The wire element is connected to the second end at a first terminating point and a second terminating point with a looped wire portion extending therebetween. The looped wire portions of the three brush members are disposed on the base member to thereby form a brush gap configured to accommodate a wheel lug nut.

    Abstract: A cosmetic applicator assembly, which includes a polymeric brush and a twisted wire brush. Specifically, the polymeric brush comprises an elongated polymeric core and multiple polymeric tines protruding from the elongated polymeric core. The elongated polymeric core comprises a first polymeric material of a first tensile modulus, while at least some of the polymeric tines comprise a second polymeric material of a second tensile modulus that is smaller than the first tensile modulus. The twisted wire brush comprises a metal wire core and multiple bristles protruding from the metal wire core. The elongated polymeric core of the polymeric brush is complementarily engaged with at least a portion of the metal wire core of the twisted wire brush to form the cosmetic applicator assembly. The polymeric brush of the present invention is preferably formed by a bi-injection molding process.

    Abstract: The present invention relates to a cleaning device comprising cleaning means and a frame body. The frame body is provided with a plurality of connecting holes, wherein each connecting hole is constituted by a larger diameter hole and a smaller diameter hole, such that the twisted cleaning means is folded to stuff through the connecting holes from the larger diameter hole to the smaller diameter hole. The folded twisted cleaning means then is pulled back so as to bind the twisted cleaning means in the frame body.
