Definitions

  • the invention relates to dispensers for the portioned dispensing of liquid to pasty masses, with dispensing device arranged on the neck of a bottle or the like, which dispenser has a dispensing valve and an actuating head piece having a lateral dispensing opening, which protrudes in the apex region of a flexible pump chamber wall and, penetrating the pump chamber, is guided in a hub of the pump chamber floor.
  • a donor of this type is known from European patent application 0 035 588.
  • the hub guiding the actuating head piece has spokes which extend over the entire transverse width of the cylindrical dispenser housing.
  • the guided shaft of the actuating head piece is implemented as a tube which is closed on the housing bottom side. At a distance from the end of the tube there are openings for passage of the dispensed material into the interior of the tube, where it finally exits through the side-pointing dispensing opening.
  • the openings and the inner wall of the hub sealingly in the basic position have a valve function; they form the so-called dispensing valve. The opening of the same results when the output device is pushed down. The medium under pressure swells through the openings into the interior of the shaft.
  • the last actuation stroke is finally limited by a pressure plate which is provided in the forerunner described and which runs behind the fill level column and is blocked on one side. This is because the shaft end there runs towards it, and the open pump chamber floor leaves a relatively large remaining amount of the dispensed material unfit for dispensing.
  • the object of the invention is to design a generic dispenser in a technically simple, advantageous manner in such a way that a largely residue-free discharge of the filling material is achieved.
  • the storage room and pump room are clearly subdivided. There are no more application-neutral zones of the usual size.
  • the medium reaches the pump chamber directly through the hub. This eliminates the force-consuming rearrangement of the medium that occurs particularly with pasty contents; it is moved linearly through the pump zone.
  • the structural means are simple and functional. In this regard, the procedure is such that the hub wall of the closed pump chamber floor continues in the bottle into a pump inlet valve chamber, the actuating head piece is star-shaped on its length leading in the hub and the outer narrow edge of at least one star rib is clipped behind a stop bead on the upper edge of the Hub grips.
  • the pump chamber wall is designed as a truncated cone-shaped bellows. As a result of the folding there is an even reduction in volume; the flexible pump chamber wall cannot evade. With a relatively small actuation pressure area, the forces are distributed over the entire bellows body. Its base faces the bottle neck. A targeted delivery of the goods is achieved by means of a rotation lock between at least one star rib and the stop bead of the hub.
  • a favorable clip assignment is achieved in that the star ribs towards the bottle-side end taper to a point, ie her back is undercut like a notch valley. On the one hand, this leads to a spring deflection free space on the central shaft of the actuating head piece and, on the other hand, to a material saving that is again quite interesting today.
  • the star ribs start from a transverse wall of the actuating head piece, above which a pump discharge valve chamber extends. The latter leads to a mutual stabilization of the adjoining games.
  • the invention further proposes that the pressure surface of the actuating head piece is formed by a clipped-in wall which carries the spring of the dispensing valve on its underside.
  • the invention proposes that the bottom wall of the pump inlet valve chamber continues into a suction hose connector.
  • the suction hose known as a riser pipe can even be molded directly onto the nozzle, which further reduces the number of parts.
  • an air inlet opening is provided on the inside of the pump chamber bottom of the bottle in the side wall of the dispensing device, in front of which a valve seat surface extends on the outside, onto which the bottle-side end edge of the bellows is placed as a cantilevered lip which, in the case of air suction, escapes into the spacing annular space.

  • a corresponding anti-rotation lock is useful if, for example, taking into account a molded handle on the bottle body, a certain dispensing direction is provided for the discharge channel 23 of a beak-like mouthpiece that leads away laterally from the actuating head piece 16.

Description

Die Erfindung bezieht sich auf Spender zur portionierten Ausgabe flüssiger bis pastöser Massen, mit auf dem Hals einer Flasche oder dergleichen angeordneter Ausgabeeinrichtung, die ein Ausgabeventil und ein eine seitliche Ausgabeöffnung aufweisendes Betätigungskopf­stück besitzt, welches im Scheitelbereich einer flexiblen Pumpenraum­wand vorsteht und, den Pumpenraum durchsetzend, in einer Nabe des Pumpenraumbodens geführt ist.The invention relates to dispensers for the portioned dispensing of liquid to pasty masses, with dispensing device arranged on the neck of a bottle or the like, which dispenser has a dispensing valve and an actuating head piece having a lateral dispensing opening, which protrudes in the apex region of a flexible pump chamber wall and, penetrating the pump chamber, is guided in a hub of the pump chamber floor.

Ein Spender dieser Art ist durch die europäische Patentanmeldung 0 035 588 bekannt. Dort weist die das Betätigungskopfstück führende Nabe Speichen auf, die sich über die gesamte Querbreite des zylindri­schen Spendergehäuses erstrecken. Der geführte Schaft des Betäti­gungskopfstückes ist als gehäusebodenseitig verschlossenes Röhrchen realisiert. Im Abstand zum dortigen Röhrchenende befinden sich Öff­nungen zum Durchtritt des Ausgabegutes in das Röhrcheninnere, wo es schließlich über die seitlich weisende Ausgabeöffnung austritt. Die Öffnungen und diese in Grundstellung dichtend umschließende Nabeninnenwandung haben Ventilfunktion; sie bilden das sogenannte Ausgabeventil. Das Öffnen desselben ergibt sich beim Abwärtsdrücken der Ausgabeeinrichtung. Das dabei unter Druck tretende Medium quillt durch die Öffnungen in das Schaftinnere. Der letzte Betätigungs­hub wird endlich durch einen bei dem erläuterten Vorläufer vorgesehe­nen, über die Füllstandssäule nachlaufenden, einseitig gesperrten Druckboden begrenzt. Dies, da das dortige Schaftende ihm entgegen­läuft, und der offene Pumpenraumboden belassen eine relativ große Restmenge des Ausgabegutes unausbringbar.A donor of this type is known from European patent application 0 035 588. There the hub guiding the actuating head piece has spokes which extend over the entire transverse width of the cylindrical dispenser housing. The guided shaft of the actuating head piece is implemented as a tube which is closed on the housing bottom side. At a distance from the end of the tube there are openings for passage of the dispensed material into the interior of the tube, where it finally exits through the side-pointing dispensing opening. The openings and the inner wall of the hub sealingly in the basic position have a valve function; they form the so-called dispensing valve. The opening of the same results when the output device is pushed down. The medium under pressure swells through the openings into the interior of the shaft. The last actuation stroke is finally limited by a pressure plate which is provided in the forerunner described and which runs behind the fill level column and is blocked on one side. This is because the shaft end there runs towards it, and the open pump chamber floor leaves a relatively large remaining amount of the dispensed material unfit for dispensing.

Aufgabe der Erfindung ist es, einen gattungsgemäßen Spender in herstellungstechnisch einfacher, gebrauchsvorteilhafter Weise so auszu­bilden, daß eine weitestgehend restfreie Ausbringung des Füllgutes erreicht wird.The object of the invention is to design a generic dispenser in a technically simple, advantageous manner in such a way that a largely residue-free discharge of the filling material is achieved.

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 vorteilhafte Weiterbildungen des erfindungs­gemäßen Spenders.The subclaims are advantageous developments of the dispenser according to the invention.

Zufolge solcher Ausgestaltung ist ein gattungsgemäßer Spender erhöh­ten Gebrauchswerts geschaffen: Vorratsraum und Pumpraum sind klar unterteilt. Es verbleiben keine ausbringungsneutralen Zonen in der gewohnten Größenordnung mehr. Das Medium gelangt auf direktem Wege unmittelbar durch die Nabe hindurch in den Pumpenraum. So entfällt die vor allem bei pastösem Inhalt auftretende kraftzehrende Um­lagerung des Mediums; es wird linear durch die Pumpenzone bewegt. Die baulichen Mittel sind einfach und zweckmäßig. So ist diesbezüglich so vorgegangen, daß die Nabenwand des geschlossen ausgebildeten Pumpenraumbodens sich flascheneinwärts in eine Pumpeneingangsven­til-Kammer fortsetzt, das Betätigungskopfstück auf seiner sich in der Nabe führenden Länge sternförmig gestaltet ist und die äußere Schmal­kante mindestens einer Sternrippe klipsend hinter einen Anschlagwulst am oberen Rand der Nabe greift. Diese Maßnahmen sind zudem form­technisch günstiger, bringen einen verbesserten Dichtungsgrad und begünstigen auch die angestrebte bedienungsleichtere Ausbringung. Vor allem sind optimale Voraussetzungen für einen Saughub geschaf­fen. Weiter erweist es sich als vorteilhaft, daß die Pumpenraumwand als kegelstumpfförmiger Faltenbalg gestaltet ist. Zufolge der Faltung ergibt sich eine gleichmäßige Volumenverkleinerung; es kann nicht zu einem Ausweichen der flexiblen Pumpenraumwand kommen. Bei verhält­nismäßig kleiner Betätigungs-Druckfläche verteilen sich die Kräfte auf den gesamten Balgkörper. Dessen Basis ist dem Flaschenhals zu­gewandt. Eine gezielte Ausgabe des Gutes erreicht man durch eine Drehsicherung zwischen mindestens einer Sternrippe und dem An­schlagwulst der Nabe. Eine kräftegünstige Klipszuordnung wird da­durch erreicht, daß die Sternrippen zum flaschenseitigen Ende hin spitz zulaufen, d. h. ihr Rücken ist kerbtalartig hinterschnitten. Dies führt zum einen zu einem Federausweich-Freiraum am zentralen Schaft des Betätigungskopfstückes und zum anderen zu einer heute durchaus wieder interessanten Materialeinsparung. Formtechnisch vorteilhaft gehen die Sternrippen von einer Querwand des Betäti­gungskopfstückes aus, oberhalb welcher sich eine Pumpen-Ausgabeven­til-Kammer erstreckt. Letzteres führt zu einer gegenseitigen Stabili­sierung der aneinander anschließenden Partien. Weiter bringt die Erfindung in Vorschlag, daß daß die Druckfläche des Betätigungskopf­stückes von einer eingeklipsten Wand mitgebildet ist, die an ihrer Unterseite die Feder des Ausgabeventiles trägt. Hieraus ergibt sich eine Mehrfachfunktion: Bildung der Druckfläche, Deckel der dortigen Federkammer, Träger der Ausgabeventil-Feder. Eine separate Feder hat stets den Nachteil, daß sie bei der Montage dem Pumpenaggregat versehentlich nicht mit einverleibt wird. Schließlich bringt die Erfin­dung in Vorschlag, daß sich die Bodenwand der Pumpeneingangsven­til-Kammer in einen Saugschlauch-Anschlußstutzen fortsetzt. Der als Steigrohr bekannte Saugschlauch kann sogar dem Stutzen unmittelbar angeformt sein, wodurch sich die Teilezahl weiter reduziert. Endlich ist es noch von Vorteil, daß flascheninnenseitig des Pumpenraumbodens in der Seitenwand der Ausgabeeinrichtung eine Lufteinlaßöffnung vorgesehen ist, vor der sich außenseitig mit Abstand eine Ventilsitz­fläche erstreckt, auf welche der flaschenseitige Stirnrand des Falten­balges als freiragende, bei Lufteinsaugen in den Abstandsringraum ausweichende Lippe aufsetzt. Unter Berücksichtigung des gewählten rotationssymmetrischen Aufbaues der Pumpen-Ausgabeeinrichtung können mehrere Öffnungen winkelgleich verteilt vorgesehen sein.As a result of such a configuration, a generic dispenser of increased utility value is created: the storage room and pump room are clearly subdivided. There are no more application-neutral zones of the usual size. The medium reaches the pump chamber directly through the hub. This eliminates the force-consuming rearrangement of the medium that occurs particularly with pasty contents; it is moved linearly through the pump zone. The structural means are simple and functional. In this regard, the procedure is such that the hub wall of the closed pump chamber floor continues in the bottle into a pump inlet valve chamber, the actuating head piece is star-shaped on its length leading in the hub and the outer narrow edge of at least one star rib is clipped behind a stop bead on the upper edge of the Hub grips. These measures are also more favorable in terms of shape, bring an improved degree of sealing and also favor the desired ease of use. Above all, optimal conditions are created for a suction stroke. It also proves advantageous that the pump chamber wall is designed as a truncated cone-shaped bellows. As a result of the folding there is an even reduction in volume; the flexible pump chamber wall cannot evade. With a relatively small actuation pressure area, the forces are distributed over the entire bellows body. Its base faces the bottle neck. A targeted delivery of the goods is achieved by means of a rotation lock between at least one star rib and the stop bead of the hub. A favorable clip assignment is achieved in that the star ribs towards the bottle-side end taper to a point, ie her back is undercut like a notch valley. On the one hand, this leads to a spring deflection free space on the central shaft of the actuating head piece and, on the other hand, to a material saving that is again quite interesting today. In terms of shape, the star ribs start from a transverse wall of the actuating head piece, above which a pump discharge valve chamber extends. The latter leads to a mutual stabilization of the adjoining games. The invention further proposes that the pressure surface of the actuating head piece is formed by a clipped-in wall which carries the spring of the dispensing valve on its underside. This results in a multiple function: formation of the pressure surface, cover of the spring chamber there, support of the output valve spring. A separate spring always has the disadvantage that it is inadvertently not incorporated into the pump unit during assembly. Finally, the invention proposes that the bottom wall of the pump inlet valve chamber continues into a suction hose connector. The suction hose known as a riser pipe can even be molded directly onto the nozzle, which further reduces the number of parts. Finally, it is also advantageous that an air inlet opening is provided on the inside of the pump chamber bottom of the bottle in the side wall of the dispensing device, in front of which a valve seat surface extends on the outside, onto which the bottle-side end edge of the bellows is placed as a cantilevered lip which, in the case of air suction, escapes into the spacing annular space. Taking into account the selected rotationally symmetrical structure of the pump output device, a plurality of openings can be provided distributed at the same angle.

Die als Dosierpumpe gestaltete Ausgabeeinrichtung 1 sitzt auf dem Hals 2 einer Flasche 3. Die Befestigung geschieht im Wege der Schraubver­bindung. Der Hals 2 weist dazu das entsprechende Außengewinde 4 auf, in welches Innengewinde 5 eines schraubkappenartigen Grundkör­pers eingreift. Dessen zylindrische Kappenwandung 6 besitzt außen­seitig die Griffigkeit erhöhende Axialriefung 7.The dispensing device 1 designed as a metering pump sits on the neck 2 of a bottle 3. The fastening takes place by means of the screw connection. For this purpose, the neck 2 has the corresponding external thread 4, in which the internal thread 5 of a screw cap-like base body engages. Its cylindrical cap wall 6 has axial grooves 7 on the outside that increase its grip.

Die Decke des schraubkappenartigen Grundkörpers fungiert als Trenn­wand zwischen dem Vorratsraum 9 der Flasche 3 und dem darüberlie­genden Pumpenraum 10 der Ausgabeeinrichtung 1.The ceiling of the screw cap-like base body acts as a partition between the storage space 9 of the bottle 3 and the pump space 10 of the dispensing device 1 lying above it.

Der Boden 8 formt zentral liegend eine Nabe N. Es handelt sich um eine zylindrische, hülsenartige Anformung, welche den Pumpenraum­boden 8 sowohl in Richtung des Vorratsraumes 9 als auch in Richtung des Pumpenraumes 10 hin überragt. Sie wurzelt in einer flaschenhals­seitigen Einziehung 11 des Bodens 8. Zwischen besagter Einziehung 11 und der Mantelfläche der Nabe N verbleibt ein schmaler Ringraum 12. Vom Einziehungsgrund aus erstreckt sich die Nabe, soweit es sich um die den gleichen lichten Querschnitt aufweisende Zone handelt, in beiden Richtungen in axial gerichtet gleicher Länge. Dabei entspricht ein Längenabschnitt praktisch dem lichten Durchmesser der Einziehung 11.The bottom 8 forms a hub N lying in a central position. It is a cylindrical, sleeve-like projection which projects beyond the pump chamber floor 8 both in the direction of the storage chamber 9 and in the direction of the pump chamber 10. It is rooted in a bottle neck-side indentation 11 of the base 8. Between the said indentation 11 and the lateral surface of the hub N, a narrow annular space 12 remains. From the base of the indentation, the hub extends in both, insofar as it is the same cross-sectional area Directions in the same length axially directed. A length section practically corresponds to the clear diameter of the recess 11.

In der Erstreckungsebene des Flaschenhalses geht der Boden 8 zu­nächst in eine Ringwand 13 über, und zwar in Richtung des Hals-­Stirnrandes 2ʹ, um von dort unter Bildung einer auswärts weisenden horizontalen Ringstufe in die zylindrische Kappenwandung 6 überzu­gehen. Der entsprechende Wandungsversprung führt zu einer aufset­zenden Dichtringschulter 13ʹ.In the plane of extension of the bottle neck, the bottom 8 initially merges into an annular wall 13, specifically in the direction of the neck-front edge 2ʹ, from where it merges into the cylindrical cap wall 6 to form an outwardly pointing horizontal annular step. The corresponding wall jump leads to a sealing ring shoulder 13ʹ.

In entgegengesetzter Richtung setzt sich die Ringwand 13 in einen den Pumpenraumboden 8 nach oben hin etwas überragenden, leicht aus­wärts gestellten Kragen 15 fort. Auf letzteren ist das flaschenseitige Ende eines die flexible Pumpenraumwand bildenden Faltenbalges B aufgeklipst. Dessen anderes, nach oben weisendes Ende sitzt an einem Betätigungskopfstück 16 der Ausgabeeinrichtung 1. Es tritt in einen unterseitigen Ringraum 17 anschlagbegrenzt ein. Auch hier kann eine Klipsverbindung realisiert sein.In the opposite direction, the annular wall 13 continues into a collar 15 which slightly protrudes above the pump chamber base 8 and is slightly outward. The bottle-side end of a bellows B forming the flexible pump chamber wall is clipped onto the latter. Its other, upward-facing end is seated on an actuating head piece 16 of the dispensing device 1. It enters an annular space 17 on the underside with a limit stop. A clip connection can also be realized here.

Das Betätigungskopfstück 16 ist in der Nabe N axial anschlagbegrenzt geführt. Dazu setzt es sich unterseitig in einen im Querschnitt stern­förmigen, vorzugsweise kreuzförmigen Schaft 18 fort. Zur Auszugs­begrenzung greift die Schmalkante 19ʹ mindestens einer Sternrippe 19 klipsend hinter einen Anschlagwulst 20 innenseitig am oberen Rand der Nabe N. Die mit dem Anschlagwulst 20 zusammenwirkende schaftseitige Anschlagschulter 21 ergibt sich aufgrund einer radialen Verbreiterung der in Grundstellung unmittelbar unterhalb der Anschlagwulst 20 anschließenden Zone der Schmalkante 19ʹ. Beim Ausführungsbeispiel sind sämtliche Schmalkanten 19ʹ klipstechnisch ausgerüstet.The actuating head piece 16 is guided in the hub N in an axially limited manner. For this purpose, it continues on the underside in a shank 18 which is star-shaped in cross section, preferably cruciform. To limit the extension, the narrow edge 19ʹ of at least one star rib 19 clips behind an abutment bead 20 on the inside at the upper edge of the hub N. The abutment shoulder 21 which cooperates with the abutment bead 20 results from a radial widening of the zone of the narrow edge which adjoins in the basic position immediately below the abutment bead 20 19ʹ. In the embodiment, all narrow edges 19ʹ are equipped with clips.

Wie Fig. 3 entnehmbar, ist die dort rechtsseitige Sternrippe 19 noch im Querschnittsbereich des Anschlagwulstes 20 auf eine größere Abstands­breite der Sternrippe 19 gebracht, der dort liegende Bereich der Nabe N jedoch aufgeschnitten, und zwar bis auf den Grund der Einziehung 11, so daß ein axial gerichteter, von oben her offener Längsschlitz 22 vorliegt, in den der radial nach auswärts verbreiterte Abschnitt 19ʹʹ der dortigen Sternrippe 19 hineinragt. Dies führt zu einer Drehsiche­rung zwischen dem Betätigungskopfstück 16 und der Nabe N. Eine entsprechende Drehsicherung ist von Nutzen, wenn bspw. unter Be­rücksichtigung einer dem Flaschenkörper angeformten Griffhandhabe eine bestimmte Ausgaberichtung für den vom Betätigungskopfstück 16 seitlich abführenden Ausgabekanal 23 eines schnabelartigen Mund­stückes vorgesehen ist. Dessen Mundstücköffnung ist mit 24 bezeich­net. Sie liegt außerhalb des maximalen Querschnitts der Flasche und erlaubt so eine gezielte Applikation des Inhaltes.As can be seen in FIG. 3, the star rib 19 on the right-hand side there is still brought to a larger spacing width of the star rib 19 in the cross-sectional area of the stop bead 20, but the area of the hub N lying there is cut open, to the bottom of the neck 11, so that a axially directed, from above open longitudinal slot 22 is present, in which the radially outwardly widened section 19ʹʹ the star rib 19 protrudes there. This leads to an anti-rotation lock between the actuating head piece 16 and the hub N. A corresponding anti-rotation lock is useful if, for example, taking into account a molded handle on the bottle body, a certain dispensing direction is provided for the discharge channel 23 of a beak-like mouthpiece that leads away laterally from the actuating head piece 16. Its mouthpiece opening is designated by 24. It lies outside the maximum cross-section of the bottle and thus allows the contents to be applied in a targeted manner.

Die Sternrippen 19 laufen zum flaschenseitigen Ende hin spitz zu, d. h. sie sind vom eigentlichen zentralen Kreuzkern des Schaftes 18 freigeschnitten. Hierdurch erhöht sich die Federfähigkeit; die Stern­rippen weichen federnd radial einwärts gerichtet aus. Die keilförmi­gen, sich nach oben hin verjüngenden Freischnittschlitze 25 überragen den oberen Rand der Nabe. Der Schaftkern hingegen überragt das untere Ende der Sternrippen 19. Die Außenkanten der Sternrippen 19 sind überdies stirnseitig gefast, so daß bei der Montage der Anschlag­wulst 20 leichter überlaufen werden kann. Das Abziehen des Schaftes von der Nabe ist dagegen auch nur unter Aufbringung höherer Ab­zugskräfte möglich. Die Zuordnung kann jedoch auch irreversibel sein.The star ribs 19 taper towards the bottle-side end, i. H. they are cut free from the actual central cross core of the shaft 18. This increases the resilience; the star ribs yield resiliently radially inwards. The wedge-shaped cut-out slots 25 tapering upward project beyond the upper edge of the hub. The shaft core, on the other hand, projects beyond the lower end of the star ribs 19. The outer edges of the star ribs 19 are also chamfered on the end face, so that the stop bead 20 can be overrun more easily during assembly. In contrast, the shaft can only be pulled off the hub by applying higher pulling forces. However, the assignment can also be irreversible.

Oberhalb des Schaftes 18 bildet das Betätigungskopfstück 16 eine Kammer 26 aus. Letztere dient zur Unterbringung eines Pumpen-Aus­gabeventils V 2. Dessen Ventilsitzfläche 27 befindet sich in einer Querwand 28, von welcher unterseitig die Sternrippen 19 ausgehen. Der Ventilteller 14 weist Kalottenform auf; sein nach oben gerichteter Schaft ist kreuzprofiliert. Die Schaftlängswände führen sich an der Wand der Kammer 26.Above the shaft 18, the actuating head piece 16 forms a chamber 26. The latter serves to accommodate a pump dispensing valve V 2. Its valve seat surface 27 is located in a transverse wall 28, from which the star ribs 19 extend on the underside. The valve disk 14 has a spherical shape; its shaft pointing upwards is cross-profiled. The longitudinal walls of the shaft lead to the wall of the chamber 26.

Die Ventilöffnung 29 reicht bis in den Pumpenbereich des kreuzprofi­lierten Schaftes 18. Der Bohrungsdurchmesser ist größer als die Dicke der Sternrippen 19 beträgt, wodurch sich eine gute Fensterung ergibt.The valve opening 29 extends into the pump area of the cross-profiled shaft 18. The bore diameter is larger than that Thickness of the star ribs is 19, which results in good fenestration.

Das Pumpen-Ausgabeventil V 2 steht unter Federbelastung. Die Feder 30 ist als Ringkörper realisiert und der Unterseite einer die Kammer 26 verschließenden Wand 31 angeformt. Letztere ist deckelseitig einge­klipst. Ihre Oberseite schließt im wesentlichen ebenengleich mit der des Betätigungsstückes 16 ab, bildet also anteilig die Betätigungsfläche 16ʹ.The pump output valve V 2 is under spring load. The spring 30 is realized as an annular body and is molded onto the underside of a wall 31 closing the chamber 26. The latter is clipped in on the cover side. Its top closes substantially at the same level as that of the actuating piece 16, thus forming a proportion of the actuating surface 16ʹ.

Der Ausgabekanal 23 mündet seitlich in die vom Medium durchlaufene Kammer 26.The discharge channel 23 opens laterally into the chamber 26 through which the medium flows.

Das flascheneinwärts gerichtete Ende der Ausgabeeinrichtung 1 formt einen Anschlußstutzen 32 für einen bis zum Boden 3ʹ der Flasche rei­chenden Ansaugschlauch 33. Dessen bodenseitige Mündung ist so gestellt oder geschnitten, daß die Flaschenwandung sein Ende nicht verschließen kann. Statt den auch als Steigrohr zu bezeichnenden Ansaugschlauch 33 über einen Stutzen dem dortigen Endabschnitt der Nabe N stecktechnisch zuzuordnen, kann der Ansaugschlauch 33 auch gleich mitangeformt sein.The bottle-inward end of the dispensing device 1 forms a connection piece 32 for a suction hose 33 reaching to the bottom 3ʹ of the bottle. Its mouth on the bottom is set or cut so that the bottle wall cannot close its end. Instead of assigning the suction hose 33, which can also be referred to as a riser pipe, via a connecting piece to the end section of the hub N there, the suction hose 33 can also be molded at the same time.

Oberhalb der Zuordnungsstelle formt die Nabe in einem querschnitts­reduzierten Endabschnitt 34 eine Kammer 35 für ein Pumpen-Eingangs­ventil V 1. Letzteres ist gleichen Aufbaues wie das in der Kammer 26 befindliche.Above the assignment point, the hub forms a chamber 35 for a pump inlet valve V 1 in a reduced-section end section 34. The latter is of the same construction as that in the chamber 26.

Die Ventilsitzfläche 36 liegt ebenfalls in einer durch Querschnittsredu­zierung gebildeten querwandartigen Schulterzone der dortigen Boden­wand 37. Die Ventilöffnung 38 fluchtet mit dem lichten Durchmesser des Ansaugschlauches 33.The valve seat surface 36 also lies in a transverse wall-like shoulder zone of the bottom wall 37 formed there by a reduction in cross-section. The valve opening 38 is aligned with the inside diameter of the suction hose 33.

Damit das Pumpen-Eingangsventil V 1 nicht auch der Kammer 35 in die nach oben anschließende, im Querschnitt größer gehaltene Nabenkam­mer rutschen kann, befindet sich im Übergangsbereich eine den Kam­merquerschnitt des Pumpen-Eingangventils V 1 etwas verkleinernde Ringschulter 39.So that the pump inlet valve V 1 cannot also slide into the chamber 35 into the upstream hub chamber with a larger cross section, there is an annular shoulder 39 in the transition area that somewhat reduces the chamber cross section of the pump inlet valve V 1.

Um den ausgebrachten Volumenanteil des Mediums durch Außenluft ausgleichen zu können, weist die zylindrische Ringwand 13 des schraubkappenartigen Grundkörpers unterhalb des Pumpenraumbodens 8, also auf der dem Vorratsraum 9 zugewandten Seite mindestens eine Lufteinlaßöffnung 40 auf. Es sind derer beim Ausführungsbeispiel jedoch drei vorgesehen. Diese liegen in gleichmäßiger Winkelvertei­lung. Vor den Lufteinlaßöffnungen 40 erstreckt sich außenseitig mit Abstand dazu eine Ventilsitzfläche 41. Diese liegt innerhalb einer Ringrinne 42 und ist als auswärts liegende Rinnenflanke ist schräg gestellt, d. h. sie steigt kontinuierlich nach oben hin an. Auf ihr liegt unter leichter Vorspannung der äußere flaschenseitige Stirnrand 43 des Faltenbalges B. Diese nach unten weisende Randzone des flexiblen Faltenbalges weicht bei Lufteinsaugen in den entsprechend breit bemessenen Abstandsringraum 44 der Ringrinne 42 aus. Der Rand ist als deutlich querschnittsreduzierte und damit flexibler ausfal­lende Lippe L realisiert.In order to be able to compensate for the volume fraction of the medium applied by outside air, the cylindrical ring wall 13 of the screw cap-like base body has at least one air inlet opening 40 below the pump chamber floor 8, that is to say on the side facing the storage chamber 9. However, three are provided in the exemplary embodiment. These lie in an even angular distribution. In front of the air inlet openings 40, a valve seat surface 41 extends on the outside at a distance therefrom. This lies within an annular groove 42 and is inclined as an outer groove flank, ie. H. it rises continuously upwards. The outer bottle-side end edge 43 of the bellows B lies on it under slight prestress. This downward-facing edge zone of the flexible bellows gives way to the correspondingly wide spaced annular space 44 of the annular groove 42 when air is sucked in. The edge is realized as a lip L that is significantly reduced in cross-section and thus more flexible.

Der in eine Ringnut des Kragens 15 eingeklipste Ringvorsprung des unteren Balgrandes ist querschnittsdicker als der übrige die Pumpen­raumwand bildende, kegelstumpfförmig gestaltete Balgkörper. Wie er­sichtlich, hebt die den Stirnrand des Kragens 15 überlagernde Endfalte 45ʹ der Balgfalten 45 in Grundstellung gemäß Fig. 3 ab. In Betäti­gungsstellung, in der sich die Balgfalten 45 berührend gegeneinander­legen (knöchern) bewirkt diese Schwenkverlagerung ein Kippen des unteren Balgrandes mit der Konsequenz einer erhöhten Andruckkraft der Lippe L an der Ventilsitzfläche 41.The annular projection of the lower bellows edge clipped into an annular groove of the collar 15 is thicker in cross-section than the rest of the bellows-shaped bellows body which forms the pump chamber wall. As can be seen, the end fold 45 'of the bellows folds 45 overlying the end edge of the collar 15 lifts off in the basic position according to FIG. 3. In the actuating position, in which the bellows folds 45 touch each other (bony), this pivoting displacement causes the lower edge of the bellows to tilt, with the consequence of an increased pressing force of the lip L on the valve seat surface 41.

Die Funktion ist wie folgt: Durch Ausübung einer Kraft in Richtung des Pfeiles P auf die Betätigungsfläche 16ʹ wird das Volumen der Pumpenkammer 10 verkleinert. Das in ihr aufgrund vorheriger Betäti­gungen vorhandene, dosierte Ausgabegut tritt über die Ventilöffnung 29 unter Anheben des Ausgabeventiles V 2 durch die Kammer 26 hin­durch zur Ausgabeöffnung 24. Der hierbei im Pumpenraum 10 herr­schende Überdruck bewirkt andererseits das Verschließen des Pum­pen-Eingangventils V 1, so daß das im Nabengrund/Pumpenraum be­findliche Medium nicht über den Ansaugschlauch 33 zurück in den Vorratsraum 9 gedrängt werden kann bzw. zurückfließt.The function is as follows: by exerting a force in the direction of arrow P on the actuating surface 16ʹ, the volume of the pump chamber 10 is reduced. The dosed output material present in it due to previous actuations passes through the valve opening 29 while lifting the dispensing valve V 2 through the chamber 26 to the dispensing opening 24. The overpressure prevailing in the pump chamber 10 on the other hand causes the pump input valve V 1 to be closed, so that the medium in the hub base / pump chamber cannot be forced back into the reservoir 9 or flows back via the suction hose 33.

Läßt man nach Ausgabe der portionierten Menge nun das Betätigungs­kopfstück 16 der Ausgabeeinrichtung 1 wieder los, so entsteht im Pumpenraum 10 eine Unterdrucksituation, welche das Pumpen-Ein­gangsventil V 1 öffnet und das Pumpen-Ausgabeventil V 2 verschließt. Über das geöffnete Eingangsventil V 1 wird Medium in den Pumpenraum nachgesogen, bis der Schaft 18 in seine anschlagbegrenzte Endstellung tritt. Die nächste Ausgabe an Medium kann eingeleitet werden.If the operating head piece 16 of the dispensing device 1 is now released after the portioned quantity has been dispensed, a vacuum situation arises in the pump chamber 10, which opens the pump inlet valve V 1 and closes the pump dispensing valve V 2. Medium is drawn into the pump chamber via the opened inlet valve V 1 until the shaft 18 reaches its stop-limited end position. The next issue of medium can be initiated.

Der Faltenbalg B fungiert als die Grundstellungen stets wieder herbei­führende Rückholfeder.The bellows B acts as the return spring which always brings about the basic positions.

Mit dem Hochfahren des Betätigungskopfstücks 16 hebt die Lippe L von ihrer Ventilsitzfläche 41 ab, so daß entnommenes Medium durch über die Lufteinlaßöffnung 40 in den Vorratsraum 9 gelangende Luft ausge­glichen wird. Die federnde Anlage der Lippe verhindert bei Umfallen des Behälters überdies den Austritt von Medium.When the actuating head piece 16 is raised, the lip L lifts off its valve seat surface 41, so that the medium removed is compensated for by air entering the storage space 9 via the air inlet opening 40. The resilient contact of the lip also prevents the medium from escaping if the container falls over.

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.
