Disclosed herein is a sealable bottle. The bottle includes a pouring spout portion which projects from the bottle and has an interior surface defining a fluid flow passage in communication with the interior volume of the bottle. The spout may have a length and diameter sufficient to activate filler neck closure members (e.g. flaps, valves, or other closure members). At least a portion of the spout may be devoid features which could compromise the operation of the closure mechanism in a fuel tank filler neck. The spout may include threads operable to engage a cap on the end of the spout. The threads may be separated by clearance features operable to avoid interference with a capless fuel system.

1. A sealable, capless fuel-tank filler system bottle, comprising: a bottle that includes: a storage portion defining an interior volume to retain a liquid therein;a pouring spout extending from the storage portion and defining a throat in fluid communication with the interior volume of the storage portion, the pouring spout defining an opening connected to the throat for discharging the liquid, the pouring spout including an external coupling mechanism to secure a cap thereon and defining a clearance feature on the exterior of the pouring spout that interrupts the coupling mechanism, the clearance feature forming a flat region having a diameter at a height lower than the coupling mechanism and extending through the coupling mechanism to the pouring spout opening, the clearance feature being sufficiently smoother than the external coupling mechanism to avoid catching on an interior protrusion within a fuel-tank filler neck. 2. The bottle of claim 1, further comprising a cap that engages the coupling mechanism to close the opening. 3. The bottle of claim 2, wherein the cap engages the coupling mechanism, fluidly sealing the spout opening. 4. The bottle of claim 1, wherein the coupling mechanism substantially surrounds the exterior of the spout. 5. The bottle of claim 1, wherein the coupling mechanism has a radial high portion and a radial low portion that is disposed proximally from the radial high portion, wherein the radial high portion tends to catch on an internal portion of the fuel-tank filler neck when aligned therewith, wherein when the bottle is rotated to align the clearance feature with the internal protrusion thereby releasing the radial high portion from the protrusion and the bottle can be withdrawn axially. 6. The bottle of claim 1, wherein the clearance feature extends beyond the coupling mechanism away from the opening. 7. The bottle of claim 6, wherein the spout includes a first portion that is proximal to and adjacent the coupling mechanism, the clearance feature extending into the first portion to provide tactile feedback when the bottle is rotated within a filler neck and an internal protrusion of the filler neck enters the clearance feature. 8. The bottle of claim 7, wherein the first portion has an external diameter similar to that of the coupling mechanism. 9. The bottle of claim 1, wherein the clearance feature is oriented axially to permit withdrawal of the spout in a substantially straight axial direction from the filler neck. 10. The bottle of claim 1, wherein the clearance feature has an external surface that has a radial height lower than the coupling mechanism. 11. The bottle of claim 1, wherein the spout has an axis, and the clearance feature has an external surface with a diameter less than the spout measured about the spout axis. 12. The bottle of claim 1, wherein the clearance feature includes a flat external surface. 13. The bottle of claim 1, wherein the clearance feature comprises a plurality of clearance features. 14. The bottle of claim 13, wherein the clearance features are disposed on diametrically opposite sides of the spout. 15. The bottle of claim 13, wherein the clearance features comprise four clearance features. 16. The bottle of claim 1, wherein the coupling mechanism comprises threads, and the clearance feature interrupts the threads along an axial strip forming reduced flat threads extending into the flat region such that a wall of the pouring spout and the threads together form the flat region. 17. The bottle of claim 16, wherein the threads have peaks and valleys, and the clearance feature has an external surface that is radially lower than the peaks. 18. The bottle of claim 17, wherein the external surface of the clearance feature extends radially lower than the valleys. 19. The bottle of claim 16, wherein the threaded portion occupies between about 5% and 20% of the length of the pouring spout portion. 20. The bottle of claim 16, wherein the clearance feature extends beyond the threads away from the opening. 21. The bottle of claim 1, wherein the coupling mechanism is disposed adjacent the opening. 22. The bottle of claim 1, wherein the container portion contains a fuel additive. 23. A method for the delivery of a fluid product through a fuel-tank filler neck comprising: inserting a pouring spout of a bottle into the filler neck of a fuel-tank, with the pouring spout extending from a storage portion, the pouring spout having a throat in fluid communication with the interior volume of the storage portion, the pouring spout defining an opening connected to the throat for discharging the liquid, the pouring spout including an external coupling mechanism to secure a cap thereon and defining a clearance feature on the exterior of the pouring spout that interrupts the coupling mechanism, the clearance feature forming a flat region having a diameter at a height lower than the coupling mechanism and extending through the coupling mechanism to the pouring spout opening, the clearance feature being sufficiently smoother than the external coupling mechanism to avoid catching on an interior protrusion within the fuel-tank filler neck;engaging at least a first door within the filler neck with the pouring spout;emptying the fluid product into the fuel-tank;withdrawing the pouring spout of a bottle from the filler neck of the fuel-tank;rotating the bottle in response to encountering an interference between the coupling mechanism and the filler neck;stopping rotation in response to placing the clearance feature proximal to a portion of the filler neck causing the interference; and continuing to withdraw the bottle from the filler neck.
