Abstract

An articulate toothbrush particularly suitable for integral molding having a handle with an elongate grip and a support section extending from the grip to the brush head with an arch shape. The arch has a leg that returns toward the longitudinal axis of the grip at an acute angle to a connection with a brush head. The brush head has a longitudinal axis and terminates along that axis in a heel in the direction of the grip of handle and in a toe in the direction away from the grip. The top of the brush head is proximal to the distal leg of the support and the bottom of the brush head which is distal to the distal leg, has bristles depending therefrom. The distal leg of the support is connected to the top of the brush head at a medial position along the brush head longitudinal axis by a flexible plastic hinge. The hinge is narrow in the direction parallel to the brush head longitudinal axis and wide in the transverse direction, relative to its thickness in the parallel direction to thereby create a hinge axis of rotation generally normal to longitudinal axis of the grasp and to the longitudinal axis of the brush head for relative pivotal movement between the brush head and the handle over a desired acute angle arc.
