Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen und Versprühen einer aus wenigstens zwei Komponenten, z. B Flüssigkeiten, und einem Treibgas bestehenden Mischung gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a device for producing and spraying one of at least two components, for. B liquids, and a mixture of propellant according to the preamble of claim 1.

Eine derartige Vorrichtung ist im Prinzip aus der US-A-3 635 261 (Fig. 5 bis 7) bekannt, wobei der äußere Behälter zwei voneinander getrennte Kammern umfaßt, von denen die eine zwischen dem inneren Behälter und dem Boden des äußeren Behälters ausgebildet ist. Diese umfaßt eine Druckgasfüllung. Mit einem im Boden des äußeren Behälters bereits eingeführten Aufbrechdorn läßt sich eine Fluidverbindung zwischen der Druckgaskammer und dem inneren Behälter herstellen, wobei zu diesem Zweck die bodenseitige Sollbruchstelle mit dem Aufbrechdorn geöffnet wird. Durch das dann in den inneren Behälter gelangende Druckgas und den sich dort aufbauenden Überdruck wird eine der bodenseitigen Sollbruchstelle gegenüberliegende und relativ großflächige Membran aufgebrochen, so daß eine Fluidverbindung zwischen dem inneren Behälter und der zweiten Kammer des äußeren Behälters hergestellt ist.Such a device is known in principle from US-A-3 635 261 (Figs. 5 to 7), the outer container comprising two separate chambers, one of which is formed between the inner container and the bottom of the outer container . This includes a pressurized gas filling. A fluid connection between the compressed gas chamber and the inner container can be established with a break-up mandrel already introduced in the bottom of the outer container, the predetermined breaking point on the bottom side being opened with the break-up mandrel for this purpose. The compressed gas then entering the inner container and the excess pressure building up there breaks up a relatively large-area membrane opposite the predetermined breaking point on the bottom, so that a fluid connection is established between the inner container and the second chamber of the outer container.

Problematisch ist bei der bekannten Konstruktion, eine dauerhafte Dichtung zwischen dem Inneren des äußeren Behälters und der Umgebung sicherzustellen, vor allem dann, wenn durch äußere Einwirkungen, wie z. B. erhöhte Umgebungstemperatur, der Druck im äußeren Behälter übermäßig ansteigt, oder wenn der äußere Behälter mit chemisch aggressiven Komponenten gefüllt ist.It is problematic in the known construction to ensure a permanent seal between the interior of the outer container and the environment, especially when due to external influences, such as. B. increased ambient temperature, the pressure in the outer container increases excessively, or when the outer container is filled with chemically aggressive components.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, bei der eine dauerhafte Abdichtung zwischen dem Inneren des äußeren Behälters und der Umgebung gewährleistet ist, und bei der eine ausreichende Fluiddichtung zwischen dem Inneren des äußeren Behälters und der Umgebung auch beim Gebrauch aufrechterhalten wird.The present invention has for its object to provide a device of the type mentioned, in which a permanent seal between the interior of the outer container and the environment is guaranteed, and in which a sufficient fluid seal between the interior of the outer container and the environment also is maintained during use.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst.This object is achieved by the characterizing features of claim 1.

Dadurch, daß die dem Locher zugeordnete axiale Führungsbohrung im Boden des äußeren Behälters behälterinnenseitig durch eine Verschlußmembran verschlossen ist, ist vor dem Gebrauch eine dauerhafte Fluiddichtung zwischen dem Inneren des äußeren Behälters und der Umgebung sichergestellt. Diese Fluiddichtung wird beim Gebrauch nicht unterbrochen, da erfindungsgemäß die axiale Erstreckung des Fluiddurchgangs im Locher kleiner ist als die Länge der axialen Führungsbohrung im Boden des äußeren Behälters. Durch den derart ausgebildeten Locher in Kombination mit der membranverschlossenen Axialführung für den Locher im Boden des äußeren Behälters läßt sich also eine Fluidverbindung zwischen innerem und äußerem Behälter ohne Gefahr eines unbeabsichtigten Entweichens der Komponenten in die Umgebung herstellen.Characterized in that the axial guide bore associated with the hole in the bottom of the outer container is closed on the inside of the container by a closure membrane, a permanent fluid seal between the inside of the outer container and the environment is ensured before use. This fluid seal is not interrupted in use, since according to the invention the axial extent of the fluid passage in the hole is smaller than the length of the axial guide bore in the bottom of the outer container. The perforator designed in this way, in combination with the membrane-sealed axial guide for the perforator in the bottom of the outer container, allows a fluid connection between the inner and outer container to be established without the risk of the components accidentally escaping into the environment.

Weitere konstruktive Details der erfindungsgemäßen Vorrichtung sind in den Unteransprüchen beschrieben.Further structural details of the device according to the invention are described in the subclaims.

Die Vorrichtung bzw. der Zweikammerbehälter gemäß Fig. 1 umfaßt einen äußeren Standard-Aerosol-Behälter 1 mit einem Aerosol-Abgabeventil 3, das in üblicher Weise in einem am Öffnungsrand 29 des Behälters 1 dicht befestigten Deckel 30 gefaßt ist sowie einen inneren Behälter 2 der aus einem ebenso korrosionsbeständigem Material besteht wie der äußere Behälter 1. Der äußere Behälter 1 enthält eine Füllgutkomponente A, der innere Behälter 2 eine Füllgutkomponente B sowie ein geeignetes Treibmittel T, welches im allgemeinen ein leicht verflüssigbares Gas, z.B. Butan-Propan, od.dgl., ist. Die innere Füllgutkomponente B kann z.B. Wasserstoffperoxyd und die Füllgutkomponente A ein Farbstoff sein. Die Abmessungen der Behälter 1 und 2 richten sich nach den abzugebenden Füllgutvolumina und deren Verhältnis. Maximal kann der Durchmesser des inneren Behälters 2 knapp so groß sein wie der des Öffnungsrandes 29 des äußeren Behälters 1, so daß der innere Behälter 2 noch durch diese Öffnung in den äußeren Behälter 1 eingeführt werden kann. Für gängige Größen sind diese Abmessungen genormt.The device or the two-chamber container according to FIG. 1 comprises an outer standard aerosol container 1 with an aerosol dispensing valve 3, which is held in a conventional manner in a lid 30 tightly attached to the opening edge 29 of the container 1 and an inner container 2 consists of an equally corrosion-resistant material as the outer container 1. The outer container 1 contains a filling component A, the inner container 2 contains a filling component B and a suitable propellant T, which is generally an easily liquefiable gas, eg Butane-propane or the like. The inner filling component B can e.g. Hydrogen peroxide and the filling component A can be a dye. The dimensions of the containers 1 and 2 depend on the volume of the product to be dispensed and their ratio. The maximum diameter of the inner container 2 can be just as large as that of the opening edge 29 of the outer container 1, so that the inner container 2 can still be inserted into the outer container 1 through this opening. These dimensions are standardized for common sizes.

Das im Deckel 30 befestigte Abgabeventil 3 besteht aus einem Ventilkörper 31 und einem in diesem axial einwärts bewegbar gelagerten Betätigungs- oder Abgaberöhrchen 13, durch welches die Mischung aus dem Innenraum des äußeren Behälters 1 entnehmbar ist. Das Abgaberöhrchen 13 ist entgegen der Wirkung einer Schraubenfeder 32 axial einwärts bewegbar, wobei die Abstützung der Schraubenfeder 32 am Ventilkörper 31 einerseits und an einer am Abgaberöhrchen 13 angeformten Ringschulter 33 andererseits erfolgt. Der Ventilkörper 31 ist im Deckel 30 form- und kraftschlüssig verankert, wie Fig. 1 sehr gut erkennen läßt. Am Ventilkörper 31 ist ferner der innere Behälter 2 über eine Abstützung 4 sowohl in axialer als auch radialer bzw. seitlicher Richtung abgestützt. Die Abstützung 4 ist vorzugsweise als ein in axialer Richtung wirkendes Federelement ausgebildet, das den inneren Behälter 2 gegen eine untere Behälterabstützung 5 drückt. Der innere Behälter 2 ist mit einer flaschenhalsartigen Öffnung 20 nach unten gerichtet innerhalb des äußeren Behälters 1 angeordnet. Die flaschenhalsartige Öffnung 20 ist mittels eines Verschlußpfropfens 7 aus Kunststoff, Gummi od.dgl. verschlossen, wobei der Verschlußpfropfen 7 hutförmig ausgebildet und mit seinem äußeren Rand 34 zwischen dem Rand 35 der Öffnung 20 des inneren Behälters 2 und der Behälterabstützung 5 fixiert ist (siehe Fig.2). Der Verschlußpfropfen 7 umfaßt eine die Öffnung 20 verschließende Membran 11, die vorzugsweise etwas dünnwandiger ausgebildet ist als der übrige Teil des Verschlußpfropfens 7 und die bei der dargestellten Ausführungsform durch einen Kerbring 21 zum erleichterten Aufbrechen begrenzt ist. Dadurch wird eine Sollbruchstelle im inneren Verschlußpfropfen 7 erhalten.The dispensing valve 3 fastened in the cover 30 consists of a valve body 31 and an actuating or dispensing tube 13 which is axially movable in this, through which the mixture can be removed from the interior of the outer container 1. The dispensing tube 13 can be moved axially inward against the action of a helical spring 32, the helical spring 32 being supported on the valve body 31 on the one hand and on an annular shoulder 33 formed on the dispensing tube 13 on the other hand. The valve body 31 is anchored in the cover 30 in a positive and non-positive manner, as can be seen very well in FIG. 1. On the valve body 31, the inner container 2 is also abge via a support 4 in both the axial, radial and lateral directions supports. The support 4 is preferably designed as a spring element acting in the axial direction, which presses the inner container 2 against a lower container support 5. The inner container 2 is arranged with a bottle-neck-like opening 20 facing downward inside the outer container 1. The bottle neck-like opening 20 is by means of a plug 7 made of plastic, rubber or the like. closed, the plug 7 being hat-shaped and fixed with its outer edge 34 between the edge 35 of the opening 20 of the inner container 2 and the container support 5 (see FIG. 2). The closure plug 7 comprises a membrane 11 which closes the opening 20 and which is preferably of somewhat thinner wall than the remaining part of the closure plug 7 and which in the embodiment shown is delimited by a notch ring 21 for easier breaking open. As a result, a predetermined breaking point in the inner plug 7 is obtained.

Die Membran 11 ist mittels eines durch den Boden 14 des äußeren Behälters 1 hindurch wirksamen Brechelements unter Herstellung einer Fluidverbindung zwischen dem inneren und äußeren Behälter von außen her aufbrechbar, wobei das Brechelement bei der Ausführungsform nach den Fig. 1 bis 5 durch einen stiftartigen Locher 9 mit etwa kreisförmigem Querschnitt (siehe Fig. 3a und 3b) gebildet ist. Der stift- bzw. bolzenartige Locher 9 ist unter Aufrechterhaltung einer Fluiddichtung zwischen dem Innenraum des äußeren Behälters und der Umgebung durch einen im Boden 14 des äußeren Behälters 1 angeordneten Verschlußpfropfen 8 aus Gummi, Kunststoff od.dgl. korrosionsbeständigem Material, hindurchdrückbar, wie die Fig. 3 und 4 sehr gut erkennen lassen. Der Verschlußpfropfen 8 weist ebenfalls eine dünnwandige und gegebenenfalls durch einen Kerbring begrenzte Membran 22 auf, die durch den Locher 9 bei der Ausführungsform nach den Fig. 3 und 4 aufstoßbar ist. Die Membran 22 befindet sich dabei am behälterinneren Ende einer Axialführung für den Locher 9, die als Sackbohrung 23 ausgebildet ist mit einem Innendurchmesser entsprechend dem Außendurchmesser des Lochers 9. Ferner fluchtet die Membran 22 des äußeren Verschlußpfropfens 8 mit der Membran 11 des inneren Verschlußpfropfens 7. Der Locher 9 weist einen Durchgang für den Austritt der im inneren Behälter 2 befindlichen Komponente B samt Treibgas T aus diesem in den Innenraum des äußeren Behälters 1 auf, und zwar in Form einer Längsnut 12, deren axiale Erstreckung D kleiner ist als die Länge L der Sackbohrung 23 im äußeren Verschlußpfropfen 8. Dadurch ist gewährleistet, daß beim Aufbrechen der Membran 22 des äußeren Verschlußpfropfens 8 keine Komponente A aus dem Innenraum des äußeren Behälters 1 durch die Bohrung 23 austreten kann. Der Zweikammerbehälter wird vorzugsweise in dem in Fig. 2 dargestellten Zustand bereitgestellt. Der Locher 9 ist also in die Bohrung 23 bis zum Anschlag an die Membran 22 eingeschoben. Um beim Transport ein ungewolltes Aufbrechen der Membran 22 zu verhindern, ist eine äußere Schutzkappe 10 vorgesehen, die auf das bodenseitige Ende des äußeren Behälters 1 aufgesetzt bzw. aufgeschoben ist. Die erforderliche Beabstandung der Stirnwand 36 der Schutzkappe 10 vom Boden 14 des äußeren Behälters 1 erfolgt durch innerhalb der Schutzkappe 10 angeordnete, vorzugsweise angeformte, Längsrippen 37.The membrane 11 can be broken open from the outside by means of a breaking element which acts through the bottom 14 of the outer container 1 to produce a fluid connection between the inner and outer container, the breaking element in the embodiment according to FIGS. 1 to 5 being penetrated by a pin-like hole 9 is formed with an approximately circular cross section (see Fig. 3a and 3b). The pin or bolt-like hole 9 is while maintaining a fluid seal between the interior of the outer container and the environment by a plug 8 arranged in the bottom 14 of the outer container 1 made of rubber, plastic or the like. corrosion-resistant material, can be pushed through, as can be seen very well in FIGS. 3 and 4. The plug 8 also has a thin-walled membrane 22, optionally delimited by a notch ring, which can be pushed open through the hole 9 in the embodiment according to FIGS. 3 and 4. The membrane 22 is located on the inside of the container of an axial guide for the hole 9, which is designed as a blind bore 23 with an inner diameter corresponding to the outer diameter of the hole 9. Furthermore, the membrane 22 of the outer plug 8 is aligned with the membrane 11 of the inner plug 7. The hole 9 has a passage for the exit of the component B located in the inner container 2 together with the propellant gas T from it into the interior of the outer container 1, in the form of a longitudinal groove 12, the axial extent D of which is smaller than the length L of the Blind bore 23 in the outer plug 8. This ensures that when the membrane 22 of the outer plug 8 is broken open, no component A can escape from the interior of the outer container 1 through the bore 23. The two-chamber container is preferably provided in the state shown in FIG. 2. The punch 9 is thus inserted into the bore 23 up to the stop on the membrane 22. In order to prevent an undesired breaking of the membrane 22 during transport, an outer protective cap 10 is provided, which is placed or pushed onto the bottom end of the outer container 1. The required spacing of the end wall 36 of the protective cap 10 from the bottom 14 of the outer container 1 is achieved by means of longitudinal ribs 37 arranged, preferably integrally formed, within the protective cap 10.

Der innere Behälter 2 ist im Bodenbereich des äußeren Behälters 1 am äußeren Verschlußpfropfen 8 sowohl axial als auch seitlich abgestützt, und zwar über das Stützelement 5, das eine topfförmige Aufnahme 38 für den unteren Teil des inneren Behälters 2 sowie mit dem in das Behälterinnere ragenden Teil des Verschlußpfropfens 8 zusammenwirkende Zentrierrippen 6 aufweist, wobei mindestens drei gleichmäßig über dem Umfang verteilt angeordnete Zentrierrippen 6 vorgesehen sind. Zum erleichterten Eindrücken des Lochers 9 ist dieser an seinem aus dem äußeren Behälter 1 bzw. dem äußeren Verschlußpfropfen 8 herausragenden Ende mit einer Druckplatte 39 versehen.The inner container 2 is supported in the bottom region of the outer container 1 on the outer plug 8 both axially and laterally, namely via the support element 5, which has a cup-shaped receptacle 38 for the lower part of the inner container 2 and with the part projecting into the interior of the container of the closure plug 8 has cooperating centering ribs 6, at least three centering ribs 6 being provided distributed uniformly over the circumference. To make it easier to press the hole 9 in, it is provided with a pressure plate 39 at its end protruding from the outer container 1 or the outer plug 8.

In Fig. 4 ist der Locher im vollständig eingedrückten Zustand dargestellt. Sowohl die Membran 22 des äußeren Verschlußpfropfens 8 als auch die Membran 11 des inneren Verschlußpfropfens 7 sind aufgebrochen. Durch die Längsnut 12 kann die Füllgutkomponente B aus dem Inneren des inneren Behälters 2 in den Innenraum des äußeren Behälters 1 austreten (siehe Pfeile 40) und sich mit der Komponente A vermischen.In Fig. 4 the punch is shown in the fully pressed state. Both the membrane 22 of the outer plug 8 and the membrane 11 of the inner plug 7 are broken. Through the longitudinal groove 12, the filling component B can emerge from the interior of the inner container 2 into the interior of the outer container 1 (see arrows 40) and mix with the component A.

Vorzugsweise ist der Verschlußpfropfen 7 des inneren Behälters integraler Bestandteil der unteren Abstützung 5, d.h. Verschlußpfropfen 7 und Abstützung 5 bilden ein einstückiges Bauteil. Ferner kann das behälterinnere Ende des Lochers 9 etwas angespitzt ausgeführt sein zum erleichterten Aufbrechen sowohl der Membran 22 als auch der Membran 11.Preferably, the plug 7 of the inner container is an integral part of the lower support 5, i.e. Sealing plug 7 and support 5 form a one-piece component.
