Abstract

A toothbrush that enhances cleaning and user comfort while brushing. In one embodiment, the toothbrush comprises a cleaning element support member, or base member, that permits a head of the toothbrush to be comfortably received and manipulated within the user's mouth. In an embodiment, the support member comprises a head support having an overhanging portion and a portion free of an overhang.

First claim

What is claimed is:

1. A toothbrush comprising:
a head comprising a base,
a first flexible cleaning element support member extending from said base and comprising a first flexible stem and a first flexible support head having a portion overhanging a portion of said first flexible stem,
a second flexible cleaning element support member spaced from said first flexible cleaning element support member along said base and comprising a second flexible stem and a second flexible support head having an outer peripheral edge, and
a third flexible cleaning element support member positioned between said first and second flexible cleaning element support members;
wherein said third flexible cleaning element support member comprises a third flexible stem extending from said base; and
wherein a first portion of said outer peripheral edge of said second flexible support head overhangs a portion of said second flexible stem and a second portion of said outer peripheral surface of said second flexible support head is free of an overhang relative to said second flexible stem.

2. The toothbrush of claim 1 , wherein said first and second flexible support heads further comprise carriers from which at least one cleaning element extends.

3. The toothbrush of claim 1 , wherein each flexible cleaning element support member further comprises a flexion control member.

4. The toothbrush of claim 3 , wherein said flexible stems further comprise flexion control members.

5. The toothbrush of claim 3 , wherein said flexion control members are capable of flexing relative to said base, and wherein each flexible stem is formed of a resilient material.

6. The toothbrush of claim 1 , wherein each support head is spaced a distance from said base, said distance forming a gap between an undersurface of each support head and said base, and wherein each said support head is capable of deflecting into a respective one of the gaps in the direction of said base.

7. The toothbrush of claim 1 , wherein said second portion of said outer peripheral surface of said second support head and said second flexible stem form a continuous surface with an outer surface of said base.

8. The toothbrush of claim 1 , further comprising a neck and a handle, and wherein said base, said first flexible stem and a portion of said first flexible support head form a continuous surface along a portion of said toothbrush proximate said neck.

9. The toothbrush of claim 1 , wherein said flexible stems are formed of a resilient material.

10. The toothbrush of claim 1 , wherein said third flexible cleaning element support member comprises a third flexion control member positioned within said third flexible stem and a third flexible support head.

11. The toothbrush of claim 10 , wherein said third flexible cleaning element support member further comprises a portion overhanging a portion of said third flexible stem on opposite sides of said third flexible stem.

12. The toothbrush of claim 1 , wherein said third flexible cleaning element support member further comprises a carrier from which at least one cleaning element extends.

13. A toothbrush comprising:
a handle;
a head connected to said handle and extending along a longitudinal axis from a proximal end to a distal end, the head having:
a body portion;
a base member at a distal end of the head protruding outwardly from a front surface of the body portion, the base member being substantially non-movable relative to the body portion and comprising at least one outwardly extending tooth cleaning element;
a plurality of pods, each of the plurality of pods comprising at least one outwardly extending cleaning element, each of the plurality of pods movable relative to the body portion and resilient so that the at least one cleaning element of said plurality of pods is movable from an initial position and being returnable to said initial position;
a channel separating adjacent ones of the plurality of pods so that each of the plurality of pods can move independent of one another; and
a second base member protruding outwardly from the front surface of the body portion, the second base member being substantially non-movable relative to the body portion and comprising at least one outwardly extending tooth cleaning element, the second base member and the base member located on the longitudinal axis.

14. The toothbrush of claim 13 wherein a first portion of the base member forms a smooth continuous surface with a portion of a peripheral surface of the body portion at the distal end of the head.

15. The toothbrush of claim 14 wherein the base member comprises an overhanging portion opposite the first portion.

16. The toothbrush of claim 13 wherein the base member is located on the longitudinal axis.
