A toothbrush including a head having an elastomeric support member is described herein. The elastomeric support member supports a plurality of upstanding projections. At least a portion of the upstanding projections include non-elastomeric projections and elastomeric projections.

A sustained-release matrix for dental application includes either an anti-microbial agent or a colorant that is released from the matrix when the matrix contacts water. The preferred matrices include a water-soluble polymer and a water-insoluble support resin.

Color changing matrix as wear indicator

A shaving unit that comprises at least one blade and a skin engaging member that has a surface for engaging the user's skin adjacent the blade edge is described herein. The shaving unit may be of a disposable cartridge type adapted for coupling to and uncoupling from a razor handle or may be integral with a handle so that the complete razor is discarded as a unit when the blade or blades become dulled. The blade edge (or edges) cooperate with skin engaging surfaces to define a shaving geometry. The skin engaging member is comprised of an elongated sheath (or skin engaging layer) made of a mixture of water insoluble matrix and an effective amount of shaving aid and a rigid core (or non-skin engaging layer) extending axially throughout said sheath. The axial position of the core need not be through the central axis.

Shaving system

A shaving unit that comprises at least one blade and a skin engaging member that has a surface for engaging the user's skin adjacent the blade edge. The shaving unit may be of a disposable cartridge type adapted for coupling to and uncoupling from a razor handle or may be integral with a handle so that the complete razor is discarded as a unit when the blade or blades become dulled. The blade edge (or edges) cooperate with skin engaging surfaces to define a shaving geometry. The skin engaging member is comprised on an elongated sheath (or skin engaging layer) made of a mixture of water insoluble matrix and an effective amount of shaving aid and a rigid core (or non-skin engaging layer) extending axially through out said sheath. The axial position of the core need not be through the central axis.

The invention is directed to a bristle ( ) suitable for use in a brush ( ) or the like, and in particular in a toothbrush. The bristle ( ) is made of a plastic material and includes preferably a circular area of cross-section. When viewed in cross-section, the bristle ( ) includes two sections ( ) with different properties. These sections ( ) are not in concentric relative arrangement. As a result, the bristle ( ) curves along its longitudinal axis. The curvature produces an improved cleaning action of the brush ( ).

This relates to an improved skin engaging member for use in razor blade; cartridge assemblies and shaving systems of the wet shave type. In an embodiment, there is provided a two-component, control-release shaving device consisting of(a) a sheath layer made from thermoplastic resins with openings therein and (b) a core region containing internal shaving aids. Potentially, the device can maintain surface appearance, control-release the shaving aids, minimize the degradation of the shaving aids, and prevent the shaving aids from being trapping in a strip. Furthermore, the addition of low-melt additives to the shaving aids becomes feasible and the compatibility between the shaving aids and the shaving aid carrier such as polystyrene in the lubricating strip composite becomes less critical.

Skin engaging member

Shaving aid strip for a razor cartridge

The present invention relates to a skin engaging member for use in a razor blade cartridge assembly or shaving systems of the wet shave type comprising an elongated flexible sheath region and at least one elongated, rigid core region. The core region is surrounded by the sheath such that the outer surface of the core does not intersect the outer surface of the sheath. Generally, the core or cores extend axially throughout the sheath and provide sufficient mechanical strength and rigidity to provide adequate mechanical strength and rigidity to provide adequate mechanical strength to the entire skin engaging member, as initially produced, during the shaving operation and after a significant amount of shaves.

Skin engaging member for razor blade assembly

An oral brush is provided that includes an elongated body, a head portion extending from the body, and a plurality of bristles, formed of particular thermoplastic elastomers, extending from the body. In various embodiments, the thermoplastic elastomer has a Shore A hardness of at least 30; the thermoplastic elastomer is selected from the group consisting of polyetheramides, polyesters, styrene-ethylene-butylene-styrene block copolymers, polyurethanes, polyolefin elastomers, and mixtures thereof; and the thermoplastic elastomer has a flexural modulus of at least 5 MPa.
