Definitions

  • This invention relates to the field of tooth cleaning implements, and specifically toothbrushes.
  • An object of the present invention is to provide a toothbrush which has an efficiency comparable to that of motorised toothbrushes in spite of its manual operation.
  • a further object is to provide a toothbrush of cost comparable to more traditional toothbrushes.
  • a further object is to provide a toothbrush which can be used either in the conventional manner or in a manner which enables it to exert the cleaning action typical of motorised toothbrushes and of small spiral brushes.
  • a further object is to provide a toothbrush which can have differing abrasive action by virtue of bristles of different flexibility.
  • a further object is to make readily available and to hygienically protect a toothpick able to remove food residues which cannot be removed from the tooth interstices by conventional bristles.
  • the bristles 4 or 5 can obviously be of natural or artificial type. As can be seen on the drawing, they are fixed to the two specific faces of the flat stem 6 to thus form a double toothbrush but provided with only one operating handle 1.
  • bristles 4 and 5 are different in terms of hardness, thickness or quality.
  • hard bristles can be positioned on one side, whereas on the other side softer bristles suitable for delicate gums can be used. This is particularly useful as the type of bristles used can be changed-over immediately, without having to use another toothbrush.
  • the bristles 4 and 5 could however also be of equal flexibility, the two bristled surfaces, orientated in different directions, then allowing other properties or functions to be utilised which do not necessarily depend on this difference.
  • One of these is to allow the tips of all teeth to be cleaned simultaneously. This is done by sliding said toothbrush along the top of the dental arch while closing the jaw sufficiently for this purpose, so simultaneously cleaning the tips of the teeth of the lower arch and the tips of the teeth of the upper arch.
  • a further property consequent on the opposing orientation of the bristles is to allow rapid tooth cleaning action by sliding the bristles in a single vertical direction. This is done by rotating the handle 1 by the opposing movements I and P using the forefinger and thumb. Whereas in the case of traditional toothbrushes vertical tooth cleaning movements require a tiring movement of the entire hand to be made, in the case of the toothbrush according to the invention this is done by simply rotating the roundish section of the handle 1 between the forefinger and thumb.
  • Said rotation can be made either always in the same direction or in alternate directions, but in either case without effort because the moving mass is represented practically only by said toothbrush and the two fingers used, the mass thus resulting in negligible inertial forces.
  • the rotation speed R depends not only on the force used but in particular on the diameter of the handle 1.
  • the smaller this diameter the greater the number of revolutions it undergoes for the same linear movement (I, P) of the fingers.
  • the smaller this diameter the greater the force required on its surface to overcome the reaction moment developed by the engagement of the toothbrush with the inside of the mouth, and thus the greater the possibility of the fingers slipping on the handle 1.
  • either the handle diameter can be suitably chosen or the handle surface can be appropriately shaped.
  • the handle can have a circular cross-section and incorporate longitudinal grooves or projections (Figures 1 and 2), or can be of polygonal cross-section as shown in Figures 4 and 5, or again can have other cross-sections or surfaces of different appearance but satisfying the requirement of providing sufficient friction for the operating grip of the fingers.
  • a further characterising aspect of the present invention is a handle 1 provided with a cavity 7 for housing the body of a toothpick 8. Said toothpick is provided with a base 9 designed not only to allow its edges 10 to fit securely into the housing 7 but also to enable it to remain in an erect position by virtue of its large base surface 11.
  • toothpick is an implement which makes contact with internal parts of the mouth, its vertical positioning advantageously prevents it becoming a vehicle for microbes normally found on touching surfaces.
  • Said toothpick indicated in point form on the drawing, can however have a flat flexible end resulting in high bending strength in a given direction, although be of small thickness, so that it can be inserted between two teeth to perform the action of conventional dental floss.
  • a cross-sectional reduction 12 between the holding region of the handle 1 and the bristled end 3 there is a cross-sectional reduction 12 so that the pressure exerted on it by the lips does not generate obstacles to its rotation.
  • the ideal reduced cross-section is round, but other smoothly connected reduced cross-sections are suitable, without leaving the scope of the inventive idea.
