Abstract
An opening arrangement for cans which are made of sheet steel. The opening arrangement has two preferably U-shaped punched lines provided in the lid of the can. The punched lines wholly penetrate the can lid (2) and form two opposing tongues, which are separated by a narrow intermediate portion of the can lid. The punched out tongues as well as the intermediate portion are jointly covered by an inner cover strip fixed to the inside of the can lid which bridges over and seals the punched lines forming the tongues. On opening the can the two tongues are turned in unison, the intermediate portion acting as an axis of rotation, so that the tongues are placed at an angle and an opening in the lid is established.
