Abstract

A tooth brush for simultaneously cleaning both sides of at least one row of teeth has at least two bristle holders (3) and bristles (6) that during use extend toward each other, resp. from both sides, against a row of teeth (10), and that deviate from the bristle holder (3) away form the perpendicular in the direction of the gums (11) by an angle between 1 DEG and 10 DEG . During use, the bristles (6d, 6c, 6b, 6a) are softer resp. longer as they extend away from the cutting or grinding zones (10a) of the teeth and approach the gums (11). During use, the ground plan of the bristle holder (3) is not wider than two teeth (10), preferably at the maximum as wide as one and a half teeth, especially not wider than a (for example molar) tooth.

Description

M A S S A G E Z A H N B U E R S T E M A S S A G E Z A H N B U E R S T E

Die Erfindung betrifft eine Zahnbürste nach dem Oberbegriff des Anspruches 1, wie sie z.B. aus der internationalen PCT- Anmeldung PCT/EP86/00354 (Veröffentlichungsnr. Wθ/86/07527) bekanntgeworden ist. Eine solche Zahnbürste hat trotz der in der Druckschrift angegebenen Vorteile noch mit dem Problem zu kämpfen, dass die gegen das Zahnfleisch gerichteten Borsten, wenn die Borsten für die Reinigung der Zähne genügend hart sind, zu stark in das Zahnfleisch eindringen.The invention relates to a toothbrush according to the preamble of claim 1 as e.g. has become known from the international PCT application PCT / EP86 / 00354 (publication number Wθ / 86/07527). In spite of the advantages specified in the publication, such a toothbrush still has to struggle with the problem that the bristles directed against the gums, if the bristles are sufficiently hard to clean the teeth, penetrate too strongly into the gums.

Dieses Problem wird erfindungsgemäss durch das Merkmal des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfin¬ dung sind in den Merkmalen der Unteransprüche beschrieben.According to the invention, this problem is solved by the feature of claim 1. Advantageous developments of the invention are described in the features of the subclaims.

Dadurch, dass die Borsten zum Zahnfleisch hin weicher werden (was bei gleichem Borstenmaterial auch dadurch bewerkstelligt werden kann, dass sie zum Zahnfleisch hin länger werden), er¬ folgt eine sanfte Massage des Zahnfleisches, wobei eine Rei¬ nigung der vom Zahnfleisch abgewandten Zahnteile durch die kürzeren, bzw. härteren Borsten ausreichend erfolgt.Because the bristles become softer towards the gums (which can also be achieved with the same bristle material by lengthening towards the gums), the gums are gently massaged, whereby the tooth parts facing away from the gums are cleaned by the shorter or harder bristles are sufficient.

Die dünnsten Borsten von nur 0,12 mm werden insbesondere für die Massage von frischoperiertem Zahnfleisch oder für Klein- r kinder verwendet.The thinnest bristles of just 0.12 mm are used in particular for the massage of freshly operated gums or for small children.

Die gegebenenfalls im Steg der Zahnbürste für die Reinigung der Schneid- bzw. Mahlzone der Zähne vorgesehenen, parallel zu den Zähnen gerichteten Borsten sind vorzugsweise um 0,02 bis 0,03 mm dicker, bzw. um einen entsprechenden Faktor här¬ ter als die Borsten in den für die Massage des Zahnfleisches vorgesehenen Borstenbündeln.The bristles which are optionally provided in the web of the toothbrush for cleaning the cutting or grinding zone of the teeth and are oriented parallel to the teeth are preferably 0.02 to 0.03 mm thicker or a corresponding factor harder than the bristles in the bristle bundles intended for the massage of the gums.

ERSATZBLATT Besonders zweckmässig hat sich im Zusammenhang mit den erfin- dungsgemäss vorgeschlagenen Massnahmen die Beschränkung der Breite der Borstenhalter erwiesen, die bewirken, dass die Borsten beim Darübergleiten über die Zwischenräume zwischen zwei Zähnen in diese besser eindringen können und auch dort Speisereste und Zahnbelag entfernen.REPLACEMENT LEAF In connection with the measures proposed according to the invention, it has proven particularly expedient to limit the width of the bristle holders, which have the effect that the bristles can penetrate better through the spaces between two teeth and also remove food residues and dental plaque there.

Die Erfindung ist anhand der Zeichnung beispielhaft erläu¬ tert, wobei eine Doppelzahnbürste zur gleichzeitig beidseiti- gen Reinigung beider Zahnreihen in den Fig. 1 und 3 im Quer¬ schnitt gezeigt ist (in letzterer in Gebrauchsläge) , während Fig. 2 den Grundriss einer Zahnbürsre mit gegebenenfalls nur zwei Borstenhaltern zeigt.The invention is illustrated by way of example with reference to the drawing, a double toothbrush for simultaneously cleaning both rows of teeth on both sides being shown in cross section in FIGS. 1 and 3 (in the latter in the position of use), while FIG. 2 shows the outline of a toothbrush with possibly only two bristle holders.
