When does a can typically get classified as a "flipper"?

A can typically gets classified as a "flipper" when it has one bulged end. This bulging indicates that there is a buildup of gas inside the can, often due to spoilage or fermentation of the contents. The bulging creates an unstable condition, which can lead to the can potentially bursting if pressure continues to increase.

Understanding this classification is important for safety, as cans that show signs of bulging should not be consumed. They are often considered hazardous, as the contents may be spoiled. This definition helps those in food service and culinary roles to recognize potential food safety risks and take appropriate action.
