TOOTHBRUSH WITH FREELY MOVABLE HEAD

摘要

PROBLEM TO BE SOLVED: To reduce time and labor necessary for tooth brushing by implanting brushes onto the upper bottom face of a brush base and providing the lower bottom face of the brush base with a rotary shhere and forming the tips of a U-shaped lug to form nearly spherical spoons and further arranging the recessed faces so as to face each other. SOLUTION: Brushes are implanted on the upper bottom face of a parallelepiped or columnar brush base A1 and a rotary sphere A2 is disposed at the center of the lower bottom face of the brush base A1 or in the vicinity thereof. The front tip of a U-shaped lug B is formed so that nearly spherical spoon-shaped recessed faces face each other to shape a pinching part B1. A plurality of fixing conical projections B2 are formed on the concave parts of the pinching part B1. The rotary sphere A2 of the head A is held by the concave parts of the pinching part B1 from both sides to fit the head A to the lug B. A projection B3 is formed at one side of the lug B to open or close the pinching part B1 at the inside near the front end of the lug B.
