Abstract

In some embodiments an oral care implement herein may be embodied as a toothbrush having a head disposed at a distal end of a handle. The head may include a fixed bristle support and at least two movable bristle supports, movable relative to the fixed bristle support and relative to each other. An actuator is disposed to actuate the movable bristle supports between a brushing position in which bristles on the fixed bristle support and the movable bristle supports are substantially parallel and an interdental cleaning position in which the movable bristle supports are moved relative to each other such that the bristles on the movable bristle supports are angled toward each other. In the interdental cleaning position, the bristles may form a point or similar bristle tip, which may be useful for interdental cleaning.

First claim

What is claimed is:

1. An oral care implement comprising:
a handle extending from a proximal end to a distal end;
a head disposed at the distal end of the handle, the head comprising:
a fixed bristle member comprising a first plurality of bristles on a fixed bristle support,
a first movable bristle member comprising a second plurality of bristles on a first movable bristle support, and
a second movable bristle member comprising a third plurality of bristles on a second movable bristle support; and

an actuator configured to move the first movable bristle member and the second movable bristle member to selectively place the head in a brushing position in which the second plurality of bristles and the third plurality of bristles are disposed in a first orientation relative to the first plurality of bristles or in an interdental cleaning position in which the second plurality of bristles and the third plurality of bristles are angled relatively toward each other to form a bristle tip and the bristle tip is angled relative to the first plurality of bristles;
wherein the first movable bristle member rotates about a first axis of rotation and the second movable bristle member rotates about a second axis of rotation, the first and second axes of rotation being non-parallel.

2. The oral care implement of claim 1 , wherein the actuator comprises an elongate member contacting the first movable bristle member and the second movable bristle member and movable relative to the fixed bristle member.

3. The oral care implement of claim 2 , wherein the elongate member contacts the first movable bristle member and the second movable bristle member proximate a first end and is fixed at an opposite, second end, to an actuatable member.

4. The oral care implement of claim 3 , wherein the actuatable member is configured for actuation by a user to move the actuator between the brushing position and the interdental cleaning position.

5. The oral care implement of claim 2 , wherein the elongate member is fixed to at least one of the first movable bristle member or the second movable bristle member.

6. The oral care implement of claim 1 , further comprising a first hinge connecting the first movable bristle member to the fixed bristle member and a second hinge connecting the second movable bristle member to the fixed bristle member.

7. The oral care implement of claim 6 , wherein the first hinge and the second hinge are living hinges.

8. The oral care implement of claim 6 , wherein the first hinge is configured to allow rotation of the first movable bristle member about the first axis of rotation, the second hinge is configured to allow rotation of the second movable bristle member about the second axis of rotation, and the first axis and the second axis are angled relative to each other and a longitudinal axis of the head.

9. The oral care implement of claim 1 , wherein, in the interdental cleaning configuration, the bristle tip is angled relatively toward the first plurality of bristles.

10. The oral care implement of claim 1 , wherein, in the interdental cleaning configuration, the bristle tip is angled relatively away from the first plurality of bristles.

11. An oral care implement comprising:
a handle;
a head disposed at a distal end of the handle, the head comprising:
a fixed cleaning member support,
a first cleaning member disposed on the fixed cleaning member support,
a first movable cleaning member support movable relative to the fixed cleaning member support,
a second cleaning member disposed on the first moveable cleaning member support,
a second movable cleaning member support moveable relative to the cleaning member support and the first movable cleaning member support, and
a third cleaning member disposed on the second moveable cleaning member support; and

an actuator disposed to pivot the first movable cleaning member support relative to the fixed cleaning member support about a first axis, to pivot the second movable cleaning member support relative to the fixed cleaning member support about a second axis, and the second movable cleaning member support relative to the fixed cleaning member support, and to actuate at least one of the first movable cleaning member and the second movable cleaning member support relative to each other;
a first hinge connecting the first movable cleaning element support to the fixed cleaning element support and a second hinge connecting the second movable cleaning element support to the fixed bristle support.

12. The oral care implement of claim 11 , wherein the actuator comprises an elongate member disposed in the oral care implement.

13. The oral care implement of claim 12 , wherein the elongate member extends from a proximal end disposed in the handle to a distal end contacting at least one of the first movable cleaning member support or the second movable cleaning member support.

14. The oral care implement of claim 11 , wherein the first cleaning element comprises a first plurality of bristles, the second cleaning element comprises a second plurality of bristles, and the third cleaning element comprises a third plurality of bristles.

15. The oral care implement of claim 14 , wherein the actuator is adjustable between a first position that configures the head in a first configuration and a second position that configures the head in a second configuration, wherein in the first configuration the second plurality of bristles and the third plurality of bristles are arranged in a first orientation and wherein in the second configuration the second plurality of bristles and the third plurality of bristles are angled relatively toward each other.

16. The oral care implement of claim 15 , wherein in the second configuration distal ends of the bristles comprising the second plurality of bristles are angled toward distal ends of the bristles comprising the third plurality of bristles to form a bristle tip.

17. An oral care implement comprising:
a handle;
a head disposed at a distal end of the handle, the head comprising:
a fixed cleaning member support,
a first cleaning member disposed on the fixed cleaning member support,
a first movable cleaning member support movable relative to the fixed cleaning member support,
a second cleaning member disposed on the first moveable cleaning member support,
a second movable cleaning member support moveable relative to the cleaning member support and the first movable cleaning member support, and
a third cleaning member disposed on the second moveable cleaning member support; and

an actuator disposed to pivot the first movable cleaning member support relative to the fixed cleaning member support about a first axis, to pivot the second movable cleaning member support relative to the fixed cleaning member support about a second axis, and the second movable cleaning member support relative to the fixed cleaning member support, and to actuate at least one of the first movable cleaning member and the second movable cleaning member support relative to each other;
wherein the actuator comprises an elongate member disposed in the oral care implement;
wherein the elongate member includes at the distal end a first member contacting the first movable cleaning member support and a second member contacting the second movable cleaning member support.

18. The oral care implement of claim 17 , wherein the first member is fixed relative to the second member.

19. A toothbrush comprising:
a handle extending from a proximal end to a distal end; and
a head disposed at the d
