Abstract

A device for applying cosmetic or pharmaceutical medium consists of a cylindrical body (3) which contains the liquid medium. The body is connected to a balloon (5) made from flexible material. When the balloon is compressed, air is driven into the body and causes an atomised stream of a mixture of air and medium to be ejected through the nozzle (20). The body (3) is initially provided with a cover (40) which is torn away before the device is used in order to expose the nozzle (20).

Description

Die Erfindung betrifft eine Austragvorrichtung nach dem Oberbegriff des Patentanspruches 1. Sie soll insbesondere zur Feinstzerstäubung flüssiger, pulverförmiger oder ähnlicher Medien sowie zum handgetragenen Gebrauch und zur einhändigen Bedienung geeignet sein.The invention relates to a discharge device according to the preamble of claim 1. It should be particularly suitable for fine atomization of liquid, powdery or similar media, as well as for hand-held use and for one-handed operation.

Die Austragvorrichtung kann eine, ein Treibfluid fördernde Treibpumpe aufweisen, mit welchem das Medium aus einer oder mehreren Medienkammern bzw. -speichern in Richtung zu einer oder mehreren Auslaßöffnungen dadurch ausgetrieben wird, daß das Volumen einer oder mehrerer Druckkammern verändert bzw. verringert wird. Obwohl das in der Druckkammer befindliche Medium das gleiche bzw. von gleichem Aggregatzustand wie das in der Medienkammer befindliche Medium sein kann, unterscheiden sich diese Medien zweckmäßig hinsichtlich des Aggregatzustandes, wobei das Treibmedium vorteilhaft ein geeignetes Gas, z.B. Luft, ist, während das getriebene Medium, nämlich z.B. ein pharmazeutischer oder kosmetischer Wirkstoff, wenigstens teilweise flüssig und/oder pulverförmig ist.The discharge device can have a propellant pump which delivers a propellant fluid and with which the medium is expelled from one or more media chambers or stores in the direction of one or more outlet openings by changing or reducing the volume of one or more pressure chambers. Although the medium in the pressure chamber can be the same or of the same state of aggregation as the medium in the media chamber, these media expediently differ with regard to the state of aggregation, the propellant advantageously being a suitable gas, for example air, while the driven medium , namely, for example, a pharmaceutical or cosmetic active ingredient, is at least partially liquid and / or powdery.

Statt einer chemischen Zuordnung des Treibmediums und des Wirkmediums so, daß diese bei Durchmischung chemisch reagieren, ist zweckmäßig die Ausbildung so vorgesehen, daß diese Medien miteinander chemisch nicht reagieren, sondern lediglich Mischungen bilden können. Zweckmäßig ist das je Arbeitshub auszubringende Volumen des Treibmediums um eine bis drei Potenzen größer als das Volumen des während dieses Arbeitshubes auszubringenden Wirkstoffes, wobei das jeweilige Volumen im wesentlichen dem gesamten Speichervolumen der Druckkammer bzw. der Medienkammer entsprechen kann, die beim jeweiligen Arbeitshub nahezu vollständig entleert werden. Durch diese erfindungsgemäßen Ausbildungen wird eine sehr vorteilhaft zu handhabende Austragvorrichtung geschaffen.Instead of chemically assigning the propellant and the active medium so that they react chemically when mixed, the design is expediently provided in such a way that these media do not react chemically with one another, but can only form mixtures. The volume of the propellant to be discharged per working stroke is expediently one to three potencies larger than the volume of the active ingredient to be discharged during this working stroke, the respective volume being able to correspond essentially to the total storage volume of the pressure chamber or the media chamber, which is almost completely emptied during the respective working stroke will. These designs according to the invention create a discharge device which can be handled very advantageously.

Die DE-A-3 446 466 zeigt ein Inhaliergerät mit einer Medienkammer, aus welcher das vernebelte Medium abzuatmen ist. Innerhalb des Gehäusekörpers der Medienkammer liegende Bauteile dienen zur Erzeugung des Nebels.DE-A-3 446 466 shows an inhaler with a media chamber from which the atomized medium is to be exhaled. Components lying inside the housing body of the media chamber serve to generate the mist.

Die WO-A-91/12 895 zeigt eine Austragvorrichtung, bei welcher innen liegende Bauteile ebenfalls nicht bis an eine von der Auslaßöffnung durchsetzte Stirnwand reichen oder zugehörige Querkanäle begrenzen.WO-A-91/12 895 shows a discharge device in which internal components likewise do not extend as far as an end wall through which the outlet opening extends or limit associated transverse channels.

Der Erfindung liegt die Aufgabe zugrunde, eine Austragvorrichtung der genannten Art zu schaffen, bei welcher Nachteile bekannter Austragvorrichtungen vermieden sind und die es insbesondere ermöglichen, bei sehr einfachem Aufbau kleinste Wirkstoffmengen feinstverteilt auszutragen.The invention has for its object to provide a discharge device of the type mentioned, in which disadvantages of known discharge devices are avoided and which make it possible, in particular, to discharge the smallest amounts of active substance with very simple construction.

Gemäß der Erfindung sind die Merkmale nach Patentanspruch 1 vorgesehen. Des weiteren kann mindestens eine Treibpumpe als Balgpumpe ausgebildet sein, die unter Zwischenschaltung wenigstens eines Teiles mindestens einer Medienkammer an wenigstens eine Auslaßöffnung angeschlossen ist. Ein von der Treibpumpe gefördertes Treibmedium kann nicht nur zu einer wirksamen Entleerung der Medienkammer, sondern auch dazu führen, daß der Wirkstoff der Medienkammer bereits vor dem Austrag in einem Treibmittelstrom fein verteilt und erst dann mit diesem entlang eines Auslaßkanales und durch eine Auslaßöffnung, z.B. eine Zerstäuberdüse, nach außen gefördert wird.According to the invention, the features according to claim 1 are provided. Furthermore, at least one drive pump can be designed as a bellows pump, which is connected to at least one outlet opening with the interposition of at least part of at least one media chamber. A propellant pumped by the propellant pump can not only lead to an effective emptying of the media chamber, but also to the fact that the active ingredient of the media chamber is finely distributed in a propellant stream before it is discharged and only then along with it along an outlet channel and through an outlet opening, e.g. Atomizer nozzle, is conveyed to the outside.

Durch die erfindungsgemäße Ausbildung können Wirkstoffmengen von z.B. weniger als einem Zehntel oder einem Dreißigstel Kubikzentimeter mit einem mehr als 100fach größeren Treibmittelvolumen von z.B. etwa 5 cm3 feinstverteilt aufgebracht werden.Through the inventive design, amounts of active ingredient of, for example, less than a tenth or a thirtieth of a cubic centimeter can be applied with a more than 100 times larger propellant volume of, for example, about 5 cm 3 .

Es ist denkbar, die Treibmittelpumpe so auszubilden, daß ihre Druckkammer nach einer ersten Entleerung, z.B. über ein Einlaßventil, wieder nachgefüllt werden kann, jedoch ist vorteilhaft wenigstens eine Druckkammer der Treibmittelpumpe bzw. die gesamte Austragvorrichtung lediglich für den einmaligen Gebrauch oder einen einzigen Austragvorgang ausgebildet. Dadurch kann die jeweilige Druckkammer in ihrem Ausgangszustand vollständig geschlossen und ggf. unter Überdruck prall gespannt gefüllt sein, wodurch bei kleinen Abmessungen ein verhältnismäßig großes und in seiner Zusammensetzung bzw. seinem Reinheitsgrad genau bestimmbares Treibmittelvolumen zur Verfügung steht.It is conceivable to design the propellant pump so that its pressure chamber after a first emptying, e.g. Can be refilled via an inlet valve, but at least one pressure chamber of the propellant pump or the entire discharge device is advantageously designed only for single use or a single discharge process. As a result, the respective pressure chamber can be completely closed in its initial state and, if necessary, be filled under tense pressure, so that, with small dimensions, a relatively large propellant volume is available which can be precisely determined in terms of its composition or degree of purity.

Das Treibmittelvolumen kann vorteilhaft nur unter Überwindung des Widerstandes eines den Auslaß der Druckkammer sperrenden Verschlusses aus der Druckkammer herausgedrückt werden, so daß es während der gesamten Lagerzeit der Austragvorrichtung sicher eingeschlossen ist und nicht allmählich entweichen kann. Dieser Verschluß kann im wesentlichen durch das Wirkmedium selbst gebildet sein, wenn die Medienkammer einen Abschnitt des Auslaßkanales der Druckkammer bildet und das Medium die Medienkammer im wesentlichen dicht verschließt bzw. als dichte Packung voll ausfüllt. Dadurch ist nicht, wie auch denkbar, zwischen dem Auslaß der Druckkammer und dem Einlaß der Medienkammer ein z.B. druckabhängig arbeitendes bzw. öffnendes Einlaßventil erforderlich, sondern der Einlaß der Medienkammer ist zum Druckraum der Treibmittelpumpe stets offen. Das auslaßseitige, der Auslaßöffnung zugehörige Ende der Medienkammer bzw. ein daran anschließender Abschnitt des Auslaßkanales kann jedoch mit einem ggf. druckabhängig arbeitenden bzw. öffnenden Verschluß verschlossen sein, welcher sowohl die Druckkammer als auch die Medienkammer gegen unbeabsichtigtes Entleeren sichert und nur beim bestimmungsgemäßen Gebrauch geöffnet ist.The propellant volume can advantageously be pressed out of the pressure chamber only by overcoming the resistance of a closure blocking the outlet of the pressure chamber, so that it is securely enclosed during the entire storage period of the discharge device and cannot escape gradually. This closure can essentially be formed by the active medium itself if the media chamber forms a section of the outlet channel of the pressure chamber and the medium closes the media chamber essentially tightly or completely fills it as a tight packing. As a result, it is not, as is also conceivable, a pressure-dependent, for example, between the outlet of the pressure chamber and the inlet of the media chamber working or opening inlet valve required, but the inlet of the media chamber is always open to the pressure chamber of the propellant pump. However, the outlet-side end of the media chamber belonging to the outlet opening or a section of the outlet channel adjoining it can be closed with an optionally pressure-dependent working or opening closure, which secures both the pressure chamber and the media chamber against unintentional emptying and only opens when used as intended is.

Erfindungsgemäß ist des weiteren ein die Auslaßöffnung und/oder die Medienkammer aufweisendes, im wesentlichen formstabiles Gehäuse vorgesehen, das zweckmäßig mit der Treibmittelpumpe bzw. mit voneinander abgekehrten Druck-Handhaben zur Austragbetätigung um mindestens eine zu seiner Mittelachse bzw. der Mittelachse der Auslaßöffnung querliegende und vorzugsweise diese Mittelachse rechtwinklig schneidende Gelenkachse gelenkig verbunden ist. Dadurch kann das Gehäuse zur Vereinfachung der Handhabung beim Austrag und/oder zur Erzielung eines kompakten Lagerzustandes in unterschiedlichen Winkellagen gegenüber den genannten Bauteilen ausgerichtet werden. Bevorzugt ist eine Schwenkbewegung im wesentlichen nur um eine einzige definierte Gelenkachse möglich, welche zwei von ihr frei abstehende Gliederabschnitte der Austragvorrichtung verbindet und quer zur Betätigungsrichtung der Handhaben liegt.According to the invention, a substantially dimensionally stable housing is also provided which has the outlet opening and / or the media chamber and which is expediently used with the propellant pump or with pressure handles turned away from one another for discharge actuation by at least one which is transverse and preferably transverse to its central axis or the central axis of the outlet opening this central axis is articulated and intersects at right angles. As a result, the housing can be aligned in different angular positions with respect to the named components in order to simplify handling during discharge and / or to achieve a compact storage condition. Preferably, a pivoting movement is essentially only possible about a single defined hinge axis, which connects two limb sections of the discharge device which project freely therefrom and is transverse to the direction of actuation of the handles.

Die Treibmittelpumpe ist zweckmäßig durch einen freiliegenden, kissenförmigen Balg aus aufeinanderliegenden und am Umfang der Druckkammer in Randbereichen dicht verbundenen Folien gebildet, von denen im Abstand benachbart zur Außenseite des Druckraumes auch das Gehäuse wenigstens teilweise eingeschlossen sein kann, so daß die Folienteile die einzige Verbindung zwischen dem Gehäuse und dem Druckraum herstellen. Die beiden ballig gewölbten und im wesentlichen in einer gemeinsamen Verbindungsebene auslaufenden, gleich großen Wandungen des Druckraumes können mit ihren Außenseiten unmittelbar sowie mit ihrer gesamten Fläche die Handhaben zur Betätigung der Austragvorrichtung bilden und haben vorteilhaft eine Flächengröße etwa in der Größenordnung eines Daumenballens, so daß eine ergonomisch sehr günstige Handhabung zur annähernd vollständigen Entleerung der Druckkammer unter hohem Druck gewährleistet ist.The propellant pump is expediently formed by an exposed, pillow-shaped bellows made of foils lying one on top of the other and tightly connected at the periphery of the pressure chamber in edge regions, at least the housing of which is at a distance adjacent to the outside of the pressure chamber can be partially enclosed so that the film parts make the only connection between the housing and the pressure chamber. The two crowned and essentially the same size walls of the pressure chamber, which run out in a common connection plane, can directly and with their entire surface form the handles for actuating the discharge device and advantageously have a surface area of approximately the size of a ball of thumb, so that a Ergonomically very favorable handling for almost complete emptying of the pressure chamber under high pressure is guaranteed.

Mehrere Einzel-Austragvorrichtungen können zerstörungsfrei oder unter Zerstörung der Verbindung mit einem gemeinsamen Träger verbunden sein, an dem die Einzel-Austragvorrichtungen zweckmäßig in einer einzigen Reihe oder in einem mehrreihigen Raster hinter- oder nebeneinander angeordnet sind, wobei sie in dieser Verbindung zweckmäßig so stehen, daß Handhaben benachbarter Austragvorrichtungen nicht einander zugekehrt sind, sondern wie die Gelenkachsen in gleicher Ausrichtung etwa in einer gemeinsamen Ebene liegen. Der Träger oder ein gesonderter Bauteil kann auch gleichzeitig einen Verschluß der Auslaßöffnung bilden, so daß diese erst freigegeben ist, wenn der Verschluß durch manuelles Greifen und Öffnen entfernt ist.Several individual discharge devices can be connected non-destructively or by destroying the connection to a common carrier on which the individual discharge devices are expediently arranged in a single row or in a multi-row grid, one behind the other or next to one another, in which connection they are expediently such that that handling of adjacent discharge devices are not facing each other, but, like the hinge axes, lie approximately in the same orientation in a common plane. The carrier or a separate component can also form a closure of the outlet opening at the same time, so that it is only released when the closure is removed by manual gripping and opening.

Diese und weitere Merkmale gehen außer aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei einer Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen können, für die hier Schutz beansprucht wird. Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher erläutert. In den Zeichnungen zeigen:

These and other features emerge from the claims and also from the description and the drawings, the individual features being realized individually and in groups in the form of sub-combinations in one embodiment of the invention and in other fields, and being advantageous and Protectable versions can be represented, for which protection is claimed here. An embodiment of the invention is shown in the drawings and is explained in more detail below. The drawings show:
Fig. 1
a discharge device designed as a set in view,
Fig. 2
a section of a single discharge device according to FIG. 1 in a substantially enlarged and sectional view and
Fig. 3
a cross section through the formation of FIG. 1 in a substantially enlarged view.

Das Austrag-Set 1 gemäß Fig. 1 weist eine Vielzahl gleicher oder ungleicher Austragvorrichtungen 2 auf, die unabhängig voneinander entnommen und zwangsläufig erst dann so betätigt werden können, daß ein Medienaustrag erfolgt. Die Austragvorrichtungen 2 können gleiche oder unterschiedliche Größe bzw. Füllvolumen oder Füllstoffe haben, je nachdem für welche Art von Anwendung das Set 1 vorgesehen ist. Die Austragvorrichtungen 2 liegen in einer geraden Reihe hintereinander, könnten aber auch in einem Ring bzw. Kranz oder ähnlichem vorgesehen sein. Zumindest Teile benachbarter Austragvorrichtungen 2 sind auch im Set 1, insbesondere quer zu ihrer Verbindungsgeraden bzw. ihrer gemeinsamen Ebene gegeneinander frei bewegbar, wobei benachbarte Austragvorrichtungen 2 einander nicht berühren, sondern über Spaltlücken vollständig im Abstand voneinander liegen und lediglich an einer einzigen Seite bzw. Stirnfläche mit einem gemeinsamen Träger verbunden sind, von dem sie frei abstehen.The discharge set 1 according to FIG. 1 has a large number of identical or different discharge devices 2, which can be removed independently of one another and can only be actuated in such a way that a media discharge takes place. The discharge devices 2 can have the same or different sizes or fill volumes or fillers, depending on the type of application for which the set 1 is intended. The discharge devices 2 lie in a straight row one behind the other, but could also be provided in a ring or ring or the like. At least parts of adjacent discharge devices 2 can also be moved freely in the set 1, in particular transversely to their connecting straight line or their common plane, with adjacent discharge devices 2 not touching one another, but being completely spaced apart from one another via gap gaps and merely on a single side or end face are connected to a common support from which they protrude freely.

Die jeweilige Austragvorrichtung 2 weist ein formstabiles, langgestrecktes Gehäuse 3 auf, dessen Außenumfang im wesentlichen über seine gesamte Länge durchgehend kontinuierlich glattflächig bzw. zylindrisch ausgebildet ist. Das Gehäuse 3 liegt am Ende eines gegenüber ihm in der Breite, der Dicke und der Länge größeren Griffes 4, der im wesentlichen aus biegeschlaffem flexiblem Werkstoff besteht, im wesentlichen allseits über die Hüllfläche des Gehäuses 3 vorsteht und mit diesem über eine wenigstens teilweise biegeschlaffe Verbindung verbunden ist. Der Griff 4 dient zum Halten sowie zur Betätigung der Austragvorrichtung 2 während des Gebrauches, wobei dann das Gehäuse 3 gegenüber dem Griff nicht in seiner Längsrichtung aber quer dazu frei beweglich ist. Im Set 1 sind die Gehäuse 3 zwar gegeneinander nicht beweglich, jedoch die Griffe 4 der Austragvorrichtungen 2, so daß sie sich zur Trennung leicht greifen und in die günstigste Stellung bringen lassen.The respective discharge device 2 has a dimensionally stable, elongated housing 3, the outer circumference of which is essentially continuously smooth or cylindrical over its entire length. The housing 3 is located at the end of a handle 4 which is larger in terms of width, thickness and length and which essentially consists of flexible, flexible material, essentially projects beyond the envelope surface of the housing 3 on all sides and with it via an at least partially flexible connection connected is. The handle 4 serves to hold and to actuate the discharge device 2 during use, the housing 3 then being freely movable with respect to the handle in its longitudinal direction but transversely thereto. In set 1, the housings 3 are not movable relative to one another, but the handles 4 of the discharge devices 2, so that they can be easily gripped for separation and brought into the most favorable position.

Die Austragvorrichtung 2 weist eine im wesentlichen durch den Griff 4 gebildete bzw. innerhalb von diesem liegende Gaspumpe 5 in Form einer Balgpumpe auf, die keinen Faltenbalg hat. Der kissenförmige bzw. in allen Querschnitten annähernd flachovale Druckraum 6 der Gaspumpe 5 ist von zwei einander gegenüberliegenden, ballig nach außen gekrümmten Wandungen 7, 8 aus biegeschlaffer bzw. im wesentlichen zugunelastischer Folie gebildet, die z.B. unter den gebrauchsbedingt auftretenden Belastungen nicht mehr als zwei, fünf oder zehn Prozent gedehnt werden kann. Die beiden Folienbereiche, die durch Faltung einteilig miteinander ausgebildet oder durch gesonderte, aufeinandergelegte Folienteile gebildet sein können, liegen im Anschluß an den Außenumfang des Druckraumes 6 im Bereich eines Randes 9 aneinander an und sind in diesem Bereich ganzflächig haftend, z.B. durch Schweißung, miteinander verbunden, so daß der Druckraum 6 nach außen dicht abgeschlossen ist. Der Druckraum 6 liegt, wie im wesentlichen alle übrigen Bestandteile der Austragvorrichtung, symmetrisch zu einer Mittelachse 10 und mit einem gegenüber der Weite des Gehäuses 3 wesentlich geringerem Abstand vom zugehörigen Ende dieses Gehäuses 3.The discharge device 2 has a gas pump 5, essentially formed by the handle 4 or lying within it, in the form of a bellows pump which has no bellows. The cushion-shaped pressure chamber 6 of the gas pump 5, which is approximately flat in all cross-sections, is formed by two opposing, spherically curved walls 7, 8 made of flexible or substantially inelastic film which, for example, does not exceed two under the loads occurring due to use. can be stretched five or ten percent. The two film areas, which are formed in one piece by folding or can be formed by separate, superimposed film parts, are adjacent to the outer periphery of the pressure chamber 6 in the region of an edge 9 and are adhered to each other in this area, for example by welding, so that the pressure chamber 6 is sealed to the outside . The pressure chamber 6, like essentially all the other components of the discharge device, is symmetrical to a central axis 10 and at a distance from the associated end of this housing 3 that is substantially smaller than the width of the housing 3.

Der Druckraum 6 bzw. der zugehörige Folienballon schließt über einen in der Breite und Dicke wesentlich verengten Hals 11 an das zugehörige Ende des Gehäuses 3 an. Dieser Hals 11 hat quer zur Mittelachse 10 langgestreckte, über seine Länge im wesentlichen konstante Flachquerschnitte, wobei seine Länge kleiner als die größere Querschnittserstreckung und größer als die kleinere Querschnittserstreckung ist. Der Hals 11 begrenzt einen seinen Abmessungen entsprechenden Auslaßkanal 12 und ist ebenfalls durch die Folienabschnitte 13, 14 gebildet, welche auch die Wandungen 7, 8 des Druckraumes 6 bilden.The pressure chamber 6 or the associated foil balloon connects to the associated end of the housing 3 via a neck 11 which is substantially narrow in width and thickness. This neck 11 has transversely to the central axis 10 elongated, essentially constant flat cross sections over its length, its length being smaller than the larger cross-sectional extent and greater than the smaller cross-sectional extent. The neck 11 delimits an outlet duct 12 corresponding to its dimensions and is also formed by the film sections 13, 14, which also form the walls 7, 8 of the pressure chamber 6.

Diese Folienabschnitte 13, 14 bilden im Bereich der Wandungen 7, 8 auch die voneinander abgekehrten und nach außen ballig gewölbten Handhaben 15, 16, die zur Ingangsetzung bzw. Durchführung der Austragbetätigung zwischen zwei oder drei Fingern einer Hand so gegeneinander zu drücken sind, daß dadurch der Druckraum 6 flachgedrückt und über den Auslaßkanal 12 in das Gehäuse 3 entleert wird. Die Druckkammer 6 hat somit herstellerseitig eine unter Überdruck dicht eingeschlossene Originalfüllung, welche die biegeschlaffen Handhaben 5, 16 sowie den Hals 11 in ihrer gespannten Ausgangslage, z.B. pneumatisch, rückfedernd sichert, wobei die Gaspumpe 5 nur eine einzige Entleerung der Druckkammer 6 ohne darauffolgende Wiederfüllung zuläßt.These film sections 13, 14 form in the region of the walls 7, 8 also the handles 15, 16 which face away from one another and are convexly curved outwards, and which are to be pressed against one another in order to initiate or carry out the discharge operation between two or three fingers of the hand in such a way that thereby the pressure chamber 6 is flattened and emptied into the housing 3 via the outlet channel 12. The pressure chamber 6 thus has an original filling sealed tightly under excess pressure by the manufacturer, which resiliently secures the pliable handles 5, 16 and the neck 11 in their tensioned starting position, for example pneumatically, the gas pump 5 only permitting a single emptying of the pressure chamber 6 without subsequent refilling.

Das Gehäuse 3 ist nur aus zwei einteiligen Bauteilen, nämlich einem äußeren Gehäusekörper 17 und einem im wesentlichen bzw. vollständig in diesem liegenden Gehäusekern 18 gebildet, wobei das Gehäuse 3 ohne Verwendung gesonderter Verbindungsglieder unmittelbar mit dem Griff 4 bzw. den Wandungen 7, 8 der Druckkammer 6 verbunden ist. Der äußere Gehäusekörper 17 ist an einem Ende mit einer Stirnwand 19 im wesentlichen verschlossen und am anderen Ende im wesentlichen auf seiner vollen, übrigen Innenweite offen. Im Zentrum ist die Stirnwand 19 von einer an ihrer Außenseite liegenden Auslaßöffnung 20 einer Zerstäuber-Düse 21 durchsetzt. Die Auslaßöffnung 20 liegt im Bereich der tiefsten Stelle einer vertieften Düsenkuhle 22, welche in der Außenseite der Stirnwand 19 vorgesehen ist, gegenüber der Auslaßöffnung 20 eine wesentlich größere Weite hat und von einer annähernd ebenen Ringfläche der Stirnwand 19 umgeben ist.The housing 3 is formed only from two one-piece components, namely an outer housing body 17 and a housing core 18 lying essentially or completely therein, the housing 3 being directly connected to the handle 4 or the walls 7, 8 without the use of separate connecting members Pressure chamber 6 is connected. The outer housing body 17 is essentially closed at one end with an end wall 19 and at the other end essentially open over its full, remaining inner width. In the center, the end wall 19 is penetrated by an outlet opening 20 of an atomizer nozzle 21 located on its outside. The outlet opening 20 is in the region of the deepest point of a recessed nozzle cavity 22, which is provided in the outside of the end wall 19, has a substantially larger width than the outlet opening 20 and is surrounded by an approximately flat annular surface of the end wall 19.

Der gegenüber der Innenweite des Gehäusekörpers 17 engere Gehäusekern 18 ist von der offenen Seite des Gehäusekörpers 17 her in eine Zentrierung 23 eingesetzt, welche nur im Bereich des der Stirnwand 19 zugehörigen Endes des Gehäusekernes 18 bzw. in einem Abstand von dessen anderem Ende liegt, der größer als das ein- oder zweifache seines Außendurchmessers ist. Die Zentrierung 23 kann z.B. durch einteilig mit dem Gehäusekörper 17 und/oder dem Gehäusekern 18 ausgebildete Radial- bzw. Längsrippen gebildet sein, welche über den Innenumfang des Gehäusekörpers 17 und den Außenumfang des Gehäusekerns 18 vorstehen sowie diese beiden Bauteile durch Preßsitz axial und/oder in Drehrichtung festsitzend miteinander verbinden. Die zugehörige Stirnseite 24 des dornförmig im wesentlichen über seine gesamte Länge konstante Außenweite aufweisenden Gehäusekernes 18 liegt zweckmäßig an der Innenseite der Stirnwand 19 anschlagbegrenzt an. Im Bereich dieser Stirnseiten ist eine der Düse 21 zugehörige Dralleinrichtung 25 vorgesehen, welche die Medienmischung beim Eintritt in einen gegenüber der Auslaßöffnung 20 erweiterten Abschnitt des Düsenkanales in Rotation um die Mittelachse 10 dadurch versetzt, daß zwischen den Stirnseiten Querkanäle gebildet sind, welche etwa tangential in die Düse 21 münden.The housing core 18, which is narrower than the inside width of the housing body 17, is inserted from the open side of the housing body 17 into a centering 23, which lies only in the region of the end of the housing core 18 associated with the end wall 19 or at a distance from the other end thereof is larger than one or two times its outer diameter. The centering 23 can be formed, for example, by radial or longitudinal ribs which are formed in one piece with the housing body 17 and / or the housing core 18 and which extend over the inner circumference of the housing body 17 and the outer circumference of the housing core 18 protrude and connect these two components by means of a press fit axially and / or in a rotationally fixed manner. The associated end face 24 of the housing core 18, which has a mandrel shape that has an outer width that is essentially constant over its entire length, expediently abuts the inside of the end wall 19 in a stop-limited manner. In the area of these end faces, a swirl device 25 belonging to the nozzle 21 is provided, which rotates the media mixture upon entry into a section of the nozzle duct that is enlarged relative to the outlet opening 20 in such a way that transverse channels are formed between the end faces, which are approximately tangential in the nozzle 21 open.

Zwischen dem Außenumfang des Gehäusekernes 18 und dem Innenumfang des Gehäusekörpers 17 ist ein spaltförmiger Hüllraum mit einer im wesentlichen kontinuierlichen Spaltweite von weniger als zwei oder einem Millimeter, insbesondere von etwa einem halben Millimeter begrenzt, und dieser Hüllraum ist durch ein Überdruck-Ventil 26 unterteilt, dessen ringförmige Dichtlippe 27 näher beim vorderen als beim hinteren Ende des Hüllraumes liegt. Der Außenumfang und/oder der Innenumfang der Dichtlippe 27 ist zum vorderen Ende des Hüllraumes annähernd kegelstumpfförmig unter einem Kegelwinkel von etwa 90° erweitert und liegt mit einem im Querschnitt teilkreisförmig konvex abgerundeten, die Schließfläche dieses Ventilkörpers bildenden Ringrand an einer Gegenfläche an.Between the outer circumference of the housing core 18 and the inner circumference of the housing body 17 is a gap-shaped envelope with a substantially continuous gap width of less than two or one millimeter, in particular about half a millimeter, and this envelope is divided by a pressure relief valve 26, whose annular sealing lip 27 is closer to the front than to the rear end of the envelope. The outer circumference and / or the inner circumference of the sealing lip 27 is expanded in the shape of a truncated cone at a cone angle of approximately 90 ° to the front end of the envelope and lies with a ring edge which is convexly rounded in part cross-section and forms the closing surface of this valve body on a counter surface.

Die Dichtlippe 27 ist einteilig mit dem im Querschnitt über seine gesamte Länge massiven bzw. geschlossenen Gehäusekern 18 ausgebildet, über dessen ansonsten durchgehend zylindrischen Außenumfang sie vorsteht, wobei ihre Schließfläche mit geringem Abstand hinter der Zentrierung 23 am Innenumfang 29 des Gehäusemantels 28 des Gehäusekörpers 17 federnd anliegt. Auch dieser Innenumfang 29 hat im wesentlichen über die gesamte Länge des Gehäusemantels 28 bzw. des Hüllraumes konstante zylindrische Querschnitte, wobei die Dicke des Gehäusemantels 28 in der Größenordnung der Spaltweite des Hüllraumes oder darunter liegen kann.The sealing lip 27 is formed in one piece with the housing core 18, which is solid or closed in cross-section over its entire length, over the otherwise continuous cylindrical outer circumference of which it protrudes its closing surface rests resiliently at a small distance behind the centering 23 on the inner circumference 29 of the housing shell 28 of the housing body 17. This inner circumference 29 also has substantially cylindrical cross sections over the entire length of the housing shell 28 or the envelope, the thickness of the housing shell 28 being in the order of the gap width of the envelope or below.

Das Ventil 26 kann nur zur Förderung in Richtung zur Auslaßöffnung 20 öffnen und schließt rückfedernd bzw. bei entgegengesetzter Strömungsrichtung zwangsläufig selbstverstärkend. Die Dichtlippe 27 ist axial gegenüber dem Gehäusekörper 17 und dem Gehäusekern 18 bis auf ihre Verformungsbewegung festsitzend. Im Öffnungszustand gibt sie einen ringförmigen Durchtrittsspalt frei, der gegenüber der Spaltweite des Hüllraumes wesentlich enger ist und einen Zerstäubungsspalt bildet.The valve 26 can only open for delivery in the direction of the outlet opening 20 and closes resiliently or, in the opposite direction of flow, inevitably self-reinforcing. The sealing lip 27 is axially fixed relative to the housing body 17 and the housing core 18 except for their deformation movement. In the open state, it releases an annular passage gap, which is considerably narrower than the gap width of the envelope and forms an atomizing gap.

Zwischen der Schließfläche des Ventiles 26 und dem hinteren Ende des Gehäuses 3 bildet der zugehörige Längsabschnitt des Hüllraumes eine seinen Querschnitten entsprechende Medienkammer 30, die am vorderen Ende durch die äußere, kegelstumpfförmige Flanke der Dichtlippe 27 begrenzt ist, welche somit bei geöffnetem Ventil eine zum Ventilspalt führende schräge Leitfläche bildet. Die Stirnseiten 31 des Gehäusekörpers 17 und des Gehäusekernes 18 liegen am anderen Ende im wesentlichen in einer gemeinsamen Ebene, wobei die Stirnfläche des Gehäusekernes 18 hier einteilig geschlossen ist, so daß in ihn weder Medium noch Luft aus der Druckkammer 6 eintreten kann. Beide Stirnseiten 24, 31 sind durchgehend eben.Between the closing surface of the valve 26 and the rear end of the housing 3, the associated longitudinal section of the envelope forms a media chamber 30 corresponding to its cross sections, which is delimited at the front end by the outer, truncated-cone-shaped flank of the sealing lip 27, which thus, when the valve is open, is one to the valve gap leading oblique guide surface. The end faces 31 of the housing body 17 and the housing core 18 lie at the other end essentially in a common plane, the end face of the housing core 18 being closed in one piece here, so that neither medium nor air from the pressure chamber 6 can enter it. Both end faces 24, 31 are flat throughout.

Das zugehörige Ende der Medienkammer 30 bildet etwa in der Ebene der Stirnseiten 31 eine Ringöffnung, die etwa gleich weit wie die übrige Medienkammer 30 ist und mit zwei im Abstand einander gegenüberliegenden Zonen Einlaßöffnungen bzw. einen Einlaß 32 bildet, über welchen die Druckkammer 6 ventil- und verschlußfrei an die Medienkammer 30 angeschlossen ist. Der Auslaßkanal 12 reicht zu diesem Zweck bis an die Stirnseiten 31.The associated end of the media chamber 30 forms an annular opening approximately in the plane of the end faces 31, which is approximately the same width as the rest of the media chamber 30 and forms inlet openings or an inlet 32 with two zones located opposite one another, via which the pressure chamber 6 valve- and is connected to the media chamber 30 without a lock. For this purpose, the outlet duct 12 extends to the end faces 31.

Zum Verschluß der Ringöffnung zwischen den Einlässen 32 bilden die Folienabschnitte 13, 14 im Anschluß an den Hals 11 quer nach außen abgewinkelte Folienteile 33, die an beiden Stirnseiten 31 haftend, z.B. durch Schweißung, befestigt sind und in diesem Bereich die Ringöffnung abgedichtet überdecken. Die Folienteile 33 liegen quer zur Teilungsebene 37 zwischen den Folienabschnitten 13, 14, in welchen auch deren Ränder 9 liegen und miteinander verbunden sind, wodurch die Folienteile 33 quer zur längeren Querschnittserstreckung des Auslaßkanales 12 vorgesehen sind.To close the ring opening between the inlets 32, the film sections 13, 14, following the neck 11, form transversely angled film parts 33 which adhere to both ends 31, e.g. by welding, and cover the ring opening in a sealed manner in this area. The film parts 33 lie transversely to the parting plane 37 between the film sections 13, 14, in which their edges 9 also lie and are connected to one another, as a result of which the film parts 33 are provided transversely to the longer cross-sectional extent of the outlet channel 12.

Die Befestigung der Folienteile 33 kann so vorgesehen sein, daß sie auch unter den auftretenden Betriebsdrücken, nämlich beim Betätigen der Gaspumpe 5, hält oder sie kann so vorgesehen sein, daß sich die Folienteile 33 unter diesem Druck von selbst von den Stirnseiten 31 ablösen und dadurch auch die zuvor verschlossenen Zonen der Ringöffnung zur Bildung eines entsprechend größeren Einlasses geöffnet werden; in diesem Fall könnten die Folienteile 33 die Ringöffnung im Ausgangszustand auch vollständig verschließen, so daß eine Art Aufreiß-Einlaßventil gebildet ist, das druckabhängig öffnet. Ist mindestens ein Einlaß 32 auch im Ausgangszustand zur Druckkammer 6 bzw. zum Auslaßkanal 12 offen, so kann ein Übertreten des in die Medienkammer 30 gefüllten Mediums in den Auslaßkanal 12 bzw. die Druckkammer 6 dadurch verhindert werden, daß das Medium verhältnismäßig dicht gepackt in der Medienkammer 30 angeordnet ist bzw. ihre kapillarartig geringe Spaltweite und der an den Einlässen 32 anstehende Überdruck der Druckkammer 6 zur dauerhaften Lagesicherung dieses Mediums beitragen.The fastening of the film parts 33 can be provided in such a way that it also holds under the operating pressures that occur, namely when the gas pump 5 is actuated, or it can be provided that the film parts 33 automatically detach themselves from the end faces 31 under this pressure and thereby the previously closed zones of the ring opening are also opened to form a correspondingly larger inlet; in this case, the film parts 33 could also completely close the ring opening in the initial state, so that a type of tear-open inlet valve is formed which opens depending on the pressure. If at least one inlet 32 is also open in the initial state to the pressure chamber 6 or to the outlet channel 12, one can Passing of the medium filled into the media chamber 30 into the outlet channel 12 or the pressure chamber 6 can be prevented by the medium being arranged in a relatively densely packed manner in the media chamber 30 or its capillary-like small gap width and the excess pressure of the pressure chamber 6 present at the inlets 32 contribute to the permanent securing of the position of this medium.

Die Folienteile 33 sind um die zugehörige Endkante des Gehäuses 3 bzw. des Gehäusekörpers 17 an dessen Außenumfang geschlagen, den sie über den Umfang und/oder seine Länge im wesentlichen ununterbrochen anliegend, mit Folienteilen 34 umhüllen, so daß das Gehäuse 3 axial zuggesichert fest mit dem Griff 4 bzw. der Gaspumpe 5 verbunden ist. Durch die Art der Verbindung der Folienabschnitte 13, 14 sowie durch die Querschnittsform des Halses 11 und die Versteifungswirkung der nach Art einer Randrippe verbundenen Ränder 9 ist zwischen dem Gehäuse 3 und dem Griff 4 bzw. der Gaspumpe 5 ein Gelenk 35 geschaffen, das es nach Art eines durch Fluiddruck versteiften, federnden Biegegelenkes aus biegeschlaffen Bauteilen erlaubt, diese beiden Bereiche gegeneinander aus der Mittellage gemäß Fig. 3 nach beiden Seiten um mindestens 90° oder mehr, also insgesamt um mindestens 180°, zu verschwenken. Zwar ist auch eine geringe Verschwenkbarkeit parallel zur Teilungsebene 37 gegeben, jedoch ist die Schwenkbewegung hauptsächlich um eine Gelenkachse 36 möglich, die etwa parallel zur bzw. in der Teilungsebene 37 sowie quer bzw. rechtwinklig zur Mittelachse 10 und diese schneidend liegt.The film parts 33 are wrapped around the associated end edge of the housing 3 or of the housing body 17 on its outer circumference, which they lie essentially continuously over the circumference and / or its length, with film parts 34, so that the housing 3 is secured axially with tension the handle 4 or the gas pump 5 is connected. Due to the type of connection of the film sections 13, 14 and the cross-sectional shape of the neck 11 and the stiffening effect of the edges 9 connected in the manner of an edge rib, a joint 35 is created between the housing 3 and the handle 4 or the gas pump 5, which it follows Type of a resilient bending joint stiffened by fluid pressure from limp components allows these two regions to be pivoted against each other from the central position according to FIG. 3 by at least 90 ° or more, that is to say a total of at least 180 °. Although there is also a slight pivotability parallel to the parting plane 37, the pivoting movement is possible mainly about an articulation axis 36 which is approximately parallel to or in the parting plane 37 and transversely or at right angles to the central axis 10 and intersecting it.

Im Ausgangszustand ist die jeweilige Auslaßöffnung 20 bzw. Düsenkuhle 22 an der Außenseite der Austragvorrichtung 2 bzw. des Gehäuses 3 druckdicht mit einem formstabilen Verschluß 39 verschlossen, der Bestandteil eines gemeinsamen, stabförmigen Trägers 40 für die Mehrzahl von Austragvorrichtungen 2 ist, die einzige Verbindung der jeweiligen Austragvorrichtung 2 zu diesem Träger 40 herstellt und einteilig mit dem Träger 40 ausgebildet ist. Zur Bildung des jeweiligen Verschlusses weist der biegeelastische Träger 40 einen über eine Profilseite flach vorstehenden Vorsprung auf, der mit seiner Stirnfläche ganzflächig an der die Auslaßöffnung 20 bzw. die Düsenkuhle 22 umgebenden Ringfläche des Gehäuses 3 haftend, z.B. durch Schweißung, befestigt ist, wobei diese Befestigung eine Sollbruch-Verbindung 41 bildet, die ohne Zerstörung des Gehäuses 3 oder von dessen zugehöriger Stirnfläche gelöst werden kann.In the initial state, the respective outlet opening 20 or nozzle cavity 22 on the outside of the discharge device 2 or the housing 3 is pressure-tight with a dimensionally stable Closure 39 closed, which is a component of a common, rod-shaped carrier 40 for the plurality of discharge devices 2, the only connection of the respective discharge device 2 to this carrier 40 and is formed in one piece with the carrier 40. To form the respective closure, the resilient support 40 has a protrusion which projects flatly over a profile side and which is attached with its end face to the ring surface of the housing 3 surrounding the outlet opening 20 or the nozzle cowl 22, for example by welding, and this is fastened Attachment forms a predetermined breaking connection 41, which can be released without destroying the housing 3 or from its associated end face.

Im Bereich des Verschlußvorsprunges ist der Träger 40 an seiner von der Verbindung 41 abgekehrten Seite mit einer napfförmigen Vertiefung versehen, so daß die zum Verschluß dienende Stirnwand des Verschlusses 39 verhältnismäßig dünnwandig flexibel ist und dadurch zum erleichterten Lösen vom Gehäuse 3 in sich geringfügig nach Art eines Hohlprofiles verformt werden kann. Die Verbindung der Austragvorrichtungen 2 mit dem Träger 40 ist so vorgesehen, daß die Austragvorrichtungen 2 frei hängend mit dem Träger 40 gelagert werden können.In the area of the locking projection, the carrier 40 is provided on its side facing away from the connection 41 with a cup-shaped recess, so that the end wall of the closure 39 used for the closure is relatively thin-walled flexible and thus slightly easier to release from the housing 3 in the manner of a Hollow profile can be deformed. The connection of the discharge devices 2 with the carrier 40 is provided so that the discharge devices 2 can be freely suspended with the carrier 40.

Zum Gebrauch der Austragvorrichtung wird diese zunächst von dem Verschluß 39 bzw. dem Träger 40 abgerissen, wodurch die Austragöffnung 20 geöffnet wird. Dann wird das Gehäuse 3, manuell gehalten an dem Griff 4, mit der Austragöffnung 20 an die gewünschte Anwendungsstelle herangeführt bzw. z.B. in eine Öffnung eingeführt, wonach die Handhaben 15, 16 zusammengedrückt werden. Dadurch strömt das Treibmittel aus dem Druckraum 6 über die Einlässe 32 in die gefüllte Medienkammer 30, bis der Öffnungsdruck des Ventiles 26 erreicht ist. Danach reißt das Treibmittel das Medium vorzerstäubt in eine Zwischenkammer 38, die zwischen der Dralleinrichtung 25 bzw. der Düse 21 und dem Ventil 26 im Bereich der Zentrierung 23 durch das vordere Ende des Hüllraumes gebildet ist, durch ihre Strukturierung wegen der Zentrierrippen oder dgl. als Misch- bzw. Wirbelkammer dienen kann, im Ausgangszustand leer bzw. nur gasgefüllt ist, bis an die Querkanäle reicht und zwischen diesen und der Medienkammer 30 einen Abschnitt eines Austragkanales bildet.To use the discharge device, it is first torn off from the closure 39 or the carrier 40, as a result of which the discharge opening 20 is opened. Then the housing 3, held manually on the handle 4, is brought with the discharge opening 20 to the desired application site or, for example, inserted into an opening, after which the handles 15, 16 are pressed together. As a result, the propellant flows out of the pressure chamber 6 the inlets 32 into the filled media chamber 30 until the opening pressure of the valve 26 is reached. The propellant then tears the medium into a intermediate chamber 38, which is formed between the swirl device 25 or the nozzle 21 and the valve 26 in the region of the centering 23 through the front end of the envelope, by its structuring because of the centering ribs or the like Mixing or swirl chamber can serve, in the initial state is empty or only gas-filled, extends to the transverse channels and forms a section of a discharge channel between them and the media chamber 30.

Von dieser Zwischenkammer 38 gelangt die Mischung aus Wirkmedium und Treibmittel über die Dralleinrichtung 25 in die Düse 21 und von dort durch die Auslaßöffnung 20 ins Freie. Nach diesem einmaligen Gebrauch, bei dem das Medium im wesentlichen restefrei aus der Medienkammer 30 ausgetragen wird, kann die gesamte Austragvorrichtung 2 weggeworfen bzw. der Wiederverwertung ihrer Materialanteile zugeführt werden. Alle ihre einzelnen Bauteile sind aus solchen Werkstoffen bzw. Kunststoffen hergestellt, die gemeinsam zur Wiederverwertung zum Zwecke der Herstellung eines Kunststoff-Ausgangsproduktes geeignet sind.The mixture of active medium and propellant passes from this intermediate chamber 38 via the swirl device 25 into the nozzle 21 and from there through the outlet opening 20 into the open. After this one-time use, in which the medium is discharged from the media chamber 30 essentially free of residues, the entire discharge device 2 can be thrown away or recycled for its material components. All of their individual components are made of such materials or plastics that are jointly suitable for recycling for the purpose of producing a plastic starting product.

Die Durchlaßquerschnitte des Auslaßkanales 12 können etwa in der Größenordnung der Durchlaßquerschnitte der Medienkammer 30 liegen oder demgegenüber größer sein. Die Durchlaßquerschnitte der Zwischenkammer 38 sind gegenüber denen der Medienkammer 30 etwa gleich groß bzw. eher kleiner, wobei die Durchlaßquerschnitte des Ventiles 26 im geöffneten Zustand demgegenüber wesentlich kleiner sind. Auch die Durchlaßquerschnitte der Querkanäle bzw. der Dralleinrichtung 25, der Düse 21 und der Auslaßöffnung 20 sind gegenüber den zuvor genannten Durchlaßquerschnitten wesentlich kleiner. Die Austragvorrichtung ist auch dafür geeignet, die Druckkammer 6 und die Medienkammer 30 mit demselben Medium zu füllen bzw. die Medienkammer im Ausgangszustand ungefüllt zu lassen und auszutragendes Medium nur in der Druckkammer zu speichern, das dann erst bei der Austragbetätigung in die Kammer 30 gelangt.The passage cross sections of the outlet channel 12 can be approximately in the order of the passage cross sections of the media chamber 30 or, on the other hand, be larger. The passage cross-sections of the intermediate chamber 38 are approximately the same size or rather smaller than those of the media chamber 30, the passage cross-sections of the valve 26 in the open state, on the other hand, being significantly smaller. The passage cross sections of the Cross channels or the swirl device 25, the nozzle 21 and the outlet opening 20 are significantly smaller compared to the aforementioned passage cross sections. The discharge device is also suitable for filling the pressure chamber 6 and the media chamber 30 with the same medium or for leaving the media chamber unfilled in the initial state and storing the medium to be discharged only in the pressure chamber, which then only enters the chamber 30 when the discharge is actuated.
