Abstract

An oral care implement having a base structure with a handle portion and a head portion. In one aspect, the handle portion comprises a core component and a shell component that surrounds the core component. The core component may include a body formed of a rigid material and decorative elements embedded within the body. The shell component may be formed of a substantially transparent material so that the decorative elements of the core are visible through the shell component.

First claim

What is claimed is:

1. An oral care implement comprising:
a base structure comprising a core component and a shell component surrounding the core component;
the shell component comprising a substantially translucent first rigid material, the shell component being monolithic; and
the core component comprising a solid, non-hollow, body formed of a second rigid material and a plurality of decorative elements, the plurality of decorative elements embedded within and dispersed throughout the second rigid material and visible through the shell component; wherein the plurality of decorative elements comprises at least one decorative element that is embedded within the second rigid material of the body and at least one decorative element that protrudes from an outer surface of the body;
wherein the plurality of decorative elements comprises discrete particles.

2. The oral care implement according to claim 1 wherein the base structure comprises a handle portion and a head portion, and further comprising tooth cleaning elements coupled to and extending from the head portion.

3. The oral care implement according to claim 2 wherein the shell component and the base component collectively form the handle portion of the base structure and wherein the shell component forms an entirety of the head portion of the base structure such that the core component does not extend to the head portion of the base structure.

4. The oral care implement according to claim 2 wherein the core component tapers towards the head portion of the base structure.

5. The oral care implement according to claim 1 wherein the shell component completely encapsulates the core component so that an entirety of an outer surface of the base structure is formed by the shell component and no portion of the core component is exposed on the outer surface of the base structure.

6. The oral care implement according to claim 1 further comprising a grip component formed of a thermoplastic elastomer covering at least a portion of the base structure.

7. The oral care implement according to claim 1 wherein the body is opaque.

8. The oral care implement according to claim 1 wherein the plurality of decorative elements comprises a plurality of particles embedded within the second rigid material of the body.

9. The oral care implement according to claim 8 wherein the body comprises a first color and at least one of the particles comprises a second color that is different than the first color.

10. The oral care implement according to claim 8 wherein the body is transparent or translucent and the plurality of particles are opaque.

11. The oral care implement according to claim 8 wherein the plurality of particles are selected from the group consisting of speckles, sparkles, flakes, glitter, microspheres, and pearlescent particles.

12. An oral care implement comprising:
a base structure comprising a handle portion and a head portion, tooth cleaning elements extending from the head portion;
the handle portion comprising a core component and a shell component, the shell component encapsulating the core component and forming an outer surface of the base structure;
the shell component formed of a substantially translucent first material; and
the core component comprising a body formed of a second rigid material and a plurality of decorative elements embedded within the second rigid material, at least one of the plurality of decorative elements forming a portion of an outer surface of the core component, the at least one of the plurality of decorative elements of the core component being visible through the substantially translucent first material of the shell component;
wherein the plurality of decorative elements comprises discrete particles.

13. The oral care implement according to claim 12 further comprising a grip component formed of a thermoplastic elastomer overmolded to the outer surface of the base structure.

14. The oral care implement according to claim 12 wherein the body is opaque.

15. The oral care implement according to claim 12 wherein the body is transparent or translucent.

16. The oral care implement according to claim 12 wherein the first material that forms the shell component is a rigid material.

17. The oral care implement according to claim 12 wherein the at least one of the plurality of decorative elements is located at an interface between the shell component and the core component.

18. The oral care implement according to claim 12 wherein the at least one of the plurality of decorative elements is exposed at the outer surface of the core component.

19. The oral care implement according to claim 12 wherein at least one of the plurality of decorative elements protrudes from an outer surface of the body of the core component.

20. An oral care implement comprising:
a base structure comprising a handle portion and a head portion, tooth cleaning elements extending from the head portion;
the handle portion comprising a core component and a shell component, the shell component encapsulating the core component and forming an outer surface of the base structure;
the shell component formed of a substantially translucent first material; and
the core component comprising a body formed of a second rigid material and a plurality of decorative elements embedded within the second rigid material, a first one of the plurality of decorative elements forming a portion of an outer surface of the core component, the plurality of decorative elements of the core component being visible through the substantially translucent first material of the shell component;
wherein the plurality of decorative elements comprises gas bubbles that form void spaces within the second rigid material of the body.
