Abstract
A manually operable toothbrush which has been specifically designed in shape to facilitate cleaning of the mandibular lingual anterior surface of the arch of the lower teeth and the maxillary anterior palatal area of the arch of the upper teeth. The brush includes a rigid handle and a rigid head with the head being mounted at an angular relationship relative to the handle. The interior surface of the head has mounted thereon a series of bristles. These bristles are located in a curved pattern and also in a tapered form which facilitate access to the surfaces of the teeth upon which the toothbrush is to be used. The shape of the head and the angle of the head to the handle can be adjusted according to individual desires.
Claims4
A toothbrush comprising:
- an elongated handle having a first longitudinal center axis;
- a head attached to one end of said elongated handle, said head being elongated, said head being constructed of sheet material, said head having a second longitudinal center axis, said second longitudinal center axis intersecting and being located at an inclined angle relative to said first longitudinal center axis, said head having an exterior surface and an interior surface, said interior surface forming an obtuse interior angle with said first axis, said head having an outer free edge;
- a bristle section formed of a plurality of tufts attached to said interior surface of said head, said bristle section extending from said outer free edge to directly adjacent said elongated handle, said bristle section extending substantially totally across said head terminating in free outer ends, said bristle section having a brushing plane defined by the free outer ends of said bristle section, said brushing plane being in a shape of a segment of a sidewall of a cylinder, said bristle section being tapered resulting in said tufts being longer in length at said outer free edge, whereby said toothbrush can be used effectively to clean the mandibular lingual anterior surface of the arch of the lower teeth and the maxillary anterior palatal surface of the arch of the upper teeth of a human;
- and
- said head being bowed forming a concavity in said exterior surface, said concavity extending transversely across said head with said concavity having a third longitudinal center axis, said third longitudinal center axis coplanar with said second longitudinal center axis, said second longitudinal center axis coplanar with said first longitudinal center axis.
