Abstract
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.
