This throat spray has a long nozzle designed to deliver the oxygenated compounds to the back of the throat as well as the base of the tongue.
After spraying those areas you should pull the nozzle back a bit and let one long spray disperse throughout the mouth.
Oxygen is used to foil the sulfur compound producing bacteria (those responsible for bad breath). The long nozzle allows you to reach those hard to get places and give them a nice shot of the oxygenated spray.
