A pour spout for pouring a fluid, such as fuel, by gravity from a container to a tank. The spout includes a conduit having one end connected to the fuel container and having a second end to be positioned within the neck of the tank. A sleeve is mounted for sliding movement within the conduit and the outer end of the sleeve carries a closure which closes off the discharge end of the conduit. A vent tube is disposed within the conduit and has an inlet end which is adapted to communicate with the fuel tank when the closure is in the open position. A check valve is mounted within the vent tube and permits the flow of fuel vapor and air from the tank through the tube to the container, but prevents flow of fuel in the opposite direction. An annular collar is mounted on the conduit and with the collar engaged with the neck of the fuel tank, a downward force applied through the container on the sleeve will open the closure to admit fuel through the conduit to the tank. The collar is adjustably mounted along the length of the fluid conduit to accommodate tank necks of different configurations. The closure carries a rotatable tab which encloses the inlet of the vent tube when the closure is in the closed position to prevent foreign material from entering the vent tube, but permits limited vapor and air flow to eliminate a buildup of pressure or vacuum in the fuel container. By rotating the tab, the tab can be brought into sealing engagement with the inlet of the vent tube to prevent vapor or liquid flow therethrough.

A pour spout for pouring a fluid, such as fuel, by gravity from a container to a tank. The spout includes a conduit having one end connected to the fuel container and having a second end to be positioned within the neck of the tank. A sleeve is mounted for sliding movement within the conduit and the outer end of the sleeve carries a closure which closes off the discharge end of the conduit. A seal is incorporated to prevent the entry of foreign particulate material into the sliding interface formed between the conduit and sleeve. The seal is provided by an annular skirt which overlaps with an annular flange together with an annular jacket of resilient foam material surrounding the sleeve and conduit at the location of the sliding interface.
