Die Erfindung betrifft eine Austragvorrichtung für Medien nach dem Oberbegriff des Patentanspruches 1. Das jeweilige Medium kann im Speicher- und/oder Austragzustand im wesentlichen beliebige Aggregatzustände aufweisen oder eine Mischung solcher Aggregatzustände bilden, die z. B. flüssig, pastös, gasförmig und/oder pulverförmig sein können, insbesondere derart, daß sie fließfähig sind. Eine solche Austragvorrichtung, die langgestreckt sein kann, wird zweckmäßig in dieser Längsrichtung in eine oder mehrere Gefäßöffnungen eines oder mehrerer Speichergefäße eingesetzt, je nachdem, ob nur ein einziges Medium, gesonderte Medien aus gesonderten Speicher- gefäßen oder aus einem Speichergefäß über gesonderte Kanäle gesonderte Medienchargen ausgetragen werden sollen.The invention relates to a discharge device for media according to the preamble of claim 1. The respective Medium can be stored and / or discharged in have any essential physical states or a Form mixture of such physical states, which, for. B. liquid, can be pasty, gaseous and / or powdery, in particular such that they are flowable. Such Discharge device, which can be elongated, is appropriate in this longitudinal direction in one or more vessel openings one or more storage vessels used, each after whether only one medium, separate media from separate storage vessels or from a storage vessel Separate media batches are carried out via separate channels should be.

Die Austragvorrichtung kann erfindungsgemäß mit etwa 3/4 der Länge ihres im Austragbetrieb gegenüber dem Speichergefäß im wesentlichen feststehenden Grundkörpers in das Speichergefäß hineinragen, während sie mit dem restlichen Teil dieser Länge, nämlich mit mehr als einem Viertel bzw. einem Drittel über die Außenseite des Speichergefäßes vorsteht. An das innere Ende des Grundkörpers kann noch ein in die genannte Gesamtlänge nicht einbezogener Saugkanal angesetzt, z. B. eingesteckt oder einteilig mit dem Grundkörper ausgebildet sein. Die genannte Gesamtlänge ist insbesondere auch durch den Abstand zwischen einem Ventilsitz eines Einlaßventiles und der äußeren Endfläche des Grundkörpers zu bestimmen, wobei dann der Grundkörper über die Außenseite des Gefäßes meist um mehr als ein Drittel dieser Gesamtlänge vorsteht.The discharge device can be used according to the invention with about 3/4 of the Length of their in discharge operation compared to the storage vessel in essential fixed body in the storage vessel protrude while remaining with the rest of this Length, namely with more than a quarter or a third protrudes beyond the outside of the storage vessel. To the inner end of the body can still be one in the mentioned Total length of suction channel not included, e.g. B. inserted or formed in one piece with the base body his. The total length mentioned is in particular also by the distance between a valve seat of an intake valve and to determine the outer end face of the base body, then the base body over the outside of the vessel usually protrudes by more than a third of this total length.

Dadurch wird die gesamte Austrageinheit gegenüber der Gesamtlänge des Speichergefäßes um das genannte Maß sowie um die Länge eines sich an das äußere Ende des Grundkörpers anschließenden Betätigungskopfes größer, wodurch ein beträchtlicher Längenunterschied besteht zwischen solchen Speichergefäßen, deren Gefäßöffnung zum Medienaustrag freizulegen bzw. zu öffnen ist und solchen, welche eine zusätzliche Austragvorrichtung mit einem gegenüber der Gefäßöffnung wesentlich verengten Austragkanal aufweisen. Solche Austragvorrichtungen können ein gegenüber dem Speichergefäß im wesentlichen lagefester Ausgießstutzen, eine Dosiereinrichtung für das Medium, eine Druckquelle zur Druckbeaufschlagung des Speichergefäßes, eine selbstansaugende Austrageinrichtung und/oder eine Austragpumpe sein, wobei das Einlaßventil gleichzeitig das Auslaßventil des Speicherbehälters bildet, bis zu welchem das Medium aus dem Speicherbehälter ohne Behinderung durch weitere Ventile o.dgl. strömen kann. Gegebenenfalls können auch zwei gesonderte Grundkörper bzw. Austragvorrichtungen zu einer Baueinheit zusammengefaßt und an ein und demselben Speichergefäß angeordnet werden.As a result, the entire discharge unit is compared to the total length of the storage vessel by the specified amount and by the Length of one adjoining the outer end of the base body Actuating head larger, creating a considerable Length difference exists between such Storage vessels, the vessel opening to expose the media discharge or to be opened and those that have an additional Discharge device with one opposite the vessel opening have significantly narrowed discharge channel. Such discharge devices can a compared to the storage vessel essential pouring spout, a dosing device for the medium, a pressure source for pressurization of the storage vessel, a self-priming discharge device and / or a discharge pump, the Inlet valve at the same time as the outlet valve of the storage tank forms up to which the medium from the storage container without obstruction by further valves or the like. can flow. If necessary, two separate Base body or discharge devices to form a structural unit summarized and arranged on one and the same storage vessel become.

Die jeweilige Gefäßöffnung des Speichergefäßes oder eines anderen Hohlkörpers kann durch einen Durchbruch in einer quer zur Einsetzrichtung liegenden Gefäßwandung, einen gegenüber einem Gefäßbauch verengten, mantelförmigen Gefäßhals und/oder durch ein Ende eines napfförmig offenen Gefäßes gebildet sein, das etwa von diesem ggf. geringfügig erweiterten Ende bis annähernd zu seinem Boden im wesentlichen konstante Innenweite aufweist. Für den Eingriff bzw. die Lagesicherung der Austragvorrichtung bildet das Speichergefäß Bezugsflächen, gegenüber welchen die Austragvorrichtung abzustützen ist. Solche Bezugsflächen können durch, die Gefäßöffnung an der Außenseite des Speichergefäßes umgebende, Flächen und/oder die Innenfläche der Gefäßöffnung bzw. des Speichergefäßes gebildet sein, wobei die jeweilige Bezugsfläche eine zur Längsrichtung quer liegende Stirnfläche und/oder eine um die Längsrichtung gekrümmte innere bzw. äußere Umfangs- oder Mantelfläche sein kann.The respective vessel opening of the storage vessel or one other hollow body can cross through a breakthrough opposite to the direction of the vessel wall a narrowed, vessel-shaped vessel neck and / or formed by one end of a cup-shaped open vessel be the end that may be slightly expanded from this essentially constant to approximately its bottom Has inside width. For the intervention or the securing of the position the discharge device, the storage vessel forms reference surfaces, against which to support the discharge device is. Such reference surfaces can pass through the vessel opening surfaces and / or surrounding the outside of the storage vessel the inner surface of the vessel opening or the storage vessel be formed, the respective reference surface one for Longitudinally transverse end face and / or one around Longitudinally curved inner or outer circumferential or Lateral surface can be.

Zur Lagesicherung der Austragvorrichtung gegenüber dem Speichergefäß in Längsrichtung und/oder zur Sicherung gegen Drehbewegungen des Grundkörpers der Austragvorrichtung gegenüber dem Speichergefäß sind Befestigungsmittel vorgesehen, welche nach dem Einsetzen der Austragvorrichtung in ihren Befestigungszustand gebracht und daher von der Außenseite der zusammengesetzten Einheit zugänglich sein sollten bzw. sowohl an der Außenseite der Austragvorrichtung als auch an der Außenseite des Speichergefäßes angreifen. Im Falle eines Krimpringes sollte dieser voneinander abgekehrte Seiten von aneinander abgestützten Ringflanschen des Grundkörpers und des Speichergefäßes umgreifen und auch den Außenumfang dieser Ringflansche umgreifen. Im Falle einer Steck- bzw. Schraubkappe sollte diese lagegesichert in den Außenumfang eines Gefäßhalses eingreifen und an den genannten Stirnflächen die Austragvorrichtung anliegen. Gleichzeitig sollten die Befestigungsmittel für die Befestigung gegenüber dem Grundkörper meist bewegbar sein, sofern sie sich beim Überführen in den Befestigungszustand nicht gegenüber dem Speichergefäß bewegen bzw. drehen sollen. To secure the position of the discharge device against the Storage vessel in the longitudinal direction and / or to secure against Rotational movements of the base body of the discharge device fastening means are provided opposite the storage vessel, which after inserting the discharge device in brought their attachment state and therefore from the outside should be accessible to the assembled unit or both on the outside of the discharge device and attack on the outside of the storage vessel. In the event of A Crimean ring should face away from each other of mutually supported ring flanges of the base body and embrace the storage vessel and also the outer circumference embrace this ring flange. In the case of a plug or Screw cap should secure this in the outer circumference of a neck of the vessel engage and on the end faces mentioned the discharge device. At the same time the fasteners for fastening against the The main body can usually be moved, provided that it moves during transfer in the attachment state not opposite the storage vessel should move or rotate.

Durch die EP-A-0 571 280 ist eine mit einem Sicherungsflansch befestigte Austragvorrichtung bekanntgeworden, bei welcher der Sicherungsflansch die Lüftungsöffnung gegenüber dem Hohlraum des Tragkörpers verschließt, obwohl der Innenmantel den Gehäusemantel der Austragvorrichtung mit Radialabstand umgibt. Der Sicherungsflansch ist auch wesentlich dickwandiger als der Gehäusemantel oder der Tragkörper, wobei der Sicherungsmantel radial nicht verengbar oder federnd ist, so dass er keine entsprechenden Querspannungen überträgt.Through EP-A-0 571 280 one with a securing flange fastened discharge device, in which the safety flange the ventilation opening opposite the Cavity of the support body closes, although the inner jacket the casing of the discharge device with radial spacing surrounds. The securing flange is also much thicker than the housing jacket or the support body, the Locking jacket is not radially constricting or resilient, so that it does not transmit any corresponding transverse stresses.

Gemäß der US-A-3 129 854 weist der Gehäusemantel am Umfang klappbare Rippen zur verspannten Abstützung am Innenumfang des Tragkörpers auf. Außerdem kann eine gesonderte Sicherungshülse für eine entsprechende radiale Spannung vorgesehen sein. Ein Belüftungssystem für den Tragkörper weist diese Ausbildung nicht auf.According to US-A-3 129 854, the housing jacket has on the circumference foldable ribs for braced support on the inner circumference of the supporting body. In addition, a separate locking sleeve provided for a corresponding radial tension his. A ventilation system for the support body has this Training not on.

Der Erfindung liegt des weiteren als Aufgabe zugrunde, eine Austragvorrichtung zu schaffen, bei welcher Nachteile bekannter Ausbildungen bzw. ggf. der beschriebenen Art vermieden sind und die insbesondere bei einfacher Ausbildung eine wesentliche Verkürzung der Gesamtlänge der zusammengesetzten Austrageinheit erlaubt.The invention is also based on the object of a To create discharge device, in which disadvantages are known Training or possibly the type described avoided are and especially when it comes to simple training significant reduction in the total length of the composite Discharge unit allowed.

Erfindungsgemäß sind die Merkmale nach Patentanspruch 1 vorgesehen. Es sind Mittel vorgesehen, um die Austragvorrichtung in der jeweils geeigneten Ausrichtung am Hohlkörper o.dgl. zu halten. Z.B. kann die Austragvorrichtung in mindestens einem Funktionszustand gegenüber bekannten Ausbildungen wesentlich tiefer im Gefäß versenkt in Längs-, Quer- und/oder Umfangsrichtung lagegesichert bzw. gegenüber dem Gefäß oder einer anderen Aufnahme im wesentlichen lagestarr gehaltert werden. Funktionsstellungen können Austragstellungen sein, bei welchen ein Austrag möglich ist, oder sie können Ruhestellungen sein, bei welchen ein Austrag verhindert ist, so daß für einen Austrag zunächst eine Überführung in eine Austragstellung erforderlich ist.According to the invention, the features according to claim 1 intended. Means are provided for the discharge device in the appropriate orientation on the hollow body or the like. to keep. For example, can the discharge device in at least a functional state compared to known training much deeper in the vessel sunk in longitudinal, transverse and / or Circumferential direction secured or relative to the vessel or another recording held essentially rigid become. Functional positions can be discharge positions, where a discharge is possible, or they can have rest positions in which discharge is prevented, so that for a discharge first a transfer to a Discharge is required.

Z. B. kann der Grundkörper der Austragvorrichtung so tief in dem Speichergefäß versenkt liegen, daß er über dieses nur noch mit weniger als einem Viertel bzw. weniger als einem Zehntel der genannten Gesamtlänge vorsteht, wobei zwischen diesen beiden Werten je nach den Erfordernissen jeder ganzzahlige Quotient vorteilhaft sein kann. Insbesondere steht der Grundkörper über die die Gefäßöffnung umgebende Außenseite des Speichergefäßes zweckmäßig nur um die Dicke einer einlagigen oder mehrlagigen Wandung vor, deren Wandungslagen unmittelbar aneinander anliegen, wobei eine Wandungslage durch eine Dichtung gebildet sein kann. Diese Dicke liegt zweckmäßig unter 3 bzw. 2 oder 1 mm, bzw. entspricht sie etwa der Wandungsdicke mindestens eines frei innerhalb des Speichergefäßes liegenden Gehäuses oder Mantels der Austragvorrichtung.For example, the base body of the discharge device can be so deep the storage vessel are sunk that he only about this even less than a quarter or less than one Tenths of the total length protrudes, with between These two values are integers depending on the requirements Quotient can be advantageous. In particular it says the base body over the outside surrounding the vessel opening of the storage vessel expedient only by the thickness of one single-layer or multi-layer wall, the wall layers abut directly against each other, with a wall layer can be formed by a seal. This thickness is expediently less than 3 or 2 or 1 mm, or corresponds approximately the wall thickness of at least one freely within the storage vessel lying housing or casing of the discharge device.

Weist die Austragvorrichtung einen für den Austrag zu betätigenden, z. B. etwa in der genannten Längsrichtung zu verschiebenden Betätigungskopf o.dgl. auf, so kann dieser in der jeweiligen Funktionsstellung der Austragvorrichtung bzw. in mindestens einer seiner Ruhe- oder Arbeitsstellungen mit dem größten Teil seiner Länge über die genannte Außenseite des Speichergefäßes vorstehen, bzw. in das Speichergefäß hineinragen, wobei auch eine im wesentlichen vollständig im Speichergefäß versenkte Lage des Betätigungskopfes denkbar ist.If the discharge device has one to be operated for the discharge, z. B. to be shifted approximately in said longitudinal direction Actuating head or the like on, this can in the respective functional position of the discharge device or in at least one of his resting or working positions with the most of its length over the named outside of the Protrude storage vessel or protrude into the storage vessel, also being essentially completely in the storage vessel recessed position of the actuating head is conceivable.

Die Sicherungsmittel weisen zweckmäßig Mittel zur formschlüssigen Längsabstützung der Austragvorrichtung gegenüber dem Speichergefäß auf, wobei diese Abstützmittel bzw. deren Stützflächen etwa in der Ebene des äußeren Endes des Grundkörpers liegen und/oder mit diesem verbunden sein können, zweckmäßig jedoch die Verbindung demgegenüber in Längsrichtung versetzt ist, z. B. in Richtung zum inneren Ende des Grundkörpers. Die Sicherungsmittel können an der Außenund/oder Innenseite des Gefässes liegen, und dieses braucht im Innern keine Öffnung, Vertiefung oder Nut für den Eingriff der Sicherungsmittel. Hierfür ist auch eine Aufweitung des Gefässes nicht erforderlich, obwohl das Vorsehen einer Vertiefung denkbar ist.The securing means expediently have means for positive locking Longitudinal support of the discharge device compared to the Storage vessel on, these support means or their Support surfaces approximately in the plane of the outer end of the base body lie and / or can be connected to it, In contrast, however, the connection is expedient in the longitudinal direction is offset, e.g. B. towards the inner end of the Body. The securing means can on the outside and / or Lie inside the vessel, and this needs no opening, recess or groove for the intervention inside the means of protection. This is also an expansion of the Vessel not required, although providing one Deepening is conceivable.

Die Sicherungsmittel können Zentriermittel zur ggf. radial vorgespannten bzw. radialspielfreien Anlage an der Innenseite des Speichergefäßes aufweisen, welche zweckmäßig durch mindestens einen Längsschenkel bzw. Mantel gebildet sind, der im Axialabstand von den axial wirkenden Abstützmitteln an den Grundkörper anschließt. Die Zentriermittel können auch für die Anlage an der Außenseite des Speichergefäßes vorgesehen sein, wobei diese Zentriermittel zweckmäßig weniger lang als die inneren Zentriermittel sind bzw. in Richtung zum inneren Ende des Grundkörpers weniger weit vorstehen als die inneren Längsverbindungen bzw. Zentriermittel.The securing means can be centering means for radial, if necessary preloaded or radial play-free system on the inside of the storage vessel, which expediently by at least one longitudinal leg or jacket are formed, the at an axial distance from the axially acting support means to the Basic body connects. The centering means can also be used for the system is provided on the outside of the storage vessel be, these centering means are advantageously less than the inner centering means are towards the inner one Protrude less far from the end of the body than the inner ones Longitudinal connections or centering means.

Zwischen den inneren Zentriermitteln bzw. einem in die Gefäßöffnung oder das Speichergefäß eingreifenden Mantel und dem Außenumfang des Grundkörpers kann eine zu dessen äußerem Ende bzw. nach außen offene Öffnung oder Vertiefung gebildet sein, in welche z. B. der Betätigungskopf in mindestens einer seiner Betriebslagen eingreifen kann. Der zweckmäßig dicht geschlossene Boden dieser Öffnung liegt wie auch der Längsschenkel innerhalb des Gefäßes bzw. des Gefäßhalses und kann gleichzeitig die genannte Verbindung zwischen den Sicherungsmitteln und dem Grundkörper bilden.Between the inner centering means or one in the vessel opening or the jacket engaging the storage vessel and the outer circumference of the base body can one to the outer End or outward opening or recess formed be in which z. B. the actuating head in at least one can intervene in its operating The appropriately tight closed bottom of this opening lies like the longitudinal leg inside the vessel or neck of the vessel and can at the same time the connection between the securing means and form the base body.

Die Sicherungsmittel sind vorteilhaft so ausgebildet, daß durch sie keine oder keine wesentliche Radialkraft auf den Grundkörper ausgeübt wird, so daß dieser durch die radialen Sicherungskräfte nicht belastet wird. Z. B. können die inneren Verbindungs- oder Zentriermittel in demjenigen Bereich von Radialbelastungen durch den Innenumfang des Speichergefäßes frei bzw. radial im wesentlichen spannungsfrei sein, in welchem sie mit dem Grundkörper verbunden sind. Des weiteren können die inneren Zentriermittel so profiliert sein, daß eventuelle Radialbelastungen durch das Speichergefäß nicht auf den Grundkörper übertragen, sondern durch federnde Nachgiebigkeit so aufgefangen werden, daß nur die Zentriermittel, nicht aber der Grundkörper verformt werden. Die Zentriermittel können zu diesem Zweck mit dem Grundkörper im Querschnitt ein U-Profil mit einem radial äußeren und einem radial inneren Schenkel bilden, wobei einer dieser Schenkel, insbesondere der äußere Schenkel nicht durchgehend geradlinig sondern an seiner Innen- und/oder Außenseite abgewinkelt bzw. gekrümmt ist.The securing means are advantageously designed so that through it no or no significant radial force on the Basic body is exercised so that this through the radial Security forces are not charged. For example, the internal connecting or centering means in one Range of radial loads due to the inner circumference of the Storage vessel free or radially essentially free of tension be in which they are connected to the main body are. Furthermore, the inner centering means can be profiled that any radial loads caused by the Do not transfer the storage vessel to the base body, but rather be absorbed by resilient compliance so that only the centering means, but not the base body, are deformed become. For this purpose, the centering means can be used with the Base body in cross section a U-profile with a radial form outer and a radially inner leg, one this leg, especially the outer leg, does not straight through but on its inside and / or Outside is angled or curved.

Weist die Austragvorrichtung einen von einem Hauptgehäuse gesonderten Gehäuseabschluß am äußeren Ende o.dgl. auf, der z. B. das äußere Ende des Grundkörpers bildet, so können die Sicherungsmittel tragend mit diesem Gehäuseabschluß und nur über diesen Gehäuseabschluß tragend mit dem Hauptgehäuse verbunden sein. Die Sicherungsmittel bilden zweckmäßig gemeinsam mit dem Gehäuseabschluß eine Montageeinheit zur Befestigung am Hauptgehäuse bzw. mit dem Hauptgehäuse eine Montageeinheit zur Befestigung am Gefäß. Im Montagezustand können dabei die Sicherungsmittel im wesentlichen lagefest gegenüber dem Gehäuseabschluß bzw. dem Gehäuse vorgesehen und mit diesem auch einteilig ausgebildet sein.The discharge device has one of a main housing separate housing termination at the outer end or the like. on the z. B. forms the outer end of the base body, so the Securing means with this housing closure and only bearing with this main closure with the main housing be connected. The securing means are appropriate together with the housing end a mounting unit for Attachment to the main housing or with the main housing Mounting unit for attachment to the vessel. In the assembled state can the securing means essentially stable provided against the housing end or the housing and can also be formed in one piece with this.

Die Sicherungsmittel sind zweckmäßig als Steckmittel ausgebildet, welche im wesentlichen ausschließlich durch eine lineare Steckbewegung etwa parallel zur Längsrichtung der Austragvorrichtung in ihren endgültigen Sicherungseingriff mit dem Speichergefäß gebracht werden können, anstatt eine Drehbewegung über einen Teil einer Volldrehung oder eine bzw. mehrere Volldrehungen zu benötigen. Die Sicherungsmittel können daher vollständig frei von Gewinden, Bajonettverschluß-Gliedern, Schnappgliedern oder ähnlichen Sicherungsprofilierungen sein, obgleich auch deren Anwendung denkbar ist. Dies gilt auch für konische Abstützflächen, insbesondere solche zur Abstützung an der Innenseite des Speichergefäßes bzw. des Gefäßhalses, wobei diese Abstütz- bzw. Zentrierflächen im Bereich der Anlage am Speichergefäß etwa parallel zur Einsetzrichtung bzw. zur Gegenfläche des Speichergefäßes liegen und demgegenüber höchstens um denjenigen Winkel von weniger als 1° oder 2° schräg vorgesehen sind, welcher als Entformungswinkel bei der Herstellung in einer Gußform üblich ist.The securing means are expediently designed as plug-in means, which essentially consists exclusively of a linear plug movement approximately parallel to the longitudinal direction of the Discharge device in its final securing engagement can be brought with the storage vessel instead of one Rotary movement over part of a full rotation or one or need several full turns. The means of protection can therefore be completely free of threads, bayonet lock links, Snap links or similar securing profiles be, although their application is also conceivable is. This also applies to conical support surfaces, in particular those for support on the inside of the storage vessel or the neck of the vessel, these support or centering surfaces in the area of the system around the storage vessel parallel to the direction of insertion or to the counter surface of the storage vessel lie and in contrast at the most around the one Angles of less than 1 ° or 2 ° are provided obliquely, which is used as a draft angle during production in one Mold is common.

Unabhängig von der beschriebenen Ausbildung kann die Austragvorrichtung auch Verschlußmittel zum im wesentlichen dichten Verschluß der Gefäßöffnung aufweisen, die so ausgebildet sind, wie anhand der Sicherungsmittel beschrieben. Diese Verschlußmittel können mit den Sicherungmitteln zerstörungsfrei lediglich durch eine Abzugbewegung o.dgl. lösbar in den Behälter eingreifen, so daß sie gemeinsam mit der Austragvorrichtung vollständig von dem Behälter abgenommen werden können. Zweckmäßig sind die Verschlußmittel und die Sicherungsmittel durch ein und dieselben Mittel gebildet.Regardless of the training described, the discharge device also sealing means for essentially sealing Have closure of the vessel opening, which is formed are as described with the aid of the securing means. These closures can be used non-destructively with the securing means or the like only by a trigger movement. detachable in the Intervene containers so that they together with the discharge device completely removed from the container can. The closure means and the securing means are expedient formed by one and the same means.

Die erfindungsgemäße Ausbildung ist insbesondere für Austragvorrichtungen geeignet, wie sie z. B. in der EP-A-0 530 785 oder der DE-A-3 545 409 beschrieben sind, auf deren Merkmale und Wirkungen zum Zwecke der Einbeziehung in die vorliegende Erfindung bezug genommen wird. Die Austragvorrichtung kann dabei so tief in das Speichergefäß versenkt sein, daß die Begrenzung ihrer durch den Grundkörper bzw. ein Steigrohr oder einen flexiblen Steigschlauch gebildeten Einlaßöffnung unmittelbar benachbart zum Gefäßboden liegt oder an diesem Gefäßboden in einem Bereich abgestützt ist, der gegenüber den übrigen Bodenbereichen vertieft ist, so daß eine vollständige Entleerung des Speichergefäßes gewährleistet ist.The training according to the invention is particularly for discharge devices suitable as z. B. in EP-A-0 530 785 or DE-A-3 545 409 are described, on their features and effects for the purpose of inclusion in the present Invention is referred to. The discharge device can be so deep in the storage vessel that the Limiting them through the base body or a riser pipe or a flexible riser formed inlet opening is immediately adjacent to or at the bottom of the vessel Vessel bottom is supported in an area that is opposite the remaining floor areas is recessed so that a complete Emptying of the storage vessel is guaranteed.

Unabhängig von der beschriebenen Ausbildung kann auch eine Abdeckung bzw. ein zerstörungsfrei leicht lösbarer Verschluß für die Austragvorrichtung oder deren Medienauslaß vorgesehen sein, der sowohl zur unmittelbaren Verbindung mit der Austragvorrichtung bzw. den Sicherungs- oder Verschlußmitteln als auch dafür geeignet ist, unmittelbar mit einem Gefäß oder Hohlkörper verbunden zu werden, wenn dieser nicht mit einer Austragvorrichtung versehen ist. Die Abdeckung ist in Abdecklage gegenüber der Austragvorrichtung so gesichert, daß für diese Sicherung das Speichergefäß nicht erforderlich ist, z. B. dadurch, daß die Abdeckung dann ausschließlich in die Austragvorrichtung bzw. die Sicherungsmittel mit Lage-Sicherungsflächen eingreift und gegenüber dem Speichergefäß berührungsfrei sein kann. Zum unmittelbaren Verschluß eines Speichergefäßes übergreift die Abdeckung zweckmäßig deren Hals am Außenumfang.Regardless of the training described, one can Cover or a non-destructive, easily removable closure provided for the discharge device or its media outlet be both for direct connection to the discharge device or the securing or closing means is also suitable, directly with a vessel or Hollow body to be connected if this is not with a Discharge device is provided. The cover is in the cover position secured to the discharge device so that for this backup the storage vessel is not required, e.g. B. in that the cover then only in the Discharge device or the securing means with position-securing surfaces engages and opposite the storage vessel can be non-contact. For the immediate closure of a Storage vessel appropriately overlaps the cover Neck on the outer circumference.

Unabhängig von der beschriebenen Ausbildung ist auch eine Montageanordnung für Lage-Sicherungsmittel vorgesehen, welche zwei Bauteile leicht bzw. zerstörungsfrei lösbar miteinander verbinden. Diese Sicherungsmittel weisen zwei lösbar ineinander greifende Sicherungsglieder auf, von denen das eine dem einen Bauteil und das andere dem anderen, abnehmbaren Bauteil zugeordnet ist. Diese Sicherungsglieder können in ihrer Sicherungslage an einem der Bauteile, insbesondere am abnehmbaren Bauteil montiert werden, wonach dieser Bauteil am anderen Bauteil in seiner Sicherungslage angebracht wird. Das diesem anderen Bauteil zugehörige Sicherungsglied wird dabei in Eingriff mit diesem Bauteil gebracht und aufgrund der Montagebewegung gegenüber diesem Bauteil in einer Lage so gesichert, daß es sich beim Abnehmen des abnehmbaren Bauteiles nicht mehr vom zugehörigen Bauteil löst, sondern das Sicherungsglied des abnehmbaren Bauteiles freigibt. Dadurch ist eine sehr einfache Montage gewährleistet.Regardless of the training described is also one Mounting arrangement for position securing means provided which two components easily or non-destructively detachable with each other connect. These securing means releasably have two in one another engaging security links, one of which is the one component and the other the other, removable component assigned. These fuse links can be in their Secured position on one of the components, especially on the removable one Component are assembled, after which this component on other component is attached in its securing position. The this other component associated fuse link brought into engagement with this component and due to the assembly movement secured against this component in a position so that it is when removing the removable component no longer detaches from the associated component, but the securing member releases the removable component. This is ensures a very simple assembly.

Die Austragvorrichtung 1 ist nach Art einer Tauchpumpe im wesentlichen vollständig versenkt in einem Tragkörper bzw. Speichergefäß so angeordnet, daß das Pumpen-Gehäuse im wesentlichen vollständig innerhalb des Innenraumes des Speichergefäßes 2 liegt. Dieses Speichergefäß 2 weist eine im wesentlichen achssymmetrische kreisrunde Gefäßöffnung 3 auf, welche an der Außenseite des Speichergefäßes 2 von einer zu ihrer Mittelachse quer bzw. rechtwinklig liegenden, ringförmigen Außen-Stirnfläche 4 umgeben ist. Ferner ist sie im Radialabstand nach außen von einer Außen-Umfangsfläche 5 umgeben, die durch einen vorstehenden Ringwulst gebildet ist und unmittelbar bzw. über eine Anphasung oder Abrundung in die Stirnfläche 4 übergeht. In dieser Weise geht auch die die Gefäßöffnung 3 begrenzende Innen-Umfangsfläche 6 in die Stirnfläche 4 über, wobei diese Umfangsfläche 6 durch einen radial nach innen vorspringenden Ringwulst gebildet ist und etwa im gleichen Axialabschnitt wie die Umfangsfläche 5 liegt. Die Gefäßöffnung 3 und die Flächen 4 bis 6 sind durch einen Gefäßhals 7 gebildet, welcher an seinem von der Gefäßöffnung 3 abgekehrten Ende in einen wesentlich erweiterten Gefäßbauch 8 von etwa gleicher Wandungsdicke wie der Gefäßhals 7 übergeht. Dieser Gefäßbauch 8 begrenzt mit einem Teil des Gefäßhalses 7 den nach außen im Ausgangszustand im wesentlichen medien- bzw. druckdicht geschlossenen Speicherraum 9 zur Aufnahme des auszutragenden Mediums. Der Gefäßhals 7 kann sehr kurz ausgebildet sein und eine Länge von nur etwa 2/10 seiner Außenweite haben, wobei die Umfangsflächen 5, 6 um weniger als die Hälfte kürzer sind.The discharge device 1 is in the manner of a submersible pump essentially completely sunk in a supporting body or Storage vessel arranged so that the pump housing in essentially completely within the interior of the Storage vessel 2 is. This storage vessel 2 has a essentially axially symmetrical circular vessel opening 3, which on the outside of the storage vessel 2 from one to their central axis lying transversely or at right angles Outside end face 4 is surrounded. Furthermore, it is in the Radial distance outward from an outer peripheral surface 5 surrounded, which is formed by a protruding ring bead and immediately or via a chamfer or rounding in the end face 4 merges. This is also how it works Vessel opening 3 delimiting inner peripheral surface 6 in the End face 4 over, this peripheral surface 6 by a radially inwardly projecting annular bead is formed and approximately in the same axial section as the peripheral surface 5 lies. The vessel opening 3 and the surfaces 4 to 6 are through a vessel neck 7 is formed, which at its from the vessel opening 3 turned end into a much expanded Vascular abdominal wall 8 of approximately the same wall thickness as the neck of the vessel 7 passes. This vascular belly 8 delimits with one part of the vessel neck 7 to the outside in the initial state in essential media or pressure-tight closed storage space 9 for receiving the medium to be discharged. The neck of the vessel 7 can be made very short and only about a length 2/10 of its outer width, the peripheral surfaces 5, 6 are shorter than half.

Zur Befestigung der Austragvorrichtung 1 sind Sicherungsmittel 10 vorgesehen, die wie die Austragvorrichtung 1, die Gefäßöffnung 3, die Flächen 4 bis 6, der Gefäßhals 7 und der Gefäßbauch 8 etwa in einer Mittel- bzw. Längsachse 11 liegen können.Securing means are used to fasten the discharge device 1 10 provided, like the discharge device 1, the vessel opening 3, the surfaces 4 to 6, the vessel neck 7 and the Vascular abdominals 8 lie approximately in a central or longitudinal axis 11 can.

Die Austragvorrichtung 1 weist einen im wesentlichen lagestarren, am zugehörigen Befestigungsabschnitt 7 des Speichergefäßes 2 befestigten und hohlen Grundkörper 12 auf, der das genannte Gehäuse bildet und entlang der Längsachse 11 langgestreckt ist, nämlich gegenüber seiner größten Außenweite mindestens 2- bis 3-fach länger ist. Der Grundkörper 12 ist aus zwei Grundkörperteilen, nämlich einem längeren Gehäuseteil 13 und einem kürzeren Verschlußteil 14 zusammengesetzt, wobei der Gehäuseteil 13 über das innere Ende des Verschlußteiles 14 mit dem größten Teil seiner Länge bzw. mehr als 3/4 davon berührungsfrei in den Speicherraum 9 vorsteht. Mit Abstand innerhalb des inneren Endes des Verschlußteiles 14 begrenzt der Gehäuseteil 13 mit der Innenseite seiner außen an den Speicherraum 9 angrenzenden Wandung einen Medien- bzw. Druckraum 15, der als Pumpenkammer vorgesehen und im Querschnitt wenigstens teilweise ringförmig ist.The discharge device 1 has a substantially rigid position, on the associated fastening section 7 of the storage vessel 2 attached and hollow base body 12, which the mentioned housing forms and elongated along the longitudinal axis 11 compared to its largest outside width is at least 2 to 3 times longer. The base body 12 is from two basic body parts, namely a longer housing part 13 and a shorter closure part 14, the housing part 13 over the inner end of the closure part 14 with most of its length or more than 3/4 of which protrudes into the storage space 9 without contact. With Distance within the inner end of the closure member 14 limits the housing part 13 with the inside of its outside a media or wall adjacent to the storage space 9 Pressure chamber 15, which is provided as a pump chamber and in cross section is at least partially annular.

Zur Betätigung der Austragvorrichtung so, daß Medium gefördert bzw. ausgetragen wird, ist eine Betätigungseinheit 16 vorgesehen, die zur manuellen Betätigung teilweise außerhalb des Grundkörpers 12 und des Speichergefäßes 2 liegt, bzw. im Bereich der Gefäßöffnung 3 oder durch diese hindurch manuell zugänglich ist. Die Betätigungseinheit 16 weist einen schlanken, langgestreckten Schaft 17 auf, welcher den Grundkörper 12 bzw. beide Gehäuseteile 13, 14 wenigstens teilweise durchsetzt und innerhalb diesen einen Schieber 18 trägt. Dieser ist, als Pumpkolben 18 abgedichtet, entlang des Innenumfanges des Druckraumes 15 verschiebbar geführt, den er an seiner vorderen Stirnfläche begrenzt. Vom Druckraum 15 führt ein Auslaßkanal 19 durch den Schaft 17 bzw. zu dem Grundkörper 12 in einen Betätigungskopf 20, welcher am äußeren, im wesentlichen außerhalb des Grundkörpers 12 liegenden Ende des Schaftes 17 lediglich durch eine lineare Steck- und/oder Rastverbindung abzuggesichert, befestigt ist. Der Betätigungskopf 20, der zur manuellen Betätigung zugänglich ist, weist den ins Freie führenden Auslaß 21 für das Medium auf, der in diesem Fall durch einen radial nach außen gerichteten und vollständig versenkt im Betätigungskopf 20 liegenden Düsenkörper bzw. eine Zerstäuberdüse gebildet ist. Diese liegt zwischen den Enden des Betätigungskopfes 20.To actuate the discharge device so that medium is conveyed is carried out, an actuation unit 16th provided for manual operation partially outside of the base body 12 and the storage vessel 2, or in Area of the vessel opening 3 or through this manually is accessible. The actuation unit 16 has a slim, elongated shaft 17 on which the base body 12 or both housing parts 13, 14 at least partially penetrated and within this carries a slide 18. This is sealed as a pump piston 18, along the inner circumference of the pressure chamber 15 guided, which he at his front face limited. Introduces from the pressure chamber 15 Outlet channel 19 through the shaft 17 or to the base body 12 into an actuating head 20, which on the outside, essentially outside of the base body 12 end of the Shaft 17 only by a linear plug and / or Latching connection is secured, secured. The actuating head 20, which is accessible for manual actuation, has the outlet 21 leading to the outside for the medium, which in this case is directed radially outwards and completely sunk in the actuating head 20 Nozzle body or an atomizer nozzle is formed. This lies between the ends of the actuating head 20.

Die Schieber- bzw. Kolbeneinheit aus Schaft 17, Schieber 18 und einem in diesen eingesetzten Kernkörper bildet den an den Druckraum 15 angrenzenden, im Querschnitt ringförmigen Abschnitt des Auslaßkanales 19, der zwischen dem Innenumfang des manschettenförmigen Schiebers 18 und dem Außenumfang des Kernkörpers liegt. Ferner bildet diese Kolbeneinheit ein innerhalb des Schiebers 18 liegendes Auslaßventil 22, das in Abhängigkeit vom Verschiebeweg des Schiebers 18 und/oder vom Druck im Druckraum 15 rückfedernd öffnet, durch eine ringförmige Schließfläche am Innenumfang des Schiebers 18 sowie eine Gegenfläche am Außenumfang des Kernkörpers gebildet ist und das mit diesem Ventilverschluß das vordere Ende der Druckkammer 15 bzw. das hintere Ende des Auslaßkanales 19 bestimmt. The slide or piston unit made of shaft 17, slide 18 and a core body used in this forms the to the Pressure chamber 15 adjacent, annular section of the outlet channel 19, which is between the inner circumference of the cuff-shaped slider 18 and the outer circumference of the Core body lies. This piston unit also constitutes Exhaust valve 22 located within the slide 18, which in Dependence on the displacement of the slide 18 and / or on Pressure in the pressure chamber 15 opens resiliently, by an annular Closing surface on the inner circumference of the slide 18 and one Counter surface is formed on the outer circumference of the core body and that with this valve closure the front end of the pressure chamber 15 or the rear end of the outlet channel 19 is determined.

Durch eine nach außen gerichtete Längsbewegung des Schiebers 18 gegenüber dem Schaft 17 bzw. dem an diesem befestigten Kernkörper öffnet das Ventil gegen die Kraft einer Ventilfeder so, daß es in der entgegengesetzten Richtung unter Federkraft wieder schließt.By an outward longitudinal movement of the slide 18 relative to the shaft 17 or the one attached to it The core body opens the valve against the force of a valve spring so that it is under in the opposite direction Spring force closes again.

In dem nach außen an die Dichtfläche des Schiebers 18 anschließenden und an dessen Außenumfang angrenzenden Raum des Grundkörpers 12 ist ein Lüftungsventil 23 vorgesehen, das bei Ausgangsstellung der Austragvorrichtung 1 medien- bzw. druckdicht geschlossen und in jeder anderen Stellung geöffnet ist, um durch den Grundkörper 12 bzw. entlang des Schaftes 17 einen Druckausgleich zwischen dem Speicherraum 9 und der Außenatmosphäre herzustellen. Der Verschlußteil 14 weist einen in das Innere des Gehäuseteiles 13 eingreifenden Hülsenansatz auf, dessen Ende den Ventilsitz bildet, während der Ventilkörper durch den Außenumfang des Schiebers 18 gebildet ist. Der das Lüftungsventil 29 aufweisende und gegenüber dem Druckraum 15 abgedichtete Lüftungsraum ist über mindestens eine Öffnung in der Wandung des Gehäuseteiles 12 zum Speicherraum 9 offen.In the outwardly adjoining the sealing surface of the slide 18 and on the outer periphery adjoining space of the Base body 12, a ventilation valve 23 is provided, which at Starting position of the discharge device 1 media- or pressure-tight is closed and open in any other position, around through the base body 12 or along the shaft 17 a pressure equalization between the storage space 9 and the To create an outside atmosphere. The closure part 14 has one engaging in the interior of the housing part 13 Sleeve approach, the end of which forms the valve seat while the valve body through the outer periphery of the slide 18th is formed. The having the ventilation valve 29 and ventilation space sealed off from the pressure chamber 15 is over at least one opening in the wall of the housing part 12 open to storage room 9.

Innerhalb des Speicherraumes 9 weist die Austragvorrichtung 1 einen Medien-Einlaß 24 in Form einer nach innen gerichteten Öffnung im Grundkörper 12 auf, die zweckmäßig durch eine Stirnöffnung gebildet ist. An diesen Einlaß 24 kann je nach Länge des Speicherraumes 9 eine Steigleitung 25, z. B. ein flexibler bzw. elastischer Schlauch, anschließen, dessen vom Grundkörper 12 entferntes Ende dann den Übertritt bildet, in welchem das Medium aus dem Speicherraum 9 in die Austragvorrichtung 1 eintritt. Innerhalb des Grundkörpers 12 bzw. des Gehäuseteiles 13 ist ein druckabhängig arbeitendes Einlaßventil 26 vorgesehen, das am inneren Ende des Druckraumes 15 liegt bzw. mit seinem Ventilsitz dieses innere Ende bildet. The discharge device 1 has inside the storage space 9 a media inlet 24 in the form of an inward direction Opening in the base body 12, which is expedient by a Forehead opening is formed. Depending on this inlet 24 Length of the storage space 9 a riser 25, z. B. a flexible or elastic hose, connect from the Base 12 distal end then forms the transition, in which the medium from the storage space 9 in the discharge device 1 occurs. Within the base body 12 or Housing part 13 is a pressure-dependent inlet valve 26 provided at the inner end of the pressure chamber 15 lies or forms this inner end with its valve seat.

Das vom Auslaß 21 entfernte oder innerhalb des Speicherraumes 9 liegende Ende des Grundkörpers 12 bildet dessen inneres Ende 28, während das davon entfernte Ende das äußere Ende 27 bildet und durch die freie äußere Stirnfläche des Gehäuses 12 bzw. des Verschlußteiles 14 gebildet ist. Nach außen bedeutet daher zum Auslaß 21, zum äußeren Ende 27 bzw. zur Gefäßöffnung 3 hin, und nach innen bedeutet zum inneren Ende 28, zum Gefäßboden bzw. zum Gefäßraum 9 hin.That remote from the outlet 21 or within the storage space 9 lying end of the base body 12 forms its interior End 28, while the distal end is the outer end 27 forms and through the free outer end face of the housing 12th or the closure member 14 is formed. Outward means therefore to the outlet 21, to the outer end 27 or to the vessel opening 3 towards, and inward to the inner end means 28 to Vessel bottom or towards the vessel space 9.

Der Gehäuseteil 13 ist vom inneren Ende in den am Außenumfang weiteren Verschlußteil 14 eingesetzt, innerhalb von diesem und mit diesem über eine Steck- bzw. Schnappverbindung verbunden, steht über das äußere Ende 27 nicht vor und ist am Außenumfang seines eingesetzten Längsabschnittes von einem äußeren Mantel 29 des Verschlußteiles 14 umgeben, welcher auch den freiliegenden Außenumfang des Verschlußteiles 14 bildet. Dieser Mantel 29 schließt zwischen seinen Enden bzw. anschließend an sein inneres Ende an einen Sicherungsflansch 30 an, welcher gegen nach außen gerichtete Kräfte im wesentlichen nur kraft- bzw. reibungsschlüssig gesichert in den Gefäßhals 7 eingreift und gegen nach innen gerichtete Kräfte formschlüssig und spielfrei abgestützt ist, so daß bei Aufbringen einer entsprechend hohen Abzugskraft, die Haltekraft des Sicherungsflansches 30 überwunden und die Austragvorrichtung 1 vom Speichergefäß 2 zerstörungsfrei abgezogen wird. Der im Querschnitt ein Haken- bzw. Einhängeprofil mit einer Sicherungsnut für die Aufnahme des Gefäßhalses 7 bildende Sicherungsflansch 30 ist mit dem Grundkörper 12 nur in einem einzigen und sehr kurzen Axialbereich annähernd starr verbunden, wobei die Länge dieses Axialbereiches wesentlich kleiner als die Außenwand des Gehäuseteiles 14 und höchstens doppelt bis dreifach so groß wie die Wandungsdicke des Mantels 29 bzw. des Gehäuseteiles 13 ist. Der Verschlußteil 14 weist einen an sein inneres Ende anschließenden, ringscheibenförmigen bzw. ebenen Tragflansch 31 auf, welcher über den zum äußeren Ende 27 nicht erweiterten Außenumfang des Mantels 29 vorsteht, die genannte Axialerstreckung hat, einteilig mit dem Mantel 29 ausgebildet ist und wie das innere Ende des übrigen Verschlußteiles 14 an seiner inneren Stirnfläche vollständig berührungsfrei liegt. Die Grenze zwischen dem Grundkörper 12 und dem Sicherungsflansch 30 ist entweder durch den Außenumfang des Mantels 29 und/oder denjenigen des Tragflansches 31 bestimmt.The housing part 13 is from the inner end in the on the outer circumference further closure part 14 used, within this and with this via a plug or snap connection connected, does not protrude beyond the outer end 27 and is on Outer circumference of its inserted longitudinal section of one outer shell 29 of the closure member 14, which also the exposed outer circumference of the closure part 14 forms. This jacket 29 closes between its ends or then at its inner end to a safety flange 30, which essentially against outward forces only non-positively or frictionally secured in the Vascular neck 7 engages and against inward forces is supported positively and without play, so that when applied a correspondingly high pull-off force, the holding force of the securing flange 30 overcome and the discharge device 1 is removed from the storage vessel 2 non-destructively. The cross section of a hook or hanging profile with a Securing groove for receiving the neck 7 forming The securing flange 30 is only in one with the base body 12 single and very short axial area almost rigidly connected, the length of this axial area is significantly smaller than the outer wall of the housing part 14 and at most twice up to three times the wall thickness of the jacket 29 or the housing part 13. The closure part 14 has an annular disk-shaped adjoining its inner end or flat support flange 31, which over the to outer end 27 not expanded outer circumference of the casing 29 protrudes, has the mentioned axial extent, in one piece with the jacket 29 is formed and how the inner end of the remaining closure part 14 on its inner end face is completely non-contact. The boundary between that Base body 12 and the securing flange 30 is either by the outer circumference of the jacket 29 and / or that of Support flange 31 determined.

An den Außenumfang des Tragflansches 31 schließt ein mit Radialabstand vom Mantel 29 liegender und dessen Außenumfang annähernd auf seiner gesamten Länge umgebender Mantel 32 an, der wie der Mantel 29 im Axialschnitt einen Schenkel eines U-Profiles bzw. einen Längs- oder Wandungsteil bildet, wobei der Mantel 29 an die das äußere Ende 27 bildende Stirnwand des Verschlußteiles 14 anschließt, von deren Innenseite der in den Gehäuseteil eingreifende Ansatz vorsteht. In diesem ist der Schaft 17 verschiebbar angeordnet. Das äußere Ende des Mantels 32 geht radial nach außen gerichtet in ein winkel- bzw. hakenförmiges Teil über, wobei der Mantel 32 an einen Stirnteil bzw. Stützflansch 33 anschließt, welcher einen Wandungsteil bzw. eine ringförmige Stirnwand oder eine im wesentlichen ebene Platte bildet, die mit ihrer inneren und/oder äußeren, jeweils annähernd ebenen Stirnfläche in einer zur Achse 11 etwa rechtwinklingen Ebene liegt. Die Wandungsdicke des Mantels 32 und des Stützflansches 33 liegt etwa in der Größenordnung der anhand des Tragflansches 31 beschriebenen Dicke. Der Stützflansch 33 bildet einen Hakenschenkel des winkelförmigen Hakenprofiles und geht an seinem radial äußeren Ende bzw. an seinem Außenumfang in einen Schenkel oder Mantel 34 über, welcher über seine innere Stirnfläche 36 etwa axial vorsteht, jedoch wesentlich weniger weit als der Mantel 32, nämlich weniger als die Hälfte oder ein Drittel davon. Das so gebildete Einhängeprofil mit gegeneinander längsversetzten Teilen 31, 33 kann den Grundkörper 12 am Außenumfang abschirmen und umgreift den Gefäßhals 7 am Innenumfang, am Außenumfang und an der äußeren Stirnfläche, wobei alle genannten Wandungsteile 31 bis 34 einteilig lückenlos dicht geschlossene Wandungen oder Schenkel bilden und der Wandungsteil 34 zur Erzielung einer höheren Federnachgiebigkeit dünner als mindestens einer der übrigen Wandungsteile 31, 32, 33 ist.On the outer circumference of the support flange 31 includes a Radial distance from the jacket 29 and its outer circumference jacket 32 surrounding approximately its entire length, which, like the jacket 29, has one leg of a U profile in axial section or forms a longitudinal or wall part, wherein the jacket 29 to the end wall forming the outer end 27 of the closure part 14 connects, from the inside of the protrudes into the housing part engaging approach. In this the shaft 17 is slidably disposed. The outer end of the jacket 32 goes radially outward into a angular or hook-shaped part, with the jacket 32 on connects an end part or support flange 33, which a wall part or an annular end wall or a essentially flat plate that forms with its inner and / or outer, each approximately flat end face in a plane approximately perpendicular to axis 11 is located. The Wall thickness of the jacket 32 and the support flange 33 is approximately in the order of magnitude based on the support flange 31 described thickness. The support flange 33 forms a hook leg of the angular hook profile and goes on his radially outer end or on its outer circumference in one Leg or coat 34 over, which over its inner End face 36 protrudes approximately axially, but significantly less far than the jacket 32, namely less than half or a third of it. The mounting profile thus formed with Parts 31, 33 which are longitudinally offset from one another can form the base body Shield on the outer circumference and encompasses the neck of the vessel 7 on the inner circumference, on the outer circumference and on the outer End face, all of the wall parts 31 to 34 one-piece, completely sealed walls or legs form and the wall part 34 to achieve a higher spring compliance thinner than at least one of the remaining wall parts 31, 32, 33.

Die in beliebigen Paarungen einteilig miteinander ausgebildeten bzw. eine Montageeinheit bildenden Wandungsteile 32 bis 34 bilden mindestens zwei bzw. drei quer oder annähernd rechtwinklig zueinander liegende sowie in einspringenden Ecken ineinander übergehende Ausricht- und Stützflächen 35 bis 37, von denen jeweils eine einer der Bezugsflächen 6, 4, 5 so zugeordnet ist, daß sie an dieser mit Querspannung rückfedernd anliegt. Von den U-förmig zueinander liegenden Flächen liegt die Außenumfangsfläche 35 des Wandungsteiles 32 im Querschnitt im wesentlichen ganzflächig an der zugehörigen Bezugsfläche 6 an, jedoch ist sie nur durch einen verhältnismäßig kleinen Axialabschnitt dieses Wandlungsteiles 32 und der zugehörigen Umfangsfläche gebildet. Die im wesentlichen ebene, ringscheibenförmige Stützfläche 36 liegt mit dem größten Teil ihrer Fläche an, während die durch eine Innenumfangsfläche gebildete Sicherungsfläche 37 des Wandungsteiles 34 nur an einem an eine Übergangsphase zur Bezugsfläche 4 anschließenden Teil der Bezugsfläche 5 anliegt. Der Wandungteil 34 deckt jedoch die Bezugsfläche 5 am Umfang vollständig ab und steht über diese Fläche 5 zum Speicherraum 9 axial mit einem geringfügig trichterförmig erweiterten Abschnitt vor. The one-piece with each other in any pairings or an assembly unit forming wall parts 32 to 34 form at least two or three transversely or approximately at right angles to each other as well as in recessed Alignment and support surfaces 35 merging into corners to 37, each of which one of the reference surfaces 6, 4, 5 is assigned so that it is at this with transverse voltage resilient. Of the U-shaped to each other The outer peripheral surface 35 of the wall part 32 lies flat in cross section essentially over the entire area of the associated Reference surface 6, but it is only proportional by one small axial section of this conversion part 32 and the associated peripheral surface. The essentially flat, annular disc-shaped support surface 36 lies with the most of its surface area, while that by an inner peripheral surface formed securing surface 37 of the wall part 34 only on one of a transition phase to the reference surface 4 adjoining part of the reference surface 5. The wall part 34, however, completely covers the reference surface 5 on the circumference and stands axially over this surface 5 to the storage space 9 a slightly funnel-shaped section.

Am inneren Ende geht der gegenüber dem Gefäß 2 berührungsfreie Wandungsteil 31 bzw. 32 in ein Mantelprofil 38, nämlich einen am Innen- oder Außenumfang nach innen spitzwinkling verjüngten Konusabschnitt über, welcher mit seinem engeren Ende an den Tragflansch 31 einteilig anschließt und wie dessen radial äußeres Ende ebenfalls gegenüber dem Gefäß 2 berührungsfrei ist. Dadurch ist in diesem Bereich eine Versteifung des Wandungsteiles 32 gegenüber dem Grundkörper 12 gebildet, welche die Übertragung radial nach innen gerichteter Kräfte auf den Grundkörper 12 verhindert. Ferner bildet das Mantelprofil 38 eine Einführschräge beim Einsetzen des Sicherungsflansches 30, die an einer entsprechenden trichterförmigen Erweiterung der Gefäßöffnung 3 gleiten kann, wobei die Trichterform durch eine Phase zwischen den Bezugsflächen 4, 6 gebildet ist. Die Sicherungsfläche 35 ist zweckmäßig nach innen unter wenigen Winkelgraden der Achse 11 angenähert, so daß sie erst mit Querspannung in die Bezugsfläche 6 eingreift, wenn der Tragflansch 31 innerhalb von dieser Bezugsfläche 6 liegt. Der Wandungsteil 32 kann unter dieser Spannung geringfügig radial nach innen verengt werden, so daß er allein durch seine inhärente Federkraft die Abdichtung gegenüber der Bezugsfläche 6 bewirkt. Auch der gegenseitige Eingriff der Flächen 4, 36 bzw. 5, 37 wirkt dicht verschließend, so daß eine dreifache Abdichtung im Bereich dreier im Abstand zueinander liegender Dichtspalte gegeben ist und sich auch die Wirkungen einer Labyrinthdichtung ergeben.At the inner end there is no contact with the vessel 2 Wall part 31 or 32 in a jacket profile 38, namely an acute angle on the inside or outside circumference tapered cone section over which with its narrower End in one piece to the support flange 31 and how the radially outer end of which is also opposite the vessel 2 is non-contact. This makes one in this area Stiffening of the wall part 32 relative to the base body 12 formed, which the transmission is directed radially inward Forces on the base body 12 prevented. Furthermore forms the jacket profile 38 an insertion bevel when inserting the Securing flange 30, the corresponding funnel-shaped Expansion of the vessel opening 3 can slide, the funnel shape being characterized by a phase between the reference surfaces 4, 6 is formed. The securing surface 35 is expediently inward at a few angular degrees of axis 11 approximated so that they only with transverse tension in the reference surface 6 engages when the support flange 31 within this reference surface 6 lies. The wall part 32 can under of this tension are narrowed slightly radially inwards, so that it seals only by its inherent spring force with respect to the reference surface 6. Mutual, too Engagement of the surfaces 4, 36 and 5, 37 acts tightly closing, so that a triple seal in the area given three spaced sealing gaps is and also the effects of a labyrinth seal result.

Die von der Stützfläche 36 abgekehrte und nur über die Wandungsdicke des Wandungsteiles 33 von der Stützfläche 36 entfernte Außenfläche 39 ist im wesentlichen eben ringförmig oder sie liegt etwa in der Ebene des äußeren Endes 27, welches gegenüber dieser Außenfläche 39 auch nach innen versetzt sein könnte. Die innere Stirnfläche des Tragflansches 31 liegt etwa in der Ebene des Überganges zwischen dem Gefäßhals 7 zur zugehörigen Stirnwand des Gefäßbauches 8, so daß der Sicherungsflansch 30 das Innere des Gefäßhalses bis auf einen geringen Ringspalt am Innenumfang des Halses nahezu vollständig ausfüllt und der Verschlußteil 14 im wesentlichen vollständig innerhalb des Sicherungsflansches 30 liegt.The away from the support surface 36 and only on the Wall thickness of the wall part 33 from the support surface 36 removed outer surface 39 is substantially planar or it lies approximately in the plane of the outer end 27, which is also offset inward relative to this outer surface 39 could be. The inner face of the wing 31 lies approximately in the level of the transition between the Vascular neck 7 to the associated end wall of the vascular abdomen 8, see above that the securing flange 30 to the inside of the neck of the vessel almost to a small annular gap on the inner circumference of the neck completely fills and the closure part 14 essentially lies completely within the securing flange 30.

Nach außen sind Teile des Sicherungsflansches 30 jedoch offen, wobei eine ringmantelförmige Öffnung 40 zwischen den Flächen 27, 39 und der äußeren Stirnfläche des Tragflansches 31 gebildet ist, welche vom Außenumfang des Mantels 29 und vom etwa koaxialen Innenumfang des Mantels 32 begrenzt ist. Die gegenüber diesen Mänteln 29, 32 etwa 2- bis 3-fach breitere Öffnung 40 ist nach außen geringfügig bzw. am äußeren, an die Außenfläche 39 anschließenden Ende trichterförmig erweitert und weist einen durch den Tragflansch 31 gebildeten, geschlossenen Boden 41 auf, so daß in die Öffnung 40 aus dem Speicherraum 9 kein Medium gelangen kann.To the outside are parts of the securing flange 30 open, with an annular jacket-shaped opening 40 between the Surfaces 27, 39 and the outer end face of the support flange 31 is formed, which from the outer circumference of the jacket 29 and is limited by the approximately coaxial inner circumference of the jacket 32. The compared to these coats 29, 32 about 2 to 3 times wider opening 40 is slight on the outside outer, adjoining the outer surface 39 funnel-shaped expands and has one through the support flange 31 formed, closed bottom 41, so that in the opening 40 no medium can get out of the storage space 9.

Der Betätigungskopf 20 weist einen aus Kunststoff bestehenden, den Schaft 17 sowie den Düsenkopf aufnehmenden Grundkörper 42 und einen diesen am Außenumfang sowie an der äußeren Stirnseite im wesentlichen vollständig abdeckenden Kappenteil 43 auf, welches aus Kunststoff oder Metall bestehen kann und wesentlich dünnwandiger als der Grundkörper 42 ist.The actuating head 20 has a plastic the shaft 17 and the base body receiving the nozzle head 42 and one on the outer circumference and on the outer End face essentially completely covering cap part 43, which can consist of plastic or metal and is much thinner than the base body 42.

Der im wesentlichen spaltfrei am Außenumfang des Grundkörpers 42 anliegende Mantel des Kappenteiles 43 steht nach innen über den Grundkörper 42 vor und übergreift in Ausgangsstellung den Außenumfang des Verschlußteiles 14 vom Ende 27 her, so daß er etwa um die Dicke des Wandungsteiles 33 sowie etwa in der Mitte zwischen den Wandungsteilen 29, 32 berührungsfrei in die Öffnung 40 eingreift. In der niedergedrückten Pumphub-Endstellung kann das Ende des Kappenmantels an den Kantenflächen von Rippen 44 o.dgl. anliegen, welche den Außenumfang des Verschlußteiles 14 mit dem Innenumfang des Wandungsteiles 32 einteilig verbinden und bis zum Boden 41 reichen, so daß sie in ihrem Bereich zur genannten Versteifung beitragen und der Wandungsteil 32 zwischen den Rippen 44 und der Stützfläche 36 und somit im Bereich der Bezugsfläche 6 seinen nachgiebigsten oder weichsten Federbereich hat.The essentially gap-free on the outer circumference of the base body 42 adjacent jacket of the cap part 43 is on the inside over the base body 42 and engages in the starting position the outer circumference of the closure part 14 from the end 27, so that it is about the thickness of the wall part 33 and about in the middle between the wall parts 29, 32 without contact engages in opening 40. In the depressed Pump stroke end position can the end of the cap jacket to the Edge surfaces of ribs 44 or the like. concern which the Outer circumference of the closure part 14 with the inner circumference of the Connect wall part 32 in one piece and down to floor 41 enough so that they are in their area for stiffening contribute and the wall part 32 between the Ribs 44 and the support surface 36 and thus in the area of Reference surface 6 its most compliant or softest spring area Has.

Das Gefäß 2 bzw. der Gefäßhals 7 besteht zweckmäßig aus Glas bzw. einem Material wesentlich größerer Steifheit als der Sicherungsflansch 30, so daß die Bezugsflächen 4 bis 6 unter der Anpresskraft des Sicherungsflansches 30 nicht nachgeben und wie die Flächen 35 bis 37 als sehr glatte Flächen ausgebildet werden können, wobei sich die jeweilige Bezugsfläche 4 bis 6 in die zugehörige Fläche 35 bis 37 geringfügig eindrükken kann. Dadurch bildet der Sicherungsflansch 30 einen dichten Verschlußstopfen für das Gefäß 2.The vessel 2 or the neck 7 suitably consists of glass or a material much greater stiffness than that Securing flange 30 so that the reference surfaces 4 to 6 below do not give in to the contact pressure of the securing flange 30 and how the surfaces 35 to 37 are formed as very smooth surfaces can be, the respective reference surface 4th to 6 slightly press into the corresponding surface 35 to 37 can. As a result, the securing flange 30 forms a tight plug for the vessel 2.

In der Pumphub- bzw. Betätigungs-Endstellung liegt der Auslaß 21 noch außerhalb des Sicherungsflansches 30 und zwar mit einem Abstand von der Außenfläche 39, der etwa dem 2- bis 4-fachen, insbesondere etwa dem 3-fachen der Dicke des Wandungsteiles 33 entspricht, wobei der Auslaß 21 etwa parallel zur Außenfläche 39 ausgerichtet ist. Als Betätigungs-Handhabe 45 dient die äußere Stirnfläche der Stirnwand des lagefest mit dem Grundkörper 42 verbundenen Kappenteiles 43, welcher im Mantel eine gegenüber dem Auslaß 21 wesentlich erweiterte Durchtrittsöffnung für den auszutragenden Sprühstrahl aufweist. In der Endstellung kann auch der Grundkörper 42 den Verschlußteil 14 am Innen- und/oder Außenumfang übergreifen, bzw. in den Verschlußteil 14 eingreifen und mit einer inneren Stirnfläche am äußeren Ende 27 formschlüssig anschlagen. Die Außenweite des Betätigungskopfes 20 ist größer als seine Axialerstreckung, wobei in der Endstellung seine äußere, gegenüber dem Auslaß 21 nach außen versetzte Stirnfläche in einem Abstand außerhalb der Außenfläche 39 liegt, welcher etwa der Hälfte der Axialerstreckung bzw. der Außenweite des Betätigungskopfes 20 entspricht. Die maximale Hublänge des Betätigungskopfes 20 entspricht etwa der Hälfte der Länge des Sicherungsflansches 30, die gegenüber der Länge des Betätigungskopfes 20 kleiner ist, so daß der Hub etwa einem Drittel der Länge des Betätigungskopfes 20 entspricht.The outlet is in the pump stroke or actuation end position 21 still outside of the securing flange 30 with a distance from the outer surface 39 which is about 2 to 4 times in particular about 3 times the thickness of the wall part 33 corresponds, the outlet 21 approximately parallel is aligned with the outer surface 39. As an operating handle 45 serves the outer end face of the end wall of the fixed position with the base body 42 connected cap part 43, which in the jacket a significantly expanded compared to the outlet 21 Has passage opening for the spray to be discharged. In the end position, the base body 42 can also Overlap closure part 14 on the inner and / or outer circumference, or engage in the closure part 14 and with an inner Strike the end face at the outer end 27. The Outer width of the actuating head 20 is larger than his Axial extent, in the end position its outer, compared to the outlet 21 outwardly offset end face in a distance outside the outer surface 39, which about half of the axial extent or the outer width of the Actuating head 20 corresponds. The maximum stroke length of the Actuating head 20 corresponds to approximately half the length of the Securing flange 30, which is relative to the length of the actuating head 20 is smaller, so that the stroke is about a third corresponds to the length of the actuating head 20.

Erfindungsgemäß ist zum Verschluß der Austragvorrichtung 1 im Nichtgebrauchsfalle eine kappenförmige Abdeckung 46 vorgesehen, welche den Austragkopf 20, die Sicherungsmittel 10, 30 sowie den Hals 7 im wesentlichen vollständig abgedeckt aufnimmt und im Bereich des Betätigungskopfes 20 eine kleinere Innenweite als im Bereich der Sicherungsmittel 10 hat. Die Abdeckung 46 weist einen gegenüber ihrer Stirnwand 48 im Bereich des Betätigungskopfes 20 dickeren und im Bereich der Sicherungsmittel 10 dünneren Kappenmantel 47 dadurch auf, daß in ihrer offenen Stirnseite eine ringförmige Vertiefung 49 vorgesehen ist, welche eine größere Axialerstreckung als der Hals 7 bzw. eine Axialerstreckung hat, die etwa der anhand des Sicherungsflansches 30 erläuterten Erstreckung entspricht.According to the invention for closing the discharge device 1 in A cap-shaped cover 46 is provided when not in use, which the discharge head 20, the securing means 10, 30th and takes up the neck 7 substantially completely covered and a smaller one in the area of the actuating head 20 Has inside width than in the area of the securing means 10. The Cover 46 has one opposite its end wall 48 in Area of the actuating head 20 thicker and in the area of Securing means 10 thinner cap jacket 47 in that in its open end face an annular depression 49 is provided which has a greater axial extent than that Neck 7 or an axial extent, which is about the basis of of the securing flange 30 corresponds to the extent explained.

Im Verschlußzustand liegen innerhalb der Vertiefung 49 vollständig versenkt zwei Sicherungskörper 50, 51, von denen einer anschlagbegrenzt festsitzend an der Abdeckung 46 und der andere begrenzt beweglich am Gefäßhals 7 bzw. gegenüber diesem berührungsfrei nur am Verschluß oder Sicherungsflansch 30 befestigt ist. Der Sicherungskörper 50 ist durch einen ring- und napfförmigen Bauteil aus Blech oder dergl. gebildet, welcher wesentlich dünnwandiger als der Sicherungsflansch 30 ist und diesen mit einer ringscheibenförmig ebenen Stirnwand an der Außenfläche 39 anliegend abdeckt. Der Mantel des Sicherungskörpers 50 umgibt den Außenumfang des Wandungsteiles 34 verhältnismäßig eng und reicht annähernd bis zur genannten Stirnwand des Gefäßbauches 8.In the closed state they lie within the recess 49 completely sunk two fuse bodies 50, 51, one of which one is limited to the cover 46 and the other has limited mobility on the neck 7 or opposite This is contact-free only on the lock or securing flange 30 is attached. The fuse body 50 is through an annular and cup-shaped component made of sheet metal or the like. formed, which is much thinner than the securing flange 30 and this with an annular disc-shaped plane End wall covering the outer surface 39 covers. The coat of the securing body 50 surrounds the outer circumference of the wall part 34 relatively narrow and almost reaches the end wall of the vascular abdomen 8.

Der Sicherungskörper 51 ist entsprechend ring- bzw. napfförmig, liegt mit seiner ringscheibenförmigen Stirnwand am Boden der Vertiefung 49 an und reicht mit seinem Kappenmantel bis an die zugehörige offene Stirnfläche der Abdeckung 46, wobei der Sicherungskörper 51 z. B. durch eine federnd einrastende Schnappverbindung, Einpressen oder Kleben bzw. Schweißen lagefest sitzt. Die Stirnwand des Sicherungskörpers 51 ragt über den engeren Innenumfang der Abdeckung 46 radial nach innen bis annähernd an den Außenumfang des Betätigungskopfes 20, so daß sie eine ringförmige Stirnbegrenzung des engeren Öffnungsbereiches der Abdeckung 46 bildet. Mit der inneren Stirnfläche seiner Stirnwand liegt der Sicherungskörper 51 an der äußeren Stirnfläche der Stirnwand des Sicherungskörpers 50 großflächig an.The securing body 51 is correspondingly ring-shaped or cup-shaped, lies on the floor with its ring-shaped end wall the recess 49 and extends with its cap jacket to to the associated open end face of the cover 46, wherein the fuse body 51 z. B. by a resiliently engaging Snap connection, pressing in or gluing or welding sits firmly. The end wall of the fuse body 51 protrudes radially over the narrower inner circumference of the cover 46 inside to almost the outer circumference of the actuating head 20 so that they have an annular forehead border of the narrower Opening area of the cover 46 forms. With the inner The fuse body 51 rests on the end face of its end wall the outer end face of the end wall of the fuse body 50 large area.

Die beiden Sicherungskörper 50, 51 greifen zerstörungsfrei leicht lösbar über ein Sicherungsglied 52 und ein Gegenglied 53 ineinander, die zweckmäßig als federnde Schnappglieder ausgebildet sind, welche nur durch gegenseitige Längsbewegung in und außer Rast- bzw. Verriegelungseingriff gebracht werden können und etwa in der Mitte zwischen den Enden des Wandungsteiles 34 liegen. Das Sicherungsglied 52 ist durch eine über den Außenumfang des Mantels des Sicherungskörpers 50 vorstehende Verformung, wie eine ringförmig geschlossene Versteifungssicke gebildet, die radial nicht nachgiebig zu sein braucht. Das Gegenglied 53 ist durch eine entsprechende Vertiefung bzw. Nut am Innenumfang des Mantels des Sicherungskörpers 51 gebildet und liegt in einem Bereich, in dem dieser Mantel radial federnd gegenüber dem Kappenmantel 47 aufgeweitet werden kann, ohne daß dieser Kappenmantel 47 selbst federnde Aufweit- bzw. Verengungsbewegungen ausführen müßte.The two securing bodies 50, 51 grip without being destroyed easily detachable via a securing member 52 and a counter member 53 into each other, which is useful as resilient snap members are formed, which only by mutual longitudinal movement be brought in and out of locking or locking engagement can and approximately in the middle between the ends of the wall part 34 lie. The securing member 52 is by a over the outer circumference of the casing of the fuse body 50 protruding deformation, like a closed ring Stiffening bead formed that is not yielding radially needs to be. The counter member 53 is replaced by a corresponding one Indentation or groove on the inner circumference of the casing of the fuse body 51 is formed and lies in an area in which this jacket is radially resilient with respect to the cap jacket 47 can be expanded without this cap jacket 47th even perform resilient expansion or contraction movements would.

Der engere Innenumfang der Abdeckung 46 ist mit einem weiteren Sicherungsglied 54 der genannten Art, z. B. mit einem Schnappglied, einem Drehverschlußglied, wie einem Innengewinde oder dergl. versehen, dessen Innenweite mindestens so groß wie die der Öffnung in der Stirnwand des Sicherungskörpers 51 ist, so daß das Sicherungsglied 54 bei eingesetztem Sicherungskörper 51 gegen Beschädigungen von außen abgeschirmt ist und auch nicht auf ein entsprechendes Gegenglied aufgesetzt werden kann. Wird der Sicherungskörper 51 aus der Abdeckung 46 herausgenommen oder von Anfang an nicht eingesetzt, so kann die Abdeckung 46 zum Verschluß eines Gefäßhalses oder dergl. verwendet werden, der an seinem Außenumfang ein dem Sicherungsglied 54 komplementäres Gegenglied zur formschlüssigen, jedoch zur störungsfrei leicht lösbaren Verbindung aufweist. Über die Innenseite der Stirnwand 48 steht ein zu seinem freien Ende am Außenumfang verjüngter Stopfen 58 einteilig vor, welcher in Verschlußlage in die Gefäßöffnung des Gefäßhalses dichtend eingreifen kann, so daß sich ein sehr dichter Verschluß ergibt.The narrower inner circumference of the cover 46 is with another Securing member 54 of the type mentioned, for. B. with a Snap member, a twist lock member, such as an internal thread or the like. Provided, the inside width at least so as large as the opening in the end wall of the fuse body 51, so that the securing member 54 when inserted Securing body 51 shielded against damage from the outside is and also not to a corresponding counterpart can be put on. If the fuse body 51 from the Cover 46 removed or not inserted from the beginning, so the cover 46 can be used to close a neck of the vessel or the like. Be used on its outer circumference a counter member complementary to the securing member 54 for a form-fitting, but easy to solve problem-free Has connection. Over the inside of the end wall 48 stands a tapered to its free end on the outer circumference Plug 58 in one piece, which in the closed position in the Vascular opening of the neck of the vessel can engage in a sealing manner, so that there is a very tight seal.

Der Sicherungskörper 50 ist mit dem Gefäß 2 bzw. mit dem Sicherungsflansch 30 über eine Schnappverbindung 55 verbunden, die lediglich durch axiales Zusammenfügen der beiden Bauteile 30, 50 federnd einrastet, so daß der Sicherungskörper 50 dann gegen Abziehen formschlüssig bzw. unverlierbar gesichert und im wesentlichen nur durch Zerstörung zu entfernen ist. Das Ende des Kappenmantels ist nach innen zu einem Innenmantel gefaltet, der über seine ganze Länge am Innenumfang des äußeren Mantels anliegt und mit seiner freien Stirnfläche gegen die Stirnfläche des Wandungsteiles 34 gerichtet ist. Dadurch bildet dieser Innenmantel außer einer doppellagigen und im axialen Abstand vom Sicherungsglied 52 liegenden Versteifung des Körpermantels ein innerhalb von diesem und im Abstand vom Außenumfang des Gefäßhalses 7 liegendes Schnappglied 56, das hinsichtlich seiner Radialausdehnung im wesentlichen formstarr ist.The fuse body 50 is with the vessel 2 or with the Securing flange 30 connected via a snap connection 55, the only by axially joining the two Components 30, 50 snaps into place so that the securing body 50 then form-fitting against capturing or captive secured and can only be removed by destruction is. The end of the cap jacket is closed inwards an inner jacket folded over the entire length of the The inner circumference of the outer jacket lies and with its free End face directed against the end face of the wall part 34 is. As a result, this inner jacket forms one double-layered and at an axial distance from the securing member 52 lying stiffening of the body shell within this and at a distance from the outer circumference of the neck of the vessel 7 lying snap member 56, the radial expansion is essentially rigid.

Das zweite Schnappglied 57 ist durch das gegenüber der Bezugsfläche 5 berührungsfreie freie Ende des Wandungsteiles 34 gebildet, wobei diese Endfläche nach Art einer Widerhakenfläche schräg liegen bzw. einspringend konisch ausgebildet sein kann. Wird der Sicherungskörper 50 axial auf die außen freiliegenden Bereiche des Sicherungsflansches 30 aufgesetzt, so läuft das Schnappglied 56 auf den Außenumfang des Wandungsteiles 34 auf, der im weiteren Verlauf federnd radial nach innen gedrückt wird, bis das Schnappglied 57 das Schnappglied 56 unter radialer Aufweitung des Wandungsteiles 34 hinterspringt und dadurch der Sicherungskörper 50 axial formschlüssig gegenüber dem Gefäß 2 gesichert ist.The second snap member 57 is opposite to the Reference surface 5 non-contact free end of the wall part 34 formed, this end surface in the manner of a barb surface lie obliquely or protrude conically can be. If the fuse body 50 axially on the Areas of the securing flange 30 exposed on the outside put on, the snap member 56 runs on the outer circumference of the wall part 34, which resilient in the further course is pressed radially inwards until the snap member 57 Snap member 56 with radial expansion of the wall part 34 springs behind and thereby the fuse body 50 axially is positively secured to the vessel 2.

Der Sicherungskörper 50 kann dennoch gegenüber dem Gefäß 2 bzw. dem Sicherungsflansch 30 verdreht werden, hat gegenüber diesem jedoch im wesentlichen kein Radialspiel. Der Sicherungskörper 50 kann jedoch Axialspiel dadurch haben, daß die Schnappglieder 56, 57 bei an der Außenfläche 39 anliegendem Sicherungskörper 50 einen axialen Abstand voneinander haben. Wird die aufgesetzte Abdeckung 46 abgezogen, so kann sie den Sicherungskörper 50 bis zu gegenseitigem Anschlag der Glieder 56, 57 von der Außenfläche 39 abheben, wonach erst die Glieder 52, 53 außer Eingriff gebracht werden können. Dadurch kann das manuelle Entriegeln der Abdeckung 46 erleichtert bzw. die Verriegelungskraft zwischen den Gliedern 52, 53 erhöht werden. Der Sicherungskörper 50 kann gemeinsam mit dem Sicherungskörper 51 oder nach diesem in die Abdeckung 46 in Verriegelungsstellung eingesetzt und dann erst gemeinsam mit der Kappe 46 durch Aufsetzen auf den Gegenflansch 30 montiert werden, so daß ein erstes Aufsetzen der Abdeckung 46 auf den Gegenflansch 30 zur Montage des Sicherungskörpers 50 führt, der danach nicht wieder abgezogen werden kann.The securing body 50 can still be compared to the vessel 2 or the locking flange 30 has to be rotated this, however, essentially no radial play. The security body However, 50 can have axial play in that the Snap members 56, 57 when the outer surface 39 is in contact Fuse body 50 have an axial distance from each other. If the cover 46 is pulled off, it can Securing body 50 up to the mutual stop of the links 56, 57 lift off the outer surface 39, after which the Links 52, 53 can be disengaged. Thereby the manual unlocking of the cover 46 can be facilitated or the locking force between the links 52, 53 increase. The fuse body 50 can together with the Fuse body 51 or after this in the cover 46 in Locked position used and only together with the cap 46 by mounting on the counter flange 30 be so that a first placement of the cover 46 on the Counter flange 30 leads to the assembly of the fuse body 50, which cannot be removed afterwards.

Durch die über den äußeren Innenumfang der Öffnung 40 vorstehende Stirnwand des Sicherungskörpers 50 ist dann das offene Ende der Öffnung 40 bis nahe an den Außenumfang des Betätigungskopfes 20 abgedeckt, der seinerseits den restlichen und radial weiter innen liegenden Bereich des offenen Endes der Öffnung 40 abdeckt, so daß diese nach außen nur im Bereich eines engen Ringspaltes offen ist und kein Schmutz hineinfallen kann. Eventuell doch in die Öffnung 40 gelangender Schmutz kann sich zwischen den Rippen 44 sammeln, so daß keine Gefahr besteht, daß sich deren wirksame Längserstreckung durch Schmutzansammlungen vergrößert. Der Sicherungskörper 50 bildet gleichzeitig einen Schutzmantel für den Sicherungsflansch 30, so daß dieser nach außen vollständig abgedeckt und gegen Beschädigungen geschützt ist. Der Sicherungsflansch 30 erlaubt auch bei aufgesetzter Abdeckung 46 ein rückfederndes Ausweichen der Austragvorrichtung 1 gegen Querkräfte dadurch, daß der Grundkörper 12 gegenüber dem Sicherungsflansch 30 bzw. dem Einhängeprofil 32 bis 34 um wenige Winkelgrade mit steil ansteigender Federprogression kippen kann. Die genannten Eigenschaften und Anordnungen können jeweils genau, im wesentlichen bzw. ungefähr wie beschrieben oder davon abweichend vorgesehen sein. Auch ist es denkbar, den Grundkörper 12 über die Ebene der Außenfläche 39 nach außen vorstehen zu lassen und/oder den Grundkörper 12 exzentrisch zum Sicherungsflansch 30 vorzusehen.Through the protruding beyond the outer inner circumference of the opening 40 The end wall of the fuse body 50 is then the open one End of the opening 40 to close to the outer periphery of the actuating head 20 covered, which in turn the rest and radially inner region of the open end of the Covering opening 40, so that it is only in the area a narrow annular gap is open and no dirt falls into it can. Possibly reaching the opening 40 Dirt can collect between the ribs 44, so that there is no danger that their effective longitudinal extension enlarged by dirt accumulation. The security body 50 also forms a protective jacket for the Safety flange 30 so that it is completely outward is covered and protected against damage. The safety flange 30 also allows 46 when cover 46 is in place a resilient evasion of the discharge device 1 against Shear forces in that the base body 12 relative to the Securing flange 30 or the suspension profile 32 to 34 um few degrees with steeply increasing spring progression can tip. The properties and arrangements mentioned can each exactly, essentially or approximately like described or provided differently. Is too it is conceivable to base the body 12 over the plane of the outer surface 39 to protrude outwards and / or the base body 12 to be provided eccentrically to the securing flange 30.
