Definitions

  • the invention relates to toothbrushes having a medically advantageously designed brush head and to methods for producing such toothbrushes and to their use.
  • US 6 554 614 describes a toothbrush having a central hub and a plurality of bristles mounted thereon, which i) converge towards each other and ii) when viewed in their entirety, have a tapered configuration when rotated.
  • the brush head thus shows in use an outwardly curved (convex) contact surface.
  • US 2003/0048533 describes a toothbrush with a flexible elastic head which carries bristles. In this case, the free ends of the bristles in the load-free state along the longitudinal or transverse axis of the toothbrush on a generally concave profile.
  • WO 2005/006915 describes, inter alia, a toothbrush with bristles of different lengths and thicknesses, the contact surface as a result being "serrated.”
  • the above-mentioned publications address the problem of insufficient cleaning effect of conventional toothbrushes
  • the problem of cleaning the interdental area is also addressed and the documents address, at least in part, the problems of ease of manufacture, toothbrush cleaning and ease of use.
  • the object of the invention is now to provide a toothbrush with a brush head according to the preamble, whose improved construction leads to an improved cleaning result.
  • a good cleaning result should be achieved with low pressure on the teeth. Furthermore, the cleaning result should be improved, in particular in the area of the interdental spaces.
  • a toothbrush is to be made available in which the user an optimal control is made possible, so that the teeth can be very consciously and selectively cleaned.
  • the manufacturing techniques and the structure should be simple and the manufacturing cost of the toothbrush low.
  • a toothbrush consists of a brush head from which protrudes on one side a cleaning structure and a handle which is connected to the head via a neck.
  • Brush head is understood below to mean the area that carries the cleaning structure.
  • the grip area is the area that is gripped by the user in the application.
  • the neck is the area between the head and the handle.
  • the brush head (1) (or “head”) of the brush according to the invention is inelastic, indicating that no deformation of the brush head is observed with the brush force normally used (1-10 Newton, preferably 2-4 Newton) Inelasticity is achieved by suitable choice of material and thickness and can be found in the description / examples
  • Cleaning structure (4) refers to the elements used to clean the teeth, such as bristles, bristle tufts, soft-elastic elements or combinations
  • the cleaning elements are preferably arranged parallel to each other
  • the cleaning structure consists of one or more bristle tufts, more preferably a bristle tuft.
  • the surface (5) of the cleaning structure is understood to be the surface which in use is in contact with the teeth.
  • the surface of the cleaning structure is concave and is defined by the radius of curvature r.
  • the radius r can either be identical for the longitudinal and transverse directions (giving a spherical surface) or different values (resulting in an ellipsoidal surface). Preferred is a spherical surface.
  • the radius r of the ball which describes the curvature of the concave surface of the cleaning structure, is in the range of 10 - 500 mm, preferably in the range of 15 - 250 mm, most preferably in the range of 25-150 mm.
  • the concave surface of the cleaning structure is created by the blank and / or the attachment and / or the shape of the front surface of the head (see Fig.2).
  • the length of the bristle tufts is different and arranged to provide a concave surface.
  • bristles / bristle tufts of equal length are introduced into the head at different depths, resulting in a concave surface.
  • the same length bristles / tufts are introduced with the same depth in the head; wherein the front surface of the head itself is concave, resulting in a concave surface.
  • the front surface (6) of the head region is understood to be the surface on which the cleaning structure, in particular bristles and / or soft elastic elements, is attached.
  • the front surface is 3 - 180 mm2, preferably 7 - 80 mm2, most preferably 12 - 50 mm2.
  • the shape of the base surface from which the cleaning structure protrudes may vary, preferably it is round or ellipsoidal, more preferably round.
  • Head can be done with the usual, familiar to those skilled techniques. So bristles can be attached either individually or in tufts in the head. The attachment can be done for example by molding with plastic compound.
  • the plastic compound for encapsulation may be identical to the material used for the head. Alternatively, this plastic mass of elastic Mate- material (7), so that there is a resilient storage for the Reiniguns Modell. If the cleaning structure consists of bristle tufts (n), this can also be secured by means of anchors in the head.
  • the dimensions of the toothbrush according to the invention largely correspond to the dimensions of commercially available toothbrushes; for the surface (5) and the front surface (6), however, the information is given in this description.
  • the handle, head and bristle materials are generally known to those skilled in the art.
  • Handle and head can be made of the same material; suitable materials are wood-based materials and plastics. Preference is given to plastics based on casting resins, polyamide and polypropylene.
  • the handle, neck and head are made of the same material.
  • the object of the invention is applicable both to manually operated toothbrushes and to electrically operated toothbrushes (in particular those having an oscillating round toothbrush, as are known, for example, from EP 1 138 222 A2 or from EP 0 765 642 A2).
  • the toothbrush can therefore be a manual toothbrush, in which the hand must perform all cleaning movements mechanically; but it can also be an electrically operated toothbrush with a about her longitudinal axis back and forth swinging brush movement or an oscillating brush movement. According to the present invention, manually operated toothbrushes are preferred.
  • the subject matter of the invention can also be applied to modular toothbrushes. These are understood to mean toothbrushes in which the head and handle are releasably connected to one another. This makes it possible to use different heads on the toothbrush to accommodate different difficult cleaning situations.
  • the connection of the head and handle can be done for example by conventional plug screw or bayonet connections.
  • EP 1163861 discloses a possibility for a suitable connection system.
  • the head, neck and handle of the toothbrush are made in one piece.
  • Areas can be combined with each other as desired. Furthermore, individual embodiments or areas can be omitted.
  • Fig. 1 a toothbrush with (1) head; (2) neck; (3) handle; (4) cleaning structure (here as bristle tufts); (5) surface of the cleaning structure; (6) front surface of the head and
  • Fig. 2 shows the section through a brush head of the brush of Fig. 1, wherein (1) head; (4) cleaning structure; (5) surface of the cleaning structure; (8) tooth; (r) radius of curvature of the surface; (t) Depth of the cleaning structure are shown in the head.
  • the invention relates in a second aspect to a method for producing the toothbrush according to the invention, comprising the steps (method A) attaching the cleaning structure in the brush head and then shaping / shortening / trimming the cleaning structure to obtain a concave surface; or (method B) production of a cleaning element with a concave upper surface and attachment to the brush head; or (Method C) Attachment of the cleaning element to a concave brush head.
  • the brush of the invention is prepared by method A by cutting bristles by means of a spherical cutting tool.
  • the invention relates to the use of the toothbrush according to the invention for cleaning natural teeth and artificial teeth, such as dental implants, bridges or dentures.
  • the cleaning of artificial teeth is relevant both during manufacture and during use by the user.
  • the cleaning of artificial teeth can therefore also take place outside the body.
  • the cleaning of artificial teeth primarily serves aesthetic purposes.
  • Example 1 Preparation and Use of a Toothbrush: A toothbrush, total length 18 cm, with a circular bristle tuft, diameter 0.5 cm, is prepared by known methods. Subsequently, the bristle tufts are processed by means of a diamond-studded ball so as to trim the toothbrush-side surface to a concave shape.
  • the toothbrush according to example 1 causes the user (only to force it) to make small movements with little force, and optimally adapts to the buc- cal surfaces of the teeth (these are convex) by means of the concave brush field
