Definitions

  • the present invention relates to toothbrushes for massaging gums as well as cleaning teeth.
  • toothbrushes comprise a handle portion and a head portion.
  • the head portion generally contains a pattern of holes on one side into which are inserted bristles. Tufts of bristles are conventionally secured in the holes by means of short anchor wires.
  • the handle portion is attached to the head portion of the toothbrush, a thinner neck portion sometimes being provided.
  • the handle generally lies in the same general orientation as the head although it may be angled from the head as desired.
  • a toothbrush It would be desirable for a toothbrush to be of a design which can be effectively manipulated in use to achieve efficient and effective cleaning of the teeth and massaging of the gums. Toothbrushes have been designed with a great many varying grips in an effort to facilitate holding the toothbrush in a suitable manner for brushing the teeth. In general, however, such attemps to provide improved grip have resulted in toothbrushes which can be held firmly in one position but not manipulated easily into other positions. It is generally accepted that a desirable cleaning action is up and down rather than across the tooth surface.
  • a toothbrush for massaging gums as well as cleaning teeth comprising a head portion having bristles for massaging gums and cleaning teeth, and an elongated handle extending from the head portion, the handle having a barrel-shaped grip portion shaped to facilitate rolling of the toothbrush between the thumb and forefinger during use of the toothbrush, and an extension portion extending from the grip portion adapted to fit across the palm of the hand in use and including a stabilizing portion for engaging the hand and assisting in the control of the rolling action during use of the toothbrush.
  • Embodiments of the invention can provide, with advantage, the facility of rolling the toothbrush to achieve the desired preferred action of up and down cleaning.
  • the bristles will extend substantially away from the head generally in a first direction and the handle will extend substantially at right angles to the first direction.
  • the extension portion extending from the grip portion may be generally spatula-shaped and in particular may increase in width towards the free end of the toothbrush.
  • a preferred feature of the toothbrush is the inclusion of a cut-away portion on the back of the handle (i.e. the side opposite that containing the bristles) at the junction of the barrel-shaped grip portion and the extension portion in order to provide a suitable position for the second finger, whilst the barrel is gripped between the thumb and forefinger.
  • the toothbrush will be provided with a second cut-away portion on the front of the handle (i.e. the side containing the bristles), adapted to allow in the alternative, a conventional grip to be exercised by placing the forefinger on the first cut-away portion and the thumb on the second cut-away portion.
  • a second cut-away portion on the front of the handle (i.e. the side containing the bristles), adapted to allow in the alternative, a conventional grip to be exercised by placing the forefinger on the first cut-away portion and the thumb on the second cut-away portion.
  • another pair of cut-away portions third and fourth formed in the sides of the handle at the junction of the barrel-shaped portion with a narrow neck portion.
  • a fifth cut-away portion may also be provided on the front of the handle at the junction of the barrel-shaped portion with the narrow neck portion.
  • An alternate gripping facility for fine control where the toothbrush is held in the place in which it is conventionally gripped, is thereby provided when the thumb rests on this fifth cut-away portion and the forefinger rests on the back of the neck opposite the cut-away portion.
  • the barrel-shaped portion will be tapered and may be provided with suitable texture to facilitate control whilst rolling the brush between the thumb and forefinger.
  • the toothbrush shown in the drawings comprises a set of bristles 3 attached to the head portion 1 of a moulded plastic handle 2.
  • the handle 2 includes a narrow neck portion 4 attached to the head portion 1 and leading to a barrel-shaped portion 5, from which a spatula-shaped portion 6 extends.
  • the barrel-shaped portion 5 is oval in cross-section having its major axis substantially at right angles to the direction in which the bristles 3 extend from the head portion 1.
  • the spatula-shaped portion 6 widens from its junction with the barrel-shaped portion 5 towards its free end.
  • FIG. 6 there can be seen a first cut-away portion 7 on the back of the handle adapted to support the second or middle finger when the barrel-shaped portion 5 is gripped between the thumb and forefinger.
  • a second cut-away portion 10 is also formed on the opposite side of the handle at the junction of the barrel-shaped portion 5 with the spatula-shaped portion 6. The toothbrush may be gripped conventionally by placing the forefinger on the first cut-away portion 7 and the thumb on the second cut-away portion 10.
  • a texture is provided on the surface of the barrel-shaped grip portion 5 by means of raised dimples 8 and a suitably roughened surface portion 9.
  • cut-away portions 11 and 12 on either side of the handle at the junction of the narrow neck portion 4 and the barrel-shaped grip portion 5. These cut-away portions 11 and 12 co-operate to provide alternate gripping for fine control of the toothbrush in a plane substantially at right angles to the plane in which the handle is conventionally gripped.
  • a fifth cut-away portion 13 is provided on the front of the handle the junction of the narrow neck portion 4 and the barrel-shaped grip portion 5. This cut-away portion 13 and the back of the neck 14 co-operate to provide alternate gripping for fine control of the toothbrush in the same plane in which the handle is gripped conventionally.
