In Fig. 3 ist eine zweite Ausbildungsform der erfindungsgemässen Vorrichtung dargestellt. Sie unterscheidet sich bezüglich Fig. 1 in der Form des Dichtelements 33 und dadurch, dass kein Spiel 36 für den Haltewulst 32 in der umlaufenden Nut 30 vorhanden ist. Im linken Teil der Figur ist der Vorratsbehälter 12 nicht vollständig, im rechten Teil der Figur vollständig eingeschraubt. Bei dieser Ausbildungsform weist das Dichtelement 33 Dichtlippen 46,48 auf, die im Querschnitt V-förmig sind.In Fig. 3 is a second form of training shown device according to the invention. she differs with respect to Fig. 1 in the form of Sealing element 33 and in that no game 36 for the Retaining bead 32 is present in the circumferential groove 30. in the the left part of the figure is not the reservoir 12 complete, complete in the right part of the figure screwed. With this type of training this shows Sealing element 33 sealing lips 46,48, which in cross section Are V-shaped.

Beim Einschraubevorgang gelangt die untere Dichtlippe 46 in Kontakt mit der stirnseitigen ringförmigen Dichtfläche 20 des Vorratsbehälters 12. Beim weiteren Einschrauben wird die untere Dichtlippe 46 in Richtung der oberen Dichtlippe 48 bewegt, die immer in Kontakt mit dem Boden 27 der Ausnehmung 26 steht. Nach dem Öffnen des Ventils 22 des Vorratsbehälters 12 befindet sich im Innenraum 44 ein höherer Druck als in der Umgebung. Durch diese Druckdifferenz bedingt wirkt eine Kraft, die die untere Dichtlippe 46 an die stirnseitige ringförmige Dichtfläche 20 des Vorratsbehälters 12 und die obere Dichtlippe 48 gegen den Boden 27 drückt, und somit eine vollständige Abdichtung zwischen dem Innenraum 44 und der Umgebung schafft. Im vollständig eingeschraubten Zustand des Vorratsbehälters 12 liegt die untere Dichtlippe 46 derart auf der Dichtfläche 20 auf, sodass der Normalvektor des Teils der Oberfläche der unteren Dichtlippe, der an der Dichtfläche 20 anliegt, parallel zur Längsachse L ist.When screwing in, the lower sealing lip 46 in contact with the front annular sealing surface 20 of the storage container 12. When screwing in further the lower sealing lip 46 in the direction of the upper Sealing lip 48 moves, always in contact with the ground 27 of the recess 26 is. After opening the valve 22 of the storage container 12 is located in the interior 44 a higher pressure than in the environment. Through this Due to the pressure difference, a force acts that the lower one Sealing lip 46 on the front annular sealing surface 20 of the storage container 12 and the upper sealing lip 48 presses against the floor 27, and thus a complete Sealing between the interior 44 and the environment creates. When fully screwed in Storage container 12, the lower sealing lip 46 is such on the sealing surface 20 so that the normal vector of the Part of the surface of the lower sealing lip, which on the Sealing surface 20 rests, is parallel to the longitudinal axis L.

Beim Ausdrehen des Vorratsbehälters 12 aus dem Verbraucherelement 13 schliesst das Ventil 22 bevor die Abdichtung zwischen dem Ventil 22 und der Umgebung aufgehoben ist.When unscrewing the reservoir 12 from the Consumer element 13 closes the valve 22 before the Seal between the valve 22 and the environment is canceled.

Beim Verbraucherelement 13 kann es sich beispielsweise auch um einen Hahn, einen Schieber und dergleichen handeln. Selbstverständlich ist es auch denkbar, dass das Anschlusselement 16 mittels einer Leitung oder eines Schlauches mit dem Vorratsbehälter 12 verbunden ist.The consumer element 13 can be, for example also a cock, a slide and the like act. Of course, it is also conceivable that Connection element 16 by means of a line or Hose is connected to the reservoir 12.
