Coca-Cola's 2-liter bottles have had a similar contoured design for more than a decade, a change that reportedly prompted a boost in sales for Coke's 2-liter line.

Typically, a pizzeria charges $3 for a 2-liter bottle of Coke. But under the ban, customers would have to buy six 12-ounce cans at a total cost of $7.50 to get an equivalent amount of soda.
