ABSTRACT:
This specification discloses a can end having push-in closures, one closures being smaller than the other for venting and/or pressure releasing purposes. At least the smaller closure having a supplementary sealant connection about which the closure hinges when it is opened. The supplementary sealant connection acts to prevent the closure becoming detached from the can end in the event that the main hinge for the closure is broken. The supplementary connection is achieved either by extending the sealant to cover an adjacent surface of the closure in a direction away from the connection or by increasing the thickness of the sealant covered in the area of the main hinge.
