Description
Die Erfindung betrifft eine Bürste zur Zahnfleischmassage und Zahnreinigung, bestehend aus einem Borstenträger mit Griff und am Borstenträger einzeln oder in Bündeln befestigten Borsten aus Kunststoff.The invention relates to a brush for gum massage and tooth cleaning, consisting of a bristle holder with Handle and attached to the bristle holder individually or in bundles Bristles made of plastic.
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 not only includes tooth cleaning, but also the gum massage Prevention of gingivitis, periodontal disease, etc. Toothbrushes usual type, whether manually or electrically driven, do the job of cleaning teeth sufficiently, but not that of the gum massage, in particular if both effects on a single trajectory should be achieved. So for teeth cleaning, especially the interdental spaces, the bristle ends particularly effective, but often for gum massage too aggressive, especially if they are not working properly are rounded or flattened by use. For the gum massage, however, the pressure should be and the trajectory are chosen so that the Fold bristles and with their outer surface a kind Effect stroke massage. But they are in this position in turn, far less effective and for tooth cleaning even unsuitable for cleaning the 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 jedenfalls zwei Arbeitsgänge durchzuführen, gegebenenfalls sogar zwei verschiedene Geräte zu verwenden. Dies ist umständlich mit der Folge, daß sich solche Zahnfleischmassagegeräte nicht einführen konnten.An effective gum massage is therefore only with Special equipment possible, their work surface usually consists of rubber-elastic materials and nub-like is profiled (GB 398 919, US 1 892 068). These devices are now completely unsuitable for cleaning teeth. It is therefore for complete oral hygiene in any case perform two operations, if necessary even use two different devices. This is cumbersome with the result that such gum massagers could not introduce.
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 unterschiedlichen Borstenbereiche zu den ihnen zugeordneten Behandlungsbereichen -Zahn oder Zahnfleisch- durch den Benutzer nicht ohne weiteres möglich ist. Zudem wird dieser Kompromiß jeweils durch Minderung der einen Wirkung auf Kosten der anderen geschlossen.Toothbrushes are also known in practice Bristle trim in the different directions Brushing the teeth and massaging the gums adapted is. Such a toothbrush has one in comparison hard medium trimmings and more flexible outdoors Massage bristles on. This is inevitable to a compromise, the allocation of different Bristle areas to the treatment areas assigned to them -Tooth or gums- by the user is not easily possible. In addition, this compromise each by reducing the one effect Cost of the other closed.
Diesem Prinzip folgt eine bekannte Zahnbürste (DE-U-295 01 338), bei der neben üblichen geradlinigen Borsten Polfäden am Borstenträger befestigt sind. Polfäden sind schlaffe Textilfasern, die bei dieser Zahnbürste durch thermisches Schrumpfen gekräuselt sind. Diese Polfäden können keine Reinigungswirkung wie Borsten entfalten.A known toothbrush follows this principle (DE-U-295 01 338), in addition to the usual straight bristles Pole threads are attached to the bristle holder. Are pile threads flaccid textile fibers that go through with this toothbrush thermal shrinkage are curled. These pile threads cannot develop a cleaning effect like bristles.
Der Erfindung liegt die Aufgabe zugrunde, eine Bürste zur Zahnfleischmassage vorzuschlagen, die gleichermaßen effektiv die Zahnreinigung besorgt.The invention has for its object a brush for Propose gum massage that equally effectively doing teeth cleaning.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Borsten unter Bildung ausgeprägter, warzenartiger Wellenscheitel mit kurzer Wellenlänge quer zur ihrer Achse gewellt sind. This object is achieved in that the bristles are more pronounced, wart-like Wave crests with a short wavelength transverse to theirs Axis are wavy.
Die erfindungsgemäß ausgebildete Borste weist, wie jede herkömmliche Borste ein verrundetes Arbeitsende auf, das gleichermaßen für die Zahnreinigung und für die Zahnfleischmassage -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 Zahnfleischs. Bei entsprechendem Andruck des Borstenbesatzes, bei dem sich die Borsten umlegen, sind also an jeder einzelnen im Eingriff befindlichen Borste zugleich mehrere Wellenscheitel reinigend und/oder massierend wirksam. Es lassen sich also in einem Arbeitsgang mit einem einzigen Gerät die für eine einwandfreie Mundhygiene notwendigen Maßnahmen durchführen.The bristle designed according to the invention, like any other conventional bristle has a rounded working end that equally for cleaning teeth and for gum massage - acts as a kind of massage finger. In addition, the unavoidable transfer of the Bristle the wart-like crest in a similar way Wise act like the bristle ends, both at teeth cleaning, as well as gum massage. With appropriate pressure on the bristle trim, in which the bristles fold, so are on everyone individual engaged bristle several at the same time Wave crest cleansing and / or massaging effect. So it can be done in a single pass Device the necessary for proper oral hygiene Take action.
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 Borstenbesatz tropfen solche Gele aufgrund ihrer geringen Viskosität 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, they become labyrinthine Channels formed between the individual bristles in which Dental care products are stored excellently. This applies in particular to the gels frequently used today, which are pressed into the gaps during application can be. For toothbrushes with conventional bristles Such gels drip due to their low viscosity frequently and lead to corresponding losses. On the other hand, such a brush can be easily rinsed out and dry the bristles and bristle spaces also quickly, so that dirt and bacteria are not can 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 in two or more levels corrugated, which ensures that regardless of how the bristle turns when cleaning, wart-like crests always come into effect.
Während bei einem üblichen Kreisquerschnitt einer Borste die Wellenscheitel mehr oder weniger abgerundet sind, können bei einem von der Kreisform abweichenden Querschnitt einerseits bevorzugte Biegeebenen erzeugt werden, andererseits die Wellenscheitel stärker ausgeprägt werden. So können die Borsten beispielsweise einen ovalen Querschnitt, vorzugsweise aber einen polygonalen Querschnitt 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 crests are more or less rounded, can with a cross-section deviating from the circular shape on the one hand, preferred bending planes are generated, on the other hand, the wave crests are more pronounced. For example, the bristles can be oval Cross section, but preferably a polygonal cross section with rounded longitudinal edges. As polygonal cross section is particularly useful cross-shaped 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 determined by the geometry of the individual shaft influence. For example, the wavelength can be 1 to 10 times the bristle diameter, but is advantageously between 1 and 5 times. In In a preferred embodiment, the wavelength is smaller than twice the bristle diameter.
Ferner sollte die Wellenhöhe, d.h. der Abstand gegenüberliegender Wellenscheitel, möglichst klein sein. Vorzugsweise beträgt er das 1,2- bis 2-fache des Borstendurchmessers.Furthermore, the wave height, i.e. the distance opposite Wave crest, be as small as possible. Preferably it is 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 crest of the wave is from Meaning, with angular wave crests are 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 bestehen, jedoch in ihrer Form der Naturborste möglichst nahe kommen sollen. Diese Borsten sind langwellig profiliert und an ihren Enden zugespitzt. Sie sind in erster Linie für Pinsel und Malerbürsten bestimmt. Die Herstellung 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, hindurchgeführt. Um ein axiales Verdrehen der Borste bei Einwirken der Umformkräfte zu vermeiden, soll das Umformen unter gleichzeitiger Anwendung von Wärme erfolgen. Dies ist bei Borsten absolut unzuträglich, denn bei der Bildung der Borsten aus Endlosmonofilen werden die Monofile verstreckt, gegebenenfalls noch thermisch stabilisiert, 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.It is known for wire brushes and brushes that to use used wire pins, but stand here Reasons for stability and the abrasive effect in the foreground (US 1 178 179, DE-U-79 06 716). Furthermore, hairpin bristles known (US 2,511,004), which consist of plastic, however in their natural bristle form if possible should come close. These bristles are profiled with long waves and pointed at their ends. You are in the first Line designed for paintbrushes and paintbrushes. The production this bristle is made in that starting from an endless monofilament of this at regular intervals is constricted by tensile forces. Then be cut the bristles, each in the area the constriction so that a single bristle with two tapered ends is formed. This single bristle is then replaced by perpendicular to each other Form roller pairs, which are arranged at a distance, passed through. To axially twist the bristle The aim is to avoid the influence of the forming forces with simultaneous application of heat. This is absolutely unacceptable with bristles, because with the Formation of the bristles from endless monofilaments becomes the monofilaments stretched, if necessary still thermally stabilized, to align the macromolecules and thereby the Bristle has the required flexibility with sufficient To give stiffness. These characteristics go with a subsequent thermal treatment due to the Reorientation lost.
Bei der Herstellung schlaffer Textilfasern ist es bekannt (US-A-3 425 206), ein Multifilament, das abschnittsweise gekräuselt ist, durch verzahnte Formrollen zu ziehen, um das Garn zu krimpen. Dabei kommt es weder auf die Exaktheit der Krimpung, noch auf die Lage gegenüber der Garnachse an.It is known in the manufacture of flaky textile fibers (US-A-3 425 206), a multifilament which is sectionally is curled to pull through toothed form rollers to crimp the yarn. It does not depend on the exactness the crimp, still on the position opposite the Garnachse on.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung der erfindungsgemäß ausgebildeten Borsten vorzuschlagen, bei dem die vorgenannten Nachteile vermieden werden.The invention has for its object a method for the production of the bristles designed according to the invention to propose, in which the aforementioned disadvantages are avoided become.
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 distinguished characterized in that a continuous plastic monofilament through the Form rollers passed through and behind the form rollers a spool is wound, the monofilament with Relative to its axis by the coils against rotation is held, and that the bristles by cutting the wavy endless monofilament.
Vorzugsweise wird das Endlosmonofil mittels der Formrollen 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 made by means of the forming rolls withdrawn from a spool. Instead it is also possible to create the endless monofilament in to feed the form rolls to an extruder. The curl takes place without additional heat from the outside.
Vorzugsweise wird das Monofil zwischen wenigstens zwei mit geringstmöglichem Abstand unmittelbar hintereinanderliegenden Formrollen-Paaren hindurchgeführt, um die ausgeprägten Wellenscheitel irreversibel einzuformen.The monofilament is preferably between at least two with the smallest possible distance immediately behind one another Form roller pairs passed to the to form a pronounced wave crest irreversibly.
Wird das Monofil zwischen zwei Formrollen-Paaren mit paarweise winklig zueinander angeordneten Achsen hindurchgeführt, so läßt sich eine Wellung in zwei Ebenen erreichen. In gleicher Weise ist mittels drei Formrollen-Paaren mit paarweise winklig zueinander stehenden Achsen eine Wellung in drei Ebenen möglich.If the monofilament between two pairs of form rollers with led through in pairs at an angle to each other, so there can be a curl in two planes to reach. In the same way is by means of three pairs of form rollers with pairs at an angle to each other Axes can be curled in three planes.
Stattdessen können gleichzeitig mehrere Kunststoff-Endlosmonofile 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, several continuous plastic monofilaments can be used at the same time spaced apart by means of the Pulled form rolls from a spool and behind the Form rolls are wound on a spool, whereby here too the single monofilament with reference to its axis is held against rotation.
In bevorzugter Ausführung ist vorgesehen, daß das Endlosmonofil zwischen Formrollenpaaren von 10 bis 20mm, deren Achsabstand voneinander etwa gleich groß ist, hindurchgeführt werden.In a preferred embodiment it is provided that the endless monofilament between pairs of form rollers from 10 to 20mm, whose Center distance from each other is approximately the same size, passed become.

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 zusammengefaßt
sein. Sämtliche oder ein Teil der Borsten sind mit
kurzer Wellenlänge gewellt. Ihre nutzungsseitigen Enden 4
können, wie beim gezeigten Ausführungsbeispiel, der
Wellenform folgend aus der Borstenachse abgebogen sein.In Figure 1 is a brush for gum massage and
Dental cleaning shown, which consists of a
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 insbesondere auch die Zahnzwischenräume wirksam gereinigt.It is readily apparent that the wart-like Wave crest active edges during gum massage form as indicated in Figure 2. It will therefore preferably a gum massage exerted such pressure that the bristles from her stretched position and the crest of the wave come into effect. When brushing the teeth, however, can worked with this or a reduced pressure be so that the bristles stand up and the use ends 4 come into effect. Due to the Curvature at the ends on the usage side will be particular 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 ersichtlich,
wie die warzenartigen Wellenscheitel nach Art von
Massagenoppen auf das Zahnfleisch einwirken.In Figure 3 is a
Figur 4 zeigt eine vergrößerte Teilansicht einer Borste

Wellenscheitel 5 und Wellentäler 6 entstehen.
Während die Wellenscheitel 5 die wirksamen Arbeitsflächen
der Borste bilden, nehmen die Wellentäler 6 Zahnpflegemittel
od. dgl. auf. Die Borste gemäß Figur 4 kann einen
Querschnitt gemäß Figur 5 aufweisen, also in zwei senkrecht
zueinander stehenden Ebenen gewellt sein, so daß
sich auf der Hüllfläche der Borste warzenartige Wellenscheitel
5 in Richtung aller vier Koordinaten erstrecken. Figure 4 shows an enlarged partial view of a
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" angedeutet.In Figure 6 is a bristle with a modified wave shape

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 relativ 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.Figure 7 shows a bristle similar to Figure 4 with a Wavelength about twice the bristle diameter corresponds. Figure 8 in turn shows a bristle with relative elongated shaft and straight flanks 7 and even more pronounced wave crests 5 with whole small radius of curvature. The wavelength is at this bristle is about 4 times the bristle diameter.

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 hintereinander
angeordnete Formrollen bzw. Formwalzen-Paare 14,
15 und 16, die an ihrem Umfang entsprechend der gewünschten
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.In Figures 13 and 14 is a device for performing
of the method according to the invention schematically
