Oral care implement
An oral care implement with a soft tissue cleanser is provided to effectively cleanse the soft tissue of the mouth with comfort and a reduced risk of injury to the user. In one construction, a projection is formed of a combination of a hard material and a soft material. The hard material provides good stability for cleaning debris from the tongue or other tissue while the soft material provides comfort and a reduced risk of injury.
1. An oral care implement comprising an elongated handle, a head connected to the elongated handle, at least one projection protruding from the head to cleanse soft tissue within a user's mouth, the projection being formed of two components including a first component composed of a first material and a second component composed of a second material, wherein the first and second materials are different and the second component is composed of a thermoplastic elastomer and wherein the at least one projection extends laterally across substantially the entire surface of the head in a non-linear configuration, wherein the first component is formed as a unitary portion of the head and wherein the second component is molded over and integral with the first component.
2. An oral care implement in accordance with claim 1 wherein the first material is a relatively hard material and the second material is a relatively soft material.
3. An oral care implement in accordance with claim 2 wherein the first component defines a base protruding from the head and the second component at least partially overlies the base.
4. An oral care implement in accordance with claim 3 wherein the base includes a tip remote from the head to engage and clean the soft tissue, and the second component overlies at least the tip of the base.
5. An oral care implement in accordance with claim 4 wherein the tip has a narrow remote end to clean the soft tissue.
6. An oral care implement in accordance with claim 4 wherein the second component covers only the tip.
7. An oral care implement in accordance with claim 3 wherein the base protrudes from a first side of the head, and the second component overlies substantially the entire first side of the head.
8. An oral care implement in accordance with claim 7 wherein teeth cleaning elements extend from a second side of the head, which is opposite the first side.
9. An oral care implement in accordance with claim 3 wherein the base includes a tip remote from the head to engage and clean the soft tissue, and the second component overlies substantially the entire base except for the tip.
10. An oral care implement in accordance with claim 9 wherein the head includes a recess into which a portion of the second component is secured.
11. An oral care implement in accordance with claim 1 wherein the first component defines an outwardly directed tip to contact the soft tissue, and the second component extends from the head to the tip to define an outer surface against which the soft tissue moves to the tip.
12. An oral care implement in accordance with claim 1 wherein the projection has a generally constant cross-section.
13. An oral care implement in accordance with claim 1 wherein the head is sized for insertion into a mouth of a user.
14. An oral care implement in accordance with claim 1 wherein the first material is polypropylene and the second material is a thermoplastic elastomer.
15. An oral care implement in accordance with claim 1 wherein the at least one projection protrudes from the head for a height between 0.5 to 1.0 millimeters.
16. An oral care implement in accordance with claim 1 comprising a plurality of the projections extending laterally across substantially the entire surface of the head in a laterally curved configuration, the projections having at least two different lateral radii of curvature.
17. A toothbrush comprising:
an elongated handle;
a head connected to the handle, the head having a first side and an opposite second side;
at least one cleaning element extending from the first side;
at least one projection protruding from the second side of the head to cleanse soft tissue within a user's mouth, the at least one projection extending laterally across substantially the entire surface of the head as a curved ridge; and
the projection being formed of two components including a first component constructed of a relatively hard material and a second component constructed a relatively soft material, wherein the first component is formed as a unitary portion of the head, and wherein the second component is molded over and integral with the first component.
