In PK Gum What Does The P and The K Stand For?

Answer 1

"Packed tight, Kept Right"

(it was the first candy-coated gum produced by Wrigley's). [1]

"...As the economy slowly recovered from the hardships of the crisis, Wrigley maintained its strong position in the market under the leadership of Wrigley's only son, Philip K. Wrigley. The company made headway into the British market, establishing a factory there in 1927 and introducing a pellet-shaped brand of gum. Called P.K, the brand was named for the company's slogan, "Packed tight, Kept right," not for Philip Wrigley's initials as many had claimed. ..." [2]
