c.1710, from Fr. cantine "sutler's shop," from It. cantina "wine cellar, vault." Perhaps another of the many meanings, now obsolete, that were applied to L. canto "corner;" in this case, perhaps "corner for storage." Extended to "refreshment room at a factory, school, etc." from 1870. Meaning "small tin for water or liquor, carried by solders on the march, campers, etc." is from 1744.
