IPC: A46B3/22
Filed: 1994-02-03
Abstract: PURPOSE: To indicate minimum brushing time by its color change by constituting a head and/or bristles of dispersed thermochromic materials. CONSTITUTION: A head and/or bristles are constituted of dispersed thermochromic materials capable of imparting a color change at a time interval adapted to proper brushing time. A (handle + head) of a toothbrush is formed by injection molding together with the materials. It can be devised so that the color change is caused in a minute or two minutes or at optional other time interval only by controlling a parameter and a manufacturing method of the materials. A head of the toothbrush stays in a mouth environment, and an environmental wall is close to 36.5 deg.C. The materials are exposed to this temperature by a uniform method, and show various colors at a new temperature by abandoning a color possessed by them at a room temperature. A user recognizes this color change, and understands that teeth are brushed for a proper minimum time when this is caused. After brushing, the brush gradually returns to the room temperature, and becomes a former color.
