(under subclass 285) Filling devices having plural passage means which extend substantially side by side with outlets extending to approximately the same terminus, one said passageway, being for the flow of air into the supply container and the other for the flow of liquid therefrom.
(1) Note. The filling relation arises from the fact that flow from the supply is stopped when the level of liquid in the receiver rises to the bottom of the vent passage. Complete closing of the receiver inlet except for the flow passages is not required.
SEE OR SEARCH THIS CLASS, SUBCLASS:
308, for similar arrangements; however, where the liquid flow line additionally contains a flow controlling means.

222, Dispensing, 479, for dispensers having coterminously arranged flow paths where the air to the supply is not blocked by the level of material in the receiver.
