How to turn off a Zippo Handwarmer on-the-go

There is another way to turn off a zippo handwarmer on-the-go, so safer and most likely easier.
Keep the handwarmer in the felt pouch. Turn the handwarmer upside down and with one movement hit the handwarmer in your hand so that the burner falls off into the cap. Then keep the handwarmer upside down for a minute or two, open the handwarmer, replace the burner and then keep it for use another time!
