Description

Die Erfindung betrifft einen Spender für pastöse Massen bestehend aus einem rohrförmigen Behälter mit einer Mundstücksöffnung sowie einem in Richtung auf diese bewegbaren Kolben mit einem einseitig wirkenden Gesperre und einem mundstückseitig vorgesehenen Betätigungselement zur Bewegung des Kolbens, welches mit einem sich in Längsrichtung des Gehäuses erstrekkenden Stab gekuppelt ist, der mit dem Gesperre des Kolbens in Eingriff bringbar ist.The invention relates to a dispenser for pasty masses consisting of a tubular container with a mouthpiece opening and a piston movable in the direction thereof with a one-way locking mechanism and an actuating element provided on the mouthpiece side for moving the piston, which is coupled to a rod extending in the longitudinal direction of the housing is which can be brought into engagement with the locking mechanism of the piston.

Spender in Gestalt rohrförmiger Behälter mit einem mundstückseitigen Betätigungselement, bei denen ein auf die Mundstücköffnung zu verlagerbarer Kolben läuft, an dem ein Zugorgan angreift, sind z.B. aus der DE-C-261 954 bekannt. Bei diesem Spender besteht das Zugorgan aus einem Band, dessen unteres Ende an dem Kolben angreift und dessen mundstückseitiges Ende sich beim Betätigen der Betätigungselemente auf der Welle aufwickelt. Solche Spender sind herstellungstechnisch kompliziert; ihre Bedienung ist nachteilig. Insbesondere ist keine Einhandbedienung möglich.Dispensers in the form of tubular containers with an actuating element on the mouthpiece side, in which a piston which can be moved towards the mouthpiece opening and on which a pulling element engages, are e.g. known from DE-C-261 954. In this dispenser, the traction member consists of a band, the lower end of which engages the piston and the mouth end of which is wound on the shaft when the actuating elements are actuated. Such dispensers are technically complicated; their operation is disadvantageous. In particular, one-handed operation is not possible.

Ferner sind z.B. aus der DE-C-678 288 und FR-A-797 113, Spender bekannt, bei denen ein Kolben in einem zylindrischen Gehäuse mittels eines Stabes bewegt wird, wobei der Stab durch ein Betätigungselement verlagerbar und über ein einseitig wirkendes Klemmgesperre mit dem Kolben verbunden ist. Diese im Aufbau etwas einfacheren Spender gestatten zwar eine Einhandbedienung; sie besitzen jedoch den Nachteil, dass das Betätigungselement der Mundstücköffnung gegenüberliegt, was zu einer ungenauen und unhandlichen Bedienung führt. Ausserdem ist der Stab bei Betätigung, d.h. beim Entleerungsvorgang, auf Druck belastet und muss deshalb eine erhebliche Knickstabilität besitzen, was vor allem einen relativ grossen Querschnitt des Stabes voraussetzt, wodurch Füllvolumen für den Spender verlorengeht.Furthermore, e.g. known from DE-C-678 288 and FR-A-797 113, dispensers in which a piston is moved in a cylindrical housing by means of a rod, the rod being displaceable by an actuating element and connected to the piston via a one-way locking mechanism is. These dispensers, which are somewhat simpler in construction, allow one-handed operation; however, they have the disadvantage that the actuating element lies opposite the mouthpiece opening, which leads to inaccurate and unwieldy operation. In addition, the rod is actuated, i.e. during the emptying process, loaded under pressure and must therefore have considerable kink stability, which above all requires a relatively large cross section of the rod, as a result of which filling volume for the dispenser is lost.

Letzlich sind aus der US-A-3 255 935 Spender der eingangs geschilderten Art bekannt, bei denen zwar ein mundstückseitiges Betätigungselement vorgesehen ist, mit dem ein Stab gegen den Druck einer Feder durch einen Kolben-mit Gesperre geführt wird. Jedoch wird der Stab beim Niederdrücken des Betätigungselementes nicht in Ausgaberichtung verlagert, so dass man beim Betätigen nicht die Menge des abgegebenen Gutes dosieren kann. Die Abgabe erfolgt später, wenn der heruntergedrückte Stab den Kolben unter der Wirkung einer im Betätigungselement gesondert vorgesehenen Feder hochzieht. Abgesehen von der nicht gegebenen Möglichkeit einer Dosierung des Gutes ist der Einbau einer gesonderten Feder aufwendig. Bei einer anderen Ausführungsform dieser bekannten Spender (Fig. 5 in US-A-3 255 935) ist ein Wippenhebei als Betätigungselement am unteren Ende des Rumpfes des Behälters vorgesehen, was aber wiederum den Nachteil hat, dass der Stab beim Niederdrücken des Wippenhebels leer und entgegen der Ausgaberichtung läuft, so dass keine genaue Dosierung möglich ist. Ferner wird der Stab bei Förderung auf Druck beansprucht, was die bereits oben erwähnten Nachteile mit sich bringt. Darüber hinaus ist neben der umständlichen und ungenauen Handhabung des Bedienungselementes am Ende des Behälters auch die Herstellung und Befüllung derartiger Spender aufwendig. Aufgabe der vorliegenden Erfindung ist es, einen Spender der eingangs erwähnten Art so auszubilden, dass bei vereinfachter und gebrauchsgünstigerer Konstruktion eine erleichterte Handhabung, insbesondere eine bequeme Einhandbedienung verwirklicht ist, bei der auch die oben erwähnten Nachteile einer mangelhaften Dosierung und schlechten Befüllung beseitigt sind.Finally, from US-A-3 255 935 dispensers of the type described at the outset are known, in which a mouthpiece-side actuating element is provided, with which a rod is guided against the pressure of a spring by a piston with a ratchet. However, the rod is not displaced in the dispensing direction when the actuating element is depressed, so that the amount of the dispensed product cannot be metered out when actuated. The release takes place later when the depressed rod pulls up the piston under the action of a spring provided separately in the actuating element. Apart from the fact that there is no possibility of dosing the goods, the installation of a separate spring is complex. In another embodiment of these known dispensers (Fig. 5 in US-A-3 255 935) a rocker lift is provided as an actuating element at the lower end of the body of the container, which in turn has the disadvantage that the rod is empty and depressed when the rocker arm is depressed runs counter to the dispensing direction, so that exact dosing is not possible. Furthermore, the rod is stressed when it is conveyed, which has the disadvantages mentioned above. In addition to the cumbersome and imprecise handling of the control element at the end of the container, the manufacture and filling of such dispensers is also complex. The object of the present invention is to design a dispenser of the type mentioned at the outset in such a way that, with a simplified and more convenient construction, easier handling, in particular convenient one-hand operation, is achieved, in which the above-mentioned disadvantages of inadequate dosage and poor filling are eliminated.

Zur Lösung dieser Aufgabe wird daher ein Spender der oben erwähnten Art vorgeschlagen, der gekennzeichnet ist dadurch, dass

  • a) das Betätigungselement als Wippenhebel ausgebildet ist, dessen einer Arm mit dem Stab derart gekuppelt ist, dass letzterer bei Niederdrücken des Betätigungselementes in Ausgaberichtung verlagerbar ist, und dessen anderer Arm als Druckfläche des Betätigungselementes ausgebildet ist, und
  • b) der Stab und der Wippenhebel materialeinheitlich geformt sind.
To solve this problem, a donor of the type mentioned above is therefore proposed, which is characterized in that
  • a) the actuating element is designed as a rocker arm, one arm of which is coupled to the rod in such a way that the latter can be displaced in the dispensing direction when the actuating element is depressed, and the other arm of which is designed as a pressure surface of the actuating element, and
  • b) the rod and the rocker arm are made of the same material.

Es ist zwar in der älteren EP-A-0 028 727, die mit Ausnahme der Bundesrepublik Deutschland für die gemeinsamen Vertragsstaaten angemeldet wurde, ein ähnlicher Spender mit Rückschlagventil vorgeschlagen worden, bei dem gemäss einer Ausführungsform (Fig. 9) zur Betätigung des Kolbens ein Druckknopf vorgesehen ist, der über einen Hebel mit dem Stab zur Bewegung des Kolbens verbunden ist und mittels einer Spiralfeder als Rückstellorgan ausgerüstet ist. Diese Spenderbetätigung ist jedoch nicht nur aufwendig, sondern auch störanfällig.In the older EP-A-0 028 727, which was registered for the common contracting states with the exception of the Federal Republic of Germany, a similar dispenser with check valve has been proposed, in which according to one embodiment (FIG. 9) one is used to actuate the piston Push button is provided, which is connected via a lever to the rod for moving the piston and is equipped as a return element by means of a spiral spring. This dispenser operation is not only complex, but also prone to failure.

Mit der Erfindung wird nunmehr ein Spender vorgeschlagen, der folgende Merkmale bzw. Wirkungsweisen in sich vereint:

  • a) das Betätigungselement ist mundstückseitig vorgesehen,
  • b) das Betätigungselement ist als Wippenhebel ausgebildet, dessen einer Arm mit dem Stab gekuppelt und dessen anderer Arm als Druckfläche des Betätigungselementes ausgebildet ist,
  • c) der Stab wird bei Niederdrücken des Betätigungselementes in Ausgaberichtung verlagert,
  • d) der Stab ist während des Arbeitsschrittes auf Zug belastet, und
  • e) der Stab und der Wippenhebel sind materialeinheitlich geformt.
The invention now proposes a dispenser that combines the following features and modes of action:
  • a) the actuating element is provided on the mouthpiece side,
  • b) the actuating element is designed as a rocker arm, one arm of which is coupled to the rod and the other arm of which is designed as a pressure surface of the actuating element,
  • c) the rod is displaced in the dispensing direction when the actuating element is depressed,
  • d) the rod is subjected to tension during the work step, and
  • e) the rod and the rocker arm are made of the same material.

Durch die erfindungsgemässe Kombination von vier an sich bekannten Merkmalen und dem zusätzlichen Merkmal, dass der Stab und der Wippenhebel materialeinheitlich geformt sind, erhält man einen überaus praktischen, betriebssicheren, leicht herstellbaren und leicht befüllbaren Spender.The combination according to the invention of four features known per se and the additional feature that the rod and the rocker arm are formed from the same material results in a dispenser that is extremely practical, reliable, easy to manufacture and easy to fill.

Die Unteransprüche stellen vorteilhafte Weiterbildungen dieser Lösung dar.The subclaims represent advantageous developments of this solution.

Zufolge solcher Ausgestaltung ist ein herstellungstechnisch einfacher, gebrauchsvorteilhafter Spender geschaffen: Der über ein einseitig wirkendes Gesperre mit dem Kolben gekuppelte Stab wird beim Arbeitsschritt auf Zug belastet, so dass der Stab querschnittsgeringer ausgestaltet sein kann als ein unter Druckbelastung stehender Stab, bei dem vor allen Dingen unter Zugrundelegung grösserer Gehäuselängen die Gefahr einer Durchbiegung nicht auszuschliessen wäre. Der querschnittsreduzierte Stab kommt auch Bestrebungen hinsichtlich der Materialersparnis entgegen. Die Ausgabe des Füllinhalts erfolgt äusserst bedienungsbequen in kleinen Dosierschritten. Dazu sitzt das mundstückseitige Ende des Stabes an dem einen Arm eines doppelarmigen, im Gehäuse gelagerten Wippenhebels, dessen anderer Arm als Betätigungs-Druckfläche ausgebildet ist. Eine solche Wippe kann wie ein wechselseitig beaufschlagbarer Pumpenhebel bedient werden, indem der Betätigungsfinger wechselseitig verlagert drückt. Da die Mundstücköffnung in unmittelbarer Nähe des Wippenhebels liegen kann, ist eine solche Art der Betätigung ohne weiteres möglich, wobei die restlichen Finger der Hand den Behälter sicher umfassen, so dass eine genau plazierbare Abgabe des Füllinhalts ermöglicht ist. Von baulichem Vorteil ist vor allem auch die Massnahme, dass Stab und Wippenhebel materialeinheitlich geformt sind, also als ein zusammenhängendes Einsatzteil vorliegt. Die Gelenkzone zwischen beiden Funktionsteilen, nämlich Stab und Wippenhebel, wird in einfacher Weise dadurch erreicht, dass der Stab im Bereich seines Ansatzes eine querschnittsverjüngte Biegezone besitzt. Ein aus einem entsprechend flexiblen, elastischen Material gebildetes Einsatzteil ist dabei auch in der Lage, einander überlagernde lineare und kreisbogenförmige Bewegungen zu kompensieren. Statt einer wechselseitigen Wippenhebel-Betätigung kann auch eine einfachere einseitige Wippenhebel-Betätigung einfach dadurch erfolgen, dass der Wippenhebel in Richtung seiner Grundstellung federbelastet ist. Eine entsprechende Rückholfeder lässt sich unter Nutzung der Rückstellkraft des verwendeten Materials mit einfachsten Mitteln dadurch realisieren, dass die-Feder der Unterseite des Wippenhebels materialeinheitlich als Zunge angeformt ist. Eine sogar werkzeuglose Zuordnung dieses Einsatzbauteiles wird dadurch erreicht, dass der Wippenhebel im Bereich seines einen, kürzeren Arms in einer Ausnehmung einer Stufe einliegt, deren Ausnehmungs-Seitenflanken Lageröffnungen zum Einklipsen der Lagerzapfen des Wippenhebels aufweisen, und dessen längerer Arm über die Stufe frei so vorsteht, dass er eine Teilfläche der oberen Gehäusestirnwand übergreift, auf welcher sich die Feder abstützt. Hierbei ist es zudem günstig, wenn das Ende der Feder in eine Mulde der Gehäusestirnwand ragt. Um mit einfachen Mitteln sicherzustellen, dass beim Aufprellen des Kolbens die Klipslagerung unbeeinträchtigt bleibt, es entsteht eine Verlagerungstendenz in Richtung des Wippenhebels, ist eine vorteilhafte Vorkehrung dahingehend getroffen, dass der in Verlagerungsrichtung des Stabes mit dem Gehäuse verklipste Wippenhebel von einem etwa koaxial zum Stab liegenden Niederhalterdorn überfangen ist, welcher innenseitig an der Decke einer die Mundstücköffnung verschliessenden Schutzkappe sitzt. Eine solche Schutzkappe kann über ein Schnellgewinde aufgeschraubt werden. Der entsprechende Niederhalterdorn ist dem Bauteil im Wege der spritztechnischen Fertigung leicht anformbar. Die Schutzkappe erfüllt somit eine Mehrfachfunktion, indem sie die Betätigungstaste vor zufälligen Berührungen abdeckt, beim Füllvorgang die axiale Unverschieblichkeit des Stabes sichert und im übrigen das Mundstück verschliesst, so dass das Füllgut in diesem Bereich nicht an- bzw. austrocknen kann.As a result of such a design, a dispenser which is simple to use and advantageous in terms of production is created: the rod, which is coupled to the piston via a one-way locking mechanism, is subjected to tensile stress during the working step, so that the rod can be designed to have a smaller cross section than a rod which is under pressure, above all based on larger housing lengths, the risk of deflection could not be excluded. The reduced-section rod also meets efforts to save material. The filling contents are dispensed extremely conveniently in small dosing steps. For this purpose, the mouth end of the rod sits on one arm of a double-armed rocker arm mounted in the housing, the other arm of which is designed as an actuating pressure surface. Such a rocker can be operated like a pump lever which can be acted upon mutually by the actuating finger pressing in a mutually displaced manner. Since the mouthpiece opening can be in the immediate vicinity of the rocker arm, such a type of actuation is readily possible, the remaining fingers of the hand securely encompassing the container, so that the filling contents can be dispensed in an exactly placeable manner. The measure that the rod and the rocker arm are formed from the same material, that is to say as a coherent insert, is of particular structural advantage. The articulation zone between the two functional parts, namely the rod and the rocker arm, is achieved in a simple manner in that the rod has a bending zone which is tapered in cross section in the region of its attachment. An insert part formed from a correspondingly flexible, elastic material is also able to compensate linear and circular movements overlapping one another. Instead of a reciprocal rocker arm actuation, a simpler one-sided rocker arm actuation can also be carried out simply by the rocker arm being spring-loaded in the direction of its basic position. A corresponding return spring can be realized using the restoring force of the material used in the simplest of ways by the fact that the spring on the underside of the rocker arm is integrally formed as a tongue. An even tool-free assignment of this insert component is achieved in that the rocker arm lies in the region of its one, shorter arm in a recess of a step, the recess side flanks of which have bearing openings for clipping in the bearing pins of the rocker arm, and the longer arm of which projects freely over the step that it overlaps a partial surface of the upper housing end wall on which the spring is supported. It is also advantageous here if the end of the spring protrudes into a depression in the housing end wall. In order to ensure with simple means that the clip bearing remains unaffected when the piston bounces, and there is a tendency toward displacement in the direction of the rocker arm, an advantageous precaution is taken in such a way that the rocker arm clipped to the housing in the direction of displacement of the rod lies approximately coaxially with the rod Hold-down mandrel is overlaid, which sits on the inside of the ceiling of a protective cap closing the mouthpiece opening. Such a protective cap can be screwed on using a quick thread. The corresponding hold-down mandrel can be easily molded onto the component by means of injection molding. The protective cap thus fulfills a multiple function in that it covers the actuation key against accidental contact, secures the axial immovability of the rod during the filling process and, in addition, closes the mouthpiece so that the contents cannot dry or dry out in this area.

Der in Form eines rohrförmigen Gehäuses 1 ausgebildete Spender ist von einem zentral liegenden, glatten Stab 2 durchsetzt. Darauf läuft ein Kolben 3 als Pressboden. Die Lauffläche 3' des Kolbens führt sich an der zylindrischen Gehäuseinnenwandung 1'. Das Gehäuse 1 bildet im Bereich seiner oberen Stirnwand 1" ein dezentral liegendes Mundstück 4 aus, welches schliesslich in eine weiter querschnittsreduzierte Mundstücköffnung 4' übergeht.The dispenser designed in the form of a tubular housing 1 is penetrated by a centrally located, smooth rod 2. A piston 3 runs on it as a press base. The running surface 3 'of the piston runs on the cylindrical housing inner wall 1'. The housing 1 forms a decentralized mouthpiece 4 in the region of its upper end wall 1 ", which finally merges into a mouthpiece opening 4 'with a further reduced cross section.

Die Gehäusestirnwand 1" ist zentral durchbrochen. Die entsprechende Öffnung 5 wird vom Stab 2 nach aussen hin durchsetzt. Letzterer geht dort in einen Wippenhebel W über. Die entsprechende Doppelarmigkeit des Wippenhebels ist dergestalt, dass desssen einer, kürzerer Arm 6 über einen mit dem Wippenhebel verbundenen Ansatz 7 und eine anschliessende Gelenkstelle 8 mit dem axial verlagerbaren Stab in Verbindung steht.The housing end wall 1 "is perforated centrally. The corresponding opening 5 is penetrated to the outside by the rod 2. The latter merges there into a rocker arm W. The corresponding double-armed nature of the rocker arm is such that one, shorter arm 6 is connected to one with the rocker arm connected approach 7 and a subsequent joint 8 is connected to the axially displaceable rod.

Der andere, längere Arm 9 des Wippenhebels W dient als Betätigungs-Druckfläche. Er ist oberseitig zur Erhöhung der Griffigkeit quergerieft. Die Riefung ist mit 10 bezeichnet.The other, longer arm 9 of the rocker arm W serves as an actuating pressure surface. It is grooved across the top to increase grip. The grooving is designated 10.

Die Gelenkstelle 8 ist als zwischen Ansatz 7 und dem Stab 2 liegende, querschnittsreduzierte Biegezone in Art eines Filmscharniers realisiert. Die Länge dieser querschnittsreduzierten Biegezone berücksichtigt gewisse, aus der Kippbewegung des Wippenhebels W resultierende geringe Querverlagerungen aufgrund der bogenförmigen Bewegung des Wippenhebels.The articulation point 8 is realized as a bending zone of reduced cross-section lying between the projection 7 and the rod 2 in the manner of a film hinge. The length of this reduced-cross-section bending zone takes into account certain small transverse displacements resulting from the tilting movement of the rocker arm W due to the arcuate movement of the rocker arm.

Die Wippengelenkachse ist mit x-x bezeichnet. Durch Niederdrücken des Wippenhebels W im Bereich der Betätigungs-Druckfläche wird der Stab axial in Ausgaberichtung verlagert. Er ist also während des Arbeitsschritts auf Zug belastet. Der Kolben 3 wird dabei mitgeschleppt, so dass der pastöse Füllinhalt F über die Mundstücköffnung 4' dosierbar ausgebracht wird. Die Hublänge beträgt jeweils etwa 1-2 mm.The rocker joint axis is marked xx. By pressing the rocker arm W down in the area of the actuation pressure surface, the rod becomes axially displaced in the dispensing direction. It is therefore subject to tension during the work step. The piston 3 is dragged along so that the pasty filling content F is dispensed in a metered manner via the mouthpiece opening 4 '. The stroke length is about 1-2 mm each.

Dem Kolben ist ein einseitig wirkendes Klemmgesperre zugeordnet. Letzteres besteht aus einer auf der einen Breitseite des Kolbens 3 sitzenden Federscheibe 12. Diese besitzt radial einwärts gerichtete Zungen 13. Die Zungen 13 erstrecken sich in gleicher Winkelverteilung und sind in bezug auf die der Kolbenlage entsprechende Querebene abgebogen, derart, dass sie sich mit ihren Stirnkanten 13' unter Federspannung an der Mantelfläche des Stabes 2 ebenenversetzt abstützen. Ihre Schrägstellung ist der Mundstückseite abgewandt. Der Kolben 3 wird daher nur bei Niederdrücken des längeren Armes 9 des Wippenhebels W von dem axial in Mundstückrichtung gezogenen Stab 2 mitgeschleppt.A one-way locking mechanism is assigned to the piston. The latter consists of a spring washer 12 seated on one broad side of the piston 3. This has radially inwardly directed tongues 13. The tongues 13 extend in the same angular distribution and are bent with respect to the transverse plane corresponding to the piston position in such a way that they align with theirs Support end edges 13 'under spring tension on the lateral surface of the rod 2 at a level offset. Their inclination faces away from the mouthpiece side. The piston 3 is therefore only dragged by the rod 2 pulled axially in the direction of the mouthpiece when the longer arm 9 of the rocker arm W is depressed.

Nach anschliessendem Loslassen des Wippenhebels W tritt dieser federbelastet wieder in seine Grundstellung. Eine entsprechende Feder 14 ist der Unterseite des Wippenhebels, d.h. der Unterseite des längeren Armes 9 materialeinheitlich als Zunge angeformt. Sie wurzelt im freien Ende dieses Armes und verläuft bogenförmig in Richtung des Stabes 2. Die Feder 14 kann eine gewisse Vorspannung aufweisen. Um die Grundstellung exakt zu definieren, weist der relativ querschnittsdünne Stab 2 im Bereich der Öffnung 5 der Gehäusestirnwand 1" eine kegelstumpfförmige Verdikkung 15 auf, welche in einer formangepassten, trichterförmigen Verbreiterung der Öffnung 5 einliegt.After then releasing the rocker arm W, the spring-loaded lever returns to its normal position. A corresponding spring 14 is the underside of the rocker arm, i.e. the underside of the longer arm 9 integrally formed as a tongue. It is rooted in the free end of this arm and extends in an arc shape in the direction of the rod 2. The spring 14 can have a certain pretension. In order to precisely define the basic position, the rod 2, which is relatively thin in cross-section, has a truncated cone-shaped thickening 15 in the region of the opening 5 of the housing end wall 1 ″, which lies in a shape-matched, funnel-shaped widening of the opening 5.

Bei dieser Bewegung entgegen dem Arbeitsschritt wird der Kolben 3 nicht mitbewegt. Vielmehr tritt der Stab nach Loslassen der Betätigungs-Druckfläche zufolge der Kraft der Feder 14 alleine wieder in seine ursprüngliche Stellung zurück. Der Grund dafür ist der, dass der Kolben einerseits am Füllinhalb «klebt» und anderseits die periphere Reibungsfläche eine entsprechende Mitnahme verhindert. Die federnd anliegenden Zungen 13 gleiten dabei frei über die Mantelfläche des Stabes 2.During this movement against the work step, the piston 3 is not moved. Rather, the rod returns to its original position after releasing the actuating pressure surface due to the force of the spring 14 alone. The reason for this is that on the one hand the piston “sticks” to the filling half and on the other hand the peripheral friction surface prevents it from being carried along. The resilient tongues 13 slide freely over the lateral surface of the rod 2.

Da der Kolben 3 desweiteren an der der Mundstücköffnung zugekehrten Seite eine- bis auf die Mantelfläche des Stabes 2 reichende Dichtungslippe 16 ausbildet, ist auch ein Übertritt des Füllinhaltes F auf die gegenüberliegende Kolbenseite mit Sicherheit verhindert, so dass keine Verluste auftreten. Die entsprechend vorgestülpte Dichtungslippe 16 setzt sich im Anschluss an den die eigentliche Kolbengleitfläche 3' bildenden Abschnitt in eine auf der der Ausgaberichtung abgewandten Seite liegende Tasche 17 fort zur Einlagerung der Federscheibe 12. Es kann sich hier um Klipszungen handeln. Die Federscheibe 12 kann natürlich in den elastischen Kolbenkörper auch eingespritzt sein.Furthermore, since the piston 3 forms a sealing lip 16 on the side facing the mouthpiece opening, which extends as far as the outer surface of the rod 2, the contents F are also prevented from passing onto the opposite side of the piston, so that no losses occur. The corresponding protruding sealing lip 16 continues after the section forming the actual piston sliding surface 3 'into a pocket 17 lying on the side facing away from the dispensing direction for the incorporation of the spring washer 12. These can be clip tongues. The spring washer 12 can of course also be injected into the elastic piston body.

Das freie Ende des Stabes ist in einer zentral liegenden, dem Deckel 18 des Behälters 1 angeformten Hülse 19 gelagert, welche eine solche Höhe aufweist, die den Axialhub des Stabes berücksichtigt, so dass dort die axiale Führung auch dann beibehalten ist, wenn der Kolben 3 weiter in Ausgaberichtung verlagert ist.The free end of the rod is mounted in a centrally located sleeve 19 which is molded onto the cover 18 of the container 1 and which has a height which takes into account the axial stroke of the rod, so that there the axial guidance is maintained even when the piston 3 is further shifted in the output direction.

Der Deckel kann im Wege der Klipshalterung zugeordnet sein. Er weist eine nicht näher dargestellte Druckausgleichsöffnung auf.The lid can be assigned by means of the clip holder. It has a pressure equalization opening, not shown.

Die Wippenachse x-x ist in Form dem Wippenhebel W seitlich angeformter Achsstummel 11 realisiert. Letztere klipsen bei Zuordnung des Wippenhebels in korrespondierende Lageröffnungen 20 an den Seitenflanken 21 einer Ausnehmung 22 ein. Die entsprechende Ausnehmung 22 liegt im , Bereich einer Stufe St der oberen Gehäusestirnwand 1". Die horizontale, quer zum Stab 2 sowie versetzt zu diesem liegende Wippenhebel-Lagerung ist im oberen Bereich der Ausnehmung 22 vorgenommen, so dass aufgrund der Stufe und des damit gegenüber der oberen Ausnehmungszone abgesetzten tieferliegenden Stirnwandabschnittes 1"' ein Betätigungsfreiraum für das Absenken des längeren Armes 9 vorliegt. Der längere Arm steht entsprechend über die Stufe St vor. Wie aus Fig. 1 deutlich hervorgeht, weist die vom längeren Arm übergriffene Teilfläche der Gehäusestirnwand 1" eine schachtartige Mulde 23 auf, in die das freie Ende der Feder 14 geführt hineinragt.The rocker axis x-x is realized in the form of the rocker arm W laterally formed axle stub 11. When the rocker arm is assigned, the latter clip into corresponding bearing openings 20 on the side flanks 21 of a recess 22. The corresponding recess 22 is located in the area of a step St of the upper housing end wall 1 ″. The horizontal rocker arm mounting lying transversely to the rod 2 and offset to it is made in the upper area of the recess 22, so that due to the step and the opposite the upper recess zone of the lower end wall section 1 ″, there is an operating space for lowering the longer arm 9. The longer arm protrudes accordingly above the St level. As can be clearly seen from FIG. 1, the partial surface of the housing end wall 1 ″ encompassed by the longer arm has a shaft-like depression 23 into which the free end of the spring 14 protrudes.

Den Lageröffnungen 20 ist ein nach oben offener, sich in der Seitenflankenebene der Ausnehmung 22 verbreiternder Steckschacht 20' vorgelagert, so dass das Zuordnen des Wippenhebels praktisch selbstzentrierend erfolgt. Das lageröffnungsseitige Ende dieses Schachtes ist jedoch von geringerer Breite als der Durchmesser der Lageröffnung 20 beträgt, so dass die erläuterte Klipsverankerung erreicht wird.Upstream of the bearing openings 20 there is a plug-in shaft 20 'which widens in the side flank plane of the recess 22, so that the rocker arm is assigned practically self-centering. However, the end of this shaft on the bearing opening side is of a smaller width than the diameter of the bearing opening 20, so that the clip anchoring described is achieved.

Um restfrei entleeren zu können, kann der ausgabeseitige Bereich des Gehäuses im wesentlichen entsprechend der Kontur der Dichtungslippe 16 des Kolbens gestaltet sein.In order to be able to empty completely, the area on the output side of the housing can be designed essentially according to the contour of the sealing lip 16 of the piston.

Der gesamte Spenderkopf wird von einer Schutzkappe 24 überfangen, welche in Aufsteckrichtung durch eine Schulter 25 auf Höhe der Gehäusestirnwand 1" anschlagbegrenzt ist.The entire dispenser head is covered by a protective cap 24 which is stop-limited in the plug-on direction by a shoulder 25 at the level of the housing end wall 1 ".

Alle Bauteile sind zweckmässig aus thermoplastischem Kunststoff im Wege des Spritzgiessens hergestellt.All components are expediently made of thermoplastic by injection molding.

Die Schutzkappe 24 besitzt einen von ihrer Dekke 24' innenseitig ausgehenden Niederhalterdorn N (vergl. Fig. 3). Letzterer ist der Kappe gleich mit angeformt. Die Stirnfläche des konisch zulaufenden Dornes endet unmittelbar über dem Arm 6 des Wippenhebels W. Sinn und Zweck dieser Ausgestaltung ist es, zu unterbinden, dass beim Aufprellen des Kolbens 3 die dem Wippenhebel angeformten Achsstummel 11 aus der Ausnehmung 22 herausgedrückt werden. Dies ist in Fällen nicht auszuschliessen, in denen die Klipskräfte aufgrund möglicher unterschiedlicher Toleranzen für die in Richtung des Stabes liegende Klipshalterung nicht ausreichen. In solchen Fällen bildet der Niederhaltedorn ein entsprechenden Kräften gewachsenes Widerlager. Die Schutzkappe 24 selbst ist beispielsweise unter Anwendung eines Kurzgewindes am Gehäuse selbst gehalten. Wie aus Fig. 3 weiter hervorgeht, bildet die Schutzkappe im Bereich ihrer deckenseitigen Eckzone eine starke Fase aus. Diese ist der Schrägung des Mundstücköffnungsrandes angepasst, so dass dort eine das Austrocknen des Füllinhaltes verhindernde Dichtschliessung erreicht wird. Der Niederhalterdorn N liegt koaxial zum zentrisch liegenden Stab 2.The protective cap 24 has a hold-down mandrel N which extends from its cover 24 'on the inside (cf. FIG. 3). The latter is molded onto the cap. The end face of the tapered mandrel ends directly above the arm 6 of the rocker arm W. The purpose of this embodiment is to prevent the stub axle 11 formed on the rocker arm from being pressed out of the recess 22 when the piston 3 is bounced. This cannot be ruled out in cases where the clip forces are insufficient due to the possible different tolerances for the clip holder lying in the direction of the rod. In such cases, the hold-down mandrel forms an abutment that has grown correspondingly. The protective cap 24 itself is held, for example, using a short thread on the housing itself. As can further be seen from FIG. 3, the protective cap forms a strong chamfer in the area of its corner zone on the ceiling. This is adapted to the bevel of the mouthpiece opening edge, so that there is a sealing closure that prevents the contents from drying out. The hold-down mandrel N is located coaxially with the central rod 2.
