摘要:
A brush head, particularly a toothbrush head, may have a plurality of cleaning elements, in particular bristle tufts, which are anchored by an end section in a brush carrier, wherein the cleaning elements may be cast with positive engagement in blind-hole shaped retaining recesses. For producing such a brush head different cleaning elements may be placed successively or simultaneously in different mold cavities and may be over-molded using different plastic materials from which injection-molding sections of the bristle carrier are formed in the process. In doing so, a first cleaning element is over-molded in a first mold cavity using a first plastic material, while a second cleaning element is over-molded in a second mold cavity using a second plastic material.

An antibacterial cosmetic tool is produced by soaking a base material selected from fiber, yarn, pile fabric, animal hair, wig material, polyurethane sponge and NBR sponge into an aqueous solution containing (A) benzyl ammonium chloride compound and (B) naphthoquinone compound, after which the solution is heated to cause 0.1 to 5.0 percent by weight of (A) benzyl ammonium chloride compound and 0.1 to 5.0 percent by weight of (B) naphthoquinone compound to be adsorbed/contained to/by the material.
摘要:
Tooth decay is prevented by suppressing activity of intraoral fungi by providing on a toothbrush a product obtained by pulverizing shells having crystalline structural body of calcite type structure of calcium carbonate. A handle (2) or bristles (3) of the toothbrush (1) are formed of synthetic resin mixed with the product obtained by pulverizing shells having crystalline structural body of calcite type structure of calcium carbonate.
摘要:
The invention is intended to provide a brush which, while maintaining the superiority of animal hairs in paint holding and discharging performance, is free from the stiffening of the roots of bristles 4 and the expansion of the tips thereof even after its use for applying a water paint, and a method for manufacturing of this brush. To achieve the object stated above, the invention uses as its bristles 4 animal hairs whose pH count is adjusted to be neutral or alkaline.

A brush head, particularly a toothbrush head, may have a plurality of cleaning elements, in particular bristle tufts, which are anchored by an end section in a brush carrier, wherein the cleaning elements may be cast with positive engagement in blind-hole shaped retaining recesses. For producing such a brush head different cleaning elements, such as bristle tufts may be fused by heat and may be placed in a mold cavity to be over-molded.
摘要:
A rotary brush having a hub having a central bore, a plurality of wire knots extending radially outward from the hub and spaced apart from each other around an outer circumference of the hub, a thermosetting polymer encapsulating each wire knot, and substantially polymer-free spaces located between each adjacent pair of wire knots.
