Coca-Cola Chile is set to launch new 2.5-litre returnable bottles of Coke in response to consumer demand. The new range is a worldwide first for the soft drinks giant. Coca-Cola Chile general manager Francisco Crespo said the bottles will reach Chilean supermarkets this weekend. "Consumers were asking for this because they know it is cheaper to buy returnable bottles, apart from the fact that 2.5 litres lasts longer," Crespo said.
