摘要： PURPOSE:To improve the effect of tooth-brushing by providing recesses and projections only at the tip portions of plural filaments that are planted at the head of handle of a toothbrush and form brush bristle, butting the filaments against every part of teeth at right angles. CONSTITUTION:Only the tip portion 3 of brush bristles 2 consisting of filaments planted at the head of handle 1 of a toothbrush is formed into a recessed and projecting state. For example, a grinding belt is butted against the tip portion 3 of the brush bristle 2 to form recesses and projections at a right angled to the handle axis and in parallel with the handle axis at part of or the whole perimeter of the tip portion 3, or projections are formed at the tip portion 3 of the brush bristle 2. As a result, the tip portion 3 of the brush bristle 2 butts against every part of teeth at right angles at all times regardless of how the handle 1 is held, and the surface of teeth and spaces between teeth are correctly cleaned.

摘要： PURPOSE:To obtain a soft wiry material, having high friction on the surface and high safety without breaking at a stroke. CONSTITUTION:This soft wiry material is obtained by coating the periphery of fibrous wiry materials such as twisted yarn with a soft elastic material such as rubber, twisting the plural wires, providing one soft wiry material and then coating the periphery thereof with a soft elastic material such as the rubber. Since there are unevennesses on the surface, friction with the objective material is high, a label or an adhesive on the surface of a container, merchandise, etc., is strongly scraped off when used as a brush wire. The wiry material can be prevented from shifting its position from a baggage when used as a packing rope. Thereby, the baggage can surely be held.

摘要： PURPOSE:To enable the effective removal of the bacterial plaque even if the tips of brush hair are not always pressed perpendicularly to the teeth by using filaments having ruggedness on the surfaces as the brush hair. CONSTITUTION:The filaments 10 are formed to square, approximately star, starfish, hexagonal or other sectional shapes. The brush hair 14 intrudes into intra-tooth parts 19 when the brush hair 14 is pushed approximately perpendicularly to the tooth surface on which the teeth 18 line up. The brush hair 14 intruding into the intra-tooth parts come into contact with the adjacent surfaces A, B or C, D of the respective intra-tooth parts or the body parts E of the teeth. The body parts of the brush hair 14 slide the respective adjacent surfaces A to B when a head part 16 is vertically moved in this state. The ruggedness on the surfaces of the filaments and the square parts, etc., of the outer peripheries thereof act to scrape off the dental plaque of the adjacent surfaces and, therefore, the bacterial plaque is efficiently removed.

摘要： PURPOSE:To provide a washing device which is capable of automatic cleaning of cooling utensils, e.g. meat roasting iron plate, having the surface contaminated with fats and oils by making use of the brushing action of a roller brush and which is excellent in durability and operational efficiency. CONSTITUTION:A roller brush 2 is of a new structure having an excellent durability and made of a mixture of resin material and abrasive grains. A holder 1 for setting thereon an object 10 to be cleaned is automatically reciprocally movable within a predetermined range relative to a rotatable roller brush 2 and its reciprocal movement is accompanied by an automatic control of starting and stopping the feed of water sprinkling and of rotating and stopping the roller brush 2.

摘要： PURPOSE:To provide an interdental brush having no rupture at bent sections even when fine wires are used, no falling off of brush hairs, and improved durability. CONSTITUTION:A film material layer 2 made of thermoplastic resin having a low melting point is provided around a linear core material 1 made of a ultra-elastic alloy, many filament-like brush hairs are linearly protruded outward and planted on the film material layer 2, the film material layer at the base sections of the brush hairs 3 is fused and solidified to integrally fixing the brush hairs 3, and an interdental brush having a high bending fatigue characteristic can be manufactured. Even when fine wires having a good passing property between teeth are used, no rupture is generated by the repeated bending deformation in use. Since the brush hairs 3 are integrally fixed to the film material layer 2, a cleaning action can be satisfactorily performed, and the planting strength can be sharply improved.
