A toothbrush is provided with a base and handle having a flexible neck portion in order to clear the lip and chin. A stepped neck portion is provided whereby the thickness of the flexible neck portion is substantially less than the thickness of the base, the length of the neck portion being substantially greater than the length of the base, the width of the entire neck portion is substantially less then the width of the base, and the entire thickness of the neck portion is less than the entire width of the neck portion. A stepped end face is provided at the end of the base and the surface of the base is disposed at an angle facing away from the handle front face.
The invention features a so-called transversal toothbrush to ensure greater brushing efficiency between the teeth and at the neck level of the teeth. It is characterized in that the direction of the handle (2) is preferably perpendicular relative to the longitudinal direction of the brush body (1). The handle is either connected fixedly with the brush body but with a deformation region (6) for transversal or longitudinal use, or it is mounted movably on the brush body. A mechanism for blocking it in position are provided on the brush body by a truncated cone (10) topped by a shaft (13) and opposite, on the handle, by an apertured hood (16) comprising two lugs (17) and part of a cylinder (18).
A toothbrush for cleansing the teeth, including a unitary body having a handle with a grip portion having concave indentations formed on a surface thereof, and a neck portion formed with the grip portion and positioned at an obtuse angle thereto. A cross-shaped head is formed with one end of the neck portion and includes a first head member positioned in axial alignment with the longitudinal axis of the handle. A second head member is formed with the first, and has a longitudinal axis positioned perpendicular to the longitudinal axis thereof. Each of the head members includes a preselected transaxial width, and rounded corners defined by respective curves having combined radii of at least seventy-five percent of the transaxial width of the head member. A multiplicity of bristles are attached to both head members and define an enlarged cleaning surface area sufficient to simultaneously engage the upper and lower teeth during brushing.
A toothbrush for cleansing the surfaces of the teeth and any orthodontic appliances positioned thereon. The toothbrush includes an elongate handle. A head is carried on one end of the handle and includes first and second intersecting head members carrying cleaning elements thereon. The first and second head members define at least three distinct and diverging head segments for providing an enlarged cleaning surface area sufficient to simultaneously engage the upper and lower teeth during brushing.
