Continual Flame cannot be “smothered or quenched”, be put into a pocket?

@JeremyECrawford Continual Flame cannot be "smothered or quenched", can an object with the spell be put into a pocket, pouch or backpack.

Continual flame can be covered, hidden, etc. You could put it in your backpack, for instance. But doing so doesn't quench the flame. #DnD https://t.co/uyvk4W9oNx
