Portion for oral care implement

Oral care implement

An oral care implement having tooth cleaning elements and an elastomeric soft tissue cleanser. In one aspect, the oral care implement has a handle and a head coupled to the handle, an elastomeric soft tissue cleanser having a plurality of protuberances extending from a rear surface of the head, and a plurality of tooth cleaning elements extending from a front surface of the head. The protuberances of the elastomeric soft tissue cleanser collectively define a convex longitudinal side profile and comprise at least one convex transverse top profile. The plurality of tooth cleaning elements collectively define a concave longitudinal side profile and comprise at least one concave transverse top profile.

Toothbrush

An oral care implement that includes a handle and a head with a front surface. A plurality of tooth cleaning elements extend from the front surface. The plurality of tooth cleaning elements may include first and/or second sets of peripheral tooth cleaning elements located adjacent to opposing lateral edges of the head. The peripheral tooth cleaning elements may include elastomeric sleeve portions and bristle tuft portions. The elastomeric sleeve portions may be formed as a part of an integrally formed elastomeric component.

An oral care implement that includes a head having tooth cleaning elements including at least one conical tuft of bristles. The conical tuft of bristles defines a cavity that has a transverse cross-sectional area that increases with distance from the head. The tooth cleaning elements may also include one or more arcuate cleaning elements that at least partially surround the conical tuft. The tooth cleaning elements may also include multi-height bristle tufts along lateral sides of the head. Furthermore, the head may have two conical tufts such that one of the conical tufts is oriented at a smaller acute angle relative to the head than the other conical tuft and/or one of the conical tufts is taller than the other conical tuft.

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.

Oral care implement having multi-component handle

Oral care implement and portions thereof

An oral care implement including an elastomeric component that includes a bumper portion that forms a distal-most section of the peripheral surface and a wall portion located along a distal-most section of the perimeter edge and protruding above the front surface. The wall portion may include a first ramped portion, an apex portion, and a second ramped portion. The wall portion may include a plurality of spaced-apart ridges protruding from an outer surface of the bumper portion and an outer surface of the wall portion. An oral care implement is disclosed that includes a soft tissue cleanser having a plurality of protuberances of differing heights.

An oral care implement that includes a conical tuft of bristles. In one embodiment, the invention is an oral care implement that includes a handle and a head coupled to the handle, the head having a front surface. A plurality of tooth cleaning elements extend from the front surface of the head. The plurality of tooth cleaning elements include a conical tuft that has a bristle wall having an inner surface defining a cavity, the cavity having a transverse cross-sectional area that increases with distance from the front surface of the head. Furthermore, in some embodiments the bristle wall terminates in an annular top surface that is inclined relative to the front surface of the head. In some embodiments, the head includes more than one of the conical tufts, such as two of the conical tufts or four of the conical tufts.

An oral care implement having a tissue cleaning pad. In one aspect, the oral care implement includes a head having a front surface and an opposite rear surface. A plurality of tooth cleaning elements extend from the front surface of the head. A tissue cleaning pad is positioned on the rear surface of the head. The tissue cleaning pad has a planar top surface bounded by a perimetric edge and a plurality of protrusions extending from the planar top surface. The perimetric edge of the planar top surface of the tissue cleaning pad has a first portion that is flush with the rear surface of the head and a second portion that is raised relative to the rear surface of the head.

Tissue cleaner and oral care implement

An oral care implement having a head that achieves an enhanced cleaning action during brushing. In one embodiment, the invention can be an oral care implement having a handle extending from a proximal end to a distal end and a head having a front surface and an opposite rear surface. The head includes a cantilever extending from the distal end of the handle, a rigid plate that is spaced from the cantilever, and a resilient material that fills in the space between the cantilever and the rigid plate. The resilient material may be in direct contact with an entirety of a front surface of the cantilever and an entirety of a rear surface of the rigid plate. Furthermore, the cantilever, the rigid plate, and the resilient material may collectively form an exposed side surface of the head.

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.
