Der mit dem ersten Anschlag 34 bzw. den Teilringstegen 38 zusammenwirkende Deckelrand 37 ist ein innerhalb der äußeren Begrenzung des Deckels 11 befindlicher Rand. Dieser bildet sich durch Anlage des Deckels 11 an einem Umfangsflansch 39 des Ventilkörpers 16 derart, daß der Ventilkörper 16 am Deckel 11 fest fixiert ist unter Zwischenschaltung der bereits erwähnten Ringdichtung 19. In die topfartige Ausnehmung des Schließelements 25 ist der behälterinnere bzw. distale Endabschnitt des Abgaberöhrchens 18 vorzugsweise unter Preßsitz eingepaßt.The one with the first stop 34 or the partial ring webs 38 cooperating lid rim 37 is within the outer Limitation of the lid 11 located edge. This forms by contact of the cover 11 on a peripheral flange 39 of the valve body 16 such that the valve body 16 on Cover 11 is firmly fixed with the interposition of already mentioned ring seal 19. In the pot-like The recess of the closing element 25 is the inside of the container or distal end portion of the delivery tube 18 preferably fitted under press fit.

In der ersten Öffnungsstellung gemäß Fig. 2 schließt die Ringdichtung 19 den ersten Zugang 21 zum Austragskanal 20 fluiddicht ab. Der erste Zugang 21 befindet sich in dieser Stellung etwa auf Höhe der Ringdichtung 19. Bei dieser Stellung ist der Ringvorsprung 27 des Ringflansches 26 des topfartigen Schließelements 25 von der behälterinneren Seite der Ringdichtung 19 bereits abgehoben, so daß eine Fluidverbindung zwischen dem Behälterinneren 13 und dem weiteren bzw. zweiten Zugang 23 zum Austragskanal 20 entsteht. Wird das Abgaberöhrchen 18 gemäß Fig. 3 noch weiter in das Behälterinnere hineingedrückt, gibt die Ringdichtung 19 auch den ersten Zugang 21 zum Austragskanal 20 frei, so daß die Fluidverbindung zwischen Behälterinnerem 13 und Austragskanal 20 des Abgaberöhrchens 18 durch beide Zugänge 21, 23 erfolgt. Dementsprechend wird dann eine höhere Austragsmenge erreicht. Bei einer etwas dickeren Ringdichtung 19 ist es denkbar, daß sich der erste Zugang 21 auch in Schließstellung gemäß Fig. 1 im Bereich der Ringdichtung befindet, so daß der erste Zugang 21 unmittelbar von der Ringdichtung 19 geschlossen wird. Dies ist letztlich eine Frage der Dimensionierung und ändert nichts am Funktionsprinzip der beschriebenen Konstruktion.2 closes in the first open position Ring seal 19 the first access 21 to the discharge channel 20th fluid-tight. The first access 21 is in this Position approximately at the level of the ring seal 19. With this Position is the ring projection 27 of the ring flange 26 of the Pot-like closing element 25 from the inside of the container the ring seal 19 already lifted off, so that a Fluid connection between the container interior 13 and the further or second access 23 to the discharge channel 20 arises. The dispensing tube 18 shown in FIG. 3 is still further pressed into the inside of the container gives the ring seal 19 also free the first access 21 to the discharge channel 20, see above that the fluid connection between the interior of the container 13 and Discharge channel 20 of the dispensing tube 18 through both entrances 21, 23 takes place. Accordingly, a higher one Discharge volume reached. With a slightly thicker ring seal 19, it is conceivable that the first access 21 in 1 in the area of the ring seal located so that the first access 21 directly from the Ring seal 19 is closed. Ultimately, this is one Question of dimensioning and does not change anything Principle of operation of the construction described.

Sämtliche Teile mit Ausnahme der Ringdichtung 19, Fluiddichtung 12 und dem Deckel 11 bestehen aus Kunststoff. Die vorerwähnten Dichtungen sind vorzugsweise aus Gummi oder dergleichen elastischem Dichtmaterial hergestellt. Der Deckel 11 besteht vorzugsweise aus Aluminiumblech, ebenso wie der nicht näher dargestellte Behälter.All parts with the exception of the ring seal 19, Fluid seal 12 and the cover 11 are made of plastic. The aforementioned seals are preferably made of rubber or the same elastic sealing material. The lid 11 is preferably made of aluminum sheet, as is the Containers not shown.

Das dem zweiten Zugang 23 zum Austragskanal 20 zugeordnete topfartige Schließelement 25 hat im übrigen noch den Vorteil, daß die erste Öffnungsstellung des Abgabeventils auch durch seitliches Kippen des Abgaberöhrchens samt Zerstäuberkappe erreicht wird. Eine Fluidverbindung zwischen dem Behälterinneren 13 und dem Austragskanal 20 über den zweiten Zugang 23 wird schon dann erreicht, wenn ein Teil des Ringvorsprungs 27 von der behälterinneren Seite der Ringdichtung 19 abhebt.That assigned to the second access 23 to the discharge channel 20 Pot-like closing element 25 also has the advantage that the first opening position of the dispensing valve also through the dispensing tube and atomizer cap are tilted to the side is achieved. A fluid connection between the Container interior 13 and the discharge channel 20 via the second Access 23 is already reached when part of the Ring projection 27 from the inside of the container Ring seal 19 stands out.
