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 a flowable medium contained in a storage container, such as liquid soap or the like. According to the preamble of patent 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 known, for example, from FR-A-2184086. As far as the liquid outlet channel and the inner closure are concerned, it is designed in such a way that the closure body is reduced in diameter below its closure head and radial ribs are arranged on this part, which delimit a plurality of outlet channels which are axially oriented on the closure body. In the open position of the inner closure, these channels simultaneously form the free inflow openings for the liquid soap from the storage container. Such a container with such a closure works perfectly, but is still in need of improvement, namely with regard to the reusability of such containers, which generally consist of plastic and which, as far as is known, have so far been simply thrown away and after being emptied. This also applies to a liquid dispenser or container according to EP-A-114 026, which is also provided with an inner closure, which, however, has to be pushed completely into the container and then floats in the filling of the container to a certain extent as a lost cork. In the first case, the inner closure remains in the open position in the bottle neck, but is practically no longer easily accessible for removal, ie these containers are not accessible for rapid industrial rinsing and refilling, and it is just as difficult to close the inner closure again bring to.

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 to improve a liquid dispenser with its associated storage container of the generic type in such a way that it can be made available for reuse despite the use of an inner closure.

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 object is achieved with a liquid dispenser of the type mentioned according to the invention by the features stated in the characterizing part of patent claim 1. Advantageous further developments result from the dependent claims. Although this solution requires that a threaded mandrel must be provided on the holder of the soap dispenser for the connection neck, on the other hand, this solution has the advantage that, conversely, when screwing the connection neck out of the holder of the dispenser, the inner closure automatically again closes. If intermediate, largely emptied storage containers are re-used, this has the advantage that the interior of the storage container, in which there will always be some residual liquid, is not exposed to bacterial contamination or other contaminants. In addition, the inner closure can be easily removed for flushing and refilling with a simple auxiliary tool, which, provided with the appropriate thread, can only be screwed into the outwardly open sleeve with one or two gears in order to be able to pull the inner closure out completely.

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 above-mentioned cork-like inner closure has an internal thread in the basic solution. The production of such internal threads, however, requires relatively complex molds for injection molding in order to be able to mold the object in question. Since the internal lock with this internal thread is a mass-produced article, it has proven to be much more expedient that the internal lock is provided with an external thread and the holder with a sleeve which is smaller in diameter with respect to its internal thread and is arranged at a distance with the external thread of the internal lock 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 in the basic solution, but the simple measure of arranging an external thread on the inner lock has the advantage that this part as Bulk articles can be produced with much simpler mold work and easier to mold from them, in exactly the same way as 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 dispenser is inevitable, on the other hand, the liquid dispensers do not come in as large numbers, and the effort required for this is more cost-effective for the doser than for the internal closure, where it is should be a penny item.

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 arranged a thread pitch lower than the upper edge of the holder and finally in the sleeve is a star-shaped or cruciform in cross-section, conical at the upper end and slightly smaller in relation to the cross-section of the liquid outlet channel in the inner closure arranged, which projects above the upper 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 explained in more detail below with reference to the drawing of exemplary embodiments.

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 S versehen ist und die Steigung S der Gewinde 11, 11' der Hülse 7'' und des Öffnungszapfens 2 kleiner ist als die Steigung S 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 liquid dispenser 4 and storage container 1 are only indicated by dashed lines, the liquid dispenser consisting of the holder 3 of the bottle-shaped storage container 1, which is provided with a central opening spigot 2, and has a connection neck 6 provided with an external thread 5, in which a cork-like inner closure 7 is arranged, which is displaceably mounted in the connecting neck 6 from its closed position in the open position and on the inner closure 7 below its closure head 8 at least one opening 9 is provided in the open position, to which a liquid outlet channel 10 connects in the holder 3. For this liquid dispenser, it is now essential, with reference to FIG. 1A, that the inner closure 7 on the outflow side is designed as an open sleeve 7 'and this with a thread 11 screwable onto the opening pin 2 of the holder 3 with a pitch S which is rectified to the thread 5 of the connecting neck 6 is provided and the pitch S of the thread 11, 11 'of the sleeve 7''and the opening pin 2 is smaller than the pitch S of the thread 5, 5' of the connecting neck 6 and the associated holder 3. When screwing the connecting neck 6 into the thread 5 'of the holder 3, the sleeve 7' of the inner closure 7 also engages with the thread 11 'of the opening pin 2 and, starting from the closed position according to FIG. 1A, screws into the open position according to FIG. 1B into the open position according to FIG. 1C automatically with on. When unscrewing the connection neck 2, the same thing takes place in reverse, ie the closed position according to FIG. 1A is then reached again. In order to be able to remove the inner closure 7 for the purpose of flushing and refilling, only an auxiliary tool designed in the sense of the opening pin 2 has to be screwed into the sleeve 7 'by one or two gears, and the whole inner lock 7 can be pulled out. To ensure that the inner closure 7 does not rotate when screwing in relation to the bottle neck 2, an anti-rotation device can be arranged at a suitable point between the inner wall of the bottle neck 2 and the inner closure 7, which is not particularly shown and explained. However, such an anti-rotation device is not absolutely necessary, since the closure head 8 is seated sufficiently tightly 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 in that the thread 11 of a sleeve 2 'forming the opening pin 2' of the holder 3 has an internal thread and the thread 11 'of the inner closure 7 is a corresponding external thread. Here, too, the threads 5, 5 'have a pitch which is substantially twice to three times greater than the threads 11, 11'. Furthermore, the upper edge 12 of the sleeve 2 'is also arranged one thread lower 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 such that the connection neck 6 of the storage container 1 fits with play between the sleeve 2' and the holder 3.

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, a centering pin 13 which is star-shaped or cruciform in cross section, conical at the upper end and slightly smaller in relation to the cross section of the liquid outlet channel 10 'is arranged centrally in the sleeve 2' that protrudes above the upper edge 13 of the holder 3. Since the inner closure 7 sits only with its closure head 7 'in the connection neck 6, whose always exactly coaxial fit to the connection neck 6 is not always guaranteed, the alignment pin 13 guarantees with its conical end as shown when screwing in or already when the connection neck 6 is put on Alignment of the inner closure 7 and thus a functional engagement of the external thread 11 'in the internal thread 11 of the sleeve 2'. The star-shaped or cross-shaped cross-sectional configuration of the alignment pin 13 is necessary in order to create outlet passages for the liquid which, in the open position (FIG. 2B), passes from the storage container 1 through the exposed openings 9 into these passages 14.

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 not necessary in the embodiment according to FIGS. 1A-1C, since there the inner closure with axial ribs 15 is guided centrally over a relatively large length, between which ribs 15 the outlet passages 10 'are located in this embodiment.
