Title: Making plastic toothbrush combating microorganism growth amongst its bristles
Inventor: RUEB FRITZ A
IPC: A46B11/00
Filed: 1998-04-24
Granted: 1999-08-05
Abstract: Before fusing holding ends (6) of bristles (3), they are coated with oligodynamic material (9). Welding or fusing together, then impresses and distributes this material into the softened or liquefied plastic. Preferred features: Oligodynamic material is coated on the holding ends of all bristle tufts. The ends are fused together and/or to the retention plate (4) or brush body. On the melting locations, at least locally, oligodynamic material is coated, penetrating into the bristles. The holding ends are uppermost with respect to the brushing ends (7). They lie in a plane for coating with e.g. suspension, solution or dispersion by painting, spraying, dropping and/or pressing. Bristles are held vertically, the ends to be melted lying horizontally. The coating is applied before or after fusing. Melted ends are softened or liquefied to the point that oligodynamic material penetrates the bristles towards the brushing ends. The holding ends are fused together. The holding plate with bristles is fitted into a recess (10) of the tooth brush body, forming an interchangeable head. Alternatively, to a toothbrush body fitted with bristles, a cover plate is applied.
