Abstract: 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.

Abstract: The present disclosure relates to a container having a fuel additive, and a spout extending from and in fluid communication with the container. The spout includes an elongated engagement nozzle having a radially outer surface extending to a distal tip of the bottle. The elongated engagement nozzle defines an opening for discharging the fluid from the bottle and has an axial length and radial diameter dimensioned for insertion into the throat of a capless fuel system sufficiently far to contact and operate a lock disengagement element within the throat and to open an internal closure within the throat. A cap attachment portion is configured for attaching a cap to close the engagement nozzle opening, and is disposed clear of the engagement nozzle outer surface.
