Abstract

An oral care implement including an elongated body having a head portion supporting plurality of tooth cleaning elements and a handle portion defining an outer surface. A grip control component is disposed on the handle portion and includes a pair of transversely spaced apart control surfaces separated by a longitudinally extending channel. The control surfaces are elevated above the outer surface of the handle portion and positioned to engage a user's thumb. The control component is operable to tilt the head portion at an upward or downward angle relative to a vertical plane of a user's teeth when the control component is grasped between the user's thumb and forefinger for producing a proper brushing angle at the gum line.

First claim

What is claimed is:

1. An oral care implement comprising:
an elongated body extending along a longitudinal axis and comprising a head portion and a handle portion having an outer surface;
a plurality of tooth cleaning elements extending from a front surface of the head portion of the elongated body; and
a grip-enhancement member comprising a grip control component disposed on the handle portion of the elongated body to form a control section of the handle of the oral care implement, the grip control component comprising:
a first grip element comprising a first upstanding wall and a first control surface extending from the first upstanding wall;
a second grip element comprising a second upstanding wall and a second control surface extending from the second upstanding wall; and
the first and second grip elements transversely spaced apart from one another and separated by a longitudinally extending channel, the longitudinally extending channel defined by a floor and the first and second upstanding walls, the floor being formed by an exposed portion of the handle portion of the elongated body that is located between the first and second upstanding walls;

wherein the control section is located adjacent a neck of the oral care implement and is diametrically enlarged relative to a finger gripping section of the handle, the finger gripping section extending from a proximal end of the oral care implement to the control section; and
wherein the grip-enhancement member comprises a finger grip control portion along the finger gripping section of the handle, the finger grip control portion comprising a base portion extending along a rear surface of the elongated body, a first set of protuberances protruding from the base portion on a first side of the longitudinal axis of the elongated body and configured for engagement with a finger of a user's right hand when the oral care implement is gripped by the user's right hand, and a second set of protuberances protruding from the base component on a second side of the longitudinal axis of the elongated body and configured for engagement with a finger of a user's left hand when the oral care implement is gripped by the user's left hand.

2. The oral care implement according to claim 1 wherein the first and second sets of protuberances are arranged in a V-shape such that the protuberances of the first and second sets of protuberances are located a greater distance from the longitudinal axis with increasing distance from the proximal end of the oral care implement.

3. The oral care implement according to claim 1 , wherein the elongated body is formed of a hard plastic and the grip-enhancement member is formed of a resilient material that overlies the elongated body.

4. The oral care implement according to claim 1 , wherein the first and second control surfaces are located on opposite sides of a first reference plane that includes the longitudinal axis and is orthogonal to the front surface of the head portion, wherein the first reference plane intersects the longitudinally extending channel, and wherein the longitudinally extending channel is aligned with and extends along the first reference plane.

5. The oral care implement according to claim 1 wherein the first and second grip elements have concave upper edges facing a distal end of the handle and concave lower edges facing a proximal end of the handle.

6. The oral care implement according to claim 5 , wherein the longitudinally extending channel has a first channel section, a second channel section, and a narrowed waist section, the first channel section being located between the concave upper edges of the first and second grip elements, the second channel section being located between the concave lower edges of the first and second grip elements, and the narrowed waist section being located between the first and second channel sections and between the first and second upstanding walls.

7. The oral care implement according to claim 6 , wherein each of the first and second channel sections has a width that increases with increasing distance from the narrowed waist section.

8. The oral care implement according to claim 1 , wherein each of the first and second control surfaces includes a plurality of protuberances extending therefrom.

9. The oral care implement according to claim 8 , wherein the plurality of protuberances are nubs having a maximum diameter, wherein the longitudinally extending channel has a minimum width measured between the first and second upstanding walls, the minimum width of the longitudinally extending channel being greater than the maximum diameter of the nubs.

10. The oral care implement according to claim 1 , wherein the control section of the handle comprises a transverse cross-sectional profile comprising a first quadrant, a second quadrant adjacent the first quadrant, a third quadrant adjacent the second quadrant, and a fourth quadrant adjacent the third and first quadrants; wherein the first control surface is confined to the first quadrant and the second control surface is confined to the second quadrant; wherein the transverse cross-sectional profile comprises an apex at the intersection of the fourth and third quadrants; and wherein the longitudinally extending channel is located in both of the first and second quadrants.

11. An oral care implement comprising:
a body portion formed of a rigid material that extends along a longitudinal axis, the body portion comprising a thumb grip section and a finger grip section;
a monolithic mass of resilient material coupled to the body portion, the monolithic mass of resilient material comprising:
a thumb grip control portion located along the thumb grip section of the body portion, the thumb control portion comprising:
a first grip element comprising a first upstanding wall that protrudes from the body portion, the first upstanding wall facing the longitudinal axis of the body portion and located on a first side of the longitudinal axis of the body portion;
a second grip element comprising a second upstanding wall that protrudes from the body portion, the second upstanding wall facing the longitudinal axis of the body portion and located on a second side of the longitudinal axis of the body portion so that an exposed portion of the body portion extends between the first and second upstanding walls; and
a longitudinally extending channel defined by the exposed portion of the body portion and the first and second upstanding walls.

12. The oral care implement according to claim 11 wherein the first grip element comprises a first control surface and the second grip element comprises a second control surface, the first control surface intersecting the first upstanding wall at a first control edge that is elevated relative to the exposed portion of the body portion, and the second control surface intersecting the second upstanding wall at a second control edge that is elevated relative to the exposed portion of the body portion.

13. The oral care implement according to claim 12 further comprising a plurality of protuberances extending from the first and second control surfaces of the first and second grip elements.

14. The oral care implement according to claim 13 wherein the plurality of protuberances are nubs having a maximum diameter and wherein the longitudinally extending channel has a minimum width measured between the first and second upstanding walls, the minimum width of the longitudinally extending channel being greater than the maximum diameter of the nubs.

15. The oral care implement according to claim 11 wherein the body portion comprises a handle port
