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.

Gum-massaging oral brush

Dental flosses are provided that include a foam. Preferred flosses include a foam outer layer and a reinforcing core and may be formed as a multicomponent coextruded filament.

A shaving system that includes a housing, one or more blades mounted on the housing, a cap behind the blades on the housing, and a guard structure in front of the blades on the housing, the guard structure including flexible skin-engaging protrusions that engage a user's skin in front of the blades and a water leachable shaving aid composite positioned to deliver a shaving aid to the skin behind the flexible skin-engaging protrusions.

Shaving system with improved guard structure

The invention provides novel, improved wear indicating brush filaments and novel, improved coextrusion process for their manufacture. Essentially, the filaments of the present invention are coextruded filaments which include a longitudinal surface providing a boundary about the cross-sectional area of the filament and the longitudinal surface and/or the cross-sectional area presents a two colored region adapted to provide a visual signal indicative of wear in response to filament use. The filaments can be natural or synthetic materials. In filaments of the present invention, the colored region provides an initial color or color intensity viewable to the user. As wear is produced by continuing use of the filaments, the intensity of the colored region changes to a point which signals the user that the filament no longer provides the requisite performance characteristics for effectively performing its assigned function.
