Never seen those before, I'm guessing it's a local franchise's brand for their non-Coke flavours. You don't see Coke bottlers giving brand names to their other flavours very often though, I'm wondering if the practice was discouraged or prohibited by the head office.
I don't know I have several designs of soda water bottles that say property of cocacola but these are the first that I have gotten a chance to purchase that have the brand name of quality brand soda water .I have seen a few in other collections
