A toothbrush having a handle and a rubber-like brushing structure having a plurality of brushing projections and mounted on the forward part of the handle is further provided with a rigid frame member surrounding the side surface of the brushing structure and engaged with the latter in a projection-and-recess relation, the frame member being bonded to the handle for indirectly securing the brushing structure to the handle, and the "hardness" in operation of the toothbrush, i.e., the brushing pro...

A toothbrush having an elongate handle with an enlarged base end capable of supporting the toothbrush in an upright position and being hollow for storage of the bristle head or the like therein, includes an elongate shaft fixed at one end to the base and projecting axially therefrom. A tubular sleeve is axially slidable on the shaft and the shaft has bristle head retaining structure thereon for retaining a bristle head on the handle at the end thereof opposite the base end. The sleeve is normall...

A toothbrush which has a brush handle, a head on one end of the handle and a resilient, preferably multicellular pad fixed on the brush head. The pad has a concavity of a relatively large area across the pad in the area halfway between the ends of the pad on the upper surface, to form two protrusions on the opposite sides of the concavity. Each protrusion has at least one upside projection thereon substantially of the form of a triangular prism with the lateral edges extending in the lateral dir...

A toothbrush which comprises an elongated handle including a U-shaped head coaxial with a front end of the handle. The head is provided with two opposite bristles-carrying portions located to opposite sides of an axis of the head and each of the portions has a front edge which is inclined at an acute angle to the axis. The toothbrush further includes a plurality of bristle tufts which are spaced from each other inwardly from the bristle-carrying portions and are arranged in a first plurality of ...

A toothbrush comprising a brush head and a handle, the brush head carrying three rows of bristle tufts which form a generally T-shaped pattern when viewed from above. A first and second row of tufts extend angularly toward each other and intersect in a plane which runs generally parallel to the longitudinal axis of the brush. A cross row of tufts at the end of the brush head inclines toward the other tufts to from the T-pattern. The handle is specially contoured near the brush head to facilitate...

A toothbrush comprising a single-piece mounting with handle and brush carrier formed by a standard level surface but provided with a profiled slit forming a resilient connecting tongue allowing the brushes to pivot and oscillate according to the pulses transmitted ensures the inter-dental cleansing and building up the base of the teeth.

A toothbrush head comprising three widthways adjacent sections in which the tip end of the middle section is enlarged into a bristle-carrying tip pad, there is an intermediate bristle-carrying pad between the tip pad and the base end of the head, with narrow link regions between the pads and the intermediate pad and the handle. The sections are connected to the toothbrush handle by flexible necks. The bristle distribution of a multi-section toothbrush head is thereby optimized.

A toothbrush with a cleaning zone on which tooth-cleaning elements are arranged, which are pressed against the teeth during cleaning with a cleaning force, and with a deformable element by which the cleaning zone is can be adapted to the shape of the tooth surface by the cleaning force, where the deformable element has at least a first flexible wing facing towards the cleaning zone and a second such wing facing away from the cleaning zone, and also at least one guide element, and where the first...

A toothbrush head having elastomeric oral hygiene parts in the form of elastomeric strips aligned non-perpendicular to the length direction of the head. Preferably adjacent pairs of strips are linked to form a strip of "V" cross section. Preferably the head comprises flexibly linked segments and is flexibly linked to the toothbrush handle.

A toothbrush includes a handle and a head. The head is in the form of a peripheral frame having an open central area. A plurality of cleaning element carrying support members are mounted across the frame over the open central area to form an open lattice pattern having through holes to facilitate the cleaning of the head. The cleaning elements are bristles laser welded to the support members.
