A spittoon is a bowl or other container that's made for spitting into. Your tobacco-chewing uncle might keep a spittoon on his porch. Spittoons are fairly old fashioned — in the late 19th and early 20th centuries, it was common to find public spittoons, usually made of brass, in places like banks and hotels.
Nowadays, totally unnacceptable, even when crossing rivers, would you---you decide!
Cache is a tube, 100mm long , not to be used as a Spittoon BYO!!
