Abstract

The present invention relates to a dispenser for pasty compositions having a bellows on the top, a piston which travels in the direction towards the nozzle, and a rod which connects the bellows to the piston in such a manner that there is an idle stroke between piston rod and bellows so that a certain quantity of the content of the container withdraws into the nozzle channel upon release of the bellows.

Description

Die Erfindung bezieht sich auf einen Spender für pastöse Massen, mit im Spendergehäuse verschieblich angeordnetem, bei der Spenderentleerung in Richtung der Mundstücköffnung wandernden, in Gegenrichtung von einem Gesperre blockierten Kolben, einer Drucktasten-Betätigungsfläche, die an einem zusammendrückbaren Kopfstück des Spendergehäuses vorgesehen ist, und einer den Kolben durchsetzenden, mit dem Kopfstück gekuppelten Stange, die unter Zwischenschaltung eines entgegengesetzt zum ersten Gesperre arbeitenden zweiten Gesperres kraftschlüssig mit dem Kolben gekuppelt ist.The invention relates to a dispenser for pasty masses, with a displaceably arranged in the dispenser housing, migrating in the direction of the mouthpiece opening when the dispenser is emptied, piston blocked in the opposite direction by a locking mechanism, a pushbutton actuation surface which is provided on a compressible headpiece of the dispenser housing, and a rod passing through the piston and coupled to the head piece, which is non-positively coupled to the piston with the interposition of a second locking mechanism working counter to the first locking mechanism.

Ein Spender dieser Art ist durch die US-A-3255935 bekannt. Dort besteht das zusammendrückbare Kopfstück aus einer dem Spendergehäuse zugeordneten, flachkuppelartig gewölbten Kappe aus elastischem Material. Letztere weist eine radial gerichtete Mundstücköffnung auf. Das Mundstück besteht aus einem röhrchenartigen Fortsatz der Kappe. Je nach Betätigungsrichtung kann sich das Röhrchen in bezug auf die Zielrichtung unerwünscht verlagern, so dass der Auftrag von bspw. Zahncreme auf die recht kleine Aufnahmefläche der Bürste doch sehr erschwert ist. Ausserdem weisen Spender dieser Art den Nachteil auf, dass es bei beendeter Betätigung noch zu einem Nachlaufen des Füllinhaltes aus der Mundstücköffnung kommt. Das kann zu einem Antrocknen der ausgabeseitigen Endzone der pastösen Masse führen. Bei Lösen des Stopfens schiesst dann plötzlich eine unkontrollierte Menge aus, dies wiederum unter erschwerter Beibehaltung derZielrichtung.A dispenser of this type is known from US-A-3255935. There, the compressible head piece consists of a flat dome-like cap of elastic material assigned to the dispenser housing. The latter has a radially directed mouthpiece opening. The mouthpiece consists of a tube-like extension of the cap. Depending on the direction of actuation, the tube can shift undesirably with respect to the target direction, so that the application of toothpaste, for example, to the rather small receiving surface of the brush is very difficult. In addition, dispensers of this type have the disadvantage that when the actuation is complete, the contents of the filling continue to run out of the mouthpiece opening. This can lead to the end zone of the pasty mass drying out. When the stopper is loosened, an uncontrolled amount suddenly shoots out, again while keeping the target direction difficult.

Aufgabe der Erfindung ist es, einen gattungsgemässen Spender in herstellungstechnisch einfacherer, gebrauchsvorteilhafterer Bauform so auszubilden, dass kein Nachlaufen bei üblichen Ausgabemengen mehr auftritt, also der erwähnte, dem schnellen Austrocknen ausgesetzte Überstand vor der Mundstücköffnung vermieden wird.The object of the invention is to design a generic dispenser in a production-technically simpler, more advantageous design in such a way that there is no more run-on with the usual dispensing quantities, that is to say the above-mentioned excess drying out before the mouthpiece opening is avoided.

Gelöst ist diese Aufgabe durch die im Änspruch 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 geschaffen, bei dem der wesentliche Gebrauchsvorteil vorliegt, dass sich nach beendeter Betätigung vor der Mundstücköffnung kein Überstand mehr bildet; durch die erfindungsgemässe Ausgestaltung wird vielmehr die ausgabeseitig liegende pastöse Restmasse wieder in die Mundstücköffnung zurückgezogen. Sie steht dadurch in direkter Verbindung mit dem Füllinhalt und kann folglich durch den gegebenen Feuchteanschluss nicht austrocknen. Verantwortlich hierfür ist die Berücksichtigung eines Freiganges in der Spendermechanik. Der entsprechende Freigang bringt einen kürzeren Hubweg des über die Stange nachgezogenen, die pastöse Masse nachschiebenden Kolbens gegenüber einem relativ grösseren Betätigungshub des balgartig zusammendrückbaren Kopfstückes, was zu dem den Überstand einziehenden Saugeffekt führt. Auch ein zufälliges Berühren der Drucktasten-Betätigungsfläche um das Mass des Freiganges bringt keine Abgabe. Allenfalls wird eine Masse um die Einsaugtiefe wieder vorgeschoben, wonach sie aber bei Rückstellung des balgartigen Kopfstückes sofort wieder eingesogen wird. Eine funktionsgerechte Ausgabe ergibt sich folglich erst bei dem eigentlichen Arbeitshub, d.h. bei Verlagerung der Stange. Deren Zurückziehen durch die Rückstellkraft des Kopfstückes bringt das Anheben des Vorratsniveaus. Dieser Funktion zeitlich vorgelagert tritt aufgrund des Freiganges stets der Einsaugeffekt auf. Die gegenläufig wirkenden beiden Gesperre der Spendermechanik gewährleisten die angestrebte funktionssichere Handhabung des Spenders. Die baulichen Mittel sind einfach und montagegünstig gestaltet: So weist die Stange an ihrem kopfseitigen Ende einen verjüngten Abschnitt mit verbreitertem Endstück auf, welches in einer unterhalb der Drucktasten-Betätigungsfläche angeordneten Kammer des Kopfstückes liegt. Es ist dort vom Kammerboden untergriffen und weist zur Realisierung des Freiganges eine geringere Höhe auf als die der Kammer beträgt. Eine einfache Zuordnung besteht darin, dass das Endstück durch die Öffnung des Kammerbodens hindurch einklipsbar ist. Zufolge der Tatsache, dass die Stange zum Nachfördern des Vorrats in den Ausgabebereich des Spenders auf Zug beansprucht ist, kann sie im Querschnitt dünn gehalten sein, was wiederum den Füllraum vergrössert.As a result of such an embodiment, a dispenser of the generic type is created, in which there is the essential advantage in use that after actuation has ended, no more protrusion forms in front of the mouthpiece opening; rather, the inventive pasty residual mass is drawn back into the mouthpiece opening by the configuration according to the invention. As a result, it is directly connected to the contents and cannot dry out due to the moisture connection. This is due to the consideration of a free passage in the dispenser mechanics. The corresponding clearance brings a shorter stroke of the piston, which is pulled over the rod and pushes the pasty mass, compared to a relatively larger actuation stroke of the bellows-compressible head piece, which leads to the suction effect which draws in the excess. Accidental touching of the pushbutton actuation area by the measure of the clearance does not result in a delivery. At most, a mass is advanced by the suction depth, after which it is immediately sucked in again when the bellows-like head piece is reset. Functional output therefore only results from the actual working stroke, i.e. when moving the rod. Pulling them back due to the restoring force of the head piece brings the supply level up. This function always precedes the suction effect due to the clearance. The opposing two locking mechanisms of the dispenser mechanics ensure the intended safe and reliable handling of the dispenser. The structural means are simple and easy to assemble: the rod has a tapered section with a widened end piece at its head end, which lies in a chamber of the head piece arranged below the pushbutton actuation area. It is underneath the chamber floor and has a lower height than the chamber for realizing the access. A simple assignment is that the end piece can be clipped in through the opening of the chamber bottom. As a result of the fact that the bar for pulling the supply into the dispensing area of the dispenser is subjected to tension, it can be kept thin in cross section, which in turn increases the filling space.

Weitere Vorteile und Einzelheiten des Gegenstandes der Erfindung sind nachstehend anhand eines zeichnerisch veranschaulichten Ausführungsbeispieles näher erläutert. Es zeigt:

  • Fig. 2 den Schnitt gemäss Linie 11-11 in Fig. 1.
Further advantages and details of the subject matter of the invention are explained in more detail below with reference to an exemplary embodiment illustrated in the drawings. It shows:
  • Fig. 1 the dispenser designed according to the invention in vertical section and
  • 2 shows the section along line 11-11 in Fig. 1st

Das lang zylindrisch ausgebildete Gehäuse 1 des Spenders enthält einen Kolben 2. Dessen Randlippen 2' führen sich an der zylindrischen Gehäuseinnenwandung 1'. Das Gehäuse 1 ist unten offen.The long, cylindrical housing 1 of the dispenser contains a piston 2. Its edge lips 2 'lead to the cylindrical housing inner wall 1'. The housing 1 is open at the bottom.

Der Kolben 2 ist ausschliesslich in Entleerungsrichtung (Pfeil x) verlagerbar. Er trägt auf seiner dem aufstellseitigen Gehäuseende zugewandten Breitfläche ein erstes Gesperre G1. Es handelt sich um einen sogenannten Klemmodul 3 in Form eines radial ausgerichtete Zacken 3' aufweisenden Sternes aus Federstahl. Sein die Zackenenden umschreibender Durchmesser ist etwas grösser als der lichte Durchmesser des Gehäuses, wodurch sich die Zackenenden als schräg stehende Stützfüsse an der Gehäuseinnenwandung 1' entgegen der Richtung des Pfeiles x sperrend verhaken.The piston 2 can only be displaced in the direction of emptying (arrow x). It carries a first locking mechanism G1 on its broad surface facing the housing end on the installation side. It is a so-called clamping module 3 in the form of a radially oriented tooth 3 'having a star made of spring steel. Its diameter circumscribing the serrated ends is somewhat larger than the inside diameter of the housing, as a result of which the serrated ends hook on the housing inner wall 1 'in the opposite direction of the arrow x as inclined support feet.

Im Zentrum bildet dieser Klemmodul 3 ein zweites Gesperre G2 aus. Mit letzterem wirkt eine den Kolben 2 zentral durchsetzende Stange 4 zusammen. Die einwärts gerichteten Zacken 3" greifen an der von einem glatten Stab gebildeten Stange 4 an. In die Ebene projiziert, ist die von den Zacken 3" belassene Durchtrittsöffnung kleiner als der Durchmesser der Stange 4 beträgt. Das bodenseitige Ende der Stange 4 ist angespitzt. Die folglich auch hier schräg stehenden Stützfüsse lassen eine behinderungsfreie Durchsteckbewegung der Stange 4 entgegen der Pfeilrichtung x zu. Eine in Richtung des Pfeiles x erfolgende Stangenbewegung führt dagegen aufgrund der kraftschlüssigen Kupplung zu einer Mitnahme des Kolbens.2.This clamping module 3 forms a second locking mechanism G2 in the center. A rod 4, which penetrates the piston 2 centrally, interacts with the latter. The inward points 3 " attack on the rod 4 formed by a smooth rod. Projected into the plane, the passage opening left by the prongs 3 ″ is smaller than the diameter of the rod 4. The bottom end of the rod 4 is pointed A rod movement in the direction of arrow x, on the other hand, leads to the piston being driven due to the frictional coupling. 2.

Zu dieser Mitnahme bildet das Gehäuse 1 an der dem Standsockel 5 desselben gegenüberliegenden Seite eine Betätigungshandhabe aus. Es handelt sich um ein balgartig in Richtung des Kolbens 2 zusammendrückbares, sich wieder in seine Grundstellung aufrichtendes Kopfstück 6. Letzteres ist auf den etwas verschmälerten Hals 7 des Gehäuses 1 aufgesteckt. Über einen Ring-Nuteingriff im Zusammenwirken mit der Rückstellkraft des das Kopfstück 6 bildenden Materiales liegt eine gebrauchsstabile Befestigung vor.For this entrainment, the housing 1 forms an actuating handle on the side opposite the base 5 of the same. It is a headpiece 6 which can be compressed like a bellows in the direction of the piston 2 and rises again into its basic position. The latter is plugged onto the somewhat narrower neck 7 of the housing 1. Via a ring groove engagement in cooperation with the restoring force of the material forming the head piece 6 there is a use-stable attachment.

Das Kopfstück 6 formt eine querschnittsverringerte, kanalartige Spender-Mundstücköffnung 8. Diese ist schnabelförmig gestaltet. Ihr vorzugsweise kreisrunder Öffnungsmund liegt in Nähe der verlängerten Erstreckungsrichtung der Gehäusewandung und kann, für die Zeiten der Lagerhaltung, mit Hilfe eines Stopfes 9 verschlossen sein.The head piece 6 forms a cross-section-reduced, channel-like dispenser mouthpiece opening 8. This is beak-shaped. Its preferably circular opening mouth lies in the vicinity of the extended direction of extension of the housing wall and can be closed with the aid of a plug 9 for storage times.

Das Kopfstück 6 bildet des weiteren im Rücken des die Mundstücksöffnung umschreibenden, schnabelartigen Fortsatzes in seiner Deckenpartie eine Drucktasten-Betätigungsfläche 10 aus. Letztere reicht bis kurz vor die gegenüberliegende, gedanklich verlängerte Gehäuse-Wandungsebene und steigt nach aussen schräg an.The head piece 6 also forms a pushbutton actuating surface 10 in the back of the beak-like extension circumscribing the mouthpiece opening. The latter extends to just before the opposite, mentally extended housing wall level and rises outwards at an angle.

Unterhalb dieser Drucktasten-Betätigungsfläche 10 ist die das ganze Gehäuse 1 in der Längsmittelachse z-z durchsetzende Stange 4 mit dem Kopfstück 6 verbunden. Dem Kopfstück 6 ist dazu unterhalb dieser Drucktasten-Betätigungsfläche 10 gehäuseeinwärtsgerichtet eine Kammer 11 angeformt. Ihr Boden 12 lässt eine Öffnung 13. Durch letztere hindurch ist das pilzkopfartig verbreiterte Endstück 4' der Stange 4 eingesteckt. Die Zuordnung ist als Klipsverbindung realisiert, d.h. das verbreiterte Endstück 4' wird vom Kammerboden 12 untergriffen. Dazu bildet die Stange 4 an ihrem kopfstückseitigen Ende einen verjüngten Abschnitt 4" aus. Dies hat den Vorteil, dass für die Bildung des Endstückes 4' von einem durchgehenden Stangenquerschnitt ausgegangen werden kann.Below this pushbutton actuation surface 10, the rod 4 passing through the entire housing 1 in the longitudinal central axis z-z is connected to the head piece 6. For this purpose, the head piece 6 is formed below this pushbutton actuation surface 10 in the direction of the housing in the direction of a chamber 11. Its bottom 12 leaves an opening 13 through which the mushroom-head widened end piece 4 'of the rod 4 is inserted. The assignment is realized as a clip connection, i.e. the widened end piece 4 'is gripped by the chamber bottom 12. For this purpose, the rod 4 forms a tapered section 4 ″ at its end on the head piece side. This has the advantage that a continuous rod cross section can be assumed for the formation of the end piece 4 ′.

Die Öffnung 13 verbreitert sich kolbenseitig trichterförmig, wodurch trotz Querschnittsreduzierung im Klipsbereich eine sichere Fesselung von Stange 4 und Kopfstück 6 aneinander gegeben ist.The opening 13 widens on the piston side in a funnel shape, so that despite the reduction in cross-section in the clip area, the rod 4 and the head piece 6 are securely bonded to one another.

Die Zuordnung der Stange 4 am Kopfstück geschieht unter Berücksichtigung eines Freiganges γThe assignment of the rod 4 on the head piece is done taking into account a clearance γ

Hierzu besitzt das Endstück 4' eine geringere Höhe h als die in Stangenverlagerungs-Richtung liegende Höhe H der Kammer 11 beträgt. Dies führt zu einem dem eigentlichen Betätigungshub der Stange 4 vorgeschalteten Leerhub.For this purpose, the end piece 4 'has a lower height h than the height H of the chamber 11 lying in the direction of rod displacement. This leads to an idle stroke upstream of the actual actuation stroke of the rod 4.

Die Funktionsweise ist wie folgt: Die nach Entfernen des Stopfens 9 gegebene Bereitschaftsstellung führt bei dem balgartigen Zusammendrücken des praktisch domförmigen Kopfstückes 6 zu einem Verdrängen des im Kopfstück vorhandenen Anteiles der pastösen Masse M, und zwar unter Ausbringen der üblichen Ausgabemenge. Dies ist aber nur der Fall, wenn die Stange 4 nach Durchlaufen dieses Leerhubs (Freigang y) auch um einen sogenannten Arbeitshub entgegen der Richtung des Pfeiles x, also in Bodenrichtung verlagert wird. Aufgrund der nach Loslassen des Kopfstückes eintretenden Rückstellung desselben wird die ausgegebene Menge durch Heben des Kolbens 2 wieder ergänzt. Da sein Anheben unter, wenn auch geringer Zeitverzögerung erfolgt, und das im Kopfstück entstehende Vakuum eine Saugkraft erzeugt, wird der über die Mundstücköffnung 8 überstehende Ausgaberest stets sofort, also vorher, zurückgezogen. Es bleibt folglich kein der Austrocknung durch die umgebende Aussenluft ausgesetzter Rest. Entsprechend bildet sich auch kein erhärtender Stopfen. Vielmehr ist der in den unteren Bereich des Mundstückkanales zurückgezogene Anteil unmittelbar mit dem feuchten Vorrat verbunden. Andererseits führen auch zufällige Berührungen der Drucktasten-Betätigungsfläche um das Mass des Freiganges y nicht zur Ausgabe des Füllinhaltes. Der entsprechende Leerhub beträgt bei den aus der Zeichnung hervorgehenden Grössenverhältnissen etwas unter 1 mm. Bei grösserer Kolbenfläche und gleichem Arbeitshub durch die Drucktasten-Betätigungsfläche 10 muss der Leerhub y eine angemessene Vergrösserung erhalten.The mode of operation is as follows: the ready position given after the plug 9 is removed leads to the bellows-like compression of the practically dome-shaped head piece 6 displacing the portion of the pasty mass M present in the head piece, with the usual output amount being applied. However, this is only the case if, after passing through this empty stroke (clearance y), the rod 4 is also displaced by a so-called working stroke counter to the direction of the arrow x, that is to say in the direction of the ground. Due to the resetting of the head piece after the head piece has been released, the quantity dispensed is supplemented again by lifting the piston 2. Since it is raised under, albeit with a slight time delay, and the vacuum created in the head piece creates a suction force, the dispensing residue protruding through the mouthpiece opening 8 is always withdrawn immediately, that is to say beforehand. There is therefore no residue left to dry out due to the surrounding outside air. Accordingly, no hardening stopper is formed. Rather, the portion drawn back into the lower region of the mouthpiece channel is directly connected to the moist supply. On the other hand, accidental touches of the pushbutton actuation area by the amount of the clearance y do not result in the contents being output. The corresponding idle stroke is slightly less than 1 mm in the size ratios shown in the drawing. If the piston area is larger and the working stroke is the same due to the push button actuation area 10, the idle stroke y must be given an appropriate increase.

Das Kopfstück 6 ist von einer Kappe 14 überfangen. Letztere hält reibungs- oder formschlüssig an einer peripheren Wulst im Befestigungsbereich derselben zwischen unterem Kopfstückrand und Hals des Gehäuses 1. Durch Verlängerung der Mundstücköffnung 8, d.h. des Mundes bis in den Bereich der Innenwandung der Kappe 14 lässt sich aus dieser Massnahme ein Öffnungsverschluss erreichen.The head piece 6 is covered by a cap 14. The latter holds frictionally or positively on a peripheral bead in the area of attachment thereof between the lower edge of the headpiece and the neck of the housing 1. By extending the mouthpiece opening 8, i.e. of the mouth into the area of the inner wall of the cap 14, an opening closure can be achieved from this measure.
