The can top end includes a top end ring, that can be connected to the opening edge () of the can body () and borders a removal opening () and a sealing diaphragm () arranged on the top end ring and covering the removal opening. A cylindrical, seamless can body blank () is produced. Following trimming of the opening edge () of the can body blank (), a cylindrical ring () is separated therefrom. The height of the can body blank () is preset in such a way that the can body () is formed during separation of the cylindrical ring (). The scrap portion can also be reduced by the method during production of can bodies and top end rings.
