摘要：A pour spout (1) for pouring a fluid, such as fuel, by gravity from a container (2)to a tank (3) includes a conduit (4,5) having one end connected to the fuel container andhaving a second end to be positioned within the neck of the tank. A sleeve (5) is mountedfor sliding movement within a tube (4) of the conduit and the outer end of the sleevecarries a closure (17) which closes off the discharge end of the conduit. A vent tube (20) isdisposed within the conduit and has an inlet end (23) which is adapted to communicatewith the fuel tank when the closure is in the open position. A check valve (24,25) ismounted within the vent tube and permits the flow of fuel vapour and air from the tankthrough the tube to the container, but prevents flow of fuel in the opposite direction. Anannular collar (29) is mounted on the conduit and with the collar engaged with the neckof the fuel tank, a downward force applied through the container on the sleeve (5) willopen the closure to admit fuel through the conduit to the tank. The collar (29) is
adjustably mounted along the length of the fluid conduit to accommodate tank necks ofdifferent configurations and the closure (17) carries a rotatable tab (38) which enclosesthe inlet of the vent tube when the closure is in the closed position to prevent foreignmaterial from entering the vent tube, but permits limited vapour and air flow to eliminate
a buildup of pressure or vacuum in the fuel container. By rotating the tab, the tab can bebrought into sealing engagement with the inlet of the vent tube to prevent vapour orliquid flow therethrough.
