Abstract

An oral care implement is provided having a handle and a head with a soft tissue cleanser and/or tooth cleaning elements. The tissue cleanser may include a plurality of projections for cleaning the soft tissue, which may include cleaning between the papillae of a user's tongue. The soft tissue cleanser may have an elongate ridge projecting from the head in generally the same direction as the projections. The handle may include a base with a gripping region and a projection protruding from the base in the gripping region. The handle may also have a grip surface with a plurality of spaced slot openings exposing portions of the base. The grip body may form opposite finger grips on the handle.

Claims (38)

1. An oral care implement comprising:

a handle;

a head formed of a rigid material and having a first face, the head having a proximal end connected to the handle, a distal end, lateral sides and a longitudinal axis;

a soft tissue cleanser in the form of a ring of elastomeric material defining a central opening, the soft tissue cleanser disposed on the first face of the head so that a central portion of the head is exposed via the central opening;

the soft tissue cleanser comprising a plurality of projections protruding outwardly from the ring of elastomeric material;

wherein the projections of the soft tissue cleanser adjacent the sides of the head comprise first ridges oriented to generally radiate from the central opening: and

wherein the projections of the soft tissue cleanser adjacent the proximal end of the head are nubs.

2. The oral care implement of claim 1 , wherein the central portion is a depression formed into the first surface of the head having, a bottom surface and a side wall formed from the rigid material.

3. The oral care implement of claim 2 , wherein at least a portion of the side wall of the depression extends above the first face of the head so as to form an elongated scraper.

4. The oral care implement of claim 3 , wherein the elongated scraper is a curved ridge located adjacent the distal end of the head.

5. The oral care implement of claim 3 , wherein the elongated scraper is a substantially continuous boundary around the central portion.

6. The oral care implement of claim 1 , wherein the projections of the soft tissue cleanser along the sides of the head further comprise second ridges oriented to be generally transverse to the first ridges.

7. The oral care implement of claim 1 , wherein the ridges each include a top edge angled away from the first face to provide increasing engagement with the soft tissues as the first face is pressed into the soft tissues.

8. The oral care implement of claim 1 , wherein the ring of elastomeric material is substantially elliptically shaped.

9. The oral care implement of claim 1 , further comprising tooth cleansing elements extending from a second face of the head for cleaning a user's teeth.

10. The oral care implement of claim 9 , wherein the tooth cleansing elements extend in a direction substantially opposite the direction in which the projections protrude to permit simultaneous engagement of a user's teeth via the tooth cleansing elements along with engagement of soft tissues opposed to the teeth via the soft tissue cleanser.

11. The oral care implement of claim 9 , further comprising a drive mechanism for moving at least one of the tooth cleansing elements and projections.

12. The oral care implement of claim 11 , wherein the drive mechanism includes a mechanical vibratory device.

13. The oral care implement of claim 11 , wherein the drive mechanism simultaneously moves both the tooth cleansing elements and projections.

14. An oral care implement comprising:

a handle;

a head having a first face and an opposite second face;

a soft tissue cleanser for cleansing soft tissue in a user's mouth disposed on the first face of the head, the soft tissue cleanser comprising:

a ring of projections protruding outward from the first face for dislodging microbial and other debris from the soft tissue, the ring of projections comprising nubs and ridges;

an elongate ridge projecting outward from the first face for dislodging microbial and other debris from the soft tissue, the elongate ridge disposed within the ring of projections; and

a central portion on the first face substantially bordered by the elongate ridge and by a surface of the first face, the central portion having a depression having a bottom surface located at a depth below the first face; and

tooth cleansing elements extending from the second face in a direction substantially opposite the elongate ridge and the ring of projections.

15. An oral care implement comprising:

a handle;

a head formed of a rigid material and having a first face and a central axis generally aligned with the handle and traversing a central portion of the first face:

an oval depression formed into the first face of the head, the depression having a bottom surface and a continuous upstanding side wall that encloses the depression;

a soft tissue cleanser disposed on the first face of the head for cleansing soft tissue in a user's mouth, the soft tissue cleanser comprising soft tissue cleanser elements disposed generally symmetrically about the central axis: and

wherein the at least a portion of the side wall of the depression extends above the first face so as to form an elongated ridge; and

wherein the soft tissue cleanser elements include nubs and ridges projecting from the first face.

16. The oral care implement of claim 15 , wherein the soft tissue cleanser elements include a ring of projections protruding outwardly from the first face.

17. The oral care implement of claim 16 , wherein the ring generally forms an ellipse.

18. The oral care implement of claim 15 , further comprising tooth cleansing elements extending from a second face of the head for cleaning a user's teeth.

19. The oral care implement of claim 18 , wherein the tooth cleansing elements extend in a direction substantially opposite the direction in which the soft tissue cleanser elements are oriented outwardly from the first face to permit simultaneous engagement of a user's teeth via the tooth cleansing elements along with engagement of soft tissues opposed to the teeth via the soft tissue cleanser.
