An oral hygiene implement includes a cleaning element carrier and a body. The body has a proximal end and a distal end. The cleaning element carrier has a first area and a second area wherein the second area is disposed inboard of the first area. The first area is attached to the body while the second area is unattached to the body. A bending element is disposed between the first area and the second area, thereby allowing the second area to bend/flex while the first area stays fixed to the body.

Oral hygiene implements having flexible elements, and methods of making the same

A toothbrush head having a top surface and a bottom surface opposite the top surface is described herein. The head has a first portion, a second portion, and an opening between the first portion and the second portion. The opening extends from the top surface to the bottom surface. A first plurality of contact elements are positioned on the first portion and the second portion. A second plurality of contact elements are positioned on the first portion and the second portion. Each of the second plurality of contact elements has an elastomer.

Toothbrush head

Tooth cleaning devices. An embodiment of a tooth cleaning device includes: an elongated head sized to fit in an oral cavity. The elongated head having a first surface and a neck extending from the head. A first tooth cleaning element having a plurality of upstanding wiping members extends upward from below the first surface and extends radially outward from a center of the first tooth cleaning element. Each upstanding wiping member has a free outermost edge that extends upwards substantially from the first surface to the top of the wiping member. A plurality of upstanding arcuate shaped second tooth cleaning elements secured to the head and located outboard of the first tooth cleaning element are also provided. In addition, a plurality of upstanding third tooth cleaning elements are secured to the head and border an edge of the first surface. The third tooth cleaning elements have a circular cross-sectional area.

Toothbrushes

An oral care implement may include a base portion sized for insertion into an oral cavity and a plurality of flexible, elastomeric elements extending from the base portion, wherein each of the plurality of flexible, elastomeric elements comprises an edge, wherein at least one of the edges comprises a micro edge, and wherein the plurality of flexible, elastomeric elements comprises an element density of less than about 5 mm.

Oral care products and methods of using and marking the same

Toothbrushes are provided which have various features that may include one or more tooth cleaning elements having a variety of shapes and sizes, one or more gum treating elements having a variety of shapes and sizes, and/or one or more soft tissue/tongue treating elements having a variety of shapes and sizes.

A head for an electric toothbrush includes a support member having a plurality of holes extending completely therethrough. A plurality of tufts of bristles each extends through one of the holes. A first brushing end of each tuft projects from a first side of the support member. Each tuft is prevented from being withdrawn from its hole when a tensile force is applied to the first end of each tuft along a long axis of the tuft. A resilient cushion is positioned adjacent a second side of the support member such that a second end of each tuft can contact the cushion. When a compressive force is applied to the first end of each tuft along the long axis of each tuft, each tuft can move in its hole in a first direction into the cushion. When the compressive force is removed the cushion causes each tuft to move in its hole in a second direction substantially opposite the first direction.

Electric toothbrush head

Toothbrush heads, e.g., for power toothbrushes, are provided. An embodiment of the toothbrush heads include a support structure, a plurality of upstanding accurate members extending upward from a surface of the support structure forming an open center area, a second cleaning element disposed within the open center area and plurality of bristle tufts extending from the support structure and at least partially surrounding at least one of the plurality of arcuate segments

Toothbrush heads, e.g., for power toothbrushes, are provided. The toothbrush heads include a support member, a resilient member extending from the support member, and a plurality of tufts of bristles extending from the support member and at least partially surrounding the member. The resilient member may be cup-shaped, fan-shaped, or textured.

Methods and devices are provided for forming filament bundles of long, continuous strands of filaments. The methods include bonding the long, continuous stands of filaments together so that they cannot move axially with respect to any other filament in the bundle. Methods of bonding include ultrasonic welding, freezing or applying adhesive.

Brush filament bundles and preparation thereof

Methods of manufacturing razor cartridges are provided. One method includes loading a support portion of a supported blade into an elongated blade slot defined by a core member, the core member being configured to define a portion of a molding cavity defining the shape of the cartridge housing; and delivering a resin to the molding cavity to form the housing and capture a portion of the blade in the resin. In another method, a plurality of razor cartridges are manufactured substantially simultaneously by (a) removably mounting each blade on a core member; (b) placing each core member in a molding cavity; and (c) delivering a resin to the molding cavities to form at least a portion of the cartridge housing and capture a portion of the blade in the resin. In other methods a flexible region is provided adjacent the blade ends by: (a) delivering a compliant material to the molding cavity to capture at least the ends of the blade; (b) placing the blade and molded compliant material in a second molding cavity defining the shape of the molded housing; and (c) delivering a resin to the second molding cavity to form the molded housing, or by (a) providing coring areas in the molding cavity beyond each of the blade ends, configured to provide a flexible region of plastic adjacent each blade end in the finished product; and (b) delivering a resin to the molding cavity. In some methods, the resin is delivered through a gate that is positioned so that a substantial portion of the resin flow goes by the blade ends before the molding cavity is filled.
