Abstract

A dispenser for the delivery of dosed quantities of a pasty substance comprises a receptacle having a push button mounted on the receptacle for movement upwardly and downwardly adjacent an end thereof. A rod extends through the receptacle and is connected at its inner end to a follower plunger. A substance flow tube has one end extending into the receptacle to the reservoir thereof for the pasty substance and an opposite end with a substance delivery orifice which extends out of the receptacle. A closing wall adjacent the tube closes the delivery orifice. The follower plunger is in sliding engagement with interior of the receptacle and it is movably engageable around the rod and is movable along the rod upon discharge of a substance through the delivery orifice. There is a connection between the plunger and at least one of the closing wall and the substance flow tube for shifting one end of the closing wall relative to the flow tube opening the delivery orifice for the delivery of the substance therethrough. The delivery plunger normally moves up the rod member during the dispensing movement effected by movement of the plunger manually. This contributes to the outflow of the pasty substance through the delivery tube and out through the orifice.

Description

Die Erfindung betrifft einen Pastenspender zur Abgabe dosierter Mengen von pastösen Stoffen, wie Zahncreme od. dgl., bestehend aus einem im wesentlichen zylindrischen Behälter (1) aus Kunststoff mit einem im Behälter (1) axial beweglich gelagerten Förderkolben (4), der mittels einer manuell betätigbaren, mit einem federelastischen Rückstellorgan versehenen Drucktaste (14/3) über ein, als Schubstange (5) ausgebildetes, eine Gehäusestirnwand (9) sowie den Förderkolben (4) durchragendes Kupplungsorgan (5) gegen diese Gehäusestirnwand (9) verschiebbar ist, wobei in einem rohrartigen, die Behälterstirnwand (9) überragenden Düsenstock (18/3) eine Ausgabeöffnung (20) angeordnet ist, die durch eine von der Drucktaste (14/3) betätigbare Schließwand (21/3) verschließbar ist.The invention relates to a paste dispenser for dispensing metered amounts of pasty substances, such as toothpaste or the like, consisting of an essentially cylindrical container (1) made of plastic with a delivery piston (4) which is axially movably mounted in the container (1) and which can be operated by means of a Manually operable pushbutton (14/3) provided with a resilient return element can be moved against this housing end wall (9) via a coupling end (9) designed as a push rod (5) and projecting through the delivery piston (4), whereby An outlet opening (20) is arranged in a tube-like nozzle stock (18/3) projecting above the container end wall (9) and can be closed by a closing wall (21/3) which can be actuated by the pushbutton (14/3).

Bei einem bekannten Pastenspender der gattungsgemäßen Art (DE-A-3 400 373) ist das Betätigungsorgan mit zwei Lagerstiften versehen, die drehbar in zwei aufrechtstehenden Wandelementen gelagert sind. Das Betätigungsorgan ist um die Achse der Lagerstifte hebelartig schwenkbar. Die Wandelemente bilden zusammen mit einer rohrartigen Ausgabetülle das Kopfteil eines zylindrischen Aufnahmebehälters. Das Betätigungsorgan weist eine Schließklappe auf, welche im Ruhezustand die Öffnung der Ausgabetülle verschließt. Auf der gegenüberliegenden Seite der Schließklappe ist am Betätigungsorgan unterseitig eine Rückstellfeder einstückig angeformt. Diese Rückstellfeder stützt sich an einer Gehäusestirnwand des Aufnahmebehälters ab, so daß im Ruhezustand die Ausgabetülle durch die Schließklappe sicher geschlossen ist. Schließklappenseitig ist das Betätigungsorgan mit einem flexiblen Verbindungselement versehen, das zwischen der Schwenkachse und der Schließklappe angeordnet ist und das Betätigungselement mit einem Kuplungsorgan verbindet. Das Kupplungsorgan ist als Hubstange ausgebildet, welche in ihrer Länge etwa der Länge des Aufnahmebehälters entspricht und einen im Aufnahmebehälter in axialer Richtung des Aufnahmebehälters verschiebbaren Förderkolben durchragt.In a known paste dispenser of the generic type (DE-A-3 400 373) the actuator is provided with two bearing pins which are rotatably mounted in two upright wall elements. The actuator can be pivoted like a lever about the axis of the bearing pins. The wall elements, together with a tubular dispensing spout, form the head part of a cylindrical receptacle. The actuator has a closing flap which closes the opening of the dispensing spout in the idle state. A return spring is integrally formed on the underside of the actuating member on the opposite side of the closing flap. This return spring is supported on a housing end wall of the receptacle, so that the dispensing spout is securely closed by the closing flap in the idle state. On the closing flap side, the actuating element is provided with a flexible connecting element which is arranged between the pivot axis and the closing flap and connects the actuating element to a coupling element. The coupling member is designed as a lifting rod, which corresponds approximately in length to the length of the receiving container and projects through a delivery piston which can be displaced in the axial direction of the receiving container in the receiving container.

Beim Betätigen des Betätigungsorgans wird das Kupplungsorgan in Richtung der Gehäusestirnwand gezogen. Der Förderkolben ist mit dem Kupplungsorgan durch ein Richtgesperre verbunden und folgt der Bewegung des Kupplungsorgans in Ausgaberichtung. Bei der Rückkehr in die Ruhestellung drückt die Rückstellfeder das Betätigungsorgan in seine Ausgangsstellung. Dabei wird über das Verbindungselement gleichzeitig das Kupplungsorgan nach unten durch den stillstehenden Förderkolben hindurch geschoben.When you press the actuator, it will Coupling member pulled towards the housing end wall. The delivery piston is connected to the coupling member by a directional lock and follows the movement of the coupling member in the direction of discharge. When returning to the rest position, the return spring presses the actuator into its initial position. The coupling element is simultaneously pushed down through the stationary delivery piston via the connecting element.

Da beim Betätigen des Betätigungsorgans der Förderhub des Förderkolbens gleichzeitig mit der Öffnungsbewegung der Schließklappe einsetzt, ist die Abgabetülle durch die Schließklappe bei Förderbeginn noch fast vollständig verschlossen. Das führt beim Förderbeginn zu einem unkontrollierten Pastenaustritt aus der Abgabetülle. Des weiteren bewegt sich beim Schließvorgang die Schließklappe im wesentlichen senkrecht auf die Öffnung der Ausgabetülle, so daß im Öffnungsbereich befindliche Pastenreste seitlich nach außen gequetscht werden. Das hat zur Folge, daß nach der Benutzung der Endbereich der Abgabetülle regelmäßig gereinigt werden muß.Since the delivery stroke of the delivery piston commences with the opening movement of the closing flap when the actuating member is actuated, the dispensing spout is almost completely closed by the closing flap at the start of delivery. This leads to an uncontrolled paste leakage from the dispensing spout at the start of funding. Furthermore, during the closing process, the closing flap moves essentially vertically onto the opening of the dispensing spout, so that paste residues located in the opening area are squeezed out laterally. As a result, the end area of the dispensing nozzle must be cleaned regularly after use.

Bei einem bekannten Pastenspender (DE-OS 31 04 726) besteht die Bedienungseinrichtung aus einem Hebel, der einstückig mit einem Verschlußteil verbunden ist, welches eine Ausgabeöffnung verschließt. Diese Bedienungseinrichtung ist in einem Kopfteil schwenkbar gelagert, wobei zwischen dem Hebel und dem Kopfteil eine Rückstellfeder angeordnet ist. Der Kopfteil ist auf einem Pastenbehälter aufgesteckt, wobei der Pastenbehälter zur Aufnahme des Kopfteils mit einem Halsstück versehen ist, das eine nach außen vorstehende Schulter aufweist. In dem im wesentlichen zylinderförmigen Pastenbehälter ist ein axial verschieblicher Förderkolben angeordnet, der über ein Richtgesperre mit einer den Förderkolben durchragenden Schubstange verbunden ist. Die Schubstange ist über eine gelenkige Verbindung mit dem Hebel verbunden und wird bei Betätigung des Hebels unter Mitnahme des Förderkolbens nach oben gezogen. Gleichzeitig mit dem Förderbeginn bzw. dem Druckaufbau im Pastenbehälter öffnet das Verschlußteil schieberartig die Ausgabeöffnung. Beim Schließvorgang bewegt sich die Stange nach unten durch den im Pastenbehälter leicht klemmenden Förderkolben. Bei jeder Betätigung des Hebels wird der Förderkolben um eine bestimmte Hublänge nach oben gezogen, um eine bestimmte Pastenmenge durch die Ausgabeöffnung zu fördern. Die oben erwähnte Ausgabeöffnung ist Teil eines Ausgabekanals, der mit seinem unteren Ende parallel zur Stange verläuft und in das Halsstück mündet. Das obere Ende des Ausgabekanals ist um 90° abgewinkelt und verläuft radial zum Pastenbehälter, wobei dessen Endstück die Ausgabeöffnung bildet. Der Förderkolben weist Entlüftungsklappen auf, die für ein einwandfreies Befüllen des Pastenbehälters erforderlich sind. Des weiteren ist der Pastenbehälter mittels einer Bodenplatte verschließbar.In a known paste dispenser (DE-OS 31 04 726), the operating device consists of a lever which is integrally connected to a closure part which closes a dispensing opening. This operating device is pivotally mounted in a head part, a return spring being arranged between the lever and the head part. The head part is plugged onto a paste container, the paste container being provided with a neck piece for receiving the head part, which has a shoulder projecting outwards. An axially displaceable delivery piston is arranged in the essentially cylindrical paste container and is connected via a directional lock to a push rod which projects through the delivery piston. The push rod is connected to the lever via an articulated connection and is pulled upwards when the lever is actuated, taking the delivery piston with it. Simultaneously with the start of conveyance or the build-up of pressure in the paste container, the closure part opens the discharge opening in a slide-like manner. During the closing process, the rod moves downwards through the delivery piston, which is slightly jammed in the paste container. Each time the lever is operated, the delivery plunger is pulled up a certain stroke length to deliver a certain amount of paste through the dispensing opening. The above-mentioned dispensing opening is part of a dispensing channel which runs with its lower end parallel to the rod and opens into the neck piece. The upper end of the output channel is angled by 90 ° and runs radially to the Paste container, the end piece of which forms the dispensing opening. The delivery plunger has ventilation flaps that are required for the paste container to be filled properly. Furthermore, the paste container can be closed by means of a base plate.

Dieser Pastenspender besteht, wenn man von einer abnehmbaren Schutzkappe absieht, aus insgesamt acht Einzelteilen, wobei die relativ komplizierte Ausgestaltung einen hohen Montageaufwand erfordert. Dadurch, daß bei beim Betätigen der Drucktaste gleichzeitig der Förderhub des Förderkolbens und das Öffnen der Ausgabeöffnung durch das Verschlußteil beginnt, ist die Ausgabeöffnung bei Förderbeginn noch fast vollständig verschlossen. Dadurch entsteht im Pastenbehälter ein Überdruck, der zu einem unkontrollierten Pastenaustritt führt. Bei einem kräftigen Tastendruck kann dies zu einer elastischen Verformung des Verschlußteils führen.Apart from a removable protective cap, this paste dispenser consists of a total of eight individual parts, the relatively complicated design requiring a high level of assembly effort. The fact that when the pushbutton is pressed simultaneously the delivery stroke of the delivery piston and the opening of the delivery opening through the closure part begin, the delivery opening is still almost completely closed at the start of delivery. This creates an excess pressure in the paste container, which leads to an uncontrolled paste leakage. If the button is pressed strongly, this can lead to elastic deformation of the closure part.

Bei einem weiteren bekannten Pastenspender (DE-OS 35 07 355) ist eine Ausgabetülle als rohrförmiger Körper ausgebildet, dessen unterer Abschnitt mit einem Innengewinde versehen und auf eine rohrförmige Hohlnabe eines Verdrängungskolbens aufgeschraubt ist, während sein oberer Abschnitt unter einem Winkel von 30° schräg zur Behälterachse verläuft. Die Ausgabeöffnung ist durch eine quer zu ihrer Achse bewegliche Schließwand verschließbar bzw. verschlossen, die einstückiger Bestandteil eines wippenartigen Betätigungshebels ist. Dieser Betätigungshebel ist durch seitliche zungenförmige Abschnitte auf Lagerzapfen der Ausgabetülle schwenkbar gelagert und im übrigen so angeordnet, daß sich diese Zungen an Querschultern des Gehäuses abstützen, wenn die Taste im Sinne einer Öffnungsbewegung um die Achse der Lagerzapfen verschwenkt wird. Durch diese Abstützung wird bei der Öffnungsbewegung zugleich eine Axialverschiebung sowohl der Ausgabetülle als auch des Verdrängungskolbens bewirkt. Zur Rückstellung sowohl des Verdrängungskolbens als auch der Ausgabetülle und des Betätigungshebels in ihre Ausgangspositionen ist zwischen der unteren Stirnfläche des die Ausgabetülle bildenden Rohrkörpers und einer Ringstützfläche der Behälterstirnwand eine Schraubdruckfeder aus Metall angeordnet.In another known paste dispenser (DE-OS 35 07 355), a dispensing spout is designed as a tubular body, the lower section of which is provided with an internal thread and is screwed onto a tubular hollow hub of a displacement piston, while its upper section is inclined at an angle of 30 ° to Container axis runs. The dispensing opening can be closed or closed by a closing wall movable transversely to its axis, which is an integral part of a rocker-type actuating lever. This actuating lever is pivotally supported by lateral tongue-shaped sections on the bearing spigot of the dispensing spout and, moreover, is arranged in such a way that these tongues are supported on transverse shoulders of the housing when the key is pivoted about the axis of the bearing spigot in the sense of an opening movement. This support simultaneously causes an axial displacement of both the dispensing spout and the displacement piston during the opening movement. In order to reset both the displacement piston and the dispensing spout and the actuating lever into their starting positions, a metal helical compression spring is arranged between the lower end face of the tubular body forming the dispensing spout and an annular support surface of the container end wall.

Dieser Pastenspender besteht ohne Schutzkappe und Bodenscheibe aus insgesamt sieben Einzelteilen. Ein dosiertes Ausgeben des im Behälter befindlichen Mediums ist nur dann mit Sicherheit gewährleistet, wenn sich im Vorratsraum des Behälters kein Luftkissen bzw. keine Luftblasen befinden, weil Luft bekanntlich kompressiebel ist. Des weiteren ist die Gefahr gegeben, daß bei der Rückstellung des Verdrängungskolbens über die Ausgabetülle Luft in den Pastenspender angesaugt wird, da die Schließwand erst nach vollständiger Rückstellung in die Ruhestellung die Ausgabeöffnung vollständig und annähernd luftdicht verschließt.This paste dispenser consists of a total of seven individual parts without a protective cap and base plate. A dosed delivery of the medium in the container is only guaranteed with certainty if there are no air cushions or air bubbles in the storage space of the container, because air is known to be compressible. Furthermore, there is a risk that the Resetting the displacement piston is sucked air into the paste dispenser via the dispensing spout, since the closing wall closes the dispensing opening completely and almost airtight only after it has been completely returned to the rest position.

Weil Pastenspender der gattungsgemäßen Art in sehr hohen Stückzahlen als Massen- und Wegwerfartikel hergestellt werden und deshalb sowohl bezüglich der benötigten Materialmenge mit möglichst geringem Aufwand herstellbar sein sollen, bringt jedes zusätzliche Einzelteil zusätzliche Werkzeugkosten und Montagekosten mit sich, verteuert also die Herstellung.Because paste dispensers of the generic type are manufactured in very large quantities as mass and disposable items and should therefore be able to be produced with as little effort as possible both in terms of the amount of material required, each additional individual part entails additional tool costs and assembly costs, thus making the production more expensive.

Der Erfindung liegt die Aufgabe zu Grunde, einen einhändig bedienbaren Pastenspender der eingangs genannten Art zu schaffen, bei dem mit einfachen Mitteln erreicht wird, daß beim Betätigen zunächst die Ausgabeöffnung zumindest teilweise freigegeben wird, bevor durch den Förderkolben Paste gefördert wird, wobei der Pastenspender aus möglichst wenig Einzelteilen bestehend mit einem geringst möglichen Aufwand an Material-, Werkzeug- und Montagekosten herstellbar sein soll.The invention has for its object to provide a one-handed paste dispenser of the type mentioned, in which it is achieved with simple means that when pressed, the dispensing opening is at least partially released before paste is conveyed by the feed piston, the paste dispenser being off as few individual parts as possible should be producible with the least possible effort in material, tool and assembly costs.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß das zur Rückstellung der Drucktaste (14/3) dienende federelastische Rückstellorgan (66, 67, 68) einstückig am Kupplungsorgan (5) angeformt ist und daß bei manueller Betätigung der Drucktaste (14/3) das Kupplungsorgan (5) durch das teilweise als Kipphebel wirkende Rückstellorgan (66, 67, 68) verzögert betätigt wird und einen Förderhub des Förderkolbens (4) bewirkt, nachdem die Ausgabeöffnung (20) von der Schließwand (21/3) zumindest teilweise freigegeben ist.According to the invention the object is achieved in that the for resetting the push button (14/3) serving resilient resetting member (66, 67, 68) is integrally formed on the coupling member (5) and that when the push button (14/3) is actuated manually, the coupling member (5) acts partially as a rocker arm Return element (66, 67, 68) is actuated with a delay and causes a delivery stroke of the delivery piston (4) after the discharge opening (20) is at least partially released from the closing wall (21/3).

Durch die Ausgestaltung der Erfindung nach den Ansprüchen 2, 3, 5 und 6 sind die Teile des Rückstellorgans und des Kupplungsorgans auf einfache Weise einstückig herstellbar.Due to the configuration of the invention according to claims 2, 3, 5 and 6, the parts of the restoring member and the coupling member can be produced in one piece in a simple manner.

Durch die Ausgestaltung der Erfindung nach Ansprüchen 4 und 7 wird erreicht, daß das Kupplungsorgan, welches mit dem Förderkolben über ein Richtgesperre verbunden ist beim Betätigen der Drucktaste verzögert angehoben wird, so daß die gemäß Anspruch 8 ausgebildete Drucktaste mit ihrer Schließwand bevor der eigentliche Förderhub beginnt, die Ausgabeöffnung des gemäß den Ansprüchen 8 und 9 ausgestalteten Düsenstocks zumindest zur Hälfte freigibt. Dadurch wird erreicht, daß sich im Pastenspender nicht unkontrolliert Druck aufbauen kann, und der Pastenspenderinhalt unkontrolliert aus der noch verschlossenen gequetscht wird.The embodiment of the invention according to claims 4 and 7 ensures that the coupling member, which is connected to the delivery piston via a directional lock, is raised in a delayed manner when the pushbutton is actuated, so that the pushbutton designed according to claim 8 with its closing wall begins before the actual delivery stroke begins , the output opening of the nozzle assembly designed according to claims 8 and 9 at least half. This ensures that pressure cannot build up in the paste dispenser in an uncontrolled manner, and that the paste dispenser contents remain uncontrolled closed squeezed.

Durch die Ausgestaltung der Erfindung nach Anspruch 10 sind die Mittel angegeben, durch die es auf einfachste Weise möglich ist, in dem aus der Ausgabeöffnung austretenden Pastenstrang zwei oder mehrere andersfarbige Pastenstreifen zu erzeugen.The configuration of the invention according to claim 10 provides the means by which it is possible in the simplest possible way to produce two or more differently colored paste strips in the paste strand emerging from the dispensing opening.

Anhand der Zeichnung wird im folgenden ein Ausführungsbeispiel der Erfindung näher erläutert. Es zeigt:

Der Pastenspender weist einen zylindrischen Behälter 1 auf, der mit einem erweiterten Sockelrand 2 versehen ist. Die Unterseite des Behälters kann offen oder durch einen nicht dicht schließenden Boden verschlossen sein. Funktionell ist ein solcher Boden ohne Bedeutung. Im Behälter ist ein ringsum dichtend an der Innenseite der Behälterwand 3 anliegender Kolben 4 verschiebbar angeordnet. Dieser Kolben 4 wird von einer gezahnten Schubstange 5 (Verzahnung nicht in Zeichnung dargestellt) betätigt, die eine zentrale Kolbennabe 6 durchragt und mit dieser durch ein Richtgesperre 88' derart zusammenwirkt, daß bei einer Aufwärtsbewegung der Schubstange in Richtung des Pfeiles 7 der Kolben 4 nach oben gefördert wird, während eine nachfolgende Abwärtsbewegung der Schubstange 5 bei stillstehendem Kolben 4 erfolgt. Die Schubstange 5 ist in einer zentralen Führungsnabe 8 einer Behälterstirnwand 9 axial beweglich geführt und die Abwärtsbewegung der Schubstange 5 wird durch einen auf der Oberseite der Behälterstirnwand 9 aufsitzenden Ringflansch 10 begrenzt.The paste dispenser has a cylindrical container 1, which is provided with an enlarged base edge 2. The bottom of the container can be open or closed by a bottom that does not close tightly. Functionally, such a floor is irrelevant. In the container, a piston 4, which rests around the inside of the container wall 3, is arranged so that it can move. This piston 4 is actuated by a toothed push rod 5 (toothing not shown in the drawing) which projects through a central piston hub 6 and interacts with it by a directional lock 88 'in such a way that when the push rod moves upwards in the direction of arrow 7, the piston 4 follows is promoted above, while a subsequent downward movement of the push rod 5 takes place with the piston 4 at a standstill. The push rod 5 is axially movably guided in a central guide hub 8 of a container end wall 9 and the downward movement of the push rod 5 is limited by an annular flange 10 seated on the upper side of the container end wall 9.

Gemäß Fig. 1 ist ein rohrartiger Düsenstock 18/3 mit seiner radial nach außen gerichteten Ausgabeöffnung 20 feststehend an der Behälterstirnwand 9 befestigt, während das Öffnen und Schließen dieser Ausgabeöffnung 20 durch eine axial bewegliche Schließwand 21/3 erfolgt. Der Düsenstock 18/3 ist exzentrisch zur Behälterachse 52 angeordnet. Der Düsenstock 18/3 ist einstückig an der Behälterstirnwand 9 des Behälters 1 angeformt und mit einer Schließwand 21/3 versehen, welche einstückiger Bestandteil einer im wesentlichen zylindrischen Hülse 53 ist, die in einem die Behälterstirnwand 9 stirnseitig überragenden Kragen 54 zwischen der Behälterstirnwand 9 und einem nach innen vorspringenden Ringbund 55 axial beweglich geführt ist. Dabei bildet die Schließwand 21/3 die eine Seitenwand eines pyramidenartigen Aufsatzes 56 der Stirnwand 57, deren Außenfläche zugleich Betätigungsfläche ist, so daß die gesamte Hülse 53 in diesem Falle die Drucktaste 14/3 darstellt. Damit sich die Hülse 53 aus dem Kragen 54 nicht mehr lösen kann, ist sie mit einem den Ringbund 55 untergreifenden Rastring 58 versehen.1, a tubular nozzle assembly 18/3 with its radially outward discharge opening 20 is fixedly attached to the container end wall 9, while the opening and closing of this discharge opening 20 is effected by an axially movable closing wall 21/3. The nozzle assembly 18/3 is arranged eccentrically to the container axis 52. The nozzle assembly 18/3 is integrally formed on the container end wall 9 of the container 1 and is provided with a closing wall 21/3, which is an integral part of an essentially cylindrical sleeve 53 which is in the end face of the container end wall 9 projecting collar 54 is axially movable between the container end wall 9 and an inwardly projecting collar 55. The closing wall 21/3 forms the one side wall of a pyramid-like attachment 56 of the end wall 57, the outer surface of which is also the actuating surface, so that the entire sleeve 53 in this case represents the pushbutton 14/3. So that the sleeve 53 can no longer be detached from the collar 54, it is provided with a locking ring 58 which engages under the annular collar 55.

An der Schubstange 5 sind, wie aus Fig. 2 ersichtlich ist, drei zick-zack-förmig verlaufende durch einen gemeinsamen Quersteg 65 miteinander verbundene Banddruckfedern 66, 67 und 68 angeformt. Während die mittlere Banddruckfeder 68 die Funktion einer Rückstellfeder und somit die Aufgabe hat, die Schubstange 5 jeweils wieder in ihre Ausgangslage zurückzudrücken, sind die beiden außenliegenden Banddruckfedern 66 und 67 an den jeweils außen liegenden Bogenabschnitten mit vertikalen Stützrippen 69, 70 und 71 bzw. 72, 73 und 73' versehen, die, wenn sie beim Herunterdrücken der Drucktaste 14/3 aufeinandertreffen, die Elastizität dieser Federn aufheben. Die unteren schrägen von außen nach innen verlaufenden Schenkel 74 bzw. 75 der Banddruckfedern 66 und 67 sind durch seitliche Versteifungsrippen 76 und 77 jeweils als biegesteife Doppelhebel ausgebildet, die jeweils auf einer vertikalen Lagerrippe 78 bzw. 79 der Behälterstirnwand 9 wippenartig aufsitzen und durch dünnere biegeelastische Verbindungsabschnitte 80 bzw. 81 mit der Schubstange 5 verbunden sind.On the push rod 5, as can be seen from FIG. 2, three zigzag-shaped band compression springs 66, 67 and 68 connected to one another by a common transverse web 65 are formed. While the middle band compression spring 68 has the function of a return spring and thus the task of pushing the push rod 5 back into its original position, the two outside band compression springs 66 and 67 are on the respective outer arc sections with vertical support ribs 69, 70 and 71 and 72 , 73 and 73 'which, when they meet when push button 14/3 is depressed, cancel the elasticity of these springs. The lower oblique legs 74 and 75 of the band compression springs 66 and 67, which run from the outside inwards, are each formed by rigid stiffening ribs 76 and 77 as rigid double levers, each of which rests on a vertical bearing rib 78 or 79 of the container end wall 9 in the manner of a rocker, and by thinner, flexible bends Connecting sections 80 and 81 are connected to the push rod 5.

Beim Betätigen der Drucktaste 14/3 erfolgt auf Grund dieser Ausgestaltung bevor die Schubstange 5 nach oben geschoben wird, zunächst ein Leerhub, durch den das Öffnen der Ausgabeöffnung 20 in Folge der Abwärtsbewegung der Schließwand 21/3 stattfindet, bis die Stützrippen 69 bis 73' jeweils paarweise aufeinander stoßen und bei weiterer Abwärtsbewegung die die Schubstange 5 nach oben ziehende Hebelwirkung an den Schenkeln 74 und 75 eintritt. Nach dem Loslassen der Drucktaste 14/3 bewirken diese Banddruckfedern 66, 67 und 68 das Schließen der Ausgabeöffnung 20 durch die Schließwand 21/3 und die Rückkehr der Schubstange 5 in die Ausgangsposition.When the pushbutton 14/3 is actuated, because of this configuration, before the push rod 5 is pushed upward, there is first an idle stroke, through which the opening of the dispensing opening 20 takes place as a result of the downward movement of the closing wall 21/3 until the supporting ribs 69 to 73 ' butt each other in pairs and upon further downward movement the lever 5 pulling the push rod 5 upwards occurs on the legs 74 and 75. After releasing the push button 14/3, these band compression springs 66, 67 and 68 cause the dispensing opening 20 to be closed by the closing wall 21/3 and the push rod 5 to return to the starting position.

Um bei dieser Ausführungsform in dem die Ausgabeöffnung 20 verlassenden Pastenstrang scharf konturierte Streifen einer andersfarbigen zweiten Paste erzeugen zu können, ist die Behälterstirnwand 9 auf ihrer Innenseite mit zwei von der Führungsnabe 8 zum Kanal 29/1 des Düsenstocks 18/3 führenden Leitrippen 83 und 84 versehen (Fig. 3), die sich in den Leitrippen 30/1 durch den Kanal 29/1 hindurch bis zur Ausgabeöffnung 20 hin fortsetzen. Durch diese Leitrippen 83 und 84 wird bewirkt, daß die andersfarbige Paste, die zur Streifenerzeugung benutzt werden soll und die in den in Fig. 3 kreuzweise schraffierten Flächenabschnitt der Innenseite der Behälterstirnwand 9 in einer nur wenige Millimeter dicken Schicht vorhanden ist, dem in diesem Falle mit einem quadratischen Querschnitt versehenen Kanal 29/1 nicht über dessen ganze Breitseite sondern nur außerhalb dieser Leitrippen 83 und 84 fließen kann, wobei jeweils außerhalb der sich im Kanal erstreckenden Leitrippen 30/1, in geringem seitlichen Abstand davon jeweils noch eine weitere sich ebenfalls im Kanal erstreckende Leitrippe 30/2 angeordnet ist. Die Leitrippen 30/1 und 30/2 bilden jeweils innerhalb des Kanals 29/1 Streifenkanäle für die andersfarbige Paste. An diese Leitrippen 30/2 schließen sich jeweils schräg verlaufende, an der Innenseite der Stirnwand angeordnete Leitrippen 85 und 86 an, welche den Aufnahmerahmen der zweiten andersfarbigen Paste begrenzen und die streifenartige Zufuhr dieser Paste zum Kanal 29/1 begünstigen. Unbedingt erforderlich sind die Leitrippen 85 und 86 jedoch nicht. Zur Streifenbildung genügt es, wenn die Leitrippen 83 und 84 in Kombination mit den Leitrippen 30/1 und 30/2 vorhanden sind. Allerdings könnten die Leitrippen 83 und 84 auch durch eine sich zwischen den Leitrippen 30/1 erstreckende Querrippe ersetzt werden, die verhindert, daß die andersfarbige zweite Paste in den zwischen den Leitrippen 30/1 liegenden Bereich in den Kanal 29/1 eindringen kann.In order to be able to produce sharply contoured strips of a different colored second paste in the paste strand leaving the discharge opening 20 in this embodiment, the inside of the container end wall 9 is provided with two guide ribs 83 and 84 leading from the guide hub 8 to the channel 29/1 of the nozzle assembly 18/3 provided (Fig. 3), which continue in the guide ribs 30/1 through the channel 29/1 to the dispensing opening 20. By means of these guide ribs 83 and 84 it is caused that the paste of a different color, which is to be used for producing the stripes, and which is present in the cross-hatched cross section in FIG. 3 of the inside of the container end wall 9 in a layer which is only a few millimeters thick, in this case with a square cross section provided channel 29/1 can not flow over its entire broad side but only outside these guide ribs 83 and 84, with each outside of the guide ribs 30/1 extending in the channel, at a small lateral distance from each other, also in each case Channel extending guide rib 30/2 is arranged. The guide ribs 30/1 and 30/2 each form 29/1 strip channels for the different colored paste within the channel. Adjacent to these guide ribs 30/2 are oblique guide ribs 85 and 86 arranged on the inside of the end wall, which limit the receiving frame of the second differently colored paste and favor the strip-like supply of this paste to the channel 29/1. However, the guide ribs 85 and 86 are not absolutely necessary. To form stripes, it is sufficient if the guide ribs 83 and 84 are present in combination with the guide ribs 30/1 and 30/2. However, the guide ribs 83 and 84 could also be replaced by a transverse rib extending between the guide ribs 30/1, which prevents the differently colored second paste from penetrating into the area 29 between the guide ribs 30/1 into the channel 29/1.

Der Vorteil der erfindungsgemäßen Ausgestaltung des Pastenspenders liegt nicht nur darin, daß durch das Lösungsprinzip lediglich fünf Teile benötigt werden, sondern daß die Einzelteile in sehr einfacher Weise, d.h. mit sehr geringen Montagekosten funktionsgerecht zusammensetzbar, also montierbar sind.The advantage of the configuration of the paste dispenser according to the invention is not only that only five parts are required by the solution principle, but that the individual parts are in a very simple manner, i.e. Can be assembled functionally with very low assembly costs, i.e. they can be assembled.

Der erfindungsgemäße Pastenspender hat zudem den Vorteil, daß mit der Betätigungstaste zugleich mittels einer Schubstange ein Förderkolben betätigt werden kann, wobei die Aufwärtsbewegung der Schubstange verzögert stattfindet und erst dann einsetzt, wenn die radial nach außen gerichtete Ausgabeöffnung des Düsenstockes durch die zusammen mit der Drucktaste nach unten bewegte Schließwand zumindest teilweise geöffnet ist. Dadurch werden Überdrücke, die zu unkontrolliertem Pastenaustritt aus der Ausgabeöffnung führen könnten, vermieden.The paste dispenser according to the invention also has the advantage that a delivery plunger can be actuated with the actuating button at the same time by means of a push rod, the upward movement of the push rod taking place with a delay and only starting when the radially outward-opening dispensing opening of the nozzle assembly by means of the together with the push button closing wall moved below is at least partially open. This avoids overpressures that could lead to uncontrolled paste leakage from the dispensing opening.
