The invention relates to an oral care instrument, in particular a toothbrush or a tongue cleaner, including at least one cleaning element made from a first plastic component, wherein the first plastic component contains a thermoplastic elastomer and activated carbon. The invention also relates to a method for producing an oral care instrument, in particular a toothbrush or a tongue cleaner, including the following steps: a) providing a first plastic component by adding activated carbon to a thermoplastic elastomer, and b) producing a cleaning element from the first plastic component using an injection molding method.

A wheel and lug nut cleaning device providing a single tool for cleaning behind and between spokes of a wheel rim, the lug nuts, and rim cavities around the lug nuts by including a static spine having an exterior end, an angled front portion proximal thereto, an interior end, and a rear portion. A shape-retaining non-abrasive core encircles most of the spine. A sheath, removably encompassing and conforming to the core, has a tapered forward end, a rearward end, a central opening in the rearward end, and semi-obround microfiber flanges extended from the core. A lug nut and rim cavity-cleaning body, removably disposed on the interior end, has a substantially disc-shaped central base with an attachment end engageable to the central opening and flexible cleaning flanges radially disposed thereon and a cover removably disposed thereon, including a central ring and extensions radially disposed therefrom to cover the cleaning flanges.

Methods of providing sustained sterilization of thermoplastics; providing thermoplastics that have the capacity to dispense sodium fluoride, and, a method of providing sustained sterilization of thermoplastics and providing thermoplastics that have the capacity to dispense sodium fluoride, both from the same thermoplastic article.

Disclosed is a moving handrail sterilizing apparatus. The moving handrail sterilizing apparatus includes: a moving handrail; a first sterilizing unit which is disposed so as to be in contact with one side of the moving handrail and wipes away foreign substances on a surface of the handrail; a sterilizing panel which is disposed on one side of the first sterilizing unit and irradiates the first sterilizing unit with ultraviolet rays and plasma; a second sterilizing unit, which is spaced a certain distance from the first sterilizing unit along the direction in which the moving handrail moves, is provided below the moving handrail and provides a sterilizing agent to the moving handrail; and an air blower fan which is disposed between the second sterilizing unit and the moving handrail and blows air so that the sterilizing agent is uniformly supplied to the moving handrail.

An oral care implement including at least one spiral bristle. In one aspect, the invention can be an oral care implement having a handle; a head coupled to the handle; at least one bristle tuft extending from the head, the at least one bristle tuft comprising at least one spiral bristle comprising coextruded first and second strand components that are intertwined together to form the at least one spiral bristle; the first strand component comprising a first plastic and a first oral care additive; and the second strand component comprising a second plastic and a second oral care additive, Tine rein the first oral care additive is different than the second oral care additive.

Disclosed are an antimicrobial nylon composite material, a preparation method thereof and an application in brushes. The antimicrobial nylon composite material includes a nylon matrix material, an antimicrobial agent, a reinforcing agent, and a plant material. The plant material includes tea tree essential oil, clove oil and eucalyptus essential oil. In the present disclosure, the growth and reproduction of bacteria can be effectively inhibited by using a silver ion antimicrobial agent and the plant material, thereby providing a stronger antimicrobial property. Meanwhile, the mechanical strength and wear resistance of the material can be significantly improved by introducing the reinforcing agent, a fiber reinforcing agent and a particle reinforcing agent into a nylon matrix to make the manufactured brush have a longer service life and better performance.

A toilet brush that is self-cleaning and retractable for hygienic storage. The toilet brush includes a handle, a connecting shaft, a tubular enclosure, a removable brush, a plurality of ultraviolet (UV) light sources, and a battery. The handle is terminally connected to the connecting shaft to provide a user with a grasping element. The removable brush is adjacently and concentrically to the connected shaft, opposite the handle. The tubular enclosure houses the removable brush and is positioned concentric with the connecting shaft, adjacent to the removable brush. Additionally, the tubular enclosure is slidably mounted to the connected shat, opposite the handle. The plurality of UV light sources kills or inactivates microorganisms on the removable brush. As such, the plurality of UV light sources is distributed about an inner surface of the tubular enclosure and is powered by the battery. The battery is internally mounted within the connecting shaft.
