Description

Die vorliegende Erfindung betrifft einen Spender für pastöse Produkte nach dem Oberbegriff des Anspruchs 1.The present invention relates to a dispenser for pasty products according to the preamble of claim 1.

Derartige Spender sind als ambulante Versorgungseinheiten in einer Vielzahl von Anwendungsbereichen bekannt, z.B. für die Ausspendung von Cremes zur Gesundheits- und Körperpflege im Bereich der Haushaltchemikalien und Schuhpflegemittel, aber auch zur Bereitstellung pastöser Lebensmittel, Genuß- und Gewürzmittel.Such donors are known as outpatient care units in a variety of applications, e.g. for the distribution of creams for health and personal care in the field of household chemicals and shoe care products, but also for the provision of pasty foods, luxury foods and spices.

Die Vielzahl spezifischer Anwendungen und Gestaltungserfordernisse hat auch in der Ausgestaltung von Kolbenspendern für die Bereitstellung der sehr unterschiedlichen pastösen Massen zu einer Gestaltungsvielfalt geführt. Häufig sind die unmittelbaren Ausförder- und Handhabungsmechanismen der Spender jedoch verhältnismäßig kompliziert in der Herstellung und/oder Handhabung, führen zu einem Verschmieren bei der Ausspendung und erweisen sich als nicht in wünschenswertem Maße zuverlässig für die exakt portionierte und saubere Ausspendung des jeweiligen Produkts über einen längeren Zeitraum.The large number of specific applications and design requirements has also led to a variety of designs in the design of piston dispensers for the provision of the very different pasty masses. Often, however, the direct delivery and handling mechanisms of the dispensers are relatively complicated to manufacture and / or handle, lead to smearing when dispensing and prove to be undesirably reliable for the exact portioned and clean dispensing of the respective product over a longer period Period.

Aus der FR-A-2 594 419 ist ein Spender für pastöse Produkte bekannt mit einem das Produkt in einem Behälterinnenraum enthaltenden zylindrischen Behälter, der bodenseitig einen unter dem Druck der Außenatmosphäre an einer Behälterinnenwand gleitverschieblichen Nachlaufkolben aufweist sowie an seinem oberen Ende ein Kopfstück besitzt, das eine handbetätigte Fördereinrichtung mit einer Pumpkammer und einem Förderkolben sowie einen Ausgabekanal für das Produkt aufweist. Gemäß dem Spender des Standes der Technik sind die Pumpkammer und eine Streifenkammer einer Ausgabeeinheit ventillos radial nebeneinanderliegend angeordnet und frei kommunizierend mit dem Behälterraum verbunden. Weiterhin ist eine Ausgabeeinheit vorgesehen, die einen die Streifen begrenzenden Streifenkammerzylinder, zumindest einen, den Ausgabekanal begrenzenden Mundstückkörper sowie ein einer Ausgabeöffnung des Mundstückkörpers zugeordnetes Visier aufweist.From FR-A-2 594 419 a dispenser for pasty products is known with a cylindrical container containing the product in a container interior, which has on the bottom side a follower piston which can slide on the inside wall of the container under the pressure of the outside atmosphere and has a head piece at its upper end, which has a manually operated conveyor with a pumping chamber and a delivery piston and an outlet channel for the product. According to the prior art dispenser, the pumping chamber and a strip chamber of an output unit are arranged radially next to one another without a valve and freely communicating with the container space connected. Furthermore, an output unit is provided which has a strip chamber cylinder which delimits the strips, at least one mouthpiece body which delimits the output channel and a visor which is assigned to an output opening of the mouthpiece body.

Der Stand der Technik gemäß FR-A-2 594 419 weist zur Förderung des Produkts eine als Membranpumpe ausgebildete Pumpe auf.The prior art according to FR-A-2 594 419 has a pump designed as a diaphragm pump for conveying the product.

Aus der GB-A-2 172 664 ist eine Spendervorrichtung bekannt, die eine Kolbenpumpe aufweist. Der Spender dient beispielsweise zur Ausgabe von Zahnpasta.From GB-A-2 172 664 a dispenser device is known which has a piston pump. The dispenser is used, for example, to dispense toothpaste.

Aufgabe der vorliegenden Erfindung ist es, einen Spender der eingangs genannten Art derart zu verbesseren, daß er einen besonders einfachen und sicheren Aufbau aufweist, wodurch ein entsprechend zuverlässig und exakt portioniertes sauberes Ausgeben des jeweiligen Produktes über einen längeren Zeitraum erreicht wird.The object of the present invention is to improve a dispenser of the type mentioned at the outset in such a way that it has a particularly simple and safe structure, as a result of which a correspondingly reliable and precisely portioned, clean dispensing of the respective product is achieved over a longer period of time.

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

Dadurch wird eine besonders einfache Öffnungsbetätigung des Visiers erreicht, wobei bei einer Druckbetätigung der Betätigungshülse nach unten erreicht wird, daß auf Anfangsabschnitte der Betätigungsfinger eine abwärts weisende Kraft übertragen wird mit der Folge, daß hierdurch das Oberteil des Visiers eine Schwenkbewegung erfährt um ein im Bereich der Abwinklung des Betätigungsfingers sich bildendes Gelenk des Visiers.This results in a particularly simple opening operation of the visor, whereby when the actuating sleeve is actuated downwards, a downward force is transmitted to the starting sections of the actuating finger, with the result that the upper part of the visor experiences a pivoting movement in the region of the Angle of the actuating finger forming hinge of the visor.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles und zugehöriger Zeichnungen näher erläutert. In diesen zeigen:

Nachfolgend wird zunächst auf Fig. 1 bezug genommen, die einen Spender 1 für pastöse Produkte nach der vorliegenden Erfindung im Längsschnitt zeigt. Ein auszuspendendes, hier nicht mit dargestelltes Produkt, z.B. Zahncreme, befindet sich innerhalb eines Behälters 2, dessen Behälterinnenraum 3 an seiner Oberseite ungehindert in eine Pumpkammer 5 sowie eine Streifenkammer 6 übergeht. Die Pumpkammer 5 und die Streifenkammer 6 werden jeweils durch einen Pumpzylinder 7 bzw. einen Streifenkammerzylinder 8 begrenzt, die radial nebeneinanderliegend angeordnet sind und einen gemeinsamen Wandbereich 9 aufweisen. Pumpzylinder 7 und Streifenkammenzylinder 8 bilden mit dem Behälter 2 ein integrales Kunststoffteil, das vorzugsweise als Spritzgußteil hergestellt ist. Mit Ausnahme einer Rückstellfeder 14 bestehen auch die weiteren, nachstehend noch im einzelnen erläuterten Teile des Spenders 1 aus spritzgußfähigem Kunststoff, vorzugsweise aus Polyethylen oder Polypropylen, so daß der Spender 1 einerseits sehr leicht ist und andererseits eine Beeinträchtigung der auszuspendenden pastösen Masse durch das Material des Spenders und umgekehrt Beeinträchtigungen der mit der auszuspendenden Masse in Kontakt tretenden Teile des Spenders 1 durch diese Masse unterbleiben. Zur kontinuierlichen Aufwärtsförderung der pastösen Masse innerhalb des Behälters 2 nach oben in die Pumpkammer 5 ist ein längs der inneren Behälterwandung unter dem Einfluß des Atmosphärendruckes gleitverschieblicher und gegen den Pumpdruck durch eine Spreizfeder abgestützter Nachlaufkolben 4 vorgesehen, durch den die pastöse Masse im Behälter 2 ständig unter dem Druck der Umgebungsatmosphäre gehalten ist. Auf diese Weise wird eine sehr einfache Nachführung des pastösen Produktes innerhalb des Behälters 2 nach oben in den Bereich eines Förderkolbens 10 gewährleistet und bei Ausgabe des pastösen Produktes aus dem Spender 1 ein Unterdruck innerhalb des Behälters 2 vermieden. In den nach unten zum Behälterinnenraum ebenfalls offenen Streifenkammerzylinder 8 ist von oben in einen Halterungshalsabschnitt desselben dornartig ein erster, rohrförmiger Mundstückkörper 17 eingesetzt, der im wesentlichen bis in den Bereich des Überganges von der Streifenkammer 6 zum Behälterinnenraum 3 reicht und der der Streifenkammer 6 eine Ringstruktur verleiht. An der Unterseite dieses ersten Mundstückkörpers 17 ist eine Öffnung 17′ vorgesehen, die zugleich den Beginn eines Ausgabekanales 29 bildet. Am Umfang des ersten Mundstückkörpers 17 sind im Bereich des oberen Endes der Streifenkammer 6 Öffnungen oder Schlitze vorgesehen, die nachfolgend als Farbspenderöffnungen 18 bezeichnet werden. In der Streifenkammer 6 ist im vorliegenden Ausführungsbeispiel ein pastöser Farbstoff (hier nicht gezeigt) aufgenommen, der sich innerhalb der Streifenkammer, den Ringraum ausfüllend , nach unten bis kurz vor das untere Ende des ersten Mundstückkörpers 17 erstreckt und dort auf der im übrigen den Behälterinnenraum 3 sowie die Pumpkammer 5 ausfüllenden, auszuspendenden pastösen Produktmasse, z. B. Zahncreme aufliegt.In the following, reference is first made to FIG. 1, which shows a dispenser 1 for pasty products according to the present invention in longitudinal section. A product to be dispensed, not shown here, for example toothpaste, is located within a container 2, the container interior 3 of which merges freely into a pump chamber 5 and a strip chamber 6 on its upper side. The pump chamber 5 and the strip chamber 6 are each delimited by a pump cylinder 7 and a strip chamber cylinder 8, respectively, which are arranged radially next to one another and have a common wall area 9. Pump cylinder 7 and strip comb cylinder 8 form with the container 2 an integral plastic part, which is preferably made as an injection molded part. With the exception of a return spring 14, the other parts of the dispenser 1, which will be explained in more detail below, also consist of injection-molded plastic, preferably of polyethylene or polypropylene, so that the dispenser 1 is very light on the one hand and on the other hand the pasty mass to be dispensed is impaired by the material of the dispenser Donors and vice versa no impairment of the parts of the dispenser 1 which come into contact with the mass to be dispensed due to this mass. For continuous upward promotion the pasty mass inside the container 2 upwards into the pumping chamber 5 is a follower piston 4 which is slidable along the inner wall of the container under the influence of atmospheric pressure and is supported against the pump pressure by an expansion spring, through which the pasty mass in the container 2 is constantly under the pressure of the Ambient atmosphere is kept. In this way, a very simple tracking of the pasty product inside the container 2 is ensured upwards into the area of a delivery piston 10 and a negative pressure within the container 2 is avoided when the pasty product is dispensed from the dispenser 1. In the strip chamber cylinder 8, which is also open downwards to the container interior, a first, tubular mouthpiece body 17 is inserted from above into a mounting neck portion of the same, which extends essentially into the region of the transition from the strip chamber 6 to the container interior 3 and that of the strip chamber 6 has an annular structure gives. At the bottom of this first mouthpiece body 17, an opening 17 'is provided, which also forms the beginning of an output channel 29. At the periphery of the first mouthpiece body 17 6 openings or slots are provided in the region of the upper end of the strip chamber, which are hereinafter referred to as paint dispenser openings 18. In the strip chamber 6, a pasty dye (not shown here) is accommodated in the present exemplary embodiment, which extends within the strip chamber, filling the annular space, downwards to just before the lower end of the first mouthpiece body 17 and there on the rest of the container interior 3 and the pump chamber 5 filling, dispensing pasty product mass, for. B. toothpaste.

Der Pumpzylinder 7 und der Streifenkammerzylinder 8 weisen gegenüberliegend an ihren Außenumfangsflächen 7′ bzw. 8′ Rastnasen 27a bzw. 27b auf, die der unverlierbaren Aufnahme eines zweiten, den Ausgabekanal 29 fortsetzenden zweiten Mundstückkörper 15 dienen. Dieser ist, ebenso wie der erste Mundstückkörper 17 ebenfalls ein Kunststoff-Spritzteil, das verrastend auf den Pumpzylinder 7 und den Streifenkammerzylinder 8 im Bereich eines Absatzes 26, die zum Behälter 2 hin ausgebildet ist, aufgesetzt wird. Der zweite Mundstückkörper 15 bildet somit das Ende des Ausgabekanales 29 mit der Ausgabeöffnung 16. Deren Freigabe bzw. Verschluß wird durch ein nachstehend noch im einzelnen erläutertes Visier 20 aus Kunststoff bewirkt, das mit einem Fußabschnitt 22 in einer Tasche 19 des zweiten Mundstückkörpers 15 gehalten ist.The pump cylinder 7 and the strip chamber cylinder 8 have opposite on their outer peripheral surfaces 7 'and 8' locking lugs 27a and 27b, which serve the captive reception of a second, the discharge channel 29 continuing second mouthpiece body 15. Like the first mouthpiece body 17, this is also a plastic injection-molded part, which is latched onto the pump cylinder 7 and the strip chamber cylinder 8 in the region of a shoulder 26, which is formed toward the container 2. The second mouthpiece body 15 thus forms the end of the dispensing channel 29 with the dispensing opening 16. Its release or closure is brought about by a visor 20, which will be explained in detail below and is held with a foot section 22 in a pocket 19 of the second mouthpiece body 15 .

Der Streifenkammerzylinder 8, die Mundstückkörper 15 und 17 mit dem Ausgabekanal 29 und der Ausgabeöffnung 16 sowie das dieser zugeordnete Visier 20 bilden zusammen eine Ausgabeeinheit A im Kopfstück des Spenders 1.The strip chamber cylinder 8, the mouthpiece bodies 15 and 17 with the dispensing channel 29 and the dispensing opening 16 and the visor 20 associated therewith together form an dispensing unit A in the headpiece of the dispenser 1.

Zur Spenderbetätigung ist im übrigen Bereich des Kopfstückes des Spenders 1 eine Kolben-Fördereinrichtung vorgesehen, die aus der vom Pumzylinder 7 begrenzten Pumpkammer 5 mit dem in dieser gleitverschieblichen Förderkolben 10, einer oberen Betätigungshülse 13, einem die Betätigungshülse 13 mit den Förderkolben verbindenden Betätigungsrohrkörper 12 sowie einer zwischen einer äußeren Oberseite des Pumpzylinders 7 und einer inneren Bodenfläche der Betätigungshülse 13 vorgespannten Rückstell-Schraubenfeder 14 besteht. Ein entsprechend der Außenformgebung der Betätigungshülse 13 gestalteter Bereich des zweiten Mundstückkörpers 15 dient zugleich als Führung für die Betätigungshülse 13 (vgl. auch Fig. 2).For actuating the dispenser, a piston delivery device is provided in the remaining area of the headpiece of dispenser 1, which from the pump chamber 5 delimited by the pump cylinder 7 with the delivery piston 10 slidably displaceable therein, an upper actuation sleeve 13, an actuation tube body 12 connecting the actuation sleeve 13 with the delivery piston a return coil spring 14 biased between an outer top of the pump cylinder 7 and an inner bottom surface of the actuating sleeve 13. A region of the second mouthpiece body designed in accordance with the external shape of the actuating sleeve 13 15 also serves as a guide for the actuating sleeve 13 (see also FIG. 2).

Das den Verschluß bzw. die Freigabe der Ausgabeöffnung 16 herbeiführende Visier,mit dem wie in Fig. 1 gezeigt die Betätigungshülse 13 über nasenartige Vorsprünge 25 im Eingriff ist, wird nachfolgend auch unter Bezugnahme auf Fig. 3 näher erläutert.The visor causing the closure or release of the dispensing opening 16, with which the actuating sleeve 13 engages via nose-like projections 25 as shown in FIG. 1, is also explained in more detail below with reference to FIG. 3.

Das Visier 20 aus einem Kunststoff-Bandstück hat die Gestalt eines abgewinkelten Bandkörpers mit einem oberen, in Schließlage die Ausgabeöffnung 16 abdeckenden, im wesentlichen kreisförmigen Verschlußabschnitt 21 sowie einem sich in Verlängerung eines Zwischenabschnittes des Visiers 20 erstreckenden mittleren Fußabschnitt 22, der in der Tasche 19 des zweiten Mundstückkörpers 15 ortsfest aufgenommen ist. Beiderseits des mittleren Fußabschnitts 22 des Visiers 20 sind streifenförige Betätigungsfinger 23 schräg abgewinkelt, wobei die Anordnung im Verhältnis zu der benachbarten Betätigugnshülse 13 so getroffen ist, daß die Betätigungsfinger 23 unter die Betätigungshülse 13 greifen. Durch die Aufnahme des Fußabschnittes 22 des Visiers 20 in der Tasche 19 des zweiten Mundstückes 15 ist das Visier 20 einseitig eingespannt und kann bezüglich seines Bereiches oberhalb der Abwinklung der Betätigungsfinger 23 durch Druck auf selbige schwenkbetätigt werden. Zu diesem Zweck ist die Betätigungshülse 13 mit nasenförmigen Vorsprüngen 25 (siehe Fig. 2 ) versehen, mit denen die Betätigungshülse 13 an den Betätigungsfingern 23 im Bereich ihrer Abwinklung vom übrigen Teil des Visiers 20 angreift.The visor 20 made of a plastic band piece has the shape of an angled band body with an upper, essentially circular closure section 21 covering the dispensing opening 16 in the closed position and a middle foot section 22 extending in the extension of an intermediate section of the visor 20, which is in the pocket 19 of the second mouthpiece body 15 is received in a stationary manner. On both sides of the middle foot section 22 of the visor 20, stripe-shaped actuating fingers 23 are angled obliquely, the arrangement in relation to the adjacent actuating sleeve 13 being such that the actuating fingers 23 engage under the actuating sleeve 13. By accommodating the foot section 22 of the visor 20 in the pocket 19 of the second mouthpiece 15, the visor 20 is clamped on one side and can be pivotally actuated with respect to its area above the angled portion of the actuating fingers 23 by pressing it. For this purpose, the actuating sleeve 13 is provided with nose-shaped projections 25 (see FIG. 2) with which the actuating sleeve 13 engages on the actuating fingers 23 in the region of their angling from the remaining part of the visor 20.

Der Spender 1 kann im Bereich seines Kopfstückes nach außen durch eine Verschlußkappe 28 abgeschlossen werden, die über Rastnasen 27b an der zweiten Betätigungshülse 13 elastisch verrastet werden kann, derart, daß die Verschlußkappe 28 einen glatten, fluchtenden Abschluß zu dem Behälter 2 im Bereich des Absatzes 26 bildet, so daß der gesamte Spender im verschlossenen Zustand eine völlig glatte Außenkontur aufweist.The dispenser 1 can be in the area of its head piece be closed off to the outside by a closure cap 28, which can be elastically latched to the second actuating sleeve 13 via latching lugs 27b, in such a way that the closure cap 28 forms a smooth, flush closure to the container 2 in the region of the shoulder 26, so that the entire dispenser has a completely smooth outer contour when closed.

Wie insbesondere aus Fig. 2 hervorgeht, ist in diesem Ausführungsbeispiel der Spender 1 mit einem Behälter ovalen oder elliptischen Querschnittes versehen, so daß eine ergonomisch günstige Gestaltung und grifftechnisch einfache Handhabung des Spenders 1 erfolgen kann. Eine solche Gestaltung wird durch die in radialer Richtung hintereinanderliegende Ausbildung der Ausgabeeinheit A, insbesondere des Streifenkammerzylinders 8 und des Pumpzylinders 7 unterstützt. Die Handhabung wird ferner dadurch erleichtert, daß die Betätigungshülse 13 auf einen niedrigeren Niveau als die Ausgabeöffnung 16 angeordnet ist.As can be seen in particular from FIG. 2, in this embodiment the dispenser 1 is provided with a container of oval or elliptical cross-section, so that the dispenser 1 can be designed ergonomically and easy to handle. Such a design is supported by the design of the dispensing unit A, in particular the strip chamber cylinder 8 and the pump cylinder 7, which are arranged one behind the other in the radial direction. Handling is further facilitated in that the actuating sleeve 13 is arranged at a lower level than the dispensing opening 16.

Bezugnehmend auf Fig. 2 zeigt diese schematisch den Spender 1 bei abgenommener Verschlußkappe 28 von oben, wobei neben der elliptischen Grundform des Spenders 1 ersichtlich ist, daß auch das zweite Mundstück 15 im Bereich des Ausgabekanales 29 bzw. der Auslaßöffnung 16 eine ovale Gestalt besitzt und dies auch auf den Streifenkammerzylinder 8 zutrifft. Selbstverständlich können der Streifenkammerzylinder sowie der zweite Mundstückkörper 15 im Bereich des Ausgabekanales 29 auch einen kreisförmigen Querschnitt aufweisen. Dies gilt gleichermaßen auch für den Behälter 2 selbst, der, wenn dies gewünscht wird,auch die Form eines geraden Kreiszylinders mit entsprechenden Folgen für die Querschnittsgestaltung der Verschlußkappe 28 sowie den zweiten Mundstückkörper 15 haben kann.2, this shows schematically the dispenser 1 with the closure cap 28 removed from above, and in addition to the elliptical basic shape of the dispenser 1 it can be seen that the second mouthpiece 15 also has an oval shape in the region of the dispensing channel 29 or the outlet opening 16 and this also applies to the strip chamber cylinder 8. Of course, the strip chamber cylinder and the second mouthpiece body 15 can also have a circular cross section in the region of the discharge channel 29. This also applies equally to the container 2 itself, which, if desired, also has the shape of a straight one Circular cylinder with corresponding consequences for the cross-sectional design of the closure cap 28 and the second mouthpiece body 15 can have.

Fig. 2 verdeutlicht auch die Vorsprünge 25 der Betätigungshülse 13 zum Angriff an den Betätigungsfingern 23 des Visiers 20, wobei hierfür selbstverständlich auch andere Formgebungen gewählt oder eine den Angriff an den Betätigungsfingern 23 sichernde, vorsprungslose Ausführung der Betätigungshülse 13 gewählt werden kann.Fig. 2 also illustrates the projections 25 of the actuating sleeve 13 for attacking the actuating fingers 23 of the visor 20, wherein of course other shapes can be selected for this, or a non-protruding design of the actuating sleeve 13 securing the attack on the actuating fingers 23 can be selected.

Der Förderkolben 10 besitzt zur Aufnahme an dem Betätigungsrohrkörper 12 in einem Schnappverbindungssitz einen Hutabschnitt 10′ und ist als Stufenkolben mit gegenüber den paarig vorgesehenen Ringdichtungslippen vorauslaufender Stirnfläche ausgebildet. Dies führt zu einer Druckentlastung und verbesserten Abdichtung im Dichtungsbereich des Förderkolbens 10.The feed plunger 10 has a hat section 10 'for receiving it on the actuating tube body 12 in a snap connection seat and is designed as a stepped plunger with an end face leading in relation to the pair of ring sealing lips. This leads to pressure relief and improved sealing in the sealing area of the delivery piston 10.

Die Herstellung und Montage des vorerläuterten Spenders 1, der als Kolbenspender und insbesondere als Streifenspender durch den ein z.B. mit ornamentalen Farbstreifen versehener Produktstrang in einer Zweikomponentenform bereitgestellt werden kann, ausgebildet ist, ist insbesondere durch den Wegfall sämtlicher Ventileinrichtungen und der seriellen Anordnung von Fördereinrichtung und Ausgabeeinheit A des Spenders 1 besonders einfach und unkompliziert. Nach Herstellung des Behälters 1 mit dem Pumpzylinder 7 und Streifenkammerzylinder 8 als integralem Kunststoff-Spritzgußteil ist es lediglich erforderlich, in einem Kragenbereich des Streifenkammerzylinders 8 den ersten Mundstückkörper 7 aus Kunsstoff im Preßsitz einzusetzen und den zweiten Mundstückkörper 15 mit dem Visier 20 verrastend auf den Umfangsabschnitten der Außenumfangsflächen 7′, 8′ von Pumpzylinder 7 und Streifenkammerzylinder 8 in einem Schnappsitz aufzudrücken. Der Förderkolben 10 ist das einzige von innen zu montierende Teil und wird in der Pumpkammer 5 aufgenommen sowie anschließend nach Aufsetzen der Rückstellfeder 14 durch Aufdrücken der Betätigungshülse 13 mit dem Betätigungsrohrkörper 12 in einem Schnappsitz mit letzterem verrastet. Der so in seinem Kopfstück bereits fertig montierte Spender 1 wird nunmehr in Kopfunterlage gefüllt, wobei beispielsweise in die ringförmige Streifenkammer 6 ein eine pastöse oder zähflüssige Konsistenz aufweisender Farbstoff eingefüllt wird, und zwar bis zu einer Füllhöhe, die sich bis knapp vor das Ende des ersten Mundstückkörpers 17, bzw, bis kurz vor die Öffnung 17′ erstreckt. Anschließend erfolgt die Füllung des Spenders 1 mit dem auszugebenden Hauptprodukt, z.B. mit Zahncreme, beginnend mit der Füllung der Pumpkammer 5. Im Bereich der Streifenkammer 8 liegt die Hauptproduktmasse während des Füllvorganges auf der Farbstoffmasse innerhalb der Streifenkammer 6 auf und befindet sich zumindest auch im Bereich der Öffnung 17′ des ersten Munsstückkörpers 17. Nach vollständiger Füllung des Behälters 2 wird der Nachlaufkolben 4 eingesetzt und der Spender 1 ist betriebsbereit. Die Verschlußkappe 28 ist bereits vorher aufgesetzt worden oder wird abschließend auf dem zweiten Mundstückkörper 15 aufgenommen.The manufacture and assembly of the previously explained dispenser 1, which is designed as a piston dispenser and in particular as a strip dispenser, by means of which a product strand, for example provided with ornamental colored strips, can be provided in a two-component form, is particularly due to the elimination of all valve devices and the serial arrangement of the conveying device and dispensing unit A des Dispenser 1 is particularly simple and straightforward. After the manufacture of the container 1 with the pump cylinder 7 and the strip chamber cylinder 8 as an integral plastic injection molded part, it is only necessary to press-fit the first mouthpiece body 7 made of plastic in a collar region of the strip chamber cylinder 8 and to lock the second mouthpiece body 15 with the visor 20 on the peripheral sections to press the outer peripheral surfaces 7 ', 8' of the pump cylinder 7 and the strip chamber cylinder 8 in a snap fit. The delivery piston 10 is the only part to be assembled from the inside and is received in the pump chamber 5 and then, after the return spring 14 has been put on, by pressing the actuating sleeve 13 with the actuating tube body 12 in a snap fit with the latter. The dispenser 1 already assembled in this manner in its head piece is now filled into a head support, with a dye having a pasty or viscous consistency being filled, for example, into the annular strip chamber 6, to a fill level that is just before the end of the first Mouthpiece body 17, or, until just before the opening 17 'extends. Subsequently, the dispenser 1 is filled with the main product to be dispensed, for example with toothpaste, starting with the filling of the pump chamber 5. In the area of the strip chamber 8, the main product mass lies on the dye mass within the strip chamber 6 during the filling process and is at least also in the area the opening 17 'of the first Munsstückkörpers 17. After the container 2 has been completely filled, the trailing piston 4 is inserted and the dispenser 1 is ready for operation. The closure cap 28 has already been put on beforehand or is finally received on the second mouthpiece body 15.

Nachstehend wird die Funktionsweise des Spenders 1 erläutert. Ausgehend von einem Zustand gemäß Fig. 1 und dem z.B. mit Zahncreme gefüllten Behälter 2 sowie gleichermaßen mit Zahncreme gefüllter Pumpkammer 5 und der z.B. mit Farbpaste gefüllten Streifenkammer 6, wobei die Farbpaste oberhalb der Öffnung 17′ auf der Zahncreme aufruht, wird nach Abnahme der Verschlußkappe 28 die Betätigungshülse 13 durch Fingerdruck entgegen der Kraft der Rückstellfeder 14 nach unten gedrückt. Dies hat zur Folge, daß die Vorsprünge 25 der Betätigungshülse 13 nach unten bewegt werden, mit der Folge einer Einwärtsschwenkbewegung der Bewegungsfinger 23, so daß sich infolge hinlänglicher Steifigkeit der Abwinklung der Betätigungsfinger 23 von dem Visier 20 bei 24 ein Gelenk ausbildet und im Zuge der Abwärtsbewegung der Betätigungshülse 13 das Visier20 in seinen Teil oberhalb des Gelenkes 24 mit dem Verschlußabschnitt 21 nach außen geschwenkt wird, wie dies in Fig. 1 in unterbrochenen Linien dargestellt ist. Sogleich führt der infolge der Abwärtsbewegung des Förderkolbens 10 auf die Zahncreme im Behälter 2 ausgeübte und durch die Spreizfeder des Nachlaufkolbens 4 abgestützte Druck dazu, daß die Zahncreme durch die Öffnung 17′ des ersten Mundstückkörpers 17 hindurch in den Ausgabekanal 29 in Ausförderrichtung zur Ausgabeöffnung 16 bewegt wird. Gegebenenfalls tritt auch eine leichte Druckerhöhung im Grenzgebiet zwischen Zahncreme und Farbpaste in der Streifenkammer 6 ein. Beim Vorbeifließen der Zahncreme an den Farbspenderöffnungen 18 am Umfang des ersten Mundstückkörpers 17 tritt infolge der durch die Zahncreme verursachten Unterdruck-Sogwirkung Farbmasse durch die Farbspenderöffnungen 18 hindurch auf den Umfang des Zahncremestranges im Ausgabekanal 29 hindurch, so daß entsprechend der Umfangsverteilung der Farbspenderöffnungen 18 der Zahncremestrang oberhalb dieser Farbspenderöffnungen 18 mit farbigen Längsstreifen infolge der in der Streifenkammer 6 befindlichen Farbpaste versehen ist. In Abhängigkeit vom Volumenverhältnis zwischen der Pumpkammer 5 und dem Ausgabekanal 29 kann es bei Erstbetätigung des Spenders 1 erforderlich sein, zunächst in einem Leerhub die auszuspendende Produktmasse bis in den Bereich der Ausgabeöffnung 16 zu führen, so daß vom Beginn des zweiten Spendehubes an beständig Produktmasse an der Ausgabeöffnung 16 zur Verfügung steht.The operation of the dispenser 1 is explained below. Starting from a state according to FIG. 1 and the container 2 filled with toothpaste, for example, as well as pump chamber 5 filled with toothpaste and the strip chamber 6 filled, for example, with color paste, the color paste resting above the opening 17 'on the toothpaste, after removal of the closure cap 28 the actuating sleeve 13 is pressed downward by finger pressure against the force of the return spring 14. This has the consequence that the projections 25 of the actuating sleeve 13 are moved downward, with the result of an inward pivoting movement of the movement fingers 23, so that due to the sufficient rigidity of the angling of the actuating fingers 23 from the visor 20 a joint is formed at 24 and in the course of the Downward movement of the actuating sleeve 13, the visor 20 is pivoted in its part above the joint 24 with the closure section 21 to the outside, as shown in broken lines in FIG. 1. Immediately the result of the downward movement of the delivery piston 10 on the toothpaste in the container 2 and supported by the spreading spring of the follower piston 4 causes the toothpaste to move through the opening 17 'of the first mouthpiece body 17 into the discharge channel 29 in the discharge direction to the discharge opening 16 becomes. There may also be a slight increase in pressure in the border area between toothpaste and color paste in the strip chamber 6. When the toothpaste flows past the color donor openings 18 on the circumference of the first mouthpiece body 17, due to the negative pressure suction effect caused by the toothpaste, color mass passes through the color donor openings 18 onto the circumference of the toothpaste strand in the discharge channel 29, so that the toothpaste strand corresponds to the circumferential distribution of the color donor openings 18 above this color dispenser openings 18 is provided with colored longitudinal strips as a result of the color paste located in the strip chamber 6. Depending on the volume ratio between the pumping chamber 5 and the dispensing channel 29, when the dispenser 1 is actuated for the first time, it may be necessary to first guide the product mass to be dispensed into the region of the dispensing opening 16 in an idle stroke, so that product mass is stable from the beginning of the second dispensing stroke the dispensing opening 16 is available.

Nach Ausspenden des mit Farbstreifen versehenen Zahncremestranges nach dem Maße des Hubes des Förderkolbens 10 kommt es bei Druckentlastung der Betätigungshülse 13 und der Aufwärtsbewegung des Förderkolbens 10 in der Pumpkammer 5 einerseits zu einem geringfügigen Rückzug von Zahncrememasse im Bereich der Ausgabeöffnung 16 und zu einem sauberen Ende des Spendevorganges sowie andererseits durch Nachlauf des Nachlaufkolbens 4 und Aufwärtsförderung der Zahncreme im Behälter 2 unter dem Einfluß des Atmosphärendruckes zu einem beständigen Druckausgleich innerhalb des Spenders 1 sowie gleichzeitig durch Entlastung der Betätigungsfinger 23 des Visiers 20 zu einer Rückkehr desselben in seine in Fig. 1 in Vollinien gezeigte Schließlage.After dispensing the toothpaste strand provided with colored stripes according to the dimension of the stroke of the delivery piston 10, pressure relief of the actuating sleeve 13 and the upward movement of the delivery piston 10 in the pump chamber 5 on the one hand result in a slight withdrawal of toothpaste composition in the region of the discharge opening 16 and a clean end of the Dispensing process and on the other hand by wake of the trailing piston 4 and upward conveyance of the toothpaste in the container 2 under the influence of atmospheric pressure to a constant pressure equalization within the dispenser 1 and at the same time by relieving the actuating fingers 23 of the visor 20 to return it to its in Fig. 1 in full lines shown closed position.

Auf diese Weise wird unter Vermeidung von Ventilen zwischen dem Behälterinnenraum 3 und der Pumpkammer 5 bzw. der Ausgabeeinheit A ein äußerst zuverlässig und sauber arbeitender Streifenspender realisiert, der zur Ausspendung verschiedenster pastöser Produkte geeignet ist und die Ausspendung eines Produktes in verschiedenen Farbmustern gestattet.In this way, avoiding valves between the container interior 3 and the pumping chamber 5 or the dispensing unit A, an extremely reliable and clean-working strip dispenser is realized, which is suitable for dispensing a wide variety of pasty products and allows the dispensing of a product in different color patterns.

Darüberhinaus ist es z.B. auch möglich, bei der Verwendung des Spenders 1 als Streifenspender zur Ausspendung pastöser Lebensmittel innerhalb der Streifenkammer eine Gewürzpaste vorzusehen, um das auszuspendende, innerhalb des Behälters 2 und der Pumpkammer 5 befindliche Lebensmittelhauptprodukt mit einer bestimmten Gewürzbeimengung verteilt am Umfang des ausgespendeten Produktstranges zu versehen.Furthermore it is e.g. it is also possible, when using the dispenser 1 as a strip dispenser to dispense pasty foodstuffs, to provide a spice paste within the strip chamber in order to provide the main food product to be dispensed, which is located within the container 2 and the pumping chamber 5, with a certain spice admixture distributed over the circumference of the dispensed product strand.

Dem Spender 1 nach der vorliegenden Erfindung öffnet sich somit ein Einsatzgebiet über den kosmetisch/medizinischen Bereich, den Bereich der Putz- und Pflegemittel, z.B. Schuhcremes, bis hin zur portionierten Bereitstellung pastöser Lebensmittel.The dispenser 1 according to the present invention thus opens up an area of application in the cosmetic / medical field, the area of cleaning and care products, e.g. Shoe creams up to the portioned provision of pasty foods.

Die Querschnittformgebung des Behälters 2 kann entsprechend den Wünschen der Anwender in weitem Rahmen variiert werden und z.B. außer kreiszylindrische Formen auch elliptische und andere zweiseitig symmetrische Querschnittsformen umfassen.The cross-sectional shape of the container 2 can be varied widely according to the wishes of the users and e.g. in addition to circular cylindrical shapes also include elliptical and other bilaterally symmetrical cross-sectional shapes.
