A paperboard carton doubles as a shipping container for articles such as beverage cans and a cooler for containing ice to cool the articles when the carton is opened. The top portion of the carton is breached by removing an opening strip defined by zipper rules. Once breached, the tops and side panels of the carton are opened up to form an upwardly open chimney or skirt into which ice can be placed to cool the contents of the carton. Gussets formed in the lower corners of the cartons insure that water from melting ice does not leak prematurely from the carton.
