Dr. Pepper Snapple was a company tasked with the production of Dr. Pepper, 7up, Schweppes, Snapple and many other drinks owned by Keurig Dr Pepper. They operated basically as a manufacturer branch, and it wasn’t much of a brand. They were simply delegated with production.
This company was originally the production branch of Cadbury Schweppes until they opted to turn that entity into Dr. Pepper Snapple Group, which basically is the same thing, but owned solely by Keurig. This happened in 2008 and lasted until 2018 when production was rerouted to Keurig directly.
Their logo simply showcased the full name – that is, Dr. Pepper Snapple Group – written in capital grey letters in two lines. The last word, for its part, was reduced in size so that they could keep the same width on both levels. The only other visual element was the splashing image of 2 red drops and 3 blue bubbles (after Dr. Pepper and Snapple).
They usually put this part immediately to the left of the text.
This symbol wasn’t featured in any particularly visible spot. They didn’t put it on the packages of their products or other pieces of labeling. The buildings and production property were labeled, as were the reverse sides on some product packages (but not all, because it’s rather too noticeable).
