Abstract

The dispenser comprises a main body (4,5) and a medium accumulator (8), and discharges by movement between end positions. The metered contents of the accumulator are discharged through an outlet (30) almost or entirely in a single stroke, and/or it incorporates an oblong hollow body, typically a hollow steel needle. The accumulator outlet (18) can be upstream of the first outlet (30), while its inlet (17) is further upstream. The accumulator preferably protrudes into a closed chamber (12). Mixing equipment for a second medium with the first can be provided, thus functioning as a propellant and being delivered by pump into the accumulator.

Description

Die Erfindung betrifft einen Spender nach dem Oberbegriff des Patentanspruches 1. Die zum Austrag bzw. zur Verteilung vorgesehenen Medien können gasförmig, flüssig, pastös und/oder pulverförmig sein. Das Medium kann bereits innerhalb der Vorrichtung stromaufwärts des Medienauslasses oder bei dessen Verlassen feinst zerstäubt werden. So bilden selbst kleinste Medienmengen eine sehr große wirksame Oberfläche. Das Medium kann ein pharmazeutischer, kosmetischer oder technischer Wirkstoff sein. Dieser wird durch eine manuelle, wenigstens einen Teil des Spenders verkürzende Betätigung so ausgetragen, dass er sich an der Begrenzung des Medienauslasses von der Austragvorrichtung vollständig ablöst.The invention relates to a dispenser according to the preamble of the claim 1. The media intended for discharge or distribution can be gaseous, be liquid, pasty and / or powdery. The medium can already be within the Device upstream of the media outlet or when it exits be atomized. So even the smallest amounts of media form a very large effective one Surface. The medium can be pharmaceutical, cosmetic or be a technical active ingredient. This is done by a manual, at least one Part of the donor's shortening actuation is carried out so that it is at the limit of the media outlet completely detaches from the discharge device.

Für das Medium ist ein Speicher vorgesehen, welcher als Dosierkammer bereits bei der Herstellung der Vorrichtung gefüllt wird. Er kann auch nach jedem Medienaustrag ähnlich einer Pumpenkammer aus einem Hauptspeicher wieder nachgefüllt werden. Statt nur eines einzigen Speichers können auch mehrere Speicher achsgleich hintereinander und/oder in einer kranzförmigen Reihe nebeneinander vorgesehen und in aufeinanderfolgenden Betätigungsschritten mit Zwischenpausen nacheinander durch den Medienauslass zu entleeren sein. A storage is provided for the medium, which already acts as a dosing chamber is filled in the manufacture of the device. He can also after every media release Refilled from a main storage similar to a pump chamber become. Instead of a single memory, multiple memories can be used axially one behind the other and / or in a ring-shaped row next to each other provided and in successive operating steps with pauses have to be emptied one after the other through the media outlet.

Die GB-A-1 488 719 zeigt einen Spender, bei welchem der Speicher durch eine außen auf einen Hohldorn aufzusetzende Pulverkartusche gebildet ist, die zwar langgestreckt ist, deren Speicherraum jedoch in Strömungsrichtung spitzwinklig konisch verjüngt und am Austragende nochmals erweitert ist, so dass sich ein Speicher mit verhältnismäßig großem Durchmesser und kegelstumpfförmigem Ende ergibt.GB-A-1 488 719 shows a dispenser in which the memory is provided by a Powder cartridge to be placed on the outside of a hollow mandrel, although is elongated, but its storage space is acute-angled in the direction of flow is tapered and expanded again at the discharge end, so that a Storage with a relatively large diameter and frustoconical End results.

Der Erfindung liegt die Aufgabe zugrunde, einen Spender für Medien zu schaffen, bei welchem Nachteile bekannter Ausbildungen vermieden sind und mit welchem insbesondere auch kleinste Medienmengen sicher gespeichert und im wesentlichen restlos ausgetragen werden können.The object of the invention is to create a dispenser for media, which disadvantages of known training are avoided and with which in particular even the smallest amounts of media are securely stored and essentially can be carried out completely.

Erfindungsgemäß sind die Merkmale nach Patentanspruch 1 vorgesehen. Der Speicher bzw. dessen das Medium aufnehmender Raum weist eine sehr langgestreckte Form auf, deren Weite bzw. Durchmesser kleiner als 5, 3 bzw. 1 mm betragen kann, so dass das darin enthaltene Medium die Form eines langen dünnen Stiftes annimmt. Die Innenweite des Kanülen-Speichers kann dem Vier- oder Sechsfachen seiner Wandungsdicke entsprechen und die Länge des Kanülen- oder Speicherraumes kann dem Vier- oder Sechsfachen seiner Innenweite entsprechen, wobei diese Werte jeweils Höchst- oder Mindestwerte darstellen können. Zweckmäßig ist die Wandungsdicke über den Umfang und die Länge des Speicherkörpers konstant. Der Speicherkörper kann in einfacher Weise durch einen Abschnitt einer zylindrischen Hohlnadel aus Kunstsstoff, Stahl, wie rostfreiem Stahl, durchsichtigem Werkstoff, wie Glas, oder dergleichen gebildet sein, so dass sich eine sehr einfache Herstellung ergibt. Der Speicherkörper enthält unabhängig vom Medium nicht-polymeres oder nicht-gläsernes Material, wie Metall oder dergleichen.According to the features of claim 1 are provided. The Storage or its space accommodating the medium is very elongated Form, whose width or diameter is less than 5, 3 or 1 mm may be such that the medium contained therein is in the form of a long thin one Pen accepts. The inside width of the cannula can be four or four Correspond to six times its wall thickness and the length of the cannula or Storage space can be four or six times its internal width, where these values can represent maximum or minimum values. expedient is the wall thickness over the circumference and the length of the storage body constant. The storage body can be easily through a section a cylindrical hollow needle made of plastic, steel, such as stainless steel, transparent Material, such as glass, or the like can be formed, so that a very simple manufacture results. The storage body contains regardless of the medium non-polymeric or non-glass material such as metal or the like.

Unabhängig von der beschriebenen Ausbildung kann an einer zur Austragbetätigung gegenüber dem Medienauslass bewegbaren Einheit der Vorrichtung ein Körper vorgesehen sein, welcher im Laufe der Betätigungsbewegung einen Verschluss einer Kammer öffnet, z.B. durch Stich. Der Raum dieser Kammer kann unmittelbar an das gespeicherte Medium angrenzen, den Öffnungskörperper oder den Speicher wenigstens teilweise aufnehmen und als Druckraum ausgebildet sein, welcher vor dem Öffnen unter Überdruck steht. Der Öffnungskörper kann unmittelbar durch den Speicher gebildet sein.Regardless of the training described, one can be used for discharge control a body of the device that is movable relative to the media outlet be provided which a closure in the course of the actuating movement a chamber opens, e.g. by stitch. The space of this chamber can be immediate adjoin the stored medium, the opening body or at least partially record the memory and as Pressure chamber to be formed, which before opening There is overpressure. The opening body can go straight through the memory be formed.

Vorteilhaft ist vorgesehen, daß auf einem ersten, an die Ausgangsstellung anschließenden Teilweg der Betätigung in der Vorrichtung ein Überdruck aufgebaut wird, welcher permanent auch auf das gespeicherte Medium von voneinander abgekehrten Seiten her wirken kann, so daß das fließfähige Medium gegenüber dem Speicher zunächst noch keine Strömungsbewegungen ausführt. In einem anschließenden Teil der gleichgerichtet weitergehenden Betätigungsbewegung wird das Medium an einer der genannten Seiten von dem Druck entlastet und an dieser Seite mit dem Medienauslaß ohne weiteres zwischengeschaltetes Ventil leitungsverbunden, so daß durch den nach wie vor an der anderen Seite wirksamen Druck das Medium aus dem Speicher und durch den Medienauslaß schlagartig ausströmt.It is advantageously provided that on a first, to the Starting position subsequent partial route of actuation in the Device an overpressure is built up, which is permanent also on the stored medium from each other Sides can act here, so that the flowable medium opposite the flow initially no flow movements performs. In a subsequent part of the rectified further actuation movement, the medium is at a relieves the pressure from the sides mentioned and at this Side with the media outlet easily interposed Valve connected to the line, so that the still on on the other hand, effective media pressure from the memory and suddenly flows out through the media outlet.

Besonders vorteilhaft ist es, wenn der Speicher im wesentlichen vollständig und zum größten Teil berührungsfrei innerhalb einer Druck- bzw. Pumpkammer einer Fluidpumpe, wie einer Gas- oder Luftpumpe, so angeordnet ist, daß in wenigstens einer Betätigungsstellung oder in allen Betätigungsstellungen ein oder mehrere Speichereinlässe für das Fluid und/oder ein im Abstand davon liegender Speicherauslaß für das Medium an die Druckkammer angeschlossen bzw. dem darin herrschenden Druck ausgesetzt sind. Der Speicher oder ein anderer Stechdorn kann dann den bewegbaren Kammerverschluß, beispielsweise einen Schubkolben, im Laufe der Betätigungsbewegung von innen so durchdringen, daß sein Speicherauslaß abgedichtet außerhalb der Druckkammer liegt und das in den Speichereinlaß nun einströmende Fluid das Medium geradlinig durch den Speicherauslaß herausdrückt. It is particularly advantageous if the memory essentially completely and for the most part without contact within a pressure or pumping chamber of a fluid pump, such as a gas or air pump is arranged so that at least one operating position or in all operating positions one or more storage inlets for the fluid and / or a memory outlet for the medium is connected to or in the pressure chamber prevailing pressure. The memory or a other spike can then the movable chamber closure, for example a thrust piston, in the course of the actuation movement penetrate from the inside so that its memory outlet sealed outside the pressure chamber and that in the Fluid inlet now inflowing the medium straight through the memory outlet.

Sowohl das Medium als auch das Fluid können steril verpackt und druckdicht verschlossen innerhalb einer Speichereinheit vorgesehen sein, die in den den Medienauslaß aufweisenden Grundkörper zunächst ohne Öffnung der Speicherräume in die Ausgangsstellung einzusetzen und nachfolgend durch Betätigung zu entleeren ist. Dieser Grundkörper bedarf hierzu keines unmittelbar den Verschluß öffnenden Gliedes, wie eines Stechdornes, einer Nadel oder dergleichen, da dieses Öffnungsglied bereits Bestandteil der Speichereinheit ist.Both the medium and the fluid can be packaged sterile and sealed pressure-tight within a storage unit be provided that in the media outlet Basic body first without opening the storage spaces in the Starting position and then by pressing is to be emptied. This basic body does not require any immediate opening member, like one Prick, a needle or the like, since this opening member is already part of the storage unit.

Jeder der beiden Speicher, insbesondere der Fluidspeicher, kann auch eine mit dem Grundkörper vorgefertigte Einheit bilden und über eine Hemmung festsitzend so mit dem Grundkörper verbunden sein, daß er erst nach Aufbringen einer Betätigungskraft gegenüber dem Grundkörper bewegbar ist, die wesentlich größer als die unmittelbar anschließend über den Restweg aufzubringende Betätigungskraft ist. Dadurch ergibt sich eine schlagartig einsetzende und sehr schnelle Betätigungsbewegung, welche hohe Strömungsgeschwindigkeiten des Mediums bzw. Fluids bewirkt und dessen Zerstäubung verbessert. Die Hemmung, die auch eine gegen Rückzug sichernde Schnappverbindung sein könnte, ist zweckmäßig durch eine Sollbruchstelle gebildet, so daß eine einteilige Ausbildung des Speicherkörpers mit dem Grundkörper möglich ist.Each of the two stores, in particular the fluid store, can also be a unit prefabricated with the base body form and stuck with an inhibition so with the body be connected that he only after applying an operating force is movable relative to the base body much larger than that immediately afterwards via the Actuating force to be applied is the remaining distance. This gives a sudden and very fast actuation movement what high flow velocities of the Medium or fluid causes and improves its atomization. The inhibition, which is also a safeguard against withdrawal Snap connection could be useful through a Breakage point formed, so that a one-piece training of the storage body with the base body is possible.

Der Medien-Speicher kann auch an einem von dem Speicherkörper für das Fluid bzw. von einem anderen Tragkörper gesonderten Haltekörper vorgesehen sein und mit diesem eine vormontierte Einheit bilden, die auswechselbar an dem Tragkörper zu befestigen ist, wenn sich dieser in Ausgangslage befindet.The media storage can also be attached to one of the storage bodies for the fluid or separate from another support body Holding body be provided and with this a pre-assembled Form unit that can be replaced on the support body fasten when it is in the starting position.

Diese und weitere Merkmale gehen außer aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor. These and other features go beyond the claims also from the description and the drawings.

Die Austragvorrichtung bzw. der Spender 1 weist zwei gegeneinander axial linear verschiebbare Einheiten 2, 3 als Austragbetätigung auf, welche im wesentlichen die gesamte Vorrichtung bilden und von denen die Einheit 2 in allen Betätigungsstellungen permanent vollständig innerhalb der Einheit 3 liegen kann. Als äußersten, formsteifen Teil weist die Einheit 2 einen Grundkörper 4 und die Einheit 3 einen Grundkörper 5 auf, welche jeweils mit einer freiliegenden Handhabe 6, 7 zur manuellen Betätigung versehen sind. Vollständig innerhalb der Grundkörper 4,5 und nahe benachbart zur Handhabe 6 ist ein Speicher 8, nämlich ein nadeldünnes Rohr vorgesehen, welches mit dem größten Teil seiner Länge berührungsfrei innerhalb eines Speichers 9 für ein gasförmiges Fluid liegt. Sämtliche Bauteile sind in einer Achse 10 vorgesehen und bis auf die Körper 5, 8 rotationssymmetrisch. The discharge device or the dispenser 1 has two against each other axially linearly displaceable units 2, 3 as Discharge operation, which essentially covers the entire Form device and of which the unit 2 in all Operating positions permanently completely within the Unit 3 can be. As the outermost, dimensionally stable part the unit 2 a base body 4 and the unit 3 one Base body 5, each with an exposed Handle 6, 7 are provided for manual actuation. Completely within the base body 4.5 and close to adjacent Handle 6 is a memory 8, namely a needle-thin tube provided which is contact-free with most of its length within a storage 9 for a gaseous Fluid lies. All components are in an axis 10 provided and except for the body 5, 8 rotationally symmetrical.

Die Rohrinnenfläche des Speichers 8 begrenzt eine zylindrische Speicherkammer 11 für ein Medium, das wie Pulver so dicht gepackt in den Speicher 8 verfüllt werden kann, daß seine Fließfähigkeit gegenüber seinem gelockerten Zustand wesentlich verringert, nämlich so zäh ist, daß es ohne äußere Einwirkung nicht von selbst fließen kann. Eine im Volumen mindestens hundert- oder zweihundertfach größere Kammer 12 für das Fluid bildet der Speicher 9. Die Kammer 12 ist im Bereich des Speichers 8, an dessen Umfang sie angrenzt, im Querschnitt koaxial ringförmig. Der Grundkörper 4 oder ein anderer Körper ist als Tragkörper 13 für den Speicher 8 vorgesehen und an dem den Speicher 8 tragenden Boden dicht verschlossen. Der Körper 4, 13 weist einen rohrförmigen Mantel 14 mit über seine Länge durchgehend konstantem Innenund/oder Außenquerschnitt auf, der so aus durchsichtigem Werkstoff bestehen kann, daß der Speicher 8 radial von außen sichtbar ist. Am unteren Ende des Mantels 14 ist ein Verschluß- und Haltekörper 15 befestigt, welcher mit einem gegenüber seinem Durchmesser höchstens so langen Abschnitt festsitzend sowie dicht in den Innenumfang des Mantels 14 eingesetzt ist und über eine Ringschulter an der unteren Endfläche des Mantels 14 mit einem äußeren Endabschnitt anliegt, dessen Außenumfang eine gleich weite Fortsetzung des Außenumfanges des Mantels 14 bildet. Der Deckel 15 könnte auch einteilig mit dem Mantel 14 ausgebildet oder durch eine Schnappverbindung oder dergleichen auswechselbar angeordnet sein.The inner tube surface of the memory 8 defines a cylindrical one Storage chamber 11 for a medium like powder so packed tightly in the memory 8 that its fluidity compared to its relaxed state significantly reduced, namely so tough that it has no external Action cannot flow by itself. One in volume at least a hundred or two hundred times larger chamber 12 for the fluid forms the memory 9. The chamber 12 is in the Area of the memory 8, the periphery of which it borders, in Cross-section coaxially ring-shaped. The base body 4 or one another body is as a support body 13 for the memory 8 provided and sealed to the bottom bearing the memory 8 locked. The body 4, 13 has a tubular Jacket 14 with a constant inside and / or over its length External cross-section, which is made of transparent Material can consist that the memory 8 radially from the outside is visible. At the lower end of the jacket 14 is a closure and holding body 15 attached, which with a compared to its diameter at most as long a section tight and tight in the inner circumference of the jacket 14 is inserted and over a ring shoulder on the lower End surface of the jacket 14 with an outer end portion is present, the outer circumference of an equally wide continuation of the The outer circumference of the jacket 14 forms. The lid 15 could also formed in one piece with the jacket 14 or by a Snap connection or the like interchangeably arranged his.

Den Körpern 8, 15 liegt mit Abstand ein Verschluß bzw. Kolben 16 gegenüber, der in Ausgangsstellung vollständig innerhalb der Kammer 21 bzw. des Mantels 14 liegt und einen Abstand vom oberen Ende des Körpers 4, 13 hat. Der Speicher 8 weist mit Abstand zwischen seinen Enden und näher beim unteren Ende als Speicher-Einlaß 17 mehrere über seinen Umfang verteilte Öffnungen auf, die seinen Mantel quer durchsetzen und jeweils eine kleinere Weite als die Kammer 11 haben. Die Öffnungen 17 können in ihrer Axialsicht kreisrund oder parallel zur Achse 10 bzw. in Umfangsrichtung des Speichers 8 langgestreckt sein. Das obere, durchgehend rechtwinklig quer zur Achse 10 liegende Ende des Speichers 8 begrenzt als Speicher-Auslaß 18 eine Öffnung, die gleich weit wie der Speicherraum ist. Dieses Ende des Speichermantels bildet eine ringförmige Stechspitze 19 von gleicher Weite wie der übrige Speicher 8. Unter Speicherweite ist die Innen- und/oder die Außenweite des Speichers 8 zu verstehen.The bodies 8, 15 are at a distance a closure or piston 16 opposite, in the starting position completely within the chamber 21 or the jacket 14 is located and a distance from has the upper end of the body 4, 13. The memory 8 has Distance between its ends and closer to the lower end than Memory inlet 17 several distributed over its circumference Openings that cross through his coat and each have a smaller width than the chamber 11. The openings 17 can be circular in their axial view or parallel to Axis 10 or elongated in the circumferential direction of the memory 8 his. The upper one, continuously perpendicular to the Axis 10 lying end of the memory 8 limited as a memory outlet 18 an opening that is as wide as the storage space is. This end of the storage jacket forms an annular one Lancing tip 19 of the same width as the rest of the memory 8. The inside and / or outside width is the storage width to understand the memory 8.

Mit Abstand von und zwischen seinen Endflächen weist der Kolben 16 im Zentrum als Verschluß eine kreisscheibenförmige Membran 20 oder dergleichen auf, die einteilig mit dem übrigen Kolben 16 aus einem Material ausgebildet ist, das weicher und elastischer als die Materialien der Bauteile 8, 14, 15 ist. Die Membran 20 bildet die Bodenflächen zweier entgegengesetzt spitzwinklig konisch erweiterter Vertiefungen, die in den Stirnflächen des Kolben 16 ihre größte Weite haben. Der Durchmesser dieser Bodenflächen bzw. der Membran 20 kann gleich der Außenweite des Speichers 8 bzw. der Spitze 19 oder demgegenüber geringfügig größer sein. Wird der Kolben 16 mit einem Betätigungsstößel oder dergleichen gegen den Speicher 8 bewegt, so erhöht sich der Druck in der Kammer 12, bis das Ende 19 die Membran 20 ohne Ablösung von Partikeln vollständig durchdrungen hat und in der Ebene der oberen Stirnfläche der Membran 20 vollständig innerhalb des Kolbens 16 liegt. Der Kolben 16 ist dann durch Anschlag an der Bodenfläche der Kammer 12 oder dergleichen festgelegt. Diese ebene Bodenfläche, die durch den Körper 15 gebildet sein kann, schließt so tangential an die unteren Begrenzungen der Öffnungen 17 und den Außenumfang des Speichers 8 an, daß in den Öffnungen 17 wie an der Öffnung 18 der Druck in der Kammer 12 ansteht. Der Speicher 8 ist mit seinem kürzeren, unteren und unmittelbar an die Öffnungen 17 sowie den Speicherraum anschließenden Endabschnitt in den Kammerboden abgedichtet in eine Sackloch-Vertiefung festsitzend und mit seiner Endfläche anschlagend eingesetzt, so daß er dem Druck durch den Kolben 16 und die Membran 20 nicht ausweicht. Die Weite des Speichers 8 ist kleiner als die Hälfte, ein Drittel oder ein Viertel der Weite der Kammer 12.At a distance from and between its end faces, the Piston 16 in the center as a closure disk-shaped Membrane 20 or the like, which are integral with the remaining piston 16 is formed from a material which softer and more elastic than the materials of the components 8, 14, 15 is. The membrane 20 forms the bottom surfaces of two oppositely conical recesses, the greatest width in the end faces of the piston 16 to have. The diameter of these floor surfaces or the membrane 20 can equal the outer width of the memory 8 or the tip 19 or slightly larger. Will the piston 16 with an actuating plunger or the like against the Memory 8 moves, the pressure in chamber 12 increases, until the end 19 the membrane 20 without detachment of particles has completely penetrated and in the level of the upper End face of the membrane 20 completely inside the piston 16 lies. The piston 16 is then by stop on the Floor area of the chamber 12 or the like set. This flat bottom surface formed by the body 15 can, tangentially connects to the lower boundaries of the Openings 17 and the outer periphery of the memory 8 at that in the openings 17 as at the opening 18 the pressure in the Chamber 12 is pending. The memory 8 is with its shorter, lower and directly to the openings 17 and the storage space subsequent end section in the chamber floor sealed in a blind hole and stuck with its end face used striking so that it can withstand the pressure through the piston 16 and the membrane 20 does not evade. The Width of the memory 8 is less than half, one third or a quarter of the width of chamber 12.

Der Speicher 8 und der Kolben 16 können vom unteren oder vom oberen Ende her in den Mantel 14 so eingesetzt werden, daß bereits nach der Montage und in der Ausgangsstellung ein Überdruck in der Kammer 12 herrscht. Bei der vom Boden 15 entfernten Öffnung 22 der Kammer 12 kann der Mantel 14 am Außenumfang seines zugehörigen Endabschnittes spitzwinklig konisch verjüngt sein. Der Kolben 16 ist am Innenumfang des die Kammer 12 begrenzenden Mantels 14 mit zwei ringförmigen Dichtlippen 23 unter radialer Vorspannung abgedichtet geführt, welche im Axialschnitt teilkreisförmig gekrümmt sind, im Axialabstand voneinander, von den Enden des Kolbens 16 sowie von der Membran 20 jeweils im Bereich einer der Vertiefungen liegen und in der Mitte der Axialstreckung ihres Überganges in den Kolbenumfang linienförmig den Innenumfang der Kammer 12 berühren. In Ausgangsstellung liegt die obere Endfläche 24 des Kolbens 16 gegenüber der Öffnung 22 bzw. der zugehörigen Endfläche des Mantels 14 um mindestens die Hälfte der Länge des Kolbens 16 zurückversetzt. Die Einheit 2 mit Speicher 8, Boden 15 und Kolben 16 kann mit den Speicherfüllungen vormontiert sein und dann an der Einheit 3 auswechselbar befestigt werden.The memory 8 and the piston 16 can from the lower or from upper end ago in the jacket 14 so that after installation and in the starting position There is overpressure in the chamber 12. At the floor 15 distant opening 22 of the chamber 12, the jacket 14 on The outer circumference of its associated end section is acute-angled be tapered. The piston 16 is on the inner circumference of the the chamber 12 delimiting jacket 14 with two annular Sealing lips 23 are guided in a sealed manner under radial prestress, which are partially circular in the axial section, at an axial distance from one another, from the ends of the piston 16 and of the membrane 20 in each case in the area of one of the depressions lie and in the middle of the axial extension of their Transition in the piston circumference linearly the inner circumference touch the chamber 12. The top position is in the starting position End face 24 of the piston 16 opposite the opening 22 or the associated end face of the jacket 14 by at least that Half the length of the piston 16 set back. Unit 2 with memory 8, bottom 15 and piston 16 can with the memory fillings be pre-assembled and then replaceable on unit 3 be attached.

Mit einem beliebigen, durch die Öffnung 22 einführbaren und hohlen Betätigungsstößel 25 kann die Einheit 2 auch ohne Einheit 3 betätigt und das Medium so aus dem vom Kolben 16 entfernten Ende des Stößels 25 ausgetragen werden. Der Stößel 25 könnte auch eine einteilige oder vormontierte Baueinheit mit dem Kolben 16 bilden und in Ausgangsstellung frei aus der Öffnung 22 vorstehen. Hier ist der Stößel 25 lagefest mit der Einheit 3 bzw. dem Grundkörper 5 verbunden und liegt mit seiner ebenen unteren Endfläche in Ausgangsstellung nur mit einem Spaltabstand von der Endfläche 24. Die Außenweite des Stößels 25 ist gleich der Außenweite des Kolben 16 benachbart zu den Dichtungen 23, so daß der permanent in den Mantel 14 eingreifende Stößel 15 und die Einheit 2 radial aneinander mit geringstem Radialspiel geführt sind.With any insertable through the opening 22 and hollow actuating plunger 25, the unit 2 can also without Unit 3 actuated and the medium from the piston 16 distal end of the plunger 25 are discharged. The pestle 25 could also be a one-piece or pre-assembled unit form with the piston 16 and in the starting position freely from the Project opening 22. Here the plunger 25 is in position with the Unit 3 or the base body 5 connected and lies with its flat lower end surface in the starting position only with a gap distance from the end face 24. The outer width of the Tappet 25 is adjacent to the outer width of the piston 16 to the seals 23 so that the permanent in the jacket 14th engaging plunger 15 and the unit 2 radially to one another are guided with the least radial play.

Der wie der Kolben 16 und der Verschluß 20 in der Achse 10 liegende Stößel 25 ist über seine ganze Länge von einem Auslaßkanal 26 durchsetzt, den er über seine gesamte Länge und seinen gesamten Umfang einteilig begrenzt. Ein unterer Endabschnitt 27 des Kanals 26 ist nach unten spitzwinklig auf eine Weite erweitert, die der größten Weite der zugehörigen Vertiefung in der Endfläche 24 entspricht und gleich seiner Länge sein kann. Der konische Abschnitt 27 dient zur Strömungsbeschleunigung des Fluid-Medien-Gemisches beim Austritt aus dem Auslaß 18 bzw. der Vertiefung in der Endfläche 24.Like the piston 16 and the closure 20 in the axis 10 lying plunger 25 is one over its entire length Exhaust passage 26 passes through it over its entire length and limits its entire scope in one piece. A lower one End section 27 of the channel 26 is at an acute angle downwards extended a width that the largest width of the associated Corresponds to depression in the end surface 24 and equal to it Length can be. The conical section 27 serves to accelerate the flow of the fluid-media mixture at the outlet from the outlet 18 or the depression in the end face 24.

Der längste, an den Kolben 16 anschließende Teil des Kanales 26 ist in einem vom Grundkörper 5 gesonderten Stößeldorn vorgesehen, dessen oberes, in der Außenweite abgesetztes Ende festsitzend in einen hülsenförmigen Stößelhalter 29 eigesetzt ist. Der Dorn 28 weist außerhalb des Halters 29 gleiche Außenweite wie dieser auf. Der Halter 29 ist kürzer als der Dorn 28 bzw. die Hälfte der Länge des Dornes, welcher mit seinem oberen Ende innerhalb des Halters 29 axial an einer ringförmigen Bodenfläche anschlägt. Diese ist von einer konstant weiten Fortsetzung des zylindrischen Teiles des Kanales 26 durchsetzt, welche unter Zwischenschaltung einer erweiterten Kammer oder Dralleinrichtung 31 in den Medienauslaß 30 mündet. In der Einrichtung 31 wird das Medium verwirbelt bzw. in Rotation um die Düsenachse 10 der Zerstäuberdüse 30 versetzt, so daß das Fluid-Medien-Gemisch unter dieser Drallströmung zerstäubt aus der Düse 30 von weniger als einem oder einem halben Millimeter Weite austritt. Das obere Ende des Dornes 28 könnte auch an die Einrichtung 31 bzw. deren Drallkammer angrenzen.The longest part of the channel adjoining the piston 16 26 is in a plunger mandrel separate from the base body 5 provided, the upper end, offset in the outer width firmly seated in a sleeve-shaped tappet holder 29 is. The mandrel 28 has the same outside the holder 29 Outside width like this on. The holder 29 is shorter than that Mandrel 28 or half the length of the mandrel, which with its upper end within the holder 29 axially at one ring-shaped bottom surface. This is from one constant wide continuation of the cylindrical part of the Passes through channel 26, which with the interposition of a expanded chamber or swirl device 31 in the media outlet 30 opens. The medium is swirled in the device 31 or in rotation around the nozzle axis 10 of the atomizing nozzle 30 offset so that the fluid-media mixture under this Swirl flow atomizes from the nozzle 30 of less than one or half a millimeter in width. The top end of the mandrel 28 could also on the device 31 or its Adjacent swirl chamber.

Die Austrittsdüse 30 ist am oberen Ende eines Stutzens 32 vorgesehen, dessen ballig oder sphärisch gekrümmte Endwand sie an der konvexen Außenseite durchsetzt und der zum Einführen in eine Körperöffnung, beispielsweise eine Nasenöffnung, geeignet ist. Der mit der Endwand und dem Halter 29 einteilig ausgebildete Mantel des Stutzens 32 umgibt den Stößel 25 auf gesamter Länge und den Körper 4, 13 auf einer Teillänge am Umfang mit Radialabstand, da der Halter 29 von der Innenseite der Endwand frei gegen den Körper 4, 13 vorsteht und in Ausgangsstellung nicht bis an die Öffnung 22 reicht, in welche er in Pumpendstellung hineinragt. Der Stutzen 32 ist mit dem Halter 29 ein vom Körper 5 gesonderter einteiliger Bauteil, der über eine Verbindung 33, wie eine Schnappverbindung, festsitzend an dem Körper 5 angeordnet ist. Der Stutzen 32 könnte auch einteilig mit dem Körper 5 ausgebildet sein.The outlet nozzle 30 is at the upper end of a nozzle 32 provided its spherical or spherically curved end wall it penetrates on the convex outside and that for insertion into a body opening, for example a nostril, suitable is. The one with the end wall and the holder 29 trained jacket of the socket 32 surrounds the plunger 25 entire length and the body 4, 13 on a partial length on Radial distance since the holder 29 from the inside the end wall projects freely against the body 4, 13 and in Starting position does not reach the opening 22 in which it protrudes into the pump end position. The neck 32 is with the holder 29 a separate one-piece from the body 5 Component that has a connection 33, such as a snap connection, is firmly attached to the body 5. The stub 32 could also be formed in one piece with the body 5.

Der Körper 5 ist im wesentlichen durch eine Kappe 34 mit einer in Axialansicht langgestreckten Stirnwand 35 gebildet, von der ein Kappenmantel 36 nur nach unten gerichtet absteht und deren Außenseite die ebenfalls langgestreckte Handhabe 7 bildet. Die Stirnwand 35 wird von Verbindungs- bzw. Schnappgliedern am unteren Ende des Mantels des Stutzens 32 durchsetzt, wobei diese Glieder formschlüssig an der Innenseite der Stirnwand 35 anliegen. Der Mantel 36 könnte auch entfallen, so daß der Teil 34 nur durch die Stirnwand 35 gebildet ist, über deren Unterseite die Einheit 2 und eine Hemmung 38 in jeder Stellung vorstehen. In der Unterkante des Mantels 36 ist mindestens ein diesen durchsetzender Ausschnitt 37 zum Eingriff des Daumens des Benutzers vorgesehen, da die von der Außenseite des Bodens 15 gebildete Handhabe 6 einschließlich des an den Stutzen 32 anschließenden Längsabschnittes der Einheit 2 in jeder Stellung vollständig innerhalb der Kappe 34 liegt. Der Ausschnitt 37 ist in einer oder beiden längeren Seiten des in Axialansicht wie die Handhabe 7 langrunden oder elliptischen Mantels 36 vorgesehen.The body 5 is essentially covered by a cap 34 an end wall 35 elongated in axial view, from which a cap jacket 36 only protrudes downward and the outside of which is also the elongated handle 7 forms. The end wall 35 is made of connecting or snap members penetrated at the lower end of the jacket of the socket 32, these links form-fitting on the inside the end wall 35 abut. The jacket 36 could also be omitted so that the part 34 is formed only by the end wall 35 is on the underside of the unit 2 and an escapement 38th project in any position. In the lower edge of the jacket 36 is at least one cutout 37 penetrating this Engagement of the user's thumb is provided since that of the Outside of the bottom 15 formed handle 6 including of the longitudinal section adjoining the connecting piece 32 Unit 2 completely inside the cap in every position 34 lies. The cutout 37 is longer in one or both Sides of the round 7 in axial view like the handle or elliptical jacket 36 is provided.

Die Einheit 2 bzw. deren genannte Bauteile sind in Ausgangsstellung mit der Einheit 3 über die Hemmung 38 miteinander verbunden, welche in der Ebene der Stirnwand 35 oder mit Abstand darunter liegen kann. Diese Hemmung könnte federnd ausrastend, mit erhöhter Reibung, über eine Sollbruchstelle oder dergleichen in den Außenumfang des Körpers 4, 13 mit Abstand zwischen dessen Enden eingreifen. Mit Überwinden der Hemmung 38 durch die Austragbetätigung wird die Hemmkraft schlagartig aufgehoben und die Einheiten 2, 3 können wesentlich leichtgängiger gegeneinander bis zum Anschlag des Kolbens 16 oder dergleichen verschoben werden. Über die Außenseite der Stirnwand 35 und über die Handhabe 7 steht mit Radialabstand innerhalb des Außenumfanges der Handhabe 7 eine hülsenförmige Schürze 39 in den Stutzen 32 vor, welche einteilig mit dem Körper 5 ausgebildet sein kann und den Körper 4, 13 am Außenumfang mit Radialabstand sowie mit Abstand von dessen Enden umgibt. An dieser Schürze 39 kann der Stutzen 32 radial zentriert bzw. geführt sein, wodurch seine Schnappglieder in der Riegelstellung gesichert sind.The unit 2 and its components are in the starting position with the unit 3 via the escapement 38 with each other connected, which in the plane of the end wall 35 or with Distance may be below. This inhibition could be springy disengaging, with increased friction, over a predetermined breaking point or the like in the outer circumference of the body 4, 13 with Intervene between the ends. With overcoming the Inhibition 38 by the discharge actuation becomes the inhibitory force abruptly canceled and the units 2, 3 can be essential smoother against each other until the stop of the Piston 16 or the like can be moved. About the Outside of the end wall 35 and about the handle 7 is with Radial distance within the outer circumference of the handle 7 a sleeve-shaped apron 39 in the neck 32, which can be formed in one piece with the body 5 and the Body 4, 13 on the outer circumference with radial distance and with Distance from its ends surrounds. On this apron 39 can the nozzle 32 may be radially centered or guided, whereby its snap links are secured in the latch position.

Bei Nichtgebrauch kann der Stutzen 32 vollständig mit einer Steck-Kappe 41 abgedeckt sein, welche den Stutzen 32 eng umgibt, bis zur Handhabe 7 reicht und die Düse 30 abdeckt. When not in use, the nozzle 32 can be completely with a Plug cap 41 may be covered, which the nozzle 32 closely surrounds up to the handle 7 and covers the nozzle 30.

Zur Inbetriebnahme wird die durch Reibung oder Federrastung festgesetzte Kappe 41 abgezogen. Mit dem Daumen wird innerhalb der Kappe 34 gegen die Handhabe 6 und mit weiteren Fingern derselben Hand beiderseits des Stutzens 32 in entgegengesetzter Richtung gegen die Handhabe 7 mit steigender Kraft gedrückt, bis die Hemmung 38 ausrückt. Dadurch wird das Ende des Stößels 25 ohne Berührung der Membran 20 schlagartig unter Beschleunigung gegen die Endfläche 24 gefahren, so daß im weiteren Verlauf der Kolben 16 gegen den Körper 8 und die Schneide 19 bei geschlossener Membran 20 bewegt und der Druck in der Kammer 12 erhöht wird. Sobald die untere Stirnfläche der Membran 20 an der Schneide 19 ankommt, beginnt diese die Membran 20 zu durchdringen, bis sie nur geringfügig über die obere Stirnfläche der Membran 20 vorsteht, so daß nur noch der Einlaß 17, nicht aber der Auslaß 18, in der Kammer 12 liegt.The start-up is caused by friction or spring engagement fixed cap 41 pulled off. With the thumb is inside the cap 34 against the handle 6 and others Fingers of the same hand on both sides of the neck 32 in opposite directions Direction against the handle 7 with increasing Press force until the escapement 38 disengages. This will make it End of the plunger 25 suddenly without touching the membrane 20 accelerated against the end face 24 so that in the further course of the piston 16 against the body 8 and the Cutting 19 moves with the membrane 20 closed and the pressure is increased in the chamber 12. Once the lower face the membrane 20 arrives at the cutting edge 19, this begins the To penetrate membrane 20 until they are only slightly above the protrudes the upper end face of the membrane 20, so that only inlet 17, but not outlet 18, in chamber 12 lies.

Durch den nun außerhalb der Kammer 12 und innerhalb der oberen Vertiefung des Kolbens 16 liegenden Auslaß 18 wird das Medium in diese Vertiefung und dann in den Kanalabschnitt 27 gefördert, da das Fluid aus der Kammer 12 durch den Einlaß 17 am unteren Ende der Medienfüllung in die Kammer 11 eindringt und unter Vermischung das Medium nach oben in Richtung des Austrages aus der Düse 30 aus der Kammer 11 unmittelbar in den linearen Kanal 26, 27 herausreißt und ohne weitere Umlenkung bis in die Strömungseinrichtung 31 bzw. die Düse 30 fördert. Nach Anschlag des Kolbens 16 am Boden der Kammer 12 liegt der Einlaß 17 innerhalb des durch die untere Kolbenvertiefung gebildeten Raumes. Ist dieser Raum dabei durch die Stirn- bzw. Anschlagfläche des Kolbens 16 gegenüber der Kammer 12 abgedichtet, so wird der Fluidstrom schlagartig unterbrochen. Dieser Raum kann dabei aber auch mit der Kammer 12 verbunden bleiben, so daß aus dieser bis zum Druckausgleich Fluid nachströmt und die Kammer 11, wie auch die Kanalwege 26, 27, 30, 31, vom Medium vollständig freibläst.By now outside the chamber 12 and inside the upper recess of the piston 16 lying outlet 18 the medium into this depression and then into the channel section 27 promoted as the fluid from chamber 12 through the inlet 17 penetrates into the chamber 11 at the lower end of the media filling and mixing the medium upwards in the direction the discharge from the nozzle 30 from the chamber 11 immediately tears out in the linear channel 26, 27 and without further Deflection into the flow device 31 or the nozzle 30 promotes. After piston 16 stops at the bottom of chamber 12 the inlet 17 is within the through the lower piston recess formed space. Is this space through the Face or stop surface of the piston 16 relative to the Chamber 12 sealed, the fluid flow is abrupt interrupted. This room can also be used with the chamber 12 remain connected so that from this until pressure equalization Fluid flows and the chamber 11, as well as the Canal paths 26, 27, 30, 31, completely blown free from the medium.

In dieser gegenseitigen Endstellung der Einheiten 2, 3 hat die Handhabe 6 annähernd die untere Innenseite der Stirnwand 35 erreicht. Bei gesonderter Ausbildung ist der Kolben 16 dann mit dem Stößel 25 nicht wieder zurückziehbar, weil der Eingriff des Kolbens 16 in den Körper 8 eine Rückzugsicherung bildet. Die Einheit 2 kann trotzdem nach unten vom Stößel 25 abgezogen und aus der Kappe 34 und dem Stutzen 32 herausgezogen sowie ggf. durch eine neue Einheit 2 ersetzt werden. Bei zugfester Verbindung des Kolbens 16 mit dem Stößel 25 könnte dieser einen Rückhub in die Ausgangsstellung ausführen, wodurch die Kammer 12 durch einen geeigneten, ventilgesteuerten Einlaß wieder mit Luft gefüllt werden könnte. Der Stutzen 32 wird von der Außenseite, nämlich von der Handhabe 7 her, an der Kappe 24 und dem Körper 4, 13 montiert. Alle Bauteile, ggf. bis auf den Speicher 8, bestehen aus Kunststoff und können als Spritzgußteile hergestellt sein.In this mutual end position of the units 2, 3 has the handle 6 approximately the lower inside of the end wall 35 reached. With a separate design, the piston is 16 then with the plunger 25 not retractable because of Engagement of the piston 16 in the body 8 a retraction forms. The unit 2 can still down from the plunger 25th withdrawn and pulled out of the cap 34 and the nozzle 32 and possibly be replaced by a new unit 2. When the piston 16 is connected to the plunger 25 in a tensile connection this could make a return stroke to the starting position, whereby the chamber 12 by a suitable, valve-controlled Inlet could be refilled with air. The Stub 32 is from the outside, namely from the handle 7 ago, mounted on the cap 24 and the body 4, 13. All Components, possibly up to the memory 8, are made of plastic and can be made as injection molded parts.

Das untere Ende des Speichers 8 bzw. der Kammer 11 ist druckdicht mit einem Verschluß 40 verschlossen, welcher gemäß Fig. 1 einteilig mit dem Verschluß 15 ausgebildet sein kann und zweckmäßig bis nahe an den Einlaß 17 reicht. Beispielsweise kann das untere Ende des Mantels 8 als Schneide wirken, wenn der Speicher 8 zur Montage in den Boden 15 axial hineingedrückt sowie allein so durch Reibung am Innen- und Außenumfang festgelegt wird und dabei der innerhalb der Schneide liegende Teil des Bodens 15 als Verschluß 40 in den Speicher 8 eindringt.The lower end of the memory 8 or the chamber 11 is closed pressure-tight with a closure 40, which according to Fig. 1 can be integrally formed with the closure 15 and expediently extends to close to the inlet 17. For example the lower end of the jacket 8 can act as a cutting edge, when the memory 8 is pushed axially into the base 15 for assembly and just because of friction on the inner and outer circumference is set and the inside of the cutting edge lying part of the bottom 15 as a closure 40 in the memory 8 penetrates.

Die Achse der jeweiligen Öffnung 17 kann gemäß Fig. 1 rechtwinklig zur Achse 10 liegen. Sie kann aber auch in Austragrichtung gemäß Fig. 2 spitzwinklig zur Achse 10 schräg liegen. Dies gilt auch für die durch den Verschluß 40 gebildete, vom Auslaß 18 entfernte und an die Begrenzung der Öffnung 17 tangential anschließende Bodenfläche 42 des Speicheraumes, die auch ballig bzw. konvex gekrümmt sei kann. Gemäß Fig. 2 ist der Verschluß 40 durch einen vom Verschluß 15 gesonderten, vollständig innerhalb des Speichers 8 liegenden Bauteil gebildet, so daß der Verschluß 40 mit dem Speicher 8 vormontiert und dieser dann mit dem Körper 13 bzw. dem Boden 15 verbunden werden kann. Der Boden 14 kann auch vollständig innerhalb des Mantels 14 liegen und seine untere Endfläche kann mit derjenigen des Mantels 14 bzw. des Speichers 8 in einer Ebene vorgesehen sein.The axis of the respective opening 17 can be rectangular according to FIG. 1 to axis 10. But it can also in the discharge direction 2 obliquely to the axis 10 at an acute angle lie. This also applies to the formed by the closure 40, removed from outlet 18 and to the limit of Opening 17 tangentially adjoining bottom surface 42 of the Storage space that can also be crowned or convexly curved. 2, the closure 40 is by one of the closure 15 separate, completely within the memory 8 Component formed so that the closure 40 with the memory 8 pre-assembled and this with the body 13 or the Floor 15 can be connected. The bottom 14 can also lie completely within the jacket 14 and its lower End surface can with that of the jacket 14 or the memory 8 can be provided in one plane.

Gemäß Fig. 3 ist der Boden 42 des Speicherraumes durch ein vom Fluid in Austragrichtung zu durchströmendes Sieb gebildet, so daß das gespeicherte Medium nicht wie bei den Ausführungsformen nach den Fig. 1 und 2 die Öffnung 17 wie die Öffnung 18 verschließt, sondern der Einlaß 17 zwischen Verschluß 40 und Boden 42 in einen medienfreien Zwischenraum mündet, welcher vollständig innerhalb des Rohres 8 liegt. Das obere Ende des Rohres 8 ist hier spitzwinklig konisch verjüngt, so daß der Auslaß 18 und die Spitze 19 enger als der Speicherboden 42 bzw. das übrige Rohr 8 sind. Der Verschluß 40 könnte auch einteilig mit dem Rohr 8 ausgebildet sein, z.B. dadurch, daß das untere Rohrende durch Radialquetschung, Abwinkelung oder dergleichen verschlossen ist.3, the bottom 42 of the storage space is through a sieve to be flowed through by the fluid in the discharge direction, so that the stored medium is not as in the embodiments 1 and 2, the opening 17 as the Opening 18 closes, but the inlet 17 between Closure 40 and bottom 42 in a media-free space opens, which is completely within the tube 8. The the upper end of the tube 8 is here tapered at an acute angle, so that the outlet 18 and the tip 19 narrower than that Storage floor 42 and the rest of the tube 8 are. The closure 40 could also be formed in one piece with the tube 8, e.g. in that the lower end of the tube is caused by radial crushing, Bending or the like is closed.
