Abstract
A break-away gas cap includes an inner member having a central portion adapted to close and seal an opening in gasoline tanks, such as the gasoline fill neck of an automobile, and an outer shell that engages and is carried by the inner member and provides a hand-engaging surface to be used to insert and remove the gas cap. The inner member includes weakened portions between its closure portion and the portions carrying the outer shell to enhance breakage of the outer shell from the inner member in the event of impact, such as an automobile accident, without affecting the closure and seal of the gasoline tank.
