A hollow tube (138) attached to a container (12) of fluid is provided with an end cap (144) in which is formed a fluid discharge opening (154). A slide valve (108) on the exterior of the tube is biased into a closed position, percluding fluid transfer until the discharge opening is inside a receiving vessel. An air vent tube (158) within the conduit admits air into the container. Fluid filling a receiving container closes the air vent tube when the receiving vessel is filled. The air vent tube includes one or more capillary sections (162, 166) of reduced inner diameter relative that of the air vent tube. A seal (186) is provided for closing the air vent tube when the slide valve is in its closed position. A relief passageway (192) with a one-way valve (194) permits fluid to drain from the vent tube following each fluid transfer. |
