Abstract

An oral care implement ( 100 ) in one embodiment includes an elongated body ( 101 ) comprising a head portion ( 110 ) supporting plurality of tooth cleaning elements ( 111 ) and a handle portion ( 120 ) defining an outer surface ( 127 ). A grip control component ( 130 ) is disposed on the handle portion ( 120 ) and includes a pair of transversely spaced apart control surfaces ( 132 ) separated by a longitudinally extending channel ( 133 ). The control surfaces ( 132 ) are elevated above the outer surface ( 127 ) of the handle portion ( 120 ) and positioned to engage a user's thumb. The control component ( 130 ) is operable to tilt the head portion ( 110 ) at an upward or downward angle relative to a vertical plane of a user's teeth when the control component ( 130 ) is grasped between the user's thumb and forefinger for producing a proper brushing angle at the gum line.

Claims (27)

1. An oral care implement comprising:

an elongated body extending along a longitudinal axis, the elongated body including a head portion and a handle portion comprising an outer surface, the elongated body formed of a rigid material;

a plurality of tooth cleaning elements extending from a front surface of the head portion;

first and second grip elements on the handle portion of the elongated body to form a control section of a handle of the oral care implement, the first and second grip elements transversely spaced apart from one another; and

a grip-enhancement member overlying a rear portion of the outer surface of the handle portion, the first and second grip elements being integrally formed with the grip-enhancement member;

each of the first and second grip elements formed of a resilient material and protruding from the outer surface of the handle portion of the elongated body to form a longitudinally extending channel therebetween, the channel defined by a floor formed by a front surface of the handle portion of the elongate body, a first upstanding wall of the first grip element, and a second upstanding wall of the second grip element;

wherein the grip-enhancement member and the first grip element collectively form a first closed loop on a first lateral side surface of the handle portion, the outer surface of the handle portion exposed through the first closed loop; and

wherein the grip-enhancement member and the second grip element collectively form a second closed loop on a second lateral side surface of the handle portion opposite the first lateral side surface of the handle portion, the outer surface of the handle portion exposed through the second closed loop.

2. The oral care implement according to claim 1 , wherein the control section of the handle 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.

3. The oral care implement according to claim 1 , wherein each of the first and second grip elements includes a plurality of protuberances extending outwardly therefrom.

4. The oral care implement according to claim 1 , further comprising:

the first and second grip elements 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;

the longitudinally extending channel aligned with and extending along the first reference plane;

the longitudinally extending channel defined by:

a floor formed by a portion of the outer surface of the handle portion;

a first upstanding wall formed by a side surface of the first grip element; and

a second upstanding wall formed by a side surface of the second grip element.

5. The oral care implement according to claim 1 , wherein each of the first and second grip elements comprises an arcuate control surface.

6. The oral care implement according to claim 1 wherein the longitudinally extending channel has a floor formed of the rigid material.

7. An oral care implement comprising:

an elongated body extending along a longitudinal axis, the elongated body including a head portion and a handle portion comprising an outer surface, the elongated body formed of a rigid material;

a plurality of tooth cleaning elements extending from a front surface of the head portion;

first and second grip elements on the handle portion of the elongated body to form a control section of a handle of the oral care implement, the first and second grip elements transversely spaced apart from one another; and

a grip-enhancement member overlying a rear portion of the outer surface of the handle portion, the first and second grip elements being integrally formed with the grip-enhancement member;

each of the first and second grip elements formed of a resilient material;

wherein the grip-enhancement member and the first grip element collectively form a first closed loop on a first lateral side surface of the handle portion, the outer surface of the handle portion exposed through the first closed loop; and

wherein the grip-enhancement member and the second grip element collectively form a second closed loop on a second lateral side surface of the handle portion opposite the first lateral side surface of the handle portion, the outer surface of the handle portion exposed through the second closed loop.
