Description

Die Erfindung betrifft einen Spender zum Austragen eines fließfähigen Mediums nach dem Oberbegriff des Anspruchs 1.The invention relates to a dispenser for dispensing a flowable Medium according to the preamble of claim 1.

Für das Ausbringen, d.h. Spenden, von flüssigen, pastösen, gelartigen und pulverförmigen Medien aus Vorratsbehältern sind eine Vielzahl Spender bekannt. Dabei unterscheidet man zwei prinzipielle Systeme, das Pressen mittels Preßkolben und das Saugen mittels Pumpen. Im Bereich der Konsumartikel werden derartige Spender regelmäßig eingesetzt, wozu unter anderem Seifenspender, Parfümspender und Zahncremespender zählen.For spreading, i.e. Donate from liquid, pasty, gel-like and powdered media from storage containers are a variety of donors known. A distinction is made between two basic systems, the Pressing by means of plungers and suction by means of pumps. In the field of Such items are regularly used in consumer goods, for which purpose other soap dispensers, perfume dispensers and toothpaste dispensers.

Diese Spender werden heutzutage vielfach in Handhabungsgeräte eingebaut, was zur Folge hat, daß ein wiederholtes Nachfüllen des Vorratsbehälters mit fließfähigem Medium erwünscht ist. Ein Beispiel für ein solches Handhabungsgerät sind die Spenderzahnbürsten, wie in der DE 31 04 862 A1 beschrieben. Dort ist ein Zahnbürstengriff als Reservoirkörper für einen Zahnputzmittelvorrat vorgesehen, um Zahnputzmittel einem Zahnbürstenkopf bedarfsbezogen zuzuführen. Der Reservoirkörper enthält einen satt anliegenden Kolben mit einer mittigen, mit einem Gewinde versehenen Bohrung. Ein von einem Benutzer betätigbarer äußerer Schraubkopf trägt eine mit einem Gewinde versehene Stange, die mit der Bohrung in dem Kolben zusammenwirkt. Durch Drehung des Schraubkopfes wird der Kolben veranlaßt, sich an der Stange entlangzubewegen, so daß Zahnputzmittel ausgegeben wird. Nachteilig hierbei ist, daß die mit einem Gewinde versehene Kolbenstange stark kontaminationsanfällig ist und durch den Kolben Luft, Bakterien und Schmutz in das Zahnputzmittel gelangen können. Außerdem ist das Nachfüllen kompliziert und das System insgesamt sehr verschleißanfällig.These dispensers are now often installed in handling devices, which has the consequence that a repeated refilling of the storage container with flowable medium is desired. An example of one Handling devices are the donor toothbrushes, as in DE 31 04 862 A1 described. There is a toothbrush handle as a reservoir body for one Dentifrice stock provided to dentifrice a toothbrush head to be fed as needed. The reservoir body contains a snug one Piston with a central threaded bore. An outer screw head which can be operated by a user carries one with it a threaded rod that cooperates with the bore in the piston. By turning the screw head, the piston is caused to move along the bar so that dentifrice is dispensed becomes. The disadvantage here is that the threaded piston rod is highly susceptible to contamination and air from the piston, Bacteria and dirt can get into the dentifrice. Moreover refilling is complicated and the system as a whole is very susceptible to wear.

Aus der DE 44 30 583 A1 ist ein Zahnpastaspender mit Pumpe zum dosierten Auftragen von Zahnpasta bekannt, der aus zwei miteinander verschraubbaren Teilen, dem Pumpteil und dem Vorratsbehälter, besteht. Auf diese Weise ist der Vorratsbehälter nachfüllbar. Der Vorratsbehälter enthält einen Folgekolben, der in Richtung des Pumpteils gesaugt wird, wenn Zahnpasta aus dem Vorratsbehälter in den Pumpraum gesaugt wird. Wird der Vorratsbehälter erneut gefüllt, wird der Kolben des Vorratsbehälters bis zu einer bodenseitigen Kolbenstopnut gedrückt. Eine Nachfüllung ist auf diese Weise sauber und einfach möglich. Als nachteilig hat sich jedoch erwiesen, daß der Kolben in dem Vorratsbehälter verklebt, insbesondere dann, wenn das Zahnputzmittel weichpastös oder fließfähig ist.DE 44 30 583 A1 describes a toothpaste dispenser with a pump for metering Applying toothpaste known that consists of two screwable together Parts, the pumping part and the storage container. On in this way the reservoir can be refilled. The reservoir contains a follower piston which is sucked in the direction of the pump part, when toothpaste is sucked out of the reservoir into the pump room. If the reservoir is refilled, the piston of the reservoir becomes pressed down to a piston stop groove on the bottom. A refill is clean and easy to do. As a disadvantage proved, however, that the piston sticks in the reservoir, especially if the dentifrice is soft pasty or flowable is.

Aus der DE 38 37 704 C2 ist ein Pastenspender mit einer Dosierpumpe zur Abgabe dosierter Mengen pastöser Stoffe, wie Zahnpasta, Salben oder dergleichen aus Flaschen oder dosenartigen Pastenbehältern bekannt. In dem Pastenbehälter befindet sich ein Nachlaufkolgen, der von der offenen Bodenseite des Pastenbehälters her in diesen eingeführt ist. Durch das Ansaugen des pastösen Stoffes mittels der Dosierpumpe wird der Nachlaufkolgen ebenfalls angesaugt und befördert den in dem Pastenbehälter verbliebenen pastösen Stoff n Richtung Dosierpumpe. Auch bei dem hier beschriebenen Kolben besteht die Gefahr des Verklebens, wodurch die Funktionszuverlässigkeit des Pastenspenders stark eingeschränkt wird. DE 38 37 704 C2 describes a paste dispenser with a metering pump Dispensing dosed quantities of pasty substances such as toothpaste, ointments or the like known from bottles or can-like paste containers. By doing Paste container is a trailing flask from the open bottom side of the paste container is inserted into this. By suction of the pasty substance by means of the dosing pump becomes the trailing piston also sucked in and conveys the remaining in the paste container pasty substance in the direction of the metering pump. Even with the one described here Piston there is a risk of sticking, which increases the reliability of the paste dispenser is severely restricted.

Aufgabe der Erfindung ist es daher, einen Spender der genannten Art zu schaffen, der einfach aufgebaut und verschleißarm ist.The object of the invention is therefore to provide a donor of the type mentioned create that is simple and low-wear.

Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of the claim 1 solved.

Hierdurch wird ein Spender geschaffen, dessen Kolben als ein loses Einsatzteil schlüssig hinter einem Vorrat an fließfähigem Medium in dem Vorratsbehälter eingesetzt ist und dem fließfähigen Medium durch die Saugwirkung einer Austragvorrichtung schlüssig folgt, ohne daß Luft am Kolben vorbei in das zu spendende Medium eindringt. Es wird also ein geschlossenes System geschaffen, das zudem preiswert herstellbar ist. Da der Kolben aus einem Weich-Schaumstoff besteht, besitzt er eine schwammartige Elastizität, die bei einem geringfügigen Übermaß erlaubt, daß der Kolben unter leichtem Druck an der Innenwand des Vorratsbehälters anliegt. Durch die Wahl von Material und Materialstruktur ist der Kolben leicht und klebt auch bei längerem Lagern nicht an der Innenwand des Vorratsbehälters. Der Kolben wird also bei einer Ausgabe des fließfähigen Mediums als am Medium anhaftender Boden mitgezogen. Die Abnutzung eines solchen wiederholt einsetzbaren Kolbens ist gering.This creates a dispenser whose plunger is a loose insert conclusively behind a supply of flowable medium in the Storage container is used and the flowable medium through the Suction of a discharge device follows conclusively without air on Piston penetrates into the medium to be dispensed. So it becomes a closed one System created that is also inexpensive to manufacture. There the piston is made of a soft foam, it has a sponge-like Elasticity which, with a slight excess, allows the Piston abuts the inner wall of the storage container under slight pressure. The choice of material and material structure is the piston light and does not stick to the inside wall of the Reservoir. So the piston becomes flowable when dispensing The medium is pulled along as a base adhering to the medium. The wear such a repeatedly usable piston is small.

Besonders vorteilhaft ist bei diesem Spender ferner, daß der Kolben wegen seiner elastischen Verformbarkeit auch entlang von Krümmungsbereichen bewegbar ist. Als Vorratsbehälter können deshalb auch solche eingesetzt werden, die Kurven- oder Krümmungsabschnitte aufweisen. Ferner kann der Kolben an beliebige Vorratsbehälterquerschnitte angepaßt werden.It is also particularly advantageous in this dispenser that the piston because its elastic deformability also along areas of curvature is movable. Therefore, such can also be used as storage containers that have curve or curvature sections. Further the piston can be adapted to any cross-section of the reservoir.

Bevorzugt ist, daß der Kolben eine schrumpelige Umfangsfläche aufweist, da diese eine Labyrinthabdichtung an der Vorratsbehälterinnenwand bewirkt. Eine solche schrumpelige Umfangsfläche erlaubt, daß der Kolben einfach in den Vorratsbehälter eingesetzt werden kann, da die in dem Vorratsbehälter enthaltene Luft zunächst noch entweichen kann. Kontaktiert der Kolben das auszutragende Medium, so füllen sich die verschiedenen Rillen der schrumpeligen Umfangsfläche mit diesem Medium, was zu einem luftdichten Abschluß führt. Die schrumpelige Umfangsfläche ist vorzugsweise feinrillig durch Verwendung eines feinporigen Weich-Schaumstoff, dessen geschlossene Poren an der Umfangsfläche Unebenheiten erzeugen, die in ihrer Gesamtheit eine Schrumpeligkeit zur Folge haben.It is preferred that the piston has a shrinking peripheral surface, since this creates a labyrinth seal on the inner wall of the storage container. Such a wrinkled peripheral surface allows the piston can be easily inserted into the storage container because the in the Air contained in the reservoir can still escape. contacted the piston the medium to be discharged, the various fill up Grooving the wrinkled peripheral surface with this medium leads to leads to an airtight seal. The crumpled peripheral surface is preferably finely grooved by using a fine-pored soft foam, whose closed pores create unevenness on the peripheral surface, which, as a whole, result in shriveliness.

Der als Kolben eingesetzte Schaumstoffabschnitt wird vorzugsweise durch Ablängen von einem Strang erhalten. Damit die dem fließfähigen Medium zugewandte Ablängseite eine geschlossenporige Oberfläche aufweist, erfolgt das Ablängen vorzugsweise durch Thermoschnitt. Hierdurch wird bewirkt, daß das fließfähige Medium sich nicht in offene Poren des Kolbens anlagern kann.The foam section used as a piston is preferably through Preserve cut to length. So that the flowable medium facing longitudinal side has a closed-pore surface, takes place cutting to length preferably by thermal cutting. This causes that the flowable medium is not in the open pores of the piston can accumulate.

Der Kolben kann ein Ablängstück eines extrudierten Schaumstoffstranges sein. Seine Herstellung ist damit billig und schnell. Der Kolben kann auch eine ballige Gestalt besitzen, da eine solche Form die Gleitfähigkeit des Kolbens in Krümmungsabschnitten weiter verbessert.The piston can be a cut to length of an extruded foam strand his. It is therefore cheap and quick to manufacture. The piston can also have a spherical shape, since such a shape is the lubricity of the piston in curved sections further improved.

Als Schaumstoffmaterialien bevorzugt sind Polyethylen oder Polypropylen, die nicht klebfähig sind und deshalb an der Vorratsbehälterinnenwand in Verbindung mit dem auszutragenden Medium nicht anhaften.Preferred foam materials are polyethylene or polypropylene, that are not adhesive and therefore on the inside of the storage container Do not adhere to the medium to be discharged.

Als Austragvorrichtung bevorzugt ist eine Pumpenvorrichtung, wobei eine einfache Kolbenpumpe oder Verdrängerpumpe einsetzbar ist, die den Spender funktionssicher und wartungsarm macht.A pump device is preferred as the discharge device, one simple piston pump or positive displacement pump can be used which is the dispenser reliable and low maintenance.

Der Vorratsbehälter kann aus einem starren oder flexiblen Material besteht, wobei die Verwendung von flexiblem Material die Ausbildung festgelegter als auch variabler Krümmungsbereiche erlaubt, entlang derer der Kolben gleitfähig ist.The storage container can consist of a rigid or flexible material, being the use of flexible material the training set as well as variable areas of curvature along which the Piston is slidable.

Der Spender ist für das Austragen von pastösen, viskosen oder flüssigen Substanzen geeignet und ist in Handhabungsgeräte einbaubar. Der Vorratsbehälter kann dazu beispielsweise als Zahnbürstengriff ausgebildet oder in diesen einsetzbar sein, und die Austragvorrichtung einen am Zahnbürstenkopf endenden Zuführkanal speisen.The dispenser is for the discharge of pasty, viscous or liquid Suitable substances and can be installed in handling devices. The reservoir can for example be designed as a toothbrush handle or can be used in this, and the discharge device one on the toothbrush head feed the ending feed channel.

Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further embodiments of the invention are the following description and the subclaims.

Figur 1 zeigt einen Spender 1 zum Austragen eines fließfähigen Mediums, insbesondere einer pastösen, viskosen oder flüssigen Substanz, mit einem zylinderförmigen Vorratsbehälter 2, der eine Menge an fließfähigem Medium aufnimmt. Der zylinderförmige Vorratsbehälter 2 kann aus einem starren oder flexiblen Material, beispielsweise Glas oder Kunststoff, bestehen und weist vorzugsweise einen runden oder elliptischen Querschnitt auf. Der Vorratsbehälter 2 kann als langgestreckter Hohlkörper mit im wesentlichen gleichbleibenden Innenquerschnitt beliebige Querschnittsformen besitzen.FIG. 1 shows a dispenser 1 for discharging a flowable medium, in particular a pasty, viscous or liquid substance, with a cylindrical storage container 2, which has a lot of flowable Medium. The cylindrical storage container 2 can consist of one rigid or flexible material, for example glass or plastic, exist and preferably has a round or elliptical cross section on. The reservoir 2 can be an elongated hollow body with essentially constant internal cross-section any cross-sectional shape have.

Kopfseitig ist an dem Vorratsbehälter 2 eine manuell betätigbare, saugende Austragvorrichtung 3 befestigt, die vorzugsweise als Kolben- oder Verdrängerpumpe ausgebildet ist.At the top of the reservoir 2 is a manually operable, suction Discharge device 3 attached, preferably as a piston or Displacement pump is formed.

Bei dem in Fig. 1 dargestellten Spender, ist als Austragvorrichtung 3 eine Kolbenpumpe vorgesehen, die durch Niederdrücken eines vorstehenden Kolbenstößels 4 fließfähiges Medium aus dem Vorratsbehälter 2 über einen Saugeinlaß 5 ansaugt und über eine Saugauslaß 6 ausgibt. Der Saugauslaß 6 ist vorzugsweise an dem Kolbenstößel 4 vorgesehen.In the dispenser shown in FIG. 1, the discharge device is 3 a piston pump is provided by depressing a protruding one Piston tappet 4 flowable medium from the reservoir 2 via a Suction inlet 5 sucks and outputs via a suction outlet 6. The suction outlet 6 is preferably provided on the piston tappet 4.

Der Vorratsbehälter 2 enthält weiterhin einen in Längsrichtung beweglichen Kolben 7, der umfangsseitig an einer Innenwand 8 des Vorratsbehälters 2 anliegt und bodenseitig an eine austragbare Menge an fließfähigem Medium in dem Vorratsbehälter 2 anschließt. Der Kolben 7 ist ein lose eingesetzter Abschlußboden für das in dem Vorratsbehälter 2 enthaltene fließfähige Medium. Ein solcher Kolben 7 ist ein Folgekolben, der aufgrund der Saugwirkung der Austragvorrichtung 3 und dem entstehenden Vakuum nachgezogen wird.The reservoir 2 further contains a movable in the longitudinal direction Piston 7, the circumferential side on an inner wall 8 of the storage container 2 is applied and on the bottom side to a removable amount of flowable Medium in the reservoir 2 connects. The piston 7 is a loose used bottom for the contained in the reservoir 2 flowable medium. Such a piston 7 is a follower piston due to the suction effect of the discharge device 3 and the resulting vacuum is tightened.

Der Kolben 7 wird gebildet von einem Zylinderabschnitt aus einem umfänglich geschlossenporigen Weich-Schaumstoff mit einer geringen oder keiner Klebfähigkeit. Dabei ist der Kolben 7 mit einer gegenüber dem Innenquerschnitt des Vorratsbehälters 2 geringfügig übermaßigen Umfangsfläche versehen, so daß der Kolben 7 entlang der Vorratsbehälterinnenwand 8 gleitfähig ist. Da der Kolben 7 mit einem gewissen übermaß umfangsseitig an der Innenwand 8 anliegt, besitzt dieser einen Umriß, der sich an den Querschnitt des Vorratsbehälters 2 anpaßt und sich bei geringen Innenquerschnittsveränderungen in Krümmungsbereichen des Vorratsbehälters 2 aufgrund der elastischen Verformbarkeit eines Weich-Schaumstoffs passend schließend verändert.The piston 7 is formed by a cylinder section from a circumference closed pore soft foam with little or none Adhesiveness. The piston 7 is one with respect to the inner cross section of the storage container 2 slightly oversize peripheral surface provided so that the piston 7 along the inner wall 8 is slippery. Since the piston 7 with a certain excess circumference bears on the inner wall 8, this has an outline that is related to the Adapts cross-section of the reservoir 2 and changes with small changes in the cross-section in areas of curvature of the storage container 2 due to the elastic deformability of a soft foam finally changed.

Für den Vorratsbehälter 2 können somit auch beliebige Querschnittsformen gewählt werden, wenn eine grobe Formanpassung des Kolbens 7 vorgenommen wird, die das Anliegen der Umfangsfläche des Kolbens 7 unter Vorspannung sicherstellt. Feinanpassungen sind wegen der elastischen Struktur des Materials nicht erforderlich. Der Kolben 7 vollzieht diese in Selbstanpassung.Any cross-sectional shapes can thus also be used for the storage container 2 can be selected if a rough shape adjustment of the piston 7 is made is the application of the circumferential surface of the piston 7 under tension ensures. Fine adjustments are due to the elastic structure of the Material not required. The piston 7 performs this in self-adaptation.

Vorzugsweise besteht der Kolben 7 aus einem überwiegend geschlossenporigen Weich-Schaumstoff, und zwar aus einem feinporigen, weichelastischen Schaumstoff, der elastisch reversibel verformbar ist. Die Rohdichte des Schaumstoffs liegt vorzugsweise im Bereich zwischen 30 bis 70 kg/m3 fürein Polymer Polyethylen. Das Polyethylen ist ferner vorzugsweise extrusionsvernetzt geschäumt. Die Umfangsfläche des Kolbens 7 ist ferner vorzugsweise schrumpelig ausgebildet, was über die Porigkeit des Weich-Schaumstoffs einstellbar ist. Eine solche schrumpelige Umfangsfläche erlaubt eine Labyrinthabdichtung zwischen dem Kolben 7 und der Innenwand 8 des Vorratsbehälters 2, so daß das in dem Vorratsbehälter 2 enthaltene fließfähige Medium in einem durch den Kolben 7 verschlossenen Innenraum 9 des Vorratsbehälters 2 liegt. Dabei erlaubt die so gebildete Labyrinthabdichtung, daß bei einem Einsetzen des Kolbens 7 in den Vorratsbehälter 2 und Verschieben desselben in einen schlüsssigen Anschluß mit dem in dem Vorratsbehälter 2 enthaltenen Medium vorhandene Luft zunächst noch entweichen kann. Gelangt jeoche eine geringe Teilmenge des fließfähigen Mediums in die schrumpelige Umfangsfläche, füllen sich deren Rillen, so daß die Labyrinthabdichtung wirksam wird.The piston 7 preferably consists of a predominantly closed-pore soft foam, namely of a fine-pore, soft-elastic foam which is elastically reversibly deformable. The bulk density of the foam is preferably in the range between 30 to 70 kg / m 3 for a polymer polyethylene. The polyethylene is also preferably extrusion crosslinked. The circumferential surface of the piston 7 is also preferably made to be shriveled, which can be adjusted via the porosity of the soft foam. Such a shriveled peripheral surface allows a labyrinth seal between the piston 7 and the inner wall 8 of the storage container 2, so that the flowable medium contained in the storage container 2 lies in an interior 9 of the storage container 2 which is closed by the piston 7. The labyrinth seal thus formed allows that when the piston 7 is inserted into the storage container 2 and moved into a coherent connection with the medium contained in the storage container 2, air can initially still escape. However, if a small portion of the flowable medium gets into the shriveled peripheral surface, its grooves fill, so that the labyrinth seal becomes effective.

Hergestellt wird der Kolben 7 vorzugsweise durch Ablängen von Zylinderabschnitten von einem extrudierten Weich-Schaumstoffstrang. Dieses Ablängen erfolgt vorzugsweise durch einen Thermoschnitt, damit die Ablängseiten eine geschlossenporige Oberfläche aufweisen, insbesondere an der dem fließfähigen Material zugewandten Seite 14 des Kolbens 7. Alternativ kann der Kolben 7 auch spritzgegossen werden und damit auch in balligen Formen hergestellt werden.The piston 7 is preferably produced by cutting cylinder sections to length from an extruded soft foam strand. This cutting to length is preferably done by a thermal cut, so that the long sides have a closed-pore surface, especially on the side 14 of the piston facing the flowable material 7. Alternatively the piston 7 can also be injection molded and thus also in crowned Molds are made.

Als Weich-Schaumstoffmaterial bevorzugt ist Polyethylen oder Polypropylen, da dies Kunststoffmaterialien sind, die keine oder allenfalls nur eine geringe Klebfähigkeit aufweisen. Ferner können diese Materialien mit geschlossenporiger Oberfläche extrudiert oder spritzgegossen werden.Preferred soft foam material is polyethylene or polypropylene, since these are plastic materials that have no or at most only have low adhesiveness. Furthermore, these materials extruded or injection molded with a closed-pore surface.

Befindet sich ein fließfähiges Medium in dem Innenraum 9 des Vorratsbehälters 2, der kopfseitig von der Austragvorrichtung 3 und bodenseitig von dem Kolben 7 begrenzt wird, so wird bei einem Austrag des fließfähigen Mediums und der dadurch auftretenden Saugwirkung der Kolben 7, bedingt durch die Materialwahl für den Kolben 7 und dessen Anpassung an den Vorratsbehälter 2, nachgezogen.There is a flowable medium in the interior 9 of the storage container 2, the top of the discharge device 3 and the bottom is limited by the piston 7, so when the flowable is discharged Medium and the resulting suction effect of the piston 7, due through the choice of material for the piston 7 and its adjustment the reservoir 2, retightened.

Der mit fließfähigem Medium gefüllte Innenraum 9 verkleinert sich bei einer Ausgabe von fließfähigem Material, wobei der Kolben 7 schlüssig folgt, und zwar solange bis der Kolben 7 an die Austragvorrichtung 3 herangerückt ist (vgl. Fig. 2 Stellung (C) des Kolbens 7). Ein leerer Vorratsbehälter 2 kann durch Herausnehmen des Kolbens 7, Nachfüllen von fließfähigem Medium und erneutem bodenseitigen Einsetzen des Kolbens 7 neu gefüllt werden.The interior 9 filled with flowable medium is reduced in size an output of flowable material, the piston 7 being coherent follows, until the piston 7 on the discharge device 3rd has advanced (see FIG. 2 position (C) of the piston 7). An empty one Storage container 2 can by removing the piston 7, refilling flowable medium and renewed insertion of the piston on the bottom 7 to be refilled.

Der vorstehend beschriebene Spender 1 kann in Handhabungsgeräte eingebaut werden, insbesondere in Spenderzahnbürsten. Wie in FIg. 1 dargestellt, kann der Spender 1 unmittelbar einen Zahnbürstengriff bilden, wobei ein Zahnbürstenkopfaufsatz 10 aufgesetzt ist.

Ein durch den Zahnbürstenkopfhals 11 geführter und an der Zahnbürstenkopfplatte 12 endender Zuführungskanal 15 wird über denSaugauslaß 6 der Austragvorrichtung 3 gespeist. Der Zahnbürstenkopfaufsatz 10 kann in bekannter Weise an dem Spender 1 befestigt sein, gegebenenfalls auf dem Kolbenstößel 4 sitzen, so daß durch ein Aufeinanderzubewegen von Zahnbürstenkopfaufsatz 10 und Spender 1 die Austragvorrichtung 3 betätigt wird. Andere bekannte Betätigungseinrichtungen und Verbindungsarten von Spender 1 und Aufsatz 10 sind verwendbar.The dispenser 1 described above can be installed in handling devices especially in donor toothbrushes. As in FIg. 1 shown the dispenser 1 can immediately form a toothbrush handle, wherein a toothbrush head attachment 10 is attached. This toothbrush head attachment 10 includes a toothbrush head neck 11 and a toothbrush head plate 12 with bristles 13. A through the toothbrush head neck 11 and feed channel 15 terminating at the toothbrush head plate 12 is fed via the suction outlet 6 of the discharge device 3. The toothbrush head attachment 10 can be attached to the dispenser 1 in a known manner be, if necessary, sit on the piston rod 4, so that by a Moving toothbrush head attachment 10 and dispenser 1 together Discharge device 3 is operated. Other known actuators and connection types of dispenser 1 and attachment 10 can be used.
