Description

Die Erfindung betrifft eine Bürste, insbesondere Zahnbürste, die an einem Ende an einem Behälter mit einer Dosierpumpe befestigbar ist und eine Bürste-Behälter-Kombination mit einer derartigen Bürste sowie einem Behälter mit einer Dosierpumpe.The invention relates to a brush, in particular toothbrush, the one end to a container with a metering pump can be fastened and a brush-container combination with such a brush and a container with a metering pump.

Aus dem Stand der Technik (GB 2 194 728 A, GB 2 215 593 A) ist es bekannt, Zahnbürsten direkt an Zahnpastatuben zu befestigen, wobei mittels an der Zahnpastatube angeordneten Pumpvorrichtungen Zahnpasta durch einen Auslaßkanal in der Zahnbürste in den Bereich des Bürstenkopfes gepumpt werden kann. Nachteilig bei derartigen Zahnbürsten-Behälter-Kombinationen ist, daß für das Pumpen durch den relativ langen Auslaßkanal in der Zahnbürste und durch die zähflüssige Zahnpasta ein relativ hoher Kraftaufwand zum Betätigen der Pumpe erforderlich ist, der es insbesondere für schwächere Personen schwer oder unmöglich macht, Zahnpasta aus der Tube zum Bürstenkopf zu pumpen bzw. dies genau dosiert durchzuführen.It is known from the prior art (GB 2 194 728 A, GB 2 215 593 A) known to attach toothbrushes directly to toothpaste tubes, wherein Toothpaste by means of pumping devices arranged on the toothpaste tube through an outlet channel in the toothbrush in the area of Brush head can be pumped. A disadvantage of such Toothbrush Container Combinations is that for pumping through the relatively long outlet channel in the toothbrush and by the viscous Toothpaste a relatively high force to operate the Pump is required, especially for weaker persons difficult or impossible, toothpaste from the tube to the brush head to pump or perform this precisely metered.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Bürste und eine Bürsten-Behälter-Kombination zur Verfügung zu stellen, welche die erwähnten Nachteile weitgehend vermeiden.The invention is therefore based on the object, a brush and a To provide brush container combination, which the largely avoid the mentioned disadvantages.

Gelöst wird diese Aufgabe mit einer Bürste mit den Merkmalen des Anspruches 1 sowie mit einer Bürsten-Behälter-Kombination mit den Merkmalen des Anspruches 4.This problem is solved with a brush with the characteristics of the Claim 1 and with a brush-container combination with the Features of claim 4.

Die Erfindung macht sich den Umstand zunutze, daß durch die Bürste, insbesondere eine Zahnbürste, ein relativ langer Hebelarm zur Verfügung gestellt wird, mit dem die Pumpbewegung relativ zum Behälter ausgeführt werden kann, wobei durch die Anlagefläche an der Bürste die Dosierpumpe am Behälter betätigt wird. Durch den langen Hebelarm an der Bürste wird der erforderliche Kraftaufwand zum Ausführen der Pumpbewegung erheblich reduziert und wenn der Angriffspunkt am äußersten Ende der Bürste erfolgt, steht auch ein relativ langer Kraftweg zur Verfügung, der ein exaktes Dosieren ermöglicht.The invention makes use of the fact that through the brush, in particular a toothbrush, a relatively long lever arm available is placed, with the pumping movement relative to the container can be performed, wherein by the contact surface on the brush the metering pump is actuated on the container. Through the long lever arm on the brush is the force required to perform the Pumping movement significantly reduced and when the point of attack on the end of the brush is done, is also a relatively long Kraftweg available that allows precise dosing.

Es wird festgehalten, daß die vorliegende Erfindung nicht auf Zahnbürsten und Zahnpastabehälter beschränkt ist, sondern auch für beliebige andere Einsatzzwecke Verwendung finden kann, wobei lediglich beispielhaft z.B. Bürsten zum Auftragen von Schuhcreme oder kleine Bürsten zum Auftragen von Wimperntusche erwähnt werden. Es versteht sich, daß anstelle des Bürstenkopfes, wie er z.B. bei Zahnbürsten Verwendung findet, auch beliebige andere Einrichtungen zum Auftragen des flüssigen oder pastösen Mittels, wie z.B. Schwämmchen oder spachtelförmige Einrichtungen zum Einsatz kommen können.It should be noted that the present invention is not limited to toothbrushes and toothpaste container is limited, but also for Any other purposes can be used, with only for example, e.g. Brushes for applying shoe polish or small brushes for applying mascara are mentioned. It it will be understood that instead of the brush head, as e.g. at Toothbrushes use, including any other facilities for applying the liquid or pasty agent, e.g. thrush or spatula-shaped devices can be used.

Weitere Merkmale und Vorteile der vorliegenden Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispieles der Erfindung mit Bezug auf die Zeichnung.Other features and advantages of the present invention will be apparent from the subclaims and the description below a preferred embodiment of the invention with reference to the drawing.

In der Zeichnung ist im Längsschnitt eine Zahnbürste 18 dargestellt, die an einem Ende einen Bürstenkopf 17 sowie einen den Schaft der Zahnbürste 18 in Längsrichtung durchsetzenden und im Bereich des Bürstenkopfes 17 mündenden Kanal 11 aufweist. Am dem Bürstenkopf 17 gegenüberliegenden Ende 9 ist die Zahnbürste 18 mit einem etwa zylindrischen Zahnpastabehälter 1 verbunden. Der Behälter 1 weist an seinem der Zahnbürste 18 zugeordneten Ende einen Hals 14 mit einer Ausgabeöffnung 5 auf. An seinem Außenumfang ist der Hals 14 mit einem Gewinde 21 versehen. Die Zahnbürste 18 weist in Verlängerung des Kanales 11 am Ende 9 eine dem Hals 14 entsprechend geformte Ausnehmung sowie ein Innengewinde auf und kann somit auf den Hals 14 aufgeschraubt werden. Eine derartige Schraubverbindung ermöglicht ein einfaches Befestigen und Abnehmen der Zahnbürste 18 am Behälter 1, so daß der Behälter 1 bzw. die Zahnbürste 18 bei Bedarf leicht ausgetauscht werden können.In the drawing, a toothbrush 18 is shown in longitudinal section, at one end a brush head 17 and a shaft of the Toothbrush 18 penetrating in the longitudinal direction and in the area of Brush head 17 opening channel 11 has. At the brush head 17 opposite end 9 is the toothbrush 18 with an approximately cylindrical toothpaste container 1 connected. The container 1 indicates his the toothbrush 18 associated end a neck 14 with a Output opening 5 on. At its outer periphery of the neck 14 with a thread 21 provided. The toothbrush 18 points in extension the channel 11 at the end 9 a neck 14 correspondingly shaped Recess and an internal thread and can thus on the neck 14th be screwed on. Such a screw connection allows a simple attachment and removal of the toothbrush 18 on the container 1, so that the container 1 and the toothbrush 18, if necessary, easily can be exchanged.

Insbesondere dann, wenn es nicht unbedingt erforderlich ist, daß die Zahnbürste 18 und der Behälter 1 wieder voneinander getrennt werden müssen, sind auch andere Formen der Verbindung, wie z.B. eine Prellverbindung oder ein Verkleben von Zahnbürste 18 und Behälter 1 denkbar.In particular, if it is not absolutely necessary that the Toothbrush 18 and the container 1 are separated again are also other forms of the compound, such. a bounce connection or sticking of toothbrush 18 and container 1 conceivable.

Im dargestellten Ausführungsbeispiel weist der Behälter 1 eine Membranpumpe auf, die von einem Dom 13, an dem auch der Hals 14 angeordnet ist, sowie einer vom Dom 13 beabstandeten Trennwand 4 gebildet ist. Der Dom 13 schließt an eine etwa zylinderförmige Wand 22 des zylindrischen Behälters 1 an und ist elastisch deformierbar ausgeführt, so daß er durch eine Pumpbewegung mit Hilfe der Zahnbürste 18 elastisch deformiert werden kann, wie in der Folge noch beschrieben werden wird.In the illustrated embodiment, the container 1 has a Membrane pump on, by a dome 13, on which also the neck 14 is arranged, as well as a distance from the dome 13 partition 4 is formed. The dome 13 connects to an approximately cylindrical wall 22 of the cylindrical container 1 and is elastically deformable executed so that he by a pumping motion with the help of the toothbrush 18 can be elastically deformed, as in the episode yet will be described.

Die Trennwand 4 unterteilt den Innenraum im Behälter 1 in einen Pumpenraum 12 zwischen Dom 13 und Trennwand 4 sowie einen Speicherraum 7 zwischen Trennwand 4 und einem in der Zeichnung nicht dargestellten Boden des Behälters 1. In der Trennwand 4 ist ein Ventil angeordnet, das nur in Richtung vom Speicherraum 7 zum Pumpenraum 12 durchströmt werden kann.The partition 4 divides the interior in the container 1 in a Pump chamber 12 between Dom 13 and partition 4 and a storage space 7 between the partition 4 and a not shown in the drawing Bottom of the container 1. In the partition 4 is a valve arranged, only in the direction of the storage space 7 to the pump room 12th can be flowed through.

Um einen Pumpvorgang durchführen zu können, weist die Zahnbürste 18 eine Anlagefläche 23 auf, die im Bereich des Endes 9 und auf der gleichen Seite wie der Bürstenkopf 17 an der Zahnbürste 18 angeordnet ist. Wird die Zahnbürste in Richtung des Pfeiles 20 relativ zum Behälter 1 verschwenkt, deformiert sich der Dom 13 im Bereich des Halses 14 elastisch und die Anlagefläche 23 drückt zusätzlich den Dom 13 nach innen, so daß der Pumpenraum 12 verkleinert wird. Da das Ventil 10 nicht zum Speicherraum 7 hin von Zahnpasta durchströmt werden kann, sondern beim Beginn der Pumpbewegung sofort.in Pfeilrichtung 6 schließt, wird Zahnpasta durch die Ausgabeöffnung 5 und den Kanal 11 in Pfeilrichtung 19 zum Bürstenkopf 17 gepumpt. Läßt man die Zahnbürste 18 aus, wird diese durch die im Dom 13 gespeicherte Formänderungskraft zurückbewegt, wobei sich das Volumen des Pumpenraumes 12 wieder vergrößert. Damit nicht Zahnpasta in einem nennenswerten Ausmaß durch den Kanal 11 zurückgesaugt wird, sind der Kanal 11 hinsichtlich seiner Länge, seines Durchmessers und seiner Rauheit einerseits und das Ventil 10 anderseits so ausgelegt, daß Zahnpasta vornehmlich vom Speicherraum 7 durch das Ventil 10 in den Pumpenraum 12 nachgesaugt wird. Dadurch, daß der Kanal 11 relativ lange und mit geringem Querschnitt ausgeführt ist, wogegen das Ventil 10 mit einem großen Durchlaßquerschnitt ausgestattet sein soll, ist dies ohne weiteres zu bewerkstelligen, so daß ein den Pumpenraum 12 in Richtung zur Zahnbürste 18 hin verschließendes Ventil entbehrlich ist.In order to carry out a pumping operation, the toothbrush 18 a contact surface 23 which in the region of the end 9 and on the same side as the brush head 17 is arranged on the toothbrush 18 is. If the toothbrush in the direction of arrow 20 relative to Container 1 pivots, deforms the dome 13 in the region of Neck 14 elastic and the contact surface 23 additionally pushes the Dom 13 inside, so that the pump chamber 12 is reduced. Since that Valve 10 is not flowed through to the storage space 7 through toothpaste can be, but at the beginning of the pumping movement immediately in the direction of the arrow 6 closes, toothpaste is passed through the dispensing opening 5 and the channel 11 is pumped in the direction of arrow 19 to the brush head 17. Leaves one toothbrush 18, this is stored by the in the cathedral 13 Forming force moves back, whereby the volume of the Pump chamber 12 again enlarged. So not toothpaste in one be sucked back to a significant extent through the channel 11, the Channel 11 in terms of its length, diameter and its Roughness on the one hand and the valve 10 on the other hand designed so that Toothpaste primarily from the storage space 7 through the valve 10 in the Pump chamber 12 is sucked. Characterized in that the channel 11 relative long and with a small cross section is executed, whereas the Valve 10 may be equipped with a large flow area This is easily accomplished, so that the one Pump chamber 12 in the direction of the toothbrush 18 towards closing Valve is dispensable.

Aus Hygienegründen und um ein Austrocknen von Zahnpasta im Bereich der Ausgangsöffnung 15 des Kanals 11 im Bereich des Bürstenkopfes 17 zu verhindern, kann dennoch im Bereich der Ausgangsöffnung 15 ein Ventil 16, z.B. in Form eines Gummiplättchens, vorgesehen sein, das sich nach Beendigung des Auspreßvorganges bzw. nach Reinigung des Bürstenkopfes 17 dichtend an die Ausgangsöffnung 15 anlegt und diese verschließt. Bei dünnflüssigen Mitteln kann mit dem Ventil 16 auch eine zuverlässige Pumpfunktion gewährleistet werden, damit das Mittel nicht im Kanal 11 zurückströmen kann.For reasons of hygiene and for drying out toothpaste in the area the exit opening 15 of the channel 11 in the region of the brush head 17th can still in the area of the outlet opening 15 a Valve 16, e.g. in the form of a rubber plate, be provided that after completion of the squeezing process or after cleaning the Brush head 17 sealingly applies to the output port 15 and this closes. For low-viscosity agents can also with the valve 16 a reliable pumping function can be ensured so that the Medium can not flow back in the channel 11.

Anstelle der in der Zeichnung dargestellten Dosierpumpe in Form einer Membranpumpe kann natürlich auch jede beliebige andere Form einer Dosierpumpe, z.B. eine Kolbenpumpe, verwendet werden, wobei der Kolben durch die Anlagefläche 23 betätigt würde.Instead of the dosing pump shown in the drawing in the form a membrane pump can of course also any other shape a metering pump, e.g. a piston pump, used the piston would be actuated by the contact surface 23.

Wie in der Zeichnung zu sehen ist, weist die Zahnbürste 18 im Bereich ihres Endes 9 eine kegelförmige Verbreiterung 24 auf, die an ihrer dem Behälter 1 zugewandten Seite eine Stützfläche 25 bildet. Am Dom 13 ist im Bereich des Überganges 26 von der Wand 24 eine korrespondierende Stützfläche 27 vorgesehen, die mit der Stützfläche 25 an der Zahnbürste 18 zusammenwirkt. Da der Dom 13 im Bereich des Überganges 26 einen hohen Formänderungswiderstand aufweist, wird verhindert, daß die Zahnbürste 18 bei der Benutzung gegen die Pfeilrichtung 20 verschwenkt wird. Da die Stützfläche 27 am Dom 13 rotationssymmetrisch ist und die Stützfläche 25 ebenfalls rotationssymmetrisch ist und nur von der Auflagefläche 23 unterbrochen wird, wird die Zahnbürste 18 auch seitlich neben der Auflagefläche 23 gut abgestützt, so daß auch ein seitliches Kippen bzw. Verschwenken der Zahnbürste 18 vermieden wird.As can be seen in the drawing, the toothbrush 18 in the area of their end 9 a conical broadening 24 on their side facing the container 1 forms a support surface 25. At the dome 13 is in the region of the transition 26 of the wall 24 a corresponding support surface 27 provided with the support surface 25 cooperates with the toothbrush 18. Since the cathedral 13 in the area of Transition 26 has a high deformation resistance is prevents the toothbrush 18 in use against the direction of the arrow 20 is pivoted. Since the support surface 27 on the dome 13 rotationally symmetrical is and the support surface 25 also rotationally symmetrical is and is interrupted only by the support surface 23, the toothbrush 18 is also good on the side next to the support surface 23 supported, so that a lateral tilting or pivoting of the Toothbrush 18 is avoided.

Grundsätzlich wäre es auch denkbar, daß die Zahnbürste 18 so ausgeführt ist, daß keine gesondert vorgesehene Auflagefläche während der Pumpbewegung am Dom 13 anliegt, da auch schon durch das elastische Deformieren des Domes 13 im Bereich um den Hals 14 während der Pumpbewegung eine Pumpwirkung eintritt. In diesem Fall stellt die Verbindungsfläche zwischen dem Ende 9 der Zahnbürste 18 und dem Hals 14 in Form des Gewindes 21 die Anlagefläche dar, wobei auch in diesem Fall die erfindungsgemäße Verschwenkbarkeit der Zahnbürste 18 relativ zum Behälter 1, d.h. die Verwendung der Zahnbürste 18 als Pumphebel, verwirklicht ist.In principle, it would also be conceivable for the toothbrush 18 to be designed in this way is that no separately provided support surface during the Pumping movement on the dome 13 is applied, as already by the elastic Deformation of the dome 13 in the area around the neck 14 during the Pumping a pumping effect occurs. In this case, the Connecting surface between the end 9 of the toothbrush 18 and the neck 14 in the form of the thread 21, the contact surface, wherein also in In this case, the pivotability of the toothbrush 18 according to the invention relative to the container 1, i. the use of the toothbrush 18 as Pump lever, is realized.

Gleichermaßen ist es denkbar, daß die Zahnbürste 18 über ein Gelenk mit dem Behälter 1 verbunden ist, so daß der Behälter 1 durch die Schwenkbewegung der Zahnbürste 18 nicht elastisch deformiert wird und über die Anlagefläche eine Pumpe, z.B. eine Kolbenpumpe oder Membranpumpe, betätigt wird.Similarly, it is conceivable that the toothbrush 18 via a joint is connected to the container 1, so that the container 1 through the Pivoting movement of the toothbrush 18 is not elastically deformed and over the contact surface a pump, e.g. a piston pump or Diaphragm pump, is actuated.

Der in der Zeichnunggn nicht dargestellte Boden des Behälters ist idealerweise ein an der Innenfläche 27 der Behälterwand 22 gleitender Teil, der durch geeignet ausgeformte Rippen an der Innenfläche 27 und/oder Krallen am Boden nur in Pfeilrichtung 8 zur Trennwand 4 hin bewegbar ist, wogegen eine Bewegung in die andere Richtung durch die Rippen und/oder Krallen verhindert wird, und durch Nachsaugen von Zahnpasta aus dem Speicherraum 7 in den Pumpenraum 12 automatisch nachgezogen wird.The bottom of the container, not shown in the drawing, is ideally a sliding on the inner surface 27 of the container wall 22 Part formed by suitably shaped ribs on the inner surface 27 and / or claws on the ground only in the direction of arrow 8 to the partition 4 towards, whereas a movement in the other direction by the ribs and / or claws is prevented, and by sucking toothpaste from the storage space 7 in the pump chamber 12 automatically is retraced.

Falls es bei einer z.B. neuen Zahnbürste 18 mit leerem Kanal 11 Probleme beim erstmaligen Pumpen von Zahnpasta gibt, kann der Kanal 11 durch Drücken auf den Boden wenigstens teilweise gefüllt werden, bis der Rückströmwiderstand im Kanal 11 so groß wird, bis Zahnpasta durch das Ventil 10 in den Pumpenraum 12 nachgesaugt wird.If it is at a e.g. new toothbrush 18 with empty channel 11 Problems when first pumping toothpaste gives the channel 11 are at least partially filled by pressing on the ground, until the backflow resistance in the channel 11 becomes so large until toothpaste is sucked through the valve 10 in the pump chamber 12.
