Title: Tooth brush
Inventor: MORITA NORIKATSU
IPC: A61C17/22
Filed: 1995-02-24
Abstract: PURPOSE: To provide a tooth brush by which teeth can be brushed always with a proper force to prevent the gum from being damaged by forming a curve portion having a cut portion in which the cut faces come into contact with each other in the tooth brush main body. CONSTITUTION: A whole handle of a tooth brush is made of an elastic resin. A curve portion 2 having a cut 1 in which the cut faces are in contact with each other is provided between a brush 3 and a grip 4. When an excessive force is applied, the faces of the cut 1 are deviated, a click sound is generated, and a user's hand certainly feels the deviation indicative of the excessive force. When the faces in contact with each other are deviated, the faces return to the original state by elasticity of the curve portion 2 by weakening the force applied. The excessive force causing the deviation of the contact can be variously set by adjusting the size and shape of the contact at a designing stage.
