Abstract

An oral care dispenser and oral care system incorporating the system that includes a resilient applicator that optimizes application of the subject fluid to the desired oral surfaces. In one embodiment, the invention is a dispenser comprising a housing having an internal reservoir containing the fluid. The resilient applicator is coupled to the housing and comprises a dispensing orifice. The resilient applicator comprises a working surface that is oriented at an oblique angle to a longitudinal axis of the housing and is defined by a polygonal perimeter edge, the polygonal perimeter edge comprising a plurality of apex portions and a plurality of side portions, wherein one of the plurality of side portions forms a distal most-portion of the resilient applicator.

First claim

What is claimed is:

1. An oral care kit comprising:
a toothbrush; and
a dispenser comprising:
a housing having an internal reservoir containing fluid, the housing extending from a proximal end to a distal end along a longitudinal axis;
a resilient applicator coupled to the distal end of the housing, the resilient applicator comprising:
a dispensing orifice for dispensing the fluid from the reservoir;
a working surface that is oriented at an oblique angle to the longitudinal axis of the housing and defined by a polygonal perimeter edge;
a main body portion having the working surface and a bottom surface, the dispensing orifice forming a fluid passageway from the bottom surface to the working surface; and

a removable cap coupled to the housing and enclosing the resilient applicator, the removable cap comprising an axial plug that extends through and seals the dispensing orifice of the resilient applicator;
wherein the axial plug extends into and through the fluid passageway of the main body portion of the resilient applicator and into and through a dispensing orifice of the housing.

2. The oral care kit according to claim 1 wherein the polygonal perimeter edge comprises a plurality of rounded apex portions and a plurality of side portions, and wherein one of the plurality of side portions forms a distal most-portion of the resilient applicator and one of the plurality of apex portions forms a proximal-most portion of the working surface.

3. The oral care kit according to claim 2 wherein the plurality of side portions are substantially linear.

4. The oral care kit according to claim 2 wherein the plurality of side portions have a first radius of curvature, and the plurality of apex portions have a second radius curvature that is less than the first radius of curvature.

5. The oral care kit according to claim 1 wherein the removable cap comprises a tubular sidewall and a transverse end wall that collectively define an inner cavity, the axial plug extending axially from an inner surface of the transverse end wall and into the inner cavity.

6. The oral care kit of claim 5 wherein a gap exists between the working surface of the resilient applicator and the transverse end wall of the removable cap, a portion of the axial plug located within the gap.

7. The oral care kit according to claim 1 wherein the fluid passageway has a transverse cross-sectional area that tapers from the working surface to the bottom surface.

8. The oral care kit according to claim 1 wherein a portion of the axial plug protrudes from the working surface of the resilient applicator.

9. The oral care kit according to claim 1 wherein the resilient applicator is formed of a thermoplastic elastomer.

10. The oral care kit according to claim 1 wherein the resilient applicator comprises a plurality of nubs extending from the working surface.

11. The oral care kit according to claim 1 wherein the polygonal perimeter edge comprises a plurality of apex portions and a plurality of side portions, and wherein the resilient applicator comprises a plurality of elongated ridges extending from the working surface from one of the side portions to an opposite one of the side portions.

12. The oral care kit according to claim 11 wherein a plurality of channels are formed into the working surface between adjacent ones of the plurality of elongated ridges.

13. The oral care kit according to claim 1 wherein the fluid is a tooth whitening agent.

14. An oral care dispenser comprising:
a housing having an internal reservoir containing a fluid, the housing extending from a proximal end to a distal end along a longitudinal axis;
an applicator coupled to the distal end of the housing, the applicator comprising a dispensing orifice for dispensing the fluid from the reservoir;
wherein the applicator comprises a working surface that is oriented at an oblique angle to the longitudinal axis of the housing, the working surface defined by a polygonal perimeter edge, the polygonal perimeter edge comprising at least three apex portions and at least three side portions extending between each pair of adjacent apex portions, a first one of the side portions forming a distal most-portion of the applicator; and
a plurality of ridges extending from the working surface of the applicator from a second one of the side portions to a third one of the side portions.
