Description

Die Erfindung betrifft einen Flüssigkeitsspender für ein in einem Vorratsbehälter enthaltenes fließfähiges Medium, wie Flüssigseife od. dgl. gemäß Oberbegriff des Patentanspruches 1.The invention relates to a liquid dispenser for one in one Storage containers contain flowable medium, such as liquid soap od. Like. According to the preamble of claim 1.

Ein derartiger Flüssigkeitsspender ist bspw. nach der FR-A-2184086 bekannt. Was dabei den Flüssigkeitsauslaßkanal und den Innenverschluß betrifft, so ist dieser derart ausgebildet, daß unterhalb seines Verschlußkopfes der Verschlußkorpus durchmesserreduziert ist und an diesem Teil radiale Rippen angeordnet sind, die mehrere, am Verschlußkorpus axial orientierte Auslaßkanäle begrenzen. Diese Kanäle bilden in Öffnungsstellung des Innenverschlusses gleichzeitig die freigestellten Einströmöffnungen für die Flüssigseife aus dem Vorratsbehälter. Ein solcher Behälter mit einem derartigen Verschluß funktioniert zwar einwandfrei, ist aber dennoch verbesserungsbedürftig, und zwar hinsichtlich der Wiederverwendbarkeit derartiger Behälter, die in der Regel aus Kunststoff bestehen und die, soweit bekannt, bislang und nach Entleerung einfach weggeworfen werden. Dies gilt auch für einen Flüssigkeitsspender bzw. Behälter nach der EP-A-114 026, der ebenfalls mit einem Innenverschluß versehen ist, welcher allerdings vollkommen in den Behälter eingestoßen werden muß und dann in der Füllung des Behälters gewissermaßen als verlorener Korken aufschwimmt. Im ersten Fall bleibt zwar der Innenverschluß in Öffnungsstellung im Flaschenhals sitzen, ist dabei aber praktisch einer Entfernung nicht mehr ohne weiteres zugänglich, d.h., einer schnellen industriellen Spülung und Wiederbefüllung sind diese Behälter nicht zugänglich, und es ist ebenso schwierig, den Innenverschluß wieder in Schließstellung zu bringen.Such a liquid dispenser is, for example, according to FR-A-2184086 known. What the liquid outlet channel and Internal closure relates, it is designed such that below its breechhead the breech body has a reduced diameter and radial ribs are arranged on this part are the several outlet channels axially oriented on the closure body limit. These channels form in the open position of the inner closure simultaneously the free inflow openings for the liquid soap from the storage container. A such a container with such a closure works flawless, but is still in need of improvement, and with regard to the reusability of such containers, which are usually made of plastic and which, if known, so far and after emptying are simply thrown away. This also applies to a liquid dispenser or container EP-A-114 026, which also has an inner closure which is, however, completely pushed into the container must be and then in the filling of the container to a certain extent floating up as a lost cork. In the first case the inner closure remains in the open position in the bottle neck sit, but is practically not a distance away more easily accessible, i.e., a fast industrial These containers are not accessible for rinsing and refilling, and it's just as difficult to get the inner lock back on to bring it into the closed position.

Der Erfindung liegt die Aufgabe zugrunde, einen Flüssigkeitsspender mit seinem zugehörigen Vorratsbehälter der gattungsgemäßen Art dahingehend zu verbessern, daß dieser trotz der Verwendung eines Innenverschlusses einer Wiederverwendung zugänglich gemacht werden kann. The invention has for its object a liquid dispenser with its associated storage container of the generic type Art to improve in spite of the use an inner lock accessible for reuse can be made.

Diese Aufgabe ist mit einem Flüssigkeitsspender der eingangs genannten Art nach der Erfindung durch die im Kennzeichen des Patentanspruches 1 angeführten Merkmale gelöst. Vorteilhafte Weiterbildungen ergeben sich nach den abhängigen Ansprüchen. Diese Lösung setzt zwar voraus, daß am Halter des Seifenspenders für den Anschlußhals ein mit entsprechendem Gewinde versehener Dorn vorgesehen sein muß, andererseits hat diese Lösung den Vorteil, daß sich umgekehrtwie beim Aufschrauben beim Herausdrehen des Anschlußhalses aus dem Halter des Spenders auch der Innenverschluß automatisch wieder schließt. Bei zwecks Wiederverwendung zwischengelagerter, weitgehend entleerter Vorratsbehälter hat dies den Vorteil, daß der Innenraum des Vorratsbehälters, in dem sich immer etwas Restflüssigkeit befinden wird, keinem bakteriellen Befall oder sonstigen Verunreinigungen ausgesetzt ist. Außerdem kann der Innenverschluß ohne weiteres zwecks Spülung und Neubefüllung mit einem einfachen Hilfswerkzeug gezogen werden, das, mit entsprechendem Gewinde versehen, lediglich mit ein oder zwei Gängen in die nach außen offene Hülse einzuschrauben ist, um den Innenverschluß ganz herausziehen zu können.This task is with a liquid dispenser at the beginning mentioned type according to the invention by the in the characteristics of Claim 1 solved features. Beneficial Further developments result from the dependent claims. This solution requires that the holder of the soap dispenser for the connection neck one with a corresponding thread Thorn must be provided, on the other hand, this solution has the Advantage that reverses as when unscrewing when unscrewing of the connection neck from the holder of the dispenser The inner lock closes automatically. When used for reuse intermediate, largely empty storage container this has the advantage that the interior of the storage container, in which there will always be some residual liquid, not exposed to bacterial or other contaminants is. In addition, the inner closure can be easily for flushing and refilling with a simple auxiliary tool be pulled, which, provided with the appropriate thread, only with one or two courses in the open to the outside Screw in the sleeve to pull out the inner lock completely to be able to.

Bevorzugt wird die Ausführungsform nach Anspruch 2 und folgenden. Der vorerwähnte korkenartige Innenverschluß hat bei der grundsätzlichen Lösung nämlich ein Innengewinde. Die Herstellung solcher Innengewinde verlangt aber relativ aufwendige Formwerkzeuge für die Spritzgußherstellung, um den betreffenden Gegenstand ausformen zu können. Da es sich beim Innenverschluß mit diesem Innengewinde um einen Massenartikel handelt hat es sich als wesentlich zweckmäßiger erwiesen, daß der Innenverschluß mit einem Außengewinde versehen ist und der Halter mit einer in bezug auf sein Innengewinde durchmesserkleineren, mit Abstand angeordneten Hülse mit an das Außengewinde des Innenverschlusses angepaßten Innengewinde.The embodiment according to claim 2 and following is preferred. The aforementioned cork-like inner closure has the basic solution namely an internal thread. The production such internal thread requires relatively complex Molds for injection molding to the relevant To be able to shape an object. Since it is the inner lock with this internal thread it is a mass article proved to be much more expedient that the inner closure is provided with an external thread and the holder with one with a smaller diameter in relation to its internal thread, with Spaced sleeve with the external thread of the inner closure adapted internal thread.

Der Effekt der automatischen Öffnung und Schließung des Innenverschlusses ist zwar der gleiche wie bei der grundsätzlcihen Lösung, aber die einfache Maßnahme der Anordnung eines Außengewindes am Innenverschluß hat den Vorteil, daß dieses Teil als Massenartikel mit wesentlich einfacherem Formwerkzeugaufwand herstellbar und leichter aus diesem auszuformen ist, und zwar genauso wie das Außengewinde am Anschlußhals des Vorratsbehälters. Die Anordnung von zwei Innengewinden am Halter des Flüssigkeitsspenders bzw. Doseurs ist zwar unumgänglich, andererseits fallen die Flüssigkeitsdoseure in nicht so hoher Stückzahl an, und der dafür erforderliche Aufwand ist von den Kosten her gesehen günstiger beim Doseur zu verkraften als beim Innenverschluß, bei dem es sich um einen Pfennigartikel handeln sollte.The effect of the automatic opening and closing of the inner lock is the same as with the basic one Solution, but the simple measure of arranging an external thread on the inner lock has the advantage that this part as Bulk items with much easier mold work producible and easier to mold from it, namely just like the external thread on the connection neck of the storage container. The arrangement of two internal threads on the holder of the liquid dispenser or doseers is inevitable, on the other hand the liquid dispensers do not fall in large numbers and the effort required to do so is dependent on the cost seen here cheaper to cope with the dose than with the inner closure, which is a penny item should.

Vorteilhafte Weiterbildungen bezüglich der bevorzugten Ausführungsform bestehen in Folgendem:

  • Die Gewinde zwischen Anschlußhals und Halter weisen eine Steigung auf, die gegenüber den Gewinden an der Hülse und dem Innenverschluß im wesentlichen um das Doppelte bis Dreifache größer ist.
  • Advantageous further developments with regard to the preferred embodiment consist in the following:
  • The threads between the connection neck and holder have a pitch which is substantially twice to three times greater than the threads on the sleeve and the inner closure.
  • Ferner ist der obere Rand der Hülse um eine Gewindeganghöhe tiefer angeordnet als der obere Rand des Halters und schließlich ist zentrisch in der Hülse ein im Querschnitt stern- oder kreuzförmiger, am oberen Ende konischer und in bezug auf den Querschnitt des Flüssigkeitsauslaßkanales im Innenverschluß geringfügig kleinerer Ausrichtzapfen angeordnet, der den oberen Rand des Halters überragt.Furthermore, the upper edge of the sleeve is around a thread height arranged lower than the top of the holder and finally is centrally in the sleeve a star or in cross section cruciform, conical at the top and with respect to the Cross section of the liquid outlet channel in the inner closure slightly smaller alignment pin arranged the top Overhanging the edge of the holder.

    Der erfindungsgemäße Flüssigkeitsspender wird nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert.The liquid dispenser according to the invention is described below the graphic representation of exemplary embodiments explained in more detail.

    Die den Flüssigkeitsspender bildenden Teile, nämlich Flüssigkeitsdoseur 4 und Vorratsbehälter 1 sind nur gestrichelt angedeutet, wobei der Flüssigkeitsspender besteht aus den in einem mit einem zentrischen Öffnungszapfen 2 versehenen Halter 3 des über Kopf angeordneten, flaschenförmigen Vorratsbehälters 1 mit einem mit Außengewinde 5 versehenem Anschlußhals 6, in dem ein korkenartiger Innenverschluß 7 angeordnet ist, der im Anschlußhals 6 aus seiner Schließstellung in Öffnungsstellung verschieblich gelagert und am Innenverschluß 7 unterhalb seines Verschlußkopfes 8 mindestens eine in Öffnungsstellung freigestellte Öffnung 9 angeordnet ist, an die sich im Halter 3 ein Flüssigkeitsauslaßkanal 10 anschließt. Für diesen Flüssigkeitsspender ist nun unter Verweis auf Fig. 1A wesentlich, daß der Innenverschluß 7 zur Ausflußseite hin als offene Hülse 7' ausgebildet und diese mit einem auf den Öffnungszapfen 2 des Halters 3 aufschraubbaren Gewinde 11 mit zum Gewinde 5 des Anschlußhalses 6 gleichgerichteter Steigung versehen ist und die Steigung der Gewinde 11, 11' der Hülse 7'' und des Öffnungszapfens 2 kleiner ist als die Steigung der Gewinde 5, 5' des Anschlußhalses 6 und des zugehörigen Halters 3. Beim Einschrauben des Anschlußhalses 6 in das Gewinde 5' des Halters 3 kommt dabei auch die Hülse 7' des Innenverschlusses 7 mit dem Gewinde 11' des Öffnungszapfens 2 in Eingriff und schraubt sich ausgehend von der Schließstellung gemäß Fig. 1A über die Zwischenstellung gemäß Fig. 1B in die Öffnungsstellung gemäß Fig. 1C automatisch mit auf. Beim Ausschrauben des Anschlußhalses 2 erfolgt umgekehrt wieder das gleiche, d.h., es wird dann wieder die Schließstellung gemäß Fig. 1A erreicht. Um den Innenverschluß 7 dann zwecks Spülung und Neubefüllung entfernen zu können, ist lediglich ein im Sinne des Öffnungszapfens 2 ausgebildetes Hilfswerkzeug ein oder zwei Gänge in die Hülse 7' einzuschrauben, und der ganze Innenverschluß 7 kann herausgezogen werden. Um sicherzustellen, daß sich der Innenverschluß 7 beim Verschrauben in bezug auf den Flaschenhals 2 nicht dreht, kann zwischen Innenwand des Flaschenhalses 2 und dem Innenverschluß 7 an geeigneter Stelle eine Verdrehsicherung angeordnet werden, was nicht besonders dargestellt und zu erläutern ist. Zwingend notwendig ist eine solche Verdrehsicherung jedoch nicht, da der Verschlußkopf 8 ausreichend straff im Anschlußhals 2 sitzt.The parts forming the liquid dispenser, namely the liquid dispenser 4 and storage container 1 are only indicated by dashed lines, where the liquid dispenser consists of the one with a central opening pin 2 holder 3 of the bottle-shaped storage container 1 arranged overhead with an externally threaded 5 connecting neck 6 in which a cork-like inner closure 7 is arranged in the connection neck 6 from its closed position to the open position slidably mounted and on the inner closure 7 below his Closure head 8 at least one exempt in the open position Opening 9 is arranged, which in the holder 3 Liquid outlet channel 10 connects. For this liquid dispenser it is essential with reference to Fig. 1A that the Inner closure 7 to the outflow side as an open sleeve 7 ' and this with one on the opening pin 2 of the holder 3 screwable thread 11 with thread 5 of the connection neck 6 rectified slope is provided and the pitch of the threads 11, 11 'of the sleeve 7' 'and the opening pin 2 is smaller than the pitch of the threads 5, 5 ' of the connecting neck 6 and the associated holder 3. When screwing in of the connecting neck 6 into the thread 5 'of the holder 3 comes the sleeve 7 'of the inner closure 7 with the Thread 11 'of the opening pin 2 engages and screws starting from the closed position according to FIG. 1A via the intermediate position 1B in the open position shown in FIG. 1C automatically on. When unscrewing the connection neck 2 conversely, the same thing happens again, i.e., it will be again 1A reaches the closed position. To the inner closure 7 can then be removed for rinsing and refilling, is only a trained in the sense of the opening pin 2 Screwing auxiliary tool one or two gears into the sleeve 7 ', and the whole inner lock 7 can be pulled out will. To ensure that the inner closure 7 at Screwing in relation to the bottle neck 2 does not rotate between the inner wall of the bottle neck 2 and the inner closure 7 an anti-rotation device is arranged at a suitable point, which is not particularly shown and to be explained. Mandatory However, such an anti-rotation device is not necessary since the Sealing head 8 is sufficiently tight in the connection neck 2.

    Die bevorzugte Ausführungsform ist in den Fig. 2A, B und 3 dargestellt, die sich von der vorbeschriebenen im wesentlichen nur dadurch unterscheidet, daß das Gewinde 11 einer den Öffnungszapfen 2 bildenden Hülse 2' des Halters 3 ein Innengewinde und das Gewinde 11' des Innenverschlusses 7 ein entsprechendes Außengewinde ist. Auch hierbei haben die Gewinde 5, 5' eine Steigung, die gegenüber den Gewinden 11, 11' im wesentlichen um das Doppelte bis Dreifache größer ist. Ferner ist hierbei auch der obere Rand 12 der Hülse 2' um eine Gewindeganghöhe tiefer angeordnet als der obere Rand 13 des Halters 3.The preferred embodiment is shown in FIGS. 2A, B and 3, which differs from the above essentially only differs in that the thread 11 one the opening pin 2 forming sleeve 2 'of the holder 3 an internal thread and the thread 11 'of the inner closure 7 has a corresponding external thread is. Here, too, the threads 5, 5 'have a pitch, compared to the threads 11, 11 'essentially by Is twice to three times larger. Furthermore, the the upper edge 12 of the sleeve 2 'arranged lower by a thread pitch than the upper edge 13 of the holder 3.

    Der Abstand A zwischen Hülse 2' und Halter 3 muß dabei so bemessen sein, daß der Anschlußhals 6 des Vorratsbehälters 1 mit Spiel zwischen Hülse 2' und Halter 3 paßt.The distance A between the sleeve 2 'and the holder 3 must be so dimensioned be that the connection neck 6 of the storage container 1 with Match between sleeve 2 'and holder 3 fits.

    Ferner ist vorteilhaft, wie in den Fig. 2, 3 dargestellt, zentrisch in der Hülse 2' ein im Querschnitt stern- oder kreuzförmiger, am oberen Ende konischer und in bezug auf den Querschnitt des Flüssigkeitsauslaßkanales 10' im Innenverschluß 7 geringfügig kleinerer Ausrichtzapfen 13 angeordnet, der den oberen Rand 13 des Halters 3 überragt. Da der Innenverschluß 7 nur mit seinem Verschlußkopf 7' im Anschlußhals 6 sitzt, dessen immer genau koaxialer Sitz zum Anschlußhals 6 nicht immer gewährleistet ist, garantiert der Ausrichtzapfen 13 mit seinem wie dargestellt konischen Ende beim Einschrauben bzw. schon beim Aufsetzen des Anschlußhalses 6 eine axiale Ausrichtung des Innenverschlusses 7 und damit einen funktionsgerechten Eingriff des Außengewindes 11' in das Innengewinde 11 der Hülse 2'. Die stern- bzw. kreuzförmige Querschnittsausbildung des Ausrichtzapfens 13 ist dabei notwendig, um Auslaßpassagen für die Flüssigkeit zu schaffen, die in Öffnungsstellung (Fig. 2B) aus dem Vorratsbehälter 1 durch die freigestellten Öffnungen 9 in diese Passagen 14 gelangt.Furthermore, as shown in FIGS. 2, 3, it is advantageous to be centric in the sleeve 2 'a star-shaped or cross-shaped in cross section, conical at the upper end and in relation to the cross section of the liquid outlet channel 10 'in the inner closure 7 slightly smaller alignment pin 13 arranged, the overhangs the upper edge 13 of the holder 3. Since the inner lock 7 only sits with its locking head 7 'in the connecting neck 6, the always exactly coaxial fit to the connection neck 6 not always guaranteed is guaranteed, the alignment pin 13 with its as shown conical end when screwing in or already when placing the connection neck 6 an axial alignment of the Inner closure 7 and thus a functional intervention of the external thread 11 'into the internal thread 11 of the sleeve 2'. The star-shaped or cross-shaped cross-sectional formation of the alignment pin 13 is necessary to make outlet passages for the liquid to create the in the open position (Fig. 2B) from the Storage container 1 through the exposed openings 9 in this Passages 14 arrives.

    Ein solcher Ausrichtzapfen 13 ist bei der Ausführungsform nach Fig. 1A-1C nicht erforderlich, da dort der Innenverschluß mit axialen Rippen 15 zentrisch über eine relativ große Länge geführt ist, zwischen welchen Rippen 15 sich bei dieser Ausführungsform die Auslaßpassagen 10' befinden.Such an alignment pin 13 is in the embodiment of Fig. 1A-1C not necessary because there the inner closure with axial ribs 15 guided centrally over a relatively large length is between which ribs 15 are in this embodiment the outlet passages 10 'are located.
