Abstract

An oral care implement having a multi-component handle is disclosed. In one aspect, the oral care implement comprises: a handle comprising a first component constructed of a first material and a second component constructed of a second material; the first component comprising: first, second and third depressions formed into an outer surface of the first component; and a first through-hole extending from a floor of the second depression to a floor of the third depression, the first through-hole extending through sidewalls of the first depression; and the second component comprising: a first portion disposed within the first depression, a second portion disposed within the second depression, and a third portion disposed within the first depression; and the first, second and third portions connected together to form an integral mass of the second material.

Claims

1. An oral care implement comprising:

a handle extending from a proximal end to a distal end along a longitudinal axis;

a head at the distal end of the handle;

the handle comprising a first component constructed of a first material and a second component constructed of a second material;

the first component comprising;

first, second and third longitudinally elongated depressions formed into an outer surface of the first component, the first, second and third longitudinally elongated depressions circumferentially spaced-apart from one another about the longitudinal axis; and

a first through-hole extending from the second longitudinally elongated depression to the third longitudinally elongated depression, the first through-hole extending through the first longitudinally elongated depression; and

the second component comprising;

a first lobe portion disposed within the first longitudinally elongated depression, a second lobe portion disposed within the second longitudinally elongated depression, and a third lobe portion disposed within the first third longitudinally elongated depression; and

the first, second and third lobe portions connected together to form an integral mass of the second material.

2. The oral care implement according to claim 1 wherein the first through-hole extends from a floor of the second longitudinally elongated depression to a floor of the third longitudinally elongated depression, the first through-hole extending through opposing sidewalls of the first longitudinally elongated depression.

3. The oral care implement according to claim 2 wherein the first through-hole extends transverse to the longitudinal axis.

4. The oral care implement according to claim 1 wherein the first material is an opaque material and the second material is a transparent material.

5. The oral care implement according to claim 1 wherein the first material is a first hard material and the second material is a first elastomeric material.

6. The oral care implement according to claim 1 wherein the first component comprises the head.

7. The oral care implement according to claim 1 wherein the first component further comprises:

a body portion;

a first longitudinal rib extending from the body portion toward the proximal end of the handle, the first longitudinal rib separating the first and second depressions;

a second longitudinal rib extending from the body portion toward the proximal end of the handle, the second longitudinal rib separating the second and third depressions; and

a third longitudinal rib extending from the body portion toward the proximal end of the handle, the third longitudinal rib separating the third and first depressions.

8. The oral care implement according to claim 1 wherein the handle further comprises a third component constructed of a third material, the third component disposed in a second through-hole extending through the body portion of the first component, and wherein the third component is a grip body, the third material being a second elastomeric material.

9. The oral care implement according to claim 1 wherein the first component further comprises a fourth longitudinally elongated depression formed into the outer surface of the first component, the first and fourth longitudinally elongated depressions located on opposite sides of the first component.

10. The oral care implement according to claim 9 wherein the first component comprises a third through-hole extending from a floor in the first longitudinally elongated depression to a floor of the fourth longitudinally elongate depression.

11. The oral care implement according to claim 9 wherein the second component comprises a fourth lobe portion disposed within the fourth longitudinally elongated depression, the first, second, third and fourth lobe portions connected together to form the integral mass of the second material.

12. The oral care implement according to claim 1 wherein each of the first, second and third lobe portions comprises an outer surface that remains exposed on the handle, and wherein the outer surfaces of the first, second and third lobe portions are isolated from one another by the outer surface of the first component.

13. An oral care implement comprising:

a handle extending from a proximal end to a distal end along a longitudinal axis;

a head at the distal end of the handle;

the handle comprising a first component constructed of a first material and a second component constructed of a second material;

the first component comprising;

a body portion; and

first, second and third longitudinal ribs extending from the body portion toward the proximal end of the handle; and

the second component comprising;

a first portion disposed between the first and third longitudinal ribs, a second portion disposed between first and second longitudinal ribs, and a third portion disposed between the second and third ribs.

14. The oral care implement according to claim 13 wherein the first longitudinal rib comprises a first bridge portion and the third longitudinal rib comprises a second bridge portion, and wherein a first gap exists beneath the first bridge portion and a second gap exists beneath the second bridge portion.

15. The oral care implement according to claim 13 wherein the second longitudinal rib branches into a first rib section and a second rib section, the first rib section converging with the first longitudinal rib and the second rib section converging with the second longitudinal rib, and wherein the second component comprises a fourth portion disposed between the first and second rib sections.

16. The oral care implement according to claim 13 wherein each of the first, second and third portions of the second component comprises an outer surface that remains exposed on the handle, and wherein the outer surfaces of the first, second and third portions are isolated from one another by an outer surface of the first component.

17. The oral care implement according to claim 13 wherein each of the first, second and third longitudinal ribs comprise a top surface that remains exposed on the handle.

18. The oral care implement according to claim 13 wherein the first component further comprises:

a first depression formed between the third and first longitudinal ribs;

a second depression formed between the first and second longitudinal ribs;

a third depression formed between the second and third longitudinal ribs;

a first through-hole extending from a floor of the second depression to a floor of the third depression, the first through-hole extending through opposing sidewalls of the first depression.

19. The oral care implement according to claim 13 wherein the handle further comprises a third component constructed of a third material, the third component disposed in a second through-hole extending through the body portion of the first component;
