  • the mixing machine applies suction to dispensing tube 104
  • the flexible umbrella valve 106 opens in response thereto.
  • the valve stem 66 will have been previously moved to its "open" position when the cap portion 76 is placed on the bottle.
  • Liquid from the container 14 is drawn upwardly through the curved dip tube 26 by the metering insert 30 and into the bore 74 inasmuch as the openings 36 are in communication therewith due to the fact that valve stem 66 has been moved downwardly to its open position, as previously described.
  • the interior of bore 74 then is permitted to bypass the umbrella valve 106 and travels into the interior of the dispensing tube 104.
  • the umbrella valve 106 prevents backflow from the dispensing tube 104, since the umbrella valve 106 seals the open end of receiver 86.
  • the removal of the cap from the bottle causes the spring actuated valve stem 66 to close inasmuch as the valve stem 66 is moved upwardly to the position illustrated in Figure 3 so that the openings 36 are closed by the valve body 68 which prevents liquid from passing from the interior of valve body 32 into the interior of bore 74.
  • the venting membrane 62 permits gas pressure or vacuum in the bottle to dissipate when the cap has been removed from the container.
  • the venting membrane 62 allows venting of gas, but not liquid, to relieve gas pressure or vacuum in the bottle, but stops liquid flow such as if the bottle tips over.
  • the dispensing system of this invention includes an umbrella valve which opens automatically under draw-off pressure and which closes when pressure is removed, thereby eliminating reverse flow from the dispensing tube. Accordingly, it can be seen that the invention accomplishes at least all of its stated objectives.

Abstract

Système de distribution en boucle fermée destiné à être utilisé sur un récipient de liquide tel qu'une bouteille ou analogue pour la distribution de liquide contenu dans la bouteille. L'orifice de sortie de la bouteille est fermé par une bonde dotée d'une valve à l'intérieur de ladite bonde, qui est ouverte quand le bouchon du récipient est monté sur le récipient, mais qui se ferme automatiquement lorsque le bouchon est enlevé du récipient. Un tube plongeur s'étend vers le bas depuis la bonde introduite dans le récipient et se trouve en communication avec la valve si bien que du liquide se trouvant dans la bouteille peut être prélevé par ledit tube. Un bouchon de fermeture est monté sur la bouteille et possède un tube de distribution qui s'étend depuis ledit bouchon pour la distribution de liquide contenu dans le récipient à une machine de mélange ou analogue. Un valve de non-retour est associée au bouchon pour empêcher l'écoulement à contre-courant du tube distributeur vers le récipient et pour permettre l'écoulement de liquide du récipient au tube de distribution en réponse à une aspiration appliquée au tube de distribution.
