Description

Die Erfindung betrifft einen Bürstenkopf für eine Zahnbürste gemäss dem Oberbegriff des Anspruchs 1.The invention relates to a brush head for a Toothbrush according to the preamble of claim 1.

Aus der FR-A -683 311 ist eine Zahnbürste mit einem gattungsgemässen Bürstenkopf bekannt, bei dem jeweils eine Doppelreihe von in Längsrichtung des Bürstenkopfes schräggestellten, sich kreuzenden Borstenbüscheln mit jeweils einer Querreihe von rechtwinklig zum Borstenträger stehenden Borstenbüscheln abwechselt. Die letztgenannten Borstenbüschel sind unter sich gleich lang sowie kürzer und dicker als die schräg gestellten Borstenbüschel. Die letzte Querreihe im vorderen Bereich des Bürstenkopfes wird durch schräg gestellte Borstenbüschel gebildet. Beim Reinigen der Zähne wird die Zahnbürste in vertikaler Richtung hin und herbewegt, was dank der erwähnten besonderen Anordnung der Borstenbüschel zu einer verbesserten Reinigung sowohl der Zahnflächen wie auch der Zahnzwischenräume führt.From FR-A-683 311 is a toothbrush with a Generic brush head known, each with one Double row of in the longitudinal direction of the brush head inclined, crossing bristle tufts with one transverse row each at right angles to the bristle holder alternating standing bristle tufts. The latter Tufts of bristles are the same length among themselves and shorter and thicker than the slanted tufts of bristles. The last transverse row in the front area of the brush head is formed by inclined tufts of bristles. At the Cleaning the teeth will make the toothbrush vertical Direction back and forth, which thanks to the mentioned special arrangement of the tufts of bristles improved cleaning of both the tooth surfaces and the Interdental spaces leads.

In der US-A-5, 274,873 (Fig.2) ist eine Zahnbürste offenbart, deren Borstenbüschel mit ihren freistehenden Enden eine aus zwei Teilen bestehende Bürstfläche bilden. Der eine Bürstflächenteil ist eben und wird durch die Enden von im wesentlichen senkrecht zum Borstenträger stehenden Borstenbüscheln gleicher Länge gebildet. Der andere Bürstflächenteil ist in Längsrichtung des Bürstenkopfes geneigt und steigt zum vorderen Ende des Bürstenkopfes hin an. Dieser geneigte Bürstflächenteil wird durch die Enden von Borstenbüscheln gebildet, die etwa rechtwinklig vom nach oben abgekröpften Endteil des Borstenträgers abstehen. Mit dieser bekannten Zahnbürste soll während des Zahnreinigungsvorganges der Zugang zu den verschiedenen Zahnbereichen verbessert werden.In US-A-5, 274,873 (Fig.2) is a toothbrush discloses whose tufts of bristles with their free-standing Form ends of a brush surface consisting of two parts. One part of the brush surface is flat and is covered by the Ends of substantially perpendicular to the bristle carrier standing tufts of bristles of the same length are formed. The other brush surface part is in the longitudinal direction of the Brush head tilted and rises to the front end of the Brush head. This inclined part of the brush surface is formed by the ends of tufts of bristles approximately at a right angle from the end portion of the Protrude bristle carrier. With this well-known toothbrush should access to the teeth during the tooth cleaning process different tooth areas can be improved.

Der vorliegenden Erfindung liegt nun die Aufgabe zu Grunde, einen Bürstenkopf zu schaffen, der eine im Vergleich zum vorbekannten gattungsgemässen Bürstenkopf weiter verbesserte Reinigung der Zähne und der Interdentalräume ermöglicht.The object of the present invention is now Reason to create a brush head that one in Comparison to the previously known generic brush head further improved cleaning of the teeth and the Interdental spaces enabled.

Gelöst wird diese Aufgabe durch einen Bürstenkopf mit den Merkmalen des neuen Anspruches 1.This task is solved by a brush head with the Features of the new claim 1.

Dadurch, dass sowohl Querreihen mit zum Borstenträger im wesentlichen senkrecht stehenden Borstenbüscheln als auch mindestens ein Paar von Querreihen, die in Längsrichtung der Zahnbürste schräggestellte, sich gegenseitig kreuzende Borstenbündel umfassen, vorhanden sind, wird sowohl eine einwandfreie Reinigung der Zahnoberflächen, als auch ein besseres Eindringen in die Zahnzwischenräume erreicht. Die durch diese besondere Anordnung der Borstenbüschel verursachte gute Reinigungswirkung wird deswegen noch weiter erhöht, weil im vorderen Bereich des Bürstenkopfes mehrere nebeneinander liegende Querreihen mit im Wesentlichen senkrecht vom Borstenträger abstehenden, unterschiedlich langen Borstenbüscheln vorgesehen sind, deren freistehenden Enden einen zum vorderen Ende des Bürstenkopfes hin ansteigende Bürstfläche bilden, was zu einer besseren Anpassung der Bürstfläche an Gebiss und Zahnform führt. The fact that both transverse rows with the bristle carrier in essentially vertical tufts of bristles as well at least one pair of transverse rows in the longitudinal direction the toothbrush is slanted, crossing each other Bristle bundles are present, both will flawless cleaning of the tooth surfaces, as well as a better penetration into the interdental spaces. The due to this special arrangement of the bristle tufts The good cleaning effect caused is therefore still further increased because in the front area of the brush head several adjacent rows with in Protruding substantially perpendicularly from the bristle carrier, bristle tufts of different lengths are provided, the free ends of which one towards the front end of the Brush head rising brush surface form what to a better adaptation of the brush surface to teeth and Tooth shape leads.

Bevorzugte Weiterausgestaltungen des erfindungsgemässen Bürstenkopfes bilden den Gegenstand der abhängigen Ansprüche.Preferred further developments of the invention Brush head form the object of the dependent claims.

Fig. 1 bis 3 zeigen einen vorderen Teil einer Handzahnbürste 1, der mit einem Bürstenkopf 2 ausgestattet ist. Der Bürstenkopf 2 weist einen Borstenträger 3 auf, in welchem jeweils aus einer Mehrzahl von Borsten gebildete Borstenbüschel 4, 5, 6 verankert sind. Mit 4 sind diejenigen Borstenbüschel bezeichnet, die im wesentlichen senkrecht zum Borstenträger 3 gerichtet sind. Es sind ausserdem zum Borstenträger schräggestellte Borstenbüschel 5, 6 vorhanden, wobei die Borstenbüschel 5 in Längsrichtung der Zahnbürste nach hinten, die Borstenbüschel 6 hingegen nach vorne geneigt sind. Der Neigungswinkel dieser Borstenbüschel 5, 6 gegenüber der Senkrechten kann bis zu 45° betragen (in der Zeichnung ist ein kleinerer Neigungswinkel dargestellt). Die freistehenden Enden aller Borsten bilden eine gegebenenfalls ebene Bürstfläche 10 (Fig. 3). Die Längsachse der Zahnbürste 1 ist in Fig. 2 mit 7 bezeichnet.1 to 3 show a front part of a Manual toothbrush 1 equipped with a brush head 2 is. The brush head 2 has a bristle holder 3, in each of which a plurality of bristles formed bristle tufts 4, 5, 6 are anchored. With 4 those tufts of bristles are designated that are essentially directed perpendicular to the bristle carrier 3 are. They are also inclined to the bristle holder Bristle tufts 5, 6 are present, the bristle tufts 5 in the longitudinal direction of the toothbrush behind, the bristle tufts 6, however, inclined forward are. The angle of inclination of these tufts of bristles 5, 6 with respect to the vertical can be up to 45 ° (in the drawing is a smaller angle of inclination ) Shown. Form the free-standing ends of all bristles an optionally flat brush surface 10 (FIG. 3). The longitudinal axis of the toothbrush 1 is designated 7 in FIG. 2.

Wie aus Fig. 2 ersichtlich sind die Borstenbüschel 4, 5, 6 nebeneinander in mehreren zur Längsrichtung der Zahnbürste rechtwinklig gerichteten Querreihen 14, 15, 16 angeordnet; gegebenenfalls sind drei Gruppen von je drei Querreihen 14 vorhanden, die durch die senkrecht zum Borstenträger 3 gerichteten Borstenbüschel 4 gebildet sind. Zwischen diesen Gruppen sind jeweils zwei Querreihen 15, 16 nebeneinander angeordnet, von denen die Querreihen 15 die nach hinten geneigten Borstenbüschel 5 enthalten, während in den Querreihen 16 die nach vorne geneigten Borstenbüschel 6 angeordnet sind, derart, dass sich die Borstenbüschel 5, 6 der benachbarten Querreihen 15, 16 gegenseitig kreuzen und paarweise ein X-förmige Anordnung bilden (vgl. insbesondere Fig. 1). Alle schräggestellten Borstenbüschel 5 bzw. 6 einer Querreihe 15 bzw. 16 weisen den gleichen Neigungswinkel auf. Der Neigungswinkel der Borstenbüschel 5 der einen Querreihe 15 eines Querreihenpaares 15, 16 gegenüber der Senkrechten gleicht dem negativen Neigungswinkel der Borstenbüschel 6 der anderen Querreihe 16, so dass ein in Längsrichtung symmetrisches X-Gebilde entsteht. Die beiden Querreihenpaare 15, 16 mit den sich kreuzenden, geneigten Borstenbüscheln 5, 6 sind in einem etwa einer durchschnittlichen Zahnbreite entsprechenden Abstand angeordnet.As can be seen from Fig. 2, the tufts of bristles 4, 5, 6 side by side in several to the longitudinal direction the toothbrush perpendicular rows 14, 15, 16 arranged; possibly three Groups of three transverse rows 14 each, the through the perpendicular to the bristle carrier 3 Bristle tufts 4 are formed. Between these groups are two transverse rows 15, 16 side by side arranged, of which the transverse rows 15 to the rear inclined tufts of bristles 5 while in the transverse rows 16 the bristle tufts inclined forward 6 are arranged such that the bristle tufts 5, 6 of the adjacent transverse rows 15, 16 cross each other and in pairs an X-shaped arrangement form (see in particular Fig. 1). All slanted Bristle tufts 5 or 6 of a transverse row 15 and 16 have the same angle of inclination. The Tilt angle of the bristle tufts 5 of a transverse row 15 of a pair of transverse rows 15, 16 compared to the Vertical equals the negative angle of inclination Bristle tufts 6 of the other transverse row 16, so that a longitudinally symmetrical X-structure is created. The two transverse rows 15, 16 with the crossing, inclined bristle tufts 5, 6 are in one about an average tooth width Distance arranged.

Fig. 4 bis 6 zeigen eine weitere Variante einer mit einem Bürstenkopf 2a ausgestatteten Handzahnbürste 1a. Der Borstenträger, die aufrechtstehenden und geneigten Borstenbüschel sowie die entsprechenden Querreihen sind weiterhin mit den gleichen Bezugsziffern bezeichnet wie in Fig. 1 bis 3. Bei dieser Ausführungsform ist allerdings nur eine Gruppe von drei aus senkrecht zum Borstenträger 3 stehenden Borstenbüscheln 4 gebildeten Querreihen 14 vorhanden, die - in Längsrichtung der Zahnbürste gesehen - zwischen je zwei Paaren von Querreihen 15, 16 angeordnet ist, die mit schrägstehenden, sich paarweise kreuzenden Borstenbüscheln 5, 6 versehen sind. Auch bei dieser Variante bilden die freistehenden Borstenenden eine ebene Bürstfläche 10 (Fig. 6).4 to 6 show a further variant of a manual toothbrush equipped with a brush head 2a 1a. The bristle carrier, the upright and inclined tufts of bristles and the corresponding Cross rows are still with the same reference numbers designated as in Figs. 1 to 3. In this embodiment is only one group out of three Bristle tufts standing perpendicular to the bristle carrier 3 4 transverse rows 14 formed, the - in Seen longitudinal direction of the toothbrush - between each two pairs of transverse rows 15, 16 is arranged, the with sloping tufts of bristles crossing in pairs 5, 6 are provided. This variant too the free-standing bristle ends form a flat surface Brush surface 10 (Fig. 6).

Eine in Fig. 7 bis 9 dargestellte dritte Ausführungsform einer Handzahnbürste 1b mit einem Bürstenkopf 2b entspricht im wesentlichen der ersten Variante nach Fig. 1 bis 3; die Querreihen 14 weisen die gleiche Anzahl von Borstenbüscheln, aber die äussersten seitlichen Aussenbüschel 18, 19 jeder Querreihe 14 sind in Querrichtung der Zahnbürste nach aussen geneigt (Fig. 8 und 9). Auch den mit den in Längsrichtung geneigten Borstenbüscheln 5, 6 versehenen, mit der mittleren Gruppe von Querreihen 14 benachbarten Querreihen 15, 16 ist seitlich je ein Aussenbüschel 20, 21 bzw. 22, 23 zugeordnet, das jeweils sowohl in Längsrichtung, als auch in Querrichtung der Zahnbürste 1b nach aussen schräggestellt ist (vgl. Fig. 8). Die Aussenbüschel 18, 20, 22 bzw. 19, 21, 23 bilden auf diese Weise je eine seitliche Längsreihe 26, 27 von in Querrichtung nach aussen schräg abstehenden Borstenbüscheln. Die durch alle Borstenbüschelenden gebildete Bürstfläche 10 ist wiederum eben ausgestaltet (Fig. 9).A third embodiment shown in FIGS. 7 to 9 a manual toothbrush 1b with a brush head 2b essentially corresponds to the first variant 1 to 3; the transverse rows 14 have the same Number of tufts of bristles, but the outermost ones Outer tufts 18, 19 of each transverse row 14 are in Cross direction of the toothbrush inclined outwards (Fig. 8 and 9). Even those with the inclined in the longitudinal direction Bristle tufts 5, 6 provided, with the middle Group of transverse rows 14 adjacent transverse rows 15, 16 is an outer tuft 20, 21 or 22 on each side, 23 assigned, each in the longitudinal direction, as also in the transverse direction of the toothbrush 1b to the outside is inclined (see FIG. 8). The outer tufts 18 20, 22 and 19, 21, 23 each form one in this way lateral longitudinal row 26, 27 from in the transverse direction bristle tufts protruding from the outside. The brush surface formed by all tufts of bristles 10 is in turn flat (Fig. 9).

In Fig. 10 bis 12 ist eine vierte Variante einer Handzahnbürste 1c mit einem Bürstenkopf 2c dargestellt, der eine Gruppe von vier und zwei Gruppen von zwei Querreihen 14 mit senkrecht zum Borstenträger 3 stehenden Borstenbüscheln 4 aufweist, zwischen denen jewils zwei Querreihen 15, 16 mit den zum Borstenträger 3 in Längsrichtung geneigten, sich paarweise kreuzenden Borstenbüscheln 5, 6 angeordnet sind. Bei dieser Variante überragen die schräggestellten Borstenbüschel 5, 6 in der Höhe die meisten der aufrechtstehenden Borstenbüschel 4; aber auch die vordere Gruppe von senkrecht zum Borstenträger 3 stehenden Borstenbüschel 4 weist unterschiedlich lange Borstenbüschel 4 auf, so dass im vorderen Bereich des Bürstenkopfes 2c ein in Längsrichtung geneigter, dem vorderen Ende des Bürstenkopfes 2c hinzu sich erhebender Bürstflächenteil 29 gebildet wird (Fig. 10).10 to 12 is a fourth variant of a Manual toothbrush 1c shown with a brush head 2c, which is a group of four and two groups of two transverse rows 14 perpendicular to the bristle carrier 3 has standing bristle tufts 4, between which each two transverse rows 15, 16 with the bristle carrier 3 inclined in the longitudinal direction, in pairs crossing bristle tufts 5, 6 are arranged. at this variant is dominated by the inclined tufts of bristles 5, 6 in height most of the upright Tufts of bristles 4; but also the front one Group of standing perpendicular to the bristle carrier 3 Bristle tufts 4 have bristle tufts of different lengths 4 so that in the front area of the brush head 2c an inclined in the longitudinal direction, the front End of the brush head 2c rising Brush surface part 29 is formed (Fig. 10).

Selbstverständlich könnte ein derartig geneigter Bürstflächenteil 29 auch den anderen vorstehend beschriebenen Ausführungsformen zugeordnet sein. Diese Ausführungsformen könnten aber auch mit in der Höhe die aufrechtstehenden Borstenbüschel 4 überragenden geneigten Borstenbüscheln 5, 6 ausgestattet sein.Of course, one might be more inclined Brush surface part 29 also the other above described embodiments may be assigned. These embodiments could also be used in the Height of the upstanding tufts of bristles 4 inclined bristle tufts 5, 6 equipped his.

Bei allen vorstehend beschriebenen Ausführungsformen von Zahnbürsten 1, 1a, 1b und 1c sorgen beim Zahnreinigungsvorgang die senkrecht zum Borstenträger 3 stehenden Borstenbüschel 4 vor allem für die Reinigung von Zahnflächen. Mit den in Längsrichtung der Zahnbürste schräggestellten Borstenbüscheln 5, 6 werden die Zahnzwischenräume besser erreicht und der Zahnfleischsaum (d.h. der Bereich des Überganges Zähne/Zahnfleisch) wirkungsvoller behandelt. Beim Zahnreinigungsvorgang, d.h. bei der Hin- und Herbewegung der Zahnbürste in Längsrichtung kommen dabei bei Bewegung in einer Richtung die nach hinten geneigten Borstenbüschel 5 der Querreihen 15, bei der Bewegung in der anderen Richtung die anderen, nach vorne geneigten Borstenbüschel 6 der Querreihen 16 zur Wirkung, nämlich zum besseren Eindringen in die schwer erreichbaren Interdentalräume. Während diese in einer Richtung geneigten und in der einen Bewegungsrichtung wirksamen Borstenbüschel 5 bzw. 6 an den Zähnen anstossen und in die Interdentalräume gedrängt werden, werden die anders geneigten Borstenbüschel 6 bzw. 5 über die Zahnoberflächen geschleppt und üben eine Wischwirkung aus. In der anderen Bewegungsrichtung werden die Rollen der Borstenbüschel 5,6 getauscht. Durch diese in beiden Bewegungsrichtungen stattfindende Stoss-/Schleppwirkung der in Längsrichtung der Zahnbürste symmetrisch angeordneten, schrägstehenden Borstenbüschelreihen 15, 16 mit sich paarweise kreuzenden Borstenbüscheln 5, 6 wird eine doppelte Reinigungswirkung erreicht und eine hervorragende Massage des Zahnfleisches bewirkt. Die eine bessere Durchblutung des Gewebes bewirkende Massage hat eine positive Auswirkung auf die Gesunderhaltung des Zahnfleischsaumes.In all the embodiments described above of toothbrushes 1, 1a, 1b and 1c during the tooth cleaning process the perpendicular to the bristle holder 3 standing bristle tufts 4 especially for cleaning tooth surfaces. With the lengthways the toothbrush tilts 5, 6 the interdental spaces are better reached and the gum line (i.e. the area of the transition Teeth / gums) treated more effectively. During the tooth cleaning process, i.e. in the float the toothbrush come in the longitudinal direction when moving in one direction to the rear inclined bristle tufts 5 of the transverse rows 15, in the Moving in the other direction the others, after Bristle tufts 6 inclined at the front of the transverse rows 16 to the effect, namely for better penetration into the difficult to reach interdental spaces. While this inclined in one direction and in one direction of movement effective tufts of bristles 5 or 6 bumping their teeth and pushed into the interdental spaces the differently inclined tufts of bristles 6 or 5 dragged over the tooth surfaces and have a wiping effect. In the other direction become the roles of the bristle tufts 5.6 exchanged. Through this in both directions of movement the impact / towing effect of the in Longitudinal direction of the toothbrush arranged symmetrically, sloping rows of bristles 15, 16 with bristle tufts 5, 6 crossing in pairs a double cleaning effect is achieved and one excellent massage of the gums. The better blood circulation in the tissue Massage has a positive effect on maintaining health of the gumline.

Durch das Hervorstehen der der in Längsrichtung geneigten, sich kreuzenden Borstenbüscheln 5, 6 gegenüber den aufrechtstehenden Borstenbüscheln 4 (vgl. als Beispiel die vierte Variante gemäss Fig. 10 bis 12) wird der Effekt des Eindringens in die Zahnzwischenräume zusätzlich verstärkt.By protruding in the longitudinal direction inclined, intersecting tufts of bristles 5, 6 compared to the upright tufts of bristles 4 (cf. as an example the fourth variant according to FIGS. 10 to 12) the effect of penetration into the interdental spaces additionally reinforced.

Die Neigung der Bürstfläche im vorderen Bereich 29 (Fig. 10) bewirkt eine bessere Anpassung an die Gebiss- und Zahnform.The inclination of the brush surface in the front area 29 (Fig. 10) causes better adjustment to the bit and tooth shape.

Durch die Anordnung von Aussen-Längsreihen 26, 27 mit in Querrichtung nach aussen abstehenden Aussenbüscheln 18, 20, 22 bzw. 19, 21, 23 gemäss Fig. 7 bis 9 wird der Zahnfleischsaum (d.h. der Bereich des Überganges Zähne/Zahnfleisch) besser erreicht und der Massageeffekt des erfindungsgemässen Bürstenkopfes 2b zusätzlich verstärkt.Due to the arrangement of longitudinal rows outside 26, 27 with outwardly projecting in the transverse direction Outer tufts 18, 20, 22 or 19, 21, 23 according to 7 to 9 becomes the gum line (i.e. the area of the tooth / gum transition) better achieved and the massage effect of the brush head according to the invention 2b additionally reinforced.

Es wären selbstverständlich auch verschiedene andere Anordnungskombinationen mit einer anderen Borstenbüschelanzahl pro Querreihe 14, 15, 16 als dargestellt, mit einer anderen Anzahl von Querreihen 14 mit senkrecht zum Borstenträger 3 stehenden Borstenbüscheln 4 und mit einer anderen Anzahl von Querreihenpaaren 15, 16 mit den geneigten Borstenbüscheln 5, 6 möglich, als vorstehend beschrieben und dargestellt.Of course it would be different other combinations of arrangements with another Number of bristles per transverse row 14, 15, 16 as with a different number of transverse rows 14 with bristle tufts standing perpendicular to the bristle carrier 3 4 and with a different number of transverse rows 15, 16 with the inclined tufts of bristles 5, 6 possible, as described and shown above.
