Definitions

  • the invention relates to a toothbrush with a brush head made of plastic and bristles made of plastic embedded individually in the brush head, which are arranged at a short distance from one another.
  • Toothbrushes of this construction are known (WO 96/27 308). Compared to conventional toothbrushes, in which the bristles are combined into individual bundles and several
  • the aforementioned toothbrushes have the advantage that the bristle ends, which are primarily effective during cleaning, are evenly distributed on the effective brushing surface, so that with the dentistically recommended cleaning method from red to white, i.e. an essentially vertical guide the brush is cleaned (teeth) or massaged (gums) with a superimposed, slight swiveling movement, while the bristle trimmed area is gently massaged, while toothbrushes with the usual bundle trimmings leave certain areas of tooth flesh and / or teeth untreated.
  • the bending stiffness of the bristles is, among other things, the bending stiffness of the bristles.
  • a bundle it is essentially determined by the bundle length and the packing density of the bristles in the bundle and the diameter of the individual bristles, the latter having the least influence, since the bristles in the bundle are supported against one another, so that the bending rigidity of the bundle is reduced is many times larger than that of the individual bristle.
  • the bending stiffness is additionally influenced by the distance between the bristles and, due to the distance, the influence of the bristle diameter is more pronounced than with bundles.
  • the flexural rigidity can be varied in fine gradations, in particular finer gradations, than the gradations "soft”, “medium” and “hard” that were previously common with toothbrushes. Due to the shorter embedding length of the individual bristles compared to bundles, the overall height of the brush head can be reduced.
  • the care and cleaning status of the molars, especially on the outside of the teeth (distal), is far worse than in the anterior region. This is related to the essential poorer accessibility of the molars, the often cramped conditions in the distal space, which can take on serious forms if there are anomalies in the dentition, and the increased sensitivity and irritability in the distal area of the molars, which, depending on how the toothbrush is guided, can lead to nausea. Even the dentistically recommended cleaning method red / white can only be carried out inadequately in the molar area due to the cramped conditions. Due to the greater pressure load, injuries to the gums and lesions of the tooth enamel are more likely in this area.
  • the invention has for its object to provide a toothbrush that allows perfect use of the red / white method in the molar tooth area and in particular enables equally good cleaning of the molar teeth in the distal area.
  • Claim 1 (WO 96/27 308) this object is achieved according to the invention in that about 400 to 800 individual bristles per cm are arranged on the brush head on the area provided with bristles and de resulting height from the free length of the individual bristles and the thickness of the brush head the toothbrush is between 6.5 and 11mm.
  • the toothbrush designed according to the invention is initially distinguished by an extremely low overall height, which is formed from the free bristle length and thickness of the brush head. It is between 6.5 and 11mm, while with conventional toothbrushes it extends up to 20mm. Because of this flat design, the distal area is also to clean the molars easily, the red / white method can be used there and the pressure can only be determined by the user, since the inside of the cheek itself no longer exerts any pressure on the toothbrush.
  • the number of individual bristles at a short distance which is also provided, allows the bending stiffness to be set to the desired degree or to be graduated in a user-specific manner, despite the shorter length of the individual bristles.
  • microfibers are applied to the brush head in addition to the usual bristle bundles. These microfibers are limp and therefore extremely soft, so that they can have no mechanical effect on the dental plaque. At most, they have a polishing effect. Let also such microfibers do not attach themselves directly to the brush head due to their extremely small diameter.
  • the design according to the invention can be used with the same effects both for manually guided toothbrushes, which thus have a handle attached to the brush head, and for electrically operated toothbrushes, in which the brush head is attached to a drive.
  • the free length of the individual bristles is preferably between 5 and 9.5 mm and the thickness of the brush head between 1.5 and 3.0 mm.
  • the small thickness of the brush head is possible in particular in that the individual bristles must be embedded in the plastic of the brush head over a short length in order to achieve the necessary pull-out strength.
  • the design according to the invention also allows the effective brushing surface to be given a topography in which the free ends of the individual bristles lie on a continuously or discontinuously curved envelope surface whose distance from the surface of the brush head varies by up to 3 mm.
  • a preferred embodiment of the toothbrush according to the invention is characterized in that the overall height of the toothbrush is approximately 8.5 mm with a free length of the individual bristles of 7 mm and a thickness of the brush head of 1.5 mm, approximately 600 bristles per cm being provided.
  • the individual bristles are embedded in the plastic of the brush head in the injection molding process by encapsulating their attachment-side ends with the plastic.
  • the inventive design also gives the possibility that the brush head on its bristle side has convex curved surface and the individual bristles are arranged approximately perpendicular to the surface.
  • the back of the brush head can also be concavely curved, so that the brush head has approximately the same thickness over its entire length, without the brush head becoming hard as a board through this profile.
  • the individual bristles standing vertically on the surface preferably have the same length.
  • the embedding length of the attachment-side ends of the individual bristles is preferably less than 10 times of the diameter of the bristle.
  • the embedding length for the above-mentioned diameter range from 0.125 to 0.225 mm is a maximum of 1.25 to 2.25 mm.
  • Figure 1 is a plan view of the bristle field of a toothbrush
  • FIG. 2 shows a side view of the toothbrush according to FIG. 1;
  • Figure 3 shows an enlarged section of a
  • Figure 4 is a view of the representation of Figure 3 and
  • FIG. 5 shows a cross section through the brush head in another embodiment.
  • toothbrush 1 and 2 show a toothbrush 1 intended for manual use. It has a handle 2, a preferably flexible neck 3 and a brush head 4 with a bristle trim 5.
  • the bristle stock 5 consists of individually standing bristles arranged at a short distance from one another, as can be seen from FIGS. 3 and 4.
  • the ends 7 of the individual bristles 6 are anchored in the brush head 4.
  • the individual bristles at their ends 7 have thickenings 8 obtained by melting them, by means of which they are anchored in the plastic of the brush head 4 by extrusion coating.
  • the bristles 6 have a diameter between 0.095 and 0.225 mm and a free length "1" of 5 to 9.5 mm. The shorter the free length "1", the smaller the diameter.
  • the following assignments have proven to be advantageous in practical tests: diameter 0.095 to 0.175 mm with a free length "1" of 5 to 7 mm and diameter 0.125 to 0.225 mm with a free length of 7 to 9.5 mm.
  • the overall height of the toothbrush in the area of the brush head is between 6.5 and 11 mm, the thickness "d" of the brush head being between 1.5 and 3.0 mm.
  • the embedment depth "a" of the individual bristles is between 0.2 and 0.8 mm, preferably about 0.4 mm.
  • the distance between the individual bristles 6 is preferably chosen so that there are about 600 bristles on a square centimeter.
  • the brush head is curved in cross section, so that the ends of the individual bristles 6 lie on a correspondingly curved envelope.
  • This envelope surface can also be corrugated or stepped by different lengths of the individual bristles 6.
  • the individual bristles are perpendicular to the surface of the brush head 4.
