Description
Vorrichtung zur Abgabe eines Wirkstoffes in normaler-weise geschlossenen, jedoch zu öffnende Räume Zusatz zu Patent................ Device for the delivery of an active ingredient in normally closed, However, rooms that can be opened Addition to patent ................
(Patentanmeldung P 20 54 219.2) Die Erfindung betrifft eine Vorrichtung zur Abgabe eines Wirkstoffes z. B. eines Desodorants, eines parftimierenden Mittels, eines Insektizids oder dergl. in normalerweise geschlossene, jedoch mit einem eine Verbindung mit der Umgebung ermöglichenden Offnungsteil, wie z. B. einer Tür, Klappe oder dergl. versehene Räume, beispielsweise Toiletten, Badezimmer, Schränke u.s.w. (Patent application P 20 54 219.2) The invention relates to a device for the delivery of an active ingredient z. B. a deodorant, a perfuming agent, an insecticide or the like. In normally closed, but with a one Connection with the environment enabling opening part, such. B. a door, flap or the like. Provided rooms, for example toilets, bathrooms, cupboards, etc.
Nach dem Hauptpatent erfolgt zwecks Erzielung einer der Häufigkeit des öffnens und Schliessens des Raumes proportionalen Abgabe des Wirkstoffes die Betätigung des Abgabeorgans des Wirkstofftehälters, der an dem Üffnungsteil befestigt ist, durch eine ebenfalls an dem dffnungsteil schwenkbar angelenkte Sehwungmasse. Dadurch wird infolge der Trägheit der Schwungmasse bei jedem oeffnen und Schliessen des Öffnungteils, d. h. der TUr, Klappe oder dergl., eine nahezu gleichbleibende Menge des Wirkstoffes abgegeben, so daß sich die Konzentration des Wirkstoffes im Inneren des betreffenden Raumes im Laufe der Zeit nicht erhöht, da ja die Zugabe von Wirkstoffen der Häufigkeit der Offnung und damit der Benutzung und Belüftung durch das öffnungsteil proportional ist. Beispielsweise erfolgt bei einer nach außen zu öffnenden Schranktür eine Abgabe aus dem Wirkstoffbehälter, und auch beim Schließen des Schranktür wiederholt sich dieser Abgabevorgang, normalerweise sowohl zu Beginn der Schließbewegung als auch bei der plötzlichen Verzögerung bei Erreichen der Schließstellung der Tür. Bei einer Teilettentür, die nach innen zu öffnen ist, folgen die Vorgänge in umgekehrter Richtung, d. h. die plötzliche Beschleunigung der Vorrichtung beim öffnen der Tür löst einen Wirkstoff-Abgabevorgang aus, und ebenso die plötzliche Verzögerung beim darauffolgenden Schließen der Tür.According to the main patent, one of the frequencies is used for the purpose of obtaining the opening and closing of the space proportional release of the active ingredient Actuation of the dispensing member of the drug container, which is attached to the opening part is, by means of a rotating mass which is also pivotably linked to the opening part. As a result of the inertia of the flywheel it opens and closes each time the opening part, d. H. the door, Flap or the like., An almost constant amount of the active ingredient released, so that the concentration of the Active ingredient in the interior of the room in question does not increase over time, because yes the addition of active ingredients depending on the frequency of opening and thus of use and ventilation through the opening part is proportional. For example, takes place at a cabinet door that can be opened to the outside, a delivery from the agent container, and this dispensing process is also repeated when the cabinet door is closed, normally both at the beginning of the closing movement and during the sudden deceleration The door is in the closed position. With a partial door that closes inwards is open, the operations follow in the reverse direction, i. H. the sudden acceleration the device when the door is opened triggers an active ingredient release process, and likewise the sudden delay in the subsequent closing of the door.
Im Hauptpatent ist bereits angegeben, daß als Wirkstoffbehälter beispielsweise Aerosolbehälter mit einem Sprühventil als Abgabeorgan in Frage kommen.In the main patent it is already indicated that, for example, as an active ingredient container Aerosol containers with a spray valve can be used as the delivery device.
In der Praxis hat sich nun gezeigt, daß in manchen Anwendungsfällen, beispielsweise bei Anbringung einer Vorrichtung nach dem Hauptpatent an der Toilettentür einer dreiköpfiger Familie, der Inhalt des Wirkstoffbehälters, also im allgemeinen einer Aerosolflasche, zu schnell, beispielsweise etwa nach einer Woche erschöpft sein kann, Daraus läßt sich der Schluß ziehen, daß bei jeder Betätigung aus dem Aerosolbehälter zu viel Wirkstoff mit treibgas austritt. Auf mechanische Art und Weise läßt sich dies nicht oder allenfalls nur schwierig verhindern.In practice it has now been shown that in some applications, for example when attaching a device according to the main patent to the toilet door a family of three, the contents of the drug container, so in general an aerosol bottle, too quickly, for example after about a week exhausted can be, From this the conclusion can be drawn that with every actuation from the Aerosol container too much active substance leaking with propellant gas. In a mechanical way and In this way, this cannot be prevented, or at best only with difficulty.
Aufgabe der Erfindung ist es, diese in manchen Anwendungsfällen auftretenden Probleme bei der Benutzung des Gegenstands des Hauptpatents zu vermeiden.The object of the invention is to remedy this that occurs in some applications To avoid problems when using the subject matter of the main patent.
Die Erfindung beruht auf der Überlegung, daß dafür gesorgt werden muß, daß nur noch gasförmiges Gemisch aus der Aerosolflasche austritt. Dadurch wird die bei jeder Betätigung austretende Menge erheblich herabgesetzt gegenüber einer Ausführungsform, bei der der Wirkstoff in flüssiger Form, selbst bei feinster Spriihverteilung, austritt. Dementsprechend wird die gestellte Aufgabe dadurch gelöst, daß als Wirkstoffbehälter ein Aerosolbehälter vorgesehen ist, der ein Azeotrop enthält, d. h. eine Mischung von Wirkstoff und Treibmittel, bei der das Mischungsverhältnis zwischen Wirkstoff und Treibmittel in der Flüssigkeitsphase genau gleich ist dem Mischungsverhältnis in dem sich bildenden Gas in dem Behälter, und daß die Entnahme des Behälterinhalts nicht, wie bisher bei allen Aerosolbehältern üblich, aus dem Flüssigkeitsraum des Behälters erfolgt, sondern vielmehr aus dem Gasraum. Dies wird in der Weise verwirklicht, daß im Falle der Verwendung eines Behälters mit abwärtsgerichteter Entnahmevorrichtung ein bis in den Gasraum reichendes Steigröhrchen vorhanden ist, während bei Verwendung eines Behälters mit nach oben gerichteter Entnahmevorrichtung diese direkt mit dem obenliegenden Gasraum des Behälters verbunden ist. Die Anordnung wird also genau umgekehrt getroffen, wie bei bisher bekannten Aerosolbehältern, die ja bei obenliegender Entnahmevorrichtung ein bis zum Boden des Behälters, d. h. also bis zum unteren Ende des Flüssigkeitsraums reichendes Steigröhrchen aufweisen.The invention is based on the idea that this should be taken care of must that only a gaseous mixture emerges from the aerosol bottle. This will the amount escaping with each actuation is considerably reduced compared to a Embodiment in which the active ingredient in liquid form, even with the finest spray distribution, exit. Accordingly, the object is achieved in that as an active ingredient container an aerosol container is provided which contains an azeotrope, d. H. a mixture of active ingredient and propellant, in which the mixing ratio between active ingredient and propellant in the liquid phase is exactly the same as the mixing ratio in the gas that forms in the container, and that the contents of the container are removed not, as was previously the case with all aerosol containers, from the liquid space of the Container takes place, but rather from the gas space. This is done in the way that in the case of using a container with a downward-facing Extraction device a riser tube reaching into the gas space is available while in use a container with upward removal device this directly with the overhead gas space of the container is connected. So the arrangement will be accurate taken the other way around, as with previously known aerosol containers, which are yes with the overhead Removal device one to the bottom of the container, d. H. so down to the bottom Have riser tube reaching the end of the liquid space.
