Description

Bürste zur Zahnfleischmassage und Zahnreinigung und Verfahren zur Herstellung der Borsten einer solchenGum massage and tooth cleaning brush and bristle manufacturing method
Bürstebrush
Die Erfindung betrifft eine Bürste zur Zahnfleischmassage und Zahnreinigung, bestehend aus einem Borstenträger mit Griff und am Borstenträger einzeln oder in Bündeln be- festigten Borsten aus Kunststoff.The invention relates to a brush for gum massage and tooth cleaning, consisting of a bristle holder with a handle and bristles made of plastic which are attached to the bristle holder individually or in bundles.
Zur Mundhygiene gehört heute nicht nur die Zahnreinigung, sondern gleichermaßen auch die Zahnfleischmassage zur Vorbeugung von Gingivitis, Paradontose etc.. Zahnbürsten üblicher Art, ob manuell oder elektrisch angetrieben, erfüllen zwar die Aufgabe der Zahnreinigung hinreichend, nicht jedoch die der Zahnfleischmassage, insbesondere wenn beide Wirkungen auf einer einzigen Bewegungsbahn erzielt werden sollen. So sind für die Zahnreinigung, insbesondere auch der Interdentalräume, die Borstenenden besonders wirksam, für die Zahnfleischmassage aber häufig zu aggressiv, insbesondere wenn sie nicht einwandfrei verrundet oder durch Benutzung bereits abgeflacht sind. Für die Zahnfleischmassage hingegen sollten der Andruck und die Bewegungsbahn so gewählt werden, daß sich die Borsten umlegen und mit ihrer Mantelfläche eine Art Streichmassage bewirken. In dieser Lage sind sie aber wiederum für die Zahnreinigung weit weniger wirksam und für die Reinigung der Interdentalräume sogar untauglich.Oral hygiene today includes not only tooth cleaning, but also gum massage to prevent gingivitis, periodontal disease, etc. Toothbrushes of a conventional type, whether manually or electrically powered, do the job of cleaning teeth adequately, but not that of gum massage, especially if both Effects on a single trajectory should be achieved. For example, the bristle ends are particularly effective for cleaning teeth, especially in the interdental spaces, but are often too aggressive for gum massage, especially if they are not perfectly rounded or are already flattened by use. For the gum massage, however, the pressure and the path of movement should be selected so that the bristles fold over and cause a kind of stroking massage with their outer surface. But they are in this position again much less effective for cleaning teeth and even unsuitable for cleaning interdental spaces.
Eine effektive Zahnfleischmassage ist deshalb nur mit Spezialgeräten möglich, deren Arbeitsfläche in der Regel aus gummielastischen Materialien besteht und noppenartig profiliert ist (GB 398 919, US 1 892 068) . Diese Geräte sind nun wieder für die Zahnreinigung völlig ungeeignet. Es sind deshalb für eine vollständige Mundhygiene jeden- falls zwei Arbeitsgänge durchzuführen, gegebenenfalls sogar zwei verschiedene Geräte zu verwenden. Dies ist umständlich mit der Folge, daß sich solche Zahnfleisch¬ massagegeräte nicht einführen konnten.An effective gum massage is therefore only possible with special equipment, the work surface of which is usually made of rubber-elastic materials and has a nub-like profile (GB 398 919, US 1 892 068). These devices are now completely unsuitable for cleaning teeth. For complete oral hygiene, two work steps must therefore be carried out in any case, and two different devices may even have to be used. This is cumbersome with the consequence that such gum massagers could not be introduced.
Aus der Praxis sind ferner Zahnbürsten bekannt, deren Borstenbesatz den unterschiedlichen Zielrichtungen beim Putzen der Zähne und Massieren des Zahnfleischs angepaßt ist . Eine solche Zahnbürste weist einen vergleichsweise harten mittleren Besatz und im Außenbereich flexiblere Massageborsten auf. Hierbei handelt es sich zwangsläufig um einen Kompromiß, wobei die Zuweisung der unterschied¬ lichen Borstenbereiche zu den ihnen zugeordneten Behand¬ lungsbereichen -Zahn oder Zahnfleisch- durch den Benutzer nicht ohne weiteres möglich ist . Zudem wird dieser Kom- promiß jeweils durch Minderung der einen Wirkung auf Kosten der anderen geschlossen.Toothbrushes are also known in practice, the bristles of which are adapted to the different directions when brushing the teeth and massaging the gums. Such a toothbrush has a comparatively hard medium fill and more flexible massage bristles on the outside. This is inevitably a compromise, and it is not readily possible for the user to assign the different bristle areas to the treatment areas assigned to them - tooth or gums. In addition, this compromise is made by reducing one effect at the expense of the other.
Der Erfindung liegt die Aufgabe zugrunde, eine Bürste zur Zahnfleischmassage vorzuschlagen, die gleichermaßen effektiv die Zahnreinigung besorgt.The invention has for its object to propose a brush for gum massage, which is equally effective in cleaning teeth.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Borsten unter Bildung ausgeprägter, warzenartiger Wellenscheitel mit kurzer Wellenlänge quer zur ihrer Achse gewellt sind. Die erfindungsgemäß ausgebildete Borste weist, wie jede herkömmliche Borste ein verrundetes Arbeitsende auf, das gleichermaßen für die Zahnreinigung und für die Zahn¬ fleischmassage -dabei als eine Art Massagefinger- wirkt. Hinzukommt, daß beim nicht zu vermeidenden Umlegen der Borste die warzenartigen Wellenscheitel in ähnlicher Weise wirken wie die Borstenenden, und zwar sowohl bei der Zahnreinigung, als auch bei der Massage des Zahn¬ fleischs. Bei entsprechendem Andruck des Borstenbesatzes, bei dem sich die Borsten umlegen, sind also an jeder einzelnen im Eingriff befindlichen Borste zugleich mehre¬ re Wellenscheitel reinigend und/oder massierend wirksam. Es lassen sich also in einem Arbeitsgang mit einem einzi¬ gen Gerät die für eine einwandfreie Mundhygiene notwendi- gen Maßnahmen durchführen.This object is achieved in that the bristles are corrugated transversely to their axis to form pronounced wart-like crests with a short wavelength. The bristle designed according to the invention, like any conventional bristle, has a rounded working end, which acts equally for tooth cleaning and for the gum massage, thereby acting as a kind of massage finger. In addition, if the bristle cannot be avoided, the wart-like crests act in a similar way to the bristle ends, both when cleaning the teeth and when massaging the gums. With a corresponding pressure on the bristle stock, in which the bristles fold over, several shaft vertices are simultaneously cleaning and / or massaging at each individual bristle in engagement. It is therefore possible to carry out the measures necessary for perfect oral hygiene in one operation with a single device.
Aufgrund der Wellung der Borsten werden labyrinthartige Kanäle zwischen den einzelnen Borsten gebildet, in denen Zahnpflegemittel hervorragend gespeichert werden. Dies gilt insbesondere für die heute häufig verwendeten Gele, die in die Zwischenräume beim Auftragen eingedrückt werden können. Bei Zahnbürsten mit herkömmlichem Borsten¬ besatz tropfen solche Gele aufgrund ihrer geringen Visko¬ sität häufig ab und führen zu entsprechenden Verlusten. Andererseits kann eine solche Bürste leicht ausgespült werden und die Borsten und Borstenzwischenräume trocknen auch schnell ab, so daß sich Schmutz und Bakterien nicht einnisten können.Because of the corrugation of the bristles, labyrinth-like channels are formed between the individual bristles in which dental care products are stored excellently. This applies in particular to the gels that are frequently used today, which can be pressed into the gaps during application. In toothbrushes with conventional bristle trimmings, such gels often drip due to their low viscosity and lead to corresponding losses. On the other hand, such a brush can be easily rinsed out and the bristles and bristle spaces also dry quickly, so that dirt and bacteria cannot nest.
In bevorzugter Ausführung sind die Borsten in zwei oder mehr Ebenen gewellt, wodurch sichergestellt ist, daß unabhängig davon, wie sich die Borste beim Putzen umlegt, stets warzenartige Wellenscheitel in Wirkung treten.In a preferred embodiment, the bristles are corrugated in two or more planes, which ensures that, regardless of how the bristle turns when cleaning, wart-like crest of the shaft always comes into effect.
Während bei einem üblichen Kreisquerschnitt einer Borste die Wellenscheitel mehr oder weniger abgerundet sind, können bei einem von der Kreisform abweichenden Quer¬ schnitt einerseits bevorzugte Biegeebenen erzeugt werden, andererseits die Wellenscheitel stärker ausgeprägt wer¬ den. So können die Borsten beispielsweise einen ovalen Querschnitt, vorzugsweise aber einen polygonalen Quer¬ schnitt mit abgerundeten Längskanten aufweisen. Als polygonaler Querschnitt bietet sich insbesondere ein kreuzförmiger Querschnitt an.While with a usual circular cross-section of a bristle, the wave apexes are more or less rounded, In the case of a cross section deviating from the circular shape, preferred bending planes can be generated on the one hand, and on the other hand the wave crests are more pronounced. For example, the bristles can have an oval cross section, but preferably a polygonal cross section with rounded longitudinal edges. A cross-shaped cross section is particularly suitable as a polygonal cross section.
Die Wirkung der erfindungsgemäß ausgebildeten Borsten läßt sich ferner durch die Geometrie der einzelnen Welle beeinflussen. Beispielsweise kann die Wellenlänge das 1- bis 10-fache des Borstendurchmessers betragen, liegt aber vorteilhafterweise zwischen dem 1- und 5-fachen. In bevorzugter Ausführungsform ist die Wellenlänge kleiner als das 2-fache des Borstendurchmessers.The effect of the bristles designed according to the invention can also be influenced by the geometry of the individual shaft. For example, the wavelength can be 1 to 10 times the bristle diameter, but is advantageously between 1 and 5 times. In a preferred embodiment, the wavelength is less than twice the bristle diameter.
Ferner sollte die Wellenhöhe, d.h. der Abstand gegenüber¬ liegender Wellenscheitel, möglichst klein sein. Vorzugs- weise beträgt er das 1,2- bis 2-fache des Borstendurch¬ messers.Furthermore, the wave height, i.e. the distance between the opposite wave crests must be as small as possible. It is preferably 1.2 to 2 times the bristle diameter.
Schließlich ist auch die Form des Wellenscheitels von Bedeutung, wobei winklig ausgeprägte Wellenscheitel gegenüber abgerundeten bevorzugt sind.Finally, the shape of the wave apex is also important, with angular wave apexes being preferred over rounded ones.
Es ist zwar bei Drahtbürsten und -pinseln bekannt, die verwendeten Drahtstifte zu wellen, doch stehen hierbei Stabilitätsgründe und die Abrasivwirkung im Vordergrund (US 1 178 179, DE-U-79 06 716) . Ferner sind Haarnadel- Borsten bekannt (US 2 511 004) , die aus Kunststoff be¬ stehen, jedoch in ihrer Form der Naturborste möglichst nahe kommen sollen. Diese Borsten sind langwellig profi¬ liert und an ihren Enden zugespitzt . Sie sind in erster Linie für Pinsel und Malerbürsten bestimmt. Die Herstel¬ lung dieser Borsten erfolgt dadurch, daß ausgehend von einem Endlosmonofil dieses in gleichmäßigen Abständen durch Zugkräfte eingeschnürt wird. Anschließend werden die Borsten zugeschnitten, und zwar jeweils im Bereich der Einschnürung, so daß eine einzelne Borste mit zwei spitz zulaufenden Enden gebildet ist . Diese Einzelborste wird anschließend durch rechtwinklig zueinanderstehende Formrollen-Paare, die auf Abstand angeordnet sind, hin¬ durchgeführt . Um ein axiales Verdrehen der Borste bei Einwirken der Umformkräfte zu vermeiden, soll das Umfor- men unter gleichzeitiger Anwendung von Wärme erfolgen. Dies ist bei Borsten absolut unzuträglich, denn bei der Bildung der Borsten aus Endlosmonofilen werden die Mono- file verstreckt, gegebenenfalls noch thermisch stabili¬ siert, um die Makromoleküle auszurichten und dadurch der Borste die erforderliche Flexibilität bei ausreichender Steifigkeit zu verleihen. Diese Eigenschaften gehen bei einer nachträglichen thermischen Behandlung aufgrund der Reorientierung verloren.In the case of wire brushes and brushes, it is known to corrugate the wire pins used, but the focus here is on reasons of stability and the abrasive effect (US Pat. No. 1,178,179, DE-U-79 06 716). Furthermore, hairpin bristles are known (US Pat. No. 2,511,004) which are made of plastic, but whose shape should come as close as possible to the natural bristle. These bristles have a long-wave profile and are pointed at their ends. They are primarily intended for paintbrushes and paintbrushes. These bristles are produced by starting from an endless monofilament that is constricted at regular intervals by tensile forces. The bristles are then cut, in each case in the region of the constriction, so that a single bristle is formed with two pointed ends. This individual bristle is then passed through pairs of form rollers which are at right angles to one another and are arranged at a distance. In order to prevent the bristle from rotating axially when the shaping forces act, the shaping should be carried out with simultaneous application of heat. This is absolutely unacceptable for bristles, because when the bristles are formed from endless monofilaments, the monofilaments are stretched, possibly also thermally stabilized, in order to align the macromolecules and thereby give the bristle the necessary flexibility with sufficient rigidity. These properties are lost in subsequent thermal treatment due to the reorientation.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung der erfindungsgemäß ausgebildeten Borsten vorzuschlagen, bei dem die vorgenannten Nachteile vermie¬ den werden.The invention is based on the object of proposing a method for producing the bristles designed according to the invention in which the aforementioned disadvantages are avoided.
Das erfindungsgemäße Verfahren zeichnet sich deshalb dadurch aus, daß ein Kunststoff-Endlosmonofil durch die Formrollen hindurchgeführt und hinter den Formrollen auf einer Spule aufgewickelt wird, wobei das Monofil mit Bezug auf seine Achse durch die Spulen verdrehsicher gehalten wird, und daß die Borsten durch Ablängen des gewellten Endlosmonofils hergestellt werden.The method according to the invention is therefore characterized in that a continuous plastic monofilament is passed through the shaping rollers and wound up on a spool behind the shaping rollers, the monofilament being held against rotation by the spools with respect to its axis, and in that the bristles are cut to length wavy endless monofilament.
Vorzugsweise wird das Endlosmonofil mittels der Formrol¬ len von einer Spule abgezogen. Stattdessen ist es aber auch möglich, das Endlosmonofil nach seiner Erzeugung in einem Extruder den Formrollen zuzuführen. Die Wellung erfolgt ohne zusätzliche Wärmezufuhr von außen.The endless monofilament is preferably drawn off from a spool by means of the form rollers. Instead, however, it is also possible to feed the continuous monofilament to the form rolls after it has been produced in an extruder. The curl takes place without additional heat from the outside.
Vorzugsweise wird das Monofil zwischen wenigstens zwei mit geringstmöglichem Abstand unmittelbar hintereinander- liegenden Formrollen-Paaren hindurchgeführt, um die ausgeprägten Wellenscheitel irreversibel einzuformen.The monofilament is preferably passed between at least two pairs of form rollers lying one behind the other with the smallest possible spacing in order to irreversibly mold the pronounced wave apices.
Wird das Monofil zwischen zwei Formrollen-Paaren mit paarweise winklig zueinander angeordneten Achsen hin- durchgeführt, so läßt sich eine Wellung in zwei Ebenen erreichen. In gleicher Weise ist mittels drei Formrol¬ len-Paaren mit paarweise winklig zueinander stehenden Achsen eine Wellung in drei Ebenen möglich.If the monofilament is passed between two pairs of form rollers with axially arranged axes in pairs, a corrugation can be achieved in two planes. In the same way, corrugation in three planes is possible by means of three pairs of form rollers with axially mutually aligned axes.
Stattdessen können gleichzeitig mehrere Kunststoff-End¬ losmonofile mit Abstand nebeneinander geführt mittels der Formrollen von einer Spule abgezogen und hinter den Formrollen auf einer Spule aufgewickelt werden, wobei auch hier das einzelne Monofil mit Bezug auf seine Achse verdrehsicher gehalten wird.Instead, a plurality of endless plastic monofilaments can be drawn from one spool at a distance next to one another by means of the shaping rollers and wound up on a spool behind the shaping rollers, the individual monofilament also being held against rotation with respect to its axis.
In bevorzugter Ausführung ist vorgesehen, daß das Endlos¬ monofil zwischen Formrollenpaaren von 10 bis 20mm, deren Achsabstand voneinander etwa gleich groß ist, hindurchge- führt werden.In a preferred embodiment it is provided that the endless monofilament is passed between pairs of form rollers of 10 to 20 mm, the center distance of which is approximately the same.

In Figur 1 ist eine Bürste zur Zahnfleischmassage und Zahnreinigung gezeigt, die aus einem Griff 1, einem als Borstenträger dienenden Kopf 2 und einer Vielzahl einzeln stehender Borsten 3 gebildet ist. Die Borsten 3 können gegebenenfalls auch zu Bündeln oder Paketen zusammenge¬ faßt sein. Sämtliche oder ein Teil der Borsten sind mit kurzer Wellenlänge gewellt . Ihre nutzungsseitigen Enden 4 können, wie beim gezeigten Ausführungsbeispiel, derFIG. 1 shows a brush for gum massage and tooth cleaning, which consists of a handle 1, a head 2 serving as a bristle holder and a large number of individual brushes standing bristles 3 is formed. The bristles 3 can optionally also be combined into bundles or packages. All or part of the bristles are wavy with a short wavelength. Your use-side ends 4 can, as in the embodiment shown, the

Es ist ohne weiteres ersichtlich, daß die warzenartigen Wellenscheitel Wirkkanten bei der Zahnfleischmassage bilden, wie dies in Figur 2 angedeutet ist. Es wird deshalb bei der Zahnfleischmassage vorzugsweise ein solcher Andruck ausgeübt, daß die Borsten aus ihrer gestreckten Lage ausgelenkt werden und die Wellenscheitel zur Wirkung kommen. Beim Putzen der Zähne hingegen kann mit diesem oder einem verminderten Andruck gearbeitet werden, so daß sich die Borsten aufstellen und die nutzungsseitigen Enden 4 zur Wirkung kommen. Aufgrund der Krümmung an den nutzungsseitigen Enden werden insbesonde¬ re auch die Zahnzwischenräume wirksam gereinigt .It is readily apparent that the wart-like crests form active edges during the gum massage, as indicated in FIG. 2. For gum massage, pressure is therefore preferably exerted in such a way that the bristles are deflected out of their extended position and the crest of the wave comes into effect. When brushing the teeth, however, can be worked with this or a reduced pressure, so that the bristles stand up and the user-side ends 4 come into effect. Because of the curvature at the ends on the usage side, the interdental spaces are also effectively cleaned.
In Figur 3 ist eine Borste 3 während der Benutzung der Bürste in vergrößertem Maßstab gezeigt. Es ist ersicht¬ lich, wie die warzenartigen Wellenscheitel nach Art von Massagenoppen auf das Zahnfleisch einwirken.FIG. 3 shows a bristle 3 on an enlarged scale during the use of the brush. It can be seen how the wart-like crests act on the gums in the manner of massage nubs.
Figur 4 zeigt eine vergrößerte Teilansicht einer Borste 3, die gleichmäßig sinusförmig gewellt ist, so daß war¬ zenartige Wellenscheitel 5 und Wellentäler 6 entstehen. Während die Wellenscheitel 5 die wirksamen Arbeitsflächen der Borste bilden, nehmen die Wellentäler 6 Zahnpflege¬ mittel od. dgl. auf. Die Borste gemäß Figur 4 kann einen Querschnitt gemäß Figur 5 aufweisen, also in zwei senk¬ recht zueinander stehenden Ebenen gewellt sein, so daß sich auf der Hüllfläche der Borste warzenartige Wellen- Scheitel 5 in Richtung aller vier Koordinaten erstrecken. In Figur 6 ist eine Borste mit abgewandelter Wellenform gezeigt . Die Wellenflanken verlaufen im wesentlichen geradlinig und die warzenartigen Wellenscheitel 5 weisen einen wesentlich kleineren Krümmungsradius auf. Bei dieser Ausführungsform entspricht die Wellenlänge etwa dem Borstendurchmesser, wie mit dem Buchstaben "D" ange¬ deutet .FIG. 4 shows an enlarged partial view of a bristle 3 which is corrugated uniformly in a sinusoidal manner, so that wart-like wave crests 5 and wave troughs 6 are formed. While the wave crests 5 form the effective working surfaces of the bristle, the wave troughs 6 accommodate dental care products or the like. The bristle according to FIG. 4 can have a cross section according to FIG. 5, that is to say it is corrugated in two mutually perpendicular planes, so that wart-like wave crests 5 extend on the envelope surface of the bristle in the direction of all four coordinates. FIG. 6 shows a bristle with a modified wave shape. The wave flanks run essentially in a straight line and the wart-like wave apexes 5 have a much smaller radius of curvature. In this embodiment, the wavelength corresponds approximately to the bristle diameter, as indicated by the letter "D".
Figur 7 zeigt eine Borste ähnlich der Figur 4 mit einer Wellenlänge die etwa dem doppelten Borstendurchmesser entspricht. Figur 8 wiederum zeigt eine Borste mit rela¬ tiv langgestreckter Welle und geradlinigen Flanken 7 und noch stärker ausgeprägten Wellenscheiteln 5 mit ganz geringem Krümmungsradius. Die Wellenlänge beträgt bei dieser Borste etwa das 4-fache des Borstendurchmessers.FIG. 7 shows a bristle similar to FIG. 4 with a wavelength that corresponds approximately to twice the bristle diameter. FIG. 8 in turn shows a bristle with a relatively elongated shaft and straight flanks 7 and even more pronounced shaft apices 5 with a very small radius of curvature. The wavelength of this bristle is about 4 times the bristle diameter.
In den Figuren 13 und 14 ist eine Vorrichtung zur Durch¬ führung des erfindungsgemäßen Verfahrens schematisch angedeutet. Sie weist eine Vorratsspule 10 auf, auf der ein Endlosmonofil 11 aus Kunststoff aufgespult ist. Ferner weist sie eine Sammelspule 12 zur Aufnahme des gewellten Monofils 13 auf. Das Monofil 11 durchläuft drei hinter¬ einander angeordnete Formrollen bzw. Formwalzen-Paare 14, 15 und 16, die an ihrem Umfang entsprechend der gewünsch¬ ten Wellenform (Figuren 4 bis 8) profiliert sind. Die Achsen der Formrollenpaare 14, 15 und 16, von denen die Achsen wenigstens eines Paares angetrieben sind, sind unmittelbar hintereinander angeordnet, so daß sie sich gerade nicht berühren. Sie sind ferner um jeweils 60° gegeneinander gedreht, wie aus Figur 14 ersichtlich.A device for performing the method according to the invention is indicated schematically in FIGS. 13 and 14. It has a supply spool 10 on which an endless monofilament 11 made of plastic is wound. It also has a collecting coil 12 for receiving the corrugated monofilament 13. The monofilament 11 runs through three form rollers or pairs of form rollers 14, 15 and 16 arranged one behind the other, which are profiled on their circumference in accordance with the desired wave shape (FIGS. 4 to 8). The axes of the pairs of form rollers 14, 15 and 16, of which the axes of at least one pair are driven, are arranged directly one behind the other so that they do not touch each other. They are also rotated against each other by 60 °, as can be seen from FIG. 14.
Die Formrollen weisen vorzugsweise einen Durchmesser von 10 bis 20mm auf und der Abstand ihrer Achsen voneinander, wie auch der Achsen der benachbarten Formrollenpaare 14, 15 und 16 ist nur unwesentlich, nämlich etwa um den Monofildurchmesser größer. Auf diese Weise wird ein gewelltes Monofil 13 erhalten, dessen Wellenscheitel in drei verschiedenen Axialebenen der Borste liegen. The form rollers preferably have a diameter of 10 to 20 mm and the distance of their axes from each other, as well as the axes of the adjacent pairs of form rollers 14, 15 and 16, is only insignificant, namely about the Monofilament diameter larger. In this way, a corrugated monofilament 13 is obtained, the crest of which lies in three different axial planes of the bristle.
