What is a can called when it bulges at one end when the opposite end receives pressure?

The correct term for a can that bulges at one end due to pressure on the opposite end is a "flipper." In the context of canned foods, this phenomenon occurs when the contents of the can produce gas, often as a result of spoilage or fermentation. This buildup of gas can create excessive pressure inside the can, leading to the bulging effect, which is an important indicator of potential food safety issues.

Identifying a "flipper" can is crucial for food safety, as consuming contents from a can that exhibits this characteristic can pose health risks. Recognizing the signs of compromised packaging helps maintain proper food handling practices in culinary operations. Other terms listed do not accurately describe the condition where a can bulges due to internal pressure.
