Abstract

The device incorporates a compressor (2) driven by a mains or battery-powered electric motor (3) to fill a pair of equalising containers (7,7') from a compressed-air line (5) via a non-return valve (4). The containers are connected to a delivery valve (8) which can supply a correlated valve and cartridge. A pressure control circuit (11) maintains a preset constant pressure in the container, and switches-out the motor automatically if a maximum pressure of e.g. 7 atmospheres is attained.

Description

Die vorliegende Erfindung betrifft eine neue Abgabevorrichtung für fließfähige Materialien wie Lösungen, Dispersionen, Gele, Emulsionen, Pasten, etc.The present invention relates to a new dispenser for flowable materials such as solutions, dispersions, gels, emulsions, pastes, etc.

Die Verwendung von Aerosolen zur Applikation solcher Materialien mit Hilfe gelöster bzw. komprimierter Treibmittel wie (Fluor)-Kohlenwasserstoffen, Kohlendioxid, Dimethylether, etc. ist seit langem bekannt, jedoch in den letzten Jahren, zum Teil aus Umweltschutzgründen, nicht unumstritten.The use of aerosols for the application of such materials with the aid of dissolved or compressed propellants such as (fluorine) hydrocarbons, carbon dioxide, dimethyl ether, etc. has been known for a long time, but has not been uncontroversial in recent years, partly for environmental reasons.

Es hat daher nicht an Versuchen gefehlt, diese Aerosole durch andere Abgabemechanismen zu ersetzen, z. B. Pumpsprühdosen, wo letztlich Luft als Treibmittel dient.There has been no shortage of attempts to replace these aerosols with other delivery mechanisms, e.g. B. pump spray cans, where air is ultimately used as a blowing agent.

Diese Ersatzvorrichtungen sind jedoch häufig umständlich handhabbar und nicht für alle Anwendungszwecke einzusetzen, auch der Sprühstrahl ist für die Applikation zahlreicher Produkte nicht homogen genug.However, these replacement devices are often cumbersome to handle and cannot be used for all purposes, and the spray jet is also not homogeneous enough for the application of numerous products.

Es ist darüber hinaus auch bekannt, zylinderförmige Kartuschen, die mit einem Abgabeventil versehen sind und in die ein weiteres zusammendrückbaren Produktbehältnis auswechselbar eingebracht werden kann, dessen Inhalt durch Druckausübung durch in der Kartusche vorhandenes Treibmittel, z.B. Druckluft, das dieser durch ein verschließbares Bodenventil zugeführt wird, abgegeben wird, als wiederverwendbare Druckdosen einzusetzen.It is also known, cylindrical cartridges, which are provided with a dispensing valve and into which a further compressible product container can be interchangeably inserted, the content of which is exerted by pressure from propellant present in the cartridge, e.g. Compressed air, which is supplied through a lockable bottom valve, is used as reusable pressure cans.

Solche Abgabevorrichtungen sind beispielsweise in der DE-A 40 09 705 und der DE-A 40 02 580 beschriebenSuch dispensing devices are described for example in DE-A 40 09 705 and DE-A 40 02 580

Soweit in diesen Druckluft als Treibmittel benutzt wird, sind sie jedoch nicht geeignet, einen konstanten Betrieb sicherzustellen, da ein zwischenzeitlich erforderlich werdendes Nachtfüllen des Treibmittels, z. B. bei Druckabfall, nicht möglich ist.As far as is used in this compressed air as a blowing agent, they are not suitable to ensure constant operation, since an intermediate refilling of the blowing agent, e.g. B. with pressure drop is not possible.

Hier setzt nun die vorliegende Erfindung ein:This is where the present invention comes in:

Sie geht von der Aufgabenstellung aus, ein kompaktes, nicht störungsanfälliges, ökonomisch arbeitendes Abgabesystem zu schaffen, das einen kontinuierlichen Betrieb zur Abgabe verschiedener fließfähiger Materialien mittels Druckluft gestattet.It is based on the task of creating a compact, economically working dispensing system that is not susceptible to faults and that permits continuous operation for dispensing various flowable materials by means of compressed air.

Dieses Abgabesystem besteht, in Lösung dieser Aufgabe, aus einem zur Luftdruckerzeugung dienenden Kompressor und mindestens einem damit verbundenen Vorratsbehälter zur Aufnahme von Druckluft, der ein Ausgangsventil aufweist, das die Verbindung zur Druckabgabe an Kartuschen mittels deren dazu korrelierenden Bodenventils gewährleistet, wobei in diese Kartuschen auswechselbar ein zusammendrückbares Produktbehältnis eingebracht ist.In order to achieve this object, this delivery system consists of a compressor which serves to generate air pressure and at least one associated storage container for receiving compressed air, which has an outlet valve which ensures the connection for pressure delivery to cartridges by means of their correlating bottom valve, whereby cartridges can be replaced a compressible product container is inserted.

Aus der DE-C2 42 26 419 ist eine Einrichtung zum Füllen von Luft in Aerosolzerstäuber bekannt, die einen Kompressor aufweist, über den mittels einer Sicherheitsschaltung, die das Einschalten des Kompressors nur dann gewährleistet, wenn ein Aerosolzerstäuber in einer speziellen Sicherheitsposition an eine Lufteinlaßrichtung angeschlossen ist, Druckluft zum Zerstäuberbehälter zugeführt werden kann. Eine Füllung der Aerosoldose ohne eingeschalteten Motor ist dadurch ausgeschlossen.From DE-C2 42 26 419 a device for filling air into aerosol atomizers is known, which has a compressor, by means of a safety circuit which only ensures that the compressor is switched on when an aerosol atomizer is connected to an air inlet direction in a special safety position is, compressed air can be supplied to the atomizer container. Filling the aerosol can without the engine switched on is therefore excluded.

Durch die erfindungsgemäße Vorrichtung ist es demgegenüber möglich, auf einfache und schnelle Art Kartuschen mit Druckluft zu füllen, und auch Füllungen ohne Einschalten des Kompressors vorzunehmen, z.B. wenn keine Möglichkeit besteht, den Motor des Kompressors wegen einer fehlenden Stromquelle zu betätigen.In contrast, the device according to the invention makes it possible to fill cartridges with compressed air in a simple and quick manner, and also to carry out fillings without switching on the compressor, e.g. if there is no way to operate the compressor motor due to a lack of power source.

Nach einer bevorzugten Ausführungsform der Erfindung besteht der Vorratsbehälter für die Druckluftaufnahme aus mindestens einem druckgeprüften Ausgleichsbehältnis, beispielsweise einer Aerosoldose, dessen Aufnahmevermögen an Druckluft mindestens für zwei, insbesondere mindestens vier zu füllende Kartuschen ausreicht.According to a preferred embodiment of the invention, the storage container for the compressed air intake consists of at least one pressure-tested compensation container, for example an aerosol can, the absorption capacity of compressed air of which is sufficient for at least two, in particular at least four, cartridges to be filled.

Die Verbindung zwischen Kompressor und Vorratsbehälter(n) ist zweckmäßigerweise mit einer Drucksteuerschaltung versehen, die der Aufrechterhaltung eines konstanten Druckniveaus dient und den Kompressor immer dann einschaltet, wenn das Druckniveau im Vorratsbehälter, das vorzugsweise zwischen etwa 5 bis 7 bar liegt, unterschritten wird.The connection between the compressor and the storage container (s) is expediently provided with a pressure control circuit which serves to maintain a constant pressure level and which switches the compressor on whenever the pressure level in the storage container, which is preferably between about 5 and 7 bar, is fallen below.

Zur Sicherheit des Druckluftsystems weist das Ausgangsventil des Vorratsbehälters vorzugsweise ein Rückschlagsventil auf.For the safety of the compressed air system, the outlet valve of the storage container preferably has a check valve.

Die erfindungsgemäße Abgabevorrichtung ist vorzugsweise mit einer Einrichtung zum Ablassen überschüssiger Druckluft aus der Kartusche, beispielsweise nach Entleerung des in ihr eingebrachten zusammendrückbaren Produktbehältnisses, durch das Bodenventil derselben versehen.The dispensing device according to the invention is preferably provided with a device for releasing excess compressed air from the cartridge, for example after emptying the compressible product container introduced into it, through the bottom valve thereof.

Einzelheiten der beispielhaften Gestaltung einer erfindungsgemäßen Vorrichtung ergeben sich aus den im folgenden detailliert beschriebenen Figuren 1 bis 4.Details of the exemplary design of a device according to the invention can be found in FIGS. 1 to 4 described in detail below.

Figur 1 stellt eine schematische Draufsicht auf eine erfindungsgemäße Abgabevorrichtung dar. In einem Gehäuse 1 ist ein handelsüblicher Kompressor 2, der durch einen an das Stromnetz anzuschließenden oder einen Akkumulator aufweisenden Elektromotor 3 betrieben wird, mittels eines Rückschlagsventils 4 über eine Druckluftleitung 5 mit einem Vorratsbehälter 6 verbunden, der aus zwei miteinander gekoppelten Ausgleichsbehältnissen 7 und 7' besteht. Der Vorratsbehälter 6 steht in Verbindung mit dem Ausgangsventil 8, das an ein (nicht dargestelltes) dazu korrelierendes Bodenventil einer mit Druckluft zu füllenden Kartusche angeschlossen werden kann.1 shows a schematic top view of a dispensing device according to the invention. In a housing 1 there is a commercially available compressor 2, which is operated by an electric motor 3 to be connected to the mains or has an accumulator, by means of a check valve 4 via a compressed air line 5 with a storage container 6 connected, which consists of two interconnected expansion tanks 7 and 7 '. The reservoir 6 is connected to the outlet valve 8, which can be connected to a bottom valve (not shown) that correlates to this, of a cartridge to be filled with compressed air.

Über einen Schalter 10 und entsprechende Leitungen 9 kann die Vorrichtung an das Stromnetz angeschlossen werden.The device can be connected to the mains via a switch 10 and corresponding lines 9.

Die Vorrichtung weist darüber hinaus zweckmäßigerweise eine Drucksteuerschaltung 11 zur Aufrechterhaltung eines zuvor eingestellten konstanten Druckniveaus innerhalb des Vorratsbehälters 6 auf. Wird das maximale Druckniveau (z.B. 7 bar) erreicht, wird der Elektromotor automatisch ausgeschaltet. Bei Unterschreiten der Untergrenze des eingestellten Drucks schaltet sich der Motor wieder ein, bis der Maximaldruck erneut erreicht ist.The device also expediently has a pressure control circuit 11 for maintaining a previously set constant pressure level within the reservoir 6. If the maximum pressure level (e.g. 7 bar) is reached, the electric motor is automatically switched off. If the pressure drops below the lower limit, the motor switches on again until the maximum pressure is reached again.

Dem Ausgangsventil 8 kann ein Rückschlagventil zugeordnet sein, um ein durch ein in der Kartusche befindliches, möglicherweise defektes Produktbehältnis bedingtes Eindringen von fließfähigem Produkt in das Befüllungssystem zu verhindern.A check valve can be assigned to the outlet valve 8 in order to prevent flowable product from penetrating into the filling system due to a possibly defective product container located in the cartridge.

Das Volumen des Vorratsbehälters 6 wird so gewählt, daß ein druckgefüllter Vorratsbehälter, ohne daß eine Drucknachfüllung möglich ist, z. B. bei fehlender Stromquelle, eine Auffüllung von mehreren Kartuschen gewährleisten kann. Das Volumen kann vorzugsweise auf mehrere Ausgleichsbehältnisse 7, 7' aufgeteilt werden, damit die Abgabevorrichtung klein und kompakt gestaltet werden kann. Der Kompressor 2 und das gesamte Drucksystem sind vorzugsweise so ausgelegt, daß bei einem Arbeitsniveau von 5 bis 7 bar ein maximaler Druck von 8 bar erzeugt werden kann, was auch nur einen kleinen Motor 3 erfordert.The volume of the reservoir 6 is chosen so that a pressure-filled reservoir without a pressure refill is possible, for. B. in the absence of a power source, can ensure filling of several cartridges. The volume can preferably be divided into a plurality of expansion containers 7, 7 'so that the dispensing device can be made small and compact. The compressor 2 and the entire pressure system are preferably designed so that a maximum pressure of 8 bar can be generated at a working level of 5 to 7 bar, which also requires only a small motor 3.

Figur 2 zeigt eine beispielhafte Wiedergabe der äußeren Erscheinungsform einer erfindungsgemäßen Abgabevorrichtung mit dem Ausgangsventil 8, auf das die zu füllende Kartusche mit ihrem Bodenventil paßförmig aufgesetzt werden kann.Figure 2 shows an exemplary representation of the external appearance of a dispensing device according to the invention with the outlet valve 8, on which the cartridge to be filled with its bottom valve can be fitted.

Figur 3 zeigt eine ähnliche Vorrichtung wie Figur 2, weist aber noch eine zusätzliche Einrichtung 11 auf, die ebenfalls mit dem Bodenventil der Kartusche korreliert und durch die eventuell in der Kartusche vorhandene, nicht mehr benötigte Druckluft abgelassen werden kann.FIG. 3 shows a device similar to FIG. 2, but has an additional device 11, which also correlates with the bottom valve of the cartridge and can be discharged through the compressed air that may be no longer required in the cartridge.

Figur 4 skizziert die detaillierte Ausgestaltung dieser Einrichtung 11 mittels einer Druckablaßvorrichtung 12 als Pin, a) im Ruhezustand, und b) im aktivierten Zustand.FIG. 4 outlines the detailed configuration of this device 11 by means of a pressure relief device 12 as a pin, a) in the idle state and b) in the activated state.

Die erfindungsgemäß Vorrichtung kann zur Abgabe aller möglichen fließfähigen Produkte verwendet werden, z.B. kosmetische Produkte, wie Hautcremes, Gele, Zahnpasta, Haarpflegemittel wie Oxidationshaarfärbemittel, Haarwaschmittel, Shampoos, Haushalts- und Industriereinigungsmittel, Lebensmittel wie Senf, Ketchup, etc.The device according to the invention can be used to dispense all possible flowable products, e.g. cosmetic products, such as skin creams, gels, toothpaste, hair care products such as oxidation hair colorants, shampoos, shampoos, household and industrial cleaning agents, foods such as mustard, ketchup, etc.
