Definitions
- the invention relates to a bristle tuft for a toothbrush with a number of bristles of a first type and a number of bristles of a second type, wherein the bristles of the first type have a wear behavior that differs from the wear behavior of the bristles of the second kind.
- the invention further relates to a toothbrush with such a bristle tufts.
- bristle tufts known, which is formed of bristles with different diameters from each other.
- the cleaning effect of the toothbrush is to be improved, since thinner bristles can penetrate more easily into interdental spaces, while the thick bristles serve to clean the easily accessible tooth areas.
- each toothbrushes are known in which the bristles of the toothbrush consist of so-called indicator filaments.
- the indicator filaments have a colored area, and the use of the toothbrush causes the color in that colored area to change with continued use of the toothbrush. The change of color serves as an indicator of the wear of the toothbrush.
- Another bristle tuft is from the JP 2005 103184 A known.
- the invention has for its object to provide a bristle tufts for toothbrushes, in which the wear of the toothbrush to the user is particularly clearly displayed.
- the bristles of the first type preferably have a different mechanical wear behavior than the bristles of the second type. This may be due to different bristle geometries, cross-sectional shapes or surface structuring. Also, the cross-sectional area of the bristles of the second type may be smaller than the cross-sectional area of the bristles of the first type.
- the free ends of the bristles of the second type may have at least one predetermined breaking point, the continuous mechanical stress of the bristles of the second type causing the free ends of the bristles of the second kind to be split.
- the bristles of the second type can have a color-changeable wear indicator.
- Fig. 1a shows a first embodiment of a bristle tufts 1 in a perspective view.
- the bristle tufts 1 consists of a number of bristles, wherein a number of bristles of the first type 2 and a number of bristles of the second type 3 are present.
- the bristles of the first type 2 each have a color-changeable wear indicator 5 at the free end.
- the color-changeable wear indicator 5 is characterized essentially by the fact that the color of the wear indicator changes with continuous use of the toothbrush, so that upon reaching a predetermined color of the wear indicator, for example the color white, the user is signaled that the recommended service life of the wear indicator Toothbrush is reached, or the bristles are worn.
- the bristles of the second type 3 are arranged substantially in the inner region of the bristle tufts 1.
- the bristles of the second type 3 have a smaller cross-sectional area or diameter in relation to the bristles of the first type 2.
- the smaller diameter of the bristles 3 causes them to wear mechanically with increasing useful life of the toothbrush in a different way than the much thicker bristles of the first type 2.
- the mechanical wear causes, for example, that the bristles of the second type 3 towards the end of the recommended service life of Toothbrush bend.
- the user of the toothbrush hereby receives, in addition to the color indication of the wear indicator 5, a further indication of the end of the recommended service life of the toothbrush.
- the diameter of the bristles of the second type 4 in the non-spliced state can also correspond to the diameter of the bristles 2 of the first type.
- a cross section through such a bristle tufts with spliceable bristles 4 of the second kind is shown in FIG Fig. 3 shown.
- Fig. 4a a further embodiment of a spliceable bristle 4 in cross-section, wherein the bristle has a substantially cloverleaf-shaped cross-sectional area.
- the upper part of the free end of the spliceable bristle 4 consists essentially of three bristle segments 4a, 4b, 4c, which are of uniform design in the longitudinal direction.
- the three bristle segments are first firmly joined together in the longitudinal direction.

Description
Die Erfindung betrifft ein Borstenbüschel für eine Zahnbürste mit einer Anzahl von Borsten einer ersten Art und einer Anzahl von Borsten einer zweiten Art, wobei die Borsten erster Art ein Verschleißverhalten aufweisen das vom Verschleißverhalten der Borsten zweiter Art abweicht. Die Erfindung betrifft weiterhin auch eine Zahnbürste mit einem derartigen Borstenbüschel.The invention relates to a bristle tuft for a toothbrush with a number of bristles of a first type and a number of bristles of a second type, wherein the bristles of the first type have a wear behavior that differs from the wear behavior of the bristles of the second kind. The invention further relates to a toothbrush with such a bristle tufts.

Der Erfindung liegt die Aufgabe zugrunde, ein Borstenbüschel für Zahnbürsten bereitzustellen, bei welchem der Verschleiß der Zahnbürste dem Anwender besonders deutlich angezeigt wird.The invention has for its object to provide a bristle tufts for toothbrushes, in which the wear of the toothbrush to the user is particularly clearly displayed.
Die Lösung dieser Aufgabe gelingt mit einem Borstenbüschel gemäß Anspruch 1.The solution of this problem is achieved with a bristle tufts according to claim 1.
Durch die Verwendung verschiedener Abnutzungsindikatoren innerhalb eines Borstenbüschels wird der Verschleiß noch deutlicher und genauer sichtbar. Das Ende der empfohlenen Nutzungsdauer der Zahnbürste kann dadurch dem Verwender der Zahnbürste noch präziser angezeigt werden. Zusätzlich wird verhindert, dass ein unterschiedliches Putzverhalten bzw. eine unterschiedliche Putztechnik die Anzeige des Verschleißes und damit auch das tatsächliche Ende der empfohlenen Nutzungsdauer verfälschen.The use of different wear indicators within a bristle tuft makes the wear even more visible and more visible. The end of the recommended service life of the toothbrush can thereby be displayed more precisely to the user of the toothbrush. In addition, it is prevented that a different cleaning behavior or a different cleaning technique distort the display of wear and thus the actual end of the recommended service life.
Vorzugsweise besitzen die Borsten erster Art ein anderes Verhalten bezüglich mechanischen Verschleißes als die Borsten zweiter Art. Dies kann durch unterschiedliche Borstengeometrien, -querschnittsformen oder Oberflächenstrukturierungen bedingt sein. Auch kann die Querschnittsfläche der Borsten zweiter Art kleiner sein als die Querschnittsfläche der Borsten erster Art.The bristles of the first type preferably have a different mechanical wear behavior than the bristles of the second type. This may be due to different bristle geometries, cross-sectional shapes or surface structuring. Also, the cross-sectional area of the bristles of the second type may be smaller than the cross-sectional area of the bristles of the first type.
Es können die freien Enden der Borsten zweiter Art mindestens eine Sollbruchstelle aufweisen, wobei die fortlaufende mechanische Beanspruchung der Borsten zweiter Art das Aufspleißen der freien Enden der Borsten zweiter Art bewirkt. Zusätzlich können die Borsten zweiter Art einen farblich veränderbaren Verschleißindikator aufweisen.The free ends of the bristles of the second type may have at least one predetermined breaking point, the continuous mechanical stress of the bristles of the second type causing the free ends of the bristles of the second kind to be split. In addition, the bristles of the second type can have a color-changeable wear indicator.

Die Borsten zweiter Art 3 sind im Wesentlichen im inneren Bereich des Borstenbüschels 1 angeordnet. Die Borsten zweiter Art 3 weisen eine im Verhältnis zu den Borsten erster Art 2 geringere Querschnittsfläche bzw. Durchmesser auf. Der geringere Durchmesser der Borsten 3 führt dazu, dass sich diese bei zunehmender Nutzungsdauer der Zahnbürste mechanisch in anderer Weise abnutzen als die wesentlich dickeren Borsten erster Art 2. Die mechanische Abnutzung bewirkt beispielsweise, dass sich die Borsten zweiter Art 3 gegen Ende der empfohlenen Nutzungsdauer der Zahnbürste verbiegen. Der Benutzer der Zahnbürste erhält hiermit zusätzlich zur farblichen Anzeige des Verschleißindikators 5 einen weiteren Hinweis auf das Ende der empfohlenen Nutzungsdauer der Zahnbürste.The bristles of the
Durch die Verwendung unterschiedlicher Borsten in einem Borstenbüschel, welche jeweils auf unterschiedliche Art und Weise einem Verschleiß unterliegen, kann der Verschleiß der Borsten und damit die empfohlene Nutzungsdauer einer Zahnbürste dem Benutzer noch deutlicher und noch genauer angezeigt werden.

Fig. 1b illustriert das inFig. 1a gezeigten Borstenbüschel 1 im Querschnitt. Wie hier erkennbar ist, sind die dicken Borsten ersterArt 2 im Außenbereich des Büschels 1 angeordnet, während die dünnen Borsten zweiterArt 3 im Innenbereich des Borstenbüschels 1 angeordnet sind. Selbstverständlich kann die Anordnung der Borsten ersterArt 2 und der Borsten zweiterArt 3 in einem Borstenbüschel auch hiervon abweichend ausgestaltet sein. So können beispielsweise diedicken Borsten 2 so angeordnet sein, dass sie von einerAnzahl dünner Borsten 3 umgeben werden. Des Weiteren ist eine zufällige Anordnung der dickenBorsten 2 und der dünnenBorsten 3 innerhalb des Borstenbüschels 1 möglich. -
Fig. 2a zeigt ein weiteres Ausführungsbeispiel eines Borstenbüschels 1. Das Borstenbüschel 1 besteht aus einer Anzahl ersterBorsten 2, welche jeweils einen farblichen Verschleißindikator 5, wie bereits inFig. 1a gezeigt, aufweisen, und einer Anzahl zweiterBorsten 4, welche im Inneren des Borstenbüschels 1 angeordnet sind und somitvon den Borsten 2 erster Art umgeben werden. In diesem Ausführungsbeispiel weisen dieBorsten 4 zweiter Art ebenfalls einen geringeren Durchmesser als dieBorsten 2 erster Art auf. Zusätzlich sind dieBorsten 4 zweiter Art an deren freien Ende in Längsrichtung aufspleißbar ausgestaltet. - Bei diesem Ausführungsbeispiel eines Borstenbüschels 1 erhält der Benutzer, wie auch im Ausführungsbeispiel nach
Fig. 1a , anhand der an den Borsten ersterArt 2 vorgesehenen farblich veränderbaren Verschleißindikatoren einen ersten Hinweis auf das empfohlene Ende der Nutzungsdauer. Ein weiterer Hinweis auf das Ende der empfohlenen Benutzungsdauer wird dem Benutzer durch dieBorsten 4 zweiter Art gegeben. Die Borsten zweiterArt 4 sind so ausgestaltet, dass sich das freie Ende dieser Borsten gegen Ende der empfohlenen Nutzungsdauer aufspleißt. -
Fig. 2b zeigt einen Querschnitt durch das inFig. 2a gezeigte Borstenbüschel. Diedünnen aufspleißbaren Borsten 4 zweiter Art sind hier so angeordnet, dass sie von den dickenmit farblichen Verschleißindikatoren 5 versehenen Borsten umgeben sind. Eine andere Anordnung der Borsten ersterArt 2 und derBorsten 4 zweiter Art ist hier ebenfalls möglich. Des Weiteren sind dieBorsten 4 zweiter Art im Durchmesser dünner als dieBorsten 2 erster Art. Dadurch ist es möglich, neben der Anzeige des mechanischen Verschleißes derBorsten 4 zweiter Art durch Aufspleißen des freien Endes dieser Borsten zusätzlich noch die Anzeige des Verschleißes, beispielsweise durch Verbiegen, wie im Ausführungsbeispiel zuFig. 1a gezeigt, bereitzustellen.

Fig. 1b illustrates this inFig. 1a shown bristle tufts 1 in cross section. As can be seen here, the thick bristles of thefirst type 2 are arranged in the outer region of the tuft 1, while the thin bristles of thesecond type 3 are arranged in the inner region of the tuft 1. Of course, the arrangement of the bristles of thefirst type 2 and the bristles of thesecond type 3 in a tuft of bristles may also be deviating therefrom. For example, thethick bristles 2 may be arranged so that they are surrounded by a number ofthin bristles 3. Furthermore, a random arrangement of thethick bristles 2 and thethin bristles 3 within the bristle tufts 1 is possible. -
Fig. 2a shows a further embodiment of a bristle tufts 1. The bristle tufts 1 consists of a number offirst bristles 2, each having acolor wear indicator 5, as already inFig. 1a shown, and a number ofsecond bristles 4, which are arranged in the interior of the bristle tufts 1 and thus surrounded by thebristles 2 of the first kind. In this embodiment, thebristles 4 of the second type also have a smaller diameter than thebristles 2 of the first kind. In addition, thebristles 4 of the second type are spliceable at the free end in the longitudinal direction. - In this embodiment, a bristle tufts 1, the user, as in the embodiment according to
Fig. 1a , On the basis of the bristles of thefirst type 2 provided color-changeable wear indicators a first indication of the recommended end of the useful life. Another indication of the end of the recommended period of use is given to the user by thebristles 4 of the second type. The bristles of thesecond type 4 are designed such that the free end of these bristles splices towards the end of the recommended service life. -
Fig. 2b shows a cross section through the inFig. 2a bristle tufts shown. The thinspliceable bristles 4 of the second type are here arranged so that they are surrounded by the thick bristles provided withcolor wear indicators 5. Another arrangement of the bristles of thefirst type 2 and thebristles 4 of the second type is also possible here. Furthermore, thebristles 4 of the second type are thinner in diameter than thebristles 2 of the first type. This makes it possible, in addition to the indication of the mechanical wear of thebristles 4 second type by splicing the free end of these bristles in addition to the display of wear, for example, by bending, as in the embodiment toFig. 1a shown to provide.
