Abstract

An oral care implement having a multi-component handle is disclosed. In one aspect, the oral care implement comprises: a handle; 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 hard material; and a second component constructed of a second hard material, the second component comprising a plurality of strips that collectively form a strap network that wraps around the first component.

First claim

What is claimed is:

1. An oral care implement comprising:
a handle extending along a longitudinal axis;
a head at the 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; and
a second component constructed of a second hard plastic, the second component comprising a body portion and a plurality of strips extending from the body portion and forming a strap network that wraps around the first component.

2. The oral care implement according to claim 1 wherein the second component comprises the head.

3. The oral care implement according to claim 1 wherein the plurality of straps extends longitudinally from the body portion toward the proximal end of the handle.

4. 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.

5. The oral care implement according to claim 1 wherein the plurality of strips comprises a first longitudinal strip, a second longitudinal strip and a third longitudinal strip.

6. The oral care implement according to claim 5 wherein the third strip branches into a first branch that converges with the first strip and a second branch that converges with the second strip.

7. The oral care implement according to claim 5 wherein the first and second strips collectively form a first strap that wraps around a proximal end of the first component.

8. The oral care implement according to claim 5 wherein the first and third strips collectively form a second strap that forms a loop on a first lateral surface of the handle.

9. The oral care implement according to claim 5 wherein the second and third strips collectively form a third strap that forms a loop on a second lateral surface of the handle.

10. The oral care implement according to claim 1 wherein the strap network comprises at least one strap that wraps around a proximal end of the first component.

11. The oral care implement according to claim 1 wherein the first component comprises a plurality of grooves formed into an outer surface of the first component, the plurality of strips located within the plurality of channels.

12. The oral care implement according to claim 1 wherein the first hard plastic is substantially transparent and the second hard plastic is substantially opaque.

13. The oral care implement according to claim 12 wherein the plurality of straps define a first window through the first component from first and second opposing outer surfaces of the handle; and wherein the plurality of straps define a second window through the third and fourth opposing outer surfaces of the handle.

14. The oral care implement according to claim 13 wherein the first outer surface of the handle is a first lateral surface of the handle, the second outer surface of the handle is a second lateral surface of the handle; the third outer surface of the handle is a front surface of the handle, and the fourth outer surface of the handle is a rear surface of the handle.

15. The oral care implement according to claim 1 wherein the first component comprises a first component aperture and the second component comprises an anchor that extends into the first component aperture, the anchor comprises a second component aperture, and wherein the handle further comprises a third component disposed within the second component aperture.

16. The oral care implement according to claim 1 wherein the first hard plastic and the second hard plastic are chemically incompatible with one another such that a chemical bond is not formed between the first and second plastics during an injection overmolding process.

17. An oral care implement comprising:
a handle;
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 hard material; and
a second component constructed of a second hard material, the second component comprising a plurality of strips that collectively form a strap network that wraps around the first component.
