Abstract

The plastic bristle (5) proposed consists of a core (6) of parallel plastic filaments (7) connected to each other, plus a plastic sheath (8) surrounding the core (6). At the brushing end (5a) of each bristle (5), the filaments (7) protrude out of the sheath (8). This is achieved by dressing the bristles (5) at the brushing end (5a), the length of the sheath (8) being reduced at the same time by this mechanically operation.

Description

Borsten aus Kunststoff für ZahnbürstenPlastic bristles for toothbrushes
Die vorliegende Erfindung betrifft eine Borste aus Kunststoff für Zahnbürsten sowie eine mit solchen Borsten bestückte Zahnbürste.The present invention relates to a plastic bristle for toothbrushes and a toothbrush equipped with such bristles.
Dieser Erfindung liegt nun die Aufgabe zugrunde, eine Kunststoffborste zu schaffen, die im Vergleich zu einer herkömmlichen Borste, die in der Regel aus einem verhältnismässig groben Monofilament besteht, eine bessere und schonendere Reinigungswirkung entfaltet.The object of this invention is to create a plastic bristle which, compared to a conventional bristle, which generally consists of a relatively coarse monofilament, has a better and gentler cleaning action.
Diese Aufgabe wird erfindungsgemäss mit einer Borste gemäss Anspruch 1 gelöst.This object is achieved according to the invention with a bristle according to claim 1.
Eine mit solchen Borsten ausgestattete Zahnbürste bildet Gegenstand des Anspruches 6.A toothbrush equipped with such bristles forms the subject of claim 6.
Weil der Kern der einzelnen Borsten aus einer Vielzahl von dünnen Filamenten besteht, ergibt sich eine bessere Reinigungswirkung als bei einer aus einem Monofilament bestehenden Kunststoffbörste .Because the core of the individual bristles consists of a large number of thin filaments, there is a better cleaning effect than with a plastic bristle consisting of a monofilament.
Durch das Vorstehen der Filamente über den Mantel wird an den Borstenenden eine faserige Struktur erreicht, welche eine schonende Reinigung der Zahnoberfläche gewährleistet, weil die Filamentenden in die feinsten Rillen und Vertiefungen der Zahnoberfläche sowie in die Interdentalräume eindringen können. Eine Verletzung des Zahnfleisches wird vermieden. Unterscheiden sich die Filamente optisch vom Borstenmantel, z.B. in Folge unterschiedlicher Farbgebung, so wird nicht nur eine besondere ästhetische Wirkung erzielt, sondern auch eine gut sichtbare Anzeige für den Gebrauchszustand der Zahnbürste geschaffen. Das Mass der Abnützung der Borsten lässt sich nämlich so leicht feststellen.By protruding the filaments over the sheath, a fibrous structure is achieved at the bristle ends, which ensures gentle cleaning of the tooth surface, because the filament ends can penetrate into the finest grooves and depressions on the tooth surface and into the interdental spaces. Injury to the gums is avoided. If the filaments differ optically from the bristle sheath, for example as a result of different colors, not only a special aesthetic effect is achieved, but also a clearly visible indication of the state of use of the toothbrush. The degree of wear of the bristles is so easy to determine.
Die Dicke der Borsten ist so gewählt, dass sie bei genügender Steifigkeit und Stabilität ausreichend flexibel sind und die gewünschte Feinheit aufweisen.The thickness of the bristles is selected so that they are sufficiently flexible with sufficient rigidity and stability and have the desired fineness.
Vorteilhafterweise besteht der Kern der Borsten aus wenigstens 2 Filamenten und vorzugsweise aus 20-60 Filamenten, was einen besonders wirkungsvollen und schonenden Reinigungseffekt zur Folge hat.The core of the bristles advantageously consists of at least 2 filaments and preferably 20-60 filaments, which results in a particularly effective and gentle cleaning effect.
Anhand der Zeichnung wird im folgenden ein Ausführungsbeispiel einer mit erfindungsgemässen Borsten bestückten Zahnbürste näher erläutert. Es zeigt rein schematisch:An exemplary embodiment of a toothbrush equipped with bristles according to the invention is explained in more detail below with reference to the drawing. It shows purely schematically:
Fig. 1 in Seitenansicht eine Zahnbürste,1 is a side view of a toothbrush,
Fig. 2 in einem gegenüber der Fig. 1 grösseren Massstab einen Teil des Kopfes der Zahnbürste gemäss Fig.l,2 on a larger scale than in FIG. 1, part of the head of the toothbrush according to FIG. 1,
Fig. 3 in einer vergrösserten Darstellung und teilweise im Schnitt den oberen Teil einer Einzelborste,3 in an enlarged view and partly in section the upper part of a single bristle,
Fig. 4 einen Schnitt entlang der Linie A-A in Fig. 3, und Fig. 5 teilweise im Schnitt das freie Ende einer Einzelborste während des Zahnreinigungsvorganges.Fig. 4 is a section along the line AA in Fig. 3, and Fig. 5 partially in section, the free end of a single bristle during the tooth cleaning process.
Die in Fig. 1 gezeigte Zahnbürste 1 weist auf bekannte Weise einen Handgriff 2 und einen mit diesem einstückigen Borstenträger 3 auf. In diesen Borstenträger 3 sind Borstenbündel 4 eingesetzt. Wie aus der Fig. 2 ersichtlich ist besteht jedes Borstenbündel 4 aus einer Vielzahl von Borsten 5.The toothbrush 1 shown in FIG. 1 has a handle 2 in a known manner and a bristle carrier 3 integral therewith. Bristle bundles 4 are inserted into this bristle carrier 3. As can be seen from FIG. 2, each bristle bundle 4 consists of a large number of bristles 5.
Anhand der Fig. 3 und 4 wird nun der Aufbau einer einzelnen Borste erläutert.The structure of a single bristle will now be explained with reference to FIGS. 3 and 4.
Jede Borste weist einen Kern 6 auf, der durch eine Anzahl von vorzugsweise zueinander parallelen Filamenten 7 aus Kunststoff gebildet wird. Dieser Kern 6 ist von einem Mantel 8 umgeben, der durch eine Matrix 9 aus Kunststoff gebildet wird, in die die Filamente 7 eingebettet sind, und zwar vorzugsweise hohlraumfrei. Die Filamente 7 und die Matrix 9 können aus demselben Kunststoff, vorzugsweise aus einem Polyamid bestehen. Am freien Ende 5a der Borste 5 stehen die Filamente 7 über den Mantel 8 vor, wie das aus den Fig. 3 und 5 hervorgeht. Dieses Vorstehen der Filamentenden entsteht dadurch, dass die Borsten 5 an ihrem freien Ende 5a durch ein geeignetes Abrundverfahren bearbeitet werden, wodurch der Mantel 8 mechanisch abgetragen wird. Die Filamentenden werden dabei aber nicht weggescheuert.Each bristle has a core 6 which is formed by a number of preferably parallel filaments 7 made of plastic. This core 6 is surrounded by a jacket 8, which is formed by a matrix 9 made of plastic, in which the filaments 7 are embedded, and preferably free of voids. The filaments 7 and the matrix 9 can consist of the same plastic, preferably of a polyamide. At the free end 5a of the bristle 5, the filaments 7 protrude beyond the jacket 8, as can be seen from FIGS. 3 and 5. This protrusion of the filament ends arises from the fact that the bristles 5 are machined at their free end 5a by a suitable rounding process, as a result of which the sheath 8 is removed mechanically. The filament ends are not chafed away.
Der Kern 6 besteht aus wenigs :ens 2 Filamenten, vorzugsweise aber aus 20-60 Filamenten 7. Die Filamente 7 haben eine Dicke (Durchmesser d) von 0,01 - 0,08 mm. Die Dicke (Durchmesser D) der Borsten 5 beträgt 0,1 - 0,3 mm, vorzugsweise 0,15 - 0,25 mm. Der Mantel 8 und die Filamente 7 sollen sich optisch voneinander unterscheiden. Dies wird auf besonders einfache Weise dadurch erreicht, dass die Filamente 7 eine andere Farbe haben als der Mantel 8. Mit dieser Massnahme wird eine besondere ästhetische Wirkung erreicht und die Möglichkeit zu einer Anzeige des Gebrauchszustandes der Zahnbürste geschaffen. Wegen der unterschiedlichen Färbung von Mantel 8 und der vorstehenden Filamentenden 7a lässt sich leicht erkennen, wann das freie Borstenende 5a abgenutzt ist, d.h. die vorstehenden Filamentenden 7a weggescheuert sind.The core 6 consists of at least 2 filaments, but preferably 20-60 filaments 7. The filaments 7 have a thickness (diameter d) of 0.01-0.08 mm. The thickness (diameter D) of the bristles 5 is 0.1-0.3 mm, preferably 0.15-0.25 mm. The sheath 8 and the filaments 7 should differ optically from one another. This is achieved in a particularly simple manner in that the filaments 7 have a different color than the sheath 8. This measure achieves a special aesthetic effect and creates the possibility of displaying the state of use of the toothbrush. Because of the different coloring of the jacket 8 and the protruding filament ends 7a, it can be easily recognized when the free bristle end 5a is worn out, ie the protruding filament ends 7a have been chafed away.
Die Fig. 5 lässt ohne weiteres die Vorteile erkennen, die sich aus der besonderen Ausgestaltung der Borsten 5 ergeben. Die über den Mantel 8 vorstehenden Enden 7a der feinen Filamente bilden eine faserige Struktur, wodurch es möglich ist, in die feinsten Rillen und Vertiefungen in der Oberfläche 10a eines Zahnes 10 einzudringen und so eine schonende, jedoch sehr wirkungsvolle Reinigung zu erzielen. Zusätzlich wird das Zahnfleisch geschont. Die Borsten 5 haben einerseits eine ausreichende Steifigkeit und andererseits eine genügende Flexibilität, damit die gewünschte Reinigungswirkung erzielt werden kann.FIG. 5 shows the advantages that result from the special design of the bristles 5 without further ado. The ends 7a of the fine filaments projecting beyond the jacket 8 form a fibrous structure, which makes it possible to penetrate into the finest grooves and depressions in the surface 10a of a tooth 10 and thus achieve a gentle but very effective cleaning. In addition, the gums are spared. The bristles 5 have sufficient rigidity on the one hand and sufficient flexibility on the other hand so that the desired cleaning effect can be achieved.
Falls zwischen den den Borstenkern 6 bildenden Filamenten 7 einerseits und diesem Kern 6 und dem Mantel 8 andererseits keine Hohlräume vorhanden sind, wird das Eindringen von Fremdstoffen und -partikeln, wie z.B. Mikroorganismen, in die Borste 5 verhindert. If there are no voids between the filaments 7 forming the bristle core 6 on the one hand and this core 6 and the jacket 8 on the other hand, the penetration of foreign substances and particles, e.g. Microorganisms in the bristle 5 prevented.
