Abstract

An oral care implement having a multi-component handle is disclosed. In one aspect, the oral care implement comprises: a handle extending along a longitudinal axis; a head coupled to the handle; at least one tooth cleaning element extending from the head; the handle comprising: a first component constructed of a first material, the first component comprising a first component aperture; a second component constructed of a second material, the second component comprising the head and an anchor, the anchor located within the first component aperture and comprising a second component aperture; and a third component disposed within the second component aperture.

First claim

What is claimed is:

1. An oral care implement comprising:
a handle extending along a longitudinal axis;
a head at a distal end of the handle;
at least one tooth cleaning element extending from the head;
the handle comprising:
a first component constructed of a first hard plastic, the first component comprising a first component aperture;
a second component constructed of a second hard plastic, the second component comprising the head and an anchor, the anchor located within the first component aperture and comprising a second component aperture; and
a third component constructed of a first elastomeric material, the third component located within the second component aperture and in contact with both the first component and the second component within the second component aperture.

2. The oral care implement according to claim 1 wherein the first component aperture is a through-hole that extends between opposing outer surfaces of the first component.

3. The oral care implement according to claim 2 wherein the second component aperture is a through-hole that extends between opposing outer surfaces of the second component.

4. The oral care implement according to claim 3 wherein the second component aperture has a cross-sectional area that tapers with increasing depth from the opposing outer surfaces of the second component to form an apex edge.

5. The oral care implement according to claim 1 wherein the anchor comprises an annular structure that defines the second component aperture.

6. The oral care implement according to claim 5 wherein the annular structure comprises an upper surface that remains exposed.

7. The oral care implement according to claim 1 wherein the first component aperture extends along a first axis, the first axis being transverse to the longitudinal axis.

8. The oral care implement according to claim 1 wherein the second component aperture extends along a second axis, the second axis being transverse to the longitudinal axis.

9. The oral care implement according to claim 1 wherein the first component comprises a longitudinal protuberance extending from a distal end of the first component, the second component comprising a longitudinal recess in a transverse wall of the second component, and the longitudinal protuberance located within the longitudinal recess.

10. The oral care implement according to claim 1 wherein the third component has first and second opposing grip surfaces that remain exposed.

11. The oral care implement according to claim 1 wherein the first component comprises two transverse protuberances located on opposite sides of the second component aperture, the second component comprising first and second transverse openings, and the first and second transverse protuberances located within the first and second transverse openings.

12. The oral care implement according to claim 1 wherein the first hard plastic and the second hard plastic do not form a chemical bond with each other during an injection molding process.

13. The oral care implement according to claim 1 wherein the first elastomeric material and the second hard plastic form a chemical bond with each other during an injection molding process.

14. The oral care implement according to claim 1 wherein the second component further comprises a strap network wrapping around the first component.

15. The oral care implement according to claim 1 wherein one of the first or second hard plastics is substantially transparent and the other one of the first or second hard plastics is substantially opaque.

16. The oral care implement according to claim 1 wherein the first component comprises an annular structure that defines the first component aperture, and wherein the anchor comprises an annular structure having an outer surface having an annular groove, the annular structure of the first component nesting in the annular groove of the anchor.

17. An oral care implement comprising:
a handle extending along a longitudinal axis;
a head coupled to the handle;
at least one tooth cleaning element extending from the head;
the handle comprising:
a first component constructed of a first material, the first component comprising a first component aperture;
a second component constructed of a second material, the second component comprising the head and an anchor, the anchor located within the first component aperture and comprising a second component aperture; and
a third component disposed within the second component aperture and in contact with both the first component and the second component.

18. The oral care implement according to claim 17 wherein the first material is a first hard material and the second material is a second hard material, the first hard material being different than the second hard material.

19. The oral care implement according to claim 18 wherein the first hard material is a first hard plastic and the second hard material is a second hard plastic.
