the housing to a distal end of the stem is exposed; and
wherein the stem comprises a capillary material that extends into the reservoir to be in fluid communication with the oral care fluid, and wherein the plurality of cleaning elements are integrally formed with the stem and constructed of the capillary material so that the capillary material of the stem delivers the oral care fluid from the reservoir to the plurality of cleaning elements via capillary action.
2. The interdental cleaning device according to claim 1 wherein the housing is formed of a material that fluidicly contains the oral care fluid within the reservoir.
3. The interdental cleaning device according to claim 1 wherein the mass of capillary material fills a substantial entirety of the reservoir.
4. The interdental cleaning device according to claim 1 wherein the mass of capillary material has a first pore size and the stem has a second pore size, the first pore size being greater than the second pore size.
5. The interdental cleaning device according to claim 1 wherein the capillary material of the stem is integrally formed with the mass of capillary material disposed in the reservoir.
6. The interdental cleaning device according to claim 1 wherein the capillary material of the stem and the mass of capillary material disposed in the reservoir are a porous material, a fibrous material, or a material comprising one or more capillary channels.
7. The interdental cleaning device according to claim 6 wherein the capillary material of the stem and the mass of capillary material disposed in the reservoir are selected from the group consisting of polyethylene, polypropylene, cellulose, wool, polyester, collagen, nylon and combinations thereof.
8. The interdental cleaning device according to claim 1 wherein the applicator is detachably coupled to the housing.
9. The interdental cleaning device according to claim 8 further comprising the stem comprising a plug portion formed of the capillary material, the mass of capillary material disposed in the reservoir comprising a socket, the plug portion disposed within the socket so that the oral care fluid contained in the mass of capillary material can flow into the plug portion of the stem via capillary action.
10. The interdental cleaning device according to claim 9 wherein the applicator comprises a closure plate through which the stem extends, the plug portion of the stem located on a first side of the closure plate and the plurality of cleaning elements disposed on a second side of the closure plate opposite the first side, the closure plate closing an opening in the housing when the applicator is detachably coupled to the housing, and the closure plate constructed of a material that fluidicly contains the oral care fluid within the reservoir.
11. The interdental cleaning device according to claim 8 wherein the applicator comprises a closure plate, the stem of the applicator extending through the closure plate, and wherein the closure plate closes an opening in the housing when the applicator is detachably coupled to the housing.
12. The interdental cleaning device according to claim 1 wherein the stem and the plurality of cleaning elements are constructed entirely of the capillary material.
13. The interdental cleaning device according to claim 1 wherein the stem comprises one or more capillary channels for flowing the oral care fluid from the reservoir to the plurality of cleaning elements via capillary action.
14. The interdental cleaning device according to claim 13 wherein the plurality of cleaning elements comprises a capillary channel in fluid communication with the one or more capillary channels of the stem.
15. The interdental cleaning device according to claim 1 wherein the stem comprises a core element disposed within the capillary material of the stem.
16. The interdental cleaning device according to claim 15 further comprising bristles secured to the core element and protruding from the capillary material.
17. The interdental cleaning device according to claim 15 wherein the core element is encased in the capillary material of the stem.
18. The interdental cleaning device according to claim 15 wherein the capillary material of the stem wraps around or is intertwined with the core element.
19. The interdental cleaning device according to claim 1 further comprising a cap that is detachably coupled to the housing, the cap enclosing the applicator when detachably coupled to the housing.
