Abstract: A tubular applicator handle having an applicator integrally formed on either end. The applicable integrally formed on either end may be a brush, foam pad, fuzzy ball or other similar or equivalent applicator, for applying a liquid, paste or powder. The applicator handle may or may not have a scribe or score line intermediate either end. The applicator handle may be broken along the score or scribe line forming two separate independent applicators. This greatly reduces waste and provides increased convenience to the user who can either use the double ended applicator or, if desired, two separate single ended applicators. A bendable portion is provided adjacent each applicator so that the angle of the applicator may be changed as desired. The present invention has particular adaptability in the dental field for applying dental materials, but may be valuable in other fields, such as electronics.

Abstract: A disposal brush includes a plate having a hub and a handle for manipulating the disposal brush secured to the hub. Depending from the plate is a support frame carrying elongated bristles thereon. The support frame, which is made at least in part from a resilient material, includes a central portion secured to the plate and side arm portions extending downwardly and outwardly from the central portion. The ends of the side arm portions are each bent inwardly. In use, when the bristles on the side arms engage the inner side wall of the disposal unit, the side arms are urged inwardly. The reaction of the resilient side arms is to urge the bristles thereon more firmly against the inner wall of the disposal unit so as to enhance the cleaning thereof. The bristles on the inwardly bent portions will engage the top wall of the disposal as the disposal brush is withdrawn from the disposal so as to help clean the same.

Abstract: A set (310) of lumen cleaning devices (310a, 310b, . . . ) is provided, with each consisting of a flexible shaft (312), a radial bristle brush (314) at one end of the shaft, and a swab (316) on the other end of the shaft. The brushes have particular brush diameters, may be stepped or tapered in diameter, and the swabs are dimensioned in conjunction with the maximum diameters of the brushes. The lumen of a medical device such as a catheter to be cleaned is first brushed with the brush end of a cleaning device selected to approximately match the lumen diameter. After brushing, the device is reversed, or preferably simply pushed through the lumen to be cleaned, and the swab end is used to remove any film remaining after the brushing. In a preferred method of cleaning, the brush end of the cleaning device is inserted into an end of the lumen to be cleaned, and pushed through only once, to avoid recontamination of the lumen by matter remaining on the brush.

Abstract: An applicator or brush having a twisted wire core and a bristle portion that has a square cross-section. The brush portion is formed from a plurality of plastic filaments.

Abstract: A brush for cleaning a pool table. The brush includes a handle with a first resilient support for supporting bristles and a second mounting support for supporting bristles. The first mounting support projects a first distance from the handle and the second mounting support projects a second distance from the handle. The first mounting support and the second mounting support are mounted on the handle in a spaced apart relationship to one another, and the distance of projection from the handle of the first mounting support is greater than the distance of projection from the handle of the second mounting support. Bristles are mounted on the first mounting support and on the second mounting support so that the brush may be used to brush between the bumper and the surface of a pool table as well as over the flat surface of the table and the entrance to the pockets on the table.

Abstract: The brush comprises a wand equipped at one end with a core (6) formed by two twisted branches (7,8) of metal wire. Between the turns of the branches, bristles (9) extending transversely with respect to the core, are trapped. At least a fraction of the bristles (9) of the brush has a transverse section in the shape of an L. The zone of the bristle (9) wedged between the turns of the metal core is flattened either through the effect of unfolding when the angle between the branches of the L opens or through the effect of folding when the angle between the branches of the L closes. This flattening reduces the rigidity of the bristle on the one hand and, on the other hand, preferentially increases the spacing of the bristle with respect to the helical ply formed by the turns. Thus, the flattening creates a disorganized arrangement of the section of the bristles.

Abstract: In a small brush, in particular an interdental brush, comprising a plurality of fibers or bristles (5) which are secured so as to protrude radially between two wire-type segments (1, 2) by twisting the latter, it is provided, with a view to improve the properties of handling and dental care, that the wire-type segments (1, 2) comprise at least one plastic fiber (3).

A semicircular slot is provided in the base member through which an extended fingernail may be accommodated. A reinforcement element secures the wire support and the bristles on the base member.

Abstract: A process for forming a twisted stem tool uses a specially designed clamping jaw fixture at the nose or bight portion of a half-round wire or cotter pin which helps to reduce the required clamping force and distribute that force over the entire wire-fill material interface. The jaws of the clamping fixture engage the outside of the nose over a substantial area, and in some forms actually bite into the wire or pin. After the twisting operation, the stem is placed in a swaging or coining press, and the stem beyond the fill material is reformed into a three or six-sided drive stem. The cold flow of the metal to form the flat sides locks the twisted half round wire or pin sections together so that the stem will resist unwinding if the tool is driven in a reverse direction. The coining of the stem providing flats provides a tighter confinement of the bundle of fill material at the stem, and enables a common three or six jaw Jacob's style chuck, for example, to obtain a more secure grip.

Abstract: A brush for applying make-up, particularly mascara, including a shaft provided at one end with a core (6) formed by two metal wires (7, 8) twisted together and having bristles (9) squeezed therebetween such that they extend transversely to the core axis. At least some of the brush bristles (9) have an L-shaped cross-section so that the portion of each bristle (9) which is squeezed between said twisted core wires is flattened either outwards when the arms of the L are pushed apart, or inwards when they are pressed together. In either case, the stiffness of the bristle is reduced and the spacing between the bristle and a wire helix formed after twisting is advantageously increased, whereby a random distribution of bristle cross-sections is achieved.
