<p>PROBLEM TO BE SOLVED: To easily remove dirt and plaque between teeth and around teeth by forming a plaque removing pick at the handle of a toothbrush and integrally molding them to use separately used things as a single thing to remove dirt, etc., by using with the toothbrush. SOLUTION: A pick housing pocket 2 and a vertical hole 3 into which the pick 5 is pushed and moved up/down are arranged at the tip of the tooth brush 1 and a groove 4 for allowing the pick 5 to slide is arranged at the side surface of the handle to form the toothbrush with plaque removing pick. The tip of the pick 5 is V-shaped, flat or round and a sliding knob 6 is provided at the lower part of the axis of the pick 5 to be incorporated in the tip of the tooth brush to operate the pick 5 with the knob at the time of using. The thickness of the tip part of the tooth brush is reduced a little and the axis of the pick 5 is inserted to its tip or adhere-fixed to fit a cap. At the time of using the toothbrush fixed with the pick 5, the knob 6 is pushed up with a finger to put out the pick 5, whose length is properly adjusted.</p> |
