Claims
- 1. A pour spout for conducting fluid from a container to a tank, comprising fluid conduit means having a first end defining a cap to be connected to a container for fluid and having a second end adapted to be disposed in communication with a neck of a tank, said fluid conduit means includes an outer conduit and a sleeve disposed concentrically within said conduit and slidable relative to said conduit, said outer conduit and sleeve defining a sliding interface therebetween, closure means for preventing flow of fluid through said fluid conduit means, said closure means having a closed position where said closure means seals the second end of said fluid conduit means and having an open position, means responsive to introducing said fluid conduit means into said tank neck for releasing said closure means and permitting fluid to flow through said fluid conduit means into said tank, and sealing means for preventing particulate foreign material from entering into said sliding interface, said sealing means comprises an annular skirt spaced from said outer conduit and depending from said cap and an upstanding annular flange projecting from said outer conduit, said skirt and flange overlapping to form a tortuous path for preventing the entry of foreign particulate material to said interface.
- 2. The spout of claim 1, wherein said closure means comprising a valve member connected to said sleeve.
- 3. The spout of claim 2, and including biasing means for biasing said valve member to a closed position.
- 4. The spout of claim 3, wherein said biasing means comprises a spring disposed between said conduit and said sleeve.
- 5. The spout of claim 3, and including abutment means projecting radially from said conduit and disposed to engage the neck of the tank, whereby manual longitudinal movement of said sleeve relative to said conduit after said abutment is engaged with said neck, will move said closure means to the open position.
- 6. The spout of claim 5, wherein said abutment means comprises an annular collar disposed on the outer surface of said conduit.
- 7. The spout of claim 6, wherein said collar is mounted for longitudinal movement on said conduit and said spout includes adjusting means for adjusting the position of said collar on said conduit.
- 8. The spout of claim 7, and including locking means for locking said collar relative to said conduit.
- 9. The spout of claim 8, wherein said adjusting means comprises a threaded connection between said collar and said conduit, said threaded connection comprising an internal thread on said collar and an external thread on said conduit, and said locking means comprising a projection on said internal thread and engageable with an interruption on said external thread.
- 10. The spout of claim 5, and including adjusting means for adjusting the position of said abutment means on said conduit.
- 11. The spout of claim 1 further including resilient filter means disposed between the skirt and flange and outer conduit and sleeve at the location of said sliding interface.
- 12. The spout of claim 11 wherein said resilient filter means comprises an annular jacket of resilient foam material.
- 13. The spout of claim 12 wherein said foam material is polyethylene.
