Abstract

The dispenser for viscous materials has a housing (1), having a piston (2) which can only be displaced in the emptying direction, and an outlying actuating handle (B), by means of which a force can be applied to a pump element which can be compressed in the direction of the piston (2), the pump element having an inlet valve (V1) and an outlet valve (V2), and the outlet valve (V2) being arranged in the actuating handle (B), the outlet valve (V2), moreover, being spring- loaded in its closed position by means of spring elements which are moulded on and project into the interior of the dispenser. For a design which is simple in terms of manufacture and offers advantages in use, provision is made for the spring elements to be constructed as spring legs (21) which are supported on a collar (22) of the actuating handle (B) and are moulded directly onto the valve disc (20) in a free-standing manner. <IMAGE>

Description

Die Erfindung betrifft einen Spender für pastöse Massen, mit einem einen nur in Entleerungsrichtung verlagerbaren Kolben aufweisenden Gehäuse und einer außenliegenden Betätigungs­handhabe, mittels welcher auf ein in Richtung des Kolbens zusammendrückbares Pumpelement einwirkbar ist, wobei das Pumpelement ein Eingangs- und ein Ausgangsventil aufweist, und das Ausgangsventil in der Betätigungshandhabe angeordnet ist, und wobei weiter das Ausgangsventil in seiner Schließ­stellung federbelastet ist mittels in das Innere des Spen­ders ragender, angeformter Federelemente.The invention relates to a dispenser for pasty masses, with a housing which has a piston which can only be displaced in the emptying direction and an external actuating handle by means of which a pump element which can be compressed in the direction of the piston can be acted on, the pump element having an inlet and an outlet valve, and that Output valve is arranged in the actuating handle, and wherein the output valve is further spring-loaded in its closed position by means of molded spring elements projecting into the interior of the dispenser.

Bei einem markterhältlichen Spender sitzt das Ausgangsventil in einem einwärts gerichteten Fortsatz der Betätigungshandha­be. Die über dem Ausgangsventil liegende Auslaßöffnung des diesbezüglichen Pumpelements wird durch einen besonderen Stopfen geschlossen. Letzterer ist an einem randgelagerten Klappdeckel angeformt. Bestandteil des Pumpelements ist außer Eingangs- und Ausgangsventil auch ein in einem die Pumpkammer bildenen Zylinder gelagerter Kolben. Der erläuter­te Stopfenverschluß führt in der Regel zu einem Verdrängen der in der Austrittsöffnung verbleibenden pastösen Masse, die sich dann zwischen Handhabenobenseite und Schließdeckel­unterseite ausbreitet. Das stößt aus ästhetischen Gründen in der Regel auf Vorbehalt. Wird andererseits das Verschließen vergessen, besteht die Gefahr des Andickens bzw. Eintrock­nens der ausgabeseitigen Restmasse.In a dispenser available on the market, the outlet valve is located in an inward extension of the actuating handle. The outlet opening of the relevant pump element located above the outlet valve is closed by a special plug. The latter is molded onto a hinged lid mounted on the edge. In addition to the inlet and outlet valve, a component of the pump element is also a piston mounted in a cylinder forming the pump chamber. The plug closure explained generally leads to displacement of the pasty mass remaining in the outlet opening, which then spreads out between the top of the handle and the underside of the closing cover. For aesthetic reasons, this is usually met with reservations. If, on the other hand, the closure is forgotten, there is a risk of thickening or drying out of the residual mass on the output side.

Aufgabe der Erfindung ist es, in herstellungstechnisch einfa­cher, gebrauchsvorteilhafter Weise einen gattungsgemäßen Spender anzugeben, bei dem die Austrittsöffnung stets nach Betätigung gleichsam automatisch wieder verschlossen wird.The object of the invention is to provide a generic dispenser in a technically simple, advantageous manner in terms of use, in which the outlet opening is always automatically closed again after actuation, as it were.

Gelöst ist diese Aufgabe durch die im Anspruch 1 angegebene Erfindung.This object is achieved by the invention specified in claim 1.

Die Unteransprüche sind vorteilshafte Weiterbildungen des erfindungsgemäßen Spenders.The subclaims are advantageous developments of the dispenser according to the invention.

Zufolge solcher Ausgestaltung ist ein gattungsgemäßer Spen­der von erhöhtem Gebrauchswert erzielt: Ein besonderer Stop­fen einschließlich des zugehörigen Trägers wird verzichtbar. Den Verschluß der Auslaßöffnung übernimmt das Auslaßventil selbst. Die baulichen Mittel sind einfach und im Hinblick auf montagetechnische Bedingungen überraschend günstig. Konkret ist so vorgegangen, daß die Federelemente als sich an einem Kragen der Betätigungshandhabe abstützende, an dem Ventilteller freistehend unmittelbar angeformte Federbein­chen ausgebildet sind. Auf diese Weise kann die Betätigungs­handhabe im Wege der Vormontage bestückt und so der Spender­mechanik einfachst einverleibt werden. Die Federbeinchen stützen sich an der Betätigungshandhabe selbst ab. Ihre Lage ist exakt definiert bzw. trotz Hineinragens in das Pumpele­ment nicht beeinträchtigbar. Dabei ist es für die Einlage­rung des Ausgangsventils insgesamt vorteilhaft, daß sein Ventilteller in einem nach außen hin sich öffnenden Konus sitzt und in die Ventilöffnung eingepaßt ist. Zum Einsetzen des Ventiltellers brauchen daher lediglich die Federbeinchen gebündelt und durch die Ventilöffnung hindurchgesteckt zu werden. Um bezüglich der Federbeinchen zu einem zufrieden­stellenden Längungsvorrat zu kommen, wird weiter so vorgegan­gen, daß die Federbeinchen zunächst zu einer Mittelachse des Spenders parallel verlaufend ausgebildet sind und sich so­dann unter Abknickung an dem Kragen abstützen. Sowohl für eine geschützte Einlagerung des relativ empfindlichen Feder­ körpers als auch für eine möglichst gedrungene Bauform des Pumpelements erweist es sich als vorteilhaft, daß die Ausfe­derungslänge der Federbeinchen innerhalb des Kragens angeord­net ist. Dem Kragen kommt somit eine weitere Funktion zu; er dient nicht nur als Strömungsbrücke für das auszugebene Medium, sondern bildet zugleich eine Federkammer. Darüberhin­aus erweist es sich als günstig, wenn die Federbeinchen hakenartig einen Stirnbereich des Kragens übergreifen. Dies führt zu einer besonders lagegesicherten Positionierung des Feder/Ventilkörpers. Weiter wird vorgeschlagen, daß die Betätigungshandhabe zur Bildung einer Ausstreichfläche im wesentlichen konkav ausgebildet ist. Für mehr flüssigere Medien liegt insoweit sogar eine Art Auffangschale vor, wobei die allseitig höher liegende Peripherie als nicht benetzter Betätigungsbereich verbleibt. Im Hinblick auf ein restfreies Ausstreichen der freigegebenen pastöse Masse oder dergleichen, ist es nützlich, daß der Ventilteller außensei­tig in Schließstellung in die Betätigungshandhabe ebenen­gleich eingepaßt ist. Der Benutzer findet dadurch keinerlei störende Vorsprünge vor. Die Ausstreichfläche wird besser saubergehalten. Weiter wird vorgeschlagen, daß der Kragen der Betätigungshandhabe ein Führungskragen ist, geführt in einem einen Außenkragen aufweisenden Balg des Pumpelements. Gemeint ist nicht eine Verschiebeführung, sondern eine Auf­steckführung, also Steckzuordnung. Der peripher am Außenkra­gen wurzelnde Balg ist so zuordnungsicher angebunden. Weiter bringt die Erfindung in Vorschlag, daß der Kragen der Betäti­gungshandhabe mit Abstand zu dem unteren Rand des Außenkra­gens endet und daß in der sich ergebenden Stufe die Feder­beinchen Anlage finden. Auf diese Weise sind sogar die Veran­kerungszonen der Federbeinchen geschützt eingelagert. Außer­dem ergibt sich eine definierte periphere Abstützung für diese Enden. Baulich vorteilhaft ist es weiter, daß der Balg im wesentlichen kuppelförmig ausgebildet ist und über Abdich­tungsbereiche mit einer das Eingangsventil tragenden Decke des Gehäuses zusammenwirkt. Bezüglich der Decke kann es sich um ein Zusatzbauteil handeln oder aber um eine direkte Anfor­ mung, wobei zum Einführen des Kolbens dann natürlich die der Betätigungshandhabe abgewandte Endseite des Gehäuses offen zu halten wäre, dies dann auch aus fülltechnischen Gründen. Die kuppelförmige Gestalt trägt zur angestrebten gedrungenen Bauform bei. Günstig ist es in dichtungstechnischer Hin­sicht, daß zumindest einer der Dichtbereiche den Balg radial außen umgibt. Endlich bringt die Erfindung noch in Vor­schlag, daß das Eingangsventil in seinem Durchmesser im wesentlichen dem Durchmesser des Außenkragens entspricht und fluchtend zum Außenkragen angeordnet ist, und der Abstand der Unterseite zum Eingangsventil etwa einem Drittel bis der Hälfte des Durchmessers des Eingangsventiles entspricht. Die entsprechende Maßnahme führt zu einer kontrollierten Ausga­be. Bei extremem axialen Hub fährt der Außenkragen schließend gegen das Ausgabeventil.As a result of such an embodiment, a generic dispenser of increased utility value is achieved: a special stopper including the associated carrier is dispensable. The outlet valve closes the outlet opening itself. The structural means are simple and surprisingly inexpensive in terms of assembly technology. Specifically, the procedure is such that the spring elements are designed as spring struts which are supported on a collar of the actuating handle and are free-formed directly on the valve plate. In this way, the actuating handle can be pre-assembled and thus the dispenser mechanism can be easily incorporated. The struts support themselves on the operating handle. Their position is precisely defined or cannot be impaired despite protruding into the pump element. It is advantageous for the emplacement of the outlet valve overall that its valve disk sits in a cone that opens outwards and is fitted into the valve opening. To insert the valve plate, therefore, only the struts need to be bundled and inserted through the valve opening. In order to obtain a satisfactory amount of elongation with respect to the strut, the procedure is further such that the strut is initially designed to run parallel to a central axis of the dispenser and is then supported on the collar by kinking. Both for protected storage of the relatively sensitive spring body as well as for a compact design of the pump element, it proves to be advantageous that the rebound length of the strut is arranged within the collar. The collar thus has another function; it not only serves as a flow bridge for the medium to be dispensed, but also forms a spring chamber. In addition, it proves to be advantageous if the strut hooks overlap an end region of the collar. This leads to a particularly secure positioning of the spring / valve body. It is further proposed that the actuating handle is essentially concave to form a strike-out area. There is even a kind of drip tray for more fluid media, with the periphery, which is higher on all sides, remaining as a non-wetted actuation area. With regard to a completely free spreading of the released pasty mass or the like, it is useful that the valve plate is fitted on the outside in the closed position in the actuating handle at the same level. The user will not find any annoying projections. The spreading area is better kept clean. It is further proposed that the collar of the actuating handle is a guide collar, guided in a bellows of the pump element having an outer collar. What is meant is not a sliding guide, but a push-on guide, i.e. plug-in assignment. The bellows, which is rooted peripherally on the outer collar, is thus securely connected. Furthermore, the invention proposes that the collar of the actuating handle ends at a distance from the lower edge of the outer collar and that the struts find contact in the resulting step.

The dome-shaped shape contributes to the desired compact design. In terms of sealing technology, it is favorable that at least one of the sealing areas surrounds the bellows radially on the outside. Finally, the invention also proposes that the diameter of the inlet valve substantially corresponds to the diameter of the outer collar and is aligned with the outer collar, and that the distance from the underside to the inlet valve corresponds to approximately one third to half the diameter of the inlet valve. The corresponding measure leads to a controlled expenditure. With an extreme axial stroke, the outer collar closes against the dispensing valve.

Die öffnungsseitige Topfhälfte bildet mantelseitig eine nach oben gerichtete Abstreiflippe 2′ und in Nähe des Topfrandes eine Führungsrippe 2˝ aus. Abstreiflippe 2′ und Führungsrip­pe 2˝ führen sich an der zylindrischen Gehäuseinnenwandung 1′.The cylindrical housing 1 of the dispenser contains a piston 2. The latter is pot-shaped. The opening-side pot half forms an upward wiping lip 2 'on the casing side and a guide rib 2' in the vicinity of the pot edge. Wiping lip 2 'and guide rib 2' lead to the cylindrical housing inner wall 1 '.

Das Gehäuse 1 ist als nach oben offener Tiegel oder Topf realisiert. Dessen Topfboden 3 bildet peripher einen Stand­sockel 3′. Zentralliegend hat der Topfboden 3 eine Durchbre­chung 4 zum Luftausgleich bei der in der Gebrauchsphase ausschließlich nach oben, d. h. in Richtung des Pfeiles x stattfindenden Kolbenverlagerung. Natürlich hat die Durchbre­chung 4 die entsprechende Bedeutung auch beim Einsenken des dichtenden Kolbens 2 in das topfförmige Gehäuse 1.The housing 1 is realized as a crucible or pot open at the top. Whose pot bottom 3 forms a peripheral base 3 '. Centrally located, the pot bottom 3 has an opening 4 for air balance in the use phase only upwards, d. H. piston displacement taking place in the direction of arrow x. Of course, the opening 4 has the corresponding meaning even when the sealing piston 2 is countersunk into the cup-shaped housing 1.

Am dem dem Topfboden 3 gegenüberliegenden Ende befindet sich der die Ausgabemechanik enthaltende Kopf K des Spenders. Bestandteil der Ausgabemechanik ist ein Pumpelement, beste­hend aus einem flexiblen Balg 5, welcher eine Pumpkammer 6 domartig überfängt und in der Decke 7 des Spenders befestigt ist.At the end opposite the pot bottom 3 is the dispenser head K containing the dispensing mechanism. Part of the dispensing mechanism is a pump element, consisting of a flexible bellows 5, which extends over a pump chamber 6 like a dome and is fastened in the ceiling 7 of the dispenser.

Die Decke 7 besteht beim vorliegenden Ausführungbeispiel aus einem Einsatz 8.In the present exemplary embodiment, the blanket 7 consists of an insert 8.

Bestandteil des Pumpelements sind weiter ein Eingangsventil V1 und ein Ausgangsventil V2. Das Eingangsventil V1 sitzt im Mittelbereich 7′ der Decke 7. Dieser Mittelbereich ist gegen­über dem restlichen, peripheren Ringabschnitt der Decke 7 in Richtung der vom Gehäuse 1 gebildeten, die pastöse Masse M enthaltenden Vorratskammer 9 hin leicht abgesenkt. Hieraus ergibt sich eine definierte Steckmulde für den zylindri­schen, stirnseitig zugespitzten Wandungsbereich 10 des Bal­ges 5. Über den Absenkbereich hinaus formt die Übergangsstel­le zwischen dem Mittelbereich 7′ und dem peripheren Restbe­reich eine Ringnut 11. In diese hineingesteckt, bringt der Wandbereich 10 praktisch eine doppelseitige Abdichtung, d. h. außen und innen. Der äußere Dichtbereich setzt sich bis auf Höhe der Wölbungszone des Balges 5 fort. Es handelt sich um eine Ringwand 12. Letztere entspringt der Oberseite der Decke 7 und geht in einen einwärts gerichteten Vorsprung 13 über. Untergriffen ist dieser Vorsprung von einer in Gegenrichtung ausladenden Ringrippe 14 des Balges 5. Die Ringrippe 14 weist dreieckigen Querschnitt auf. Die eine Querschnittsseite wurzelt in der Mantelfläche des Wandungsbe­reiches 10, welcher Wandungsbereich sich über den dortigen Wölbungsansatzbereich des Domes hinaus nach oben hin gleich­gerichtet fortsetzt. Die entsprechende Materialanhäufung führt zu einer wesentlichen Verankerungsstabilisierung. Die in Einsteckrichtung des Balges liegende Flanke der Ringrippe 14 ist etwas flacher gestaltet als die rückwärtige Flanke, so daß das Verrasten des Balges 5 an der Decke 7 erleichtert ist, andererseits aber im verbundenen Zustand eine nahezu unlösbare Positionierung vorliegt.An input valve V1 and an output valve V2 are also part of the pump element. The input valve V1 sits in the central region 7 'of the ceiling 7. This central region is slightly lowered towards the rest of the peripheral ring portion of the ceiling 7 in the direction of the storage chamber 9 formed by the housing 1 and containing the pasty mass M. This results in a defined trough for the cylindrical, tapered wall area 10 of the bellows 5. Beyond the lowering area, the transition point between the central area 7 'and the peripheral remaining area forms an annular groove 11. Inserted into this, the wall area 10 practically provides a double-sided seal , ie outside and inside. The outer sealing area continues up to the level of the bulging zone of the bellows 5. It is an annular wall 12. The latter originates from the top of the ceiling 7 and merges into an inward projection 13. This projection is undercut by an annular rib 14 of the bellows 5 which protrudes in the opposite direction Ring rib 14 has a triangular cross section. One cross-sectional side is rooted in the lateral surface of the wall area 10, which wall area continues in the same direction upwards beyond the arching area of the dome there. The corresponding accumulation of material leads to a substantial stabilization of the anchorage. The flank of the annular rib 14 lying in the direction of insertion of the bellows is somewhat flatter than the rear flank, so that the latching of the bellows 5 on the ceiling 7 is facilitated, but on the other hand in the connected state there is an almost undetachable positioning.

Das als Rückschlagventil gestaltete Eingangsventil V1 ist eine Ventilklappe 15, welche über ein seitliches Filmschar­nier 16 an der Decke 7 bzw. dem Mittelbereich 7′ angebunden ist. Die Ventilsitzfläche befindet sich auf der Oberseite des besagten Mittelabschnitts 7′.The input valve V1 designed as a check valve is a valve flap 15, which is connected via a lateral film hinge 16 to the ceiling 7 or the central region 7 '. The valve seat is on the top of said middle section 7 '.

Der in Richtung des Kolbens 2 zusammendrückbare Balg 5 steht mit einer außenliegenden Betätigungshandhabe P in Verbin­dung. Es handelt sich um einen tellerförmigen Grundkörper mit nach unten abgewinckeltem Rand 16, welcher über eine rotationssymetrische Querrundung 17 in die gleichmäßig konka­ve Muldung einläuft. Dieser gemuldete Bereich bildet eine Ausstreichfläche 18 für die dosiert im Zentrum ausbringbare pastöse Masse M. Das Zentrum formt dazu eine Austrittsöff­nung aus, die in Grundstellung des Spenders vom Ventilteller 20 des Ausgangsventils V2 verschlossen gehalten wird.The bellows 5, which can be compressed in the direction of the piston 2, is connected to an external actuating handle P. It is a plate-shaped base body with angled-down edge 16, which runs into the uniformly concave trough via a rotationally symmetrical transverse rounding 17. This troughed area forms a spreading area 18 for the pasty mass M which can be dispensed in the center. For this purpose, the center forms an outlet opening which is kept closed by the valve plate 20 of the outlet valve V2 in the basic position of the dispenser.

Die den Ventilteller 20 aufnehmende Austrittsöffnung 19 ist als nach außen öffnender Hohlkonus realisiert, der Ventiltel­ler 20 also in die Austrittsöffnung 19 bzw. Ventilöffnung eingepaßt. Der Ventilteller 20 füllt die Öffnung völlig aus. Er überragt die Unterseite der von einer relativ dünnen Wandung gebildeten Betätigungshandhabe B geringsfügig. Außen­seitig bzw. oberseitig verbleibt dagegen eine ebenengleiche Ausrichtung zur Austreichfläche 18. Die über den Ringspalt zwischen Ventilteller 20 und der die Ventilsitzfläche bilden­den Ventilöffnung 19 austretende pastöse Masse kann so wie aus einem glatten Teller entnommen werden.The outlet opening 19 receiving the valve plate 20 is realized as an outwardly opening hollow cone, that is to say the valve plate 20 is fitted into the outlet opening 19 or valve opening. The valve plate 20 completely fills the opening. It slightly projects beyond the underside of the actuating handle B formed by a relatively thin wall. On the outside or on the top, on the other hand, there remains a level alignment with the spreading surface 18. The over the annular gap between the valve plate 20 and the pasty mass exiting the valve seat surface forming valve opening 19 can be removed as from a smooth plate.

Der Ventilteller 20 des Ausgangsventils V2 wird mittels Federelementen in seiner schließgerechten Grundstellung gehalten. Bezüglich der Federelemente handelt es sich um Federbeinchen 21. Letzte wurzeln an der Unterseite des Ven­tiltellers 20. Sie sind diesem freistehend unmittelbar ange­formt, und zwar in Randnähe. Mindestens zwei diametral einan­der gegenüberliegende Federbeinchen 21 bewirken, leicht vorgespannt, die Ventil-Schließstellung. Ihre Abstützung finden die Federbeinchen 21 an einem Kragen 22. Dieser Kra­gen 22 wurzelt an der Unterseite der Betätigungshandhabe B. Er ist als konzentrisch zur ventilsitzbildenden Austrittsöff­nung 19 bzw. Längsmittelachse x-x des Spenders verlaufende, zylindrische Ringwand realisiert.The valve plate 20 of the output valve V2 is held in its basic position suitable for closing by means of spring elements. With regard to the spring elements, the struts are 21. The last roots are on the underside of the valve plate 20. They are formed on the free-standing plate directly, in the vicinity of the edge. At least two diametrically opposed struts 21, slightly preloaded, bring about the valve closed position. The struts 21 are supported on a collar 22. This collar 22 is rooted on the underside of the actuating handle B. It is realized as a cylindrical ring wall running concentrically with the outlet opening 19 forming the valve seat or the longitudinal center axis x-x of the dispenser.

Die axiale Abstützfläche bildet das freie Stirnende 22′ des Kragens 22, auf das sich das senkrecht zur Längsmittelachse x-x nach auswärts abgewinkelte freie Ende 21′ der Federbein­chen 21 abstützt. Es kann auch eine Art Hinterschnitt-Ver­krallung realisiert sein. Die Federbeinchen 21 sind sodann in nach oben zum Zentrum hin konvergierender Abschrängung in den parallel zur Längsmittelachse x-x verlaufenden Abschnitt überführt. Die entsprechende Abknickung bringt den federnden Längungsvorrat. Da die entsprechende Ausfederungslänge der Federbeinchen innerhalb des Kragens 22 untergebracht ist, kommt diesem außer als Leitungsbrücke für die pastöse Masse M auch noch die Funktion einer Federkammer zu. Zur Zuordnung des so gestalteten Ausgangsventils V2 bedarf es lediglich des Bündelns der Federbeinchen 21, so daß diese durch die verengte Eintrittsöffnung 19 hindurchgeführt werden können unter Einschieben in die querschnittsgrößere Höhlung des Kragens 22, wobei die Federbeinchen 21 schließlich dann hakenartig den Stirnbereich, respektive das Stirnende 22′ des Kragens 22 übergreifen. Für den endlichen Übergriff können die Beinchen kurz in eine Strecklage überführt wer­den, welche Spreizstellung einfach durch Einführen eines Spreitzkernes von der Unterseite her erreicht wird.The axial support surface forms the free end 22 'of the collar 22 on which the free end 21' of the strut 21, which is angled outwards perpendicularly to the longitudinal center axis xx, is supported. A type of undercut claw can also be realized. The struts 21 are then transferred into the section running parallel to the longitudinal central axis xx in a bevel converging towards the center. The corresponding kink brings the resilient stock of elongation. Since the corresponding rebound length of the strut is accommodated within the collar 22, this also has the function of a spring chamber in addition to being a cable bridge for the pasty mass M. To assign the output valve V2 designed in this way, all that is required is to bundle the spring struts 21 so that they can be passed through the narrowed inlet opening 19 by pushing them into the larger-sized cavity of the collar 22, the spring struts 21 then finally hooking the front region or the front end 22 'of the collar 22 overlap. For the finite encroachment the legs can be briefly transferred to a stretched position, which spread position is simply achieved by inserting a spreading core from the underside.

Zur Verbindung der Betätigungshandhabe B mit dem Balg 5 weist dieser einen Außenkragen 23 auf, welcher den praktisch als Führungskragen fungierenden Kragen 22 dichtschließend reibungsschlüssig überfängt. Der Außenkragen 23 ragt mit zwei Dritteln seiner Länge in das Innere der Pumpenkammer 6 und mit etwa einem Drittel seiner Länge über die kuppelförmi­ge Wandung hinaus in Richtung der Unterseite der Betätigungs­handhabe B, an welcher Unterseite er sich abstützt.To connect the actuating handle B to the bellows 5, the latter has an outer collar 23, which overlaps the collar 22, which acts practically as a guide collar, in a friction-locking manner. The outer collar 23 protrudes with two thirds of its length into the interior of the pump chamber 6 and with about a third of its length beyond the dome-shaped wall in the direction of the underside of the actuating handle B, on which underside it is supported.

Das inverse Ende des Außenkragens 23 überragt das entspre­chende Ende des Kragens 22 leicht, mit anderen Worten, der Kragen 22 der Betätigungshandhabe B endet mit axialem Ab­stand zu dem unteren Rand des Außenkragens 23. Hierdurch entsteht rotationssymmetrisch eine Stufenecke, in der das hakenförmige Ende 21′ der Federbeinchen 21 abgestützt ein­liegt. Auf diese Weise wird auch eine radial nach auswärts gerichtete Abstützung der Federbeinchen gewonnen. Die Mantel­fläche des Kranges etwa überragende Vorstände werden beim Einstecken des Kragens 22 in die Höhlung des Außenkragen exakt lagedefiniert zurückgeschoben. Für alle Beinchen lie­gen so gleichberechtigte Federeingenschaften vor. Jedwedes Kippen des Ventiltellers 20 und damit zusammenhängende Fehl­schlüsse sind vermieden.The inverse end of the outer collar 23 projects slightly beyond the corresponding end of the collar 22, in other words, the collar 22 of the actuating handle B ends at an axial distance from the lower edge of the outer collar 23. This creates a step corner in a rotationally symmetrical manner, in which the hook-shaped end 21 ′ the strut 21 rests supported. In this way, a radially outward support of the strut is obtained. When the collar 22 is inserted into the hollow of the outer collar, the executive boards, which are somewhat superior, are pushed back in a precisely defined position. Equal spring properties are available for all legs. Any tilting of the valve plate 20 and associated incorrect conclusions are avoided.

Das Eingangsventil V1 ist in seinem Durchmesser im wesentli­chen dem Durchmesser des Außenkragen 23 angepaßt. Der Außen­kragen fluchtet praktisch mit dem Umriß der entsprechenden Ventilklappe 15. Der Abstand der Unterseite des Kragens zur Ventilklappe 15 entspricht etwa einem Drittel bis der Hälfte des Durchmessers des Eingangsventils V1. So liegt ein gedrun­gender Aufbau vor.The diameter of the inlet valve V1 is essentially adapted to the diameter of the outer collar 23. The outer collar is practically aligned with the outline of the corresponding valve flap 15. The distance from the underside of the collar to the valve flap 15 corresponds to approximately one third to half the diameter of the inlet valve V1. So there is a compact structure.

Zur Betätigung kann auf irgendeine Randzone der tellerförmi­gen Betätigungshandhabe B eine Kraft in Richtung des Pfeiles P ausgeübt werden. Extreme seitliche Verlagerungen sind unterbunden durch Anformung eines Stehkragens 24. Letzterer geht von der Oberseite der Decke 7 randbeabstandet aus. Er verläuft konzentrisch zur Längsmittelachse x-x und wird in Grundstellung teilüberlappend übergriffen durch den nach unten gezogenen, ebenfalls zylindrischen Rand 16 der Betäti­gungshandhabe B. Zwischen der Innenwandung dieses Randes 16 und der Mantelwand des Stehkragens 24 ist ein Ringspalt belassen, so daß Kippbewegungen der Betätigungshandhabe nicht zu einem Verklemmen führen. Den Betätigungsbegrenzungs­anschlag bildet der jenseits des Stehkragens 24 verbliebene Ringabschnitt der Decke 7 des Einsatzes 8.For actuation, a force in the direction of arrow P can be exerted on any edge zone of the plate-shaped actuation handle B. Extreme lateral displacements are prevented by forming a stand-up collar 24. The latter starts from the top of the ceiling 7 at a distance from the edge. It extends concentrically to the longitudinal central axis xx and is partially overlapped in the basic position by the downwardly drawn, also cylindrical rim 16 of the actuating handle B. Between the inner wall of this rim 16 and the jacket wall of the standing collar 24, an annular gap is left, so that tilting movements of the actuating handle are not permitted jamming. The actuation limiting stop is formed by the ring section of the cover 7 of the insert 8 that remains beyond the standing collar 24.

Die Betätigungshandhabe B ist überfangen von einer Schutzkap­pe 25, welche auf den deckelförmigen Einsatz 8 einfach aufge­steckt wird oder, wie die linksseitige Schnitthälfte der Figur 3 veranschaulicht, im Wege der Schraubverbindung zuge­ordnet wird. Der Gewindeeingriff trägt das Bezugszeichen 26.The actuating handle B is overlaid by a protective cap 25 which is simply pushed onto the cover-shaped insert 8 or, as the left-hand cut half of FIG. 3 illustrates, is assigned by way of the screw connection. The thread engagement bears the reference number 26.

Zur Sicherung des Einsatzes am Gehäuse 1 ist eine Rastverbin­dung 27 zwischen beiden Teilen gewählt. Den Einsteckbegren­zungsanschlag übernimmt ein der Mantelwand des topfförmigen Einsatzes 8 außenseitig angeformter Ringbund 28, welcher mit seiner unterseitigen Flanke gegen das korrespondierende Stirnende des Gehäuses 1 tritt und mit seiner oberseitigen Flanke den Aufsteckbegrenzungsanschlag für die Schutzkappe 25 bietet.To secure the insert on the housing 1, a snap connection 27 is selected between the two parts. The push-in limit stop is taken over by an annular collar 28 formed on the outside of the jacket wall of the pot-shaped insert 8, which strikes the corresponding front end of the housing 1 with its underside flank and offers the push-on stop for the protective cap 25 with its top flank.

In der Variante mit Gewindeausbildung 26 ist der dortige, oberhalb des Ringbundes 28 liegende Topfwandungsabschnitt nach innen versetzt, so daß eine durchgehend ebenengleiche Ausrichtung aller spenderbildenden Teile gewahrt ist.In the variant with thread formation 26, the pot wall section located there above the annular collar 28 is offset inwards, so that all dispenser-forming parts are aligned in the same plane throughout.

Die dem Pumpelement zugewandte Stirnseite des topfförmigen Kolbens 2 besitzt eine dem korrespondierenden Spenderkopf entsprechende Negativkonturierung, so daß nahezu eine rest­freie Ausgabe der pastösen Masse M erreicht wird.The end face of the cup-shaped piston 2 facing the pump element has a corresponding dispenser head Corresponding negative contouring, so that a residue-free output of the pasty mass M is achieved.

Die Funktion des Spenders ist wie folgt:The function of the donor is as follows:

Durch Druck auf die Betätigungshandhabe B in Richtung des Pfeiles P wird der Balg 5 unter Volumenverringerung der Pumpenkammer 6 zusammengedrückt. Der in der Pumpenkammer be­findliche Anteil an pastöser Masse tritt unter Öffnen des Ausgangsventils V2 aus der Austrittsöffnung 19 und legt sich auf der Randzone dieser Öffnung im Zentrum der muldenförmi­gen Ausstreiffläche 18 ab. Der mit der Pumpkammer 6 verbunde­ne Kragen 22 fungiert hier als Leitungsbrücke. Bei der besag­ten Betätigung bleibt das als Rückschlagventil gestaltete Eingangsventil V1 zufolge des Überdrucks in der Pumpkammer 6 geschlossen. Sobald der Überdruck nachläßt, ziehen die Feder­beinchen 21 den Ventilteller 20 in seine die Austrittsöff­nung 19 vollkommen ausfüllende Schließgrundstellung zurück. Unter Loslassen der Betätigungshandhabe B stellt sich der Balg 5 zufolge entsprechender Materialwahl wieder in seine Ausgangstellung zurück. Das führt zu Unterdruck in der Pump­kammer 6. Demzufolge hebt sich die Ventilklappe 15 um ihr seitliches Filmscharnier 16 schwenkend an. Über die diesbe­zügliche Ventilöffnung wird nun pastöse Masse in die Pumpkam­mer 6 nachgesaugt. Einhergehend hiermit verlagert sich der Kolben 2 über die Füllstandssäule um einen Schritt in Rich­tung des Kopfstückes K nach. Ein Einsaugen von Falschluft ist zufolge der Funktion des Ausgangsventiles V2 unterbun­den, auch jedwedes Eintrocknen der pastösen Masse.By pressing the actuating handle B in the direction of arrow P, the bellows 5 is compressed, reducing the volume of the pump chamber 6. The portion of pasty mass located in the pump chamber emerges from the outlet opening 19 when the outlet valve V2 is opened and is deposited on the edge zone of this opening in the center of the trough-shaped stripping surface 18. The collar 22 connected to the pump chamber 6 functions here as a line bridge. During said actuation, the input valve V1 designed as a check valve remains closed due to the excess pressure in the pump chamber 6. As soon as the excess pressure subsides, the spring struts 21 pull the valve disk 20 back into its basic closing position which completely fills the outlet opening 19. When the actuating handle B is released, the bellows 5 returns to its starting position according to the appropriate choice of material. This leads to negative pressure in the pump chamber 6. As a result, the valve flap 15 lifts pivoting about its lateral film hinge 16. Pasty mass is now sucked into the pump chamber 6 via the relevant valve opening. Along with this, the piston 2 is displaced by one step in the direction of the head piece K via the level column. According to the function of the outlet valve V2, sucking in of false air is prevented, and also any drying of the pasty mass.

Alle in der Beschreibung erwähnten und in der Zeichnung dargestellten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
